  • Publication number: 20240147534
    Abstract: Methods, systems, and devices for wireless communications are described that provide for mitigation of interference related to full-duplex communications for random access channel (RACH) initial access procedures in shared radio frequency spectrum. A user equipment (UE) may send different RACH preambles subsequent to a channel access procedure, based on whether full-duplex communications or half-duplex communications are being used at a corresponding network entity. The different RACH preambles may include a longer RACH preamble that is used when full-duplex is present, and a shorter RACH preamble that is used when full-duplex is not present. The shorter or longer RACH preamble may be used, for example, based at least in part on an open-loop transmit power for the RACH procedure, a RACH occasion configuration that provides different preamble lengths for different RACH occasions, a full-duplexing type that is being used, or any combinations thereof.

  • Publication number: 20240137195
    Abstract: Aspects are provided which allow for a UE or a base station to handle CG or SPS occasions that fall in a partially full-duplex slot. Initially, the UE receives an indication of a configured grant (CG) or a semi-persistent scheduling (SPS) configuration for allocating CG or SPS occasions. Next, the UE determines whether the CG or SPS occasion overlaps in at least one SBFD symbol in a partially full-duplex slot based on the CG or SPS configuration. Afterwards, the UE communicates with a base station according to a modification to the CG or SPS occasion based on the CG or SPS occasion overlapping in at least one SBFD symbol in the partially full-duplex slot. As a result, the UE and the base station may handle instances where a CG or SPS occasion falls in a partially full-duplex slot without identifying an error conditions or simply dropping the CG or SPS occasion.

  • Publication number: 20240137145
    Abstract: MAC-CE based dynamic MCS tables switching is introduced to support addition of higher modulation orders and new constellation types. First, a UE receives a RRC configuration indicating a plurality of MCS tables. Next, the UE receives a MAC CE activating a MCS table among the plurality of MCS tables. Doing so allows MCS tables to be dynamically switched via a MAC-CE based activation/reactivation adaptive to current signal to noise (SNR)/spectral efficiency (SPEF) experienced in a downlink and uplink. Finally, the UE communicates data with a base station using a MCS in the activated MCS table.
