(4) Synchronization signal block (SSB): The SSB occupies four consecutive orthogonal frequency division multiplexing symbols, and the SSB may include an NR-PSS, an NR-SSS, and an NR-PBCH.
(5) Control resource set (CORESET): A function of the CORESET is similar to a function of a downlink control area in LTE. The CORESET includes a plurality of physical resource blocks in frequency domain and includes a plurality of orthogonal frequency division multiplexing symbols in time domain.
(6) Time unit: The time unit is essentially a time domain resource, and may be referred to as, but is not limited to, a slot, a subframe, a symbol, a frame, a transmission time interval (TTI), or the like.
In addition, it should be understood that in the descriptions of this application, words “first”, “second” and the like are merely used for distinction description, and cannot be understood as an indication or implication of relative importance or an indication or implication of an order.
In this embodiment of this application, a process in which the terminal device 102 accesses the network device 101 may be as follows: First, the terminal device 102 searches a cell, to obtain system information of the cell, and the terminal device 102 may achieve downlink synchronization with the cell by using the system information of the cell. Then, the terminal device 102 may establish a connection to the cell and achieve uplink synchronization by using a random access procedure (RAP).
