Abstract:
1. A method of transmitting, via a radio communications uplink, a plurality of indications of desired radio communications downlink characteristics from a user equipment to a node of a cellular wireless network, said indications each relating to one or more components of a radio communications link from the node to the user equipment, the method comprising transmitting said plurality of indications of desired radio communications downlink characteristics successively at different cycles by: determining a first parameter, indicating a more preferred number of components which is a number of components which the user equipment would prefer to be included in said radio communications link by the user equipment; determining a second parameter, indicating a less preferred number of components which is a number of components which may be included in said radio communications link should the more preferred number of components not be included; calculating first additional parameters relating to the desired radio communications link quality corresponding to the first parameter; calculating second additional parameters relating to the desired radio communications link quality on the basis of the second parameter; transmitting said first additional parameters in a first signalling field via said radio communications uplink; and transmitting said second additional parameters in a second signalling field via said radio communications uplink, wherein the first parameter, upon which the calculation of the first additional parameters included in the first signalling field is based, is a parameter which is variable between different cycles, wherein the second parameter, upon which the calculation of the second additional parameters included in the second signalling field is based, is a parameter which is variable between different cycles, and wherein said determining of the second parameter is performed by processing a third parameter.
