In one embodiment of managing the use of channelization codes during soft handoff of a mobile station from a transferring network station to a candidate network station, a determination is made as to whether a field associated with an existing channelization code used by the candidate network station is unused and meets timing criteria associated with a corresponding field received by the mobile station from the transferring network station. Based on this determination, a channelization code for use by the candidate network station in communicating with the mobile station is assigned.

Method of managing use of channelization codes during soft handoff

In one embodiment, a target scheduling grant for a user is generated based on the uplink resource consumed by a plurality of users, and a scheduling grant for a user is generated based on the target scheduling grant and the uplink resource consumed by the user. More specifically, in one embodiment, a scheduling grant is generated for the user based on the target scheduling grant, the uplink resource consumed by the user, and a reference scheduling grant.

Method of scheduling uplink resource in a wireless communication system

In a method of avoiding multiple detection of the same random access channel (RACH) preamble in a wireless communication system, and within a given set of access slots, a given sub-set of available preamble signatures corresponding to a RACH preamble of a user may be detected, so as to avoid multiple RACH preamble detection in a given access slot. Another method may be directed to switching operations of a base station in a communication network. Base station operations may be switched back and forth between multi-sector/single cell operations and single sector/multi-cell operations without changing an existing antenna configuration.
