The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

The scheme of the application configures a positioning pilot frequency silencing mode for positioning an SRS resource set, reduces uplink SRS transmission interference between positioning base stations, and indicates the silencing mode of SRS positioning transmission in a bitmap mode.

The number of consecutive OFDM symbols of the positioning SRS resource is configurable, the set of configuration values may be {1, 2, 4, 8, 12}, the SRS resource time domain starting position may be any position in the slot, that is, the range of the offset is {0,1, …,13}, and the period and slot configuration of the SRS of the positioning pilot are consistent with the downlink PRS. There are 16 SRS resources in each SRS resource set at most, the maximum number of SRS resource sets supporting positioning is UE capability, and each BWP has 16 resource sets configurable at most.

The method and the device realize uplink muting between SRS positioning transmissions, that is, when a terminal device (UE) transmits SRS positioning information on a specific resource, an adjacent cell should reserve the resource, require coordination between gNBs or enable an LMF to coordinate resource muting, and indicate how to implement SRS muting to a terminal, so that terminals served by each gNB (e.g., gNB 1-3 in FIG. 1) know the resource capable of transmitting SRS.

Fig. 2 is a flowchart of an embodiment of the method of the present application.

The application provides an uplink positioning pilot frequency indication method, which is used for positioning an SRS resource set by configuring a positioning pilot frequency silencing mode and reducing uplink SRS sending interference between positioning base stations. Comprises the following steps:

step 101, the configuration information is used to indicate the transmission time and the silence time in the SRS resource set.

Specifically, the configuration information includes first indication information and/or second indication information; the first indication information is used for indicating resources used for sending positioning pilot frequency in a Sounding Reference Signal (SRS) resource set; the second indication information is used for indicating the muted resources in the Sounding Reference Signal (SRS) resource set.

The method and the device adopt a bitmap mode to indicate a silent mode for SRS positioning transmission. Preferably, the configuration information indicates the SRS resource set in a bitmap manner, and may periodically indicate the SRS resource set for transmitting the uplink positioning pilot in a plurality of bitmaps, where each bitmap includes 12 bits. And indicating bits in the bitmap by using the first indication information and/or the second indication information, wherein each bit corresponds to 1, 2, 3, 4 or 6 continuous symbols in the SRS resource set.

Step 101A, a first mode, as an alternative embodiment of the method of the present application, where all bits in at least one bitmap are indicated by first indication information, and correspond to transmission time of 12 consecutive symbols in the SRS resource set; or all bits in at least one bitmap are indicated by second indication information, and correspond to the silent time of 12 continuous symbols in the SRS resource set.

Preferably, in one or a plurality of consecutive bits indicated by the first indication information, at least one bit contains the first indication information; at least one bit of one or a plurality of continuous bits indicated by the second indication information contains the second indication information. For example, "0" in the bitmap represents no SRS transmission, and "1" represents SRS transmission.

Step 101B, a second mode, as another alternative embodiment of the method of the present application, at least one bitmap includes at least one first bit set, where the first bit set includes at least one bit indicated by first indication information, and each bit corresponds to a symbol at a transmission time in one SRS resource set, respectively; and/or at least one bitmap includes at least one second bit set, where the second bit set includes at least one bit indicated by second indication information, and each bit corresponds to 1, 2, 3, 4, or 6 consecutive symbols of a silence time in one SRS resource set, respectively.

And 101C, configuring the first mode and the second mode simultaneously. Indicating the SRS resource set by overlapping the first bitmap and the second bitmap;

when both of the N (N ═ 1-12) bits in the first bitmap and the second bitmap are indicated by first indication information, 1, 2, 3, 4, or 6 consecutive symbols in the SRS resource set corresponding to the N bit are used for a transmission time;

and when at least one of the M (M ═ 1-12) bits in the first bitmap and the second bitmap is indicated by second indication information, 1, 2, 3, 4 or 6 continuous symbols in the SRS resource set corresponding to the M bit are at silent time.

And 102, transmitting the uplink positioning pilot frequency according to the SRS resource positioned by the configuration information.

For example, terminal devices covered by the gNB 1-3 respectively transmit SRS according to the sequence indicated by the configuration information, and when the terminal device covered by the gNB1 transmits the uplink positioning pilot according to the SRS resource set indicated by the configuration information, the terminal devices covered by the gNB 2-3 implement muting according to the same SRS resource set indicated by the configuration information.

For example, the first bit set includes 1, 2, 3, 4, or 6 bits, and each first bit set corresponds to a transmission time of 1, 2, 3, 4, or 6 consecutive symbols in one SRS set; and/or the second bit sets comprise 1, 2, 3, 4 or 6 bits, and each second bit set corresponds to a silent moment of 1, 2, 3, 4 or 6 consecutive symbols in one SRS set respectively.

For another example, when the number of symbols in the SRS resource set is 1, the size of the bitmap is 12, that is, 1 bitmap may be used to indicate 12 SRS resource sets, and each SRS resource set transmits an uplink positioning pilot with 1 symbol; when the symbol of the SRS resource set is 2, the bitmap size is 6, that is, 1 bitmap may be used to indicate 6 SRS resource sets, and each SRS resource set transmits the uplink positioning pilot with 2 consecutive symbols. When the symbol of the SRS resource set is 4, the bitmap size is 3, that is, 1 bitmap may be used to indicate 3 SRS resource sets, and each SRS resource set transmits the uplink positioning pilot with 4 consecutive symbols. When the symbol of the SRS resource set is 6, the size of the bitmap is 2, that is, 1 bitmap may be used to indicate 2 SRS resource sets, and each SRS resource set transmits the uplink positioning pilot with consecutive 6 symbols.

Fig. 3 is a bitmap diagram indicating the first mode.

The first mode is that bits in the bitmap correspond to continuous transmission time configured in the SRS resource set, and a higher-layer configuration terminal adopts the first mode. When the bitmap is used periodically to indicate the corresponding SRS resource sets, each bitmap includes 12 bits, respectively corresponding to 1 symbol of the SRS resource set. When 12 bits in one bitmap are all indicated by the first indication information, at least one bit contains the first indication information, for example, 1, which indicates that symbols of 12 consecutive time instants in the SRS resource set corresponding to the bitmap are used for transmitting the pilot signal. When 12 bits in one bitmap are all indicated by the second indication information, at least one of the bits contains the second indication information, for example, 0, which indicates that the symbols of 12 consecutive time instants in the SRS resource set corresponding to the bitmap are all muted.

Fig. 4 is a bitmap diagram indicated by the second method, and the number of SRS symbols is 1.

The second way is that each bit in the bitmap corresponds to a symbol of each transmission time configured in the SRS resource set, and a higher-layer configuration terminal adopts the bitmap. When the number of symbols of the SRS resource set is 1, the bitmap size value is 12. The sum of the first bit set and the second bit set in each bitmap is 12, and each first bit set or second bit set only contains 1 bit. That is, when 12 bits in the bitmap are respectively indicated by the first indication information or the second indication information, where the bit indicated by the first indication information is, for example, "1", 1 symbol in the corresponding SRS resource set is used for transmitting the pilot signal; wherein a bit indicated by the second indication information is, for example, "0", and a time at which 1 symbol in the corresponding SRS resource set is located is muted.

Fig. 5 is a bitmap diagram indicated by the second method, and the number of SRS symbols is 2.

In the second scheme, when the number of symbols of the SRS resource set is 2, the bitmap size value is 6. The sum of the first bit set and the second bit set in each bitmap is 6, and each first bit set or second bit set comprises 2 bits. That is, when 12 bits in the bitmap are respectively indicated by the first indication information or the second indication information, wherein 2 bits indicated by each first indication information are used for transmitting the pilot signal, consecutive 2 symbols in the corresponding SRS resource set; wherein, the 2 bits indicated by the second indication information are used for implementing the muting at the time of the 2 symbols in the corresponding SRS resource set. At least one predetermined bit in the first bit set is a first indication information "1", or at least one predetermined bit in the second bit set is a second indication information "0".

Fig. 6 is a bitmap diagram indicating the second mode, and the number of SRS symbols is 4.

When the number of symbols of the SRS resource set is 4, the bitmap size value is 3. The sum of the first bit set and the second bit set in each bitmap is 3, and each first bit set or second bit set comprises 4 bits. That is, when 12 bits in the bitmap are respectively indicated by the first indication information or the second indication information, wherein 4 bits indicated by each first indication information are used for transmitting the pilot signal in the corresponding SRS resource set, which are consecutive 4 symbols; wherein, the 4 bits indicated by the second indication information are used for implementing the muting at the time of 4 symbols in the corresponding SRS resource set. At least one predetermined bit of the 4 bits of the first bit set is used as first indication information "1", or at least one predetermined bit of the 4 bits of the second bit set is used as second indication information "0".

Fig. 7 is a schematic diagram of a bitmap indicating the simultaneous configuration of the first mode and the second mode.

And the high layer simultaneously configures a first mode and a second mode, and the bitmap of the first mode and the bitmap of the second mode apply a logical AND mode to obtain a final bitmap.

For example, when all bits of the first bitmap are indicated by the first indication information, a part of bits of the second bitmap are the first bit set, and the other part of bits of the second bitmap is the second bit set, the final bitmap is indicated in the manner of the second bitmap; and when all bits of the first bitmap are indicated by the second indication information, one part of bits of the second bitmap are the first bit set, and the other part of bits of the second bitmap are the second bit set, indicating the final bitmap according to the mode of the first bitmap.

That is, the bits at the same positions in the first bitmap and the second bitmap are logically anded, and the generated bitmap is used to indicate the symbols in the SRS resource set for transmission or muting.
