[0255] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several access devices 12.

[0256] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE).

Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0257] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0258] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0259] Access device 12 and UE 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0260] In some embodiments, the wireless communication system described above may further include core network equipment 13.

[0261] Several access network devices 12 are connected to core network devices 13. The core network device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the core network device can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS); or the core network device 13 can be a core network device in 5G, such as a Policy Control Function (PCF), a Session Management Function (SMF), an Access and Mobility Management Function (AMF), a Unified Data Management (UDM), or a User Plane Function (UPF). The implementation of the core network device 13 is not limited in this embodiment.

[0262] To better understand the technical solutions described in any embodiment of this disclosure, firstly, a partial explanation of UE positioning in related technologies will be provided:

[0263] In one embodiment, the Reference Signal (SRS) for uplink positioning is configured per cell. Therefore, when the UE moves from one cell to another, it needs to re-acquire the SRS configuration. However, this results in increased power consumption.

[0264] In one embodiment, the network device involved in this disclosure may also be a core network device, which may include a location management function or a network element. Optionally, the location management function or network element includes a location management function entity, and the location server may be implemented as any of the following: a location management function (LMF), an enhanced serving mobile location center (E-SMLC), a secure user plane location (SUPL), and a secure user plane location platform (SUPL LP).

[0265] This disclosure provides an information processing method executed by a UE, comprising: determining SRS-related configuration operations of the UE in at least two cells. The determination of SRS-related configuration operations of the UE in at least two cells includes, but is not limited to, at least one of the following: sending a request to a network device to request reconfiguration of SRS configuration in at least two cells; and determining, based on indication information, whether to deactivate or activate SRS transmission for the UE in at least two cells.

[0266] like Figure 2 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0267] Step S21: Determine the SRS-related configuration operations of the UE in at least two cells;

[0268] Specifically, determining the SRS-related configuration operations of the UE in at least two cells includes at least one of the following:

[0269] Send a request to the network device to request the reconfiguration of the SRS configuration in at least two cells;

[0270] Based on the instruction information, determine whether the UE is deactivated or activated for SRS transmission in at least two cells.

[0271] In one embodiment, the network equipment may include access network equipment and / or core network equipment. The access network equipment may be, but is not limited to, a base station. The core network equipment may be a logical node or function that can be flexibly deployed in the core network; for example, the core network equipment may be an LMF (Logical Function).

[0272] In one embodiment, LMF can be the location management function entity described in the above embodiments.

[0273] In one embodiment, the base station may be, but is not limited to, various types of base stations, such as, but not limited to, at least one of the following: 3G base station, 4G base station, 5G base station and other evolved base stations.

[0274] In one embodiment, the UE can be, but is not limited to, various mobile terminals or fixed terminals; for example, the UE can be, but is not limited to, a mobile phone, a computer, a server, a wearable device, an in-vehicle device, a game control platform, or a multimedia device.

[0275] In one embodiment, SRS-related configuration operations include, but are not limited to, at least one of the following: requesting SRS configuration, re-requesting SRS configuration, activating SRS transmission, and deactivating SRS transmission.

[0276] In one embodiment, at least two cells can be two or more cells. For example, SRS configuration of the UE in at least two cells means that the SRS configuration applies to the at least two cells in which the UE is located. For example, deactivating or activating SRS transmission in at least two cells means that the deactivation or activation of SRS transmission applies to the at least two cells in which the UE is located. For example, SRS configuration includes SRS resource configuration.

[0277] In one embodiment, the request is an SRS reconfiguration request.

[0278] In one embodiment, the request can be used to request SRS configuration in at least two cells.

[0279] In one embodiment, sending a request to the network device in step S21 includes sending a request to the base station.

[0280] In another embodiment, sending a request to the network device in step S21 includes sending a request to the LMF. In some embodiments of this disclosure, the interaction between the UE and the LMF (or core device) is implemented through a base station; exemplaryly, the UE sending a request to the LMF includes: the UE sending a request to the LMF through the base station. This UE sending a request to the LMF through the base station includes: the UE sending a request to the base station, and the base station forwarding the request to the LMF. Exemplarily, this forwarding can be transparent forwarding.

[0281] In one embodiment, the SRS configuration includes, but is not limited to, at least one of the following: time-domain resource information, frequency-domain resource information, comb parameters, SRS sequence ID, power-related parameters, number of ports, timing advance (TA) information, spatial relation information, and pathloss reference signal information.

[0282] In one embodiment, the time-domain resource information includes, but is not limited to, at least one of the following: period, time slot offset, starting symbol position, number of symbols, and number of retransmissions.

[0283] In one embodiment, the frequency domain resource information includes, but is not limited to, at least one of the following: frequency domain location, frequency domain offset, and frequency hopping.

[0284] In one embodiment, the comb parameter includes, but is not limited to, at least one of the following: comb offset and cyclic shift.

[0285] In one embodiment, the power-related parameters include, but are not limited to, at least one of the following: reference power (P0) and / or adjustment parameter (alpha).

[0286] The UE can be configured to perform SRS transmission in at least two cells.

[0287] In one embodiment, the indication information may be provided by the network device. For example, the UE receives the indication information sent by the network device and determines whether to deactivate or activate SRS transmission in at least two cells based on the indication information.

[0288] In one embodiment, the indication information is used to indicate whether to deactivate or activate SRS transmission. Exemplarily, the indication information can be one or more bits. If the indication information is a first value, such as "00", it indicates whether to deactivate SRS transmission; or if the indication information is a second value, such as "01", it indicates whether to activate SRS transmission. Thus, different values ​​of the indication information can be used to deactivate or activate SRS transmission.

[0289] In this embodiment of the disclosure, the UE can determine the SRS-related configuration operations of the UE in at least two cells. This determination includes: sending a request to the network device to request reconfiguration of the SRS configuration in at least two cells, and / or determining, based on indication information, whether to deactivate or activate SRS transmission in at least two cells. Thus, this embodiment of the disclosure provides SRS-related configuration for the UE in multiple cells. For example, it can realize the reconfiguration of the UE's SRS configuration in multiple cells, and / or the deactivation or activation of SRS transmission in multiple cells. This eliminates the need to configure the SRS-related settings for a single cell when the UE moves from one cell to another, thereby ensuring high-precision positioning while reducing power consumption.

[0290] In some embodiments, determining the SRS-related configuration operations of the UE in at least two cells in step S21 includes: determining the SRS-related configuration operations of the UE in at least two cells based on the UE moving out of the coverage area of ​​at least two cells.

[0291] This disclosure provides an information processing method executed by a UE, including: determining SRS-related configuration operations of the UE in at least two cells based on the UE moving out of the coverage area of ​​at least two cells.

[0292] In this way, it is possible to realize how to re-request SRS configuration and / or deactivate or activate SRS transmission when the UE moves out of at least two cells.

[0293] In some other embodiments, determining the SRS-related configuration operations of the UE in at least two cells in step S21 includes: determining the SRS-related configuration operations of the UE in at least two cells based on the range covered by the UE moving from one cell to another.

[0294] This disclosure provides an information processing method executed by a UE, including: determining SRS-related configuration operations of the UE in at least two cells based on the coverage area of ​​the UE moving from one cell to another.

[0295] In this way, SRS-related configurations for at least two cells can be implemented when a UE moves from one cell to another.

[0296] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0297] In one embodiment, the request also includes one of the following:

[0298] SRS transmission activation request, whereby the SRS transmission activation request is used to request the activation of SRS transmission;

[0299] SRS Transport Deactivation Request, which is used to request the deactivation of SRS transport.

[0300] For example, activating SRS transmission means starting SRS transmission. Deactivating SRS transmission means stopping SRS transmission.

[0301] Thus, this request can also be used to request the activation or deactivation of SRS transmissions.

[0302] In one embodiment, determining the SRS-related configuration operations of the UE in at least two cells in step S21 may include sending an SRS transmission activation request or an SRS transmission deactivation request to the network device. Thus, the UE can send an SRS transmission activation request or an SRS transmission deactivation request to the network device to request indication information for the deactivation or activation of SRS transmissions in at least two cells; this facilitates subsequent SRS transmission deactivation or activation operations.

[0303] Of course, in other embodiments, the SRS transmission activation request and / or SRS transmission deactivation request can be replaced by an indication information request. For example, the UE sends an indication information request to the network device, the indication information request being used to request indication information. Thus, the indication information can also be obtained after the UE actively requests it.

[0304] This disclosure provides an information processing method executed by a UE, comprising: receiving a response sent by a network device, the response including SRS configuration. In this way, the UE can obtain the SRS configuration of the UE in at least two cells, thereby facilitating SRS transmission of the UE in at least two cells.

[0305] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0306] In some embodiments, the network device is a base station; sending a request to the network device includes: sending a request to the base station based on a random access procedure.

[0307] like Figure 3 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0308] Step S31: Send a request to the base station based on the random access procedure.

[0309] In some embodiments of this disclosure, the request may be the same as the request described in the above embodiments. For example, the request may be an SRS reconfiguration request.

[0310] In one embodiment, the random access procedure includes either a four-step random access procedure or a two-step random access procedure.

[0311] In some embodiments, step S31 includes at least one of the following:

[0312] MSG1, based on a four-step random access procedure, sends a request to the base station.

[0313] MSG3, based on a four-step random access procedure, sends a request to the base station.

[0314] MSGA, based on a two-step random access procedure, sends a request to the base station.

[0315] like Figure 4 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0316] Step S41: Send a request to the base station based on MSG1 of the four-step random access procedure; and / or, send a request to the base station based on MSG3 of the four-step random access procedure; and / or, send a request to the base station based on MSGA of the two-step random access procedure.

[0317] In some embodiments of this disclosure, the request may be the same as the request described in the above embodiments. For example, the request may be an SRS reconfiguration request.

[0318] In some embodiments, step S41, based on the MSG1 of the four-step random access procedure, sends a request to the base station, including:

[0319] MSG1, based on the four-step random access procedure, sends a dedicated random access preamble to the base station, where the dedicated random access preamble is used to indicate the request.

[0320] like Figure 5 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0321] Step S51: Based on the four-step random access procedure MSG1, send a dedicated random access preamble to the base station, wherein the dedicated random access preamble is used to indicate the request.

[0322] For example, during the four-step random access process, the UE sends a dedicated random access preamble based on MSG1, where the dedicated random access preamble indicates a request. The dedicated random access preamble refers to a set of random access preambles determined based on base station indications or default rules. The transmission of this random access preamble is only used to indicate the request and is not used in the traditional random access process from idle or inactive state to connected state, nor for purposes such as beam failure recovery or link failure recovery.

[0323] Thus, in this embodiment of the disclosure, a request for SRS reconfiguration (i.e., an SRS reconfiguration request) can be sent by MSG1 through a dedicated random access preamble during the four-step random access process. Furthermore, since this request can be indicated by the dedicated random access preamble sent in MSG1, no additional signaling transmission is required, thereby reducing signaling overhead.

[0324] In some embodiments, based on the four-step random access procedure MSG1, a dedicated random access preamble is sent to the base station, including:

[0325] In the four-step random access process, a dedicated random access preamble is sent to the base station based on dedicated random access time-frequency domain resources. These dedicated random access time-frequency domain resources include time-frequency domain resources specifically used to indicate the request. These resources include at least one of dedicated random access time-frequency resources and dedicated random access frequency-frequency resources. Dedicated random access time-frequency domain resources refer to random access time-frequency resources determined based on base station indications or default rules. These resources are used only for sending the random access preamble when the request is sent and are not used in traditional random access procedures from idle or inactive states to connected states, nor for purposes such as beam failure recovery or link failure recovery.

[0326] This disclosure provides an information processing method executed by a UE, comprising: during a four-step random access process, sending a dedicated random access preamble to a base station based on dedicated random access time-frequency domain resources; wherein the dedicated random access time-frequency domain resources include time-frequency domain resources specifically used to indicate requests.

[0327] In one embodiment, the dedicated random access time-frequency domain resource can also be a random access time-frequency domain resource used for positioning.

[0328] In this way, a dedicated random access preamble can be sent through dedicated random access time-frequency domain resources, which allows the request to be transmitted on an unoccupied channel, thereby improving the success rate of request transmission.

[0329] In other embodiments, based on the MSG1 of the four-step random access procedure, a request is sent to the base station, including: during the four-step random access procedure, sending a random access preamble to the base station based on dedicated random access time-frequency domain resources; wherein, the dedicated random access time-frequency domain resources include time-frequency domain resources specifically used to indicate the request. The dedicated random access time-frequency domain resources include at least one of dedicated random access time-frequency resources and dedicated random access frequency-frequency resources. Dedicated random access time-frequency domain resources refer to some random access time-frequency resources determined based on base station indication or default rules. These random access time-frequency resources are only used for the random access preamble when sending the request and are not used in traditional random access procedures from idle or inactive states to connected states, nor for purposes such as beam failure recovery or link failure recovery.

[0330] This disclosure provides an information processing method executed by a UE, comprising: during a four-step random access process, sending a random access preamble to a base station based on dedicated random access time-frequency domain resources; wherein the dedicated random access time-frequency domain resources include time-frequency domain resources specifically used to indicate requests.

[0331] In this way, a random access preamble can be sent through a dedicated random access time-frequency domain resource, which is specifically used to indicate the time-frequency domain resource of the request. This also enables the re-request of SRS configuration (i.e., the request to implement SRS reconfiguration). Furthermore, since the request can be indicated through a dedicated time-frequency domain resource, no additional signaling is required, thereby reducing signaling overhead.

[0332] Of course, in other embodiments, the dedicated random access preamble can be replaced by a random access preamble, as long as the random access preamble can be used to indicate a request; and / or, the dedicated random access time-frequency domain resource can also be replaced by a random access time-domain resource. For example, an embodiment of this disclosure provides an information processing method executed by a UE, including: sending a random access preamble to a base station based on MSG1 of a four-step random access procedure, wherein the random access preamble is used to indicate a request.

[0333] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0334] In some embodiments, sending a request to the base station in step S41 based on the MSG3 of the four-step random access procedure includes: sending MSG3 to the base station during the four-step random access procedure, wherein the MSG3 carries the request and / or recommended SRS configuration.

[0335] like Figure 6 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0336] Step S61: During the four-step random access process, MSG3 is sent to the base station, wherein MSG3 carries the requested and / or recommended SRS configuration.

[0337] In some embodiments of this disclosure, the request may be the same as the request described in the above embodiments. For example, the request may be an SRS reconfiguration request.

[0338] In some embodiments, the recommended SRS configuration includes, but is not limited to, at least one of the following: time-domain resource information, frequency-domain resource information, comb parameters, SRS sequence ID, power-related parameters, number of ports, timing advance (TA) information, spatial relation information, and pathloss reference signal information.

[0339] In one embodiment, the time-domain resource information includes, but is not limited to, at least one of the following: period, time slot offset, starting symbol position, number of symbols, and number of retransmissions.

[0340] In one embodiment, the frequency domain resource information includes, but is not limited to, at least one of the following: frequency domain location, frequency domain offset, and frequency hopping.

[0341] In one embodiment, the comb parameter includes, but is not limited to, at least one of the following: comb offset and cyclic shift.

[0342] In one embodiment, the power-related parameters include, but are not limited to, at least one of the following: reference power (P0) and / or adjustment parameter (alpha).

[0343] In one embodiment, a recommended SRS configuration is used to determine the SRS configuration requested for the request (i.e., the SRS configuration configured for the UE). Exemplarily, the recommended SRS configuration is at least partially identical to the SRS configuration (i.e., the SRS configuration configured for the UE). Of course, in other embodiments, the recommended SRS configuration differs from the SRS configuration configured for the UE.

[0344] For example, during the four-step random access process, the UE sends a dedicated random access preamble to the base station based on MSG1 in the four-step random access process. This dedicated random access preamble is used to indicate the request. During the four-step random access process, the UE also sends MSG3, which carries the SRS configuration. Thus, this embodiment can realize the re-request of the SRS configuration, and the MSG3 also carries a recommended SRS configuration, which helps the base station determine the SRS configuration configured for the UE based on the recommended SRS configuration.

[0345] For example, during the four-step random access process, the UE sends a random access preamble to the base station using dedicated random access time-frequency domain resources based on MSG1 in the four-step random access process. These dedicated random access time-frequency domain resources include time-frequency domain resources specifically used to indicate the request. During the four-step random access process, the UE also sends MSG3, which carries the SRS configuration. Thus, this embodiment can achieve a re-request for the SRS configuration, and the MSG3 also carries a recommended SRS configuration, which helps the base station determine the SRS configuration configured for the UE based on the recommended SRS configuration.

[0346] For example, during the four-step random access process, the UE sends MSG3 to the base station, where MSG3 carries a request. Thus, this embodiment can implement a re-request for SRS configuration based on MSG3.

[0347] For example, during the four-step random access process, the UE sends MSG3 to the base station, where MSG3 carries a requested and / or recommended SRS configuration. Thus, this embodiment can implement a re-request for SRS configuration based on MSG3; and since MSG3 also carries the recommended SRS configuration, it is beneficial for the base station to determine the SRS configuration to be configured by the UE based on the recommended SRS configuration.

[0348] In the embodiments of this disclosure, the SRS configuration can be re-requested by MSG1 and / or MSG3 carrying (or indicating) a request and / or carrying a recommended SRS configuration during the four-step random access process, without the need for additional signaling sending requests (or indication requests) and / or sending the recommended SRS configuration, thereby reducing signaling overhead.

[0349] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0350] In some embodiments, sending a request to the base station based on the MSGA of the two-step random access procedure in step S41 includes: sending the MSGA to the base station during the two-step random access procedure; wherein the MSGA carries the request and / or recommended SRS configuration.

[0351] like Figure 7 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0352] Step S71: During the two-step random access process, an MSGA is sent to the base station; wherein the MSGA carries a request and / or recommended SRS configuration.

[0353] In some embodiments of this disclosure, the request may be the same as the request described in the above embodiments. For example, the request may be an SRS reconfiguration request.

[0354] In some embodiments of this disclosure, the recommended SRS configuration may be the SRS configuration recommended in the above embodiments. For example, the recommended SRS configuration may be, but is not limited to, at least one of the following: time-domain resource information, frequency-domain resource information, comb parameters, SRS sequence identifier, power-related parameters, number of ports, timing advance information, spatial relationship information, and path loss reference signal information.

[0355] For example, during the two-step random access process, the UE sends a dedicated random access preamble via the MSGA, whereby the dedicated random access preamble indicates a request; this request is used to request the reconfiguration of the SRS configuration in at least two cells. Thus, this embodiment can achieve the re-request for SRS configuration through the dedicated random access preamble.

[0356] For example, during the two-step random access process, the UE sends a dedicated random access preamble and a recommended SRS configuration via the MSGA; wherein, the dedicated random access preamble is used to indicate a request; this request is used to request the reconfiguration of the SRS configuration in at least two cells. Thus, this embodiment can achieve the re-request of SRS configuration through the dedicated random access preamble, and the MSGA also carries the recommended SRS configuration, thereby helping the base station to determine the SRS configuration to be configured for the UE based on the recommended SRS configuration.

[0357] In the embodiments of this disclosure, the MSGA can carry (or indicate) a request and / or carry the SRS configuration after the two-step random access procedure to achieve a re-request for the SRS configuration, without the need for additional signaling sending requests (or indication requests) and / or sending recommended SRS configurations, thereby reducing signaling overhead.

[0358] In one embodiment, the MSGA may include MSG1 and MSG3. When the MSGA includes MSG1 and MSG3, the description of the SRS configuration for sending requests and / or recommendations by MSG1 and MSG3 during the four-step random access process can be referred to.

[0359] This disclosure provides an information processing method executed by a UE, comprising: receiving MSG2 and / or MSG4 and / or MSGB sent by a base station based on a random access procedure; wherein MSG2 and / or MSG4 and / or MSGB includes a response, and the response includes SRS configuration. Thus, the UE can obtain its SRS configuration in at least two cells based on MSG2 and / or MSG4 and / or MSGB during the random access procedure, thereby facilitating SRS transmission in at least two cells.

[0360] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0361] In other embodiments, the network device is a base station; sending a request to the network device includes: sending an uplink transmission to the base station based on SDT, wherein the uplink transmission carries the request.

[0362] like Figure 8 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0363] Step S81: Based on SDT, send uplink transmission to the base station, wherein the uplink transmission carries a request.

[0364] In some embodiments of this disclosure, the request may be the same as the request in the above embodiments.

[0365] In one embodiment, uplink transmissions based on SDT can be small data packets. It is understood that the data packets that a UE in RRC idle or RRC inactive state needs to transmit are very small; these data packets can be called small data packets. The process of transmitting small data packets can be called small data transmission (SDT). The method by which a UE transmits small data packets using resources configured in the network device can be called configured-grant small data transmission (CG-SDT).

[0366] In one embodiment, the uplink transmission includes a recommended SRS configuration. In some embodiments of this disclosure, the recommended SRS configuration may be the SRS configuration recommended in the above embodiments.

[0367] In some embodiments, step S81, based on SDT, sends an uplink transmission to the base station, including one of the following:

[0368] Based on the random access procedure, the uplink transmission of SDT is sent to the base station;

[0369] Based on the SDT configuration of the network device, the uplink transmission of SDT is sent to the base station.

[0370] like Figure 9 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0371] Step S91: Send uplink SDT to the base station based on the random access procedure; or, send uplink SDT to the base station based on the SDT configuration configured by the network device.

[0372] In some embodiments, the uplink transmission of SDT to the base station based on a random access procedure includes one of the following:

[0373] During the four-step random access process, MSG3 is sent to the base station, where MSG3 carries the uplink transmission of SDT;

[0374] During the two-step random access process, an MSGA is sent to the base station, in which the MSGA carries the uplink transmission of the SDT.

[0375] like Figure 10 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0376] Step S101: In the four-step random access process, MSG3 is sent to the base station, wherein MSG3 carries the uplink transmission of SDT; and / or, in the two-step random access process, MSGA is sent to the base station, wherein MSGA carries the uplink transmission of SDT.

[0377] In some embodiments of this disclosure, the uplink transmission can be the uplink transmission described in the above embodiments. For example, the uplink transmission is the transmission of small data packets. For example, the uplink transmission carries a request, or the uplink transmission carries a request and SRS configuration.

[0378] For example, the UE sends a fractional-packet uplink transmission based on MSG3 of the four-step random access procedure. This uplink transmission carries a request to reconfigure the SRS configuration in at least two cells. Optionally, the uplink transmission also carries a recommended SRS configuration.

[0379] For example, the UE sends an uplink transmission of small data packets based on the MSGA of the two-step random access procedure. This uplink transmission carries a request to reconfigure the SRS configuration in at least two cells. Optionally, the uplink transmission also carries a recommended SRS configuration.

[0380] In this embodiment of the disclosure, uplink transmission of small data packets can be achieved through MSG3 of the four-step random access procedure or MSGA of the two-step random access procedure to send a request for SRS configuration based on the SDT method. Furthermore, this uplink transmission can also carry recommended SRS configurations to recommend the SRS configurations that the base station needs to configure for the UE.

[0381] Of course, in other embodiments, the SRS configuration can also be sent separately in the SDT manner during the random access process; in this case, the transmission of the request can be indicated based on the random access preamble during the random access process.

[0382] For example, the UE sends a dedicated random access preamble based on MSG1 of the four-step random access procedure, which is used to indicate the request; or, the UE sends a random access preamble based on MSG1 of the four-step random access procedure and based on dedicated random access time-frequency domain resources, which include time-frequency domain resources specifically used to indicate the request; the UE sends an uplink transmission of small data packets based on MSG3 of the four-step random access procedure, which includes the recommended SRS configuration.

[0383] For example, the UE sends a dedicated random access preamble based on the MSGA of the two-step random access procedure. This dedicated random access preamble is used to indicate the request. The UE also sends uplink transmissions of small data packets based on the MSGA of the two-step random access procedure. These uplink transmissions include the recommended SRS configuration.

[0384] In this embodiment of the disclosure, requests and / or recommended SRS configurations can be sent via SDT during random access. This enables the re-requesting of SRS configurations and / or the provision of recommended SRS configurations to the base station, while eliminating the need for additional signaling transmission and / or recommended SRS configurations, thereby reducing signaling overhead.

[0385] This disclosure provides an information processing method executed by a UE, comprising: receiving downlink transmissions sent by a base station based on SDT; wherein the downlink transmissions include SRS configuration. Thus, the UE can obtain its SRS configurations in at least two cells based on SDT, thereby facilitating SRS transmission in at least two cells.

[0386] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0404] Thus, in this embodiment of the disclosure, requests and / or recommended SRS configurations can be sent in an SDT-based manner based on the SDT configuration sent by the base station, thereby enabling requests for SRS configurations.

[0405] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0406] In some embodiments, the network device is an LMF; sending a request to the network device includes:

[0407] Send an LTE positioning protocol (LPP) message to the LMF, in which the LPP message carries: a request and / or a recommendation for SRS configuration.

[0409] Step S1201: Send an LPP message to the LMF, wherein the LPP message carries: a request and / or a recommended SRS configuration.

[0410] In embodiments of this disclosure, interaction between the UE and the LMF can be performed via a base station. For example, the UE sending an LPP message to the LMF can be achieved by the UE sending the LPP message through the base station, and the base station forwarding the LPP message to the LMF. This forwarding can be transparent.

[0411] For example, the UE sends an LPP message to the LMF, which carries a request to reconfigure the SRS configuration in at least two cells. Optionally, the LPP message also carries a recommended SRS configuration.

[0412] In this embodiment of the disclosure, the UE can request SRS configuration from the LMF via LPP messages, and can also provide the LMF with recommended SRS configurations, thereby facilitating the LMF to configure SRS for the UE based on the UE's needs. Furthermore, the requested and / or recommended SRS configurations can be carried via LPP messages used for positioning, eliminating the need for additional signaling to carry the requested and / or recommended SRS configurations, thus reducing signaling overhead.

[0413] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0414] like Figure 13 As shown, this disclosure provides an information processing method, executed by a UE, including:

[0415] Step S1301: Receive indication information sent by the network device, wherein the indication information is used to indicate whether to activate or deactivate SRS transmission.

[0416] In one embodiment, the network device is a base station or a core network device.

[0417] In some embodiments of this disclosure, the indication information may be the indication information described in the above embodiments. For example, when the indication information is a first value, it is used to indicate deactivation of SRS transmission; or, if the indication information is a second value, it is used to indicate activation of SRS transmission.

[0418] In one embodiment, the UE receives indication information sent by the network device, which indicates whether to activate or deactivate SRS transmission. Based on the indication information, the UE determines whether to activate or deactivate SRS transmission in at least two cells. For example, if the indication information indicates deactivation of SRS transmission, the UE determines to deactivate SRS transmission in at least two cells; or, if the indication information indicates activation of SRS transmission, the UE determines to activate SRS transmission in at least two cells.

[0419] Thus, in this embodiment of the disclosure, the UE can receive indication information sent by the network device, so as to accurately determine whether the UE's SRS transmission in at least two cells is active or deactivated based on the indication information.

[0420] In some embodiments, receiving indication information sent by the network device in step S1301 includes receiving paging downlink control information (DCI) sent by the network device, wherein the paging DCI carries indication information.

[0422] In one embodiment, the paging DCI can be any format of DCI; for example, the paging DCI can be, but is not limited to, DCI format 1_0; or, the paging DCI can be one of DCI format 0, DCI format 1, DCI format 1A, DCI format 1B, and DCI format 1C; no specific format of the paging DCI is limited here.

[0423] In one embodiment, the paging DCI carries indication information, including one of the following:

[0426] The Short Message Indicator (SMI) field in the paging DCI carries indication information;

[0427] The Short Message field in the paging DCI carries instruction information.

[0428] For example, the first field of the paging DCI carries indication information, which may be an extended field or a new field; or, the second field of the paging DCI carries indication information, which may be a reserved field, a predetermined field, or any field in the paging DCI. For example, a reserved code point in the short message indication information field, or a reserved field in the short message information field, is used to carry indication information.

[0429] Thus, in this embodiment of the disclosure, the UE can obtain indication information through the paging DCI, so as to accurately determine whether SRS transmissions for at least two cells are active or deactivated. Furthermore, the paging DCI can perform both paging and informing the UE of indication information, thereby improving signaling utilization and reducing signaling overhead.

[0430] Furthermore, indication information can be carried in multiple information fields in the paging DCI, thereby enabling various methods of sending indication information through paging messages. This allows for flexible sending of indication information and adaptability to more application scenarios.
