    摘要： A method for reducing a signal-to-noise ratio requirement in a time division multiple access (TDMA) link of a mobile network. The network includes a first node and a second node. The method includes receiving at the first node, an initial TDMA signal burst transmitted from the second node, and determining link state variables, thereby synchronizing the first node to the TDMA signal burst. The method further includes tracking the link state variables between the initial TDMA signal burst and subsequent receptions of TDMA signal bursts from the second node at the first node.

    摘要： In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit (101) in base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit (103) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

    摘要： The invention provides improved suppression of co-channel interference (CCI) in a wireless cellular communications system where at least two base stations use the same transmit frequency. The method according to the invention uses the difference in synchronization times between the home signal and the CCI signal to suppress the CCI signal. The method uses a modified known method of estimating time of arrival (TOA) to estimate sync positions for the CCI signal. This enables the use of interference cancelling methods in communications systems using un-synchronized base stations. Receiver performance is improved, which in turn improves data throughput and received speech quality, since interfering signals from base stations using the same frequency can be suppressed.

    摘要： The radio base station system shifts and directly allocates the transmission timing for a new user from a normal transmission timing to an optimal transmission timing position within the slot to which a mobile terminal device of the new user is about to connect. Thus, it becomes unnecessary to narrow in advance the transmission timings for users already connected to the relevant slot.

    摘要： A slot of a low multiplicity is processed to narrow transmission timing intervals for already-connected users and thereby to make preparation for a new user, and a slot of a high multiplicity is processed to keep the maximum transmission timing intervals for the already-connected users so that the preparation for the new user is not performed. As a result, it is possible to provide the slot prepared for the new user while maximizing the transmission timing intervals. Further, the transmission timing intervals for the already-connected users are kept as large as possible during the traffic channel for preventing the deterioration of characteristics, and the shifting of the transmission timing is performed for the new user during the control channel so that the optimum transmission timing intervals can be achieved when the traffic channel is established. A DSP (14) executes the processing.
