    摘要: The present invention provides a communication method in a time division duplex system, a base station, and user equipment, so as to effectively reduce an RTT and improve data transmission efficiency. The method includes: determining, by a base station, radio frame configuration information; sending, by the base station, the determined radio frame configuration information to user equipment UE, where the radio frame configuration information is used to instruct the UE to set at least one of N consecutive downlink subframes of one radio frame as a first subframe, and/or the radio frame configuration information is used to instruct the UE to set at least one of M consecutive uplink subframes of one radio frame as a second subframe, where the first subframe is used for uplink service transmission, the second subframe is used for downlink service transmission, and N and M are positive integers not less than 2; and communicating, by the base station, with the UE by using a radio frame configured according to the radio frame configuration information.

    摘要: The present invention discloses a method for inserting a downlink common pilot in a TDD system and more particularly to a method for inserting a downlink common pilot in a TDD system based on OFDMA technology and the method includes two steps. A: data to be transmitted are divided into several segments to be transmitted in several continuous time periods, wherein each time period includes several slots with at least one downlink slot; B: a common pilot is inserted in one downlink slot in the time period. Therefore, the scheduling based on the frequency domain can be achieved by measuring the common pilot channel.

    摘要: A wireless communication method for wireless communication system including a transmitting apparatus and a receiving apparatus, comprising:
    transmitting frequency information for transmitting data to a multicast group and offset information indicating an offset amount of a timing at which the data are to be transmitted with respect to a periodic reference timing;
    transmitting the data to the multicast group;
    receiving the frequency information and the offset information; and
    receiving the data being transmitted to the multicast group using a frequency determined by the frequency information at a transmission timing determined by the offset information;
    wherein the data being transmitted to the multicast group is received at a timing determined by the offset amount indicated by the offset information, which is transmitted prior to transmission of the data each time the data transmission is to be performed.

    摘要: A method and the corresponding devices are disclosed for transmitting control information on a control channel associated with a traffic channel. The traffic channel is determined to be either a full- or half rate channel or a quarter rate channel. As a response to determining the traffic channel to be a full- or half rate channel, a control information block of fixed size is transformed into a first number of control information bursts which are all transmitted. As a response to determining the traffic channel to be a quarter rate channel, a control information block of said fixed size is transformed into a second number of control information bursts, where said second number is smaller than the first number. Said second number of control information bursts are transmitted. It is checked, whether a retransmission is requested concerning said second number of transmitted control information bursts. If a retransmission is requested concerning said second transmitted control information bursts, another number of control information bursts is transmitted describing the contents of the control information block which was transformed into said second number of transmitted control information bursts.

    摘要: A radio communication system (10) for preventing transmission and receiving data from colliding with each other in radio relay communication. The radio communication system (10) includes a plurality of radio base stations (2-1 to 2-n) each having a scheduler (21) for arranging a schedule of assignment of a slot into which data is to be inserted in a radio frame, a terminal (3-1 to 3-n) for performing communication with at least one of the radio base stations (2-1 to 2-n) through a connection (C1 to Ck), and a relay station (1) for performing relay forwarding of the radio frame exchanged through the connection, the relay station (1) including a scheduler control section (11) for giving an instruction of the schedule to the scheduler (21). The scheduler control section (11) gives the instruction to the scheduler (21) so as not to generate duplicate slot assignznent, in which the whole or a part of data is assigned to the same slot in radio frames sent at the same timing.
