Reporting in different dimensions
The disclosure pertains to a method for operating a terminal ( 10 ) in a wireless communication network, the method comprising performing reporting based on a configuration, the configuration indicating the timing of reporting of first angular transmission information and/or indicating the timing of reporting of second angular transmission information. The disclosure also pertains to related methods and devices.
1. A method for operating a terminal in a wireless communication network, the method comprising:
performing reporting based on a configuration, the configuration indicating a timing of reporting of first angular transmission information and/or indicating a timing of reporting of second angular transmission information;
wherein the timing of reporting of the first and second angular transmission information is such that reporting pertaining to a quicker varying angular transmission information of the first and second angular transmission information is performed more often and/or quicker than the reporting pertaining to the other angular transmission information of the first and second angular transmission information; and
wherein the quicker varying angular transmission information of the first and second angular transmission information comprises a beam group indicator and a Precoder Matrix Indicator (PMI).
2. A terminal for a wireless communication network, the terminal comprising:
communication circuitry; and
processing circuitry configured to:
perform reporting based on a configuration, the configuration indicating a timing of reporting, via the communication circuitry, of first angular transmission information and/or indicating a timing of reporting of second angular transmission information;
wherein the timing of reporting of the first and second angular transmission information is such that reporting pertaining to a quicker varying angular transmission information of the first and second angular transmission information is performed more often and/or quicker than the reporting pertaining to the other angular transmission information of the first and second angular transmission information; and
wherein the quicker varying angular transmission information of the first and second angular transmission information comprises a beam group indicator and a Precoder Matrix Indicator (PMI).
3. A method for operating a network node in a wireless communication network, the method comprising:
configuring a terminal for performing reporting, wherein configuring comprises indicating different timings for reporting of first angular transmission information and second angular transmission information;
wherein a shorter timing is assigned to the angular transmission information of the first and second angular transmission information varying faster; and
wherein the fast varying angular transmission information of the first and second angular transmission information comprises a beam group indicator and a Precoder Matrix Indicator (PMI).
4. A network node for a wireless communication network, the network node comprising:
communication circuitry; and
processing circuitry configured to:
configure a terminal for performing reporting, wherein configuring comprises indicating, via the communication circuitry, different timings for reporting of first angular transmission information and second angular transmission information;
wherein a shorter timing is assigned to the angular transmission information of the first and second angular transmission information varying faster; and
wherein the fast varying angular transmission information of the first and second angular transmission information comprises a beam group indicator and a Precoder Matrix Indicator (PMI).
