Detailed Description

For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Fig. 1 is a schematic diagram of SRS positioning resource coordination between gnbs.

The method for configuring the positioning pilot frequency to mute is used for positioning the SRS resource set, is used for reducing uplink SRS transmission interference between positioning base stations, and indicates the muting method 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 offset range 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 a maximum of 16 SRS resources in each SRS resource set, and the maximum number of supported positioning SRS resource sets is UE capability, with a maximum of 16 resource sets being configurable per BWP.

The present application implements uplink muting between SRS positioning transmissions, that is, when a terminal device (UE) transmits SRS positioning information on a specific resource, a neighboring cell should reserve the resource, coordination between gnbs is required or LMF is enabled to coordinate the resource muting, and it is required to indicate to a terminal how to implement the SRS muting, so that the terminal served by each gNB (for example, gnbs 1 to 3 in fig. 1) knows the resource that can transmit the SRS.

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

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

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

Specifically, the configuration information comprises 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 silent resources in the Sounding Reference Signal (SRS) resource set.

The method adopts a bitmap (bitmap) mode to indicate a silent mode of SRS positioning transmission. Preferably, the configuration information indicates the SRS resource set in a bitmap manner, and a plurality of bitmaps may be used to periodically indicate the SRS resource set for transmitting the uplink positioning pilot, 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, in a first manner, as an optional embodiment of the method of the present application, all bits in at least one bitmap are indicated by first indication information, and correspond to transmission moments of 12 consecutive symbols in the SRS resource set; or, all bits in at least one bitmap are indicated by the second indication information, corresponding to silence moments of 12 consecutive symbols in the SRS resource set.

Preferably, at least one bit of one or a plurality of consecutive bits indicated by the first indication information contains the first indication information; at least one bit of one or a plurality of consecutive bits indicated by the second indication information contains the second indication information. For example, "0" in the bitmap represents not transmitting SRS, and "1" represents transmitting SRS.

Step 101B, in a second manner, as another optional 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 of a transmission time in one SRS resource set; and/or at least one bitmap comprises at least one second bit set, wherein the second bit set comprises at least one bit indicated by second indication information, and each bit corresponds to 1,2, 3, 4 or 6 continuous symbols of silence time in one SRS resource set.

Step 101C, configuring the first mode and the second mode simultaneously. Indicating the SRS resource set in a mode that the first bitmap and the second bitmap are overlapped;

when the nth bit (n=1-12) in the first bitmap and the second bitmap are indicated by the first indication information, 1,2, 3, 4 or 6 continuous symbols in the SRS resource set corresponding to the nth bit are used for transmitting time;

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

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

For example, terminal devices covered by the gnbs 1 to 3 respectively transmit SRS in the order indicated by the configuration information, and when the terminal device covered by the gNB1 transmits uplink positioning pilot according to the SRS resource set indicated by the configuration information, the terminal devices covered by the gnbs 2 to 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 transmission time of 1,2, 3, 4 or 6 continuous 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 the silence time of 1,2, 3, 4 or 6 continuous symbols in one SRS set respectively.

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

Fig. 3 is a schematic diagram of a bitmap indicated in the first manner.

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

Fig. 4 is a schematic diagram of a bitmap indicated in the second mode, where the number of SRS symbols is 1.

The second way is that each bit in the bitmap corresponds to a symbol of each sending moment configured in the SRS resource set, and the 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 each second bit set only comprises 1 bit. That is, when 12 bits in the bitmap are indicated with the first indication information or the second indication information, respectively, wherein the bit indicated with the first indication information is, for example, "1", 1 symbol in the corresponding SRS resource set is used for transmitting the pilot signal; wherein the bits indicated by the second indication information are, for example, "0", and muting is implemented at the moment when 1 symbol in the corresponding SRS resource set is located.

Fig. 5 is a schematic diagram of a bitmap indicated in the second mode, where the number of SRS symbols is 2.

In the second way, 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 each second bit set contains 2 bits. That is, when 12 bits in the bitmap are indicated with the first indication information or the second indication information, respectively, 2 bits indicated with each first indication information, and consecutive 2 symbols in the corresponding SRS resource set are used for transmitting the pilot signal; wherein muting is implemented at a time point where 2 symbols in the corresponding SRS resource set are located by 2 bits indicated by the second indication information. 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 schematic diagram of a bitmap indicated in the second mode, where 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 each second bit set contains 4 bits. That is, when 12 bits in the bitmap are indicated with the first indication information or the second indication information, respectively, 4 bits indicated with each first indication information, and consecutive 4 symbols in the corresponding SRS resource set are used for transmitting the pilot signal; wherein the muting is implemented at the moment of 4 symbols in the corresponding SRS resource set, with 4 bits indicated by the second indication information. At least one predetermined bit of the 4 bits of the first bit set is used as the first indication information "1", or at least one predetermined bit of the 4 bits of the second bit set is used as the second indication information "0".

Fig. 7 is a schematic diagram of a bitmap with both first and second mode indications configured.

The high layer configures the first mode and the second mode simultaneously, and the bitmaps of the first mode and the bitmaps of the second mode apply logical AND modes to obtain final bitmaps.

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

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