Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations for selective re-transmission of radio link channel (RLC) service data units (SDUs). In one aspect, the method can include actions of determining that transmission of an RLC SDU having a first sequence number was not successful, determining whether to re-transmit the RLC SDU, and based on a determination that the particular RLC SDU is not to be re-transmitted: moving a start location of an RLC transmission window to an RLC SDU that (i) has a sequence number that is greater than the first sequence number and (ii) has not been acknowledged, and transmitting a transmission to another device that indicates that the RLC SDU having the first sequence number is to be skipped.

Abstract: Techniques discussed herein can facilitate autonomous user equipment beam failure recovery abort aspects. One example aspect is a baseband processor configured to perform operations including: establishing a connection with a downlink (DL) beam; detecting a beam failure of the DL beam; in response to the beam failure, executing at least one of: a beam failure recovery (BFR) procedure or a candidate beam detection (CBD) procedure; detecting a recovery abort condition while executing the at least one of: the BFR procedure or the CBD procedure; aborting the at least one of: the BFR procedure or the CBD procedure, in response to detecting that the recovery abort condition is satisfied; and maintaining the connection with the DL beam.

Abstract: An electronic device may include wireless circuitry. The wireless circuitry may include one or more antenna arrays coupled to baseband processing circuitry by parallel radio-frequency signal (receive) chains. To more efficiently perform beam measurements, and thereby more efficiently determine cell status, beam measurements may be performed by the radio-frequency receive chains in a parallel manner. If desired, beam measurements for one or more inter-frequency and/or intra-frequency layers may each be parallelized. If desired, beam measurements during a discontinuous reception mode of operation may be parallelized.

Abstract: Techniques discussed herein can facilitate autonomous user equipment beam failure recovery abort aspects. One example aspect is a baseband processor configured to, when executing instructions stored in a memory, perform operations comprising: detecting a beam failure of a downlink (DL) beam; determining that a beam recovery abort condition is satisfied after detecting the beam failure; aborting a random access channel (RACH) transmission when the beam recovery abort condition is satisfied; and maintaining a connection with the DL beam after aborting the RACH transmission.
