1. A method of communicating code allocations in a cellular radio system, the method comprising:
- allocating to a first mobile terminal a first code in a timeslot;
allocating to a second mobile terminal a second code in the timeslot;
generating a message including an indication of the second code allocated to the second mobile terminal; and
signaling to the first mobile terminal the message.

Abstract
The present invention relates to demodulation of radio signals from a base station having collocated transmit antennas, and more particularly to signaling allocation information from a base station to a mobile terminal. The allocation information may include timeslot and code information of allocation to other mobile terminals. Some embodiments of the present invention facilitate a mobile terminal'"'"'s ability to receive and demodulate a signal containing multiple interfering signals by communicating codes allocated to other mobile terminals.

7. A method of communicating code allocations by a base station in a cellular radio system, the method comprising:
-
determining a first set of one or more codes in a timeslot to allocate to a first mobile terminal;
determining a second set of one or more codes in the timeslot to allocate to a second mobile terminal;
generating an allocation table that indicates the first and second sets of codes are allocated; and
transmitting the allocation table. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of compiling an allocation table in a first mobile terminal, the method comprising:
-
monitoring one or more first channels;
receiving a signal in a timeslot, wherein the signal includes a data payload and a training sequence; and
extracting allocation information from the data payload. - View Dependent Claims (22, 23, 24, 25)

26. A method of compiling an allocation table in a first mobile terminal, the method comprising:
-
monitoring one or more first channels for allocation messages;
receiving on the first channels a first allocation message;
receiving on the first channels a second allocation message;
determining the first allocation message is directed to the first mobile terminal;
determining the second allocation message is directed to a different mobile terminal; and
building the allocation table from information received in the second allocation message, wherein the information includes a code allocated to the different mobile terminal.
