Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a method for allocating physical uplink shared channels and physical downlink shared channels. Background Technology

[0002] In 5G technology, to ensure coverage and transmission quality, repetition is introduced, allowing user equipment to repeatedly transmit the same transport block (TB) using one or more time slots. 5G NR Releases 15 / 16 introduced two types of repetition for PUSCH (Physical Uplink Shared Channel) repetition: Repetition Type A and Repetition Type B. Release 17 further introduced the TBoMS type for PUSCH repetition. Repetition Type A is characterized by transmitting one TB per repetition, and the symbols used in each time slot must be exactly the same. Repetition Type B is characterized by the fact that actual repetition cannot transmit a TB across time slots, and there is a problem of resource waste. TBoMS allows the transmission of a TB across time slots, but requires the same number of symbols allocated in each time slot. Furthermore, for PDSCH (Physical Downlink Shared Channel), 5G NR lacks a TB repetition type that spans time slots. In summary, existing technologies cannot utilize channel resources more flexibly and fully. Summary of the Invention

[0059] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0060] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0061] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0062] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0063] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0064] See Figure 1 , Figure 1 This is a flowchart of a physical uplink shared channel resource allocation method applied to user equipment according to an embodiment of the present invention, such as... Figure 1 As shown, it includes the following steps:

[0065] Step 101: Receive resource configuration information from the base station for repeated transmission of PUSCH (Physical Uplink Shared Channel), wherein the resource configuration information is used to indicate the number of time slots used for each repeated transmission of PUSCH.

[0066] It should be noted that PUSCH consists of multiple repeated transmissions, each of which transmits one TB (Transport Block), and the TB transmitted in each repeated transmission is the same.

[0067] Step 102: Determine the invalid symbols in the target time slot used for each repeated transmission of the PUSCH, and determine the target symbols in the target time slot other than the invalid symbols.

[0068] In this step, the user equipment checks each symbol in each target time slot of the PUSCH to determine whether it can be used as a valid symbol for uplink transmission. Symbols that cannot be used as valid symbols are called invalid symbols.

[0069] It should be noted that the number of symbols in the target time slot used for each PUSCH retransmission is determined after excluding invalid symbols. The number of symbols used in each target time slot can be different, so it is not constrained by the number of symbols and can flexibly utilize time slot resources.

[0070] Step 103: Transmit the TB modulation symbol of the PUSCH on the target symbol used in each PUSCH retransmission.

[0071] In this step, the symbol remaining after excluding all invalid symbols in the target time slot is the target symbol. The TB modulated symbol transmitted in each repetition of the PUSCH transmission is then sent on this target symbol.

[0072] In this embodiment of the invention, by receiving resource configuration information for PUSCH repetition transmission from a base station, the resource configuration information is used to indicate the number of time slots used in each PUSCH repetition transmission, determine invalid symbols in the target time slots used in each PUSCH repetition transmission, and determine the target symbols on the target time slots excluding the invalid symbols. The TB modulation symbols of the PUSCH are then transmitted on the target symbols used in each PUSCH repetition transmission. This fully utilizes available time slot resources, enabling flexible use of multiple consecutive or discontinuous time slots. Moreover, the number of symbols allocated in each time slot can be different, thus improving uplink performance.

[0073] In one specific embodiment of the present invention, the resource configuration information is indicated by either RRC (Radio Resource Control) signaling or DCI (Downlink Control information) received from the base station.

[0074] It should be noted that when the resource configuration information is indicated by RRC signaling received from the base station, this resource configuration information is semi-static and applicable to periodic PUSCH resources. Periodicity means that the channel resources used for each repeated PUSCH transmission are the same.

[0075] The information element numberOfSlots-1 can be added to the RRC signaling PUSCH-TimeDomainResourceAllocationList to indicate resource configuration information. The information element numberOfSlots-1 can be represented as follows:

[0076]

[0077] Where S1 represents the number of time slots used for the first repeated transmission of PUSCH; S2 represents the number of time slots used for the second repeated transmission of PUSCH, and so on for S3…S32, which will not be elaborated further.

[0078] S1+S2+S3…+S32 represents all the time slot resources used for repeated PUSCH transmissions.

[0079] Alternatively, if the resource configuration information is indicated by the DCI received from the base station, this resource configuration information is dynamically configured and applies to both periodic and aperiodic PUSCH resources. Aperiodic means that the channel resources used for each repeated PUSCH transmission are different.

[0080] The following fields can be added to the DCI responsible for PUSCH scheduling to indicate resource configuration information. The DCI format can be Format 0_0, Format 0_1, and Format 0_2, and the fields can be represented as follows:

[0081] type 1transmission indicator-1

[0082] type 1transmission indicator-2

[0083] type 1transmission indicator-3

[0084] …

[0085] type 1transmission indicator-32

[0086] Among them, type 1 transmission indicator-1 indicates the number of time slots used for the first repeated transmission of PUSCH; type 1 transmission indicator-2 indicates the number of time slots used for the second repeated transmission of PUSCH, and so on for S3…S32, which will not be elaborated further.

[0087] The total number of time slots corresponding to the above fields represents all time slot resources used for repeated PUSCH transmissions.

[0088] In one embodiment of the present invention, the resource configuration information is further used to indicate that the number of time slots used for each repeated transmission of the PUSCH is different.

[0089] It should be noted that the resource configuration information in the embodiments of the present invention can be used to indicate that the number of time slots used for each repeated transmission is different, thereby realizing flexible use of time slot resources and improving uplink performance.

[0090] See Figure 2 , Figure 2 This is a flowchart of a physical uplink shared channel resource allocation method applied to a base station according to an embodiment of the present invention, such as... Figure 2 As shown, it includes the following steps:

[0091] Step 201: Determine the resource configuration information for PUSCH retransmission, wherein the resource configuration information is used to indicate the number of time slots used in each PUSCH retransmission, and send the resource configuration information to the user equipment;

[0092] It should be noted that the base station determines the resource configuration information for PUSCH retransmission and sends this resource configuration information to the user equipment. PUSCH consists of multiple retransmissions, with each retransmission transmitting one TB, and the TB transmitted in each retransmission being the same.

[0093] Step 202: Determine the invalid symbols in the target time slot used for each repeated transmission of the PUSCH, and determine the target symbols in the target time slot other than the invalid symbols;

[0094] In this step, the base station detects each symbol in each target time slot of the PUSCH to determine whether it can be used as a valid symbol for uplink transmission. Symbols that cannot be used as valid symbols are called invalid symbols.

[0095] It should be noted that the symbols in the target time slot used for each PUSCH retransmission are determined after excluding invalid symbols. The number of symbols used in each target time slot can be different, so it is not constrained by the number of symbols and can flexibly utilize time slot resources.

[0096] Step 203: Receive the TB modulation symbol of the PUSCH on the target symbol used in each PUSCH retransmission.

[0097] In this step, the symbol remaining in the target time slot after excluding all invalid symbols is the target symbol. The TB modulated symbols transmitted in each repetition of the PUSCH are then received on this target symbol.

[0098] In this embodiment of the invention, by determining resource configuration information for repeated PUSCH transmissions, the resource configuration information is used to indicate the number of time slots used in each repeated PUSCH transmission and is sent to the user equipment. Then, invalid symbols in the target time slots used in each repeated PUSCH transmission are determined, as well as target symbols on the target time slots other than the invalid symbols. The TB modulation symbols of the PUSCH are received on the target symbols used in each repeated PUSCH transmission. This can fully utilize available time slot resources, flexibly utilize multiple consecutive or discontinuous time slots, and the number of symbols allocated in each time slot can be different, thereby improving uplink performance.

[0099] In one specific embodiment of the present invention, the resource configuration information is sent to the user equipment via either RRC signaling or DCI.

[0100] In other words, the base station instructs the user equipment (UE) on resource configuration information for PUSCH by sending either RRC signaling or DCI.

[0101] In one embodiment of the present invention, the resource configuration information is further used to indicate that the number of time slots used for each repeated transmission of the PUSCH is different.

[0102] See Figure 3 , Figure 3 This is a flowchart of a physical downlink shared channel resource allocation method applied to user equipment according to an embodiment of the present invention, such as... Figure 3 As shown, it includes the following steps:

[0103] Step 301: Receive resource configuration information from the base station for repeated transmission of PDSCH (Physical Downlink Shared Channel), wherein the resource configuration information is used to indicate the number of time slots used for each repeated transmission of PDSCH.

[0104] It should be noted that PDSCH consists of multiple repeated transmissions, each of which transmits one TB, and the TB transmitted in each repeated transmission is the same. The number of time slots used in each repeated transmission can be the same or different, and cross-time slot transmission is supported.

[0105] In this embodiment of the invention, resource configuration information for repeated PDSCH transmission is received from the base station. The resource configuration information is used to indicate the number of time slots used for each repeated PDSCH transmission, thereby solving the problem of PDSCH resource allocation, realizing PDSCH cross-time slot transmission, and improving downlink performance.

[0106] In one specific embodiment of the present invention, the resource configuration information is indicated by either RRC signaling or DCI received from the base station.

[0107] It should be noted that the aforementioned resource configuration information can be either first resource configuration information or second resource configuration information. Both the first and second resource configuration information are indicated by either RRC signaling or DCI received from the base station. The difference between the two is that the first resource configuration information is used to indicate that the number of time slots used in each repeated transmission of PDSCH is the same, while the second resource configuration information is used to indicate that the number of time slots used in each repeated transmission of PDSCH is different.

[0108] Wherein, if the first resource configuration information is indicated by RRC signaling received from the base station, the first resource configuration information is semi-static resource configuration information.

[0109] The information elements numberOfRepetitionsExt and numberOfSlots-2 can be added to the RRC signaling PDSCH-TimeDomainResourceAllocationList to indicate the first resource configuration information. The added information elements can be represented as follows:

[0110]

[0111] Where numberOfRepetitionsEx represents the number of times PDSCH is repeatedly transmitted, M;

[0112] numberOfSlots-2 represents the number of time slots N used in each repeated transmission of PDSCH;

[0113] N*M represents the total time slot resources used for repeated PDSCH transmissions.

[0114] Alternatively, if the first resource configuration information is indicated by the DCI received from the base station, the first resource configuration information is dynamically configured resource configuration information.

[0115] Add the following field to the DCI responsible for PDSCH scheduling to indicate the first resource configuration information. The DCI format can be Format 0_0, Format 0_1, or Format 0_2, and the field can be represented as follows:

[0116] type 2transmission indicator-1

[0117] type 2transmission indicator-2

[0118] type 2transmission indicator-3

[0119] …

[0120] type 2transmission indicator-32

[0121] Among them, type 2transmission indicator-1 indicates the number of time slots used for the first repeated transmission of PDSCH; type 2transmission indicator-2 indicates the number of time slots used for the second repeated transmission of PDSCH, and so on for S3…S32, which will not be elaborated further.

[0122] The total number of time slots corresponding to the above fields represents all time slot resources used for repeated PDSCH transmissions.

[0123] When the second resource configuration information is indicated by RRC signaling received from the base station, this second resource configuration information is a semi-static resource configuration information, applicable to periodic PDSCH resources. Periodicity means that the channel resources used for each repeated PDSCH transmission are the same.

[0124] The cell numberOfSlots-3 can be added to the RRC signaling PDSCH-TimeDomainResourceAllocationList to indicate the second resource configuration information. The cell numberOfSlots-3 can be represented as follows:

[0125]

[0126] Wherein, S1 represents the number of time slots used in the first repeated transmission of PDSCH; S2 represents the number of time slots used in the second repeated transmission of PDSCH, and so on for S3...S32, which will not be elaborated further.

[0127] S1+S2+S3…+S32 represents all the time slot resources used for repeated PDSCH transmissions.

[0128] Alternatively, if the second resource configuration information is indicated by the DCI received from the base station, this second resource configuration information is dynamically configured resource configuration information, applicable to both periodic and aperiodic PDSCH resources. Here, aperiodic means that the channel resources used for each repeated PDSCH transmission are different.

[0129] The following fields can be added to the DCI responsible for PDSCH scheduling to indicate the second resource configuration information. The DCI format can be Format 0_0, Format 0_1, and Format 0_2, and the fields can be represented as follows:

[0130] type 3transmission indicator-1

[0131] type 3transmission indicator-2

[0132] type 3transmission indicator-3

[0133] …

[0134] type 3transmission indicator-32

[0135] Among them, type 3transmission indicator-1 indicates the number of time slots used for the first repeated transmission of PDSCH; type 3transmission indicator-2 indicates the number of time slots used for the second repeated transmission of PDSCH, and so on for S3…S32, which will not be elaborated further.

[0136] The total number of time slots corresponding to the above fields represents all time slot resources used for repeated PDSCH transmissions.

[0137] In one embodiment of the present invention, after step 301, the above method further includes:

[0138] Identify invalid symbols in the target time slot used in each repeated transmission of the PDSCH, and identify target symbols in the target time slot other than the invalid symbols;

[0139] The TB modulation symbol of the PDSCH is received on the target symbol used in each PDSCH retransmission.

[0140] It should be noted that when receiving the second resource configuration information for PDSCH repetition from the base station, the user equipment first detects each symbol in each target time slot of the PDSCH to determine whether it can be used as a valid symbol for downlink transmission. Symbols that cannot be used as valid symbols are invalid symbols.

[0141] Then, the symbols remaining after excluding all invalid symbols in the target time slot are the target symbols. The TB modulated symbols transmitted in each repeated transmission of PDSCH are received on the target symbols. The number of symbols used in each target time slot can be different, so it is not constrained by the number of symbols and can flexibly utilize time slot resources.

[0142] In one embodiment of the present invention, when receiving first resource configuration information or second resource configuration information for repeated PDSCH transmission from the base station, the above method further includes:

[0143] The base station receives retransmission type information, which is used to indicate whether to select either the first resource configuration information or the second resource configuration information to determine the number of time slots used for each retransmission of the PDSCH. The first resource configuration information is used to indicate that the number of time slots used for each retransmission of the PDSCH is the same, and the second resource configuration information is used to indicate that the number of time slots used for each retransmission of the PDSCH is different.

[0144] It should be noted that the user equipment receives repetition transmission type information from the base station, and then selects either the first resource configuration information or the second resource configuration information to determine the number of time slots used for each repetition of PDSCH. Both the first and second resource configuration information are indicated by either RRC signaling or DCI received from the base station. The difference is that the first resource configuration information indicates that the number of time slots used for each repetition of PDSCH is the same, while the second resource configuration information indicates that the number of time slots used for each repetition of PDSCH is different.

[0145] See Figure 4 , Figure 4 This is a flowchart of a physical downlink shared channel resource allocation method applied to a base station according to an embodiment of the present invention, such as... Figure 4 As shown, it includes the following steps:

[0146] Step 401: Determine the resource configuration information for repeated PDSCH transmissions, wherein the resource configuration information is used to indicate the number of time slots used in each repeated PDSCH transmission, and send the resource configuration information to the user equipment.

[0147] It should be noted that PDSCH consists of multiple repeated transmissions, each of which transmits one TB, and the TB transmitted in each repeated transmission is the same. The number of time slots used in each repeated transmission can be the same or different, and cross-time slot transmission is supported.

[0148] In this embodiment of the invention, resource configuration information for repeated PDSCH transmission is determined. The resource configuration information is used to indicate the number of time slots used in each repeated PDSCH transmission and is sent to the user equipment, thereby solving the problem of PDSCH resource allocation, realizing PDSCH cross-time slot transmission, and improving downlink performance.

[0149] In one specific embodiment of the present invention, the resource configuration information is sent to the user equipment via either RRC signaling or DCI.

[0150] In other words, the base station instructs the user equipment (UE) on resource configuration information for PDSCH by sending either RRC signaling or DCI.

[0151] In one embodiment of the present invention, after step 401, the above method further includes:

[0152] Identify invalid symbols in the target time slot used in each repeated transmission of the PDSCH, and identify target symbols in the target time slot other than the invalid symbols;

[0153] The TB modulation symbol of the PDSCH is transmitted on the target symbol used in each retransmission of the PDSCH.

[0154] It should be noted that the second resource configuration information is used to indicate that the number of time slots used for each repeated transmission of the PDSCH is different. When the second resource configuration information for repeated transmission of PDSCH is sent to the user equipment, the base station first detects each symbol in each target time slot of the PDSCH to determine whether it can be used as a valid symbol for downlink transmission. Symbols that cannot be used as valid symbols are invalid symbols.

[0155] Then, the symbols remaining after excluding all invalid symbols in the target time slot are the target symbols. The TB modulated symbols transmitted in each repeated transmission of PDSCH are sent on the target symbols. The number of symbols used in each target time slot can be different, so it is not constrained by the number of symbols and can flexibly utilize time slot resources.

[0156] In one embodiment of the present invention, when sending first resource configuration information or second resource configuration information for repeated PDSCH transmission to the user equipment, the above method further includes:

[0157] The user equipment is sent with repeat transmission type information, which is used to instruct the user equipment to select either the first resource configuration information or the second resource configuration information to determine the number of time slots used for each repeat transmission of the PDSCH. The first resource configuration information is used to indicate that the number of time slots used for each repeat transmission of the PDSCH is the same, and the second resource configuration information is used to indicate that the number of time slots used for each repeat transmission of the PDSCH is different.

[0158] It should be noted that the base station instructs the user equipment (UE) to select either the first resource configuration information or the second resource configuration information to determine the number of time slots used in each PDSCH repetition by sending repetition transmission type information. Both the first and second resource configuration information are indicated by sending either RRC signaling or DCI to the UE. The difference lies in that the first resource configuration information indicates that the number of time slots used in each PDSCH repetition is the same, while the second resource configuration information indicates that the number of time slots used in each PDSCH repetition is different.

[0161] The first determining module 502 is used to determine invalid symbols in the target time slot used in each repeated transmission of the PUSCH, and to determine target symbols in the target time slot other than the invalid symbols;

[0162] The first transmitting module 503 is used to transmit the transport block TB modulation symbol of the PUSCH on the target symbol used in each PUSCH retransmission.

[0163] In this embodiment of the invention, by receiving resource configuration information for PUSCH repetition transmission from a base station, the resource configuration information is used to indicate the number of time slots used in each PUSCH repetition transmission, determine invalid symbols in the target time slots used in each PUSCH repetition transmission, and determine the target symbols on the target time slots excluding the invalid symbols. The TB modulation symbols of the PUSCH are then transmitted on the target symbols used in each PUSCH repetition transmission. This fully utilizes available time slot resources, enabling flexible use of multiple consecutive or discontinuous time slots. Moreover, the number of symbols allocated in each time slot can be different, thus improving uplink performance.

[0164] Optionally, the resource configuration information is indicated by either Radio Resource Control (RRC) signaling or Downlink Control Information (DCI) received from the base station.
