A method of requesting a plurality of different characteristic indicators from a second communication apparatus (MS) in a wireless communication network comprising a first communication apparatus (BS) and a plurality of such second communication apparatuses (MS) which communicate with the first communication apparatus using a shared communication frame, the method comprising; the first communication apparatus (BS) transmitting () a single standing instruction to the second communication apparatus (MS) to interchange between sending the different characteristic indicators in a feedback window allocated to the second communication apparatus in the shared communication frame.

Method and system for communicating in a wireless communication systems

A method of requesting a plurality of different characteristic indicators from a second communications apparatus in a wireless communications network including a first communications apparatus and a plurality of such second communications apparatuses which communicate with the first communications apparatus, the method includes the first communications apparatus transmitting a single standing instruction to the second communications apparatus defining at least two interleaving patterns, each interleaving pattern specifying one or more of the characteristic indicators and defining a pattern according to which the second communications apparatus is to interleave the specified characteristic indicators in a single feedback channel allocated to the second communications apparatus, the single standing instruction further defining a selection signal to be transmitted from the first communications apparatus to the second communications apparatus according to which the second communications apparatus is to select one of the interleaving patterns.

Wireless communication system and network comprising a first communications apparatus and a second communications apparatus which communicates with the first communications apparatus

The invention relates to a method in a cluster of cells in a communications network comprising switching between a first state, in which a first number of radio stations is active and a second state in which a second, different number of radio stations is active, wherein the second state is intended to provide the same geographic coverage as the first state but a different capacity, and in which the transition between states is carried out using transmission parameter adjustment, which take place in a plurality of radio stations and are co-ordinated in time for these radio stations.

Transition mechanism for energy efficient mobile overlay network

A method in a wireless communication system that includes a user equipment, an anchor network station and at least one assisting network station, where the user equipment transmits the same data to the network stations and the network stations each transmit an acknowledgement of the data to the user equipment in response. The at least one assisting network station also forwards the data to the anchor network station.
