Abstract
Method and apparatus for determining a transmission configuration for a dedicated channel in a wireless communication system. In one embodiment, an optimum configuration is determined based on minimizing Peak-to-Average Ratio (PAR) of the channel. The configuration is defined as a transmission pair of transmission branch and spreading code. The transmission branch may be the In-Phase (I) branch or the Quadrature (Q) branch. PAR analysis may be performed off-line to determine the optimum configuration. In operation, if the spreading code of the optimum configuration is used by another channel, the next best optimum code is used.
Claims4
A non-transitory computer-readable storage medium having stored thereon computer executable instructions for channelization of a plurality of communication channels in a spread spectrum communication system, wherein said plurality of channels includes dedicated physical data channels and a high speed dedicated physical control channel and wherein said channelization is by spreading said plurality of communication channels by a set of finite number of spreading codes, the stored computer-executable instructions configured to cause a computer to perform steps comprising:
- spreading said high speed dedicated physical control channel using one spreading code of said set of finite number of spreading codes and on either a Quadrature branch (Q-branch) or In-phase branch (I-branch) of a channel spreader;
- selecting either said Q-branch or I-branch of said channel spreader for the spreading of said high speed dedicated physical control channel based on a number of said dedicated physical channels in said plurality of communication channels;
- selecting said one spreading code from said set of finite number of spreading codes based on whether said high speed dedicated physical control channel is being spread on said Q-branch or said I-branch of said channel spreader and said number of said dedicated physical channels in said plurality of communication channels.
