Abstract: According to embodiments of the present invention, a quantity of available state values of a reference signal configuration is increased by indicating a dual-codeword transmission mode and two single-codeword transmission modes, where the two single-codeword transmission modes are distinguished by using a new data indicator NDI. Therefore, higher-rank (such as 16-layer or 24-layer) MU-MIMO can be supported, increasing system spectral efficiency significantly, and improving MU-MIMO configuration flexibility and resource scheduling effectiveness.

Abstract: Embodiments of the present disclosure describe a control signaling reception method and apparatus. The method includes: receiving to-be-received control signaling using a control channel, wherein the control signaling carried on the control channel indicates operation of at least two terminal devices; and demodulating the to-be-received control signaling; wherein the control channel occupies a part of subcarriers in a system bandwidth in a frequency domain. According to the embodiments of the present disclosure, common control signaling that can indicate operation of multiple terminal devices and user dedicated control signaling that can indicate an operation behavior of only one terminal device are carried on different physical channels for transmission. In this way, different resource mapping manners and different signal processing manners can be used according to different transmission requirements, so as to optimally balance resource overheads and transmission reliability of different types of control signaling, thereby improving transmission resource use efficiency.

Abstract: This application discloses a reference signal sending method, a base station, and user equipment, to relieve a problem of low utilization of time-frequency resources. The method may include receiving, by a base station, a measurement result, sent by user equipment (UE), of a downlink reference signal from a serving cell of the UE, where the base station is a base station to which the serving cell belongs. The method may also include determining, by the base station based on the measurement result, whether a predetermined handover preparation condition is met. When the predetermined handover preparation condition is met, the method may include instructing, by the base station, a neighboring cell to send the downlink reference signal to the UE using a time-frequency resource configured by the base station, where the neighboring cell does not send the downlink reference signal to the UE before the neighboring cell is instructed. Furthermore, the method may include instructing, by the base station, the UE to receive the downlink reference signal using the time-frequency resource configured by the base station.

Abstract: Embodiments can provide a random access method. In this method, a preamble sequence can be sent by user equipment (UE), and a random access response can be received by the UE. The random access response includes information for sending a message 3, and the information for sending the message 3 is used by the user equipment to determine a beam for sending the message 3. The beam for sending the message 3 can then be determined based on the information for sending the message 3. The message 3 can be sent by using the determined beam.

Abstract: Embodiments provide an uplink signal acknowledge method. In the method, an uplink signal sent by a terminal device for tracking the terminal device can be received by a base station or a transmission/reception point (TRP). A downlink tracking acknowledge message can be sent to the terminal device. The downlink tracking acknowledge message can include at least one of the following: information about a status in which the base station or the TRP tracks the terminal device, timing advance information required by the terminal device to send an uplink tracking signal, power adjustment information required by the terminal device to send the uplink signal, and access control information of the terminal device. The base station or the TRP sends the downlink tracking acknowledge message to the terminal device, so that the terminal device learns whether a network has tracked the terminal device.
