Abstract
A method of operating a communications device comprises receiving from an infrastructure equipment of a radio network part of the wireless communications mobility information indicating one or both of whether the infrastructure is non-stationary and a location of the infrastructure equipment, and adapting an operation of the communications device in accordance with the mobility information. The adapted operation includes configuring the communications devices for transmitting signals to the infrastructure equipment or receiving signals from the infrastructure equipment according to the mobility information.
Claims18
A method of operating by a wireless communications device for transmitting or receiving via a wireless communications network, the method comprising:
- receiving, from a non-stationary wireless base station of a radio network part of the wireless communications network, mobility information indicating a current location of the non-stationary wireless base station;
- determining, by the wireless communications device, a location of the wireless communications device;
- determining a relative bearing of the non-stationary wireless base station with respect to the wireless communications device based on the current location of the non-stationary wireless base station as determined from the mobility information received from the non-stationary wireless base station and the location of the wireless communications device as determined by the wireless communications device;
- and
- adapting an operation of the wireless communications device in accordance with the relative bearing, wherein the adapting comprises one or both of:
- adapting a transmit beam selection by adapting a direction of transmitting a beam of signals according to the determined relative bearing, or
- adapting a receive beam selection by adapting a direction of receiving signals as a beam according to the determined relative bearing.
A method of operating a wireless base station forming part of a wireless communications network, the method comprising:
- determining a location of the wireless base station;
- determining a location of one or more wireless communications devices;
- selecting a recommended uplink beam index based on the location of the wireless base station as determined by the wireless base station and the location of the one or more wireless communications devices;
- generating mobility information that includes the recommended uplink beam index and that indicates one or both of whether the wireless base station is non-stationary and the location of the wireless base station for use by the one or more wireless communications devices to adapt an operation of the one or more wireless communications devices in accordance with the mobility information for transmitting signals to the wireless base station or receiving signals from the wireless base station according to the mobility information;
- and
- transmitting, by the wireless base station to the one or more wireless communications devices, the mobility information including the recommended uplink beam index determined based upon the location of the base station as determined by the wireless base station.
A wireless communications device comprising:
- transmitter circuitry configured to transmit signals via a wireless access interface of a wireless communications network,
- receiver circuitry configured to receive signals transmitted via the wireless communications network, and
- controller circuitry configured to
- control the transmitter circuitry and the receiver circuitry;
- receive, from a non-stationary wireless base station of a radio network part of the wireless communications network, mobility information indicating a current location of the non-stationary wireless base station;
- determine, by the wireless communications device, a location of the wireless communications device;
- determine a relative bearing of the non-stationary wireless base station with respect to the wireless communications device based on the current location of the non-stationary wireless base station as determined from the mobility information received from the non-stationary wireless base station and the location of the wireless communications device as determined by the wireless communications device;
- and
- adapt the control of one or both of the transmitter circuitry and the receiver circuitry according to the determined relative bearing by
- adapting a transmit beam selection to be in a direction of transmitting a transmit beam of signals according to the determined relative bearing, or
- adapting a receive beam selection to be in a direction of receiving signals as a receive beam according to the determined relative bearing.
