Description

The management method of the auxiliary serving cell in unlicensed spectrum, system and base station

Technical field

The present invention relates to communication technical field, the management system of the auxiliary serving cell in the management method, a kind of unlicensed spectrum of the auxiliary serving cell in a kind of unlicensed spectrum and a kind of base station.

Background technology

Along with the sharply increase of message volume, 3GPP (3rdGenerationPartnershipProject, third generation partner program) authorize frequency spectrum to be more and more not enough to provide higher network capacity, and WLAN (WirelessLocalAreaNetworks, WLAN (wireless local area network)) unlicensed spectrum (section) that uses, also can provide higher throughput for almost static user to a great extent.But the shortcoming of WLAN is poor user experience, such as, WLAN cannot ensure QoS of survice (QualityofService, service quality) demand, can not support mobile management etc.

But, from current development trend, WLAN and LTE (LongTermEvolution, Long Term Evolution) base station more and more tends to colocation site, therefore the technical scheme merged by LTE and WLAN is proposed in correlation technique, namely WLANAP (AccessPoint, access point) as a Scell (SecondaryCell, auxiliary community) (calling WLANScell in the following text) controlled by LTE base station in the mode of dualconnectivity (dual link), thus improve UE (User further, user) throughput and WLAN on the QoS of user, also can ensure to support UE mobility simultaneously.

Simultaneously, LTE also wishes to use unlicensed spectrum by authorizing the cell (community) on frequency spectrum to help LTE at LTE, namely LAA (LTEAssistedAccess, the access technology that LTE is auxiliary), namely LTE wishes, under the help of authorizing frequency spectrum, unlicensed spectrum to be used with the access way of LTE.In order to ensure the fairness with WLAN in unlicensed spectrum, LAAScell introduces LBT (ListenBeforeTalk, listem-before-talk) mechanism, make LAAScell before use unlicensed spectrum, also need first to listen lower channel whether can use, if the channel heard is unavailable, then do not use.So, LAAScell and WLANScell is the same, it unlicensed spectrum is also discontinuous transmission, like this, the same carrier wave that LAAScell and WLANScell may take, but at present on a carrier wave, a Scell can only be had, so just there will be the select permeability between LAAScell and WLANScell.

And because the interpolation of Scell, removal and switching are the RRM (RadioResourceManagement based on UE, RRM) measurement report decides, and at present in measurement, the measurement configuration of the cell configuring LTE carrier frequency is only supported in base station, and UE also only supports that the interpolation of the cell of LTE carrier frequency/removal is measured and measurement reports.And do not support that the interpolation of WLANScell/removal measurement configuration and measurement report, do not support that the replacement of WLANScell and LAAScell measurement configuration and measurement report yet.

The following describes traditional measurement configuration and measurement report, have following parameter for each measurement configuration:

(1) numbering is measured: a just number value.

(2) measuring object: measure which kind of system (such as UTRA (UniversalTerrestrialRadioAccess, the general designation of the wireless and network standard of 3GPP definition), EUTRA (electronics-UTRA)) which kind of carrier frequency is (such as, carrier frequency #1), and/or which cell (such as provides a celllist, comprise cell#1,2 ...).

(3) measure interval: if different-frequency measure, then need one to measure interval, in this measurement interlude, UE will disconnect with Serving cell, and is switched to by receiver on the carrier frequency of needs measurement, thus carries out alien frequencies signal measurement.

(4) measurement triggering event: such as Event (event) A3: an adjacent cell offset larger than Serving cell (report is biased) (namely needs the RSRP (ReferenceSignalReceivingPower of the adjacent cell measured, Reference Signal Received Power)/RSRQ (ReferenceSignalReceivingQuality, reference signal received energy) offset larger than Serving cell, then trigger measurement report, and provide the value of offset).

(5) measurement report configuration comprises: periodic report or aperiodicity are reported, report number of times, report how many cell etc. satisfied condition.

And the report of UE is: when UE measurement finds that there is the EventA3 said cell satisfied (4) the inside, measurement report is sent according to measurement report configuration, and feedback measures numbering in measurement report, just can know it is the measurement report using EventA3 to trigger according to this measurement numbering base station here, can measuring object be determined simultaneously.

To sum up, when how there is LAAScell and WLANScell in unlicensed spectrum simultaneously, by the measurement parameter measuring to RRM different in terminal configuration unlicensed spectrum, base station added Scell according to the RRM measurement report of terminal, removes, replace and the management such as switching, thus make terminal be connected on a best Scell all the time, improve the throughput of terminal and ensure the service quality of business, promoting Consumer's Experience becomes technical problem urgently to be resolved hurrily.
