Abstract
A method and system is disclosed wherein timeslots designated in a wireless communication system as Common Physical Channel (CPCH) timeslots may be reused for user traffic. A CPCH timeslot used in a first cell may be reused by a second cell, assuming the first and second cells transmit control information in different CPCH timeslots, for user traffic. The second cell is permitted to reuse the timeslot in which the first cell is transmitting control information so long as the second cell's reuse of that timeslot does not degrade reception of control information in the first cell.
Claims12
A base station, including a processor, the processor configured to receive a quality metric reported from at least one wireless transmit/receive unit (WTRU) on a time slot designated for control information, transmit control information in a time slot designated specifically for the base station, wherein a neighboring base station uses a different time slot for transmission of control information relating to the neighboring base station, and adjust a maximum power limit for transmission within the cell associated with the base station;
- and
- whereby the base station may transmit traffic data to the WTRU on the time slot designated for control information within the assigned maximum limit.
A wireless transmit/receive unit (WTRU), the WTRU including a processor, the processor configured to transmit a quality metric on a time slot designated for control information, receive a maximum power limit adjustment signal, and adjust its transmission power in accordance with the received maximum power limit adjustment signal;
- and
- whereby the WTRU may receive traffic data from a base station on the time slot designated for control information within the assigned maximum limit.
