Method and apparatus for handling time-sensitive transmission
Embodiments of the present application are directed to a method and apparatus for handling time-sensitive transmission. The method may include: determining there is an overlap between a first time period for performing a measurement and a second time period for data transmission or data reception; and determining whether the data transmission or the data reception is performed based on a rule.
1 . A method performed by a user equipment (UE), the method comprising:
receiving an indicator of an urgent state for data transmission, wherein the indicator of the urgent state is triggered by a negative acknowledgement (NACK) received in a medium access control (MAC) layer; and
performing a data submission procedure according to the urgent state, the data submission procedure including activating packet data convergence protocol (PDCP) duplication and associated radio link control (RLC) entities for the PDCP duplication of protocol data units (PDUs), the PDCP duplication is activated when reference signal receiving power (RSRP) of a cell corresponding to a primary logic channel for packet duplication is lower than a first threshold and RSRP of a cell corresponding to a second logical channel for the packet duplication is higher than a second threshold.
2 . The method of claim 1 , wherein the urgent state is configurable per data radio bearer (DRB).
3 . The method of claim 2 , wherein the DRB is usable for communication services with survival time.
4 . The method of claim 1 , wherein the PDCP duplication is configured for a quality of service (QoS).
5 . The method of claim 1 , further comprising:
receiving an additional indicator of a normal state; and
deactivating the PDCP duplication based at least in part on the additional indicator of the normal state.
6 . The method of claim 5 , wherein the normal state is indicated by a successful reception.
7 . A user equipment (UE) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive an indicator of an urgent state for data transmission, wherein the indicator of the urgent state is triggered by a negative acknowledgement (NACK) received in a medium access control (MAC) layer; and
perform a data submission procedure according to the urgent state, the data submission procedure including to activate packet data convergence protocol (PDCP) duplication and associated radio link control (RLC) entities for the PDCP duplication of protocol data units (PDUs), the PDCP duplication is activated when reference signal receiving power (RSRP) of a cell corresponding to a primary logic channel for packet duplication is lower than a first threshold and RSRP of a cell corresponding to a second logical channel for the packet duplication is higher than a second threshold.
8 . The UE of claim 7 , wherein the urgent state is configurable per data radio bearer (DRB).
9 . The UE of claim 8 , wherein the DRB is usable for communication services with survival time.
10 . The UE of claim 7 , wherein the PDCP duplication is configured for a quality of service (QoS).
11 . The UE of claim 7 , wherein the at least one processor is configured to cause the UE to:
receive an additional indicator of a normal state; and
deactivate the PDCP duplication based at least in part on the additional indicator of the normal state.
12 . The UE of claim 11 , wherein the normal state is indicated by a successful reception.
