Description

Method and apparatus in a node for wireless communication

Technical Field

The present application relates to transmission methods and apparatuses in wireless communication systems, and more particularly, to transmission schemes and apparatuses for reduced capability devices in wireless communications.

Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided on the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started on the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

In the new air interface technology, the application of the internet of things is an important component. Although some new features have been introduced in Release 15 and 16 versions (Release 16) to support different internet of things application scenarios, such as Ultra-reliable low latency communications (URLLC, ultra-reliable and Low Latency Communications) and industrial physical networks (IIoT, industrial Internet of Things), standard support is still required for other application scenarios, such as wearable devices, surveillance videos, etc. Based on the above background, SI (Study Item) passed the reduced capability (RedCap, reduced Capability) (also referred to as NR-Lite in the early stage) at the 3gpp ran#86 full meeting, and the Study was started at Release 17 (Release 17).

Disclosure of Invention

Reducing radio frequency bandwidth is one of the effective ways to reduce the complexity of user equipment. However, due to the reduction of the radio frequency Bandwidth of the user equipment, the existing Bandwidth Part (BWP) based resource allocation method may not be directly reused.

It should be noted that, in the description of the present application, only a user equipment with a narrow bandwidth (such as a RedCap) is taken as a typical application scenario or example; the method and the device are also applicable to other scenes with limited receiving or transmitting bandwidth, which face similar problems (for example, in the scene of supporting larger carrier bandwidth, user equipment supporting the existing bandwidth may also face similar problems), and similar technical effects can be achieved. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to the RedCap scenario) also helps to reduce hardware complexity and cost.
