Problems solved by technology

[0004] However, the TDM scheduling mechanism is only applicable to E-DCH data transmission. If the DCH (Dedicated Channel, dedicated channel) voice data sent by the UE is not affected by the TDM scheduling mechanism
Therefore, when the base station does not schedule a UE to send E-DCH data, the UE can still send DCH voice data, which may cause interference to other UEs and reduce the performance of the TDM scheduling mechanism

Abstract

The embodiment of the invention provides a data sending method, an apparatus, a base station and a user's device. The method applied in the base station includes detecting the uplink interference situation of a cell, determining whether the uplink interference situation satisfies the preset interference scope or not, and if yes, sending a first control signal to instruct the user's device to start a time-division multiplex transmission mode which indicates employing a time-division mode to send DCH data on unlike carrier frequency. In this way, any user's device can send DCH data without changing a conventional network structure based on the time-division multiplex transmission mode when other user's devices do not send data. Accordingly, other user's devices may not send data when any one user's device sends DCH data based on the time-division multiplex transmission mode, thereby minimizing the probability of interference when user's devices send data.

Description

technical field [0001] The invention belongs to the technical field of voice communication, and in particular relates to a data sending method, device, base station and user equipment. Background technique [0002] Traditional HSUPA (High Speed ​​Uplink Packet Access) data uses scrambling codes to distinguish UEs (User Equipment, user equipment). When multiple UEs perform HSUPA transmission at the same time, they send E-DCH (Enhanced Dedicated Channel, enhanced Dedicated channel) data, because the scrambling codes are not orthogonal to each other, the E-DCH data sent by each UE will cause interference to other UEs, reducing the system throughput. [0003] To solve this problem, a TDM (Time Division Multiple, Time Division Multiplexing) scheduling mechanism is introduced for E-DCH data transmission. The TDM scheduling mechanism divides uplink air interface resources by time. Within a time resource, only a few or even one UE can send E-DCH data uplink, which can prevent multi...
