摘要： In an error control apparatus on a receiving side using a hybrid ARQ which combines an error correcting encoding method and an automatic repeat request method, a buffer stores hard decision result data or soft output data instead of soft decision information in order to reduce a memory capacity of the buffer, and re-encodes the data stored to be provided to a combiner. Alternatively, the number of bits of the data stored in the buffer is restricted or a memory included in a decoder is used as an HARQ buffer.

摘要： A communication method for a communication system is disclosed. The communication system includes a base station and a plurality of terminal apparatuses which perform random access when communicating with the base station. Each of the plural terminal apparatuses randomly accesses the base station by transmitting an access signal.

摘要： In transmission in which MIMO is applied, there have been problems that the number of variable parameters increases and the number of information bits necessary for control channel increases. When the number of simultaneous multiplex users in one frame increases, there is also a problem of increased control channel information in proportion to the number of users. Error correction coding is performed for the control channel information based on the Adaptive Modulation and Coding scheme, and the above error correction coded control channel information is transmitted after being modulated with a predetermined modulation scheme, and further, according to propagation condition, the coding rate in the above error correction coding is made variable.

摘要： An error rate of a TFCI of a transmission data format, and when an error rate of the TFCI becomes worse, a request to increase only the power of the TFCI is issued zn the transmitter. The error rate of the TFCI is computed from the error detection result of a TrCH. Especially when the data length of the TrCH is relatively short, this method is not applied, but wasteful power consumption increases. When the data length of the TrCH is long, this method is applied to realize error rate control with the wasteful power consumption minimized.

摘要： The present method adds uplink data to a transmission request sent to the base station (2) from the mobile station (1) for obtaining permission for data transmission, or to a channel establishment request sent from the mobile station (1) to the base station (2) for establishing a channel in order to send the transmission request therethrough. This makes it possible to suppress delay caused by negotiation prior to actual uplink data transmission as much as possible, thereby realizing efficient uplink data transmission, that is, improved throughput of uplink communication.
