Abstract: A resource mapping method and an apparatus are provided relating to the communications field, the solutions capable of flexibly implementing resource mapping of a channel or a signal. In one example implementation, first information is obtained that is used to indicate a cyclic shift start resource block location or a cyclic shift end resource block location for resource mapping of a first channel or a first signal in a resource block cyclic shift manner in a bandwidth used by user equipment. A resource mapping location of the first channel or the first signal in the bandwidth used by the user equipment is determined according to the resource block cyclic shift manner and the first information. The first channel or the first signal is received or sent at the resource mapping location. The resource mapping method and the apparatus are used to map a resource.

Abstract: Embodiments of the present disclosure provide a method for transmitting and receiving a service between a terminal device and a base station. The terminal device receives radio resource configuration information and indication information from the base station. The radio resource configuration information includes frequency band information of N (N≥2) frequency ranges and characteristic information of radio interface technologies corresponding to each of the N frequency ranges. The indication information indicates a frequency range in which a physical layer resource is to be used by the terminal device to transmit and receive the service. Characteristics of the radio interface technologies include at least one of: a cyclic prefix (CP) length, a duration of an orthogonal frequency division multiplexing (OFDM) symbol, or a subcarrier spacing.

Abstract: A method and an apparatus for allocating ACKnowledgement (ACK)/Non-ACKnowledgement (NACK) channel resources and processing confirmation information are disclosed. The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.

Abstract: The present invention provides an information transmission method and an apparatus, so as to resolve a problem of high power consumption of a base station resulted from excessively high information overheads for transmitting an MIB by the base station. The method includes: generating, by a base station, an MIB including first bandwidth indication information and a radio frame configuration field; and sending the MIB using a time-frequency resource in a radio frame. Compared with a conventional MIB including a plurality of configuration parameters such as system bandwidth information, a frame number of a radio frame for transmitting the MIB, and PHICH configuration information, the MIB transmitted by the base station in embodiments of the present invention includes two configuration parameters: the first bandwidth indication information and the radio frame configuration field.
