摘要： Wireless communications systems and methods related to configured transmissions in a shared radio frequency band are provided. A user equipment (UE) receives, from a base station (BS), an indication of a first configured resource in a shared radio frequency band for a communication in a first direction. The UE receives, from the BS, a first configuration to select between a validation of the first direction or an absence of an invalidation of the first direction for using the first configured resource for the communication. The UE communicates, with the BS, the communication in the first direction using the first configured resource based on the first configuration.

摘要： A base station may select whether to configure one or more second RACH reference slots associated with a plurality of first RACH reference slots in a RACH configuration period. The one or more second RACH reference slots may be new RACH reference slots, and the plurality of first RACH reference slots may be previously existing RACH reference slots. The base station may identify, upon selecting to configure the one or more second RACH reference slots, a RACH reference slot configuration including the one or more second RACH reference slots associated with the plurality of first RACH reference slots in the RACH configuration period. The base station may transmit, to at least one UE, an indication of the RACH reference slot configuration including the one or more second RACH reference slots associated with the plurality of first RACH reference slots.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive multiple semi-persistent scheduling (SPS) configurations, the multiple SPS configurations including a first SPS configuration associated with a first control resource set (CORESET) group and a second SPS configuration associated with a second CORESET group. The UE may receive a downlink control information (DCI) message indicating to release one or more SPS configurations of the multiple SPS configurations. The UE may release the one or more SPS configurations in accordance with the DCI message. The UE may transmit hybrid automatic repeat request (HARQ) feedback regarding the DCI message on a selected HARQ feedback resource. Numerous other aspects are described.

摘要： Aspects described herein relate to transmitting or receiving a demodulation reference signal (DMRS) for an antenna port over a set of multiple DMRS frequency tones in a symbol of a slot based on a DMRS configuration, and transmitting or receiving a phase tracking reference signal (PTRS) for the antenna port over a cluster of multiple PTRS frequency tones in the symbol or a different symbol of the slot, wherein the cluster of multiple PTRS frequency tones are adjacent to one another in frequency, and wherein at least one PTRS frequency tone in the cluster of multiple PTRS frequency tones is a non-zero power (NZP) PTRS frequency tone that overlaps, in frequency, at least one DMRS frequency tone in the set of DMRS frequency tones.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration for a time domain (TD) control channel element (CCE) bundle that includes at least one TD CCE for single carrier waveforms, wherein a phase continuity is assumed for a duration of the TD CCE bundle. The UE may perform a channel estimation using the TD CCE bundle based at least in part on the phase continuity for the duration of the TD CCE bundle. Numerous other aspects are described.

摘要： Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions across multiple transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting, to at least one receiver UE, one or more PSSCHs in one or more of the TTIs being indicated as passing the LBT channel access procedure based on the performance.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for channel sensing with self-interference awareness for unlicensed band. A node may transmit, via a first entity of the node, at least one signal during a LBT procedure of a second entity of the node. The at least one signal may include a signal energy. The LBT procedure may be associated with a total measured interference from all detected energy sources. The node may determine a self-interference at the second entity of the node based on the signal energy of the at least one signal transmitted via the first entity of the node and calculate an interference from at least one other source based on a difference between the total measured interference from all detected energy sources and the self-interference determined based on the signal energy of the at least one signal.

摘要： This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for UL LBT status reporting. A scheduled node (e.g., a UE) may sense a status of each LBT channel in a set of one or more LBT channels. The set of one or more LBT channels may include at least one of one or more first LBT channels associated with a scheduling grant or one or more second LBT channels unassociated with the scheduling grant. The scheduled node may transmit, to a scheduling node (e.g., a base station), a LBT status report indicative of the status of each LBT channel in the set of one or more LBT channels. The scheduling node may schedule, via a second scheduling grant, a second set of one or more LBT channels based on the status of each LBT channel indicated in the LBT status report.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, a physical downlink control channel (PDCCH) that includes a grant for a communication scheduled via the PDCCH prior to a radio resource control configuration indicating a timing offset between the PDCCH and the communication scheduled via the PDCCH. The UE and/or the network node may determine a timing offset between the PDCCH and the communication scheduled via the PDCCH based at least in part on a default time domain resource assignment table for a subcarrier spacing associated with the communication. Numerous other aspects are described.
