Embodiment approach

[0359] 1. The network side configures the first threshold and / or the second threshold, and the base station or UE independently selects the corresponding transmission mode according to the above principles based on the measurement result of cross-link interference and the comparison result with the threshold.

[0360] 2. The base station directly uses or configures the above transmission mode for the UE according to the cross-link interference measurement result (the cross-link interference measurement result may be measured by the base station itself, or may be reported by the UE after measurement).

[0361] Eighth example:

[0362] It involves the interference scenario between gNB and gNB, especially the interference problem in the scenario where the transmitting end adopts directional beam (directional beam) and the receiving end adopts omnidirectional reception.

[0363] Such as Figure 7 As shown, the transmitting end (gNB1 and UE2-1 / UE2-2 / UE2-3 under gNB2) adopts direct...

Abstract

The embodiment of the invention discloses an interference measurement method and apparatus, and a timing deviation measurement method. The method comprises the following steps: a first communication device obtains first transmission configuration information, wherein if a second communication device is a first base station, the first communication device is a second base station or user equipmentUE connected to a cell formed by the second base station, and if the second communication device is first UE, the first communication device is second UE or a neighboring base station of the base station to which the first UE is connected; and performing measurement on a first reference signal according to the first transmission configuration information to form a first measurement result, whereinthe first measurement result is used for cross-link interference coordination.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an interference measurement method and device and a timing deviation measurement method. Background technique [0002] The Long Term Evolution (LTE) system supports frequency division duplex (Frequency Division Duplex, FDD) operation on paired spectrum (downlink works on one carrier, and uplink works on another carrier). It also supports Time Division Duplex (TDD) operation on an unpaired carrier. The existing TDD operation mode can only apply a limited number of uplink and downlink subframe allocation configurations (corresponding to configuration 0 to configuration 6), and the adjacent cells adopt the same configuration, that is, have the same sending direction. Enhanced interference mitigation and traffic adaptation (eIMTA) can semi-statically (more than 10ms) configure the uplink and downlink directions of the LTE system, and different TDD uplink and downlink sub-units ...
