Abstract
In a method of signalling active assignments to an ordered group of wireless terminals in communication with a base station in a wireless communication system, each wireless terminal of the ordered group having a corresponding position within the ordered group, the base station: determines an allocation of active assignments for the ordered group, the allocation corresponding to a number of active assignments; determines an index value identifying the allocation in a set of possible allocations for the number of active assignments for the ordered group; and transmits the index value to at least one wireless terminal of the ordered group of wireless terminals
Claims25
A method of signalling active assignments to an ordered group of wireless terminals in communication with a base station in a wireless communication system, each wireless terminal of said ordered group having a corresponding position within said ordered group, said method comprising:
- at said base station:
- determining an allocation of active assignments for said ordered group, said allocation corresponding to a number of active assignments;
- determining an index value identifying said allocation in a set of possible allocations for said number of active assignments for said ordered group;
- and
- transmitting said index value to at least one wireless terminal of said ordered group of wireless terminals.
A base station forming part of a communication system, said base station in communication with an ordered group of wireless terminals, each wireless terminal of said ordered group having a corresponding position within said ordered group, said base station comprising logic operable to:
- determine an allocation of active assignments for said ordered group, said allocation corresponding to a number of active assignments;
- determine an index value identifying said allocation in a set of possible allocations for said number of active assignments for said ordered group;
- and
- transmit said index value to at least one wireless terminal of said ordered group of wireless terminals.
A wireless terminal comprising logic operable to:
- receive from a base station an indication that said wireless terminal has been added to an ordered group of wireless terminals;
- receive from said base station a terminal assignment index (TAI);
- and
- use said TAI to derive an ordered assignment bitmap (OAB), where each wireless terminal in said ordered group is associated with a respective bit position of said OAB.
