Information transmission method, base station, and user equipment for exchanging resource information

A base station, comprising:

• a receiver configured to receive a random access preamble from user equipment (UE);
• a processor communicatively coupled to the receiver and configured to generate first information according to the received random access preamble, wherein the first information comprises information about a random access response to the random access preamble, and wherein the first information comprises:
• indication information of a narrowband resource used for transmission of a control channel;
• or
• resource allocation information used for transmission of second information, wherein the second information comprises information about a response to the first information and the resource allocation information used for transmission of second information indicates the narrowband resource and resource allocation within a narrowband;
• and
• a transmitter communicatively coupled to the processor and configured to send the first information to the UE,
• wherein the narrowband includes six physical resource blocks (PRBs), and wherein 3 bits are used for indicating the resource allocation within narrowband as illustrated in the following table:
• Resource indication lit status
• Resource within
• within the narrowband

A user equipment (UE), comprising:

• a transmitter configured to send a random access preamble to a base station;
• and
• a receiver communicatively coupled to the transmitter and configured to receive first information corresponding to the random access preamble, wherein the first information comprises information about a random access response of the base station to the random access preamble, and wherein the first information further comprises:
• indication information of a narrowband resource used for transmission of a control channel;
• or
• resource allocation information used for transmission of second information by the UE, wherein the second information comprises information about a response by the UE to the first information, and wherein the resource allocation information used for transmission of the second information indicates the narrowband resource and resource allocation within a narrowband,
• wherein the narrowband includes six physical resource blocks (PRBs), and wherein 3 bits are used for indicating the resource allocation within the narrowband, as illustrated in the following table:
• Resource indication bit status
• Resource within
• within the narrowband
