  • Publication number: 20240235801
    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: 20240235946
    Abstract: Techniques for monitoring data transport in a network virtualization function chain (chain). A path tracing packet is generated having a Midpoint Compressed Data (MCD) to collect path tracing information of the chain. The network virtualization function node is configured to record an MCD containing Wide Local Path Tracing Identification (WL PT ID). The WL PT ID includes a first field having a value that indicates that a non-standard path tracing format is to be used and a second field that indicates a particular path tracing format to be used. The path tracing packet is passed through the chain and is received back after passing through the chain. Data collected by the path tracing packet is then analyzed to determine which network virtualization function nodes and chains the path tracing packet passed through and the amount of time taken for the path tracing packet to pass through the chain.

  • Publication number: 20240237055
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that indicates a configuration for subband full duplex (SBFD) slots and a random access channel (RACH) configuration for SBFD slots. The UE may transmit at least one instance of a RACH message in an uplink subband of an SBFD slot in accordance with the RACH configuration. The RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across an SBFD slot and an uplink slot. The RACH configuration may map synchronization signal blocks (SSB)s to RACH occasions in the uplink subband of the SBFD slot. In some examples, the SSBs may be mapped across multiple (e.g., consecutive) SBFD slots. In some cases, the RACH configuration may enable a UE to repeat a RACH message or transmit a multi-slot RACH message across multiple SBFD slots.
