Description

A kind of method, apparatus of resource allocation and a kind of communication system

Technical field

The present invention relates to the communications field, more particularly to a kind of method, apparatus of resource allocation and a kind of communication system.

Background technology

At present, the wireless communication system of main flow is used based on the coherent demodulation for having reference signal, therefore, in channel radio In letter system, the effect of reference signal is quite important.For example, the multiple-input and multiple-output for multiple antennas（Multiple Input Multiple Output, MIMO）Wireless communication system, the design of reference signal is just very crucial, especially, when MIMO is wireless It is also corresponding higher to the design requirement of reference signal when the antenna number of communication system is more.With Long Term Evolution（Long Term Evolution, LTE）The 8th version（Release-8, Rel-8）Exemplified by system, it supports most 4 transmitting antennas altogether Configuration, the reference signal used is the cell specific reference signal based on antenna port（Cell-specific Reference Signal, CRS）.CRS's is configured with three kinds of 1 antenna, 2 antennas and 4 antennas situations.In other words, how many actual physics hair Penetrate antenna, it is necessary to which how many different CRS signal supports the demodulation to signal on every antenna.

The demodulated reference signal based on dedicated pilot has been gradually introducing in version in LTE Rel-8 and its afterwards （DeModulation Reference Signal, DM-RS）.DM-RS reference signals are the layers in the spatial parallelism of actual use It is upper to send rather than only sent on physical antenna port, for example, when there are 4 transmitting antennas, needed using CRS for every hair When penetrating antenna assignment reference signal, and using DM-RS, even if actual use is 4 physical antennas, if spatially there was only 2 Layer, then still only need 2 layers of DM-RS；The basic mode for realizing DM-RS is prelisted used in the DM-RS of each user Code vector is identical with precoding vector used in data.From the foregoing it may be appreciated that DM-RS is more flexible than CRS, efficiency is more Height, therefore, current trend are that the place that can use DM-RS uses DM-RS as much as possible.

It is user resource allocation when using DM-RS, such as Physical Resource Block（Physical Resource Block, PRB）Mode have two kinds of continuous dispensing and distributed allocation.From user equipment（User Equipment, UE）The receiver of side Angle considers, if can carry out united channel using multiple continuous PRB as much as possible when carrying out channel estimation Estimation, then it can ensure the performance of UE receivers to greatest extent.Certainly, joined using the DM-RS on multiple continuous PRB The channel estimation of conjunction has a precondition, i.e. identical precoding vector has been used on adjacent PRB, this premise energy It is continuous enough to ensure the equivalent channel on adjacent PRB.The precoding used due to the precoding vector that DM-RS is used with data Vector is identical, therefore, in order to reach the maximization of capacity, base station（eNodeB）The scheduler of this side can be according to acquisition Downlink channel condition information（Channel State Information, CSI）Different precoding vectors is distributed for each PRB, In other words, the precoding vector distributed on adjacent PRB can be with identical, can also be different.Due to using on multiple continuous PRB DM-RS carry out united channel estimation and possess foregoing precondition, therefore, this distributes precoding on adjacent PRB The uncertainty of vector, actually mean that can not be that UE carries out joint channel estimation using the DM-RS on multiple continuous PRB There is provided and ensure.

In order to solve the above problems, existing LTE protocol introduces the concept of PRB bindings in Rel-10 versions, goes forward side by side one Define precoding resource block group to step（Pre-coding Resource block Group, PRG）.When UE is configured to pass Defeated pattern 9（Transport Mode9, TM9）When, the PRG that each UE is allocated formed objects is that each PRG includes identical number The PRB of amount, and identical precoding vector has been used on all PRB of the PRG.

However, the channel circumstance that each UE is run into practical application scene is diversified, each UE channel conditions All different, therefore, the method for the distribution PRG that above-mentioned prior art provides, the defects of its is maximum, is under every kind of configuration Bandwidth, PRG sizes are fixed, all using the PRG of fixed size are not optimal to all users using TM9 in cell 's.Typically, the scope of generally only tens meters to 100 meters of the coverage of cell, and the UE numbers to be communicated under cell Less, the resource to each UE distribution is more, and its wireless channel more stable i.e. time-varying characteristics of channel and frequency selective characteristic are all It is smaller.In such a scenario, the PRG of fixed size of the existing LTE protocol defined in Rel-10 is just no longer applicable.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, the every other embodiment that those skilled in the art are obtained, belongs to the scope of protection of the invention.

Accompanying drawing 1 is referred to, is a kind of method flow schematic diagram of resource allocation provided in an embodiment of the present invention, mainly includes Step S101 and step S102, describe in detail as follows：

S101, it is S to distribute at least one set of size for the first user equipment₁First resource block and be second user equipment It is S to distribute at least one set of size₂Secondary resource block.

In embodiments of the present invention, first resource block is that the first user equipment carries out Radio Resource used in radio communication Unit, Secondary resource block be second user equipment carry out radio communication used in radio resource units, the first user equipment and Second user equipment can be two user equipmenies different under cell, and the first user equipment and second user equipment carry out nothing Radio Resource used in line communication can be Physical Resource Block PRB.In embodiments of the present invention, if being not particularly illustrated, one Group resource block（Including first resource block and Secondary resource block）The precoding resource block group that can be made up of some PRB （Pre-coding Resource block Group, PRG）An or resource block group being made up of some PRB（Resource Block Group, RBG）；Substantially, RBG and PRG is allocated to user equipment and wirelessly provided used in radio communication Source, relation between the two is that a RBG may include one or more PRG, and for same PRG, it is included all All data are sent on PRB by identical precoding vector.

It is at least one set of to being distributed for the first user equipment exemplified by only thinking the resource block of user equipment distribution below and being PRG Size is S₁First resource block and be that to distribute at least one set of size be S to second user equipment₂Secondary resource block said It is bright.It should be noted that in the case of not illustrating, the method for being user equipment distribution PRG be applied equally to for User equipment distributes RBG.

In the present embodiment, S₁Size can be differently configured from S₂.I.e. in the present embodiment, evolution base station can be directed to different User equipment distributes different size of resource block.That is, one or more user equipmenies can be allocated be specific to this one The resource block of individual or multiple user equipmenies, rather than all resource blocks are defined in the same size, improve resource units The flexibility of distribution.

As it was previously stated, under cell, although the coverage of the website of cell diminishes, because application scenarios master If building intensive city and interior, therefore overlay environment may become more complicated.So-called cell is also referred to as micro- Cell（microcell）, it is that covering radius is smaller under macrocell（About 30m~300m）, transmission power it is relatively low（Typically exist Below 1W）The relatively low cell with the antenna of emittor/receiver, its signal propagate the sight progress mainly along street.Such as It is that signal propagates schematic diagram in cell shown in Fig. 2.In the example of accompanying drawing 2, the first user equipment（UE1）Receive cell Signal and second user equipment（UE2）The signal of the cell received has larger difference, i.e. the first user equipment receives Signal the relative time delay from different reflection sources it is smaller, and the signal that second user equipment receives comes from different reflection sources Signal relative time delay it is larger, the feature that this phenomenon corresponds to wireless channel is exactly the time delay of the channel of the first user equipment Extension is smaller, and the delay spread of the channel of second user equipment is larger.So-called delay spread, refer to that multipath effect makes reception signal The phenomenon of pulse width extension.In order that each user equipment obtains optimum beam figuration gain and receiver performance, in this hair In bright embodiment, if the channel delay spread of the first user equipment is smaller relative to the channel delay spread of second user equipment, Be then the first user equipment allocated size relative to the first resource block distributed for the second user equipment size compared with Big Secondary resource block, i.e., what it is if the distribution of the first user equipment is that size is S₁First resource block and set for second user What back-up was matched somebody with somebody is that size is S₂Secondary resource block when, S₁More than S₂.By taking accompanying drawing 2 as an example, to the first user equipment（UE1）For, Because the channel delay spread of the first user equipment is relative to second user equipment（UE2）Channel delay spread it is smaller, can be with The first user equipment will be distributed to（UE1）The granularity of resource divide thicker, second user equipment will be distributed to（UE2）'s The granularity of resource divides thinner, as the first user equipment（UE1）The PRG of distribution size S₁Set more than for second user It is standby（UE2）The PRG of distribution size S₂。

For set wireless communication system, on an identical running time-frequency resource can spatially parallel transmission data flow Number service rating（Rank）To characterize, i.e. on identical running time-frequency resource, the data of user equipment spatially parallel transmission Flow amount is bigger, and the Rank that it can be supported is higher, and Rank span is [1, min（Ntx, Nrx）], i.e. Rank is most Small value is 1, and maximum is reception antenna quantity and transmission antenna number in the wireless communication system being made up of user equipment and base station The smaller value of amount between the two.For example, evolution base station（eNB）With 4 antennas, user equipment（UE）With 2 antennas, then Rank Span be [1,2]；If eNB and UE have 4 antennas, Rank span is [Isosorbide-5-Nitrae].For eNB's and UE When dual-mode antenna number is fixed, Rank specific value is determined by the maximum that the degree of parallelism of wireless channel is wireless channel matrix H order It is fixed.In the case of the channel delay spread of the first user equipment and the roughly the same channel delay spread of second user equipment, It is S to distribute at least one set of size as the present invention for the first user equipment₁First resource block and be second user equipment point It is S with least one set of size₂Secondary resource block another embodiment, if on identical running time-frequency resource, first user Equipment spatially parallel transmission number of data streams relative to the second user equipment spatially parallel transmission data Flow amount is bigger, then is the first user equipment allocated size relative to the first resource distributed for the second user equipment The larger Secondary resource block of the size of block, i.e., what it is if the distribution of the first user equipment is that size is S₁PRG and for second use Family equipment distribution is that size is S₂PRG when, S₁More than S₂.Usually, the Rank used during transmission is higher, to channel estimation Requirement it is also higher, and PRG is bigger, also higher to the precision of channel estimation and demodulation.Therefore, if according to base station（eNB） With user equipment（UE）Between actual transmissions when order used size configure different PRG size, i.e., to base station（eNB）With User equipment（UE）Between actual transmissions when the larger user equipment of order used distribute larger PRG, then be advantageous to user equipment Improve channel estimation and the precision of demodulation.

Due to using the specific reference signal of cell（Cell-specific Reference Signal, CRS）Use , it is necessary to which the channel number of estimation is proportional to the reception antenna number of user equipment for the equipment of family, i.e. user equipment is supported Number of antennas is more, it is necessary to which the channel number of estimation is also more for the UE using CRS.In embodiments of the present invention, if The number of antennas that the number of antennas that one user equipment is supported is supported relative to second user equipment is more, then is described first User equipment allocated size is relative to the larger Secondary resource of the size of the first resource block distributed for the second user equipment Block, i.e., what it is if the distribution of the first user equipment is that size is S₁PRG and be second user equipment distribution be that size is S₂'s During PRG, S₁More than S₂。

It is S to distribute at least one set of size as the present invention for the first user equipment₁First resource block and for second use It is S that family equipment, which distributes at least one set of size,₂Secondary resource block another embodiment, can be made according to first user equipment The second transmission mode that first transmission mode and the second user equipment use, for first user equipment distribute to Few one group of size is S₁First resource block and to distribute at least one set of size for the second user equipment be S₂Secondary resource Block so that the first transmission mode corresponds to first resource block and the second transmission mode corresponds to Secondary resource block.For example, definition the One transmission mode TM11a and the second transmission mode TM11b, and under the first transmission mode TM11a corresponding to various system bandwidths PRG sizes are as shown in table 1-a, and PRG sizes corresponding to various system bandwidths are as shown in table 1-b under the second transmission mode TM11b：

Table 1-a

Table 1-b

Then it is described first when the transmission mode for directly or indirectly indicating to use to the first user equipment is TM11a The first resource block of user equipment distribution is the PRG under system bandwidth shown in table 1-a；When direct or indirect to second user equipment When the transmission mode that ground instruction uses is TM11b, then the Secondary resource block for second user equipment distribution is shown in table 1-b PRG under system bandwidth, in this way, the first transmission mode is corresponding to the PRG and the second transmission mode under system bandwidth shown in table 1-a Corresponding to the PRG under system bandwidth shown in table 1-b.The benefit of this method is the information phase by PRG size and transmission mode Mutual correlation, it is not necessary to extraly individually indicated by other signalings to user equipment, and transmission mode can also dynamically, soon Change fastly, thus also remain enough flexibilities.

It should be noted that the various embodiments described above are assuming that communication loop residing for the first user equipment and second user equipment The resource block allocation strategy made on the premise of the difference of border, if communication environment residing for the first user equipment and second user equipment is complete It is exactly the same, for example, the channel delay spread of the first user equipment it is identical with the channel delay spread of second user equipment, identical Running time-frequency resource on, the first user equipment spatially parallel transmission number of data streams be equal to second user equipment spatially The number of antennas that the number of data streams of parallel transmission, the first user equipment are supported is equal to the antenna that second user equipment is supported The first transmission mode that number or the first user equipment use and the second transmission mode that second user equipment uses are mutually equal Deng then It is not necessary to distribute different size of resource block for the first user equipment and second user equipment, you can be described first User equipment allocated size and the equal-sized Secondary resource block of the first resource block for second user equipment distribution.

As it was previously stated, RBG and PRG, which are allocated to user equipment, carries out Radio Resource used in radio communication, both Between relation be that a RBG may include one or more PRG.It is at least one set of for the distribution of the first user equipment as the present invention Size is S₁First resource block and be that to distribute at least one set of size be S to second user equipment₂Secondary resource block another reality Example is applied, can be for first user equipment（UE1）It is S to distribute at least one size₁The first RBG and described first At least one first PRG is distributed for first user equipment in RBG, and is the second user equipment（UE2）Distribution is extremely A few size is S₂The 2nd RBG and be the second user equipment distribution at least one second in the 2nd RBG PRG.As shown in Figure 3, distribute RBG i.e. RBG that a size is 9PRBs for the first user equipment and include 9 PRB, and It is that first user equipment distributes two PRG in the RBG, wherein, a PRG size is that 4PRBs is that the PRG includes 4 PRB, another PRG size are that 5PRBs is that the PRG includes 5 PRB；It is 8PRBs's to distribute a size for second user equipment RBG is that the RBG includes 8 PRB, and is that the second user equipment distributes two PRG in the RBG, wherein, a PRG Size is that 3PRBs is that the PRG includes 3 PRB, and another PRG size is that 5PRBs is that the PRG includes 5 PRB.

It is above-mentioned be that to distribute at least one size be S to the first user equipment₁The first RBG and be in the first RBG First user equipment is distributed at least one first PRG embodiment, and it in the first RBG is described first that can be User equipment allocated size is all S '₁At least one first PRG, will be after the first RBG be divided into several the first PRG Distribute first user equipment；It is above-mentioned be that to distribute at least one size be S to second user equipment₂The 2nd RBG and in institute State in the 2nd RBG and distributed for the second user equipment at least one 2nd PRG embodiment, can be described second It is that the second user equipment allocated size is all S ' in RBG₂At least one 2nd PRG, will the 2nd RBG be divided into The distribution second user equipment after after several the 2nd PRG.As shown in Figure 4, it is the size of the first user equipment distribution 11PRBs RBG is that the RBG includes 11 PRB, is the distribution of the first user equipment two PRG, each PRG in the RBG Size 5PRBs is that each RBG includes 5 PRB；RBG for the size 9PRBs of the first user equipment distribution is that the RBG includes 9 PRB, it is that the second user equipment distributes two PRG in the RBG, each PRG sizes 4PRBs is that each RBG includes 4 PRB。

It is S in the size distributed for first user equipment₁The first RBG in for first user equipment distribution it is big Small is all S '₁An at least one PRG when, as far as possible cause the S₁It is the S '₁Integral multiple；Similarly, for described The size of two user equipmenies distribution is S₂The 2nd RBG in for the second user equipment allocated size be all S '₂It is at least one During two PRG, cause the S as far as possible₂It is the S '₂Integral multiple.As shown in Figure 5, it is the size of the first user equipment distribution 12PRBs RBG is that the RBG includes 12 PRB, is the distribution of the first user equipment two PRG, each PRG in the RBG Size 6PRBs is that each RBG includes 6 PRB；RBG for the size 10PRBs of the first user equipment distribution is that the RBG includes 10 Individual PRB, it is that the second user equipment distributes two PRG in the RBG, each PRG sizes 5PRBs is that each RBG includes 5 PRB.Because whole resource is allocated in units of RBG, therefore, when the PRG size for being sized to divide exactly RBG, It is to be carried out in a RBG without across multiple RBG, here it is the distribution method of the example of accompanying drawing 5 when ensure that distribution PRG Where advantage.

It is S to distribute at least one size as the present invention for the first user equipment₁The first RBG and in the first RBG It is interior to distribute at least one first PRG for first user equipment, and be that at least one size of second user equipment distribution is S₂RBG and be another embodiment that the second user equipment distributes at least one 2nd PRG in the 2nd RBG, can To be as S in the size₁The first RBG in for first user equipment distribute multiple first PRG of different sizes, and The size that the first PRG larger in multiple first PRG of different sizes is distributed for first user equipment is less first The integral multiple of PRG size, it is S in the size₂The 2nd RBG in for the second user equipment distribute it is multiple of different sizes The 2nd PRG, and the big of the 2nd PRG larger in multiple 2nd PRG of different sizes is distributed for the second user equipment The integral multiple of the small size for being less 2nd PRG.As shown in Figure 6, distributing a size for the first user equipment is 15PRBs RBG is that the RBG includes 15 PRB, and is that first user equipment distributes two PRG in the RBG, its In, a PRG size is that 10PRBs is that the PRG includes 10 PRB, and another PRG size is that 5PRBs is that the PRG includes 5 PRB；RBG i.e. RBG that a size is 8PRBs is distributed for second user equipment and includes 12 PRB, and is in the RBG The second user equipment distributes two PRG, wherein, a PRG size is that 8PRBs is that the PRG includes 8 PRB, another PRG sizes are that 4PRBs is that the PRG includes 4 PRB.

In embodiments of the present invention, can be that all system bandwidths supported user equipment distribute different PRG, it is right In cell, by then for improving local handling up geographically, it is thus possible to only distribute big system bandwidth, i.e., in the present invention In embodiment, only different size of PRG can be distributed for big system bandwidth.

In the prior art, to different communication environment, for example, under the conditions of different channels, different transmission mode under user set Standby, RBG sizes are all that fixed and this value is not too much big, in this way, can bring about pole to the particularly preferred user equipment of channel condition The waste of big signaling consumption.Because RBG sizes are smaller, it is necessary to indicate that these RBG signaling is more, for example, with a width of 20MHz system shares 100PRBs, is distributed according to RBG sizes are 4PRBs, then needs 100/4=25 kind of resource location of instruction； If the channel condition of some user equipment is preferable, the RBG size for being its distribution is 10PRBs, then only need instruction 100/10= 10 kinds of resource locations.Therefore, it is the user under the conditions of different communication environment such as different channels according to the embodiments of the present invention Equipment allocated size different RBG and/or PRG, can greatly reduce and be used to refer to opening in the DCI signalings of resource allocation Pin.

S102, indicate respectively that the size is S to first user equipment and the second user equipment₁First money Source block and size are S₂Secondary resource block.
