摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a report indicating that a cooperative reception group including the UE and one or more other UEs connected to the UE over an out-of-band link supports one or more downlink transmit beamforming techniques. The UE may determine, based at least in part on the one or more downlink transmit beamforming techniques supported by the cooperative reception group, a downlink transmit precoder associated with relaxed beamforming nulling. The UE may decode a downlink transmission received from the base station based at least in part on the downlink transmit precoder and one or more decoded bits received from the one or more other UEs in the cooperative reception group. Numerous other aspects are provided.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping. In some implementations, a user equipment (UE) may receive a discovery reference signal (DRS) including a skipping signal identifying one or more UEs, may stay on an anchor channel when the skipping signal identifies the UE, and may switch from the anchor channel to a first downlink (DL) hopping channel of a DL frequency hopping pattern when the signal does not identify the UE. In some other implementations, a base station (BS) may be configured to output a DRS including a skipping signal identifying one or more UEs, output a signal indicating a channel occupancy time (COT) obtained on a first DL hopping channel of a DL frequency hopping pattern, and output DL data on the first DL hopping channel of the DL frequency hopping pattern.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some aspects, a base station (BS) and a user equipment (UE) may communicate with one another over a sequence of unique frequency sub-bands of a frequency hopping pattern. In some instances, the BS and the UE may switch from a current frequency sub-band to another frequency sub-band based on a number of unsuccessful attempts to gain access to the current frequency sub-band. In some other instances, the BS and the UE may communicate data using configured grant (CG) resources based on a number of unsuccessful attempts to gain access to the current frequency sub-band.

摘要： A user equipment (UE) transmits, to a base station, a transmission configuration indication (TCI) report indicating associations between a plurality of TCIs and one or more UE panels of the UE; receives, from the base station in response to the TCI report, a TCI configuration message indicating a first set of TCI of the plurality of TCIs for a physical downlink control channel (PDCCH) transmission; and skips monitoring, based at least in part on the TCI configuration message, a control resource set (CORESET) associated with a second set of TCI of the plurality of TCIs.

摘要： Methods, systems, and devices for wireless communication are described. A base station may determine a configuration for UE-to-UE sharing of a channel occupancy time (COT) and may transmit the configuration to a UE to indicate that it can share a UE-acquired COT with at least another UE. A UE may acquire a COT using a listen-before-talk (LBT) procedure, and if successful, may transmit a signal indicating that the COT is being shared with at least another UE. Additionally, a UE may receive a signal from another UE indicating that it has acquired a COT in a shared spectrum and that the COT is being shared with other UEs. The UE may perform a shortened LBT procedure within the COT, and if successful, may transmit an uplink transmission in the shared spectrum.

摘要： Methods, systems, and devices for wireless communication are described. A base station may determine a configuration including a set of signature waveforms for a micro-sleep mode of operation in shared spectrum, and may transmit the configuration to at least one user equipment (UE) served by the base station. Additionally, a UE may receive a configuration including a set of signature waveforms for a micro-sleep mode of operation in shared spectrum. The UE may detect at least one signature waveform of the set of signature waveforms, and in response to detecting the at least one signature waveform, operate in the micro-sleep mode for a period of time.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on an access link from a base station, a first downlink control information (DCI) that schedules a first communication on a physical sidelink shared channel (PSSCH) and a second DCI that schedules a second communication on the PSSCH. The first communication and the second communication may be scheduled according to a rule for overlapping or ordering communications on the PSSCH that are associated with one or more hybrid automatic repeat request identifiers. The UE may transmit the first communication and the second communication as scheduled. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first sidelink user equipment (UE) may transmit, to a second sidelink UE via sidelink control information (SCI), a receiving (Rx) beam schedule indicating Rx beams associated with the first sidelink UE in a set of slots, wherein the Rx beam schedule indicates that the first sidelink UE is configured to tune to the Rx beams in the set of slots for possible sidelink receptions. The first sidelink UE may receive, from the second sidelink UE, a sidelink transmission using an Rx beam indicated in the Rx beam schedule. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a helper user equipment (UE) may receive, from a base station, a signaling message requesting the helper UE to monitor for and transmit a sidelink communication in a manner that uses a single-frequency network, wherein the sidelink communication is to be transmitted by a source UE to a destination UE that is different from the helper UE. The helper UE may receive the sidelink communication, transmitted by the source UE to the destination UE, in a first time-frequency resource of the single-frequency network. The helper UE may transmit the sidelink communication in a second time-frequency resource of the single-frequency network, wherein the second time-frequency resource is indicated to the helper UE by the base station. Numerous other aspects are described.
