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.

RLC AM selective retransmission and window movement

Methods, apparatuses, systems, and computer programs for ciphering information in a physical layer of a wireless communications network are disclosed. In one aspect, a method can include obtaining, by a UE, a transport block for transmission using the physical layer, determining, by the UE, whether the size of the transport block satisfies a predetermined threshold, and based on a determination, by the UE, that the size of the transport block satisfies a predetermined threshold size: ciphering, by the UE, the entire transport block, and transmitting, by the UE and to an access node, the ciphered transport block using the physical layer.

Dynamic length security in the physical layer

The present application relates to devices and components including apparatus, systems, and methods for beam management operations in wireless communication systems.

Parallel beam management in new band combinations

When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Mechanisms for radio link failure (RLF) reporting to network

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.

Autonomous user equipment (UE) beam failure recovery (BFR) abort

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.

Master information block decoding based on synchronization signal block timing

A user equipment (UE) may perform configured to perform layer 1 (L1) measurements and layer 3 (L3) measurements. The UE receives a first configuration for layer 1 (L1) measurements of a resource set comprising a plurality of reference signals (RS) and a second configuration for layer 3 (L3) measurements, the first configuration including periodic measurement occasions and a reporting periodicity for transmitting measurement reports comprising the L1 measurements, determines the L3 measurements collide with at least one of the plurality of RSs for the L1 measurements, wherein the colliding causes a determination of the L1 measurements to be muted for the at least one RS during at least one of the measurement occasions and alters at least a first measurement report so that the L1 measurements that collide with the L3 measurements are not reported in at least one reporting periodicity.

Measurement enhancement for L1-RSRP

The present application relates to devices and components including apparatus, systems, and methods to provide uplink spatial relation switch delay for an uplink spatial relation switch based at least in part on a pathloss reference signal associated with uplink spatial relation switch.

Uplink spatial relation switch delay

A user equipment (UE) may be configured to perform layer 1 (L1) measurement procedures and layer 3 (L3) measurement procedures. The UE configures a channel state information-reference signal (CSI-RS) layer 3 (L3) measurement window, identifies a collision between a layer 1 (L1) measurement operation and a L3 measurement operation and omits at least one L1 measurement in response to identifying the collision.

Layer 1 and layer 3 measurement coordination

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.

Methods for pathloss reference signal activation

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.
