    Abstract: A data transmission method, including: receiving, by a terminal device on a first time domain resource, at least one piece of downlink data sent by a network device; and sending receiving status information to the network device on a second time domain resource. A transmission time interval of any piece of downlink data is less than a transmission time interval of the receiving status information, and the transmission time interval of the any piece of downlink data is less than 1 ms. According to the data transmission method, a transmission time interval of downlink data and a time interval between a sending time of the receiving status information and a receiving time of the at least one piece of downlink data are shortened, thereby reducing a latency.

    Abstract: Embodiments of the present invention provide methods for transmitting and receiving a control channel, a base station, and a user equipment, which relate to the communication field, and can solve a transmission problem of available changing transmission resources caused by introduction of an E-PDCCH. A method includes determining, by a terminal device, a resource set and resource elements (REs) of predetermined overheads in the resource set. The REs of the predetermined overheads include an RE of at least one of a paging channel and a synchronization channel, with at least one of following REs: an RE of a channel state information-reference signal (CSI-RS), an RE of a cell-specific reference signal (CRS), an RE of a demodulation reference signal (DMRS), or a muted RE. The terminal device receives from a base station, a control channel on an RE subset comprised in the resource set, wherein the RE subset comprises a part of the REs in the resource set and do not contain the REs of the predetermined overheads.

    Abstract: Embodiments disclose a data transmission method and a related apparatus, to enable a network device to schedule uplink transmission and a time resource on which the uplink transmission is located. One method includes transmitting, by a terminal device, a scheduling request, where the scheduling request includes information about at least one first transport block. The method also includes receiving, by the terminal device, scheduling information on a first time resource, and determining, by the terminal device, a target time resource, where the target time resource includes a second time resource or a third time resource, and a time interval between the second time resource and the first time resource is greater than a time interval between the third time resource and the first time resource. The method further includes transmitting, by the terminal device, a second transport block on the target time resource based on the scheduling information.

    Abstract: The present disclosure relates to the field of wireless communications technologies, and discloses a random access method and apparatus, a base station, and UE, to resolve a problem of long time required by random access. According to embodiments of the present disclosure, a base station receives a random access preamble sent by user equipment UE, where the random access preamble is used to indicate that the UE has a first transmission capability; the base station sends DCI to the UE by using a PDCCH; the base station sends an RAR for the random access preamble to the UE by using a DL-SCH transport block indicated by the DCI; and the base station receives a UL-SCH transport block sent by the UE according to uplink scheduling information carried by the RAR. Solutions provided by the embodiments of the present disclosure are applicable to a process in which UE accesses a network.

    Abstract: Embodiments of the present disclosure provide an uplink information transmission method and apparatus. The method includes: user equipment determining uplink data information and uplink control information, where a length of a time domain resource corresponding to the uplink data information is not equal to a length of a time domain resource corresponding to the uplink control information; and when the time domain resource corresponding to the uplink data information overlaps with the time domain resource corresponding to the uplink control information, transmitting first information on an overlapping time domain resource, where the first information includes at least one of second information and third information. According to the present disclosure, a problem of transmitting uplink control information or uplink data information that correspond to time domain resources of different lengths and a conflict occurs between their corresponding time domain resources can be resolved.
