Abstract
Embodiments of the present invention provide an information transmission method and apparatus. The method comprises: a first device obtains first indication information sent by a second device, the first indication information being used for indicating first system information required by the second device; and the first device sends the first system information according to the first indication information. By means of the embodiments of the present application, the sending efficiency can be improved, signaling overheads can be reduced, and a resource waste can be avoided.
Claims17
A method for information transmission, comprising:
- acquiring, by a first device, first indication information transmitted by a second device, wherein the first indication information is used to request first system information required by the second device, and the first indication information is first physical layer indication information, wherein the acquiring, by the first device, the first indication information transmitted by the second device comprises:
- acquiring, by the first device, the first physical layer indication information transmitted by the second device via a physical layer resource block corresponding to the first system information requested by the first physical layer indication information, wherein physical layer resource blocks via which the first physical layer indication information is acquired have one-to-one correspondences with pieces of first system information;
- and
- transmitting, by the first device, the first system information according to the first indication information.
A method for information transmission, comprising:
- determining, by a first device, that system information needs to be transmitted, when a sequence is detected on radio resources for transmitting first indication information by the second device, wherein the first indication information is used to request for the system information, and the first indication information is first physical layer indication information, and wherein the first physical layer indication information transmitted by the second device is acquired via a physical layer resource block corresponding to the system information requested by the first physical layer indication information, wherein physical layer resource blocks via which the first physical layer indication information is acquired have one-to-one correspondences with pieces of system information;
- and
- transmitting, by the first device, the system information.
A method for information transmission, comprising:
- transmitting, by a second device, first indication information to a first device, wherein the first indication information is used to request first system information required by the second device, and the first indication information is first physical layer indication information, wherein transmitting, by the second device, the first indication information to the first device comprises:
- transmitting, by the second device, the first physical layer indication information through a physical layer resource block corresponding to the first system information requested by the first physical layer indication information, wherein physical layer resource blocks via which the first physical layer indication information is acquired have one-to-one correspondences with pieces of first system information;
- and
- acquiring, by the second device, the first system information transmitted by the first device.
