Problems solved by technology

[0003] This situation is problematic because the candidate beam pair detected at the transmitter with a single polarization mode that provides the greatest channel gain does not necessarily provide the greatest capacity for transmission with two orthogonal polarization modes, Also not optimal for choosing beam pairs for single-polarization transmission

Abstract

A method performed by a transmitter node is disclosed for enabling receive beam selection at one or more receiver nodes. The method includes obtaining a polarization profile, where the polarization profile defines respective polarizations for a sequence of probe opportunities. The method includes transmitting pilot signals in a single transmit beam in each of a sequence of probe occasions according to a polarization profile. The polarization profile defines a first polarization used in N probing occasions in a sequence of probing occasions and a second polarization used in M probing occasions, where M is less than N and M is not zero.

Description

[0001] The present disclosure relates to the field of wireless communications. The present disclosure relates to a method of implementing receive beam selection at one or more receiver nodes, a method of selecting a receive beam for use in communicating with a transmitter node, associated transmitter nodes, and associated receiver nodes. Background technique [0002] Wireless communication systems operating at millimeter-wave frequencies (such as tens of GHz) usually require beamforming transmissions to overcome large path losses. Therefore, it is necessary to select beam pairs that provide an appropriate link (also called a channel) between the transmitter and receiver, such as a spatial filter on the transmitter side (which can be called a transmit beam or a transmission beam) and a receiver-side The spatial filter (may be referred to as receive beam or reception beam). During the initial beam selection and subsequent beam adjustment process, several candidate beam pairs ma...
