  • Methods and apparatus related to ACK/NACK feedback with multi-TRP transmissions
    Patent number: 11177909
    Abstract: Various aspects related to ACK/NACK feedback for multi-TRP transmission scenarios are described. A base station, may send, to a UE, information indicating PDCCH monitoring occasions for each of a plurality of TRPs. In one aspect, the base station may send information indicating whether ACK/NACK feedback across the plurality of TRPs is allowed. The base station may send rules to the UE for performing ACK/NACK feedback bundling for providing feedback to the plurality of TRPs. The base station may also send information indicating a DAI definition for interpreting DAIs transmitted by the plurality of TRPs in corresponding PDCCH transmissions indicating whether the DAIs are independent or joint. The base station may receive a joint ACK/NACK feedback from the UE in a PUCCH based on the rules, or may receive multiple ACK/NACK feedback from the UE in a PUCCH for a first TRP independent from a second TRP.

  • Scheduling request transmission for directional beam access
    Patent number: 11178685
    Abstract: A user equipment (UE) may transmit a UE-generated uplink message to a base station to request resources for an uplink transmission. The UE may be configured to send the message (e.g., a scheduling request (SR)) using different transmission modes. For example, the UE may transmit the SR using a scheduled mode where the UE conveys the SR along with another uplink message (e.g., a control message). In some examples, the UE may transmit the SR using an autonomous mode where the UE transmits the SR in resources reserved for SR transmissions. The UE may determine which transmission mode to use based on certain characteristics of the SR or the data associated with the SR.
