Example 1

In the embodiment of the present disclosure, the uplink measurement reference signal may be sent by using a time domain OCC, where the time domain OCC is less than or equal to the frequency domain repeated transmission parameter R of the uplink measurement reference signal in a slot. The frequency domain repeated transmission parameter R of the uplink measurement reference signal indicates that the frequency reference resource occupied by the measurement reference signal on the R time domain symbols is the same, wherein the frequency domain resource includes at least one of the following resources: PRB, subcarrier in PRB.

The base station informs the terminal of the time domain OCC used for measuring the reference signal. For example, a measurement reference signal includes a port, which may correspond to an OCC as shown in Table 1, and Table 1 is a schematic table 1 according to Example 1:

Table 1

测量参考信号端口Measurement reference signal port	OCCOCC
端口0Port 0	[1，1，1，1][1,1,1,1]
端口1Port 1	[1，-1，1，-1][1,-1,1,-1]
端口2Port 2	[1，1，-1，-1][1,1,-1,-1]
端口3Port 3	[1，-1，-1，1][1,-1,-1,1]

In Table 1, different OCCs correspond to different ports, as shown in FIG. 7 and FIG. 8, which are mappings of OCC to time domain symbols, and FIG. 7 is a port 0 corresponding to time domain OCC and time domain symbols according to the present disclosure. Schematic diagram of the mapping relationship, Figure 7 is the mapping of OCC to time domain symbols of port 0. 8 is a schematic diagram of a mapping relationship between port 1 corresponding to time domain OCC and time domain symbols according to the present disclosure, and FIG. 8 is a mapping of OCC to time domain symbols of port 1. At this time, the signaling reference signal port index may be signaled. For example, SRS resource 1 includes port 0, and SRS resource 2 includes port 1, although SRS resource 1 and SRS resource 2 both include one port, but one of them Corresponding to port 0, one corresponding port 1. The SRS resource 1 and the SRS resource 2 may be SRS resources allocated to different terminals. The four time domain symbols participating in the time domain OCC in FIG. 7 and FIG. 8 may be consecutive time domain symbols, or may be non-contiguous time domain symbols, may be time domain symbols in one slot, or may be in multiple slots. Time domain symbol.

In another embodiment of the present embodiment, the base station directly signals the OCC index, and one SRS resource corresponds to one OCC, and multiple ports included in one SRS resource share one OCC, as shown in Table 2, and Table 2 is based on Schematic Table 2 of Example 1.

Table 2

OCC索引OCC index	OCCOCC
索引0Index 0	[1，1，1，1][1,1,1,1]
索引1Index 1	[1，-1，1，-1][1,-1,1,-1]
索引2Index 2	[1，1，-1，-1][1,1,-1,-1]
索引3Index 3	[1，-1，-1，1][1,-1,-1,1]

For example, the SRS resource 3 and the SRS resource 4 are resources including four SRS ports, the SRS resource 3 corresponds to the OCC index 0, the SRS resource 4 corresponds to the OCC index 1, and the four SRS ports in the SRS resource 3 share the time domain OCC. [1, 1, 1, 1]. In another implementation manner of this embodiment, all SRS ports included in all SRS resources in one SRS resource set share one time domain OCC index. Of course, this embodiment does not exclude that different SRS ports in one SRS resource use different time domain OCCs.

In the above manner of the embodiment, the base station notifies the time domain OCC index used by the terminal SRS by using the signaling information, such as the port index used for notifying the SRS in the signaling, or notifying the time domain OCC index used by the SRS. The base station may further notify the length information of the time domain OCC by signaling.

In another implementation manner of this embodiment, the base station may also agree with the terminal to enable the terminal to obtain the foregoing information by using a predetermined rule. For example, the terminal may obtain the OCC index (or port index) used by the SRS resource ID. The time domain OCC code index OCC _index = (SRSID) modT, where SRSID is the identification (ID) of the SRS resource, T is the total number of available OCCs, or the length of the time domain OCC. Similarly, the time domain OCC index can be obtained by using an ID of an SRS resource group (SRS resource group or SRS resource set) in which the SRS resource is located, or an identifier of the terminal, such as by using a C-RNTI.

In the present application, the uplink measurement reference signal may also be referred to as an uplink sounding reference signal.

Example 2

In this example, the time domain OCC of the SRS is associated with the SRS sequence.

In an embodiment, the length of the time domain OCC of the SRS is related to whether the SRS sequence is associated with a time domain symbol change, or whether the time domain OCC of the SRS is enabled and whether the SRS sequence is associated with a time domain symbol change. Or the length of the time domain OCC of the SRS is related to whether the SRS sequence parameter is any time domain symbol change, wherein the SRS sequence parameter may be one or more of the following parameters: a sequence group number, a sequence number.

In an embodiment, the length of the time domain OCC of the SRS is 1, and the time domain OCC, which may also be referred to as SRS, is not enabled. The length of the time domain OCC of the SRS is greater than 1, and may also be referred to as the time domain OCC enable of the SRS.

In the case where the length of the time domain OCC of the SRS is greater than 1, the sequence of the SRS is constant in the time domain symbol in which the time domain OCC is located. In the case where the length of the time domain OCC of the SRS is equal to 1, the sequence of the SRS is variable in the time domain symbol in which the time domain OCC is located. and / or

In the case where the length of the time domain OCC of the SRS is greater than 1, the sequence group number of the SRS is constant in the time domain symbol in which the time domain OCC is located. In the case where the length of the time domain OCC of the SRS is equal to 1, the sequence group number of the SRS is variable in the time domain symbol in which the time domain OCC is located. and / or

In the case where the length of the time domain OCC of the SRS is greater than 1, the sequence number of the SRS is constant in the time domain symbol in which the time domain OCC is located. In the case where the length of the time domain OCC of the SRS is equal to 1, the sequence number of the SRS is variable in the time domain symbol in which the time domain OCC is located.

In an embodiment, the sequence of SRS in NR

Obtained by the following formula:

When the time domain OCC is adopted, the reference signal transmitted on the SRS is obtained by the following formula:

among them,

Is the sequence length of the SRS, m is the number of PRBs occupied by the SRS, δ is the total number of combs in the Interleaved Frequency Division Multiple Access (IFDMA) mode, and α is a cyclic shift parameter.

It belongs to {0, 1} or is fixed to 0. w(l) is the element of the time domain OCC on the time domain symbol 1, or the phase scrambling factor of the time domain OCC on the time domain symbol 1.

In an embodiment, when

When fixed to 0, the above formula (1-0) is equivalent to:

In the present application, the sequence corresponding to the SRS is a symbol set communication to be sent by the SRS before multiplying the time domain OCC, for example, a plurality of resource elements (Resource Element, RE) occupied by the SRS on a time domain symbol are to be sent by the SRS. A plurality of symbols constitute the one sequence, that is, in the formula (1-1)

A sequence corresponding to the SRS is constructed.

When the sequence length of SRS

more than the

(

Is the number of subcarriers included in a PRB, such as in LTE and NR,

When it is 12)

v is the serial number, belonging to {0, 1}, 0 ≤ α ≤ 2π,

Is less than or equal to

The largest prime number. In an embodiment, when the number of PRBs occupied by the SRS is less than 6, v is 0, otherwise v may be 0 or 1

When the sequence length of SRS

Less than or equal to

When said

among them,

According to the sequence group number u, a predetermined table is obtained.

Where u is the sequence group number, u is obtained by the following formula:

u=(f _gh (n _s )+f _ss )mod30 (1)

Where c(z) is the zth value in the pseudo-random (Pseudo-random) sequence, and given an initialization value c _init , a random sequence can be generated. Where the initial value in the sequence generation is

among them,

It is a parameter of the high-level configuration or a physical cell identification number.

Among them, a 31-length pseudo-random (Pseudo-random) sequence is generated as follows.

c(n)=(x ₁ (n+N _C )+x ₂ (n+N _C ))mod2

x ₁ (n+31)=(x ₁ (n+3)+x ₁ (n)) mod2

x ₂ (n+31)=(x ₂ (n+3)+x ₂ (n+2)+x ₂ (n+1)+x ₂ (n)) mod2

n=0,1,...,M _PN -1,N _C =1600, x ₁ (0)=1, x ₁ (n)=0, n=1,2,...,30,

In equation (2) h() is a function of the time parameter, whereby the sequence group number corresponding to a measurement reference signal port or a measurement reference signal resource changes with the time domain symbol.

However, when the SRS adopts time domain OCC orthogonality, so that two SRS resources 1 and SRS resources 2 with overlapping frequency domains are orthogonal to each other, FIG. 9 is that two SRS resources partially overlapped in the frequency domain according to the present disclosure. Schematic diagram of time domain OCC orthogonalization, as shown in FIG. 9, in order to make the port in SRS resource 1 and the port in SRS resource 2 orthogonal, time domain OCC can be adopted, because SRS resource 1 and SRS resource 2 overlap. The corresponding sequence is different. In this case, for orthogonality, the SRS resource 1 uses the same sequence on the two time domain symbols in which the time domain OCC is located, and the SRS resource 2 uses the same on the two time domain symbols in which the time domain OCC is located. the sequence of. Therefore, the sequence group number u does not change in the time domain symbol in which the time domain OCC is located.

That is, the time domain symbol index is not included in the h() function, or the time values of the time domain symbols in the h() function for the time domain OCC are the same.

Therefore, when the base station can agree with the terminal that the length of the current domain OCC is greater than 1, the time domain symbol index is not included in the acquisition parameter of h(). When the length of the domain OCC is 1, the time domain symbol index is included in the acquisition parameter of h(). Or when the base station and the terminal agree that the length of the time domain OCC is greater than 1, the sequence group number u is not enabled with time hopping. When the length of the domain OCC is 1, the sequence group number u is enabled with time hopping. Or when the base station can agree with the terminal that the length of the current domain OCC is greater than 1, the value of h() is the same in multiple time domain symbols in which the time domain OCC is located. When the length of the domain OCC is equal to 1, the time domain OCC is located. On multiple time domain symbols, the value of h() can be different.

Similarly, for example, the serial number v is obtained by the following formula:

When the sequence number hopping is enabled, v=c(z ₁ ), the base station can agree with the terminal that the length of the current domain OCC is greater than 1, the time domain symbol index is not included in the acquisition parameter of z ₁ , and the length of the domain OCC is equal to 1 when the length of the field OCC is equal to 1 The acquisition parameter of z ₁ includes the time domain symbol index. When the length of the time domain OCC is greater than 1 by the base station and the terminal, the jump of the sequence number v with time is not enabled. When the length of the domain OCC is 1, the serial number v hopping over time is enabled. Or the base station can agree with the terminal that the length of the current domain OCC is greater than 1, and the value of z _{1 is} the same in multiple time domain symbols in which the time domain OCC is located. When the length of the domain OCC is equal to 1, the time domain OCC is located. On multiple time domain symbols, the value of z ₁ can be different.

In the above embodiment, the length of the time domain OCC is related to the sequence, and may also be related to the code set and sequence of the time domain OCC. For example, the terminal and the base station agree that the time domain OCC belongs to the set 1={(1,1,1,1)}. When the acquisition parameter of h() includes the time domain symbol index, or the sequence group number u is enabled over time, or h() may have different values on the four time domain symbols in which the time domain OCC is located; The time domain OCC belongs to the set 2={(1,-1,1,-1), (1,1,-1,-1), (1,-1,-1,1)}, h() The time domain symbol index is not included in the acquisition parameter, or the sequence group number u is not enabled over time, or h() has the same value on the four time domain symbols in which the time domain OCC is located.

Similarly, the code set of the time domain OCC may be related to the sequence number v. For example, when the terminal and the base station agree that the time domain OCC belongs to the set 1={( ₁ , ₁ , ₁ , ₁ )}, the acquisition parameters of z ₁ are included. The time domain symbol index, or the sequence number v is enabled over time, or z ₁ may be different in the four time domain symbols in which the time domain OCC is located, and the time domain OCC belongs to the set 2={(1,- 1,1,-1), (1,1,-1,-1), (1,-1,-1,1)}, the time domain symbol index, or serial number is not included in the acquisition parameter of z ₁ v The transition over time is not enabled, or z ₁ has the same value on the four time domain symbols in which the time domain OCC is located.

The above division of the code set 1 of the time domain OCC and the code set 2 of the time domain OCC are merely examples, and other division manners are not excluded. In short, there is an association between the time domain code set and the generation mode of the sequence. Or there is an association between the time domain code set and the parameters of the sequence.

Example 3

As shown in FIG. 10, one measurement reference signal port occupies 4 symbols in one slot, and the frequency occupied by the first 2 time domain symbols. The domain resources are the same. The frequency domain positions in the last two time domain symbols are the same. The first two time domain symbols and the last two time domain symbols occupy different frequency domains. For example, the occupied PRB is different, but the occupied IFDMA is in the middle. The comb comb can be the same. In FIG. 10, the frequency domain repeated transmission parameter R represents a frequency domain resource occupied by the measurement reference signal on R time domain symbols in one time unit (frequency domain resources include frequency domain physical resource blocks PRB, and frequency domain subcarriers). Invariant, it is also possible to indicate that the measurement reference signal performs a frequency domain hopping after every R time domain symbols (ie, the measurement reference signal is transmitted on R time domain symbols), the R The time domain symbols can be in different slots or in the same time unit. The frequency domain resource includes at least one of the following: a physical resource block (PRB), a subcarrier in the PRB, and a subcarrier.

The R1 time domain symbols occupied in the same correspond to the same sequence group number (the sequence group number is the u described in the example 1); when the length of the domain OCC is greater than 1, the R1 of one SRS port occupies in one time unit The time domain symbol corresponds to the same serial number (the serial number is the v described in the example 1); when the sequence corresponding to the R1 time domain symbols occupied by one SRS port in one time unit is different, the measurement reference signal port The length of the corresponding time domain OCC is 1; when the sequence group number corresponding to the R1 time domain symbols occupied by one SRS port is different, the length of the time domain OCC corresponding to the measurement reference signal port is 1; When the sequence number corresponding to the R1 time domain symbols occupied by the SRS port is different, the length of the time domain OCC corresponding to the measurement reference signal port is 1;

In the foregoing embodiment, the R1 time domain symbols are in a time unit, such as in a slot. Of course, the embodiment does not exclude that the R1 time domain symbols may include time domain symbols in multiple time units. For example, the R1 time domain symbols include time domain symbols in more than one slot.

The corresponding transmission sequence on the domain symbol set is the same, and the sequence used by the SRS is also the same in the transmission sequence corresponding to the time domain symbol set corresponding to the time domain OCC.
