A kind of the carrier wave convergence transmission method and device of enhancing

Technical field

The present invention relates to the schemes of CA (Carrier Aggregation, carrier wave polymerization), more particularly to based on LTE (Long Term Evolution, long term evolution) system enhancing CA in CSI (Channel Status Information, Channel state information) report scheme.

Background technique

What traditional 3GPP (3rd Generation Partner Project, third generation cooperative partner program) was formulated In LTE system R (Release, version) 10, CA is introduced into as one of key technology, and core concept is user equipment (UE- User Equipment) it can work at the same time over a number of carriers, CA can be improved the peak rate of single UE.In LTE CA, UE is configured a Pcell (Primary Cell, main serving cell), one or more Scell (Secondary Cell, Auxiliary serving cell).For FDD (Frequency Duplex Division, frequency division duplex) LTE, a serving cell includes At least one descending carrier in { descending carrier, a up-link carrier }.For TDD (Time Duplex Division, Time division duplex) LTE, a serving cell includes a carrier wave.In LTE R10, the UE of CA is supported to be at best able to be configured 5 clothes Business cell, and UE can only send PUCCH information on Pcell.In 3GPP R10, CA supports cross-carrier scheduling, i.e., base station is the One carrier wave sends the wireless signal transmission on downlink signaling the second carrier wave of scheduling.Base station utilizes DCI (Downlink Control Information, Downlink Control Information) in CIF (Carrier Indicator Field, carrier wave instructions field) instruction wanted The target carrier of scheduling.CIF is by 3 bit indications positioned at the head DCI.

Pass through in the 66th plenary session (Plenary) of 3GPP RAN (Radio Access Network, wireless access network) One new research topic (RP-142286), i.e. enhancing CA.Enhance in CA project, the serving cell number that maximum is supported rises to 32.

Two kinds of CSI reporting mechanisms are defined in LTE, i.e. A-CSI (Aperiodic CSI, aperiodic CSI) is reported and week The CSI of phase is reported, the former uploads at PUSCH (Physical Uplink Shared CHannel, Physical Uplink Shared Channel) Defeated, the latter is generally transmitted on PUCCH (Physical Uplink Control CHannel, Physical Uplink Control Channel).A- CSI is the DCI (Downlink Control Information, Downlink Control Information) or RARG by upstream format Domain CSI request (Request) in (Random Access Response Grant accesses response scheduling immediately) is triggered, And it is transmitted on the PUSCH scheduled in the DCI of the upstream format or the RARG.The CSI request domain includes 1~2 A bit, when the CSI request domain be 2 bits when, the CSI request domain can indicate the corresponding serving cell of A-CSI or Person CSI process (detailed description is with reference to the table Table7.2.1-1A/B/C in TS36.213).

Summary of the invention

In traditional cellular network, base station (according to the dispatching requirement of oneself) controls the targeted clothes of CSI that UE is reported Cell of being engaged in or CSI process.Inventors discovered through research that since current down channel quality, base station institute are not known in base station The A-CSI of triggering targeted serving cell or CSI process may not be it is optimal, in turn (due to the report of A-CSI) Generate certain ascending resource waste.In view of an extreme case being likely to occur in enhancing CA is that UE is configured with 32 downlinks Carrier wave and 1 up-link carrier are very valuable for the CSI ascending resource reported.Therefore, how efficiently to feed back CSI is A problem to be solved.In addition, inventors discovered through research that, base station is difficult to according to existing 1~2 CSI request domain The association service cell (i.e. the maintenance serving cell for the down channel that A-CSI is reflected) or CSI process of accurate instruction A-CSI (and CSI subframe).One intuitive idea be increase CSI request domain in bit number (in view of at most needing to indicate 32 Descending carrier, required bit number may be higher), however the bit number for increasing CSI request domain can bring the increasing of DCI payload size Add, and then reduces PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel)/ePDCCH The capacity or robustness of (enhanced PDCCH, the PDCCH of enhancing).
