Abstract

Embodiments of the present invention disclose a signal transmission method, user equipment, and a base station. The method includes: determining a feature parameter of UE; and according to the feature parameter of the UE and a preset correspondence, determining a coverage enhancement technology used to transmit a first signal, and/or determining a second signal that the UE supports transmitting, and/or determining a function, supported by the UE, of a third signal. The present invention can optimize resource utilization of a system, decrease processing complexity, and reduce power consumption.

Claims

1. A user equipment (UE) comprising:

a memory storing a preset correspondence and a program; and

a processor for executing the program, the program comprising instructions for;

determining a feature parameter of the UE, wherein the feature parameter of the UE comprises at least one of the following;

an enhancement level, an enhancement level index, an index of a coverage enhancement range, and an index of a reference signal received power range; and

determining, according to a preset correspondence between the feature parameter and a supported function of a physical uplink control channel (PUCCH), the supported function corresponding to the feature parameter of the UE, wherein

the preset correspondence between the feature parameter and the supported function of the PUCCH is;

in response to determining that the feature parameter belongs to a first feature parameter set, the UE supports a function in a first function set of the PUCCH, and

in response to determining that the feature parameter belongs to a second feature Parameter set, the UE supports using a function in a second function set of the PUCCH,

wherein the function in the first function set and the function in the second function set are not completely the same.

2. The UE according to claim 1,

wherein functions in a first function set of the PUCCH includes:

a function of reporting channel quality information, a scheduling request function, and a function of feeding back an acknowledgement indicating whether a signal is correctly received; and

wherein functions in a second function set of PUCCH includes;

a scheduling request function, and a function of feeding back an acknowledgement indicating whether a signal is correctly received.

3. The UE according to claim 1, wherein the preset correspondence is a preset function relationship, a preset table relationship, or a preset specification relationship, and the preset correspondence is preconfigured by a base station by using signaling or is preset by a system.

4. A base station comprising:

a processor;

a memory storing a program to be executed in the process, the memory storing a preset correspondence, the program comprising instructions for;

determining a feature parameter of user equipment (UE), wherein the feature parameter of the UE comprises at least one of the following;

an enhancement level, an enhancement level index, an index of a coverage enhancement range, and an index of a reference signal received power range; and

determining, according to the preset correspondence between the feature parameter and a supported function of a physical uplink control channel (PUCCH), the supported function of the PUCCH, which is corresponding to the feature parameter of the UE, wherein the preset correspondence between the feature parameter and a supported function of the PUCCH is;

in response to determining that the feature parameter belongs to a first feature parameter set, the UE supports a function in a first function set of the PUCCH, and

in response to determining that the feature parameter belongs to a second feature Parameter set, the UE supports using a function in a second function set of the PUCCH,

wherein the function in the first function set and the function in the second function set are not completely the same.

5. The base station according to claim 4,

wherein functions in a first function set of the PUCCH includes:

a function of reporting channel quality information, a scheduling request function, and a function of feeding back an acknowledgement indicating whether a signal is correctly received; and

wherein functions in a second function set of PUCCH includes;

a scheduling request function, and a function of feeding back an acknowledgement indicating whether a signal is correctly received.

6. The base station according to claim 4, wherein the preset correspondence is a preset function relationship, a preset table relationship, or a preset specification relationship, and the preset correspondence is preconfigured by the base station by using signaling or is preset by a system.

7. A signal transmission method, comprising:

determining, by user equipment (UE), a feature parameter of the UE, wherein the feature parameter of the UE comprises at least one of the following;

an enhancement level, an enhancement level index, an index of a coverage enhancement range, and an index of a reference signal received power range; and

determining, according to a preset correspondence between the feature parameter and a supported function of a physical uplink control channel (PUCCH), the supported function of the PUCCH corresponding to the feature parameter of the UE, wherein the preset correspondence between the feature parameter and a supported function of the PUCCH is;

in response to determining that the feature parameter belongs to a first feature parameter set, the UE supports a function in a first function set of the PUCCH, and

in response to determining that the feature parameter belongs to a second feature parameter set, the UE supports using a function in a second function set of the PUCCH,

wherein the function in the first function set and the function in the second function set are not completely the same.

8. The method according to claim 7, wherein the preset correspondence is a preset function relationship, a preset table relationship, or a preset specification relationship, and the preset correspondence is preconfigured by a base station by using signaling or is preset by a system.

9. The method according to claim 7, wherein functions in a first function set of the PUCCH includes:

a function of reporting channel quality information, a scheduling request function, and a function of feeding back an acknowledgement indicating whether a signal is correctly received; and

wherein functions in a second function set of PUCCH includes;
