Embodiment Construction

[0108] In the present application, "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character " / " generally indicates that the contextual objects are an "or" relationship.

[0109] It should be understood that although the terms first and second may be used to describe REGs in this application, these REGs should not be limited to these terms. These terms are only used to distinguish REGs from one another. For example, without departing from the scope of the embodiments of the present invention, the first REG may also be called the second REG, and similarly, the second REG may also be called the first REG.

Abstract

The present application provides a method for sending a control channel, a terminal device, and a network device. The method includes: the network device determines a set of control resources; wherein, the set of control resources is a set of time-frequency resources that are allowed to send control channels on downlink transmission resources, and the set of control resources The size of the set is M times N, and N is the number of control channel basic units included in a control channel element; both the N and the M are positive integers greater than or equal to 1; the network device on the control resource set, The control information carried on the control channel is sent to the terminal device. The method for sending the control channel, the terminal device, and the network device provided in this application set the control resource set so that the network device can send the control information carried on the control channel to the terminal device on the control resource set, so that the terminal device The transmitted control information can be blindly detected only on the set of control resources, which improves the efficiency of blind detection of the control channel by the terminal equipment.

Description

technical field [0001] The present application relates to communication technology, and in particular to a method for sending a control channel, a terminal device and a network device. Background technique [0002] In the New Radio (NR) standard of the 5G communication system, downlink transmission resources are divided into a control area and a data area. Among them, the control area is used to transmit control channels, and the data area is used to transmit data channels. The control information carried by the control channel includes the position in the frequency domain of the resource block (Resource Block, RB) used for indicating the data channel used in the data region, and the data channel is used to carry downlink data or uplink data. [0003] In order to improve the efficiency of blind detection of the control channel by the terminal equipment, the NR standard proposes the concept of a control resource set (control resource set). That is, one or more control resou...
