WINDOW CONFIGURATION FOR CELLULAR DISCONTINUOUS COMMUNICATIONS

Methods, systems, and devices for wireless communication are described that provide for aligning a starting time of a cell-based discontinuous transmission (DTX) and/or discontinuous reception (DRX) mode between a network entity and one or more user equipment (UE) within the serving cell associated with the network entity. The aligning may be accomplished via coordinated signaling. For example, the network may configure a periodic interval for transmitting information related to a discontinuous operation mode in group common downlink control information (GC DCI) messages. In some additional examples, the periodic interval may allow for beam sweeping of the GC DCI messages and efficient cell-based activation or deactivation of the discontinuous operation mode.

FIELD OF TECHNOLOGY

The following relates to wireless communication, including a window configuration for cellular discontinuous communications.

BACKGROUND

A network entity in a serving cell may employ a discontinuous transmission (DTX) mode, a discontinuous reception (DRX) mode, or both, for power savings. The DTX mode and the DRX mode may include a time duration during which the network entity limits transmissions to one or more UEs in the serving cell or limits receptions from the one or more UEs in the serving cell, respectively. In some cases, the network entity does not transmit any transmissions during the DTX mode and does not receive any transmissions in the DRX mode.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support a window configuration for cellular (e.g., cellular, serving cell-based) discontinuous communications. For example, the described techniques provide for aligning a starting time of a cell-based discontinuous transmission (DTX) and/or discontinuous reception (DRX) mode between a network entity and one or more user equipment (UEs) within a serving cell associated with the network entity. The aligning may be accomplished via coordinated signaling. For example, the network may configure a periodic interval for transmitting information related to cell-based discontinuous communications in group common downlink control information (GC DCI) messages. In some additional or alternative examples, the periodic interval may allow for beam sweeping of the GC DCI messages and efficient cell-based activation or deactivation of the cell-based discontinuous operation mode.

DETAILED DESCRIPTION

A network entity may employ cell-based discontinuous operation, including a cell-based discontinuous transmission (DTX) mode and a cell-based discontinuous reception (DRX) mode, or both, to increase power savings and improve overall device coordination and efficiency in a wireless communications system. For example, cell-based DTX and DRX communications may decrease network power consumption and decrease overall resource utilization by allowing the network entity (and corresponding user equipment (UE)) to periodically enter a sleep state during a set of configured “off” durations (e.g., non-active periods) of a DTX or DRX cycle. For example, a DTX off duration may be a duration of the DTX cycle in which the network entity does not transmit signaling, and a DRX off duration may be a duration of the DRX cycle in which the network device does not receive signaling. In contrast, a DTX “on” duration (e.g., active period) may be a duration of the DTX cycle in which the network entity transmits signaling, and a DRX on duration may be a duration of the DRX cycle in which the network entity receives signaling.

To notify one or more UEs in a serving cell associated with the network entity about upcoming cell-based DTX or DRX communication modes, the network entity may transmit control signaling (e.g., control information, control messaging) to the one or more UEs via a group common downlink control information (GC DCI) message format, which utilizes a common scheduling for the DTX or DRX communications for the one or more UEs. In some cases, however, the one or more UEs may not know when the network entity transmits the GC DCI, and the one or more UEs may not know when an on duration of the cell-based DTX or DRX begins. In such cases, the one or more UEs may potentially mis-detect the GC DCI and may wake up during an off duration, leading to power loss as the one or more UEs monitor for the GC DCI (e.g., or other DTX communications) during the configured off duration.

Techniques described herein provide for aligning a starting time of a cell-based discontinuous operational mode, including DTX and DRX modes, between a network entity and one or more UEs within a serving cell associated with the network entity. The aligning may be accomplished via coordinated signaling. For example, the network entity may configure a periodic interval for communicating information related to the discontinuous operational mode. The periodic interval may include a monitoring window in which the one or more UEs may expect to receive at least one instance of a GC DCI message, a duration for performing discontinuous operational mode communications, and one or more offsets or delay durations. More specifically, the network entity may configure an initial delay associated with the periodic interval, and a starting offset of a periodic interval (e.g., a chronologically or temporally first periodic interval) relative to a system frame number boundary. The network entity may also configure the monitoring window, during which the one or more UEs may monitor for one or more instances of the GC DCI message. The network entity may also configure an application delay that the one or more UEs may use to switch between a UE DTX mode and a UE DRX mode, or return to a sleep state for power savings. The network entity may also configure the monitoring window to repeat according to a periodicity. In some additional examples, the monitoring window may allow for beam sweeping of the GC DCI message and efficient cell-based activation or deactivation of the discontinuous operational mode.

Aspects of the disclosure are initially described in the context of wireless communications systems and signaling diagrams. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to window configuration for cellular discontinuous communications.

The UEs115and the network entities105may support retransmissions of data to increase the likelihood that data is received successfully. Hybrid automatic repeat request (HARQ) feedback is one technique for increasing the likelihood that data is received correctly via a communication link (e.g., a communication link125, a D2D communication link135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific slot for data received via a previous symbol in the slot. In some other examples, the device may provide HARQ feedback in a subsequent slot, or according to some other time interval. In some cases, HARQ feedback corresponding to GC DCIs may not be supported by the UEs115or the network entities105, thus, techniques to configure and align a starting time for cell-based DTX and DRX modes may be used to increase signaling reliability for the UEs115and network entities105.

Techniques described herein provide for aligning a starting time of a cell-based discontinuous communications, including cell-based DTX and DRX modes, between a network entity and one or more UEs115within a serving cell associated with a network entity105. The aligning of the starting time may be accomplished via coordinated signaling. For example, the network entity105may configure a periodic interval for communicating information related to the discontinuous operation mode. The periodic interval may include (at least) a monitoring window in which the one or more UEs115may expect to receive at least one instance of a GC DCI message, a duration for performing discontinuous communications, and one or more offsets or delay durations. More specifically, the network entity105may configure an initial delay associated with the periodic interval, and a starting offset of a periodic interval relative to a system frame number boundary. The network entity105may also configure the monitoring window, during which the one or more UEs115may monitor for one or more instances of the GC DCI message. The network entity105may also configure an application delay that the one or more UEs115may use to switch between a UE DTX mode and a UE DRX mode, or return to a sleep state or other low power mode for power savings. The network entity105may also configure the monitoring window to repeat according to a periodicity. In some additional or alternative examples, the monitoring window may allow for beam sweeping of the GC DCI message and efficient cell-based activation or deactivation of the discontinuous operational mode.

FIG.2shows an example of a wireless communications system200that supports window configuration for cellular discontinuous communications in accordance with one or more aspects of the present disclosure. Wireless communications system200may implement or be implemented by aspects of wireless communications system100. For example, the wireless communications system200may include a network entity105-aand UEs115(e.g., UE115-aand UE115-b), each of which may be examples of network entities105and UEs115as described with reference toFIG.1. Although a quantity of UEs115and network entities105are depicted in the wireless communications system200, the techniques described herein may support different quantities of UEs115and network entities105within the wireless communications system200.

In the wireless communications system200, the network entity105-amay transmit information (e.g., signaling, messages, transmissions) to the UEs115. For example, the network entity105-amay transmit control information (e.g., control information210-aand control information210-b), GC DCI messaging (e.g., GC DCI messaging215-aand GC DCI messaging215-b), and discontinuous communications (e.g., discontinuous communications220-aand discontinuous communications220-b) to the UEs115. In some cases, the network entity105-amay transmit the information via broadcasting methods (e.g., multicast methods) to the UEs115. Additionally or alternatively, the network entity105-amay transmit the information to the UE115-aand to the UE115-bvia a downlink channel205-aand a downlink channel205-b, respectively.

In some examples, UEs115may transmit information to the network entity105-a. For example, the UEs115may transmit capability messaging and discontinuous communications (e.g., discontinuous communications220-cand discontinuous communications220-d) to the network entity105-a. The UE115-aand the UE115-bmay transmit the information to the network entity via an uplink channel225-aand an uplink channel225-b, respectively.

In some wireless communications systems such as the wireless communications system200, GC DCI signaling may suffer from reduced communications reliability, especially in the case of indicating cell-based discontinuous operational information via the GC DCI signaling. For example, communicating HARQ feedback associated with the GC DCI signaling may not be supported by the UEs115, the network entity105-a, or both. Additionally or alternatively, in some cases, the UEs115may mis-detect (e.g., incorrectly decode, fail to detect altogether) a GC DCI message from the network entity105-acontaining information related to cell-based discontinuous operation.

In such cases, reduced reliability and misdetection of the GC DCI may negatively impact the wireless communications system200. In one example, one or more of the UEs115may perform operations (e.g., loop operations, CSI, beam management (BM), radio link monitoring (RLM), radio resource management (RRM)) while downlink signaling is turned off during a cell-based DTX off duration. In another example, the UEs115may waste power monitoring a physical downlink control channel (PDCCH) while the network entity105-ais not transmitting via the PDCCH during a cell-based DTX off duration. In some other examples, the UE115may transmit sounding reference signal (SRS) or physical random access channel (PRACH) during a cell-based DRX off duration. Each of these examples may waste wireless communications resources and increase power consumption at the UEs115and the network entity105-a.

Aspects of the present disclosure are related to aligning a starting time of a discontinuous communications window between the UEs115and the network entity105-aso that the UEs115may receive GC DCI messaging from the network entity105-aand perform discontinuous communications with the network entity105-a. Such alignment of the starting time eliminates association of GC DCI monitoring messages and the cell-based discontinuous communications with arbitrary slots, which increases coordination within the network since aligning multiple starting times for the cell-based discontinuous communications among different UEs would require a relatively greater amount of resources and energy.

According to aspects presented herein, and to reduce negative impacts on the wireless communications system200, a starting time of cell-based discontinuous communications may be aligned between the UEs115and the network entity105-a. The starting time of cell-based discontinuous communications may be associated with the reception time of a GC DCI message carrying information associated with cell-based discontinuous communications at the UEs115. Additionally, or alternatively, the starting time may be associated with an application time (e.g., a duration for applying changes) based on the information associated with cell-based discontinuous communications. For example, the starting time may allow sufficient time for the UEs115to adjust reception operations, transmission operations, or both, (or switch between reception operations and transmission operations) based on the information associated with the cell-based discontinuous communications.

Accordingly, the network entity105-amay transmit information associated with cell-based discontinuous communications to the UEs115. For example, the control information210-aand the control information210-bmay indicate a periodic interval and a monitoring window within the periodic interval. The monitoring window may be for the monitoring or receipt of the GC DCI messaging215-aand the GC DCI messaging215-b. In some cases, the GC DCI messaging may contain information associated with the cell-based discontinuous communications.

The network entity105-aand the UEs115may transmit discontinuous communications to each other based on the information associated with cell-based discontinuous communications. For example, the network entity105-aand the UEs115may transmit or receive the discontinuous communications during a DTX on duration or a DRX on duration, respectively. In some cases, this may increase the reliability and overall resource utilization in GC DCI signaling.

FIG.3shows an example of a signaling diagram300that supports window configuration for cellular discontinuous communications in accordance with one or more aspects of the present disclosure. The signaling diagram300may implement or be implemented by aspects ofFIGS.1and2. For example, the signaling diagram300may depict periodic intervals305(e.g., periodic interval305-aand periodic interval305-b) described with reference toFIG.2, and may be implemented at or by the devices described with reference toFIGS.1and2. Although exemplary quantities of durations, periods, or messages are depicted in the signaling diagram300, it is noted that this disclosure may be generalized to include any quantity of such durations, periods, and messages.

The signaling diagram300may depict the periodic intervals305indicated by the network entity105ofFIG.2. The periodic intervals305may contain initial delays310, application delays315(e.g., application delay315-a), and monitoring windows320(e.g., monitoring window320-aand monitoring window320-b). The monitoring windows320may be for a network entity to transmit and a UE to receive at least one instance of a GC DCI message325(e.g., GC DCI message325-aand GC DCI message325-b). The initial delays310and the application delays315may be for the UEs115and the network entity105to implement any changes to internal configurations (e.g., receiver configurations, transmitter configurations).

A network entity may transmit an indication of a configuration of cell-based discontinuous communications to one or more UEs. For example, the configuration may include parameters, where some or all of the parameters may correspond to or configure some or all aspects of the signaling diagram300. For example, the parameters may include an initiation interval configuration that may indicate a period (e.g., duration, recurring duration) of the periodic intervals305. The initiation interval configuration may indicate the period of the periodic intervals305as a quantity of slots, symbols, TTIs, or other units time or resources. Additionally or alternatively, the initiation interval configuration may indicate a starting offset340of one or more periodic intervals (e.g., an initial or chronologically first periodic interval, periodic interval305-a) relative to a radio frame boundary (e.g., an SFN frame boundary).

The parameters of the configuration of cell-based discontinuous communications may include a monitoring window configuration (e.g., GC DCI monitoring window configuration). The monitoring window configuration may indicate a duration of the monitoring windows320. In some cases, the monitoring window configuration may indicate the duration of the monitoring windows320as a quantity of slots, symbols, TTIs, or other units of time or resources. The monitoring window configuration may also indicate one or more monitoring occasions (e.g., PDCCH monitoring occasions, time resources, frequency resources) within the monitoring windows320, where the one or more monitoring occasions may be for the network entity to transmit and for one or more UEs to receive one or more instances of a GC DCI message325. The monitoring window configuration may also indicate the initial delays310before the monitoring windows320within the periodic intervals305. For example, the monitoring window configuration may indicate a duration of the initial delays310as a quantity of slots, symbols, TTIs, or other units of time or resources.

The parameters of the configuration of cell-based discontinuous communications may include an application delay configuration, corresponding to the application delays315. The application delay315may be a duration between a last symbol of a monitoring occasion carrying an instance of the GC DCI message and a starting slot of a next periodic interval. For example, the application delay315-amay be the duration between the last symbol of the PDCCH carrying GC DCI message325-band the starting slot of periodic interval305-b.

The network entity may utilize the application indication delay configuration to ensure that the application delays315are greater than or equal to a threshold quantity of symbols (e.g., OFDM symbols). In some cases, the threshold quantity of symbols may be specified (e.g., preconfigured at the network entity, preconfigured at the UE) per subcarrier spacing of associated PDCCH symbols. Additionally or alternatively, the threshold quantity of symbols may be a value (e.g., a maximum value) among a set of values reported in a UE capability report. For example, each of the UEs may report a value corresponding to a smallest quantity of symbols in which the UE is capable of applying changes for the discontinuous operational mode indicated by a GC DCI message325. In such examples, the network entity may select the largest of the values reported by the UEs as the threshold quantity of symbols for the application delays315so that the UEs have sufficient time to adapt their operation in response to the indication by a GC DCI message. Additionally or alternatively, the threshold quantity of symbols may be dependent on whether the GC DCI message is indicative of a cell-based DTX mode or a cell-based DRX mode, and may be dependent on whether the GC DCI message is activating or deactivating cell-based discontinuous communications.

The network entity may transmit one or more GC DCI messages within each of the monitoring windows320. For example, the network entity105may transmit GC DCI message325-aand GC DCI message325-bwithin the monitoring window320-a. The GC DCI message325-aand the GC DCI message325-bmay be instances of a first GC DCI message. Stated differently, the GC DCI messages325in a monitoring window, such as the monitoring window320-a, may all carry the same contents (e.g., content of the DCI messages). The monitoring window320-bmay contain a same or different quantity of GC DCI messages325as the monitoring window320-a. Additionally, the GC DCI messages325of the monitoring window320-bmay be instances of a second GC DCI message, where the first GC DCI message and the second GC DCI message may carry the same or different contents. Although a quantity of GC DCI messages325are depicted herein, it is noted that this disclosure may be extended to include any quantity of GC DCI messages325within each monitoring window320.

The GC DCI messages325may indicate information associated with cell-based discontinuous communications. For example, the GC DCI messages325of the monitoring window320-amay include an indication of an activation or a deactivation (e.g., an activation status or deactivation status) of cell-based discontinuous communications. The indication of the activation or the deactivation of cell-based discontinuous communications may be associated with (e.g., take effect at) a starting candidate position (e.g., a starting candidate position330-a, a starting candidate position330-b, and a starting candidate position330-c) of a next periodic interval. For example, an indication of an activation of cell-based discontinuous communications received in the monitoring window320-amay indicate that cell-based discontinuous communications will activate at the starting candidate position330-b.

In some examples, the UEs may monitor all or part of the monitoring windows320. For example, a UE may monitor the monitoring window320-auntil a time335, at which point the UE may receive (e.g., decode, detect) the GC DCI message325-a. In some examples, the UE may refrain from monitoring for the rest of the GC DCI messages325(e.g., other PDCCH monitoring occasions) within the monitoring window320-aafter the time335based on having received the GC DCI message325. In some other examples, the UE may continue to monitor for the rest of the GC DCI messages325within the monitoring window320-aafter the time335.

According to some aspects of the disclosure, a network entity may transmit more than one GC DCI message in the monitoring windows320to lower a probability of a UE mis-detecting a GC DCI message325, as discussed herein. In some cases, the network entity may decide or configure a quantity of PDCCH monitoring occasions and corresponding GC DCI messages325that are configured and transmitted within each monitoring window320.

In some cases, a UE may monitor all serving cells communicating with the UE for the GC DCI messages325during the monitoring windows320. In some other cases, a UE may monitor specific serving cells for the GC DCI messages during the monitoring windows320. For example, the UE may monitor a primary serving cell, a special serving cell (e.g., a primary serving cell and a combination of the primary serving cell and a secondary serving cell), or both, for the GC DCI messages325during the monitoring windows320.

Additionally or alternatively, the GC DCI messages325may carry other information associated with window configuration for cellular discontinuous communications. For example, the GC DCI messages325may indicate a common flag that indicates an activation or deactivation of the discontinuous operational mode for a quantity of serving cells. For example, of a set of serving cells, a subset of the serving cells may correspond to the common flag. The subset of serving cells may be configured by the network entity (e.g., a lead network entity, the network entity transmitting the GC DCI messages325), and the configuration may be performed or indicated via RRC signaling.

In some examples, the network entity may transmit a GC DCI message325comprising the common flag, which may indicate an activation or deactivation of the discontinuous communications for the subset of serving cells. At a starting candidate position, each serving cell in the subset of serving cells may activate or deactivate the discontinuous communications within the respective serving cell, according to the activation or deactivation indicated by the common flag.

The discontinuous communications may include cell-based discontinuous operational modes, including a DTX mode, a DRX mode, or both, which may be configured jointly or separately. If the DTX mode and the DRX mode are configured separately, the indication of activation or deactivation of the discontinuous operational mode may comprise two bits, such that one bit indicates activation or deactivation for the DTX mode, and the other bit indicates activation or deactivation for the DRX mode. In some other examples, if the DTX mode and the DRX mode are configured jointly, the indication of activation or deactivation of the discontinuous operational mode may comprise one common bit, where the one common bit indicates activation or deactivation of both the DTX mode and the DRX mode. In some cases, the one common bit may provide for lower DCI overhead compared to other options.

FIG.4shows an example of a signaling diagram400that supports window configuration for cellular discontinuous communications in accordance with one or more aspects of the present disclosure. The signaling diagram400may implement or be implemented by aspectsFIGS.1-3. For example, the signaling diagram400may include a network entity105-b, which may be an example of network entities105and network entity105-aofFIGS.1and2, respectively. The signaling diagram may also include a periodic interval405comprising an initial delay410, application delays415, monitoring windows (e.g., monitoring window420), GC DCI messages425(e.g., GC DCI message425-a, GC DCI message425-b, GC DCI message425-c, GC DCI message425-d, GC DCI message425-e, and GC DCI message425-f), and a starting candidate position430, which may correspond to respective aspects ofFIG.3. Although exemplary quantities of durations, periods, or messaging are depicted in the signaling diagram400, this disclosure may be generalized or extended to include any quantity of such durations, periods, and messaging.

The signaling diagram400illustrates the network entity105-btransmitting multiple GC DCI messages425via multiple transmit beams435. The multiple transmit beams435may be associated with a beam sweeping procedure. In some systems, beam sweeping for GC DCI messaging may increase the reliability of delivery for the GC DCI messages425.

In some cases, each transmit beam435may correspond to (e.g., be used to transmit) one or more GC DCI messages425transmitted in the monitoring window420. For example, the transmit beam435-amay correspond to the GC DCI messages425-aand425-d, the transmit beam435-bmay correspond to the GC DCI messages425-band425-e, the transmit beam435-cmay correspond to the GC DCI messages425-cand425-f, and the transmit beam435-dmay correspond to one or more additional GC DCI messages. In some systems, the network entity105-bmay determine or configure the parameters or the transmit beams435, which transmit beams435to include in the beam sweeping procedure, and the quantity of GC DCI messages425to transmit via each transmit beam435during the monitoring window420. In some cases, the transmit beams435may be associated with one or more different directions, frequencies, bandwidths, or other beamforming parameters.

FIG.5shows an example of a process flow500that supports window configuration for cellular discontinuous communications in accordance with one or more aspects of the present disclosure. The process flow500may implement or be implemented by aspects ofFIGS.1-4. For example, the process flow500may include a network entity105-cand a UE115-c, which may be examples of network entities105and UEs115ofFIGS.1,2, and4. Additionally, some aspects of process flow500may be associated with or based on the discontinuous communications, the periodic intervals305, and the periodic intervals405ofFIGS.3and4.

In the following description of process flow500, the operations may be performed in a different order than the order shown, or other operations may be added or removed from the process flow500. For example, some operations may also be left out of process flow500, may be performed in different orders or at different times, or other operations may be added to process flow500. Although the UE115-cand the network entity105-care shown performing the operations of process flow500, some aspects of some operations may also be performed by one or more other wireless devices or network devices.

At505, the UE115-cmay transmit a capability report associated with GC DCI messaging to the network entity105-c. In some cases, the capability report may include one or more values, where at least one of the values corresponds to at least a smallest quantity of symbols in which the UE115-cis capable to apply changes for the discontinuous operational mode indicated by a GC DCI message. The capability report may comprise other indications of parameters of the UE115-cassociated with GC DCI messaging and discontinuous operation.

At510, the network entity105-cmay determine a threshold quantity of symbols for the duration of one or more application delays for the discontinuous operation mode window configuration. The threshold quantity of symbols may be based on the capability report received at the network entity105-cfrom UE115-cand one or more other UEs. For example, the network entity105-cmay select a largest value of the values received in the capability reports as the threshold quantity of symbols. In this way, the network entity105-cmay select a threshold quantity of symbols large enough to allow all of the UEs that transmitted a capability report to the network entity105-cto apply changes for the discontinuous operation mode within the application delay.

At515, the network entity105-cmay transmit control information to the UE115-c. The network entity105-cmay transmit the control information to the UE115-cvia a downlink control channel, or via a broadcast or multicast method. The control information may indicate a periodic interval, as well as a monitoring window, an initial delay, and an application delay within the periodic interval. The control information may further indicate one or more monitoring occasions (e.g., PDCCH monitoring occasions) within the monitoring window, where the monitoring window is for the network entity105-cto transmit GC DCI messages within the monitoring occasions and for the UE115-cto receive the GC DCI messages within the monitoring occasions.

Additionally or alternatively, the control information may indicate other aspects of the periodic interval. For example, the control information may indicate a duration for the periodic interval, a starting offset for the periodic interval (e.g., a chronologically first periodic interval) relative to a radio frame boundary, or both. The control information may also indicate a duration for the monitoring window, an initial delay for the monitoring window relative to a first symbol of the periodic interval, or both. Additionally or alternatively, the control information may indicate the application delay of the periodic interval, where the application delay may be a delay duration between a last symbol of a downlink control channel within the monitoring window and a first slot of a next periodic interval.

At520-a, the network entity105-cmay transmit one or more GC DCI messages during the monitoring window. The network entity105-cmay transmit the one or more GC DCI messages during the monitoring occasions of the monitoring window. The network entity105-cmay determine a quantity of instances of the GC DCI messages to be sent during the monitoring window, where each instance of the GC DCI message in the monitoring window carries the same information (e.g., DCI information).

The GC DCI messages may contain information related to a cell-based discontinuous operation mode for the one or more serving cells associated with the network entity105-c. For example, the GC DCI messages may contain an indication of an activation or a deactivation for cell-based discontinuous communications. The indication of the activation or the deactivation may be a common flag associate with one or more serving cells. For example, the network entity may configure a subset of serving cells from a set of serving cells, where the subset of serving cells may be associated with the common flag. The subset of serving cells may be aligned such that each serving cell of the subset of serving cells activates or deactivates the discontinuous operation mode according to the indication in the common flag.

Cell-based discontinuous communications may be associated with a DTX mode, a DRX mode, or both, which may be configured jointly or separately. The indication of the activation or the deactivation may also be associated with the DTX mode, the DRX mode, or both. In one example, if the DTX mode and the DRX mode are jointly configured, the indication of the activation or the deactivation may contain one bit. The one bit may indicate the activation or the deactivation of both the DTX mode and the DRX mode. In another example, if the DTX mode and the DRX mode are separately configured, the indication of the activation or the deactivation may contain two bits. Of the two bits, one bit may indicate the activation or the deactivation of the DTX mode, and the other bit may indicate the activation or the deactivation of the DRX mode.

The network entity105-cmay transmit the GC DCI messages as part of a beam sweeping procedure (e.g., operation). For example, one or more of the GC DCI messages may correspond to a first transmit beam, and another one or more of the GC DCI messages may correspond to a second transmit beam. The network entity105-cmay determine the quantity of transmit beams, the parameters of each transmit beam, and the quantity of DCI messages to transmit via each transmit beam of the beam sweeping procedure. The beam sweeping procedure may increase the reliability of the GC DCI messaging between the network entity105-cand the UE115-c.

At520-b, the UE115-cmay monitor for the GC DCI messages in the monitoring occasions of the monitoring window. As discussed herein, the GC DCI messages may contain information associated with cell-based discontinuous communications, such as an indication of the activation or the deactivation of the discontinuous operation mode in one or more serving cells.

The UE115-cmay monitor all or part of the monitoring windows of the discontinuous operation mode. For example, the UE115-cmay monitor a monitoring window until the UE115-creceives a GC DCI message. In some cases, the UE115-cmay refrain from monitoring for the rest (e.g., a remaining quantity) of the GC DCI messages within the monitoring window after the having received the GC DCI message. In some other cases, the UE115-cmay continue to monitor for the rest of the GC DCI messages within the monitoring window after having received the GC DCI message.

At525, the network entity105-cand the UE115-cmay communicate messages according to cell-based discontinuous communications. For example, the network entity105-cmay refrain from transmitting messages (e.g., downlink messaging) or from receiving messages (e.g., uplink messaging) during a cell-based DTX off duration or a cell-based DRX off duration, respectively. Likewise, the UE115-cmay refrain from transmitting messages (e.g., uplink messaging) or monitoring for messages (e.g., downlink messaging) during a cell based DRX off-duration or a cell-based DTX off-duration.

The at least one memory930may store computer-readable, computer-executable code935including instructions that, when executed by the at least one processor940, cause the device905to perform various functions described herein. The code935may be stored in a non-transitory computer-readable medium such as system memory or another type of memory. In some cases, the code935may not be directly executable by the at least one processor940but may cause a computer (e.g., when compiled and executed) to perform functions described herein. In some cases, the at least one memory930may contain, among other things, a basic I/O system (BIOS) which may control basic hardware or software operation such as the interaction with peripheral components or devices.

The at least one processor940may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, a CPU, a microcontroller, an ASIC, an FPGA, a programmable logic device, a discrete gate or transistor logic component, a discrete hardware component, or any combination thereof). In some cases, the at least one processor940may be configured to operate a memory array using a memory controller. In some other cases, a memory controller may be integrated into the at least one processor940. The at least one processor940may be configured to execute computer-readable instructions stored in a memory (e.g., the at least one memory930) to cause the device905to perform various functions (e.g., functions or tasks supporting window configuration for cellular discontinuous communications). For example, the device905or a component of the device905may include at least one processor940and at least one memory930coupled with or to the at least one processor940, the at least one processor940and at least one memory930configured to perform various functions described herein. In some examples, the at least one processor940may include multiple processors and the at least one memory930may include multiple memories. One or more of the multiple processors may be coupled with one or more of the multiple memories, which may, individually or collectively, be configured to perform various functions herein. In some examples, the at least one processor940may be a component of a processing system, which may refer to a system (such as a series) of machines, circuitry (including, for example, one or both of processor circuitry (which may include the at least one processor940) and memory circuitry (which may include the at least one memory930)), or components, that receives or obtains inputs and processes the inputs to produce, generate, or obtain a set of outputs.

Further, as described herein, being “configured to,” being “configurable to,” and being “operable to” may be used interchangeably and may be associated with a capability, when executing code stored in the at least one memory930or otherwise, to perform one or more of the functions described herein.

The communications manager920may support wireless communication in accordance with examples as disclosed herein. For example, the communications manager920is capable of, configured to, or operable to support a means for receiving control information that indicates a periodic interval and a monitoring window within the periodic interval, where the monitoring window is for receipt of one or more instances of a GC DCI message. The communications manager920is capable of, configured to, or operable to support a means for receiving, within the monitoring window, at least one instance of the GC DCI message in accordance with the control information, the at least one instance of the GC DCI message including a configuration for a cell-based discontinuous operation mode.

By including or configuring the communications manager920in accordance with examples as described herein, the device905may support techniques for improved communications reliability at the UE, specifically during GC DCI communications and discontinuous operation mode communications. For example, the UE may more reliably receive GC DCI messaging due to the monitoring window being aligned between the UE and the network entity. Since the GC DCI messaging contains information associated with cell-based discontinuous operation mode communications, the UE may more reliably communicate during discontinuous operation modes, leading to less latency due to mis-detecting transmissions.

In some examples, the communications manager920may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise in cooperation with the transceiver915, the one or more antennas925, or any combination thereof. Although the communications manager920is illustrated as a separate component, in some examples, one or more functions described with reference to the communications manager920may be supported by or performed by the at least one processor940, the at least one memory930, the code935, or any combination thereof. For example, the code935may include instructions executable by the at least one processor940to cause the device905to perform various aspects of window configuration for cellular discontinuous communications as described herein, or the at least one processor940and the at least one memory930may be otherwise configured to, individually or collectively, perform or support such operations.
