Embodiment Construction

[0080] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0081] In the IAB scenario, there are the following definitions:

[0082] Host base station / node (English can be expressed as IAB donor / node): An anchor point connected to the core network with optical fibers, such as figure 2 DgNB in.

[0083] IAB node (English can be expressed as IAB node): no fiber connection to the core network, but can be backhauled through wireless links, and can provide access functions, such as figure 2 IAB 1 and IAB2 in . In the standardization research, the access function of the IAB node is called the DU function, and the backhaul function is called the MT function.

[0084] Parent node: the last hop node of an IAB node, such as figure 2 DgNB in ​​is the parent node of IAB 1.

[0085] Parent link: the link between an IAB node and its parent node.

[0086] Child node: the next hop node of an IAB node, such a...

Abstract

The invention discloses a resource allocation method and device, a first node, a second node and a storage medium. The method comprises the following steps that a first node determines a first resource of an access link of a second node, wherein the first resource is a resource for transmitting a synchronization signal / physical broadcast channel block (SSB), a return link exists between the firstnode and the second node, and the first node is a previous hop node of the second node; a second resource corresponding to a return link of the second node is allocated to the second node by using thedetermined first resource, and the second node is notified, wherein the second resource is different from the first resource, in the access link, the downlink sending time of the second node is aligned with the downlink sending time of a host node, and in the return link of the second node, the uplink and downlink sending time of the second node is aligned, and the uplink and downlink receiving time is aligned.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a resource allocation method, device, related equipment and storage medium. Background technique [0002] In 5G hotspot high-capacity scenarios, such as shopping malls, plazas, airports and other places, the transmission rate of downlink data can reach 300Mbps, the transmission rate of uplink data can reach 50Mbps, and the downlink capacity can reach 750Gbps / km 2 , the uplink capacity can reach 125Gbps / km 2 ; In order to support such a high transmission rate and capacity, large bandwidth and dense deployment are required, and high-frequency millimeter waves can meet this demand. [0003] However, due to the limited coverage of high-frequency millimeter waves, dense deployment is required. In order to reduce the dependence and cost on optical fibers, it is necessary to use Integrated Access and Backhaul (IAB, Integrated Access and Backhaul) technology, ...
