摘要： A transmitter (10) is provided with an MAC-PDU generating section (12), which multiplexes an information element and generates an MAC-PDU; and a first data unit transmitting section (13), which transmits the generated MAC-PDU, in an MAC layer. The information element is of an MAC-SDU received from an RLC layer, an MAC control block or padding. The MAC-PDU generating section (12) adds to an MAC-PDU an MAC header including a C/T for identifying the type of the information element to be multiplexed into the MAC-PDU and an LI for indicating the size of the information element.

摘要： In a disclosed method, a mobile station determines whether handover is intra-base-station based on a received signal; the mobile station sends a handover request indicating the determination result to a base station; the base station determines whether the handover is intra-base-station or inter-base-station based on the handover request; and the base station performs an intra-base-station handover process based on a CQI reception level threshold for intra-base-station handover if the handover is intra-base-station.

摘要： A multi-carrier CDMA radio transmitting method replicates each information symbol and disposes thus-obtained information symbols along a frequency axis, multiplies the thus-obtained information symbols with a spreading code along the frequency axis, spreads the information symbols into components of a plurality of sub-carriers having different frequencies. The transmission rate of the information is changed by controlling the amount of information transmitted simultaneously by controlling the number of the information symbols to be used for spreading for the plurality of sub-carrier components for each user to which the information is to be transmitted.

摘要： There are provided a channel estimation unit for achieving highly accurate channel estimation, a CDMA receiver and a CDMA transceiver with the channel estimation unit. Channel estimates of data symbols are obtained from a pilot symbol sequence which is parallel with a data symbol sequence. First, a plurality of pilot blocks are generated from the pilot symbol sequence. The channel estimates of the data symbols are obtained by calculating a sum of appropriately weighted averages of pilot symbols in the individual pilot blocks. This enables highly accurate channel estimation. More accurate channel estimation can be achieved by carrying out the channel estimation of the data symbols using the pilot symbols belonging to other slots rather than limiting to the pilot symbols in the slot to which the estimated data symbol belongs.
