摘要： A communication terminal apparatus capable of suppressing communication delay independently of the packet size, efficiently performing communication, and further solving the problem of hidden terminals. In this apparatus, a number-of-STAs holding part (107) counts, based on a received signal inputted from an STA determining part (105), the other STAs in the same cell. A back-off establishing part (108), which stores a table or a back-off value calculation formula in accordance with the number of the STAs in the cell, uses the number of the STAs in the information about the number of registered terminals in the cell to select or calculate the corresponding back-off value, thereby establishing the back-off value. A packet generating part (109) generates a packet including both number-of-terminals information and transport data. A transmission standby part (112) establishes a transmission standby time such that only the back-off value is on transmission-standby. The transmission standby part (112) then causes the packet to be on transmission-standby by the established transmission standby time and be outputted after a lapse of the transmission standby time.

摘要： A base station, a mobile station and a retransmission control method for enabling communication to be more efficiently performed. In a communication system comprising a base station (100) and a mobile station (200), a time period required for the retransmission of a transport packet to complete is determined, and a retransmission control is performed, based on the required time period, to change the order of executing the retransmission of the transport packet and a handover. In this way, when it is estimated that the retransmission will complete soon, the retransmission is caused to complete in a handover source system, thereby avoiding waste of communication resources used in the preceding transmission and retransmission processes. When it is estimated that the retransmission will continue for a while, the communication resources used in the preceding transmission and retransmission processes are wasted, but a more appropriate MCS can be assigned, in a handover destination system, so as to perform a retransmission, thereby enabling communication to be efficiently performed.

摘要： A radio communication method is provided that enables the TFC pointer of a communication terminal apparatus to be made to match the TFC pointer of a radio base station apparatus. A mobile station changes its TFC pointer in line with a determined TFC and also transmits a TFCI at point in time t3. The base station checks the TFCI and updates its own TFC pointer so as to match with the TFC indicated by the TFCI. The base station determines a new TFC pointer, generates an up/down/keep signal by comparing the new TFC pointer with the updated TFC pointer, and transmits this signal at point in time t5. The mobile station updates the TFC pointer it is holding based on the up/down/keep signal received at point in time t6. As a result, the TFC pointers of both stations can be made to match even if the mobile station receives an up/down/keep signal erroneously at point in time t2.

摘要： Disclosed are a wireless communication base station and a total transmission power regulating method that reduce interference to macrocell users near a femtocell and interference to neighboring femtocell users near the femtocell in a balanced manner, while ensuring throughput of the femtocell users. A reception power measuring unit (214) measures the reception power of a CPICH. A cell type discriminating unit (216) judges whether the received signal is a signal from a macro base station or a signal from a femto base station. When a signal from a macro base station is received, a total downlink transmission power setting unit (217) executes a first-stage interference regulation based on the strongest CPICH reception power value and calculates a tentative value for the total downlink transmission power of a femto base station (110). When a signal from a peripheral femto base station is received, the total downlink transmission power setting unit (217) executes a second-stage interference regulation within a fixed power regulation range for the second-stage interference regulation based on the strongest CPICH reception power value, and calculates a final total downlink transmission power value.

摘要： A wireless communication apparatus wherein the throughput is improved. In a wireless communication apparatus (100), a frame generating part (120) adds a header to a data portion to form a transport frame. A control part (190) acquires a variation index in a propagation path and decides the length of the data portion of the transport frame in accordance with the propagation path variation index. In this way, when the propagation path variation index is large, that is, the degree of propagation path variation is high, the data portion can be shortened. Contrarily, when the propagation path variation index is small, that is, the degree of propagation path variation is low, the data portion can be elongated. Thus, when the degree of propagation path variation is high and hence the probability of reception of a retransmission request from a receiving end is high, the data portion can be shortened to prevent a degradation of the throughput that would occur due to a transmission of long data. Contrarily, when the probability of reception of a retransmission request is low, a long data can be transmitted to improve the throughput.
摘要翻译：一种提高吞吐量的无线通信装置。在无线通信装置（100）中，帧生成部（120）向数据部添加报头以形成传送帧。控制部分（190）获取传播路径中的变化索引，并且根据传播路径变化指数来确定传输帧的数据部分的长度。以这种方式，当传播路径变化指数大时，即传播路径变化度高时，可以缩短数据部分。相反，当传播路径变化指数小时，即传播路径变化度低时，数据部分可以被拉长。因此，当传播路径变化度高时，从接收端接收到重发请求的概率高时，可以缩短数据部分，以防止由于长时间传输而发生的吞吐量的劣化数据。相反，当重发请求的接收概率低时，可以发送长数据以提高吞吐量。
