摘要： A method (400) and apparatus (501) provide for rapid power control based on a quality related value, e.g. channel quality indicator (CQI) value. A transmit power level can be derived from a CQI value received according to a time period, e.g. corresponding to 500 Hz. A first predicted value can be predicted based on the CQI value, at a first time within the time period and a power adjustment value can be determined based on the CQI value as well as the first predicted value at a rate that exceeds the rate of receiving the CQI values. Note that other predicted values for or corresponding to the CQI value can be predicted at other times within the time period and that power adjustment values can be determined through interpolation between predicted values for any time within the period.

摘要： Various embodiments are described which can serve to mitigate interference between the control channel signaling of adjacent sectors/cells. Potentially, these techniques may have the benefit of reducing the system resource drain caused by control channels, particularly control channels in high frequency-reuse, OFDMA systems. A transmitting device (101) transmits primary control channel information to a plurality of user devices (102). The primary control channel information includes an indication that a first OFDMA resource region (e.g., 320 or 330) is assigned to at least one user device of the plurality of user devices. The transmitting device correspondingly transmits secondary control channel information to the at least one user device using the first OFDMA resource region.

摘要： A base station (101) of a cellular communication system (100) comprises a receiver (105) and a channel quality processor (111) which receive channel quality indications from a communication unit (103). The base station (101) further comprises a transmitter (107) for transmitting signals to the communication unit (103). A first power control processor (115) controls the transmit power in response to a first power control mode of operation and a second power control processor (117) controls the transmit power in response to the second power control mode of operation. A rate processor (113) determines a rate of change indication for the channel quality indications and a selector (119) selects between the first power control mode and the second power control mode in response to the rate of change indication. The power control mode of operation may be modified to suit the current channel variations of the communication channel. The invention may be applicable to an HSDPA service in a UMTS cellular communication system.

摘要： A user equipment (UE) operating in an Orthogonal Frequency Division Multiplexing communication system transmits Layer 1 and Layer 2 user data non-associated and user data associated control signaling on an uplink by puncturing user data information with the user data non-associated and user data associated control signaling to produce a data stream wherein the control signaling and user data information are multiplexed. The UE then conveys the punctured data stream to a radio access network via an air interface. The communication system further provides for a selection of a coding and modulation for the control signaling based on a modulation and coding scheme of the user data and a transmission scheme that is applied for transmission of the user data information over the air-interface.
