Abstract
For pre-processing Packet Data Converge Protocol (PDCP) Protocol Data Units (PDU), a method receives a configuration of a reference uplink grant. In response to receiving the configuration of the reference uplink grant, the method calculates a preprocessing threshold of PDU for preprocessing by a Radio Link Control (RLC)/Medium Access Control (MAC) for each of one or more radio bearers.
Claims20
An apparatus for wireless communication at a device, the apparatus comprising:
- a processor performing:
- submitting, from a packet data convergence protocol (PDCP) to a radio link control (RLC) entity, one or more radio link control (RLC) service data units (SDUs);
- generating, by the RLC entity, one or more RLC protocol data units (PDUs) based in part on the one or more RLC SDUS, wherein each respective RLC PDU associated each respective RLC SDU comprises an RLC header;
- receiving, by the RLC entity, an indication from the PDCP entity to discard at least one RLC SDU associated with at least one generated RLC PDU of the one or more generated RLC PDUs;
- discarding, by the RLC entity, the at least one RLC SDU based in part on the received indication from the PDCP entity;
- and
- reassigning a respective sequence number associated with one or more subsequent generated RLC PDUs based in part on the at least one discarded RLC SDU.
A method of wireless communication at a device, the method comprising:
- submitting, from a packet data convergence protocol (PDCP) to a radio link control (RLC) entity, one or more radio link control (RLC) service data units (SDUs);
- generating, by the RLC entity, one or more RLC protocol data units (PDUs) based in part on the one or more RLC SDUS, wherein each respective RLC PDU associated each respective RLC SDU comprises an RLC header;
- receiving, by the RLC entity, an indication from the PDCP entity to discard at least one RLC SDU associated with at least one generated RLC PDU of the one or more generated RLC PDUs;
- discarding, by the RLC entity, the at least one RLC SDU based in part on the received indication from the PDCP entity;
- and
- reassigning a respective sequence number associated with one or more subsequent generated RLC PDUs based in part on the at least one discarded RLC SDU.
A program product for wireless communication at a device, the program product comprising a non-transitory computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:
- submitting, from a packet data convergence protocol (PDCP) to a radio link control (RLC) entity, one or more radio link control (RLC) service data units (SDUs);
- generating, by the RLC entity, one or more RLC protocol data units (PDUs) based in part on the one or more RLC SDUS, wherein each respective RLC PDU associated each respective RLC SDU comprises an RLC header;
- receiving, by the RLC entity, an indication from the PDCP entity to discard at least one RLC SDU associated with at least one generated RLC PDU of the one or more generated RLC PDUs;
- discarding, by the RLC entity, the at least one RLC SDU based in part on the received indication from the PDCP entity;
- and
- reassigning a respective sequence number associated with one or more subsequent generated RLC PDUs based in part on the at least one discarded RLC SDU.
