Abstract

A wireless transmit/receive unit (WTRU) may receive a request to perform directional signal measurements for received signals. The WTRU may transmit, based on the request and position information associated with the WTRU, directional signal measurements to facilitate generation of a directional radio environment map (DREM). The WTRU may receive a request to switch beams based on the DREM.

Claims (30)

1 . A wireless transmit/receive unit (WTRU) comprising:

a receiver configured to receive, from a base station (BS), a first request to perform directional signal measurements for a plurality of received signals;

the receiver further configured to receive, from the BS, a second request to provide position information associated with the WTRU;

a transmitter configured to transmit, based on the first request and the position information associated with the WTRU, directional signal measurements to facilitate generation of a directional radio environment map (DREM); and

the receiver further configured to receive a third request to switch beams based on the DREM.

2 . The WTRU of claim 1 further comprising:

the receiver further configured to receive a request from the BS to provide orientation data associated with the WTRU; and

the transmitter further configured to transmit the orientation data.

3 . The WTRU of claim 1 further comprising:

the transmitter further configured to transmit historical data on beams used by the WTRU.

4 . The WTRU of claim 1 , wherein the directional signal measurements are performed on inter-cell signals.

5 . The WTRU of claim 1 further comprising:

the receiver further configured to receive position data associated with the BS.

6 . The WTRU of claim 1 further comprising:

a processor configured to filter the directional signal measurements based on time and GPS coordinates.

7 . A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

receiving, from a base station (BS), a first request to perform directional signal measurements for a plurality of received signals;

receiving, from the BS, a second request to provide position information associated with the WTRU;

transmitting, based on the first request and the position information associated with the WTRU, directional signal measurements to facilitate generation of a directional radio environment map (DREM); and

receiving a third request to switch beams based on the DREM.

8 . The method of claim 7 further comprising:

receiving, from the BS, a request to provide orientation data associated with the WTRU; and

transmitting, by the WTRU, the orientation data.

9 . The method of claim 7 further comprising:

transmitting historical data on beams used by the WTRU.

10 . The method of claim 7 , wherein the directional signal measurements are performed on inter-cell signals.

11 . The method of claim 7 further comprising:

receiving, by the WTRU, position data associated with the BS.

12 . The method of claim 7 further comprising:

filtering, by the WTRU, the directional signal measurements based on time and GPS coordinates.
