  • Patent number: 11910370
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.

  • Patent number: 11751152
    Abstract: In one aspect, an extended SSB (ESSB) is provided that includes more than four symbols to facilitate UE reception of SSBs. In this aspect, the base station configures an ESSB comprising an SSB including four symbols and an initial symbol preceding the SSB. The base station transmits and the UE receives at least a portion of the ESSB. The UE processes the ESSB. Thus, higher capacity UEs can benefit from additional coding gain in the initial symbol while lower capacity UEs can switch beams to receive back-to-back ESSBs. In another aspect, a UE performs additional behaviors to receive SSBs. In this aspect, the UE receives a first SSB using a reception beam, and the UE determines to maintain the reception beam for a second SSB or to switch the reception beam during a PSS symbol of the second SSB. Thus, lower capacity UEs can also receive back-to-back SSBs.
