Embodiment approach

[0166] Embodiment A: In this embodiment, the channel quality information of the first reference signal resource group is carried in the first information, and the channel quality information of the second reference signal resource group is carried in the second information.

[0167] In this embodiment, in the above-mentioned first information, the quality information of the first reference signal resource is adjacent to the identifier of a first reference signal resource, and the quality information of the first reference signal resource is adjacent to is the identifier of the next first reference signal resource; in the above-mentioned second information, what is adjacent to the identifier of a third reference signal resource is padding information, and what is adjacent to the identifier of a second reference signal resource is the one For the quality information of the second reference signal resource, if the one third reference signal resource is not the last reference signa...

Abstract

The present application provides a method and device for transmitting channel quality information. The method includes: the terminal device receives the reference signal sent by the access network device; the terminal device sends channel quality information of at least two reference signal resource groups to the access network device; the first reference signal resource in the at least two reference signal resource groups The channel quality information of the group includes identifiers of N1 reference signal resources and quality information of N1 reference signal resources; the channel quality information of the second reference signal resource group in at least two reference signal resource groups includes identifiers of N2 reference signal resources , the quality information of N3 reference signal resources, N4 of the identifiers of N2 reference signal resources are the same as the identifiers of N1 reference signal resources, N3=N2-N4; each reference signal resource in the identifiers of N3 reference signal resources The identifiers of are different from the identifiers of the N1 reference signal resources. The method improves the decoding efficiency of the access network equipment.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a method and device for transmitting channel quality information. Background technique [0002] With the emergence of smart terminals, especially video services, the current spectrum resources have been difficult to meet the explosive growth of users' demand for capacity. High-frequency frequency bands with larger available bandwidth, especially millimeter-wave frequency bands, are increasingly becoming candidates for next-generation communication systems. band. On the other hand, in the scenario where the current communication system uses multi-antenna technology to improve system capacity and coverage, the use of high-frequency frequency bands can also greatly reduce the size of the multi-antenna configuration. However, unlike the working frequency bands of existing Long Term Evolution (LTE) and other systems, high frequency bands will lead to greater path loss, espe...
