Abstract
The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.
Claims15
A communication device for transmitting protocol data units (PDUs) in a wireless communication system, the communication device comprising:
- at least one transceiver;
- at least one processor;
- and
- at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising:
- submitting L number of radio link control (RLC) PDUs to a medium access control (MAC) layer;
- setting a state variable POLL_SN based on the L RLC PDUs that are submitted to the MAC layer for a transmission opportunity, where L is greater than 1;
- wherein the L RLC PDUs include more than one RLC PDU having a poll to trigger status reporting at a receiving device, and wherein the state variable POLL_SN is set to a highest sequence number (SN) among SNs of the more than one RLC PDU having the poll;
- and
- transmitting, via the at least one transceiver, the L RLC PDUs in the transmission opportunity,
- wherein each of the L RLC PDUs contains either a not previously transmitted RLC service data unit (SDU) or an RLC SDU segment containing a not previously transmitted byte segment.
A processing device comprising:
- at least one processor;
- and
- at least one computer memory that is operably connectable to the at least one processor and that has stored thereon instructions which, when executed, cause the at least one processor to perform operations comprising:
- submitting L number of radio link control (RLC) PDUs to a medium access control (MAC) layer;
- setting a state variable POLL_SN based on the L RLC protocol data units (PDUs) that are submitted to the MAC layer for a transmission opportunity, where L is greater than 1;
- wherein the L RLC PDUs include more than one RLC PDU having a poll to trigger status reporting at a receiving device, and wherein the state variable POLL_SN is set to a highest sequence number (SN) among SNs of the more than one RLC PDU having the poll;
- and
- transmitting the L RLC PDUs in the transmission opportunity,
- wherein each of the L RLC PDUs contains either a not previously transmitted RLC service data unit (SDU) or an RLC SDU segment containing a not previously transmitted byte segment.
A method for transmitting protocol data units (PDUs) in a wireless communication system, the method comprising:
- submitting L number of radio link control (RLC) PDUs to a medium access control (MAC) layer;
- setting a state variable POLL_SN based on the L RLC PDUs that are submitted to the MAC layer for a transmission opportunity, where L is greater than 1;
- wherein the L RLC PDUs include more than one RLC PDU having a poll to trigger status reporting at a receiving device, and wherein the state variable POLL_SN is set to a highest sequence number (SN) among SNs of the more than one RLC PDU having the poll;
- and
- transmitting the L RLC PDUs in the transmission opportunity,
- wherein each of the L RLC PDUs contains either a not previously transmitted RLC service data unit (SDU) or an RLC SDU segment containing a not previously transmitted byte segment.
