Description

Method and device used in wireless communication node

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for a reduced capability device in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of multiple application scenarios, a New air interface technology (NR, New Radio) (or 5G) is determined to be studied in 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 guilds, and standardization Work on NR starts after passing through WI (Work Item) of the New air interface technology (NR, New Radio) in 3GPP RAN #75 guilds.

In a 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 (Release 15) and Release 16 (Release 16) to support different Internet of Things application scenarios, such as Ultra-reliable Low-Latency Communications (URLLC) and Industrial physical networks (IIoT), standard support is still required for some other application scenarios, such as wearable devices, surveillance videos, etc. Based on the above background, the SI (Study Item) of Reduced Capability (Reduced Capability), also referred to as NR-Lite at the previous stage, was passed through at 3GPP RAN #86 at the next global meeting, and the Study work was started at Release 17 (Release 17).

Disclosure of Invention

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

The present application discloses a solution to the problem in narrow radio frequency bandwidth scenarios, such as red cap. It should be noted that in the description of the present application, only a narrow bandwidth user equipment (such as a RedCap) is taken as a typical application scenario or example; the present application is also applicable to other scenarios in which the receiving or transmitting bandwidth is limited and faces similar problems (for example, in a scenario in which a larger carrier bandwidth is supported, a user equipment supporting the existing bandwidth may also face similar problems), and may also achieve similar technical effects. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to a RedCap scenario) also helps to reduce hardware complexity and cost. Without conflict, embodiments and features of embodiments in a first node device of the present application may apply to a second node device and vice versa.
