501, micro-base station sends sleep state reference signal.

Under heterogeneous network, the object of micro-base station work is is mostly the traffic carrying capacitys in order to unload macro base station, from promoting the throughput of whole network.Therefore, micro-base station need to send sleep state reference signal so that UE finds this micro-base station in time in sleep state.Wherein, sleep state reference signal can be low-density cell reference signals (Cell-specific Reference Signal, CRS), tracking reference signal (Tracing Reference Signal, TRS) one or more, or in bunch identification information of base station/community.

Wherein, cell reference signals measures for down channel quality or down channel is estimated, for relevant detection and the demodulation of UE end.The specific antenna port that refers to this reference signal and a base station end in community, for example antenna port 0-3, corresponding.So CRS is relevant with antenna port, in the time that antenna number increases, also will increase for the RE quantity of carrying CRS.For example, in 4 antenna situations, will have 24 RE as CRS in every 168 RE, expense exceedes 14.29%, and in the more situation of antenna amount, CRS expense will increase greatly, has increased like this expense of running time-frequency resource, has also improved the power consumption of micro-base station simultaneously.

UE in Idle state can measure this sleep state reference signal in the time receiving the sleep state reference signal of micro-base station broadcast, or can configure this UE by the macro base station under UE measures the sleep state reference signal of micro-base station, for example, macro base station sends single measurement order by high-level signaling to UE, or macro base station to the UE sending measuring cycle, makes this UE according to this measuring period sleep state reference signal being measured by high-level signaling.

UE measures sleep state reference signal and obtains measurement result, and this measurement result can be RSRP, RSRQ, one or more in RSSI or CQI.UE judges according to this measurement result whether it meets predetermined threshold.This threshold value can be predefined by system, specifies to be stored in the threshold value in UE and base station according to agreement, also can be handed down to this UE by macro base station.The concrete unit of this threshold value determines according to the unit of measurement result, for example, when measurement result is RSRP or RSSI, this predetermined threshold is taking power or dB as unit, when measurement result is RSRQ, this predetermined threshold can be a ratio, dimension is 1, and measurement result is that CQI is, this predetermined threshold can be taking dB as unit.

503, message is found in base station.

In the time that UE measures measurement result that sleep state reference signal obtains and is greater than predetermined threshold, UE sends base station to macro base station and finds message, shows that to macro base station UE has found a micro-base station of sleep state.Base station finds that message can report macro base station by Physical Uplink Control Channel PUCCH, and it specifically carries the physical layer identifications that content can comprise this micro-base station of sleep state, can also comprise the measurement result to sleep state reference signal.

505, feedback information.

In the situation that carrying out above-mentioned steps 504, the first reference signal configuration information that micro-base station sends according to macro base station is determined and is sent feedback information to macro base station.Wherein, this feedback information can be a confirmation, and for example ACK/NACK can be also the second reference signal configuration information of being determined voluntarily by micro-base station.Confirmation represents that micro-base station accepts this first reference signal configuration information, configure corresponding reference signal according to this first reference signal configuration information, and inform macro base station, for example, to macro base station feeding back ACK, so that macro base station is determined measurement configuration information according to the first reference signal configuration information for UE, thereby make UE on correct running time-frequency resource, measure this reference signal.

Or the first reference signal configuration information that macro base station sends also can not accepted in micro-base station, can determine voluntarily the second reference signal configuration information, configure corresponding reference signal according to this second reference signal configuration information, for example, in the time that micro-base station receives the first reference signal configuration information of macro base station transmission, judge that whether this first reference signal configuration information is suitable, if the reference signal density configuring in the first reference signal configuration information is excessive (alternatively, be greater than a certain predetermined threshold value), micro-base station is determined the second reference signal configuration information voluntarily, and this second reference signal configuration information is sent to macro base station as feedback information, so that macro base station is determined measurement configuration information according to the second reference signal configuration information for UE, thereby make UE on correct running time-frequency resource, measure this reference signal.Wherein, the second reference signal configuration information can be that micro-base station is determined according to the historical configuration of local reference signal is next, can be to determine according to micro-base station air interference environment around.

In the situation that not carrying out above-mentioned steps 504, this feedback information can be the first reference signal configuration information that micro-base station is determined voluntarily, directly reports the reference signal configuration of oneself to macro base station.So that macro base station is determined measurement configuration information according to the first reference signal configuration information for UE, thereby make UE on correct running time-frequency resource, measure this reference signal.In this case, micro-base station uploading feedback information can be periodically, for example, report the first reference signal configuration information according to predefined report cycle; Also can be triggered and be reported by the predefined trigger condition of system, the embodiment of the present invention limit this.

The measurement configuration information that UE sends according to macro base station is further measured the reference signal of micro-base station, and on the one or more nominated bandwidth that carry in measurement configuration information, the quality of measuring reference signals, reports macro base station by measurement result afterwards.For example, the measurement result reporting according to RSRP/RSRQ is for relatively long average statistics result, as 200ms obtains one-shot measurement result; The measurement result reporting according to CQI is the measurement result in shorter bandwidth of short time relatively, and for example 5ms left and right reports one-shot measurement result, and correspondingly, the nominated bandwidth while adopting CQI need to be set as shorter bandwidth.

508, determine whether to wake up micro-base station.

Macro base station receives after the measurement result that UE reports, and determines whether triggering micro-base station proceed to operating conditions according to measurement result, and in the time that measurement result is greater than predetermined threshold, macro base station wakes micro-base station up, and in the time that measurement result is less than threshold value, macro base station does not wake micro-base station up.For example, in the time that measurement result is RSRP/RSSI/CQI, predetermined threshold is 15dBm, the average power content recording is 20dBm, 20dBm>15dBm, and macro base station wakes micro-base station up, if the average power content recording is 5dBm, macro base station does not wake micro-base station up.Should be understood that in above-mentioned example and use relative power dBm as unit, similarly also can use absolute power W as unit, the embodiment of the present invention does not limit this.In addition,, in the time that measurement result is RSRQ, threshold value need to correspondingly be set to the value that a dimension is 1.In the time that measurement result equals threshold value, can wake up or not wake up, specifically can be specified by agreement, the present invention does not limit.
