Embodiment 1
[0093] As described below, an embodiment of the present invention provides a downlink data control method.
[0094] The downlink data control method provided in this embodiment can generally be implemented by a base station in a mobile communication system, and is applicable to various 4G systems and 5G systems.
[0095] Through the downlink data control method provided in this embodiment, the base station sends scheduling information related to each UE residing in the cell, so that each UE can detect and judge whether the UE is scheduled accordingly.
[0096] Through the downlink data monitoring method provided in the third embodiment of the present invention, the UE detects the first type of control channel resource units in the channel in real time, and judges whether the UE is scheduled accordingly.
[0097] refer to figure 1 The flow chart of the downlink data control method is shown in detail below through specific steps:
[0098] S101, setting instruction information....
Embodiment 2
[0124] As described below, an embodiment of the present invention provides a device for controlling downlink data.
[0125] refer to figure 2 The structural block diagram of the downlink data control device is shown.
[0126] The downlink data control device includes: a setting unit 201, a first processing unit 202 and a sending unit 203; wherein the main functions of each unit are as follows:
[0127]A setting unit 201, configured to set indication information, the indication information indicating whether there is currently scheduling information;
[0128] The first processing unit 202 is configured to, after the setting unit 201 performs the operation, perform first processing on the indication information related to the first identifier of the UE, where the first identifier of the UE is that the UE is in a cell or a beam The unique identifier of the instruction information is carried by the first type of control channel resource unit after the first processing, and the ...
Embodiment 3
[0145] As described below, an embodiment of the present invention provides a base station.
[0146] The difference from the prior art is that the base station includes a downlink data control device as provided in the embodiment of the present invention. Therefore, in the process of sending scheduling information to each UE in the cell, the base station of this scheme separates the UE's first identity from the DCI independently, that is, it is no longer mixed with other control information in the DCI, and the first type of control resource unit occupies The number of bits is very small, and the number of REGs used when sending in the channel is also small, which reduces the complexity of UE detection and can reduce the power consumed by the UE in the process of detecting scheduling information.
[0147] In a specific implementation, the base station may be a base station of a 4G or 5G mobile communication system.
