Abstract: The present disclosure discloses example communication methods and an example communication device. One example communication method includes receiving, by a communication device and from a first network device in a first communication system, a first access parameter used to access the first communication system and a second access parameter used to access a second communication system, where a system bandwidth of the first communication system is different from a system bandwidth of the second communication system. The first communication system is switched by the communication device to the second communication system based on the second access parameter when a switching condition of switching from the first communication system to the second communication system is satisfied.

Abstract: Example communication methods and apparatus are described. In one example method, a first cell includes a plurality of terminal devices that can transmit uplink data on a same uplink time-frequency resource. A first terminal device in the plurality of terminal devices determines a reference time domain location based on a preconfigured uplink time-frequency resource, where the reference time domain location is the same as a reference time domain location determined by another terminal device in the plurality of terminal devices. The first terminal device determines a time domain location that is (first duration×N H+second duration×(N−1)) away from the reference time domain location as a start time domain location of X gaps. The first terminal device further determines a time domain location that is (first duration×(M−1)+second duration x (M−1)) away from the reference time domain location as a start time domain location of Y first durations, where Y=X or Y=X+1. Uplink data is sent by the first terminal device to a network device on a first time-frequency resource used to transmit uplink data.

Abstract: Example communication methods and apparatus are described. One example method includes determining a random access preamble by a terminal device, The random access preamble includes six symbol groups. The terminal device determines a frequency location of the random access preamble based on random access configuration information and a preset rule. A frequency hopping interval between a first symbol group and a second symbol group and a frequency hopping interval between a fifth symbol group and a sixth symbol group are equal and are first intervals. A frequency hopping interval between the second symbol group and a third symbol group and a frequency hopping interval between a fourth symbol group and the fifth symbol group are equal and are second intervals. A frequency hopping interval between the third symbol group and the fourth symbol group is a third interval. The random access preamble is sent based on the frequency location.

Abstract: A message transmission method and a device are used to accelerate a random access procedure. The method includes: receiving, by a terminal device, a repetition quantity of an uplink message from a network device, in response to determining that a reference signal receive power (RSRP) range of the terminal device is within an RSRP range corresponding to a signal coverage enhancement level 0, wherein the uplink message comprises a third message of a sequence of messages comprised in a random access attempt; calculating, by the terminal device, transmit power based on a power control parameter for the repetition quantity; and sending, by the terminal device, the uplink message to the network device based on the calculated transmit power.
