Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a timing relationship determination method, terminal equipment and network equipment. Background Art

[0002] The New Radio (NR) system is currently designed for terrestrial communication systems. With the rapid development of mobile Internet, people's demand for Internet access anytime and anywhere is becoming stronger and stronger. The integration of satellite communication systems and NR systems can build a comprehensive communication network that integrates the earth and the sky, meeting the various business needs of user devices everywhere.

[0003] In satellite communication systems or ground-to-air communication systems, ground-to-air communication and satellite communication have a wider coverage, and the transmission delay between terminal equipment and network equipment is much longer than that of terrestrial communication. In particular, in the scenario of satellite communication systems, the transmission delay between terminal equipment and network equipment may be as high as more than one hundred milliseconds. Due to the large air propagation delay between network equipment and terminal equipment in ground-to-air communication or satellite communication systems, a large propagation delay is required from the time when the network equipment sends downlink information to the time when the downlink information reaches the terminal equipment. And in order to meet the uplink synchronization requirements, the uplink advance amount of the terminal equipment to send information needs to be large. Assuming that the time difference between the downlink information in time slot n and the associated uplink transmission in the terrestrial communication system is k time slots, then in the satellite communication system, the time from the network equipment transmitting the downlink information to the terminal equipment receiving the downlink information may be longer than the time of k time slots. In order to meet the uplink synchronization requirements, the terminal equipment needs a certain timing advance amount for the uplink transmission of time slot n+k, and the timing advance amount may also be longer than the time of k time slots. In this way, the timing difference range between the downlink information and the uplink transmission associated with it in the existing system cannot meet the requirements. If the uplink transmission associated with the downlink transmission of time slot Slot#n in the terrestrial communication system is located in time slot n+k, then the uplink transmission associated with the downlink transmission of time slot n in the satellite communication system needs to be located in time slot n+k+k. offset , k+k offset The value of is not less than twice the transmission delay between the network device and the terminal device and the length of time the terminal device processes the downlink data to meet the uplink transmission requirements. The time difference between the downlink transmission and the associated uplink transmission requires an additional offset value k based on the terrestrial communication system. offset .

[0004] If the time difference k+k between the downlink transmission and the associated uplink transmission is indicated in the scheduling information of the uplink transmission offset , the indication information burden of the network device will be very large. If the time difference is indicated in the scheduling information, the signaling overhead will be too large, which will lead to poor service quality of the terminal device and low system efficiency.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0033] The timing relationship determination method provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0034] like Figure 1 FIG. 1 is a flow chart of a method for determining a timing relationship according to an embodiment of the present application. The method is applied to a terminal device and includes:

[0035] Step 101, receiving first information;

[0036] In this step, the first information may be downlink transmission information sent by the network device to the terminal device; for example, the first information may be: information carried by a physical downlink control channel (PDCCH), random access response information, information carried by a physical downlink shared channel (PDSCH), a channel state information reference signal (Channel State Information Reference Signal, CSI-RS), etc.

[0037] Step 102: Determine a target time offset value corresponding to the first information from among at least two pre-configured candidate time offset values;

[0038] In this step, pre-configuration may include pre-setting or pre-configuration, etc. Specifically, the at least two candidate time offset values ​​may be pre-defined (pre-set) by a protocol, or obtained by receiving pre-configuration information (pre-configuration).

[0039] This step determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, so that the terminal device can obtain the target time offset value of the first information without the need for the network device to frequently update the timing difference between the associated first information and the second information, and accurately send the second information. On the one hand, the signaling overhead is reduced. On the other hand, if the target time offset value is too large, far exceeding the timing difference requirement between the downlink transmission and the associated uplink transmission, the associated uplink transmission time is late, and the service transmission delay of the terminal device will be too large, affecting the service quality and system efficiency of the terminal device. If the target time offset value is too small, less than the timing difference requirement between the downlink transmission and the associated uplink transmission, the terminal device cannot complete the associated uplink transmission according to the time difference agreed with the downlink transmission, and the invalid uplink transmission also affects the efficiency of the system. The target time offset value determined in this step adapts to the timing requirement between the first information and the second information, and the terminal device meets the service requirements, thereby improving the system efficiency.

[0040] Step 103: Determine the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value.

[0041] Here, it should be noted that if the first information can be downlink transmission information and the second information can be uplink transmission information, the first time unit is an uplink time unit and the second time unit is a downlink time unit. In this case, in this step, the time difference between the first time unit and the second time unit can be the sum of the basic timing value and the target time offset value, that is: the second time unit is the N+1th time unit after the first time unit, where N is the sum of the basic timing and the target time offset value; or, the second time unit is the first uplink time unit that is located after the first time unit and the time difference between the first time unit and the first time unit is not less than the sum of the basic timing value and the target offset value.

[0042] In addition, it should be noted that in the communication system, the downlink time unit is the basic time unit for downlink transmission, and the uplink time unit is the basic time unit for uplink transmission. The lengths of the uplink time unit and the downlink time unit may be equal or unequal. In the embodiment of the present application, the time difference between the first information and the second information is represented by the time difference between the downlink time unit and the uplink time unit. The time difference is the length of several downlink time units, or the length of several uplink time units. The embodiment of the present application does not make a detailed classification of the counting unit of the time difference between the first information and the second information. Here, the lengths of the downlink time unit and the uplink time unit are both the length of 1 standard time slot, and the time difference between the first information and the second information is the length of X standard time slots.

[0043] In the timing relationship determination method of the embodiment of the present application, the terminal device first receives the first information, then determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, and finally determines the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value, and sends the second information on the second time unit. In this way, on the one hand, it avoids the problem of large signaling overhead caused by the movement of the terminal device or the movement of the network device, and the large change in the air propagation delay between the network device and the terminal device. The network device needs to frequently update the time offset value between the first information and the second information. On the other hand, it meets the service requirements of the terminal device and improves the system efficiency.

[0044] Optionally, the second information includes any of the following:

[0045] (A) information of the first information dispatch;

[0046] For example, when the first information is information carried by PDCCH or random access response information, the second information is information carried by PUSCH scheduled by the first information, information carried by a physical random access channel (PRACH), or a channel detection reference signal (Sounding Reference Signal, SRS).

[0047] (B) feedback information of the first information;

[0048] For example, when the first information is PDSCH, the second information is hybrid automatic repeat request acknowledgement (HARQ-ACK) information for the first information.

[0049] (C) Uplink information obtained by first information measurement.

[0050] For example, when the first information is CSI-RS, the second information is CSI measured based on the first information.

[0051] The following specifically describes a method for determining the basic timing value corresponding to the first information:

[0052] Here, it should be noted that the basic timing value corresponding to the first information can be determined in accordance with the time difference (time offset) between the downlink transmission and the associated uplink transmission in the terrestrial communication system, and the determined time difference is the basic timing value of the first information and the second information in the embodiment of the present application. For example, referring to 3gpp TS38.212 V16.3.0, 3gpp TS38.213 V16.3.0, and 3gpp TS38.214 V16.3.0:

[0053] If the first information is information carried by PDCCH, and the second information is information carried by PUSCH scheduled by the first information, the basic timing value can be determined according to the value of the timing value field in the first information; wherein, the PDCCH used to schedule PUSCH has three formats: DCI format 0_0, DCI format_1 and DCI format_2. The uplink transmission associated with the PDCCH in time slot Slot#n is in time slot n+k. The time domain resource allocation indication field of the PDCCH is used to determine that the time difference (basic timing value) between the PDCCH and the PUSCH scheduled by it is k.

[0054] If the first information is PDSCH and the second information is the HARQ-ACK corresponding to the first information, the basic timing value is determined according to the timing value field in the PDCCH that schedules the PDSCH and / or the timing value options configured by the network device; wherein, the PDCCH used to schedule the PDSCH has three formats: DCI format 1_0, DCI format_1 and DCI format_2. The time difference k between the PDSCH and its corresponding HARQ-ACK feedback is indicated by the network device to the terminal device. For the PDSCH scheduled by DCI format 1_0, the options for k are {1, 2, 3, 4, 5, 6, 7, 8}, and the DCI format 1_0 includes a 3-bit physical downlink shared channel-hybrid automatic repeat request_feedback timing indicator (PDSCH-to-HARQ_feedback timing indicator) field used to indicate that k is one of the values ​​in the options. For PDSCH scheduled by DCI format 1_1 / DCI format 1_2, the options of k are configured to the terminal device by the higher layer signaling dl-DataToUL-ACK and dl-DataToUL-ACKForDCIFormat1_2 for DCI format 1_2 respectively. If more than one value is configured, the PDSCH-to-HARQ_feedback timingindicator field is included in DCI format 1_0 / DCI format 1_2 to indicate one of the timing value options.

[0055] If the first information is CSI-RS and the second information is the CSI corresponding to the first information, the CSI reporting time of the terminal device and the sending time of the measurement resource CSI-RS based on which the CSI reporting is based have a preset timing relationship, and the CSI fed back in the CSI reporting time slot slot#n' has a reference CSI-RS located no later than time slot nn. CSI_ref And the downlink time slot closest to time slot n, where, n CSI_ref =4·2 μDL , n CSI_ref =5·2 μDL ,or, Z' is the latency of the terminal device processing CSI-RS, is the number of symbols in a time slot.

[0056] If the first information is information carried by PDCCH, and the second information is SRS scheduled by the first information, then the basic timing value is the trigger offset value of the non-periodic SRS configured by the high-level signaling; specifically, when the network device schedules the terminal device to send the non-periodic SRS, the transmission time slot of the SRS triggered by the DCI in time slot slot#n is μSRS and μPDCCH are orthogonal frequency division multiplex (OFDM) parameter configuration indexes of the bandwidth part (Bandwidth Part, BWP) where SRS and PDCCH are located, respectively, and the value of k is configured by high-level signaling.

[0057] If the first information is information carried by PDCCH, and the second information is information carried by PRACH scheduled by the first information, then the basic timing value is the time difference between the target PRACH sending timing and the first time unit where the first information is located, and the target PRACH sending timing is the first PRACH sending timing whose time difference with the first time unit is less than a preset value.

[0058] Furthermore, the method further comprises:

[0059] At least two preconfigured candidate time offset values ​​are obtained in a first manner, wherein the first manner includes at least one of the following:

[0060] Broadcast signaling;

[0061] A first configuration signaling corresponding to a first beam, wherein the terminal device is within a beam coverage range of the first beam;

[0062] A second configuration signaling corresponding to a first terminal device group, wherein the terminal device is in the first terminal device group;

[0063] The third configuration signaling corresponding to the terminal device.

[0064] That is, the network device can configure the at least two candidate time offset values ​​for the terminal device through any of broadcast signaling, first configuration signaling corresponding to the first beam, second configuration signaling corresponding to the first terminal device group, or third configuration signaling corresponding to the terminal device.

[0065] The configuration through broadcast signaling is specifically: the network device notifies all terminal devices in the cell of the common candidate time offset value through system information.

[0066] The first configuration signaling configuration corresponding to the first beam is specifically: the network device configures a common candidate time offset value for the terminal devices within the coverage area of ​​the first beam in the cell.

[0067] The second configuration signaling configuration corresponding to the first terminal device group is specifically: the network device configures a candidate time offset value common within the preset terminal device group.

[0068] The third configuration signaling configuration corresponding to the terminal device is specifically: the network device configures a unique candidate time offset value for the terminal device.

[0069] It should be noted here that in the embodiments of the present application, the network device can use the above-mentioned configuration methods to configure zero, one or more candidate time offset values ​​for the terminal device, that is, any of the above-mentioned configuration methods can configure one or more candidate time offset values ​​for the terminal device, or no candidate time offset value is configured for the terminal device.

[0070] Optionally, step 103, determining a target time offset value corresponding to the first information from at least two preconfigured candidate time offset values, includes:

[0071] According to the relevant parameters of the first information, determining, among at least two candidate time offset values, a time offset value corresponding to the relevant parameters of the first information as the target time offset value;

[0072] The relevant parameters of the first information include at least one of the following:

[0073] (A) Downlink Control Information (DCI) format corresponding to the first information;

[0074] (B) the information type of the first information;

[0075] During the communication between the terminal device and the network device, the information type of the first information is different, and the requirements for the time offset (timing difference) between the associated second information and the first information are different. Determining the target time offset value through the information type of the first information can make the timing difference between the downlink transmission and the associated uplink transmission meet the requirements, and try not to use too large a target time offset value to avoid excessive service transmission delay of the terminal device.

[0076] (C) the information type of the second information associated with the first information;

[0077] During the communication between the terminal device and the network device, the information type of the second information is different, and the requirements for the timing difference between the associated first information and the second information are different. The target time offset value is determined by the information type of the second information, so that the timing difference between the downlink transmission and the associated uplink transmission can meet the requirements, and try not to use too large a target time offset value to avoid excessive service transmission delay of the terminal device.

[0078] (D) A hybrid automatic repeat request (HARQ) state of the first information, where the HARQ state includes an enabled state or a disabled state.

[0079] The HARQ mechanism is usually used in the New Radio (NR) system to improve the efficiency of data transmission. During uplink and downlink transmission, each cell has a HARQ entity at the (Media Access Control, MAC) layer, and the uplink and downlink are independent. Each HARQ entity contains multiple parallel HARQ processes. If the data receiving direction feeds back the transmission of the HARQ process to the data sending party in a negative response (NACK) state, the data sending party can retransmit the HARQ process data to the data receiving party. If the HARQ process information decoding fails, the data receiving party writes the HARQ process data into the HARQ buffer area, waits for the retransmitted data block of the HARQ process, and combines the data of the retransmitted data block with the data soft information of the HARQ buffer area for decoding.

[0080] As mentioned above, compared with terrestrial communications, ground-to-air communications and satellite communications have a wider coverage. If the HARQ process merging process based on HARQ-ACK feedback is still used in ground-to-air communications and satellite communications, the air propagation delay and the retransmission process of the HARQ process data due to the HARQ-ACK information feedback will greatly extend the delay of the service data transmission. For some service data delay requirements, such a delay is unacceptable. Therefore, in communication systems with long air propagation delays such as ground-to-air communications and satellite communications, it is possible to disable some HARQ process retransmissions based on HARQ-ACK feedback. That is, the network device can schedule the retransmission of the data before receiving or confirming the HARQ-ACK information of the data transmission. On the other hand, considering the reliability of important data such as system configuration information, the system also needs to retain some data retransmission or new data transmission based on HARQ-ACK feedback scheduling.

[0081] When HARQ transmission based on HARQ-ACK feedback information is disabled, HARQ-ACK feedback is used for link adaptation, and the latency requirement is low. On the contrary, when HARQ transmission based on HARQ-ACK feedback information is enabled, HARQ-ACK feedback is used for scheduling decisions, and the latency requirement is high. The preset or preconfigured HARQ enable / disable states of different first information correspond to different target time offset values. For example, the first information of HARQ disabling corresponds to a larger time offset value, and the HARQ-enabled service corresponds to a smaller time offset value, which is beneficial to system resource management and improves system efficiency.

[0082] Optionally, the DCI format corresponding to the first information includes at least two of the following:

[0083] Access response DCI format;

[0084] Fallback DCI format;

[0085] Non-fallback DCI format;

[0086] Group common DCI format.

[0087] Specifically, the access response DCI format includes any of the following:

[0088] Random access response in a four-step random access process;

[0089] Fallback random access response in two-step random access process;

[0090] A successful random access response in the two-step random access procedure.

[0091] Below, various DCI formats are described:

[0092] Referring to 3gpp TS38.212 V16.3.0, 3gpp TS38.213 V16.3.0 and 3gpp TS38.214 V16.3.0, the access response DCI format may include the following two types:

[0093] The first access response DCI format: after the terminal device sends a random access preamble sequence in the four-step random access process, the random access response information received in the second step includes the scheduling indication information of the terminal device message 3. Among them, the random access response information in the four-step random access process is the first information of the embodiment of the present application, and the message 3 is the second information of the embodiment of the present application.

[0094] The second access response DCI format is message B information in the two-step random access process, and message B includes a successful access response in the two-step random access process, and may also include a fallback random access response. The fallback random access response includes uplink scheduling information, which is used to schedule the scheduling indication information of message 3 when the terminal device falls back from message A to message 3 transmission in the two-step random access process. Among them, the fallback random access response information in the two-step random access process is the first information in the embodiment of the present application, and message 3 is the second information in the embodiment of the present application; or, the successful random access response information in the two-step random access process is the first information in the embodiment of the present application, and the HARQ-ACK feedback for the successful access response is the second information in the embodiment of the present application.

[0095] For the fallback DCI format: the fallback DCI format for scheduling PDSCH is DCI format 1_0, and the fallback DCI format for scheduling Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) is DCI format 0_0.

[0096] Among them, the information field of the fallback DCI format is fixed and supports the most basic scheduling. Specifically, for the fallback DCI format for scheduling PUSCH, the PDCCH using the fallback DCI format is the first information in the embodiment of the present application, and the PUSCH scheduled by the PDCCH of the fallback DCI format is the second information; for the fallback DCI format for scheduling PDSCH, the PDSCH scheduled by the PDCCH using the fallback DCI format is the first information in the embodiment of the present application, and the HARQ-ACK corresponding to the PDSCH is the second information.

[0097] For non-fallback DCI formats: the non-fallback DCI formats for scheduling PDSCH are DCI format 1_1 and DCI format 1_2, and the non-fallback DCI formats for scheduling PUSCH are DCI format 0_1 ​​and DCI format 0_2.

[0098] Among them, the length of some information fields of the non-fallback DCI format is flexibly configurable and can support different scheduling scenarios and business requirements. Among them, for the non-fallback DCI format for scheduling PUSCH, the PDCCH using the non-fallback DCI format is the first information in the embodiment of the present application, and the PUSCH scheduled by the PDCCH of the non-fallback DCI format is the second information; for the non-fallback DCI format for scheduling PDSCH, the PDSCH scheduled by the PDCCH using the non-fallback DCI format is the first information in the embodiment of the present application, and the HARQ-ACK corresponding to the PDSCH is the second information in the embodiment of the present application.

[0099] For group common DCI format: Group Common DCI format is used to transmit control information of a group of terminal devices. Group Common DCI format includes DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, etc.

[0100] Among them, the cyclic redundancy check code (CRC) is scrambled with SFI-RNTI, INT-RNTI, TPC-PUCCH-RNTI / TPC-PUSCH-RNTI, and TPC-SRS-RNTI respectively. In this way, DCI format 2_0 is used to indicate the dynamic time slot structure. On the semi-static flexible symbol of the time slot, its transmission direction can be determined by DCI format 2_0 according to the transmission requirements.

[0101] Among them, for the group common DCI format, the PDCCH using DCI format 2_0 is the first information in the embodiment of the present application, and the valid uplink transmission corresponding to the configuration information indicated by the PDCCH is the second information; DCI format 2_3 indicates that a group of terminal devices send a non-periodic channel sounding reference signal (Sounding Reference Signal, SRS) on a specified carrier. The PDCCH using DCI format 2_3 is the first information in the embodiment of the present application, and the non-periodic SRS indicated by the PDCCH is the second information.

[0102] In an embodiment of the present application, at least two candidate time offset values ​​correspond to various DCI formats. The DCI format may be a downlink control information format for scheduling the first information, or a downlink control information format for the first information. For example, the downlink control information format of the first information includes an access response DCI format, a fallback DCI format, a non-fallback DCI format, and a group common DCI format, and the at least two candidate time offset values ​​include four values: V1, V2, V3, and V4, which correspond to the above four DCI formats, respectively. In an embodiment of the present application, the terminal device obtains the first information and at least two candidate time offset values, and then determines the corresponding target candidate time offset value according to the DCI format corresponding to the first information.

[0103] It should be noted that the DCI format of this embodiment is for illustration only. In the embodiment of the present application, the DCI format corresponding to at least two candidate time offset values ​​may be any combination of at least two of the above four DCI formats. The correspondence may be one-to-one or one-to-many, that is, one candidate time offset value corresponds to multiple DCI formats. In the embodiment of the present application, the DCI format corresponding to at least two candidate time offset values ​​is not limited to these DCI formats.

[0104] Here, it should also be noted that, as mentioned above, currently, in systems with large air propagation delays such as satellite communication systems, the air propagation delay between network devices and terminal devices varies greatly due to the movement of terminal devices or satellites. If the target time offset value is frequently updated to adapt to the change of air propagation delay, the overhead of updating the target time offset value will be very large.

[0105] Using the embodiment of the present application, the terminal device is configured with multiple candidate time offset values. Here, the terminal device is configured with two candidate time offset values. and For example. It is a candidate time offset value common to all terminal devices in a cell configured by the network device through broadcast signaling. It is a candidate time offset value that the network device configures to a terminal device. Assume that the DCI format corresponding to the first information is consistent with the candidate time offset value Determine the target candidate time offset value K offset The corresponding relationship satisfies the method shown in Table 1 below:

[0106] Table 1

[0107]

[0108] The value of meets the needs of the terminal device with the largest propagation delay between the cell and the network device. The value of may be greater than the required time offset value. The value of is more suitable for the terminal device to meet the propagation delay requirements between it and the network device. The first information in the initial access phase corresponds to the access response DCI format, and the associated second information is the message 3 of the initial access phase. The time difference between the first information and the second information is OK, though The value exceeds the time offset value requirement of the terminal device's downlink transmission and the associated uplink transmission. The associated uplink transmission time is later, but it ensures the normal access to the cell when the terminal device does not have specific configuration information during the access phase. After the terminal device accesses the cell, obtain the terminal device-specific candidate time offset value When the first information corresponds to a non-fallback DCI format, A timing difference between the first information and the second information is determined. The actual time offset requirement of the terminal device is closer to that of the terminal device, which can ensure system efficiency. However, during the communication between the terminal device and the network device, the terminal device and / or the network device may move. The time offset requirement between the downlink transmission and the associated uplink transmission cannot always be met. For example, the propagation delay between the terminal device and the network device increases, and the network device cannot be updated in time. and If it is too small, the terminal device cannot The time offset agreed with the downlink transmission completes the associated uplink transmission, resulting in invalid uplink scheduling and affecting the efficiency of the system. Usually, data transmission during the process of Radio Resource Control (RRC) reconfiguration or terminal device switching is guaranteed by the fallback DCI format. Correspondingly, it can be ensured that during RRC reconfiguration or terminal device switching, the uplink transmission of the terminal device can be completed normally according to the time offset agreed with the downlink transmission, thereby improving system efficiency.

[0109] Furthermore, the group common DCI format is applicable to a number of terminal devices constituting the terminal device group. Since the propagation delay between each terminal device and the network device in the terminal device group is different, the target time offset value K offset The actual needs are different. The target time offset value as the second information associated with the group common DCI format can ensure that the uplink transmission of each terminal device in the terminal device group can be completed normally according to the time difference agreed with the downlink transmission, thereby improving system efficiency.

[0110] It should be noted that the target time offset value K shown in Table 1 is offset The corresponding relationship between the DCI format corresponding to the first information is the downlink control information format corresponding to the first information to determine the target time offset value K offset As an example, the method of the embodiment of the present application is that the protocol presets or preconfigures the downlink control information format and the target time offset value K offset According to at least two candidate time offset values Different downlink control information formats and target time offset values ​​K can be set. offset The corresponding relationship between them is not limited in the embodiments of the present application.

[0111] Optionally, the information type of the first information includes any of the following:

[0112] (A) Message B in the two-step random access process;

[0113] For example: in the two-step random access process, the terminal device needs to feedback HARQ-ACK information for message B. When the first information is message B in the two-step random access process and the second information is the HARQ-ACK corresponding to message B, the time difference between the first information and the second information needs to meet the timing difference requirements of all terminal devices supporting the two-step random access process in the cell, so it is necessary to use a larger candidate time offset value, such as the candidate time offset value configured at the cell level or the candidate time offset value specific to the beam.

[0114] (B) Medium Access Control Control Element (MACCE);

[0115] Specifically, MAC CE is control information about the MAC layer. If the first information is the PDSCH carrying the MAC CE, the second information is the HARQ-ACK corresponding to the first information. MAC CE information is more important to the terminal device than general service information, and the delay requirement is relatively loose. On the one hand, if a smaller time offset value (time difference backup value) is used, the target time offset value may not always meet the timing difference requirement between the downlink transmission and the associated uplink transmission due to the movement of the terminal device and / or the network device, resulting in the failure of MAC CE information transmission and affecting the system efficiency. On the other hand, since the delay requirement of MAC CE is relatively loose compared to general service information, using a larger time offset value can ensure the effectiveness of MAC CE information transmission on the basis of meeting the MACCE delay requirement, thereby improving system efficiency.

[0116] Similarly, if the first information is RRC configuration information, and the second information is HARQ-ACK corresponding to the first information, RRC configuration information is more important to the terminal device than general service information. In the case where the first information is RRC configuration information, a larger time offset value between the first information and the second information can also ensure the effectiveness of RRC information transmission and improve system efficiency.

[0117] (C) Channel State Information Reference Signal CSI-RS;

[0118] Since the CSI-RS signal supports multiple antenna ports at the same time and can provide multiple functions, when the first information is CSI-RS and the second information is CSI, the time offset requirement is different from that when the first information and the second information are other types of information. Furthermore, according to the different functions of CSI-RS, the requirements for the time offset value between the first information and the second information are different. The target indication value K is determined by the first information type in the embodiment of the present application. offset The method can make the timing difference between CSI-RS and the associated CSI transmission meet the requirements, and try not to use too large a target time offset value to avoid excessive service transmission delay of the terminal device.

[0119] (D)Business priorities.

[0120] In the communication system, services of different priority levels can be divided according to different performance requirements of service transmission. For example, services of different priority levels can be divided according to different transmission delay requirements. Different target indicator values ​​K are preset or preconfigured to correspond to services of different priority levels. offset For example, a service with lower transmission delay requirements corresponds to a larger candidate time offset value, and a service with higher transmission delay requirements corresponds to a smaller candidate time offset value. This is beneficial to system resource management and improves system efficiency.

[0121] Optionally, in this embodiment of the present application, the CSI-RS includes any of the following:

[0122] CSI-RS for obtaining channel state information;

[0123] CSI-RS for beam management;

[0124] CSI-RS for time-frequency tracking;

[0125] CSI-RS for mobility management.

[0126] In other words, the functions of CSI-RS include: obtaining channel state information, beam management, time-frequency tracking, and mobility management. Among them, the CSI-RS used to obtain channel state information is to ensure scheduling, link adaptation, and transmission settings related to multiple-input multiple-output (MIMO); the CSI-RS used for beam management is used to obtain the shaping weight between the terminal device and the network device; the CSI-RS used for mobility management completes the measurement requirements related to the mobility management of the terminal device.

[0127] When the network device configures each CSI-RS resource for the terminal device, it can also configure its corresponding target time offset value K according to the function assumed by the CSI-RS resource. offset , which of at least two candidate time offset values ​​is used. The terminal device is configured with two candidate time offset values and by For example, the target time offset value corresponding to the CSI-RS resource for beam management can be configured as The target time offset value of CSI-RS resources used for other functions is

[0128] Optionally, the information type of the second information associated with the first information includes any of the following:

[0129] Physical uplink shared channel PUSCH;

[0130] Channel state information CSI;

[0131] Physical Random Access Channel PRACH;

[0132] Sounding Reference Signal SRS.

[0133] Wherein, SRS includes any of the following:

[0134] SRS for beam management;

[0135] SRS for codebook transmission;

[0136] SRS for non-codebook transmission;

[0137] SRS for antenna switching.

[0138] That is to say, for SRS, according to different purposes, the network device can configure multiple SRS resource sets for the terminal. The configuration information of each SRS resource set contains a purpose indication, which can be configured for beam management, uplink channel information acquisition of codebook transmission, uplink channel information acquisition of non-codebook transmission, and downlink channel information acquisition based on SRS antenna switching. SRS resource sets with different purposes have different requirements for the time offset between the second information and the first information. The target time offset value K is determined according to the different purposes of the SRS resource set. offset , the time offset between the downlink transmission and the associated uplink transmission can meet the requirements, and try not to use too large a target time offset value, thereby avoiding excessive service transmission delay of the terminal device.

[0139] Further, in step 102, before determining a target time offset value corresponding to the first information among at least two pre-configured candidate time offset values, the method includes:

[0140] A first signaling is received, where the first signaling is used to indicate a candidate time offset value among the at least two candidate time offset values.

[0141] Specifically, in step 102, determining a target time offset value corresponding to the first information from among at least two preconfigured candidate time offset values ​​includes:

[0142] Among at least two pre-configured candidate time offset values, determine the candidate time offset value indicated by the first signaling as the target time offset value.

[0143] As mentioned above, during the communication between the terminal device and the network device, the relative position between the network device and the terminal device may change as the network device moves, the terminal device moves, or the wireless propagation environment changes. Accordingly, the time offset requirement between the first information and the associated second information will also change. The network device can indicate to the terminal device the most suitable target time offset value K among at least two candidate time offset values ​​according to the current time offset requirement between the first information and the second information through the control bit state of the third information carried by the first signaling. offset , ensuring system efficiency and service performance of terminal equipment.

[0144] It should be noted that, in the embodiment of the present application, the third information and the first information may be the same. For example, when the first information is PDCCH and the second information is PUSCH scheduled by the first information, the first information may indicate the target indication value K in addition to indicating the scheduled PUSCH. offset When the first information is PDSCH and the second information is HARQ-ACK corresponding to the first information, the third information is PDCCH that schedules the first information. The third information schedules PDSCH and also indicates the target indication value K offset .

[0145] It should also be noted that in the embodiment of the present application, the third information indicates the target time offset value K offset , can be indicated together with the basic timing value. For example: the first field in the third information is used to indicate the basic timing value, and the second field is used to indicate the target time offset value K offset .

[0146] That is to say, the target time offset value of the embodiment of the present application can be implicitly indicated according to the relevant parameters of the first information, or can be explicitly indicated by the network device.

[0147] Furthermore, the embodiment of the present application also includes: sending second information on the second time unit.

[0148] In the timing relationship determination method of the embodiment of the present application, the terminal device first receives the first information, then determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, and finally determines the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value, and sends the second information on the second time unit. In this way, on the one hand, it avoids the problem of large changes in the air propagation delay between the network device and the terminal device due to the movement of the terminal device or the movement of the network device, and the network device needs to frequently update the time offset value between the first information and the second information, resulting in a large signaling overhead. On the other hand, it meets the service requirements of the terminal device and improves the system efficiency.

[0149] like Figure 2 FIG. 2 is a flow chart of a method for determining a timing relationship according to an embodiment of the present application, which is applied to a network device. The method includes:

[0150] Step 201, sending first information;

[0151] In this step, the first information may be downlink transmission information sent by the network device to the terminal device; for example, the first information may be: information carried by PDCCH, random access response information, information carried by PDSCH, CSI-RS, etc.

[0152] Step 202, determining a target time offset value corresponding to the first information from among at least two pre-configured candidate time offset values;

[0153] In this step, pre-configuration may include pre-setting (protocol and definition) or pre-configuration, etc.

[0154] Step 203: Determine the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value.

[0155] Here, it should be noted that if the first information can be downlink transmission information and the second information can be uplink transmission information, the first time unit is an uplink time unit and the second time unit is a downlink time unit. In this case, in this step, the time difference between the first time unit and the second time unit can be the sum of the basic timing value and the target time offset value, that is: the second time unit is the N+1th time unit after the first time unit, where N is the sum of the basic timing and the target time offset value; or, the second time unit is the first uplink time unit that is located after the first time unit and the time difference between the first time unit and the first time unit is not less than the sum of the basic timing value and the target offset value.

[0156] In addition, it should be noted that in the communication system, the downlink time unit is the basic time unit for downlink transmission, and the uplink time unit is the basic time unit for uplink transmission. The lengths of the uplink time unit and the downlink time unit may be equal or unequal. In the embodiment of the present application, the time difference between the first information and the second information is represented by the time difference between the downlink time unit and the uplink time unit. The time difference is the length of several downlink time units, or the length of several uplink time units. The embodiment of the present application does not make a detailed classification of the counting unit of the time difference between the first information and the second information. Here, the lengths of the downlink time unit and the uplink time unit are both the length of 1 standard time slot, and the time difference between the first information and the second information is the length of X standard time slots.

[0157] In the timing relationship determination method of the embodiment of the present application, the network device first sends the first information, and then determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, and finally determines the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value, and sends the second information on the second time unit, thereby achieving accurate reception of the second information sent by the terminal device on the second time unit. In this way, on the one hand, it avoids the influence of the movement of the terminal device or the movement of the network device, and the large change of the air propagation delay between the network device and the terminal device, and the network device needs to frequently update the time offset value between the first information and the second information, resulting in a large signaling overhead problem. On the other hand, if the target time offset value is too large, it far exceeds the timing difference requirement between the downlink transmission and the associated uplink transmission, and the associated uplink transmission time is late, the service transmission delay of the terminal device will be too large, affecting the service quality and system efficiency of the terminal device. If the target time offset value is too small, smaller than the timing difference between the downlink transmission and the associated uplink transmission, the terminal device cannot complete the associated uplink transmission according to the agreed time difference with the downlink transmission, and the invalid uplink transmission also affects the efficiency of the system. The target time offset value determined in this step adapts to the timing requirement between the first information and the second information, meets the service requirements of the terminal device, and improves the system efficiency.

[0158] Optionally, the second information includes any of the following:

[0159] First information dispatch information;

[0160] For example, when the first information is information carried by the PDCCH or random access response information, the second information is information carried by the PUSCH, information carried by the PRACH, or SRS scheduled by the first information.

[0161] Feedback information of the first information;

[0162] For example, when the first information is PDSCH, the second information is HARQ-ACK for the first information.

[0163] The first information is uplink information obtained by measuring.

[0164] For example, when the first information is CSI-RS, the second information is CSI measured based on the first information.

[0165] The following specifically describes a method for determining the basic timing value corresponding to the first information:

[0166] Here, it should be noted that the basic timing value corresponding to the first information can be determined in accordance with the time difference (time offset) between the downlink transmission and the associated uplink transmission in the terrestrial communication system, that is, the basic timing value of the first information and the second information in the embodiment of the present application. For example, referring to 3gpp TS38.212 V16.3.0, 3gppTS38.213 V16.3.0, and 3gpp TS38.214 V16.3.0:

[0167] If the first information is information carried by PDCCH, and the second information is information carried by PUSCH scheduled by the first information, the basic timing value can be determined according to the value of the timing value field in the first information; wherein, the PDCCH used to schedule PUSCH has three formats: DCI format 0_0, DCI format_1 and DCI format_2. The uplink transmission associated with the PDCCH in time slot Slot#n is in time slot n+k. The time domain resource allocation indication field of the PDCCH is used to determine that the time difference (basic timing value) between the PDCCH and the PUSCH scheduled by it is k.

[0168] If the first information is PDSCH, and the second information is the HARQ-ACK corresponding to the first information, the basic timing value is determined according to the timing value field in the PDCCH that schedules the PDSCH and / or the configured timing value options; wherein, the PDCCH used to schedule the PDSCH has three formats: DCI format 1_0, DCI format_1, and DCI format_2. The time difference k between the PDSCH and its corresponding HARQ-ACK feedback is indicated by the network device to the terminal device. For the PDSCH scheduled by DCI format 1_0, the options for k are {1, 2, 3, 4, 5, 6, 7, 8}, and the DCI format 1_0 includes a 3-bit PDSCH-to-HARQ_feedback timingindicator field to indicate that k is a value in the options. For PDSCH scheduled by DCI format 1_1 / DCI format 1_2, the options of k are configured to the terminal device by the higher layer signaling dl-DataToUL-ACK and dl-DataToUL-ACKForDCIFormat1_2 for DCI format 1_2 respectively. If more than one value is configured, the PDSCH-to-HARQ_feedback timing indicator field is included in DCI format 1_0 / DCI format 1_2 to indicate one of the timing value options.

[0169] If the first information is CSI-RS and the second information is the CSI corresponding to the first information, the CSI reporting time of the terminal device and the sending time of the measurement resource CSI-RS based on which the CSI reporting is based have a preset timing relationship, and the CSI fed back in the CSI reporting time slot slot#n' has a reference CSI-RS located no later than time slot nn. CSI_ref And the downlink time slot closest to time slot n, where, n CSI_ref =4·2 μDL , n CSI_ref =5·2 μDL ,or, Z' is the latency of the terminal device processing CSI-RS, is the number of symbols in a time slot.

[0170] If the first information is information carried by PDCCH, and the second information is SRS scheduled by the first information, then the basic timing value is the trigger offset value of the non-periodic SRS configured by the high-level signaling; specifically, when the network device schedules the terminal device to send the non-periodic SRS, the transmission time slot of the SRS triggered by the DCI in time slot slot#n is μSRS and μPDCCH are the OFDM parameter configuration indexes of the BWP where SRS and PDCCH are located respectively, and the value of k is configured by high-level signaling.

[0171] If the first information is information carried by PDCCH, and the second information is information carried by PRACH scheduled by the first information, then the basic timing value is the time difference between the target PRACH sending timing and the first time unit where the first information is located, and the target PRACH sending timing is the first PRACH sending timing whose time difference with the first time unit is less than a preset value.

[0172] Furthermore, the method further comprises:

[0173] At least two preconfigured candidate time offset values ​​are sent in a first manner, wherein the first manner includes at least one of the following:

[0174] Broadcast signaling;

[0175] first configuration signaling corresponding to the first beam, wherein the terminal device receiving the at least two candidate time offset values ​​is within the beam coverage of the first beam;

[0176] A second configuration signaling corresponding to the first terminal device group, wherein the terminal device is in the first terminal device group;

[0177] The third configuration signaling corresponding to the terminal device.

[0178] That is, the network device can configure the at least two candidate time offset values ​​for the terminal device through any of broadcast signaling, first configuration signaling corresponding to the first beam, second configuration signaling corresponding to the first terminal device group, or third configuration signaling corresponding to the terminal device.

[0179] The configuration through broadcast signaling is specifically: the network device notifies all terminal devices in the cell of the common candidate time offset value through system information.

[0180] The first configuration signaling configuration corresponding to the first beam is specifically: the network device configures a common candidate time offset value for the terminal devices within the coverage area of ​​the first beam in the cell.

[0181] The second configuration signaling configuration corresponding to the first terminal device group is specifically: the network device configures a candidate time offset value common within the preset terminal device group.

[0182] The third configuration signaling configuration corresponding to the terminal device is specifically: the network device configures a unique candidate time offset value for the terminal device.

[0183] It should be noted here that in the embodiments of the present application, the network device can use the above-mentioned configuration methods to configure zero, one or more candidate time offset values ​​for the terminal device, that is, any of the above-mentioned configuration methods can configure one or more candidate time offset values ​​for the terminal device, or no candidate time offset value is configured for the terminal device.

[0184] Optionally, step 203, determining a target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, includes:

[0185] According to the relevant parameters of the first information, determining, among at least two candidate time offset values, a time offset value corresponding to the relevant parameters of the first information as the target time offset value;

[0186] The relevant parameters of the first information include at least one of the following:

[0187] Downlink control information DCI format corresponding to the first information;

[0188] The information type of the first information; wherein, during the communication between the terminal device and the network device, the information type of the first information is different, and the requirements for the time offset (timing difference) between the associated second information and the first information are different. Determining the target time offset value through the information type of the first information can make the timing difference between the downlink transmission and the associated uplink transmission meet the requirements, and try not to use an excessively large target time offset value to avoid excessive service transmission delay of the terminal device.

[0189] The information type of the second information associated with the first information; wherein, during the communication between the terminal device and the network device, the information type of the second information is different, and the requirements for the timing difference between the associated first information and the second information are different. The target time offset value is determined by the information type of the second information, so that the timing difference between the downlink transmission and the associated uplink transmission can meet the requirements, and try not to use an excessively large target time offset value to avoid excessive service transmission delay of the terminal device.

[0190] A hybrid automatic repeat request HARQ state of the first information, where the HARQ state includes an enabled state or a disabled state.

[0191] The HARQ mechanism is usually used in NR systems to improve the efficiency of data transmission. During uplink and downlink transmission, at the MAC layer, each cell has a HARQ entity, which is independent for uplink and downlink. Each HARQ entity contains multiple parallel HARQ processes. If the data receiving direction feeds back a negative response (NACK) state to the data sending party regarding the transmission of the HARQ process, the data sending party can retransmit the HARQ process data to the data receiving party. If the HARQ process information decoding fails, the data receiving party writes the HARQ process data into the HARQ buffer area, waits for the retransmitted data block of the HARQ process, and combines and decodes the data of the retransmitted data block with the data soft information of the HARQ buffer area.

[0192] As mentioned above, compared with terrestrial communications, ground-to-air communications and satellite communications have a wider coverage. If the HARQ process merging process based on HARQ-ACK feedback is still used in ground-to-air communications and satellite communications, the air propagation delay and the retransmission process of the HARQ process data due to the HARQ-ACK information feedback will greatly extend the delay of the service data transmission. For some service data delay requirements, such a delay is unacceptable. Therefore, in communication systems with long air propagation delays such as ground-to-air communications and satellite communications, it is possible to disable some HARQ process retransmissions based on HARQ-ACK feedback. That is, the network device can schedule the retransmission of the data before receiving or confirming the HARQ-ACK information of the data transmission. On the other hand, considering the reliability of important data such as system configuration information, the system also needs to retain some data retransmission or new data transmission based on HARQ-ACK feedback scheduling.

[0193] When HARQ transmission based on HARQ-ACK feedback information is disabled, HARQ-ACK feedback is used for link adaptation, and the latency requirement is low. On the contrary, when HARQ transmission based on HARQ-ACK feedback information is enabled, HARQ-ACK feedback is used for scheduling decisions, and the latency requirement is high. The preset or preconfigured HARQ enable / disable states of different first information correspond to different target time offset values. For example, the first information of HARQ disabling corresponds to a larger time offset value, and the HARQ-enabled service corresponds to a smaller time offset value, which is beneficial to system resource management and improves system efficiency.

[0194] Optionally, the DCI format corresponding to the first information includes at least two of the following:

[0195] Access response DCI format;

[0196] Fallback DCI format;

[0197] Non-fallback DCI format;

[0198] Group common DCI format.

[0199] Specifically, the access response DCI format includes any of the following:

[0200] Random access response in a four-step random access process;

[0201] Fallback random access response in two-step random access process;

[0202] A successful random access response in the two-step random access procedure.

[0203] Below, various DCI formats are described:

[0204] Referring to 3gpp TS38.212 V16.3.0, 3gpp TS38.213 V16.3.0 and 3gpp TS38.214 V16.3.0, the access response DCI format may include the following two types:

[0205] The first access response DCI format: after the terminal device sends a random access preamble sequence in the four-step random access process, the random access response information received in the second step includes the scheduling indication information of the terminal device message 3. Among them, the random access response information in the four-step random access process is the first information of the embodiment of the present application, and the message 3 is the second information of the embodiment of the present application.

[0206] The second access response DCI format is message B information in the two-step random access process, and message B includes a successful access response in the two-step random access process, and may also include a fallback random access response. The fallback random access response includes uplink scheduling information, which is used to schedule the scheduling indication information of message 3 when the terminal device falls back from message A to message 3 transmission in the two-step random access process. Among them, the fallback random access response information in the two-step random access process is the first information in the embodiment of the present application, and message 3 is the second information in the embodiment of the present application; or, the successful random access response information in the two-step random access process is the first information in the embodiment of the present application, and the HARQ-ACK feedback for the successful access response is the second information in the embodiment of the present application.

[0207] For the fallback DCI format: the fallback DCI format for scheduling PDSCH is DCI format 1_0, and the fallback DCI format for scheduling Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) is DCI format 0_0.

[0208] Among them, the information field of the fallback DCI format is fixed and supports the most basic scheduling. Specifically, for the fallback DCI format for scheduling PUSCH, the PDCCH using the fallback DCI format is the first information in the embodiment of the present application, and the PUSCH scheduled by the PDCCH of the fallback DCI format is the second information; for the fallback DCI format for scheduling PDSCH, the PDSCH scheduled by the PDCCH using the fallback DCI format is the first information in the embodiment of the present application, and the HARQ-ACK corresponding to the PDSCH is the second information.

[0209] For non-fallback DCI formats: the non-fallback DCI formats for scheduling PDSCH are DCI format 1_1 and DCI format 1_2, and the non-fallback DCI formats for scheduling PUSCH are DCI format 0_1 ​​and DCI format 0_2.

[0210] Among them, the length of some information fields of the non-fallback DCI format is flexibly configurable and can support different scheduling scenarios and business requirements. Among them, for the non-fallback DCI format for scheduling PUSCH, the PDCCH using the non-fallback DCI format is the first information in the embodiment of the present application, and the PUSCH scheduled by the PDCCH of the non-fallback DCI format is the second information; for the non-fallback DCI format for scheduling PDSCH, the PDSCH scheduled by the PDCCH using the non-fallback DCI format is the first information in the embodiment of the present application, and the HARQ-ACK corresponding to the PDSCH is the second information in the embodiment of the present application.

[0211] For group common DCI format: the group common DCI format is used to transmit control information of a group of terminal devices. The group common DCI format includes DCI format 2_0, DCI format 2_1, DCI format 2_2, DCI format 2_3, etc.

[0212] Among them, the cyclic redundancy check code (CRC) is scrambled with SFI-RNTI, INT-RNTI, TPC-PUCCH-RNTI / TPC-PUSCH-RNTI, and TPC-SRS-RNTI respectively. In this way, DCI format 2_0 is used to indicate the dynamic time slot structure. On the semi-static flexible symbol of the time slot, its transmission direction can be determined through DCI format 2_0 according to the transmission requirements.

[0213] Among them, for the group common DCI format, the PDCCH using DCI format 2_0 is the first information in the embodiment of the present application, and the valid uplink transmission corresponding to the configuration information indicated by the PDCCH is the second information; DCI format 2_3 indicates that a group of terminal devices send a non-periodic channel sounding reference signal (Sounding Reference Signal, SRS) on a specified carrier. The PDCCH using DCI format 2_3 is the first information in the embodiment of the present application, and the non-periodic SRS indicated by the PDCCH is the second information.

[0214] Furthermore, the group-common DCI format is applicable to several terminal devices constituting the terminal device group. Since the propagation delay between each terminal device and the network device in the terminal device group is different, the actual requirements for the target time offset value are different. In the embodiment of the present application, the target time offset value used as the second information associated with the group-common DCI format can meet the requirements of ensuring that the uplink transmission of each terminal device in the terminal device group can be completed normally according to the time difference agreed with the downlink transmission, thereby improving system efficiency.

[0215] In an embodiment of the present application, at least two candidate time offset values ​​correspond to various DCI formats. The DCI format may be a downlink control information format for scheduling the first information, or a downlink control information format for the first information. For example, the downlink control information format of the first information includes an access response DCI format, a fallback DCI format, a non-fallback DCI format, and a group common DCI format, and the at least two candidate time offset values ​​include four values: V1, V2, V3, and V4, which correspond to the above four DCI formats, respectively. In an embodiment of the present application, the terminal device obtains the first information and at least two candidate time offset values, and then determines the corresponding target candidate time offset value according to the DCI format corresponding to the first information.

[0216] It should be noted that the DCI format of this embodiment is for illustration only. In the embodiment of the present application, the DCI format corresponding to at least two candidate time offset values ​​may be any combination of at least two of the above four DCI formats. The correspondence may be one-to-one or one-to-many, that is, one candidate time offset value corresponds to multiple DCI formats. In the embodiment of the present application, the DCI format corresponding to at least two candidate time offset values ​​is not limited to these DCI formats.

[0217] Here, it should also be noted that, as mentioned above, currently, in systems with large air propagation delays such as satellite communication systems, the air propagation delay between network devices and terminal devices varies greatly due to the movement of terminal devices or satellites. If the target time offset value is frequently updated to adapt to the change of air propagation delay, the overhead of updating the target time offset value will be very large.

[0218] Optionally, the information type of the first information includes any of the following:

[0219] (A) Message B in the two-step random access process;

[0220] For example: in the two-step random access process, the terminal device needs to feedback HARQ-ACK information for message B. When the first information is message B in the two-step random access process and the second information is the HARQ-ACK corresponding to message B, the time difference between the first information and the second information needs to meet the timing difference requirements of all terminal devices supporting the two-step random access process in the cell, so it is necessary to use a larger candidate time offset value, such as the candidate time offset value configured at the cell level or the candidate time offset value specific to the beam.

[0221] (B) Media Access Control Element MAC CE;

[0222] Specifically, MAC CE is control information about the MAC layer. If the first information is the PDSCH carrying the MAC CE, the second information is the HARQ-ACK corresponding to the first information. MAC CE information is more important to the terminal device than general service information, and the delay requirement is relatively loose. On the one hand, if a smaller time offset value (time difference backup value) is used, the target time offset value may not always meet the timing difference requirement between the downlink transmission and the associated uplink transmission due to the movement of the terminal device and / or the network device, resulting in the failure of MAC CE information transmission and affecting the system efficiency. On the other hand, since the delay requirement of MAC CE is relatively loose compared to general service information, using a larger time offset value can ensure the effectiveness of MAC CE information transmission on the basis of meeting the MACCE delay requirement, thereby improving system efficiency.

[0223] Similarly, if the first information is RRC configuration information, and the second information is HARQ-ACK corresponding to the first information, RRC configuration information is more important to the terminal device than general service information. In the case where the first information is RRC configuration information, a larger time offset value between the first information and the second information can also ensure the effectiveness of RRC information transmission and improve system efficiency.

[0224] (C) Channel State Information Reference Signal CSI-RS;

[0225] Since the CSI-RS signal supports multiple antenna ports at the same time and can provide multiple functions, when the first information is CSI-RS and the second information is CSI, the time offset requirement is different from that when the first information and the second information are other types of information. Furthermore, according to the different functions of CSI-RS, the requirements for the time offset value between the first information and the second information are different. The target indication value K is determined by the first information type in the embodiment of the present application. offset The method can make the timing difference between CSI-RS and the associated CSI transmission meet the requirements, and try not to use too large a target time offset value to avoid excessive service transmission delay of the terminal device.

[0226] (D)Business priorities.

[0227] In a communication system, services of different priority levels can be divided according to different performance requirements of service transmission, for example, different priority levels can be divided according to different transmission delay requirements. Different target indication values ​​are preset or preconfigured for services of different priority levels, for example, a service with a lower transmission delay requirement corresponds to a larger candidate time offset value, and a service with a higher transmission delay requirement corresponds to a smaller candidate time offset value, which is beneficial to system resource management and improves system efficiency.

[0228] Optionally, in this embodiment of the present application, the CSI-RS includes any of the following:

[0229] CSI-RS for obtaining channel state information;

[0230] CSI-RS for beam management;

[0231] CSI-RS for time-frequency tracking;

[0232] CSI-RS for mobility management.

[0233] In other words, the functions of CSI-RS include: obtaining channel state information, beam management, time-frequency tracking, and mobility management. Among them, the CSI-RS used to obtain channel state information is to ensure scheduling, link adaptation, and MIMO-related transmission settings; the CSI-RS used for beam management is used to obtain the shaping weight between the terminal device and the network device; the CSI-RS used for mobility management completes the measurement requirements related to the mobility management of the terminal device.

[0234] When the network device configures each CSI-RS resource for the terminal device, it can also configure the corresponding target time offset value according to the function of the CSI-RS resource, which of at least two candidate time offset values ​​is used. and by For example, the target time offset value corresponding to the CSI-RS resource for beam management can be configured as The target time offset value of CSI-RS resources used for other functions is

[0235] Optionally, the information type of the second information associated with the first information includes any of the following:

[0236] Physical uplink shared channel PUSCH;

[0237] Channel state information CSI;

[0238] Physical Random Access Channel PRACH;

[0239] Sounding Reference Signal SRS.

[0240] Wherein, SRS includes any of the following:

[0241] SRS for beam management;

[0242] SRS for codebook transmission;

[0243] SRS for non-codebook transmission;

[0244] SRS for antenna switching.

[0245] That is to say, for SRS, according to different purposes, the network equipment can configure multiple SRS resource sets for the terminal. The configuration information of each SRS resource set contains a purpose indication, which can be configured for beam management, uplink channel information acquisition of codebook transmission, uplink channel information acquisition of non-codebook transmission, and downlink channel information acquisition based on SRS antenna switching. SRS resource sets for different purposes have different requirements for the time offset between the second information and the first information. The target time offset value is determined according to the different purposes of the SRS resource set, so that the time offset between the downlink transmission and the associated uplink transmission can meet the requirements, and try not to use too large a target time offset value, thereby avoiding excessive service transmission delay of the terminal device.

[0246] Further, in step 202, before determining a target time offset value corresponding to the first information among at least two pre-configured candidate time offset values, the method includes:

[0247] Sending a first signaling, where the first signaling is used to indicate one of the at least two candidate time offset values;

[0248] Specifically, in step 202, determining a target time offset value corresponding to the first information from among at least two pre-configured candidate time offset values ​​includes:

[0249] Among at least two pre-configured candidate time offset values, determine the candidate time offset value indicated by the first signaling as the target time offset value.

[0250] As mentioned above, during the communication between the terminal device and the network device, the relative position between the network device and the terminal device may change as the network device moves, the terminal device moves, or the wireless propagation environment changes. Accordingly, the time offset requirement between the first information and the associated second information will also change. The network device can indicate the most suitable target time offset value among at least two candidate time offset values ​​to the terminal device through the control bit state of the third information carried by the first signaling according to the current time offset requirement between the first information and the second information, so as to ensure the system efficiency and the service performance of the terminal device.

[0251] It should be noted that in the embodiment of the present application, the third information and the first information may be the same. For example, when the first information is PDCCH and the second information is PUSCH scheduled by the first information, the first information may indicate the target indication value in addition to indicating the scheduled PUSCH. When the first information is PDSCH and the second information is HARQ-ACK corresponding to the first information, the third information is the PDCCH that schedules the first information. The third information schedules the PDSCH and also indicates the target indication value.

[0252] It should also be noted that in the embodiment of the present application, the third information indicates the target time offset value, which can be indicated together with the basic timing value. For example, the first field in the third information is used to indicate the basic timing value, and the second field is used to indicate the target time offset value.

[0253] That is to say, the target time offset value of the embodiment of the present application can be implicitly indicated according to the relevant parameters of the first information, or can be explicitly indicated by the network device.

[0254] Furthermore, the embodiment of the present application also includes: receiving the second information at the second time unit.

[0255] In the timing relationship determination method of the embodiment of the present application, the network device first sends the first information, and then determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, and finally determines the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value, and receives the second information at the second time unit, thereby achieving accurate reception of the second information sent by the terminal device at the second time unit. In this way, on the one hand, it avoids the influence of the movement of the terminal device or the movement of the network device, and the large change of the air propagation delay between the network device and the terminal device, and the network device needs to frequently update the time offset value between the first information and the second information, resulting in a large signaling overhead. On the other hand, it meets the service requirements of the terminal device and improves the system efficiency.

[0259] The second determination module 303 is used to determine the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value.

[0260] In the terminal device of the embodiment of the present application, first, the first receiving module 301 receives the first information, and then the first determining module 302 determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, and then the second determining module 303 determines the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value. Finally, the terminal device sends the second information in the second time unit. In this way, on the one hand, it avoids the influence of the movement of the terminal device or the movement of the network device, and the large change of the air propagation delay between the network device and the terminal device. The network device needs to frequently update the time offset value between the first information and the second information, resulting in a large signaling overhead. On the other hand, it meets the service requirements of the terminal device and improves the system efficiency.

[0315] The second determination module 403 is used to determine the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value.

[0316] In the network device of the embodiment of the present application, first, the first sending module 401 sends the first information, and then the first determining module 402 determines the target time offset value corresponding to the first information from at least two pre-configured candidate time offset values, and then the second determining module 403 determines the second time unit where the second information associated with the first information is located according to the first time unit where the first information is located, the basic timing value corresponding to the first information, and the target time offset value.
