Abstract: Embodiments disclosed herein relate to methods and systems for providing adaptive server selection in wireless communications. An access terminal may be configured to determine a forward link quality metric associated with each of a plurality of sectors serviced by a plurality of access points; assign credits to each sector in relation to the forward link quality metric; and change a data source control (DSC) value if the credits accumulated for a non-serving sector at a DSC change boundary is greater than a predetermined threshold, where the non-serving sector and the serving sector for the access terminal belong to different cells. The access terminal may be further configured to change a data rate control (DRC) cover in accordance with the DSC change. The use of DSC may provide an early indication of handoff, thereby allowing the service outage associated with server switching to be substantially reduced.

Abstract: In a multi-carrier access terminal having a transmitter with a single power amplifier, maximum transmission power available for a multi-carrier signal transmitted by the terminal is apportioned among a plurality of carriers on a priority basis. Following apportionment, the carriers are combined into a multi-carrier signal, amplified by the power amplified and transmitted.

Abstract: Methods and apparatus for estimating maximum rate of data and for estimating a transmission power required for transmission of a data with a rate of data in a communication system are disclosed. A terminal determines a quality metric of a communication link, over which data are to be transmitted, and modifies the determined quality metric by a quality metric margin. The terminal then estimates the maximum rate of data in accordance with the modified quality metric. Alternatively, the terminal then estimates transmission power required for transmission of a data with a rate of data in accordance with the rate of data and the modified quality metric. The quality metric margin may be pre-determined or dynamically adjusted. The terminal dynamically adjusts the quality metric margin in accordance with a result of comparison of a transmit power corresponding to the estimated maximum rate of data with an actual transmit power used to transmit the data.

Abstract: Embodiments disclosed herein relate to methods and systems for pilot grouping, route protocols, and scheduling in multi-carrier communication systems. In an embodiment, an access terminal may group a plurality of pilot signals characterized by different frequencies into one or more pilot groups, each pilot grouping being identified by a plurality of parameters (e.g., a PN offset and a group ID). Each pilot group may include pilot signals having substantially the same coverage area. The access terminal may further select a representative pilot signal from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping for effective set management.

Abstract: The present patent application comprises a method and means for demodulating symbols, comprising converting an OFDM symbol from a time domain to a frequency domain, selecting pilot tones, making a soft decision based on received data, and estimating a channel frequency response. In another example, the method and means further comprises selecting guard tones. In another example, the method and means further comprises generating channel estimates for in-band and band-edge pilot tones.

Abstract: Techniques for generating and transmitting packets on multiple links in a wireless communication system are described. In one aspect, a transmitter generates new packets for the multiple links based on the likelihood of each link being available. The transmitter determines the likelihood of each carrier being available based on whether or not there is a pending packet on that carrier and, if yes, the number of subpackets sent for the pending packet. The transmitter generates new packets such that packets for links progressively less likely to be available contain data units with progressively higher sequence numbers. The transmitter determines whether each link is available and sends a packet on each link that is available. In another aspect, the transmitter generates and sends new packets in a manner to ensure in-order transmission. In one design, the transmitter generates new packets for each possible combination of links that might be available.

Abstract: Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.
