Background
Third generation partnership project (3GPP) in the discussion on new air interface multiple input multiple output measurement reference signal (NR MIMO SRS) configurations, it has been determined that measurement reference signal resources (sets) can be configured into three types: periodic SRS (P-SRS), Aperiodic SRS (AP-SRS), and Semi-persistent SRS (SP-SRS). The time domain property configurations of all SRS resources contained in one SRS resource set are consistent, that is, the types of the configurations are consistent. The slot position offset (slotoffset) of the P-SRS and the SP-SRS is configured in units of SRS resource, and the slotoffset of the AP-SRS is configured in units of SRS resource set.
In addition, it was determined at the 3GPP RAN AH conference to multiplex a new air interface NR measurement reference signal as a C L I measurement reference signal, i.e. SRS can be multiplexed as a terminal-to-terminal (UE-UE) C L I measurement reference signal.
In order to solve the cross link interference measurement under the condition of a flexible frame structure and reduce the information interaction amount among base stations, for the scheme of multiplexing a P-SRS and an SP-SRS as a C L I measurement reference signal, the C L I measurement period among users can be reduced by indicating the joint transceiving state of each SRS resource corresponding symbol of the C L I measurement reference signal in an SRS resource set configuration transmission period through a bitmap (bitmap) of Radio Resource Control (RRC) signaling, and for multiplexing the AP-SRS, the C L I measurement reference signal joint transceiving is realized, and an applicable configuration scheme does not exist, so that the cross link interference measurement under the condition of the flexible frame structure is solved and the information interaction amount among the base stations is reduced.

Example one
An embodiment of the present invention provides a method for configuring a cross link interference measurement reference signal, where the method may be applied to a network side (a base station side), and a flow of steps of the method may be as shown in fig. 1, where the method includes:
step 101, configuring an aperiodic SRS resource set.
In this step, when it is determined that the terminal or the terminal group needs to perform the cross link interference measurement, an aperiodic SRS resource set may be configured for the terminal or the terminal group. In one possible implementation, the aperiodic SRS resource set may be configured for a terminal or group of terminals through RRC signaling.
It should be noted that, when configuring the aperiodic SRS resource set for the terminal or the terminal group, the aperiodic SRS resource set configured for the terminal or the terminal group may be interacted with other base stations, so as to implement the measurement reference signal configuration information interaction between the base stations.
In one possible implementation manner, configuring an aperiodic SRS resource set for a terminal or a terminal group includes: the quantity of the aperiodic SRS resource sets configured for the terminal or the terminal group is consistent with that of the aperiodic SRS resource sets configured for the corresponding terminal or the terminal group by other base stations, and the time-frequency resource configuration and the time slot offset value of the aperiodic SRS resource sets with the same SRS resource set identification ID are consistent in one time slot. Therefore, the one-to-one correspondence relationship of the aperiodic SRS resource sets between the terminals (groups) can be formed during the joint transceiving, and the smooth realization of the joint transceiving is further ensured.
It should be further noted that configuring the aperiodic SRS resource set for the terminal or the terminal group may further include: the functionality of the aperiodic SRS resource set is configured as cross-link interference measurements through higher layer RRC signaling.
That is, in the process of configuring the aperiodic SRS resource set for the terminal or the terminal group, the function of the aperiodic SRS resource set may be configured as cross link interference measurement through high layer RRC signaling, and after the function configuration, the specific configuration of the number of the aperiodic SRS resource set, the slot position, and the like may be performed for the terminal or the terminal group.
Step 102, layer one signaling is sent.
After configuring the aperiodic SRS resource set for the terminal or the terminal group, in this embodiment, the terminal or the terminal group may be instructed to receive or transmit the C L I sounding reference signal on the configured aperiodic SRS resource set through layer one signaling, so as to implement joint transceiving of the aperiodic C L I sounding reference signal.
In this step, layer one signaling may be sent, which is used to instruct the terminal or the terminal group to receive or send C L I sounding reference signals on the configured set of aperiodic SRS resources.
The layer one (L eye 1) signaling refers to physical layer signaling, including DCI primarily used to indicate physical layer control information.
That is, in this embodiment, a layer-one signaling indication mode is adopted to implement joint transceiving of aperiodic C L I sounding reference signals, instead of a polling mode, the C L I sounding reference signals are transceived, so that the amount of information interaction between base stations can be effectively reduced compared to the polling mode.
In one possible implementation, the layer one signaling may include a DCI SRS request field whose value is used to instruct the terminal or the terminal group to receive or transmit the C L I sounding reference signal on the configured aperiodic SRS resource set.
If the DCI SRS request field value indicates that the terminal or the terminal group receives or transmits the C L I SRS resource set on the configured aperiodic SRS resource set in this step, configuring the aperiodic SRS resource set for the terminal or the terminal group in step 101 may include:
the aperiodicSRS-resource trigger state values corresponding to the SRS resource sets configured for the terminal or the terminal group and used for sending the C L I measurement reference signal are the same, and the aperiodicSRS-resource trigger state values corresponding to the SRS resource sets configured for the terminal or the terminal group and used for receiving the C L I measurement reference signal are the same and are different from the aperiodicSRS-resource trigger state values corresponding to the SRS resource sets used for sending the C L I measurement reference signal;
wherein, a one-to-one correspondence relationship is formed between one aperiodic SRS-resource trigger state value and one DCI SRS requestfield value.
For example, if the aperiodic SRS resource trigger state value corresponding to each SRS resource set configured for a terminal or a terminal group for transmitting a C L I sounding reference signal is 1, and the aperiodic SRS resource trigger state value corresponding to each SRS resource set configured for a terminal or a terminal group for receiving a C L I sounding reference signal is 2, the values corresponding to the DCI SRS request field may be set to, but are not limited to, 01 and 10, respectively.
When the DCI SRS request field is 01, an SRS resource set with an aperiodic SRS resource trigger state value of 1 may be triggered to transmit a C L I sounding reference signal, and when the DCI SRS request field is 10, an SRS resource set with an aperiodic SRS resource trigger state value of 2 may be triggered to receive a C L I sounding reference signal.
In one possible implementation, whether DCI SRS request field is used to trigger aperiodic SRS resource set transmission or reception of C L I sounding reference signals may also be specified, for example, but not limited to, by any one of the following two ways:
in a first mode, the DCI SRS request field adopts an extension format, and the extension format includes an indicator bit for indicating whether the DCI SRS request field is used to trigger an aperiodic SRS resource set to transmit or receive a C L I sounding reference signal.
The first bit of the DCI SRS request field may be used to indicate whether the DCI SRS request field is used to trigger an aperiodic SRS resource set transmission or reception of a C L I measurement reference signal.
When the first bit value is 1, the DCI SRS request field may be used to trigger the aperiodic SRS resource set to transmit or receive the C L I sounding reference signal.
If the DCI SRS request field adopts a 3-bit (bit) extension format, when an aperiodicssrs-resource trigger state value corresponding to each SRS resource set configured for a terminal or a terminal group and used for transmitting a C L I sounding reference signal is 1, the corresponding DCI SRS request field value may be but is not limited to be set to 101, when an aperiodicssrs-resource trigger state value corresponding to each SRS resource set configured for a terminal or a terminal group and used for transmitting a C L I sounding reference signal is 2, the corresponding DCI SRS request field value may be but is not limited to be set to 110, and when an aperiodic resource trigger state value corresponding to each SRS resource set configured for a terminal or a terminal group and used for transmitting a C L I sounding reference signal is 3, the corresponding DCI request field value may be but is not limited to be set to SRS 111.
And adding a high-layer RRC signaling in the DCI SRS request field, wherein the high-layer RRC signaling is used for indicating whether the DCISRS request field is used for triggering the sending or receiving of the C L I measurement reference signals of the aperiodic SRS resource set.
For example, the value of the C L I-config parameter in the added higher layer RRC signaling is on, which may be used to indicate that the DCI SRS request field is used to trigger aperiodic SRS resource set transmission or receive C L I measurement reference signals.
The method for specifying whether the DCI SRS request field is used for triggering the aperiodic SRS resource set to transmit or receive the C L I sounding reference signal can avoid confusion of the DCI SRS request field functions to a certain extent, i.e. can avoid that the DCI SRS request field simultaneously triggers different functions of the SRS resource set.
It should be noted that, in a possible implementation manner, if the DCI SRS request field further triggers other functions configured for the aperiodic SRS resource set, which are different from the function of cross link interference measurement, and the function of cross link interference measurement is executed in the same slot, the function corresponding to the aperiodic SRS resource set may be determined according to the function priority in order to prevent collision.
For example, if the priority of the cross link interference measurement function is lower than the priority of other simultaneously triggered functions, the function of cross link interference measurement of the SRS resource set, that is, the function of transceiving the reference signal by the SRS resource set C L I, may be dropped.
In addition, when there are at least two sets of aperiodic SRS resources used for transmitting or receiving a C L I sounding reference signal in the same slot, a guard interval (gp) of Y symbols is provided between two adjacent sets of aperiodic SRS resources, where Y is a positive integer not less than 1.
In gp, no signal can be transmitted, so that there is enough time for switching between uplink transmission and downlink reception, and it is ensured that data transceiving can be performed normally.
Based on the same inventive concept as the first embodiment, the following apparatuses are provided.
Example two
A second embodiment of the present invention provides a cross-link interference measurement reference signal configuration apparatus, which may be integrated in a base station, and a structure of the apparatus may be as shown in fig. 2, where the apparatus includes:
the configuration module 11 is configured to configure an aperiodic SRS resource set for a terminal or a terminal group when it is determined that the terminal or the terminal group needs to perform cross link interference measurement;
the sending module 12 is configured to send layer one signaling, where the layer one signaling is used to instruct the terminal or the terminal group to receive or send C L I sounding reference signals on the configured set of aperiodic SRS resources.
In a possible implementation manner, the configuring module 11 configures an aperiodic SRS resource set for a terminal or a terminal group, and may include:
the quantity of the aperiodic SRS resource sets configured for the terminal or the terminal group is consistent with that of the aperiodic SRS resource sets configured for the corresponding terminal or the terminal group by other base stations, and the time-frequency resource configuration and the time slot offset value of the aperiodic SRS resource sets with the same SRS resource set identification ID are consistent in one time slot.
In a possible implementation manner, the configuring module 11 configures an aperiodic SRS resource set for a terminal or a terminal group, and may further include: the functionality of the aperiodic SRS resource set is configured as cross-link interference measurements by higher layer radio resource control, RRC, signaling.
In a possible implementation manner, the layer one signaling includes a downlink control information SRS request field DCISRS request field, and the DCI SRS request field value is used to instruct the terminal or the terminal group to receive or transmit a C L I measurement reference signal on a configured aperiodic SRS resource set.
In accordance with an embodiment of the present invention, a method for transmitting and receiving sounding reference signals applied to a terminal is provided.
EXAMPLE III
A third embodiment of the present invention provides a method for receiving and transmitting a cross link interference measurement reference signal, where a flow of the steps of the method may be as shown in fig. 3, and the method includes:
step 201, receiving layer one signaling.
In this step, the terminal may receive layer one signaling.
Step 202, transmit-receive C L I measures the reference signal.
In this step, the terminal may receive or transmit a C L I sounding reference signal on a pre-configured set of aperiodic SRS resources according to the received layer one signaling.
It should be noted that the layer one signaling may include, but is not limited to, a DCI SRS request field, and may trigger the reception or transmission of the C L I sounding reference signal on a pre-configured set of aperiodic SRS resources according to the DCI SRS request field value.
Based on the same inventive concept as the third embodiment, the following apparatus is provided.
Example four

the receiving module 21 is configured to receive a layer one signaling;
the transceiver module 22 is configured to receive or transmit a C L I sounding reference signal on a pre-configured set of aperiodic SRS resources according to the layer one signaling.
In the following, the schemes provided in the first to fourth embodiments of the present invention are described by using a specific example, taking an example that a terminal or a terminal group is triggered to receive or transmit a C L I sounding reference signal on a configured aperiodic SRS resource set through a DCI SRS request field.
EXAMPLE five
Assume that three terminal groups (denoted by UE1, UE2, and UE3, respectively) belong to three different cells. Indicating information (SFI) of uplink and downlink transmission directions of subframes can be interacted among base stations of the three cells through an Xn interface, the frame structures of the three cells are all flexible frame structures through the SFI indication, at the moment, a terminal group of an interference source cell and a terminal group of an interfered cell cannot be distinguished, and at the moment, cross link interference measurement needs to be carried out on the three terminal groups respectively.
When determining that a terminal group needs to perform cross link interference measurement, a base station of each cell can configure an aperiodic SRS resource set for a service terminal group, assuming that three SRSresource sets containing a single-symbol SRS resource are configured, and time-frequency resource positions of the SRS resource sets corresponding to the same SRS resource set ID between each terminal group are configured consistently in one slot.
Fig. 5 is a schematic diagram of an aperiodic SRS resource set configured for each terminal group according to the fifth embodiment of the present invention, where SRS resource sets of each terminal are all configured in one slot for transmission, and a guard interval of one symbol is configured between all SRS resource sets for transmission and reception.
Assume for UE 1:
the aperiodicSRS-ResourceTrigger status values corresponding to SRS resource set ID1 and SRS resource set ID2 for transmitting C L I measurement reference signals are set to 1, and the aperiodicSRS-ResourceTrigger status value corresponding to SRSresource set ID3 for receiving C L I measurement reference signals is set to 2 for UE1, the corresponding DCI SRS request field values may be, but are not limited to being, set to 01 and 10, respectively.
Then, the DCI SRS request field value of 01 triggers the aperiodic SRS resource set ID1 and SRS resource set ID2 to transmit the C L I sounding reference signal, and the DCI SRS request field value of 10 triggers the aperiodic SRS resource set ID3 to receive the C L I sounding reference signal.
Assume for UE 2:
the aperiodicSRS-ResourceTrigger status values corresponding to SRS resource set ID1 and SRS resource set ID3 for transmitting C L I measurement reference signals are set to 2, and the aperiodicSRS-ResourceTrigger status value corresponding to SRSresource set ID2 for receiving C L I measurement reference signals is set to 3 for UE2, the corresponding DCI SRS request field values may be, but are not limited to being, set to 10 and 11, respectively.
Then, the DCI SRS request field value of 10 triggers the aperiodic SRS resource set ID1 and SRS resource set ID3 to transmit the C L I sounding reference signal, and the DCI SRS request field value of 11 triggers the aperiodic SRS resource set ID2 to receive the C L I sounding reference signal.
Assume for UE 3:
the aperiodicSRS-ResourceTrigger status values corresponding to SRS resource set ID2 and SRS resource set ID3 for transmitting C L I measurement reference signals are set to 3, and the aperiodicSRS-ResourceTrigger status value corresponding to SRSresource set ID1 for receiving C L I measurement reference signals is set to 1 for UE3, the corresponding DCI SRS request field values may be, but are not limited to being, set to 11 and 01, respectively.
Then, the DCI SRS request field value of 11 triggers aperiodic SRS resource set ID2 and SRS resource set ID3 to transmit C L I sounding reference signal, and the DCI SRS request field value of 01 triggers aperiodic SRS resource set ID1 to receive C L I sounding reference signal.
