In 2 the case where.
On the one hand, in the case that m is equal to 1, SRS resource collection is transmitted in 1 time slot of time slot n+k to time slot n+k+1-1
SRS resource in conjunction transmits the SRS resource in SRS resource set that is, in time slot n+k；In such cases, terminal is only in time slot
Part SRS resource in n+k in transmission SRS resource set, remaining SRS resource that terminal will not transmitted in SRS resource set.
Specifically, step 102 includes:
Obtain the quantity A for the SRS resource that can at most transmit in time slot n+k, wherein A is the integer more than or equal to 1；
The quantity for the SRS resource that can at most transmit in time slot n+k is to determine that time slot format can be by net by time slot format and network side configuration
Network equipment first passes through high-level signaling or dedicated signaling (for example, radio resource control RRC signaling) configuration in advance.
It is transmitted in time slot n+k and B SRS in the associated SRS resource set of the aperiodic SRS triggering state of the target
Resource, wherein B is the integer more than or equal to 1, and B is less than or equal to A, and B is less than or equal to the SRS resource collection
The quantity of SRS resource in conjunction.
In this step, for in the associated SRS resource set of the aperiodic SRS triggering state of target in addition in time slot n+k
Remaining SRS resource except B SRS resource of interior transmission, terminal provide remaining SRS not transmitted in the SRS resource set
Source.
Preferably, when the number with the SRS resource in the associated SRS resource set of the aperiodic SRS triggering state of the target
When amount is greater than A, B is equal to A.For example, include 6 SRS resources with the associated SRS resource set of the aperiodic SRS triggering state of target,
The quantity A for the SRS resource that can at most transmit in time slot n+k is 3, then transmission and the aperiodic SRS triggering shape of target in time slot n+k
3 SRS resources (i.e. B is equal to 3) in the associated SRS resource set of state.
Example one
As illustrated in fig. 2, it is assumed that high-level signaling configures the corresponding SRS resource set 0 of aperiodic SRS triggering state 0, SRS resource
It include SRS resource 0-3 in set 0, the offset that aperiodic SRS sends instruction is 4.Terminal device receives downlink in time slot n
The aperiodic SRS triggering state 0 for controlling information triggering is sent, then terminal will start to send SRS resource set 0 in time slot n+4.By
It is influenced in by time slot format and network side configuration, 2 SRS resources at most can be transmitted in time slot n+k, therefore, in n+4 time slot
SRS resource 0 and SRS resource 2 are transmitted, and SRS resource 1 and SRS resource 3 will be transmitted no longer.
On the other hand, in the case that m is more than or equal to 2, in such cases, terminal is in time slot n+k to time slot n+k+m-1
Whole SRS resources or part SRS resource in interior transmission SRS resource set.
Specifically, step 102 includes:
Obtain the quantity for the SRS resource that time slot n+k can at most be transmitted in each time slot into time slot n+k+m-1；When above-mentioned
The quantity for the SRS resource that gap n+k can at most be transmitted in each time slot into time slot n+k+m-1 is configured by time slot format and network side
It determines, time slot format can be first passed through in advance high-level signaling or dedicated signaling (for example, radio resource control RRC signaling) by the network equipment
Configuration.
It is successively transmitted and the aperiodic associated SRS of SRS triggering state of the target in time slot n+k to time slot n+k+m-1
SRS resource in resource collection；Wherein, the quantity for the SRS resource transmitted in each time slot is less than or equal in the time slot
The quantity for the SRS resource that can at most transmit, and the quantity for the SRS resource transmitted in each time slot is less than or equal to the SRS
The quantity of SRS resource in resource collection.
In the above embodiment of the present invention, terminal device and the undesirable network equipments configuration of the network equipment are arbitrarily transmitted
The time-domain resource of SRS resource clashes, therefore assuming that the time-domain resource of any SRS resource does not clash,
It is equal in the sum for the SRS resource that above-mentioned time slot n+k is transmitted into time slot n+k+m-1 and is closed with the aperiodic SRS triggering state of target
The quantity of SRS resource in the SRS resource set of connection.For example, with the associated SRS resource set of the aperiodic SRS triggering state of target
Comprising 6 SRS resources, then the above-mentioned time slot n+k SRS resource transmitted into time slot n+k+m-1 sum also be 6, and this when
The quantity for the SRS resource that gap n+k is transmitted on each time slot into time slot n+k+m-1 is determined by time slot format and network side configuration.
Preferably, the quantity for the SRS resource transmitted in time slot n+k to any two time slot between time slot n+k+m-1
Identical, i.e., the quantity for the SRS resource transmitted in each time slot is identical.Time slot can be determined according to time slot format and network side configuration
The quantity for the SRS resource that can at most transmit in n+k to each time slot between time slot n+k+m-1 is identical.This kind of mode is each
The quantity for the SRS resource transmitted in time slot is identical, can simplify base station implementation complexity.Under such mode, time slot n+k to time slot n+
Each time slot between k+m-1 is used to transmission SRS resource.
Example two (m is equal to 2):
As shown in Figure 3, it is assumed that high-level signaling configures the corresponding SRS resource set 0 of aperiodic SRS triggering state 0, SRS resource
It include SRS resource 0-3 in set 0, the offset that aperiodic SRS sends instruction is 4.Terminal device receives downlink in time slot n
The aperiodic SRS triggering state 0 for controlling information triggering is sent, then terminal will start to send SRS resource set 0 in time slot n+4.By
It is influenced in by time slot configuration, 2 SRS resources, therefore, the prioritised transmission SRS in n+4 time slot at most can be transmitted in a time slot
Resource 0 and SRS resource 2, and SRS resource 1 and SRS resource 3 are transmitted in time slot n+5.
Although the SRS resource for transmitting identical quantity in each time slot can simplify base station implementation complexity, it is also right
The configuration of time slot format is restricted, reduces the flexibility of time slot configuration.Preferably, the embodiment of the present invention also provides another realization
The quantity of mode, the SRS resource transmitted in time slot n+k at least two time slots between time slot n+k+m-1 is different, i.e., multiple
The quantity for the SRS resource transmitted in time slot is different.Time slot n+k can be determined to time slot n+ according to time slot format and network side configuration
The quantity for the SRS resource that can at most transmit in each time slot between k+m-1 is different.Due to the SRS transmitted in multiple time slots
Resource quantity is different, can support the configuration of Flexible timeslot format, is suitable for more scenes.Under such mode, can time slot n+k extremely
SRS resource is transmitted in partial time slot between time slot n+k+m-1, and (i.e. there are one or more between time slot n+k+m-1 by time slot n+k
A time slot is configured as being not used in transmission SRS resource or SRS resource transmission is not configured).
Example three (m is equal to 3):
It is assumed that high-level signaling configures the corresponding SRS resource set 0 of aperiodic SRS triggering state 0, SRS resource
It include SRS resource 0-3 in set 0, the offset that aperiodic SRS sends instruction is 4.Terminal receives downlink control in time slot n
The aperiodic SRS triggering state 0 of information triggering is sent, then terminal will start to send SRS resource set 0 in time slot n+4.Due to by
It is influenced to time slot format and network side configuration, 3 SRS resources at most can be transmitted in n+4 time slot, SRS money is not configured in n+5 time slot
1 SRS resource, therefore, the prioritised transmission SRS resource 0,1 and 2 in n+4 time slot, in n+6 at most can be transmitted in source, n+6 time slot
SRS resource 3 is transmitted in gap.
Further, in the above embodiment of the present invention, it is described in time slot n+k to time slot n+k+m-1 successively transmission with
SRS resource in the associated SRS resource set of the aperiodic SRS triggering state of target, comprising:
In time slot n+k to time slot n+k+m-1, according to the SRS resource sequence in the preconfigured SRS resource set
Successively transmit the SRS resource in the SRS resource set.
In this step, which can be the network equipment and is configured by high-level signaling or dedicated signaling, be also possible to
It makes an appointment in the protocol.SRS resource sequential network equipment and terminal device in the preconfigured SRS resource set is equal
Know in advance, then avoid the problem that the network equipment and terminal device understand differently and cause, promotes SRS transmission efficiency.
Alternatively, in time slot n+k to time slot n+k+m-1, successively according to the SRS resource number in the SRS resource set
Transmit the SRS resource in the SRS resource set.
Specifically, according to the SRS resource sequence of number from big to small or sequence from small to large in SRS resource set
Or odd even sequence etc. successively transmits the SRS resource in SRS resource set.It should be noted that the transmission of SRS resource number
Sequential network equipment and terminal device are also to know in advance, and the cause that can understand differently to avoid the network equipment and terminal device is asked
Topic promotes SRS transmission efficiency.
Example in undertaking, although the undesirable network equipments configuration of terminal device and the network equipment arbitrarily transmits SRS resource
Time-domain resource clashes, but actual transmissions during still may there is a situation where resource contentions, specifically, in time slot
There are the associated SRS moneys of aperiodic SRS triggering state different from least two into the target time slot between time slot n+k+m-1 in n+k
The transmission of source set, and the time domain of different SRS resource set occupies in the case that symbol clashes, the embodiment of the present invention mentions
The contention-resolution schemes of supply include:
Obtain at least two SRS resource set clashed；
The time of reception that instruction is sent according to the aperiodic SRS at least two SRS resource set for sending conflict, from generation
A target SRS resource is selected to be integrated into transmission in the target time slot at least two SRS resource set of conflict.
In this step, the transmission with the associated SRS resource set of aperiodic SRS triggering state is referred to by aperiodic SRS transmission
Show triggering, therefore the time of reception of aperiodic SRS transmission instruction is equivalent to the triggering moment of its corresponding SRS resource set.Letter speech
It is provided when the time domain of at least two SRS resource set, which occupies symbol, to be clashed according at least two SRS clashed
The triggering moment of source set is transmitted in at least two SRS resource set clashed to determine in the target time slot clashed
One SRS resource set (target SRS resource set)；For example, transmitting the SRS resource collection of triggering moment earlier above in target time slot
It closes, alternatively, the SRS resource set after transmitting triggering moment in target time slot relatively.
Preferably, frequently clashing in order to avoid the time domain of aperiodic SRS resource occupies symbol, of the invention is above-mentioned
In embodiment, the aperiodic SRS according at least two SRS resource set for sending conflict sends the time of reception of instruction, from
A target SRS resource is selected to be integrated into transmission in the target time slot at least two SRS resource set clashed, comprising:
The aperiodic SRS for obtaining at least two SRS resource set clashed sends each time of reception and the mesh of instruction
Mark at least two time interval value between time slot:
A minimum interval value, the determining and minimum interval are selected from least two time interval value
It is worth corresponding SRS resource collection and is combined into the target SRS resource set；
The SRS resource of the target SRS resource set is transmitted in the target time slot.
In the above embodiment of the present invention, portion can both be guaranteed by preferentially sending the aperiodic SRS resource set triggered more afterwards
Divide the timeliness of aperiodic SRS resource set, frequent collisions can also be generated to avoid aperiodic SRS resource, improve the transmission of SRS
Efficiency.
Further, in the above embodiment of the present invention, for being triggered in at least two SRS resource set clashed
The SRS resource set of moment earlier above provides two kinds of processing modes:
Mode one: stop other in the SRS resource set that transmission clashes in addition to the target SRS resource set
SRS resource set；The aperiodic SRS resource triggered earlier above clashed will stop transmitting.
Which stops the aperiodic SRS triggered earlier above money by preferentially sending the aperiodic SRS resource triggered more afterwards
Source can avoid aperiodic SRS and send generation frequent collisions.
Example four
As shown in fig. 5, it is assumed that high-level signaling configures the corresponding SRS resource set 0 of aperiodic SRS triggering state 0, SRS resource
It include SRS resource 0-3 in set 0, the offset that aperiodic SRS sends instruction is 4；The corresponding SRS of aperiodic SRS triggering state 1
Resource collection 1 includes SRS resource 4 and 5 in SRS resource set 1, and the offset that aperiodic SRS sends instruction is 4.
Terminal is sent in the aperiodic SRS triggering state 0 that time slot n receives Downlink Control Information triggering, then terminal will be
Time slot n+4 starts to send SRS resource set 0.Terminal receives the aperiodic SRS touching of Downlink Control Information triggering in time slot n+1
Hair-like state 1 is sent, then terminal will start to send SRS resource set 1 in time slot n+5.Due to being matched by time slot format and network side
Influence is set, 2 SRS resources, therefore, the prioritised transmission SRS resource 0 and 2 in n+4 time slot at most can be transmitted in a time slot.In n
In+5 time slots, the time domain of SRS resource set 0 and the corresponding SRS resource of SRS resource set 1 occupies symbol and clashes, and terminal will
The SRS resource in the SRS resource set 1 triggered more afterwards is only sent, and stops the corresponding SRS of SRS resource set 0 triggered earlier above
Resource 1 and 3 is sent.
Mode two: in target time slot, stop in the SRS resource set that transmission clashes except the target SRS resource
The SRS resource of other SRS resource set except set.Stop that transmission clashes i.e. in target time slot triggers earlier above
Part SRS resource in SRS resource set.Which, which also indicates the time slot after target time slot and can continue transmission, to be clashed
The SRS resource set triggered earlier above in remaining SRS resource.
Which continues the aperiodic SRS triggered earlier above money by preferentially sending the aperiodic SRS resource triggered more afterwards
Source can avoid aperiodic SRS and abandon, and improve SRS transmission efficiency, and then promote BTS channel state information acquisition performance.
Example five
As shown in Figure 6, it is assumed that high-level signaling configures the corresponding SRS resource set 0 of aperiodic SRS triggering state 0, SRS resource
It include SRS resource 0-3 in set 0, the offset that aperiodic SRS sends instruction is 4；The corresponding SRS of aperiodic SRS triggering state 1
Resource collection 1 includes SRS resource 4 and 5 in SRS resource set 1, and the offset that aperiodic SRS sends instruction is 4.
Terminal is sent in the aperiodic SRS triggering state 0 that time slot n receives Downlink Control Information triggering, then terminal will be
Time slot n+4 starts to send SRS resource set 0.Terminal receives the aperiodic SRS touching of Downlink Control Information triggering in time slot n+1
Hair-like state 1 is sent, then terminal will start to send SRS resource set 1 in time slot n+5.Due to being matched by time slot format and network side
Influence is set, 2 SRS resources, therefore, the prioritised transmission SRS resource 0 and 2 in n+4 time slot at most can be transmitted in a time slot.In n
In+5 time slots, the time domain of SRS resource set 0 and the corresponding SRS resource of SRS resource set 1 occupies symbol and clashes, and terminal will
Only send the SRS resource in the SRS resource set 1 triggered more afterwards.And the SRS resource 1 and 3 of SRS resource set 0 will be in n+6
Gap continues to send.
It should be noted that " the transmission SRS resource " that refers in the embodiment of the present invention refers specifically to " sending SRS resource "；
For example, stopping other SRS resource collection in the SRS resource set that transmission clashes in addition to the target SRS resource set
