Abstract: A reference signal transmission method is disclosed, the method including: determining at least two first reference signal resources; receiving a first channel based on the at least two first reference signal resources when a scheduling offset is less than or equal to a preset threshold and/or there is no spatial relation parameter information indication field in downlink control information DCI; and demodulating the first channel. When data on at least two reference signal resources needs to be received within a period of time, the method can increase a probability that a terminal device successfully receives the data.

Abstract: This application provides channel information obtaining methods and communications apparatuses, to reduce pilot overheads and a delay of obtaining channel information. In an example method, a terminal device receives one or more first reference signals on a dth port of the terminal device, where the first reference signal is a reference signal from a first network device. The terminal device obtains a first channel vector h1,d based on the received first reference signal, where h1,d a channel vector of a channel between the dth port of the terminal device and the first network device. The terminal device receives N second reference signals on the dth port of the terminal device. The terminal device obtains a second channel vector h2,d based on the received second reference signal.

Abstract: An uplink power control method comprises: receiving configuration information of a channel state information reference signal (CSI-RS) from a base station, wherein the configuration information of the CSI-RS comprises reference signal port information and reference signal power information; and measuring a path loss for uplink power control based on the configuration information of the CSI-RS. Using the CSI-RS to measure the path loss differs from using a common CRS in that the CSI-RS may be aimed at a specific base station. Therefore, path loss measurement may be performed with respect to a target base station of uplink transmission, enabling the path loss compensation to match the actual path loss, thus improving the performance of uplink power control.

Abstract: Embodiments of the present invention disclose a signaling receiving method and a related device. The method includes: determining, by a terminal based on resource unit allocation signaling, locations of S resource units in a system bandwidth that are scheduled to the terminal; grouping, by the terminal, the S resource units into K resource groups, where a quantity of resource units that separate any resource unit in a first resource group from any resource unit in a second resource group in the system bandwidth is not less than a threshold M; and precoding, by the terminal by using N precoding matrices, data sent in N resource unit sets, where resource units included in each of the N resource unit sets are determined based on the K resource groups, and S, K, and M are all positive integers.

Abstract: Embodiments of the present invention disclose methods and apparatuses for receiving and sending a control channel, and are applicable to the field of communications technologies. In the embodiments of the present invention, a base station carries scheduling information of a user equipment of an R11 system in both the PDCCH region and the E-PDCCH region of a downlink subframe. In this way, the user equipment needs to detect the control channel within the PDCCH region and the E-PDCCH region, so that resources of the two regions are available to the user equipment of the R11 system. Moreover, the user equipment detects only the control channel of the first type in the PDCCH region, and detects control channels of the other type in the E-PDCCH region. The method in the embodiments of the present invention does not increase the number of control channel detections.
