Referring to fig. 2, fig. 2 is a method for sending an uplink probe to a UE according to an embodiment of the present invention, where the method is executed in a communication system shown in fig. 1, and the method includes, but is not limited to the following steps:

step S200: the UE transmits SRS on different multiple transmission particles of the same symbol (symbol).

Specifically, in an alternative embodiment, the symbols include, but are not limited to: orthogonal Frequency Division Multiplexing (OFDM) symbols, and the like.

Step S201: the base station schedules the UE to send a denser SRS on a certain transmission granule.

Specifically, in an optional embodiment, the scheduling, by the base station, the UE to transmit the denser SRS at a certain transmission granularity by the base station may include: the SRS transmission may occupy the entire transmission grain bandwidth or a portion of the transmission grain bandwidth.

In an alternative scheme, the transmission granule may be a subband (subband) or a Physical Resource Block (PRB). The subband may be a bandwidth composed of several consecutive PRBs.

According to the technical scheme, the UE transmits the SRS on a plurality of different transmission granularities of the same symbol, and then the base station schedules the UE to transmit the denser SRS on a certain transmission granule, so that the SRS is partially detected, and the utilization rate of network resources is improved.

In the method depicted in fig. 2, in an alternative arrangement,

the SRS on the plurality of transmission particles belong to the same SRS resource; parameters of the SRS resources

And adjusting according to the serial number of the transmission particles or the number of the transmission particles.

In particular, in an alternative arrangement,

the subband # may represent a subband number or a total subband number.

Specifically, in another alternative, taking PRB as an example,

here, the PRB # may represent a PRB number or a PRB number.

In the method depicted in fig. 2, in another alternative,

the SRS on the plurality of transmission particles belong to a plurality of different SRS resources, and the SRS on each transmission particle belongs to one SRS resource.

Optionally, if the SRS is configured as a periodic or semi-persistent SRS, the period of all SRS resources within one SRS resource set is the same and the offset is the same.

Optionally, if the SRS is aperiodic, the time domain starting positions of all SRS resources within one SRS resource set are the same. Or, all SRS resources in one SRS resource set have the same time interval as the time interval of scheduling the uplink grant DCI of the SRS resource. The unit of the time interval may be a slot or a symbol.

In an optional scheme, the step of enabling the SRS on each transmission granule to belong to one SRS resource specifically includes:

mapping the plurality of SRS resources to the plurality of transmission particles in sequence; for example, the SRS resource is mapped to each transmission particle in sequence from low to high according to the sequence number, wherein the sequence of the transmission particles is also from low to high; or mapping the SRS resource to each transmission particle in sequence from low to high according to the sequence number, wherein the sequence of the transmission particles is from high to low; or mapping the SRS resource to each transmission particle in sequence from high to low according to the sequence number, wherein the sequence of the transmission particles is from high to low; or mapping the SRS resource to each transmission particle in sequence from low to high according to the sequence number, wherein the sequence of the transmission particles is from high to low;

or configuring an identification index of a plurality of transmission particles.

For example: the frequency domain information of SRS resource needs to be determined by C _ SRS, B _ SRS, B _ hop. The frequency domain information may include a starting PRB number of the SRS resource and/or a number of PRBs occupied by the SRS resource. At the time of step S200 or step S300 or step S400 or step S500, we only need one set of C _ SRS, B _ SRS, B _ hop, but a predefined rule is needed how to associate each SRS resource with a unique one of the subbands, such as SRS resource mapping to each subband in order, ascending or descending order. Wherein the order of the sub-bands may be ascending or descending. Or, separately adding the configuration of sub band index under one per SRS resource config, and corresponding each SRS resource to one specific subband.

Next, how to determine the frequency domain starting position and frequency domain bandwidth of SRS transmission according to the parameters C _ SRS, B _ SRS, B _ hop is described.

The base station configures C through higher layer signaling (e.g. RRC signaling) _SRS ，B _SRS ，b _hop And n _RRC And the like. Wherein, if b _hop <B _SRS Then the PUSCH is to be frequency hopped. The UE may determine the frequency domain starting position or starting PRB sequence number for each PUSCH according to table 1.

TABLE 1

Wherein m is _SRS,0 May represent the maximum bandwidth over which the SRS can hop.

For example, when C _SRS When the configuration is 4, B is different _SRS The corresponding frequency domain start positions are shown in tables 2 and 3:

TABLE 2

TABLE 3

Wherein n is _b Can be determined based on the following formula:

further, the frequency domain position of the uplink channel in each frequency hopping in a single time slot can be obtained through auxiliary calculation based on the following formula (1):

wherein n is _SRS May be an index of the number of transmissions of the SRS; f _b (n _SRS ) An index n based on the number of transmissions of the SRS _SRS Determining a frequency domain starting position of the uplink channel; n is a radical of _b B, b' and N _b’ Is a preset coefficient; mod is a remainder function;

is a multiplicative operation.

In the method depicted in fig. 2, in yet another alternative,

the SRS on the plurality of transmission particles belong to a plurality of different SRS resources, and the SRS on each transmission particle belongs to one SRS resource. The SRS may be repeated, that is, SRS resources transmitted on each subband are the same.

Optionally, each SRS resource in the plurality of SRS resources is multiplied by a low to average power ratio (PAPR) sequence or Cyclic Shift (CS) for transmission.

Optionally, the low PAPR sequence includes, but is not limited to: ZC (Zadoff-Chu), CGS (Computer Generated Sequence), or OCC (orthogonal cover coding).

Optionally, the low PAPR sequence is obtained according to the number of the low PAPR sequence sets and the transmission particle sequence number;

or configuring the low PAPR sequence according to a high-layer signaling;

or extracting the low PAPR sequence from the low PAPR sequence set in sequence.

In the alternative scheme, after multiplying the SRS resource by the low PAPR sequence or Cyclic shift, the SRS resources of different sub-bands can be distinguished by the low PAPR sequence or Cyclic shift, so that mutual interference of the SRS resources in a repeated manner is avoided, and the PAPR can be effectively reduced.

Referring to fig. 3, fig. 3 is a method for sending an uplink probe to a UE according to an embodiment of the present invention, where the method is executed in a system shown in fig. 1, and the method is shown in fig. 3, where the method includes, but is not limited to, the following steps:

step S300, the UE transmits the SRS on a plurality of different sub-bands of the same symbol, and the SRS on the plurality of sub-bands belong to the same SRS resource;

in an alternative embodiment, the plurality of sub-bands may be 2 sub-bands, for convenience of description, the sub-bands #1 and #2 are taken as examples,

specifically, the implementation method of step S300 may specifically include:

the UE transmits SRS on the sub band #1 of the same symbol, transmits SRS on the sub band #2, and the SRS transmitted by the sub band #1 and the sub band #2 belong to the same SRS resource, wherein,

parameters of SRS resources

Can be as follows:

wherein a sub band # of 2 equals the total number of subbands.

The meaning of the parameters of the above formula can be seen in the definition of the mapping manner of the SRS by the protocol (38.211).

Step S301, the base station schedules the UE to transmit more intensive SRS above the sub-band # 1. That is, the SRS may occupy the entire bandwidth of the sub-band #1 or occupy a portion of the bandwidth of the sub-band # 1.

According to the technical scheme, the UE transmits the SRS on the different subbands of the same symbol, and then the base station schedules the UE to transmit the denser SRS on the sub band #1, so that the SRS is partially detected, and the utilization rate of network resources is improved.

Referring to fig. 4, fig. 4 is a method for transmitting an uplink probe of a UE according to an embodiment of the present invention, where the method is executed in a system shown in fig. 1, and the method is shown in fig. 4, where the method includes, but is not limited to, the following steps:

s400, UE transmits SRS on a plurality of different subbands of the same symbol, and the SRS on a plurality of subbands corresponds to a plurality of SRS resources;

in an alternative embodiment, the plurality of subbands may be 2 subbands, and for convenience of description, the subband #1 and the subband #2 are taken as examples, and the SRS resource may be 2 SRS resources, that is, an SRS resource 1 and an SRS resource 2.

Optionally, if the SRS is a periodic or semi-persistent SRS, the periods of all SRS resources within one SRS resource set are the same and the offsets are the same. Wherein, the period and the offset are configured by the base station through higher layer signaling (such as RRC).

Optionally, if the SRS is aperiodic, the time domain starting positions of all SRS resources within one SRS resource set are the same. Or, all SRS resources in one SRS resource set have the same time interval as the time interval of the uplink grant DCI scheduling the SRS resource. The unit of the time interval may be a time slot or a symbol, and the time interval may be configured by the base station through higher layer signaling (e.g., RRC). Specifically, the mapping to the plurality of subbands in order may include: the UE transmits SRS resource 1 on sub #1 and SRS resource 2 on sub #2 of the same symbol. Specifically, configuring the identifier index of the multiple transmission particles may specifically include: the UE transmits SRS resource 1 on the sub band #1 of the same symbol, and transmits SRS resource 2 on the sub band # 2; alternatively, the UE transmits SRS resource 2 on sub #1 and SRS resource 1 on sub #2 of the same symbol.

Step S401: the base station schedules the UE to transmit a denser SRS above the subband # 2.

According to the technical scheme, the UE transmits the SRS on different subbands in the same symbol, and then the base station schedules the UE to transmit the denser SRS on the subband # 2.

Referring to fig. 5, fig. 5 is a method for transmitting an uplink probe of a UE according to an embodiment of the present invention, where the method is executed in a system shown in fig. 1, and the method is shown in fig. 5, where the method includes, but is not limited to, the following steps:

step S500, the UE transmits SRS on a plurality of different subbands of the same symbol, where the SRS on the plurality of subbands corresponds to a plurality of SRS resources.

In an alternative embodiment, the multiple subbands may be 2 subbands, for convenience of description, the subband #1 and the subband #2 are taken as examples, and the SRS resource may be 2 SRS resources, that is, an SRS resource 1 and an SRS resource 2.

The SRS resources can be respectively multiplied by a low PAPR sequence or Cyclic shift and then transmitted.

The low PAPR sequence includes, but is not limited to: ZC, CGS or OCC.

Specifically, SRS resource 1 of subband #1 is SRS resource 1 × low PAPR sequence 1; SRS resource 2 × low PAPR sequence 2 of the subframe # 2; the low PAPR sequence 1 and the low PAPR sequence 2 may be extracted from a low PAPR sequence set. Wherein, the symbol transmitted on each RE of the SRS resource may be multiplied by element-wise with each element of the low PAPR sequence.

Taking Cyclic shift as an example, specifically, SRS resource 1 × Cyclic shift1 of sub-band # 1; SRS resource 2 Cyclic shift2 of subband # 2. Where, it may be that the symbol transmitted on each RE of the SRS resource is multiplied by Cyclic shift.

As an embodiment, the sequence number of the low PAPR sequence multiplied by the SRS transmitted on each subband or the Cyclic shift sequence number may depend on at least one of the following parameters: the method comprises the following steps of sub-band sequence number, SRS starting PRB sequence number, SRS starting RE sequence number, SRS frequency domain length, SRS retransmission times, the number of OFDM symbols of the SRS, the sequence number of the SRS starting OFDM, the sequence number of slot where the SRS is located and the sequence number of a wireless frame where the SRS is located.

As an embodiment, the sequence number of the low PAPR sequence multiplied by the SRS transmitted on each subband may depend on the sequence number of the subband where the SRS is located.

As an embodiment, the Cyclic shift sequence number or the value multiplied by the SRS transmitted on each subband may depend on the sequence number of the subband where the SRS is located.

As an example, CS _ index (Cyclic shift1) (a × sub _ index + b) mod (CS #), where CS # represents the total number of elements in the optional CS set. Wherein CS _ index represents the serial number of Cyclic shift; sub band _ index indicates the sequence number of the sub band; a. b is a coefficient parameter, for example, a may take a value of 1, b may take a value of 0, or a and b may take other values, which is not limited in this application.

As another example, CS _ index (for example, PRB, Cyclic shift1) — (a + SRS starting PRB index + b) mod (CS #), where CS _ index represents a Cyclic shift sequence number; CS # represents the total number of elements in the alternative CS set; the SRS starting PRB index/RE index represents the PRB sequence number or the RE sequence number of the SRS starting; a. b is a coefficient parameter, for example, a may take a value of 1, b may take a value of 0, or a and b may take other values, which is not limited in the present invention.

As yet another example, CS _ index (Cyclic shift2) (a × SRS starting RE index + b) mod (CS #), where CS _ index represents the serial number of Cyclic shift; CS # represents the total number of elements in the alternative CS set; the SRS starting PRB index/RE index represents the PRB sequence number or the RE sequence number of the SRS starting; a. b is a coefficient parameter, for example, a may take a value of 1, b may take a value of 0, or a and b may take other values, which is not limited in the present invention.

As yet another example, CS _ index (a + SRS starting PRB index + b + SRS starting RE index + c) mod (CS #), where CS _ index represents a Cyclic shift sequence number; CS # represents the total number of elements in the alternative CS set; the SRS starting PRB index/RE index represents the PRB sequence number or the RE sequence number of the SRS start; a. b and c are coefficient parameters, for example, a may take the value 1, b may take the value 1, c may take the value 0, or a, b and c may take other values, which is not limited in the present invention.

As a variation, the CS index (Cyclic shift number) used by each subband may be directly configured through higher layer signaling (e.g., RRC signaling or other control signaling). For example, CS-4 is used for the above-mentioned compound, and CS-0 is used for the compound of Subband-0. (it is assumed here that CS numbers count from 0, CS-x denotes CS numbers with x, subband numbers count from 0, and subband-y denotes subbands with y).

As a further variation, the CS sequence number used in the first subband (e.g., subband-0) or a specific subband may be directly configured through higher layer signaling (e.g., RRC signaling or other control signaling). And the CS of other sub-bands can carry out operations of +1 or-1 in sequence according to the indicated CS sequence number.

For example, CS-4 is used for sub-0, CS-5 is used for sub-1, CS-6 is used for sub-2, and so on (if all CS numbers are used up, the serial numbers are used repeatedly from 0, namely in positive order). Or, CS-4 is used for suband-0, CS-3 is used for suband-1, CS-2 is used for suband-2, and so on (if all CS numbers are used up, the sequence is repeated from the last CS number, namely the reverse order is used)

As a further variation, the mapping relationship between the subband sequence numbers and the CS sequence numbers may be predefined, and may be a CS cyclic mapping relationship. For example, subaband-0 corresponds to CS-1, subaband-2 corresponds to CS-2, subaband-3 corresponds to CS-3, subaband-4 corresponds to CS-4, subaband-5 corresponds to CS-1, and subaband-6 corresponds to CS-2. And so on, the CS is mapped on each subband in a loop.

As a further variation, the mapping relationship between the subband sequence numbers and the CS sequence numbers may be predefined, and may be a CS cyclic mapping relationship. For example, sub-8 corresponds to CS-1, sub-7 corresponds to CS-2, sub-6 corresponds to CS-3, sub-5 corresponds to CS-4, sub-4 corresponds to CS-1, and sub-3 corresponds to CS-2. And so on, the CS is mapped on each subband in a loop.

According to the technical scheme, after the SRS resource is multiplied by the low PAPR sequence or the Cyclic shift, the SRS resources can be distinguished through the low PAPR sequence or the Cyclic shift, so that mutual interference of the SRS resources in a repeated mode is avoided, and the PAPR can be effectively reduced.

Step S501: the base station schedules the UE to transmit a denser SRS on one or more subbands.

According to the technical scheme, the UE transmits the SRS on the different subbands of the same symbol, and then the base station schedules the UE to transmit the denser SRS on one or more subbands, so that the SRS is partially detected, the network resource utilization rate is improved, the SRS on each transmission particle belongs to one SRS resource, the PAPR is reduced, and the communication efficiency is improved.

As one example, the base station may instruct the UE to transmit denser SRS over one or more subbands through MAC-CE or DCI. Specifically, the indication may be performed by using a bitmap (bitmap), where each bit of the bitmap corresponds to a subband. For example, 0010 indicates that the UE transmits a denser SRS on the second subband. The method of the embodiments of the present application is set forth above in detail and the apparatus of the embodiments of the present application is provided below.

Optionally, if the SRS is a periodic or semi-persistent SRS, the period of all SRS resources within one SRS resource set is the same and the offset is the same.

Optionally, if the SRS is aperiodic, the time domain starting positions of all SRS resources within one SRS resource set are the same. Or, all SRS resources in one SRS resource set have the same time interval as the time interval of scheduling the uplink grant DCI of the SRS resource. The unit of the time interval may be a time slot or a symbol, and the time interval may be configured by the base station through higher layer signaling (e.g., RRC).

In an optional scheme, the that the SRS on each transmission granule belongs to one SRS resource specifically includes:

mapping the plurality of SRS resources to the plurality of transmission particles in sequence;

For example: the frequency domain information of SRS resource needs to look at C _ SRS, B _ SRS, B _ hop. At the time of step S200 or step S300 or step S400 or step S500, we only need one set of C _ SRS, B _ SRS, B _ hop, but a predefined rule is needed how to associate each SRS resource with a unique suband, such as SRS resource is mapped onto each suband in order, ascending or descending order. Alternatively, the configuration of sub band index under one SRS resource config is added separately.

In the user equipment depicted in fig. 6, in yet another alternative,

the SRS on the plurality of transmission particles belong to a plurality of different SRS resources, and the SRS on each transmission particle belongs to one SRS resource. The SRS may be in a repeated manner, that is, SRS resources transmitted on each transmission granule are the same.
