  • Method and apparatus for processing data, user equipment and computer-readable storage medium
    Patent number: 11558494
    Abstract: A method of processing data includes: receiving, by a Packet Data Convergence Protocol (PDCP) layer, a PDCP Service Data Unit (SDU) from an upper layer; and deleting the PDCP SDU and a PDCP Packet Data Unit (PDU) corresponding to the PDCP SDU upon determining that a discard timer corresponding to the PDCP SDU is not expired and a preset condition is satisfied. The PDCP SDU is mapped to an Unacknowledged Mode (UM) or a Transparent Mode (TM) of a Radio Link Control (RLC) layer. Thus, the PDCP SDU will not reside in a UE cache, thereby reducing cache space occupied by the PDCP SDU.
