The embodiment of the invention provides a method, equipment and a system for sending a reference signal, which can receive an enabling signaling of a reference signal resource and send the reference signal on an enabling sub-resource indicated according to the enabling signaling. With this scheme, since the UE can transmit the reference signal only on the enabled sub-resource indicated by the enabled signaling, the number of sub-resources transmitting the reference signal can be reduced, and since the total energy of the UE transmitting the reference signal is constant, when the number of sub-resources transmitting the reference signal is reduced, the energy of the reference signal transmitted on each sub-resource can be increased, so that the quality of the reference signal transmitted by the UE can be improved.
The reference signal sending method provided by the embodiment of the invention can be applied to a communication system. The communication system may be a wireless communication system, which may include a network device and a UE. Fig. 1 is a schematic diagram of a wireless communication system according to an embodiment of the present invention. In fig. 1, a wireless communication system may include a network device 01 and a UE 02. Wherein a connection may be established between the network device 01 and the UE 02. It is understood that the network device 01 and the UE 02 may be a wireless connection.
Alternatively, in an embodiment of the present invention, the UE is a device that provides voice and/or data connectivity to the user, a handheld device with wired/wireless connection capabilities, or other processing device connected to a wireless modem. The UE may communicate with one or more core network devices via a radio access network (radio access network, RAN). The UE may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device that exchanges voice and/or data with the RAN, e.g., a personal communication service (personal communication service, PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital assistant (personal digital assistant, PDA) or the like. The UE may also be referred to as a user agent (UE), a UE, or the like.
In the embodiment of the invention, the network equipment is equipment which is deployed in the RAN and used for providing wireless communication functions for the UE. In the embodiment of the invention, the network equipment can be a base station, and the base station can comprise macro base stations, micro base stations, relay stations, access points and the like in various forms. In systems employing different radio access technologies, the names of base station capable devices may vary. For example, in a 5G system, it may be referred to as a 5G base station (gNB); in a fourth Generation wireless communication (4-Generation, 4G) system, such as a long term evolution (long term evolution, LTE) system, it may be referred to as an evolved Node B (eNB); in a third generation mobile communication (3G) system, it may be called a base station (Node B) or the like. As communication technology evolves, the name "base station" may change.
In the embodiment of the invention, after the network equipment configures the resource of the reference signal (for example, the reference signal resource in the embodiment of the invention) for the UE to send the reference signal to the UE, the network equipment can instruct the UE to send the reference signal on the sub-resource with better signal quality in the resource according to the signal characteristic, so that the energy of the reference signal sent by the UE on each sub-resource can be increased, the quality of the reference signal sent by the UE can be improved, and the accuracy of channel estimation can be improved.
The reference signal transmission method provided by the embodiment of the invention is exemplarily described below with reference to various drawings.
As shown in fig. 2, an embodiment of the present invention provides a reference signal transmission method, which includes the following steps S201 to S203.
S201, the network device sends an enabling signaling of the reference signal resource to the UE.
S202, the UE receives the enabling signaling of the reference signal resource.
S203, the UE transmits a reference signal on an enabled sub-resource indicated by the enabled signaling.
In the embodiment of the invention, the network equipment can send the enabling signaling of the reference signal resource to the UE according to the channel characteristic, so that after the UE receives the enabling signaling, the UE can send the reference signal on the enabling sub-resource indicated by the enabling signaling according to the enabling signaling, so that the UE can send the reference signal only on the enabling sub-resource indicated by the enabling signaling, namely, the number of the sub-resources for sending the reference signal can be reduced, and the energy of the UE for sending the reference signal on each enabling sub-resource can be increased, thereby improving the quality of the reference signal sent by the UE.
It is to be appreciated that the above-described enabling sub-resources can be resources in the reference signal resources.
In addition, the UE may not transmit the reference signal on the non-enabled sub-resources (resources of the reference signal resources) indicated by the above-described enabled signaling.
Optionally, in an embodiment of the present invention, the reference signal may be SRS.
In the embodiment of the present invention, the reference signal resource may be a resource configured by the network device to send a reference signal to the UE configured by the UE, that is, a resource that the UE originally sends the reference signal.
Optionally, in the embodiment of the present invention, the network device may send configuration signaling to the UE and configure reference signal resources to the UE.
For example, in the case where the reference signal is SRS, the configuration signaling may be SRS configuration signaling.
Alternatively, in the embodiment of the present invention, the reference signal may be a periodic reference signal or a semi-persistent reference signal.
It should be noted that, in order to clearly describe the reference signal transmission method provided in the embodiment of the present invention, examples in the following embodiments are all exemplified by taking a reference signal as an SRS and configuration signaling as an SRS configuration signaling, which is not limited in any way to this application. In practical implementation, the reference signal may be any other possible signal, and the configuration signaling may be any other possible configuration signaling, which may be specifically determined according to practical use requirements, and embodiments of the present invention are not limited.
Alternatively, in the embodiment of the present invention, the UE may send the reference signal on the enable sub-resource in a different order.
A first possible implementation: and the UE transmits the reference signals on the enabling sub-resources according to the time domain sequence. That is, the enabling order may be a time domain order.
A second possible implementation: the UE transmits reference signals on the enabled sub-resources in order from low frequency to high frequency. That is, the order of enabling may be in a frequency domain order from small to large.
A third possible implementation: the UE transmits reference signals on the enabled sub-resources in order from high frequency to low frequency. That is, the order of enabling may be in frequency domain order from large to small.
In the embodiment of the invention, the UE can send the reference signals on the enabling sub-resources according to different sequences, so that the sequence of sending the reference signals by the UE is flexible.
Alternatively, in the embodiment of the present invention, the enabling signaling may include two possible forms, namely, form one and form two. These two forms (form one and form two) are each exemplified below.
Form one: the enabling signaling may be a bitmap (i.e., bitmap).
Alternatively, in the embodiment of the present invention, 1 bit in the bitmap may correspond to 1 sub-resource, and the sub-resource may be an enabled sub-resource or a non-enabled sub-resource.
Optionally, in the embodiment of the present invention, when the value of 1 bit in the bitmap is "1", the UE may be indicated to enable on the sub-resource corresponding to the bit (i.e., the UE may send the reference signal on the sub-resource), where the sub-resource may be an enabled sub-resource; when the value of 1 bit in the bitmap is "0", it may indicate that the UE is not enabled on the sub-resource corresponding to the bit (i.e., the UE may not send the reference signal on the sub-resource), where the sub-resource may be a non-enabled sub-resource. Or when the value of 1 bit in the bitmap is "0", the UE may be indicated to enable on the sub-resource corresponding to the bit, that is, the sub-resource may be an enabled sub-resource; when the value of 1 bit in the bitmap is "1", it may indicate that the UE is not enabled on the sub-resource corresponding to the bit, that is, the sub-resource may be a non-enabled sub-resource. The method can be specifically determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in the embodiment of the present invention, the bandwidth of the sub-resource (i.e. the bandwidth of the sub-resource) may be related to at least one of the following: the subband bandwidth (b_subband) and the spreading factor (beta, which may also be referred to as subband spreading factor) of the above reference signal.
Optionally, in the embodiment of the present invention, when the reference signal is sent in a frequency hopping manner (hereinafter referred to as frequency hopping of the reference signal), the subband bandwidth of the reference signal may be a single frequency hopping bandwidth (b_single); in the case where the reference signal is transmitted in a non-frequency hopping manner (hereinafter, simply referred to as reference signal does not hop), the subband bandwidth of the reference signal may be the minimum bandwidth of the reference signal.
Wherein, the single-hop bandwidth can be obtained through the configuration signaling of the reference signal.
Optionally, in the embodiment of the present invention, in the case of frequency hopping of the reference signal, the subband bandwidth of the reference signal may also be the minimum bandwidth of the reference signal. The method can be specifically determined according to actual use requirements, and the embodiment of the invention is not limited.
Alternatively, in the embodiment of the present invention, the minimum bandwidth of the reference signal may be 4 Resource Blocks (RBs).
Of course, in actual implementation, the minimum bandwidth of the reference signal may be any other possible value, which may be specifically determined according to the actual use requirement, and the embodiment of the present invention is not limited.
Optionally, in an embodiment of the present invention, the single hop bandwidth may be obtained through configuration signaling of a reference signal.
Alternatively, in the embodiment of the present invention, the expansion coefficient may be an integer greater than or equal to 1. Wherein the expansion coefficient can be obtained through the configuration signaling of the reference signal.
Optionally, in the embodiment of the present invention, the subband bandwidth of the reference signal may be a value reported by a terminal or a protocol assignment or a network device configuration. The method can be specifically determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in an embodiment of the present invention, the number of bits of the bitmap (i.e. the length of the bitmap) may be related to at least one of the following: the sounding bandwidth (b_full) of the reference signal, the subband bandwidth of the reference signal, the total frequency hopping number of the reference signal, and the expansion coefficient.
It should be noted that, the probing bandwidth of the reference signal may be a complete probing bandwidth configured by the network device to the UE. The detection bandwidth of the reference signal can be obtained through configuration signaling of the reference signal.
Optionally, in the embodiment of the present invention, in a case where the reference signal does not hop, the bit number (length of bitmap) of the bitmap may be determined by at least one of the following: the sounding bandwidth of the reference signal (i.e., b_full), the subband bandwidth of the reference signal (b_subband), and the expansion coefficient (beta).

In the embodiment of the present invention, the total frequency hopping frequency of the reference signal may be frequency hopping performed by taking a single frequency hopping bandwidth as a unit, so as to obtain the frequency hopping frequency (i.e., the total frequency hopping frequency may be b_full/B-single) required by a complete detection bandwidth (i.e., the detection bandwidth of the reference signal). Wherein, the total frequency hopping number can be obtained through the configuration signaling of the reference signal.
Alternatively, in the embodiment of the present invention, when the types of the reference signal resources are different, the total frequency hopping times may be different.
Taking the reference signal resource as the SRS resource as an example, if the SRS resource is non-periodicThe periodic resources, then the total frequency hopping number can be the ratio of the number of symbols occupied by SRS resources (Ns) to the number of repetitions (R) (i.e
Figure BDA0002378472610000062
). If the SRS resource is a periodic resource or a semi-persistent resource, the total frequency hopping number can be obtained from a parameter indicated by the SRS's configuration signaling (also referred to as a UE-derived parameter), e.g., configuration parameter B SRS Configuration parameter C SRS Configuration parameters b hop SRS Bandwidth configuration Table (SRS bandwidth configuration table) and frequency hopping formula->

Table 1 SRS bandwidth configuration table
In the embodiment of the present invention, taking the reference signal as an example of SRS, whether the SRS hops or not may be determined according to whether the SRS resource is configured to hop. Specifically, the condition of whether the SRS resource is configured to hop may be b hop <B SRS In this condition, whether or not the aperiodic SRS resource is configured to hop may be determined according to the number of symbols (Ns) and the number of repetitions (R) occupied by the SRS resource in the configuration instruction of the SRS. Wherein Ns can be configured as: ns= {1,2,4}, the set that R can configure is r= {1,2,4}, and R is less than or equal to Ns.
In the embodiment of the present invention, according to the above configuration manner, the configuration conditions of the SRS resource may include three possible conditions, which may be respectively: the SRS resource is not configured with hopping (hereinafter referred to as case one), the SRS resource is configured with hopping but is not configured with repetition (hereinafter referred to as case two), and the SRS resource is configured with hopping and is configured with repetition (hereinafter referred to as case three).
In the embodiment of the present invention, in the above case one (the SRS resource is not configured for frequency hopping), in each slot (slot), all ports of the SRS resource may be mapped to Ns configured symbols, and the same set of physical resource blocks (physical resource block, PRBs) of each port on the Ns configured symbols occupy the same set of subcarriers (i.e. the same frequency domain resource).
That is, when r=ns, the SRS resource is not configured for frequency hopping because there is no frequency hopping packet.
In the embodiment of the present invention, in the case two (where frequency hopping is configured in the SRS resource but repetition is not configured), each port of the SRS resource may be mapped to a different subcarrier set on each OFDM symbol, that is, the frequency domain resource on each OFDM symbol is different, in each slot and between slots.
In the case where frequency hopping is configured within SRS resources but repetition is not configured, r=1. Wherein the number of hopping groups may be equal to Ns/R and the number of orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols within the hopping groups may be equal to 1.SRS resources may be based on configuration parameter B SRS Configuration parameter C SRS Configuration parameters b hop Or frequency hopping formula frequency hopping. The comb values (comb values) of the different subcarrier sets are the same.
In the case where frequency hopping is configured in SRS resources but repetition is not configured, for ns=1, there are 1 OFDM symbol in each slot for SRS transmission, and frequency hopping (i.e., frequency domain resources are different) is required between slots (i.e., between OFDM symbols). That is, when ns=1, inter-slot hopping (inter-slot hopping) may be performed.
In the case where frequency hopping is configured in SRS resources but repetition is not configured, for ns=2 (or ns=4), there are 1 (or 2) OFDM symbols in each slot for SRS transmission, frequency hopping is required in a slot, and one frequency hopping group contains 1 OFDM symbol, where frequency hopping is also required between slots, that is, each OFDM symbol is frequency hopped. That is, when ns=2 (or ns=4), intra-slot frequency hopping (i.e., intra-slot frequency hopping) may be performed.
In the embodiment of the present invention, in the case three (where the SRS resource is configured with frequency hopping and configured to be repeated), in the case where ns=4 and r=2, each port of the SRS resource is mapped to the same subcarrier set in each frequency hopping group, and the subcarrier sets are different between the frequency hopping groups.
Specifically, the number of frequency hopping groups is equal to Ns/R, the number of OFDM symbols in the frequency hopping groups is equal to R, and the number of frequency hopping groups represents the frequency hopping times in slots. Wherein, no frequency hopping is performed in the groups (i.e. different OFDM symbols in the frequency hopping groups occupy the same frequency domain resource), and frequency hopping is performed between groups (i.e. different frequency domain resources are occupied between frequency hopping groups).
In the embodiment of the present invention, when the SRS resource is configured with frequency hopping, if the SRS resource is aperiodic (only intra-slot frequency hopping is supported in a bandwidth part (BWP)), then:
when ns=1, r=1, no frequency hopping occurs. Because one aperiodic SRS resource occupies only one OFDM symbol, and one OFDM symbol cannot realize frequency hopping. Reference may be made to the description of the above embodiment regarding case one.
When ns=2 and r=1, the SRS resource may be an aperiodic SRS resource including 2 adjacent OFDM symbols, supporting intra-slot frequency hopping. Within one BWP, the sounding bandwidth of the SRS may be divided into 2 subbands of equal bandwidth, and the full frequency hopping bandwidth may be sounding over 2 OFDM symbols. For others reference may be made to the description of case two in the above embodiments.
When ns=4 and r=1, the SRS resource may be an aperiodic SRS resource including 4 adjacent OFDM symbols, supporting intra-slot frequency hopping. Within one BWP, the sounding bandwidth of the SRS is divided into 4 subbands of equal bandwidth, and the complete hopping bandwidth is sounding over 4 OFDM symbols. For others reference may be made to the description of case two in the above embodiments.
When ns=2, r=2, the SRS resource may be an aperiodic SRS resource including 2 adjacent OFDM symbols, without frequency hopping, because the same frequency domain resource is occupied. Reference may be made to the description of the above embodiment regarding case one.
When ns=4 and r=2, the SRS resource may be an aperiodic SRS resource including 4 adjacent OFDM symbols, supporting intra-slot frequency hopping. Within one BWP, the sounding bandwidth of the SRS is divided into 2 subbands of equal bandwidth, and the full hopping bandwidth is sounding over 2 hopping groups. Reference is made to the description of case three in the above embodiments for others.
When ns=4, r=4, the SRS resource may be an aperiodic SRS resource including 4 adjacent OFDM symbols, without frequency hopping, because the same frequency domain resource is occupied. Reference may be made to the description of the above embodiment regarding case one.
In the embodiment of the present invention, when the SRS resource is configured with frequency hopping, if the SRS resource is a periodic resource/semi-persistent resource (in one BWP, intra-slot frequency hopping and inter-slot frequency hopping are supported), then:
when ns=1 and r=1, inter-slot hopping is supported, and other reference is made to the description of the second case in the above embodiment.
When ns=2 and r=1, the SRS resource may be an SRS resource including 2 adjacent symbol OFDM numbers, and support intra-slot frequency hopping and inter-slot frequency hopping. The SRS resource may be frequency hopped in units of 1 OFDM symbol. For others reference may be made to the description of case two in the above embodiments.
When ns=4 and r=1, the SRS resource may be an SRS resource including 4 adjacent OFDM symbols, supporting intra-slot frequency hopping and inter-slot frequency hopping. The SRS resource may be frequency hopped in units of 1 OFDM symbol. For others reference may be made to the description of case two in the above embodiments.
When ns=2 and r=2, SRS resources of 2 adjacent OFDM symbols support inter-slot frequency hopping. In R adjacent OFDM symbols of SRS resources for each slot, each antenna port of the SRS resources is mapped to the same set of subcarriers, i.e. the SRS resources occupy the same frequency domain resources on different OFDM symbols within each slot.
When ns=4 and r=2, the SRS resource may be an SRS resource including 4 adjacent OFDM symbols, supporting intra-slot frequency hopping and inter-slot frequency hopping. Between two pairs of adjacent OFDM symbols (i.e., between hopping groups) of SRS resources in each slot, each antenna port of the SRS resources is mapped to a different set of subcarriers. In each pair of adjacent OFDM symbols (i.e., within a hop-group) of SRS resources in each slot, each antenna port of the SRS resources is mapped to the same set of subcarriers. Reference is made to the description of case three in the above embodiments for others.
When ns=4 and r=4, the SRS resource may be an SRS resource including 4 adjacent OFDM symbols, and support inter-slot frequency hopping. In R adjacent OFDM symbols of SRS resources for each slot, each antenna port of the SRS resources is mapped to the same set of subcarriers, i.e. the SRS resources occupy the same frequency domain resources on different OFDM symbols within each slot. Wherein, the SRS resources of the N OFDM symbols occupy the same symbol position (RS) in each slot.
Optionally, in the embodiment of the present invention, under the condition that the reference signal does not hop frequency, one sub-resource includes Ns OFDM symbols; in the case of reference signal hopping, one sub-resource contains N OFDM symbols, where N represents the number of symbols within the hopping group.
The above-described form one (the enabling signaling is a bitmap) will be exemplarily described below with reference to the SRS as an example.
Example 1: as shown in fig. 3, the SRS resource is assumed to be a periodic resource (i.e., periodic SRS resource), the period is 2, and the slot offset is 0 (i.e., slot offset=0); and ns=1, r=1, including 1 hopping group, and the hopping group includes 1 OFDM symbol; and one full sounding bandwidth b_full=48 RB (i.e., sounding bandwidth of srs=48 RB), total frequency hopping number=4, single frequency hopping bandwidth=12 RB, subband spreading factor=1, one subband bandwidth=12 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 4, and bitmap=1111, and the order of enabling is from small to large in frequency domain order.
Note that, the rectangle of the single frequency hopping bandwidth in fig. 3 corresponds to one slot, and only one OFDM symbol is used for transmitting SRS in one slot, and symbol positions for transmitting SRS among multiple slots are the same (i.e. symbol positions for transmitting SRS in different slots are the same).
In addition, when the period is 2, one SRS may be transmitted on every two slots. When slot offset=0, SRS may be transmitted from the first position (e.g., the first slot), that is, slots where SRS is transmitted may be slot0, slot2, slot4, slot6, slot8, slot10, slot12, and so on.
Example 2: as shown in fig. 4, the SRS resource is assumed to be a periodic resource (i.e., periodic SRS resource), the period is 2, slot offset=1; and ns=1, r=1, including 1 hopping group, and the hopping group includes 1 OFDM symbol; and one full probe bandwidth b_full=48 RB, total frequency hopping number=4, single frequency hopping bandwidth=12 RB, subband expansion coefficient=1, one subband bandwidth=12 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 4, bitmap=1001, and the enabling order is from small to large in frequency domain order.
Note that, the rectangle of the single frequency hopping bandwidth in fig. 4 corresponds to one slot, only one OFDM symbol is used for transmitting SRS in one slot, and symbol positions for transmitting SRS among multiple slots are the same.
In addition, when the period is 2, one SRS may be transmitted on every two slots. When slot offset=1, SRS may be transmitted from a second position (e.g., a second slot), that is, slots where SRS is transmitted may be slot1, slot3, slot5, slot7, slot9, slot11, and so on.
In addition, the boxes in the drawing of the example in the embodiment of the present invention may each represent an SRS that needs to be originally transmitted (i.e., the SRS is originally configured by the network to be transmitted on the resource corresponding to the dashed box), but after the network device transmits the enabling signaling, the UE does not transmit the SRS on the resource corresponding to the dashed box any more.
Example 3: assuming that the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 2, slot offset=0; and ns=1, r=1, including 1 hopping group, and the hopping group includes 1 OFDM symbol; and one full probe bandwidth b_full=48 RB, total frequency hopping number=4, single frequency hopping bandwidth=12 RB, subband expansion coefficient=2, one subband bandwidth=24 RB. At this time, as shown in fig. 5, the bit number of the bitmap (i.e., the length of bitmap) is equal to 2, and bitmap=10 and the enabling order is the time domain order. Alternatively, as shown in fig. 6, the bit number of the bitmap (i.e., the length of bitmap) is equal to 2, and bitmap=10, and the order of enabling is from small to large in frequency domain order.
Note that, the rectangles of the single frequency hopping bandwidths in fig. 5 and 6 correspond to one slot, and only one OFDM symbol is used in one slot to transmit the SRS, and symbol positions of transmitting the SRS between the slots are the same.
In addition, for the description about the period and the slot offset, reference may be specifically made to the explanation about the period and the slot offset in the above embodiment, and for avoiding repetition, the description is omitted here.
Example 4: as shown in fig. 7, the SRS resource is assumed to be a periodic resource (i.e., periodic SRS resource), the period is 2, and slot offset=0; and ns=2, r=2, including 1 hopping group, and the hopping group includes 2 OFDM symbols; and one full probe bandwidth b_full=48 RB, total frequency hopping number=4, single frequency hopping bandwidth=12 RB, subband expansion coefficient=1, one subband bandwidth=12 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 4, and bitmap=1001, and the enabling order is from small to large in frequency domain order.
Note that, the rectangle of the single frequency hopping bandwidth in fig. 7 corresponds to one slot, and only 2 OFDM symbols in one slot are used for transmitting SRS, and symbol positions for transmitting SRS between the slots are the same.
Example 5: as shown in fig. 8, the SRS resource is assumed to be a periodic resource (i.e., periodic SRS resource), and the period is 1; and ns=2, r=1, including 1 hopping group, and the hopping group includes 1 OFDM symbol; and one full probe bandwidth b_full=48 RB, total frequency hopping number=4, single frequency hopping bandwidth=12 RB, subband expansion coefficient=1, one subband bandwidth=12 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 4, and bitmap=1101, and the enabling order is the time domain order.
Example 6: as shown in fig. 9, the SRS resource is assumed to be a periodic resource (i.e., periodic SRS resource), and the period is 1; and ns=4, r=2, including 2 hopping groups, where the hopping groups include 2 OFDM symbols; and one full probe bandwidth b_full=48 RB, total frequency hopping number=4, single frequency hopping bandwidth=12 RB, subband expansion coefficient=1, one subband bandwidth=12 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 4, and bitmap=1101, and the enabling order is the time domain order.
Example 7: as shown in fig. 10, it is assumed that the SRS resource is an aperiodic resource (i.e., an aperiodic SRS resource), and ns=4, r=2, including 2 hopping groups, and the hopping groups include 2 OFDM symbols; and one full probe bandwidth b_full=48 RB, total frequency hopping number=2, single frequency hopping bandwidth=24 RB, subband expansion coefficient=1, one subband bandwidth=24 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 2, and bitmap=10, and the enabling order is the time domain order.
Example 8: as shown in fig. 11, the SRS resource is assumed to be a periodic resource (i.e., periodic SRS resource), the period is 2, and slot offset=0; and ns=2, r=2, no frequency hopping; and one full probe bandwidth b_full=48 RB, subband bandwidth=24 RB, subband expansion coefficient=1, one subband bandwidth=24 RB. At this time, the bit number of the bitmap (i.e., the length of bitmap) is equal to 4, and bitmap=1100, and the enabling order is from small to large in frequency domain order.
The second mode of the enabling signaling is described as an example below.
Form two: the enabling signaling is used to indicate at least one of: a bandwidth of the partial probe bandwidth; detecting the bandwidth of the window; detecting the initial position of the bandwidth partially; detecting the end position of the bandwidth partially; detecting comb values of comb resources in the bandwidth partially; and, an offset value (which may also be referred to as a comb offset value) of the comb resources within the partial probe bandwidth.
Wherein the partial detection bandwidth is a part or all of the detection bandwidth of the reference signal.
Alternatively, in the embodiment of the present invention, in the second form, the enabling signaling may be referred to as comb indication signaling.
It will be appreciated that the second form may be a comb indication.
Alternatively, for the second form, the enabling signaling may include first indication information and second indication information. The first indication information may be used to indicate any one of the following: the bandwidth of the partial detection bandwidth and the start position of the partial detection bandwidth, the bandwidth of the detection window and the start position of the partial detection bandwidth, the start position of the partial detection bandwidth and the end position of the partial detection bandwidth. The second indication information may be used to indicate a comb value of the comb resources within the partial detection bandwidth and an offset value of the comb resources within the partial detection bandwidth.
Alternatively, the first indication information may be a signaling, for example, a reference signal portion probe bandwidth signaling; the second indication information may also be a signaling, such as comb position signaling.
Of course, in actual implementation, the first indication information and the second indication information may also be in any other possible forms. The method can be specifically determined according to actual use requirements, and the embodiment of the invention is not limited.
Alternatively, in the embodiment of the present invention, the start position of the partial probing bandwidth, the end position of the partial probing bandwidth, or the probing window may be the start position of the configuration bandwidth with respect to the reference signal or the start position of the complete probing bandwidth (i.e. the probing bandwidth of the reference signal).
Specifically, the starting position of the partial detection bandwidth may be a starting position of the configuration bandwidth with respect to the reference signal or a starting position of a complete detection bandwidth; the end position of the partial probing bandwidth may be a start position of the configuration bandwidth with respect to the reference signal or a start position of one complete probing bandwidth; the probing window may be a starting position of the configuration bandwidth with respect to the reference signal or a starting position of one complete probing bandwidth.
Alternatively, the starting position of the reference signal configuration bandwidth may be subcarrier 0 (subcarrier 0 in common resource block 0) of the common resource block 0, or may be the lowest subcarrier position of the bandwidth part (BWP).
Optionally, in an embodiment of the present invention, the comb resource may include at least one enabling sub-resource.
It should be noted that, the comb resources are in the partial probing bandwidth, and each X (i.e., comb value) sub-resource includes one enable sub-resource, that is, can be performed once, in units of the bandwidth of the enable sub-resource.
For example, assuming a comb value of x=3, every 3 sub-resources may include one enabled sub-resource within the partial probe bandwidth.
Alternatively, for the above form two, the above-described enabled sub-resource bandwidth (i.e., the bandwidth of the enabled sub-resource) may be associated with at least one of: the subband bandwidth (b_subband) and the spreading factor (i.e., subband spreading factor) of the reference signal.
Alternatively, the above-mentioned enabled sub-resource bandwidth may be a product of a sub-band bandwidth of the reference signal and an expansion coefficient, even though the enabled sub-resource bandwidth=b_subband×beta.
It should be noted that, for the description of the subband bandwidth of the reference signal, reference may be made specifically to the detailed description of the subband bandwidth of the reference signal in the above embodiment; for a description of the expansion coefficient, reference may be specifically made to the detailed description of the expansion coefficient in the above embodiment to avoid repetition, which is not repeated here.
The following description will be made with reference to the example in which the SRS is used as the reference signal, and the above-described form two (in which the enabling signaling is in the comb indication mode) is exemplified.
Example 9: as shown in fig. 12, the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 2, slot offset=0, ns=1, r=1, and no frequency hopping occurs; and one full probe bandwidth b_full=48 RB, a partial probe bandwidth=24 RB, a subband bandwidth=6rb, a subband expansion coefficient=1, and one subband bandwidth=6rb; and the comb value is equal to 2 (i.e., comb size=2), and the comb offset value is equal to 0 (i.e., comb offset=0). At this time, the start position of the SRS partial sounding bandwidth is a start position corresponding to one complete SRS sounding bandwidth, and the enabling sequence is from small to large in frequency domain sequence.
Example 10: assuming that the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 2, slot offset=0, ns=1, r=1, and no frequency hopping is performed; and one full probe bandwidth b_full=48 RB, a partial probe bandwidth=24 RB, a subband bandwidth=6rb, a subband expansion coefficient=1, and one subband bandwidth=6rb; and the comb value is equal to 2 (i.e., comb size=2), and the comb offset value is equal to 0 (i.e., comb offset=0). At this time, as shown in fig. 13, the start position of the SRS partial sounding bandwidth is the start position with respect to one full SRS sounding bandwidth, and the start position of the sounding window is the start position with respect to one full SRS sounding bandwidth, sounding window bandwidth=42 RB, and the enabling order is in frequency domain order from small to large; as shown in fig. 14, the start position of the SRS partial sounding bandwidth is a start position with respect to the SRS configuration bandwidth, and the start position of the sounding window is a start position with respect to the SRS configuration bandwidth, and the order of enabling is in frequency domain order from small to large.
Example 11: as shown in fig. 15, the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 2, slot offset=0, ns=1, r=1, and no frequency hopping occurs; and one full probe bandwidth b_full=48 RB, a partial probe bandwidth=24 RB, a subband bandwidth=6rb, a subband expansion coefficient=1, and one subband bandwidth=6rb; and the comb value is equal to 2 (i.e., comb size=2), and the comb offset value is equal to 1 (i.e., comb offset=1). At this time, the start position of the SRS partial sounding bandwidth is a start position corresponding to one complete SRS sounding bandwidth, and the enabling sequence is from small to large in frequency domain sequence.
Example 12: as shown in fig. 16, the SRS resource is a periodic resource (i.e., periodic combSRS resource), the period is 1, nscomb=4, rcomb=comb1, and the frequency hopping groups include 1 continuous OFDM symbol; and one full probing bandwidth b_fullcomb=48 RB, partial probing bandwidth=comb 32RB, single hop bandwidth comb=comb 4RB, subband expansion coefficient=1, one subband bandwidth=4 RB; and the comb value is equal to 2 (i.e., comb size=2), and the offset value is equal to 0 (i.e., comb offset=0). At this time, the start position of the SRS partial sounding bandwidth is a start position corresponding to one complete SRS sounding bandwidth, and the enabling sequence is from small to large in frequency domain sequence.
Example 13: as shown in fig. 17, the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 1, ns=4, r=1, 4 hopping groups, and the hopping groups include 1 continuous OFDM symbol; and one complete probing bandwidth b_full=48 RB, partial probing bandwidth=comb 32RB, single frequency hopping bandwidth=comb 4RB, subband expansion coefficient=1, one subband bandwidth=4 RB; and the comb value is equal to 2 (i.e., comb size=2), and the comb offset value is equal to 0 (i.e., comb offset=0). At this time, the starting position of the SRS partial sounding bandwidth is a starting position corresponding to a complete SRS sounding bandwidth, and the enabling sequence of the UE may be a time domain sequence.
The embodiment of the invention provides a reference signal sending method, which can reduce the number of sub-resources for sending reference signals because UE can send reference signals only on the enabled sub-resources indicated by the enabled signaling, and can increase the energy of the reference signals sent on each sub-resource when the number of the sub-resources for sending the reference signals is reduced because the total energy of the reference signals sent by the UE is fixed, thereby improving the quality of the reference signals sent by the UE.
Optionally, in the embodiment of the present invention, after S202 described above, the method for sending a reference signal provided in the embodiment of the present invention may further include S204 described below.
S204, when the reference signal is sent in a frequency hopping mode, the UE sends other signals on the non-enabled sub-resource indicated by the enabled signaling.
In the embodiment of the invention, when the reference signal is sent in a frequency hopping mode, the UE can send other signals on the non-enabled sub-resource indicated by the enabled signaling, so that the utilization rate of the reference signal resource (namely the resource configured by the network equipment to the UE) can be improved, and the resource expense can be saved.
Optionally, in the embodiment of the present invention, after S202 described above, the reference signal sending method provided in the embodiment of the present invention may further include S205 described below.
S205, the UE does not send any signal on the non-enabled sub-resource indicated by the enabled signaling.
In the embodiment of the invention, when the reference signal is sent in a frequency hopping mode, the UE can not send any signal on the non-enabled sub-resource indicated by the enabled signaling, namely, the UE only sends the reference signal on the enabled sub-resource indicated by the enabled signaling, so that the quality of the reference signal sent by the UE can be improved.
Optionally, in the embodiment of the present invention, after S202 described above, the method for sending a reference signal provided in the embodiment of the present invention may further include S206 described below.
S206, when the reference signal is sent in a frequency hopping mode, the UE sends the reference signal on the enabled sub-resource indicated by the enabled signaling in advance according to the enabling sequence of the sub-resource indicated by the enabled signaling.
In the embodiment of the invention, under the condition that the reference signal is sent in a frequency hopping mode, the UE can sequentially promote the reference signal on the enabled sub-resource indicated by the enabled signaling according to the enabling sequence of the sub-resource indicated by the enabled signaling, so that the speed of sending the reference signal by the UE can be reduced, namely the speed of sending the reference signal by the UE can be increased.
Optionally, in the embodiment of the present invention, the manner in which the UE sends the reference signal on the enabled sub-resource indicated by the enabled signaling in advance may include the following two manners, namely, the first manner and the second manner. The two modes are specifically described below as examples.
Mode one: the UE may send the reference signal on the sub-resource that is available in turn on the earliest time domain among the sub-resources indicated by the enabled signaling, where the available sub-resources may include an enabled sub-resource and a non-enabled sub-resource.
That is, the reference signal transmitted in advance in the above-described mode one may be a full-advance transmission. The full advance transmission may indicate that all the time domain frequency hopping resources of the enabled reference signal occupy the time domain frequency hopping resources of the earliest available reference signal in sequence according to the enabled sequence, where the time domain transmission resources of the reference signal may include enabled frequency hopping resources and non-enabled frequency hopping resources.
The first embodiment will be exemplarily described below with reference to example 14.
Example 14: assuming that the enabling signaling is in a comb indication manner, as shown in (a) in fig. 18, the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 1, ns=4, and r=1, and the frequency hopping groups include 1 continuous OFDM symbol; and a complete probing bandwidth b_full=48 RB, a partial probing bandwidth=32 RB, a single frequency hopping bandwidth=4 RB, a subband expansion coefficient=1, and a subband bandwidth=4 RB; and the comb value is equal to 2 (i.e., comb size=2), and the comb offset value is equal to 0 (i.e., comb offset=0). The starting position of the SRS partial sounding bandwidth is relative to the starting position of a complete SRS sounding bandwidth, and the enabling sequence is time domain sequence. Then, when the UE transmits the reference signal on the sub-resource (including the enabled sub-resource and the disabled sub-resource) which is sequentially available on the earliest time domain among the sub-resources indicated by the enabled signaling, the UE may transmit the reference signal on the sub-resource as shown in (b) of fig. 18, so that the UE may increase the speed of transmitting the reference signal.
Mode two: the UE may send the reference signal on the sub-resource that is available in turn on the earliest time domain among the sub-resources indicated by the enabled signaling, where the available sub-resources include only non-enabled sub-resources.
That is, the reference signal transmitted in advance in the second embodiment may be partially transmitted in advance. The partial advance transmission indicates that on partial detection bandwidth, time domain frequency hopping resources of all the enabled reference signals sequentially occupy time domain frequency hopping resources of the earliest available reference signals according to the enabling sequence, wherein the time domain frequency hopping resources of the reference signals only comprise non-enabled frequency hopping resources.
The second embodiment is described below by way of example 15 and example 16.
Example 15: assuming that the enabling signaling is in a comb indication manner, as shown in (a) in fig. 19, the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 1, ns=4, and r=1, and the frequency hopping groups include 1 continuous OFDM symbol; and a complete probing bandwidth b_full=48 RB, a partial probing bandwidth=32 RB, a single frequency hopping bandwidth=4 RB, a subband expansion coefficient=1, and a subband bandwidth=4 RB; and the Comb value is equal to 2 (i.e., comb size=2), and the Comb offset value is equal to 0 (i.e., comb offset=0). The starting position of the SRS partial sounding bandwidth is relative to the starting position of a complete SRS sounding bandwidth, and the enabling sequence is time domain sequence. Then, when the UE transmits the reference signal on the sub-resource (including only the non-enabled sub-resource) which is sequentially available in the earliest time domain among the sub-resources indicated by the enabled signaling, the UE may transmit the reference signal on the sub-resource (the sub-resource filled in (b) of fig. 19) as shown in (b) of fig. 19, so that the UE may transmit the reference signal at a speed that may be increased to some extent.
Example 16: assuming that the enabling signaling is a bitmap (i.e., bitmap), as shown in (a) in fig. 20, the SRS resource is a periodic resource (i.e., periodic SRS resource), the period is 1, ns=4, r=1, and 4 hopping groups, where the hopping groups include 1 continuous OFDM symbol; and one complete probe bandwidth b_ ful =48 RB, single hop bandwidth=4rb, subband expansion coefficient=1, one subband bandwidth=4rb; and bitmap= 000101010100. The starting position of the SRS partial sounding bandwidth is relative to the starting position of a complete SRS sounding bandwidth, and the enabling sequence is time domain sequence. Then, when the UE transmits the reference signal on the sub-resource (including only the non-enabled sub-resource) which is sequentially available in the earliest time domain among the sub-resources indicated by the enabled signaling, the UE may transmit the reference signal on the sub-resource (the sub-resource filled in (b) of fig. 20) as shown in (b) of fig. 20, so that the UE may transmit the reference signal at a speed that is increased to some extent.

The specific determination may be determined according to actual use requirements, and the embodiment of the invention is not limited.

That is, after the network device configures the above-mentioned enabling signaling to the UE, the enabling signaling needs to be activated by the activation signaling, and then the enabling signaling can be validated.
