Embodiment Construction

[0121] The concepts discussed in further detail below focus on wireless relay operations on top of the NR frame structure (also known as self-backhaul, ie Integrated Access and Backhaul IAB). Furthermore, the embodiments, as discussed below, focus on time division duplex (TDD) relay scenarios, where relays are configured to support wireless relay operations. In other embodiments, it is discussed where radio resources can be allocated in a flexible manner between the backhaul link and the access link and between the uplink (UL) and downlink (DL) while minimizing access Scenarios for link and backhaul link delays. In some embodiments, frequency division duplex (FDD) relay scenarios can be envisioned, where the following example can be modified such that the radio resource slots allocated between uplink and downlink transmissions are in the frequency domain instead of time domains are separated.

[0122] Before explaining the examples in detail, refer to Figures 1 to 2 Some g...

Abstract

An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured, with the at least oneprocessor, to cause the apparatus at least to support for a determined period at least one hop within a multi-hop self-backhaul communications, wherein the determined period comprises: a first part within which information for controlling dynamic allocation between backhaul and access links within resource slots is passed between the apparatus and at least one further apparatus in the multi-hop self-backhaul communications; and a second part within which a dynamic slot pattern is implemented based on the information for controlling dynamic allocation between backhaul and access links within resource slots is passed between the apparatus and at least one further apparatus in the multi-hop self-backhaul communications.

Description

technical field [0001] The present application relates to a method, apparatus, system and computer program, and in particular but not exclusively to methods and apparatus for wireless backhaul in 5G New Radio communication networks. Background technique [0002] A communication system can be viewed as a facility that enables two or more entities (such as user terminals, base stations / access points, and / or other nodes) to ) between communication sessions. A communication system may be provided eg by means of a communication network and one or more compatible communication devices. A communication session may include, for example, data communications for carrying communications such as voice, electronic mail (email), text messages, multimedia and / or content data, and the like. Non-limiting examples of services provided include two-way or multi-way calls, data communication or multimedia services, and access to data network systems such as the Internet. [0003] In a wireles...
