  • Patent number: 12022521
    Abstract: Aspects relate to random access procedures. A base station may transmit a random access response message to a user equipment (UE) on a downlink control channel at a first monitoring occasion and transmit at least one repetition of the random access message at at least one offset from the first monitoring occasion. The base station may also transmit an indication of the offset(s) to the UE. Upon receiving the indication of the offset(s), the UE may monitor for the random access response message on the downlink control channel at the first monitoring occasion and at the monitoring occasion(s) for the repetition(s). A UE may identify a first radio network temporary identifier (RNTI) used to affect a physical downlink control channel (PDCCH) sent within a random access response (RAR) window and determine based on the first RNTI that the PDCCH is one of a plurality of PDCCH repetitions.

  • Patent number: 12015938
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may receive a periodic reference signal from a base station and may measure the periodic reference signal as part of a beam failure detection (BFD) procedure. To detect a beam failure, the UE may autonomously select a beam failure indicator (BFI) counting scheme from a set of BFI counting schemes and may increment a BFI count in accordance with the selected BFI counting scheme and based on measuring the reference signal. The different BFI counting schemes of the set of BFI counting schemes may feature different techniques or methods for incrementing the BFI count per one or more BFI reports. As such, the UE may selectively choose how to weight different sets of one or more BFI reports in terms of contribution to the BFI count, which may improve BFD detection at the UE.
