Problems solved by technology

[0003] But in the wireless network system using D-TDD technology, such as figure 1 As shown, there is same-frequency cross-interference between neighboring nodes in the wireless network system, and the same-frequency cross-interference specifically includes adjacent cell same-frequency base stations (such as figure 1 The evolved node eNB2) transmits downlink to the base station of the cell (such as figure 1 eNB1) in the uplink received interference, and adjacent cell user equipment UE (such as figure 1 UE1) transmits uplink to the UE in the cell (such as figure 1 UE2) in the downlink received interference

Embodiment Construction

[0057] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0058] In order to facilitate the understanding of the technical solution of the embodiment of the present invention, firstly, the resource configuration solution for large-scale interference intensity measurement used in the prior art is introduced. The existing large-scale interference strength measurement resource configuration scheme is the transmitting node (first user equipment (User Equipment, UE) / first evolved base station (Evolved Node B, eNB) / transmission receiving node (Transmission Reception) Point, TRP)) to configure a "clean" resource, so that the interference measurement signal from the transmitting node measured on the resource will accurately reflect the interference intensity level generated by the transmitting node. Specifically, such as figure 2 and image 3 As shown, among them, ...

Abstract

The embodiment of the present invention discloses a signal transmission method and related equipment, including: the transmitting node generates the first signal; the transmitting node transmits the first signal on the first resource, the transmission power of the first signal is non-zero, and the transmitting node sends The third signal of is superimposed with the first signal, and the third signal is used by the receiving node to obtain the first interference power; wherein, the transmitting node does not send a signal on the second resource, and there is a fourth signal on the second resource, and the fourth signal is used for The receiving node obtains the second interference power, and the first interference power and the second interference power are used to obtain the interference power of the transmitting node to the receiving node. The embodiment of the present invention is beneficial to accurately determine the interference power of the transmitting node to the receiving node without affecting resource occupation of other node devices to the first resource and the second resource.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a signal transmission method and related equipment. Background technique [0002] With the development of wireless network technology, various new services emerge one after another, and different services have different requirements for resources. This requires that limited resources can be used more efficiently in future wireless networks. In order to achieve this goal, the dynamic time division duplex D-TDD technology has attracted more and more attention. D-TDD means that the network can flexibly adjust the configuration of uplink and downlink subframes, that is, the network can dynamically adjust the configuration of TDD uplink and downlink subframes according to the requirements of different services for uplink and downlink resources, so as to achieve the purpose of optimizing resource utilization. [0003] But in the wireless network system using D-T...
