Patent Description:
New radio
(NR), which may also be referred to as <NUM>, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). However, as the demand for mobile broadband access continues to increase, further improvements in LTE and NR technologies remain useful. 3GPP contribution <NPL>) relates to issues of duplexing flexibility in FDD band, the need for UL/DL time offset and the characteristic, support of half duplex, SFI for FDD, and slot format indicator. 3GPP contribution <NPL>) discusses some proposals about physical structure and search space for GC PDCCH, how to indicate SFI in various condition, UE operations with GC PDCCH for GP configuration or fallback, and relationship among control signals. 3GPP contribution <NPL>) discusses the use cases and corresponding contents for GC PDCCH. <CIT>relates to techniques that provide the ability for a subframe to be dynamically configured in time division duplex (TDD) communications between a UE radio terminal and a radio network node. 3GPP contribution <NPL>) discusses issues on GC-PDCCH carrying SFI. WO <NUM>/<NUM> A1 describes methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a time division duplexing (TDD) multi-slot slot format indicator (SFI) for a set of slots. The UE may identify that the UE is operating in a frequency division duplexing (FDD) mode. The UE may determine, based on the FDD mode and the TDD multi-slot SFI, a downlink slot format and an uplink slot format for a subset of the set of slots.

Any embodiment, aspect, example or implementation not claimed, is only presented as information.

At base station <NUM>, a transmit processor <NUM> may receive data from a data source <NUM> for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs.

Controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform one or more techniques associated with slot configuration for full duplex communication, as described in more detail elsewhere herein. For example, controller/processor <NUM> of base station <NUM>, controller/processor <NUM> of UE <NUM>, and/or any other component(s) of <FIG> may perform or direct operations of, for example, process <NUM> of <FIG> and/or other processes as described herein. Memories <NUM> and <NUM> may store data and program codes for base station <NUM> and UE <NUM>, respectively. More specifically, memory <NUM> may comprise one or more instructions for wireless communication that, when executed by one or more processors of UE <NUM>, e.g., processors <NUM>, <NUM>, or <NUM>, or any combination thereof, cause and/or instruct the one or more processors to perform aspects of any of example <NUM> and/or process <NUM> with reference to <FIG>, <FIG>, <FIG>, and <FIG>. Memory <NUM> may comprise a non-transitory computer-readable medium storing the one or more instructions, or, additionally or alternatively, memory <NUM> may comprise the one or more instructions which were copied onto memory <NUM> from a non-transitory computer-readable medium storing the one or more instructions for wireless communication.

In some aspects, UE <NUM> may include means for receiving, from a BS <NUM>, information identifying a slot configuration indicating a slot format for each of a plurality of slots for a wireless communication link between UE <NUM> and the BS <NUM>, wherein the information identifying the slot configuration includes a full duplex slot format indicator that is associated with at least one full duplex slot that is to be used for full duplex communication, means for communicating, based at least in part on receiving the information identifying the slot configuration, with the BS <NUM> using the at least one full duplex slot, and/or the like. In some aspects, such means may include one or more components of UE <NUM> described in connection with <FIG>, including, for example, antennas <NUM>, modulator/demodulators <NUM>, MIMO detector <NUM>, receive processor <NUM>, controller/processor <NUM>, memory <NUM>, transmit processor <NUM>, and/or TX MIMO processor <NUM>, or any combination thereof.

An interlace structure may be used for each of the downlink and uplink for FDD in certain telecommunications systems (e.g., NR). For example, Q interlaces with indices of <NUM> through Q - <NUM> may be defined, where Q may be equal to <NUM>, <NUM>, <NUM>, <NUM>, or some other value. Each interlace may include slots that are spaced apart by Q frames. In particular, interlace q may include slots q, q + Q, q + 2Q, etc., where q ∈ {<NUM>,.

Received signal quality may be quantified by a signal-to-interference-plus-noise ratio (SINR), or a reference signal received quality (RSRQ), or some other metric.

New Radio (NR) may refer to radios configured to operate according to a new air interface (e.g., other than Orthogonal Frequency Divisional Multiple Access (OFDMA)-based air interfaces) or fixed transport layer (e.g., other than Internet Protocol (IP)). In aspects, NR may utilize OFDM with a CP (herein referred to as cyclic prefix OFDM or CP-OFDM) and/or SC-FDM on the uplink, and/or may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplexing (TDD). In aspects, NR may, for example, utilize OFDM with a CP (herein referred to as CP-OFDM) and/or discrete Fourier transform spread orthogonal frequency-division multiplexing (DFT-s-OFDM) on the uplink, and/or may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include Enhanced Mobile Broadband (eMBB) service targeting wide bandwidth (e.g., <NUM> megahertz (MHz) and beyond), millimeter wave (mmW) targeting high carrier frequency (e.g., <NUM> gigahertz (GHz)), massive MTC (mMTC) targeting nonbackward compatible MTC techniques, and/or mission critical targeting ultra reliable low latency communications (URLLC) service.

Alternatively, NR may support a different air interface, other than an OFDMbased interface.

In a wireless network, a BS may configure a UE with a slot configuration for downlink communication, uplink communication, and/or the like. However, the BS may be unable to signal, to the UE, a slot configuration that includes one or more full duplex slots that may be used for full duplex communication. Thus, even if the UE is capable of performing full duplex communication, the BS may be unable to configure a slot configuration, for a wireless communication link between the BS and the UE, that enables the UE to utilize the UE's full duplex communication capabilities. As a result, the UE may experience decreased throughput on the wireless communication link, increased latency on the wireless communication link, and/or the like.

Some aspects described herein provide techniques and apparatuses for slot configuration for full duplex communication. In some aspects, a base station may transmit, to a user equipment, information identifying a slot configuration indicating a format for each of a plurality of slots for a wireless communication link between the UE and the BS. For example, the slot configuration may indicate, for each slot, whether the each slot is an uplink slot, a downlink slot, or a full duplex slot. In a semi-static slot configuration, the slot configuration may indicate whether the each slot is an uplink slot, a downlink slot, a full duplex slot, or a flexible slot that may be dynamically configured or defined by the BS. In such a semi-static slot configuration, the format of slots indicated as uplink, downlink, or full duplex cannot be dynamically changed, however, the format of the flexible slot may be dynamically configured or defined by the BS, using an indicator/indication transmitted to the UE in a dynamic slot indication, as an uplink slot, a downlink slot or a full duplex slot. The information identifying the slot configuration may include an indication of at least one full duplex slot, included in the slot configuration, that is to be used for full duplex communication. The UE may receive the information identifying a slot configuration and may communicate, based at least in part on receiving the information identifying the slot configuration, with the base station using the at least one full duplex slot.

In this way, the slot configuration permits the UE to simultaneously perform uplink communication and downlink communication during the at least one full duplex slot. This permits the UE to transmit and receive a greater quantity of communications during the at least one full duplex slot relative to an uplink slot or a downlink slot, which increases the throughput on the wireless communication link. Moreover, this decreases the amount of time a communication waits to be transmitted or received by the UE, which decreases latency on the wireless communication link. In addition, this increases the flexibility in scheduling communications for the UE (e.g., by introducing a new full duplex slot format, such as FDX).

<FIG> are diagrams illustrating an example <NUM> of slot configuration for full duplex communication, in accordance with various aspects of the present disclosure. As shown in <FIG>, example <NUM> may include a base station (e.g., BS <NUM>) and a user equipment (UE <NUM>).

In some aspects, BS <NUM> and UE <NUM> may be included in a wireless network. BS <NUM> and UE <NUM> may be communicatively connected via a wireless communication link, which may include an uplink and a downlink. In some aspects, BS <NUM> may configure UE <NUM> with a slot configuration for communicating on the uplink, for communicating on the downlink, and/or the like.

As shown in <FIG>, to configure UE <NUM> with a slot configuration, BS <NUM> may transmit a signaling communication to UE <NUM>. The signaling communication may include a radio resource control (RRC) communication, a medium access control control element (MAC-CE) communication, a downlink control information (DCI) communication, and/or the like.

The signaling communication may include information identifying the slot configuration for the wireless communication link. In some aspects, the information identifying the slot configuration may indicate a slot format for each of a plurality of slots for the wireless communication. For example, the information identifying the slot configuration may indicate a downlink (DL) slot format for one or more downlink slots and/or symbols for downlink communication, may indicate an uplink (UL) slot format for one or more uplink slots and/or symbols for uplink communication, may indicate a flexible (FLEX or F) slot format for one or more flexible slots and/or symbols that may be dynamically configured by BS <NUM>, may indicate a full duplex (FDX) slot format for one or more full duplex slots and/or symbols for full duplex communication, and/or the like.

In some aspects, and as shown in <FIG>, the one or more downlink slots and/or symbols, included in the slot configuration, may be identified, in the signaling communication, via a downlink (DL) slot format indicator. The one or more uplink slots and/or symbols, included in the slot configuration, may be identified, in the signaling communication, via an uplink (UL) slot format indicator. The one or more flexible slots and/or symbols, included in the slot configuration, may be identified, in the signaling communication, via a flexible (FLEX or F) slot format indicator. The one or more full duplex slots and/or symbols, included in the slot configuration, may be identified, in the signaling communication, via a full duplex (FDX) slot format indicator.

In some aspects, the slot configuration may be indicated in a semi-static slot configuration (e.g., that is included in an RRC signaling communication). In some aspects, the slot configuration may be indicated in a dynamic slot indication (e.g., that is included in a MAC-CE or DCI communication). The dynamic slot indication may dynamically (e.g., periodically, aperiodically, semi-periodically, as needed or desired, and/or the like) configure one or more flexible slots and/or symbols that are identified in a semi-static slot configuration as being permitted to be dynamically configured by BS <NUM>. For example, BS <NUM> may dynamically configure a flexible slot, included in a semi-static slot configuration, as an uplink slot, a downlink slot, or a full duplex slot.

As further shown in <FIG>, and by reference number <NUM>, UE <NUM> may receive the signaling communication and may communicate with BS <NUM> based at least in part on the slot configuration identified in the signaling communication. For example, UE <NUM> may receive, from BS <NUM>, one or more downlink communications during the one or more downlink slots. As another example, UE <NUM> may transmit, to BS <NUM>, one or more uplink communications during the one or more uplink slots. As another example, UE <NUM> may transmit one or more uplink communications during the one or more full duplex slots, may receive one or more downlink communications during the one or more full duplex slots, may simultaneously transmit one or more uplink communications and receive one or more downlink communications during the one or more full duplex slots, and/or the like. In some aspects, particular uplink beams may be used on the uplink, and/or particular downlink beams may be used on the downlink, based at least in part on the isolation characteristics of the uplink beams and downlink beams, to ensure there is sufficient isolation between the uplink and the downlink for simultaneous transmission and reception by UE <NUM>.

In some aspects, UE <NUM> may be unable to simultaneously transmit an uplink communication and receive a downlink communication in a full duplex slot. For example, UE <NUM> may be unable to simultaneously transmit an uplink communication and receive a downlink communication in the full duplex slot based at least in part on a type of uplink communication to be transmitted in the full duplex slot and/or a type of downlink communication to be received in the full duplex slot, based at least in part on a quasi-co-location (QCL) relationship between the uplink communication and the downlink communication (e.g., which may indicate one or more downlink beams that are used by BS <NUM> to transmit on the downlink, may include one or more uplink beams that are used by UE <NUM> to transmit on the uplink, and/or the like), and/or the like.

In this case, UE <NUM> may apply various priority rules (e.g., which may be received from BS <NUM>, may be pre-configured for UE <NUM>, and/or the like) for determining whether to transmit the uplink communication (e.g., and drop or refrain from receiving the downlink communication) or whether to receive the uplink communication (e.g., and drop or refrain from transmitting the downlink communication) in the full duplex slot. Table <NUM> illustrates various example priority rules that UE <NUM> may apply to a full duplex slot. Other priority rules and/or priority rules that differ from the priority rules described in Table <NUM> may be used.

As illustrated in Table <NUM>, an example priority rule may include receiving a physical downlink shared channel (PDSCH) communication in the full duplex slot and dropping or refraining from transmitting a physical uplink shared channel (PUSCH) communication in the full duplex slot. Another example priority rule may include simultaneously receiving a PDSCH communication and transmitting a physical uplink control channel (PUCCH) communication in the full duplex slot. Another example priority rule may include receiving a PDSCH communication in the full duplex slot and dropping or refraining from transmitting an uplink sounding reference signal (SRS) in the full duplex slot.

Another example priority rule may include simultaneously receiving a physical uplink control channel (PUCCH) communication and transmitting a PUSCH communication in the full duplex slot. Another example priority rule may include simultaneously receiving a PUSCH communication and transmitting a PUCCH communication in the full duplex slot. Another example priority rule may include simultaneously receiving a PUSCH communication and transmitting a SRS in the full duplex slot.

Another example priority rule may include simultaneously receiving a downlink channel state information reference signal (CSI-RS) and transmitting a PUSCH communication in the full duplex slot. Another example priority rule may include simultaneously receiving a downlink CSI-RS and transmitting a PUCCH communication in the full duplex slot. Another example priority rule may include simultaneously receiving a downlink CSI-RS and transmitting a SRS in the full duplex slot.

Another example priority rule may include receiving a downlink tracking reference signal (TRS) in the full duplex slot and dropping or refraining from transmitting a PUSCH communication in the full duplex slot. Another example priority rule may include receiving a downlink TRS in the full duplex slot and dropping or refraining from transmitting a PUCCH communication in the full duplex slot. Another example priority rule may include receiving a TRS in the full duplex slot and dropping or refraining from transmitting an uplink SRS communication in the full duplex slot.

As shown in <FIG> and <FIG>, in some aspects, UE <NUM> and/or BS <NUM> may use a full duplex slot, indicated in the slot configuration, to reconfigure and/or repurpose one or more uplink slots or one or more downlink slots indicated in the slot configuration. As shown in <FIG>, and by reference number <NUM>, UE <NUM> may initiate the transmission of, and transmit, uplink data, to BS <NUM>, in a plurality of uplink slots indicated in the slot configuration. As shown by reference number <NUM>, while transmitting the uplink data, UE <NUM> may receive, in a full duplex slot indicated in the slot configuration, an indication from BS <NUM> to switch a subset of the plurality of uplink slots to downlink slots. The indication may be included in a signaling communication, such as an RRC communication, a MAC-CE communication, a DCI communication, and/or the like. As shown by reference number <NUM>, UE <NUM> may switch the subset of the plurality of slots to downlink slots and receive, from BS <NUM>, downlink data in the switched downlink slots. In this way, if BS <NUM> is to transmit downlink data, to UE <NUM>, that is urgent, high priority, and/or associated with a low latency parameter, BS <NUM> may reduce the latency of transmitting the downlink data by instructing UE <NUM> to dynamically switch the subset of the plurality of uplink slots to downlink slots so that UE <NUM> may receive the downlink data earlier in time than if UE <NUM> were to wait for a downlink slot to receive the downlink data. Means for performing the functionality of any of <NUM>, <NUM>, and/or <NUM> may, but not necessarily, include, for example, antennas <NUM>, modulator/demodulators <NUM>, MIMO detector <NUM>, receive processor <NUM>, controller/processor <NUM>, memory <NUM>, transmit processor <NUM>, and/or TX MIMO processor <NUM>, or any combination thereof.

As shown in <FIG>, and by reference number <NUM>, BS <NUM> may initiate the transmission of downlink data, to UE <NUM>, in a plurality of downlink slots indicated in the slot configuration. As shown by reference number <NUM>, while receiving the downlink data, UE <NUM> may determine to transmit uplink data to BS <NUM>. Accordingly, UE <NUM> may switch a subset of the plurality of downlink slots to uplink slots and may transmit, in a full duplex slot indicated in the slot configuration, an indication to BS <NUM> to switch the subset of the plurality of downlink slots to uplink slots. The indication may be included in a PUSCH communication, a PUCCH communication, and/or the like. As shown by reference number <NUM>, UE <NUM> may transmit, to BS <NUM>, the uplink data in the switched uplink slots. In this way, if UE <NUM> is to transmit uplink data, to BS <NUM>, that is urgent, high priority, and/or associated with a low latency parameter, UE <NUM> may reduce the latency of transmitting the uplink data by instructing BS <NUM> to dynamically switch the subset of the plurality of downlink slots to uplink slots so that UE <NUM> may transmit the uplink data earlier in time than if UE <NUM> were to wait for an uplink slot to transmit the uplink data.

In this way, BS <NUM> may transmit, to UE <NUM>, a slot configuration that includes one or more full duplex slots, which permit UE <NUM> to simultaneously perform uplink communication and downlink communication. This permits UE <NUM> to transmit and receive a greater quantity of communications during the one or more full duplex slots relative to an uplink slot or a downlink slot, which increases the throughput on the wireless communication link between BS <NUM> and UE <NUM>. Moreover, this decreases the amount of time a communication waits to be transmitted or received by UE <NUM>, which decreases latency on the wireless communication link. In addition, this increases the flexibility in scheduling communications for UE <NUM> (e.g., by introducing a new full duplex slot format).

As shown in <FIG>, process <NUM> may include receiving, from a BS, information identifying a slot configuration for a wireless communication link between the UE and the BS, wherein the information identifying the slot configuration includes a full duplex slot format indicator that is associated with at least one full duplex slot, included in the slot configuration, that is to be used for full duplex communication (block <NUM>). For example, the UE (e.g., using receive processor <NUM>, controller/processor <NUM>, memory <NUM>, and/or the like) may receive, from a BS, information identifying a slot configuration for a wireless communication link between the UE and the BS, as described above. In some aspects, the information identifying the slot configuration includes a full duplex slot format indicator that is associated with at least one full duplex slot, included in the slot configuration, that is to be used for full duplex communication.
