Facilitating open loop power control in TD-SCDMA multi-carrier systems

摘要

Open loop power control in Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) multi-carrier systems is facilitated through the determination of a value for open loop control on a primary carrier frequency which is then used to perform open loop control on at least one secondary carrier frequency in the multi-carrier system. This determined open loop control value may be applied using the value determined on the primary carrier frequency, or may be further adjusted using an estimated difference between received power of the primary carrier frequency and the secondary carrier frequencies, in selected aspects. When the pilot signals in the secondary carrier frequencies are transmitted at different power levels, this open loop control value may be further adjusted with a transmit power level offset.

1. A method for open loop power control in a multi-carrier Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) communication system, said method comprising:
determining a value for open loop power control on a primary carrier frequency in said multi-carrier TD-SCDMA communication system; and performing open loop power control on at least one secondary carrier frequency in said multi-carrier TD-SCDMA system based on said determined value, a user equipment (UE) of the multi-carrier TD-SCDMA communication system configured to receive a first communication from the primary carrier frequency while receiving a second communication from the primary carrier frequency and/or the at least one secondary carrier frequency.
