Abstract
In a digital cellular radio communication network, modulation and channel coding for a plurality of radio links of a given cell is determined in response to quality information received during network operation and indicative of communication quality associated with the plurality of radio links. A single modulation and channel coding scheme is determined in response to the quality information, and the single modulation and channel coding scheme is used in each of the links.
Claims24
A method of administering modulation and channel coding in a plurality of radio links of a given cell in a digital cellular radio communication network, comprising:
- during operation of the network, receiving individual quality measurements respectively indicative of the quality of at least some of said plurality of radio links, and combining said individual quality measurements together and producing therefrom composite quality information;
- determining a single modulation and channel coding scheme to be used in all of said radio links in response to the composite quality information;
- and
- in all of the radio links, performing radio transmissions using the single modulation and channel coding scheme.
An apparatus for controlling modulation and channel coding in a plurality of radio links of a given cell in a digital cellular radio communication network, comprising:
- an input for receiving, during operation of the network, information indicative of communication quality associated with the plurality of radio links;
- a selector coupled to said input for determining, in response to the quality information, a single modulation and channel coding scheme to be used in all of said radio links;
- and
- an output coupled to said selector for outputting information indicative of the single modulation and channel coding scheme to be used in all of said radio links.
An apparatus for controlling modulation and channel coding in a plurality of radio links of a given cell in a digital cellular radio communication network, comprising:
- an input for receiving, during operation of the network, information indicative of communication quality associated with the plurality of radio links;
- a selector coupled to said input for determining, in response to the quality information, a single modulation and channel coding scheme to be used in all of said radio links;
- a filter coupled between said input and said selector for receiving from said input individual quality measurements which are respectively indicative of the quality of at least some of said plurality of radio links, and further for combining said individual quality measurements together to produce composite quality information, said selector responsive to said composite quality information for determining the single modulation and channel coding scheme;
- and
- an output coupled to said selector for outputting information indicative of the single modulation and channel coding scheme to be used in all of said radio links.
