20100014505 | METHOD AND DEVICE FOR SERVICE TIME DIVISION MULTIPLEXING - A method and device for service time division multiplexing as well as a method and a device for transmitting service are disclosed. The method for service time division multiplexing includes: selecting a part or all of radio frames in one time unit as specific radio frames; and selecting a part or all of subframes in the specific radio frames as specific subframes for sending a specific service. The specific service is a multimedia broadcast multicast service, or a unicast service, or one or more than one kind of service transmitted in broadcast or multicast mode. | 01-21-2010 |
20100111024 | METHOD AND APPARATUS FOR FEEDING BACK AND RECEIVING ACKNOWLEDGEMENT INFORMATION OF SEMI-PERSISTENT SCHEDULING DATA PACKETS - The present invention relates to radio communications, and discloses a method and apparatus for feeding back and receiving acknowledgment (ACK) information of semi-persistent scheduling (SPS) data packets. The method for feeding back ACK information of SPS data packets includes: receiving an uplink downlink assignment index (UL DAI) from a base station (BS), where the value of the UL DAI indicates the number of downlink data packets (N); mapping ACKs/NAKs of k SPS data packets of the downlink data packets to positions from the (N−k+1)th ACK/NAK to the N | 05-06-2010 |

20130100873 | Data Transmission Method, Base Station and Terminal - The present invention discloses a data transmission method, base station and terminal. The method comprises: transmitting, in every subframe used for transmitting multimedia broadcast multicast service (MBMS), n transport blocks (TBs) to terminals, and transmitting to the terminals the correspondence between the MBMS corresponding to each TB in the subframe and the TB serial number of each TB in the subframe; wherein n is an integer greater than one, a period of time occupies in every subframe by the TBs corresponding to same MBMS is same, and each TB in the subframe corresponds to a unique TB serial number. The present invention can transmit two or more TBs to terminals in every subframe, and the TBs transmitted in the subframe can correspond to different MBMSs, thereby realizing the transmission of TBs corresponding to a plurality of MBMSs in a subframe and improving the spectrum effectiveness of the data transmission. | 04-25-2013 |
20140029486 | METHOD, BASE STATION AND USER EQUIPMENT FOR SUBFRAME CONFIGURATION IN TIME DIVISION DUPLEX SYSTEM - Disclosed are a method, a base station and a user equipment for subframe configuration in a time division duplex system. The method comprises: a base station determining a subframe number of a flexible subframe in a radio frame; the base station determining a feature of the flexible subframe corresponding to the subframe number, where the feature indicates that the flexible subframe is an uplink subframe or a downlink subframe; and the base station sending to a user equipment a first signaling via a downlink control channel, where the first signaling includes the feature of the flexible subframe corresponding to the subframe number. | 01-30-2014 |
20150063280 | METHOD AND DEVICE FOR DATA TRANSMISSION - The present invention provides a method and a device for data transmission.
