Embodiment Construction

[0066] The embodiments of the present application are applicable to a cellular system with a relay device, including scenarios supporting single-hop and multi-hop relays, where the backhaul link and the access link use the same frequency spectrum resource.

[0067] In a multi-hop relay network, a relay device may be connected to a donor base station (for example, DgNB or DeNB), and may also be connected to another relay device. In order to distinguish the backhaul link between this relay device and the relay device, the relay device in the control role (or, with fewer hops with the donor base station) is called the superior relay device, and the relay device in the controlled role is called the superior relay device. The relay device that controls the role (or has a large number of hops with the donor base station) is called a subordinate relay device. Wherein, the backhaul link is a link between the donor base station or the upper-level relay device and the lower-level relay ...

Abstract

The invention discloses a power control method and device, and the method comprises the steps that a first node receives first information sent by a second node, the first information is used for determining first sending power, and the first sending power is power adopted when the first node sends downlink information to the second node through a first link, the first link is a link between the first node and the second node, and the first node is superior equipment of the second node; the first node determines a first transmission power according to the first information. Therefore, the first node determines the first transmission power according to the first information, and the first transmission power is adopted when the downlink information is transmitted to the second node through the first link, so that the interference among the signals received by the second node can be reduced.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a power control method and device. Background technique [0002] The 4G Long Term Evolution (LTE) system introduces the relaying technology (Relaying), by deploying the relay node (Relay Node, RN) in the network to forward the data between the base station and the terminal equipment, so as to enhance the network capacity And to solve the purpose of coverage blind spots, its simple network topology such as figure 1 shown. Wherein, the link between the donor base station (DonoreNB, DeNB) and the RN is called a backhaul link, and the link between the RN and the terminal equipment is called an access link. [0003] In the 5G New Radio (NR) system, the relay technology will still be supported. NR introduces the concept of Integrated Access and Backhaul (IAB). Compared with relaying in LTE, IAB needs to support resource sharing of access link and backha...
