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, methods, apparatuses, and computer program products for beam prediction by a user equipment using angle assistance information are provided. For example, a method can include receiving assistance information from a network and measuring a plurality of reference signal transmissions from the network. The method can also include predicting best beam or reference signal received power using a model at a user equipment. The assistance information and the measurements of the plurality of reference signal transmissions are input to the model. Reporting the best beam or reference signal received power as predicted to the network can also be performed.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system includes receiving, from a base station, configuration information associated with at least one first reference signal (RS), receiving, from the base station, reconfiguration information associated with at least one second RS, and identifying a pathloss-RS (PL-RS) for measuring a downlink pathloss based on the configuration information and the reconfiguration information, wherein a first transmission density of the at least one first RS is greater than a second transmission density of the at least one second RS.

The disclosure provides a method for performing dynamic cross-link interference (CLI) measurement and reporting in a mobile communication system. In accordance with an aspect of the disclosure, the method performed by a terminal comprises: receiving, from a base station, first information for a measurement object associated with a CLI and second information for a report configuration, the first information including at least one of configuration for sounding reference signal (SRS) resources and configuration for resources to measure a received signal strength indicator (RSSI) associated with the CLI; obtaining a reference signal received power (RSRP) of at least one SRS based on the SRS resources and at least one bandwidth part (BWP) identifier (ID) included in the configuration for the SRS resources,; and transmitting, to the base station, a measurement report including the RSRP based on the second information.

This application relates to a communication method, apparatus, and system. One example method includes: a first terminal device initiates RRC reestablishment in a first manner when determining that a second terminal device cannot continue to provide a relay service to the first terminal device, where the first manner is determined based on first information, and the first manner is a manner of initiating RRC reestablishment through a Uu interface, a manner of initiating RRC reestablishment through a new terminal device, or a manner of initiating RRC reestablishment through the second terminal device.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain per-beam, per-component carrier measurements for unique combinations of beams and component carriers supported by the UE. The UE may select a first beam that has a highest per-beam, per-component carrier measurement across all component carriers. In addition, the UE may determine a set of candidate beams based on the measurements. For example, beams included in the set of candidate beams may have per-beam, per-component carrier measurements within some defined value of the measurements corresponding to the first beam. The UE may select an active beam from the set of candidate beams based on an average per-beam, per-component carrier measurement or a difference between maximum and minimum per-beam, per-component carrier measurements of each candidate beam across all component carriers. The UE may communicate with the network entity using the active beam.

One or more wireless devices may determine whether to initiate repetition of a transmission, based on characteristics of communications link, such as in a non-terrestrial network (NTN). Characteristics of the communications link may comprise, for example, distance/length, propagation delay, elevation angle, and/or reference signal received power (RSRP). Different random access resources may be used to indicate whether repetition is initiated.

Methods and apparatuses for physical uplink control channel (PUCCH) transmission with hybrid automatic repeat request-acknowledgement (HARQ-ACK) information in a wireless communication system. A method performed by a user equipment (UE) includes receiving information for a first set of PUCCH resources for a transmission of a PUCCH on a primary cell and a set of numbers for repetitions of the transmission of the PUCCH and receiving a physical downlink control channel (PDCCH) providing a downlink control information (DCI) format that includes a downlink assignment index (DAI) field and a PUCCH resource indicator field. The method further includes determining a PUCCH resource from the first set of PUCCH resources based on the PUCCH resource indicator field; determining the number of repetitions, from the set of numbers of repetitions, based on the DAI field; and transmitting the PUCCH with the number of repetitions using the PUCCH resource on the primary cell.
