Abstract: A multi-antenna operation mode indication method and an apparatus resolve a problem that increased power consumption and a resource waste are caused because a terminal device still operates in a multi-user multiple-input multiple-output (MU-MIMO) mode by default in a single-port transmission mode. The method includes: a network device sends indication information to a terminal device, to indicate that a multi-antenna operation mode of the terminal device is single-user multiple-input multiple-output (SU-MIMO) or MU-MIMO. The terminal device determines, based on the indication information from the network device, whether a demodulation reference signal (DMRS) port number corresponding to the terminal device and a DMRS port number not corresponding to the terminal device are allocated to another terminal device, to adjust the multi-antenna operation mode.

Abstract: Embodiments of this application provide a random access response method and an apparatus. The method includes: RARs associated with one RO are transmitted based on groups, so that a transport block size of RAR data transmitted each time is reduced, and N bits in DCI format 1_0 of CRC are scrambled by using a RA-RNTI to indicate scheduling information of N RAR groups in a PDSCH. Alternatively, DCI format 1_0 of CRC is scrambled by using identifiers of RAR groups, to correspondingly schedule the RAR groups in the PDSCH. According to this application, a problem of a large transport block caused by a large quantity of RARs being transmitted in a PDSCH can be avoided, so that a modulation order or a bit rate is reduced, and demodulation performance of a terminal device is improved.

Abstract: A random access method and an apparatus. In one example: A terminal device receives a first wake-up signal, and then determines N random access channel occasions based on a correspondence between the first wake-up signal and the N random access channel occasions. The terminal device determines a first random access channel occasion in the N random access channel occasions, and sends a random access preamble on the first random access channel occasion. A network device uses, as a reception beam, a beam used to send the first wake-up signal, to receive the random access preamble sent by the terminal device.

Abstract: An SRS transmission method and apparatus are provided. The method includes: A terminal device determines a first frequency band, and receives SRS configuration information from a network device, where the SRS configuration information is used to indicate an SRS transmission frequency band. The terminal device determines the SRS transmission frequency band based on the SRS configuration information, where the SRS transmission frequency band is included in the first frequency band. The terminal device transmits an SRS to the network device in the SRS transmission frequency band. A bandwidth of the first frequency band is greater than a maximum channel bandwidth supported by the terminal device. According to the foregoing method, the terminal device can transmit an SRS within a larger frequency resource range, or a bandwidth corresponding to a transmission frequency band of the SRS is more suitable for a terminal device with a low bandwidth capability.

Abstract: The present disclosure provides a method and an apparatus for transmitting control data. The method includes: determining, by a terminal device, at least one target cell from at least one unlicensed cell; and transmitting, by the terminal device, control data in the target cell. This can implement transmission of the control data on an unlicensed spectrum resource, so that the control data can be transmitted not merely on a licensed spectrum resource, and communication reliability and user experience can be improved. In addition, this can reduce licensed spectrum resource overheads in a communication process, and increase a capacity of a communications system that has a limited quantity of licensed spectrum resources.

Abstract: The present disclosure relates to example data transmission methods, user equipment, and access network devices in an LAA-LTE system. An example data receiving method includes determining, by user equipment, first information of a first cell. The user equipment determines a first subframe based on the first information, where a downlink data transmission length of the first subframe is less than a first threshold. The user equipment then determines a data transmission characteristic of the cell in the first subframe based on a preset condition, so as to receive, based on the data transmission characteristic, data including the first subframe. In doing so, a data transmission characteristic of a base station or a terminal is standardized, and a reference signal such as a DRS can be correctly identified.

Abstract: Embodiments of the present disclosure provide a data channel sending method. In the method, a base station starts a clear channel assessment (CCA) on a data channel for a to-be-sent data channel. If the CCA on the data channel succeeds, the base station sends the data channel in a first subframe within a time window, where the data channel performs rate matching based on a reference signal (RS). The RS includes a first RS or a second RS. The first RS occupies continuous OFDM symbols in a subframe, and the second RS occupies discontinuous OFDM symbols in a subframe. The time window is a preset time window used to send the first RS, and the first RS is used by a user equipment (UE) to perform cell identification and/or a radio resource management (RRM) measurement on a cell served by the base station.
