Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a method, apparatus, communication device, and storage medium for updating SRS configuration information. Background Technology

[0002] In wireless communication technology, a positioning method has been introduced for terminals in the Radio Resource Control (RRC) inactive state and the RRC idle state. In one scenario embodiment, the Sounding Reference Signal (SRS) used for uplink positioning is configured on a per-cell basis. Therefore, when a terminal moves from one cell to another, it needs to reacquire the SRS configuration information. Thus, if the terminal moves frequently between different cells, it needs to frequently acquire the SRS configuration information, which leads to increased power consumption. Summary of the Invention

[0006] The SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information.

[0007] According to a second aspect of the present disclosure, a method for updating SRS configuration information is provided, wherein the method is performed by an access network device, and the method includes:

[0008] Send SRS configuration information to the terminal;

[0009] The SRS configuration information includes first configuration information and second configuration information; the first configuration information is used by the terminal to transmit SRS based on the first configuration information or based on updated first configuration information; the second configuration information is used by the terminal to transmit SRS in at least two cells based on the second configuration information. According to a third aspect of this disclosure, an SRS configuration information updating apparatus is provided, wherein the apparatus includes:

It is understood that the second configuration information applies to at least two cells, meaning the terminal transmits the SRS in at least two cells based on the same second configuration information.

[0058] In one embodiment, in response to the terminal moving from a first cell to a second cell, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. It is understood that the first configuration information may differ in different cells (e.g., the first cell and the second cell), therefore the terminal needs to update the first configuration information, i.e., the terminal transmits SRS in different cells based on different first configuration information.

[0059] In one embodiment, in response to a change in the measured value being greater than or equal to a first threshold, the first configuration information in the SRS configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. It is understood that movement of the terminal can cause changes in the measured value. The first configuration information can also differ at different locations within the same cell, therefore the terminal needs to update the first configuration information, i.e., the terminal transmits SRS at different locations within the same cell based on different first configuration information.

[0060] In one embodiment, the first threshold is determined based on third specified information sent by the network device; and / or, the first threshold is determined based on predetermined protocol information; the network device is an access network device or an LMF (Local Modem). It should be noted that the third specified information may be sent to the terminal before updating the first configuration information. When the network device is an LMF, the third specified information can be sent via Long Term Evolution (LPP) Positioning Protocol (LTP) messages. When the network device is an access network device, the third specified information can be sent via system information broadcast, Radio Resource Control (RRC) messages, or Medium Access Control (MAC) control elements (CEs).

For example, the measurement values ​​include at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR, without limitation. In one embodiment, the L3 measurement value can be the measurement result of Radio Resource Management (RRM). It should be noted that L1-RSRP is the RSRP measured at the L1 layer, and the others are similar.

[0063] In one embodiment, in response to a change in the measured value being greater than or equal to a first threshold, the first configuration information in the SRS configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. The measured value is a measurement value determined based on a reference signal, which is either a Synchronization Signal / PBCH Block (SSB) or a Channel State Information Reference Signal (CSI-RS). The CSI-RS may include a phase tracking reference signal and / or a tracking reference signal.

[0064] In one embodiment, in response to a change in the measured value being greater than or equal to a first threshold, the first configuration information in the SRS configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. The measured value is a measured value determined based on a reference signal, which is an SSB or CSI-RS; the reference signal is determined to be a pathloss reference signal, a reference signal indicated by Transmission Configuration Indication State (TCI state) information, and / or a reference signal indicated by spatial relation information. The CSI-RS may include a phase tracking reference signal and / or a tracking reference signal. The reference signal being determined as a pathloss reference signal, a reference signal indicated by TCI state information, and / or a reference signal indicated by spatial relation information may be determined by the terminal based on the first configuration information sent by the network device, or determined by the terminal when updating the first configuration information.

[0065] In one embodiment, in response to the terminal performing cell reselection, the first configuration information in the SRS configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information.

[0066] In one embodiment, the first configuration information in the SRS configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information; the first configuration information includes at least one of the following: uplink beam information; timing advance (TA) information; path loss reference signal information; and power control related parameter information.

[0067] Here, the power control related parameter information can be P0 and / or alpha.

[0068] It should be noted that uplink beam information can be referred to as spatial relation info, uplink transmission configuration indication (TCI) state, or spatial transmission filter.

[0069] In one embodiment, the first configuration information in the SRS configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information; the second configuration information includes at least one of the following: time-domain parameter information; frequency-domain parameter information; comb parameter information; and power control related parameter information.

[0070] In one embodiment, the time-domain parameter information indicates at least one of the following parameters: period, slot offset, start symbol position, number of symbols, and number of repetitions.

[0071] In one embodiment, the frequency domain parameter information indicates at least one of the following parameters: frequency domain position (freqDomainPosition), frequency domain shift (freqDomainShift), and frequency hopping (freqHopping).

[0072] In one embodiment, the comb parameter information indicates at least one of the following parameters: comb offset and cyclic shift.

[0073] In one embodiment, based on a first reference signal, the first configuration information in the probe reference signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information.

[0074] In one embodiment, the first reference signal is one of the following:

[0075] Synchronization Signal and Broadcast Channel Block (SSB);

[0076] Channel State Information Reference Signal (CSI-RS);

[0077] Phase tracking reference signal; and

[0078] Tracking reference signal.

[0079] In this embodiment of the disclosure, the measured value corresponding to the first reference signal is greater than the measured value corresponding to the second reference signal. Here, the reference signal may include a first reference signal and a second reference signal, and the second reference signal may be a reference signal other than the first reference signal. The first reference signal and the second reference signal may be reference signals of the same type, for example, both being SSB.

[0080] For example, the measured value corresponding to the first reference signal is greater than that of any other reference signal in the reference signals excluding the first reference signal. For instance, the reference signals include a first SSB and a second SSB, where the first reference signal is the first SSB and the second reference signal is the second SSB. Here, the measured value corresponding to the first SSB can be greater than the measured value corresponding to the second SSB. Of course, the reference signal is not limited to SSBs; it can also be other reference signals, such as CSI-RS, phase tracking reference signals, or tracking reference signals, etc., and is not limited here.

[0081] It should be noted that in this disclosure, the first reference signal is used as the first SSB to illustrate the example of updating the first configuration information in the SRS configuration information based on the first reference signal. However, the scenario applicable to the first SSB is also applicable to the Channel State Information Reference Signal (CSI-RS), the Phase Tracking Reference Signal, and the Tracking Reference Signal. That is, in this disclosure, the first SSB can be replaced by the Channel State Information Reference Signal (CSI-RS), the Phase Tracking Reference Signal, or the Tracking Reference Signal.

[0082] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information.

[0083] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information; the measurement value corresponding to the first SSB is greater than a second threshold; or, the measurement value corresponding to the first SSB is greater than the measurement value corresponding to the second SSB; wherein the measurement value includes at least one of the following: RSRP, RSRQ, and SINR. For example, the measurement value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0084] For example, the measurement value corresponding to the first SSB can be the largest measurement value among all the measurement values ​​corresponding to all SSBs, but is not limited to the largest measurement value.

[0085] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSB includes updating the uplink beam of the SRS to the beam corresponding to the first SSB. This can also be understood as updating the SRS to have a quasi-co location type D relationship with the first SSB.

[0086] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and a second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSB includes updating the SRS path loss reference signal to the first SSB.

[0087] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSB includes updating the SRS path loss reference signal to at least two of the first SSBs.

[0088] In one embodiment, the number of the first SSBs is at least two; the number of the first SSBs is determined based on first designated information or predetermined protocol information sent by the network device; wherein, the network device is an access network device or a Position Management Function (LMF). Based on the first SSBs, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein, the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSBs includes: updating the path loss reference signal of the SRS to the at least two first SSBs. When the network device is an LMF, the first designated information can be sent via Long Term Evolution Positioning Protocol (LPP) messages. When the network device is an access network device, the first designated information can be sent via System Information Broadcast, Radio Resource Control (RRC) messages, or Medium Access Control (MAC) control element (CE).

[0089] In one embodiment, the number of the first SSBs is at least two; the number of the first SSBs is determined based on first information or predetermined protocol information sent by the network device; wherein, the network device is an access network device or a Location Management Function (LMF). Based on the first SSBs, the first configuration information in the Sound Reference Signal (SRS) configuration information is updated; wherein, the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSBs includes: updating the path loss reference signal of the SRS to at least two of the first SSBs. Path loss is determined based on the average of the measurements corresponding to at least two of the first SSBs; wherein, the measurements include at least one of the following: RSRP, RSRQ, and SINR. For example, the measurements include at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0090] It should be noted that when there are multiple first SSBs, it is not necessary to determine the path loss reference signal (pathlossRS), because determining the path loss RS is actually to determine the corresponding measured value. Therefore, in this case, the path loss can be determined directly based on the average measured value of multiple SSBs. It should also be noted that multiple SSBs (e.g., multiple first SSBs) can refer to multiple SSBs where the measured value of each SSB is higher than a threshold, or multiple SSBs being the N SSBs with the strongest measurement quality (which can be beam-based measurements) among all SSBs (the first N SSBs arranged in descending order); wherein the measured value includes at least one of the following: RSRP, RSRQ, and SINR. For example, the measured value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0091] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSB includes: updating the TA configured in the first configuration information based on the measurement value corresponding to the first SSB and a mapping relationship; the mapping relationship is the relationship between the TA and the measurement value corresponding to the SSB, or the mapping relationship is the relationship between the TA adjustment value and the change value of the measurement value corresponding to the SSB; the measurement value includes at least one of the following: RSRP, RSRQ, and SINR. For example, the measurement value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0092] In one embodiment, based on a first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; wherein the SRS configuration information includes the first configuration information and second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSB includes: updating the TA configured in the first configuration information based on the measurement value corresponding to the first SSB and a mapping relationship; the mapping relationship is the relationship between the TA and the measurement value corresponding to the SSB, or the mapping relationship is the relationship between the TA adjustment value and the change value of the measurement value corresponding to the SSB; the measurement value includes at least one of the following: RSRP, RSRQ, and SINR. For example, the measurement value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0093] For example, if the measured value changes by X dB, then the TA changes by Y us. Thus, a mapping relationship between the measured value and the TA can be determined based on this change rule. After obtaining the current measured value, the TA corresponding to the measured value can be determined based on the measured value and the mapping relationship. It is understood that as the measured value increases, the TA decreases; as the measured value decreases, the TA increases.

[0094] In one embodiment, a mapping relationship is determined based on second specified information or predetermined protocol information sent by the network device; the mapping relationship is the relationship between the measurement values ​​corresponding to the TA and SSB, or the mapping relationship is the relationship between the TA adjustment value and the change value of the measurement value corresponding to the SSB; the measurement values ​​include at least one of the following: RSRP, RSRQ, and SINR; for example, the measurement values ​​include at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR. The network device is an access network device or an LMF. Based on the first SSB, the first configuration information in the Sounding Reference Signal (SRS) configuration information is updated; the SRS configuration information includes the first configuration information and the second configuration information; the terminal transmits SRS in at least two cells based on the second configuration information. Updating the first configuration information based on the first SSB includes: updating the TA configured in the first configuration information based on the measurement value corresponding to the first SSB and the mapping relationship. The number of the first SSB is at least two; the measurement value of the first SSB is determined based on the average of the measurement values ​​corresponding to the at least two first SSBs.

[0095] It should be noted that multiple SSBs (e.g., multiple first SSBs) can refer to multiple SSBs where the measurement value of each SSB is higher than a threshold, or multiple SSBs being the N SSBs with the strongest measurement quality (which can be beam-based measurements) among all SSBs (the first N SSBs arranged in descending order); wherein, the measurement value includes at least one of the following: RSRP, RSRQ, and SINR. When the network device is an LMF, the second designation information can be sent via Long Term Evolution Positioning Protocol (LPP) messages. When the network device is an access network device, the second designation information can be sent via System Information Broadcast, Radio Resource Control (RRC) messages, or Medium Access Control (MAC) Control Element (CE).

This can also be understood as updating the SRS to a quasi-colocation type D relationship with the first SSB.

[0178] In one embodiment, SRS configuration information is sent to a terminal; wherein the SRS configuration information includes first configuration information and second configuration information; the first configuration information is used by the terminal to transmit SRS based on the first configuration information or based on updated first configuration information; the second configuration information is used by the terminal to transmit SRS in at least two cells based on the second configuration information.

Exemplarily, the first SSB used by the terminal to update the first configuration information includes: the first SSB being used by the terminal to update the path loss reference signal in the first configuration information to the first SSB.

[0179] In one embodiment, SRS configuration information is sent to a terminal; wherein the SRS configuration information includes first configuration information and second configuration information; the first configuration information is used by the terminal to transmit SRS based on the first configuration information or based on updated first configuration information; the second configuration information is used by the terminal to transmit SRS in at least two cells based on the second configuration information. A first SSB is sent; wherein the first SSB is used by the terminal to update the first configuration information based on the first SSB. Exemplarily, the first SSB used by the terminal to update the first configuration information includes: the first SSB being used by the terminal to update the path loss reference signal in the first configuration information to at least two first SSBs. The at least two first SSBs are used by the terminal to determine path loss based on the average of the measurements corresponding to the at least two first SSBs.

[0180] In one embodiment, a first SSB is sent to the terminal; wherein the first SSB is used by the terminal to update the first configuration information based on the first SSB; the number of the first SSBs is at least two; the at least two first SSBs are used by the terminal to determine path loss based on the average of the measurements corresponding to the at least two first SSBs. SRS configuration information is sent to the terminal; wherein the SRS configuration information includes first configuration information and second configuration information; the first configuration information is used by the terminal to transmit SRS based on the first configuration information or based on the updated first configuration information; the second configuration information is used by the terminal to transmit SRS in at least two cells based on the second configuration information.

[0181] In one embodiment, a first indication information is sent to the terminal; wherein the first indication information is used to indicate the number of the first reference signals.

[0182] For example, when the network device is an LMF (Local Management Function), the first designation information can be sent via a Long Term Evolution Positioning Protocol (LPP) message. When the network device is an access network device, the first designation information can be sent via system information broadcast, Radio Resource Control (RRC) message, or Medium Access Control (MAC) control element (CE).

[0183] In one embodiment, a first SSB is sent to the terminal; wherein the first SSB is used by the terminal to update the first configuration information based on the first SSB; the number of the first SSBs is at least two; the at least two first SSBs are used by the terminal to determine path loss based on the average of the measurement values ​​corresponding to the at least two first SSBs; the measurement values ​​include at least one of the following: RSRP, RSRQ, and SINR. For example, the measurement values ​​include at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR. SRS configuration information is sent to the terminal; wherein the SRS configuration information includes first configuration information and second configuration information; the first configuration information is used by the terminal to transmit SRS based on the first configuration information or based on the updated first configuration information; the second configuration information is used by the terminal to transmit SRS in at least two cells based on the second configuration information.

[0184] It should be noted that when there are multiple first SSBs, it is not necessary to determine the path loss reference signal (pathlossRS), because determining the path loss RS is actually to determine the corresponding measured value. Therefore, in this case, the path loss can be determined directly based on the average measured value of multiple SSBs. It should also be noted that multiple SSBs (e.g., multiple first SSBs) can refer to multiple SSBs where the measured value of each SSB is higher than a threshold, or multiple SSBs being the N SSBs with the strongest measurement quality (which can be beam-based measurements) among all SSBs (the first N SSBs arranged in descending order); wherein the measured value includes at least one of the following: RSRP, RSRQ, and SINR. For example, the measured value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

A first SSB is sent; wherein the first SSB is used by the terminal to update the first configuration information based on the first SSB. Exemplarily, the first SSB being used by the terminal to update the first configuration information includes: the first SSB being used by the terminal to update the TA in the first configuration information based on the measurement value corresponding to the first SSB and a mapping relationship; wherein the mapping relationship is the relationship between the TA and the measurement value corresponding to the SSB, or the mapping relationship is the relationship between the TA adjustment value and the change value of the measurement value corresponding to the SSB; the measurement value includes at least one of the following: RSRP, RSRQ, and SINR. For example, the measurement value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0186] For example, if the measured value changes by X dB, then the TA changes by Y us. Thus, a mapping relationship between the measured value and the TA can be determined based on this change rule. After obtaining the current measured value, the TA corresponding to the measured value can be determined based on the measured value and the mapping relationship. It is understood that as the measured value increases, the TA decreases; as the measured value decreases, the TA increases.

[0187] In one embodiment, second specified information is sent to the terminal; wherein the second specified information is used to indicate the mapping relationship.

[0188] For example, when the network device is an LMF (Local Management Function), the second designation information can be sent via a Long Term Evolution Positioning Protocol (LPP) message. When the network device is an access network device, the second designation information can be sent via system information broadcast, Radio Resource Control (RRC) message, or Medium Access Control (MAC) control element (CE).

The measurement value includes at least one of the following: RSRP, RSRQ, and SINR; for example, the measurement value includes at least one of L1-RSRP, L1-RSRQ, L1-SINR, L3-RSRP, L3-RSRQ, and L3-SINR.

[0190] It should be noted that multiple SSBs (e.g., multiple first SSBs) can refer to multiple SSBs where the measurement value of each SSB is higher than the threshold, or multiple SSBs being the N SSBs with the strongest measurement quality (which can be beam-based measurements) among all SSBs (the first N SSBs arranged in descending order); wherein the measurement value includes at least one of the following: RSRP, RSRQ, and SINR.

[0216] Wherein, the network device is an access network device or a first network function; the first specified information is used to indicate the number of the first reference signals; the second specified information is used to indicate the relationship between the measurement values ​​corresponding to TA and SSB, or the mapping relationship is the relationship between the TA adjustment value and the change value of the measurement value corresponding to SSB; the third specified information indicates the first threshold and / or the second threshold.

[0229] Here, it could be that the access network device obtains the SRS configuration information based on the terminal's request.

[0230] Step 122: In response to moving from the first position to the second position, the terminal updates the first configuration information;

[0231] Here, it could be: in response to the satisfaction of a predetermined condition, determining that the terminal moves from the first position to the second position.

[0232] It is understood that the predetermined condition is a condition associated with the movement of the terminal, for example, the terminal moving from a first cell to a second cell.
