  • Patent number: 12149317
    Abstract: Methods and systems are disclosed for a more flexible use of bandwidth parts (BWP) and cells for the various transmissions within the BFR procedure, such as the UL beam failure recovery request (BFRQ) and the DL beam failure recovery response (BFRR). The proposed framework allows these transmission to occur in BWPs with different Id, as well as on different cells. Example benefits include support for BFR on DL-only SCells by allowing the BFR UL transmissions on another cell with UL, support for sequential/parallel multi-cell BFRQ for improved BFR reliability and latency performance, and support for less UE-initiated BWP switching for BFR.

  • Patent number: 12150146
    Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.

  • Publication number: 20240381491
    Abstract: Multicast/Broadcast Service (MBS) for user equipments (UE) in Radio Resource Control (RRC) idle/inactive modes via signally of MBS frequency ranges and/or switching between frequency ranges as required. Bandwidth Part (BWP) operation for MBS in RRC_IDLE and RRC_INACTIVE states may be implemented using a dedicated MBS BWP or by sharing a frequency range with other operations. An MBS frequency range may be wider or narrower than an initial BWP used by a UE, for example. MBS frequency range configure may be achieved in a number of ways, such as via Control Resource Set (CORESET), search space, and/or PDCCH monitoring occasions pattern settings for MBS in RRC idle/inactive. Downlink scheduling without dynamic grant for MBS in RRC idle/inactive may include configured scheduling and/or semi-persistent scheduling.
