Abstract: A data sending method, a related device, and a system are described. The method includes sending, by a network device, resource location information of a first reference signal and a physical channel to a terminal, where a first time-frequency resource on which the first reference signal is mapped overlaps a second time-frequency resource corresponding to the physical channel. An overlapping resource is not used to transmit the physical channel, and a third time-frequency resource in the second time-frequency resource other than the overlapping resource is used to transmit the physical channel. Alternatively, an overlapping resource is used to send a second reference signal; or an overlapping region is used to send a second reference signal, where the terminal skips sending the first reference signal, and the second reference signal is orthogonal to the first reference signal.

Abstract: A candidate control channel resource determining method and apparatus are provided. Under the method, a first and a second aggregation level can be determined by a terminal. The aggregation level is a quantity of control channel resource elements in a candidate control channel. The first aggregation level is less than the second aggregation level. Control channel resource elements in a candidate control channel set corresponding to the second aggregation level form a first quantity of candidate control channel sets corresponding to the first aggregation level. One of the first quantity of candidate control channel sets corresponding to the first aggregation level can be determined as a target set based on an identifier of the terminal. A control channel resource element occupied by each candidate control channel in the target set can be determined. A candidate control channel in the target set can be detected for a received signal.

Abstract: This application provides an uplink power control method and apparatus. A network side device sends a plurality of pieces of configuration information of an RACH to UE, and indicates, by using a scheduling message of the RACH, identifier information of the configuration information of the RACH used by the UE. The UE calculates a transmit power of the RACH based on the configuration information that is of the RACH and that is corresponding to the identifier information, and sends a random access preamble to the network side device based on the transmit power of the RACH.

Abstract: Embodiments of the present disclosure provide, among other implemetations, sequence determining methods. One example method provides a sequence group, and one sequence group number is corresponding to at least two sequences, where one sequence is used for mapping to consecutive subcarriers, and at least one other sequence is used for mapping to equally-spaced subcarriers. In some embodiments of the present disclosure, as high as possible cross-correlation between a sending signal obtained after equally-spaced mapping is performed on a sequence in a sequence group can be determined, and a sending signal obtained after continuous mapping is performed on another sequence in the group.

Abstract: Embodiments of the present disclosure provide an information feedback method. A user equipment (UE) detects downlink transmission data in a received subframe. The UE sends a response message for the downlink transmission data to an access network device, where the response message is sent by the UE on an uplink symbol in a Kth subframe after the received subframe, K is the same for any subframe arrangement in a TDD system, and K is a positive integer. The embodiments of the present disclosure are applied to the TDD system. An ACK or NACK feedback time is reduced, thereby greatly reducing a HARQ delay and meeting a transmission requirement for an ultralow delay.
