    摘要： Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

    摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a hybrid automatic repeat request (HARQ) process identifier for a communication between the UE and a base station using a semi-persistent scheduling (SPS) configuration or a configured grant (CG) configuration, wherein the determination of the HARQ process identifier is based at least in part on an offset applied for the determination of the HARQ process identifier; and perform the communication based at least in part on the HARQ process identifier.. Numerous other aspects are provided.

    摘要： Rate-matching and channel estimation are disclosed for new radio (NR) user equipments (UEs). An NR UE obtains coexistence information of neighboring legacy operations including common reference signal (CRS) ports, CRS frequency pattern, and a legacy subframe type corresponding to the NR transmission segments. The NR UE determines legacy CRS occasion(s) coinciding with shared downlink direction operations for the NR and legacy operations, and rate-matches reception of NR downlink transmissions around the CRS occasion(s). In other aspects, an NR UE detects overlap of a downlink signal with downlink control channel candidate of a configured control resource set (CORESET). The UE ends monitoring of the candidate within a search space of the CORESET in response to the detected overlap, detects a collision between a scheduled demodulation reference signal (DMRS) and the downlink signal occasion, and discards all or part of the CORESET.
