Abstract: Embodiments disclosed herein address the need in the art for reduced overhead control with the ability to adjust transmission rates as necessary. In one aspect, a first signal indicates an acknowledgement of a decoded subpacket and whether or not a rate control command is generated, and a second signal conditionally indicates the rate control command when one is generated. In another aspect, a grant may be generated concurrently with the acknowledgement. In yet another aspect, a mobile station monitors the first signal, conditionally monitors the second signal as indicated by the first signal, and may monitor a third signal comprising a grant. In yet another aspect, one or more base stations transmit one or more of the various signals. Various other aspects are also presented. These aspects have the benefit of providing the flexibility of grant-based control while utilizing lower overhead when rate control commands are used, thus increasing system utilization, increasing capacity and throughput.

Abstract: A remote station for a wireless communication system including a base station is disclosed. The remote station includes a front end structure configured to receive packet data in parallel on a subset of carrier frequencies. Each packet data is preceded by a header field for identifying the remote station as the recipient of the packet data and the subset of carrier frequencies is based on a set of a corresponding number of multiple carrier frequencies.

Abstract: Forward link transmission power to a user terminal in a wireless communications system having a plurality of beams is controlled by identifying the location of a user terminal within one of the plurality of beams, and setting the forward link transmission power in response to the identified user terminal location. Identifying user terminal location may include receiving from the user terminal multiple signal power measurements, such as pilot signal measurements. From these measurements, a difference is calculated between a first of the signal power measurements that corresponds to a home beam and each of the other signal power measurements. If the largest of the calculated differences is greater than a predetermined threshold, it is concluded that the user terminal is within a beam central region. However, if the largest of the calculated differences is less than or equal to the predetermined threshold, then it is concluded that the user terminal is within a beam crossover region.

Abstract: A mobile wireless terminal (MWT) receives IP packets destined for a ground network in a predetermined sequence order. The MWT fragments each of the IP packets into many smaller packet fragments, appends identifying information to each of the packet fragments, and transmits the packet fragments in parallel with one another over concurrently operating satellite channels. A receiving station receives the packet fragments transmitted by the MWT. The receiving station forwards the received packet fragments to a ground controller over a network connection, based on the identifying information appended to the packet fragments. The ground controller combines the packet fragments into reconstructed IP packets based on the identifying information appended to the fragments. The ground controller also sequences the reconstructed IP packets in the predetermined sequence order based on the identifying information. The ground controller forwards the reconstructed IP packets in the correct sequence order to the destination ground network. The same sequence of events occur in the opposite direction as well i.e., from the ground controller to the MWT.

Abstract: A method and apparatus provides for efficient use of communication resources in a CDMA communication system (100) by selecting, at a time prior to a first time period (401), a first mobile station to receive transmission during the first time period (401) on a downlink shared channel, and selecting, at a time prior to the first time period (401), a second mobile station to receive transmission during a second time period (402) on the downlink shared channel. Transmission power level of a downlink shared control channel is determined for transmission to the second mobile station during an overlapping time period (403) with the first time period (401), and the transmission power level of the downlink shared channel for transmission during the first time period (401) is determined based on at least the determined transmission power level of the downlink shared control channel during the overlapping time period (403).

Abstract: Systems and methods for communicating control data for multiple physical data channels by transmitting control information for a first physical data channel on a physical control channel and combining the control information with information for a logical data channel and transmitting the combined information on a single physical data channel. In one embodiment, a method includes encoding and multiplexing data for a first data channel with control information for a second data channel, transmitting the multiplexed data on the first data channel, transmitting second data on the second data channel, and transmitting the control information for the first data channel on a control channel. The multiplexed data is then decoded using the control information from the control channel and demultiplexed. The demultiplexed control information for the second data channel is then used to decode the data on the second data channel.
