Description

Method, device, medium, terminal device and network device for transmitting PUSCH

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a medium, a terminal device, and a network device for transmitting a PUSCH.

Background

The nr (new radio) system refers to a fifth Generation Mobile communication system (abbreviated as "5G") dominated by the third Generation partnership project (3rd Generation partnership project ("3 GPP"), in which enhanced Mobile Broadband ("eMBB"), large scale Machine communication ("mtc"), and high-reliable low-latency communication ("URLLC") are defined as main application scenarios of 5G.

In Release 16(Release 16) of 3GPP, a Physical Uplink Shared Channel (PUSCH) includes a dynamically scheduled PUSCH and a semi-statically configured PUSCH, and one transmission of the PUSCH may be configured into one or more Nominal Repetition segments (also referred to as "Nominal Repetition", "Nominal PUSCH Repetition", or "Nominal Repetition"), each of which is split into one or more Actual Repetition segments (Actual Repetition, also referred to as "Actual Repetition", "Actual PUSCH Repetition", or "Actual Repetition") when a slot boundary or a semi-statically configured downlink symbol is encountered.

The PUSCH transmission of Release 16 is very flexible, and different segmentation patterns may appear when configuring different transmission time domain resources and corresponding uplink and downlink timeslot ratios.

Parameters for a PUSCH one-time transmission may include a starting symbol number (S), a number of nominally repeated segments (K), and a symbol length (L) of one nominally repeated segment.

As shown in fig. 1, one transmission of PUSCH starts from the 3rd symbol, i.e., S ═ 3; the number of Nominal repeated segments is 2, namely Nominal rep.1 and Nominal rep.2, namely K is 2; the symbol length L of a nominally repeating segment is 6 symbols, i.e., L ═ 6.

Also shown in FIG. 1 are slot boundaries and downlink symbols that segment Nominal Rep.1 and Nominal Rep.2 into four Actual repeating segments, namely Actual Rep.1-1 corresponding to Nominal Rep.1, and Actual Rep.2-1, Actual Rep.2-2, and Actual Rep.2-3 corresponding to Nominal Rep.2.

Regarding a frequency hopping mechanism for PUSCH transmission in Release 16, two schemes of PUSCH Inter-PUSCH-repetition (Inter-PUSCH-repetition) frequency hopping and slot Inter-slot-repetition (Inter-slot-repetition) frequency hopping are currently supported.

The inter-PUSCH-repetition frequency hopping is divided into two cases, namely, nominal-PUSCH-repetition (INPR) frequency hopping and actual-PUSCH-repetition (IAPR) frequency hopping.

However, in the prior art including Release 16, one of the frequency hopping modes between PUSCH repetitions and between timeslot repetitions is still adopted, and a specific application scenario of INPR frequency hopping and IAPR frequency hopping is not set, and such a single frequency hopping mode cannot meet the requirement of the frequency hopping performance gain under different PUSCH transmission patterns.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 2 is a method 100 for transmitting PUSCH according to an embodiment of the present invention, including the following steps S110 and S120.

Step S110 is: determining a frequency hopping type of the PUSCH based on parameters of the PUSCH inter-repetition frequency hopping, wherein the frequency hopping type comprises nominal PUSCH inter-repetition (INPR) frequency hopping and actual PUSCH inter-repetition (IAPR) frequency hopping in the PUSCH inter-repetition frequency hopping.

Specifically, one transmission of PUSCH configures one or more nominally repeated segments, which are segmented based on slot boundaries and/or downlink symbols configured by Radio Resource Control (RRC) signaling to form actual repeated segments. Where the nominal repeated segment may be used for inp hopping and the actual repeated segment may be used for IAPR hopping.

If INPR hopping is employed, the frequency hopping setting is performed for the nominally repeating segment.

And if IAPR frequency hopping is adopted, carrying out frequency hopping setting on the actual repeated segments. The actual repeated segments are formed by dividing the nominal repeated segments, which can cause a loss of diversity performance in frequency if the actual repeated segments are divided very unevenly or too finely. A first preset symbol length (denoted as N) may be set such that, when a symbol length of one of actual repeated segments formed by dividing a nominal repeated segment is less than the first preset symbol length, a hopping frequency of each of the actual repeated segments divided within the nominal repeated segment is equal to a hopping frequency of a first one of the actual repeated segments.

Information of the first preset symbol length may be sent to the terminal device to instruct the terminal device to configure IAPR hopping according to the information.

The information of the first preset symbol length may be configured through RRC signaling, for example, the information is encapsulated in a pusch-Config field or a configurable grant Config field in RRC BWP-uplinkddedicated signaling, and is transmitted to the terminal device. For example, 2 bits juxtaposed to frequency hopping are added to the pusch-Config field or the configuredgontconfig field to indicate the first preset symbol length, and the 2 bits from 00 to 11 respectively indicate that the first preset symbol length is 0 to 3. The information of the first preset symbol length may be transmitted through a Physical Downlink Shared Channel (PDSCH).

The information of the first preset symbol length may be preset at the network device, and the network device encapsulates the information in a pusch-Config field or a configurable grantconfig field in the RRC BWP-uplinkddedicated signaling and transmits the information to the terminal device.

The information of the first preset symbol length may be preset at the terminal device, and the terminal device configures IAPR hopping based on the information preset locally.

The first preset symbol length may be an integer greater than or equal to 2 and not more than 1/2 of a symbol length of a nominally repeating segment.

The parameters of the PUSCH inter-repetition frequency hopping include a symbol length of the nominal repetition segment, a symbol length of the actual repetition segment, a length difference value (i.e., a symbol difference value) between the actual repetition segments, a maximum symbol difference value, and the like.

Fig. 3 shows a diagram of an uplink symbol and a downlink symbol, wherein the uplink symbol may be used for transmitting PUSCH data (for example, a network device configures a time domain resource mapping of a PUSCH through a TDRA table), the downlink symbol may be configured in a semi-static manner (for example, the network device configures through signaling TDD-UL-DL-Config in RRC), and blank symbols (shown as blank boxes) which are not illustrated as the uplink symbol and the downlink symbol are not used for transmitting PUSCH data. In the other figures of the specification, an uplink symbol, a downlink symbol and a blank symbol have the same meaning.

Fig. 3 includes an upper subpicture corresponding to inp frequency hopping and a lower subpicture corresponding to IAPR frequency hopping. In the upper diagram, one transmission of PUSCH includes a first Nominal repetition segment Nominal rep.1 and a second Nominal repetition segment nominalrep.2, i.e., the number of Nominal repetition segments is 2(K ═ 2), and the symbol length of the Nominal repetition is 10(L ═ 10). In the lower diagram, two Nominal repeated segments are divided into four Actual repeated segments by downlink symbols and slot boundaries, wherein Nominal Rep.1 is divided into a first Actual repeated segment Actual Rep.1-1 and a second Actual repeated segment Actual Rep.1-2, and Nominal Rep.2 is divided into a third Actual repeated segment Actual Rep.2-1 and a fourth Actual repeated segment Actual Rep.2-2; the Actual repeated segments have a symbol difference from each other, e.g., the symbol differences between Actual Rep.1 and Actual Rep.2, Actual Rep.3 and Actual Rep.4 are 1, 1 and 1, respectively, the symbol differences between Actual Rep.2 and Actual Rep.3 and Actual Rep.4 are 0 and 2, respectively, and the symbol differences between Actual Rep.3 and Actual Rep.4 are 2, with a maximum symbol difference of 2.

Fig. 4 includes an upper subpicture corresponding to inp frequency hopping and a lower subpicture corresponding to IAPR frequency hopping. In the upper diagram, one transmission of PUSCH includes a first Nominal repetition segment Nominal rep.1 and a second Nominal repetition segment nominalrep.2, i.e., the number of Nominal repetition segments is 2(K ═ 2), and the symbol length of the Nominal repetition is 7(L ═ 7). In the lower diagram, two Nominal repeating segments are divided into four Actual repeating segments by downlink symbol and slot boundaries, wherein Nominal Rep.1 is divided into a first Actual repeating segment Actual Rep.1-1 and a second Actual repeating segment Actual Rep.1-2, and Nominal Rep.2 is divided into a third Actual repeating segment Actual Rep.2-1 and a fourth Actual repeating segment Actual Rep.2-2; the Actual repeated segments have a symbol difference from each other, e.g., the symbol differences between Actual Rep.1 and Actual Rep.2, Actual Rep.3 and Actual Rep.4 are 0, 2 and 1, respectively, the symbol differences between Actual Rep.2 and Actual Rep.3 and Actual Rep.4 are 2 and 1, respectively, and the symbol differences between Actual Rep.3 and Actual Rep.4 are 3, with a maximum symbol difference of 3.

Based on parameters of PUSCH inter-repetition frequency hopping, such as symbol length of the nominal repetition segment, symbol length of the actual repetition segment, symbol difference value between the actual repetition segments, maximum symbol difference value, and the like, distribution conditions of uplink symbols in the nominal repetition segment and the actual repetition segment can be determined, and the distribution conditions can be utilized to improve performance of the terminal device and/or the network device, for example, a frequency hopping type of the PUSCH is determined according to the distribution conditions, so that higher flexibility in frequency hopping selection, better frequency diversity gain and/or transmission performance can be obtained.

In one class of cases, when the symbol length of the nominal repeated segment is long, the nominal repeated segment is divided into two or more actual repeated segments and frequency hopping transmission is performed by IAPR, frequency selective fading (i.e., transmission interference is strong for a certain frequency band or bands and weak for another frequency band or bands) can be effectively overcome, thereby obtaining frequency diversity gain. However, if the symbol length of the nominal repeated segment is short, the symbol length of two or more actual repeated segments obtained by dividing the nominal repeated segment will be shorter, so that the transmission time on the corresponding hopping frequency band is too short, and thus the frequency diversity gain cannot be obtained.

A second preset symbol length may be set, and when the symbol length of the nominally repeated segment is greater than or equal to the second preset symbol length, it may be determined that the hopping type of the PUSCH is IAPR hopping. The second preset symbol length may be an integer greater than or equal to 8.

The information of the hopping type can be represented by 1bit of information bits, and can be set to 0 or 1, for example, 0 corresponds to IAPR hopping, 1 corresponds to INPR hopping, or 0 corresponds to INPR hopping, and 1 corresponds to IAPR hopping.

As shown in fig. 3, the symbol length of the nominally repeated segment is 10, which exceeds a second predetermined symbol length (e.g., 8), so that the IAPR scheme shown in the following figure can be used for frequency hopping.

In another kind of cases, when the maximum symbol difference of each actual repeated segment into which the nominal repeated segment is divided is small, the power spectral density distribution of each frequency hopping band is uniform, and generally, the case that the transmission time is extremely short does not occur, so even if the power spectrum of a certain frequency band is low, the received power of the base station is not very low, thereby avoiding seriously affecting the uplink transmission performance of the terminal device. However, if the maximum symbol difference is large, the transmission time of some or some actual repeated segments is extremely short, and if the power spectrum of the frequency band corresponding to the actual repeated segment is low, the received power of the base station will be very low, thereby seriously affecting the uplink transmission performance of the terminal device.

A preset symbol difference value may be set, and when the maximum symbol difference value between actual repeated segments is less than the preset symbol difference value, it is determined that the hopping type of the PUSCH is IAPR hopping. The preset sign difference value may be an integer greater than or equal to 2.

The information of the hopping type can be represented by 1bit of information bits, which can be set to 0 or 1, for example, 0 corresponds to IAPR hopping, 1 corresponds to INPR hopping, or 0 corresponds to INPR hopping, and 1 corresponds to IAPR hopping.

The two cases may be combined, for example, the information bits may be determined based on a preset symbol length and a preset symbol difference value, wherein the information bits indicate that the hopping type of the PUSCH is INPR hopping when the symbol length of the nominal repeated segment is less than a second preset symbol length and when a maximum symbol difference value between actual repeated segments is greater than or equal to the preset symbol difference value.

Specifically, when the symbol length of the nominal repeated segment is less than the second preset symbol length and when the maximum symbol difference value between the actual repeated segments is greater than or equal to the preset symbol difference value, the symbol length of one or some of the actual repeated segments is short, so that the transmission time on the corresponding frequency hopping band is too short, and thus the frequency diversity gain cannot be obtained, and if the power spectrum of the frequency band corresponding to the actual repeated segment is low, the received power of the base station is very low, and thus the uplink transmission performance of the terminal device is seriously affected. Therefore, the INPR hopping scheme having a longer symbol length than the IAP R hopping scheme is adopted as the hopping type of the terminal device.

As shown in fig. 4, the symbol length of the nominal repetition segment is 7, which is smaller than the second preset symbol length (e.g., 8), and the maximum symbol difference value is 3, which is larger than the preset symbol difference value (e.g., 2), so that the frequency hopping can be performed in the INPR manner shown in the upper sub-figure.

The above two cases may also be combined, for example, the information bit is determined based on a preset symbol length and a preset symbol difference value, wherein the information bit indicates that the hopping type of the PUSCH is IAPR hopping when the symbol length of the nominal repeated segment is greater than or equal to a second preset symbol length and when the maximum symbol difference value between actual repeated segments is less than the preset symbol difference value.

As described above, in some scenarios, the frequency hopping type using inp hopping does not have the corresponding technical advantages of IAPR hopping, but the use of inp hopping can avoid the technical problems that IAPR hopping may bring. For example, the actual repeated segmentation of very short symbol lengths makes the transmission time on the corresponding frequency hopping band too short, so that frequency diversity gain cannot be obtained, but the frequency hopping times and the complexity of equipment design are increased; if the power spectrum of the frequency band corresponding to the actual repeated segment with the short symbol length is lower, the received power of the base station will be very low, and the uplink transmission performance of the terminal device will be seriously affected. Therefore, the INPR hopping frequency can be set as a default hopping frequency type.

Step S120 is: and sending the information of the frequency hopping type to the terminal equipment.

The information of the frequency hopping type may be encapsulated in a pusch-Config field or a configuredGrantConfig field in the RRC BWP-uplinkddedicated signaling. And, the information is transmitted from the network device to the terminal device. Information of the frequency hopping type may be transmitted through the PDSCH.

The 1-bit information bit may be set to the highest bit of frequency hopping in the pusch-Config field or the configuredGrantConfig field, or to 1bit juxtaposed to frequency hopping.

The following is described by way of specific examples.

In the first embodiment, as shown in fig. 5, the starting symbol number is 2(S ═ 2), the number of nominally repeated segments is 2(K ═ 2), and the length of the nominally repeated symbol is 8(L ═ 8).

Two Nominal repeated segments, namely Nominal Rep.1 and Nominal Rep.2, are configured for one transmission of the PUSCH, and Nominal Rep.1 and Nominal Rep.2 are segmented based on a time slot boundary and a downlink symbol configured by RRC signaling to obtain three Actual repeated segments, namely Actual Rep.1-1, Actual Rep.2-1 and Actual Rep.2-2.

The second preset symbol length is set to 8, and since the symbol length (L ═ 8) of Nominal rep.1 and Nominal rep.2 is equal to the second preset symbol length, IAPR scheme can be used for frequency hopping.

In the second embodiment, as shown in fig. 6, the starting symbol has a number of 9(S ═ 9), the number of nominally repeated segments is 1(K ═ 1), and the length of the nominally repeated symbol is 10(L ═ 10).

A Nominal repeated segment, namely Nominal Rep.1, is configured for one transmission of the PUSCH, and the Nominal Rep.1 is segmented based on a time slot boundary and a downlink symbol without RRC signaling configuration to obtain two Actual repeated segments, namely Actual Rep.1-1 and Actual Rep.1-2.

The second preset symbol length is set to 8, and since the symbol length (L ═ 10) of the Nominal rep.1 is greater than the second preset symbol length, IAPR scheme can be used for frequency hopping.

In the third embodiment, as shown in fig. 7, the starting symbol number 2(S ═ 2), the number of nominally repeated segments is 2(K ═ 2), and the length of the nominally repeated symbol is 8(L ═ 8).

Two Nominal repeated segments, namely Nominal Rep.1 and Nominal Rep.2, are configured for one transmission of the PUSCH, and Nominal Rep.1 and Nominal Rep.2 are segmented based on a time slot boundary and a downlink symbol configured by RRC signaling to obtain four Actual repeated segments, namely Actual Rep.1-1, Actual Rep.1-2, Actual Rep.2-1 and Actual Rep.2-2.

The preset symbol difference value is set to 2(N ═ 2), and the Actual rep.1-1, Actual rep.1-2, Actual rep.2-1, and Actual rep.2-2 symbol numbers are respectively 4, 3, 4, the symbol difference value between them is 0 or 1, and the maximum symbol difference value is 1, which is smaller than the preset symbol difference value (N ═ 2), so that frequency hopping can be performed in the IAPR manner.

In the fourth embodiment, as shown in fig. 8, the number of start symbols is 4(S ═ 4), the number of nominally repeated segments is 2(K ═ 2), and the symbol length of the nominal repetition is 7(L ═ 7).

In one aspect, the second preset symbol length is set to 8, and the symbol lengths (L ═ 7) of Nominal rep.1 and Nominal rep.2 are less than the second preset symbol length; on the other hand, the preset symbol difference value is set to 2(N ═ 2), and the actualprep.1-1, actualprep.2-1, and actualprep.2-2 symbol numbers are respectively

Fig. 11 is a flowchart of another method 300 for transmitting PUSCH in an embodiment of the present invention, including the following steps S310, S320, and S330.

Step S310 is: and receiving information of PUSCH frequency hopping types sent by the network equipment, wherein the PUSCH frequency hopping types comprise nominal PUSCH inter-repetition INPR frequency hopping and actual PUSCH inter-repetition IAPR frequency hopping.

Specifically, one transmission of PUSCH configures one or more nominally repeated segments that are segmented based on slot boundaries and/or downlink symbols configured by RRC signaling to form actual repeated segments. Where the nominal repeated segment may be used for inp hopping and the actual repeated segment may be used for IAPR hopping.

And if IAPR frequency hopping is adopted, carrying out frequency hopping setting on the actual repeated segments. The actual repeated segments are formed by dividing the nominal repeated segments, which can cause a loss of diversity performance in frequency if the actual repeated segments are divided very unevenly or too finely.

A first preset symbol length (denoted N) may be set, which may be preset at the terminal device. When the symbol length of one of the actual repeated segments formed by dividing one nominal repeated segment is smaller than a first preset symbol length preset at the terminal equipment, the frequency hopping frequency of each divided actual repeated segment in one nominal repeated segment is equal to the frequency hopping frequency of the first actual repeated segment in each actual repeated segment.

The information of the first preset symbol length may also be configured through RRC signaling, for example, the information is encapsulated in a pusch-Config field or a configurable grantconfiguration field in RRC BWP-uplinkddedicated signaling, and is transmitted to the terminal device. For example, 2 bits juxtaposed to frequency hopping are added to the pusch-Config field or the configuredgontconfig field to indicate the first preset symbol length, and the 2 bits from 00 to 11 respectively indicate that the first preset symbol length is 0 to 3. Information of the first preset symbol length may be transmitted through the PDSCH.

The information of the first preset symbol length may be preset at the network device, and the network device encapsulates the information in a pusch-Config field or a configurable grantconfig field in the RRC BWP-uplinkddedicated signaling and transmits the information to the terminal device. The terminal device receives information of a first preset symbol length, for example, the information of the first preset symbol length is obtained in a pusch-Config field or a configurable grantconfigug field in an RRC BWP-uplinkddedicated signaling, and when a symbol length of one of actual repeated segments formed by dividing one nominal repeated segment is smaller than the first preset symbol length, a hopping frequency of each actual repeated segment divided in the one nominal repeated segment is made equal to a hopping frequency of the first actual repeated segment in each actual repeated segment.

The information of the frequency hopping type may be encapsulated in a pusch-Config field or a configuredGrantConfig field in the RRC BWP-uplinkddedicated signaling.

The receiving of the information of the PUSCH hopping type sent by the network device may be to acquire the PUSCH hopping type in a PUSCH-configuration field or a configured gradntconfiguration field in the RRC BWP-uplinkddedicated signaling sent by the network device. Information of a frequency hopping type may be received at the PDSCH.

Step S320 is: and determining time domain resource information at each frequency hopping frequency based on the PUSCH frequency hopping type information.

Specifically, the frequency hopping type is determined as IAPR frequency hopping or INPR frequency hopping through the information of the frequency hopping type, for example, time domain resource information of each actual repeated segment in the IAPR frequency hopping or time domain resource information of each nominal repeated segment in the INPR frequency hopping is determined.

Step S330 is: and transmitting the PUSCH data based on the time domain resource information.

Specifically, the PUSCH data is transmitted based on the time domain resource information of each actual repeated segment in IAPR frequency hopping and the corresponding frequency hopping frequency, or is transmitted based on the time domain resource information of each nominal repeated segment in INPR frequency hopping and the corresponding frequency hopping frequency.
