Abstract: An apparatus, e.g., a UE, for selecting an uplink precoder using a non-codebook-based procedure is disclosed. The UE may receive, from a base station (BS), at least one downlink reference signal comprising at least one DMRS via at least one downlink channel. The UE may measure, based on the at least one downlink reference signal, the at least one downlink channel. The measuring may be based at least in part on the at least one DMRS. The UE may select at least one first uplink precoder for at least one uplink channel corresponding to the at least one downlink channel based on the measuring of the at least one downlink channel. The UE may transmit, to the BS, at least one uplink reference signal based on the at least one first uplink precoder for the at least one uplink channel.

Abstract: Aspects of the present disclosure provide techniques for adjusting the density and/or number of random access channel (RACH) occasion for one or subset of synchronization signal block (SSB) beams from the plurality of available SSB beams. To this end, features of the present disclosure utilize a beam-specific bit-field that is transmitted by the base station to the user equipment (UE) that may indicate RACH occasion density for a SSB beam or a subset of SSB beams. In some aspects, the time and frequency resources for RACH occasion with beam-specific alternative density may be identified via the resources for general RACH occasions. Based on the adjusted RACH occasion density, the UE may select one or time and frequency resources to initiate access with the base station.

Abstract: A user equipment (UE) may receive at least one lean synchronization signal block (SSB), each of the at least one lean SSB being received in one of at least one symbol and each of the at least one lean SSB including the same kind of synchronization signal in each of the at least one symbol from a base station, measure at least one quantity associated with the received at least one lean SSB, and transmit a measurement report indicating the measured at least one quantity associated with the received at least one lean SSB to the base station for the purpose of beam management. The UE may receive a configuration indicating a lean SSB resource set. The UE may also receive an instruction to activate/deactivate or trigger the lean SSB and the measurement associated with the received lean SSB resource set when the type is semi-persistent or aperiodic, respectively.

Abstract: A UE may receive, from a base station, a first and second configurations of first and second periodic resources, receive, from the base station, a metric for switching between the first and second configurations, and switching from the first configuration to the second configuration based on the metric received from the base station. The first and second configurations may be CG of uplink resources for uplink channels. The first and second configurations may indicate SPS resources for downlink channels. The base station may determine the metric based on at least one measurement of signal at the base station or scheduling requirements.

Abstract: In embodiments of systems and methods for managing communication between a wireless device and a base station, a base station may transmit Remaining Minimum System Information (RMSI) Downlink Control Information (DCI) indicating time and frequency resources for RMSI. A wireless device may receive a Channel State Indicator-Reference Signal (CSI-RS) based on the time and frequency resources for RMSI and may select a sub-beam of a beam associated with a synchronization signal block (SSB). The wireless device may send to the base station an indication of the selected sub-beam associated with the SSB in a Physical Random Access Channel (PRACH) message. The base station and the wireless device each may then perform an initial access procedure using the selected sub-beam to enable the wireless device to establish a communication link with the base station.

Abstract: Embodiments include systems and methods for UE signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the UE of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the UE supports a CRS function, and including an indication in a response to the INVITE that the UE supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the UE only if the UE indicates CRS functional capability.

Abstract: Aspects relate to configuration of a single sounding reference signal (SRS) resource set for a UE that includes SRS resources associated with multiple, different transmission and reception points (TRPs). A radio access network (RAN) entity, which may be associated with one or more of the TRPs, may configure an SRS configuration for the SRS resource set and transmit the SRS configuration to the UE. The UE may then transmit a plurality of SRS(s) to the multiple TRPs in accordance with the SRS configuration. Other aspects, features, and examples are also claimed and described.

Abstract: Some techniques and apparatuses described herein enable a base station to configure a CSI-RS resource set with one or more parameters that are linked to one or more parameters of least one of a message that triggers CSI-RS monitoring, a physical channel associated with the CSI-RS monitoring, or an uplink reference signal associated with the CSI-RS monitoring. This allows the one or more parameters of the CSI-RS resource set to be dynamically set and/or adjusted based at least in part on the one or more parameters to which the one or more parameters of the CSI-RS resource set are linked. As a result, scheduling flexibility for beam management, downlink communications, and/or uplink communications may be increased. This may reduce delays and increase network speed, reliability, and/or beam management efficiency. Numerous other aspects are provided.
