Description

Resource indication method and device, computer storage medium Technical field

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

Background technique

In the Long Term Evolution (LTE) system, the backhaul link between the base stations and the base station and the core network uses a wired connection, which brings greater deployment difficulty and higher network for the operator. Cost, in order to solve the above problems, the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) initiated research on wireless relay technology in the evolution stage of LTE-A (LTE-A) to provide wireless backhaul chains. Road solution.

The RN (Relay Node) is connected to the eNB (evolved NodeB) cell to which it belongs. The eNB is called the Donor cell. The eNB to which the relay node belongs is called the Donor eNB (referred to as the DeNB). The network structure of the incoming relay node is shown in Figure 1, which includes three wireless links:

1. A backhaul link between the RN and the DeNB;

2. An access link between an end user equipment (UE, User Equipment) and an RN (Access link);

3. Direct link between the UE and the eNB.

In the LTE-A relay system, the access link and the backhaul link perform resource multiplexing in a time division manner. In the access link, as shown in FIG. 2, the RN configures some fixed subframes (such as a Multicast-Broadcast Single Frequency Network (MBSFN) subframe), and divides the X in these subframes. In addition to the symbols (such as X=1, 2), the RN does not transmit or receive data on the access link, and the DeNB can transmit or receive data on the symbols following the subframe, thereby implementing the access link and the backhaul. Resource reuse of links.

In the new radio (NR, New Radio) system, the slot format is more flexible, and each slot can include a downlink symbol (DL), a flexible symbol (Flexible), an uplink symbol (UL), and does not need to consider the Rel-8. The compatibility problem of the terminal, so it is not necessary to implement the resource multiplexing of the backhaul link by configuring the MBSFN subframe on the access link, and the access link and the backhaul link time slot or symbol level can be implemented in the NR system. Resource reuse. In the resource multiplexing of the symbol level, some symbols in one slot are reserved by the access link for the backhaul link, so the backhaul link can only use some symbols in the symbol, how to indicate The slot format of this slot is a problem that needs to be solved.
