摘要： In the absence of a continuous channel from the mobile terminal that incorporates a CRC in each transmitted frame from which the base station can derive a power control signal for feedback to the mobile station for maintaining the mobile station's pilot Eb/N0 level at a desired target that corresponds to a particular frame error rate, the pilot signal received by the base station from the mobile terminal itself is arranged in a frame format. Each pilot frame is compared with an a prioi known transmitted pilot signal bit pattern to determine whether it has been received in error. In response to a comparison of a received pilot frame with the expected known bit pattern of the pilot frame, an error signal is derived, which in the described embodiment is either a step-up or step-down signal that is fed back to the mobile terminal to increase or decrease its transmitted pilot Eb/N0 level, respectively.

摘要： In one embodiment of the method, a base station is configured to divide a coverage area of the base station into sub-coverage areas. Each sub-coverage area has a smaller range of round trip propagation delays than a range of round trip propagation delays for the coverage area of the base station. Each sub-coverage area may have a different range of round trip propagation delays.

摘要： In a UMTS wireless communication system, the enhanced dedicated physical control channel (E-DPCCH) that is usually always transmitted together with the enhanced dedicated physical data channel (E-DPDCH) on the uplink from a UE to a NodeB is instead only transmitted when a predetermined “start criterion” is met and is turned off when a predetermined “stop criterion” is met until a “start criterion” is later met again. The UE starts transmitting E-DPCCH whenever the corresponding E-DPDCH transport format combination is different from the previous one in the same HARQ process or some other “start criterion” is met. Multiple mechanisms can be used to decide when the UE should switch off E-DPCCH transmission after the transport format combination of E-DPDCH has changed.

摘要： The present invention relates to a method of channel estimation comprising two major steps. The first step is the least-squared and minimum mean-square error (MMSE) estimations on the pilot resource elements to generate the channel response estimates at the predefined pilot locations. The second step of the channel estimation, which utilizes the results from the first step to compute the channel response estimates for the remaining resource elements, comprises the following three operations: (i) averaging of each pair of adjacent pilot resource elements in the frequency direction to obtain the channel response estimate of the resource element in the middle of those two pilot resource elements; (ii) MMSE interpolation in the time domain for all the sub-carriers containing pilot signals; and (iii) linear interpolation in the frequency direction for all the sub-carriers not containing any pilot signals.

摘要： A method is provided for controlling communications between a base station and a mobile device. The method comprises enlarging a search window in which a transmission is expected to be received in response to the absence of an external timing signal, such as when the global positioning system (GPS) is shut down. Additionally or alternatively, the method further comprises altering the timing of a received signal relative to a search window, such as by delaying the timing of the received signal to move the signal toward the center of the search window.

摘要： To address the need for new interference cancellation techniques that are able to deliver adequate performance but with reduced processing requirements, various embodiments are described. In some embodiments, a receiving device demodulates and decodes (101) at least one first-group user from a multi-user input signal. This multi-user input signal includes at least one first-group user and at least one second-group user, the first-group users having a shorter transmission time interval (TTI) than the second-group users. The receiving device reconstructs (102) an interference signal for each of the first-group users that were successfully decoded and subtracts (103) each interference signal from the multi-user input signal to generate an interference-canceled signal. The receiving device then demodulates and decodes (104) at least one second-group user using this interference-canceled signal.
