Abstract
An apparatus, method and computer program is described comprising: receiving downlink positioning signals from each of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein each downlink positioning signal is received from a downlink beam direction for the respective communication node; determining an angle of arrival and/or a time of arrival for each of the received downlink positioning signals; and determining an uplink positioning signal beam configuration based, at least in part, on the determined angle of arrival and/or the determined time of arrival for said received downlink positioning signals.
Claims19
An apparatus comprising at least one processor;
- and
- memory including computer program code, the memory and the computer program code configured, with the at least one processor, to cause the apparatus, when the program code is executed by the at least one processor, to perform:
- receiving downlink positioning signals from respective ones of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein respective ones of the downlink positioning signals are received from a downlink beam direction for the respective communication node;
- determining at least one of the following:
- an angle of arrival or a time of arrival for respective ones of the received downlink positioning signals;
- and
- determining an uplink positioning signal beam configuration based, at least in part, on at least one of the following:
- the determined angle of arrival or the determined time of arrival, wherein a number of uplink beams or resources available for use in the uplink positioning signal beam configuration is less than a number of communication nodes from which downlink positioning signal beams are received.
A method comprising:
- receiving downlink positioning signals from respective ones of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein respective ones of the downlink positioning signals are received from a downlink beam direction for the respective communication node;
- determining at least one of the following:
- an angle of arrival or a time of arrival for respective ones of the received downlink positioning signals;
- and
- determining an uplink positioning signal beam configuration based, at least in part, on at least one of the following:
- the determined angle of arrival or the determined time of arrival, wherein a number of uplink beams or resources available for use in the uplink positioning signal beam configuration is less than a number of communication nodes from which downlink positioning signal beams are received.
A computer program product comprising a tangible computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions for causing an apparatus to perform at least the following:
- receiving downlink positioning signals from respective ones of a plurality of communication nodes of a mobile communication system at a user device of the mobile communication system, wherein respective ones of the downlink positioning signals are received from a downlink beam direction for the respective communication node;
- determining at least one of the following:
- an angle of arrival or a time of arrival for respective ones of the received downlink positioning signals;
- and
- determining an uplink positioning signal beam configuration based, at least in part, on at least one of the following:
- the determined angle of arrival or the determined time of arrival, wherein a number of uplink beams or resources available for use in the uplink positioning signal beam configuration is less than a number of communication nodes from which downlink positioning signal beams are received.
