Abstract: An information sending method, an information receiving method, and an apparatus are provided. The information sending method includes: generating a downlink channel quality report volume, where the downlink channel quality report volume is used to indicate a relative relationship between a first number of repetitions and a second number of repetitions, the first number of repetitions is a quantity of retransmissions that need to be performed in a preset downlink control channel format to achieve a preset block error rate, and the second number of repetitions is a number of repetitions corresponding to common search space of a downlink control channel carried on a downlink carrier; and sending an MSG3 to a network device in a random access procedure, where the MSG3 is used to indicate the downlink channel quality report volume.

Abstract: A data transmission method and a communications apparatus are described that reduce complexity and overhead of data reception performed by a base station. The method includes receiving information about a repetition quantity R1 corresponding to Tmax, where Tmax is a maximum transport block size allowed to be used to transmit data. The method further includes determining a cyclic parameter L based on R1, where the cyclic parameter L indicates that content carried in each of a plurality of time units to which a transport block used to transmit the data is mapped is repeated in L consecutive time units, and wherein a size of the transport block actually used to transmit the data is Ts, and Ts is less than a maximum transport block size (Tmax). The method further includes transmitting the data based on the cyclic parameter L.

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.

Abstract: This application provides a system message transmission method, an apparatus, and a system. A first communications device configures a MIB message, and the MIB message may carry various different information used to transmit a SIB1, for example, any one or more of scheduling information, first information, and an operation mode of a carrier, so that a second communications device receives the SIB1 based on the MIB message. The first communications device may flexibly configure information used to transmit the SIB1. In addition, when configuring the MIB message, the first communications device may consider ensuring, through configuration or implicit indication, that resource locations for transmitting SIB1s of different cells in one period are different. This type of interference isolation mechanism can avoid mutual interference between transmission of SIB1s of different cells, so that transmission reliability of the SIB1s can be improved.

Abstract: Embodiments of this application provide a random access method. The method includes: determining, by a terminal device, a second access carrier based on a pre-obtained access carrier information list and information about a first access carrier that is indicated by a base station and that can be used for access, where the access carrier information list includes information about all carriers that support random access; and then performing, by the terminal device, random access on the second access carrier. This reduces a probability of a collision between the terminal device and the another terminal device, and avoids interference on use of the another terminal device.

Abstract: The present disclosure relates to SFN indication methods, terminal devices, and positioning servers and systems. One example method includes obtaining an SFN offset indication parameter of a cell i, sending the SFN offset indication parameter of the cell i to a terminal device, receiving the SFN offset indication parameter of the cell i from the positioning server, obtaining a frame number of a radio frame n of a cell j, and determining a phase rotation parameter of the cell i based on the frame number of the radio frame n of the cell j and the SFN offset indication parameter of the cell i, or obtaining a sequence initialization factor used by a narrowband positioning reference signal (NPRS) on a radio frame m of the cell i, and obtaining the NPRS on the radio frame m of the cell i based on the sequence initialization factor.
