Abstract: Systems and methods for utilizing inter-UE coordination regarding reserved resources of a sidelink (SL) resource pool are described herein. A first user equipment (UE) may identify that a first SL resource pool on a first radio access technology (RAT) overlaps with a second SL resource pool on a second RAT, sense for reservation signaling on the second SL resource pool to determine reserved resources on the second SL resource pool, and transmit resource reservation information indicating those reserved resources on SL on the first RAT. A second UE may receive the resource reservation information on the SL, identify, within the first SL resource pool, corresponding resources that overlap with the reserved resources of the second SL resource pool, select, from the first SL resource pool, transmission resources to use for a SL transmission by prioritizing resources other than the corresponding resources; and perform the SL transmission using those transmission resources.

Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a physical shared channel based on a number of resource blocks determined by one or more formulas for a transport block size (TBS). In response to determining a result of the one or more formulas based on one or more received parameters a configured action for the physical shared channel can be determined based on the number of resource elements (REs). A radio frequency (RF) interface, is configured to provide, to RF circuitry, data for transmitting a new radio (NR) communication based on the configured action.

Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

Abstract: A method and apparatus configuring default beams are described. In some embodiments, the method of wireless communication at a User Equipment (UE) comprises: receiving, from a base station, configuration information for configuring a default beam for the physical downlink shared channel (PDSCH) to use on condition that an offset between reception of downlink control information (DCI) in the scheduling physical downlink control channel (PDCCH) and corresponding PDSCH is less than a threshold and at least one Transmission Configuration Indicator (ICI) states includes spatial receiving parameters for configuring a quasi-co-location; configuring, by the UE, a default beam configuration for the PDSCH based on the configuration information and a monitored control resource set (CORESET) with a lowest CORESET identifier (ID) from among a set of CORESETs in a latest slot in a same bandwidth part (BWP), wherein at least one CORSET of the set of CORESETs includes more than one TCI state; and receiving a transmission using the default beam.

Abstract: Systems, methods, and apparatuses for muting resource elements used for wireless communications is disclosed. In one aspect, a method can include actions of obtaining, by user equipment (UE), configuration data that indicates a frequency density of muted resource blocks, identifying, by the UE and based on a value of an antenna ports information element in downlink control information (DCI) that schedules a PUSCH transmission, a group of resource elements within the muted resource blocks, determining, by the UE, a muted resource pattern (MRP) within the RBs for the scheduled PUSCH based on the frequency density of the muted resource blocks and the identified group of resource elements, and transmitting, by the UE, an allocation of RBs for PUSCH without transmission on the identified group of resource elements of the determined MRP.
