Embodiment Construction

[0042] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] The UE control information in the present invention refers to: the control information included in the existing UE control signaling.

[0044] The basic idea of ​​the present invention is to transmit control information of a group of UEs in one control signaling, thereby saving control channel transmission.

[0045] Specifically, the method for sending UE control information in the present invention includes: the base station divides an area SPA semi-persistently in the physical resources of the subframe, sets the area SPA to transmit control signaling serving a group of UEs, and broadcasts or signals The UEs under the base station are notified of the divided area SPA and corresponding settings; the base station uses the semi-persistently divided area SPA to ...

Abstract

The invention provides a control information sending method for UE (user equipment). The method comprises the following steps of semi-continuously dividing a regional SPA (scratch pad area) in physical resource of a subframe by a base station, setting the regional SPA to transfer a control signalling serving a group of UE of the base station, and notifying the divided regional SPA and the corresponding settings to the UE of the base station through broadcasting or signaling, wherein the control signalling serving one group of the UE is used for carrying the control information of the group of UE; enabling the control information of the group of the UE to be carried in the control signalling of the group of the UE by the base station according to the above settings, and performing transmission by utilizing the semi-continuously divided regional SPA. By adopting the method provided by the invention, the cost of a control channel can be saved.

Description

technical field [0001] The present invention relates to a control channel technology of a communication system, in particular to a method for sending control information of a UE. Background technique [0002] In the current wireless communication systems including OFDM / OFDMA, the time-frequency resources of the control channel are relatively fixed, which is convenient for the UE to obtain; there are also some designs that place the control information completely dynamically, so that the control information and service data can be fully mixed and transmitted. Dynamics also increase the complexity of signaling and computation complexity. [0003] In the existing OFDM / OFDMA system, the control channel design is suitable for relatively flexible data service data, but the signaling overhead is relatively large; and with the development of the mobile Internet, short data such as microblog, twitter, game interaction, and instant messages With the emergence of a large number of ser...
