ABSTRACT:
Techniques to time-share a common channelization code among multiple terminals for compressed mode transmissions. Each terminal is initially assigned a respective channelization code used to channelize data transmitted in non-compressed frames for the terminal. A common channelization code used to channelize data transmitted in compressed frames for the terminals is also selected. Each compressed frame includes one or more compressed transmissions and all or a portion of a transmission gap. The compressed frames for the terminals are scheduled such that the compressed transmissions for the compressed frames do not overlap. Thereafter, non-compressed frames for each terminal are channelized with the channelization code assigned to the terminal, and compressed frames for the terminals are channelized with the common channelization code. The compressed frames may be scheduled to be (1) non-overlapping at their frame boundaries, (2) non-overlaping with respect to the compressed transmissions, and/or (3) interlaced.
