For convenience of understanding, some contents related to the embodiments of the present application are described below:

1. NR redesigns Downlink (DL) PRS based on NR system.

1. PRS support transmissions in the Frequency Range (FR) 1 max 100M and FR2 max 400M. The NR PRS Bandwidth configuration is independent of a Bandwidth Part (BWP) configuration, and supports the UE to measure the PRS with a Measurement Gap (Measurement Gap) when the PRS Bandwidth is larger than the BWP Bandwidth.

2. The PRS supports beamforming, and introduces the concept of PRS resource (resource). The PRS resource Identification (ID) may correspond to 1 beam of 1 TRP. The 1 or more PRS resources may form a 1 PRS resource set (resource set), or 1 or more PRS resources may be contained in the 1 PRS resource set. One TRP may contain 1 or more PRS resources. Meanwhile, in order to increase audibility of the UE, PRS beam scanning and PRS beam repetition are supported. In addition, PRS reference neighbor cells RS are supported as spatial Quasi co-location (QCL) reference signals.

3. PRS support a staggered pattern (pattern) and support flexible pattern configurations. The comb (comb) structure of PRS resource can support {2,4,6,12}; the number of symbols (symbols) can support at least {2,4,6,12}. The combination of the number of symbols and comb size (size) supported at present is as follows:

	2symbols	4symbols	6symbols	12symbols
					Comb-2	{0,1}	{0,1,0,1}	{0,1,0,1,0,1}	{0,1,0,1,0,1,0,1,0,1,0,1}
Comb-4	NA	{0,2,1,3}	NA	{0,2,1,3,0,2,1,3,0,2,1,3}}

Comb-12	NA	NA	NA	{0,6,3,9,1,7,4,10,2,8,5,11}

2. repeat (repetition) on DL PRS.

2 new parameters were introduced: a DL PRS resource repetition factor (DL-PRS-ResourceRepetitionisFactor) and: DL PRS resource time interval (DL-PRS-ResourceTimeGap).

Wherein, the DL-PRS-resource repetition factor is used to control the number of times that the DL PRS resource is repeated, and the number of times may be 1,2, 4,6, 8, 16 and 32. The resource IDs of the repeated DL PRS resources are the same.

'DL-PRS-ResourceTimeGap' denotes the interval between 2 repeated DL PRS resources, and may take values of 1,2, 4,6, 8, 16, and 32, in slots (slots). This parameter is only provided to the UE if 'DL-PRS-resource repetition factor' is configured and takes a value greater than 1.

The time span of 1 PRS resource set containing repeated DL PRS resources should not exceed the periodicity of the DL PRS.

3. DL PRS muting (muting), otherwise known as DL PRS suppression.

In order to reduce interference in the cell, a mechanism of PRS muting is introduced. When the PRS frequency domain locations of 2 cells are the same, the serving base station may configure the PRS of one of the neighboring cells to mute (i.e., not send any PRS signal) within a certain period of time, so that the UE may be guaranteed to accurately receive the PRS signal of another cell without being interfered by inter-cells.

NR redefines the configuration of the muting, specifically:

the PRS muting can be configured at 'DL PRS resource set' level, can be represented by bitmap, and supports the following options (Option):

option1: every 1 bit in the bitmap (bitmap) corresponds to whether 1 or more consecutive periods of DL PRS resource set are muted. The 1 st bit may represent whether 1 or more cycles beginning at the DL PRS resource set are muted, the 2 nd bit represents whether 1 or more cycles subsequent to the DL PRS resource set are muted, and so on. When this bit is set to 0, the ue can consider all DL PRS resources muted during this time.

Wherein the continuous cycle length is indicated by the high-level parameter 'DL-PRS-MutingBitRepetitionfactor'.

Option2: the length of bitmap is equal to 'DL-PRS-ResourceRepetitionFactor'. A bit (bit) in the Bitmap represents whether a resource in the plurality of repeated DL PRS resources is failed or not.

4. Regarding TRP.

Transmission Point (TP): a cell, a portion of a cell, or a set of geographically co-located transmit antennas (e.g., an antenna array with one or more antenna elements) of a DL-PRS-only TP. The transmission points may include base station (ng-eNB or gNB) antennas, remote radio heads, remote antennas of base stations, DL-PRS TP only antennas, and so on. A cell may include one or more transmission points. For a homogeneous deployment, each transmission point may correspond to a cell.

Reception Point (RP): a cell, a portion of a cell, or a geographically collocated set of receive antennas (e.g., an antenna array) for the RP of the UL-SRS only. The reception point may include a base station (ng-eNB or gNB) antenna, a remote radio head, a remote antenna of a base station, an antenna of an uplink sounding reference signal (UL-SRS) RP only, and the like. A cell may include one or more reception points. For a homogeneous deployment, each reception point may correspond to a cell.

TP of PRS only: a TP transmits PRS signals only for PRS-based TBS positioning and is not associated with a cell.

Transmission Reception Point (TRP): a set of geographically co-located antennas (e.g., antenna arrays) supporting TP and/or RP functionality.

5. On demand (PRS).

Generally, PRS transmission is transmitted in a broadcast manner, PRS configuration is relatively fixed, and flexible modification of PRS configuration is not supported, which may cause some waste of resources. For example, a serving base station configures 128 TRPs with a large transmission bandwidth in a certain area, and in this area, only a part of UEs have a high positioning accuracy requirement, or only a part of UEs have a positioning requirement, so that the PRS covering a large bandwidth in the whole area for the part of UEs is not worth. For another example, in order to reduce overhead, PRSs with smaller bandwidth are configured in a certain area, and some UEs have stronger positioning accuracy, delay requirements, or power consumption requirements, and the existing protocol cannot support flexible configuration of PRSs meeting the requirements of the UEs.

The PRS configuration is flexibly increased or decreased specially for the positioning requirement of a certain UE or certain UEs. For example, the network starts to deploy PRS with smaller bandwidth, and for a UE with higher positioning accuracy requirement, the UE is configured with special PRS with larger bandwidth through signaling. For this reason, whether to introduce the on demand PRS is discussed.

If the On demand PRS is introduced, the interference problem encountered after the On demand PRS is configured is as follows: as shown in fig. 2, for example, in an area 201 (which may also be referred to as an on demand positioning area), based on an original PRS configuration, a PRS configuration is added (for example, a bandwidth is added, a PRS center frequency point is unchanged, and a bandwidth is changed from 20MHz to 100 MHz), so that the PRS configuration is changed to an on demand PRS configuration. Then the TRP transmits PRS in a bandwidth of 100MHz in this region. While outside this area (e.g., area 202), the PRS transmitted by the TRP is still transmitted at 20MHz according to the configuration of the conventional PRS due to the absence of on demand positioning.

The resources of the TRP at the edge of this area will cause some interference to terminal 2 of area 202 due to the configuration change (increasing the bandwidth to 100M). Since the TRP of the region 202 still transmits PRS according to 20M bandwidth, the terminal 2 still receives PRS according to 20M bandwidth, and PRS of 100M bandwidth at the edge of the region 201 may interfere with other signal transmissions (such as data transmissions) outside 20M bandwidth of the terminal 2. Therefore, the interference coordination processing method is provided.

The interference coordination processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The interference coordination processing method provided by the embodiment of the application comprises the following steps: the terminal receives first indication information, wherein the first indication information is used for indicating that the downlink reference signals transmitted by the M transmission receiving points TRP are interference resources, the first indication information carries first downlink reference signal configuration information of the M transmission receiving points TRP, and M is a positive integer. Wherein, the downlink reference signal includes: PRS, CSI-RS, or SSB. In the following, PRS is taken as an example, and CSI-RS or SSB can be implemented in a similar way.

Optionally, if the reference signal includes an SSB, the configuration of the SSB under a certain TRP includes at least one of: the physical cell identity PCI of the cell where the SSB is located, the SSB absolute frequency point position, the SSB half frame indication, the SSB period, the SSB subcarrier spacing, the SSB listening time window (SMTC), the SSB position in the SSB Burst (SSB-positioninglnburst, which is a bitmap for indicating whether a certain SSB in the SSB Burst is transmitted, 0 for no transmission, 1 for transmission), the SSB transmission power, the SFN offset of the SSB (SFN-SSBoffset with values {0,1,2, 8230, 15 }), the SSB index, the timing information of the TRP, etc. Then the interference suppression on PRS in the interference coordination processing method in the solution of the present application is also applicable to SSB.

Optionally, if the downlink reference signal includes a CSI-RS, the configuration of the CSI-RS under a certain TRP at least includes one of the following: the CSI-RS index, the PCI of a cell where the CSI-RS is located, a position of a CSI-RS reference point pointA, a position of a CSI-RS starting PRB, the number of CSI-RS bandwidth RBs, a CSI-RS subcarrier interval, a CSI-RS period, a CSI-RS mapping pattern, CSI-RS sending power, timing information of TRP and the like. Then, the interference suppression on PRS in the interference coordination processing method in the solution of the present application is also applicable to CSI-RS.

Wherein, the timing information of the TRP may be: the slot 0 of SFN0 of TRP sending PRS is offset from the slot 0 of SFN0 of UE serving cell, or the slot 0 of SFN0 of cell where TRP is located is offset from the slot 0 of SFN0 of UE serving cell.

Referring to fig. 3, fig. 3 is a flowchart of an interference coordination processing method according to an embodiment of the present application, and as shown in fig. 3, the method includes the following steps:

step 301, a terminal receives first indication information, where the first indication information is used to indicate positioning reference signals PRS transmitted by M transmission receiving points TRP as interference resources, the first indication information carries first PRS configuration information of the M TRPs, and M is a positive integer.

In this embodiment of the application, the M TRPs may be understood as TRPs in a certain positioning area, for example, the positioning area may be an On demand positioning area P, a positioning reference signal in the On demand positioning area may be an On demand PRS, and at this time, the first PRS configuration information may be understood as On demand PRS configuration information. The terminal may be understood as a terminal located at an outer edge of the positioning area, that is, the terminal is located outside the positioning area, and a distance from the edge of the positioning area is less than a preset value.

It should be understood that the above-mentioned M TRPs may be understood as TRPs adjacent to the terminal. Namely, TRP configuration information adjacent to the terminal is sent to the terminal through the first indication information. The TRP adjacent to the terminal may be understood as a TRP less than a preset value from the terminal. The preset value can be set according to actual needs, and is not further limited herein.

Optionally, in an embodiment, an indication identifier may be carried in the first indication information, and the PRS indicating the M TRP transmissions is displayed as an interference resource through the indication identifier. In another embodiment, the PRS of the M transmission receiver points TRP transmission can also be indicated as interference resources implicitly directly through the first PRS configuration information of the M TRPs. That is, the terminal may determine whether PRSs transmitted by M TRPs in the currently received first indication information are interference resources based on the first PRS configuration information.

After the terminal receives the first indication information, the terminal may perform interference coordination calculation according to the first indication information instead of performing positioning measurement, so that it is not necessary to report a positioning measurement result to the positioning server. For example, after the terminal receives the instruction, the terminal determines, according to the instruction, that the On demand positioning measurement is not performed.

It should be understood that the first indication information may be transmitted by the serving base station, or may be transmitted by the location server. When the first indication information is transmitted by the serving base station, the serving base station may first receive the first indication information transmitted by the location server and then forward the first indication information to the terminal. The first indication information sent by the location server to the serving base station and the first indication information sent by the serving base station to the terminal may be the same, or some parameters may be adjusted therein, which is not further limited herein.

Optionally, the signaling between the location server and the UE includes, but is not limited to, one of:

LTE Positioning Protocol (LPP), NR Positioning Protocol (NRPP), a combination of NRPPa and the first signaling, and a combination of LPPa and the first signaling.

The serving base station may transmit the first indication information to the terminal through the first signaling.

Optionally, the signaling between the serving base station and the terminal includes, but is not limited to, one of: radio Resource Control (RRC), medium Access Control Element (MAC CE), downlink Control Information (DCI), message (Msg) 1, msg3, and broadcast signaling and Paging (Paging).

Optionally, the communication signaling between the location server and the serving base station includes, but is not limited to, one of the following:

In an embodiment, the location server may indicate, through LPPa, a neighboring TRP or a neighboring TRP-associated gNB, and the neighboring TRP or the neighboring TRP-associated gNB sends, through an Xn interface, a PRS configuration of the neighboring TRP to the gNB.

In another embodiment, the location server may send, through the core network interface, the PRS configuration of the neighboring TRP to the serving gNB or the location server where the UE is located, and then send the PRS configuration to the serving gNB through LPPa signaling.

Optionally, in an embodiment, the first PRS configuration information satisfies any one of:

the first PRS configuration information is target PRS configuration information increased relative to second PRS configuration information;

the first PRS configuration information is PRS configuration information obtained by adding the target PRS configuration information to second PRS configuration information;

wherein the second PRS configuration information configures PRS configuration information for positioning measurement for the terminal.

In an embodiment, if the terminal does not currently have any PRS configuration information, the second PRS configuration information is an empty set, and it may be understood that the terminal does not have PRS configuration information of M transmission reception points TRP, any PRS configuration of the M transmission reception points TRP is increased configuration information, and the first PRS configuration information may be all PRS configuration information of the M transmission reception points TRP.

In another embodiment, the current PRS configuration information of the terminal includes PRS configuration information of some of the M transmitted reception points TRP, and in this case, the first PRS configuration information may be all of the M TRPs or PRS configuration information that is increased relative to the second PRS configuration information. For example, the second PRS configuration information of the existing configuration of the terminal is: a PRS resource bandwidth of M TRPs is a 20M configuration, and the indicated first PRS configuration information is a 100M increased or increased configuration for the PRS resource bandwidth. Or, the second PRS configuration information of the existing configuration of the terminal is: a certain resource period adjacent to the TRP is a configuration of 160ms, and the indicated first PRS configuration information is a configuration in which the PRS resource period is changed to be increased after 80ms or increased.

Optionally, in an embodiment, the first PRS configuration information includes: configuration of at least 1 PRS resource under a first TRP, wherein the first TRP is any one TRP of the M TRPs.

It should be understood that the first PRS configuration information includes PRS configuration information corresponding to each TRP, where some or all of the PRS configuration information corresponding to each TRP may be the same, or all of the PRS configuration information corresponding to each TRP may be different, which is not further limited herein.

In this embodiment, the first PRS configuration information may be a configuration of a certain PRS resource, a configuration of multiple PRS resources, or a configuration of all PRS resources in a certain PRS resource set or all PRS resources under the first TRP. That is, the first PRS configuration information includes any one of:
