Abstract
In the LTE cellular communication system (100) polymerizeing with carrier wave, UE (106), which is configured as ignoring scheduling request, forbids timer (107), the scheduling request forbids timer to be arranged to the operation when request is transferred in transmission on one-component carrier wave, and further sends scheduling request on another component carrier before timer (107) expires.This can reduce the average retardation that uplink data packet is sent from UE (106) to evolution node B (101).
Description
Technical field
The embodiment of the present application relates generally to cellular communication system, more particularly in a kind of cellular communication system by user
Scheduled transmission device and method of the equipment to network element.
Background technique
Cellular communication system, such as the third generation (3G) mobile call standard and technology are well-known.This 3G standard
It is developed with technology by third generation partner program.Third generation wireless communication is usually developed, for supporting macrocell
Mobile phone communications.In a relatively large coverage area, this macrocell utilizes high-power base station and channel radio
Letter unit is communicated.In general, wireless communication unit, or usually signified user equipment (UE, User equipment) are logical
Cross radio network sub-system (RNS, Radio Network Subsystem) and 3G wireless communication system core network (CN,
Core Network) communication.Cordless communication network generally includes multiple radio network sub-systems, each radio net subsystem
System includes the cell of one or more user equipment attachment, is thus connected to network.Each macrocell RNS further comprises
With the controller of the form of radio network controller (RNC, Radio Network Controller), and the controller can be grasped
Make ground and is coupled to one or more node B (NodeB).Communication system and network have been directed towards the direction of broadband and mobile system
Development.Third generation partner program has developed long term evolution (LTE, the Long Term for mobile access network
Evolution) solution, i.e. evolved universal mobile communication system terrestrial access network (E-UTRAN, Evolved
Universal Mobile Telecommunication System Territorial Radio Access Network),
And System Architecture Evolution (SAE, System Architecture Evolution) solution party for mobile core network
Case, i.e. evolution block core (EPC, Evolved Packet Core).Macrocell in LTE system is by referred to as evolution node B
It supports the base station of (evolved NodeB is abbreviated as eNodeB or eNB).
Further development, long term evolution advanced (LTE-Advanced) have drawn carrier wave polymerization (CA, Carrier
Aggregation concept) is to increase bandwidth.Each polymerization carrier wave is known as component carrier (CC, Component Carrier).
Each component carrier has the serving cell that can be all supported by single eNB.Main plot (PCell, primary
Cell it) is introduced into the concept of supplementary cell (SCell, secondary cell) for supporting CA.PCell is analogous to non-load
Serving cell under wave polymerizing condition is mainly used for (opposite other function) physical uplink link channel (PUCCH, Physical
Uplink Channel) transmission is connected with wireless heterogeneous networks (RRC, Radio Resource Control) and reconstruction.SCell
PCell or one group of serving cell can be affixed to by RRC connection reconfiguration procedure.
Before UE can send data to eNB, UE first must receive uplink link (UL, Uplink) from eNB and award
Weigh information.In LTE system, using dynamic dispatching (that is, using so-called scheduling request (SR, Scheduling Request)
Process), random access procedure or semi-continuous scheduling (SPS, Semi-Persistent Scheduling) send UL authorization to
UE。
In current LTE system, UE is using so-called SR to send new data for requesting uplink resource
Transmission.In general, eNB is that UE configures SR via radio resource connects (RRC, Radio Resource Connection) signaling
Configuration index, in order to which UE sends scheduling request on PUCCH.Particular schedule request configuration index has specified period and son
Frame offset value.UE uses SR index it is determined that sending the subframe of scheduling request, to determine that transmission the next of scheduling request can
Use chance.In a burst, the total delay of the uplink transmission delay of the first data packet depends on having the number being ready for sending
According to particular UE at receive uplink license speed.The scheduling request period is usually 10ms, and studies have shown that UE SR
The waiting time of chance is about the 30% of entire radio access network delay.It is any further studies have shown that in a burst
The improvement that the delay for transmitting the first uplink data packet can be made reduced all can be to whole TCP/IP (Transmission
Control Protocol, transmission control protocol/Internet Protocol, Internet protocol) handling capacity generate great shadow
It rings.
In order to avoid unnecessary SR is transmitted and reduces the load in PUCCH, scheduling is introduced in Release-9 and is asked
It asks and forbids timer (sr-Prohibit Timer-r9).Sr-Prohibit Timer-r9 information element is located at mac-
Under MainConfig, it can take the value between 0 to 7.The value of sr-ProhibitTimer is usually scheduling request section.0 table
Show the timer that SR transmission is not configured on PUCCH.1 corresponds to a scheduling request section, and 2 correspond to 2 scheduling
Request section, and so on.UE will start the timer after sending SR.When timer operation, it will effectively forbid UE
SR is sent on PUCCH.
(until Release12) in conventional carrier polymerization, only PCell is configured with PUCCH.Therefore, it is realized by SR
UL authorization can only pass through a carrier wave, i.e. PCell.It is had agreed in the polymerization of 13 carrier wave of Release, it should support
The SR in PUCCH on SCell is used with the resource mitigated on PCell.Further, most two cells of a UE are matched
It is equipped with PUCCH.Similarly, it should an only SR process, regardless of whether configuring D-SR (Dedicated in multiple cells
Scheduling Request, specific schedule request), i.e., it is sent on PCell or SCell and sr-ProhibitTimer
When D-SR, only a SR-COUNTER increases.In the case where configuring D-SR resource on the SCell of PCell and PUCCH, sr-
ProhibitTimer should be based on the shorter section SR.
Also reach common understanding, in the case where configuring SR on the PUCCH SCell and PCell of activation, when the first uplink
When link data packet is ready for transmission, medium access control (MAC, Median Access Control) entity of UE refers to
Show that physical channel sends SR when first time, chance occurred, and SR of the UE MAC entity on PUCCH SCell and PCell is in
When identical TTI (Transmission Time Interval, Transmission Time Interval), a SR is selected.Which is selected stay
It is executed to UE.For example, if multiple PUCCH resources of SR are effectively, due to having multiple CC can in the same time for TTI
To be used for SR transmission, leaves UE for and execute to determine which PUCCH resource used.
There is provided it is a kind of in a burst, reducing the delay of the first uplink data packet, and with single sr-
The compatible device of the concept of ProhibitTimer is advantageous.

Specific embodiment
Those of ordinary skill in the art should appreciate that and understand that the details of embodiments described herein is only this Shen
The explanation of section Example please, and introduction set forth herein is suitable for various situations.
Referring now to Fig. 1, the embodiment of LTE cellular communication system operation local in the application is shown, and whole
It is indicated with 100, including enode (eNB, evolved Node) 101.ENB 101 includes scheduler 102 and transceiver 103.
ENB 101 is polymerize using carrier wave and supports the first component carrier (CCx) and second component that are represented respectively by cell 104 and 105
Carrier wave (CCy).In other embodiments, eNB 101 can also support more than two component carriers.Carrier wave polymerize enabled (CA-
Enabled UE 106) is located at simultaneously in the overlay area of two cells 104,105.Transceiver 103 arranges in a conventional manner,
For being transmitted to UE 106 and receiving signal of communication and data from UE 106.UE 106 forbids timing configured with single scheduling request
Device (sr-ProhibitTimer) 107 and transmitter/receiver device 108, for transmitting to eNB 101 and being connect from eNB 101
Receive transmission.
ENB 101 enables and is in the UE (such as UE 106) of connection status to communicate with component carrier, and these UE can be with
Semi-static is configured at least one uplink component carrier.UE can also be on the first component carrier and second component carrier wave
It is configured periodic scheduling request chance, and these component carriers can be made while being activated for service UE.In eNB
In, scheduler 102 can regular monitoring uplink scheduling load and UE activity, and using these information dynamic adjustment at two
SR scheduling parameter between component carrier (CCx and CCy).
When being applied to conventional method only to provide a sr-Prohibit Timer, UE MAC entity indicates PHY the
Scheduling request is sent when chance arrival, and will not consider any subsequent SR chance in sr-ProhibitTimer operation
(including SR chance relevant to another CC).On the contrary, in the embodiment in figure 1, even if in sr-ProhibitTimer operation,
The UE MAC entity of UE 106 considers other scheduling request chances occurred on other component carriers.sr-ProhibitTimer
Information element is used for cell group (that is, being used for all component carriers from single eNB, example in MAC-MainConfig
CCx and CCy as shown in Figure 1).
The present invention can improve some bad situations that above-mentioned conventional method may cause.For example, it is assumed that UE 106 is needed
Every 2ms is wanted to send scheduling request, to meet data delay limitation.Moreover, it is assumed that CCx (can only be limited) since scheduling request loads
Every 4ms provides chance, and CCy can provide chance with every 2ms.If the period of CCx and CCy is all set to 2ms, and sr-
The value of ProhibitTimer is arranged to zero, then the scheduling request load on CCx will be unacceptable.On the other hand,
If the value of sr-ProhibitTimer is arranged to 1, two component carriers of imperfectible intertexture (interleave)
CCx and CCy.By allowing UE to ignore sr-ProhibitTimer, the present invention has avoided these problems.
If UE fails to respond to the scheduling request sent in first, such as the scheduling request on CCx, received from eNB
Scheduling grant, then problem becomes more serious.It is excessively poor or due to scheduling request that this is likely to occur in the covering of CCx uplink
Failure or even due at physical downlink control channel (PDCCH, Physical Downlink Control Channel)
Upper reception uplink grant failure.It that case, UE is by the first time chance after sr-ProhibitTimer expires
When, it attempts to send another SR, thus waste time.Equally, such case is improved through the invention.
Consider another example, wherein the uplink covering on CCx is excessively poor, and CCx has the scheduling request of 1ms
Period, CCy have the period of 5ms, and must be by sr-ProhibitTimer due to the load limitation on the PUCCH of CCx
Value is set as 1.In this example, any scheduling request on CCy may be ignored completely because UE always strive to it is enterprising in CCx
Row (failure) scheduling request.In addition, may arrived dsr-TransMax when the scheduling request chance on CCy is available, lead
Scheduling request process is caused to be cancelled earlier without being an attempt to alternative link.Once again, the present invention can improve these feelings
Condition.
It is the flow chart of the embodiment of the 106 scheduled transmission method of UE in Fig. 1 referring now to Fig. 2, Fig. 2.
At 201, single sr-ProhibitTimer is configured in UE 106.It, must by the transmission of eNB 101 at 202
The configuration signal wanted, the first component carrier CCx (being indicated by the cell 104 in Fig. 1) are configured in UE 106.The configuration according to
Known technology (including such as RRC connection procedure) executes.At 203, according to traditional technology, include by the transmission of eNB 101
The scheduling request of scheduling request configuration information element configures, and the scheduling request configuration of component carrier CCx is configured in UE 106.
Scheduling request configuration is substantially notified to UE by PUCCH that is available on component carrier CCx and being used to be scheduled request
Resource.At 204, necessary configuration signal is sent by eNB 101, second component carrier wave CCy is (by 105 table of cell in Fig. 1
Show) it is configured in UE 106.The configuration is according to known carrier aggregation technology.At 205, according to traditional technology, pass through eNB
101, which send the scheduling request including scheduling request configuration information element, configures, and the scheduling request configuration for component carrier CCy exists
It is configured in UE 106.Scheduling request configuration substantially to UE notice will on second component carrier wave CCy it is available and be used for
It is scheduled the PUCCH resource of request.At 206, UE 106 identifies that the occur on any component carrier first scheduling is asked
Chance is sought, and scheduling request is sent to eNB 101 according to traditional technology.When sending the scheduling request, sr-
ProhibitTimer brings into operation (207).Even before sr-ProhibitTimer expires, UE 106 is in another component
Further scheduling request chance is found on carrier wave.When UE 106 identifies further scheduling request chance at 208, UE
106 can send another scheduling request at 209 on another component carrier.When receiving scheduling authorization from eNB 101, UE
106 can deliver a packet to eNB at 210, then terminate scheduling request process.Only one scheduling request process is in UE
It is run in MAC entity, therefore keeps the compatibility with the process currently defined.In addition, the embodiment of Fig. 2 is also and in the group
Multiple component carriers have single sr-ProhibitTimer protocol-compliant.
The problem of behavior of UE covering (overriding) sr-ProhibitTimer can be selection.For example, postponing
In tolerance application, it is believed that UE and the lesser burden of network application (from accelerating for the scheduling request that must be handled)
The delay time for not being reduction uplink data is more useful.If scheme is deemed appropriate, UE 106 can be with
It independently determines to apply such behavior；Or optionally, eNB 101 (can be transmitted) by RRC configures such row for UE
For.Otherwise, scheduling request operation can be operated as traditional mode.
In one embodiment, it is associated with the service component carrier wave that each scheduling request configures to be arranged to configuration by UE 106
Index, the state of index depends on whether to send scheduling request using component carrier.Referring now to Fig. 3 and Fig. 1
The present embodiment is described.
In UE 106, index be defined to for each scheduling request configure service CC (CCx of example as shown in figure 1 and
CCy).There are three types of possible states for index: " initial ", " covering " and " use ".In " initial " state, sr-
ProhibitTimer is suitable for the CC under conventional situation.In " covering " state, ignore sr- about the CC
ProhibitTimer, to allow to select the CC (as additional carrier) for sending scheduling request, even if sr-
ProhibitTimer is currently running.In the state of " use ", component carrier is used to send scheduling request, and one
Denier has sent scheduling request, and sr-ProhibitTimer begins to run, before specific scheduling request process terminates, index
State cannot be changed.
Therefore, if sr-ProhibitTimer last (again) starts to transmit scheduling request on CCx, it is in office what
The next scheduling request chance occurred at user equipment MAC on his CC (example is CCy as shown in figure 1) can be used, as long as
This CC has not yet been used for transmission since scheduling request program starts.
At 301, once the scheduling request configuration for all service CC is configured in user equipment 106, and SR
Process starts at UE MAC entity, then sets " initial " for each index of each CC.
At 302, on each TTI, user equipment inspection simultaneously determines whether sr-ProhibitTimer is currently running, and
And check have scheduling request chance each CC index with identify its index be currently set as " initial ", " covering " and
The CC of " use " state.
At 303, in UE, one group of " effective " CC is created.Only scheduling request chance is provided simultaneously in the TTI of specific concern
And (i) sr-ProhibitTmer not running/out of date when, or (ii) sr-ProhibitTimer is currently running, but the rope of CC
When drawing in " covering " state (therefore having ignored sr-ProhibitTimer), CC just includes in this set.
At 304, CC can be selected from the effective CC of the group；Also, if sr-TransMax is not yet reached, it will herein
SR is sent on the CC of selection.
Whenever sending SR on CC, sr-ProhibitTimer starts (again) at 305.In addition, at 306, such as
Fruit is not yet in " use " state, then the index of the CC is changed to " use ", and all in " initial " state
The index of other CC, if so, will be changed to " cover ".
In one optionally embodiment, the content in conjunction with described in Fig. 2 and Fig. 3 as above, the eNB 101 in Fig. 1, which is adjusted, to be made
It obtains it and knows the ability that UE 106 ignores sr-ProhibitTimer.The scheduler 102 of eNB101 uses this information to optimization not
Joint with the SR relevant parameter on component carrier configures, in a burst, be further reduced UE 106 and send the first data
The delay time of packet.
For example, it is contemplated that the embodiment of the carrier wave CCx, CCy and CCz of three SR configuration, wherein the SR period of CCx is 1ms,
The SR period of CCy and CCz is 2ms and sr-ProhibitTimer=1 (i.e. 1ms).There are two types of possible configurations；First is that
Chance on CCy replaces with the chance on CCz, second is that (the aligned consistent with each other of the chance on CCy and on CCz
with each other).If scheduler 102 knows that UE can ignore sr-ProhibitTimer, it will determine that first matches
The better configuration being used to is set, because even the first (or even second) SR transmission is broken down, next chance will
Present in the TTI followed closely.
The ability for sending the UE of notice to eNB can be completed in various ways (for example, when UE is initiated, or in the ability
When during the operation that can be dynamically changed, the ability of notice UE is transmitted by RRC or L1 signaling etc.).
In another embodiment, UE MAC entity has for the SR chance generated by different CC, differently handles sr-
The ability of ProhibitTimer.In order to give UE to provide aforementioned capabilities, additional from eNB to UE will be needed to transmit, so as to logical to UE
Know the explanation appropriate for each CC.
