Abstract: A system and a method of controlling transmitter power in a wireless communication system in which user data is processed as a multirate signal having a rate N(t) and in which the user data signal having rate N(t) for transmission. The transmission power is adjusted on a relatively slow basis based on quality of data received by a receiver of the transmitted data. The transmitter power is determined as a function of N(t)/M(t) such that a change in the data rate in the multiple channels or the rate of the transmission data signal is compensated in advance of a quality of data based adjustment associated with such data rate change. Preferably, the user data signal having rate N(t) is converted into the transmission data signal having the faster rate M(t) by repeating selected data bits whereby the energy per bit to noise spectrum density ratio is increased in the transmission data signal.

Abstract: A time division duplex communication system using code division multiple access transmits a plurality of data signals over a shared spectrum in a time slot. A combined signal is received over the shared spectrum in the time slot. The plurality of data signals are grouped into a plurality of groups. The combined signal is matched filtered based on symbol responses associated with the data signals of one of the groups. Data from each data signal in this one group is jointly detected. An interference signal is constructed based on the detected data, of this one group. The constructed interference signal is subtracted from the combined signal. Data from the other groups is detected by processing the subtracted signal.

Abstract: Resource units are assigned within a cell of a wireless time division duplex communication system using code division multiple access. Each resource units is associated with a time slot and a code. For selected ones of the cell's resource units, the code interference level is measured during that unit's time slot and using that unit's code. The code interference level is compared to a threshold to determine whether that unit has an acceptable code interference level. Resource units are assigned to communications out of the unit's having acceptable interference levels.

Abstract: A cellular radio system in which a base station receiver can receive, on the reverse link, data from a mobile terminal in four modes. In the first mode, the mobile terminal sends an independent user pilot on the reverse link and the user data channel is synchronized to this independent user pilot. In the second mode, the mobile terminal slaves its user pilot to the received base station's pilot and the user data channel is synchronized with the user pilot. In the third mode, the mobile terminal slaves its user pilot to the received base station pilot, but the user data channel operates in the orthogonal mode using the ranging information received from the base station. The phase relationship between the user pilot channel and the user data channel is calibrated. The user pilot carrier is also the carrier for the user data channel and can be used as the carrier reference for detecting the user data channel. In the fourth mode, the slaved pilot implementation of mode three is used for acquisition but, after acquisition, the user pilot code is phase shifted to be synchronous with the user data channel, making it an orthogonal channel.

Abstract: PROBLEM TO BE SOLVED: To achieve power savings by turning off all or some of the baseband processing for codes and timeslots that have not been transmitted due to full DTX. SOLUTION: When full DTX is detected by reception of a Special Burst (SB), the receiver is turned off for all timeslots and frames(step 20) for the duration of the Special Burst Scheduling Period (SBSP). The transmitter schedules transmissions following any idle period to start on the boundary of the SBSP. The receiver determines the SBSP and if the transmitter initiates transmissions according to SBSP by reception of several initial full DTX cycles. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To conduct a data processing method different from a conventional UTRAN processing method. SOLUTION: The address mapping of bits in a physical channel buffer 84 is determined from the address of bits in a first interleaver buffer 82. Addresses of the physical channel buffer 84 are determined corresponding to addresses of the bits after rate matching, bit scrambling, second interleaving and physical channel mapping in a rate matching engine 88. The bits are directly read from the first interleaver buffer 82 and written to the physical channel buffer 84 using the determined addresses of the physical channel buffer 84.

Abstract: PROBLEM TO BE SOLVED: To surely converge an initial target SIR of NRT data into a desired target SIR, by utilizing a Temp-DCH allocation duration as an additional parameter for strengthening power control. SOLUTION: A method, system, and components for outer loop power control 500, particularly useful for non-real time data services, uses data transmitted in many short bursts of short duration, called Temp-DCH allocations (509). A target metric, preferably target SIR (502), is adjusted with differing step-up and step-down target metric adjustments. The initial target SIR (502) and the transient step size for target SIR adjustment (505-507) are determined in a dynamical way, in the outer loop power control for each Temp-DCH allocation (509) of non-realtime data.

SOLUTION: The spread code sequence generating apparatus includes a plurality of stages including a first stage and a final stage, wherein each stage has: a linear feedback shift register (LFSR) for demarcating a tap for generating a tap signal, applying a prescribed tap signal group to a logic circuit where the signals are composed and a feedback spread signal for input to the first stage is produced; a memory means being a first memory means for storing a plurality of spread code seeds, connected to the LFSR, and for respectively transferring each of a prescribed set of the spread code sequences of the spread code seed to be selected in response to a load signal; and a code generating unit control means for selecting one of a plurality of the spread code seeds and producing the load signal corresponding to the spread code. The LFSR transfers the tap signal from one stage to the next, transfers the feedback spread code value to the first stage, and demarcates a master spread code sequence by each of consecutive tap signal values of the final stage.
