摘要： Techniques for expanding the set of addressable interfering signals in an interference cancelling receiver are described, where the task of control message detection from interfering cells is integrated in an iterative receiver process where increasingly better a priori information on the received data signals from the previous iteration is used to detect additional control messages and successively grow the set of interfering signals included in the receiver's interference mitigation processing. In an example method, first estimated symbols for a desired signal are generated. A control channel corresponding to a first interfering signal is detected, where said detecting is based on the first estimated symbols. Signal characteristics information for the first interfering signal is then derived from the detected control channel signal, and used to generate second estimated symbols for the desired signal, using an interference-mitigation technique to mitigate the effects of the interfering signal.

摘要： A wireless communication transmitter configured to transmit a multi- carrier signal, the multi-carrier signal being an aggregation of two or more separately modulated carriers occupying distinct frequency regions is operated by obtaining a baseline multi-carrier metric indicative of an amount by which a multi-carrier signal's maximum transmit power should be reduced from a predetermined nominal maximum to satisfy a predetermined out-of-band emission requirement when different scrambling codes are used on all carriers that are combined to create the multi-carrier signal. A compensating metric adjustment value that compensates for an estimation error that results from use of a same scrambling code on two or more of the carriers is estimated. A final multi-carrier metric is obtained by adjusting the baseline metric by an amount based on the compensating metric adjustment value when the same scrambling code is used on the two or more of the carriers.

摘要： Methods and apparatus are provided for detecting the radio access technology (RAT) employed in a received signal prior to performing a cell search. The RAT detection method may be used to identify the most likely RAT employed for each candidate frequency identified in an initial frequency scan. Once the most likely RAT is identified, the mobile communication device can then attempt synchronization according to the procedures for the most likely RAT. Identifying the RAT prior to the cell search reduces the number of synchronization attempts and, consequently, the time needed to perform the cell search.

摘要： Methods and apparatus are disclosed for reducing mobile terminal energy consumption during data transmissions by allocating link resources and adapting link parameters in an energy-aware manner, based on throughput requirements and prevailing channel conditions. A combination of transmit parameters that includes a transmit channelization scheme and is designed to minimize the total energy consumed during data transmission is selected based on a throughput requirement and one or more channel conditions associated with the data transmission. The channelization scheme includes a number of subchannels to be used and subchannel configuration parameters for each subchannel, such as spreading codes, spreading factors, and subchannel power levels. The combination of transmit parameters may also include a modulation format,\ coding scheme, and transmit power setting, as well as parameters relating to multiple-antenna transmit schemes.

摘要： A method in a wireless communication network 100 for assisting a user equipment 130 to receive signals from a target access node 122. The wireless communication network 100 comprises the target access node 122, the user equipment 130 and a serving access node 120 serving the user equipment 130. The serving access node 120 sends information about time instances to the user equipment 130. The time instances are scheduled for sending signals from the target access node 122 in a beam direction 220 towards the user equipments 130. The time instances may be determined in the target access node 122 based on its own position and a position of the user equipment 130 and/or a beam direction 210 of the serving access node. The time instances may also be determined in the serving access node 120 based on its own position and a schedule of the target access node 122 on beam directions versus transmission times. The user equipment 130 receives signals from the target access node 122 during the time instances indicated in the received information. In this way, leaving more time for the user equipment to receive data or signal from the serving access node 120. As a result, the throughput of the wireless communication network is increased and improved.
