Abstract

A method and equipment for regulating a communication parameter are provided. The method includes that: a first equipment establishes a communication with a second equipment according to a preset configuration of a Cyclic Prefix (CP) length; the first equipment regulates the configuration of the CP length according to a network state and/or service state in a communication process; and the first equipment sends CP length regulation indication information to the second equipment, the CP length regulation indication information indicating a result of regulation performed by the first equipment on the configuration of the CP length; wherein the first equipment is network equipment, and the second equipment is terminal equipment.

First claim

The invention claimed is:

1. A method for regulating a communication parameter, comprising:
establishing, by first equipment, a communication with second equipment according to a preset configuration of the communication parameter, the communication parameter comprising multiple access manner for communication;
regulating, by the first equipment, the multiple access manner according to a network state and/or service state in a communication process; and

sending, by the first equipment, communication parameter regulation indication information to the second equipment, the communication parameter regulation indication information indicating a result of regulation performed by the first equipment on the multiple access manner;
wherein the first equipment is network equipment, and the second equipment is terminal equipment;
wherein sending the communication parameter regulation indication information to the second equipment comprises:
sending the communication parameter regulation indication information to the second equipment through a physical layer control channel;
wherein the communication parameter further comprises a basic physical layer parameter corresponding to the multiple access manner, and the basic physical layer parameter comprises a Cyclic Prefix (CP) length.

2. The method as claimed in claim 1 , wherein the multiple access manner comprises at least one of:
Orthogonal Frequency Division Multiplexing Access (OFDMA), or
Single-carrier Frequency-Division Multiple Access (SC-FDMA).

3. The method as claimed in claim 1 , wherein the network state comprises a channel environment between the first equipment and the second equipment.

4. The method as claimed in claim 1 , further comprising:
sending, by the first equipment, a random access response message to the second equipment, wherein the preset configuration of the multiple access manner is contained in the random access response message.

5. A method for regulating a communication parameter, comprising:
establishing, by second equipment, a communication with first equipment according to a preset configuration of the communication parameter, the communication parameter comprising multiple access manner for communication; and
receiving, by the second equipment, communication parameter regulation indication information sent by the first equipment, the communication parameter regulation indication information indicating a result of regulation performed by the first equipment on the multiple access manner according to a network state and/or service state in a communication process;
wherein the first equipment is network equipment, and the second equipment is terminal equipment;
wherein receiving the communication parameter regulation indication information sent by the first equipment comprises:
receiving the communication parameter regulation indication information sent by the first equipment through a physical control channel;
wherein the communication parameter further comprises a basic physical layer parameter corresponding to the multiple access manner, and the basic physical layer parameter comprises a Cyclic Prefix (CP) length.

6. The method as claimed in claim 5 , wherein the multiple access manner comprises at least one of:
Orthogonal Frequency Division Multiplexing Access (OFDMA), or
Single-carrier Frequency-Division Multiple Access (SC-FDMA).

7. The method as claimed in claim 5 , wherein the network state comprises a channel environment between the first equipment and the second equipment.

8. The method as claimed in claim 5 , further comprising:
receiving, by the second equipment, a random access response message sent by the first equipment, wherein the preset configuration of the multiple access manner is contained in the random access response message.

9. An equipment for regulating a communication parameter, comprising:
a processor; and
a memory configured to store instructions executable for the processor, wherein the processor is configured to:
establish a communication with second equipment according to a preset configuration of the communication parameter, the communication parameter comprising a multiple access manner for communication, regulate the multiple access manner according to a network state and/or service state in a communication process; and
send communication parameter regulation indication information to the second equipment, the communication parameter regulation indication information indicating a result of regulation performed by the equipment on the multiple access manner;
wherein the equipment is network equipment, and the second equipment is terminal equipment;
wherein the processor is specifically configured to:

send the communication parameter regulation indication information to the second equipment through a physical control channel;
wherein the communication parameter further comprises a basic physical layer parameter corresponding to the multiple access manner, and the basic physical layer parameter comprises a Cyclic Prefix (CP) length.

10. The equipment as claimed in claim 9 , wherein the multiple access manner comprises at least one of:
Orthogonal Frequency Division Multiplexing Access (OFDMA), or
Single-carrier Frequency-Division Multiple Access (SC-FDMA).

11. The equipment as claimed in claim 9 , wherein the network state comprises a channel environment between the equipment and the second equipment.

12. The equipment as claimed in claim 9 , wherein the processor is specifically configured to:
send a random access response message to the second equipment, wherein the preset configuration of the multiple access manner is contained in the random access response message.

13. An equipment for regulating a communication parameter, comprising:
a processor; and
a memory configured to store instructions executable for the processor, wherein the processor is configured to:
establish a communication with first equipment according to a preset configurations of the communication parameter, the communication parameter comprising a multiple access manner for communication; and
receive communication parameter regulation indication information sent by the first equipment, the communication parameter regulation indication information indicating a result of regulation performed by the processing module on the multiple access manner according to a network state and/or service state in a communication process;
wherein the first equipment is network equipment, and the equipment is terminal equipment;
wherein the processor is specifically configured to: receive the communication parameter regulation indication information sent by the first equipment through a physical control channel;
wherein the communication parameter further comprises a basic physical layer parameter corresponding to the multiple access manner, and the basic physical layer parameter comprises a Cyclic Prefix (CP) length.

14. The equipment as claimed in claim 13 , wherein the multiple access manner comprises at least one of:
Orthogonal Frequency Division Multiplexing Access (OFDMA), or
Single-carrier Frequency-Division Multiple Access (SC-FDMA).

15. The equipment as claimed in claim 13 , wherein the network state comprises a channel environment between the first equipment and the equipment.

16. The equipment as claimed in claim 13 , wherein the processor is specifically configured to:
receive a random access response message sent by the first equipment, wherein the preset configuration of the multiple access manner is contained in the random access response message.
