    Abstract: Efficient data communication in wireless communication system is provided by using centralized control of data communications, such as packet switched services, over the uplink channel (mobile station (MS) to base station (BS)). A multiple access protocol is used where packet data mobile stations make requests for uplink channel resources. The request messages transmitted by the MSs inform the BS of service parameters. Examples of such service parameters are available transmit power at the MS, the amount of data to transmit and Quality of Service (QoS). The BS then processes the received request messages and performs interference management calculations to determine the portion of the BS's receive power budget that can be allocated to the data user requesting service. These calculations are used to control the amount of interference seen at the base station, to assign a data rate to the user and to aid scheduling algorithms in computing service order priorities. Any scheduling algorithm may be used; for example, scheduling may be based on the amount of data to be transmitted, the age of the data or the service priority associated with the mobile station. The interference control is used to prevent the occurrence of catastrophic levels of interference while maximizing the utilization of resources on the uplink.

    Abstract: Data rate determination is provided in a system where the available power fraction and available Walsh codes in each active leg are dynamically changing over time. This method adapts the rate (modulation and coding) based on the combined resource (power & code space) levels seen at each cell. The method results in maximization of the rate supportable by each cell given their resource constrained situation while meeting the constraints of target packet or frame error rate and orthogonality. Furthermore, improved fast cell selection by the mobile results due to this approach that is based on knowledge of combined resource (power & code space) levels across the cells in the active set.

    Abstract: A prior message is used to identify groups of messages that may be used for transmission. The groups of messages contain different numbers of messages, so as a result, messages from smaller groups may be represented using less bits than messages from larger groups. The smallest group contains messages with the highest probability of being sent; therefore, the probability of using a message represented by a smaller number of bits is maximized. Messages from different groups are transmitted at different power levels to enable a receiver to determine the message group. As a result, a receiver uses the prior message, the power level associated with a received message and the received message bits to identify a message. In another embodiment, a known or current system state, rather than a prior message, is used to identify groups of messages that may be used for transmitting or receiving.

    Abstract: A system and method for wireless communication includes multiplexing an EUDC downlink control channel so that it is transmitted like a downlink dedicated channel (DL-DPCH). The EUDC downlink control channel can be multiplexed with the DL-DPCH by code or by both code and time. The EUDC downlink control channel may be multiplexed with a downlink dedicated physical data channel (DL-DPDCH), a downlink dedicated physical control channel (DL-DPCCH), or both. In one embodiment, the EUDC downlink control channel is multiplexed by adding a multicode channel to a current DL-DPCH and treating the EUDC downlink control channel as a dedicated channel with power control functionality.

    Abstract: A method of providing an efficient channel structure for a communication system that uses codes to define its communication channels. Available codes form a code space that is equally divided into M tiers based on load conditions; M is an integer equal to 1 or greater. Information is scheduled to be transmitted during a particular time slot and is assigned to a particular tier. The information is transmitted during the scheduled time slot using all of the codes of the assigned tier.
