Abstract: This application discloses a physical uplink control channel sending method, a receiving method, and a communication apparatus. The method includes: A terminal device determines a first transmission manner from a plurality of transmission manners including a first non-frequency hopping transmission manner, and sends a PUCCH to a network device in the first transmission manner. The first non-frequency hopping transmission manner is: sending the PUCCH without frequency hopping in a time unit. UCI on the PUCCH includes a first part and a second part, the first part is sent by using an orthogonal sequence whose length is L1, and the second part is sent by using an orthogonal sequence whose length is L2. The UCI is divided into two parts, and is sent without frequency hopping by using orthogonal sequences with a same length or different lengths.

Abstract: This application relates to the field of communication technologies, and discloses a communication method and apparatus. The method includes: A terminal device receives indication information from a first access network device. The indication information is used to indicate to fall back a capability of the terminal device to a first protocol version. The terminal device communicates, based on the indication information, with the first access network device by using first capability information. A protocol version corresponding to the first capability information is lower than or equal to the first protocol version. In this method, because a network device can explicitly indicate to fall back the capability of the terminal device to the first protocol version, the terminal device can specially reduce the capability, so as to quickly resolve a communication problem caused by incompatibility between the terminal device and the access network device.

Abstract: The present invention provides a signal sending apparatus, a signal detection apparatus, a signal sending and detection system, a signal sending method, and a signal detection method. The apparatus determines a time unit that is in each time window and that is used to transmit a synchronization signal, and transmits the synchronization signal in the determined time unit in each time window. Therefore, a synchronization signal is always located in a time unit that has a fixed location in each time window, so that a device at a receive end needs to perform detection only in a fixed time unit in each time window, thereby reducing complexity of designing and detecting the synchronization signal.

Abstract: In a system and method of control channel transmission in the communications field, REs, except those used for transmitting a DMRS, are grouped in each physical resource block pair of L physical resource block pairs. The L physical resource block pairs are determined to be used to transmit a control channel into N eREGs. The number of valid REs are calculated except other overheads in each eREG of the N eREGs. Each of the eCCEs are mapped onto M eREGs according to the number of valid REs included in each eREG of the N eREGs of each physical resource block pair. The eCCE is sent in the REs included in the eREG.

Abstract: In a process by user equipment (UE) to determine a control channel resource, the UE detects a downlink control from a base station. The downlink control channel carries scheduling information of a downlink data channel and comprises multiple control channel logical elements that correspond to the UE and are mapped to one demodulation reference signal (DMRS) antenna port. The UE acquires antenna port information of the DMRS antenna port, an offset, and sequence number information of the control channel logical elements corresponding to the UE, and determines, according to the acquired information, a first control channel resource for sending acknowledgment (ACK)/non-acknowledgment (NACK) information with respect to the downlink data channel corresponding to the downlink control channel.
