The scheme of the invention provides an uplink scheduling time sequence and a hybrid automatic repeat request (HARQ) time sequence indication mode in a 5G semi-static configuration uplink and downlink subframe scene, so that the UE can clearly determine the time sequence from a downlink transmission unit to a corresponding uplink transmission unit.

Description

Timing relation indicating and receiving method, network side equipment and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a timing relationship indicating and receiving method, a network side device, and a terminal.
Background
In a radio frame of the TD-LTE system, 7 different configurations are arranged for an uplink subframe, a downlink subframe and a special subframe, the direction of the uplink subframe and the downlink subframe of each configuration is fixed, and the TD-LTE system can meet the requirements of different uplink and downlink traffic ratios by adjusting the ratio of the uplink subframe to the downlink subframe. In addition, the minimum time length between PDSCH (physical downlink shared channel) to ACK/NACK feedback in LTE is fixed to 4ms, so feedback timing of PDSCH to PUCCH (physical uplink control channel) can be determined according to different TDD uplink and downlink subframe configurations.
In the design of 5G NR, because of the variety of service types, the fixed configuration in the LTE system cannot meet the requirements of various services, and the fully dynamic configuration flexibility is high, but huge signaling overhead is caused. Therefore, a semi-static configuration of a part of uplink and downlink transmission directions for a period of time (such as an initial access phase) is required, so as to ensure the reliability of data transmission. In addition, in the design of NR, different UEs have different minimum HARQ (hybrid automatic repeat request) processing capabilities, and the time interval from the downlink transmission unit to the uplink transmission unit is variable, so that the HARQ timing in NR needs to be indicated to the terminal, and a specific indication needs to be designed.
In the LTE system, a feedback subframe is defined when the uplink and downlink subframes transmit the traffic channel, and if PDSCH transmission is detected on the downlink subframe n-k, the UE replies ACK/NACK on the uplink subframe n, where the timing is defined based on the determined uplink and downlink subframe ratio and the determined UE processing capability. For the case of semi-static TDD configuration, the terminal cannot determine the timing of the downlink transmission unit to the corresponding uplink transmission unit.
