Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE reports, to a base station, a reduced PDCCH monitoring capability for at least one group of search space sets (SSS) of a PDCCH, receives, from the base station, a reduced monitoring capability (MO) configuration, wherein the base station determines the reduced MO configuration based on the reported reduced PDCCH monitoring capability and monitors the PDCCH based on the reduced MO configuration.

Abstract: An evaluating user equipment (UE) includes memory and one or more processors communicatively coupled to the memory. The one or more processor are configured to schedule periodic resources with one or more configured feedback-based collision detection parameters, and perform a periodic transmission to one or more receiving UEs. The one or more processors are also configured to collect negative acknowledgement (NACK) statistics for the periodic transmission according to the configured feedback-based collision detection parameters, and selectively perform corrective action based on the collected NACK statistics and at least one of the configured feedback-based collision detection parameters.

Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

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: 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.

Abstract: A base station or other network component (next generation NodeB (gNB)) can operate to transmit a channel state information reference signal (CSI-RS) for channel state information (CSI) feedback. The CSI feedback can be received as corresponding to one or more frequency parts at hierarchical precoding levels of a frequency band based on a hierarchical precoding scheme in response to providing the CSI-RS.
