摘要： A relay node is operated in a communication system wherein the relay node communicates with a communication system node via a first link and communicates with user equipment (UE) via a second link. The relay node detects whether a collision between its own uplink transmission on the first link and receipt of the user's transmission on the second link at a future time instant is expected to occur, wherein the collision will interfere with the relay node's ability to receive the UE's transmission. If so, then, the relay node selects and executes one of a plurality of interference averting measures, selection being based at least in part on what type of information is expected to be transmitted and received on the respective first and second links. First and second interference averting measures comprise refraining from or proceeding with transmission of some information to the communication system node.

摘要： An Orthogonal Frequency Division Multiplexing (OFDM) symbol for transmission from a non-reference transceiver to a user equipment (UE) in a mobile communication system is generated by ascertaining a general timing for transmission of OFDM symbols, wherein the general timing is associated with a reference transceiver. A UE timing relative to the general timing is ascertained. An initial resource element (RE) value is adjusted by a pre-compensating amount to obtain a pre-compensated RE value, wherein the pre-compensating amount is based on the UE timing relative to the general timing. The pre-compensated resource element value is supplied as one of a plurality of values to be transmitted. An IFFT is performed on the plurality of values to be transmitted to obtain pre-compensated initial signal information. A cyclic prefix is appended to the pre-compensated initial signal information to form an OFDM symbol for transmission from the non-reference transceiver to the UE.

摘要： A multi-branch OFDM receiver combines diversity signals received over different receiver branches using interference rejection combining. The receiver generates first channel estimates associated with a serving base station, second channel estimates associated with at least one non-serving base station, and a time offset between the serving base station and non-serving base station. The receiver computes a noise covariance matrix based on the second channel estimates and the time offset, and then combines the diversity signals received over different branches using the first channel estimates and the noise covariance matrix.

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： A radio receiver adapted to alternatively receive data over a communication channel in a first mode and a second mode. The second mode facilitates reception of data at higher data rates than the first mode. The radio receiver comprises a signal-processing unit and a control unit. The signal processing unit is adapted to determine a quality condition of the communication channel. The control unit is adapted to determine, based on the quality condition, whether the communication channel facilitates operation in the second mode and assess at least one configuration condition, one of the at least one configuration condition being that the communication channel is determined to facilitate operation in the second mode. The control unit is further adapted to configure the radio receiver to operate in the second mode when all of at least one configuration condition are fulfilled or to operate in the first mode otherwise. A method for controlling the radio receiver is also disclosed.

摘要： A method and apparatus that utilizes the synchronization channel (SCH) by the user equipment (UE) to obtain time synchronization information and to perform cell search. In order to perform the SCH detection, only a correlation between the known SCH signal and the received sequence is needed, hence the FFT is not involved in the synchronization step. Typically the SCH and pilot symbols are transmitted with a constant power which is the same for all base stations. Hence, based on the serving cell (SC) SCH and pilot symbols, the power relation between these signals is estimated and the ratio applied when performing time synchronization to other cells (i.e. correlation the received sequence with the SCH from that particular NC) to estimate the pilot signal strength for the NB cell.

摘要： Methods and apparatus are disclosed for reducing mobile terminal energy consumption during data transmissions by allocating resources and adapting link parameters in an energy-aware manner, based on throughput requirements and prevailing signal propagation conditions. A combination of transmit parameters designed to minimize the total energy consumed during data transmission is selected based on a throughput requirement and a path loss associated with a data transmission by a mobile terminal. The combination of transmit parameters includes a bandwidth allocation and may also include a modulation format, coding scheme, and transmit power setting, as well as parameters relating to multiple-antenna transmit schemes. The bandwidth allocation may correspond to a number of sub-carriers of an OFDM signal, or may correspond to a number of resource blocks in an SC-FDMA signal.
