[0035] For ease of understanding, the relevant terms mentioned in this application are introduced herein as follows.

[0036] (1) Cell-free network

[0037] A cell-free massive Multi-Input Multi-Output (MIMO) system can be considered as a deconstruction of the traditional massive MIMO system. In the traditional massive MIMO system, the antennas are centrally distributed at a site (such as a base station), and the UEs are distributed around the base station in the form of cells. In the massive MIMO system, a relatively large number of antennas are deployed at each base station. Therefore, a relatively high array gain and spatial resolution are provided. Multiple UEs can be served simultaneously on the same time-frequency resource, providing high throughput, high reliability, and high energy efficiency.

[0038] The cell-free massive MIMO system breaks the concept of cells. A large number of antennas are distributed dispersedly over a wide area, and UEs are also distributed dispersedly over this wide area. These antennas are called TRPs or access points (APs). In theory, each UE can communicate with each AP. With the help of the fronthaul network and the central processing unit (CPU), a large number of geographically dispersed TRPs can jointly serve a smaller number of UEs, and the CPU uses channel statistical information for joint detection. The cell-free massive MIMO network is expected to be applied to next-generation indoor and hotspot coverage scenarios, such as smart factories, railway stations, shopping malls, stadiums, subways, hospitals, community centers, or university campuses, etc.

[0039] In actual deployment, the cell-free network in a hotspot area can be regarded as a super cell containing multiple TRPs, and multiple TRPs use the same cell identifier (ID). According to the synchronization accuracy and connection relationship between these TRPs, multiple TRPs with high synchronization accuracy can achieve cooperative transmission.

[0040] The channels related to broadcasting in the cell-free network can be implemented according to single frequency networking (SFN) or distributed networking, as Figure 1b , Figure 1c shown. When the number of TRPs in the cell-free network increases and the coverage range expands, the number of synchronization signal block (SSB) beams required will continue to increase, and the resources occupied by the corresponding physical downlink control channel (PDCCH) and physical downlink shared channel (PDSCH) will also continue to increase. Among them, the channels related to broadcasting in the cell-free network can include but are not limited to synchronization channels, random access channels, broadcast PDCCH, PDSCH, etc.

[0041] The technical solutions provided in the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0042] As Figure 2 shown, it is a schematic flowchart of a communication method 200 provided by an exemplary embodiment of the present application. The method 200 can be, but is not limited to, executed by a terminal, and can be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 can at least include the following steps.

[0043] S210, the terminal sends a first signal to the network-side device.

[0044] Among them, considering scenarios such as cell-free or future large cells, the solutions provided in the related art for location updates, uplink positioning, etc. at the cell granularity are no longer applicable. For example, for cell-free or future large cells, even if the position or position change of the terminal within the cell, the network-side device needs to be aware, so as to obtain more accurate terminal position information or uplink positioning, in order to determine a suitable or matching network node, paging cell, etc. for the terminal, and ensure the performance of the communication system. Among them, the "cell-free" can be understood as a cell without cell network coverage, such as a particularly large cell or a network coverage area without the concept of a cell.

[0045] In response to this, in this application, the terminal sends a first signal to the network-side device, where the first signal is used for at least one of indicating terminal position information, indicating terminal position change information, and uplink positioning, so that the network-side device can determine terminal position information, determine terminal position change information, perform uplink positioning, etc. based on the first signal, and determine a suitable or matching network node and paging cell for the terminal according to the determined terminal position information, terminal position change information, uplink positioning result, etc., to ensure the performance of the communication system. In this embodiment, the terminal position change information can be determined according to the terminal position information.

[0046] It can be understood that the terminal's indication to the network-side device of its position or position change within the cell is no longer limited to cell handover or cell group handover, so that the network-side device can more flexibly determine terminal position information, determine terminal position change information, perform uplink positioning, etc. based on the first signal, and timely determine a suitable or matching network node, paging cell, etc. for the terminal according to the determined terminal position information, terminal position change information, uplink positioning result, etc., to ensure the performance of the communication system.

[0047] In some embodiments, there can be various ways for the terminal to determine the first signal. For example, the terminal can determine the first signal according to the indication method of the terminal position information or terminal position change information, etc.

[0048] For example, in the case of explicitly indicating the terminal position information or terminal position change information, the first signal can be, but is not limited to, a signal that can directly carry the terminal position information or terminal position change information.

[0049] For the case of implicitly indicating the terminal location information or the terminal location change information, the first signal may be a signal directly indicating the terminal location information or the terminal location change information. For example, the first signal may be, but is not limited to, at least one of a sounding reference signal (SRS), a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), an uplink notification, and a wake-up signal.

[0050] Among them, for the PUSCH, the location information or the location change information of the terminal may be indicated on the PUSCH by using, for example, a medium access control (MAC) control element (MAC CE), etc.

[0051] For the PUCCH, a special PUCCH format may be used to indicate the terminal location information or the terminal location change information.

[0052] For the uplink notification, it may be dedicated to the indication of the terminal location information, the indication of the terminal location change information, and uplink positioning, or it may also multiplex other uplink notifications. For example, it may multiplex the uplink notification for feedback on specific downlink information, and there is no limitation here.

[0053] For the wake-up signal, when the terminal wakes up some on-demand synchronization signal blocks (SSBs), the coverage area corresponding to the SSB is the terminal location information indicated by the terminal, etc. It can be understood that the "SSB" mentioned in the context of this application may also be any signal including a synchronization signal, a broadcast signal, a broadcast channel, other system messages, or a downlink broadcast channel.

[0054] In some other embodiments, for the case where the first signal is used for the uplink positioning, the first signal may also be, but is not limited to, at least one of SRS, PRACH, PUSCH, PUCCH, uplink notification, and wake-up signal.

[0055] Based on this, as a possible implementation, the first signal may be sent by the terminal when a predetermined trigger condition is met. Among them, the predetermined trigger condition may be, but is not limited to, a periodic trigger condition, an event trigger condition, etc. configured by means of pre-configuration, protocol agreement, etc.

[0056] For example, if the predetermined trigger event is a periodic trigger condition, then the terminal may send the first signal to the network-side device at the transmission period of the first signal.

[0057] Again, for example, if the predetermined trigger condition is an event trigger condition, then the terminal may send the first signal to the network-side device when a first condition is met. The first condition may include, but is not limited to, at least one of the following items 11)-18). Herein, the first condition is the event trigger condition.

[0058] 11) The terminal has switched, reselected, or changed the target object.

[0059] 12) The terminal expects to switch, reselect, or change to the target object.

[0060] For the aforementioned 11)-12), the target object may include, but is not limited to, at least one of a network node, a network node group, a cell, a cell group, a RAN, and a RAN group. The network node may be, but is not limited to, a TRP, an AP, etc.

[0061] For example, taking a network node and a network node group as an example, if the terminal switches, reselects, or changes from the current network node to another network node, the terminal switches, reselects, or changes from the current network node to a network node in another network node group, the terminal expects to switch, reselect, or change from the current network node to another network node, the terminal expects to switch, reselect, or change from the current network node to a network node in another network node group, etc., then the terminal may send the first signal to the network-side device.

[0062] It should be noted that the network node mentioned in this application and the network-side device receiving the first signal may be the same or different.

[0063] 13) The terminal fails to select a downlink signal that meets the requirements.

[0064] Herein, the "requirements" may be measurement requirements, positioning requirements, etc.

[0065] For example, assuming that the "requirements" are measurement requirements, then, when the terminal performs downlink measurement and finds that the signal quality or signal energy of all downlink signals is lower than a certain threshold, the terminal may send the first signal to the network-side device to indicate the terminal location information, terminal location change information, etc. At the same time, the network-side device may be notified through the first signal to turn on the auxiliary downlink signal or increase the power of the downlink signal or turn on some TRPs near the terminal location, etc., to ensure the continuity of the terminal signal measurement service.

[0066] 14) The terminal detects abnormal Timing Advance (TA) information.

[0067] Among them, the abnormal TA information may be, but is not limited to, at least one of the following a)-c).

[0068] a) The change amount of TA detected by the terminal exceeds the fourth threshold, or the TA detected by the terminal exceeds the fifth threshold.

[0069] b) The change amount of the reference signal received power (RSRP) of the same downlink reference signal detected by the terminal at two specific time points is not less than or exceeds the fifth threshold.

[0070] Among them, the specific time points can be implemented by means such as protocol agreement, high-layer configuration, default configuration, etc., and the two specific time points can be two adjacent time points, two specific time points for signal measurement, etc., which are not limited here.

[0071] c) The change amount of the RSRP of the downlink reference signal measured by the terminal at two time points is not less than or exceeds the sixth threshold.

[0072] Among them, the time points can be implemented by means such as protocol agreement, high-layer configuration, default configuration, etc., and the two time points can be two adjacent time points, two specific time points for signal measurement, etc., which are not limited here.

[0073] 15) The change amount of the moving speed of the terminal is not less than the first threshold.

[0074] For example, the change amount of the moving speed of the terminal in a certain direction over a period of time is not less than or exceeds the first threshold, or the change amount of the moving speed of the terminal between specific times is not less than or exceeds the first threshold.

[0075] Among them, the specific time can be implemented by means such as protocol, high-layer configuration, default configuration, etc., which are not limited here.

[0076] 16) The estimated Round-Trip Time (RTT) or the change amount of RTT of the terminal is not less than the second threshold.

[0077] 17) The change amount of the terminal position information estimated by the terminal based on the downlink signal is not less than the third threshold.

[0078] Among them, the downlink signal may be, but is not limited to, the downlink positioning reference signal (Positioning Reference Signal, PRS) or SSB, etc.

[0079] For example, when the change amount of the terminal location information estimated based on the downlink PRS or SSB from different network nodes (such as TRP) is not less than a third threshold, the terminal may send a first signal to the network device.

[0080] 18) The terminal receives a request for reporting the location information of the terminal sent by the network device.

[0081] It can be understood that for cell-free or future large cells, by configuring event-triggered conditions for sending the first signal, the resource overhead and signal transceiver complexity during the transceiver of the first signal can be effectively reduced.

[0082] In addition, the aforementioned first threshold, second threshold, third threshold, fourth threshold, fifth threshold, sixth threshold, etc. can be implemented by protocol agreement, high-layer configuration, or network-side configuration, which is not limited herein.

[0083] In this embodiment, by the terminal sending a first signal to the network device for at least one of indicating the terminal location information, indicating the terminal location change information, and uplink positioning, the network device can clearly know the location or location change of the terminal, so as to determine a suitable or matching network node, paging cell, etc. for the terminal, thereby ensuring the performance of the communication system.

[0084] Such as Figure 3 As shown, it is a schematic flowchart of a communication method 300 provided by an exemplary embodiment of the present application. The method 200 may but is not limited to be executed by a terminal, and may specifically be executed by hardware or software installed in the terminal. In this embodiment, the method 300 may at least include the following steps.

[0085] S310, the terminal sends a first signal to the network device.

[0086] Wherein, the first signal is used for at least one of indicating the terminal location information, indicating the terminal location change information, and uplink positioning, and the terminal location change information is determined according to the terminal location information.

[0087] It can be understood that the implementation process of S310 may refer to the relevant descriptions in the foregoing method embodiment 200. Of course, in addition to referring to the relevant descriptions in the foregoing method embodiment 200, as a possible implementation manner, please refer again to Figure 3 , the process of the terminal sending a first signal to the network device may be as Figure 3 shown, and the content is as follows.

[0088] S311, the terminal determines a first transmission resource based on the terminal location information and a preset association relationship.

[0089] Based on this, the preset association relationship includes the association relationship between the first transmission resource and the terminal location information, so that the terminal can determine the first transmission resource for the first signal transmission according to the detected terminal location information or terminal location change information and send it.

[0090] Correspondingly, after receiving the first signal sent by the terminal, the network-side device can also determine the terminal location information or terminal location information of the terminal that sent the first signal by determining the first transmission resource that transmits the first signal, so as to realize the indication of the terminal location information, the indication of the terminal location change information, etc.

[0091] Optionally, in some embodiments, the terminal location information may include, but is not limited to, at least one of the information of the first area, the information of the second area, the information of the cell-free coverage area, the information of the tracking area, and the information of the radio access network (RAN) area.

[0092] Among them, the first area is the area covered by a network node or a group of network nodes. Based on this, the preset association relationship may be the association relationship between the first transmission resource and the network node or the group of network nodes.

[0093] The second area corresponds to the identifier of the downlink reference signal. For example, the terminal location information is represented by the identifier or index of a certain downlink reference signal.

[0094] The RAN area is the basis for device tracking at the radio access network level. Among them, a terminal in an inactive state can be assigned a RAN notification area, which can be composed of any one of a cell ID list, a RAN area identity (RAI) list, and a tracking area identity (TAI) list. Among them, the cell IID list

[0095] The tracking area is the basis for core network-level device tracking. The core network assigns a terminal registration area to each device, and this area is composed of a list of tracking area identifiers.

[0096] Based on this, in this application, there can be various ways to represent the terminal location information. For example, direct representation or indirect representation, etc.

[0097] For example, when directly representing the terminal location information, the terminal location information may include, but is not limited to, at least one of the following 21)-24).

[0098] 21) Coordinate position information with a preset position as the origin.

[0099] Among them, the preset position can be implemented by means such as protocol agreement, network - side configuration, and terminal self - determination.

[0100] In this embodiment, according to different coordinate systems, the coordinate position information can be different. For example, the coordinate position information can be a two - dimensional grid in a two - dimensional coordinate system with the preset position as the origin as shown in Figure 4 the figure, or a three - dimensional grid in a three - dimensional coordinate system with the preset position as the origin, or the position information of a certain sub - region in a polar coordinate system with the preset position as the origin.

[0101] It should be noted that for the case where the terminal position information is represented by the coordinate position information with the preset position as the origin, the representation form or format of the terminal position information can be determined by means such as protocol agreement, the terminal self - determining and then sending it to the network - side device, or the network - side device instructing the terminal.

[0102] The representation form or format of the terminal position information can include but is not limited to the determination method of the preset position, the size of the grid in the two - dimensional coordinate system, the size of the grid in the three - dimensional coordinate, the size of a certain sub - region in the polar coordinate, etc., which are not limited here.

[0103] 22) Latitude and longitude information.

[0104] 23) Position information relative to a reference point. Among them, the reference point can be determined by means such as protocol agreement and network - side indication. For example, it can be determined by means such as protocol agreement and network - side indication that the previous or last reported terminal position information is used as the reference point.

[0105] 24) Position change information.

[0106] It can be understood that using the direct representation methods described in the foregoing 21) - 24) to represent the terminal position information can improve the convenience of querying the preset association relationship.

[0107] Also, for example, when the terminal position information is not directly represented, the non - direct representation methods can include at least one of the following 31) - 33).

[0108] 31) Quantitatively represent the directly represented terminal position information.

[0109] For example, taking the directly represented information as latitude and longitude information as an example, the continuous latitude and longitude information can be quantified according to a predetermined granularity to obtain the non - directly represented terminal position information. Among them, the predetermined granularity can be 100m, 1km, etc., which are not limited here.

[0110] 32) An identifier of a network node or an identifier of a group of network nodes, where the network node may be a TRP, an AP, etc.

[0111] That is, the network node or the area covered by the network node is the terminal location information.

[0112] 33) An index of a downlink reference signal, where the index of the downlink reference signal is visible to the terminal, and the area positions corresponding to different downlink reference signals are different. Optionally, the downlink reference signal includes an SSB, etc.

[0113] For example, the terminal may first measure and determine one or more associated downlink reference signals, and represent the terminal location information of the terminal by the identifier of the downlink reference signal whose RSRP is higher than the seventh threshold.

[0114] It can be understood that using a non-direct representation method to represent the terminal location information can reduce the overhead and avoid the privacy leakage problem caused by overly precise positions.

[0115] In some embodiments, in addition to the association relationship between the foregoing first transmission resource and the terminal location information, the preset association relationship may further include the association relationship between the first transmission resource and the terminal information. Thus, for an idle terminal or an inactive state terminal, etc., after the terminal sends a first signal based on the association relationship between the first transmission resource and the terminal information, the network side device can accurately determine the sender of the first signal according to the association relationship between the first transmission resource and the terminal information, thereby ensuring the reliability of subsequent communications.

[0116] Optionally, the terminal information may include at least one of the following 41)-44).

[0117] 41) Some or all of the identifiers of the terminal.

[0118] 42) Some or all of the Radio Network Temporary Identifiers (RNTIs) of the terminal.

[0119] 43) Some or all of the International Mobile Subscriber Identities (IMSIs) of the terminal.

[0120] 44) Some or all of the Temporary Mobile Subscriber Identity (TMSI) of the terminal.

[0121] S312, send the first signal to the network-side device based on the first transmission resource.

[0122] In some other embodiments, the foregoing first transmission resource may be a time-frequency resource, a Demodulation Reference Signal (DMRS) resource, sequence-related information, etc. In this embodiment, the first transmission resource may be implemented by means of protocol agreement, high-layer configuration, network-side configuration, etc.

[0123] For example, in the case where the first transmission resource is configured by the network-side device, the network-side device may send a second signal to the terminal. Correspondingly, the terminal receives the second signal sent by the network-side device; wherein, the first transmission resource is carried in the second signal.

[0124] Optionally, the second signal may include but is not limited to at least one of a first signaling, a broadcast message, and a physical layer signaling.

[0125] Among them, the first signaling can be understood as dedicated to the configuration of the first transmission resource. For example, a dedicated SRS resource set can be configured for a connected terminal through a dedicated Radio Resource Control (RRC) signaling, etc., for dedicatedly sending a first signal to the network-side device. Among them, the first transmission resource belongs to the SRS resource set. Among them, the SRS resource set may include but is not limited to a port or an SRS occasion, an SRS time-frequency position, etc.

[0126] The broadcast message may be but is not limited to a System Information Block (SIB), etc. For example, an SRS resource set can be configured through a broadcast message such as SIB1, where the first transmission resource belongs to the SRS resource set.

[0127] The physical layer signaling may be, but is not limited to, Downlink Control Information (DCI), etc. In this embodiment, the first transmission resource may be dynamically scheduled by the physical layer signaling to trigger the terminal to send the first signal. For example, when the network-side device detects that the measurement quality reported by the terminal is less than or does not exceed a certain threshold, the network-side device may dynamically use the physical layer signaling, such as a PDCCH sequence (order), to instruct the terminal to send the corresponding location reporting first signal. At this time, the first transmission resource when reporting the first signal may be specified or configured by the PDCCH order.

[0128] In some embodiments, the first transmission resource may be independently configured from the second transmission resource. That is, the network-side device may independently configure the first transmission resource without sharing it with the transmission resources of other signals, thereby obtaining greater transmission flexibility. Herein, the second transmission resource is other transmission resources except the first transmission resource.

[0129] Alternatively, the first transmission resource may also be a shared resource or a common resource with the second transmission resource; that is, the network-side device may configure a shared resource for the transmission of the first signal and other signals except the first signal, thereby reducing the signaling overhead during resource configuration.

[0130] Based on this, if the first transmission resource is independently configured from the second transmission resource, then the first transmission resource and the second transmission resource may satisfy at least one of the following 51)-54).

[0131] 51) The Cyclic Prefix (CP) used by the first signal is greater than the CP used by the third signal, where the third signal is other signals except the first signal.

[0132] For example, relative to the third signal, the first signal may use an extended CP to tolerate greater signal errors.

[0133] 52) The first time-domain resource where the first signal is located is within the gap between the resources included in the second time-domain resource. That is, the time-frequency resource where the first signal is located is reserved within a gap between the second time-domain resources. Herein, the first time-domain resource belongs to the first transmission resource, and the second time-domain resource belongs to the second transmission resource.

[0134] 53) The first frequency-domain resource where the first signal is located is independent of the second frequency-domain resource. The first frequency-domain resource belongs to the first transmission resource, and the second frequency-domain resource belongs to the second transmission resource.

[0135] There is a gap between the first frequency-domain resource where the first signal is located and the second frequency-domain resource. That is, the frequency-domain resource where the first signal is located is separated from the frequency resources of other signals and maintains a certain gap.

[0136] It should be noted that through the designs of the foregoing 51)-54), reliable transmission of the first signal can also be achieved when the TA of the first signal is not indicated.

[0137] If the first transmission resource and the second transmission resource are shared resources or common resources, the resource sharing method between the first transmission resource and the second transmission resource includes at least one of the following 61)-64).

[0138] 61) Time division multiplexing (TDM).

[0139] For example, assuming that the first signal and the third signal are both SSBs, then the TDM of each SSB has different transmission resources.

[0140] 62) Frequency Division multiplexing (FDM).

[0141] For example, assuming that the first signal and the third signal are both SSBs, then the FDM of each SSB has different transmission resources.

[0142] 63) Determine the first transmission resource and the second transmission resource in a predetermined order, where the predetermined order includes at least one of first in the frequency domain and then in the time domain, and first in the time domain and then in the frequency domain.

[0143] For example, assuming that the first signal and the third signal are both SSBs, then the transmission resources of each SSB can be determined in the order of first the frequency domain and then the time domain.

[0144] 64) The first transmission resource and the second transmission resource overlap in time-frequency resources.

[0145] For example, assuming that the common resource is the PRACH resource, then when sending a random access signal, a part of the preamble sequence can be specifically allocated on a random access occasion (RO) as the transmission resource of the first signal, that is, the first transmission resource. Here, the part of the preamble can be divided by SSB as the granularity.

[0146] Based on this, as a possible implementation, after the configuration of the first transmission resource is completed, there can be various ways to configure the preset association information implemented based on the first transmission resource. For example, it can be configured in the terminal and the network-side device through protocol agreement, high-layer configuration, network-side device indication, terminal autonomous determination, etc., so that the terminal and the network-side device have a consistent understanding of the preset association relationship.

[0147] For example, assuming that the preset association is indicated by the network-side device, then when the network-side device sends the first transmission resource through the second information, it can also indicate the preset association relationship, etc., which is not limited here.

[0148] Another example, assuming that the preset association relationship is determined by the terminal, in order to ensure that the terminal and the network-side device have a consistent understanding of the preset association relationship, the terminal can indicate the preset association relationship to the network-side device in an explicit or implicit manner.

[0149] Among them, assuming that the preset association relationship is indicated to the network-side device in an explicit manner, then a channel with relatively more transmission bits (such as PUSCH, PUCCH, etc.) can be used to indicate the preset association relationship, and the terminal location information in the preset association relationship is represented by a direct representation method.

[0150] Assuming that the preset association relationship is indicated to the network-side device in an implicit manner, then a channel with relatively fewer transmission bits (such as reference signal, preamble, etc.) can be used to indicate the preset association relationship, where the terminal location information in the preset association relationship is represented by an indirect representation method; or, the determination rule of the preset association relationship can also be indicated to the network-side device, such as mapping the order of information id to the order of resource time-frequency domain sequence, etc.

[0151] It should be noted that for the terminal and the network-side device, the two have a consistent understanding of the preset association relationship, so as to ensure the consistency of the understanding of the terminal location information.

[0152] In some embodiments, when the terminal sends the first signal, in addition to considering the first transmission resource, the first condition, etc., if the first signal is used for uplink positioning, then the terminal can also send the first signal to the network-side device according to the positioning configuration information.

[0153] Among them, the positioning configuration information may include at least one of a signal transmission period, a signal transmission time offset, and uplink positioning trigger information.

[0154] The above-mentioned uplink positioning trigger information can be periodic trigger information, event trigger information, etc. For example, the network can request when the terminal sends the first signal (i.e., the uplink positioning signal) for uplink positioning.

[0155] Optionally, the positioning configuration information can be implemented by means of protocol agreement, high-layer configuration, network-side configuration, etc. For example, when the positioning configuration information includes the transmission period and the signal transmission time offset, the positioning configuration information can be included in the first transmission resource and configured by the second signal; for another example, when the positioning configuration information includes the above-mentioned uplink positioning trigger information, the positioning configuration information can be included in the first condition and configured by the network-side device, etc. This application does not limit this.

[0156] This application proposes a method for tracking the terminal position based on the first signal, enabling the network-side device to more accurately update the terminal position information, determine the terminal position information, or perform uplink positioning on the basis of introducing a certain amount of uplink signaling overhead.
