Abstract:
1. A method of interference avoidance in an IFDMA communication system, the method comprising the steps of: for a particular sector, utilizing for transmissions a portion of an IFDMA channelization code tree as a code resource block, the code resource block capable of supporting transmission to/from a plurality of remote units; for the particular sector, scheduling transmissions to/from remote units using IFDMA channelization codes from the sector's code resource block up to a point where the code resource block cannot support a particular transmission, beyond that point, the particular transmission is scheduled to be transmitted using an IFDMA channelization code from a code resource block assigned to another sector; and wherein the sub-tree of the IFDMA channelization code tree comprises approximately ⅓ of the IFDMA channelization code tree.
