Description

Communication method and device

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a communication method and device.

Background

Non-terrestrial communication networks (non-terrestrial network, NTN) refer to networks that use radio frequency resources on satellite (or unmanned aerial vehicle system (unmanned aircraft system, UAS) platforms, high altitude platforms (high altitude platform station, HAPS) platforms). Compared with a ground cellular network, such as the fifth generation (5G), the NTN network has the characteristics of wide coverage, lower time delay, broad bandwidth and low cost. As the supplement and extension of the ground network, the NTN network can realize wide area seamless coverage which can not be realized by both the wired telephone network and the ground mobile communication network, and effectively solve the problem of Internet access in the area with lack of communication infrastructure. A large number of satellites are arranged in a near-earth orbit, and the round-trip transmission delay of data between the satellites and a ground terminal is greatly reduced to reach a lower delay of tens of milliseconds. The use of high-frequency band, multi-point wave beam and frequency multiplexing technology obviously improves the communication capability of the satellite, reduces the unit broadband cost and can meet the requirement of high information rate service. NTN has significant cost advantages over communication infrastructure such as terrestrial 5G base stations and undersea fiber optic cables. Modern minisatellites are low in research, development and manufacturing cost, and the service life of the in-orbit satellite can be further prolonged by the software definition technology. The NTN network can be used for scenes such as global coverage (such as remote areas, ocean vessels and the like), emergency disaster relief (such as disaster monitoring and emergency communication), everything interconnection, high-speed movement (such as high-speed rail and aircraft) and the like.

Based on the advantages of the NTN, the NTN is fused with the terrestrial cellular network. Since the propagation delay in NTN is much longer than that of the terrestrial network and the satellite is in a high-speed moving state, the timing relationship of uplink synchronization and New Radio (NR) is enhanced in order to improve the reliability of communication.

However, the processing delay of the terminal device is affected by many factors, such as the processing capability of the baseband chip, the power consumption status of the terminal device, the cost of the terminal device, the specific form of the terminal device (mobile phone, wearable device, internet of things device, etc.), and so on. Thus, the processing delays of signals by different terminal devices may be different. Therefore, how to ensure the reliability of communication between different terminal devices has become a technical problem to be solved.

For a better understanding of the embodiments of the present application, the related art of the embodiments of the present application will be described first.

The third generation partnership project (3rd generation partnership project,3GPP) began with release (R) 14 to conduct a satellite-ground fusion study, and the role and advantages of satellites in 5G systems were discussed in technical standards (technical specification, TS) 22.261, the first time 5G was specified to support satellite access.

Based on the research result of R16, the standardization work of 5G new air interface support NTN is developed in R17, and a first version of fusion technical specification is formed. R18 will continue with the NTN enhancement study.

Satellites (or UAS platforms) can be categorized by orbital altitude as follows:

/>

table 1 NTN platform

Propagation delay in terrestrial mobile systems is typically less than 1 millisecond (ms). In contrast, NTNs have much longer propagation delays, varying from a few milliseconds to hundreds of milliseconds, depending on the altitude of the satellite (or UAS platform) and the elevation of the terminal equipment. Propagation delays in NTN may be as shown in table 2:

TABLE 2 propagation delay in NTN

The propagation delay in NTN is much greater than in terrestrial networks and the satellites are in high-speed motion, so that the uplink synchronization must be enhanced. The time advance of the uplink frame corresponding to the same time slot index at the terminal device side relative to the downlink frame, namely the time interval between the uplink frame and the downlink frame corresponding to the same time slot index is called TA, and the calculation formula of TA in NTN can be expressed as follows:

wherein T is _TA Representing TA. N (N) _TA Indicating the value indicated in the TA adjustment command issued by the access network device, N for the physical random Access channel (physical random access channel, PRACH) _TA Is 0.N (N) _TA May be updated by a TA Command (Command) field in message (Msg) 2/MsgB or MACETA Command. N (N) _TA，offset Is a fixed offset.For Round Trip Time (RTT) between the reference point and the satellite, it can be calculated from the common TA parameter in the system message block (system information block, SIB) 19. The uplink and downlink time sequences are aligned at a reference point. / >And calculating the RTT corresponding to the service link according to the ephemeris and the self position for the terminal equipment. Tc is the basic time unit defined in NR, corresponding to the sampling interval when SCS is 480 kHz.

If the network side enables the TA to report through the system message, the terminal equipment can report the terminal equipment-level TA through the MAC CE in the random access stage, namely the aboveThe NTN also supports event-triggered TA reporting, and defines a TA offset (offset) as the difference between the current terminal equipment TA and the TA successfully reported last time, and triggers the TA reporting when the TA offset exceeds a certain threshold. With SCS=15kHz as reference subcarrier interval, the reported TA is the maximum integer of the number of time slots (slots) which is greater than or equal to the corresponding TA value, namely +.>The units are ms, & lt + & gt>Representing an upward rounding.

In addition, since propagation delay in NTN is much larger than that of the terrestrial network, the timing relationship in NR must be enhanced. Introduction of K into R17 _offset To adjust the timing relationship between the uplink transmission and the downlink transmission at the terminal device side, the uplink transmission time slot n can be determined by the downlink receiving time slot x, and the relationship between n and x can be expressed as follows:

n＝x+2 ^μ ·K _offset +K

wherein K is a timing schedule parameter, and the unit is a slot. K (K) _offset Belonging to the scheduling parameters, indicated to the terminal device by the access network device in ms. In the initial access stage of terminal equipment, K _offset Using cell level K _offset I.e. Cell-specific K _offset The TA of the terminal equipment which is larger than or equal to the coverage area edge of the access network equipment is indicated in the SIB 19, and the value range is 0-1023 ms. μ is an index of SCS used by the terminal device. After the initial access of the terminal device, the access network device can indicate different terminal device levels K through MAC CE according to the TA reported by the terminal device, namely the reported TA _offset I.e. differential UE-specific K _offset The terminal device can calculate the terminal device level K according to the following formula _offset Namely UE-specific K _offset ：

UE-specific K _offset ＝Cell-specific K _offset -differential UE-specific K _offset

For example, referring to fig. 4, fig. 4 is a schematic diagram illustrating PUSCH transmission timing scheduled by downlink control information (downlink control information, DCI) according to an embodiment of the present application. Let SCS be 15kHz. As shown in fig. 4, the access network device sends a PDCCH for scheduling uplink transmission to the terminal device in a downlink slot x, where n=x+2 is expected ^μ ·K _offset +K ₂ And receiving the PUSCH from the terminal equipment. Wherein K is ₂ The time interval from receiving PDCCH to sending the PUSCH scheduled by PDCCH is the unit of time slot. The terminal device may receive the PDCCH in the downlink timeslot x, and may send the PUSCH scheduled by the PDCCH in the uplink timeslot n. The access network device may correctly receive the PUSCH from the terminal device in the uplink slot n.

The CSI is channel state information that the terminal device uses to feed back the downlink channel quality to the access network device, so that the access network device can select an appropriate modulation and coding scheme (modulation and coding scheme, MCS) for downlink data transmission, and can reduce a block error rate (BLER) of downlink data transmission, where time-frequency domain resources required during the transmission are scheduled by the access network device. CSI may be reported through PUCCH or PUSCH. The reporting types can be classified as: periodic reporting (reporting through PUCCH), aperiodic reporting (reporting through PUSCH), PUCCH upper semi-static reporting, PUSCH upper semi-static reporting (triggered by DCI). The reporting type of CSI is indicated by a parameter reporting configuration (reportConfig) in an information element (information element, IE) CSI-reporting (Report) configuration (Config).

For DCI triggered PUSCH-carried CSI reporting, K is also required to be introduced in NTN timing relation _offset . Referring to fig. 5, fig. 5 is a schematic diagram of a DCI triggered CSI reporting sequence according to an embodiment of the present disclosure. Let SCS be 15kHz. As shown in fig. 5, the access network device may send a PDCCH carrying DCI to the terminal device in a downlink timeslot x, which is used to trigger the terminal device to report CSI, where uplink timeslot n=x+2 is expected ^μ ·K _offset +K ₂ Received fromCSI-bearing PUSCH from the terminal device. After receiving the DCI carrying the PDCCH in the downlink timeslot x, the terminal device may send the PUSCH carrying the CSI to the access network device in the uplink timeslot n. The access network device may correctly receive the PUSCH from the terminal device in the uplink slot n.

There are two levels of retransmission mechanisms in NR: HARQ mechanisms of the MAC layer and ARQ mechanisms of the radio link control (radio link control, RLC) layer. Retransmission of lost data or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and complemented by the ARQ mechanism of the RLC layer. The HARQ mechanism of the MAC layer can provide fast retransmission and the ARQ mechanism of the RLC layer can provide reliable data retransmission. HARQ uses Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-wait protocol, after the transmitting end transmits a TB, it stops waiting for acknowledgement. The sender stops waiting for acknowledgement after each transmission, which reduces system throughput. Therefore, multiple parallel HARQ processes are used in NR. While one HARQ process is waiting for acknowledgement information, the transmitting end may continue to transmit data using another HARQ process. The HARQ processes together form a HARQ entity that incorporates a stop-and-wait protocol that allows simultaneous continuous transmission of data. HARQ can be classified into downlink HARQ and uplink HARQ. The downlink HARQ is aimed at downlink data transmission, and the uplink HARQ is aimed at uplink data transmission, and the downlink HARQ and the uplink HARQ are mutually independent. HARQ information may be carried on either PUCCH or PUSCH.

In NTN, since the transmission delay is far longer than that of the terrestrial network, the terminal equipment needs to introduce K when transmitting HARQ feedback information _offset . Referring to fig. 6, fig. 6 is a schematic diagram of an HARQ transmission timing disclosed in an embodiment of the present application. Let SCS be 15kHz. As shown in fig. 6, the terminal device receives PDSCH from the access network device in downlink timeslot x, and may receive PDSCH in uplink timeslot n=x+2 ^μ ·K _offset +K ₁ And sending HARQ feedback information corresponding to the PDSCH, namely HARQ-ACK, to the access network equipment. Wherein K is ₁ The time interval from the reception of PDSCH to the transmission of HARQ-ACK corresponding to the PDSCH by the terminal device is a time slot, and may be indicated by a PDSCH-to-HARQ timing indicator in DCI.

TS38.306 defines two processing capabilities of the terminal device: processing type (processing type) 1 and processing type 2. In case the processing capability of the terminal device is processing type 1, the terminal device supports a maximum of two, four or seven unicast PUSCHs or unicast PDSCH that can be processed on each CC from different TBs per slot. In case the processing capability of the terminal device is processing type 2, the terminal device supports the capability of processing at most one, two, four or seven unicast PUSCHs or unicast PDSCH from different TBs on each CC of each time slot of different number of CA serving cells, respectively.

TS38.214 constrains PDSCH processing time for terminal devices: the first uplink symbol of the PUCCH carrying HARQ-ACK cannot be earlier than symbol L ₁ ，L ₁ T after the last symbol of PDSCH _proc，1 T is the next uplink symbol of (2) _proc，1 Can be expressed as follows:

(N ₁ +d _1，1 +d ₂ )(2048+144)·κ2 ^-μ ·T _C +T _ext

Wherein N is _1，0 Equal to 13 or 14, with respect to the position of PDSCH DMRS.

TS38.214 constrains the preparation time of PUSCH of the terminal device: the first uplink symbol of PUSCH cannot be earlier than symbol L ₂ ，L ₂ T after the last symbol of PDCCH for carrying DCI _proc，2 T is the next uplink symbol of (2) _proc，2 Can be expressed as follows:

max((N ₂ +d _2，1 +d ₂ )(2048+144)·κ2 ^-μ ·T _C +T _ext +T _switch ，d _2，2 )

wherein N is ₂ The PUSCH preparation time is expressed in symbols. D if the first symbol of PUSCH contains DMRS only _2，1 Equal to 0, otherwise, d _2，1 Equal to 1. If an uplink handover gap is triggered, T _switch Equal to the duration of the switching gap, otherwise T _switch Equal to 0. D if DCI triggers a bandwidth part (BWP) switch _2，2 Equal to the switching delay, otherwise, d _2，2 Equal to 0. The processing capacities of the terminal devices are different, namely the processing types are different, and the corresponding N is that ₂ May be different. N corresponding to different processing types ₂ The values of (2) may be as shown in tables 5 and 6:

TS38.214 places constraints on CSI computation time for the terminal device. In case of DCI triggering CSI reporting, the first uplink symbol of the PUSCH carrying the CSI report cannot be earlier than symbol Z _ref Nor can it be earlier than the symbol Z' _ref 。Z _ref PDCCH to trigger CSI reportingT after the last symbol of (2) _proc，CSI T is the next uplink symbol of (2) _proc，CSI Can be expressed as follows:

wherein Z is the time interval from the last symbol of the PDCCH received by the terminal equipment to the completion of the PDCCH analysis. Z's' _ref T 'after the last symbol of the CSI measurement resource closest to PDCCH time' _proc，CSI T 'of the next uplink symbol of (a)' _proc，CSI Can be expressed as follows:

(Z′)(2048+144)·κ2 ^-μ ·T _C

wherein Z' is the time interval from the last symbol of the CSI measurement resource nearest to the PDCCH time to the completion of measuring the CSI. The processing capability of the terminal device is different, that is, the processing type is different, and the corresponding values of Z and Z' may be different. The values of Z and Z' corresponding to different processing types may be as shown in tables 7 and 8:

/>

TABLE 7 treatment of Z and Z 'corresponding to type 1'

TABLE 8 treatment of Z and Z 'corresponding to type 2'

Table 7 applies to the case where the following 6 items are all satisfied: 1) There is only one CSI report; 2) The PUSCH is not multiplexed with the HARQ-ACK and the TB; 3) All central processing units (central processing unit, CPU) are idle; 4) Broad band reporting; 5) Up to 4 ports of CSI-RS resources; 6) The codebook is "typeI-singlePanel" and no CSI-RS resource identity (CSI-RS resource indicator, CRI) needs to be reported, or the reporting number (reportquality) is set to "CRI-RI-CQI".

Z in Table 8 ₁ Is applicable to any one of the following 2: 1) The method comprises the steps that the bandwidth is reported, CSI-RS resources are provided for 4 ports at most, a codebook is 'typeI-single Panel' and CRI is not required to be reported, or the reportquality is set to be 'CRI-RI-CQI'; 2) Broadband reporting, reportquality is Set to "ssb-Index-SINR", "cri-SINR", "sb-Index-SINR-Capability [ Set ] ]Index "or" cri-SINR-Capability [ Set ]]Index). Z in Table 8 ₃ Is suitable for: the reportquality is Set to "ssb-Index-RSRP", "cri-RSRP", "sb-Index-RSRP-Capability [ Set ]]Index "or" cri-RSRP-Capability [ Set ]]Index ", wherein X _μ The KB is determined by the capability term "beamRecortTiming" reported by the UE _l Is determined by the capability item "beamSwitchTiming" reported by the UE. Z in Table 8 ₂ And is applicable to other situations besides the above.

K ₁ And N ₁ Relationship between K ₂ And N ₂ The relationship between these can be as shown in fig. 7. The processing delay of CSI may be determined from Z and Z'. Note that the CSI processing delay is not the maximum value of Z or Z ', but the time point determined from the magnitude between Z and Z' and their corresponding starting points is later, as shown in (a) and (b) of fig. 8.

The processing delay of the terminal equipment is affected by many factors, such as the processing capability of a baseband chip, the power consumption condition of the terminal, the cost of the terminal, the specific form of the terminal (mobile phone, wearable equipment, internet of things equipment and the like), and the like. Thus, the processing delays of signals by different terminal devices may be different.

According to the work item descriptions (work item description, WID) of 3gpp R17 and R18, NTN terminals are mainly divided into two categories: a handheld terminal and a VSAT. For a handheld terminal, because of large user quantity and quick updating, an application specific integrated circuit (application specific integrated circuit, ASIC) is generally adopted for a baseband, and the processing capacity of the baseband can meet the requirement of a protocol on the processing time delay of the terminal equipment. For VSAT, the user quantity is relatively small, the price is high, the updating is slow, a chip manufacturer generally does not specially design an ASIC for VSAT equipment, the baseband generally adopts a soft baseband, and the processing capacity of the baseband can not meet the requirement of a protocol on the processing delay of terminal equipment.

The timing of HARQ feedback is exemplified as an example. Referring to fig. 9, fig. 9 is a schematic diagram of VSAT scheduling according to an embodiment of the present application. Let SCS be 15kHz. As shown in fig. 9, the VSAT receives PDSCH from the access network device in downlink slot x, where DCI carried on the PDSCH indicates K ₁ For 1, vsat should be in upstream slot n=x+2 ^μ ·K _offset And +1 transmits HARQ-ACK corresponding to the PDSCH to the access network equipment. However, since the VSAT adopts the soft baseband, the preparation of the HARQ-ACK corresponding to the PDSCH cannot be completed in the time slot n, and the HARQ-ACK corresponding to the PDSCH cannot be fed back in the time slot n, so that the access network device cannot receive the HARQ-ACK from the VSAT in the uplink time slot n, which results in the failure of the scheduling.

Therefore, in the case where the processing capacities of the terminal devices are different, how to ensure the reliability of the communication of the different terminal devices is very important.

Based on the above network architecture, please refer to fig. 10, fig. 10 is a flow chart of a communication method according to an embodiment of the present application. As shown in fig. 10, the communication method may include the following steps.

1001. The first terminal device sends first indication information to the access network device.

Accordingly, the access network device receives the first indication information from the first terminal device.

The processing type of the terminal device may be a first processing type, a second processing type, or a third processing type. It can be seen that there are three types of processing of the terminal devices in total, and the type of processing of each terminal device may be any one of these three types.

The first processing type may indicate that the terminal device is capable of handling one unicast PUSCH or one unicast PDSCH on each CC per slot, i.e. the terminal device is capable of handling at most one unicast PUSCH or one unicast PDSCH on each CC per slot. It can be seen that in case the processing capability of the terminal device is of the first processing type, the number of unicast PUSCH or unicast PDSCH actually processed by the terminal device per CC per slot may be 0 or 1.

The second processing type may indicate that the terminal device is capable of processing a maximum of two, four, or seven unicast PUSCHs or unicast PDSCH from different TBs on each CC per slot. The second processing type is the processing type 1 described above. For example, in case the second processing type indicates that the terminal device is capable of processing at most two unicast PUSCHs or unicast PDSCH from different TBs on each CC per slot, the number of unicast PUSCHs or unicast PDSCH from different TBs actually processed by the terminal device on each CC per slot may be 0, 1 or 2. For example, in case the second processing type indicates that the terminal device is capable of processing at most four unicast PUSCHs or unicast PDSCH from different TBs on each CC per slot, the number of unicast PUSCHs or unicast PDSCH from different TBs actually processed by the terminal device on each CC per slot may be 0, 1, 2, 3 or 4. For example, in case the second processing type indicates that the terminal device is capable of processing a maximum of seven unicast PUSCHs or unicast PDSCH from different TBs on each CC per slot, the number of unicast PUSCHs or unicast PDSCH from different TBs actually processed by the terminal device on each CC per slot may be 0, 1, 2, 3, 4, 5, 6 or 7.

The third processing type may indicate that the terminal device is capable of handling at most one, two, four or seven unicast PUSCHs or unicast PDSCH, respectively, from different TBs on each CC per time slot of different number of CA serving cells. The third processing type is the processing type 2 described above.

After the first terminal device accesses the access network device, i.e. after the random access is successful, the processing capability of the first terminal device can be determined. And under the condition that the processing capacity of the first terminal equipment is of a first processing type, the first terminal equipment needs to report the processing capacity information to the access network equipment, and can send first indication information to the access network equipment. The first indication information may indicate that the processing capability of the first terminal device is of the first processing type. And under the condition that the processing capacity of the first terminal equipment is of the second processing type, the first terminal equipment does not report the processing capacity information to the access network equipment, and at the moment, the access network equipment can default that the processing capacity of the first terminal equipment is of the second processing type. And under the condition that the processing capacity of the first terminal equipment is of a third processing type, the first terminal equipment needs to report the processing capacity information to the access network equipment, and can send fifth indication information to the access network equipment. The fifth indication information may indicate that the processing capability of the first terminal device is of the third processing type.

The first terminal device may determine its own processing capability according to the type or morphology of the first terminal device. For example, in the case that the first terminal device is a handheld terminal or a mobile terminal, the processing capability of the first terminal device may be of the second processing type or of the third processing type; in the case where the first terminal device is a VSAT, the processing capability of the first terminal device may be of the first processing type.

The first terminal device may also determine its own processing capability according to whether the baseband of the first terminal device is in software or hardware. For example, in the case that the baseband of the first terminal device employs an ASIC, the processing capability of the first terminal device may be of the second processing type or the third processing type; in case the baseband of the first terminal device is a soft baseband, the processing capability of the first terminal device may be of the first processing type.

1002. The access network device indicates information to the first terminal device.

Accordingly, the first terminal device receives the second indication information from the access network device.

The second indication information may indicate the first time interval (i.e., K as described above ₁ ). The first time interval is a time interval from the first terminal device receiving the first PDSCH to transmitting HARQ-ACK corresponding to the first PDSCH.

The first time interval may be determined from a third time interval corresponding to the first processing type. After the access network device receives the first indication information, the first time interval may be determined according to a third time interval corresponding to the first processing type. The third time interval is that the first terminal equipment receives the first time intervalThe time interval between the last symbol of a PDSCH and the first symbol of the HARQ-ACK corresponding to the transmission of the first PDSCH, i.e. T _proc，1 . The HARQ-ACK corresponding to the first PDSCH may be understood as an ACK for feeding back the success of the first PDSCH reception. It should be understood that the first PDSCH is a PDSCH received after the first terminal device accesses the access network device, and is a type of PDSCH, not a specific one. Exemplary, the first terminal device receives the first PDSCH from the access network device in the downlink timeslot x, and in the uplink timeslot n=x+2 ^μ ·K _offset +K ₁ The s-th symbol of the slot n can not be earlier than the symbol L, starting to transmit HARQ-ACK corresponding to the first PDSCH to the access network device ₁ Wherein L is ₁ Is defined as T after the last symbol of the first PDSCH _proc，1 Next uplink symbol of (a).

The second indication information may also indicate a second time interval (i.e., K as described above ₂ ). The second time interval is a time interval from the first terminal device receiving the first PDCCH to transmitting the PUSCH scheduled by the first PDCCH.

The second time interval may be according to a fourth time interval corresponding to the first processing type. After the access network device receives the first indication information, the second time interval may be determined according to a fourth time interval corresponding to the first processing type. The fourth time interval is the time interval between the last symbol of the first PDCCH received by the first terminal device and the first symbol of the PUSCH scheduled by the first PDCCH, i.e. T as described above _proc，2 . The PUSCH scheduled by the first PDCCH may be understood as a PUSCH scheduled by DCI carried on the first PDCCH, or may be understood as a PUSCH carrying information scheduled by DCI carried on the first PDCCH. It should be understood that the first PDCCH is a PDCCH for DCI scheduling received after the first terminal device accesses the access network device, and is a type of PDCCH, not a specific certain PDCCH. Exemplary, the first terminal device receives the first PDCCH from the access network device in the downlink timeslot x, and in the uplink timeslot n=x+2 ^μ ·K _offset +K ₂ Starts to send the PUSCH scheduled by the first PDCCH to the access network device, and the s symbol of the slot n cannot be earlier than the symbol L ₂ Wherein L is ₂ Is defined as T after the last symbol of the first PDCCH _proc，2 Next uplink symbol of (a).

The second time interval may also be determined from a fifth time interval and a sixth time interval corresponding to the first processing type. After the access network device receives the first indication information, the second time interval may also be determined according to the fifth time interval and the sixth time interval corresponding to the first processing type. The fifth time interval is the time interval from the last symbol of the second PDCCH received by the first terminal device to the completion of the analysis of the second PDCCH, i.e., T as described above _proc，CSI . The sixth time interval is the time interval from the last symbol of the CSI measurement resource closest to the second PDCCH time to the completion of CSI measurement, i.e., T 'as described above' _proc，CSI . The CSI measurement resource closest to the second PDCCH in time, i.e., the CSI measurement resource closest to the second PDCCH in time domain. It should be understood that the second PDCCH is a PDCCH for triggering CSI reporting, which is received after the first terminal device accesses the access network device, and is a type of PDCCH, not a specific certain PDCCH. Exemplary, the first terminal device receives the second PDCCH from the access network device in the downlink timeslot x, and in the uplink timeslot n=x+2 ^μ ·K _offset +K ₂ Starts to send PUSCH carrying CSI report to access network equipment, and the s symbol of time slot n can not be earlier than symbol Z _ref Nor can it be earlier than the symbol Z' _ref 。Z _ref T after the last symbol of the second PDCCH to trigger CSI reporting _proc，CSI Z 'of the next uplink symbol of (a)' _ref T 'after the last symbol of CSI measurement resource closest to the second PDCCH time' _proc，CSI Next uplink symbol of (a).

The third time interval may be determined according to the third time delay and SCS, DMRS configuration, percentage of peak rate, and RE mapping corresponding to the first terminal device. After the access network device receives the first indication information, a third time interval may be determined according to the third time delay, and SCS, DMRS configuration, a percentage of peak rate, and an RE mapping relationship corresponding to the first terminal device.

The RE mapping relationship corresponding to the first terminal device includes a time priority mapping and a frequency priority mapping. The third time interval is positively correlated with the third time delay, i.e. the larger the third time delay, the larger the third time interval. The third delay is related to the baseband processing time of the first terminal device, the longer the processing time, the longer the third delay. The access network device may determine, according to SCS, DMRS configuration, a percentage of peak rate, and an RE mapping relationship corresponding to the first terminal device, a processing time of the first terminal device on the first PDSCH, that is, a time from when the first terminal device starts to parse the first PDSCH to when the first PDSCH sends HARQ-ACK corresponding to the first PDSCH. The parsing time of the first PDSCH may include a time of demodulating the first PDSCH, a time of decoding the first PDSCH, and the like. Compared with the second processing type and the third processing type, the terminal equipment corresponding to the first processing type adopts soft baseband for processing, has limited processing capacity and longer waiting time (namely third time delay) and processing time of the first PDSCH.

As shown in table 9, the third time interval corresponding to the first processing type is obtained by adding some symbols to match the processing delay of the soft baseband based on the third time interval corresponding to the second processing type, so that the third time interval corresponding to the first processing type is ensured to be greater than or equal to the third time interval corresponding to the second processing type and the third processing type.

After the access network device receives the first indication information, a fourth time interval may be determined according to the fourth time delay and SCS, the percentage of the peak rate, and the RE mapping relationship corresponding to the first terminal device. The fourth delay is the sum of the longest symbol number required from the first terminal device receiving the first PDCCH to starting to analyze the first PDCCH and the longest symbol number required from the end of analyzing the first PDCCH to the beginning of preparing the PUSCH scheduled by the first PDCCH. The fourth time interval is positively correlated with the fourth time delay, i.e. the larger the fourth time delay, the larger the fourth time interval. The fourth delay is related to the baseband processing time of the first terminal device, the longer the processing time, the longer the fourth delay. The access network device may determine, according to SCS, a percentage of a peak rate, and an RE mapping relationship corresponding to the first terminal device, an parsing time of the first terminal device for the first PDCCH, and a generating time of a PUSCH scheduled by the first PDCCH.

Wherein Y0, Y1, Y2, Y3, Y4, Y5 are all greater than or equal to 0, indicating an increment of the fourth time interval corresponding to the first process type relative to the fourth time interval corresponding to the second process type.

As shown in table 10, the fourth time interval corresponding to the first processing type is obtained by adding some symbols to match the processing delay of the soft baseband based on the fourth time interval corresponding to the second processing type, so that the fourth time interval corresponding to the first processing type is ensured to be greater than or equal to the fourth time interval corresponding to the second processing type and the third processing type.

The fifth time interval may be determined according to the fifth time delay and SCS, the percentage of peak rate, and the RE mapping relation corresponding to the first terminal device. After the access network device receives the first indication information, a fifth time interval may be determined according to the fifth time delay and the SCS, the percentage of the peak rate, and the RE mapping relationship corresponding to the first terminal device. The fifth delay is the sum of the longest symbol number required from the first terminal device receiving the second PDCCH to starting to analyze the second PDCCH and the longest symbol number required from the end of analyzing the second PDCCH to the beginning of preparing the PUSCH scheduled by the second PDCCH. The fifth time interval is positively correlated with the fifth delay. The access network device may determine, according to SCS, a percentage of peak rate, and an RE mapping relationship corresponding to the first terminal device, an analysis time of the first terminal device on the second PDCCH, and a generation time of a PUSCH scheduled by the second PDCCH. The fifth time interval is positively correlated with the fifth delay.

The sixth time interval may be determined according to CSI parameters corresponding to the first terminal device, the positions of CSI-RS and the number of antenna ports, the granularity of the frequency domain of CSI, and the number of CSI that can be calculated simultaneously. After the access network device receives the first indication information, the access network device may first root the C corresponding to the first terminal deviceThe SI parameters, the positions of CSI-RS and the number of antenna ports, the frequency domain granularity of CSI and the number of CSI that can be simultaneously calculated determine the sixth time interval. The CSI parameters corresponding to the first terminal device include a channel quality indication (channel quality indicator, CQI), a precoding matrix indication (precoding matrix indicator, PMI), CRI, an SSB resource indication (SS/PBCH Block resource indicator, SSBRI), a Layer Indicator (LI), a Rank Indication (RI), and the like. The CSI-RS position and the antenna port corresponding to the first terminal equipment refer to the time-frequency resource position and the corresponding port of the CSI-RS reference signal. The frequency domain granularity of the CSI corresponding to the first terminal device includes a wideband (wideband) and a subband (subband). The number N of the CSI which corresponds to the first terminal equipment and can be calculated simultaneously _CPU Indicated by the parameter "simultaneousCSI-reportsPerCC", meaning that there is N _CPU The CSI processing units simultaneously process CSI reports.

Compared with the second processing type and the third processing type, the terminal equipment corresponding to the first processing type adopts the soft baseband for processing, has limited processing capacity and longer waiting time (namely fifth time delay), analysis time of the second PDCCH, generation time of the PUSCH scheduled by the second PDCCH and measurement time of the CSI.

The sixth time interval corresponding to the first processing type is greater than or equal to the sixth time interval corresponding to the second processing type and the third processing type, so that the sixth time interval corresponding to the first processing type is not smaller than the maximum value in the sixth time interval corresponding to the second processing type and the third processing type, and the terminal equipment with the processing capacity of the third processing type can be ensured to measure the CSI in enough time. The fifth time interval and the sixth time interval corresponding to the second processing type may refer to table 7, the fifth time interval and the sixth time interval corresponding to the third processing type may refer to table 8, and the fifth time interval and the sixth time interval corresponding to the first processing type may be as shown in table 11:

TABLE 11

As shown in table 11, the fifth time interval and the sixth time interval corresponding to the first processing type are obtained by adding some symbols to match the processing delay of the soft baseband based on the fifth time interval and the sixth time interval corresponding to the second processing type, so that the fifth time interval and the sixth time interval corresponding to the first processing type can be ensured to be greater than or equal to the fifth time interval and the sixth time interval corresponding to the second processing type and the third processing type.

It should be understood that, in the case that the access network device does not receive the processing capability information reported by the first terminal device to the access network device, the access network device may also send second indication information to the first terminal device, where a first time interval indicated by the second indication information is determined according to a third time interval corresponding to the second processing type, and a second time interval indicated by the second indication information is determined according to a fourth time interval corresponding to the second processing type, or a fifth time interval and a sixth time interval corresponding to the second processing type.

Similarly, when the access network device receives the fifth indication information from the first terminal device, the access network device may also send the second indication information to the first terminal device, where the first time interval indicated by the second indication information is determined according to the third time interval corresponding to the third processing type, and the second time interval indicated by the second indication information is determined according to the fourth time interval corresponding to the third processing type, or the fifth time interval and the sixth time interval corresponding to the third processing type.

The access network device determines the first time interval and the second time interval for the terminal devices with different processing capacities in the same manner, but the determined values of the first time interval and the second time interval may be different, so that the first time interval and the second time interval corresponding to the processing capacities of the terminal devices can be configured for the terminal devices with different processing capacities, the situation that the scheduling fails due to different processing capacities of the terminal devices can be avoided, and the reliability of the communication of the terminal devices can be improved.

After receiving the second indication information for indicating the first time interval, the first terminal device may determine, in the case of receiving the first PDSCH from the access network device, a transmission slot of the HARQ-ACK corresponding to the first PDSCH according to the first time interval. For example, the first terminal device may receive the first PDSCH from the access network device in the downlink timeslot x, and may receive the first PDSCH in the uplink timeslot n=x+2 ^μ ·K _offset +K ₁ And sending HARQ feedback information corresponding to the first PDSCH to the access network equipment. K (K) ₁ I.e. a first time interval.

Fig. 11 is a schematic diagram of HARQ transmission timing of a handheld terminal device according to an embodiment of the present application. Fig. 12 is a schematic diagram of a HARQ transmission timing of a VSAT according to an embodiment of the present disclosure. As shown in fig. 11 and 12, VSAT corresponds to K ₁ Is larger than K corresponding to the handheld terminal ₁ 。

1004. And the first terminal equipment determines the sending time slot of the PUSCH scheduled by the first PDCCH according to the second time interval under the condition of receiving the first PDCCH from the access network equipment.

After the first terminal device receives the second indication information for indicating the second time interval, in the case of receiving the first PDCCH from the access network device, the first terminal device may determine that the first PDCCH is scheduled according to the second time interval Transmission slots of PUSCH. For example, the first terminal device receives the first PDCCH from the access network device in the downlink timeslot x, and may receive the first PDCCH in the uplink timeslot n=x+2 ^μ ·K _offset +K ₂ And sending the PUSCH scheduled by the first PDCCH to the access network equipment. K (K) ₂ I.e. the second time interval.

In the initial access process of the first terminal device, the access network device may configure K to the first terminal device ₁ Or K ₂ 。

In one case, during the initial access procedure of the first terminal device, the access network device may send the first configuration information to the first terminal device. Accordingly, the first terminal device may receive the first configuration information from the access network device. The first configuration information may configure a seventh time interval (i.e., K ₁ ) An eighth time interval (i.e., K ₂ ). The seventh time interval is a time interval from the first terminal equipment receiving the second PDSCH to the HARQ-ACK corresponding to the second PDSCH in the initial access process, and the eighth time interval is a time interval from the first terminal equipment receiving the third PDCCH to the PUSCH scheduled by the third PDCCH in the initial access process. It should be understood that the second PDSCH is a PDSCH received by the first terminal device during the initial access procedure, and is a type of PDSCH, not a specific one. The third PDCCH is a PDCCH for DCI scheduling received by the first terminal device in the initial access process, and is a type of PDCCH, not a specific certain PDCCH.

The seventh time interval may be greater than or equal to the first time delay and the eighth time interval may be greater than or equal to the second time delay. The first delay is the longest number of slots required from the reception of PDSCH by the terminal device to the transmission of PUCCH of HARQ-ACK corresponding to PDSCH. The second time delay is the longest time slot number required by the terminal equipment from receiving the PDCCH to analyzing the PDCCH. The terminal device may be the terminal device with the longest processing delay among the terminal devices. For example, in the case where the processing capabilities of the terminal device are only three types, the terminal device herein may be a terminal device whose processing capability is the corresponding terminal device of the first processing type. For example, the terminal device herein may be a VSAT. For example, in the case where the processing capability of the terminal device has three or more types, the terminal device herein may be a terminal device corresponding to a processing type having the longest processing delay among the three or more types of processing capability. For example, in the case that there is a terminal device having a longer processing delay than the VSAT, the terminal device may be another terminal device. I.e. the terminal device here is the terminal device with the longest processing delay.

In the case that the first terminal device receives the second PDSCH from the access network device in the initial access process, the first terminal device may determine, according to the seventh time interval, a transmission time slot of the HARQ-ACK corresponding to the second PDSCH. In the case that the first terminal device receives the third PDCCH from the access network device in the initial access procedure, the first terminal device may determine a transmission slot of the PUSCH scheduled by the third PDCCH according to the eighth time interval.

As shown in fig. 13, n1 is an uplink time slot in the existing protocol in which the terminal device transmits HARQ-ACK in the initial access process, and n is an uplink time slot in the present embodiment in which the terminal device transmits HARQ-ACK in the initial access process. It can be seen that the corresponding K in this embodiment ₁ Greater than the corresponding K in the existing protocol ₁ . In this embodiment, terminal devices with different processing types send HARQ-ACK in the time slot n in the initial access process, so that it can be ensured that the terminal device with the weakest processing capability can also be successfully scheduled, and the situation of scheduling failure caused by different processing capabilities of the terminal device can be avoided, thereby improving the reliability of communication of the terminal device.

In another case, during the initial access procedure of the first terminal device, the access network device may send the second configuration information to the first terminal device. Accordingly, the first terminal device may receive the second configuration information from the access network device. The second configuration information may configure the ninth time interval. The ninth time interval may be greater than or equal to the tenth time interval and The tenth time interval may be greater thanOr TA equal to the terminal equipment positioned at the coverage edge of the access network equipment, wherein TA is the time interval between the uplink frame and the downlink frame corresponding to the same time slot index, the unit is millisecond ms, and X is the maximum time delay in the first time delay and the second time delay. Mu is the index of SCS used by the first terminal equipment, SCS used by the first terminal equipment is 2 ^μ *15kHz，/>Representing an upward rounding. The second configuration information may be carried in a system message, such as SIB19. It can be seen that the ninth time interval is additionally increased by +.>

In the case that the first terminal device receives the third PDSCH from the access network device in the initial access process, the first terminal device may determine, according to the ninth time interval, a transmission time slot of the HARQ-ACK corresponding to the third PDSCH. In the case that the first terminal device receives the fourth PDCCH from the access network device in the initial access procedure, the first terminal device may determine a transmission slot of the PUSCH scheduled by the fourth PDCCH according to the ninth time interval. It should be understood that the third PDSCH is a PDSCH received by the first terminal device during the initial access procedure, and is a type of PDSCH, not a specific one. The fourth PDCCH is a PDCCH for DCI scheduling received by the first terminal device in the initial access process, and is a type of PDCCH, not a specific certain PDCCH.

As shown in fig. 14, a broken line K _offset For the corresponding K of the terminal equipment in the initial access process in the existing protocol _offset Solid line K _offset For the K corresponding to the terminal equipment in the initial access process in the implementation _offset . It can be seen that the corresponding K in this embodiment _offset Greater than the corresponding K in the existing protocol _offset . In this embodiment, terminal devices of different processing types are in time slot n in the initial access processThe HARQ-ACK is sent, so that the terminal equipment with the weakest processing capacity can be ensured to be successfully scheduled, the situation of scheduling failure caused by different processing capacities of the terminal equipment can be avoided, and the communication reliability of the terminal equipment can be improved.

It can be seen that, taking into account the processing capacity of the terminal device, the corresponding K can be determined from the processing capacity of the terminal device _offset The corresponding K can also be determined according to the processing capability of the terminal equipment ₁ (or K) ₂ )。

The first time interval and the seventh time interval may be greater than or equal to 0 and less than or equal to 31 and the sum of the first time delay, and the second time interval and the eighth time interval may be greater than or equal to 0 and less than or equal to 32 and the sum of the second time delay. It can be seen that, with respect to the terminal devices corresponding to the second processing type and the third processing type, the K corresponding to the terminal device corresponding to the first processing type ₁ And K ₂ The value range of (2) is expanded to ensure K ₁ Can be larger than 31 and can ensure K ₂ The value of (2) is larger than 32.

The first, second, seventh, eighth and ninth time intervals are in units of time slots, and the third, fourth, fifth and sixth time intervals are in units of symbols.

The first access network device may report the eleventh time interval to the access network device through MACCE, or may report the eleventh time interval to the access network device through other messages or signaling, which is not limited herein.

In the case where the processing capability of the first terminal device is of the first processing type, the eleventh time interval may be greater than or equal toIn case the processing capability of the first terminal device is of the second processing type or of the third processing type, the eleventh time interval may be +.>It can be seen that the TA reported by the first terminal device when the processing capability of the first terminal device is of the first processing type is greater than the TA reported when the processing capability of the first terminal device is of the second processing type and the third processing type>The TA reported by the terminal equipment corresponding to the first processing type can be ensured to be larger than the TA reported by the terminal equipment corresponding to the second processing type and the third processing type.
