Abstract
A method and apparatus for triggering a transmission carrier reselection procedure for deactivated duplication in a wireless communication is provided. A wireless device selects a first carrier carrying a data unit, and selects a second carrier carrying a duplication of the data unit based on activation of the duplication of the data unit. The wireless device triggers a carrier reselection procedure based on deactivation of the duplication of the data unit.
Claims8
A method performed by a wireless device configured to operate in a wireless communication system, the method comprising:
- receiving a configuration of one or more carriers from a network;
- activating and performing, at a packet data convergence protocol (PDCP) entity of the wireless device, a duplication of a data unit based on sending the data unit to both a first radio link control (RLC) entity and a second RLC entity,
- wherein the first RLC entity is associated with a first logical channel, and
- wherein the second RLC entity is associated with a second logical channel;
- selecting a first carrier, from the one or more carriers, related to the first logical channel;
- based on the duplication of the data unit, selecting a second carrier, from the one or more carriers, related to the second logical channel which is different from the first logical channel;
- performing a sidelink transmission of the data unit with the duplication on both the first carrier and the second carrier;
- and
- upon deactivation of the duplication of the data unit at the PDCP entity, triggering a carrier reselection based on i) the second carrier being selected only for the second logical channel and ii) data being not available for the second logical channel.
A wireless device configured to operate in a wireless communication system, the wireless device comprising:
- a memory;
- a transceiver;
- and
- a processor, operably coupled to the memory and the transceiver, and configured to perform operations comprising:
- receiving a configuration of one or more carriers from a network;
- activating and performing, at a packet data convergence protocol (PDCP) entity of the wireless device, a duplication of a data unit based on sending the data unit to both a first radio link control (RLC) entity and a second RLC entity,
- wherein the first RLC entity is associated with a first logical channel, and
- wherein the second RLC entity is associated with a second logical channel;
- selecting a first carrier, from the one or more carriers, related to the first logical channel;
- based on the duplication of the data unit, selecting a second carrier, from the one or more carriers, related to the second logical channel which is different from the first logical channel;
- performing a sidelink transmission of the data unit with the duplication on both the first carrier and the second carrier;
- and
- upon deactivation of the duplication of the data unit at the PDCP entity, triggering a carrier reselection based on i) the second carrier being selected only for the second logical channel and ii) data being not available for the second logical channel.
