Abstract
Provided are a method for data transmission and apparatus. The method includes: receiving configuration information from a base station, the configuration information indicating whether a data packet deletion function is enabled at a PDCP entity corresponding to a preset data bearer. When the data packet deletion function is enabled, a duration for transmission of SDUs is recorded when the SDUs are transmitted from the PDCP entity corresponding to the preset data bearer to a RLC layer. A first SDU that has not yet been transmitted to the RLC layer is determined from the SDUs in a case that the duration for transmission of the SDUs is longer than a preset duration. The first SDU is deleted.
Claims22
A method for data transmission, comprising:
- receiving configuration information from a base station, the configuration information indicating whether a data packet deletion function is enabled or not at a Packet Data Convergence Protocol (PDCP) entity corresponding to a preset data bearer;
- when the data packet deletion function is enabled at the PDCP entity corresponding to the preset data bearer, recording a duration for transmission of Service Data Units (SDUs) when the SDUs are transmitted from the PDCP entity corresponding to the preset data bearer to a Radio Link Control (RLC) layer;
- determining, from the SDUs, a first SDU that has not yet been transmitted to the RLC layer, in response to that the duration for transmission of the SDUs is longer than a preset duration;
- and
- deleting the first SDU.
An apparatus for data transmission, comprising:
- a processor;
- and
- a memory configured to store an instruction executable for the processor,
- wherein the processor is configured to:
- control a transceiver to receive configuration information from a base station, the configuration information indicating whether a data packet deletion function is enabled or not at a Packet Data Convergence Protocol (PDCP) entity corresponding to a preset data bearer;
- when the data packet deletion function is enabled at the PDCP entity corresponding to the preset data bearer, record a duration for transmission of Service Data Units (SDUs) when the SDUs are transmitted from the PDCP entity corresponding to the preset data bearer to a Radio Link Control (RLC) layer;
- determine from the SDUs a first SDU that has not yet been transmitted to the RLC layer in response to that the duration for transmission of the SDUs is longer than a preset duration;
- and
- delete the first SDU.
