Abstract

Embodiments of the present invention disclose a measurement configuration method, an identification and measurement method, a macro base station, and UE. The measurement configuration method provided in the embodiments of the present invention includes: configuring, by a macro base station, a first measurement gap pattern for UE; receiving, by the macro base station, indication information sent by the UE, where the indication information is used to represent that quality of a signal radiated by a small base station and received by the UE is higher than or equal to a preset signal quality threshold; and configuring, by the macro base station, a second measurement gap pattern for the UE, where a measurement gap period in the second measurement gap pattern is less than a measurement gap period in the first measurement gap pattern.

First claim

What is claimed is:

1 . A measurement configuration method, comprising:
configuring, by a macro base station, a first measurement gap pattern for user equipment (UE), wherein the first measurement gap pattern refers to a data format that is set by the macro base station for suspending data transmission with the UE when the UE identifies and measures a small base station; receiving, by the macro base station, indication information sent by the UE, wherein the indication information is used to represent that quality of a signal radiated by the small base station and received by the UE is higher than or equal to a preset signal quality threshold, wherein the quality of the signal radiated by the small base station is obtained through measurement by the UE according to the first measurement gap pattern; and configuring, by the macro base station, a second measurement gap pattern for the UE, wherein a measurement gap period in the second measurement gap pattern is less than a measurement gap period in the first measurement gap pattern.

2 . The method according to claim 1 , wherein before receiving, by the macro base station, indication information sent by the UE, the method further comprises:
sending, by the macro base station to the UE, carrier frequency information used by the small base station, reception time window information of the signal radiated by the small base station, and a physical cell identity list.

3 . The method according to claim 1 , wherein the quality of the signal refers to power or a signal-to-interference-plus-noise ratio of the received signal.

4 . An identification and measurement method, comprising:
receiving, by user equipment (UE) according to a first measurement gap pattern configured by a macro base station, a signal radiated by a small base station, measuring quality of the signal, and identifying and measuring a small cell of the small base station based on the signal; when the UE determines that the quality of the signal is higher than or equal to a preset signal quality threshold, sending, by the UE, indication information to the macro base station, wherein the indication information is used to request the macro base station to configure a second measurement gap pattern for the UE, and a measurement gap period in the second measurement gap pattern is less than a measurement gap period in the first measurement gap pattern; and receiving, by the UE, the second measurement gap pattern configured by the macro base station, receiving, according to the second measurement gap pattern, the signal radiated by the small base station, and identifying and measuring the small cell of the small base station based on the received signal radiated by the small base station.

5 . The method according to claim 4 , wherein before receiving, by UE according to a first measurement gap pattern configured by a macro base station, a signal radiated by a small base station, the method further comprises:
receiving, by the UE, carrier frequency information used by the small base station, reception time window information of the signal radiated by the small base station, and a physical cell identity list that are sent by the macro base station.

6 . The method according to claim 4 , wherein before receiving, by UE according to a first measurement gap pattern configured by a macro base station, a signal radiated by a small base station, the method further comprises:
switching, by the UE, to a signal continuous reception mode.

7 . The method according to claim 4 , wherein before receiving, by UE according to a first measurement gap pattern configured by a macro base station, a signal radiated by a small base station, the method further comprises:
activating, by the UE, an idle radio frequency link, to identify and measure the small cell of the small base station.

8 . The method according to claim 4 , wherein the signal is a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or another pilot signal.

9 . The method according to claim 4 , wherein the quality of the signal refers to power or a signal-to-interference-plus-noise ratio of the signal.

10 . The method according to claim 4 , wherein the signal quality threshold is set by the macro base station and notified to the UE by means of broadcasting or by using a radio resource control (RRC) dedicated message, or is set by the UE.

11 . A macro base station, comprising:
a first processor, configured to configure a first measurement gap pattern for user equipment (UE), wherein the first measurement gap pattern refers to a data format that is set by the macro base station for suspending data transmission with the UE when the UE identifies and measures a small base station; a first receiver, configured to receive indication information sent by the UE, wherein the indication information is used to represent that quality of a signal radiated by the small base station and received by the UE is higher than or equal to a preset signal quality threshold, wherein the quality of the signal radiated by the small base station is obtained through measurement by the UE according to the first measurement gap pattern; and wherein the first processor is further configured to: after the first receiver receives the indication information sent by the UE, configure a second measurement gap pattern for the UE, wherein a measurement gap period in the second measurement gap pattern is less than a measurement gap period in the first measurement gap pattern.

12 . The macro base station according to claim 11 , further comprising:
a first transmitter, configured to send, to the UE, carrier frequency information used by the small base station, reception time window information of the signal radiated by the small base station, and a physical cell identity list.
