Description

Technical Field

[0001] The present disclosure relates to a wireless communication system, and particularly to an indication method, an indication device, and a storage medium.

Background Art

[0002] In a new generation version of communication technology, joint channel estimation has been proposed to enhance the coverage of the Physical Uplink Shared Channel (PUSCH). The network-side device is exemplified by a base station (for example, gNB). For joint channel estimation, both the base station (for example, gNB) and the terminal (User Equipment, UE) require a time window, and the UE needs to maintain power consistency and phase continuity within the time window in order to cooperate with the base station (for example, gNB) to perform joint channel estimation in the time window.

[0003] In related technologies, repeated transmission supporting Message 3 (Message3, Msg3) and joint channel estimation between slots have been proposed. However, in practice, it has been found that the terminal cannot maintain power consistency and phase continuity while the base station (for example, gNB) performs joint channel estimation.

[0078] Herein, exemplary embodiments are described, and these examples are shown in the drawings. Where the drawings relate to the following, unless otherwise noted, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure, which are described in detail in the appended claims.

[0079] Figure 1 is a diagram of a communication system architecture of a network device and a terminal as shown in an exemplary embodiment. The communication method provided in this disclosure can be applied to the communication system architecture diagram shown in Figure 1. As shown in Figure 1, the network-side device can transmit signaling based on the architecture shown in Figure 1.

[0080] The communication system between network devices and terminals shown in Figure 1 is merely illustrative, and the wireless communication system may further include other network devices, such as core network devices, wireless relay devices, and wireless backhaul devices not shown in Figure 1. The embodiments of this disclosure do not limit the number of network devices and terminals included in the wireless communication system.

[0081] The wireless communication system in the embodiments of this disclosure is a network that provides wireless communication functionality. The wireless communication system can utilize different communication technologies, such as code division multiple access (CDMA), broadband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and carrier-sense multiple access with collision avoidance. Based on factors such as network capacity, speed, and latency, networks can be categorized into future-evolving networks such as 2G (generation) networks, 3G networks, 4G networks, or 5G networks, with 5G networks also being called New Radio (NR). For ease of explanation, this disclosure may also refer to wireless communication networks simply as "networks."

[0082] Furthermore, the network devices relating to this disclosure may also be called wireless access network devices. Such wireless access network devices may be base stations, evolved node B (base stations), home base stations, access points (APs) in wireless fidelity (WIFI) systems, wireless relay nodes, wireless backhaul nodes, transmission points (TPs) or transmission and reception points (TRPs), or gNBs in NR systems, or components or parts of devices that constitute a base station. In the case of a vehicle internet (V2X) communication system, the network device may further be an in-vehicle device. It should be understood that the embodiments of this disclosure are not limited to the specific technologies and specific device forms used for the network devices.

[0083] Furthermore, the terminals relating to this disclosure are also called terminal devices, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc., and are devices that provide voice and / or data communication to a user. For example, a terminal may be a handheld device with a wired connection function, an in-vehicle device, etc. Currently, some examples of terminals include mobile phones, pocket personal computers (PPCs), personal information terminals, personal digital assistants (PDAs), notebook computers, tablets, wearable devices, or in-vehicle devices. Also, in the case of a vehicle internet (V2X) communication system, the terminal device may be an in-vehicle device. The embodiments of this disclosure do not limit the specific technology used by the terminal or the specific form of the device.

[0084] In a new generation of communication technology, joint channel estimation was proposed to enhance the coverage of the physical uplink shared channel PUSCH. Simultaneously, it was proposed to enhance Msg3 coverage using PUSCH type A repeats. After introducing Msg3 type A repeats, inter-slot channel estimation becomes possible.

[0085] During the repeated reception period of Msg3, under certain conditions, the network-side device can perform channel estimation between slots. Therefore, for joint channel estimation, if we consider the network-side device as a gNB, both the gNB and the UE require one time window, and the UE needs to maintain power consistency and phase continuity during that time window so that it performs joint channel estimation in accordance with the gNB.

[0086] Here, the terminal needs to maintain power consistency and phase continuity during the process in which the gNB performs joint channel estimation, and in order to maintain power consistency and phase continuity, the following related conditions must be met. (1) The modulation level does not change. (2) The RB assignments related to length and frequency position shall not change, and frequency hopping within and between slots shall not be enabled during the iterative process. (3) The transmission power level does not change. (4) The terminal's uplink beam will not be switched within the radio frequency range (FR) 2.

[0087] Therefore, if gNB needs to perform joint channel estimation, it is necessary to instruct the terminal to maintain that the above-mentioned relevant conditions do not change within the time window in which the joint channel estimation is performed. Under certain conditions, the channel estimation results for inter-slot channel estimation will be more accurate, which is advantageous for coverage enhancement / coverage recovery.

[0088] In related technologies, it is not defined how the network-side device instructs the terminal whether or not to perform joint channel estimation, nor is there a defined time window for performing joint channel estimation.

[0089] This disclosure proposes a method for instructing a terminal whether or not to perform joint channel estimation when repeating Msg3, and the time window required to perform joint channel estimation.

[0090] Figure 2 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 2, the instruction method is applied to a terminal and includes the following step S11.

[0091] In step S11, the first message is determined.

[0092] In embodiments of this disclosure, a first message is used by a terminal to determine configuration parameters for a network-side device to perform joint channel estimation, where the configuration parameters may include instructional information that instructs the network-side device to enable joint channel estimation and / or fixed parameter values ​​or parameter sets that determine the length of the time window for joint channel estimation. The parameter set or fixed parameter values ​​for determining the joint channel estimation time window can be instructed by a network-side device (e.g., a base station) or determined based on a communication protocol. The instructions from the network side include multiple instruction methods. See the following embodiments.

[0093] In some embodiments of this disclosure, a first message is used to instruct configuration information for joint channel estimation, where the configuration information includes instruction information. This instruction information is used to instruct a terminal that a network-side device enables joint channel estimation. Such embodiments may be implemented independently or in conjunction with any one of the other embodiments of this disclosure.

[0094] In some embodiments of this disclosure, a terminal receives a first message and decides that the network-side device enables joint channel estimation.

[0095] In embodiments of this disclosure, configuration information can be determined based on explicit signaling, such as Remaining Minimum System Information (RMSI). A terminal receives an RSMI, determines the first message carried by the RSMI, and further determines the configuration information contained in the first message. Here, the RSMI can be scheduled based on Downlink Control Information (DCI).

[0096] In embodiments of this disclosure, configuration information can be determined for uplink grant information (UL grant) within a Random Access Response (RAR) based on explicit signaling. The terminal determines whether the network-side device enables joint channel estimation based on the first message carried by the RAR UL grant.

[0097] In embodiments of the present disclosure, based on explicit signaling, a scrambled sequence of a Cyclic Redundancy Check (CRC) can determine configuration information for a DCI scrambled for a Random Access Radio Network Temporary Identifier (RA-RNTI). The terminal uses the scrambled sequence of the CRC to determine whether the network-side device enables joint channel estimation for the RA-RNTI DCI.

[0098] In embodiments of the present disclosure, the CRC may also determine configuration information for DCI scrambled for the Temporary Access Cell Radio Network Temporary Identifier (TC-RNTI) based on explicit signaling. In other words, the terminal determines that the network-side device enables joint channel estimation based on the DCI scrambled for the TC-RNTI by the CRC.

[0099] In embodiments of this disclosure, a network-side device can instruct a terminal whether or not to enable joint channel estimation based on an implicit instruction scheme. For example, if the terminal is instructed to repeatedly send Msg3, the network-side device decides to enable joint channel estimation.

[0100] In the embodiments of this disclosure, the embodiment in which the network-side device enables joint channel estimation can be applied to joint channel estimation of a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH).

[0101] Here, an explicit signaling instruction can be used to instruct the system to enable joint channel estimation. Explicit signaling may include radio resource control (RRC), system information block (SIB), DCI, MAC layer control element (MAC CE), etc.

[0102] In some embodiments of the present disclosure, a first message is used to determine time window length setting information for joint channel estimation, where the setting information includes a set of parameters or fixed parameter values ​​for determining the length of the time window for joint channel estimation. Such embodiments may be implemented independently or in conjunction with any one of the other embodiments of the present disclosure.

[0103] In one embodiment of the present disclosure, a terminal can determine a first message based on a predefined rule / communication protocol and determine a setting parameter for the length of the time window for joint channel estimation within the first message. In one embodiment, a parameter set for determining the time window length for joint channel estimation is determined based on a predefined rule / communication protocol, and this parameter set may be set for a cell. That is, a terminal in the cell uses a parameter set of a predefined rule / communication protocol. At a network-side device (e.g., a base station), a terminal determines one parameter in the determined parameter set based on a parameter set index indicated by the base station, and determines the time window length for joint channel estimation based on that parameter. In one embodiment, a fixed parameter value can be determined based on a predefined rule / communication protocol, and the length of the time window for joint channel estimation is determined using this fixed parameter value.

[0104] In another embodiment of the present disclosure, the terminal may determine a first message based on explicit instruction signaling and further determine a set of parameters or fixed parameter values ​​for determining the time window length of joint channel estimation, which are included in the configuration information.

[0105] In some embodiments of this disclosure, the explicit instruction signaling may be RSMI. A terminal can receive an RMSI and determine a first message carried by the RSMI. In one embodiment, based on the first message carried by the RSMI, a configuration parameter for determining the length of the joint channel estimation time window is determined. This configuration parameter includes a parameter set for the length of the joint channel estimation time window. The terminal further determines one parameter from the parameter set based on a parameter set index indicated by the network-side device, and determines the length of the joint channel estimation time window based on that parameter. In one embodiment, a fixed parameter value for indicating the length of the joint channel estimation time window is determined based on the first message carried by the RSMI. Herein, the embodiment may be configured to deal with all terminals in a cell. That is, a terminal in the cell receives an RMSI, determines a first message carried by the RSMI, and determines its joint channel estimation configuration parameter.

[0106] In some embodiments of this disclosure, the explicit scheme may be DCI scrambled by the CRC for RA-RNTI. The terminal can determine a setting parameter for the length of the joint channel estimation time window based on the DCI scrambled by the CRC for RA-RNTI. In one embodiment, the terminal determines, based on the DCI scrambled by the CRC for RA-RNTI (e.g., DCI format 1_0), that the setting parameter is an index of a parameter set for determining the length of the joint channel estimation time window, and further determines the length of the joint channel estimation time window based on that parameter set index. Here, the parameter set may be a list, configured by RMSI and / or configured in a protocol, and its index further indicated by DCI scrambled by the CRC for RA-RNTI or RAR of the uplink grant, and the terminal further determines a parameter in the parameter set by a network-side device-indicative parameter set index, and determines the length of the joint channel estimation time window based on that parameter. Here, the list of parameters may be a new list or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). In one embodiment, the CRC can specify a fixed parameter value by the DCI scrambled for RA-RNTI, and the terminal determines the length of the time window for joint channel estimation based on this fixed parameter value. Here, the embodiment may be a configuration for a set of terminals.

[0107] In some embodiments of this disclosure, the explicit scheme may be DCI scrambled by the CRC for TC-RNTI (e.g., DCI format 0_0). Based on the DCI scrambled by the CRC for TC-RNTI, the terminal determines a setting parameter for the length of the joint channel estimation time window. In one embodiment, the setting parameter determined based on the DCI scrambled by the CRC for TC-RNTI is an index of a parameter set for the length of the joint channel estimation time window, and the terminal further determines the length of the joint channel estimation time window based on that parameter set index. The parameter set may be a list, which is set by RMSI and / or in a protocol, and whose index is further indicated by the DCI scrambled by the CRC for TC-RNTI, and the terminal further determines a parameter in the parameter set based on the parameter set index indicated by the network-side device, and determines the length of the joint channel estimation time window based on that parameter. Exemplary, a parameter set includes multiple parameters, e.g., [2, 4, 8], and the specified parameter set index determines the time window length parameter for joint channel estimation within that parameter set. Here, the list of parameter sets may be a new list or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). In one embodiment, a fixed parameter value may be specified based on the DCI scrambled by the CRC for TC-RNTI. The terminal determines the time window length for joint channel estimation based on this fixed parameter value. This embodiment may target a specific terminal.

[0108] In some embodiments of this disclosure, the explicit method may be a RAR UL grant. Based on the RAR UL grant, the terminal determines a setting parameter for the length of the joint channel estimation time window. In one embodiment, the setting parameter determined based on the RAR UL grant is an index in a parameter set for the length of the joint channel estimation time window, and the terminal further determines the length of the joint channel estimation time window based on that parameter set index. The parameter set for the length of the joint channel estimation time window may be a single list, which is set by RMSI and / or in a protocol, and whose index is further indicated by the RAR UL grant, and the terminal further determines a parameter in the parameter set by the parameter set index indicated by the network-side device, and determines the length of the joint channel estimation time window based on that parameter. Exemplaryly, the parameter set includes multiple parameters, e.g., [2, 4, 8], and the indicated parameter set index determines the parameter for the length of the joint channel estimation time window in that parameter set. Here, the list of parameters may be a new list or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). In one embodiment, a fixed parameter value can be determined based on the RAR UL grant. The terminal determines the length of the time window for joint channel estimation based on this fixed parameter value. This embodiment may target a specific terminal.

[0109] In some other embodiments of this disclosure, the parameters for the time window length of joint channel estimation can be implicitly specified. For example, the parameters for the time window length of joint channel estimation can be implicitly determined based on the number of repeated transmissions. Exemplarily, the time window length of joint channel estimation is the number of slots corresponding to the number of repeated transmissions / N, where N is a positive integer, for example, N = 2. Of course, this is merely illustrative and not a specific limitation of this disclosure.

[0110] In some embodiments of this disclosure, a first message is used to instruct configuration information for joint channel estimation, which includes a set of parameters or fixed parameter values ​​to instruct the terminal to enable joint channel estimation and the length of the time window for joint channel estimation. Such embodiments may be implemented independently or in conjunction with any one of the other embodiments of this disclosure.

[0111] In one embodiment of the present disclosure, a terminal determines a first message based on an RMSI instruction provided by a network-side device, wherein the first message is a fixed value, and the terminal determines, based on the fixed value, whether the network side enables or disables joint channel estimation, and simultaneously, the fixed value can further determine the length of the joint channel estimation window. Exemplarily, if the fixed value is carried in the RMSI, the terminal determines that the network side has enabled joint channel estimation, and further determines the length of the joint channel estimation time window based on the fixed value; if the fixed value is not carried in the RMSI, the terminal determines that the network side has not enabled joint channel estimation. Exemplarily, if the fixed value is carried in the RMSI and the fixed value is 0 or 1, the terminal determines that the network side has disabled joint channel estimation; if the fixed value is carried in the RMSI and the value is greater than 1, the terminal determines that the network side has enabled joint channel estimation, and further determines the length of the joint channel estimation time window based on the fixed value.

[0112] In another embodiment of the present disclosure, configuration information instructing joint channel estimation can be determined based on DCI scrambled for RA-RNTI (e.g., DCI format 1_0) by the CRC. In one embodiment, the configuration information includes a fixed value for enabling or disabling joint channel estimation. If the fixed value is 0 or 1, it is determined to disable joint channel estimation. If the fixed value is 1 or any other value other than 0, it is determined to enable joint channel estimation and to determine the length of the joint channel estimation time window based on the fixed value. In another embodiment, the configuration information includes a parameter set for the length of the joint channel estimation time window. This parameter set is configured by RMSI or defined by the protocol, and its parameter set index is further indicated by DCI scrambled for RA-RNTI by the CRC. Based on the parameter set index indicated by the network-side device, the terminal determines one parameter in the parameter set and, based on that parameter, determines whether to enable joint channel estimation and the length of the joint channel estimation time window. The parameter set may be a single table, a new list, or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). Exemplarily, assuming the parameters included in the parameter set are [0, 2, 4, 8], a parameter of 0 means that joint channel estimation is disabled, and if the parameter is any one of the remaining parameters, it is decided to enable joint channel estimation and to determine that parameter as the length of the time window for joint channel estimation. Of course, parameter 0 may also be parameter 1, and if parameter 1 is indicated, it is decided not to enable joint channel estimation, and this is not specifically limited. The embodiment may be a setting for a set of terminals.

[0113] In further embodiments of the present disclosure, configuration information instructing joint channel estimation can be determined based on DCI (e.g., DCI format 0_0) scrambled by the CRC for TC-RNTI. In one embodiment, the configuration information includes a fixed value for enabling or disabling joint channel estimation. If the fixed value is 0 or 1, it is determined to disable joint channel estimation. If the fixed value is 1 or any other value other than 0, it is determined to enable joint channel estimation and to determine the fixed value as the length of the joint channel estimation time window. In another embodiment, the configuration information includes a parameter set for the length of the joint channel estimation time window. This parameter set is configured by RMSI or defined by the protocol, and its parameter set index is further indicated by DCI scrambled by the CRC for RA-RNTI. Based on the parameter set index indicated by the network-side device, the terminal determines one parameter from the parameter set, and based on that parameter, determines whether to enable joint channel estimation and the length of the joint channel estimation time window. The parameter set may be a single table, a new list, or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). For example, the parameters in the parameter set are [0, 2, 4, 8], where a parameter of 0 indicates that joint channel estimation is prohibited, and if the parameter is any one of the remaining parameters, it is decided to enable joint channel estimation and determine the length of the time window for joint channel estimation based on that parameter. Of course, parameter 0 may also be parameter 1, and indicating that the parameter is 1 indicates that joint channel estimation is not enabled, and this is not specifically limited.

[0114] In further embodiments of the present disclosure, configuration information instructing joint channel estimation can be determined based on DCI (e.g., DCI format 0_0) scrambled by the CRC for TC-RNTI. In one embodiment, the configuration information includes a fixed value for enabling or disabling joint channel estimation. If the fixed value is 0 or 1, it is determined to disable joint channel estimation. If the fixed value is 1 or any other value other than 0, it is determined to enable joint channel estimation and to determine the fixed value as the length of the joint channel estimation time window. In another embodiment, the configuration information includes a parameter set for the length of the joint channel estimation time window. This parameter set is configured by RMSI or defined by the protocol, and its parameter set index is further indicated by DCI scrambled by the CRC for RA-RNTI. Based on the parameter set index indicated by the network-side device, the terminal determines one parameter from the parameter set, and based on that parameter, determines whether to enable joint channel estimation and the length of the joint channel estimation time window. The parameter set may be a single table, a new list, or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). For example, the parameters in the parameter set are [0, 2, 4, 8], where a parameter of 0 indicates that joint channel estimation is prohibited, and if the parameter is any one of the remaining parameters, it is decided to enable joint channel estimation and determine the length of the time window for joint channel estimation based on that parameter. Of course, parameter 0 may also be parameter 1, and indicating that the parameter is 1 indicates that joint channel estimation is not enabled, and this is not specifically limited.

[0115] In embodiments of this disclosure, as described above, the network-side device determines a parameter set or fixed parameter value for the length of the time window for joint channel estimation. Here, each parameter or fixed parameter value in the parameter set can be determined based on the number of repeated transmissions of terminal Msg3. For example, each parameter or fixed parameter value in the parameter set may be determined to be a common factor for all selectable number of repeated transmissions. Exemplarily, if the selectable number of repeated transmissions is 4 or 8, the parameters in the parameter set may be determined to be 2 or 4. Alternatively, the set fixed parameter value may be determined to be 4. Of course, this is merely an example and not a specific limitation to this disclosure.

[0116] The instruction method provided by the embodiments of this disclosure can instruct a terminal to enable network-side device joint channel estimation and to specify the time window for performing joint channel estimation. This solves the problem of not being able to instruct a terminal to enable joint channel estimation and to specify the time window for performing joint channel estimation.

[0117] In the embodiments of this disclosure, the terminal decides to enable joint channel estimation based on the received configuration information and obtains parameters used for the length of the time window of the joint channel estimation. Based on the obtained parameters, joint channel estimation is performed, and the following embodiments can be used.

[0118] Figure 3 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 3, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure, and includes the following steps S21 to S22.

[0119] In step S21, the first parameter is determined in the parameter set based on the set parameters, or a fixed parameter value is determined as the first parameter.

[0120] In step S22, the length of the time window for performing joint channel estimation is determined based on the first parameter.

[0121] In the embodiments of this disclosure, a first parameter is determined in the parameter set, or a fixed parameter value is determined as the first parameter, as in the determination of the setting parameters described above. Based on the first parameter, the length of the time window in which joint channel estimation is performed is determined. For the sake of clarity, this disclosure refers to the parameter indicated in the parameter set based on the setting information as the first parameter.

[0122] Figure 4 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 4, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S31.

[0123] In step S31, the first parameter is determined as the length of the time window in which joint channel estimation is performed.

[0124] In an exemplary embodiment of this disclosure, a configuration parameter obtains a set of parameters for determining the length of the time window for joint channel estimation, and a parameter within the parameter set indicated by the base station is determined as the length of the time window for performing joint channel estimation. Alternatively, a configuration parameter obtains a fixed parameter value for determining the time window for joint channel estimation, and this parameter value is determined as the length of the time window for performing joint channel estimation. Exemplarily, the set of parameters for determining the length of the time window for joint channel estimation includes, for example, a set of parameters such as 2, 4, and 8, respectively. If the parameter indicating the length of the time window for joint channel estimation is 4, then the duration for performing joint channel estimation is determined to be 4. Here, the duration may be a slot, i.e., the length of the time window for joint channel estimation is four consecutive slots. In other words, the network-side device repeatedly performs joint channel estimation once for every four slots. Here, the duration may be other scheduling time units, and is not specifically limited here.

[0125] In embodiments of this disclosure, the first parameter is determined as a time window for performing joint channel estimation, and if the transmission time for the number of iterations is shorter than the length of the joint channel estimation time window, joint channel estimation can be performed based on a different policy. See the following embodiments.

[0126] Figure 5 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 5, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S41.

[0127] In step S41, the transmission time corresponding to the number of repeated transmissions is determined, and if the transmission time is less than the first parameter, joint channel estimation is performed based on the first policy.

[0128] In the embodiments of this disclosure, the terminal determines a transmission time corresponding to the number of repetitions. For example, the repetitive message is Msg3, and the number of repetitions of Msg3 is 2. If the determined first parameter is 4, the transmission time corresponding to the number of repetitions is less than the first parameter, and it is decided to perform joint channel estimation based on the first policy.

[0129] In some embodiments of this disclosure, performing joint channel estimation based on the first policy includes canceling joint channel estimation; that is, canceling enabling joint channel estimation if the transmission time is less than the first parameter.

[0130] In some embodiments of this disclosure, performing joint channel estimation based on the first policy includes redetermining the length of the time window for joint channel estimation based on a predefined rule, and then performing joint channel estimation based on the redetermined length of the time window.

[0131] For example, the length of the time window for joint channel estimation can be determined based on predefined rules, where the transmission time for the number of repeated transmissions or half of the transmission time is the length of the actual time window for joint channel estimation. The transmission time for the number of repeated transmissions can be determined as the length of the time window for performing joint channel estimation. Furthermore, a fixed value indicated by the communication protocol can be determined as the length of the time window for performing joint channel estimation. Furthermore, a value specified by the network-side device based on configuration parameters can be determined as the length of the time window for performing joint channel estimation. Furthermore, a value that is close to a specified value and smaller than the transmission time corresponding to the number of repeated transmissions can be determined as the time window for performing joint channel estimation.

[0132] In some embodiments of this disclosure, performing joint channel estimation based on the first policy involves redetermining the length of the joint channel estimation time window based on the transmission time of the number of repetitions. Exemplarily, the duration of the joint channel estimation is specified as a common factor of all selectable repetitions. Based on this common factor, the time window in which the joint channel estimation is performed is determined.

[0133] Figure 6 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 6, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S51.

[0134] In step S51, the transmission time corresponding to the number of blind repeated transmissions is determined, and if there is a remainder in the quotient value between the transmission time and the first parameter, joint channel estimation is performed based on the second policy.

[0135] In embodiments of this disclosure, the transmission time corresponding to the number of blind repeated transmissions is determined, and if the remaining transmission time after performing joint channel estimation based on the transmission time is shorter than the length of the time window for the next joint channel estimation, it is decided to perform joint channel estimation using the second policy.

[0136] In some embodiments of this disclosure, performing joint channel estimation based on the second policy includes canceling joint channel estimation. That is, if the remaining transmission time after performing joint channel estimation with respect to transmission time is shorter than the length of the time window for performing the next joint channel estimation, it is decided to cancel enabling joint channel estimation.

[0137] In some embodiments of this disclosure, performing joint channel estimation based on the second policy includes canceling joint channel estimations for slots within the remainder of the quotient between the transmission time and the first parameter. In other words, it cancels joint channel estimations where the transmission time after the joint channel estimation is shorter than the length of the time window for the next joint channel estimation.

[0138] In some embodiments of this disclosure, performing joint channel estimation based on a second policy includes redetermining the length of the joint channel estimation time window based on predefined rules and performing joint channel estimation based on the redetermined joint channel estimation time window length. Furthermore, the terminal determines the length of the time window for all overlapping joint channel estimations based on predefined rules. The terminal may subdivide the length of the joint channel estimation time window based on the transmission time corresponding to the number of repeated transmissions.

[0139] In some embodiments of this disclosure, performing joint channel estimation based on a second policy includes determining, based on a predefined rule, that the time corresponding to the remainder of the quotient between the transmission time and the first parameter is the length of the time window for joint channel estimation. The terminal performs joint channel estimation based on the length of the redetermined time window. The terminal determines, based on a predefined rule, the remainder of the quotient between the transmission time and the first duration, i.e., the remaining transmission time after performing joint channel estimation. For the remaining transmission time, it can be determined that the duration for performing joint channel estimation coincides with the remaining transmission time. For example, if the repeated transmission has 14 slots and the first parameter has 4 slots, the remainder is 2, and the length of the time window for performing the last joint channel estimation is determined to be 2.

[0140] In some embodiments of this disclosure, performing joint channel estimation based on the second policy further includes redetermining the length of the time window for performing joint channel estimation based on the number of repeated transmissions and the length of the time window for joint channel estimation. Exemplaryly, a division is performed based on each selectable number of repeated transmissions to determine the length of the time window for selectable joint channel estimation.

[0141] Figure 7 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 7, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S61.

[0142] In step S61, the transmission time corresponding to the number of repeated transmissions is determined, and the transmission time calculation is performed based on a predefined calculation rule to obtain a second parameter, which is then determined as the length of the time window in which joint channel estimation is performed.

[0143] In one exemplary embodiment of this disclosure, the transmission time corresponding to repeated transmissions is determined in the configuration parameters. Furthermore, the transmission time is calculated based on a predefined calculation rule, and the resulting calculated value (relative value) is determined as a second parameter. The second parameter is determined as the length of the time window in which joint channel estimation is performed.

[0144] Figure 8 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 8, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S71.

[0145] In step S71, the transmission time corresponding to the number of repeated transmissions is determined, and the quotient of the transmission time and a predefined parameter value is determined as the second parameter.

[0146] In embodiments of this disclosure, a quotient calculation can be performed on the transmission time based on a predefined parameter value. For example, the transmission time corresponding to the number of repeated transmissions determined based on a pre-set parameter value of 4 is 12, and this time may be in slots. The duration for performing joint channel estimation is determined to be 3. In other words, the network-side device can repeatedly perform joint channel estimation once for every three slots.

[0147] In some embodiments of this disclosure, when the relative number of repeated transmissions is determined as the duration for performing joint channel estimation, there are cases where the second parameter is smaller than the first value, and where there is a remainder after performing a quotient operation on the second parameter.

[0148] Figure 9 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 9, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S81.

[0149] In step S81, in response to the second parameter being smaller than the first value, joint channel estimation is performed based on the third policy.

[0150] In embodiments of this disclosure, joint channel estimation is performed based on a second policy when the second parameter is less than the first numerical value, where the first numerical value may be 1. For example, the transmission time corresponding to repeated transmissions is 2, and the duration for performing joint channel estimation, as instructed by the network-side device, is 4, where the time may be in slots. If the second duration is 2 / 4, the network-side device cannot perform joint channel estimation.

[0151] In some embodiments of this disclosure, performing joint channel estimation based on a third policy includes canceling joint channel estimation; that is, deciding to cancel enabling joint channel estimation when the second parameter is less than the first value.

[0152] In some embodiments of this disclosure, performing joint channel estimation based on a third policy includes being able to re-determine the second parameter based on a predefined rule. For example, in iterations of Msg3, the duration for performing joint channel estimation is re-determined. For instance, this may be half the duration granularity, or a fixed value may be determined to be smaller than the transmission time of the iteration transmission.

[0153] In some embodiments of this disclosure, performing joint channel estimation based on a third policy involves redetermining the length of the time window for performing joint channel estimation based on the transmission time of repeated transmissions.

[0154] Figure 10 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 10, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S91.

[0155] In step S91, in response to the existence of a remainder in the second parameter, joint channel estimation is performed based on the fourth policy.

[0156] In the embodiments of this disclosure, a fourth policy can be executed when there is a remainder after performing a quotient operation on the second parameter. For example, if the transmission time for repeated transmissions is 14 and the relative value of the repetitions is 4, there may be a remainder in 14 / 4. The time may also be in slots.

[0157] In some embodiments of this disclosure, performing joint channel estimation based on the fourth policy includes determining a lower limit on the time granularity for performing joint channel estimation. Exemplaryly, the duration can be chosen to be three slots. In other words, when the network-side device actually performs joint channel estimation, it may perform joint channel estimation five times, with the first four joint channel estimations having a duration of three slots and the last joint channel estimation having a duration of two slots. Alternatively, the network-side device may perform joint channel estimation four times, with the last two remaining slots not being used for joint channel estimation.

[0158] In some embodiments of this disclosure, performing joint channel estimation based on the fourth policy involves determining a quotient value that is an integer multiple of the second duration; that is, determining the integer value of the quotient operation as the length of the time window in which the joint channel estimation is performed.

[0159] In some embodiments of this disclosure, performing joint channel estimation based on the fourth policy includes redetermining the second duration based on a predefined rule. In other words, a fixed value is redetermined based on a predefined rule, and a relative value divisible by the transmission time of repeated transmissions is determined relative to that fixed value as the length of the time window for performing joint channel estimation. Here, the relative value may be determined by the protocol or indicated by the network side, and the relative value may be less than or greater than the fixed value.

[0160] In some embodiments of this disclosure, performing joint channel estimation based on policy 4 includes redetermining the length of the time window in which joint channel estimation is performed based on the transmission time of repeated transmissions and the duration granularity of the joint channel estimation.

[0161] In some embodiments of this disclosure, performing joint channel estimation based on the first policy includes canceling joint channel estimation, that is, deciding to cancel enabling joint channel estimation in the case where there is a remainder in the quotient operation.

[0162] Figure 11 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 11, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S101.

[0163] In step S101, supplementary information is reported.

[0164] In embodiments of this disclosure, auxiliary information is used by the network-side device to determine configuration parameters for performing joint channel estimation. Here, the auxiliary information may be speed information, etc. Different speed information represents different channel state change information. Based on the channel state change information reported by the terminal, the network side can be assisted in determining whether or not to enable joint channel estimation and the length of the time window for performing joint channel estimation.

[0165] Figure 12 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 12, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S111.

[0166] In step S111, auxiliary information is reported based on random access message 1.

[0167] In the embodiments of this disclosure, different speed information can be determined based on different Physical Random Access Channel (PRACH) resource groups within Msg1. PRACH resources may include time-frequency resources, frequency-domain resources, code-domain resources, etc. A terminal can inform itself of the current channel status by sending a preamble based on the group corresponding to its speed.

[0168] Figure 13 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 13, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S121.

[0169] In step S121, auxiliary information is reported based on the Demodulation Reference Signal (DMRS).

[0170] In embodiments of this disclosure, the channel status of a terminal is communicated to a network-side device by reporting different speed information based on different DMRS. DMRS may be a time-domain location, a frequency-domain location, a code-domain location, etc. Note that speed information is reported using DMRS, and joint channel estimation is not performed during the initial transmission process. Alternatively, the initial transmission of Msg3 uses the joint channel estimation setting parameters instructed by the base station. In embodiments of this disclosure, when auxiliary information is used for retransmission, the auxiliary network-side device enables joint channel estimation determination.

[0171] Figure 14 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 14, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S131.

[0172] In step S131, the network-side device receives a second message in response to the terminal scheduling the repeated transmission of msg3.

[0173] In embodiments of this disclosure, the second message is used to instruct the terminal on configuration parameters for the network-side device to perform joint channel estimation during the retransmission process.

[0174] In some embodiments of this disclosure, the second message may be the same as the first message, i.e., it may follow the same configuration parameters as the initial transmission or it may perform a joint channel instruction mechanism. Exemplaryly, the value of the time window length instructed based on the first message is applied to the initial transmission and repeated transmissions.

[0175] In some embodiments of this disclosure, the second message is the same as the first message portion. That is, when a terminal repeatedly sends msg3, it uses some of the initial transmission's configuration parameters or executes some of the joint channel instruction mechanisms. Exemplarily, the initial transmission specifies the length of the time window in which joint channel estimation is performed based on an explicit method, and the repeated transmission specifies the time window based on an implicit method. The length of the time window in which the initial transmission performs joint channel estimation and the time window for repeated transmissions can be enabled using the same message.

[0176] In some embodiments of this disclosure, the second message may be entirely different from the first message.

[0177] In embodiments of this disclosure, joint channel estimation may be referred to as inter-slot channel estimation.

[0178] Based on similar / similar concepts, embodiments of this disclosure further provide instruction methods.

[0179] Figure 15 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 15, the instruction method is applied to a network-side device and includes the following step S141.

[0180] In step S141, the first message is determined.

[0181] In embodiments of this disclosure, a first message is used by a terminal to determine configuration parameters for a network-side device to perform joint channel estimation, where the configuration parameters may include instructional information that instructs the network-side device to enable joint channel estimation and / or fixed parameter values ​​or parameter sets that determine the length of the time window for joint channel estimation. The parameter set or fixed parameter values ​​for determining the joint channel estimation time window can be instructed by a network-side device (e.g., a base station) or determined based on a communication protocol. The instructions from the network side include multiple instruction methods. See the following embodiments.

[0182] In some embodiments of this disclosure, a first message is used to instruct configuration information for joint channel estimation, where the configuration information includes instruction information. This instruction information is used to instruct a terminal that a network-side device enables joint channel estimation. Such embodiments may be implemented independently or in conjunction with any one of the other embodiments of this disclosure.

[0183] In some embodiments of this disclosure, a terminal receives a first message and decides that the network-side device enables joint channel estimation.

[0184] In embodiments of this disclosure, configuration information can be determined based on explicit signaling, such as Remaining Minimum System Information (RMSI). A terminal receives an RSMI, determines the first message carried by the RSMI, and further determines the configuration information contained in the first message. Here, the RSMI can be scheduled based on Downlink Control Information (DCI).

[0185] In embodiments of this disclosure, configuration information can be determined for uplink grant information (UL grant) within a Random Access Response (RAR) based on explicit signaling. The terminal determines whether the network-side device enables joint channel estimation based on the first message carried by the RAR UL grant.

[0186] In embodiments of the present disclosure, based on explicit signaling, a scrambled sequence of a Cyclic Redundancy Check (CRC) can determine configuration information for a DCI scrambled for a Random Access Radio Network Temporary Identifier (RA-RNTI). The terminal uses the scrambled sequence of the CRC to determine whether the network-side device enables joint channel estimation for the RA-RNTI DCI.

[0187] In embodiments of the present disclosure, the CRC may also determine configuration information for DCI scrambled for the Temporary Access Cell Radio Network Temporary Identifier (TC-RNTI) based on explicit signaling. In other words, the terminal determines that the network-side device enables joint channel estimation based on the DCI scrambled for the TC-RNTI by the CRC.

[0188] In embodiments of this disclosure, a network-side device can instruct a terminal whether or not to enable joint channel estimation based on an implicit instruction scheme. For example, if the terminal is instructed to repeatedly send Msg3, the network-side device decides to enable joint channel estimation.

[0189] In the embodiments of this disclosure, the embodiment in which the network-side device enables joint channel estimation can be applied to joint channel estimation of a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH).

[0190] Here, an explicit signaling instruction can be used to instruct the system to enable joint channel estimation. Explicit signaling may include radio resource control (RRC), system information block (SIB), DCI, MAC layer control element (MAC CE), etc.

[0191] In some embodiments of the present disclosure, a first message is used to determine time window length setting information for joint channel estimation, where the setting information includes a set of parameters or fixed parameter values ​​for determining the length of the time window for joint channel estimation. Such embodiments may be implemented independently or in conjunction with any one of the other embodiments of the present disclosure.

[0192] In one embodiment of the present disclosure, a terminal can determine a first message based on a predefined rule / communication protocol and determine a setting parameter for the length of the time window for joint channel estimation within the first message. In one embodiment, a parameter set for determining the time window length for joint channel estimation is determined based on a predefined rule / communication protocol, and this parameter set may be set for a cell. That is, a terminal in the cell uses a parameter set of a predefined rule / communication protocol. At a network-side device (e.g., a base station), a terminal determines one parameter in the determined parameter set based on a parameter set index indicated by the base station, and determines the time window length for joint channel estimation based on that parameter. In one embodiment, a fixed parameter value can be determined based on a predefined rule / communication protocol, and the length of the time window for joint channel estimation is determined using this fixed parameter value.

[0193] In another embodiment of the present disclosure, the terminal may determine a first message based on explicit instruction signaling and further determine a set of parameters or fixed parameter values ​​for determining the time window length of joint channel estimation, which are included in the configuration information.

[0194] In some embodiments of this disclosure, the explicit instruction signaling may be RSMI. A terminal can receive an RMSI and determine a first message carried by the RSMI. In one embodiment, based on the first message carried by the RSMI, a configuration parameter for determining the length of the joint channel estimation time window is determined. This configuration parameter includes a parameter set for the length of the joint channel estimation time window. The terminal further determines one parameter from the parameter set based on a parameter set index indicated by the network-side device, and determines the length of the joint channel estimation time window based on that parameter. In one embodiment, a fixed parameter value for indicating the length of the joint channel estimation time window is determined based on the first message carried by the RSMI. Herein, the embodiment may be configured to deal with all terminals in a cell. That is, a terminal in the cell receives an RMSI, determines a first message carried by the RSMI, and determines its joint channel estimation configuration parameter.

[0195] In some embodiments of this disclosure, the explicit scheme may be DCI scrambled by the CRC for RA-RNTI. The terminal can determine a setting parameter for the length of the joint channel estimation time window based on the DCI scrambled by the CRC for RA-RNTI. In one embodiment, the terminal determines, based on the DCI scrambled by the CRC for RA-RNTI (e.g., DCI format 1_0), that the setting parameter is an index of a parameter set for determining the length of the joint channel estimation time window, and further determines the length of the joint channel estimation time window based on that parameter set index. Here, the parameter set may be a list, configured by RMSI and / or configured in a protocol, and its index further indicated by DCI scrambled by the CRC for RA-RNTI or RAR of the uplink grant, and the terminal further determines a parameter in the parameter set by a network-side device-indicative parameter set index, and determines the length of the joint channel estimation time window based on that parameter. Here, the list of parameters may be a new list or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). In one embodiment, the CRC can specify a fixed parameter value by the DCI scrambled for RA-RNTI, and the terminal determines the length of the time window for joint channel estimation based on this fixed parameter value. Here, the embodiment may be a configuration for a set of terminals.

[0196] In some embodiments of this disclosure, the explicit scheme may be DCI scrambled by the CRC for TC-RNTI (e.g., DCI format 0_0). Based on the DCI scrambled by the CRC for TC-RNTI, the terminal determines a setting parameter for the length of the joint channel estimation time window. In one embodiment, the setting parameter determined based on the DCI scrambled by the CRC for TC-RNTI is an index of a parameter set for the length of the joint channel estimation time window, and the terminal further determines the length of the joint channel estimation time window based on that parameter set index. The parameter set may be a list, which is set by RMSI and / or in a protocol, and whose index is further indicated by the DCI scrambled by the CRC for TC-RNTI, and the terminal further determines a parameter in the parameter set based on the parameter set index indicated by the network-side device, and determines the length of the joint channel estimation time window based on that parameter. Exemplary, a parameter set includes multiple parameters, e.g., [2, 4, 8], and the specified parameter set index determines the time window length parameter for joint channel estimation within that parameter set. Here, the list of parameter sets may be a new list or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). In one embodiment, a fixed parameter value may be specified based on the DCI scrambled by the CRC for TC-RNTI. The terminal determines the time window length for joint channel estimation based on this fixed parameter value. This embodiment may target a specific terminal.

[0197] In some embodiments of this disclosure, the explicit method may be a RAR UL grant. Based on the RAR UL grant, the terminal determines a setting parameter for the length of the joint channel estimation time window. In one embodiment, the setting parameter determined based on the RAR UL grant is an index in a parameter set for the length of the joint channel estimation time window, and the terminal further determines the length of the joint channel estimation time window based on that parameter set index. The parameter set for the length of the joint channel estimation time window may be a single list, which is set by RMSI and / or in a protocol, and whose index is further indicated by the RAR UL grant, and the terminal further determines a parameter in the parameter set by the parameter set index indicated by the network-side device, and determines the length of the joint channel estimation time window based on that parameter. Exemplaryly, the parameter set includes multiple parameters, e.g., [2, 4, 8], and the indicated parameter set index determines the parameter for the length of the joint channel estimation time window in that parameter set. Here, the list of parameters may be a new list or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). In one embodiment, a fixed parameter value can be determined based on the RAR UL grant. The terminal determines the length of the time window for joint channel estimation based on this fixed parameter value. This embodiment may target a specific terminal.

[0198] In some other embodiments of this disclosure, the parameters for the time window length of joint channel estimation can be implicitly specified. For example, the parameters for the time window length of joint channel estimation can be implicitly determined based on the number of repeated transmissions. Exemplarily, the time window length of joint channel estimation is the number of slots corresponding to the number of repeated transmissions / N, where N is a positive integer, for example, N = 2. Of course, this is merely illustrative and not a specific limitation of this disclosure.

[0199] In some embodiments of this disclosure, a first message is used to instruct configuration information for joint channel estimation, which includes a set of parameters or fixed parameter values ​​to instruct the terminal to enable joint channel estimation and the length of the time window for joint channel estimation. Such embodiments may be implemented independently or in conjunction with any one of the other embodiments of this disclosure.

[0200] In one embodiment of the present disclosure, a terminal determines a first message based on an RMSI instruction provided by a network-side device, wherein the first message is a fixed value, and the terminal determines, based on the fixed value, whether the network side enables or disables joint channel estimation, and simultaneously, the fixed value can further determine the length of the joint channel estimation window. Exemplarily, if the fixed value is carried in the RMSI, the terminal determines that the network side has enabled joint channel estimation, and further determines the length of the joint channel estimation time window based on the fixed value; if the fixed value is not carried in the RMSI, the terminal determines that the network side has not enabled joint channel estimation. Exemplarily, if the fixed value is carried in the RMSI and the fixed value is 0 or 1, the terminal determines that the network side has disabled joint channel estimation; if the fixed value is carried in the RMSI and the value is greater than 1, the terminal determines that the network side has enabled joint channel estimation, and further determines the length of the joint channel estimation time window based on the fixed value.

[0201] In another embodiment of the present disclosure, configuration information instructing joint channel estimation can be determined based on DCI scrambled for RA-RNTI (e.g., DCI format 1_0) by the CRC. In one embodiment, the configuration information includes a fixed value for enabling or disabling joint channel estimation. If the fixed value is 0 or 1, it is determined to disable joint channel estimation. If the fixed value is 1 or any other value other than 0, it is determined to enable joint channel estimation and to determine the length of the joint channel estimation time window based on the fixed value. In another embodiment, the configuration information includes a parameter set for the length of the joint channel estimation time window. This parameter set is configured by RMSI or defined by the protocol, and its parameter set index is further indicated by DCI scrambled for RA-RNTI by the CRC. Based on the parameter set index indicated by the network-side device, the terminal determines one parameter in the parameter set and, based on that parameter, determines whether to enable joint channel estimation and the length of the joint channel estimation time window. The parameter set may be a single table, a new list, or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). Exemplarily, assuming the parameters included in the parameter set are [0, 2, 4, 8], a parameter of 0 means that joint channel estimation is disabled, and if the parameter is any one of the remaining parameters, it is decided to enable joint channel estimation and to determine that parameter as the length of the time window for joint channel estimation. Of course, parameter 0 may also be parameter 1, and if parameter 1 is indicated, it is decided not to enable joint channel estimation, and this is not specifically limited. The embodiment may be a setting for a set of terminals.

[0202] In further embodiments of the present disclosure, configuration information instructing joint channel estimation can be determined based on DCI (e.g., DCI format 0_0) scrambled by the CRC for TC-RNTI. In one embodiment, the configuration information includes a fixed value for enabling or disabling joint channel estimation. If the fixed value is 0 or 1, it is determined to disable joint channel estimation. If the fixed value is 1 or any other value other than 0, it is determined to enable joint channel estimation and to determine the fixed value as the length of the joint channel estimation time window. In another embodiment, the configuration information includes a parameter set for the length of the joint channel estimation time window. This parameter set is configured by RMSI or defined by the protocol, and its parameter set index is further indicated by DCI scrambled by the CRC for RA-RNTI. Based on the parameter set index indicated by the network-side device, the terminal determines one parameter from the parameter set, and based on that parameter, determines whether to enable joint channel estimation and the length of the joint channel estimation time window. The parameter set may be a single table, a new list, or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). For example, the parameters in the parameter set are [0, 2, 4, 8], where a parameter of 0 indicates that joint channel estimation is prohibited, and if the parameter is any one of the remaining parameters, it is decided to enable joint channel estimation and determine the length of the time window for joint channel estimation based on that parameter. Of course, parameter 0 may also be parameter 1, and indicating that the parameter is 1 indicates that joint channel estimation is not enabled, and this is not specifically limited.

[0203] In further embodiments of the present disclosure, configuration information instructing joint channel estimation can be determined based on DCI (e.g., DCI format 0_0) scrambled by the CRC for TC-RNTI. In one embodiment, the configuration information includes a fixed value for enabling or disabling joint channel estimation. If the fixed value is 0 or 1, it is determined to disable joint channel estimation. If the fixed value is 1 or any other value other than 0, it is determined to enable joint channel estimation and to determine the fixed value as the length of the joint channel estimation time window. In another embodiment, the configuration information includes a parameter set for the length of the joint channel estimation time window. This parameter set is configured by RMSI or defined by the protocol, and its parameter set index is further indicated by DCI scrambled by the CRC for RA-RNTI. Based on the parameter set index indicated by the network-side device, the terminal determines one parameter from the parameter set, and based on that parameter, determines whether to enable joint channel estimation and the length of the joint channel estimation time window. The parameter set may be a single table, a new list, or an existing list, such as a Modulation and Coding Scheme (MCS) / TDRA table. If an existing list is used, one field must be added to the existing list (e.g., a new column). For example, the parameters in the parameter set are [0, 2, 4, 8], where a parameter of 0 indicates that joint channel estimation is prohibited, and if the parameter is any one of the remaining parameters, it is decided to enable joint channel estimation and determine the length of the time window for joint channel estimation based on that parameter. Of course, parameter 0 may also be parameter 1, and indicating that the parameter is 1 indicates that joint channel estimation is not enabled, and this is not specifically limited.

[0204] In embodiments of this disclosure, as described above, the network-side device determines a parameter set or fixed parameter value for the length of the time window for joint channel estimation. Here, each parameter or fixed parameter value in the parameter set can be determined based on the number of repeated transmissions of terminal Msg3. For example, each parameter or fixed parameter value in the parameter set may be determined to be a common factor for all selectable number of repeated transmissions. Exemplarily, if the selectable number of repeated transmissions is 4 or 8, the parameters in the parameter set may be determined to be 2 or 4. Alternatively, the set fixed parameter value may be determined to be 4. Of course, this is merely an example and not a specific limitation to this disclosure.

[0205] The instruction method provided by the embodiments of this disclosure can instruct a terminal to enable network-side device joint channel estimation and to specify the time window for performing joint channel estimation. This solves the problem of not being able to instruct a terminal to enable joint channel estimation and to specify the time window for performing joint channel estimation.

[0206] In the embodiments of this disclosure, the terminal decides to enable joint channel estimation based on the received configuration information and obtains parameters used for the length of the time window of the joint channel estimation. Based on the obtained parameters, joint channel estimation is performed, and the following embodiments can be used.

[0207] Figure 16 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 16, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following steps S151 to S152.

[0208] In step S151, the first parameter is determined in the parameter set based on the set parameters, or a fixed parameter value is determined as the first parameter.

[0209] In step S152, the length of the time window for performing joint channel estimation is determined based on the first parameter.

[0210] In the embodiments of this disclosure, the first parameter is determined in the parameter set, or a fixed parameter value is determined as the first parameter, as in the determination of the setting parameters described above.

[0211] Based on the first parameter, the length of the time window for performing joint channel estimation is determined. For the sake of clarity, this disclosure refers to the parameter indicated in the parameter set based on the configuration information as the first parameter.

[0212] In an exemplary embodiment of this disclosure, a configuration parameter is obtained to acquire a set of parameters for determining the length of the time window for joint channel estimation, and a parameter within the parameter set indicated by the base station is determined as the length of the time window for performing joint channel estimation. Alternatively, a configuration parameter is obtained to acquire a fixed parameter value for determining the time window for joint channel estimation, and this parameter value is determined as the length of the time window for performing joint channel estimation. Exemplaryly, the set of parameters for determining the length of the time window for joint channel estimation includes, for example, multiple parameters which are 2, 4, and 8, respectively. If the parameter indicating the length of the time window for joint channel estimation is 4, then the duration for performing joint channel estimation is determined to be 4. Here, the duration may be a slot, i.e., the length of the time window for joint channel estimation is four consecutive slots. In other words, the network-side device repeats and performs joint channel estimation once for every four slots. Here, the duration may be other scheduling time units, and in embodiments of this disclosure which are not specifically limited herein, the first parameter is determined as the time window for performing joint channel estimation, and if the transmission time for the number of repetitions is shorter than the length of the time window for joint channel estimation, joint channel estimation can be performed based on a different policy. See the following embodiments.

[0213] In the embodiments of this disclosure, the terminal determines a transmission time corresponding to the number of repetitions. For example, the repetitive message is Msg3, and the number of repetitions of Msg3 is 2. If the determined first parameter is 4, the transmission time corresponding to the number of repetitions is less than the first parameter, and it is decided to perform joint channel estimation based on the first policy.

[0214] In some embodiments of this disclosure, performing joint channel estimation based on the first policy includes canceling joint channel estimation; that is, canceling enabling joint channel estimation if the transmission time is less than the first parameter.

[0215] In some embodiments of this disclosure, performing joint channel estimation based on the first policy includes redetermining the length of the time window for joint channel estimation based on a predefined rule, and then performing joint channel estimation based on the redetermined length of the time window.

[0216] For example, the length of the time window for joint channel estimation can be determined based on predefined rules, where the transmission time for the number of repeated transmissions or half of the transmission time is the length of the actual time window for joint channel estimation. The transmission time for the number of repeated transmissions can be determined as the length of the time window for performing joint channel estimation. Furthermore, a fixed value indicated by the communication protocol can be determined as the length of the time window for performing joint channel estimation. Furthermore, a value specified by the network-side device based on configuration parameters can be determined as the length of the time window for performing joint channel estimation. Furthermore, a value that is close to a specified value and smaller than the transmission time corresponding to the number of repeated transmissions can be determined as the time window for performing joint channel estimation.

[0217] In some embodiments of this disclosure, performing joint channel estimation based on the first policy involves redetermining the length of the joint channel estimation time window based on the transmission time of the number of repetitions. Exemplarily, the duration of the joint channel estimation is specified as a common factor of all selectable repetitions. Based on this common factor, the time window in which the joint channel estimation is performed is determined.

[0218] In embodiments of this disclosure, the transmission time corresponding to the number of blind repeated transmissions is determined, and if the remaining transmission time after performing joint channel estimation based on the transmission time is shorter than the length of the time window for the next joint channel estimation, it is decided to perform joint channel estimation using the second policy.

[0219] In some embodiments of this disclosure, performing joint channel estimation based on the second policy includes canceling joint channel estimation. That is, if the remaining transmission time after performing joint channel estimation with respect to transmission time is shorter than the length of the time window for performing the next joint channel estimation, it is decided to cancel enabling joint channel estimation.

[0220] In some embodiments of this disclosure, performing joint channel estimation based on the second policy includes canceling joint channel estimations for slots within the remainder of the quotient between the transmission time and the first parameter. In other words, it cancels joint channel estimations where the transmission time after the joint channel estimation is shorter than the length of the time window for the next joint channel estimation.

[0221] In some embodiments of this disclosure, performing joint channel estimation based on a second policy includes redetermining the length of the joint channel estimation time window based on predefined rules and performing joint channel estimation based on the redetermined joint channel estimation time window length. Furthermore, the terminal determines the length of the time window for all overlapping joint channel estimations based on predefined rules. The terminal may subdivide the length of the joint channel estimation time window based on the transmission time corresponding to the number of repeated transmissions.

[0222] In some embodiments of this disclosure, performing joint channel estimation based on a second policy includes determining, based on a predefined rule, that the time corresponding to the remainder of the quotient between the transmission time and the first parameter is the length of the time window for joint channel estimation. The terminal performs joint channel estimation based on the length of the redetermined time window. The terminal determines, based on a predefined rule, the remainder of the quotient between the transmission time and the first duration, i.e., the remaining transmission time after performing joint channel estimation. For the remaining transmission time, it can be determined that the duration for performing joint channel estimation coincides with the remaining transmission time. For example, if the repeated transmission has 14 slots and the first parameter has 4 slots, the remainder is 2, and the length of the time window for performing the last joint channel estimation is determined to be 2.

[0223] In some embodiments of this disclosure, performing joint channel estimation based on the second policy further includes redetermining the length of the time window for performing joint channel estimation based on the number of repeated transmissions and the length of the time window for joint channel estimation. Exemplaryly, a division is performed based on each selectable number of repeated transmissions to determine the length of the time window for selectable joint channel estimation.

[0224] In one exemplary embodiment of this disclosure, the transmission time corresponding to repeated transmissions is determined in the configuration parameters. Furthermore, the transmission time is calculated based on a predefined calculation rule, and the resulting calculated value (relative value) is determined as a second parameter. The second parameter is determined as the length of the time window in which joint channel estimation is performed.

[0225] In an embodiment of the present disclosure, a quotient operation can be performed on the transmission time based on a predefined parameter value. For example, based on the fact that the predefined parameter value is 4, the transmission time corresponding to the determined number of repeated transmissions is 12, and that time may be a slot. It is determined that the duration for performing joint channel estimation is 3. In other words, the network-side device can repeatedly perform joint channel estimation once every three slots.

[0226] In some embodiments of the present disclosure, when determining the relative value of the number of repeated transmissions as the duration for performing joint channel estimation, there are cases where the second parameter is smaller than the first numerical value and there is a remainder after performing a quotient operation on the second parameter.

[0227] In an embodiment of the present disclosure, when the second parameter is smaller than the first numerical value, joint channel estimation is performed based on the second policy. Here, the first numerical value may be 1. Exemplarily, the transmission time corresponding to repeated transmission is 2, and the duration for performing joint channel estimation instructed by the network-side device is 4, where the time may be a slot. When the second duration is 2 / 4, the network-side device cannot perform joint channel estimation.

[0228] In some embodiments of the present disclosure, performing joint channel estimation based on the third policy includes canceling joint channel estimation. That is, when the second parameter is smaller than the first numerical value, it is determined to cancel enabling joint channel estimation.

[0229] In some embodiments of the present disclosure, performing joint channel estimation based on a third policy includes being able to re-determine a second parameter based on a predefined rule. Exemplarily, in the repetition of Msg3, the duration for performing joint channel estimation is re-determined. For example, it may be half of the duration granularity, or it is determined that it is a fixed value smaller than the transmission time of the repeated transmission.

[0230] In some embodiments of the present disclosure, performing joint channel estimation based on a third policy includes re-determining the length of the time window for performing joint channel estimation based on the transmission time of the repeated transmission.

[0231] In step S91, in response to the existence of a remainder in the second parameter, joint channel estimation is performed based on a fourth policy.

[0232] In an embodiment of the present disclosure, when there is a remainder after performing a quotient operation on the second parameter, the fourth policy can be executed. For example, when the transmission time of the repeated transmission is 14 and the relative value of the repetition is 4, there may be a case where there is a remainder in 14 / 4. The time may be a slot.

[0233] In some embodiments of the present disclosure, performing joint channel estimation based on a fourth policy includes determining a lower limit of the time granularity for performing joint channel estimation. Exemplarily, it can be selected such that the duration is three slots. In other words, when actually performing joint channel estimation, the network-side device can perform joint channel estimation five times. The duration of the first four joint channel estimations is three slots, and the duration of the last joint channel estimation is two slots. Or the network-side device can perform joint channel estimation four times, and the last two remaining slots do not perform joint channel estimation.

[0234] In some embodiments of this disclosure, performing joint channel estimation based on the fourth policy involves determining a quotient value that is an integer multiple of the second duration; that is, determining the integer value of the quotient operation as the length of the time window in which the joint channel estimation is performed.

[0235] In some embodiments of this disclosure, performing joint channel estimation based on the fourth policy includes redetermining the second duration based on a predefined rule. In other words, a fixed value is redetermined based on a predefined rule, and a relative value divisible by the transmission time of repeated transmissions is determined relative to that fixed value as the length of the time window for performing joint channel estimation. Here, the relative value may be determined by the protocol or indicated by the network side, and the relative value may be less than or greater than the fixed value.

[0236] In some embodiments of this disclosure, performing joint channel estimation based on policy 4 includes redetermining the length of the time window in which joint channel estimation is performed based on the transmission time of repeated transmissions and the duration granularity of the joint channel estimation.

[0237] In some embodiments of this disclosure, performing joint channel estimation based on the first policy includes canceling joint channel estimation, that is, deciding to cancel enabling joint channel estimation in the case where there is a remainder in the quotient operation.

[0238] Figure 17 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 17, the instruction method is applied to a terminal, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S161.

[0239] In step S161, auxiliary information is received.

[0240] In embodiments of this disclosure, auxiliary information is used by the network-side device to determine configuration parameters for performing joint channel estimation. Here, the auxiliary information may be speed information, etc. Different speed information represents different channel state change information. Based on the channel state change information reported by the terminal, the network side can be assisted in determining whether or not to enable joint channel estimation and the length of the time window for performing joint channel estimation.

[0241] Figure 18 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 18, the instruction method is applied to a network-side device, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S171.

[0242] In step S171, auxiliary information is received based on random access message 1.

[0243] In embodiments of this disclosure, a network-side device can receive auxiliary information based on different Physical Random Access Channel (PRACH) resource groups in Msg1 to determine different speed information. PRACH resources may be time-frequency resources, frequency-domain resources, code-domain resources, etc. A terminal can send a preamble based on the group corresponding to its speed to inform the terminal of the current channel status.

[0244] Figure 19 is a flowchart of an instruction method shown in an exemplary embodiment. As shown in Figure 19, the instruction method is applied to a network-side device, and this embodiment can be implemented independently or in conjunction with any one of the other embodiments of this disclosure. It includes the following step S181.

[0245] In step S181, supplementary information is received based on the DMRS.

[0246] In embodiments of this disclosure, the network-side device determines the terminal's channel status by receiving different speed information based on different DMRSs.
