Abstract: A fault determining method, includes: a first terminal device monitors a parameter of a sidelink between the first terminal device and a second terminal device, to determine whether a unicast connection on the sidelink satisfies a first condition; and when the unicast connection satisfies the first condition, the first terminal device determines that the unicast connection is faulty.

Abstract: A random access method and apparatus are provided. The method includes sending, by a first terminal side device, a random access preamble to a network side device, receiving, by the first terminal side device, a random access response (RAR) corresponding to the random access preamble, where the RAR includes P temporary cell radio network temporary identifiers (TC-RNTIs), and P is an integer greater than 1, and sending, by the first terminal side device to the network side device based on the RAR, a first message and a demodulation reference signal used to demodulate the first message, where the demodulation reference signal is generated based on a first TC-RNTI, and the first TC-RNTI is one of the P TC-RNTIs.

Abstract: The application relates to allocating transmission resources in communication networks that provide low latency services. A terminal receives, from a base station time-frequency resource division information, which indicates a division of a time-frequency resource that is allowed to be used by another service. The division of the time-frequency resource includes one or more resource units in time domain and one or more resource units in frequency domain. The terminal further receives from the base station time-frequency resource indication information, which indicates that, in the time-frequency resource that is allowed to be used by the other service, at least one time domain resource unit and at least one frequency domain resource unit are occupied by the other service. The terminal communicates with the base station using the time-frequency resource except the at least one time-domain resource unit and at least one frequency-domain resource unit that are occupied by the other service.

Abstract: A resource allocation method to resolve a problem that a transport block of a typical enhanced voice service (EVS) scenario in an air interface is much smaller than a transport block of a conventional adaptive multi rate (AMR), and use of a resource allocation method in the existing long term evolution (LTE) causes a waste of user spectrum resources such that spectrum utilization in an EVS scenario can be improved. The method includes determining resource allocation information and resource allocation block indication information, where the resource allocation information includes information indicating at least one fractional resource block (FRB) allocated to user equipment, and the resource allocation block indication information indicates that a resource allocation block is the FRB, where a resource occupied by the FRB is less than one RB, and notifying the user equipment of the resource allocation information and the resource allocation block indication information.

Abstract: A downlink transmission method and a corresponding base station and terminal are provided. In some feasible implementations, a base station sends downlink control information to a terminal in a subframe n+k, where the downlink control information includes indication information and a HARQ process identification, the indication information is used to indicate a location of at least one OFDM symbol in data that is sent by the base station to the terminal in a subframe n, the HARQ process identification in the downlink control information is the same as a HARQ process identification in the subframe n, and both n and k are natural numbers; and the base station transmits, in the subframe n+k, at least data that is sent to the terminal and that is on the at least one OFDM symbol that is in the subframe n and that is indicated by the indication information.
