Embodiment 1

[0050] figure 1 It is a flowchart of a method executed by a base station according to an embodiment of the present invention.

[0051] Step 101: The base station sends a configuration message, which includes the PUCCH reference cell configuration information of the serving cell. For example, the base station may send the PUCCH reference cell configuration information of the serving cell when the serving cell is added or modified. The PUCCH reference cell configuration information may indicate the cell to which the PUCCH used for UCI transmission by the serving cell belongs. The implementation of the PUCCH reference cell in the 3GPP standard protocol can be seen in the examples given in the following embodiments 4-7, but it is not limited thereto.

[0052] Step 102: The base station receives the uplink control information UCI of the serving cell on the corresponding PUCCH according to the PUCCH reference cell configuration information of the configured serving cell.

[0053] The fol...

Embodiment 2

[0065] Figure 4 It is a flowchart of a method executed by a UE according to an embodiment of the present invention. This embodiment provides a method for the UE to send the UCI of the serving cell on the PUCCH channel of the corresponding reference cell according to the PUCCH reference cell configuration information of the serving cell configured by the eNB. In this embodiment, the serving cell refers to SCell.

[0066] Step 401: The UE receives the PUCCH configuration information of the SCell and / or the PUCCH reference cell configuration information. Among them, the PUCCH configuration information of the SCell indicates that the PUCCH is configured on the SCell; the PUCCH reference cell configuration information of the SCell is as described above.

[0067] Step 402: The UE triggers UCI reporting of one or more SCells.

[0068] Step 403: The UE judges whether the SCell is a reference cell. If yes, go to step 405c; otherwise, go to step 404. Specifically, in this step, the UE can...

Embodiment 3

[0075] Figure 5 It is a flowchart of a method executed by a UE according to an embodiment of the present invention. This embodiment provides a method for the UE to send the UCI of the serving cell on the PUCCH channel of the corresponding reference cell according to the PUCCH reference cell configuration information of the serving cell configured by the eNB. In this embodiment, the serving cell may be a PCell or an SCell. That is, compared with Embodiment 2, a step is added in this embodiment to determine whether the serving cell is a PCell.

[0076] Step 501: The UE receives the PUCCH configuration information of the serving cell and / or the PUCCH reference cell configuration information. Wherein, the PUCCH configuration information of the serving cell indicates that the PUCCH is configured on the serving cell; the PUCCH reference cell configuration information of the serving cell is as described above.

[0077] Step 502: The UE triggers UCI reporting of one or more serving cells...

Abstract

The present invention provides a method for configuring a serving cell group, a base station and a user equipment. The method includes: a base station sends configuration information of a serving cell group to a user equipment with carrier aggregation capability, where the configuration information of the serving cell group indicates a reference cell used for transmitting uplink control information of the serving cell. The present invention enables the base station to flexibly configure multiple PUCCH reference cells, and configure different PUCCH reference cells according to different cell loads.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology. More specifically, the present invention relates to a resource configuration method for communication between devices and a base station and user equipment. Background technique [0002] With the development of mobile communication and the diversification of services, higher and higher requirements are put forward for the transmission rate of the communication system. Carrier Aggregation (CA) technology has been introduced in 3GPP Release 10 and Release 11 to improve the downlink and uplink rates of the system. That is, User Equipment (UE) can be configured with multiple carriers at the same time, and can transmit and receive on these multiple carriers at the same time. Compared with the previous single carrier transmission, this greatly improves the transmission rate and resource utilization. rate. [0003] In 3GPP Release 10 and Release 11, a serving base station (eNB) confi...
