Abstract: The present invention provides for wireless terminal and a method in a wireless terminal for use in a location determination approach using time of arrival estimates between the wireless terminal and a plurality of base stations in a cellular network. The method includes receiving assistance data from a serving base station for use in receiving a position reference signal used to determine a time of arrival of one or more respective position reference signals from the plurality of base stations relative to a time reference, wherein the assistance data includes a list of base stations, each base station included in the list to be one of used or excluded from use as part of the plurality of base stations for receiving the position reference signal and determining the time of arrival estimate for the received position reference signal. The position reference signal is then received for each of the plurality of base stations, where for each of the plurality of base stations a time of arrival estimate is determined for each of the respective received position reference signals. The time of arrival estimates for each of the plurality of base stations is then forwarded to a location determination entity.

Abstract: A communication system having spreading code resources (11) (such as, for example, Walsh codes), and upon providing (12) an initial quantity of those spreading code resources to support a voice communication by a given mobile station, then determines (13) whether to alter that initial allocation during that voice communication. For example, when the voice communication for this mobile station does not actively comprise speech, a determination can be made to allocate a reduced allotment of the spreading code resources. The system then switches (14) the new allocation of spreading code resources for the initial allocation and the mobile station continues its voice communication using the new (increased or decreased) quantity of spreading code resources.
