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: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration 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 single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.

Abstract: Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.

Abstract: A user equipment (UE) receives reference signals during a discontinuous reception (DRX) cycle to perform frequency and timing tracking or automatic gain control (AGC). The UE receives configuration information corresponding to a reference signal that is to be transmitted to a user equipment (UE) when the UE is in a first operating state, receives the reference signal from a cell of a network when the UE is in the first operating state, performs one of frequency and timing tracking or automatic gain control (AGC) using the reference signal and receives a signal from the cell during a time window that the UE is scheduled to utilize an active mode of data exchange processing.

Abstract: A user equipment (UE) is configured with multi-transmission and reception point (multi-TRP) operation. The UE groups capabilities of handling two overlapping physical downlink shared channel (PDSCH) transmissions into a plurality of groups, determining a UE capability of handling two overlapping PDSCH transmissions based on the plurality of groups and transmits the UE capability to a next generation nodeB (gNB) of a 5G new radio (NR) wireless network. The UE also determines if a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH) transmission collides with a cell-specific reference signal (CRS) of a long term evolution (LTE) transmission and determines if the CRS originated from a same multi-transmission/reception point (TRP) as the DMRS.
