  • Patent number: 12634057
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may account for the application of orthogonal cover coding (OCC) to an uplink transmission when determining the transport block size (TBS) for the uplink transmission. OCC may be used to multiplex transmissions from multiple UEs and may involve spreading information. Described techniques may involve accounting for the spreading of information bits when determining the TBS for the uplink transmission to which OCC is applied. Sub-physical resource block (sub-PRB) frequency allocations may be provided for uplink transmissions. The UE may account for the allocated quantity of sub-carriers when determining the quantity of information bits. To indicate a sub-PRB, the UE may be configured to reinterpret one or more fields of an existing downlink control information (DCI) format as indicating the allocated sub-carriers, or a new DCI format may be configured that includes fields for indicating a sub-PRB allocation.

  • Patent number: 12634952
    Abstract: Methods, systems, and devices for wireless communication are described. In some aspects, a network entity may encode, at an application layer, multiple internet protocol (IP) packets with an application level outer code to generate outer encoded IP packets. In such aspects, the network entity may generate, for each of the outer encoded IP packets, a medium access control (MAC) packet data unit (PDU) at a MAC layer. In one aspect, the network entity may map each MAC PDU to a respective code block of a single transport block (TB) and broadcast the TB. Alternatively, the network entity may map each MAC PDU to a single codeblock of a respective TB and broadcast the TB via a single time slot. In some other aspects, the network entity may perform physical or MAC layer outer encoding on the IP packets, where the network entity may perform outer encoding on multiple MAC PDUs.

  • Patent number: 12634002
    Abstract: This disclosure provides systems, methods and apparatus for enabling multi-TRP transmission in non terrestrial networks. In one aspect, a user equipment receives a first reference signal from a first satellite transmission reception point (TRP) at a first timing and receives a second reference signal from a second satellite TRP at a second timing. The first timing is synchronized with the second timing at a first geographic location. The user equipment receives a third reference signal from the first satellite TRP at a third timing and receives a fourth reference signal from the second satellite TRP at a fourth timing. The third timing and the fourth timing are synchronized at the user equipment. The user equipment receives an indication of a timing offset of the fourth reference signal with respect to the second reference signal and uses the third and fourth reference signals as a quasi colocation (QCL) source.

  • Publication number: 20260135687
    Abstract: Methods, systems, and devices for wireless communication are described. Various aspects generally relate to segmented pre-compensation schemes that account for time division duplexing (TDD) patterns involving periodic valid uplink subframes. Some aspects more specifically relate to a segmented pre-compensation scheme according to which a user equipment (UE) may reset a segment duration in a next valid uplink subframe in accordance with an interruption, by an invalid uplink subframe associated with a TDD pattern, of a segment within a prior valid uplink subframe. The UE may perform a time or frequency adjustment at or prior to the segment duration reset in the next valid uplink subframe. For example, if a first segment is interrupted by an invalid uplink subframe, the UE may transmit a postponed portion of the uplink message within a next valid uplink subframe in accordance with a new time or frequency adjustment.

  • Publication number: 20260135684
    Abstract: Methods, systems, and devices for wireless communications are described that provide for random access techniques for low duty-cycle time division duplexing (TDD) communications. Random access preamble transmissions may use transmission resources associated with one or more preamble repetition units (PRUs), where a PRU may at least partially overlap with transmission resources that are not valid for a transmission. In such cases, all or a portion of the random access transmissions of the PRU may be postponed to a next valid uplink communication resource. Postponement of random access transmissions may be performed at a symbol-group level for symbol groups within a PRU, or at a PRU level. Further, radio network temporary identifiers (RNTIs) associated with random access transmissions may be identified based on a system frame associated with an initial transmission occasion of the random access transmission, or the postponed transmission occasion.
