Abstract

The disclosure relates to a radio transceiving device, comprising: a multi-antenna array; a main transceiver coupled to the multi-antenna array, wherein the main transceiver is configured to beamform a first plurality of digital signals over a total transceiver bandwidth, wherein a part of the beamforming is processed in digital domain and another part of the beamforming is processed in analog domain; and an auxiliary transceiver coupled to the multi-antenna array, wherein the auxiliary transceiver is configured to beamform a second plurality of digital signals over a fraction of the total transceiver bandwidth, wherein the beamforming is processed in digital domain.

Dependent claims

A radio transceiving device, comprising:

a multi-antenna array;
a main transceiver coupled to the multi-antenna array, wherein the main transceiver is configured to beamform a first plurality of digital signals over a total transceiver bandwidth, wherein a part of the beamforming is processed in a digital domain and another part of the beamforming the first plurality of digital signals is processed in an analog domain;
and
an auxiliary transceiver coupled to the multi-antenna array, wherein the auxiliary transceiver is configured to beamform a second plurality of digital signals over a fraction of the total transceiver bandwidth, wherein the beamforming the second plurality of digital signals is processed in the digital domain;
wherein the auxiliary transceiver is configured to provide initial access for a user equipment to an access point;
and
wherein the main transceiver is configured to perform user data transmission between the user equipment and the access point.

4 more elements

A method for providing initial access between a user equipment (UE) and an access point (AP), the method comprising:

transmitting a plurality of broadcast signals in different beam directions by the AP using a fraction of a total transceiver bandwidth of the AP, wherein the plurality of broadcast signals comprise information about a beam sector identifier and a cell identifier of the AP;
receiving at least part of the broadcast signals by the UE using a fraction of a total transceiver bandwidth of the UE;
determining a preferential beam direction by the UE based on at least part of the broadcast signals received from the AP;
using an auxiliary transceiver of a first radio transceiver device for transmitting the plurality of broadcast signals by the AP;
and
using an auxiliary transceiver of a second radio transceiver device for receiving the at least part of the broadcast signals by the UE.
