Remote beam steering for a millimeter wave repeater
A wireless communication device can include modem circuitry to connect the UE to a repeater over a side-link connection. The device can also include processing circuitry to control a repeater beamforming process to select a beam angle from the repeater to a base station and initiate a communication procedure using the selected beam angle. Other methods, systems and apparatuses are described.
1 . An apparatus of a user equipment (UE), the apparatus comprising:
modem circuitry configured to connect the UE to a repeater over a side-link connection; and
processing circuitry coupled to the modem circuitry and configured to:
control a repeater beamforming process to select a beam angle from the repeater to a base station; and
initiate a communication procedure using the selected beam angle;
disable non-side-link beamforming and beam tracking upon connecting the repeater over the side-link connection; and
re-enable non-side-link beamforming and beam tracking upon disconnecting the side-link connection.
2 . The apparatus of claim 1 , wherein the communication procedure includes a random access procedure.
3 . The apparatus of claim 1 , further comprising memory, wherein the modem circuitry is configured to connect to an additional repeater over the side-link connection, and wherein the processing circuitry is configured to control the additional repeater to find an additional beam angle from the additional repeater to the base station and to store configuration information for the additional repeater in the memory.
4 . The apparatus of claim 3 , wherein the processing circuitry is further configured to:
detect an interference condition in communications with the repeater; and
initiate access to the additional repeater responsive to the detecting and using the stored configuration information for the additional repeater.
5 . The apparatus of claim 1 , wherein the controlling comprises controlling the repeater to communicate, successively, over a plurality of beam angles until a beam angle is selected for communicating to the base station based on signal quality.
6 . A non-transitory computer-readable medium including instructions that, when executed on a processor, cause the processor to perform operations including:
connecting a user device to a repeater over a side-link connection;
controlling a repeater beamforming process, by the user device, to select a beam angle from the repeater to a base station;
initiating, by the user device, a communication procedure using the selected beam angle;
disabling non-side-link beamforming and beam tracking upon connecting the repeater over the side-link connection; and
re-enable non-side-link beamforming and beam tracking upon disconnecting the side-link connection.
7 . The non-transitory computer-readable medium of claim 6 , wherein the operations further comprise:
connecting to an additional repeater over the side-link connection;
controlling the additional repeater to find a second beam angle from the additional repeater to the base station; and
storing configuration information for the additional repeater.
8 . The non-transitory computer-readable medium of claim 7 , wherein the operations further comprise:
detecting an interference condition in communications with the repeater; and
initiating access to the additional repeater responsive to the detecting and using the stored configuration information for the additional repeater.
9 . The non-transitory computer-readable medium of claim 6 , wherein the user device communicates to the repeater using an omnidirectional, non-beamforming antenna pattern.
10 . The non-transitory computer-readable medium of claim 6 , wherein the controlling comprises controlling the repeater to communicate, successively, over a plurality of beam angles until a beam angle is selected for communicating to the base station.
11 . The non-transitory computer-readable medium of claim 6 , wherein the controlling comprises monitoring a synchronization symbol block (SSB) to detect the beam angle.
12 . The non-transitory computer-readable medium of claim 6 , wherein the base station comprises a 5 th generation NodeB (gNB).
13 . The non-transitory computer-readable medium of claim 6 , wherein the side-link connection comprises a Bluetooth connection.
14 . The non-transitory computer-readable medium of claim 6 , wherein the side-link connection comprises a wireless local area network (WLAN) connection.
15 . The non-transitory computer-readable medium of claim 6 , wherein the side-link connection comprises a wired connection.
16 . A method for configuring repeater beamforming, the method comprising:
connecting a user device to a repeater over a side-link connection;
controlling a repeater beamforming process to select a beam angle from the repeater to a base station;
initiating a communication procedure using the selected angle;
disabling non-side-link beamforming and beam tracking upon connecting the user device to the repeater over the side-link connection; and
re-enabling non-side-link beamforming and beam tracking upon disconnecting the side-link connection.
17 . The method of claim 16 , further comprising:
connecting to an additional repeater over the side-link connection;
controlling the additional repeater to find a second beam angle from the additional repeater to the base station; and
storing configuration information for the additional repeater.
18 . The method of claim 17 , further comprising:
detecting an interference condition in communications with the repeater; and
initiating access to the additional repeater responsive to the detecting and using the stored configuration information for the additional repeater.
