Abstract: Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a first acknowledgment message over a sidelink feedback channel. The wireless device transmits second control information through the sidelink control channel specifying one or more second time slots for the wireless device to receive a second acknowledgment message over the sidelink feedback channel. The first and second time slots at least partially overlap, and it is determined whether the first data packet or the second data packet has a higher priority. The acknowledgment message associated with the higher priority data packet is transmitted or received during at least a subset of the overlapping time slots.

Abstract: Improved solutions for reliable physical channel, e.g. Physical Downlink Shared Channel (PDSCH) reception during wireless communications, for example during 3GPP New Radio (NR) communications include continuous channel repetitions that cross slot boundaries, channel repetitions with multiple frequency hops, and joint-repetition channel estimation that uses demodulation reference signals from at least two channel repetitions for the channel estimation. In one aspect, reliable PDSCH reception may have the benefit of aiding target UEs and serving base stations in implementing reliable Multicast and Broadcast Services (MBS).

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a channel state information (CSI) reporting configuration communication for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include a first group of CMR (Channel Measurement Resource) resources for the first TRP, and a second group of CMR resources for the second TRP. A CSI measurement communication received from the UE, may be measurements based on the CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: Techniques discussed herein can facilitate listen before talk procedures for clear channel assessment signaling. One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive system information including a region indication for clear channel assessment (CCA) procedures. The CCA procedures are associated with a listen before talk (LBT) region configuration for one of a first region, a second region, or a third region. One or more processors are configured to receive a downlink control information (DCI) in a physical downlink control channel (PDCCH) message that includes a DCI CCA indication. Subsequently, the one or more processors are configured to perform an initial LBT procedure associated with the region indication and generate a random access channel (RACH) message after performing the initial LBT procedure. Finally, the one or more processors generate an uplink (UL) message according to the DCI CCA indication.

Abstract: A receiving user equipment (UE) may be configured perform operations relating to sidelink communications with a transmitting UE. The receiving UE may establish a sidelink session with a transmitting UE, perform a local sensing, receive a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), and reserved multiple resources from the transmitting UE, whereby the transmitting UE reserves the reserved multiple resources. The receiving UE determines whether a coordination message is triggered and, in response to the coordination message being triggered, the receiving UE transmits the coordination message to the transmitting UE, the coordination message indicating whether a collision occurs among the reserved multiple resources.

Abstract: Disclosed are techniques for reducing likelihood of Random Access Channel (RACH) transmission blockages and thereby facilitate an initial access procedure for new radio (NR) unlicensed spectrum (NR-U) operation in a fifth generation (5G) wireless communication system including an NR node. In some embodiments, a parameter generated by a gNB and received by a UE indicates that, from among a set of consecutive RACH Occasions (ROs), a gap is available for performing a listen-before-talk (LBT) procedure before commencing a RACH transmission.
