Methods and device for indicating and reporting frequency bands supported by terminal

Abstract

The invention discloses a method for indicating frequency bands supported by a terminal, which comprises the following steps: setting pointers for extended frequency bands one by one, and using an aggregate of the pointers to indicate an extended frequency band currently supported by the terminal. The invention also discloses a method for reporting the frequency bands supported by the terminal, which comprises the following steps: setting enumerative pointers for all combination modes of the prior frequency band, and selecting an enumerative pointer for indication according to the prior frequency band currently supported by the terminal; setting pointers for extended frequency bands one by one, and using an aggregate of the pointers to indicate an extended frequency band currently supported by the terminal; and inserting the frequency pointer supported by the terminal into a wireless frequency band information unit, and reporting to a system side. The invention also discloses a device for realizing the two methods. The invention has strong expandability, has small modification on a protocol and is compatible with indicating and reporting modes of the prior frequency band.

Description

technical field [0001] The present invention relates to a frequency band indication and reporting technology supported by a terminal, more precisely, a method and device for indicating a frequency band supported by a terminal, and a method and device for reporting a frequency band supported by a terminal. Background technique [0002] In the existing Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system, terminals that support UTRA (Universal Telecommunication Radio Access) TDD mode can better support 3G networks, mobile TV, location services, etc. Function, terminals supporting UTRA TDD mode support multiple frequency bands. As a capability of the terminal, the terminal needs to report the supported frequency band to the network side, so that the network can allocate appropriate network resources to the terminal according to the capability of the terminal. At present, for a terminal supporting the...

AI Technical Summary

Problems solved by technology

It is foreseeable that the available frequency bands of the TD-SCDMA system will continue to increase, and the method of enumerating and indicating terminal capabilities will become complicated with the increase of frequency bands, resulting in a large protocol, and the enumeration method is not suitable In the case of too many frequency bands, every time a new frequency band is added, the corresponding relationship between the pointer in the protocol and the terminal support capability will be greatly adjusted, and the scalability is very poor.
