Abstract
A media access control element (MAC CE) indicates a terminal device to enable or disable at least one hybrid automatic repeat request (HARQ) process, or the MAC CE requests a network device to enable or disable the at least one HARQ process. This provides a solution for dynamically controlling a HARQ function.
Claims11
A method comprising:
- determining whether a quality of a physical channel meets a preset channel quality requirement;
- generating a media access control protocol data unit (MAC PDU), wherein the MAC PDU comprises a MAC control element (CE), and the MAC CE requests a network device to enable at least one hybrid automatic repeat request (HARQ) process of a plurality of HARQ processes when the quality of the physical channel meets the preset channel quality requirement, or to disable at least one HARQ process of the plurality of HARQ processes when the quality of the physical channel does not meet the preset channel quality requirement, the enabling and disabling indicated by the MAC CE comprising one bit of a HARQ enabling indication and seven bits of a HARQ process index and a logical channel identifier (LCID) in a header field of the MAC CE being a reserved value that identifies a newly added MAC CE;
- and
- sending the MAC PDU.
1 more element
A communication device, comprising:
- at least one processor, the at least one processor is coupled to a non-transitory memory;
- wherein when reading and executing program code stored in the non-transitory memory, the at least one processor is configured to:
- determine whether a quality of a physical channel meets a preset channel quality requirement;
- generate a media access control protocol data unit (MAC PDU), wherein the MAC PDU comprises a MAC control element (CE), and the MAC CE requests a network device to enable at least one hybrid automatic repeat request (HARQ) process of a plurality of HARQ processes when the quality of the physical channel meets the preset channel quality requirement, or to disable at least one HARQ process of the plurality of HARQ processes when the quality of the physical channel does not meet the preset channel quality requirement, wherein the enabling and disabling indicated by the MAC CE comprises one bit of a HARQ enabling indication and seven bits of a HARQ process index and a logical channel identifier (LCID) in a header field of the MAC CE being a reserved value that identifies a newly added MAC CE;
- and
- send the MAC PDU.
