Embodiment 1

[0064] image 3 It shows a schematic diagram of sending uplink and downlink configuration information to a DRX terminal according to an embodiment of the present invention.

[0065] Such as image 3 As shown, when there is a terminal in the DRX state in the cell, because it only wakes up and receives information in a fixed time interval, and remains dormant in other time intervals, it may cause it to be unable to normally receive the above public control signal. make. In order to prevent the terminal in the DRX state from not receiving the public control signaling, missing the configuration of the uplink and downlink parameters, and causing transmission confusion and cross interference, the following operations can be performed on the terminal in the DRX state:

[0066] The base station generates dedicated control signaling, the dedicated control signaling includes the uplink and downlink configuration information, and places the dedicated control signaling in the dedicated ...

Embodiment 2

[0071] For terminals in the DRX state in the cell, other methods can also be used to ensure that they receive the corresponding uplink and downlink configuration information, combined below Figure 4 In detail, among them, Figure 4 It shows a schematic diagram of sending uplink and downlink configuration information to a DRX terminal according to another embodiment of the present invention.

[0072] Base station side: the base station sends uplink and downlink configuration information and other information respectively within a preset time interval.

[0073] DRX terminal side: the DRX terminal alternates between the normal state and the DRX state according to the configured cycle.

[0074] When no special coordination is performed on the DRX terminal, the time window for the DRX terminal to switch from the DRX state to the normal state may not match the time window for the base station to send uplink and downlink configuration information, resulting in the terminal being un...

Abstract

The invention provides a control signal transmission method. The control signal transmission method comprises the steps that a base station generates public control signals which comprise uplink and downlink configuration information, and the public control signals are put in a public searching space; the public control signals are sent. The invention further provides a base station. By means of the technical scheme, terminals in a cell can be made to obtain the uplink and downlink configuration information from the public searching space directly, the uplink and downlink configuration information dose not need to be sent to the terminals respectively, and the control signal transmission method and the base station are beneficial to reducing the number of sending times of the signals and the using of control channels.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, to a method for transmitting control signaling and a base station. Background technique [0002] In order to solve the problem of asymmetric uplink and downlink services in the TDD (Time Division Duplex) system, seven DL-UL (downlink-uplink) subframe configuration methods were designed in 3GPP Rel-8, such as figure 1 As shown, they are Configuration (configuration) 0 to configuration 6, and different configurations have different numbers of DL and UL subframes, that is, the number of special subframes 102, uplink subframes 104 and downlink subframes 106 included is different , to cope with different service requirements of the TDD-LTE system. [0003] Studies in related technologies have shown that rapidly changing uplink and downlink configurations according to user service requirements in the same geographical area can bring about a large throughput gain. ...
