Invention relates to a method of encoding and transmitting feedback information in a multi-carrier wireless network. A first network node is operable to receive signals from the second network node on two or more reception carriers and transmit data to the second network node on one or more transmission carriers. Each reception carrier is transmitted within an associated a radio band. The method comprises steps of: (i) monitoring a signal on at least two of the reception carriers; (ii) generating feedback information for at least two of the reception carriers based on received signals; (iii) grouping the feedback information for reception carriers being transmitted within the same radio band; and encoding said grouped feedback information for two or more reception carriers being transmitted within the same radio band; and (iv) transmitting the encoded feedback information to the second network node on one or more transmission carriers.

Wireless data transmission method and apparatus

Wireless data transmission method and apparatus

Invention relates to a wireless data transmission apparatus and a wireless data transmission method, used, for example, in the remote control panel of an electronic device operating based on wireless data transmission. The technical result is achieved through a wireless data transmission system which includes a transmitting side, which is equipped with a control microcomputer, for transmitting data, and also includes a receiving side for receiving data; to prevent the receiving side from receiving identical data more than once, automatic successive increment of the index number is performed each time a transmission data frame is transmitted; subsequent processing is performed if it is determined that transmission was performed correctly, or data are transmitted without successive increment of the index number if it is determined that transmission was not performed correctly; the index number is returned to the initial value if the control microcomputer is reset, and empty data are transmitted along with the initial value immediately after reset.

Device and method for access via end-to-end emulation of pseudo wire

Device and method for access via end-to-end emulation of pseudo wire

Invention relates to end-to-end emulation of pseudo wire (PWE3) in telecommunication. Proposed method comprises the steps whereat after receipt of no-Ethernet data transmitted by local user the provider local interface device encapsulates said no-Ethernet data in PWE3 internal layer frame format and L2VPN outer layer frame format. Then, it transmits encapsulated data to provider opposite interface device. After provider opposite interface device receives said transmitted data, provider local interface device executes serial de-encapsulation of data received from data in PWE3 internal layer frame format and L2VPN outer layer frame format. Then, it transmits no-Ethernet data produced by two de-encapsulations to local user.

Method, system, user equipment and base station for transmitting uplink control information

Method, system, user equipment and base station for transmitting uplink control information

Method includes sorting uplink control information (UCI) of each downlink carrier in X downlink carriers according to a preset sorting rule, where X is a positive integer, and the X downlink carriers belong to a downlink component carrier set of user equipment; calculating the number of modulation symbols occupied by UCI according to a first carrier set; calculating the number of bits after channel coding of UCI according to the number of modulation symbols occupied by UCI; performing channel coding for the sorted UCI of the X downlink carriers according to the number of bits after channel coding of UCI, mapping the channel coded UCI of the X downlink carriers to a physical channel, and transmitting the mapped UCI of the X downlink carriers.
