Abstract: The present application relates to devices and components, including apparatus, systems, and methods for serving data traffic on an access stratum (AS) radio bearer (RB) using independently configured bearer flows. Having their own resource sets, bearer flows remove the dependency of processing and transmission, and retransmission among different traffic flows assigned to the same AS RB.

Abstract: Systems and methods are for receiving, from a transmitter, a transport block comprising medium access control (MAC) subheader fields and data units, the transport block being divided into code block groups, a beginning of each code block group in the transport block comprising an alignment with a beginning of a respective MAC subheader field in the transport block; and based on the alignment, decoding the code block groups of the transport block.

Abstract: Methods, systems, and computer-readable mediums are configured to perform operations including detecting a plurality of synchronization signal blocks (SSBs) that are transmitted for a physical broadcast channel (PBCH), each of the SSBs having a SSB index comprising a set of bit values; detecting, from the plurality of SSBs, a first SSB received at a first time and a second SSB received at a second time that is different from the first time; decoding, for a first SSB of the plurality, first bit values of a first SSB index representing the first SSB and of a second SSB index representing the second SSB; determining, based on the first time and the second time, a receive time gap between the first SSB and the second SSB; and determining, based on the receive time gap and the first bit values of the first SSB index and the second SSB index, at least a second bit value of the first second SSB index representing the first SSB and the second SSB representing the second SSB.

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: 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.
