Abstract
A wireless device receives first configuration parameters of a SR configuration associated with recovery from an LBT event comprising a plurality of LBT failures. The wireless device may trigger the LBT event for first cell(s). In response to no uplink resources, on second cell(s) for which the LBT event is not triggered, being available for transmission of an LBT failure control element, the wireless device may transmit a SR via a SR resource based on the first configuration parameters. At least one of the SR resource and the SR configuration may indicate a serving cell. The wireless device may transmit the LBT failure control element based on an uplink grant for the serving cell.
Claims20
A method comprising:
- receiving, by a wireless device, first configuration parameters of a scheduling request (SR) configuration associated with recovery from a listen-before-talk (LBT) event comprising a plurality of LBT failures;
- triggering the LBT event for one or more first cells;
- in response to no uplink resources, on one or more second cells for which the LBT event is not triggered, being available for transmission of an LBT failure control element, transmitting a SR via a SR resource based on the first configuration parameters;
- wherein:
- the SR indicates a request for uplink resources;
- and
- the request excludes resources on the one or more first cells;
- and
- transmitting the LBT failure control element based on an uplink grant.
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive first configuration parameters of a scheduling request (SR) configuration associated with recovery from a listen-before-talk (LBT) event comprising a plurality of LBT failures;
- trigger the LBT event for one or more first cells;
- in response to no uplink resources, on one or more second cells for which the LBT event is not triggered, being available for transmission of an LBT failure control element, transmit a SR via a SR resource based on the first configuration parameters;
- wherein:
- the SR indicates a request for uplink resources;
- and
- the request excludes resources on the one or more first cells;
- and
- transmit the LBT failure control element based on an uplink grant.
