Description

A kind of processing method of resource contention and equipment
Technical field
The present invention relates to wireless communication field, particularly a kind of processing method of resource contention and equipment.
Background technology
Present LTE (Long Term Evolution, Long Term Evolution) be to adopt the mode of high-level signaling to notify UE (User Equipment in, subscriber equipment) MBSFN (MBSFN MulticastBroadcast Single Frequency Network, the Multicast Broadcast Single Frequency Network) subframe of system's use.
36.331 the ASN.1 to MBSFN among the v8.5.0 (Abstract Syntax Notation One, ASN 1) describes as follows:
MBSFN-SubframeConfig::＝ SEQUENCE{
radioframeAllocationPeriod ENUMERATED{n?1，n2，n4，n8，n16，
n32}，
radioframeAllocationOffset INTEGER(0..7)，
subframeAllocation CHOICE{
oneFrame BIT?STRING(SIZE(6))，
fourFrames BIT?STRING(SIZE(24))
}
MBSFN is divided into two ranks: Radio Frame (radio frames) and Sub Frame (subframe).
1)Radio?Frame。
Radio frames distributes the mode of employing Period (cycle) and offset (skew) to represent, the MBSFN radio frames will appear in the position of satisfying following formula at SFN (system frame number, System Frame Number):
SFN mod radioFrameAllocationPeriod=radioFrameAllocationOffset (the SFN mould radio frames assignment cycle equals radio frames assignment skew)
2)Sub?Frame
What sub-frame allocation was followed is bitmap (bit mapping) mode, has two kinds specifically:
(1) single radio frames bitmap
OneFrame BIT STRING (SIZE (6)) (a framing bit string (big or small 6 bits))
(2) continuous four radio frames bitmap
FourFrames BIT STRING (SIZE (24)) (four framing bit strings (big or small 24 bits))
For FDD (Frequency division duplex, Frequency Division Duplexing (FDD)), MBSFN subframe available in each radio frames is: #1, #2, #3, #6, #7, #8, and corresponding to 6 bits of bitmap.
For TDD (Time Division Duplex, time division duplex), MBSFN subframe available in each radio frames is: #3, #4, #7, #8, #9, corresponding to preceding 5 bits of bitmap, last 1 bit of bitmap does not use.It should be noted that for TDD sub-frame of uplink can not be assigned to the MBSFN subframe.
When subframe is assigned as four continuous radio frames bitmap, according to 1) in radio frames distribute SFN that formula calculates original position for these four radio frames.At this moment the assignment period of MBSFN subframe is 40ms, and the assignment period of MBSFN subframe all is the integral multiple of 10ms under remaining situation.Be to be 10ms, 20ms, 40ms, 80ms, 160ms, 32ms in the cycle.
Fig. 1 is a MBSFN sub-frame allocation schematic diagram, and as shown in the figure, the assignment period of radio frames is 20ms during the MBSFN sub-frame allocation, and subframe is 1,3,7,8 subframes.
SPS (semi-persistent schedule, semi-continuous scheduling) then, adopts the mode of PDCCH (physical downlink control channel, Physical Downlink Control Channel) resource allocation and activation to transmit by the cycle of system configuration SPS.Be the ASN.1 among 36.331 v8.5.0 below to descending SPS configuration:
SPS-ConfigDL::＝ CHOICE{
release NULL，
setup SEQUENCE{
semiPersistSchedIntervalDL EUMERATED{
sf10，sf20，sf32，sf40，sf64，sf80，
sf128，sf160，sf320，sf640，spare6，
spare5，spare4，spare3，spare2，
spare1}，
numberOfConfSPS-Processes INTEGER(1..8)，
n1-PUCCH-AN-PersistentList
N1-PUCCH-AN-PersistentList，
...
}
SemiPersistSchedIntervalDL represents the cycle of descending SPS, numberOfConfSPS-Processes represents to keep for HARQ (the Hybrid Automatic RepeatRequest of SPS, mixed automatic repeat request) process number, n1-PUCCH-AN-PersistentList represent to keep for ACK (affirmation) the feedback resources index of SPS transmission.
The cycle of SPS is 10ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, 160ms, 320ms, 640ms as can be seen from this parameter of semiPersistSchedIntervalDL.
Fig. 2 is that descending SPS uses schematic diagram, and the example of a descending SPS use as shown is:
It is 32ms that system gives its SPS cycle by RRC (Radio Resource Control, Radio Resource control) signaling UE network configuration.And activate the use of UESPS in the subframe 3 of radio frames 1, and distribute the SPS resource of UE use by PDCCH.Then receive the SPS data on the resource that UE is will be in the subframe behind each 32ms identical.
SPS is that LTE is in order to support the semi-continuous scheduling of the relative and dynamic dispatching that business such as VOIP (Voice over IP, IP-based voice transfer) are introduced.Can be introduced at the R9 of LTE stage MBMS, LTE can adopt proprietary MBSFN subframe to send the MBMS business, and SPS also can dispose relatively more fixing resource for a user.The deficiencies in the prior art are: under certain configuration, will produce resource that sends the MBSFN subframe and the afoul problem of resource that sends the SPS data.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
The inventor notices in the invention process: by Fig. 1 and Fig. 2 as can be known, from the resource allocation that sends the MBSFN subframe as can be seen, the assignment period of MBSFN subframe or be the multiple of 10ms or be the 40ms cycle.And there is the cycle of 32ms, 64ms, 320ms, 640ms in the cycle that sends the SPS data, and these cycles can not divide exactly with the assignment period of MBSFN, therefore, conflict inevitably can occur when MBSFN and SPS dispose simultaneously.
Fig. 3 is a SPS resource and MBSFN subframe conflict schematic diagram, an example that embodies the prior art deficiency as shown in the figure:
The MBSFN sub-frame allocation as shown in Figure 1, the SPS resource allocation as shown in Figure 2, the subframe 7 in radio frames 7 exists SPS resource and the conflict of MBSFN subframe like this.
Based on this, provided the solution when the resource that sends MBSFN subframe and transmission SPS data clashes in the embodiment of the invention, so that the user both can receive the SPS business easily, can receive the MBMS business again.
Fig. 4 is the processing method implementing procedure schematic diagram of resource contention, as shown in the figure, can comprise the steps:
The transmission resource of step 401, the transmission resource of determining the MBSFN subframe and SPS data clashes;
Step 402, base station cancellation send the SPS data on the resource that clashes;
Step 403, UE cancellation receive the SPS data on the resource that clashes.
In the enforcement, the transmission of cancellation SPS data when clashing.In suc scheme the base station at first to judge send the MBSFN subframe resource whether with the resource contention that sends the SPS data, if conflict then cancel the SPS data and send.
UE then judge send the MBSFN subframe resource whether with the resource contention that sends the SPS data, if conflict then cancel the reception of SPS data.
Further, in the enforcement,, can receive the MBMS business in this subframe if UE need receive the MBMS business in this subframe; That is, UE receives the MBSFN subframe on the resource location that clashes.
In the enforcement, base station, UE can be in the following way when judging whether to clash:
Activate time and the resource that the SPS data send according to PDCCH, and the transmission cycle of SPS data, determine to send the resource location of SPS data at the PRB of the subframe of radio frames (physical resource block, Physical Resource Block) on, and, according to the pattern of MBSFN configuration, the resource location of transmission MBSFN subframe also when the subframe of radio frames, is determined the transmission resource contention of the transmission resource and the SPS data of MBSFN subframe.
Embodiment one
Illustrate with specific embodiment below.In concrete the enforcement will be that example describes with collision scenario shown in Figure 3.Activate time and the resource that the SPS data send according to PDCCH, and the cycle of SPS, SPS the subframe 7 of radio frames 75,6, have resource on the 7PRB, and according to the pattern of MBSFN configuration, the MBSFN subframe also occurs in the subframe 7 of radio frames 7.Then send the resource contention of the resource and the transmission MBSFN subframe of SPS data, at this moment cancel the transmission of SPS data, UE also stop at radio frames 7 subframe 75,6, the last reception of 7PRB SPS resource, if UE need receive the MBMS business then still continuing to receive the MBMS business on this subframe on this subframe.
After step 402,403, can further include in the enforcement:
The base station sends the SPS data on the descending sub frame of determining according to preset rules after sending the SPS data on the resource that cancellation is clashing;
UE receives the SPS data on the descending sub frame of determining according to preset rules after receiving the SPS data on the resource that cancellation is clashing.
In the enforcement, when conflict, cancel the SPS data and sent, then can on the follow-up descending sub frame that can send the SPS data that does not conflict, transmit the SPS data.
The SPS transmission has been cancelled in the base station after judging resource that sends the MBSFN subframe and the resource contention that sends the SPS data in suc scheme; Determine to send the descending sub frame of SPS data then according to certain rule, and send the SPS data by this descending sub frame.
Concrete, for example preset rules can be decided to be: determine on the nearest descending sub frame of transmitting time, to send.This is in order to receive the SPS data as early as possible, therefore can to send the SPS data by default rule on nearest, that do not conflict, as can to send SPS data descending sub frame.
Be meant that recently transmitting time is nearest, such as: the conflict subframe is a subframe 2, and subframe 3 be that sub-frame of uplink, subframe 4, subframe 5 is descending sub frame.So nearest subframe is a subframe 4 just, and is nearest after this subframe that refers to recently conflict certainly.If subframe 3 also is a descending sub frame, subframe should be subframe 3 so recently.
UE also when judging resource that sends the MBSFN subframe and the resource contention that sends the SPS data, having cancelled after receiving the SPS data on the conflict subframe, according to prior pre-defined rule, receives the SPS data on the descending sub frame of correspondence.Certainly, if need receiving the MBMS business in the conflict subframe, UE also receives the MBMS business in the conflict subframe.
Embodiment two
Illustrate with specific embodiment below.With collision scenario shown in Figure 3 is that example describes.Activate time and the resource that the SPS data send according to PDCCH, and the cycle of SPS, SPS the subframe 7 of radio frames 75,6, have resource on the 7PRB, and according to the pattern of MBSFN configuration, the MBSFN subframe also occurs in the subframe 7 of radio frames 7.Then send the resource contention of the resource and the transmission MBSFN subframe of SPS data, at this moment cancel the SPS data the subframe 7 of radio frames 75,6, send on the 7PRB, judge that subframe 9 is nearest, that do not conflict, as can to send SPS data descending sub frame, then subframe 95,6, send the SPS data that are cancelled transmission on the 7PRB.
UE also stop at radio frames 7 subframe 75,6, the last reception of 7PRB SPS data, and the subframe 9 of radio frames 75,6, receive the SPS data on the 7PRB, if UE need receive the MBMS business receiving the MBMS business on the conflict subframe then still continue on the conflict subframe.
After step 402,403, can further include in the enforcement:
The base station sends the SPS data on predetermined resource location after sending the SPS data on the resource that cancellation is clashing, the described information of resource location that pre-determines is by signaling indication UE;
UE receives the SPS data on predetermined resource location after receiving the SPS data on the resource that cancellation is clashing, described predetermined resource location is determined according to the indication of described signaling.
In the enforcement, the transmission of cancellation SPS data when conflict, but certain running time-frequency resource can be indicated by signaling in the base station, and will be in this transmitted over resources SPS data.
If the base station at first wants the resource of signaling notice transmission MBSFN subframe and the resource of transmission SPS data to clash in suc scheme, then need on that follow-up resource or those resources, send the SPS data of this cancellation.
Then, when the base station is judged the resource that sends the MBSFN subframe and the resource that sends the SPS data and clashed, after the transmission of cancellation SPS data, on the resource of signaling indication, send the SPS data.The scope of high-rise indication can be a descending sub frame, also can be several descending sub frames.
UE then is after judging resource that sends the MBSFN subframe and the resource contention that sends the SPS data, if because of conflict has been cancelled on the conflict subframe the reception of SPS data, so just determine descending sub frame, and on this subframe, receive the SPS data by the signaling indicating range.If need receiving the MBMS business in the conflict subframe, UE also need receive the MBMS business in the conflict subframe.
Embodiment three
Illustrate with specific embodiment below.
At first, if the base station sends the resource of MBSFN subframe by signaling UE and the resource of transmission SPS data clashes, then the SPS data will send in follow-up 2 to 3 subframes.
The collision scenario that with Fig. 3 is example is that example describes, activate time and the resource that the SPS data send according to PDCCH, and the cycle of SPS, SPS the subframe 7 of radio frames 75,6, have resource on the 7PRB, and according to the pattern of MBSFN configuration, the MBSFN subframe also occurs in the subframe 7 of radio frames 7.Then send the resource of SPS data and send the resource contention of MBSFN subframe, at this moment cancel the SPS data the subframe 7 of radio frames 75,6, send on the 7PRB, and the subframe 0 of radio frames 85,6, send the SPS data that are cancelled on the 7PRB.
UE also stop at radio frames 7 subframe 75,6, the last reception of 7PRB SPS data, and on the subframe 0 of the subframe 9 of radio frames 7 and radio frames 8, detecting the SPS business of whether depositing.UE will detect in the subframe 0 of radio frames 8 and have the SPS business, receive the SPS data then in the position of correspondence, if UE need receive the MBMS business receiving the MBMS business on the conflict subframe then still continue on the conflict subframe.
