Abstract: A method of scheduling data communication over an uplink. The method enables two or more users seeking to transmit data over the uplink to be scheduled in response to their path loss. The user having the most attractive determined path loss among the two or more users seeking to transmit data over the uplink us scheduled first. Thereafter, the next user having the next most attractive path loss among the remaining users may be subsequently scheduled if the total noise rise leftover is greater than zero. This process repeats so long as or until the total noise rise leftover is about zero.

Abstract: A method of using a generated pilot signal inserted in a CQF slot of an uplink signaling channel to control the transmission power of data information independently of the transmission power of voice information regardless of whether the voice and data information are transmitted simultaneously.

Abstract: An embodiment of the present invention provides a method for improving the capacity of a reverse link by realizing a scheme to effect sharp changes in pilot channel transmit power (PCTP) and data channel to pilot power ratio (DCPR), coordinated with the start of the data channel transmission. The change in pilot power and data channel to pilot power ratio is also applicable to mobiles that use multiple pilots and/or multiple antennas at the transmitter and/or receiver.

Abstract: A wireless data communication system includes a high speed dedicated physical control channel (EU-DPCCH) used with transmissions from a mobile device to support an uplink high speed data channel. In one example the EU-DPCCH has a sub frame structure that is the same as an associated dedicated data channel and a fixed spreading factor. The EU-DPCCH allows communicating control information from the mobile device such as a pilot reference, hybrid automatic repeat request information, and backlog information regarding a buffer of the mobile device.

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 for conveying signaling information of a communication system that uses MIMO antenna systems. To enable a relatively larger amount of information to be conveyed over the communication system and thus exploit the use of the MIMO antenna system, forward link signaling channels are provided where such channels contain swapping information that allow the communication system to retransmit traffic information using any one of the antenna elements of a MIMO system. The forward link signaling channels also contain channel assignment information that indicate which particular groups of channels are available for use by particular users of the communication system.

Abstract: A method of generating coded user ID information that is combined with CRC codes and the result is appended to signaling information. The CRC codes are generated from the signaling information. The resulting codeword is transmitted over shared signaling channels to various users of a communication system. The resulting codeword is such that the likelihood of users attempting to decode codewords not intended for them is significantly reduced.

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.

Abstract: A method for reliably transmitting signaling information is provided. One type of signaling information is transmitted over a primary control channel. The signaling information that is to be transmitted over the primary control channel is defined as a set of particular information. Other signaling information are conveyed over a secondary control channel. Prior to transmission, the information to be conveyed over the secondary channel is scrambled in accordance with a particular scrambling procedure that indicates the information that is to be sent over the primary control channel. The scrambling is thus used to encode the information content of the primary control channel into the information of the secondary control channel thereby further protecting the integrity of the information being conveyed over both control channels.

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.

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.
