Description

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

Technical field

The present invention relates to fields of communication technology, in particular to a kind of money of LTE system in unauthorized band operation The instruction device of the resource allocation in unauthorized band operation of indicating means, LTE system of source distribution a kind of, a kind of terminal and A kind of base station.

Background technique

With the sharp increase of message volume, 3GPP (The 3^rdGeneration Partnership Project, 3G (Third Generation) Moblie partnership) authorized spectrum band it is less and less adequate to provide higher network capacity.In order to further mention The utilization rate of high band resource, 3GPP just discussing how with the help of authorized spectrum band using unauthorized frequency range, such as 2.4GHz and 5GHz frequency range.These unauthorized frequency ranges are presently mainly that the systems such as Wi-Fi, bluetooth, radar, medical treatment are using.

Under normal conditions, be the access technology of the design of authorized spectrum band, as LTE (Long Term Evolution, for a long time Evolution) be not suitable for using in unauthorized frequency range, because this kind of access technology of LTE wants frequency range efficiency and user experience optimization Ask very high.However, carrier wave polymerization (Carrier Aggregation, CA) function allows and LTE is deployed in unauthorized frequency range becomes It may.3GPP proposes the concept of LAA (access of LTE Assisted Access, LTE auxiliary), by the side of LTE authorized spectrum band It helps using unauthorized frequency range.And unauthorized frequency range can there are two types of working method, one is supplement downlink (SDL, Supplemental Downlink), i.e. only downlink transfer subframe；Another kind is tdd mode, both includes downlink transfer subframe, It also include uplink subframe.Supplementing downlink such case can only use by carrier aggregation technology.And tdd mode is in addition to can To be used by DC (Dual Connectivity, doubly-linked are logical), can also independently use.As shown in Figure 1.

Compared to Wi-Fi system, the LTE system in unauthorized frequency range that works has the ability to provide higher frequency range efficiency and more Big coverage effect, while allowing data traffic between authorized spectrum band and unauthorized frequency range without seaming and cutting based on the same core net It changes.For users, it means that better broadband experience, higher rate, better stability and mobile convenience.

The existing access technology used in unauthorized frequency range, such as Wi-Fi have weaker anti-interference ability.In order to It avoids interfering, Wi-Fi system devises many interference and avoids rule, such as CSMA/CD (Carrier Sense Multiple Access/Collision Detection, csma/collision detection method), the basic principle of this method It is that either terminal wants first Monitor detection week before sending signaling or data by the AP (Access Point, access point) of Wi-Fi Whether have other APs or other terminals in transmission/reception signaling or data, if so, then continuing to monitor, until listening to not if enclosing Until having；If no, generating a random number as back off time, in this back off time, if not detected letter It enables or data is transmitted, then AP or terminal can start to send signaling or data after back off time terminates.The process is as schemed Shown in 2.

In order to guarantee the fair coexistence with WIFI, LAA proposes FBE, and (Frame based Equipment is based on frame knot The equipment of structure) and LBE (Load based Equipment, the equipment based on load) a variety of listem-before-talk mechanism.LTE is being used It when unauthorized frequency range, needs first to detect channel idle, could send, so that cannot be continuously transmitted in unauthorized frequency range.In addition, In order to guarantee the accuracy of frequency range made full use of with channel idle detection, European Union is also provided, the bandwidth in unauthorized frequency range Occupancy will be more than 80% or more.In addition, can be adjusted since the range of LAA SCell (Secondary Cell, secondary cell) covering is small The UE number of degree is few, so the Resource Block (RB, resource block) of each UE distribution will be relatively more.

And resource allocation in traditional DCI (Downlink Control Information, Downlink Control Information) signaling Bit number shared by the domain (Resource Allocation) is bigger.Specifically determined according to system bandwidth, what table 1 provided It is the method with the method for salary distribution of type 0 to indicate resource allocation.Left-hand column indicates system bandwidth, is occupied with system bandwidth RB number indicates, the right instruction be RBG (Resource block group, resource block group) size, specifically N number of RB, For example, when system bandwidth is 10 RB, the size of RBG is exactly 1 RB, in this way, the domain Resource Allocation needs to account for The resource allocation of 10 RB is indicated with 10bit, and when some bit is 1, is identified the corresponding RB of the bit and distributed to the UE, it is no Then when for 0, identifies the corresponding RB of the bit and be not assigned to the UE.

1 Type of table, 0 resource allocation RBG size vs.Downlink System Bandwidth

By taking 50RB as an example, schematic diagram is provided, as shown in Figure 3.3 mono- group of RB, 17 bit is needed to indicate altogether.

What Fig. 4 was provided is to indicate resource allocation with the resource distribution mode of type 1, equally by taking bandwidth is 50RB as an example. It is divided into three domains in Fig. 4 in the domain Resource Allocation, first domain occupies bit number and beInstruction uses the The RB of several subset (subset) is using third here.Here the P capitalized indicates two meanings: one means 50RB When, a RBG is P (3) a RB；Another, which means, is divided into P as shown in Figure 4 (3) a subset for 50RB.Second domain accounts for With 1 bit, left-justify distribution is indicated for 0, indicates Right Aligns distribution for 1.Third domain occupy bit number size be exactly Bit number in the resource distribution mode of type0 subtracts the bit number in two domains in front, 14bit.

And in method of the resource distribution mode of Type2 to indicate resource allocation, pass through DCI format1A, 1B or 1D The localized (centralization) or distributed (distribution) distribution method using Type2 are indicated using 1bit, and Format 1C is the method for distributed always.About the centralised allocation method of Type2, according to RIV (resource instruction letter Breath) it indicates to calculate RB_start (resource block starting point) and length (length)；And if it is distributed, it is known that RB_ Start and gap (interval).Gap value such as the following table 2.
