    Abstract: A method for providing an assignment acknowledgement is provided. The method comprises: decoding forward link control channel data blocks according to parameters provided by an overhead channel message; receiving forward link packet data at an access terminal (AT) via a data channel; identifying an offset which defines that a certain number of subpackets of the packet data have been transmitted before the assignment acknowledgement is to be transmitted; and transmitting the assignment acknowledgement according to the offset to indicate successful decoding of one of the control channel data blocks only if the packet data has not been acknowledged.

  • Patent number: 7787552
    Abstract: A wireless communication network is configured to provide distributed diversity transmissions, wherein different diversity-coded versions of the same information signal are transmitted from each of two or more network sectors. The diversity-coded versions of the information signal are based on space-time or space-frequency codes, and the information signal may comprise a dedicated channel signal targeted to an individual user or a broadcast signal targeted to one or more users. Thus, spaced-apart network transmitters, which may be located at the same cell site, or at different cell sites, are configured to transmit diversity-coded versions of a given information signal and, in this manner, the advantages of space-time and/or space frequency transmission coding may be applied across multiple sectors of a communication network.

  • Patent number: 7738901
    Abstract: A communication transceiver transmits a power-controlled first signal responsive to received power control commands and transmits one or more additional signals at variable power gains relative to the transmit power of the first signal based on reception quality feedback received for the additional signals. Thus, a mobile station may transmit a traffic channel at a variable power gain relative to its pilot signal power and vary that gain responsive to reception quality feedback received by it for the traffic signal. Of course, the mobile station may float more than one traffic channel using variable gains and may use different variable gains for each one. Further, the mobile station may float one or more non-pilot channels relative to the pilot or relative to another channel, while transmitting one or more fixed gain channels. Similar variable power gain may be employed at network base stations for forward link signals.

  • Patent number: 7701910
    Abstract: A reference signal including a quality indication is injected into the reverse link signal received at a base station. The transmit power of the reference signal is controlled by the base station through reverse link power control, and the base station estimates the reverse link load from the transmit power of the reference signal. As the load increases, the transmit power must increase to overcome interference. The reference signal may be generated by a signal generator within the base station; by a mobile station hardwired to the base station; or by a mobile station proximate the base station, sending the reference signal over the air interface. The reverse link load may be estimated directly from reference signal transmit power, or from the reference signal transmit power minus a minimum reference signal transmit power in the absence of interference.

  • Publication number: 20100015978
    Abstract: Systems and methodologies are described that facilitate improved multi-mode system selection in a wireless communication system. As described herein, various techniques can be utilized to synthesize system databases corresponding to disparate groups of radio access technologies (RATs), such as a Public Land Mobile Network (PLMN) list and/or a Preferred Roaming List (PRL), with one or more overlay databases and associated location information to generate a multi-mode list of preferred systems. As described herein, a preferred system listing can be constructed to leverage fine granularity of information in one or more databases while still supporting databases with coarser information. Techniques are additionally described herein for augmenting and/or grouping one or more overlay databases to facilitate a higher available granularity of information for various RATs than that provided in system databases corresponding to the RATs.
