Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.

Abstract: Embodiments of the present disclosure provide example uplink control information transmission methods, terminal devices, base stations, and systems. An example transmission method includes the following steps: First, the terminal device determines an information bit sequence of to-be-transmitted uplink control information. Then, the terminal device determines a first sequence according to the information bit sequence, where the first sequence is a linear-phase complex exponential sequence. Finally, the terminal device sends the to-be-transmitted uplink control information to the base station by using an uplink control channel, where the uplink control channel occupies N symbols, N is a positive integer, a signal carried on a symbol l of the N symbols is directly proportional to a product of the first sequence and a second sequence, and the second sequence is a cyclic shift sequence.

Abstract: A timing method for time division duplex communication, an uplink/downlink data scheduling method, a base station, and user equipment are provided. By determining whether grouping needs to be performed on uplink/downlink short transmission time intervals, it is determined, for different grouping requirements, whether addition of indication information to control signaling is required to indicate to user equipment an uplink short transmission time interval sequence number in an uplink short transmission time interval group for uplink data transmission or feedback to downlink data scheduling. Alternatively, addition of indication information to control signaling is not required, and uplink data transmission or feedback to downlink data scheduling is performed in an uplink short transmission time interval determined according to a default rule.

Abstract: In a control information transmission method according to present disclosure, a user equipment acquires configuration information of an enhanced physical downlink control channel (EPDCCH) set. The user equipment determines, according to the configuration information and from the EPDCCH set, at least one EPDCCH set in which an EPDCCH needs to be monitored. The user equipment monitors an EPDCCH on a resource corresponding to the at least one EPDCCH set, to acquire control information sent by a base station.

Abstract: An information transceiving method, apparatus, and system are described. The information transceiving method includes: determining a subframe length of a serving cell; determining a synchronization signal period of the serving cell based on the subframe length of the serving cell; and sending or receiving information in the serving cell based on the synchronization signal period and the subframe length. In some implementations, the synchronization signal period of the serving cell is determined based on the subframe length of the serving cell.

Abstract: Embodiments provide methods and devices for data transmission and assignment of uplink control channel resources in an uplink FDD carrier, for enabling a terminal device 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 terminal device according to the associations, and transmitting data on said downlink FDD carrier and/or TDD carrier, to be received by the terminal device.

Abstract: The present disclosure discloses an uplink retransmitted data sending method, apparatus, and system, and relates to the field of communications technologies. The method includes: receiving data transmitted on a same contention resource by different user equipments (UEs) that are in a same contention resource group; demodulating, based on a demodulation reference signal DMRS sequence carried in the data, the data sent by the UEs; and when demodulation of data sent by at least two UEs fails, scheduling, by using an uplink grant (UL-grant), the UEs whose data fails to be demodulated, to retransmit the data on a designated non-contention resource. This resolves a prior-art technical problem that uplink data retransmission fails, and improves uplink data retransmission efficiency.

Abstract: This application provides a synchronization signal sending method and receiving method, and an apparatus. In the method, a base station determines a frequency domain position of a target frequency resource based on a frequency interval of synchronization channels, wherein the frequency interval of synchronization channels is 2m times a predefined frequency resource of a physical resource block, and m is a preset nonnegative integer. The base station sends a synchronization signal by using the target frequency resource.
