摘要： In a floor control system for a network, a floor control server controls a floor-based application for communications between multiple participant terminals. The server carries out a floor determination process that includes an adaptive waiting function. Upon receiving an initial floor request message, the server waits for additional requests before determining the floor winner. The wait time is a function of the floor request load. When the system is lightly loaded, the wait time is generally small. For heavier request loads, the wait time is generally longer, to ensure that a reasonable number of requests are received before awarding the floor. The wait time may be limited by a maximum wait time, which is a function of the floor request load. If a designated number of floor requests is received before the maximum wait time expires, a temporary floor winner is granted the floor if its priority is sufficiently high.

摘要： Various methods and devices are provided to address the need for improved cooperation-based signal processing. In a first method, network equipment determines (801) a set of dominant interferers for a wireless transmission and requests (802) user-plane data corresponding to each dominant interferer in the set of dominant interferers. The network equipment then processes (803) a received signal corresponding to the wireless transmission to extract the information transmitted. This processing uses at least some user-plane data corresponding to at least one dominant interferer in the set of dominant interferers.

摘要： Methods and systems for generating a variable spacing pulse position modulated (VSPPM) signal for transmission across an ultra-wideband communications channel. The variable pulse position modulated spread spectrum signal is created by encoding every M input data bits from an input data stream into a symbol consisting of Nc chips. Each chip is divided into 2M sub-chips and each sub-chip is further divided into Np time slots. A pulse is transmitted for each chip in the symbol. During each chip period, the pulse is placed in the sub-chip corresponding to the binary M-tuple (or symbol) value. A time hopping code sequence consisting of Nc elements with a one-to-one chip association is then applied to each symbol so that the position of each pulse is shifted to the appropriate time slot that corresponds to the time hopping code value.

摘要： Various methods and network nodes (e.g., base stations or base transceiver nodes) are provided to address the need for enhanced uplink performance. In a first method, a virtual soft handoff network node receives (501), from a serving network node, information related to uplink communications of user equipment (UE) served by the serving network node, wherein a soft handoff is not established between the virtual soft handoff network node and the UE. The virtual soft handoff network node receives (502) uplink communications between the UE and the serving network node and processes (503) the uplink communications to determine decoded uplink data from the UE. In a second method, a serving network node sends (401) to a virtual soft handoff network node, information related to uplink communications of user equipment (UE), the UE being served by the serving network node but not in soft handoff with the virtual soft handoff network node.

摘要： In a wireless communications system which hops from frequency to frequency, rather than hopping according to a fixed dwell interval and a pre-determined pseudo-random hop sequence, a quality-based frequency hopping methodology is defined in which a new frequency is hopped to when the channel quality on the current frequency degrades based on the measured value or values of one or more predetermined metrics that are associated with channel quality. When triggered to hop to a next frequency, the hop-to-frequency may be the next frequency in the pseudo-random hop sequence known to both the transmitter and receiver or, in order to improve the reliability of communications, may be determined based on channel quality measurements on different potential hop-to-frequencies.
