Description

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

Technical field

The present invention relates to fields of communication technology, in particular to a kind of pipe of the auxiliary serving cell in unlicensed spectrum Reason method, a kind of management system of auxiliary serving cell in unlicensed spectrum and a kind of base station.

Background technique

With the sharp increase of message volume, 3GPP (3rd Generation Partnership Project, third For partner program) authorization frequency spectrum is less and less adequate to provide higher network capacity, and WLAN (Wireless Local Area Networks, WLAN) unlicensed spectrum (section) that uses also can be largely almost static use Family provides higher handling capacity.But the shortcomings that WLAN, is poor user experience, for example, WLAN not can guarantee QoS of survice (Quality of Service, service quality) demand, cannot support mobile management etc..

However, from the point of view of current development trend, WLAN and LTE (Long Term Evolution, long term evolution) base station Increasingly tend to colocation site, therefore proposes the technical solution for merging LTE with WLAN, that is, WLAN in the related technology AP (Access Point, access point) as Scell (Secondary Cell, secondary cell) (calling WLAN Scell in the following text) with The mode of dual connectivity (dual link) is controlled by LTE base station, to further increase gulping down for UE (User, user) The QoS of user on the amount of spitting and WLAN, while also can guarantee and supporting UE mobility.

Meanwhile LTE also wishes to help LTE to use unlicensed spectrum by authorizing the cell (cell) on frequency spectrum in LTE, Namely LAA (access technology of LTE Assisted Access, LTE auxiliary), i.e. LTE wishes with the help of authorizing frequency spectrum, By unlicensed spectrum with the access way of LTE come using.In order to guarantee the fairness in unlicensed spectrum with WLAN, LAA Scell introduces LBT (Listen Before Talk, listem-before-talk) mechanism, make LAA Scell using unlicensed spectrum it Before, it is also desirable to it first listens whether lower channel can be used, if the channel heard is unavailable, does not use.So LAA Scell with WLAN Scell is the same, is also discontinuous transmission in unlicensed spectrum, in this way, LAA Scell and WLAN Scell may be accounted for A same carrier wave, but at present on a carrier wave, as soon as there can only be a Scell, so will appear LAA Select permeability between Scell and WLAN Scell.

And because of the addition of Scell, removal and switching are RRM (the Radio Resource based on UE Management, wireless resource management) measurement report determines, and at present in terms of measurement, base station only supports configuration LTE to carry The measuring configuration of the cell of frequency, UE also only support addition/removal measurement of the cell of LTE carrier frequency and measurement to report.Without supporting The addition of WLAN Scell/removal measuring configuration and measurement report, and the replacement of WLAN Scell and LAA Scell is not supported to survey yet Amount configuration and measurement report.

Illustratively traditional measuring configuration and measurement report below, has following parameter for each measuring configuration:

(1) measurement number: an only number value.

(2) measurement object: measure which kind of system (such as UTRA (Universal Terrestrial Radio Access, The general designation for the wireless and network standard that 3GPP is defined), EUTRA (electronics-UTRA)) which kind of carrier frequency (for example, carrier frequency #1), and/or Which cell (for example provides a cell list, includes cell#1,2 ...).

(3) measurement interval: if it is different-frequency measure, then a measurement interval, in the measurement interval time, UE are needed It to be disconnected with serving cell, and receiver is switched on the carrier frequency for needing to measure, to carry out alien frequencies signal measurement.

(4) measure trigger event: such as Event (event) A3: an adjacent cell offset bigger than serving cell (reports inclined Set) ((Reference Signal Receiving Power, reference signal receive function to the RSRP for the adjacent cell for needing to measure Rate)/RSRQ (Reference Signal Receiving Quality, reference signal receive energy) is one bigger than serving cell Offset then triggers measurement report, and provides the value of offset).

(5) measurement report configuration includes: periodic report or how many acyclic reporting, report number, report satisfactions The cell etc. of condition.

And the report of UE is are as follows: when UE measurement discovery has cell to meet the Event A3 said inside (4), reported according to measurement It accuses configuration and sends measurement report, and the feedback measurement number in measurement report, this is just able to know that according to the measurement number base station In be the measurement report triggered using Event A3, while can determine measurement object.

To sum up, how when existing simultaneously LAA Scell and WLAN Scell in unlicensed spectrum, by being configured to terminal The measurement parameter of different RRM measurement, adds base station to Scell according to the RRM measurement report of terminal in unlicensed spectrum The management such as add, remove, replace and switch, so that terminal is connected to always on a best Scell, improves gulping down for terminal The amount of spitting and the service quality for guaranteeing business, promoting user experience becomes technical problem urgently to be resolved.
