    摘要: 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.

    摘要: The present invention provides a method and an apparatus for wireless communication between a wireless unit and a set of base stations. The method includes signaling the wireless unit about a plurality of transmissions of same packet data from the set of base stations to enable a soft handoff on a forward link. The plurality of transmissions of same packet data having an unsynchronized relationship. The wireless unit may use a detection/demodulation function, which is capable of simultaneously receiving and decoding signals from two or more sectors (base stations). Instead of soft-combining signals received from multiple cell sectors, the wireless unit independently decodes the received signals. Since soft combining of transmissions is avoided, there is no need to synchronize their transmissions of the same data to a particular wireless unit.

    摘要: A system and method for communicating between nodes in a communications network. The network includes nodes that broadcast and receive data packets over a radio channel. The system includes a distributed trunking method that distributes the communications between the nodes over multiple channels. Voice and other data may be broadcast over data channels, while information regarding the availability of the data channels is broadcast over a control channel. Access to the control channel is controlled using a protocol that may include carrier sense multiple access with collision avoidance (CSMA/CA), time division multiple access (TDMA) or a hybrid of CSMA/TDMA.

    摘要: The present invention is a method for selectively providing, on demand, a Quality of Service level to an end user's data transmitted from a base station to a mobile station of a High Data Rate system. In the disclosed method, a data base is established which contains the Quality of Service level selected by a mobile user from a plurality of levels for data to be transmitted from the base station to the mobile station. Using the reverse link, an end user at a mobile notifies the base station that it is ready to receive data and specifies the rate at which the data is to be sent. Upon receipt of the request for data from the mobile terminal, the base station accesses and runs a scheduler which determines which user's data is to be transmitted next. For each end user, the scheduler divides the requested data rate by the average rate of data received by the mobile during a specific interval and then combines by adding or multiplying the result with the Quality of Service level requested by the end user for data. The end user that has the greatest final result is normally selected to next receive data. The scheduler then conditions the base station to transmit data to the identified mobile station at the requested rate and selected Quality of Service level.

    摘要: A method and apparatus for estimating the initial power level and transmission rate of a burst on a secondary channel when the secondary channel is on fewer legs of a handoff, such as a soft or softer handoff, than the primary channel. In accordance with the present invention, the initial power level of the burst transmitted over a current secondary channel on a particular leg(s) is a function of a power level of a previous burst transmitted over a previous secondary channel on the identical leg(s) as the current secondary channel. For example, the initial power level of the burst can be based on the power level at the end of the previous burst shortly prior to the termination of the previous burst, where the termination of the previous burst was within a predetermined time interval of the start of the burst. Optionally, the initial power level of a burst can also be additionally adjusted based on characteristics of the communication link of the primary channel, the previous secondary channel, and the current secondary channel. The transmission rate may then be adjusted based on the initial power level determined as described above to obtain a more efficient transmission rate.

    摘要: A communications system includes a base station and a plurality of remote stations wirelessly communicating with the base station and transmitting a requested service rate to the base station. The base station allocates a next transmission of data to the remote stations based on a scheduling operation. The scheduling operation includes determining an average service rate for each remote station and determining a priority value for each remote station based on the requested service rate and average service rate. In allocating the next transmission of data, at least one of the average service rate and the priority value is modified to thereby control data throughput of the communications system.

    摘要: A method and communication device for media access control feedback over a packet channel divided in channel time slots is provided. The channel time slots are divided into sub-channel time slots. A packet channel feedback field associated with each sub-channel time slot is defined. Acknowledgments are indicated using the packet channel feedback field. An active mobile identity associated with an active mobile station may be assigned which would then be included in the packet channel feedback field. A plurality of active mobile identities may be assigned and some of the active mobile identities may be reserved for special functions. The assigned active mobile identity is used, among other things, to identify an active mobile station to receive packet data signals. The active mobility identity is invalidated after one transaction of packet data signals or invalidated after a short number of such transactions. One or more of the assigned active mobile identities may be used to indicate a time slot assignment for the active mobile station. A sub-channel feedback field in the packet channel feedback field is used to indicate acknowledgments. A sub-channel assignment field in the packet channel feedback field is used to indicate time slot assignments. The sub-channel assignment field is substantially independent of the sub-channel feedback field.
