Demodulation reference signal bundling and frequency hopping

Methods, systems, and devices for wireless communication are described to support phase continuity in uplink transmissions within a bundle interval. In a first example, a user equipment (UE) may determine bundle intervals for an uplink channel transmission based on a transmission time interval (TTI) format pattern and a bundle size. Bundle intervals may start on a next available uplink TTI after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. In a second example, the UE may use frequency resources for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval. In a third example, the UE may not bundle some repetitions of the uplink channel transmission in a same bundle interval, and may use different frequency resources for the repetitions, based on one or more phase continuity rules.

FIELD OF TECHNOLOGY

The following relates to wireless communication, including demodulation reference signal (DMRS) bundling and frequency hopping.

BACKGROUND

A UE may transmit multiple repetitions of an uplink transmission, for example, to increase communication quality of the uplink transmission.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support demodulation reference signal (DMRS) bundling and frequency hopping. Generally, the described techniques provide for applying phase continuity to uplink transmissions within a bundle interval (e.g., a time interval or time domain window for maintaining phase continuity across one or more transmissions). In a first example, a user equipment (UE) may determine bundle intervals for an uplink channel transmission based on a transmission time interval (TTI) format pattern and a bundle size. For example, bundle intervals may start on a next available uplink TTI (e.g., an uplink or flexible TTI, a TTI configured or available for uplink transmissions) after an end of a preceding bundle interval or from a next set of multiple uplink repetitions that meet one or more conditions for maintaining phase continuity after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI.

In a second example, the UE may use frequency resources (e.g., a frequency hop) for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval or an index of a transmission occasion for one or more repetitions. For example, repetitions transmitted in a first bundle interval or first transmission occasion may use frequency resources (e.g., a first frequency hop) associated with the index of the first bundle interval or first transmission occasion, respectively. Repetitions transmitted in a second bundle interval or second transmission occasion may use frequency resources (e.g., a second frequency hop) associated with the index of the second bundle interval or second transmission occasion, respectively. In a third example, the UE may bundle (e.g., maintain phase continuity for) one or more repetitions of the uplink channel transmission in a first bundle interval, but may not bundle one or more other repetitions of the uplink channel transmission in the same bundle interval, for example, based on one or more phase continuity rules (e.g., a time between repetitions within which the UE is capable of maintaining phase continuity). In such cases, the UE may switch frequency resources (e.g., frequency hops) each time phase discontinuity is experienced (e.g., within a bundle interval or when switching between bundle intervals, or both).

A method for wireless communication at a user equipment (UE) is described. The method may include receiving, from a base station, a control message configuring the UE to transmit a set of multiple repetitions of an uplink channel, transmitting a first repetition of the set of multiple repetitions of the uplink channel in a first available TTI of a first bundle interval of a set of multiple bundle intervals, and transmitting a second repetition of the set of multiple repetitions of the uplink channel in a second available TTI of a second bundle interval of the set of multiple bundle intervals, each bundle interval of the set of multiple bundle intervals having a respective starting time corresponding to a respective starting time of a respective available TTI that occurs after an end of a respective preceding bundle interval of the set of multiple bundle intervals.

DETAILED DESCRIPTION

A user equipment (UE) may perform bundling (e.g., demodulation reference signal (DMRS) bundling) for one or more sets of repetitions of an uplink channel transmission to a base station. Bundling may include maintaining phase continuity across a set of repetitions of the uplink channel transmission, for example, to support joint channel estimation for the set of repetitions at the base station.

A bundle size may define a number of consecutive transmission time intervals (TTIs) for a bundle interval, in which a set of repetitions of the uplink channel transmission may be bundled. As described herein, a bundle interval may refer to a time interval or a time domain window (e.g., of a defined length) over which DMRS or other bundling (e.g., maintaining a phase continuity) is applied or is configured to be applied. The UE may be configured with or determine a bundle size for a set of bundle intervals that each include a set of bundled repetitions of the uplink channel transmission. Some bundle intervals may not include any uplink TTIs (e.g., based on a TTI format pattern) and the UE may be unable to apply DMRS bundling (e.g., maintain phase continuity) in such bundle intervals. Additionally, or alternatively, a bundle interval may include one or more uplink TTIs that may not support phase continuity for repetitions of the uplink channel transmission within the bundle interval (e.g., based on one or more phase continuity rules).

The present disclosure provides techniques for applying phase continuity to uplink transmissions within a bundle interval, where a UE may be configured to identify a bundle interval and/or one or more bundle interval parameters associated with the phase continuity (e.g., DMRS bundling). The UE may identify multiple bundle intervals, which may represent multiple, non-overlapping time domain windows for bundling repetitions of an uplink channel transmission. Each bundle interval may be determined based on a semi-static slot (e.g., TTI) format configuration (e.g., a cell-specific configuration or a UE-specific configuration). In a first example, the UE may determine bundle intervals for the uplink channel transmission based on a TTI format pattern and the bundle size. For example, a first bundle interval may start from a first available uplink TTI (e.g., an uplink TTI or a flexible TTI configured or available for uplink transmissions) scheduled for transmission of the uplink channel transmission or from multiple uplink TTIs scheduled for transmission of repetitions of the uplink channel transmission that meet one or more conditions for maintaining phase continuity.

For example, the transmission of multiple repetitions of the uplink channel (e.g., in that meets the one or more conditions) may support maintaining phase continuity for repetitions of the transmissions of the uplink channel and at least one other repetition of the uplink channel. In some cases, the following bundle intervals may start on a next available uplink TTI (e.g., an uplink TTI or a flexible TTI configured for uplink transmissions) after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. In some cases, the following bundle intervals may start on an uplink TTI associated with uplink repetitions that meet the one or more conditions, after an end of a preceding bundle interval.

In a second example, the UE may use frequency resources (e.g., a frequency hop) for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval or an index of a transmission occasion for one or more of the repetitions. In some cases, all repetitions transmitted in a first bundle interval may use frequency resources associated with the index of the first bundle interval (e.g., a first frequency hop). Similarly, all repetitions transmitted in a second bundle interval may use frequency resources associated with the index of the second bundle interval (e.g., a second frequency hop). In some cases, consecutive bundle intervals may be associated with consecutive indexes (e.g., whether or not a bundle interval includes an uplink TTI). In some other cases, bundle intervals including an uplink TTI (e.g., an uplink TTI or a flexible TTI configured for uplink transmissions) may be associated with consecutive indexes, while other bundle intervals (e.g., not including an uplink TTI) may not be indexed. In some cases, a set of one or more transmissions may be referred to as a transmission occasion and may be associated with a respective transmission occasion index and a corresponding frequency hop.

In a third example, the UE may bundle (e.g., maintain phase continuity for) one or more repetitions of the uplink channel transmission in a first bundle interval, but may not bundle one or more other repetitions of the uplink channel transmission in the same bundle interval, for example, based on one or more phase continuity rules (e.g., a time between repetitions). In such cases, the UE may switch frequency resources (e.g., frequency hops) each time phase discontinuity is experienced (e.g., within a bundle interval or when switching between bundle intervals, or both).

Particular aspects of the subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages. The techniques employed by the described communication devices may provide benefits and enhancements to the operation of the communication devices, including increased channel demodulation, communication quality, and reduced overhead. For example, operations performed by the described communication devices may provide improvements to channel estimation and demodulation procedures by bundling DMRS across multiple TTIs and/or by performing frequency hopping when bundling DMRS. Bundling DMRS may improve channel estimation and demodulation procedures by increasing an accuracy of channel estimation and demodulation based on a shared, coherent parameter (e.g., phase continuity) across the bundled DMRS.

By transmitting a first repetition of an uplink channel in a first bundle interval and transmitting a second repetition of the uplink channel in a second bundle interval based on a respective starting time of the second bundle interval (e.g., using one or more bundling rules or techniques described herein), channel demodulation may be performed with increased accuracy across multiple TTIs, which may increase communication quality and thereby generally reduce communication overhead. For example, configuration of bundle intervals with respective starting times corresponding to a respective starting time of a respective available transmission time interval that occurs after an end of a respective preceding bundle interval of the plurality of bundle intervals may allow for efficient identification of resources for repetitions of the uplink channel while channel demodulation to be performed with increased accuracy within a respective bundle interval (e.g., based on defining the bundle interval according to a starting time and ending time that supports increased accuracy).

Additionally or alternatively, by transmitting a first repetition of an uplink channel in a first bundle interval and at a first frequency hop (e.g., using one or rules or techniques described herein, based on a transmission occasion index), and transmitting a second repetition of the uplink channel in a second bundle interval and at the first frequency hop or a second frequency hop (e.g., using one or more rules or techniques described herein, based on a transmission occasion index), channel demodulation may also be performed with increased accuracy across multiple TTIs, which may increase communication quality and thereby generally reduce communication overhead. For example, based on using the respective frequency hops associated with the bundle intervals for transmission of the corresponding repetition(s) of the uplink channel, channel demodulation may be performed with increased accuracy within a respective bundle interval (e.g., based using a respective frequency hop that supports increased accuracy for a corresponding bundle interval).

Based on the increased communication quality and decreased communication overhead, a wireless device may generally consume less power when communicating and may generally experience lower latency. Similarly, based on the increased accuracy of channel estimation and demodulation, uplink communications may generally experience increased reliability.

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by and described with reference to bundling schemes, a process flow, apparatus diagrams, system diagrams, and flowcharts that relate to DMRS bundling and frequency hopping.

A UE115may apply phase continuity to uplink transmissions within a bundle interval, for example, to support joint channel estimation at a base station105. In a first example, a UE115may determine bundle intervals for an uplink channel transmission based on a TTI format pattern and a bundle size. For example, bundle intervals may start on a next available uplink TTI after an end of a preceding bundle interval or that includes at least one additional uplink TTI over which transmission of multiple repetitions of the uplink channel meets one or more conditions for maintaining phase continuity after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. In a second example, the UE115may use frequency resources (e.g., a frequency hop) for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval or an index of a transmission occasion for one or more repetitions. In a third example, the UE115may not bundle some repetitions of the uplink channel transmission in a same bundle interval, for example, based on one or more phase continuity rules (e.g., a time between repetitions over which the UE115is capable of maintaining phase continuity). In such cases, the UE115may switch frequency resources (e.g., frequency hops) each time phase discontinuity is experienced (e.g., within a bundle interval or when switching between bundle intervals, or both)

FIG.2illustrates an example of a bundling scheme200in accordance with aspects of the present disclosure. The bundling scheme200may illustrate one or more techniques for enhancing or increasing coverage for uplink shared channel transmissions (e.g., transmissions on a physical uplink shared channel (PUSCH)), for uplink control channel transmissions (e.g., transmissions on a physical uplink control channel (PUCCH)), or both.

For example, some channels may experience lower transmission rates or other communication quality bottlenecks. Such channels may include channels in a frequency range 1 (FR1) such as a PUSCH for eMBB (e.g., for FDD or for TDD with “DDDSU,” “DDDSUDDSUU,” or “DDDDDDDSUU” formats), a PUSCH for voice over IP (VoIP) (e.g., for FDD or for TDD with “DDDSU” or “DDDSUDDSUU” formats), a PUCCH format 3 with 11 bits, or a PUCCH format 3 with 22 bits, among other examples. Such channels may additionally, or alternatively, include channels in a frequency range 2 (FR2) (e.g., urban 28 GHz) such as a PUSCH for eMBB (e.g., for TDD with “DDDSU” or “DDSU” formats), a PUSCH for VoIP (e.g., for TDD with “DDDSU” or “DDSU” formats), a PUCCH format 3 with 11 bits, or a PUCCH format 3 with 22 bits, among other examples. As described herein, a “D” may represent a TTI configured for downlink transmissions in a TDD format (e.g., unpaired spectrum operation), a “U” may represent an TTI configured for downlink transmissions in the TDD format, and an “S” may represent a flexible TTI in the TDD format (e.g., a TTI configured for downlink, uplink, or both).

As described herein, a flexible TTI (e.g., slot) may have a dynamic slot indication, for indicating whether the flexible TTI is associated with uplink, downlink, or both. The indication may be a slot format indication (SFI) in a downlink control information (DCI) (e.g., DCI format 2_0), where the SFI may indicate a format for the flexible TTI. TDD format (e.g., unpaired spectrum operation), as described herein, may be an example of or represent a TDD TTI format pattern, which may include a pattern of “D,” “U,” and “S,” TTIs for TDD transmissions.

In order to enhance or increase coverage for uplink shared channel and/or uplink control channel transmissions, a PUSCH repetition type (e.g., a type A) may have an increased number of repetitions (e.g., maximum number of repetitions) of a PUSCH transmission, where the number of repetitions may be counted on a basis of available uplink slots (e.g., based on a TDD TTI format). Signaling may also be configured to support PUSCH repetitions (e.g., Type A PUSCH repetitions) for a random access message 3 (msg3). Additionally, or alternatively, coverage may be increased by supporting transport block (TB) processing over a multi-slot PUSCH transmission, where a TB size (TBS) may be determined based on the multiple slots and may be transmitted over the multiple slots.

In some cases, in order to increase coverage, joint channel estimation may be performed over multiple PUSCH transmissions, for example, based on conditions for maintaining power consistency and phase continuity. The joint channel estimation may include optimization for DMRS location and/or granularity, and may additionally, or alternatively, include inter-slot frequency hopping with inter-slot bundling (e.g., DMRS bundling) to support the joint channel estimation. In some cases, in order to increase coverage, signaling may be configured to support a dynamic PUCCH repetition factor indication and/or DMRS bundling may be supported across PUCCH repetitions (e.g., repetitions of a PUCCH transmission).

When performing joint channel estimation, such as illustrated by bundling scheme202, a receiving device (e.g., a base station105) may jointly process DMRS in multiple uplink transmissions (e.g., multiple PUSCH or multiple PUCCH transmissions). For example, DMRS from multiple PUSCH transmissions may be jointly processed, or DMRS from multiple PUCCH transmissions may be jointly processed, but no joint processing may be performed for DMRS from PUSCH transmissions and DMRS from PUCCH transmissions. Each transmission may be received in a corresponding slot or TTI, where each TTI may include 14 symbols (e.g., numbered 0 to 13 inFIG.2). A transmitting device (e.g., a UE115) may maintain phase continuity across the multiple uplink transmissions (e.g., multiple PUSCH or multiple PUCCH transmissions). Maintaining phase continuity may include maintaining one or more conditions for the multiple uplink transmissions, such as maintaining a same frequency resource allocation (e.g., a same resource block (RB)), a same transmit power, a same spatial transmit relation, same antenna ports (e.g., for DMRS), and a same precoding (e.g., for DMRS).

Joint channel estimation across multiple repetitions of an uplink transmission (e.g., across multiple slots or TTIs) may increase an accuracy of the channel estimation, which may result in increased communication quality, for example, compared to other schemes, such as bundling scheme201, that support channel estimation using one slot or TTI. In such cases, the joint channel estimation may take place across multiple consecutive or non-consecutive transmissions (e.g., consecutive or non-consecutive TTIs), such that each TTI illustrated by bundling scheme202may be consecutive or non-consecutive.

FIG.3illustrates an example of a bundling scheme300in accordance with aspects of the present disclosure. The bundling scheme300may support DMRS bundling for joint channel estimation, for example, as described with reference toFIG.2. The bundling scheme300may illustrate a number of slots or TTIs (e.g., numbered from 0 to 24) over which a UE115may transmit repetitions of an uplink channel (e.g., a PUSCH or a PUCCH transmission), where the UE115may represent a UE115described with reference toFIGS.1and2. A TTI labeled “D” may represent a TTI configured for downlink transmissions, a TTI labeled “U” may represent a TTI configured for uplink transmissions, and a TTI labeled “S” may represent a flexible TTI configured for uplink transmissions, downlink transmissions, or both.

The bundling scheme300may represent a TDD format “DDDSUDDSUU” (e.g., a TTI format pattern of repeating downlink, uplink, and flexible TTIs on a same carrier, following a “DDDSUDDSUU” pattern). It is to be understood that while a “DDDSUDDSUU” format is described herein, the same examples may apply to other TDD formats (e.g., TTI format patterns) or other transmission formats (e.g., FDD formats, paired spectrum operation) without departing from the scope of the present disclosure.

A bundle interval as described herein may be defined such that the UE115may coherently transmit in the uplink subject to one or more phase continuity conditions. In some cases, a bundle interval may also be referred to as a bundle, for example, as illustrated inFIG.3. All bundle intervals may have a same bundle size (e.g., K), which may be counted as a number of consecutive slots or TTIs from a starting time of the bundle interval. The bundle size may be configured to the UE115(e.g., via RRC signaling or dynamically via DCI), or may be implicitly determined by the UE115based on the repetitions of the uplink channel transmission. For example, the UE115may determine the bundle size based on a number of repetitions of the uplink channel transmission (e.g., using a formula or equation that includes the number of repetitions as a variable).

A bundle size (e.g., K) may, in some examples, include four TTIs or eight TTIs, for example, as illustrated by the different bundle configurations (e.g., K equal to four and K equal to eight) inFIG.3. Additionally, or alternatively, a bundle size may include any number of TTIs without departing from the scope of the present disclosure. In some cases, a larger K value may result in more uplink transmission TTIs within a bundle interval (e.g., “U” TTIs), and may also result in a higher challenge to maintain phase continuity across the uplink transmissions within the bundle interval, such that determination of the bundle size K may be based on one or both of these factors.

In some cases, phase continuity may not be maintained across uplink transmissions within the bundles or bundle intervals, for example, based on one or more phase continuity rules (e.g., based on a larger bundle size). In such cases, a bundle or a bundle interval may still be defined and used as a time period or duration to perform UE operations, such as adjusting frequency before a next uplink channel transmission (e.g., among other examples).

FIG.3may illustrate an example of a baseline bundle interval design, where bundle intervals may be arranged without any time gap between consecutive bundle intervals (e.g., back-to-back). In such cases, some bundles (e.g., bundle 4 when K is equal to four) may not include any TTI for an uplink transmission (e.g., may not include a slot or TTI configured as a “U” TTI), which may impact frequency hopping across bundle intervals.

FIG.4illustrates an example of a wireless communications system400in accordance with aspects of the present disclosure. In some examples, wireless communications system400may implement some aspects of wireless communications system100. In some examples, wireless communications system400may additionally, or alternatively, implement some aspects of bundling scheme200or300. For example, wireless communications system400may include a base station105-aand a UE115-a, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-3. As described herein, UE115-amay perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions of an uplink channel transmission to base station105-a.

As described herein, transmitting repetitions of an uplink channel transmission may include transmitting an uplink message, which may be a PUSCH or PUCCH transmission, on each of the repetitions, where each uplink message may include a same TB or may include up to a number of different TBs per repetition. Each uplink message (e.g., repetition of the uplink channel transmission) may be transmitted via a respective TTI.

UE115-amay receive control signaling405(e.g., RRC signaling) from base station105-a, which may configure UE115-awith a TDD (e.g., unpaired spectrum operation) TTI format pattern (e.g., a TDD pattern of repeating “D,” “S,” and/or “U” TTIs). UE115-amay also receive a control message410(e.g., signaled via RRC or DCI) from base station105-a, which may schedule transmission of the uplink channel transmission and which may indicate for UE115-ato transmit multiple repetitions of the uplink channel transmission (e.g., may indicate a number of repetitions). In some cases, the control message410(e.g., a DCI carrying an SFI) may configure UE115-awith a TDD TTI format pattern (e.g., a TDD pattern of repeating “D,” “S,” and/or “U” TTIs).

As described with reference toFIG.3, UE115-amay be configured with or determine a bundle size for bundle intervals that each include one or more bundled repetitions of the uplink channel transmission. For example, UE115-amay receive control signaling405(e.g., RRC signaling) or the control message410(e.g., a DCI) indicating the bundle size, or UE115-amay determine the bundle size based on a number of repetitions of the uplink channel transmission indicated by the control message410. In some cases, some bundle intervals may not include any uplink TTIs (e.g., based on the TDD TTI format pattern) and the UE may be unable to apply DMRS bundling (e.g., maintain phase continuity) in such bundle intervals. Additionally, or alternatively, a bundle interval may include one or more uplink TTIs that may not support phase continuity for repetitions of the uplink channel transmission (e.g., based on one or more phase continuity rules, such as a time between repetitions based on a larger bundle interval).

The present disclosure provides techniques for applying phase continuity to uplink transmissions within a bundle interval, where UE115-amay be configured to identify a bundle interval and/or bundle interval parameters associated with the phase continuity (e.g., DMRS bundling). In a first example, UE115-amay determine bundle intervals for the uplink channel transmission based on the TDD TTI format pattern and the bundle interval size. For example, a first bundle interval may start from a first available uplink TTI (e.g., an uplink TTI or a flexible TTI configured or available for uplink transmissions) scheduled for transmission of the uplink channel transmission or from a first uplink TTI scheduled for transmission of the uplink channel transmission that meets one or more conditions for maintaining phase continuity. Because, in some cases, the first available uplink TTI may be a flexible TTI (e.g., based on an indication in SFI), in such cases, a bundle interval configuration or format may be based on an SFI indicating a format of the flexible TTI.

The first bundle interval may, for example, include a transmission (e.g., from UE115-ato base station105-a) of a first repetition415or a second repetition420of the uplink channel transmission. In some cases, the following bundle intervals may start on a first available uplink TTI (e.g., an uplink TTI or a flexible TTI configured for uplink transmissions) after an end of a preceding bundle interval, such that each bundle interval may include at least one uplink TTI. For example, UE115-amay transmit a second repetition420of the uplink channel transmission (e.g., to base station105-a) in an uplink TTI of the second bundle interval. Additionally, or alternatively, UE115-amay transmit the second repetition420of the uplink channel transmission (e.g., to base station105-a) in an uplink TTI of the first bundle interval, after the first repetition415and having phase continuity with the first repetition415(e.g., based on being transmitted in the same bundle interval).

In some cases, the following bundle intervals may start on a next available uplink TTI having a repetition420that meets the one or more conditions for phase continuity with another repetition420, after an end of a preceding bundle interval. For example, UE115-amay transmit a first repetition415of the uplink channel transmission without phase continuity and may transmit a second repetition420of the uplink channel transmission (e.g., to base station105-a) in an uplink TTI of a first bundle interval.

In a second example, UE115-amay use frequency resources (e.g., a frequency hop) for repetitions of the uplink channel transmission within a bundle interval based on an index of the bundle interval or an index of a transmission occasion for one or more of the repetitions. A set of one or more transmissions (e.g., consecutive transmissions) may be referred to as a transmission occasion and may be associated with a respective transmission occasion index and a corresponding frequency hop. In some cases, all repetitions transmitted in a first bundle interval or first transmission occasion may use frequency resources (e.g., a first frequency hop) associated with the index of the first bundle interval or the first transmission occasion, respectively. Similarly, all repetitions transmitted in a second bundle interval or second transmission occasion may use frequency resources (e.g., a second frequency hop) associated with the index of the second bundle interval or the second transmission occasion, respectively.

For example, UE115-amay transmit the first repetition415and the second repetition420(e.g., to base station105-a) within the first bundle interval, or the first transmission occasion, and using the first frequency hop. In another example, UE115-amay transmit the first repetition415(e.g., to base station105-a) within the first bundle interval, or the first transmission occasion, using the first frequency hop, and may transmit the second repetition420within the second bundle interval, or the second transmission occasion, using the second frequency hop. In some cases, all bundle intervals may be associated with consecutive indexes (e.g., whether or not a bundle interval includes an uplink TTI), or bundle intervals including an uplink TTI (e.g., an uplink TTI or a flexible TTI configured for uplink transmissions) may be associated with consecutive indexes, while other bundle intervals (e.g., not including an uplink TTI) may not be indexed. All transmission occasions may be associated with consecutive indexes (e.g., because each transmission occasion may include at least one uplink TTI).

In a third example, UE115-amay bundle (e.g., maintain phase continuity for) one or more repetitions of the uplink channel transmission in a first bundle interval, but may not bundle one or more other repetitions of the uplink channel transmission in the same bundle interval, for example, based on one or more phase continuity rules (e.g., a time between repetitions). In such cases, UE115-amay switch frequency resources (e.g., frequency hops) each time phase discontinuity is experienced (e.g., within a bundle interval or when switching between bundle intervals, or both). For example, UE115-amay transmit the first repetition415and the second repetition420in the first bundle interval, but without phase continuity. In this example, the first repetition415may be transmitted at a first frequency hop and the second repetition420may be transmitted at a second frequency hop (e.g., based on being transmitted without phase continuity).

FIG.5illustrates an example of a bundling scheme500in accordance with aspects of the present disclosure. In some examples, bundling scheme500may implement or be implemented by some aspects of wireless communications system100or400. In some examples, bundling scheme500may additionally, or alternatively, implement or be implemented by some aspects of bundling scheme200or300. For example, bundling scheme500may be implemented by a base station105and a UE115, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-4. As described herein, the UE115may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions of an uplink channel transmission to the base station105.

FIG.5illustrates a number of TTIs505(e.g., a slot or mini-slot) for transmission of the repetitions of the uplink channel transmission. The TTIs505may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern510, which may be configured by the base station105and which may indicate a pattern of downlink (“D”), uplink (“U”), and flexible (“S”) TTIs505. WhileFIG.5illustrates a “DDDSUDDSUU” TDD TTI format pattern, it is to be understood that the same examples described with reference toFIG.5may apply to other TDD formats (e.g., TTI format patterns) or other transmission formats (e.g., FDD formats, paired spectrum operation) without departing from the scope of the present disclosure. A bundle, which may also be referred to as a bundle interval520, may be used for transmitting a set of repetitions515of the uplink channel transmission with phase continuity. A bundle interval may begin at a starting time and may be defined by a number of consecutive TTIs505(e.g., a bundle size) beginning at the starting time.

In some cases (e.g., as described with reference toFIGS.3and4), a bundle interval may not line up or include a TTI505that is available for uplink transmissions (e.g., Bundle 4), for example, based on a baseline bundling scheme. Accordingly, as described with reference toFIG.4, a start of a bundle interval520(e.g., a bundle interval k+1) may be a start of a first available uplink TTI505for repetitions515of the uplink channel transmission (e.g., a PUSCH or PUCCH transmission) after an end of a preceding (e.g., immediately preceding) bundle interval520(e.g., a bundle interval k), such as after an end of a last available TTI505of a preceding bundle interval520. Additionally, or alternatively, a start of a bundle interval520(e.g., bundle interval k+1) may be a start of a first flexible TTI505(e.g., “S” slot) eligible for repetitions of the uplink channel transmission after an end of a preceding (e.g., immediately preceding) bundle interval520(e.g., bundle interval k). A first bundle interval520(e.g., Bundle 0, or a bundle interval k=0, such as for a first repetition of the uplink channel transmission) may start from a first available uplink TTI505or flexible TTI505(e.g., TTI 4) scheduled for transmission of a first or initial repetition of the uplink channel transmission. Such techniques for determining starting positions for a bundle interval520may be indicated by the base station105or may be configured at the UE115(e.g., based on a wireless communications standard).

FIG.5illustrates starting positions for bundle intervals520based on different bundle sizes (e.g., K values), where a bundle size may be configured by the network or determined implicitly, as described herein. For example,FIG.5illustrates starting positions for bundle intervals520using a K value of four and a K value of eight. A K value of four may result in bundle intervals520beginning at TTI 4, TTI 8, TTI 14, TTI 18, and TTI 24 (e.g., compared to the baseline bundle intervals, which start at TTI 4, TTI 8, TTI 12, TTI 16, TTI 20, and TTI 24 as shown inFIG.3). A K value of eight may result in bundle intervals520beginning at TTI 4, TTI 14, and TTI 24 (e.g., compared to the baseline bundle intervals, which start at TTI 4, TTI 8, TTI 12, TTI 16, TTI 20, and TTI 24). WhileFIG.5illustrates a K value of four and a K value of eight, it is to be understood that the same examples described herein with reference toFIG.5may apply to other K values without departing from the scope of the present disclosure.

FIG.6illustrates an example of a bundling scheme600in accordance with aspects of the present disclosure. In some examples, bundling scheme600may implement or be implemented by some aspects of wireless communications system100or400. In some examples, bundling scheme600may additionally, or alternatively, implement or be implemented by some aspects of bundling scheme200or300. For example, bundling scheme600may be implemented by a base station105and a UE115, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-5. As described herein, the UE115may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions of an uplink channel transmission to the base station105.

FIG.6illustrates a number of TTIs605(e.g., a slot or mini-slot) for transmission of the repetitions of the uplink channel transmission. The TTIs605may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern610as described herein, which may represent a “DDDSUDDSUU” TDD TTI format pattern. It is to be understood that the same examples described with reference toFIG.6may apply to other TDD formats (e.g., TDD TTI format patterns) or other transmission formats (e.g., FDD formats, paired spectrum operation) without departing from the scope of the present disclosure. A bundle, which may also be referred to as a bundle interval620, may be used for transmitting a set of repetitions615of the uplink channel transmission with phase continuity. A bundle interval620may begin at a starting time and may be defined by a number of consecutive TTIs605(e.g., a bundle size) beginning at the starting time. As described herein, a first bundle interval620(e.g., Bundle 0) may start from a first available uplink TTI605(e.g., TTI 4) or flexible TTI605scheduled for transmission of a first or initial repetition615of the uplink channel transmission.

In some cases, a baseline bundle interval scheme may be adopted, and as described with reference toFIGS.3and4, some bundle intervals620(e.g., Bundle 4) may not have any uplink TTIs605(e.g., or flexible TTIs useable for an uplink transmission) for transmission of the repetitions615of the uplink channel transmission. As such, frequency hopping (e.g., changing transmission frequency resources or frequency location) may fail to occur within bundle intervals620that do not include uplink TTIs605. As described herein, frequency hopping may include changing a frequency location of a repetition of the uplink channel transmission (e.g., changing to a different RB), such that phase continuity may not be maintained after frequency hopping (e.g., based on transmitting using a different frequency allocation).

In cases where a bundle interval620does not include any uplink TTIs605(e.g., or flexible TTIs605for an uplink transmission), the UE115may determine a frequency hop625(e.g., frequency locations or resources) for each repetition615of the uplink channel transmission based on an index of a corresponding bundle interval620. The index may be different from an actual bundle number (e.g., different from Bundle 0, Bundle 1, etc.). For example, the UE115may transmit corresponding repetitions615of the uplink channel transmission at a frequency hop 1 (e.g., a first frequency resource, or first RB) for even bundle intervals620(e.g., bundle intervals620with an even-numbered index). Similarly, the UE115may transmit corresponding repetitions615of the uplink channel transmission at a frequency hop 2 (e.g., a second frequency resource, or second RB) for odd bundle intervals620(e.g., bundle intervals620with an odd-numbered index).

The UE115may receive signaling from the base station105indicating frequency hop 1 and frequency hop 2, among other examples. For example, the UE115may receive (e.g., via one or more DCI parameters) an indication of a starting value (e.g., frequency value) of frequency hop 1 and an offset between frequency hop 1 and frequency hop 2. In another example, the UE115may receive an indication of a starting value (e.g., frequency value) of frequency hop 1 and a starting value (e.g., frequency value) of frequency hop 2.

In a first example (e.g., as illustrated by Option 1), the counting of bundle intervals620(e.g., bundle interval indexes) may be based on bundle intervals that have at least one uplink or flexible TTI605for transmission of a repetition615of the uplink channel transmission. Accordingly, in Option 1, Bundle 0 may be associated with an index 0, Bundle 1 may be associated with an index 1, and so on through Bundle 3 (e.g., because each of these bundles may include at least one uplink or flexible TTI605for transmission of a repetition615of the uplink channel transmission). In Option 1, Bundle 4 may not be associated with a corresponding index, for example, because Bundle 4 may not include at least one uplink or flexible TTI605for transmission of a repetition615of the uplink channel transmission. Accordingly, Bundle 5 (e.g., following Bundle 4) may be associated with an index 4. The UE115may transmit repetitions615of the uplink channel transmission at a frequency hop625corresponding to the bundle interval index. For example, uplink repetition 0 may be transmitted at frequency hop 1, uplink repetitions 1 and 2 may be transmitted at frequency hop 2, uplink repetition 3 may be transmitted at frequency hop 1, uplink repetitions 4 and 5 may be transmitted at frequency hop 2, and uplink repetition 6 (e.g., in Bundle 5) may be transmitted at frequency hop 1 (e.g., corresponding to index 4, or an even index).

In a second example (e.g., as illustrated by Option 2), the counting of bundle intervals620(e.g., bundle interval indexes) may be based on all bundle intervals620regardless of whether a bundle interval620has an uplink or flexible TTI605for transmission of a repetition615of the uplink channel transmission. Accordingly, Bundle 0 may be associated with an index 0, Bundle 1 may be associated with an index 1, and so on through Bundle 5 (e.g., or further), even though Bundle 4 may not include at least one uplink or flexible TTI605for transmission of a repetition615of the uplink channel transmission. The UE115may transmit repetitions615of the uplink channel transmission at a frequency hop625corresponding to the bundle interval index. For example, uplink repetition 0 may be transmitted at frequency hop 1, uplink repetitions 1 and 2 may be transmitted at frequency hop 2, and so forth. In this example, Bundle 5 may be associated with an index 5, such that uplink repetitions 4 and 5 (e.g., in Bundle 3) may be transmitted at frequency hop 2 and uplink repetition 6 (e.g., in Bundle 5) may also be transmitted at frequency hop 2 (e.g., associated with index 5, or an odd index).

FIG.7illustrates an example of a bundling scheme700in accordance with aspects of the present disclosure. In some examples, bundling scheme700may implement or be implemented by some aspects of wireless communications system100or400. In some examples, bundling scheme700may additionally, or alternatively, implement or be implemented by some aspects of bundling scheme200or300. For example, bundling scheme700may be implemented by a base station105and a UE115, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-6. As described herein, the UE115may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions of an uplink channel transmission to the base station105.

FIG.7illustrates a number of TTIs705(e.g., a slot or mini-slot) for transmission of the repetitions of the uplink channel transmission. The TTIs705may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern710as described herein, which may represent a “DDDSUDDSUU” TDD TTI format pattern. It is to be understood that the same examples described with reference toFIG.7may apply to other TDD formats (e.g., TTI format patterns) or other transmission formats (e.g., FDD formats, paired spectrum operation) without departing from the scope of the present disclosure. A bundle, which may also be referred to as a bundle interval720, may be used for transmitting a set of repetitions715of the uplink channel transmission with or without phase continuity. A bundle interval720may begin at a starting time and may be defined by a number of consecutive TTIs705(e.g., a bundle size) beginning at the starting time. As described herein, a first bundle interval720(e.g., Bundle 0) may start from a first available uplink TTI705(e.g., TTI 4) or flexible TTI705scheduled for transmission of a first or initial repetition715of the uplink channel transmission.

In some cases, a baseline bundle interval scheme may be adopted, and as described with reference toFIGS.3and4, some repetitions715of the uplink channel transmission in a bundle interval720(e.g., Bundle 0) may be bundled together while some repetitions715of the uplink channel transmission in the same bundle interval720may not be bundled, for example, due to one or more phase continuity rules. For example, in Bundle 0, repetition 0 may not be bundled with either of repetition 1 or repetition 2 (e.g., based on the one or more phase continuity rules), while repetitions 1 and 2 may be bundled. In one example, repetitions 1 and 2 may be too far apart (e.g., in time) from repetition 0 to maintain phase continuity (e.g., based on the one or more phase continuity rules where a UE is capable of maintaining for repetitions that are separated in time by less than a defined time interval or in frequency by less than a defined frequency range), although other examples of phase continuity rules may apply to the same or a similar example of phase discontinuity within a bundle interval720.

In cases where some repetitions715of the uplink channel transmission in a bundle interval720may not be bundled, frequency hopping may or may not be supported within the bundle interval720. In a first example (e.g., Option 1), the UE115may determine the frequency hops725for the repetitions715of the uplink channel transmission within a bundle interval720such that all repetitions715in a same bundle interval720may use a same frequency hop725. For example, the UE115may transmit all repetitions715of the uplink channel transmission within Bundle 0 at a frequency hop 1 (e.g., a first frequency resource, or first RB). The UE115may similarly transmit all repetitions715of the uplink channel transmission in Bundle 1 at a frequency hop 2 (e.g., a second frequency resource, or second RB).

In a second example (e.g., Option 2), the UE115may determine the frequency hops725for the repetitions715of the uplink channel transmission within a bundle interval720such that repetitions715of the uplink channel transmission with phase continuity (e.g., bundled repetitions715) use a same frequency hop725, while repetitions715of the uplink channel transmission without phase continuity (e.g., repetitions715that are not bundled) use different frequency hops725. For example, the UE115may transmit repetition 0 at frequency hop 1 and repetitions 1 and 2 at frequency hop 2. Determination of a frequency hop725for a first repetition715of the uplink channel transmission in a next bundle interval720may depend on a frequency hop725of a last repetition715in the preceding bundle interval720(e.g., may be a different frequency hop725than the last repetition715). For example, the UE115may transmit repetitions 1 and 2 at frequency hop 2 (e.g., in Bundle 0) and may transmit repetition 3 at frequency hop 1 (e.g., in Bundle 1) based on changing or switching bundle intervals720.

The UE115may receive signaling from the base station105indicating frequency hop 1 and frequency hop 2, among other examples. For example, the UE115may receive (e.g., via one or more DCI parameters) an indication of a starting value (e.g., frequency value) of frequency hop 1 and an offset between frequency hop 1 and frequency hop 2. In another example, the UE115may receive an indication of a starting value (e.g., frequency value) of frequency hop 1 and a starting value (e.g., frequency value) of frequency hop 2.

FIG.8illustrates an example of a bundling scheme800in accordance with aspects of the present disclosure. In some examples, bundling scheme800may implement or be implemented by some aspects of wireless communications system100or400. In some examples, bundling scheme800may additionally, or alternatively, implement or be implemented by some aspects of bundling scheme200or300. For example, bundling scheme800may be implemented by a base station105and a UE115, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-7. As described herein, the UE115may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions815of an uplink channel transmission to the base station105.

FIG.8illustrates a number of TTIs805(e.g., a slot or mini-slot) for transmission of the repetitions815of the uplink channel transmission. The TTIs805may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern810as described herein, which may represent a “DDDSUDDSUU” TDD TTI format pattern. It is to be understood that the same examples described with reference toFIG.8may apply to other TDD formats (e.g., TDD TTI format patterns) or other transmission formats (e.g., FDD formats, paired spectrum operation) without departing from the scope of the present disclosure. A bundle, which may also be referred to as a bundle interval820, may be used for transmitting a set of repetitions815of the uplink channel transmission with phase continuity. A bundle interval820may begin at a starting time and may be defined by a number of consecutive TTIs805(e.g., a bundle size) beginning at the starting time. As described herein, a first bundle interval820(e.g., Bundle 0) may start from a first available uplink TTI805(e.g., TTI 4) or flexible TTI805scheduled for transmission of a first or initial repetition815of the uplink channel transmission that meets one or more phase continuity conditions.

For example, a bundle interval820may include two or more uplink TTIs805that are available for transmission of the repetitions815of the uplink channel transmission, where the two or more uplink TTIs805include repetitions815of the uplink channel transmission that satisfy the one or more phase continuity conditions. The phase continuity condition(s) may include maintaining a modulation order between repetitions815in the two or more uplink TTIs805, maintaining a same RB allocation (e.g., a length and frequency position) between the repetitions815in the two or more uplink TTIs805, maintaining a same beam between the repetitions815in the two or more uplink TTIs805(e.g., no beam switching occurs, such as for FR2), maintaining a same transmission power level for the repetitions815in the two or more uplink TTIs805, or any combination thereof.

In some cases, the phase continuity condition(s) may include a condition that the two or more uplink TTIs805and corresponding repetitions815be consecutive. In some cases, the phase continuity condition(s) may include a condition that the repetitions815have a non-zero time gap between the repetitions815, where a downlink reception is not scheduled in the non-zero time gap. In some cases, maintaining a same transmission power level may be applied to a component carrier (CC), such that no change in power control parameters occurs. Similarly, maintaining a same transmission power level may be applied to a CC that is not impacted by one or more other concurrent CCs that are configured for inter-band carrier aggregation or dual connectivity for a same UE115with dynamic power sharing, such that there may be no change in transmission power level for any configured CC(s) that are part of configured intra-band carrier aggregation or dual connectivity. Further, the one or more phase continuity conditions may indicate that intra-TTI and inter-TTI frequency hopping is not supported within a bundle interval820.

In some cases, a baseline bundle interval scheme may be adopted (e.g., K=4 and bundle intervals820are immediately consecutive), and as described with reference toFIGS.3and4, some bundle intervals820(e.g., Bundle 4) may not have any uplink TTIs805(e.g., or flexible TTIs useable for an uplink transmission) for transmission of the repetitions815of the uplink channel transmission. In some cases, another bundle interval scheme may be adopted (e.g., K=4 and bundle intervals820include one or more uplink or flexible TTIs805), as described with reference toFIG.6. In such cases, some bundle intervals820(e.g., Bundles 0, 3) may not have any uplink TTIs805(e.g., or flexible TTIs useable for an uplink transmission) that have a repetition815that satisfies the one or more conditions for phase continuity.

In such cases, an nth window (e.g., nth bundle interval820) may start from a first available TTI805(e.g., uplink TTI805or flexible TTI805) for transmission of the uplink channel transmission, for example, after an (n−1)th window (e.g., bundle interval820). The first available repetition815may be bundled with subsequent repetitions815of the uplink channel transmission within the nth window (e.g., within the bundle interval820), for example, based on satisfying the one or more phase continuity conditions for bundling. For example, a first bundle interval820(e.g., Bundle 0) may start at TTI 8, and may continue through TTI 11, based on Bundle 0 including TTIs 8 and 9, which may both be configured for a transmission of the uplink channel transmission where transmissions of the uplink channel transmission in TTIs 8 and 9 satisfy the one or more phase continuity conditions. Bundling (e.g., applying a bundle interval820) may skip TTIs 4 and 14, which include repetitions815that may not satisfy the one or more phase continuity conditions with at least one other TTI805. A second bundle interval820(e.g., Bundle 1) may start at TTI 18, and may continue through TTI 21, based on Bundle 1 including TTIs 18 and 19, which may both be configured for transmission of the uplink channel transmission, where TTIs 18 and 19 include repetitions815that satisfy the one or more phase continuity conditions.

FIG.9illustrates an example of a bundling scheme900in accordance with aspects of the present disclosure. In some examples, bundling scheme900may implement or be implemented by some aspects of wireless communications system100or400. In some examples, bundling scheme900may additionally, or alternatively, implement or be implemented by some aspects of bundling scheme200or300. For example, bundling scheme900may be implemented by a base station105and a UE115, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-7. As described herein, the UE115may perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions915of an uplink channel transmission to the base station105.

FIG.9illustrates a number of TTIs905(e.g., a slot or mini-slot) for transmission of the repetitions915of the uplink channel transmission. The TTIs905may be associated with a TDD (e.g., unpaired spectrum operation) TTI format pattern910as described herein, which may represent a “DDDSUDDSUU” TDD TTI format pattern. It is to be understood that the same examples described with reference toFIG.9may apply to other TDD formats (e.g., TDD TTI format patterns) or other transmission formats (e.g., FDD formats, paired spectrum operation) without departing from the scope of the present disclosure. A bundle, which may also be referred to as a bundle interval920, may be used for transmitting a set of repetitions915of the uplink channel transmission with phase continuity. A bundle interval920may begin at a starting time and may be defined by a number of consecutive TTIs905(e.g., a bundle size) beginning at the starting time. As described herein, a first bundle interval920(e.g., Bundle 0) may start from a first available uplink TTI905(e.g., TTI 4) or flexible TTI905scheduled for transmission of a first or initial repetition915of the uplink channel transmission that meets one or more phase continuity conditions, for example, as described with reference toFIG.8. For example, a first bundle interval920(e.g., Bundle 0) may begin at TTI 8, based on Bundle 0 including TTIs 8 and 9 (e.g., that satisfy the one or more phase continuity rules). Similarly, a second bundle interval (e.g., Bundle 1) may begin at TTI 18, based on Bundle 1 including TTIs 18 and 19 (e.g., that satisfy the one or more phase continuity rules).

In such cases, frequency hops925for repetitions915of the uplink channel may be determined based on an index of an associated transmission occasion930(e.g., may be independent of bundling). For example, one or more transmission occasions930may be defined, where each transmission occasion930may have a corresponding index. Each repetition915of the uplink channel in a bundle interval920may belong to a same transmission occasion930, while each repetition915of the uplink channel outside of a bundle interval920may have its own transmission occasion930. For example, a first transmission occasion930(e.g., TO 0) may include a first repetition915in TTI 4, where the first repetition915may not be bundled with any other repetitions915(e.g., may be outside of a bundle interval920). The first repetition915of the first transmission occasion930may, for example, fail to satisfy one or more phase continuity conditions for bundling (e.g., within a bundle interval920) because the first repetition915may be scheduled for transmission in TTI905that is outside of a threshold number of TTIs905from another repetition915(e.g., if a bundle interval920were to include the first repetition915, the first repetition915would be the only repetition915within the bundle interval920).

A second transmission occasion930(e.g., TO 1) may include second and third repetitions915in TTIs 8 and 9, respectively, where the second and third repetitions915may be bundled together in Bundle 0. For example, TTIs 8 and 9 (e.g., for transmission of the second and third repetitions915) may include repetitions915that satisfy one or more phase continuity conditions (e.g., may be consecutive transmissions), and therefore the second and third repetitions915may be bundled together in Bundle 0 (e.g., a first bundle interval920).

A frequency hop925for each repetition may be based on a corresponding transmission occasion index. For example, frequency hop 1 may apply to all even indexes and frequency hop 2 may apply to all odd indexes, or vice versa. In such cases, frequency hop 1 may apply to 0 (e.g., an even or zero index) and the corresponding first repetition915and frequency hop 2 may apply to 1 (e.g., an odd index) and the corresponding second and third repetitions915. Similarly, frequency hop 1 may apply to 2 and TO 4, and frequency hop 2 may apply to 3.

FIG.10illustrates an example of a process flow1000in accordance with aspects of the present disclosure. In some examples, process flow1000may implement or be implemented by some aspects of wireless communications system100or400. In some examples, process flow1000may additionally, or alternatively, implement or be implemented by some aspects of bundling schemes200,300,500,600, or700. For example, process flow1000may be implemented by a base station105-band a UE115-b, which may represent respective examples of a base station105and a UE115described with reference toFIGS.1-7. As described herein, UE115-bmay perform bundling (e.g., DMRS bundling, such as by maintaining phase continuity) for one or more sets of repetitions of an uplink channel transmission to base station105-b.

In the following description of process flow1000, the operations may be performed in a different order than the order shown, or the operations performed by UE115-band base station105-bmay be performed in different orders or at different times. For example, specific operations may also be left out of process flow1000, or other operations may be added to process flow1000. Although UE115-band base station105-bare shown performing the operations of process flow1000, some aspects of some operations may also be performed by one or more other wireless devices.

At1005, in some cases, base station105-bmay transmit, to UE115-b, control signaling, such as RRC signaling. The control signaling may indicate a TDD (e.g., unpaired spectrum operation) TTI format pattern or other TTI format as described herein, which UE115-band base station105-bmay use for one or more downlink and/or uplink transmissions (e.g., repetitions of the uplink channel transmission). The TDD TTI format pattern may indicate a pattern of one or more uplink TTIs, one or more downlink TTIs, one or more flexible TTIs, or any combination thereof, over multiple TTIs.

In some cases, the control signaling may define a bundle size applicable to a set of multiple bundle intervals. As described herein, the bundle size may define each bundle interval by a number of consecutive TTIs following a starting time of the respective bundle interval. In some cases, the control signaling may indicate a bundle interval configuration that indicates each bundle interval of a set of multiple bundle intervals includes at least one uplink TTI, at least one flexible TTI, or both. In some cases, the control signaling may indicate a bundle interval configuration that indicates each bundle interval of a set of multiple bundle intervals includes at least one uplink TTI, at least one flexible TTI, or both, for repetitions of the uplink channel that satisfy one or more phase continuity conditions.

At1010, base station105-bmay transmit, to UE115-b, a control message configuring UE115-bto transmit multiple repetitions of an uplink channel transmission (e.g., an uplink channel, such as a PUSCH or PUCCH). In some cases, the control message may indicate or define the bundle size as described herein. The control message may indicate a number of the multiple repetitions, and in some cases, UE115-bmay use the indicated number of repetitions to determine the bundle size (e.g., based on an equation). In some cases, the control message may include an indication of a value of a first frequency hop and an offset, where a second frequency hop may be based on the first frequency hop and the offset. In some other cases, the control message may include an indication of a value of a first frequency hop and a value of a second frequency hop.

At1015, UE115-bmay transmit, to base station105-b, a first repetition of the multiple repetitions of the uplink channel transmission in a first available TTI of a first bundle interval of the set of bundle intervals. In some cases, a starting time of the first bundle interval may be a first TTI available for transmission of an uplink channel repetition or a first TTI available for transmission of an uplink channel repetition that satisfies the one or more phase continuity conditions. In some cases, the TDD TTI format pattern may indicate that the starting time of the first bundle interval is a flexible TTI that is useable as an uplink TTI. UE115-bmay transmit the first repetition at a first frequency hop (e.g., a first frequency location or resource, such as an RB) of a set of multiple frequency hops. In some cases, the first frequency hop may correspond to a first index of the first bundle interval or a first transmission occasion as described herein.

At1020, in some cases, UE115-bmay transmit, to base station105-b, a third repetition of the multiple repetitions of the uplink channel transmission. The third repetition may be transmitted in the first bundle interval and may have phase continuity with the first repetition, for example, based on being transmitted in a same bundle interval. In some cases, the third repetition may be transmitted at the first frequency hop (e.g., based on an index of the first bundle interval or first transmission occasion, based on having phase continuity with the first repetition, or both).

At1025, UE115-bmay transmit, to base station105-b, a second repetition of the multiple repetitions of the uplink channel transmission. In some cases, UE115-bmay transmit the second repetition in the first bundle interval. In some other cases, UE115-bmay transmit the second repetition in a first available TTI of a second bundle interval of the set of bundle intervals. As described herein, a starting time of the second bundle interval may be a next TTI available for transmission of an uplink channel repetition that occurs after an end of a preceding bundle interval of the set of bundle intervals or a next TTI available for transmissions of repetitions of an uplink channel repetition that satisfies the one or more phase continuity conditions, that occurs after an end of a preceding bundle interval of the set of bundle intervals. In some cases, the TDD TTI format pattern may indicate that the starting time of the second bundle interval is a flexible TTI that is useable as an uplink TTI (e.g., is an available TTI). UE115-bmay transmit the second repetition at a second frequency hop (e.g., a second frequency location or resource, such as an RB) of the set of frequency hops.

In a first example, UE115-bmay transmit the second repetition in the second bundle interval at the second frequency hop, where the second frequency hop may correspond to a second index of the second bundle interval or a second transmission occasion as described herein. Consecutive indexes of the bundle intervals may correspond to bundle intervals having an available (e.g., uplink or flexible) TTI in the TDD TTI format pattern or may correspond to each consecutive bundle interval (e.g., with or without an available uplink TTI).

In a second example, UE115-bmay transmit the second repetition in the first bundle interval at the second frequency hop, where the second repetition may not have phase continuity with the first repetition. For example, UE115-bmay transmit the second repetition without phase continuity with the first repetition based on one or more phase continuity rules not being satisfied.

At1030, in some cases, UE115-bmay transmit, to base station105-b, a fourth repetition of the multiple repetitions of the uplink channel transmission. The fourth transmission may be transmitted in the second bundle interval. In some cases, the fourth repetition may have phase continuity with the second repetition (e.g., based on being transmitted in a same bundle interval). In some cases, the fourth repetition may be transmitted at the second frequency hop (e.g., based on an index of the second bundle interval or the second transmission occasion). In some cases, the fourth repetition may be transmitted at the first frequency hop (e.g., based on being transmitted after a preceding repetition at the second hop and in a different bundle interval or transmission occasion).

The receiver1110may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to DMRS bundling and frequency hopping). Information may be passed on to other components of the device1105. The receiver1110may utilize a single antenna or a set of multiple antennas.

The communications manager1120, the receiver1110, the transmitter1115, or various combinations thereof or various components thereof may be examples of means for performing various aspects of DMRS bundling and frequency hopping as described herein. For example, the communications manager1120, the receiver1110, the transmitter1115, or various combinations or components thereof may support a method for performing one or more of the functions described herein.

In some examples, the communications manager1120may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the receiver1110, the transmitter1115, or both. For example, the communications manager1120may receive information from the receiver1110, send information to the transmitter1115, or be integrated in combination with the receiver1110, the transmitter1115, or both to receive information, transmit information, or perform various other operations as described herein.

The communications manager1120may support wireless communication at a UE in accordance with examples as disclosed herein. For example, the communications manager1120may be configured as or otherwise support a means for receiving, from a base station, a control message configuring the UE to transmit a set of multiple repetitions of an uplink channel. The communications manager1120may be configured as or otherwise support a means for transmitting a first repetition of the set of multiple repetitions of the uplink channel in a first available TTI of a first bundle interval of a set of multiple bundle intervals. The communications manager1120may be configured as or otherwise support a means for transmitting a second repetition of the set of multiple repetitions of the uplink channel in a second available TTI of a second bundle interval of the set of multiple bundle intervals, each bundle interval of the set of multiple bundle intervals having a respective starting time corresponding to a respective starting time of a respective available TTI that occurs after an end of a respective preceding bundle interval of the set of multiple bundle intervals.

Additionally, or alternatively, the communications manager1120may support wireless communication at a UE in accordance with examples as disclosed herein. For example, the communications manager1120may be configured as or otherwise support a means for receiving, from a base station, a control message configuring the UE to transmit a set of multiple repetitions of an uplink channel. The communications manager1120may be configured as or otherwise support a means for transmitting a first repetition of the set of multiple repetitions of the uplink channel in a first bundle interval of a set of multiple bundle intervals and at a first frequency hop of a set of multiple frequency hops, the first frequency hop corresponding to a first index of the first bundle interval.

The communications manager1120may be configured as or otherwise support a means for transmitting a first repetition of the set of multiple repetitions of the uplink channel via a first transmission occasion, in a first bundle interval of a set of multiple bundle intervals, and at a first frequency hop of a set of multiple frequency hops based on a first transmission occasion index of the first transmission occasion. The communications manager1120may be configured as or otherwise support a means for transmitting a second repetition of the set of multiple repetitions of the uplink channel via a second transmission occasion, in a second bundle interval of the set of multiple bundle intervals, and at the first frequency hop or a second frequency hop of the set of multiple frequency hops based on a second transmission occasion index of the second transmission occasion.

The communications manager1120may be configured as or otherwise support a means for transmitting, in the first bundle interval at a second frequency hop of the set of multiple frequency hops, a second repetition of the set of multiple repetitions of the uplink channel that does not have phase continuity with the first repetition.

The actions performed by the communications manager1120, among other examples herein, may be implemented to realize one or more potential advantages. For example, communications manager1120may increase available battery power and communication quality at a wireless device (e.g., a UE115) by bundling repetitions of an uplink channel transmission and/or using frequency hopping for transmission of one or more of the repetitions. The increase in communication quality may result in increased link performance and decreased overhead based on bundling repetitions of an uplink channel transmission and/or using frequency hopping for transmission of one or more of the repetitions. Accordingly, communications manager1120may save power and increase battery life at a wireless device (e.g., a UE115) by strategically increasing a quality of communications at a wireless device (e.g., a UE115).

The receiver1210may provide a means for receiving information such as packets, user data, control information, or any combination thereof associated with various information channels (e.g., control channels, data channels, information channels related to DMRS bundling and frequency hopping). Information may be passed on to other components of the device1205. The receiver1210may utilize a single antenna or a set of multiple antennas.

The transmitter1215may provide a means for transmitting signals generated by other components of the device1205.

In some examples, the transmitter1215may be co-located with a receiver1210in a transceiver module. The transmitter1215may utilize a single antenna or a set of multiple antennas.

The device1205, or various components thereof, may be an example of means for performing various aspects of DMRS bundling and frequency hopping as described herein. For example, the communications manager1220may include a control reception component1225, an uplink channel transmission component1230, an uplink channel bundling component1235, or any combination thereof.
