Description
Technical field
The present invention relates to the relaying technique in the radio communication, relate in particular to a kind of control method and system of uplink speed.
Background technology
Long Term Evolution (the LTE of 3G (Third Generation) Moblie, Long Term Evolution) system, be the third generation affiliate (3GPP of organization planning, Third Generation Partnership Projects) Fa Zhan new wireless communication system based on OFDM (OFDMA, Orthogonal Frequency Division Multiple Access) technology.Compare with the existing wireless communications technology, it is big that LTE has a data transfer bandwidth, the spectrum efficiency height, and advantage such as the anti-interference that the wireless signal multipath is disturbed is good is the major technique of next generation communication system.The LTE system is by the universal land radio access web (E-UTRAN of evolution, Evolved UniversalTerrestrial Radio Access Network), subscriber equipment (UE, User Equipment), the packet-based core networks of evolution (EPC, Evolved Packet Core) are formed.As shown in Figure 1, E-UTRAN is made up of base station (eNB), and eNB connects by X2 interface between the eNB by S1 interface and Mobility Management Entity (MME, Mobility ManagementEntity) and (S-GW, Serving Gateway) connection.On the LTE basis, 3GPP is just continuing to develop senior Long Term Evolution (LTE-Advanced, Long-TermEvolution advance) standard.LTE-A has adopted such as spectrum aggregating (CA, Carrier Aggregation), wireless relay (Relay), and high-order multiple-input and multiple-output technology such as (MIMO, Multiple Input Multiple Output) can realize higher systematic function.
In cordless communication network, landform or environment reason some areas arranged owing to can't be carried out the wired backbone network connection of ordinary base station, perhaps some are covered dead angles or hot zones has provisional wireless coverage demand, but it is higher to set up the base station equipment cost of wired connection.For these wireless coverage demands, can adopt Relay equipment to solve usually.As shown in Figure 2, Relay equipment is connected by wireless signal with the existing network base station, and provides service to the UE in self coverage, thereby realizes coverage extension, reduces covering the dead angle, shifts purposes such as hot zones load.
Wireless relay is one of technology of supporting of LTE-A.In LTE-A, the base station of carrying out wireless connections with via node (RN, Relay Node) is called donor base station (DeNB, Donor eNB), and the Radio Link between DeNB and the RN is called back haul link (backhaul link), and its air interface is called the Un interface.Radio Link between RN and the UE is called access link (access link), and its air interface is called the Uu interface.RN serves as the role of an eNB for the UE of its service, then serves as the role of a UE for its DeNB.Downlink data arrives DeNB earlier, and then passes to RN, and RN transfers to UE again, otherwise then up.
The LTE-A system mainly uses " first kind wireless relay " (Type 1 Relay), and so-called first kind wireless relay is meant the wireless relay nodes that possesses following technical characterictic:
1, for the UE under the via node service, the formed new sub-district of via node is an individual cell, is different from the DeNB sub-district;
2, there is independently physical area identification (PCI, Physical Cell ID) the Relay sub-district, and physical signallings such as the synchronizing signal of broadcasting oneself in the sub-district and reference signal;
3, the UE under the via node service directly receives up-downgoing scheduling and feedback information from via node, also directly sends ascending control information to via node;
4, concerning the UE of LTE version 8 (Rel 8), the eNB sub-district of Relay sub-district and common Rel 8 is as broad as long.
For access link, its air interface should be followed Rel 8 standards.According to Rel 8 standards, UE will distribute according to up priority of logical channels uplink transmission resource according to the regulation of 3GPP TS 36.321 standard 5.4.3.1 joint when carrying out transmitting uplink data between each logic channel.UE is known the uplink transmission resource piece that it is assigned with according to its uplink mandate (Uplink Grant) of receiving on downlink physical control channel (PDCCH, Physical Downlink Control Channel).The concrete distribution as shown in Figure 3, the logic channel of limit priority will at first be distributed to satisfy its prioritized data rate (PBR, Prioritized Bit Rate) resource, the logic channel that is lower priority then is assigned with resource according to its PBR demand successively, and the uplink transmission resource of appointment is distributed fully in Uplink Grant; If still have the residue ascending resource after the PBR resource requirement of satisfying all logic channels, then surplus resources continues just to distribute according to priority of logical channels, and as much as possible satisfies the resource requirement of high priority logic channel.That is to say that if the data volume that generation is sent out in the high priority logic channel has surpassed the surplus resources size, then surplus resources will all be distributed to this logic channel.
This shows, Rel 8 uplink transmission resource distribution methods had both guaranteed the priority demand of Different Logic channel, limit the high priority logic channel by PBR again and take whole resources for a long time, avoid the situation that causes the low priority logical channel data to can not get sending.
In 3GPP TS 36.321 standard 5.4.3.1, define a kind of " token bucket " algorithm and realized above-mentioned resource allocation methods.Each logic channel is provided with a token bucket (Token Bucket), token quantity is designated as Bj in the token bucket, and Bj is initialized as 0, and token adds in bucket with PBR speed as time passes, reaching token bucket full-size (TBS, Token Bucket Size) back Bj no longer continues to increase.In Rel 8, TBS come to determine according to token bucket size duration (BSD, Bucket Size Duration), i.e. TBS=PBR * BSD, and the size of TBS has determined the size of uplink speed.Divide timing when carrying out ascending resource, distribute, thereby guaranteed the PBR resource requirement of each logic channel by priority of logical channels and with reference to the token quantity Bj of respective logical channels token bucket class.In addition, token bucket full-size has limited the impact of the mass data of some logic channel burst to the resource generation.
PBR is two parameters that logic channel is relevant with BSD, gives UE by Radio Resource control (RRC, Radio Resource Control) signaling by eNB (at the Uu interface just by Relay) when setting up up logic channel.ENB (perhaps Relay) decides the concrete numerical value of PBR or BSD parameter according to self internal algorithm.
For the back haul link between Relay and the DeNB, its uplink transmission resource is distributed the Rel 8 defined processes of still following.DeNB will be notified to Relay with parameters such as PBR, BSD by the RRC signaling.
There are mapping relations between the up logic channel on Uu interface and the Un interface.This mapping may be man-to-man, that is to say a up logic channel of the corresponding Un interface of up logic channel of each Uu interface, as shown in Figure 4; Also may be many-to-one, that is to say that the up logic channel that has many Uu interfaces is mapped to the up logic channel of same Un interface according to certain rule (such as according to identical QoS demand), wherein many logic channels of Uu interface may belong to a UE, also may belong to a plurality of UE, as shown in Figure 5.
The PBR of Un interface logic channel and BSD parameter should Uu interface pairing with it the PBR and the BSD parameter of one or more logic channel be complementary.For example, if the up logic channel of certain of Un interface is corresponding to three up logic channels of Uu interface, and the PBR sum of three up logic channels of Uu interface is 50Kbps, and the PBR of the up logic channel of Un interface is set to 20Kbps, and the upstream performance that may cause UE like this is owing to the PBR of the up logic channel of Un interface is provided with too small being affected.
When DeNB when the Un interface is set up up logic channel, and do not know the mapping relations of this up logic channel and the up logic channel of Uu interface and the PBR of the up logic channel of Uu interface that is shone upon and the setting of BSD parameter.Therefore, the aforesaid situation that do not match appears in Uu interface that Relay and DeNB independently make respectively and the setting of Un interface parameters probably, and causes data transmission performance to be affected.
