发明名称 LOW LATENCY PHYSICAL UPLINK CONTROL CHANNEL WITH SCHEDULING REQUEST AND CHANNEL STATE INFORMATION
摘要 Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may use low latency communications to improve the throughput of a wireless link. To facilitate efficient low latency communication, the UE may send UE-initiated CSI reports in addition to periodic and base station-initiated reports. For example, the UE may, in various examples, send UE-initiated CSI reports using contention based spectrum, using a request-to-transmit, or using a CSI differential (i.e., an indicator of a change in channel conditions). The base station may schedule different UEs for uplink low latency communication by providing resources to each UE for CSI and scheduling requests (SRs) using coherent or non-coherent uplink transmissions. The CSI and SR may also be combined with uplink feedback.

主权项 1. A method of wireless communication, comprising: determining channel state information (CSI) for a communication link that uses a first transmission time interval (TTI) duration in a system that supports operation with the first TTI duration and a second TTI duration that is greater than the first TTI duration; identifying resources of an unscheduled uplink channel on which to transmit a report with the determined CSI; and transmitting the report on the identified resources.
