Abstract
A method by a wireless device includes receiving, from a network node, a command associated with a procedure to setup or release a cell or a signal. While transmitting a Hybrid Automatic Repeat Request (HARQ), feedback associated with the procedure to setup or release the cell or signal, the wireless device detects one or more clear channel assessment (CCA) failures on an uplink signal. The wireless device extends a transmission period for transmitting the HARQ feedback associated with the procedure to setup or release the cell or signal based on the one or more CCA failures.
Claims25
A method performed by a wireless device, the method comprising:
- receiving, from a network node, a command associated with a procedure to activate or deactivate a secondary cell, SCell;
- while transmitting a Hybrid Automatic Repeat Request, HARQ, feedback associated with the procedure to activate or deactivate the SCell, detecting one or more clear channel assessment, CCA, failures on an uplink signal;
- and
- based on a number of times the wireless device is unable to send the HARQ feedback due to the one or more CCA failures on the uplink signal, extending a time period duration for transmitting the HARQ feedback associated with the procedure to activate or deactivate the SCell.
A method performed by a wireless device, the method comprising:
- while performing a procedure to activate or deactivate a secondary cell, SCell, detecting one or more clear channel assessment, CCA, failures;
- and
- determining an interruption window during which the wireless device is unable to transmit or receive due to the CCA failure, and
- wherein the interruption window comprises a time period duration during which the wireless device is unable to transmit or receive due to a number of times the wireless device is unable to send HARQ feedback due to the one or more CCA failures on the uplink signal.
