Abstract: An ephemeris information indication method and an apparatus are provided. In the method, a terminal device receives ephemeris information in a time window, where the ephemeris information corresponds to a system information modification period in which the time window is located. The terminal device determines, based on the system information modification period and a start position of the system information modification period, the system information modification period in which the time window is located. The terminal device determines the ephemeris information reference time based on an end position of a 1st time window in the system information modification period in which the time window is located.

Abstract: This application provides a method for transmitting an SS/PBCH block and an apparatus. The method includes: A terminal device receives one SS/PBCH block in an SS/PBCH block burst set, and then obtains indication information based on the one SS/PBCH block. The indication information may be used to indicate candidate indexes of at least one SS/PBCH block in the SS/PBCH block burst set, and a quantity of the candidate indexes is greater than 64. For example, the quantity of candidate indexes may be 128, 160, 180, 196, 240, or the like. A network device may not be limited to 64 candidate indexes. In other words, a quantity of candidate positions used to send the SS/PBCH block is not limited to 64. Therefore, the network device may send a larger quantity of SS/PBCH blocks to the terminal device.

Abstract: A HARQ information transmission method and apparatus, to resolve a problem that HARQ information is not fed back in a timely manner. When a first device cannot successfully send first hybrid automatic repeat request (HARQ) information on a first time-frequency resource, or a second device cannot successfully receive the first HARQ information on the first time-frequency resource, the first device retransmits the first HARQ information on a second time-frequency resource for transmitting second HARQ information corresponding to second data. First data and the second data may be data with different priorities and/or in different groups. In this way, HARQ retransmission flexibility can be improved, and the first HARQ information is transmitted in a timelier manner, so that a data processing latency is reduced as much as possible.

Abstract: An apparatus and method for determining a control information indication are provided, wherein resource usage efficiency of physical broadcast channels can be improved. First information, which is sent by a network device, is received for indicating control information. The first information is used to indicate the number of symbols occupied by a control resource set (CORESET 0) in a time domain and a first offset of the CORESET 0 in a frequency domain. A time-frequency resource position of the CORESET 0 is determined based on the first information and a preset subcarrier spacing. Downlink control information at the time-frequency resource position of the CORESET 0 is received.
