    Abstract: Embodiments provide methods and devices for data transmission and assignment of uplink control channel resources in an uplink FDD carrier, for enabling a recipient to provide HARQ feedback for data transmitted in the downlink using carrier aggregation of a downlink FDD carrier and at least one TDD carrier. A method includes associating each downlink subframe in the downlink FDD carrier with an uplink control channel subframe in the uplink FDD carrier, associating each downlink subframe and special subframe in the TDD carrier with an uplink control channel subframe in the uplink FDD carrier, assigning uplink control channel resources in the uplink FDD carrier to the recipient, according to the made associations, and transmitting data on said downlink FDD carrier and/or TDD carrier, to be received by the recipient.

    Abstract: The present application discloses a method for transmitting uplink control information, a user equipment, and a base station. The method includes: receiving a physical downlink control channel sent by a base station, where the physical downlink control channel includes indication information, where the indication information is used to indicate a physical uplink control channel resource used to transmit uplink control information; obtaining, according to the indication information and whether the uplink control information includes periodic channel state information, a physical uplink control channel resource used to transmit the uplink control information from a semi-statically configured first resource group and/or second resource group; and sending the uplink control information to the base station over a physical uplink control channel corresponding to the physical uplink control channel resource.

    Abstract: A user equipment includes a processor and a non-transitory computer-readable storage medium storing a program. The program includes instructions to determine a frame structure of a serving cell. Each frame based on the frame structure comprises 2k subframes having at least: (N−1) downlink subframes, (N−1) uplink subframes, and one special subframe which is a first or second special subframe. N and k are each positive integers greater than or equal to i. The program has instructions to send and receive information in frames based on the frame structure. Each frame has N downlink subframes, N uplink subframes, and (2k−2N) special subframes, where N is less than k, or N downlink subframes, (N−1) uplink subframes, and one second special subframe, where N is equal to k, or (N−1) downlink subframes, N uplink subframes, and one first special subframe, where N is equal to k.

    Abstract: Embodiments of the present disclosure provide a data transmission method, a base station and user equipment. The method includes: sending, by a first base station, first information to a second base station, or receiving, by the first base station, the first information sent by the second base station, wherein the first information is used for indicating that the second base station is to serve user equipment; sending, by the first base station, second information to the user equipment, wherein the second information is used for instructing the user equipment to operate on a carrier corresponding to the second base station, for enabling the user equipment to operate on the carrier corresponding to the second base station. By adopting the embodiments of the present disclosure, the probability of wrong scheduling of high-capacity user equipment is reduced, and the performance loss caused by wrong scheduling is avoided.

    Abstract: A method for transmitting and receiving Uplink Control Information (UCI), a terminal, and a base station are provided. The transmitting method includes: calculating the number (Q′) of modulation symbols occupied by the UCI to be transmitted; dividing the information bit sequence of the UCI to be transmitted into two parts; using Reed Muller (RM) (32, 0) codes to encode each part of information bit sequence of the UCI to be transmitted to obtain a 32-bit coded bit sequence respectively, and performing rate matching so that the rate of the first 32-bit coded bit sequence is ┌Q′/2┐×Qm bits and that the rate of the second 32-bit coded bit sequence is (Q′−┌Q′/2┐)×Qm bits; and mapping the two parts of coded bit sequences that have undergone rate matching onto a Public Uplink Shared Channel (PUSCH), and transmitting the coded bit sequences to a base station.

    Abstract translation: 提供了一种用于发送和接收上行链路控制信息(UCI),终端和基站的方法。 发送方法包括:计算被发送的UCI占用的调制符号的数量(Q'); 将要发送的UCI的信息比特序列划分为两部分; 使用Reed Muller(RM)(32,0)代码对要发送的UCI的信息比特序列的每个部分进行编码,以分别获得32位编码比特序列,并执行速率匹配,使得第一32- 位编码位序列为┌Q'/2┐×Qm位,第二个32位编码位序列的速率为(Q'-┌Q'/2┐)×Qm位; 以及将经历了速率匹配的编码比特序列的两部分映射到公共上行链路共享信道(PUSCH)上,并将编码的比特序列发送到基站。
