Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to channel transmission methods and apparatus, and storage media. Background Technology

[0002] To improve uplink coverage, terminals can perform repeated PUSCH (Physical Uplink Shared Channel) transmissions. The base station can combine the received repeated PUSCH signals to achieve a higher signal-to-noise ratio. Currently, the base station supports semi-static or dynamic indication of the actual repetition count K. Terminals can perform repeated PUSCH transmissions over K consecutive time slots.

[0003] The existing PUSCH repetition type A scheme, although nominally configurable to a maximum of 16 repetitions, suffers from significant performance degradation in some TDD (Time Division Duplex) systems with a large number of downlink time slots, such as those with a ratio of 7:3 or 4:1 between downlink and uplink data transmission slots. This results in a large number of unavailable transmission resources, causing PUSCH repetitions to be canceled. Consequently, the actual number of repetitions is far less than the nominally configured number K, severely degrading uplink coverage performance. Summary of the Invention

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

[0125] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0126] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0127] In some TDD configuration scenarios, such as when the ratio of the number of time slots used for downlink data transmission to the number of time slots used for uplink data transmission is 7:3, the actual number of times PUSCH is only 4.8 when the maximum number of repeated transmissions of PUSCH is 16.

[0128] For urban 4GHz TDD, when the Inter-Scell ​​Distance (ISD) is set to 400 meters, approximately an 8dB (gain) performance gap needs to be compensated. Simulations show that at least 16 actual repetitions are required to achieve PUSCH coverage. When the ISD is extended to 500 meters, a 10dB performance gap needs to be compensated.

[0129] Clearly, given the current protocol's maximum number of repeated transmissions of 16, the actual number of repeated transmissions of the PUSCH is insufficient to meet the uplink coverage requirements.

[0130] To address this issue, the present disclosure provides the following channel transmission scheme.

[0131] The first approach, by default, supports and enables raising the upper limit of the range of the maximum number of repeated transmissions, and modifies the counting method for the actual number of repeated transmissions.

[0132] Let's first introduce the first solution from the terminal side.

[0133] Reference Figure 1 As shown, Figure 1 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0134] In step 101, the maximum number of repeated transmissions of the target Physical Uplink Shared Channel (PUSCH) is determined. The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0135] In this embodiment of the disclosure, the upper limit of the first interval range can be a positive integer greater than 16, including but not limited to 32, 64, or 128. Accordingly, the first interval range includes [1, 32], [1, 64], or [1, 128], etc.

[0136] Within the aforementioned first interval, the base station determines the maximum number of repeated transmissions of the target PUSCH for the terminal. Further, it sends the configured maximum number of repeated transmissions to the terminal through RRC (Radio Resource Control) parameters. Based on the RRC parameters, the terminal determines the maximum number of repeated transmissions of the target PUSCH configured by the base station. These RRC parameters include, but are not limited to, the pusch-AggregationFactor (PUSCH aggregation parameter).

[0137] In step 102, the actual number of repeated transmissions is determined based on the maximum number of repeated transmissions.

[0138] In this embodiment of the disclosure, the actual number of repeated transmissions is less than or equal to the maximum number of repeated transmissions.

[0139] In step 103, based on the actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0140] In related technologies, when counting the actual number of PUSCH retransmissions, even if a certain time-domain transmission resource is unavailable, it is still counted as one actual retransmission of the PUSCH. In the embodiments of this disclosure, the counting method for counting the actual number of retransmissions can be modified to only determine multiple available uplink time-domain transmission resources that can be used for retransmitting the target PUSCH.

[0141] In this embodiment of the disclosure, the terminal can, based on a preset time-domain transmission resource configuration method, skip unavailable time-domain transmission resources from a plurality of sequentially determined time-domain transmission resources, and determine the plurality of available uplink time-domain transmission resources until the number of the plurality of available uplink time-domain transmission resources is the same as the actual number of repeated transmissions. The unavailable time-domain transmission resources include, but are not limited to, downlink time-domain transmission resources, and the preset time-domain transmission resource configuration method includes, but is not limited to, methods for indicating the transmission methods corresponding to the plurality of time-domain transmission resources.

[0142] For example, among 10 sequentially adjacent time-domain transmission resources, according to the preset time-domain transmission resource configuration method, the first 8 time-domain transmission resources are used to transmit downlink data and are therefore unavailable and need to be skipped. The terminal then uses the 2 time-domain transmission resources used to transmit uplink data as available uplink time-domain transmission resources. This process continues until the number of determined available uplink time-domain transmission resources is the same as the actual number of repeated transmissions.

[0143] In step 104, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0144] In the above embodiment, the maximum number of repeated transmissions is within a first interval, and the upper limit of the first interval is greater than 16. The terminal determines the actual number of repeated transmissions based on the maximum number of repeated transmissions within the first interval, and determines multiple available uplink time-domain transmission resources based on the actual number of repeated transmissions. This allows the target PUSCH to be repeatedly transmitted on multiple available uplink time-domain transmission resources. This increases the actual number of repeated transmissions of the PUSCH, improving uplink coverage performance.

[0145] Reference Figure 2 As shown, Figure 2 This is a flowchart illustrating a channel transmission method according to an embodiment. The method can be used in a terminal and may include the following steps:

[0146] In step 201, the maximum number of repeated transmissions of the target Physical Uplink Shared Channel (PUSCH) is determined. The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0147] In this embodiment of the disclosure, the upper limit of the first interval range can be a positive integer greater than 16, including but not limited to 32, 64 or 128. Accordingly, the first interval range includes [1, 32], [1, 64] or [1, 128].

[0148] Within the aforementioned first interval, the base station determines the maximum number of repeated transmissions of the target PUSCH for the terminal. Further, it sends the configured maximum number of repeated transmissions to the terminal through RRC (Radio Resource Control) parameters. Based on the state RRC parameters, the terminal determines the maximum number of repeated transmissions of the target PUSCH configured by the base station. These RRC parameters include, but are not limited to, the pusch-AggregationFactor (PUSCH aggregation parameter).

[0149] In step 202, in response to the absence of a downlink control signaling (DCI) containing an indication of the actual number of repeated transmissions, the maximum number of repeated transmissions is taken as the actual number of repeated transmissions.

[0150] In this embodiment of the disclosure, if the terminal does not receive the aforementioned DCI (Downlink Control Information), the maximum number of repeated transmissions is directly used as the actual number of repeated transmissions. For example, if the maximum number of repeated transmissions is 32, then the actual number of repeated transmissions is also 32.

[0151] In step 203, based on the actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0152] In this embodiment of the disclosure, the method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 described above, and will not be repeated here.

[0153] In step 204, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0154] In the above embodiments, the terminal can use the maximum number of repeated transmissions configured by the base station within the first interval as the actual number of repeated transmissions, thereby determining multiple available uplink time-domain transmission resources. This allows the target PUSCH to be repeatedly transmitted on multiple available uplink time-domain transmission resources. This increases the actual number of repeated transmissions of the PUSCH, improving uplink coverage performance.

[0155] Reference Figure 3 As shown, Figure 3 This is a flowchart illustrating a channel transmission method according to an embodiment, which may include the following steps:

[0156] In step 301, the maximum number of repeated transmissions of the target Physical Uplink Shared Channel (PUSCH) is determined. The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0157] In this embodiment of the disclosure, the upper limit of the first interval range can be a positive integer greater than 16, including but not limited to 32, 64 or 128. Accordingly, the first interval range includes [1, 32], [1, 64] or [1, 128].

[0158] Within the aforementioned first interval, the base station determines the maximum number of repeated transmissions of the target PUSCH for the terminal. Further, it sends the configured maximum number of repeated transmissions to the terminal through RRC (Radio Resource Control) parameters. Based on the state RRC parameters, the terminal determines the maximum number of repeated transmissions of the target PUSCH configured by the base station. These RRC parameters include, but are not limited to, the pusch-AggregationFactor (PUSCH aggregation parameter).

[0159] In step 302, in response to receiving a first downlink control signaling (DCI) containing an indication of the actual number of repeated transmissions, the actual number of repeated transmissions indicated by the first DCI is determined in a first TDRA table corresponding to the first interval range.

[0160] In related technologies, the TDRA (Time Domain Resource Allocation) table includes at least one entry for the number of repeated transmissions of a PUSCH. Each row of the TDRA table corresponds to a different number of repeated transmissions of a PUSCH, and the number of rows in the TDRA table is the same as the maximum number of repeated transmissions specified in the protocol. That is, the current protocol specifies a maximum number of repeated transmissions of 16, corresponding to a 16-row TDRA table, with each row including at least one number of repeated transmissions of a PUSCH.

[0161] After the base station sends the maximum number of repeated transmissions to the terminal, it can instruct a row in the TDRA table via DCI. The terminal, based on the DCI instruction, uses the number of repeated transmissions of the PUSCH corresponding to that row in the TDRA table as the actual number of repeated transmissions. The actual number of repeated transmissions is less than or equal to the maximum number of repeated transmissions configured by the base station.

[0162] For example, the base station configures the maximum number of repeated transmissions of the target PUSCH by the RRC parameter to be 10 times, and the actual number of repeated transmissions indicated by the DCI is less than or equal to 10 times.

[0163] In this embodiment of the disclosure, since the upper limit of the maximum number of repeated transmissions is increased, it is necessary to expand the original TDRA table specified in the protocol by increasing the number of rows in the TDRA table to obtain a first TDRA table corresponding to the first interval range. For example, if the upper limit of the maximum number of repeated transmissions is 32, then the first TDRA table needs to include 32 rows, each row corresponding to a different number of repeated transmissions for PUSCH.

[0164] After receiving the first DCI, the terminal determines the row indicated by the first DCI in the first TDRA table and uses the number of repeated transmissions of PUSCH included in that row as the actual number of repeated transmissions.

[0165] In this embodiment, the number of bits occupied by the information field in the first DCI used to indicate the actual number of retransmissions also needs to be expanded, and needs to be greater than a preset number. The preset number is the number of bits occupied by this information field in the DCI specified in the existing protocol. For example, if the maximum number of retransmissions specified in the existing protocol is 16, and the information field in the DCI used to indicate the actual number of retransmissions needs to occupy 5 bits, then the preset number is 5. In this disclosure, the number of bits occupied by this information field in the first DCI is greater than 5.

[0166] In step 303, based on the actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0167] In this embodiment of the disclosure, the method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 described above, and will not be repeated here.

[0168] In step 304, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0169] In the above embodiments, after determining the maximum number of repeated transmissions, the terminal can determine the actual number of repeated transmissions of the target PUSCH in the extended first TDRA table based on the DCI instruction, thereby increasing the actual number of repeated transmissions of the PUSCH and improving the uplink coverage performance.

[0170] Next, we will introduce the first channel transmission scheme from the base station side. (Refer to...) Figure 4 As shown, Figure 4 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a base station and may include the following steps:

[0171] In step 401, Radio Resource Control (RRC) parameters are sent. The RRC parameters are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0172] In this embodiment of the disclosure, the base station can configure the maximum number of repeated transmissions of the target PUSCH for the terminal within a first interval range, and then send the configured maximum number of repeated transmissions to the terminal through RRC parameters, including but not limited to pusch-AggregationFactor.

[0173] In the above embodiments, the base station can send the maximum number of repeated transmissions within the first interval range to the terminal through the RRC parameter. The terminal can directly use the maximum number of repeated transmissions as the actual number of repeated transmissions without receiving the downlink control signaling (DCI) that indicates the actual number of repeated transmissions, thereby increasing the actual number of repeated transmissions of the terminal's PUSCH and improving the uplink coverage performance.

[0174] Reference Figure 5 As shown, Figure 5 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a base station and may include the following steps:

[0175] In step 501, Radio Resource Control (RRC) parameters are sent. The RRC parameters are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0176] In step 502, the first downlink control signaling (DCI) is sent.

[0177] In this embodiment of the disclosure, the first DCI is used to instruct the terminal to determine the actual number of repeated transmissions of the target PUSCH in the first Time Domain Resource (TDRA) table corresponding to the first interval range. The number of rows in the first TDRA table is the same as the upper limit of the maximum number of repeated transmissions. The number of bits occupied by the information field in the first DCI used to indicate the actual number of repeated transmissions is greater than a preset number.

[0178] In the above embodiments, in addition to sending RRC parameters to indicate the maximum number of repeated transmissions of the target PUSCH by the terminal, the base station can also dynamically select the actual number of repeated transmissions of the target PUSCH from the first TDRA table through the first DCI, thereby increasing the actual number of repeated transmissions of the PUSCH by the terminal and improving the uplink coverage performance.

[0179] In some alternative embodiments, refer to Figure 6 As shown, Figure 6 This is a flowchart illustrating a channel transmission method according to an embodiment, including the following steps:

[0180] In step 601, the base station sends Radio Resource Control (RRC) parameters, which are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0181] In this embodiment, the upper limit of the first interval is assumed to be 32. The base station determines the maximum number of repeated transmissions within the first interval, also assuming the maximum number of repeated transmissions is 32. The base station sends the maximum number of repeated transmissions to the terminal via RRC parameters. In practical applications, the upper limit of the first interval can be any positive integer greater than 16, including but not limited to 64, 128, etc.

[0182] In step 602, in response to not receiving downlink control signaling (DCI) containing an indication of the actual number of repeated transmissions, the terminal uses the maximum number of repeated transmissions as the actual number of repeated transmissions.

[0183] In this embodiment of the disclosure, the maximum number of repeated transmissions is 32, so the actual number of repeated transmissions is also 32.

[0184] In step 603, the terminal, based on a preset time-domain transmission resource configuration method, skips unavailable time-domain transmission resources from a plurality of sequentially determined time-domain transmission resources and determines the plurality of available uplink time-domain transmission resources until the number of the plurality of available uplink time-domain transmission resources is the same as the actual number of repeated transmissions.

[0185] In this embodiment of the disclosure, unavailable time-domain transmission resources include, but are not limited to, downlink time-domain transmission resources. The method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 above, and will not be repeated here.

[0186] In step 604, the terminal repeatedly transmits the target PUSCH on the plurality of available uplink time domain resources.

[0187] In the above embodiments, the upper limit of the range of the maximum number of repeated transmissions is increased, and the counting method for the actual number of repeated transmissions is modified, thereby increasing the actual number of repeated transmissions of the terminal's PUSCH and improving the uplink coverage performance.

[0188] In some alternative embodiments, refer to Figure 7 As shown, Figure 7 This is a flowchart illustrating a channel transmission method according to an embodiment, which may include the following steps:

[0189] In step 701, the base station sends Radio Resource Control (RRC) parameters, which are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range, which includes a first range, the upper limit of which is greater than 16.

[0190] In this embodiment of the disclosure, the upper limit of the first interval is assumed to be 32. The base station determines the maximum number of repeated transmissions within the first interval, also assuming the maximum number of repeated transmissions is 32. The base station sends the maximum number of repeated transmissions to the terminal via RRC parameters.

[0191] In step 702, the base station sends the first DCI to the terminal.

[0192] In the first DCI, the number of bits occupied by the information field used to indicate the actual number of repeated transmissions is greater than a preset number.

[0193] In step 703, the terminal determines the actual number of repeated transmissions indicated by the first DCI in the first TDRA table corresponding to the first interval range.

[0194] In this embodiment of the disclosure, the first TDRA table has 32 rows.

[0195] In step 704, the terminal, based on a preset time-domain transmission resource configuration method, skips unavailable time-domain transmission resources from a plurality of sequentially determined time-domain transmission resources and determines the plurality of available uplink time-domain transmission resources until the number of the plurality of available uplink time-domain transmission resources is the same as the actual number of repeated transmissions.

[0196] In this embodiment of the disclosure, unavailable time-domain transmission resources include, but are not limited to, downlink time-domain transmission resources. The method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 above, and will not be repeated here.

[0197] In step 705, the terminal repeatedly transmits the target PUSCH on the plurality of available uplink time domain resources.

[0198] In the above embodiments, the upper limit of the range of the maximum number of repeated transmissions is increased, and the counting method for the actual number of repeated transmissions is modified, thereby increasing the actual number of repeated transmissions of the terminal's PUSCH and improving the uplink coverage performance.

[0199] In addition to the first channel transmission scheme described above, this disclosure also provides another channel transmission scheme, as follows:

[0200] The second approach involves modifying the counting method for actual repeated transmissions, maintaining at least two TDRA tables in the protocol.

[0201] Let's first introduce the second solution from the perspective of the terminal side.

[0202] Reference Figure 8 As shown, Figure 8 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0203] In step 801, the maximum number of repeated transmissions of the target Physical Uplink Shared Channel (PUSCH) is determined. The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0204] In this embodiment, it is also necessary to modify the upper limit of the maximum number of repeated transmissions of the PUSCH in the protocol. The second interval range can be [1, 16], and the third interval range can be [17, N], where N is a positive integer greater than 17. To correspond with the second interval range, N can be 32. In practical applications, the preset interval range can also include at least one fourth interval range, for example, the fourth interval range is [33, 48]. This disclosure does not limit this.

[0205] The maximum number of repeated transmissions configured by the base station for the terminal through the RRC parameters can be less than 16 or greater than 16 but less than the upper limit of the third interval range, that is, it can be within the second interval range or within the third interval range.

[0206] In step 802, the actual number of repeated transmissions is determined based on the maximum number of repeated transmissions.

[0207] In this embodiment of the disclosure, the actual number of repeated transmissions is less than or equal to the maximum number of repeated transmissions.

[0208] In step 803, based on the actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0209] In step 804, the target PUSCH is repeatedly transmitted over the plurality of available uplink time domain resources.

[0210] In the above embodiments, the maximum number of repeated transmissions falls within a preset interval, which includes at least a second interval and a third interval. The terminal determines the actual number of repeated transmissions based on the maximum number of repeated transmissions, and then determines multiple available uplink time-domain transmission resources based on the actual number of repeated transmissions. This allows the target PUSCH to be repeatedly transmitted on multiple available uplink time-domain transmission resources. This increases the actual number of repeated transmissions of the PUSCH, improving uplink coverage performance.

[0211] Reference Figure 9 As shown, Figure 9 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0212] In step 901, the maximum number of repeated transmissions of the target Physical Uplink Shared Channel (PUSCH) is determined. The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0213] In step 902, in response to the absence of a downlink control signaling (DCI) containing an indication of the actual number of repeated transmissions, the maximum number of repeated transmissions is taken as the actual number of repeated transmissions.

[0214] In step 903, based on the actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0215] In this embodiment of the disclosure, the method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 described above, and will not be repeated here.

[0216] In step 904, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0217] In the above embodiments, the terminal can use the maximum number of repeated transmissions configured by the base station as the actual number of repeated transmissions, and thus determine multiple available uplink time-domain transmission resources. This allows the target PUSCH to be repeatedly transmitted on multiple available uplink time-domain transmission resources. This increases the actual number of repeated transmissions of the PUSCH, improving uplink coverage performance.

[0218] Reference Figure 10 As shown, Figure 10 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0219] In step 1001, the maximum number of repeated transmissions of the target Physical Uplink Shared Channel (PUSCH) is determined. The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0220] In step 1002, a target TDRA table is determined at least in the second TDRA table corresponding to the second interval range and the third TDRA table corresponding to the third interval range.

[0221] In this embodiment of the disclosure, the second TDRA table corresponding to the second interval range can be a TDRA table agreed upon in an existing protocol, and the maximum number of repeated transmissions of PUSCH included is 16. The third TDRA table corresponding to the third interval range can be a newly added TDRA table, which can correspond to the second TDRA table, including 16 rows, each row indicating a different number of repeated transmissions of PUSCH, and the lower limit of the number of repeated transmissions of PUSCH indicated by the third TDRA table is 17, and the upper limit is 32.

[0222] The terminal can determine a target TDRA table, at least in the second and third TDRA tables, based on the indication of the received target RRC signaling.

[0223] In step 1003, the actual number of repeated transmissions indicated by the received second DCI is determined in the target TDRA table.

[0224] In this embodiment of the disclosure, the second DCI can indicate the row number of the actual repeated transmissions in the target TDRA table, and the terminal determines the actual repeated transmissions in the target TDRA table according to the indication of the second DCI.

[0225] For example, if the target TDRA table is the second TDRA table and the second DCI indicates row 16, then the actual number of repeated transmissions is 16. If the target TDRA table is the third TDRA table and the second DCI indicates row 16, then the actual number of repeated transmissions is 32. Similarly, if the protocol maintains more than two TDRA tables in this scheme, the same method can be used to determine the actual number of repeated transmissions.

[0226] It should be noted that if the number of rows in the third TDRA table does not exceed 16, then the number of bits occupied by the information field in the second DCI used to indicate the actual number of repeated transmissions is a preset number. This preset number is the number of bits occupied by this information field in the DCI as specified in existing protocols.

[0227] In step 1004, based on the actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0228] In this embodiment of the disclosure, the method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 described above, and will not be repeated here.

[0229] In step 1005, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0230] In the above embodiments, after determining the maximum number of repeated transmissions, the terminal can determine the target TDRA table from at least two TDRA tables, and then, based on the indication of the second DCI, determine the actual number of repeated transmissions of the target PUSCH in the target TDRA table, thereby increasing the actual number of repeated transmissions of the PUSCH and improving the uplink coverage performance.

[0231] In some optional embodiments, the terminal may report first auxiliary information to the base station. The first auxiliary information is used to assist the base station in determining the target TDRA table from at least two TDRA tables. The first auxiliary information includes, but is not limited to, the decoding performance of the terminal's last received downlink data and the measurement results of the terminal's measurement of the downlink channel reception quality.

[0232] Next, we will introduce the second channel transmission scheme from the base station side. (Refer to...) Figure 11 As shown, Figure 11 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a base station and may include the following steps:

[0233] In step 1101, Radio Resource Control (RRC) parameters are sent. The RRC parameters are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0234] In this embodiment of the disclosure, the preset interval range includes at least a second interval range and a third interval range. The maximum number of repeated transmissions configured by the base station is located within the second interval range or the third interval range, or within another interval range included in the preset interval range. The base station can send the configured maximum number of repeated transmissions to the terminal via RRC parameters, which include, but are not limited to, the pusch-AggregationFactor.

[0235] In the above embodiments, the base station can send the maximum number of repeated transmissions to the terminal through the RRC parameter. The terminal can directly use the maximum number of repeated transmissions as the actual number of repeated transmissions even without receiving the downlink control signaling (DCI) that indicates the actual number of repeated transmissions. This increases the actual number of repeated transmissions of the terminal's PUSCH and improves the uplink coverage performance.

[0236] Reference Figure 12 As shown, Figure 12 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a base station and may include the following steps:

[0237] In step 1201, Radio Resource Control (RRC) parameters are sent. The RRC parameters are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0238] In step 1202, a target TDRA table is determined from at least the second time-domain resource allocation TDRA table corresponding to the second interval range and the third TDRA table corresponding to the third interval range.

[0239] In this embodiment of the disclosure, the base station may determine the target TDRA table using any of the following methods, but not limited to.

[0240] In one possible implementation, the base station can determine the target TDRA table based on the network-side coverage enhancement target. For example, if the maximum number of repeated transmissions of the target PUSCH by the terminal is determined to be 16 based on the network-side coverage enhancement target, then the second TDRA table is selected as the target TDRA table; if the maximum number of repeated transmissions of the target PUSCH by the terminal is determined to be 32, then the third TDRA table is selected as the target TDRA table.

[0241] In another possible implementation, the base station can determine the target TDRA table based on the measurement results of uplink channel reception quality. For example, if the base station's measurement results of uplink channel reception quality indicate that the maximum number of retransmissions of the target PUSCH by the terminal is 32, then the base station determines the third TDRA table as the target TDRA table.

[0242] In another possible implementation, the base station can determine the target TDRA table based on the first auxiliary information reported by the terminal. The first auxiliary information includes, but is not limited to, the decoding performance of the terminal's last received downlink data and the measurement results of the terminal's measurement of the downlink channel reception quality.

[0243] In step 1203, target RRC signaling for indicating the target TDRA form is sent.

[0244] In step 1204, a second downlink control signaling (DCI) is sent.

[0245] In this embodiment of the disclosure, the second DCI is used to instruct the terminal to determine the actual number of repeated transmissions of the target PUSCH in the target TDRA table. When the number of rows in the third TDRA table does not exceed 16, the number of bits occupied by the information field in the second DCI used to indicate the actual number of repeated transmissions is a preset number.

[0246] In the above embodiments, in addition to sending RRC parameters to indicate the maximum number of repeated transmissions of the target PUSCH by the terminal, the base station can also determine the target TDRA table from at least two TDRA tables, indicate the target TDRA table through target RRC signaling, and dynamically select the actual number of repeated transmissions of the target PUSCH from the target TDRA table through the second DCI, thereby increasing the actual number of repeated transmissions of the PUSCH by the terminal and improving the uplink coverage performance.

[0247] In some alternative embodiments, refer to Figure 13 As shown, Figure 13 This is a flowchart illustrating a channel transmission method according to an embodiment, including the following steps:

[0248] In step 1301, the base station sends Radio Resource Control (RRC) parameters. The RRC parameters are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0249] In step 1302, in response to not receiving downlink control signaling (DCI) containing an indication of the actual number of repeated transmissions, the terminal uses the maximum number of repeated transmissions as the actual number of repeated transmissions.

[0250] In this embodiment of the disclosure, the maximum number of repeated transmissions is 32, so the actual number of repeated transmissions is also 32.

[0251] In step 1303, the terminal, based on a preset time-domain transmission resource configuration method, skips unavailable time-domain transmission resources from a plurality of sequentially determined time-domain transmission resources and determines the plurality of available uplink time-domain transmission resources until the number of the plurality of available uplink time-domain transmission resources is the same as the actual number of repeated transmissions.

[0252] In this embodiment of the disclosure, unavailable time-domain transmission resources include, but are not limited to, downlink time-domain transmission resources. The method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 above, and will not be repeated here.

[0253] In step 1304, the terminal repeatedly transmits the target PUSCH on the plurality of available uplink time domain resources.

[0254] In the above embodiments, the counting method for the actual number of repeated transmissions is modified, and at least two TDRA tables need to be maintained in the protocol, which increases the actual number of repeated transmissions of PUSCH by the terminal and improves the uplink coverage performance.

[0255] In some alternative embodiments, refer to Figure 14 As shown, Figure 14 This is a flowchart illustrating a channel transmission method according to an embodiment, which may include the following steps:

[0256] In step 1401, the base station sends Radio Resource Control (RRC) parameters. The RRC parameters are used to indicate the maximum number of times the terminal can repeatedly transmit the target Physical Uplink Shared Channel (PUSCH). The maximum number of repeated transmissions is within a preset range. The preset range includes at least a second range and a third range. The upper limit of the second range is 16, and the lower limit of the third range is 17.

[0257] In step 1402, the base station determines the target TDRA table from at least the second TDRA table corresponding to the second interval range and the third TDRA table corresponding to the third interval range.

[0258] In step 1403, the base station sends target RRC signaling to indicate the target TDRA form;

[0259] In step 1404, the base station sends a second DCI.

[0260] The second DCI is used to instruct the terminal to determine the actual number of repeated transmissions of the target PUSCH in the target TDRA table.

[0261] In step 1405, the terminal determines the actual number of repeated transmissions indicated by the second DCI in the target TDRA table.

[0262] In step 1406, the terminal, based on a preset time-domain transmission resource configuration method, skips unavailable time-domain transmission resources from a plurality of sequentially determined time-domain transmission resources and determines the plurality of available uplink time-domain transmission resources until the number of the plurality of available uplink time-domain transmission resources is the same as the actual number of repeated transmissions.

[0263] In this embodiment of the disclosure, unavailable time-domain transmission resources include, but are not limited to, downlink time-domain transmission resources. The method for determining multiple available uplink time-domain transmission resources is the same as that in step 103 above, and will not be repeated here.

[0264] In step 1407, the terminal repeatedly transmits the target PUSCH on the plurality of available uplink time domain resources.

[0265] In the above embodiments, the counting method for the actual number of repeated transmissions is modified, and at least two TDRA tables need to be maintained in the protocol, which increases the actual number of repeated transmissions of PUSCH by the terminal and improves the uplink coverage performance.

[0266] In addition to the two channel transmission schemes mentioned above, this disclosure also provides another channel transmission scheme, as follows:

[0267] The third approach involves modifying the counting method for the actual number of repeated transmissions, keeping the TDRA table unchanged, and automatically expanding the actual number of repeated transmissions on the terminal.

[0268] Let's first introduce the third solution from the terminal side.

[0269] Reference Figure 15 As shown, Figure 15 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0270] In step 1501, the maximum number of retransmissions of the target physical uplink shared channel (PUSCH) is determined.

[0271] In this embodiment of the disclosure, the base station can send the configured maximum number of repeated transmissions to the terminal through RRC parameter configuration.

[0272] In step 1502, in response to the triggering of a preset configuration rule, the extended actual number of repeated transmissions is determined based on the maximum number of repeated transmissions and the preset configuration rule.

[0273] In this embodiment of the disclosure, if the preset configuration rule is not triggered, the terminal can directly use the maximum number of repeated transmissions as the actual number of repeated transmissions without receiving the DCI instruction. If the DCI instruction is received, the terminal can determine the number of repeated transmissions of the PUSCH indicated by the DCI in the existing fourth TDRA table agreed in the protocol. The upper limit of the number of repeated transmissions of the PUSCH included in the fourth TDRA table is 16, and thus obtain the actual number of repeated transmissions.

[0274] The preset configuration rule is used to extend the actual number of repeated transmissions of the target PUSCH. If the terminal determines that the preset configuration rule has been triggered, it needs to extend the actual number of repeated transmissions based on the actual number of repeated transmissions and the preset configuration rule after determining the actual number of repeated transmissions. The extended actual number of repeated transmissions is greater than 16.

[0275] In step 1503, based on the extended actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0276] In this embodiment of the disclosure, the terminal can, based on a preset time-domain transmission resource configuration method, skip unavailable time-domain transmission resources from a plurality of sequentially determined time-domain transmission resources, and determine the plurality of available uplink time-domain transmission resources until the number of the plurality of available uplink time-domain transmission resources is the same as the extended actual number of repeated transmissions. Unavailable time-domain transmission resources include, but are not limited to, downlink time-domain transmission resources.

[0277] In step 1504, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0278] In the above embodiments, the terminal can trigger preset configuration rules to expand the actual number of repeated transmissions, thereby increasing the actual number of repeated transmissions of the PUSCH and improving the uplink coverage performance.

[0279] In one possible implementation, the terminal determines to trigger a preset configuration rule if the maximum number of repeated transmissions indicated by the received Radio Resource Control (RRC) configuration parameters is greater than 16.

[0280] In another possible implementation, the terminal determines to trigger the preset configuration rule upon receiving a specified RRC parameter and / or specified signaling for triggering the preset configuration rule. The specified RRC parameter may be a newly added RRC parameter specifically for triggering the preset configuration rule. The specified signaling may be newly added signaling specifically for triggering the preset configuration rule, including but not limited to MAC (Media Access Control) CE (Control Element) signaling, or DCI.

[0281] In another possible implementation, the terminal determines to trigger the preset configuration rule when the maximum number of repeated transmissions indicated by the received Radio Resource Control (RRC) configuration parameters is greater than 16, and when it receives the specified RRC parameters and / or specified signaling for triggering the preset configuration rule.

[0282] Reference Figure 16 As shown, Figure 16 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0283] In step 1601, the maximum number of retransmissions of the target Physical Uplink Shared Channel (PUSCH) is determined.

[0284] In step 1602, in response to the triggering of a preset configuration rule but the absence of a downlink control signaling (DCI) indicating the actual number of repeated transmissions, the extended actual number of repeated transmissions is determined based on the maximum number of repeated transmissions and the preset configuration rule.

[0285] In this embodiment of the disclosure, if the maximum number of repeated transmissions indicated by the RRC parameter is greater than 16, the terminal may determine to trigger the preset configuration rule, or the terminal may determine to trigger the preset configuration rule upon receiving the specified parameter or specified signaling used to trigger the preset configuration rule.

[0286] Furthermore, if the preset configuration rule is triggered and the maximum number of repeated transmissions of the target PUSCH indicated by the RRC parameter is greater than 16, the terminal can directly use the maximum number of repeated transmissions as the extended actual number of repeated transmissions.

[0287] Alternatively, if a preset configuration rule is triggered and the maximum number of repeated transmissions of the target PUSCH indicated by the RRC parameter is less than or equal to 16, the terminal can use the maximum number of repeated transmissions as the actual number of repeated transmissions, and extend the actual number of repeated transmissions based on the preset rule to obtain the extended actual number of repeated transmissions.

[0288] In this embodiment of the disclosure, the extended actual number of repeated transmissions K' can be the result of a calculation between the actual number of repeated transmissions and a preset configuration rule. The preset rule may include, but is not limited to, a summation operation with a preset value, which can be determined based on the extended actual number of repeated transmissions. Optionally, the extended actual number of repeated transmissions K' can be determined using, but is not limited to, the following formula:

[0289] K' = K + M Formula 1

[0290] Where K' is the actual number of repeated transmissions after expansion, K is the actual number of repeated transmissions, and M is a preset value, which can be 16, 32, 64, etc.

[0291] In step 1603, based on the extended actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0292] In step 1604, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0293] In the above embodiments, the terminal can trigger preset configuration rules to expand the actual number of repeated transmissions, thereby increasing the actual number of repeated transmissions of the PUSCH and improving the uplink coverage performance.

[0294] Reference Figure 17 As shown, Figure 17 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a terminal and may include the following steps:

[0295] In step 1701, the maximum number of retransmissions of the target physical uplink shared channel (PUSCH) is determined.

[0296] In step 1702, in response to the triggering of a preset configuration rule, the actual number of repeated transmissions of the received third DCI indication is determined in the fourth TDRA table.

[0297] In this embodiment of the disclosure, the maximum number of repeated transmissions of PUSCH included in the fourth TDRA table is 16. Optionally, the fourth TDRA table is a TDRA table agreed upon by an existing protocol.

[0298] In step 1703, the extended actual number of repeated transmissions is determined based on the calculated result of the actual number of repeated transmissions indicated by the third DCI and the preset configuration rule.

[0299] In this embodiment of the disclosure, the actual number of repeated transmissions after expansion can be determined using, but is not limited to, Formula 1 above.

[0300] In step 1704, based on the extended actual number of repeated transmissions, multiple available uplink time-domain transmission resources for repeatedly transmitting the target PUSCH are determined.

[0301] In step 1705, the target PUSCH is repeatedly transmitted over the plurality of available uplink time-domain resources.

[0302] In the above embodiments, the terminal can trigger preset configuration rules to expand the actual number of repeated transmissions, thereby increasing the actual number of repeated transmissions of the PUSCH and improving the uplink coverage performance.

[0303] In some optional embodiments, the terminal may report second auxiliary information to the base station. This second auxiliary information assists the base station in determining that the terminal has triggered the preset configuration rule. Optionally, the second auxiliary information may be the same as the first auxiliary information, including but not limited to the decoding performance of the terminal's previous received downlink data and the measurement results of the terminal's measurement of downlink channel reception quality.

[0304] Next, we will introduce the third channel transmission scheme provided in this disclosure from the perspective of the base station. (Refer to...) Figure 18 As shown, Figure 18 This is a flowchart illustrating a channel transmission method according to an embodiment. The method is used in a base station and may include the following steps:

[0305] In step 1801, in response to the need to trigger a preset configuration rule, a target radio resource control (RRC) parameter or target signaling is sent to trigger the preset configuration rule. The preset configuration rule is used by the terminal to extend the actual number of repeated transmissions of the target physical uplink shared channel (PUSCH).

[0306] In this embodiment of the disclosure, the base station may determine the need to trigger a preset configuration rule using, but is not limited to, the following methods.

[0307] In one possible implementation, the base station can determine the need to trigger a preset configuration rule based on the network-side coverage enhancement target.

[0308] In another possible implementation, the base station can determine whether a preset configuration rule needs to be triggered based on the measurement results of the uplink channel reception quality.

[0309] In another possible implementation, the base station can determine whether to trigger a preset configuration rule based on the second auxiliary information reported by the terminal. This second auxiliary information may include, but is not limited to, the decoding performance of the terminal's previous received downlink data and the measurement results of the terminal's measurement of the downlink channel reception quality.

[0310] In this embodiment of the disclosure, the target RRC parameter sent by the base station can use existing RRC parameters to trigger preset configuration rules on the terminal side. Optionally, the target RRC parameter includes an RRC parameter used to indicate the maximum number of repeated transmissions of the target PUSCH by the terminal, including but not limited to the pusch-AggregationFactor. Alternatively, the target RRC parameter sent by the base station can use a newly added specified RRC parameter specifically used to trigger preset configuration rules.

[0311] The target signaling sent by the base station may include, but is not limited to, the specified signaling used to trigger the preset configuration rule. The specified signaling may include, but is not limited to, MAC CE signaling and DCI.

[0312] In the above embodiments, the base station can trigger a preset configuration rule through the target RRC parameter or target signaling. The terminal can extend the actual number of repeated transmissions of the target PUSCH based on the preset configuration rule, which also increases the actual number of repeated transmissions of the PUSCH and improves the uplink coverage performance.
