Problems solved by technology

[0004] When a terminal performs new transmission or retransmission through the HARQ process corresponding to a certain carrier, if there is no opportunity for uplink transmission on the carrier for a long time, the terminal needs to wait for a long time to perform new transmission or retransmission through the HARQ process, resulting in terminal The delay of the uplink service is too large, which affects the network performance

Abstract

Disclosed are an uplink HARQ transmission method and a communication device, and relate to the field of communications, capable of shortening the waiting time of uplink transmission of a terminal andimproving network performance. The uplink HARQ transmission method comprises the following steps: on a first uplink carrier, sending a first transmission block to access network equipment through a first HARQ process; and on a second uplink carrier, sending a second transmission block to the access network equipment through the first HARQ process, wherein the second transmission block and the first transmission block are transmitted in a time division multiplexing TDM mode.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular to an uplink HARQ transmission method and a communication device. Background technique [0002] Existing fourth generation (4 th generation, 4G) communication system and (5 th generation, 5G) communication system supports carrier aggregation technology (carrier aggregation, CA), that is, by aggregating multiple continuous or discontinuous carriers (component carrier, CC) into a larger bandwidth, network devices and terminals can simultaneously Receive and send data on multiple carriers for higher service rates. [0003] In a carrier aggregation scenario, only a hybrid automatic repeat request (HARQ) process corresponding to the carrier can be used for transmission on a certain carrier. For example, in a scenario where a 3.5GHz carrier and a 2.1GHz carrier are aggregated, the data initially transmitted on the 3.5GHz carrier through the HARQ process 1 can...
