Embodiment 1

[0137] An embodiment of the present invention provides a CSI transmission method, which is specifically applied in such as figure 2 shown on the UE, as image 3 shown, including:

[0138] S301. The UE receives downlink data sent by an access network device.

[0139] S302. The UE determines an uplink subframe for sending feedback information of the downlink data, wherein the first set of downlink subframes associated with the uplink subframe includes a first subset and a second subset, and the The first subset is a proper subset of the second subset.

[0140] S303. The UE determines a channel resource for sending the feedback information, wherein the channel resource includes a first uplink channel resource or a second uplink channel resource, and the first uplink channel resource is a p-codebook size format channel resources, the second uplink channel resource is the resource of the q codebook size format channel, q>p, q≥q1, p≥p1, p1 is the codebook size of the feedback in...

Embodiment 2

[0235] An embodiment of the present invention provides a CSI transmission method, which is specifically applied to access network equipment, as follows Figure 6 As shown, the methods include:

[0236] S601. The access network device sends downlink data to the UE.

[0237] S602. The access network device determines an uplink subframe for receiving feedback information of the downlink data, wherein the first set of downlink subframes associated with the uplink subframe includes a first subset and a second subset , the first subset is a proper subset of the second subset.

[0238] Specifically, for the relevant description of the feedback information in this embodiment of the present invention, reference may be made to Embodiment 1, and details are not repeated here.

[0239] Specifically, the access network device may determine an uplink subframe for receiving the feedback information according to preconfiguration. For example, the uplink subframe used to receive the feedbac...

Embodiment 3

[0284] An embodiment of the present invention provides a UE900, such as Figure 9 As shown, the UE900 includes: a receiving module 901, a processing module 902, and a sending module 903.

[0285] The receiving module 901 is configured to receive downlink data sent by an access network device.

[0286] The processing module 902 is configured to determine an uplink subframe for sending feedback information of the downlink data, wherein the first set of downlink subframes associated with the uplink subframe includes a first subset and a second subset , the first subset is a proper subset of the second subset;

Abstract

Embodiments of the present invention provide a channel state information transmission method, user equipment, and access network equipment, so as to at least solve the problem that simultaneous transmission of multiple CSIs cannot be realized in the prior art. The method includes: the UE receives the downlink data sent by the access network device; the UE determines the uplink subframe used to send the feedback information of the downlink data, wherein the first set of downlink subframes associated with the uplink subframe includes the first subset and the second subset Two subsets, the first subset is a proper subset of the second subset; and the UE determines channel resources for sending feedback information, where the channel resources include the first uplink channel resource or the second uplink channel resource; if the uplink subframe The UE is configured to send r shares of CSI, the codebook size of the feedback information corresponds to the first subset, and the channel resource determined by the UE is the second uplink channel resource, and the UE sends the feedback information and r shares of CSI on the second uplink channel resource t parts of CSI in CSI.

Description

technical field [0001] The present invention relates to the communication field, and in particular to a channel state information (Channel State Information, CSI for short) transmission method, user equipment (User Equipment, UE for short), and access network equipment. Background technique [0002] With the development of mobile communication technology, the future mobile communication system will provide higher data rate transmission and wider service coverage. As a common transmission mode, carrier aggregation (Carrier Aggregation, CA for short) is more and more widely used in the field of mobile communication. The idea of ​​CA is: the access network device configures and provides multiple carriers for uplink and downlink communication to a UE that supports carrier aggregation, so as to support higher data rate transmission. Wherein, the carrier includes a primary carrier and a secondary carrier. [0003] In the existing Long Term Evolution (abbreviation: LTE) CA system...
