Information transmission method and apparatus
Embodiments of the present disclosure provide an information transmission method and an apparatus, where the information transmission method includes: determining, by a base station, a first transmission resource; sending, by the base station, first information using the first transmission resource, where the first information includes at least one of system information or control information for scheduling system information; determining, by the base station, at least one second transmission resource; and sending, by the base station, second information to UE by using the second transmission resource, where the second information includes at least one of: a paging message, a random access response message, a contention resolution message, control information for scheduling a paging message, control information for scheduling a random access response message, or control information for scheduling a contention resolution message.
1. A base station, comprising:
a transmitter configured to:
send response feedback information to a user equipment (UE); and
send a media access control signaling to the UE, the media access control signaling comprising transmission resource information, wherein the transmission resource information and a transmission resource for the response feedback information indicate a frequency transmission resource for control information for scheduling a contention resolution message; and
a processor coupled to the transmitter and configured to determine the frequency transmission resource for the control information for scheduling the contention resolution message,
wherein the transmitter is further configured to send, to the UE, the control information for scheduling the contention resolution message through the frequency transmission resource.
2. The base station according to claim 1 , wherein the transmitter is configured to send the response feedback information through the frequency transmission resource.
3. The base station according to claim 1 , wherein the response feedback information comprises a random access response.
4. An apparatus, comprising:
a receiver configured to:
receive response feedback information from a base station; and
receive a media access control signaling from the base station, the media access control signaling comprising transmission resource information;
a processor coupled to the receiver and configured to determine, according to a transmission resource of the response feedback information and the transmission resource information, a frequency transmission resource for control information for scheduling a contention resolution message,
wherein the receiver, further configured to receive, from the base station through the frequency transmission resource, the control information for scheduling the contention resolution message.
5. The apparatus according to claim 4 ,
wherein the receiver is further configured to receive the response feedback information through the frequency transmission resource.
6. The apparatus according to claim 4 , wherein the response feedback information comprises a random access response.
7. A method for transmitting control information, the method comprising:
sending response feedback information to a user equipment (UE);
sending a media access control signaling to the UE, the media access control signaling comprising transmission resource information, wherein the transmission resource information and a transmission resource for the response feedback information indicate a frequency transmission resource for control information for scheduling a contention resolution message;
determining the frequency transmission resource for the control information for scheduling the contention resolution message; and
sending, to the UE, the control information for scheduling the contention resolution message through the frequency transmission resource.
8. The method according to claim 7 , further comprising:
sending the response feedback information through the frequency transmission resource.
9. The method according to claim 7 , wherein the response feedback information comprises a random access response.
10. A method for receiving control information, the method comprising:
receiving response feedback information from a base station;
receiving a media access control signaling from the base station, the media access control signaling comprising transmission resource information;
determining, according to a transmission resource of the response feedback information and the transmission resource information, a frequency transmission resource for control information for scheduling a contention resolution message; and
receiving, from the base station, the control information for scheduling the contention resolution message through the frequency transmission resource.
11. The method according to claim 10 , further comprising:
receiving the response feedback information from the base station through the frequency transmission resource.
12. The method according to claim 10 , wherein the response feedback information comprises a random access response.
