Referring to fig. 2, fig. 2 is a flowchart of an SRS resource indication method according to an embodiment of the present application, where the method is applied to a network side device. As shown in fig. 2, the method comprises the steps of:
Wherein the resource parameter information includes at least one of: the SRS time slot position, the SRS symbol starting position, the SRS symbol length, the SRS repetition factor and the SRS repetition number.
In the embodiment of the present application, the network side device may send the SRS resource parameter information to the terminal in a RRC signaling, a MAC CE, or a DCI. The terminal is configured with the resource parameter information of the SRS, for example, through an SRS configuration information element (SRS-Config IE) in RRC signaling. Optionally, the resource parameter information of the Sounding Reference Signal (SRS) may be parameters including a slot position of the SRS, a symbol start position of the SRS, a symbol length of the SRS, a repetition factor of the SRS, a repetition number of the SRS, and the like, and these parameters can determine a resource configuration of the SRS on at least two slots to indicate that the SRS can implement cross-slot repetition. The SRS may refer to an SRS resource or an SRS resource set.
It can be understood that, after configuring the SRS resource parameter information for the terminal, the network side device may send the SRS resource parameter information to the terminal, and then the terminal may determine the SRS resource configuration in at least two slots according to the SRS resource parameter information.
In the embodiment of the application, the resource parameter information of the SRS configured for the terminal by the network side device can be used to determine the resource configuration situation of the SRS supporting the inter-slot repetition, that is, the resource parameter information can indicate the time domain resource configuration situation of the SRS resource in at least two slots, so that the SRS can be transmitted in at least two slots, and the SRS transmission reliability is further improved.
Wherein the resource parameter information is configured in the SRS resource and/or is configured in the SRS resource set. Here, the resource parameter information may be configured for the SRS resource or may be configured for the SRS resource set. Optionally, when the resource parameter information is configured for the SRS resource, the resource parameter information may be configured through SRS-resource IE; when the resource parameter information is configured for the SRS resource set, the resource parameter information can be configured through SRS-resource set IE. For example, for the SRS resource of the periodic SRS and the semi-persistent SRS, the resource parameter information of the SRS is configured in the SRS resource; for aperiodic SRS resources, part of parameters in the SRS resource parameter information are configured in an SRS resource set, and the other part of parameters are configured in the SRS resources in the SRS resource set. For the specific implementation manner of the resource parameter information configured in the SRS resource and the specific implementation manner configured in the SRS resource set, reference may be made to the following detailed description.
In an embodiment of the present application, the resource parameter information includes at least one of: the SRS time slot position, the SRS symbol starting position, the SRS symbol length, the SRS repetition factor and the SRS repetition number. The configuration of the resource parameter information will be described in detail below by way of specific embodiments.
When the resource parameter information includes the slot position of the SRS, the slot position of the SRS resource is determined by at least one of the following modes:
at least one time slot time domain position corresponding to the SRS resource, wherein the at least one time slot time domain position is used for determining a first time slot and at least one other time slot position;
determining a first time slot and at least one configured time slot offset by a time slot time domain position corresponding to the SRS resource, wherein the at least one configured time slot offset is used for determining the rest at least one time slot position;
and determining a first time slot by using a time domain position of a time slot corresponding to the SRS resource, and configuring at least one symbol offset, wherein the at least one symbol offset is used for determining at least one rest time slot position.
Note that, the slot position of the SRS resource is arranged in the SRS resource.
In one implementation, the slot position of the SRS resource may be determined by configuring at least one slot position of the SRS resource, where the at least one slot time domain position is used to determine the first slot and the remaining at least one slot time domain position.
It should be noted that the at least one time slot offset is a time slot difference between a time domain position of a next time slot and a time domain position of a previous time slot; or the at least one time slot offset is a time slot difference between a time slot time domain position of a following time slot and a time slot time domain position of a first time slot; or a time slot difference between a time slot time domain position of the following time slot offset and a time slot time domain position of Downlink Control Information (DCI) for triggering the SRS resource in the aperiodic SRS resource set.
In this application, for periodic and semi-persistent SRS resources, the slot time domain position of the first slot of the SRS resource may be determined based on a configured periodic slot offset parameter, and each SRS resource may be a separately configured periodic slot offset parameter. For example, for periodic and semi-persistent SRS resources, a plurality of periodic slot offset parameters may be configured, based on which slot positions of the first slot and the remaining slots are determined. The periodic slot offset parameter is used to indicate a period and a slot offset within the period, and optionally, the plurality of periodic slot offset parameters need to be guaranteed to have the same period, and the slot offsets (slot offsets) are different.
For an aperiodic SRS resource, a slot time domain position of a first slot of the SRS resource may be determined based on a slot offset configured in the SRS resource set and/or a slot offset configured for the SRS resource in the SRS resource set, for example, no slot offset is configured or configured in the SRS resource set and is not valid, and only the slot offset configured in the SRS resource is valid; or, a time slot offset configured in the SRS resource set and/or at least one time slot offset configured in the SRS resource set may be determined, and a time slot time domain position of the SRS resource needs to be determined by triggering at least one of a receiving time slot position of downlink control information DCI of the SRS resource set, the time slot offset in the SRS resource set, and the time slot position of the SRS resource; in this case, the slot offset within the set of SRS resources and the slot offset within the SRS resources may be defined to be inconsistent, e.g., the slot offset within the set of SRS resources may be defined to be in effect on the uplink slot and the slot offset within the SRS resources may be defined to be in effect on all slots.
At least one slot position of the SRS resource includes: a time domain position of at least one time slot corresponding to the SRS resource; or, the time domain position of the first time slot corresponding to the SRS resource, and the position of the remaining at least one time slot are determined by a preset method, for example, a next uplink time slot of the first time slot. Wherein, the preset mode is as follows: the position of the latter time slot is separated from the position of the former time slot by a preset time length or a preset interval value. The preset value may be predefined in a protocol, and there may be a plurality of preset values, where one preset value is associated with one timeslot position. The preset duration or preset value may include: a plurality of slots, a plurality of symbols, etc. For example, if the default value associated with the second time slot is 2, the time slot position of the second time slot may be the time slot position of the first time slot plus 2 time slots, and if the default value associated with the third time slot is 3, the time slot position of the third time slot may be the time slot position of the second time slot plus 3 time slots, and so on. That is, a preset value may be predefined in the protocol for each time slot. Alternatively, the preset value may be only one predetermined value predefined in the protocol, and the preset value is applied to the determination of the positions of the other time slots except the first time slot, for example, the time slot position of the second time slot is the time slot position of the first time slot plus 2 time slots, the time slot position of the third time slot is the time slot position of the second time slot plus 2 time slots, and so on.
In another implementation, the slot position of the SRS resource may be determined by configuring one slot time domain position of the SRS resource to determine a first slot and configuring at least one slot offset to determine at least one remaining slot position. The at least one configured slot offset may be used to indicate a slot difference, where the slot difference may be defined as a difference between a time domain position of a subsequent slot and a time domain position of a previous slot, or the slot difference may also be defined as a difference between a time domain position of a subsequent slot and a time domain position of a first slot. In this embodiment, the at least one timeslot offset is configured by a network side device, and the preset value in the above embodiment is predefined in a protocol.
In another implementation, the slot position of the SRS resource may be determined by configuring one slot time domain position of the SRS resource to determine a first slot and configuring at least one symbol offset for determining the remaining at least one slot position. Wherein configuring the at least one symbol offset may be for indicating a symbol difference. The at least one symbol offset is a symbol distance difference between a time domain position of a next time slot and a time domain position of a previous time slot; or, the at least one symbol offset is a symbol distance difference between a time domain position of a subsequent time slot and a time domain position of a first time slot; or, the at least one symbol offset is a symbol distance difference between a subsequent time slot time domain position and a time slot time domain position at which DCI for triggering SRS resources in the aperiodic SRS resource set is received.
It should be noted that, the preset value, the at least one symbol offset, and the at least one slot offset in the above implementation may be applied to all slots, that is, all slots need to be considered when calculating the slot difference and the symbol difference; or only act on the uplink time slot and/or the special time slot, which may refer to both uplink and downlink time slots or variable time slots.
The at least one slot offset and the at least one symbol offset may be applied to all time domain slot position determinations except for the first slot time domain position indication when only one slot offset and one symbol offset are configured, or one slot difference and one symbol difference may be applied to at least one time domain slot position determination except for the first slot time domain position indication.
In this application, when the SRS resource parameter information is configured in an SRS resource set, the SRS slot position satisfies at least one of the following conditions:
the SRS resource set corresponds to a plurality of time slot offsets, the number of the time slot offsets is equal to the number of the SRS resources in the SRS resource set, and each SRS resource in the SRS resource set is associated with one time slot offset;
an SRS resource set corresponds to a plurality of slot offsets, each SRS resource in the SRS resource set is associated with at least one slot offset, and partial SRSs in the SRS resource set are associated with at least two slot offsets;
an SRS resource set corresponds to a plurality of slot offsets and a plurality of symbol offsets, each SRS resource in the SRS resource set is associated with one slot offset, and each SRS resource in at least part of the SRS resources in the SRS resource set is associated with at least one symbol offset;
the SRS resource set corresponds to a time slot offset, and when at least two SRS resources are configured in the SRS resource set, only one SRS resource can realize cross-slot repetition, and the rest SRS resources are transmitted on a first time slot determined by the time slot offset.
Optionally, for an aperiodic SRS, under the condition that a plurality of slot offsets are configured through an SRS resource set, where the number of the slot offsets is equal to the number of SRS resources in the SRS resource set, and each SRS resource in the SRS resource set is associated with one slot offset one by one, if a target SRS resource in the SRS resource set needs to implement slot-crossing repetition, slot positions of remaining SRS resources in the SRS resource set are determined by at least one of: the preset mode, the time slot difference and the symbol difference; the preset mode is as follows: the latter slot position is separated from the former slot position by a preset time length.
The time slot difference may be a time slot difference between a time domain position of a next time slot and a time domain position of a previous time slot; or the time slot difference is the time slot difference value of the time slot time domain position of the following time slot and the time slot time domain position of the first time slot; or the time slot difference is a time slot difference between a subsequent time slot time domain position and a time slot time domain position of receiving the DCI for triggering the SRS resource in the aperiodic SRS resource set.
The symbol difference may be a symbol distance difference between a time domain position of a next time slot and a time domain position of a previous time slot; or the symbol difference is a symbol distance difference value between a time domain position of a subsequent time slot and a time domain position of a first time slot; or the symbol difference is a symbol distance difference between a time domain position of a subsequent time slot and a time domain position of a time slot for receiving DCI for triggering SRS resources in the aperiodic SRS resource set.
It should be noted that the target SRS resource refers to any one or more SRS resources in the SRS resource set that need to implement the cross-slot repetition. It can be understood that the slot position of the target SRS resource can be determined by the associated slot offset, and the slot positions of the remaining SRS resources that do not need to implement the cross-slot repetition can be determined by a slot difference, a symbol difference, or a preset manner. The preset manner may refer to the detailed description in the above embodiments, and is not described herein again.
Optionally, for the aperiodic SRS, under the condition that a plurality of slot offsets are configured through an SRS resource set, and at least one slot offset is associated with each SRS resource in the SRS resource set, a slot position of a target SRS resource in the SRS resource set, which is associated with the plurality of slot offsets and needs to implement cross-slot repetition, may be determined by a slot position of the SRS resource and/or a symbol start position of the SRS resource.
For example, in one embodiment, if each SRS resource is associated with multiple slot offsets and the target SRS resource needs to implement slot-crossing repetition, the slot position of the target SRS resource is determined according to the slot position of the SRS resource and/or the symbol start position of the SRS resource.
The target SRS resource refers to any one or more SRS resources needing to realize cross-slot repetition in an SRS resource set; the determination of the slot position of the SRS resource may be as described in the foregoing embodiment, and the symbol start position of the SRS resource may be: the SRS resource may be a plurality of symbol start positions configured to respectively determine symbol start positions of a first slot and a subsequent slot; alternatively, the SRS resource may be configured with a symbol start position and at least one symbol offset, and the symbol position of the subsequent slot is determined by the configured at least one symbol offset. It can be understood that each SRS resource in the SRS resource set is associated with at least one slot offset, and if an SRS resource needs to be transmitted at a slot position of the associated at least one slot offset, a symbol position may be determined in the preset manner; alternatively, the SRS resource may be configured with a symbol start position, the symbol start positions may be in one-to-one correspondence with the slot offsets, and the symbol position may be determined by the corresponding slot offset.
Or, in another embodiment, if a part of SRS resources in the SRS resource set are associated with one slot offset, and the remaining SRS resources are associated with multiple slot offsets, and a target SRS resource associated with multiple slot offsets needs to implement slot-crossing repetition, the slot position of the target SRS resource is determined by the slot position of the SRS resource and/or the symbol start position of the SRS resource. That is, the target SRS resource refers to an SRS resource that needs to implement cross-slot repetition, and the target SRS resource may be at least one of SRS resources associated with a plurality of slot offsets. The time slot position of the target SRS resource is determined by the time slot position of the SRS resource and/or the symbol start position of the SRS resource, which may specifically refer to the above description, and is not described herein again.
It should be noted that, for an aperiodic SRS, under the condition that a plurality of slot offsets are configured through an SRS resource set, and each SRS resource in the SRS resource set is associated with at least one slot offset, if each SRS resource is associated with only one slot offset, it can be considered that the SRS resource is not repeated across slots; or, if each SRS resource is associated with a slot offset, the SRS resource may be directly indicated by signaling or implicitly indicated by signaling to enable the inter-slot repetition, where the first slot is determined by the slot offset associated with the SRS resource, and the subsequent slots are determined by the preset method.
Optionally, for the aperiodic SRS, under the condition that a plurality of slot offsets and a plurality of symbol offsets are configured through an SRS resource set, one slot offset is associated with each SRS resource in the SRS resource set, and at least one symbol offset is associated with each SRS resource in at least part of SRS resources in the SRS resource set, if a target SRS resource is not associated with a symbol offset and it is necessary to implement slot-crossing repetition, a first slot is determined by the associated slot offset, and the remaining slots are determined by the preset method. Wherein, the target SRS resource needs to realize the cross-slot offset may be directly indicated or implicitly indicated through signaling.
Or, if the target SRS resource is associated with at least one symbol offset and needs to implement the inter-slot repetition, the target SRS resource is transmitted on a slot determined according to the slot offset and the symbol offset.
Optionally, for the aperiodic SRS, a time slot offset is configured through an SRS resource set, and at least two SRS resources are configured in the SRS resource set, where only one SRS resource can implement cross-slot repetition, and the remaining SRS resources are transmitted in a first time slot determined according to the time slot offset, and if it is required to implement the cross-slot repetition, the target SRS resource is transmitted in the first time slot, and the time slot position of a subsequent time slot is determined in the preset manner. For example, the slot position of the second slot is the slot position of the first slot plus a preset value, and the slot position of the third slot is the slot position of the second slot plus a preset value, so as to determine the slot positions of the rest slots.
Or, if the target SRS resource which is repeated across the time slots needs to be transmitted without the first time slot, determining the positions of all the time slots of the target SRS resource through the preset mode. That is to say, the SRS resource set is configured with only one slot offset, and all slot positions of the target SRS resource to be repeated across slots are determined in the preset manner, for example, the slot position of the first slot of the target SRS resource is determined by the configured slot offset, the slot position of the second slot is the slot position of the first slot plus a preset value, and the rest slot positions of the target SRS resource are determined accordingly.
Additionally, for an aperiodic SRS, where the aperiodic SRS is in a cross-slot repetition, a slot offset may be effective at least one of:
any time slot;
an uplink time slot;
the special time slots comprise an uplink time slot and a downlink time slot;
a time slot available for uplink transmission;
an active time slot.
The effective time slot is defined to be capable of completing transmission of all resource configuration information in an SRS resource set in a plurality of determined time slots; the number of the multiple determined time slots is determined by the number of the time slots needed by each SRS resource in the SRS resource set, and the time domain positions of the time slots of the multiple determined time slots are determined by the position of the time slot where each SRS resource in the SRS resource set is located.
In this embodiment of the present application, in a case that the resource parameter information includes a symbol start position of an SRS resource, the symbol start position of the SRS resource is determined by at least one of:
a symbol start position of the SRS resource configuration;
a plurality of symbol starting positions of the SRS resource configuration;
a symbol start position and at least one symbol offset of the configuration of SRS resources.
The initial symbol position of the SRS resource configuration is used to determine the initial symbol position sent by the SRS in the first time slot, and the initial symbol positions of the other time slots are determined by a preset time length, where the preset time length is the initial first symbol position supported in the resource configuration information, or the preset time length is the same as the initial symbol position of the first time slot.
And under the condition that the SRS resource is configured with a plurality of symbol starting positions, the plurality of symbol starting positions are used for determining the starting position of the first time slot and the symbol starting positions of the rest time slots.
In the case of one symbol start position and at least one symbol offset of the SRS resource configuration, the at least one symbol offset is used to determine a symbol position in a subsequent slot, and the symbol start position of the subsequent slot may be determined based on the symbol start position of the first slot and the configured symbol offset.
In this embodiment of the present application, when the resource parameter information includes a symbol length of an SRS resource, the SRS resource symbol length is determined by at least one of:
one symbol length of the SRS resource;
a plurality of symbol lengths of the SRS resources, the plurality of symbol lengths being used to determine symbol lengths for SRS transmissions in a first slot and remaining subsequent slots.
If the SRS resource symbol length includes a symbol length, for example, the symbol length may be the length of the SRS transmission in the first slot, and the length of the SRS transmission in the first slot may be equal to the symbol starting position of the slot to the last symbol position of the slot.
Optionally, in a case that the SRS resource is configured with one symbol length, the one symbol length of the SRS resource may be determined as follows:
if the symbol length is less than or equal to the symbol starting position available for SRS transmission in a first slot to the last symbol position of the first slot, the symbol length of the SRS in the first slot is the symbol length;
if the symbol length is greater than the symbol starting position available for SRS transmission in the first slot to the last symbol position of the first slot, the symbol length of SRS in the first slot is equal to the symbol starting position available for SRS transmission in the first slot to the last symbol position of the Nth slot;
when the symbol length is greater than the symbol starting position available for SRS transmission in the first slot to the last symbol position of the first slot, if the target symbol length is greater than the symbol starting position available for SRS transmission in the Nth slot to the last symbol position of the Nth slot, the symbol length of SRS in the Nth slot is equal to the symbol starting position available for SRS transmission in the Nth slot to the last symbol position of the Nth slot;
if the target symbol length is less than or equal to the symbol starting position available for SRS transmission in the Nth time slot to the last symbol position of the Nth time slot, the symbol length of the SRS in the Nth time slot is the residual symbol length;
wherein N is a positive integer greater than 1, and the target symbol length is a symbol length from an nth slot to a last slot of the SRS resource.
The SRS resource is configured with only one symbol length, and if N is equal to 1, if the configured symbol length is less than or equal to a symbol start position available for SRS transmission in the first slot to a last symbol position of the first slot, the symbol length of the SRS in the first slot is the one symbol length; if the configured symbol length is greater than the symbol start position available for SRS transmission in the first slot to the last symbol position of the first slot, the symbol length of the SRS in the first slot is from the symbol start position available for SRS transmission in the first slot to the last symbol position of the first slot.
If N is a positive integer greater than 1, the symbol length of the first slot is determined based on the above method, and if the one symbol length is greater than the symbol start position available for SRS transmission in the first slot to the last symbol position of the first slot, the symbol lengths for the second slot and the following slots may be determined based on the following method: assuming that N is greater than 2, the target symbol length is the symbol length from the second slot to the last slot of the SRS resource; if the target symbol length is greater than the symbol start position available for SRS transmission in the second slot to the last symbol position of the slot, the symbol length transmitted by the SRS in the second slot is equal to the symbol start position available for SRS transmission in the slot to the last symbol position of the slot, and then the determination of the symbol length of the subsequent slot needs to be considered; if the target symbol length is less than or equal to the symbol start position available for SRS transmission in the second slot to the last symbol position of the slot, the symbol length transmitted by the SRS in the second slot is equal to the target symbol length, and it can be considered that there is no subsequent symbol length. Based on the same principle, if the symbol length of the subsequent slot needs to be considered, the symbol length of the subsequent slot may be determined according to the above-mentioned manner, that is, N is 3, N is 4, and the like, so as to determine the symbol length of the subsequent slot.
In case that the resource parameter information of the SRS includes a repetition factor, the resource parameter information may include at least one of:
a repetition factor, the repetition factor being less than or equal to a total length of symbols configured within the SRS resources;
a plurality of repetition factors.
Wherein, in case the resource parameter information comprises a plurality of repetition factors, each repetition factor satisfies at least one of:
including two symbol lengths and/or symbol start positions;
the Nth repetition factor is less than or equal to the Nth symbol length, and N is a positive integer greater than or equal to 1;
and under the condition that the aperiodic SRS frequency hopping is started, the SRS can complete frequency hopping in the determined at least two time slots.
That is, when the SRS resource parameter information is configured with a plurality of repetition factors, each repetition factor needs to be configured with two symbol lengths and/or symbol start positions at the same time. Further, for the plurality of repetition factors, it may be that the first repetition factor is smaller than the first symbol length and the second repetition factor is smaller than the second symbol length, thereby defining the remaining repetition factors. In addition, in the case of frequency hopping for an aperiodic SRS, a plurality of repetition factors are configured to enable the SRS to complete frequency hopping within a determined plurality of slots.
It should be noted that, when the hopping pair includes at least 2 symbols, the terminal does not expect the hopping pair used for hopping in one SRS resource to be transmitted on different time slots.
For better understanding, the following description will be made on the frequency hopping based on the specification of the protocol in the related art.
In the related art, Frequency hopping is configured in SRS resources, but not configured repeatedly, and each port of the SRS resources is mapped to a different set of subcarriers on each Orthogonal Frequency Division Multiplexing (OFDM) symbol in each slot and between slots, that is, Frequency domain resources on each OFDM symbol are different;
R=1;
the number of hopping pairs is equal to Ns/R;
the number of OFDM symbols in a hopping pair is equal to 1;
frequency hopping is carried out according to Bsrs, Csrs, bhop and a frequency hopping formula;
comb values of different subcarrier sets are the same;
for Ns ═ 1, 1 OFDM symbol is used for SRS transmission in each slot, and frequency hopping is required between slots, that is, between OFDM symbols, that is, frequency domain resources are different, that is, inter-slot hopping is required.
For Ns 2/4, 1/2 OFDM symbols are used for SRS transmission in each slot, frequency hopping is required in the slot, and one hopping pair includes 1 OFDM symbol, and frequency hopping is also required between slots at this time, that is, each OFDM symbol hops, that is, intra-slot hopping.
Or, the SRS resource is configured with frequency hopping and is configured repeatedly, when Ns is 4 and R is 2, in each slot, each port of the SRS resource is mapped to the same subcarrier set in each hop-pair, and different subcarrier sets exist between hop groups;
Ns=4,R=2;
the number of hopping pairs is equal to Ns/R;
the number of OFDM symbols in the hopping pair is equal to R;
the number of the frequency hopping pairs represents the frequency hopping times in the slot;
not hopping within a group, namely different OFDM symbols within a hopping pair occupy the same frequency domain resource;
frequency hopping between groups, i.e. different frequency domain resources are occupied between hopping pairs.
When frequency hopping is configured, specifically:
it should be noted that the non-periodicity only limits the subbands that need to be configured to have equal bandwidth, but actually, for example, 4 symbols, can detect the integrity only by two symbols, and the latter two symbols are repeated, and the protocol also supports this configuration.
Aperiodic SRS, which supports only intra-slot hopping within one Bandwidth Part (BWP):
Ns=1,R=1,
not hopping;
because an aperiodic resource only occupies one resource, one symbol cannot realize frequency hopping.
Ns 2, R1, aperiodic SRS resource of 2 adjacent symbols;
intra-slot frequency hopping;
in a BWP, the sounding bandwidth is divided into 2 sub-bands with equal bandwidth, and the complete frequency hopping bandwidth is probed over 2 OFDM symbols.
Ns 4, R1, aperiodic SRS resource of 4 adjacent symbols;
intra-slot frequency hopping;
in a BWP, the sounding bandwidth is divided into 4 equal sub-bands, and the complete hopping bandwidth is detected over 4 OFDM symbols.
Ns 2, R2, aperiodic SRS resources of 2 adjacent symbols;
not hopping;
occupying the same frequency domain resources.
Ns 4, R2, aperiodic SRS resources of 4 adjacent symbols;
intra-slot frequency hopping;
in a BWP, dividing a sounding bandwidth into 2 sub-bands with equal bandwidth, and detecting the complete frequency hopping bandwidth on 2 frequency hopping pairs.
Ns 4, R4, aperiodic SRS resource of 4 adjacent symbols;
not hopping;
occupying the same frequency domain resources.
For periodic/semi-persistent SRS, intra-slot and inter-slot hopping is supported within one BWP:
Ns=1,R=1;
inter-slot hopping.
Ns 2, R1, SRS resources of 2 adjacent symbols;
intra-slot and inter-slot;
frequency hopping is performed on the SRS resource in units of 1 OFDM symbol.
Ns 4, R1, SRS resources of 4 adjacent symbols;
intra-slot and inter-slot;
frequency hopping is performed on the SRS resource in units of 1 OFDM symbol.
Ns 2, R2, SRS resources of 2 adjacent symbols;
inter-slot frequency hopping;
in R adjacent OFDM symbols(s) of the SRS resource of each slot, each antenna port of the SRS resource is mapped to the same set of subcarriers, i.e. the SRS resource occupies the same frequency domain resource on different OFDM symbols within each slot.
Ns 4, R2, SRS resources of 4 adjacent symbols;
intra-slot and inter-slot;
each antenna port of the SRS resource is mapped onto a different set of subcarriers between two pairs of adjacent OFDM symbols(s) of the SRS resource in each slot, i.e., between a hopping pair, and each antenna port of the SRS resource is mapped onto the same set of subcarriers in each pair of adjacent OFDM symbols(s) of the SRS resource in each slot, i.e., within a hopping pair.
Ns 4, R4, SRS resources of 4 adjacent symbols;
inter-slot frequency hopping;
in R adjacent OFDM symbols(s) of the SRS resource of each slot, each antenna port of the SRS resource is mapped to the same subcarrier set, that is, the SRS resource occupies the same frequency domain resource on different OFDM symbols in each slot, and the SRS resources of N symbols occupy the same symbol position in each slot.
And in the case that the resource parameter information of the SRS comprises the repetition times, the repetition times are used for indicating the repetition times of the SRS on the first time slot on other time slots. Wherein, in case of repetition of the SRS resource, the SRS resource satisfies at least one of:
time domain time slot positions are different;
the frequency domain locations in the case of frequency hopping are different or the same.
That is, the SRS resource repetition may be only time domain slot position different, and/or frequency domain position different or the same at frequency hopping. For example, the number of repetitions is 3, inter-slot frequency hopping exists, and the SRS resources of the second slot and the third slot are identical to the frequency domain of the first slot; in the next period, the first time slot undergoes inter-time-slot frequency hopping, and then the frequency domain positions of the SRS resources of the second time slot and the third time slot of the next period are the same as the frequency domain position of the SRS resource of the first time slot for transmitting the frequency hopping.
For example, the SRS resource is configured with only one symbol number, one repetition factor, one slot time domain position, and one slot difference, where the repetition number is 3, which means that the SRS in the first slot is determined according to the configured symbol number, repetition factor, slot time domain position, and slot difference, and is transmitted in the first slot, and according to the repetition number being 3, the SRS that is exactly the same as the SRS transmitted in the first slot is transmitted in the second slot and the third slot, and the slot time domain positions of the second slot and the third slot may be determined according to the slot time domain position and slot difference of the first slot. Or, if 2 timeslot differences are configured in this embodiment, the timeslot time domain positions of the second timeslot and the third timeslot may be determined according to the timeslot time domain position of the first timeslot and the associated timeslot difference.
In the embodiment of the application, the number of time slots required for the SRS resource to perform the inter-slot repetition is determined by at least one of the following:
the number of time slot time domain positions of SRS resource configuration;
the number of slot offsets of the SRS resource configuration for indicating the time domain difference;
a number of symbol offsets of the SRS resource configuration to indicate a symbol difference;
a plurality of symbol start positions;
the number of symbol offsets;
a plurality of symbol lengths;
the number of repetition factors;
the number of repetitions;
number of repetitions.
For example, the number of time slots required for the SRS resource to perform the cross-slot repetition is equal to the number of time-domain positions of the time slots configured by the SRS resource; or equal to the number of slot offsets used to indicate the time domain difference plus 1; or equal to the number of symbol offsets used to indicate the symbol difference plus 1; or equal to the number of configured symbol offsets plus 1; or a number equal to the configured symbol length; or equal to the number of configured repetition factors; or equal to the number of configured repetitions; and the like.
It should be noted that the network side device may directly indicate or implicitly indicate, through signaling, that the SRS needs to implement the cross-slot repetition. Wherein the implicit indication comprises at least one of:
configuring at least two time domain positions;
configuring at least two symbol positions;
configuring at least two symbol lengths;
configuring a symbol length, wherein the symbol length is greater than the length from a symbol starting position of a first time slot for sending an SRS to a last symbol position of the first time slot;
configuring at least two repetition factors;
the number of repetitions of the configuration;
the repetition times of the configuration are greater than the preset value.
It should be noted that the at least two time domain positions may be determined according to at least one of the number of time slot time domain positions of the SRS configuration, the number of time slot offsets used for indicating the time domain difference, and the number of symbol offsets used for indicating the symbol difference. For example, the at least two time domain positions may be determined according to at least two configured time slot time domain positions, and the at least two time slot time domain positions may include at least two period offset parameters, or one period offset parameter and at least one time slot offset, or one period offset parameter and at least one symbol offset, or at least two time slot offsets, or one time slot offset and at least one symbol offset.
The at least two symbol positions may be determined according to a number of symbol start positions or symbol offsets. For example, a plurality of symbol start positions are respectively used to determine the symbol start position of the first slot and the symbol start position of the subsequent slot, or the symbol start position of the subsequent slot may be determined according to the symbol offset. The determination of the symbol start position and the symbol offset may be as described with reference to the above embodiments.
In addition, the determination of the symbol length, the repetition factor and the repetition number may refer to the description in the above embodiments, and will not be described herein again. In the embodiment of the present application, based on the configuration information included in the implicit indication, it can be indicated that the SRS can implement slot-crossing repetition, so as to improve the reliability of the SRS.
In an embodiment of the present application, when the SRS is a periodic SRS or a semi-persistent SRS, and the SRS hops, the method further includes:
frequency domain location information of the SRS resources is determined based on the SRS counter.
It should be noted that the determining of the frequency domain location information of the SRS resource based on the SRS counter occurs only when the SRS implements the inter-slot repetition.
Optionally, in a case that the SRS resource only includes one symbol number Ns and a repetition factor R, the SRS counter is determined by at least one of:

In this case, the frequency domain locations of the different hopping pairs within the SRS resource are calculated based on the above formula.
Or, in another embodiment, if the SRS resource includes only one repetition factor, when a plurality of slots of the SRS resource configured to be repeated across slots by the network side device are allowed to be in different SFNs,
