20220369353 · 2022-11-17 ·

Techniques disclosed herein efficiently address prioritization by a UE (12) regarding its reception behavior with respect to a configured downlink transmission that is overlapped by a dynamic assignment and/or the dynamic downlink transmission scheduled via the dynamic assignment. In at least one embodiment having applicability to operation of the UE (12) in a communication network based on the 5G NR specifications, the techniques disclosed herein provide for predictable behavior by the UE (12) as to when the UE (12) prioritizes a configured Physical Downlink Shared Channel (PDSCH) versus another PDSCH. Correspondingly, a radio network node (22) may exploit the predictable behavior of the UE (12) to override a configured PDSCH in favor of a dynamic PDSCH, by transmitting the Physical Downlink Control Channel (PDCCH) that schedules the dynamic PDSCH so that a timing relationship between the PDCCH and the configured PDSCH is satisfied.

Reception of overlapping physical downlink shared channel communications

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of whether a first physical downlink shared channel (PDSCH) communication is to be punctured in a set of resources in which a second PDSCH communication at least partially overlaps with the first PDSCH communication, or both the first PDSCH communication and the second PDSCH communication are to be transmitted in the set of resources. The mobile station may decode the first PDSCH communication based at least in part on the indication. Numerous other aspects are provided.

20230051851 · 2023-02-16 ·

A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.

Search spaces and grants in eMTC

Design of search spaces and grants in enhanced machine-type communication (eMTC) is discussed in which the search space for common control information is determined based on the search space for non-common control information. In addition, the monitoring of search spaces by mobile devices is also discussed. Additionally, communication schemes between base stations and mobile devices in which information is provided in multiple transmission modes is also discussed. Other aspects discuss schemes for the transmission of control information.

Resource splitting among different types of control information and uplink data for a transmission on an uplink shared channel

Methods, systems, and devices for wireless communications are described that support splitting resources among different types of control information and uplink data for transmission on an uplink shared channel. A base station may transmit a grant indicating resource elements (REs) of an uplink shared channel allocated to a user equipment (UE) for an uplink transmission. The UE may process the grant and split the granted REs between different types of uplink control information (UCI) and uplink data based on a reference payload size. The UE may generate an uplink transmission based on the splitting of the REs, and may transmit the uplink transmission in the REs of the uplink shared channel indicated in the grant. The base station may monitor the REs of the uplink shared channel for the uplink transmission in accordance with the splitting of the plurality of REs.
