WIRELESS COMMINICATION SYSTEM AND METHOD FOR ASSIGNING A CHANNEL IN SAID WIRELESS COMMUNICATION SYSTEM
First Claim
1. A Wireless communication distributed antenna system, comprising:
- an antenna unit comprising a plurality of antenna elements;
a selector arranged to select at least one of the antenna elements as serving antenna for communication with user equipment; and
a code allocator arranged to allocate a code for channel estimation support for said communication between the serving antenna and the user equipment and a control unit arranged to control said communication based on the selected serving antenna and the allocated code, whereincode allocator is arranged to assign the code to said user equipment and the control unit is arranged to control the serving antenna so as to transmit the code assigned to the user equipment, wherein the code allocator is further arranged to determine interference between communication channels to different pieces of equipment and to assign the same code to a plurality of pieces of equipment in consideration of said determined interference.

Abstract
The present invention relates to a wireless communication system. The wireless communication system comprises an antenna unit comprising a plurality of antenna elements, selecting means arranged to select at least one of the antenna elements as serving antenna for communication with user equipment, means for code allocation arranged to allocate a code for channel estimation support for the communication between the serving antenna and the user equipment, and a control unit arranged to control the communication based on the selected serving antenna and the allocated code. The means for code allocation are arranged to assign the code to said user equipment. The control unit is arranged to control the serving antenna so as to transmit the code assigned to the user equipment.

12. A method for assigning a channel for communication with user equipment in a wireless communication distributed antenna system, comprising the steps of:
-
receiving a request for a call from a user equipment, assigning a code for channel estimation support to a channel, selecting a serving set of antennas from a plurality of antenna elements for communication with said user equipment over said channel, and controlling communication with said user equipment over said selected serving set of antennas, said communication comprising said code for channel estimation support, wherein the step of assigning a code for channel estimation support comprises assigning a code to the user equipment, and the step of assigning a code comprises determining interferences between communication channels related to different pieces of user equipment and to assign the same code as already used by another piece of equipment based on the determined interference with said another piece of equipment. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
