Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and apparatus for determining the processing time parameters of a physical downlink shared channel. Background Technology

[0002] In communication systems, to avoid impacting hybrid automatic repeat request (HARQ), a scheduling limit time for the physical downlink shared channel (PDSCH) is defined. Within this scheduling limit time, terminal devices are not expected to provide HARQ demodulation results for that PDSCH. However, with the introduction of HARQ feedback disabled, accurately determining the PDSCH scheduling limit time has become a pressing issue. Summary of the Invention

[0003] This disclosure provides a method and apparatus for determining the processing time parameters of a Physical Downlink Shared Channel (PDSCH). Based on the feedback status of each HARQ process of a terminal device, the first time parameters required for processing the PDSCH carried by that HARQ process can be determined.

[0004] In a first aspect, embodiments of this disclosure provide a method for determining processing time parameters of a physical downlink shared channel (PDSCH). The method is executed by a terminal device and includes: determining a first time parameter required for processing the PDSCH carried by each Hybrid Automatic Repeat Request (HARQ) process based on the feedback status of each HARQ process.

[0005] In this disclosure, the terminal device determines the first timing parameters required to process the PDSCH carried by each HARQ process based on the HARQ feedback status of that HARQ process. This makes the determined first timing parameters more accurate, thus avoiding both the impact of an excessively short determined processing time on HARQ and the waste of resources due to an excessively long determined processing time.

[0124] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0125] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0126] 1. Physical Downlink Shared Channel (PDSCH)

[0127] PDSCH is used to carry data from the transmission channel.

[0128] 2. Physical downlink control channel (PDCCH)

[0129] The PDCCH channel transmits downlink control information (DCI) related to the physical uplink and downlink shared channels (PUSCH, PDSCH). DCI information includes rescourc block (RB) allocation information, HARQ process identifiers, and other related data. Only when the terminal device correctly decodes the DCI information can it correctly process PDSCH or PUSCH data.

[0130] 3. Hybrid Automatic Repeat Request (HARQ)

[0131] HARQ is a new communication technology based on FEC (Forward Error Correction) and ARQ (Automatic Repeat Request) developed to improve system throughput (efficiency) and data transmission reliability, and to better resist interference and fading.

[0132] 4. HARQ feedback disabled.

[0133] HARQ feedback disabled means that after receiving a PDSCH carried by a certain HARQ process identifier / HARQ process number, the receiver does not need to send a HARQ acknowledgment (ACK) message based on the demodulation result to the sender, or send a HARQ negative acknowledgement (NACK) message.

[0134] 5. HARQ feedback enabled

[0135] HARQ feedback enabled means that after receiving a PDSCH carried by a certain HARQ process identifier / HARQ process number, the receiver needs to send a HARQ acknowledgment (ACK) message or a HARQ negative acknowledgement (NACK) message to the sender based on the demodulation result.

[0136] 6. Bandwidth Part (BWP)

[0137] The bandwidth part (BWP) is a subset of the total bandwidth. It flexibly adjusts the receiving and transmitting bandwidth of the terminal device through bandwidth adaptation in NR, ensuring that the terminal device's receiving and transmitting bandwidth does not need to be as large as the cell's bandwidth. A terminal can only activate one uplink (UL) BWP and one downlink (DL) BWP simultaneously. Each BWP is configured with a subcarrier spacing (SCS), and unless otherwise specified, all signals and channels on that BWP use that SCS.

[0138] 7. Subcarrier spacing (SCS)

[0139] The subcarrier spacing is inversely proportional to the symbol length in orthogonal frequency division multiplexing (OFDM). For example, when the subcarrier spacing is 15 kHz, the symbol length is 1 / 15 kHz = 66.7 microseconds (µs). In New Radio (NR), 2... μ The product of μ and 15kHz represents the size of the subcarrier spacing. For example, if μ = 0, scs = 15kHz; if μ = 2, scs = 60kHz.

[0140] Please see Figure 1, Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown is an example including a network device 11 and a terminal device 12.

[0141] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0142] The network device 11 in this disclosure is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0143] The terminal device 12 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology or device form used in the terminal device.

[0144] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0145] In a communication system, for a HARQ process with HARQ feedback enabled, the terminal device needs to send a HARQ ACK or HARQ NACK based on the demodulation result of the PDSCH after receiving the PDSCH carried by the HARQ process identifier or HARQ process number. Therefore, the terminal device does not want to send a HARQ ACK or HARQ NACK before the PDSCH demodulation is complete and / or the uplink feedback is ready. However, for a HARQ process with HARQ feedback disabled, the terminal device does not need to send a HARQ ACK or HARQ NACK message based on the demodulation result to the network device after receiving the PDSCH carried by the HARQ process identifier / HARQ process number. Therefore, the terminal device does not want to receive another PDSCH carried by the same HARQ process before the current PDSCH is demodulated. The timing of when the terminal device sends back the demodulation result of the PDSCH, or when it receives another PDSCH carried by the same HARQ process, is related to the PDSCH processing time or processing procedure time. The PDSCH processing time is determined by T. proc.1 Decision. Among them, T proc.1 It can be calculated using the following formula 1:

[0146] T proc,1 =(N1+d) 1,1 +d2)(2048+144)·κ2 -μ ·T c +T ext (1)

[0147] N1 is defined in the PDSCH, and its value is related to the μ value of the terminal device. The relationship between μ and the subcarrier spacing satisfies the following formula 2, T ext d represents the additional processing time for the unlicensed band. 1,1 d2 represents the processing time under specific conditions when the PDSCH mapping mode is A or B, d2 represents the processing time when uplink signals of different priorities overlap, and T represents the processing time under specific conditions. C k is the basic time unit in a communication system, and it is defined in Clause 4.1 of the 3GPP standard TS38.214.

[0148] scs = 15 * 2 μ (2)

[0149] Typically, the subcarrier spacing can be chosen from the subcarrier spacing corresponding to the PDCCH, the subcarrier spacing corresponding to the PDSCH, and the subcarrier spacing corresponding to the uplink channel for transmitting HARQ feedback messages, such that T... proc.1The maximum subcarrier interval is selected. Since in a HARQ process with HARQ feedback disabled, the terminal device does not need to send a HARQ ACK message based on the demodulation result or a HARQ NACK message to the network device, meaning that the subcarrier interval corresponding to the uplink channel sending the HARQ feedback message does not need to be considered in a HARQ process with HARQ feedback disabled, the above method for determining Tproc,1 is not applicable to HARQ processes with HARQ feedback disabled. Therefore, this disclosure proposes a method for determining the time parameters for processing the PDSCH carried by the HARQ process based on the feedback state of the HARQ process. This makes the determined processing time parameters more accurate, thus avoiding both the impact of too short a determined processing time on HARQ and the waste of resources due to too long a determined processing time.

[0150] The following section, with reference to the accompanying drawings, provides a detailed description of a method and apparatus for determining the processing time parameters of a physical downlink shared channel provided in this disclosure.

[0151] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for determining the processing time parameters of a physical downlink shared channel according to an embodiment of this disclosure. This method is executed by a terminal device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0152] Step 201: Based on the status feedback from each Hybrid Automatic Repeat Request (HARQ) process, determine the first timing parameters required to process the Physical Downlink Shared Channel (PDSCH) carried by that HARQ process.

[0153] Optionally, the first time parameter can be the aforementioned T. proc,1 .

[0154] In this disclosure, considering that the corresponding candidate subcarrier intervals differ due to the feedback states of different HARQ processes, the first time parameter T required for processing PDSCH carried by different HARQ processes is determined. proc,1When the value is given, the state of HARQ feedback for each HARQ process can be determined first. Then, based on the actual state of HARQ feedback for each HARQ process, the candidate subcarrier intervals corresponding to the PDSCH carried by each HARQ process can be determined. Then, based on the preset mapping relationship between the second time parameter μ and the subcarrier interval, the second time parameter corresponding to each candidate subcarrier interval can be determined. After that, based on the mapping relationship in the mapping relationship table between the second time parameter and the number of symbols, and the symbol length corresponding to each candidate subcarrier interval, the maximum first time parameter corresponding to each second time parameter μ can be determined.

[0155] The mapping relationship between the preset second time parameter and the subcarrier interval can be agreed upon by the protocol or configured by the network device. Its form can be as shown in the above formula (2), or it can be other forms of mapping relationship, which are not limited in this disclosure.

[0156] Optionally, due to the different capabilities of terminal devices, the mapping relationship between the second time parameter and the number of symbols (N1) may be different for terminal devices with different capabilities. In this disclosure, after determining each second time parameter, the terminal device can determine the mapping relationship table between the second time parameter and the number of symbols N1 according to its own capabilities, and then determine the N1 value corresponding to each second time parameter based on the mapping relationship table. Then, based on the mapping relationship between the second time parameter and the number of symbols and the symbol length corresponding to each candidate subcarrier interval, the maximum first time parameter corresponding to each second time parameter is determined.

[0157] Optionally, when a terminal device accesses a network device, it can report its capability information to the network device, so that the network device can determine the mapping relationship between the second time parameter corresponding to the terminal device and the number of symbols N1 based on the capability information of the terminal device.

[0158] When the processing capability of the terminal device is 1 and the processing capability is 2, the mapping relationship between the second time parameter and N1 can be referred to Tables 5.3-1 and 5.3-2 in 3GPP standard TS38.214, which will not be elaborated here.

[0159] For example, for a terminal device with a processing capacity of 1, when the HARQ feedback state of any of its HARQ processes is enabled, the HARQ process corresponds to three candidate SCSs. The terminal device can first determine the three corresponding second time parameters μ according to the mapping relationship between SCSs and second time parameters as shown in formula (2) above. Then, the terminal device can first look up Table 5.3-1 to determine the N1 value (number of symbols) corresponding to the three μs respectively. Then, the terminal device can calculate the time length corresponding to the three candidate SCSs. Wherein, time length = number of symbols * length of each symbol, and length of each symbol = 1 / scs. Then, the terminal device can select the largest time length from the three time lengths, and the corresponding value (number of symbols) is N1. Finally, based on the finally determined N1 and the corresponding second time parameters, the largest first time parameter can be calculated.

[0160] Optionally, the HARQ feedback for the HARQ process can be enabled or not disabled.

[0161] It should be noted that the first-time parameter values ​​for each HARQ process may be the same or different under different HARQ feedback states; similarly, the first-time parameters for different HARQ processes under the same HARQ feedback state may be the same or different. This disclosure does not impose any limitations on this.

[0162] Optionally, different symbol names can be specified for each HARQ process in different HARQ feedback states. For example, HARQ processes with HARQ feedback enabled correspond to N1, and HARQ processes with HARQ feedback disabled correspond to N1'. This invention does not limit this.

[0163] Optionally, for HARQ processes with HARQ feedback enabled, once the terminal device has determined the first time parameter required to process the PDSCH it carries, it can determine the earliest time to feed back the HARQ process based on this first time parameter. This avoids both situations where the determined processing time is too short, resulting in inaccurate HARQ acknowledgment or unacknowledgment messages, and where the determined processing time is too long, wasting channel resources.

[0164] Alternatively, for HARQ processes with HARQ feedback disabled, once the terminal device determines the first time parameter required to process the PDSCH carried by that HARQ process, it can determine the earliest time to receive another PDSCH carried by that HARQ process based on that first time parameter. This avoids both situations where the determined processing time is too short, causing the received PDSCH to affect HARQ demodulation, and where the determined processing time is too long, wasting channel resources.

[0165] In this disclosure, the terminal device determines the first timing parameters required to process the PDSCH carried by each HARQ based on the feedback status of each HARQ. This makes the determined first timing parameters more accurate, thus avoiding both the impact of an excessively short determined processing time on the HARQ and the waste of resources due to an excessively long determined processing time.

[0166] Please see Figure 3 , Figure 3 This is a flowchart illustrating a method for determining the processing time parameters of a physical downlink shared channel according to an embodiment of this disclosure. This method is executed by a terminal device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0167] Step 301: Determine the status of the feedback from any HARQ process.

[0168] Optionally, the terminal device can determine the current HARQ feedback status based on the HARQ process configuration information indicated by the network device. The terminal device can receive HARQ process configuration information via radio resource control (RRC) messages; this disclosure does not limit this method.

[0169] Step 302: In response to the feedback of any HARQ process being enabled, determine the first time parameter required to process the PDSCH carried by any HARQ based on one of the first subcarrier interval corresponding to the physical downlink control channel PDCCH, the second subcarrier interval corresponding to the PDSCH, and the third subcarrier interval corresponding to the uplink physical channel that sends the HARQ feedback.

[0170] Step 303: In response to the feedback of any HARQ process being disabled, determine the first timing parameters required to process the PDSCH carried by any HARQ process based on one of the first subcarrier interval and the second subcarrier interval.

[0171] In this disclosure, when the HARQ feedback of any HARQ process is enabled, after receiving the HARQ identifier or the PDSCH carried by the process number, the terminal device needs to return a HARQ ACK message or a HARQ NACK message to the network device according to the demodulation result of the PDSCH. That is, at this time, there is a third subcarrier interval corresponding to the uplink physical channel that sends the HARQ feedback of the HARQ process. Thus, the terminal device can determine the first subcarrier interval, the second subcarrier interval, and the third subcarrier interval as candidate subcarrier intervals. Then, based on the relationship between the scs and the second time parameter, and the second time parameter corresponding to the processing capability of the terminal device and the number of symbols (N1), the maximum first time parameter corresponding to each candidate subcarrier interval is determined. Then, based on the maximum first time parameter, the earliest time to send the HARQ feedback is determined.

[0172] When the feedback of the HARQ process is disabled, after receiving the HARQ process identifier or the PDSCH carried by the HARQ process number, the terminal device does not need to return a HARQ ACK message or a HARQNACK message based on the demodulation result to the network device. Thus, the terminal device can determine the first subcarrier interval and the second subcarrier interval as candidate subcarrier intervals, and then determine the maximum first time parameter corresponding to each candidate subcarrier interval based on the relationship between the SCS and the second time parameter, and the second time parameter corresponding to the processing capability of the terminal device and the number of symbols (N1).

[0173] The specific process by which the terminal device determines the first time parameters required to process the PDSCH carried by each HARQ process based on the candidate subcarrier intervals corresponding to each HARQ process can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0174] Optionally, if the feedback of any HARQ process is enabled, the terminal device can determine the earliest time to send the feedback of any HARQ process based on the first time parameter required to process the PDSCH carried by that HARQ process.

[0175] Alternatively, if the feedback from any HARQ process is disabled, the terminal device can determine the earliest time to receive another PDSCH carried by any HARQ process based on the first time parameter required to process the PDSCH carried by that HARQ process.

[0176] In this disclosure, when any HARQ process is in a HARQ feedback enabled state, the terminal device can determine the first time parameter required to process the PDSCH carried by the HARQ process based on one of the following: the first subcarrier interval corresponding to the PDCCH, the second subcarrier interval corresponding to the PDSCH, and the third subcarrier interval corresponding to the uplink physical channel transmitting HARQ feedback. Conversely, when the feedback of the HARQ process is disabled, the first time parameter required to process the PDSCH carried by the HARQ process can be determined based on the first and second subcarrier intervals. Therefore, by determining the first time parameter based on different subcarrier intervals when the HARQ process is in different HARQ feedback states, the determined first time parameter is more accurate. This avoids both the impact of an excessively short determined processing time on HARQ and the waste of resources due to an excessively long determined processing time.

[0177] Please see Figure 4 , Figure 4 This is a flowchart illustrating a method for determining the processing time parameters of a physical downlink shared channel according to an embodiment of this disclosure. This method is executed by a terminal device. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0178] Step 401: Determine the status of the feedback from any HARQ process.

[0179] Step 402: In response to any HARQ feedback being enabled, determine the first time parameter required to process the PDSCH based on one of the first subcarrier interval corresponding to the physical downlink control channel PDCCH, the second subcarrier interval corresponding to the PDSCH, and the first preset subcarrier interval.

[0180] Step 403: In response to any HARQ feedback being disabled, determine the first time parameter required to process the PDSCH based on one of the first subcarrier interval, the second subcarrier interval, and the second preset subcarrier interval.

[0181] Optionally, the first preset subcarrier spacing can be any of the following: the subcarrier spacing corresponding to the uplink physical channel for transmitting HARQ feedback, the subcarrier spacing corresponding to the uplink physical channel that can be used to transmit the HARQ feedback, and the subcarrier spacing corresponding to the uplink (UL) bandwidth (BWP) in the active state.

[0182] The uplink physical channel that can be used to send HARQ feedback can be any uplink physical channel corresponding to the terminal device. This channel can be configured to send HARQ feedback when needed.

[0183] In addition, there may be multiple UL BWPs corresponding to the terminal device. In this disclosure, the SCS corresponding to the UL BWP that is currently in an active state corresponding to the terminal device can be determined as the first preset SCS.

[0184] Optionally, the second preset SCS can be any of the following: the subcarrier interval corresponding to the uplink physical channel that can be used to transmit the HARQ feedback, or the subcarrier interval corresponding to the uplink bandwidth portion that is in the active state.

[0185] For example, when determining candidate subcarrier intervals, if the terminal device determines that feedback for any HARQ process is enabled, then the first subcarrier interval corresponding to the PDCCH, the second subcarrier interval corresponding to the PDSCH, and the subcarrier interval of the uplink physical channel used to send HARQ feedback can be determined as candidate subcarrier intervals. Conversely, if the terminal device determines that feedback for any HARQ process is disabled, then the corresponding first subcarrier interval, the second subcarrier interval, and the fifth subcarrier interval corresponding to the uplink physical channel used to send the HARQ feedback can be determined as candidate subcarrier intervals. Then, based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0186] Alternatively, the terminal device can determine the corresponding first subcarrier interval, second subcarrier interval, and subcarrier interval of the uplink physical channel transmitting HARQ feedback as candidate subcarrier intervals when feedback of any HARQ process is enabled; and if feedback of any HARQ process is disabled, then the corresponding first subcarrier interval, second subcarrier interval, and subcarrier interval corresponding to the active uplink bandwidth portion are determined as candidate subcarrier intervals. Then, based on the mapping relationship between subcarrier intervals and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0187] Alternatively, the terminal device can determine the first subcarrier interval, the second subcarrier interval, and the subcarrier interval of the uplink physical channel that can be used to send HARQ feedback as candidate subcarrier intervals, regardless of whether the feedback of the HARQ process is enabled or disabled. Then, based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0188] Alternatively, the terminal device can determine the first subcarrier interval, the second subcarrier interval, and the subcarrier interval corresponding to the active uplink bandwidth portion of the HARQ process as candidate subcarrier intervals, regardless of whether the feedback of the HARQ process is enabled or disabled. Then, based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0189] The process by which the terminal device determines the largest first time parameter based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols (N1), can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0190] Optionally, if the feedback of any HARQ process is enabled, the terminal device can determine the earliest time to send the feedback of any HARQ process based on the first time parameter required to process the PDSCH carried by that HARQ process.

[0191] Alternatively, if the feedback from any HARQ process is disabled, the terminal device can determine the earliest time to receive another PDSCH carried by any HARQ process based on the first time parameter required to process the PDSCH carried by that HARQ process.

[0192] In this disclosure, when the feedback of any HARQ process is enabled, the terminal device can determine the first time parameter required to process the PDSCH carried by that HARQ process based on one of the first subcarrier interval corresponding to the PDCCH, the second subcarrier interval corresponding to the PDSCH, and a first preset subcarrier interval. Conversely, when the feedback of any HARQ process is disabled, the terminal device can determine the first time parameter required to process the PDSCH carried by that HARQ process based on one of the first subcarrier interval, the second subcarrier interval, and a second preset subcarrier interval. Therefore, by determining the first time parameter based on the corresponding candidate subcarrier interval when the HARQ process is in different HARQ feedback states, the determined first time parameter is more accurate. This avoids both the impact of an excessively short determined processing time on HARQ and the waste of resources due to an excessively long determined processing time.

[0193] Please see Figure 5 , Figure 5 This is a flowchart illustrating a method for determining the processing time parameters of a physical downlink shared channel according to an embodiment of this disclosure. This method is executed by a network device. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0194] Step 501: The network device determines the first timing parameters required for the terminal device to process the Physical Downlink Shared Channel (PDSCH) carried by each HARQ process based on the feedback status of each Hybrid Automatic Repeat Request (HARQ) process of the terminal device.

[0195] Optionally, the first time parameter can be the aforementioned T. proc,1 .

[0196] In this disclosure, considering that the corresponding candidate subcarrier spacings differ due to the feedback states of different HARQ processes, the network device determines the first time parameter T required for the terminal device to process PDSCH carried by different HARQ processes. proc,1 When the value is given, the state of HARQ feedback for each HARQ process can be determined first. Then, based on the actual state of HARQ feedback for each HARQ process, the candidate subcarrier intervals corresponding to the PDSCH carried by each HARQ process can be determined. Then, based on the preset mapping relationship between the second time parameter μ and the subcarrier interval, the second time parameter corresponding to each candidate subcarrier interval can be determined. After that, based on the mapping relationship in the mapping relationship table between the second time parameter and the number of symbols, and the symbol length corresponding to each candidate subcarrier interval, the maximum first time parameter corresponding to each second time parameter μ can be determined.

[0197] The mapping relationship between the preset second time parameter and the subcarrier interval can be agreed upon by the protocol or configured by the network device. Its form can be as shown in the above formula (2), or it can be other forms of mapping relationship, which are not limited in this disclosure.

[0198] Optionally, due to the different capabilities of terminal devices, the mapping relationship between the second time parameter and the number of symbols (N1) may be different for terminal devices with different capabilities. In this disclosure, after the network device determines each second time parameter, it can determine the mapping relationship table between the second time parameter and N1 according to the capabilities of the terminal device itself, and then determine the N1 value corresponding to each second time parameter according to the mapping relationship table. Then, based on the mapping relationship between the second time parameter and the number of symbols and the symbol length corresponding to each candidate subcarrier interval, the maximum first time parameter corresponding to each second time parameter is determined.

[0199] Optionally, when a terminal device accesses a network device, it can report its capability information to the network device, so that the network device can determine the mapping relationship between the second time parameter corresponding to the terminal device and N1 based on the capability information of the terminal device.

[0200] When the processing capability of the terminal device is 1 and the processing capability is 2, the mapping relationship between the second time parameter and N1 can be referred to Tables 5.3-1 and 5.3-2 in 3GPP standard TS38.214, which will not be elaborated here.

[0201] For example, for a terminal device with a processing capacity of 1, when the HARQ feedback state of any of its HARQ processes is enabled, the HARQ process corresponds to three candidate SCSs. The network device can first determine the three corresponding second time parameters μ according to the mapping relationship between SCSs and second time parameters as shown in formula (2) above. Then, the terminal device can first look up Table 5.3-1 to determine the N1 value (number of symbols) corresponding to the three μs respectively. Then, the network device can calculate the time length corresponding to the three candidate SCSs. Wherein, time length = number of symbols * length of each symbol, and length of each symbol = 1 / scs. Then, the network device can select the largest time length from the three time lengths, and the corresponding value (number of symbols) is N1. Finally, based on the finally determined N1 and the corresponding second time parameters, the largest first time parameter can be calculated.

[0202] Optionally, the HARQ feedback for the HARQ process can be enabled or not disabled.

[0203] It should be noted that the first-time parameter values ​​for each HARQ process may be the same or different under different HARQ feedback states; similarly, the first-time parameters for different HARQ processes under the same HARQ feedback state may be the same or different. This disclosure does not impose any limitations on this.

[0204] Optionally, different symbol names can be specified for each HARQ process in different HARQ feedback states. For example, HARQ processes with HARQ feedback enabled correspond to N1, and HARQ processes with HARQ feedback disabled correspond to N1'. This invention does not limit this.

[0205] Optionally, for HARQ processes with HARQ feedback enabled, after determining the first time parameters required for the terminal device to process the PDSCH it carries, the network device can determine the earliest time for the terminal device to provide feedback on the HARQ process based on these first time parameters. This avoids both situations where the determined processing time is too short, making it impossible to obtain the feedback message, and where the determined processing time is too long, wasting channel resources.

[0206] Alternatively, for a HARQ process with HARQ feedback disabled, once the network device determines the first time parameter required for the terminal device to process the PDSCH it carries, it can determine the earliest time to send another PDSCH carried by that HARQ process based on that first time parameter. This avoids both situations where the determined processing time is too short, causing the sent PDSCH to affect HARQ demodulation, and where the determined processing time is too long, wasting channel resources.

[0207] In this disclosure, the network device determines the first timing parameters required to process the PDSCH carried by each HARQ based on the feedback status of each HARQ. This makes the determined first timing parameters more accurate, thus avoiding both the impact of an excessively short determined processing time on the HARQ and the waste of resources due to an excessively long determined processing time.

[0208] Please see Figure 6 , Figure 6 This is a flowchart illustrating a method for determining the processing time parameters of a physical downlink shared channel according to an embodiment of this disclosure. This method is executed by a network device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0209] Step 601: Determine the status of feedback from each HARQ process on the terminal device.

[0210] Optionally, the HARQ feedback status of the terminal device can be indicated by the network device. The network device can indicate HARQ process configuration information via radio resource control (RRC) messages, and this disclosure does not limit this.

[0211] Step 602: In response to the feedback of any HARQ process of the terminal device being enabled, determine the first time parameter required by the terminal device to process the PDSCH carried by any HARQ based on one of the first subcarrier interval corresponding to the physical downlink control channel PDCCH, the second subcarrier interval corresponding to the PDSCH, and the third subcarrier interval corresponding to the uplink physical channel that sends the HARQ feedback.

[0212] Step 603: In response to the feedback that any HARQ process is disabled, determine the first timing parameters required for the terminal device to process the PDSCH carried by any HARQ process based on one of the first subcarrier interval and the second subcarrier interval.

[0213] In this disclosure, when the HARQ feedback of any HARQ process is enabled, after receiving the HARQ identifier or the PDSCH carried by the process number, the terminal device needs to return a HARQ ACK message or a HARQ NACK message to the network device according to the demodulation result of the PDSCH. That is, at this time, there is a third subcarrier interval corresponding to the uplink physical channel that sends the HARQ feedback of the HARQ process. Thus, the network device can determine the first subcarrier interval, the second subcarrier interval, and the third subcarrier interval as candidate subcarrier intervals. Then, based on the relationship between the scs and the second time parameter, and the second time parameter corresponding to the processing capability of the terminal device and the number of symbols (N1), the maximum first time parameter corresponding to each candidate subcarrier interval is determined. Then, based on the maximum first time parameter, the earliest time to send the HARQ feedback is determined.

[0214] When the feedback of the HARQ process is disabled, after receiving the HARQ process identifier or the PDSCH carried by the HARQ process number, the terminal device does not need to return a HARQ ACK message or a HARQNACK message based on the demodulation result to the network device. Thus, the network device can determine the first subcarrier interval and the second subcarrier interval as candidate subcarrier intervals, and then determine the maximum first time parameter corresponding to each candidate subcarrier interval based on the relationship between the SCS and the second time parameter, and the second time parameter corresponding to the processing capability of the terminal device and the number of symbols (N1).

[0215] The specific process by which the network device determines the first time parameters required to process the PDSCH carried by each HARQ process based on the candidate subcarrier intervals corresponding to the PDSCH carried by each HARQ process can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0216] Optionally, if the feedback from any HARQ process is enabled, the network device can determine the earliest time to receive the feedback from any HARQ process based on the first time parameter required for the terminal device to process the PDSCH carried by that HARQ process.

[0217] Alternatively, if the feedback from any HARQ process is disabled, the network device can determine the earliest time to send another PDSCH carried by any HARQ process based on the first time parameter required for the terminal device to process the PDSCH carried by that HARQ process.

[0218] In this disclosure, when any HARQ process in the terminal device is in a HARQ feedback enabled state, the network device can determine the first time parameter required for the terminal device to process the PDSCH carried by the HARQ process based on one of the following: the first subcarrier interval corresponding to the PDCCH, the second subcarrier interval corresponding to the PDSCH, and the third subcarrier interval corresponding to the uplink physical channel transmitting the HARQ feedback. Conversely, when the feedback of the HARQ process is disabled, the first time parameter required for the terminal device to process the PDSCH carried by the HARQ process can be determined based on the first and second subcarrier intervals. Therefore, by determining the first time parameter based on different subcarrier intervals when the HARQ process is in different HARQ feedback states, the determined first time parameter is more accurate. This avoids both the impact of an excessively short determined processing time on HARQ and the waste of resources due to an excessively long determined processing time.

[0219] Please see Figure 7 , Figure 7 This is a flowchart illustrating a method for determining the processing time parameters of a physical downlink shared channel according to an embodiment of this disclosure. This method is executed by a network device. Figure 7 As shown, the method may include, but is not limited to, the following steps:

[0220] Step 701: Determine the status of feedback from each HARQ process of the terminal device.

[0221] Step 702: In response to any HARQ feedback of the terminal device being enabled, determine the first time parameter required to process the PDSCH carried by any HARQ based on one of the first subcarrier interval corresponding to the physical downlink control channel PDCCH, the second subcarrier interval corresponding to the PDSCH, and the first preset subcarrier interval.

[0222] Step 703: In response to any HARQ feedback being disabled, determine the first timing parameters required for processing the PDSCH based on one of the first subcarrier interval, the second subcarrier interval, and the second preset subcarrier interval.

[0223] Optionally, the first preset subcarrier spacing can be any of the following: the subcarrier spacing corresponding to the uplink physical channel for transmitting HARQ feedback, the subcarrier spacing corresponding to the uplink physical channel that can be used to transmit the HARQ feedback, and the subcarrier spacing corresponding to the uplink (UL) bandwidth (BWP) in the active state.

[0224] The uplink physical channel that can be used to send HARQ feedback can be any uplink physical channel corresponding to the terminal device. This channel can be configured to send HARQ feedback when needed.

[0225] In addition, there may be multiple UL BWPs corresponding to the terminal device. In this disclosure, the SCS corresponding to the UL BWP that is currently in an active state corresponding to the terminal device can be determined as the first preset SCS.

[0226] Optionally, the second preset SCS can be any of the following: the subcarrier interval corresponding to the uplink physical channel that can be used to transmit the HARQ feedback, or the subcarrier interval corresponding to the uplink bandwidth portion that is in the active state.

[0227] For example, when determining the candidate subcarrier intervals for each HARQ process, if the network device determines that feedback for any HARQ process is enabled, then the first subcarrier interval corresponding to the PDCCH, the second subcarrier interval corresponding to the PDSCH, and the subcarrier interval of the uplink physical channel used to send HARQ feedback can be determined as candidate subcarrier intervals. Conversely, if the network device determines that feedback for any HARQ process is disabled, then the corresponding first subcarrier interval, the second subcarrier interval, and the fifth subcarrier interval corresponding to the uplink physical channel used to send the HARQ feedback can be determined as candidate subcarrier intervals. Then, based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0228] Alternatively, the network device can determine candidate subcarrier intervals by identifying the corresponding first subcarrier interval, second subcarrier interval, and subcarrier interval of the uplink physical channel transmitting HARQ feedback when the feedback of any HARQ process of the terminal device is enabled; conversely, if the feedback of any HARQ process is disabled, the corresponding first subcarrier interval, second subcarrier interval, and subcarrier interval corresponding to the active uplink bandwidth portion are determined as candidate subcarrier intervals. Then, based on the mapping relationship between subcarrier intervals and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0229] Alternatively, the network device can determine the first subcarrier interval, the second subcarrier interval, and the subcarrier interval of the uplink physical channel that can be used to send HARQ feedback as candidate subcarrier intervals, regardless of whether the feedback of the HARQ process of the terminal device is enabled or disabled. Then, based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0230] Alternatively, the network device can determine the first subcarrier interval, the second subcarrier interval, and the subcarrier interval corresponding to the active uplink bandwidth portion of the HARQ process as candidate subcarrier intervals, regardless of whether the feedback from the terminal device's HARQ process is enabled or disabled. Then, based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols, the largest first time parameter is determined.

[0231] The process by which the network device determines the maximum first time parameter based on the mapping relationship between the subcarrier interval and the second time parameter, and between the second time parameter and the number of symbols (N1), can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0232] Optionally, if the feedback from any HARQ process of the terminal device is enabled, the network device can determine the earliest time to receive the feedback from any HARQ process based on the first time parameter required by the terminal device to process the PDSCH carried by that HARQ process.

[0233] Alternatively, if the feedback from any HARQ process of the terminal device is disabled, the network device can determine the earliest time to send another PDSCH carried by any HARQ process based on the first time parameter required by the terminal device to process the PDSCH carried by that HARQ process.

[0234] In this disclosure, when the network device determines that the feedback of any HARQ process of the terminal device is enabled, it can determine the first time parameter required for the terminal device to process the PDSCH carried by that HARQ process based on one of the first subcarrier interval corresponding to the PDCCH, the second subcarrier interval corresponding to the PDSCH, and a first preset subcarrier interval. Conversely, when the feedback of any HARQ process is disabled, the first time parameter required for the terminal device to process the PDSCH carried by that HARQ process can be determined based on one of the first subcarrier interval, the second subcarrier interval, and a second preset subcarrier interval. Therefore, by determining the first time parameter based on the corresponding candidate subcarrier interval when the HARQ process is in different HARQ feedback states, the determined first time parameter is more accurate. This avoids both the impact of an excessively short determined processing time on HARQ and the waste of resources due to an excessively long determined processing time.

[0235] Please see Figure 8 This is a schematic diagram of the structure of a communication device 800 provided in an embodiment of this disclosure. Figure 8 The communication device 800 shown may include a processing module 801.

[0236] It is understandable that the communication device 800 can be a terminal device, a device within a terminal device, or a device that can be used in conjunction with a terminal device.

[0237] The communication device 800 is located on the terminal equipment side, wherein:
