Method 200 starts from 210, here, terminal device 120 is received for the network equipment 110 and end from the network equipment 110 The CSI of channel request (hereinafter also referred to " CSI request ") between end equipment 120, the request indicates the reference for determining CSI Signal resource.In certain embodiments, the reference signal resource is CSI-RS.In further embodiments, this is with reference to letter Number resource can be the RS resources that can be used to estimate any other type of desired signal, such as public reference signal (CRS) resource.
220, the comparison of number and threshold number of the terminal device 120 based on reference signal resource, delay budget is determined. The delay budget indicates position of second subframe relative to the first subframe.Request for CSI is received in the first subframe, CSI will be transmitted in the second subframe to the network equipment 110.
In certain embodiments, determine that delay budget includes：The ratio of number and threshold number based on reference signal resource Compared with one offset of determination；And reference delay budget is increased with the offset, so as to obtaining delay budget.In some implementations In example, determine that offset includes：It is more than threshold number in response to the number of reference signal resource, is increased with the first scheduled volume and offset Amount.
Consider a specific example.In the specific example, terminal device 120 can determine to prolong based on following formula Slow budget：
L=L0+δ (1)
Wherein L represents delay budget, L0Reference delay budget is represented, δ represents offset.
Reference delay budget L0The value of defined in current LTE specification, such as 4 can be taken.Certainly, reference delay budget L0 It is also possible that any other value, which can be taken,.The scope of the present disclosure is not limited in this respect.
For terminal device 120, one or more threshold values of reference signal resource number can be predefined, offset delta can To be determined based on the comparison of the number of reference signal resource and one or more threshold values.As an example, terminal device 120 can determine offset delta based on following formula
Wherein y1..., yMRepresent the M predefined threshold values of reference signal resource number, M for example can 1 to 10 scope It is interior.If the number of reference signal resource is more than ym, then Iym=1, otherwise Iym=0.For example, in the case of M=3, y1、y2With y3Can be respectively 4,6 and 8.If the number of reference signal resource is 8,Now, offset delta=2.
Using embodiment of the disclosure, the comparison of number and threshold number based on reference signal resource is pre- to determine to postpone Calculate.When the number increase for the reference signal resource being configured, identified delay budget also increases.Thus, it is ensured that terminal Equipment has enough processing times to carry out reference signal measurement and calculating.
As it is known, CSI request can be transmitted on down control channel.The example of the down control channel includes But it is not limited to：Physical down control information (PDCCH) and the physical down control information (ePDCCH) of enhancing.Compared to PDCCH, when CSI request is being transmitted on ePDCCH, decoding time of the terminal device 120 to ePDCCH will be longer.Cause This, when terminal device 120 is receiving CSI request on ePDCCH, can be based on following formula further to increase expression Delay budget in formula (2), to ensure that terminal device has enough processing times to carry out reference signal measurement and calculating：
Wherein if CSI request is received on ePDCCH, then IePDCCH=1, otherwise IePDCCH=0.
From expression formula (3), when CSI request is being received on ePDCCH, terminal device 120 can further increase Delay budget, to ensure to have enough processing times to carry out reference signal measurement and calculating.
The comparison of number and threshold number based on reference signal resource is described above with reference to Fig. 2 to determine delay budget Scheme.Because reference signal resource is associated with the set of antenna port, thus can also be based on antenna port number with The comparison of another threshold number determines delay budget.
Embodiment of the disclosure is described more fully below by way of Fig. 3.Fig. 3 is shown according to an aspect of this disclosure Some embodiments communication means 300 flow chart.It is appreciated that method 300 can be by all terminal devices as shown in Figure 1 120 implement.It should be appreciated that method 300 can also include unshowned additional step and/or can omit shown Step, the scope of the present disclosure are not limited in this respect.For discussion purposes, method 300 is said below with reference to Fig. 1 It is bright.
Method 300 starts from 310, here, terminal device 120 is received for the network equipment 110 and end from the network equipment 110 The CSI of channel request (hereinafter also referred to " CSI request "), the request indicate to be used for transmission of reference signals between end equipment 120 Antenna port.
320, the comparison of number of the terminal device 120 based on antenna port and the 3rd threshold number, delay budget is determined. Delay budget indicates position of the 7th subframe relative to the 8th subframe.Reference signal will be in the 7th subframe to the network equipment 110 Transmission, CSI request are received in the 8th subframe.It should be appreciated that a reference signal resource can be with the set of antenna port It is associated.For example, a reference signal resource can be associated with eight antenna ports.Therefore, it is used in method 300 on the same day The 3rd threshold number that the number of line end mouth is compared should be different from being used for the number with reference signal resource in method 200 The first threshold number being compared.
In certain embodiments, determine that delay budget includes：The ratio of number and the 3rd threshold number based on antenna port Compared with one offset of determination；And reference delay budget is increased with offset, so as to obtaining delay budget.
In certain embodiments, determine that offset includes：It is more than the 3rd threshold number in response to the number of antenna port, with 3rd scheduled volume increases offset.
In certain embodiments, determine that offset also includes：Received in response to request on given down control channel, Offset is increased with the 4th scheduled volume, the 4th scheduled volume and the 3rd scheduled volume are identical or different.
In certain embodiments, receiving request includes receiving the request for aperiodicity CSI.
It should be appreciated that being equally applicable to method 300 above with reference to each feature described by Fig. 2, thus will not be described in great detail.
Current LTE specification regulation, multiple CSI processes can be configured for terminal device, the plurality of CSI processes can be by One CSI request triggering.In addition, current LTE specification (such as LTE Release 13) also specify when multiple CSI requests it Between exist conflict when abandon CSI processes rule.Specifically, current LTE specification defines what terminal device can be supported Maximum CSI number of processes is (by NxTo represent).If terminal device needs the number of CSI processes to be processed to surpass in a single sub-frame Cross the maximum CSI number of processes Nx(continually sent mainly due to the network equipment in the interval of multiple subframes to terminal device CSI request and cause), then terminal device should abandon associated with the CSI request of the newest reception CSI with high index Process.In the case of using aperiodicity CSI-RS, this simple rule that abandons can make the discarding of CSI processes more frequent Generation.
In order to solve the above problems at least in part, embodiment of the disclosure proposes, as CSI indicated in CSI request When the number of process is more than the number of available CSI processes, part CSI processes are abandoned based on the type of CSI processes, so that The discarding operation of CSI processes is more reasonable.
Embodiment of the disclosure is described more fully below by way of Fig. 4.Fig. 4 is shown according to an aspect of this disclosure Some embodiments communication means 400 flow chart.It is appreciated that method 400 can be by all terminal devices as shown in Figure 1 120 implement.It should be appreciated that method 400 can also include unshowned additional step and/or can omit shown Step, the scope of the present disclosure are not limited in this respect.For discussion purposes, method 400 is said below with reference to Fig. 1 It is bright.
Method 400 starts from 410, here, terminal device 120 is received for the network equipment 110 and end from the network equipment 110 The CSI of channel request between end equipment 120, the request indicate the CSI process group associated with the CSI.
420, it is more than the number of available CSI processes in response to the number of the CSI processes in CSI processes group, based on CSI The type of process abandons at least a portion CSI processes in CSI processes group.
In certain embodiments, the type of CSI processes is to be configured with the process of aperiodicity reference signal or be configured There is the process of periodic reference signal.
In certain embodiments, the CSI processes for being configured with aperiodicity reference signal are endowed higher processing priority. In other words, in the case that the number of the CSI processes in CSI processes group is more than the number of available CSI processes, quilt is preferentially retained It is configured with the process of aperiodicity reference signal.
Specifically, it is assumed that CSI processes group includes NA-CSI-RSThe individual process for being configured with aperiodicity reference signal and NP-CSI-RSThe individual process for being configured with periodic reference signal, and the maximum CSI number of processes that terminal device can be supported It is expressed as Nx, do not complete the number of CSI processes reported and be expressed as Nu.In other words, only it is configured with aperiodicity reference signal Process in N1=min { NA-CSI-RS, max { Nx-Nu, 0 } } individual process and it is configured with the process of periodic reference signal N2=min { NP-CSI-RS, max { Nx-Nu-N1, 0 } } individual process is retained to be handled.
Because the process for being configured with aperiodicity reference signal is triggered as required, according to the reality of the disclosure Apply example and may insure that these processes have higher processing priority compared to the process for being configured with periodic reference signal, from And it can be handled with low latency.
In addition to aperiodicity CSI-RS as discussed above, current LTE specification (such as LTE Release 14) Also support in CSI feedback framework using mixing CSI-RS transmission.This CSI feedback framework is generally all the multistage CSI of structure Feedback, wherein first order CSI feedback is that terminal device measures the first kind CSI-RS from the network equipment and obtained on full bandwidth Arrive, second level CSI feedback is that terminal device is obtained by measuring the second class CSI-RS generated according to first order CSI feedback 's.
Especially, broadband precoding matrix instruction (PMI) letter is included in first order CSI feedback and second level CSI feedback Breath, and first order CSI feedback and second level CSI feedback are carried out on ascending control channel.When progress first order CSI feedback When exceeding available uplink control channel resource (such as PUCCH resource) with the resource needed for the CSI feedback of the second level, the first order Partial feedback information in CSI feedback and second level CSI feedback will be unable to transmit on ascending control channel.
In order to solve the above problems at least in part, embodiment of the disclosure proposes to believe the PMI in first order CSI feedback Breath assigns higher priority, to ensure to generate the second class CSI-RS that will be used in the CSI feedback of the second level.
Embodiment of the disclosure is described more fully below by way of Fig. 5.Fig. 5 is shown according to an aspect of this disclosure Some embodiments communication means 500 flow chart.It is appreciated that method 500 can be by all terminal devices as shown in Figure 1 120 implement.It should be appreciated that method 500 can also include unshowned additional step and/or can omit shown Step, the scope of the present disclosure are not limited in this respect.For discussion purposes, method 500 is said below with reference to Fig. 1 It is bright.
Method 500 starts from 510, here, terminal device 120 is associated with single CSI processes from the reception of the network equipment 110 First kind reference signal and the second different class reference signals, the second class reference signal be based on it is related to first kind reference signal The CSI of connection and generate.
