Abstract
A method of operating a wireless communication system is disclosed (FIG. 6). The method includes receiving a virtual cell identification (VCID) parameter (600) from a remote transmitter. A base sequence index (BSI) and a cyclic shift hopping (CSH) parameter (604,606) are determined in response to the VCID. A pseudo-random sequence is selected in response to the BSI and CSH (610,612). A reference signal is generated using the selected pseudo-random sequence (614).
Claims20
A method of operating a wireless communication system, comprising:
- receiving a signal from a base station;
- selecting a cell-specific parameter in response to a first state of the signal;
- selecting a user-specific parameter in response to a second state of the signal;
- and
- transmitting an uplink reference signal in response to the selected parameter.
A method of operating a wireless communicating system comprising:
- transmitting uplink control information from a second base station to a first base station;
- and
- determining uplink control resources for a user equipment (UE) in a cell served by the first base station in response to the uplink control information.
A method of operating a wireless communication system, comprising the steps of:
- transmitting at least two uplink transmit power control commands from a network to a user equipment;
- receiving a first uplink transmit power control command for transmitting uplink control information and/or a sounding reference signal to a first base station;
- receiving a second uplink transmit power control command for transmitting a sounding reference signal to a second base station;
