Description

The indicating means of resource distribution and instruction device, base station and terminal

Technical field

The present invention relates to communication technical field, in particular to the instruction device of resource distribution when unauthorized band operation of a kind of LTE system indicating means of resource distribution when unauthorized band operation, a kind of LTE system, a kind of terminal and a kind of base station.

Background technology

Along with sharply increasing of message volume, 3GPP (The3rdGenerationPartnershipProject, 3G (Third Generation) Moblie partnership) mandate frequency range be increasingly not enough to provide higher network capacity. In order to improve the utilization rate of the resource of frequency range further, 3GPP is just discussing how to use unauthorized frequency range under the help authorizing frequency range, such as 2.4GHz and 5GHz frequency range. These unauthorized frequency ranges are presently mainly the systems such as Wi-Fi, bluetooth, radar, medical treatment and are using.

Under normal circumstances, for the access technology authorizing frequency range to design, as LTE (LongTermEvolution, Long Term Evolution) is not suitable for using in unauthorized frequency range, because the requirement that frequency range efficiency and Consumer's Experience are optimized by this kind of access technology of LTE is very high. But, carrier aggregation (CarrierAggregation, CA) function allows and LTE is deployed in unauthorized frequency range becomes possible to. 3GPP proposes the concept of LAA (LTEAssistedAccess, LTE assist access), authorizes the help of frequency range to use unauthorized frequency range by LTE. And unauthorized frequency range can have two kinds of working methods, one to be supplement descending (SDL, SupplementalDownlink), namely only has downlink transfer subframe; Another kind is tdd mode, has both comprised downlink transfer subframe, also comprises uplink subframe. Supplement descending this situation and can only be made by carrier aggregation technology use. And tdd mode is except can using by DC (DualConnectivity, doubly-linked leads to), it is also possible to independently from. As shown in Figure 1.

Compared to Wi-Fi system, the LTE system being operated in unauthorized frequency range has the ability to provide higher frequency range efficiency and bigger coverage effect, is simultaneously based on same core net and allows data traffic authorize seamless switching between frequency range and unauthorized frequency range. For user, it means that better broadband experience, higher speed, better stability and mobile facility.

The existing access technology used in unauthorized frequency range, such as Wi-Fi, has more weak capacity of resisting disturbance. In order to avoid interference, Wi-Fi system devises a lot of interference and avoids rule, such as CSMA/CD (CarrierSenseMultipleAccess/CollisionDetection, csma/collision detection method), the ultimate principle of this method is the AP (AccessPoint of Wi-Fi, access point) or terminal before sending signaling or data, want around first Monitor detection, whether have other AP or other-end sending/receiving signaling or data, if having, then continuing to monitor, not having until listening to; If no, then generate a random number as back off time, in this back off time, if signaling or data transmission not detected, then after back off time terminates, AP or terminal can start to send signaling or data. This process is as shown in Figure 2.

In order to ensure the fair coexistence with WIFI, LAA proposes FBE (FramebasedEquipment, based on the equipment of frame structure) and LBE (LoadbasedEquipment, based on the equipment of load) multiple listem-before-talk mechanism. LTE is when using unauthorized frequency range, it is necessary to channel idle first detected, could send so that can not continuously transmit in unauthorized frequency range. It addition, in order to ensure making full use of and the accuracy of channel idle detection of frequency range, European Union also specifies, the bandwidth occupancy in unauthorized frequency range will more than more than 80%. Further, since the scope that LAASCell (SecondaryCell, secondary cell) covers is little, the UE number that can dispatch is few, so the ResourceBlock (RB, Resource Block) of each UE distribution will compare many.

And resource distribution bit number shared by (ResourceAllocation) territory is relatively larger in traditional DCI (DownlinkControlInformation, Downlink Control Information) signaling. Concrete determines according to system bandwidth, and what table 1 provided is the method carrying out indexed resource distribution with the method for salary distribution of type0. Left-hand column instruction system bandwidth, indicate with the RB number that system bandwidth takies, the right instruction is RBG (Resourceblockgroup, Resource Block group) size, specifically N number of RB, such as, when system bandwidth is 10 RB, the size of RBG is exactly 1 RB, and so, ResourceAllocation territory needs to take 10bit and indicates the resource of 10 RB to distribute, and when certain bit is 1, identify RB corresponding for this bit and distribute to this UE, otherwise when for 0, identify RB corresponding for this bit and be not assigned to this UE.

Table 1Type0resourceallocationRBGsizevs.DownlinkSystemBandwidt h

For 50RB, provide schematic diagram, as shown in Figure 3. 3 RB mono-group, need altogether 17 bit to indicate.

What Fig. 4 provided is carry out indexed resource distribution with the resource distribution mode of type1, equally for bandwidth for 50RB. Being divided into three territories in Fig. 4 in ResourceAllocation territory, first territory takies bit number and isInstruction uses the RB of which subset (subset), is use the 3rd here. Here the P that capitalizes indicates two meanings: one when being meant to 50RB, and a RBG is P (3) individual RB; Another is meant to P (3) the individual subset being divided into by 50RB as shown in Figure 4. Second territory takies 1 bit, is 0 expression left-justify distribution, is 1 expression Right Aligns distribution. The size that 3rd territory takies bit number is exactly the bit number that the bit number in the resource distribution mode of type0 deducts above two territories, 14bit.

And the resource distribution mode of Type2 comes in the method for indexed resource distribution, pass through DCIformat1A, 1Bor1D uses 1bit to indicate the localized (centralized) or distributed (distributed) distribution method using Type2, and format1C is the method for distributed all the time. About the centralised allocation method of Type2, calculate RB_start (Resource Block starting point) and length (length) according to RIV (resource indication information) indicating gage; And it is if distributed it is known that RB_start and gap (interval). Gap value such as table 2 below.

Table 2:valuesvs.DownlinkSystemBandwidth
