[0107] To better describe any of the disclosure embodiments, an application scenario of an access control is exemplarily illustrated in an embodiment of the disclosure.
[0108] Reference is made to Figure 1 which shows a structure schematic diagram of a wireless communication system provided by an embodiment of the disclosure. As shown in Figure 1 , the wireless communication system is a communication system based on a cellular mobile communication technology, and the wireless communication system can include a plurality of terminals 11 and a plurality of base stations 12.
[0109] The terminal 11 can be a device that provides voice and / or data connectivity to a user. The terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or called "cellular" phone), and a computer with an Internet of Things terminal, for example, which can be a fixed, portable, pocket, handheld, built-in, or vehicle-mounted device. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment. Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 can also be a vehicle-mounted device, for example, it can be a vehicle-mounted computer with wireless communication function or a wireless terminal of an external vehicle-mounted computer. Alternatively, the terminal 11 can also be a roadside device, for example, it can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.
[0110] The base station 12 can be a network side device in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can also be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can also be a next generation system of the 5G system. In the 5G system, the access network can be referred to as an NG-RAN (New Generation-Radio Access Network).
[0111] The base station 12 can be an evolved NodeB (eNB) in a 4G system. Alternatively, the base station 12 can be a base station (gNB) in a 5G system using a centralized and distributed architecture. When the base station 12 uses a centralized and distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer; and the distributed unit is provided with a protocol stack of a physical (PHY) layer. The specific implementation of the base station 12 is not limited in the embodiments of the present disclosure.
[0112] The base station 12 and the terminal 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new radio (NR) air interface; or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.
[0113] In some embodiments, the terminals 11 can also establish an E2E (End to End) connection. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication, and the like.
[0114] In some embodiments, the wireless communication system can also include a network management device 13.
[0115] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.
[0116] For cellular mobile communication systems, network coverage performance is crucial. This directly impacts operators' network deployment. Dense network deployment results in better coverage but increases operator costs. Sparse network deployment leads to poorer coverage.
[0117] To improve network coverage performance, retransmission can be employed. For example, retransmission in the time domain can improve uplink coverage. However, this method leads to lower spectrum resource utilization and introduces additional latency. In some embodiments, joint channel estimation using DMRS transmitted between different time slots or within the same time slot for the same user on the PUSCH (Physical Uplink Shared Channel) or PUCCH (Physical Uplink Control Channel) can improve channel estimation accuracy, thereby enhancing network coverage performance. In other words, by supporting DMRS binding across time slots or across retransmissions, the coverage quality and range of PUSCH and PUCCH can be enhanced.
[0118] For joint channel estimation based on DMRS binding across time slots or across repeated transmissions, the terminal and the base station need to meet certain power consistency and phase continuity conditions.
[0119] In this regard, such as Figure 2 As shown, this disclosure provides a configuration method for joint channel estimation, which is executed by a terminal, including:
[0120] Step S101: receiving configuration information of joint channel estimation; wherein the configuration information is used for the terminal to perform the joint channel estimation.
[0121] In the embodiments of the present disclosure, the terminal can obtain the configuration information of joint channel estimation from the network device. Here, the network device can be a device with the function of information interaction with the terminal, such as a base station or a core network device. The terminal can determine the configuration of the DMRS required for joint channel estimation according to the configuration information. Or, the terminal can determine whether to perform joint channel estimation or the time period corresponding to the joint channel estimation based on the configuration information.
[0122] The terminal performs the corresponding joint channel estimation by obtaining the configuration information provided by the network device, which can facilitate the terminal to perform the above-mentioned joint channel estimation based on the condition that the configuration information is satisfied, improve the accuracy of channel estimation, and further improve the coverage performance of the network.
[0123] In some embodiments, the configuration information at least includes:
[0124] Time range information of DMRS binding required by the terminal to perform the joint channel estimation.
[0125] DMRS is widely used in physical channels in various communication scenarios, such as downlink PBCH (Physical Broadcast Channel), PDCCH (Physical Downlink Control Channel) and PDSCH (Physical Downlink Shared Channel), and uplink PUCCH and PUSCH, etc., for demodulation of uplink and downlink data. For a specific terminal, it can be used for channel estimation of wireless channel.
[0126] In the embodiments of the present disclosure, cross-slot or cross-repetition transmission DMRS binding can be used to realize joint channel estimation. That is, the above-mentioned time range information can represent that the time period of joint channel estimation spans multiple slots or retransmission ranges, and in the time period corresponding to the time range information, a fixed DMRS sequence setting can be used, thereby facilitating joint channel estimation and improving the accuracy of channel estimation.
[0127] In addition, the configuration information can also include configuration information of DMRS timing or other parameters, so as to facilitate the terminal to perform joint channel estimation according to the DMRS based on the configuration information.
[0128] In some embodiments, as shown in the method further includes: Figure 3
[0129] Step S201, reporting DMRS bundling capability information supported by the terminal, wherein the DMRS bundling capability information is used for the network device to determine configuration information of the joint channel estimation.
[0130] By supporting DMRS bundling across slots or across repetitions, joint channel estimation is achieved, which requires the terminal to maintain power consistency and phase continuity within a certain time range, and requires the terminal to support the requirements of power and phase performance. Therefore, the terminal can report the DMRS bundling capability information supported by itself to inform the network device whether it supports joint channel estimation, or to inform the network device the range of power and phase performance supported by itself.
[0131] In this way, the network device can make corresponding configuration based on the capability reported by the terminal. If the capability reported by the terminal indicates that it cannot support joint channel estimation, the network device can not configure joint channel estimation. If the capability reported by the terminal indicates that it can support the above joint channel estimation, the network device can provide corresponding configuration information to facilitate the terminal to perform joint channel estimation.
[0132] In some embodiments, the DMRS bundling capability information includes:
[0133] indication information of whether the DMRS bundling capability of the terminal supports joint channel estimation.
[0134] In the embodiments of the present disclosure, the DMRS bundling capability information reported by the terminal can be used to inform the network device whether the terminal supports joint channel estimation. The terminal can determine whether to support joint channel estimation based on its own DMRS bundling capability.
[0135] In addition, the terminal can also determine the time period in which it supports joint channel estimation according to its own DMRS bundling capability, and report it to the network device.
[0136] Of course, the terminal can also directly report the related parameters of its own DMRS bundling capability to the network device, and the network device determines whether the terminal supports joint channel estimation.
[0137] In some embodiments, the method further includes:
[0138] determining indication information of whether the DMRS bundling capability of the terminal supports joint channel estimation based on an agreement of a protocol.
[0139] In the embodiments of the present disclosure, the DMRS bundling capability information of the terminal is used to indicate whether the terminal supports joint channel estimation, therefore, the terminal can determine whether to support based on its own DMRS bundling capability, and then report.
[0140] The judgment standard of the terminal can be determined according to the agreement, and therefore, the terminal can determine whether the DMRS binding capability of the terminal meets the joint channel estimation condition based on the agreement.
[0141] In some embodiments, the DMRS binding capability includes one or more of the following:
[0142] The power consistency of the terminal; and
[0143] The phase continuity of the terminal.
[0144] The DMRS binding capability can include the capability of the terminal to support parameters such as power and phase. For example, the terminal determines whether the DMRS binding capability of the terminal meets the power consistency and phase continuity requirements required for joint channel estimation based on the threshold range specified by the agreement, and reports the network device, so as to facilitate the network device to make corresponding configuration based on the report of the terminal.
[0145] In the embodiments of the present disclosure, the agreement can specify that the terminal needs to meet both the power consistency condition and the phase continuity condition, that is, the power of the terminal meets the predetermined power consistency condition, and at the same time, the phase meets the predetermined phase continuity condition, so as to meet the condition of joint channel estimation.
[0146] The DMRS binding capability includes one or more of the following:
[0147] The maximum and minimum values of the power supported by the terminal;
[0148] The maximum absolute value of the fluctuation deviation of the power of the terminal within a predetermined time range; and
[0149] The standard deviation or variance value of the fluctuation deviation of the power of the terminal within a predetermined time range.
[0150] The power consistency information can be represented from the range of the power supported by the terminal and the range of the power fluctuation. The terminal can determine whether the terminal meets the requirement of joint channel estimation by judging whether the maximum and minimum values of the power supported by the terminal and the fluctuation deviation meet the threshold condition required for joint channel estimation.
[0151] It should be noted that whether the power consistency information meets the requirement of joint channel estimation can be determined by the agreement. Therefore, the terminal can also determine whether the requirement of joint channel estimation is met based on the power consistency information of the terminal, and report to the network device, so as to facilitate the network device to make corresponding configuration.
[0152] Exemplarily, the protocol can pre-agree the minimum and maximum values of the power of the terminal within a certain time range for joint channel estimation, the maximum absolute value of the relative deviation of the power fluctuation within a certain time range, and the maximum value of the variance or standard deviation of the power fluctuation within a certain time range, etc. In this way, whether the terminal meets the condition for joint channel estimation can be determined based on whether the power consistency information of the terminal meets the range agreed by the protocol.
[0153] The DMRS bundling capability described above can further include one or more of the following:
[0154] The maximum and minimum values of the phase supported by the terminal;
[0155] The maximum absolute value of the deviation of the phase fluctuation of the terminal within a predetermined time range; and
[0156] The standard deviation or variance value of the deviation of the phase fluctuation of the terminal within a predetermined time range.
[0157] Similar to the power consistency-related parameters, the terminal can report its own capability by determining whether the maximum and minimum values of the phase supported by the terminal and the deviation meet the threshold conditions required for joint channel estimation, thereby facilitating the network device to issue corresponding configuration information.
[0158] Of course, the requirement of the phase continuity information for joint channel estimation can also be agreed by the protocol. Therefore, the terminal can also determine whether the threshold conditions specified by the protocol are met based on the phase consistency-related parameters of the terminal, and report them to the network device for corresponding configuration by the network device.
[0159] Exemplarily, the protocol can pre-agree the minimum and maximum values of the phase of the terminal within a certain time range for joint channel estimation, the maximum absolute value of the relative deviation of the phase fluctuation within a certain time range, and the maximum value of the variance or standard deviation of the phase fluctuation within a certain time range, etc. In this way, whether the terminal meets the condition for joint channel estimation can be determined based on whether the phase continuity information of the terminal meets the range agreed by the protocol.
[0160] In some embodiments, the DMRS bundling capability information supported by the terminal reported by the terminal includes:
[0161] The terminal capability report information carrying the DMRS bundling capability information is reported.
[0162] In the embodiments of the present disclosure, the terminal can carry the DMRS bundling capability information described above in the terminal capability report information and report it to the network device. The terminal capability report information can also be used to carry other capabilities of the terminal. Therefore, the network device can determine the configuration information for the joint channel estimation based on the terminal capability report information, and can also perform configuration of other information and resource scheduling for data transmission of the terminal, etc.
[0163] In this way, the terminal reports the DMRS bundling capability information without additional signaling transmission, and the existing terminal capability reporting information can be used for reporting.
[0164] In some embodiments, the DMRS bundling capability information supported by the terminal includes:
[0165] The auxiliary information is reported to indicate the DMRS bundling capability information.
[0166] In the embodiments of the present disclosure, the DMRS bundling capability information of the terminal can be reported through auxiliary information. The auxiliary information can be reported as a separate signaling or can be carried in other existing signaling. The auxiliary information can be explicitly carried in the signaling or can be implicitly indicated through other information.
[0167] In some embodiments, the auxiliary information used to indicate the DMRS bundling capability information includes:
[0168] The dedicated information carrying the auxiliary information is explicitly reported; or
[0169] The predetermined information carrying the auxiliary information is implicitly reported.
[0170] Here, the dedicated information can include auxiliary information carried in a dedicated information field of predetermined signaling or auxiliary information dedicated information carried in a dedicated signaling. The dedicated information can be dedicated to carrying the auxiliary information, and the content of the auxiliary information can include the DMRS capability information of the terminal. Reporting the DMRS bundling capability of the terminal through the dedicated information can facilitate the network device to determine the configuration information of the terminal for joint channel estimation.
[0171] In addition, the predetermined information can be information used to report other content, rather than signaling dedicated to reporting the auxiliary information. The auxiliary information reported by the terminal is implicitly carried, that is, the auxiliary information is implicitly indicated by using different conditions of the original information content, signaling format, encoding method, scrambling method, and retransmission number of the predetermined information. For example, the auxiliary information can include information indicating whether the DMRS bundling capability of the terminal meets the condition for joint channel estimation. If the DMRS bundling capability of the terminal meets the condition for joint channel estimation, the auxiliary information is reported through a first encoding method of the predetermined information; if the DMRS bundling capability of the terminal does not meet the condition for joint channel estimation, the auxiliary information is reported through a second encoding method of the predetermined information. In this way, the network device only needs to determine whether the DMRS bundling capability of the terminal meets the condition for joint channel estimation through the encoding method of the predetermined information, and then provide corresponding configuration information.
[0172] In some embodiments, the method further includes:
[0173] perform the joint channel estimation based on the received configuration information of the joint channel estimation.
[0174] After receiving the configuration information provided by the network device, the terminal can perform uplink transmission based on the scheduling of the network device, and perform corresponding joint channel estimation based on the configuration information in the process of uplink transmission.
[0175] As shown in Figure 4 The embodiment of the present disclosure provides a configuration method of joint channel estimation, which is executed by a network device, and includes:
[0176] Step S301, issuing configuration information of joint channel estimation of a terminal; wherein the configuration information is used for the terminal to perform the joint channel estimation.
[0177] In the embodiment of the present disclosure, the network device can configure the joint channel estimation of the terminal, and therefore issue corresponding configuration information to the terminal. Here, the network device can be a device with information interaction function with the terminal, such as a base station or a core network device. In this way, the terminal can perform joint channel estimation based on the configuration information. For example, the terminal can determine the configuration of DMRS for joint channel estimation according to the configuration information, and perform joint channel estimation based on DMRS. Or, the terminal can determine whether to perform joint channel estimation or the time period corresponding to joint channel estimation based on the configuration information.
[0178] The network device provides configuration information to facilitate the terminal to perform corresponding joint channel estimation under the condition of meeting the joint channel estimation, thereby improving the accuracy of channel estimation and further improving the coverage performance of the network.
[0179] In some embodiments, the configuration information at least includes:
[0180] Time range information of DMRS binding required by the terminal to perform the joint channel estimation.
[0181] DMRS exists widely in physical channels of various communication scenarios, such as PBCH, PDCCH and PDSCH of downlink, and PUCCH and PUSCH of uplink, etc., which are used for demodulation of uplink and downlink data. For a specific terminal, it can be used for channel estimation of wireless channel.
[0182] In the embodiment of the present disclosure, cross-slot or cross-repetition transmission DMRS binding can be used to realize joint channel estimation. That is, the above-mentioned time range information can represent a time period spanned by multiple time slots or retransmission ranges for joint channel estimation. In the time period corresponding to the time range information, a fixed DMRS sequence setting can be used, thereby facilitating joint channel estimation and improving the accuracy of channel estimation.
[0183] In some embodiments, the configuration information comprises N sets, where N is an integer greater than or equal to 1.
[0184] In the embodiments of the present disclosure, the network device can configure one or more sets of configuration information for the terminal, and the terminal can use different configuration information for joint channel estimation in different cases. In addition, the network device can also configure the same configuration information or different configuration information for multiple terminals, for example, configuring the same configuration information for all terminals in a cell, or configuring the same configuration information for grouped terminals.
[0185] In the embodiments of the present disclosure, the network device can configure the configuration information for joint channel estimation of the terminal based on different configuration granularities. Specifically, the network device can use one or more of different information such as different SCS, PUCCH, PUSCH, traffic type, frequency modulation mode, DMRS mode, or different DRMS binding capability information reported by the terminal as the configuration granularity, and correspondingly determine N sets of configuration information. N can be one set or multiple sets, and the N sets of configuration information are issued.
[0186] The terminal can activate one or more sets of the N sets of configuration information based on the configuration of the network device, and use the activated configuration information in the process of joint channel estimation.
[0187] In some embodiments, as shown in Figure 5 The method further comprises:
[0188] In step S401, activation information for activating the configuration information is issued, where the activation information is used to activate the terminal to support M sets of configuration information, and M is a positive integer less than or equal to N.
[0189] The network device can also trigger the configuration information effective for the terminal by issuing activation information, for example, by using the activation information to trigger the terminal to support M sets of configuration information in the same period, and the terminal can use the activated configuration information for corresponding joint channel estimation based on the transmission condition.
[0190] Of course, the number of configuration information activated by the network device through the activation information is not greater than the total number of configuration information issued by the network device. In this way, the network device can configure multiple sets of configuration information for the terminal based on different parameters, and then activate at least part of the configuration information based on different requirements or transmission states, without the need for repeated configuration.
[0191] In some embodiments, the activation information for activating the configuration information comprises:
[0192] The activation information of the configuration information is delivered by DCI or MAC-CE.
[0193] The activation information can be delivered by DCI or MAC-CE, and the activation information is carried in a newly added information field to inform the terminal which configuration information is activated, so as to facilitate the terminal to determine the currently available configuration information.
[0194] In some embodiments, the configuration information for enabling the terminal to perform joint channel estimation comprises:
[0195] The configuration information is delivered by radio resource control (RRC) signaling.
[0196] The base station can carry the configuration information by RRC signaling and deliver it to the terminal, or carry the configuration information by other signaling and deliver it to the terminal. For example, by RRC semi-static configuration, RRC pre-configuration combined with DCI indication of activation, or by MAC pre-configuration combined with DCI indication of activation, and the like.
[0197] In some embodiments, as shown in Figure 6 The method further comprises:
[0198] Step S501: receiving DMRS binding capability information reported by the terminal;
[0199] Step S502: determining the configuration information for joint channel estimation according to the DMRS binding capability information.
[0200] By supporting DMRS binding across slots or across repeated transmissions to realize joint channel estimation, the terminal needs to maintain power consistency and phase continuity within a certain time range, and the terminal needs to support the requirements of power and phase performance. Therefore, the network device can obtain the DMRS binding capability information supported by the terminal to determine whether the terminal supports joint channel estimation, or obtain the range of power and phase performance supported by the terminal.
[0201] In this way, the network device can configure the terminal based on the reported capability. If the terminal capability obtained by the network device indicates that the terminal cannot support joint channel estimation, the network device can not configure joint channel estimation. If the terminal capability obtained by the network device indicates that the terminal can support joint channel estimation, the network device can provide corresponding configuration information to facilitate the terminal to perform joint channel estimation.
[0202] In some embodiments, the configuration information for enabling the terminal to perform joint channel estimation comprises:
[0203] determining configuration information of the terminal for joint channel estimation in response to the DMRS bundling capability information indicating that the terminal meets the condition of joint channel estimation; or
[0204] determining whether the DMRS bundling capability information meets a threshold range agreed by a protocol; and determining configuration information of the terminal for joint channel estimation in response to the DMRS bundling capability information meeting the threshold range agreed by the protocol.
[0205] In the embodiments of the present disclosure, the condition that the terminal needs to meet for joint channel estimation can be agreed by a protocol, including the limitation of phase and power, etc.
[0206] For example, the protocol can agree that the terminal needs to meet the maximum and minimum values of phase and power within a certain time range, the maximum absolute value of the relative deviation of phase fluctuation and the maximum absolute value of the relative deviation of power fluctuation within a certain time range, and the maximum value of the variance or standard deviation of phase fluctuation and the maximum value of the variance or standard deviation of power fluctuation within a certain time range, etc.
[0207] If the DMRS bundling capability information reported by the terminal indicates that the terminal meets the above threshold range agreed by the protocol, joint channel estimation can be performed, and therefore the configuration information of the terminal for joint channel estimation can be issued.
[0208] In the embodiments of the present disclosure, if the DMRS bundling capability information reported by the terminal is used to indicate whether the terminal meets the condition of joint channel estimation or the period of time in which the terminal supports joint channel estimation, the network device determines the corresponding configuration information when the DMRS bundling capability information indicates that the terminal meets the condition, and determines not to configure the terminal when the DMRS bundling capability information indicates that the terminal does not meet the condition.
[0209] If the DMRS bundling capability information reported by the terminal is used to inform the network device of the capability parameter of the terminal, the network device can determine whether the capability parameter reported by the terminal meets the threshold condition of joint channel estimation based on the agreement of the protocol, and then perform corresponding configuration.
[0210] In some embodiments, the method further comprises:
[0211] scheduling uplink channel transmission of the terminal in response to the terminal meeting the predetermined condition; wherein the terminal performs joint channel estimation based on the configuration information in the process of the uplink channel transmission.
[0212] The network device can schedule uplink channel transmission of the terminal when the terminal meets a predetermined condition. The predetermined condition is a condition required for joint channel estimation of the terminal. The terminal performs uplink transmission based on the scheduling of the network device, and can perform joint channel estimation based on configuration information provided by the network device during the uplink transmission, thereby improving the accuracy of channel estimation and improving network coverage performance.
[0213] In some embodiments, the predetermined condition includes, but is not limited to, at least one of the following:
[0214] The terminal supports uplink channel transmission across time slots or across repeated transmissions.
[0215] The uplink channel of the terminal is located at a fixed frequency domain position; and
[0216] The terminal uses a precoding mode, a TBS (Transport block size) modulation mode, and a fixed beam.
[0217] That is, the terminal supports performing the above joint channel estimation, and can meet the conditions that the frequency domain position of the uplink channel, the precoding mode, the TBS modulation mode, and the beam are all fixed and unchanged, thereby facilitating the above joint channel estimation.
[0218] In some embodiments, the configuration information for the terminal to perform joint channel estimation includes:
[0219] The second dedicated information explicitly carrying the configuration information is issued; wherein the second dedicated information includes configuration information carried in a dedicated information field of predetermined signaling or configuration information carried in dedicated signaling; or
[0220] The second predetermined information implicitly carrying the configuration information is issued.
[0221] In the embodiments of the present disclosure, the above configuration information can be issued to the terminal in a display indication manner. For example, the configuration information is carried in newly added dedicated signaling and issued to the terminal, or a dedicated information field is added in the existing predetermined signaling to carry the above configuration information and issued to the terminal.
[0222] In addition, the configuration information can also be issued in an implicit indication manner, for example, the configuration information is implicitly indicated by a TDRA (Time Domain Resource Assignment) index, or the configuration information is implicitly indicated by a retransmission number, or the configuration information is implicitly indicated by a PUCCH resource. That is, the content, format, quantity, and the like of the parameter having variability in the existing information are associated with the content to be provided by the configuration information and are sent to the terminal. In this way, the terminal can determine the configuration information provided by the network device by receiving the information according to a predetermined rule. In this way, no additional signaling overhead is required, and no new format of the existing signaling needs to be added, and the application range is wider.
[0223] The embodiments of the present disclosure also provide the following examples:
[0224] In the embodiments of the present disclosure, the configuration of the threshold or default condition for supporting joint channel estimation or DMRS bundling is as follows:
[0225] 1. The phase and power limits supporting joint channel estimation or DMRS bundling can be specified by a protocol. For example, the maximum and minimum values of the phase and the maximum and minimum values of the power in a certain time range are specified; the maximum absolute value of the relative deviation of the phase fluctuation or the power fluctuation in a certain time range is specified; and the maximum value of the variance (or standard deviation) of the phase fluctuation or the power fluctuation in a certain time range is specified.
[0226] 2. The terminal can report its own capability or auxiliary information. That is, the terminal can report the support of its own power consistency and phase continuity.
[0227] For example, the terminal can report its power consistency and phase continuity information as its own capability; or report its power consistency and phase continuity information as auxiliary information, and explicitly report the information through physical layer or high layer dedicated information; or report its power consistency and phase continuity information as auxiliary information, and implicitly report the information by using existing information.
[0228] 3. The scheduling of the base station can meet the following conditions:
[0229] The base station and the terminal support cross-repetition transmission or cross-slot uplink transmission in a back-to-back manner, such as PUCCH or PUSCH;
[0230] The frequency domain positions are the same, and no frequency hopping occurs between slots or within a slot.
[0231] The terminal uses the same precoding, transport block size (TBS), modulation, and beam.
[0232] In this disclosure, the triggering mechanism and configuration principles for supporting joint channel estimation or DMRS binding are as follows:
[0233] Base stations can be triggered or configured individually for a single terminal, or they can be jointly triggered or configured for multiple terminals (such as all terminals within a group or all terminals within a cell). When joint triggering is performed, all triggered terminals meet and can report the power consistency and phase continuity information supported by the terminals.
[0234] Furthermore, base stations can configure one or more sets of configuration information for the same terminal, and the granularity of the configuration can be configured based on different situations of the following information:
[0235] 1. For different SCS configurations;
[0236] 2. Configuration for different PUCCH formats;
[0237] 3. Configure for different business types;
[0238] 4. Configure different retransmission counts;
[0239] 5. Different configurations are used for initial transmission and retransmission;
[0240] 6. Configure based on different frequency hopping patterns or DMRS patterns;
[0241] 7. Reporting capabilities based on different terminals.
[0242] For the same terminal, N sets of joint channel estimation configuration information can be maintained, including the duration and time range information of DMRS binding. At any given time, a single terminal can simultaneously activate M sets of configuration information, where M ≤ N. The base station can send the above N sets of configuration information to the terminal and activate M of them.
