Description

Resource indication method and device, and computer storage medium

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for resource indication, and a computer storage medium.

In the Long Term Evolution (LTE) system, the backhaul link between base stations and between the base station and the core network uses a wired connection method, which brings greater deployment difficulties and higher Cost of network deployment. In order to solve the above problems, the 3rd Generation Partnership Project (3GPP) initiated research on wireless relay technology during the LTE-A (LTE-Advanced) standardization phase to provide Solutions for wireless backhaul links.

A relay node (RN, Relay Node) is wirelessly connected to its evolved Node B (eNB) area. The home eNB area is called a Donor cell, and the eNB to which the relay node belongs is called a Donor eNB (DeNB for short). ), The network structure of the relay node is shown in Figure 1, which includes 3 wireless links:
1. Backhaul link between RN and DeNB;
2. Access link (Access link) between end user equipment (UE, User Equipment) and RN;
3. Direct link between UE and eNB.

In the LTE-A relay system, the access link and the backhaul link use time division for resource multiplexing. In the access link, as shown in FIG. 2, the RN is configured with some fixed subframes (such as a Multicast-Broadcast Single Frequency Network (MBSFN) subframe), and the first X is divided in these subframes. In addition to the number of symbols (such as X = 1, 2), the RN does not send or receive data on the access link. The DeNB can send or receive data on the symbols behind the subframe, so as to achieve the access link and the backhaul chain. Road resource reuse.

In the new air interface (NR, New Radio) system, the slot format is more flexible. Each slot can contain downlink symbols (DL), flexible symbols (UL), and uplink symbols (UL). 8 terminal compatibility issues, so there is no need to configure MBSFN subframes on the access link to achieve resource reuse with the backhaul link. In the NR system, access link and backhaul link time slots or Symbol-level resource reuse. Among them, in symbol-level resource multiplexing, some symbols in a time slot are reserved by the access link for use by the backhaul link, so the backhaul link can only use some of the symbols.
