Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.

Enhanced CSI reporting for multi-TRP operation

A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Full power uplink transmission enhancement

Systems and methods provide a channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A user equipment (UE) triggers measuring of a CSI reference signal (CSI-RS) from a base station. The UE triggers measuring of a DMRS for a PDSCH transmission from the base station. The UE generates a CSI report to report the CSI measurement, based on both the CSI-RS and the DMRS for the PDSCH transmission. The UE may then send the CSI report to report the CSI measurement to the base station.

Systems and methods for PDSCH based CSI measurement

Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

Methods and apparatus for scheduling availability/restriction and measurement sharing for SSB based inter-frequency measurement without measurement gap

This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A transmission control indication state may be indicated for future monitoring of a control channel, e.g., using one or more rules. The indicated state may be used to provide and receive control information for performing multi-transmission and reception point operation.

Mapping unified transmission states for multipoint control channel reception using rules

To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Physical broadcast channel extension in wireless communications

A user equipment (UE) reports channel state information for multiple transmission reception points (TRPs) to a network. The UE collects channel state information (CSI) corresponding to multiple transmission reception points (TRPs), receives a signal configured to trigger a semi-persistent CSI (SP-CSI) report from a first TRP of the multiple TRPs, generates a SP-CSI report that includes CSI corresponding to each TRP of the multiple TRPs and transmits the SP-CSI report to a cell associated with the multiple TRPs.

Reporting channel state information for multi-TRP operation

Systems and methods for user equipment (UE) capable of performing sidelink (SL) communications that account for overlapped SL resource pools of multiple radio access technologies (RATs) are disclosed. A UE may select, based on prioritizing non-overlapped resources over overlapped resources, one or more candidate resources and/or one or more transmission resources; may determine a power control configuration without considering SL pathloss corresponding to a first RAT when a second power control configuration determination for a second RAT does not consider SL pathloss; may select physical sidelink feedback channel (PSFCH) locations for PSFCH use from first PSFCH locations of resources of a first SL resource pool on a first RAT that do not overlap with a second SL resource pool on a second RAT according to a bitmap; and/or may select one of a PSFCH transmission and PSFCH reception using a data priority rule and/or a pool sharing rule.

Resource allocation for co-channel coexistence

A method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device that specifies PDCCH monitoring for one subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs) that are related to a spectrum in 5G new radio (NR) above 52.6 GHz are described. In one embodiment, the monitoring limits associated with each of the SCSs are applied per slot per CC and the user equipment (UE) decode complexity associated with performing the monitoring limits for the different SCSs in the group is equal. In one embodiment, the monitoring limits associated with each of the SCSs are for a slot group of a plurality of slots and are for application over a duration of the slot group.

System and methods for PDCCH monitoring in new radio

Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

Systems and methods for beam failure recovery enhancement

A user equipment (UE) reports beam management information to a network. The UE receives a first group of multiple reference signals from a first transmission reception point (TRP) of a network, receives a second group of multiple reference signals from a second different TRP of the network, selects a first beam associated with one of the multiple reference signals of the first group, selects a second beam associated with one of the multiple reference signals of the second group and transmits a message to the network, the message including an indication of the selected first beam and second beam.

UE operations for beam management in multi-TRP operation

A method determines a number of physical sidelink shared channel (PSSCH) symbols and a number of PSSCH demodulation reference signal (DMRS) symbols that will occur in a timeslot that is used for scheduling. PSSCH DMRS locations in the timeslot are derived based on applying the PSSCH DMRS symbols and the PSSCH DMRS symbols to a look-up table. A number of PSSCH DMRS resource elements (REs) is calculated based on the PSSCH DMRS locations and a scheduled number of PSSCH sub-channels. This number of PSSCH DMRS REs is used to determine a transport block size (TBS) included in transmissions over a sidelink channel.

Determine a transport block size (TBS) included in transmissions over a sidelink channel

Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

Enhanced machine type communications (MTC) for non-terrestrial networks (NTN)

A user equipment (UE) is configured to receive message 3 (Msg3) transmissions. The UE receives a system information block (SIB) transmission from a base station of a wireless network, receives a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission from the base station, receives the Msg2 transmission including an uplink (UL) grant for a message 3 (Msg3) initial transmission from the base station, determines the number of repetitions for the Msg3 initial transmission based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission and determines a frequency hopping (FH) type and FH pattern based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission.

Enhancement of message 3 for RACH procedure

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.
