Abstract: Data communication includes an estimate of packet error rate that is useful, for example, when there is insufficient data transmission to provide a direct measurement of packet error rate. At least one pilot channel output provides a basis to determine an estimated packet error rate. One example includes using a pilot channel ratio of an energy-per-chip to a noise spectrum density. Another example includes using a pilot symbol error rate from the pilot channel as the basis for determining the traffic channel packet error rate.

Abstract: The present invention provides a method for detecting a reverse rate indicator channel. The method may include accessing first encoded information indicative of a data rate and a first sub-packet identifier associated with a sub-packet, accessing second encoded information indicative of the data rate and a second sub-packet identifier associated with the sub-packet, and modifying the second encoded information. The method may also include combining the first encoded information and the modified second encoded information, and decoding the combined first and modified second encoded information.

Abstract: Outer loop power control for a traffic channel includes using at least one output from another channel to determine an appropriate control threshold such as a signal-to-noise ratio when selected channel conditions exist. One example traffic channel condition comprises having insufficient data transmission to provide a direct measurement of packet error rate. Another example traffic channel condition used to determine when to use the other channel output is a transmission mode on the traffic channel. An example output used for setting the control threshold is a chip energy to noise ratio of a pilot channel associated with the traffic channel.

Abstract: The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.

One embodiment of the method includes providing, to a mobile unit, at least one message including information indicative of at least one parameter for configuring at least one response to said at least one message for transmission over an access channel.

The cellular network includes a plurality of mobile stations that wirelessly communicate with a base station over a reverse link, using a CDMA or similar communications protocol. A joint access and traffic overload control module creates an access channel load relief plan, a traffic channel load relief plan and then relieves the total loading of the reverse link based upon both the access channel load relief plan and the traffic channel load relief plan.

Abstract: The present invention provides a method and an apparatus for controlling transmission power of a wireless unit. The method includes providing a power control in a reverse link to a network that transmits data on a traffic channel in a bursty manner based on a performance metric of a channel with continuous transmission of other data than on the traffic channel. To provide a power control in a reverse link of a spread-spectrum wireless data network a method and an apparatus are provided for combining performance of a quality of service from at least one of a first quality feedback channel and a second quality feedback channel with that of a pilot channel and providing an outer-loop power control in said reverse link for a wireless communication on a traffic channel based on said combined performance of the quality of service to control transmission power of a wireless unit.

Abstract: In the method, an average user throughout over all active users is computed, and each user's user perceived throughput is compared against the computed average throughout. Based on the comparison, the scheduling of the plurality of users is prioritized. In an embodiment, a priority adjustment factor is applied to each user to prioritize the scheduling of users to receive a data transmission. The priority adjustment factor is determined based in part on an update function. The update function is proportional to a calculated difference between each user's user perceived throughput and the average user throughput. Based on the sign of the update function, the priority adjustment factor is either incremented or decremented, and hence, prioritization of users is ordered. The output of the scheduler is user identifying information that informs the base station to transmit data in a current time slot to the identified user determined as the highest priority user by the scheduling method.

Abstract: The present invention provides a method and an apparatus for controlling a radio frequency resource between a first and a second wireless unit and a base station to provide overload control of the radio frequency resource based on an estimate thereof. For example, when feedback information is unavailable for the radio frequency resource at the base station. The method includes estimating the radio frequency resource used by the first and second wireless units in a wireless data network. The method further includes providing an overload control at the base station based on the estimated radio frequency resource. Based on this estimated radio frequency resource, a command may be issued by the base station on a reverse link. For example, a rise over thermal resource may be estimated to issue a rate control command to a wireless unit. By providing a desired timely rate control command on the reverse link, the base station may control a data rate of the wireless unit, maximizing throughput of the reverse link.

Abstract: A method for determining rise over thermal for a base station in a wireless communications system is provided. The method comprises receiving a first and second diversity signal, measuring the signal strength of the first and second diversity signals, and estimating the noise floor for the first and second diversity signals. The signal strength rise is determined for the first and second diversity signals based on the measured signal strength and estimated noise floor of the first and second diversity signals respectively. The rise over thermal is then determined based on the determined signal strength rise of the first and second diversity signals.

Abstract: A wireless data network distinguishes among different users connected to the network and associates each user with a service class that offers a selected level of service. The base station in the network queries the user for its unique user identification code and accesses a database linking user identification codes with their corresponding services classes. The network then controls the service level given to that user based on the service class associated with the user identification code. The user identification code can be sent to the network via existing fields in current standards.
