Abstract: A communication method includes detecting, by a terminal device, downlink control information (DCI) on at least one of a first physical downlink control channel (PDCCH) candidate or a second PDCCH candidate. The communication method also includes, in response to determining the at least one of the first PDCCH candidate or the second PDCCH candidate is associated with another PDCCH candidate, determining, by the terminal device, a reference PDCCH candidate based on the first PDCCH candidate, the second PDCCH candidate, and the another PDCCH candidate. The reference PDCCH candidate is used to determine at least one of time-frequency-space domain transmission resource information indicated by the DCI, uplink transmit power information indicated by the DCI, or uplink feedback information corresponding to the DCI.

Abstract: A method including: When downlink control information includes a first field, the first field includes (N+2) bits. A quantity L of TBs is determined based on the first field. When L is greater than 1, the L TBs can include both a newly transmitted TB and a retransmitted TB. In j consecutive bits in the first field, a bit state of only one bit is 1, bit states of j−1 bits are all 0, and j=N+1−L. k=0, a bit state of a bj bit in the first field is 1, and L consecutive bits in the first field, carry NDI of the L TBs; or k=L+1, a bit state of a bL bit in the first field is 1, and L consecutive bits in the first field, carry NDI information of the L TBs.

Abstract: This disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for obtaining an uplink-downlink carrier frequency spacing. The method for obtaining an uplink-downlink carrier frequency spacing may include initiating, by user equipment (UE), a request in a first cell to access an NB-IoT, and receiving an indication message sent by a base station. The method may also include 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.
