Description
Technical field
The present invention relates to the scheme of CA (Carrier Aggregation, carrier wave polymerization) scheduling, more particularly to being based on
The scheme of the CA scheduling of LTE (Long Term Evolution, long term evolution) system.
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 existing LTE system, CA supports cross-carrier scheduling, i.e. base station sends downlink signaling scheduling second in first carrier and carries
Wireless signal transmission on wave.Base station is using in DCI (Downlink Control Information, Downlink Control Information)
CIF (Carrier Indicator Field, carrier wave instructions field) indicates the target carrier to be dispatched.CIF is by being located at DCI head
3 bit indications in portion.The cell index of CIF corresponding with service cell.
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.
For enhancing CA, a method is to increase the bit number (such as increasing to 5 bits) of CIF to ensure that base station can adjust
Spend any target carrier.Another method is to be grouped serving cell, and a scheduling cell is (i.e. for carrying dispatch
Serving cell) target in a serving cell group can only be dispatched.In the above method, the former leads to the increase of DCI total bit number,
And then causes DCI to occupy more interface-free resources or lead to the decline of DCI receptivity；And the latter brings scheduling to limit.
For this problem, the invention discloses the dispatching methods and device in a kind of polymerization of the carrier wave of enhancing.It needs to illustrate
, in the absence of conflict, the feature in embodiments herein and embodiment can be arbitrarily combined with each other.
Summary of the invention
Due to the asymmetry of uplink and downlink business, in cellular network communication, a UE be assigned (for receiving downlink signal
) downlink physical resource can exceed that the ascending physical signal resource (for sending uplink signal).That is: for supporting FDD frame structure
(being deployed in authorization frequency spectrum or unlicensed spectrum) serving cell, descending carrier number that UE is configured may be significantly larger than
Row carrier number.Inventors discovered through research that CIF is the cell index one according to serving cell in existing CA dispatch
One is corresponding, even if a serving cell only includes descending carrier (being not in uplink scheduling DCI for the serving cell), refers to
Show that the CIF value of the serving cell can not be used for uplink scheduling DCI.Inventor through further research, it has been found that, enhancing CA
In transmission, it is more than 8 that a kind of possible scene, which is the carrier wave that can be used for downlink transfer that UE is configured, and what is configured can be used for
The carrier wave of row transmission is less than 8.Under the premise of 3 CIF bits, the possible scheduling portion of a dispatch service cell can be used for down
The carrier wave of row transmission and the carrier wave that can be all used for uplink.
According to above-mentioned analysis, the invention discloses a kind of methods in UE, wherein includes the following steps:
A kind of method in UE, wherein include the following steps:
Step A. receives high-level signaling and the first DCI, and the high-level signaling indicates the cell index of K serving cell, the
