Embodiment Construction

[0037] As mentioned in the background, in the existing inter-cell interference coordination scheme, if the TDD configurations of neighboring cells and this cell are different, special uplink subframes or other similar configurations (such as configured MBSFN or ABS The set contains uplink subframes), but after the introduction of the above configurations, the prior art does not provide a corresponding processing solution for the behavior of the terminal device in the uplink subframes corresponding to the above configurations.

[0038] The technical solution proposed by the embodiment of the present invention stipulates that the terminal equipment prohibits data transmission in the special uplink subframe, so as to avoid the interference caused by the data transmission of the UE in the special uplink subframe to the downlink data transmission of adjacent cells.

[0039] Such as Figure 4 As shown, it is a schematic flowchart of a processing method for uplink data transmission p...

Abstract

The embodiment of the invention discloses a method and equipment for processing uplink data transmission. By the technical scheme of the embodiment of the invention, the method comprises the following steps that: terminal equipment can accurately determine a special uplink sub-frame allocated by a base station, and the terminal equipment can stop the uplink data transmission on the special uplink sub-frame so as to avoid interference with downlink data transmission of cells caused by performing uplink data transmission on the special uplink sub-frame by the terminal equipment, and ensure the communication quality of the system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a processing method and equipment for uplink data transmission. Background technique [0002] In a heterogeneous network, there are various types of low-power nodes such as HeNB (Home evolved Node B, home evolved base station), PeNB (Pico evolved Node B, micro cell base station), Relay (relay node) and so on. Due to the overlapping coverage and power imbalance between different types of base stations, the interference situation in the heterogeneous network becomes very complicated, especially for the case of single carrier, the base stations that interfere with each other use the same The interference situation on each channel will be very serious when resources are used. [0003] Such as figure 1 As shown in , it is a schematic diagram of an interference scenario in a heterogeneous network in the prior art. [0004] In order to reduce mutual interference, many ...
