摘要： The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating an uplink-downlink carrier frequency spacing, and a method and an apparatus for obtaining an uplink-downlink carrier frequency spacing, so that a terminal obtains a correct NB-IoT system uplink carrier frequency. The method is: obtaining, by a base station, a determining parameter used to determine an uplink-downlink carrier frequency spacing of a first cell, and generating indication information according to the determining parameter, where the indication message is used to indicate the uplink-downlink carrier frequency spacing of the first cell; and sending, by the base station, the indication information to a terminal device UE that initiates a request in the first cell to access an NB-IoT. The method for obtaining an uplink-downlink carrier frequency spacing is: initiating, by UE, a request in a first cell to access an NB-IoT, and receiving an indication message sent by a base station; and determining, by the UE according to the indication information, an uplink-downlink carrier frequency spacing corresponding to the first cell. Therefore, the base station can notify the UE of the uplink-downlink carrier frequency spacing corresponding to the first cell, so that the terminal obtains a correct uplink carrier frequency.

摘要： A communication method and apparatus are provided. The method includes: A terminal device detects DCI on at least one of a first PDCCH candidate and a second PDCCH candidate. If the first PDCCH candidate and the second PDCCH candidate satisfy a specific condition, and when the at least one of the first PDCCH candidate and the second PDCCH candidate is associated with another PDCCH candidate, the terminal device determines a reference PDCCH candidate based on the first PDCCH candidate, the second PDCCH candidate, and the another PDCCH candidate. In the foregoing method, scheduling information determined by the terminal device can be consistent with scheduling information determined by a network device.

摘要： This application discloses a data transmission method and an apparatus. The method includes: A network device generates downlink control information DCI. The DCI can indicate a first modulation scheme or a second modulation scheme, or can indicate only a second modulation scheme. The DCI includes a modulation and coding scheme MCS field. The DCI indicates the first modulation scheme when the MCS field is in a first state, or the DCI indicates the second modulation scheme and an MCS index of the second modulation scheme when the MCS field is in a second state. The network device sends the DCI. A terminal receives the downlink control information DCI, and receives or sends data based on the DCI. In embodiments of this application, the first modulation scheme, the second modulation scheme, and the MCS index of the second modulation scheme are indicated by using different states in the MCS field, to support a new modulation scheme without increasing DCI overheads.

摘要： A gap determining method and a device are provided. The gap determining method includes: A terminal device receives first configuration information and second configuration information from a network device. The terminal device receives scheduling information from the network device, where the scheduling information is used to schedule N transport blocks carried on a first channel. The terminal device determines a downlink gap of the first channel based on the first configuration information. The terminal device determines a first gap between the N transport blocks based on the second configuration information. When the terminal device determines that a preset condition is satisfied, the terminal device determines that a gap part that is included in the first gap and that overlaps with the downlink gap is postponed in time domain and that a gap part obtained through postponing does not overlap with the downlink gap, where the preset condition includes that the first gap includes the gap part that overlaps with the downlink gap; or when the first gap includes a gap part that overlaps with the downlink gap, the terminal device determines that the gap part that is included in the first gap and that overlaps with the downlink gap belongs to the downlink gap.

摘要： This application provides a communication method and apparatus. The method includes: implicitly indicating a quantity of time units for transmitting a data channel and a quantity of times of retransmission of the data channel by using a size of a resource for transmitting a control channel. By using the method in this application, the quantity of the time units for transmitting the data channel and/or the quantity of times of retransmission of the data channel do/does not need to be indicated to a terminal device by using the control channel. Therefore, a payload size of the control channel is effectively reduced, and transmission efficiency and reliability of the control channel are improved.

摘要： A communication method and apparatus are provided, so that a terminal device determines whether DCI obtained through monitoring is repeatedly transmitted on a PDCCH or individually transmitted on a PDCCH. A network device determines first configuration information based on a first condition, and sends the first configuration information to a first terminal device. The first configuration information includes information indicating the first terminal device to monitor a PDCCH candidate based on a span, and includes configuration information of a first PDCCH candidate and a second PDCCH candidate. The first condition is that the first PDCCH candidate and the second PDCCH candidate do not meet at least one of a same time-frequency resource, a same scrambling sequence, a same control resource set, and a same DCI payload size. The first PDCCH candidate and the second PDCCH candidate are located in a same span other than a first span in a slot, the first PDCCH candidate is used for individual transmission, and the second PDCCH candidate is any PDCCH candidate in linked PDCCH candidates for repetition transmission.
