Problems solved by technology

However, if TRP 2 221 transmits through Tx beam #9 in its own cell, said UE 212 in cell 1 210 may experience strong interference 223, resulting in low SINR transmission
If the UE 212 selects another beam pair for transmission, the interference from the interfering TRP can be avoided, but the problem at this time is that the UE 212 does not know which Tx beam the interfering TRP 221 will use

Abstract

The present disclosure relates to a processing device (2200) for interference-aware beam pair selection (2201), in particular a processing device (2200) in a transmit-receive point. The processing device (2200) is used to select (2201) a beam pair (2204) from a set of candidate beam pairs (i, j) (2202), so as to establish a service sending device and a communication link between receiving devices, wherein each of said candidate beam pairs (2202) includes a transmitting beam j of said serving transmitting device and a receiving beam i of said receiving device, said selection (2201) being based on at least Statistical data (2203) of usage of at least one interfering transmission beam (m, k) of one interfering transmitting device m.

Description

technical field [0001] The present disclosure relates to beam pair selection techniques for interference awareness, especially beam pair selection based on statistical data. In particular, the present disclosure relates to a processing device and method for interference-aware beam pair selection. The selection is based on statistical data of usage of at least one interfering transmission beam by at least one interfering transmitting device. The present disclosure also relates to a transmission and reception point, such as a base station or user equipment, which includes the processing device. Background technique [0002] Wireless communication is often affected by low signal-to-noise ratio (SNR) and adverse propagation effects, especially high-frequency communication, such as millimeter (mm) wave communication. One technique used to improve communications, especially mmWave communications, is directional transmission. For example, if figure 1 As shown in the example in ...
