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.

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, 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.

Abstract: 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).

Abstract: The present application relates to scheduling SSB measurements on SSB beams. In an example, a base station can transmit SSBs on SSB beams that form a serving cell. Depending on an SSB measurement on one of the SSB beams, a UE can schedule an additional SSB measurement on this SSB beam only or schedule SSB measurements on the different SSB beams.

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 apparatus to be implemented in a user equipment (UE), the apparatus comprising hardware circuitry to activate a timer for transmitting a measurement report to a base station; output a filtered signal value from a measured signal using a first parameter; determine a trend in signal quality based on the first filtered signal value and a second filtered signal value based on a second parameter; or some processing of the values either from the first filter or from the received signal; and determine whether to deactivate the timer based on the trend in signal quality. The filtered signal can be generated using a first layer 3 filter using network-configured parameters and a second layer 3 filter using proprietary parameters. Processing of the values can also be done using proprietary parameters and techniques.
