Abstract
A wireless device receives configuration parameters of an unlicensed cell. The wireless device may receive a DCI indicating a downlink assignment or a release of a SPS configuration. The wireless device may transmit a HARQ feedback, associated with the DCI, via the unlicensed cell. The transmission of the HARQ feedback may be based on multiplexing the HARQ feedback in a first HARQ feedback codebook and using one or more first unlicensed parameters, for transmission via the unlicensed cell, in response to the DCI being associated with a first priority. The transmission of the HARQ feedback may be based on multiplexing the HARQ feedback in a second HARQ feedback codebook and using one or more second unlicensed parameters, for transmission via the unlicensed cell, in response to the DCI being associated with a second priority.
Claims20
A method comprising:
- receiving, by a wireless device, configuration parameters of an unlicensed cell;
- receiving a downlink control information indicating an assignment for a downlink transport block (TB) or release of a first semi-persistent scheduling (SPS) configuration;
- wherein the downlink TB or the first SPS configuration is associated with one of a first priority and a second priority;
- and
- transmitting a hybrid automatic repeat request (HARQ) feedback via the unlicensed cell and based on:
- a first HARQ feedback codebook and one or more first unlicensed parameters in response to the downlink TB or the first SPS configuration being associated with the first priority;
- and
- a second HARQ feedback codebook and one or more second unlicensed parameters in response to the downlink TB or the first SPS configuration being associated with the second priority.
