[0057] The joint channel estimation method and device proposed in the present disclosure mainly solve the following problems:

[0058] First, whether the maximum duration is reported by the terminal device and how to report the maximum duration;

[0059] Second, the relationship between the maximum duration and the time window length, whether and how to determine the time window length based on the maximum duration;

[0060] Third, the signaling process for reporting the maximum duration length and the time window length is to configure the time window length first, or to report the maximum duration length first.

[0061] The joint channel estimation method and apparatus thereof according to the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0062] Figure 1 A schematic flow chart of a joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method may be executed by a terminal device.

[0063] The terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may be different. For example, in a 5G system, the terminal device may be called UE (User Equipment). The wireless terminal device may communicate with one or more CNs (Core Networks) via RAN. The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with a wireless access network.

[0064] For example, the terminal device may be a PCS (Personal Communication Service) phone, a cordless phone, a SIP (Session Initiated Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), etc. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, which is not limited in the embodiments of the present disclosure.

[0065] like Figure 1 As shown, the joint channel estimation method may include the following steps:

[0066] Step 101, determining the maximum duration length of the terminal device.

[0067] In the embodiment of the present disclosure, the maximum duration length refers to the maximum duration length for which the terminal device maintains power consistency and phase consistency.

[0068] In the embodiment of the present disclosure, the terminal device can detect the maximum duration length corresponding to itself.

[0069] Step 102: Determine a reporting strategy for the maximum duration.

[0070] In an embodiment of the present disclosure, the reporting strategy of the maximum duration length may include the terminal device not reporting the maximum duration length, and the terminal device reporting the maximum duration length, wherein reporting the maximum duration length may include the terminal device periodically reporting the maximum duration length, and the terminal device non-periodically reporting the maximum duration length.

[0071] Step 103: Determine the actual time window length according to the reporting strategy and the maximum duration length.

[0072] In the embodiments of the present disclosure, the actual time domain window length refers to the time domain length actually used by the terminal device when performing joint channel estimation processing. It should be understood that the actual time domain window length should be less than or equal to the maximum duration length.

[0073] In the embodiment of the present disclosure, the terminal device can determine the actual time window length according to the reporting strategy and the maximum duration length.

[0074] Step 104: Perform joint channel estimation processing according to the actual time window length.

[0075] In the embodiment of the present disclosure, after determining the actual time window length, the terminal device can perform joint channel estimation processing according to the actual time window length.

[0076] The joint channel estimation method of the embodiment of the present disclosure determines the maximum duration length of the terminal device and determines the reporting strategy of the maximum duration length, determines the actual time window length according to the reporting strategy and the maximum duration length, and performs joint channel estimation processing according to the actual time window length. Thus, it is possible to determine the actual time window length according to the maximum duration length and the reporting strategy of the terminal device, so that the terminal device can perform joint channel estimation processing according to the actual time window length.

[0077] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0078] The present disclosure provides another joint channel estimation method. Figure 2 A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a terminal device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0079] like Figure 2 As shown, the joint channel estimation method may include the following steps:

[0080] Step 201, determining the maximum duration length of the terminal device.

[0081] In the embodiment of the present disclosure, step 201 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0082] Step 202: Determine that the reporting policy for the maximum duration length is that the terminal device does not report the maximum duration length.

[0083] Step 203: Determine the actual time window length according to the maximum duration length and the configured nominal time window length.

[0084] In the embodiment of the present disclosure, the nominal time domain window length (Nominal time domain window) is the configured time window length.

[0085] In a possible implementation manner of the embodiment of the present disclosure, the nominal time window length may be explicitly configured by a network device.

[0086] The network equipment takes a base station as an example. The base station may include multiple cells that provide services for UE (User Equipment). Depending on the specific application scenario, each cell may include multiple TRPs (Transmission Reception Point or Transmit Receive Point), each TRP may include one or more antenna panels, or may be a device in the access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. For example, the base station involved in the embodiments of the present disclosure may be a BTS (Base Transceiver Station) in GSM (Global System for Mobile communications) or CDMA (Code Division Multiple Access), or a base station (NodeB) in WCDMA (Wide-band Code Division Multiple Access), or an evolved Node B (eNB or e-NodeB for short) in an LTE (long term evolution) system, or a 5G base station (gNB for short) in a 5G network architecture (next generation system), or a HeNB (Home evolved Node B), a relay node, a femto, a pico, etc., but is not limited in the embodiments of the present disclosure.

[0087] As an example, the network device may configure the nominal time window length through RRC (Radio Resource Control) configuration information.

[0088] As another example, the network device may configure the nominal time window length through MAC-CE (Medium Access Control-Control Element).

[0089] As another example, the network device may configure the nominal time window length through DCI (Downlink Control Information, downlink control information).

[0090] It should be noted that the above is only an example of a network device configuring a nominal time window length through a signaling. In actual application, the nominal time window length can also be configured through a combination of multiple signalings, and the present disclosure does not limit this. For example, the nominal time window length can be configured through a combination of any two of the above three signalings, or the nominal time window length can also be configured through the above three signalings.

[0091] In another possible implementation manner of the embodiment of the present disclosure, the nominal time window length may also be obtained according to a protocol.

[0092] As an example, the estimated time window length agreed upon by the protocol is M, that is, the nominal time window length is agreed upon by the protocol to be M.

[0093] In another possible implementation manner of the embodiment of the present disclosure, the nominal time window length may also be obtained implicitly.

[0094] As an example, the time window length may be implicitly determined by the uplink and downlink frame structure ratio, that is, the nominal time window length may be implicitly determined by the uplink and downlink frame structure ratio.

[0095] In the embodiment of the present disclosure, the actual time window length may be determined according to the maximum duration length and the configured nominal time window length.

[0096] It should be understood that the actual time window length should be less than or equal to the maximum duration length. Therefore, in the embodiments of the present disclosure, the nominal time window length can be compared with the maximum duration length. When the nominal time window length is less than or equal to the maximum duration length, the nominal time window length can be used as the actual time window length. When the nominal time window length is greater than the maximum duration length, the maximum duration length can be used as the actual time window length.

[0097] Step 204: perform joint channel estimation processing according to the actual time window length.

[0098] In the embodiment of the present disclosure, step 204 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0099] An example is given with the nominal time window length configured for a network device, such as Figure 3 As shown, the network device can enable the joint channel estimation mechanism, that is, the network device can send the joint channel estimation enabling information and configure the nominal time window length as M. When the terminal device receives the joint channel estimation enabling information and the nominal time window length M sent by the network device, the terminal device can check the maximum duration length N corresponding to itself. If the terminal device determines that M≤N, the terminal device can perform joint channel estimation with M as the window length, and if the terminal device determines that M>N, the actual time window length M'=N is automatically adjusted, and the joint channel estimation is performed with M' as the window length.

[0100] It should be noted that the above only uses the triggering mode of joint channel estimation as an explicit trigger (i.e., the network device sends the joint channel estimation enabling information) as an example, wherein the explicit triggering means indicated by special signaling and bits. In actual application, the triggering mode of joint channel estimation can also be an implicit triggering, for example, when the network device only sends the nominal time window length, the joint channel estimation is triggered by default. Alternatively, when the network device receives the maximum duration length report from the terminal device, the joint channel estimation is triggered, or, when a certain protocol predefined rule is met, the joint channel estimation is triggered by default.

[0101] The joint channel estimation method of the embodiment of the present disclosure determines that the reporting strategy of the maximum duration length is that the terminal device does not report the maximum duration length, determines the actual time window length according to the maximum duration length and the configured nominal time window length, and performs joint channel estimation processing according to the actual time window length. Therefore, in the case where the terminal device does not report the maximum duration length, the actual time window length can be determined according to the maximum duration length of the terminal device and the configured nominal time window length, so that the terminal device can perform joint channel estimation processing according to the actual time window length.

[0102] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0103] The present disclosure provides another joint channel estimation method. Figure 4A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a terminal device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0104] like Figure 4 As shown, the joint channel estimation method may include the following steps:

[0105] Step 301, determining the maximum duration length of the terminal device.

[0106] In the embodiment of the present disclosure, step 301 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0107] Step 302, determining the reporting strategy of the maximum duration length is that the terminal device always periodically reports the maximum duration length.

[0108] Step 303: Always periodically report the maximum duration length.

[0109] In the embodiment of the present disclosure, the terminal device may always periodically report its corresponding maximum duration length.

[0110] Step 304, after the joint channel estimation mechanism is enabled, the nominal time window length is used as the actual time window length, wherein the terminal device receives the nominal time window length; the nominal time window length is determined based on the maximum duration length, and the nominal time window length is less than or equal to the maximum duration length.

[0111] In an embodiment of the present disclosure, the network device may configure a nominal time window length according to the maximum duration length, wherein the nominal time window length configured by the network device should be less than or equal to the maximum duration length. The network device may send the configured nominal time window length to the terminal device, for example, the network device may configure the nominal time window length through RRC, MAC-CE or DCI.

[0112] In an embodiment of the present disclosure, after the joint channel estimation mechanism is enabled, if the terminal device receives a nominal time window length, the terminal device may use the nominal time window length as the actual time window length.

[0113] Step 305: Use the maximum duration length as the actual time window length, wherein the terminal device does not receive the nominal time window length.

[0114] In an embodiment of the present disclosure, when the terminal device does not receive the nominal time window length sent by the network device, the maximum duration length may be used as the actual time window length.

[0115] Step 306: Perform joint channel estimation processing according to the actual time window length.

[0116] In the embodiment of the present disclosure, step 306 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0117] As an application scenario, regardless of whether the network device triggers joint channel estimation, the terminal device periodically reports the maximum duration length.

[0118] like Figure 5 As shown, the terminal device can always periodically report the maximum duration length N. After the network device receives the maximum duration length N reported by the terminal device, it can determine whether to enable the joint channel estimation mechanism (that is, determine whether to trigger the joint channel estimation). If the network device enables the joint channel estimation mechanism and sends down the time window configuration, the terminal device can perform joint channel estimation with M as the window length after receiving the nominal time window length M sent by the network device. If the terminal device does not receive the nominal time window length sent by the network device, the terminal device implicitly obtains the actual time window length as N, and performs joint channel estimation with N as the window length.

[0119] The joint channel estimation method of the embodiment of the present disclosure determines that the reporting strategy of the maximum duration length is that the terminal device always periodically reports the maximum duration length, and always periodically reports the maximum duration length; after the joint channel estimation mechanism is enabled, the nominal time window length is used as the actual time window length, wherein the terminal device receives the nominal time window length; or, the maximum duration length is used as the actual time window length, wherein the terminal device does not receive the nominal time window length; and the joint channel estimation process is performed according to the actual time window length. Thus, in the case where the terminal device always periodically reports the maximum duration length, the terminal device can perform the joint channel estimation process according to the received nominal time window length, or, when the nominal time window length is not received, the terminal device can perform the joint channel estimation process according to the maximum duration length.

[0120] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0121] The present disclosure provides another joint channel estimation method. Figure 6A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a terminal device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0122] like Figure 6 As shown, the joint channel estimation method may include the following steps:

[0123] Step 401, determining the maximum duration length of the terminal device.

[0124] In the embodiment of the present disclosure, step 401 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0125] Step 402, determining the reporting strategy of the maximum duration length is that after the joint channel estimation mechanism is enabled, the terminal device periodically reports the maximum duration length.

[0126] In the embodiment of the present disclosure, the terminal device may periodically report the maximum duration length after the joint channel estimation mechanism is enabled. That is, the terminal device may periodically report the maximum duration length after the network device enables the joint channel estimation mechanism.

[0127] Step 403: After the joint channel estimation mechanism is enabled, the maximum duration length is periodically reported.

[0128] Step 404, taking the nominal time window length as the actual time window length, wherein the terminal device receives the nominal time window length sent by the network device; wherein the nominal time window length is determined based on the maximum duration length, and the nominal time window length is less than or equal to the maximum duration length.

[0129] In an embodiment of the present disclosure, when the network device receives the maximum duration length reported by the terminal device, the network device may configure the nominal time window length according to the maximum duration length, wherein the nominal time window length configured by the network device is less than or equal to the maximum duration length. The network device may send the configured nominal time window length to the terminal device, for example, the network device may configure the nominal time window length through RRC, MAC-CE or DCI.

[0130] In an embodiment of the present disclosure, when receiving the nominal time window length, the terminal device may use the nominal time window length as the actual time window length.

[0131] Step 405: Use the maximum duration length as the actual time window length, wherein the terminal device does not receive the nominal time window length.

[0132] In an embodiment of the present disclosure, when the terminal device does not receive the nominal time window length sent by the network device, the maximum duration length may be used as the actual time window length.

[0133] Step 406: Perform joint channel estimation processing according to the actual time window length.

[0134] In the embodiment of the present disclosure, step 406 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0135] As an application scenario, after the network device enables the joint channel estimation mechanism, the terminal device periodically reports the maximum duration length.

[0136] like Figure 7 As shown, after the network device enables the joint channel estimation mechanism, the terminal device can periodically report the maximum duration length N. The terminal device can check whether it has received the nominal time window length M configured by the network device. If it has received it, the joint channel estimation is performed with M as the window length. If it has not received it, the terminal device implicitly obtains the actual time window length as N, and performs the joint channel estimation with N as the window length. If the network device terminates the joint channel estimation, the terminal device stops periodically reporting the maximum duration length.

[0137] The joint channel estimation method of the embodiment of the present disclosure determines that after the joint channel estimation mechanism is enabled, the terminal device periodically reports the maximum duration length; after the joint channel estimation mechanism is enabled, the maximum duration length is periodically reported; the nominal time window length is used as the actual time window length, wherein the terminal device receives the nominal time window length; or the maximum duration length is used as the actual time window length, wherein the terminal device does not receive the nominal time window length; and the joint channel estimation process is performed according to the actual time window length. Thus, after the joint channel estimation mechanism is enabled, the terminal device can periodically report the maximum duration length and perform the joint channel estimation process according to the received nominal time window length, or, when the nominal time window length is not received, the terminal device can perform the joint channel estimation process according to the maximum duration length.

[0138] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0139] The present disclosure provides another joint channel estimation method. Figure 8 A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a terminal device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0140] like Figure 8 As shown, the joint channel estimation method may include the following steps:

[0141] Step 501, determining the maximum duration length of the terminal device.

[0142] In the embodiment of the present disclosure, step 501 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0143] Step 502, determining the reporting strategy of the maximum duration length is that when the maximum duration length is greater than or equal to the configured nominal time window length, the terminal device non-periodically reports the maximum duration length.

[0144] It should be noted that the above Figure 2 The explanation of the nominal time window length in the embodiment is also applicable to this embodiment and will not be repeated here.

[0145] In an embodiment of the present disclosure, when the maximum duration length of a terminal device is greater than or equal to a configured nominal time window length, the terminal device may report the maximum duration length non-periodically.

[0146] Step 503: aperiodically report a maximum duration length, wherein the maximum duration length is greater than or equal to a configured nominal time window length.

[0147] In an embodiment of the present application, the terminal device may compare the configured nominal time window length with its own maximum duration length. When the configured nominal time window length is greater than its own corresponding maximum duration length, the terminal device may not report the maximum duration length and may not trigger the joint channel estimation (i.e., the joint channel estimation mechanism is not enabled). When the configured nominal time window length is less than or equal to its own maximum duration length, the terminal device may report the maximum duration length non-periodically.

[0148] Step 504: Enable the joint channel estimation mechanism and use the configured nominal time window length as the actual time window length.

[0149] In the embodiment of the present disclosure, when the terminal device reports the maximum duration length aperiodically, the joint channel estimation mechanism can be enabled, and the configured nominal time window length is used as the actual time window length. That is, when the maximum duration length is reported aperiodically, the terminal device can automatically enable the joint channel estimation without the need for the network device to send an enabling signaling.

[0150] Step 505: perform joint channel estimation processing according to the actual time window length.

[0151] In the embodiment of the present disclosure, step 505 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0152] An example is given with the nominal time window length configured for a network device, such as Figure 9 As shown, the network device can configure the nominal time window length M through RRC, MAC-CE or DCI, but there is no need to enable the joint channel estimation mechanism. After receiving the nominal time window length, the terminal device can detect the maximum duration length N corresponding to itself and determine whether M is less than or equal to N. If M≤N, the terminal device non-periodically reports the maximum duration length N. The network device receives the non-periodic report and enables the joint channel estimation mechanism. The terminal device uses M as the window length for joint channel estimation. When the joint channel estimation time length is equal to N, the joint channel estimation mechanism is automatically disabled. If M is greater than N, the terminal device does not report the maximum duration length and does not trigger the joint channel estimation.

[0153] The joint channel estimation method of the embodiment of the present disclosure determines the reporting strategy of the maximum duration length: when the maximum duration length is greater than or equal to the configured nominal time window length, the terminal device non-periodically reports the maximum duration length; non-periodically reports the maximum duration length, wherein the maximum duration length is greater than or equal to the configured nominal time window length; enables the joint channel estimation mechanism, and uses the configured nominal time window length as the actual time window length; and performs joint channel estimation processing according to the actual time window length. Thus, when the maximum duration length is greater than or equal to the configured nominal time window length, the terminal device can non-periodically report the maximum duration length, and automatically enable the joint channel estimation mechanism, and perform joint channel estimation processing according to the configured nominal time window length.

[0154] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0155] The present disclosure provides another joint channel estimation method. Figure 10A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a terminal device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0156] like Figure 10 As shown, the joint channel estimation method may include the following steps:

[0157] Step 601, determining the maximum duration length of the terminal device.

[0158] In the embodiment of the present disclosure, step 601 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0159] Step 602, determining the reporting strategy of the maximum duration length is that when the maximum duration length is less than the configured nominal time window length, the terminal device non-periodically reports the maximum duration length.

[0160] It should be noted that the above Figure 2 The explanation of the nominal time window length in the embodiment is also applicable to this embodiment and will not be repeated here.

[0161] In an embodiment of the present disclosure, when the maximum duration length of a terminal device is less than a configured nominal time window length, the terminal device may report the maximum duration length non-periodically.

[0162] Step 603: aperiodically reporting a maximum duration length, wherein the maximum duration length is less than a configured nominal time window length.

[0163] In an embodiment of the present application, the terminal device may compare the configured nominal time window length with its own maximum duration length. When the configured nominal time window length is less than or equal to its own maximum duration length, the terminal device may directly perform joint channel estimation processing according to the nominal time window length. When the configured nominal time window length is greater than its own maximum duration length, the terminal device may report the maximum duration length non-periodically.

[0164] Step 604, disabling the joint channel estimation mechanism; in response to receiving the reconfigured nominal time window length, re-enabling the joint channel estimation mechanism, and using the reconfigured nominal time window length as the actual time window length, wherein the reconfigured nominal time window length is less than or equal to the maximum duration length.

[0165] In an embodiment of the present disclosure, the terminal device may disable the joint channel estimation mechanism after non-periodically reporting the maximum duration length.

[0166] In an embodiment of the present disclosure, upon receiving the maximum duration length reported by the terminal device, the network device can reconfigure the nominal time window length based on the maximum duration length to obtain a reconfigured nominal time window length, wherein the reconfigured nominal time window length is less than or equal to the maximum duration length, and send the reconfigured nominal time window length to the terminal device. For example, the network device can reconfigure the nominal time window length through RRC, MAC-CE or DCI.

[0167] In an embodiment of the present disclosure, after receiving the reconfigured nominal time window length, the terminal device may re-enable the joint channel estimation mechanism and use the reconfigured nominal time window length as the actual time window length.

[0168] Step 605, disabling the joint channel estimation mechanism, taking the maximum duration length as the actual time window length, and re-enabling the joint channel estimation mechanism, wherein the terminal device does not receive the reconfigured nominal time window length.

[0169] In an embodiment of the present disclosure, the terminal device may disable the joint channel estimation mechanism after non-periodically reporting the maximum duration length.

[0170] In the embodiment of the present disclosure, when the terminal device does not receive the reconfigured nominal time window length sent by the network device, the terminal device may use the maximum duration length as the actual time window length and re-enable the link channel estimation mechanism.

[0171] Step 606: Perform joint channel estimation processing according to the actual time window length.

[0172] In the embodiment of the present disclosure, steps 601 to 602 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0173] An example is given with the nominal time window length configured for a network device, such as Figure 11As shown in the figure, the network device can enable the joint channel estimation mechanism and send down the nominal time window length M. When the terminal device receives M, it can detect its corresponding maximum duration length N. If N ≥ M, the terminal device directly uses M as the window length for joint channel estimation. If N < M, the terminal device performs an aperiodic report and reports the maximum duration length N to the network device. After receiving N, the network device adjusts the nominal time window length to N and sends down the reconfigured nominal time window length. When the terminal device receives the reconfigured nominal time window length, it can perform joint channel estimation processing with the reconfigured nominal time window length. When the terminal device does not receive the reconfigured nominal time window length, it can implicitly obtain the actual time window length as N and perform joint channel estimation with N as the window length.

[0174] In the joint channel estimation method according to the embodiments of the present disclosure, by determining the reporting strategy of the maximum duration length as when the maximum duration length is less than the configured nominal time window length, the terminal device aperiodically reports the maximum duration length; aperiodically reporting the maximum duration length, where the maximum duration length is less than the configured nominal time window length; disabling the joint channel estimation mechanism; in response to receiving the reconfigured nominal time window length, re-enabling the joint channel estimation mechanism and using the reconfigured nominal time window length as the actual time window length; disabling the joint channel estimation mechanism, using the maximum duration length as the actual time window length, and re-enabling the joint channel estimation mechanism, where the terminal device does not receive the reconfigured nominal time window length; performing joint channel estimation processing according to the actual time window length. Thus, when the maximum duration length is less than the configured nominal time window length, the terminal device can aperiodically report the maximum duration length and perform joint channel estimation processing according to the received reconfigured nominal time window length, or when the terminal device does not receive the reconfigured nominal time window length, it can perform joint channel estimation processing according to the maximum duration length.

[0175] It should be noted that these possible implementation manners described above can be executed separately or in combination, and the embodiments of the present disclosure do not make any limitations in this regard.

[0176] The embodiments of the present disclosure provide another joint channel estimation method. Figure 12 It is a schematic flowchart of another joint channel estimation method provided by the embodiments of the present disclosure. This joint channel estimation method can be executed by the network device. This joint channel estimation method can be executed alone, or in combination with any one of the embodiments or the possible implementation manners in the embodiments of the present disclosure, or in combination with any one of the technical solutions in the related art.

[0177] like Figure 12 As shown, the joint channel estimation method may include the following steps:

[0178] Step 701, determining the configuration information of the terminal device.

[0179] In the embodiment of the present disclosure, the configuration information of the terminal device may include at least one of the following: joint channel estimation enabling information and a nominal time window length, wherein the nominal time window length is used to determine an actual time window length.

[0180] Step 702: Send configuration information to the terminal device.

[0181] In the disclosed embodiment, the network device may send configuration information to the terminal device, so that the terminal device may determine the actual time window length based on the configuration information and its own corresponding maximum duration length, and may perform joint channel estimation processing according to the actual time window length.

[0182] It should be noted that the above Figures 1 to 11 The explanation of the joint channel estimation method performed on the terminal device side in any embodiment is also applicable to the joint channel estimation method performed on the network device side in this embodiment. The implementation principles are similar and will not be repeated here.

[0183] The joint channel estimation method of the embodiment of the present disclosure determines the configuration information of the terminal device through a network device and sends the configuration information to the terminal device. As a result, the terminal device can determine the actual time window length based on the configuration information and its own corresponding maximum duration length, so that the joint channel estimation processing can be performed according to the actual time window length.

[0184] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0185] The present disclosure provides another joint channel estimation method. Figure 13 A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a network device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0186] like Figure 13 As shown, the joint channel estimation method may include the following steps:

[0187] Step 801: Determine whether the configuration information of the terminal device includes one or more of joint channel estimation enabling information and a nominal time window length.

[0188] Among them, the reporting strategy of the terminal device for reporting the maximum duration length is not to report the maximum duration length.

[0189] Step 802: Send configuration information to the terminal device.

[0190] In a possible implementation of the embodiment of the present disclosure, when the reporting strategy of the terminal device for reporting the maximum duration length is not to report the maximum duration length, the configuration information may include joint channel estimation enabling information. At this time, the nominal time window length M may be obtained by protocol agreement or implicitly, and when the terminal device receives the joint channel estimation enabling information sent by the network device, the actual time window length M' may be determined according to the nominal time window length M and the maximum duration length N detected by itself, for example, when M≤N, M'=M, and when M>N, M'=N, so that the terminal device may perform joint channel estimation processing according to the actual time window length M'.

[0191] In another possible implementation of the embodiment of the present disclosure, when the reporting strategy of the terminal device for reporting the maximum duration length is that the maximum duration length is not reported, the configuration information may include the nominal time window length. When the network device sends the nominal time window length, the joint channel estimation may be triggered by default (i.e., the joint channel estimation mechanism may be enabled), so that the terminal device may determine the actual time window length M' according to the nominal time window length M sent by the network device and the maximum duration length N detected by itself, for example, when M≤N, M'=M, and when M>N, M'=N, so that the terminal device may perform joint channel estimation processing according to the actual time window length M'.

[0192] In another possible implementation of the embodiment of the present disclosure, when the reporting strategy of the terminal device for reporting the maximum duration length is not to report the maximum duration length, the configuration information may include joint channel estimation enable information and a nominal time window length. When the terminal device receives the joint channel estimation enable information and the nominal time window length M issued by the network device, the terminal device can determine the actual time window length M' based on the maximum duration length N and the nominal time window length M detected by itself. For example, when M≤N, M'=M, and when M>N, M'=N, so that the terminal device can perform joint channel estimation processing according to the actual time window length M'.

[0193] In the joint channel estimation method of the embodiment of the present disclosure, the configuration information of the terminal device is determined by the network device, including one or more of the joint channel estimation enabling information and the nominal time window length, wherein the reporting strategy of the terminal device for reporting the maximum duration length is not to report the maximum duration length, and the network device sends the configuration information to the terminal device. Thus, the terminal device can determine the actual time window length according to the configuration information and the maximum duration length corresponding to itself, so that the joint channel estimation process can be performed according to the actual time window length.

[0194] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0195] The present disclosure provides another joint channel estimation method. Figure 14 A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a network device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0196] like Figure 14 As shown, the joint channel estimation method may include the following steps:

[0197] Step 901, determine that the configuration information of the terminal device includes one or more of joint channel estimation enable information and a nominal time window length, wherein the nominal time window length is determined based on a maximum duration length, and the nominal time window length is less than or equal to the maximum duration length.

[0198] Among them, the reporting strategy of the terminal device for reporting the maximum duration length is to always report the maximum duration length periodically.

[0199] Step 902: Send configuration information to the terminal device.

[0200] In a possible implementation of an embodiment of the present disclosure, when the reporting strategy of the terminal device for reporting the maximum duration length is to always periodically report the maximum duration length, the configuration information may include joint channel estimation enabling information, and the nominal time window length may be included in the configuration information, or may not be included in the configuration information, and the present disclosure does not limit this. Among them, the nominal time window length is determined based on the maximum duration length, and the nominal time window length is less than or equal to the maximum duration length.

[0201] When the configuration information sent by the network device does not include the nominal time window length, the terminal device does not receive the nominal time window length, but only receives the joint channel estimation enabling information. At this time, the terminal device can use the maximum duration length as the actual time window length and perform the joint channel estimation process according to the actual time window length. When the configuration information includes both the joint channel estimation enabling information and the nominal time window length, the configuration information sent by the network device received by the terminal device includes the joint channel estimation enabling information and the nominal time window length M. The terminal device can use the nominal time window length as the actual time window length and perform the joint channel estimation process according to the actual time window length.

[0202] The joint channel estimation method of the embodiment of the present disclosure determines through a network device that configuration information of a terminal device includes one or more of joint channel estimation enabling information and a nominal time window length, wherein the nominal time window length is determined based on a maximum duration length, and the nominal time window length is less than or equal to the maximum duration length, wherein a reporting strategy for the terminal device to report the maximum duration length is to always periodically report the maximum duration length, and the network device sends configuration information to the terminal device, whereby the terminal device can determine the actual time window length based on the configuration information and its own corresponding maximum duration length, and thereby can perform joint channel estimation processing according to the actual time window length.

[0203] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0204] The present disclosure provides another joint channel estimation method. Figure 15 A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a network device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0205] like Figure 15 As shown, the joint channel estimation method may include the following steps:

[0206] Step 1001: Determine that configuration information of a terminal device at least includes a nominal time window length, wherein the nominal time window length is determined based on a maximum duration length, and the nominal time window length is less than or equal to the maximum duration length.

[0207] Among them, the reporting strategy of the terminal device for reporting the maximum duration length is that after the joint channel estimation mechanism is enabled, the terminal device periodically reports the maximum duration length.

[0208] Step 1002: Send configuration information to the terminal device.

[0209] In the embodiment of the present disclosure, the terminal device may periodically report the maximum duration length after the joint channel estimation mechanism is enabled. That is, the terminal device may periodically report the maximum duration length after the network device triggers the joint channel estimation.

[0210] In an embodiment of the present disclosure, when a network device receives a maximum duration length reported by a terminal device, the network device may configure a nominal time window length according to the maximum duration length, wherein the nominal time window length configured by the network device should be less than or equal to the maximum duration length. The network device may send configuration information to the terminal device, wherein the configuration information at least includes joint channel enabling information, and for example, may also include a nominal time window length, so that when the received configuration information includes the nominal time window length, the terminal device may use the nominal time window length as the actual time window length, and when the received configuration information does not include the nominal time window length, that is, when the nominal time window length is not received, the maximum duration length corresponding to itself may be used as the actual time window length, so that the terminal device may perform joint channel estimation processing according to the actual time window length.

[0211] In the joint channel estimation method of the embodiment of the present disclosure, the configuration information of the terminal device determined by the network device at least includes the joint channel estimation mechanism enabling information, and may also include the nominal time window length, wherein the nominal time window length is determined based on the maximum duration length, and the nominal time window length is less than or equal to the maximum duration length, wherein the reporting strategy of the terminal device reporting the maximum duration length is that after the joint channel estimation mechanism is enabled, the terminal device periodically reports the maximum duration length, and the network device sends the configuration information to the terminal device. Thus, the terminal device can determine the actual time window length according to the configuration information and the maximum duration length corresponding to itself, so that the joint channel estimation process can be performed according to the actual time window length.

[0212] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0213] The present disclosure provides another joint channel estimation method. Figure 16A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a network device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0214] like Figure 16 As shown, the joint channel estimation method may include the following steps:

[0215] Step 1101: Determine whether the configuration information of the terminal device includes a nominal time window length, which is used to determine an actual time window length.

[0216] Among them, the reporting strategy of the terminal device for reporting the maximum duration length is to report the maximum duration length non-periodically based on the maximum duration length being greater than or equal to the nominal time window length.

[0217] Step 1102: Send configuration information to the terminal device.

[0218] In an embodiment of the present disclosure, the configuration information sent by the network device to the terminal device may include a nominal time window length. After receiving the configuration information, if the terminal device determines that its corresponding maximum duration length is greater than or equal to the nominal time window length in the configuration information, the terminal device may non-periodically report the maximum duration length, enable the joint channel estimation mechanism, and use the nominal time window length configured by the network device as the actual time window length, and perform joint channel estimation processing according to the actual time window length.

[0219] In the joint channel estimation method of the embodiment of the present disclosure, the configuration information of the terminal device is determined by the network device, including the nominal time window length, which is used to determine the actual time window length; wherein the reporting strategy of the terminal device reporting the maximum duration length is, based on the maximum duration length being greater than or equal to the nominal time window length, the maximum duration length is reported non-periodically, and the network device sends the configuration information to the terminal device. Thus, the terminal device can determine the actual time window length according to the configuration information and the maximum duration length corresponding to itself, so that the joint channel estimation process can be performed according to the actual time window length.

[0220] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0221] The present disclosure provides another joint channel estimation method. Figure 17A flowchart of another joint channel estimation method provided by an embodiment of the present disclosure. The joint channel estimation method can be executed by a network device. The joint channel estimation method can be executed alone, or can be executed together with any embodiment of the present disclosure or a possible implementation method in an embodiment, or can be executed together with any technical solution in the related art.

[0222] like Figure 17 As shown, the joint channel estimation method may include the following steps:

[0223] Step 1201, receive disabling joint channel estimation information, and re-determine configuration information based on the maximum duration length reported by the terminal device, wherein the configuration information at least includes: a reconfigured nominal time window length and re-enabling joint channel estimation information, wherein the reconfigured nominal time window length is less than or equal to the maximum duration length.

[0224] Among them, the reporting strategy of the terminal device for reporting the maximum duration length is to report the maximum duration length non-periodically based on the maximum duration length being less than the configured nominal time window length.

[0225] Step 1202: Send configuration information to the terminal device.

[0226] In an embodiment of the present disclosure, the terminal device may compare the configured nominal time window length with its own maximum duration length. When the configured nominal time window length is less than or equal to its own maximum duration length, the terminal device may directly perform joint channel estimation processing according to the nominal time window length. When the configured nominal time window length is greater than its own maximum duration length, the terminal device may non-periodically report the maximum duration length. The above-mentioned configured nominal time window length may be configured by the network device, or may be agreed upon by the protocol or obtained implicitly, and the present disclosure does not limit this.

[0227] In an embodiment of the present disclosure, after the terminal device reports the maximum duration length non-periodically, the joint channel estimation mechanism may be disabled. When the network device receives the maximum duration length reported by the terminal device, the nominal time window length may be reconfigured according to the maximum duration length to obtain the reconfigured nominal time window length, wherein the reconfigured nominal time window length should be less than or equal to the maximum duration length. The network device may send configuration information to the terminal device, wherein the configuration information at least includes the reconfigured nominal time window length and the re-enabling joint channel estimation information. Accordingly, after receiving the configuration information, the terminal device may re-enable the joint channel estimation mechanism, and use the reconfigured nominal time window length in the configuration information as the actual time window length, so that the terminal device may perform the joint channel estimation process according to the actual time window length. In the case where the configuration information sent by the network device is not received, the terminal device may use the maximum duration length as the actual time window length, and re-enable the joint channel estimation mechanism, and perform the joint channel estimation process according to the actual time window length.

[0228] The joint channel estimation method of the embodiment of the present disclosure is that the network device responds to receiving the information of disabling the joint channel estimation, and re-determines the configuration information according to the maximum duration length reported by the terminal device, wherein the configuration information at least includes: the reconfigured nominal time window length and the re-enabling joint channel estimation information, wherein the reconfigured nominal time window length is less than or equal to the maximum duration length, wherein the reporting strategy of the maximum duration length reported by the terminal device is based on the maximum duration length being less than the configured nominal time window length, the maximum duration length is non-periodically reported, and the network device sends the reconfiguration information to the terminal device. Thus, the terminal device can determine the actual time window length according to the configuration information re-determined by the network device and the maximum duration length corresponding to itself, so that the joint channel estimation processing can be performed according to the actual time window length.

[0229] It should be noted that the above-mentioned possible implementation methods can be executed separately or in combination, and the embodiments of the present disclosure are not limited to this.

[0230] With the above Figures 1 to 11 Corresponding to the joint channel estimation method provided in the embodiment, the present disclosure also provides a joint channel estimation device. Figures 1 to 11 The joint channel estimation method provided in the embodiment corresponds to the embodiment, so the implementation of the joint channel estimation method is also applicable to the joint channel estimation device provided in the embodiment of the present disclosure, and will not be described in detail in the embodiment of the present disclosure.
