Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] figure 1 The system architecture or scenario diagram applied to the embodiments of the present application, such as figure 1 As shown, a base station (Basestation) and UE1-UE6 form a communication system. In this communication system, the Basestation sends one or more of system information, random access response (RAR) messages and paging (Paging) messages to One or more UEs among UE1 to UE6. In addition, UE4 to UE6 may also ...

Abstract

The invention discloses a method and device for transmitting a control channel and a communication node. The method comprises the following steps: sending a first message to user equipment (UE), wherein the first message includes a set of control channel configuration information; determining control channel configuration information used in transmission of the control channel for the UE according to the control channel configuration information set; and transmitting the control channel according to the control channel configuration information used in the transmission of the control channel determined for the UE. The control channel configuration information used in the transmission of the control channel can be determined for the UE, and the control channel is transmitted (received and sent) according to the control channel configuration information, so that the UE can directly transmit the control channel corresponding to the control channel configuration information during transmission of the control channel, and the detection complexity of the UE is lowered.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular, to a method, an apparatus and a communication node for control channel transmission. Background technique [0002] In the existing communication system, the control channel is a channel for transmitting control information to the user equipment. For example, the control channel may be a control channel that schedules dedicated data for the UE, and / or common data for the UE (for example, the common data is system information). , or random access response message, or paging message) control channel. For example, the control channel is an EPDCCH or a control channel (eg, M-PDCCH) for machine type communication MTC UEs. [0003] In order to receive the control information transmitted by the control channel, the UE needs to obtain the configuration information of the control channel in advance. In the prior art, when the UE obtains its own configuration information f...
