Abstract: To facilitate efficient mode 2 sidelink resource allocation, methods, apparatuses, and computer program products are provided. An example method of a first wireless device includes applying a power saving mode for sidelink communication, the power saving mode having an ON duration and an OFF duration. The method further includes performing at least one of sensing or resource selection for sidelink mode 2 resource allocation based on one or more parameters, the one or more parameters being based on the ON duration and the OFF duration of the power saving mode.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to maintain phase coherence for repetitions of uplink channel transmissions across slot boundaries. One example method includes receiving, from a network entity, phase coherence configuration information indicating that the UE is to maintain phase coherence for repetitions of uplink channel transmissions that cross slot boundaries; receiving scheduling information scheduling a plurality of repetitions of an uplink channel transmission; determining, based on the scheduling information, that the scheduled plurality of repetitions of the uplink channel transmission will cross one or more slot boundaries; and transmitting the plurality of repetitions of the uplink channel transmission based on the scheduling information and the phase coherence configuration information.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for providing two channel state information (CSI) reports based on sidelink CSI reference signal (RS) respectively to a sidelink user equipment (UE) and a network entity (e.g., a base station). Existing sidelink CSI reporting between UEs is not shared with the network. The lack of information on the network side prevents scheduling improvements. Therefore, by generating a second CSI report to the network, the network can have information to better schedule sidelink UE transmissions and to introduce precoding matrix indicator (PMI) signaling.

Abstract: A UE may receive, from a base station, a first configuration associated with transmitting a low priority UL channel and a second configuration associated with transmitting a high priority UL channel concurrent in time with the low priority UL channel. The UE may cancel the transmission of the low priority UL channel to transmit the high priority UL channel independently, or multiplex the low priority UL channel with the high priority UL channel to transmit both the low priority UL channel and the high priority UL channel together based on a third configuration received from the base station or at least one condition. At least one condition includes a power headroom, a coding rate of high priority data/UCI, or a percentage of resource in high UL channel that is taken by low priority UL transmissions

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink communication. The UE may receive a configuration identifying a first uplink resource for a hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second uplink resource for multiplexing channel state information (CSI) reports. The UE may receive a downlink communication. The UE may determine that a HARQ-ACK for the downlink communication is to be multiplexed with one or more CSI reports on the second uplink resource. The UE may determine that an error has occurred based at least in part on a determination that the second uplink resource configured is in a different sub-slot than the first uplink resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a synchronization signal block (SSB) from a plurality of SSBs received from a base station based at least in part on a power measurement associated with the SSB. The UE may determine a physical random access channel (PRACH) coverage enhancement (CE) level that is associated with the SSB. The UE may perform, with the base station, a PRACH transmission on PRACH resources associated with the SSB and the PRACH CE level. Numerous other aspects are provided.

Abstract: Aspects relate to radio link management for a first type of link that is a high reliability, low-latency communication link such as ultra-reliable, low-latency communication (URLLC). Radio link failure (RLF) of the link may be determined in a wireless device that then transmits a link recovery request (LRR) communicating the RLF and a request for link recovery to a network in a reserved resource in an uplink channel using a second type of link that does not have as high priority (e.g., not as high reliability or as low-latency) as the first type of link, such as enhanced mobile broadband (eMBB). The wireless device receives a grant of uplink resources from the network responsive to the LRR, where the uplink resources are used by the wireless device to transmit an RLF report to the network and are also of the second type of link.

Abstract: A method of wireless communications by a receiving sidelink user equipment includes detecting a lite sidelink synchronization signal (SL-SS) transmitted by a transmitting sidelink UE. The lite SL-SS may have a pattern with a reduced number of physical sidelink broadcast channel (PSBCH) symbols. The method also includes transmitting a demand requesting additional SL-SSs from the transmitting sidelink UE on indicated resources. Another method includes receiving a demand for additional sidelink synchronization signals (SL-SSs) from a receiving sidelink UE. This method further includes transmitting the additional SL-SSs in response to the demand.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for TDRA-based HARQ-ACK feedback generation. In aspects, a UE and a base station may determine that at least one TDRA candidate of a set of TDRA candidates for a PDSCH transmitted from a base station has more than one possible location within a slot. Based on the determination that the at least one TDRA candidate has more than one possible location within the slot, the UE may generate and transmit corresponding HARQ-ACK feedback to the base station, which may decode the HARQ-ACK feedback.
