摘要： Apparatus and method for reducing an air interface load in a communication network. A base station is provided with a receiver adapted to receive signals from a terminal via a Dedicated Physical Control Channel (DPCCH) and a second control channel. A measuring unit measures a signal to interference ratio (SIR) of the DPCCH. An effective SIR determining unit determines an effective SIR on the basis of the measured SIR of the DPCCH and an estimate of the SIR of the second control channel. A comparison unit compares the effective SIR with a target SIR, and a power determination unit determines a power control command for controlling power usage for the DPCCH on the basis of the comparison. A transmitter sends a message to the terminal, the message including the power control command. The invention allows the DPCCH power (or DPCCH SIR) operating point to be maintained at a low level.

摘要： In a wireless communication network UE, an estimated signal to interference and noise ratio (SINR) is calculated for each potential transmission mode, and is reduced by a calculated SINR back-off value in response to errors detected in decoding data in each of a plurality of data streams. A Channel Quality Indicator CQI is then generated based on the reduced SINRs. Reducing the SINR estimates in the presence of known data errors allows a UE to more accurately track a target BLER.

摘要： A downlink Channel Quality Indicator (CQI) is estimated in two steps. Initially, one or more subsets of received reference symbols are selected. If the transmitter may transmit signals in one or more of two or more frequency bands, optimal frequency bands are selected based on a first subset of reference symbols. If the transmitter may transmit using one of two or more VACs, an optimal VAC is selected based on the first or a second subset of reference symbols. An SINR is subsequently calculated for the selected frequency band and VAC combination, based on more than the subset(s) of reference symbols.
摘要翻译：在两个步骤中估计下行链路信道质量指示符（CQI）。首先，选择接收到的参考符号的一个或多个子集。如果发射机可以在两个或更多个频带中的一个或多个频带中传输信号，则基于参考符号的第一子集来选择最佳频带。如果发射机可以使用两个或更多个VAC中的一个发射，则基于参考符号的第一或第二子集选择最佳VAC。基于多于参考符号的子集，随后针对所选择的频带和VAC组合计算SINR。
