Embodiment Construction

[0072] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0073] In the embodiment of the present invention, in the case of semi-static TDD configuration, the HARQ timing indication manner from the downlink transmission unit to the corresponding uplink transmission unit is determined. Wherein, the indication manner may be high-layer signaling configuration, and specifically may be radio resource control RRC signaling.

Abstract

The embodiments of the present invention provide a timing relationship indication method, a timing relationship receiving method, a network side device and a terminal. According to the timing relationship indication method, the timing relationship receiving method, the network side device and the terminal of the invention, the indication information of a timing relationship set configured for eachdownlink transmission unit is sent to a terminal through high-layer signaling, wherein the timing relationship set comprises at least one timing relationship. An uplink scheduling time sequence and hybrid automatic repeat request (HARQ) time sequence indication mode during the 5G semi-static configuration of uplink and downlink sub-frames is provided, so that UE knows a time sequence from a downlink transmission unit to a corresponding uplink transmission unit.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an indication of a timing relationship, a receiving method, a network side device and a terminal. Background technique [0002] In a wireless frame of the TD-LTE system, there are 7 different configurations of uplink subframes, downlink subframes and special subframes. The direction of uplink and downlink subframes for each configuration is fixed. The TD-LTE system can meet the requirements of different proportions of uplink and downlink traffic. In addition, the minimum time length between PDSCH (Physical Downlink Shared Channel) and ACK / NACK feedback in LTE is fixed at 4ms, so the feedback timing from PDSCH to PUCCH (Physical Uplink Control Channel) can be determined according to different TDD uplink and downlink subframe configurations . [0003] In the design of 5G NR, due to the variety of service types, the fixed configuration in the LTE system cannot meet t...
