Abstract

This disclosure relates to the field of communication technology, specifically to channel reception and transmission methods and apparatus, communication devices, and storage media. The channel reception method includes: determining a pattern for retransmitting a Physical Downlink Shared Channel (PDSCH), wherein a first time-domain resource in the pattern for retransmitting the PDSCH does not overlap with a second time-domain resource occupied by an uplink subband configured for a terminal; and receiving the PDSCH retransmitted by a network device according to the pattern. According to this disclosure, since the first time-domain resource indicated by the pattern does not overlap with the second time-domain resource occupied by the uplink subband configured for the terminal, the overlap between the time-domain resources for retransmitted PDSCH and the downlink time slots configured with uplink subbands can be avoided.

[0037] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0038] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. The singular forms “a” 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.

[0039] It should be understood that although the terms first, second, third, etc., may be used to describe various information in embodiments of this disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, first information may also be referred to as second information without departing from the scope of embodiments of this disclosure, 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 a determination."

[0040] For the sake of brevity and ease of understanding, this document uses the terms "greater than" or "less than", "higher than" or "lower than" to describe size relationships. However, it will be understood by those skilled in the art that the term "greater than" also includes the meaning of "greater than or equal to", and "less than" also includes the meaning of "less than or equal to"; the term "higher than" also includes the meaning of "higher than or equal to", and "lower than" also includes the meaning of "lower than or equal to".

[0041] In one embodiment, the network device can configure an uplink subband for the terminal using downlink time domain resources. If the network device is capable of full-duplex communication and the terminal is capable of half-duplex communication, the terminal can perform uplink communication within the uplink subband or downlink communication on frequency domain resources outside the uplink subband in the downlink time domain unit. If both the network device and the terminal are capable of full-duplex communication, the terminal can perform uplink communication within the uplink subband and downlink communication on frequency domain resources outside the uplink subband in the downlink time domain unit.

[0042] In one embodiment, time-domain resources include at least one of the following: slots and symbols, for example, symbols may be orthogonal frequency division multiplexing (OFDM) symbols.

[0043] In one embodiment, for reasons such as coverage enhancement (CE) or to improve time-domain diversity gain, the network device may repeatedly transmit the Physical Downlink Shared Channel (PHSDC) sent to the terminal.

[0044] However, PDSCH can only be repeatedly transmitted on consecutive time slots. When the time domain resources of a PDSCH in a repeated transmission overlap with a symbol configured with an uplink subband, that PDSCH needs to be dropped, which will affect the performance of repeated PDSCH transmission.

[0045] Figure 1 This is a schematic flowchart illustrating a channel receiving method according to an embodiment of the present disclosure. The channel receiving method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core network equipment.

[0046] like Figure 1 As shown, the channel receiving method may include the following steps:

[0047] In step S101, a pattern for retransmitting the physical downlink shared channel is determined, wherein the first time domain resource for retransmitting the physical downlink shared channel in the pattern does not overlap with the second time domain resource occupied by the uplink subband configured for the terminal;

[0048] In step S102, the physical downlink shared channel repeatedly transmitted by the network device is received according to the pattern.

[0049] In one embodiment, for example, if the network device configures an uplink subband for the terminal in at least one time slot in a subframe, then the at least one time slot where the uplink subband is located is the second time domain resource occupied by the uplink subband; for example, if the network device configures an uplink subband for the terminal in at least one symbol in a time slot, then the at least one symbol where the uplink subband is located is the second time domain resource occupied by the uplink subband.

[0050] In one embodiment, the terminal may determine a pattern of repeatedly transmitted PDSCH, wherein the pattern may indicate a first time-domain resource occupied by the PDSCH.

[0051] Therefore, by ensuring that the first time domain resource indicated by the diagram does not overlap with the second time domain resource occupied by the uplink subband configured for the terminal, the time domain resource of the repeatedly transmitted PDSCH can be avoided from overlapping with the downlink time slot configured with the uplink subband, thereby avoiding the discarding of a certain repeatedly transmitted PDSCH and improving the performance of repeatedly transmitted PDSCH.

[0052] Figure 2 This is a schematic diagram illustrating several uplink subbands according to embodiments of the present disclosure.

[0053] Network devices can configure uplink subbands for terminals in downlink time slots, taking as an example the frequency domain resources corresponding to the downlink time slot including a bandwidth part (BWP).

[0054] In one embodiment, such as Figure 2 As shown in the left time slot, in the downlink time slot, the frequency domain resources (uplink resources) corresponding to the uplink subband do not overlap with the frequency domain resources (downlink resources) used for downlink reception;

[0055] In one embodiment, such as Figure 2 As shown in the intermediate time slot, in the downlink time slot, the frequency domain resources (uplink resources) corresponding to the uplink subband completely overlap with the frequency domain resources (downlink resources) used for downlink reception;

[0056] In one embodiment, such as Figure 2 As shown in the right-hand time slot, in the downlink time slot, the frequency domain resources (uplink resources) corresponding to the uplink subband partially overlap with the frequency domain resources (downlink resources) used for downlink reception.

[0057] The following examples illustrate the case where the frequency domain resources (uplink resources) corresponding to the uplink subband in the downlink time slot do not overlap with the frequency domain resources (downlink resources) used for downlink reception.

[0058] Figure 3 This is a schematic flowchart illustrating another channel receiving method according to embodiments of the present disclosure. Figure 3 The method shown can be executed by a terminal, such as Figure 3 As shown, the pattern used to determine the physical downlink shared channel for repeated transmission includes:

[0059] In step S301, the pattern is determined based on the first instruction information sent by the network device.

[0060] It should be noted that, Figure 3The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not impose any restrictions.

[0061] In one embodiment, the network device may send first indication information to the terminal, indicating a pattern through the first indication information. Correspondingly, the terminal can determine the pattern based on the first indication information sent by the network device.

[0062] In one embodiment, the pattern includes at least one of the following:

[0063] The duration of each transmission in n+1 consecutive repeated transmissions;

[0064] The interval (gap) between two consecutive repeated transmissions in n+1 consecutive transmissions.

[0065] Where n is an integer greater than or equal to 1.

[0066] It should be noted that the interval can be greater than 0 time slot units (e.g., time slot / symbol) or equal to 0. When the interval is equal to 0, there is no interval. In n+1 consecutive repeated transmissions, the duration of each repeated transmission includes n+1 durations, and each duration can be equal or unequal.

[0067] In one embodiment, a PDSCH retransmission is performed once in a time slot, and the sum of the number of time slots included in the duration of each retransmission in n+1 consecutive retransmissions is equal to the number of times the physical downlink shared channel is retransmitted; and / or the sum of the intervals between two adjacent retransmissions in n+1 consecutive retransmissions is equal to the second time domain resource.

[0068] In one embodiment, the pattern can indicate the interval between two adjacent repetitive transmissions in n+1 consecutive repetitive transmissions. Since the sum of the intervals between two adjacent repetitive transmissions in n+1 consecutive repetitive transmissions is equal to the second time domain resource, which is also equal to the time domain resource occupied by the uplink subband, the terminal can ensure that the repetitive transmission PDSCH does not overlap with the time domain resource occupied by the uplink subband by receiving the PDSCH based on the interval between two adjacent repetitive transmissions in n+1 consecutive repetitive transmissions in the pattern.

[0069] In one embodiment, the pattern may also indicate the duration of each repetition in n+1 consecutive repetitions. Since the sum of the number of time slots included in the duration of each repetition in n+1 consecutive repetitions is equal to the number of times the PDSCH is repetitively transmitted, and only one PDSCH repetition is performed in a time slot, the terminal can ensure that the number of times the PDSCH is received is equal to the number of times the PDSCH is repetitively transmitted by receiving the repetitive PDSCH based on the duration of each repetition in n+1 consecutive repetitions in the pattern.

[0070] In one embodiment, the first indication information may be, or be carried in, at least one of the following signaling:

[0071] Broadcast signaling, such as System Information Blocks (SIBs), such as SIB1;

[0072] Radio Resource Control (RRC) signaling;

[0073] Physical layer signaling, such as downlink control information (DCI).

[0074] Figure 4A This is a schematic diagram illustrating a time slot structure and uplink subband according to an embodiment of the present disclosure. Figure 4B This is a schematic diagram illustrating the relationship between a first time-domain resource and a second time-domain resource according to an embodiment of the present disclosure.

[0075] For example, network devices configure terminals with a type such as Figure 4A The Time Division Duplex (TDD) time slot structure shown is DDDDDDDFUU. Here, "D" represents downlink time slots, "F" represents flexible time slots, and "U" represents uplink time slots. That is, slots #0 to #6 are downlink time slots, slot #7 is a flexible time slot, and slots #8 and #9 are uplink time slots. The network device configures uplink subbands for the terminals in downlink time slots #2 to #4.

[0076] Additionally, the terminal can determine the number of PDSCH retransmissions, for example, four times, with only one PDSCH retransmission per time slot, and determine the starting position of the retransmission, for example, slot #0. Then, from slot #0 to slot #3, four consecutive PDSCH retransmissions can be performed. However, uplink subbands are configured on slots #2 and #3, so the time domain resources for retransmitting PDSCH overlap with the downlink time slots where the uplink subbands are located. Therefore, the PDSCH retransmitted on slots #2 and #3 will be discarded, resulting in only two actual PDSCH retransmissions, instead of four, thus affecting the performance of the retransmitted PDSCH.

[0077] like Figure 4B As shown, according to an embodiment of this disclosure, a network device can send first indication information to a terminal, indicating a pattern through the first indication information. For example, the n intervals indicated by the pattern include one interval and two durations, wherein one interval consists of three time slots, and the two durations each consist of two time slots.

[0078] According to the pattern indicated by the first indication information, starting from slot #0, the terminal can continuously receive repeatedly transmitted PDSCH for two time slots (slot #0 to slot #1), then stop receiving repeatedly transmitted PDSCH for three time slots (slot #2 to slot #4), and then continuously receive repeatedly transmitted PDSCH for two time slots (slot #5 to slot #6). This ensures that the number of times repeatedly transmitted PDSCH is received is four, and that the time domain resources for receiving repeatedly transmitted PDSCH do not overlap with the downlink time slots configured with uplink subbands. This ensures the performance of repeatedly transmitted PDSCH.

[0079] Figure 5 This is a schematic flowchart illustrating another channel receiving method according to embodiments of the present disclosure. Figure 5 The method shown can be executed by a terminal, such as Figure 5 As shown, the pattern determined based on the first instruction information sent by the network device includes:

[0080] In step S501, multiple first patterns are determined based on information in broadcast signaling or radio resource control signaling;

[0081] In step S502, a second pattern is determined from multiple first patterns based on information in the physical layer signaling.

[0082] It should be noted that, Figure 5 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not impose any restrictions.

[0083] In one embodiment, the first indication information may include information from broadcast signaling or radio resource control signaling and information from physical layer signaling. The information from the broadcast signaling or radio resource control signaling is used to indicate multiple first patterns; the information from the physical layer signaling, for example, carried in DCI, is used to indicate a second pattern among the multiple first patterns.

[0084] After receiving broadcast signaling or RRC signaling, the terminal can obtain information from it and then determine multiple first patterns based on the information. Then, it obtains information from the received DCI and then determines a second pattern from the multiple first patterns based on the information, and determines the first time domain resource for repeated transmission of PDSCH based on the second pattern.

[0085] For example, a network device carries information in RRC signaling, indicating two patterns: pattern #1 and pattern #2. Pattern #1 indicates repeated transmission of PDSCH in consecutive time slots, while pattern #2 indicates one interval and two durations, with the interval consisting of three time slots and each duration consisting of two time slots. Subsequent network devices can carry a second indication in DCI to indicate either pattern #1 or pattern #2; let's take pattern #2 as an example.

[0086] After receiving the RRC signaling, the terminal can determine pattern#1 and pattern#2 based on the information in the RRC signaling. Subsequently, when receiving the DCI, it can determine pattern#2 based on the information in the DCI from pattern#1 and pattern#2, and then determine the first time domain resource for repeated transmission of PDSCH based on pattern#2.

[0087] In one embodiment, the channel receiving method further includes:

[0088] The number of times the physical downlink shared channel is repeatedly transmitted is determined based on the second instruction information sent by the network device; and / or the number of times the physical downlink shared channel is repeatedly transmitted is determined based on the pattern.

[0089] In one embodiment, the terminal can determine the number of times the PDSCH is repeatedly transmitted. For example, the terminal can determine the number of times the PDSCH is repeatedly transmitted based on a pattern, such as the number of time slots contained in a duration in the pattern. For example, if the pattern contains two durations, and each duration contains two time slots, then there are a total of four time slots. Since each time slot can transmit the PDSCH once, the number of times the PDSCH is repeatedly transmitted can be determined to be 4 based on the four time slots.

[0090] In one embodiment, the terminal can determine the number of times the PDSCH needs to be repeatedly transmitted based on second indication information sent by the network device. The second indication information includes at least one of the following:

[0091] The information element pdsch-AggregationFactor in semi-static configuration signaling;

[0092] The repetition number in the Time Domain Resource Allocation Table (TDRA table).

[0093] The above embodiments mainly describe the situation where the network device instructs the terminal to indicate a pattern through the first instruction information. However, the determination of the pattern is not limited to the network device's instruction; it can also be determined autonomously by the terminal.

[0094] It should be understood that when the terminal determines the pattern autonomously, the network device can also determine the pattern autonomously, and the way the terminal determines the pattern autonomously is the same as the way the network device determines the pattern autonomously. Therefore, it can be guaranteed that the pattern determined by the terminal is the same as the pattern determined by the network device.

[0095] The following examples illustrate how the terminal autonomously determines the pattern.

[0096] Figure 6 This is a schematic flowchart illustrating another channel receiving method according to embodiments of the present disclosure. Figure 6 The method shown can be executed by a terminal, such as Figure 6 As shown, the pattern used to determine the physical downlink shared channel for repeated transmission includes:

[0097] In step S601, it is determined that the first time-domain resource of the repeated transmission physical downlink shared channel overlaps with a first number of time-domain units in the second time-domain resource;

[0098] In step S602, a first number of time-domain units are determined outside the second time-domain resource;

[0099] In step S603, a pattern is determined based on a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource and a first number of time-domain units.

[0100] It should be noted that, Figure 6 The embodiments shown can be implemented independently or in combination with at least one other embodiment of this disclosure. The specific choice can be made as needed, and this disclosure does not impose any restrictions.

[0101] In one embodiment, the terminal can determine the first time-domain resource for repeated PDSCH transmission, for example, based on the start position of the repeated PDSCH transmission and the number of times the PDSCH is repeated.

[0102] Furthermore, the terminal can determine the second time-domain resource occupied by the uplink subband configured for the terminal, and determine whether the second time-domain resource overlaps with the first time-domain resource. If the second time-domain resource overlaps with the first time-domain resource, a first number of overlapping time-domain units in the first and second time-domain resources can be determined. Here, a time-domain unit can be a time slot or a symbol; the following explanation primarily focuses on the case where the time-domain unit is a time slot.

[0103] Since the first time-domain resource and the second time-domain resource overlap by a first number of time-domain units, these overlapping time-domain units cannot be used for repeated PDSCH transmission. Therefore, it is necessary to find a first number of time-domain units that do not overlap with the second time-domain resource for repeated PDSCH transmission. For example, the first number of time-domain units can be determined outside the second time-domain resource, or in the time-domain resource between the second and the nearest time-domain resource. Since the time-domain units outside the second time-domain resource do not overlap with the second time-domain resource, they can be considered as available time-domain units for repeated PDSCH transmission.

[0104] Furthermore, the terminal can determine a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource, and then determine a pattern based on the second number of time-domain units and the first number of time-domain units. Since a PDSCH transmission is performed once in a time slot, it can be ensured that the first time-domain resource indicated by the determined pattern for repeated PDSCH transmission meets the requirement of repeated transmission number and does not overlap with the second time-domain resource.

[0105] Figure 7 This is a schematic diagram illustrating a first number of time-domain units and a second number of time-domain units according to embodiments of the present disclosure.

[0106] like Figure 7 As shown, still in Figure 4A Taking the TDD timeslot structure and uplink subband as an example, if the starting position of the repeated PDSCH transmission is slot#0 and the number of repeated PDSCH transmissions is 4, the terminal can determine that the first time domain resources are slot#0 to slot#3.

[0107] Furthermore, the terminal can determine that the second time domain resources occupied by the uplink subband configured for the terminal are slots #2 to #4, and determine that the first time domain resources slots #0 to #3 overlap with the second time domain resources slots #2 to #4. Specifically, the two time slots slots #2 and slot #3 overlap, and the first number of overlapping time slots is 2.

[0108] Since the first and second time-domain resources overlap in slots #1 and #2, these two slots cannot be used for repeated PDSCH transmission. Therefore, two time slots can be determined from the time-domain resource following the second time-domain resource to the nearest time-domain resource. Since the two time slots following the second time-domain resource to the nearest time-domain resource do not overlap with the second time-domain resource, they can be used as available time-domain units for repeated PDSCH transmission.

[0109] Furthermore, a second number of time-domain units that do not overlap with the second time-domain resource in the first time-domain resource can be determined, namely slots #0 and #1. Then, the pattern can be determined based on the second number of time-domain units and the first number of time-domain units.

[0110] The determined pattern may contain the same content as in the previous embodiment, that is, the pattern includes at least one of the following: the duration of each repeated transmission in n+1 consecutive repeated transmissions; the interval between two adjacent repeated transmissions in n+1 consecutive repeated transmissions; where n is an integer greater than or equal to 1. In one embodiment, the sum of the number of time slots included in the duration of each repeated transmission in n+1 consecutive repeated transmissions is equal to the number of times the physical downlink shared channel is repeated; and / or the sum of the intervals between two adjacent repeated transmissions in n+1 consecutive repeated transmissions is equal to the second time-domain resource.

[0111] Alternatively, the content of the determined pattern can be the same as in the previous embodiment. For example, the determined pattern may be a specific time slot used for repeated transmission, such as slot#0, slot#1, slot#5, and slot#6.

[0112] Therefore, the first time-domain resource for repeated transmission of PDSCH is determined according to the determined pattern, and there is no overlap between it and the second time-domain resource, and the number of repeated transmissions can still be satisfied as 4 times.

[0113] In one embodiment, the channel receiving method further includes: determining the number of times the physical downlink shared channel is repeatedly transmitted based on second indication information sent by the network device.

[0114] Because in Figure 6Based on the illustrated embodiment, the terminal does not receive a pattern from the network device. Therefore, the terminal can determine the number of times the PDSCH is repeatedly transmitted based on the second indication information sent by the network device. The second indication information includes at least one of the following: the pdsch-AggregationFactor information element in the semi-static configuration signaling; or the repetition number in the TDRA table.

[0115] Figure 8 This is a schematic flowchart illustrating a channel transmission method according to an embodiment of the present disclosure. The channel transmission method shown in this embodiment can be executed by a network device, which can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0116] like Figure 8 As shown, the channel transmission method may include the following steps:

[0117] In step S801, a pattern for repeated transmission of the physical downlink shared channel is determined, wherein the first time domain resource for repeated transmission of the physical downlink shared channel in the pattern does not overlap with the second time domain resource occupied by the uplink subband configured for the terminal;

[0118] In step S802, the physical downlink shared channel is repeatedly transmitted to the terminal according to the pattern.

[0119] In one embodiment, the network device can determine a pattern of repeatedly transmitted PDSCH, wherein the pattern can indicate a first time-domain resource occupied by the PDSCH.

[0120] Since the first time domain resource indicated by the diagram does not overlap with the second time domain resource occupied by the uplink subband configured for the terminal, the time domain resource of the repeatedly transmitted PDSCH can be avoided from overlapping with the downlink time slot configured with the uplink subband. Therefore, when the network device transmits the PDSCH repeatedly, it does not need to discard a certain repeatedly transmitted PDSCH, thus ensuring the performance of the repeatedly transmitted PDSCH.

[0121] In one embodiment, the channel transmission method further includes: sending first indication information to the terminal, wherein the first indication information is used to indicate a pattern.

[0122] In one embodiment, the network device may send first indication information to the terminal, indicating a pattern through the first indication information. Correspondingly, the terminal can determine the pattern based on the first indication information sent by the network device.

[0123] In one embodiment, the pattern includes at least one of the following: the duration of each repeated transmission in n+1 consecutive repeated transmissions; the interval between two adjacent repeated transmissions in n+1 consecutive repeated transmissions; where n is an integer greater than or equal to 1. It should be noted that the interval can be greater than 0 or equal to 0; if the interval is equal to 0, there is no interval.

[0124] In one embodiment, the duration of each repeated transmission in n+1 consecutive repeated transmissions is equal to the first time-domain resource of the physical downlink shared channel for repeated transmissions; and / or the sum of the intervals between two adjacent repeated transmissions in n+1 consecutive repeated transmissions is equal to the second time-domain resource.

[0125] In one embodiment, the pattern can indicate the interval between two adjacent repetitive transmissions in n+1 consecutive repetitive transmissions. Since the sum of the intervals between two adjacent repetitive transmissions in n+1 consecutive repetitive transmissions is equal to the second time domain resource, which is also equal to the time domain resource occupied by the uplink subband, the terminal can ensure that the repetitive transmission PDSCH does not overlap with the time domain resource occupied by the uplink subband by receiving the PDSCH based on the interval between two adjacent repetitive transmissions in n+1 consecutive repetitive transmissions in the pattern.

[0126] In one embodiment, the pattern may also indicate the duration of each repetition in n+1 consecutive repetitions. Since the sum of the number of time slots included in the duration of each repetition in n+1 consecutive repetitions is equal to the number of times the PDSCH is repetitively transmitted, and only one PDSCH repetition is performed in a time slot, the terminal can ensure that the number of times the PDSCH is received is equal to the number of times the PDSCH is repetitively transmitted by receiving the repetitive PDSCH based on the duration of each repetition in n+1 consecutive repetitions in the pattern.

[0127] In one embodiment, the first indication information may be, or be carried in, at least one of the following signaling: broadcast signaling; radio resource control signaling; physical layer signaling.

[0128] In one embodiment, sending the first indication information to the terminal includes:

[0129] In sending broadcast signaling or radio resource control signaling to the terminal, the information in the broadcast signaling or radio resource control signaling is used to indicate multiple first patterns;

[0130] In sending physical layer signaling to the terminal, the information in the physical layer signaling is used to indicate a second pattern among multiple first patterns.

[0131] In one embodiment, the first indication information may include broadcast signaling or radio resource control (RRC) signaling information and information in physical layer signaling. The information in the broadcast signaling or RRC signaling is used to indicate multiple first patterns; the information in the physical layer signaling, for example, carried in the DCI, is used to indicate a second pattern among the multiple first patterns.

[0132] After receiving broadcast signaling or RRC signaling, the terminal can obtain information from it and then determine multiple first patterns based on the information. Then, it obtains information from the received DCI and then determines a second pattern from the multiple first patterns based on the information, and determines the first time domain resource for repeated transmission of PDSCH based on the second pattern.

[0133] For example, a network device carries information in RRC signaling, indicating two patterns: pattern #1 and pattern #2. Pattern #1 indicates repeated transmission of PDSCH in consecutive time slots, while pattern #2 indicates one interval and two durations, with the interval consisting of three time slots and each duration consisting of two time slots. Subsequent network devices can carry a second indication in DCI to indicate either pattern #1 or pattern #2; let's take pattern #2 as an example.

[0134] After receiving the RRC signaling, the terminal can determine pattern#1 and pattern#2 based on the information in the RRC signaling. Subsequently, when receiving the DCI, it can determine pattern#2 based on the information in the DCI from pattern#1 and pattern#2, and then determine the first time domain resource for repeated transmission of PDSCH based on pattern#2.

[0135] In one embodiment, the channel transmission method further includes: sending second indication information to a terminal, wherein the second indication information is used to indicate the number of times the physical downlink shared channel is transmitted; and / or indicating to the terminal the number of times the physical downlink shared channel is repeatedly transmitted via a pattern.

[0136] In one embodiment, the network device can indicate to the terminal the number of times the PDSCH will be repeatedly transmitted. For example, the network device can indicate the number of times the PDSCH will be repeatedly transmitted through a pattern, such as the number of time slots included in the duration of the pattern. For example, if the pattern contains two durations, each duration contains two time slots, then there are a total of four time slots. Since each time slot can transmit the PDSCH once, the number of times the PDSCH will be repeatedly transmitted can be indicated as four based on the four time slots.

[0137] In one embodiment, the network device can indicate the number of times the PDSCH should be repeatedly transmitted by sending a second indication message to the terminal. The second indication message includes at least one of the following:

[0138] The information element pdsch-AggregationFactor in semi-static configuration signaling;

[0139] The repetition number in the Time Domain Resource Allocation Table (TDRA table).

[0140] In one embodiment, determining a pattern for retransmitting a physical downlink shared channel includes: determining that a first time-domain resource of the retransmitted physical downlink shared channel overlaps with a first number of time-domain units in a second time-domain resource; determining a first number of time-domain units outside the second time-domain resource; and determining a pattern based on a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource and the first number of time-domain units.

[0141] In one embodiment, the network device can determine a first time-domain resource for repeated PDSCH transmissions, for example, based on the start position of the repeated PDSCH transmissions and the number of times the PDSCH is repeated.

[0142] Furthermore, the network device can determine the second time-domain resources occupied by the uplink subband configured for the terminal, and determine whether the second time-domain resources overlap with the first time-domain resources. If the second time-domain resources overlap with the first time-domain resources, a first number of overlapping time-domain units in the first and second time-domain resources can be determined. Here, a time-domain unit can be a time slot or a symbol; the following explanation primarily focuses on the case where the time-domain unit is a time slot.

[0143] Since the first time-domain resource and the second time-domain resource overlap by a first number of time-domain units, these overlapping time-domain units cannot be used for repeated PDSCH transmission. Therefore, it is necessary to find a first number of time-domain units that do not overlap with the second time-domain resource for repeated PDSCH transmission. For example, the first number of time-domain units can be determined outside the second time-domain resource, or in the time-domain resource between the second and the nearest time-domain resource. Since the time-domain units outside the second time-domain resource do not overlap with the second time-domain resource, they can be considered as available time-domain units for repeated PDSCH transmission.

[0144] Furthermore, the network device can determine a second number of time-domain elements in the first time-domain resource that do not overlap with the second time-domain resource, and then determine a pattern based on the second number of time-domain elements and the first number of time-domain elements. Since a PDSCH transmission is performed once in a time slot, it can be ensured that the first time-domain resource indicated by the determined pattern for repeated PDSCH transmission meets the requirement of repeated transmission number and does not overlap with the second time-domain resource.

[0145] In one embodiment, the channel transmission method further includes: sending second indication information to the terminal, wherein the second indication information is used to indicate the number of times the physical downlink shared channel is used.

[0146] Without sending a pattern to the terminal, the network device can indicate the number of times the PDSCH will be repeatedly transmitted by sending a second indication message. This second indication message includes at least one of the following: the pdsch-AggregationFactor information element in the semi-static configuration signaling; or the repetition number in the TDRA table.

[0147] Figure 9 This is a schematic flowchart illustrating a channel receiving method according to an embodiment of the present disclosure. The channel receiving method shown in this embodiment can be executed by a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices. The terminal can communicate with network devices, which include, but are not limited to, network devices in 4G, 5G, and 6G communication systems, such as base stations and core network equipment.

[0148] like Figure 9 As shown, the channel receiving method includes:

[0149] In step S901, it is determined that the first time domain resource of the repeated transmission physical downlink shared channel overlaps with a first number of time domain units in the second time domain resource occupied by the uplink subband configured for the terminal;

[0150] In step S902, the first number of time-domain units are determined outside the second time-domain resource;

[0151] In step S903, the physical downlink shared channel repeatedly transmitted by the network device is received in a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource, and in the first number of time-domain units.

[0152] In one embodiment, the terminal can determine the first time-domain resource for repeated PDSCH transmission, for example, based on the start position of the repeated PDSCH transmission and the number of times the PDSCH is repeated.

[0153] Furthermore, the terminal can determine the second time-domain resource occupied by the uplink subband configured for the terminal, and determine whether the second time-domain resource overlaps with the first time-domain resource. If the second time-domain resource overlaps with the first time-domain resource, a first number of overlapping time-domain units in the first and second time-domain resources can be determined. Here, a time-domain unit can be a time slot or a symbol; the following explanation primarily focuses on the case where the time-domain unit is a time slot.

[0154] Since the first time-domain resource and the second time-domain resource overlap by a first number of time-domain units, these overlapping time-domain units cannot be used for repeated PDSCH transmission. Therefore, it is necessary to find a first number of time-domain units that do not overlap with the second time-domain resource for repeated PDSCH transmission. For example, the first number of time-domain units can be determined outside the second time-domain resource, or in the time-domain resource between the second and the nearest time-domain resource. Since the time-domain units outside the second time-domain resource do not overlap with the second time-domain resource, they can be considered as available time-domain units for repeated PDSCH transmission.

[0155] Furthermore, the terminal can determine a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource, and then receive the Physical Downlink Shared Channel (PDSCH) repeatedly transmitted by the network device in the second number of time-domain units and the first number of time-domain units. Since PDSCH is transmitted once in a time slot, it can be ensured that the first time-domain resource indicated by the determined pattern for repeated PDSCH transmission meets the requirement of repeated transmission number and does not overlap with the second time-domain resource.

[0156] Figure 10 This is a schematic flowchart illustrating a channel transmission method according to an embodiment of the present disclosure. The channel transmission method shown in this embodiment can be executed by a network device, which can communicate with a terminal. The network device includes, but is not limited to, base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. The terminal includes, but is not limited to, communication devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0157] like Figure 10 As shown, the channel transmission method includes:

[0158] In step S1001, it is determined that the first time domain resource of the repeated transmission physical downlink shared channel overlaps with a first number of time domain units in the second time domain resource occupied by the uplink subband configured for the terminal;

[0159] In step S1002, the first number of time-domain units are determined outside the second time-domain resource;

[0160] In step S1003, the physical downlink shared channel is repeatedly transmitted to the terminal by a second number of time-domain units that do not overlap with the second time-domain resource in the first time-domain resource, and the first number of time-domain units.

[0161] In one embodiment, the network device can determine a first time-domain resource for repeated PDSCH transmissions, for example, based on the start position of the repeated PDSCH transmissions and the number of times the PDSCH is repeated.

[0162] Furthermore, the network device can determine the second time-domain resources occupied by the uplink subband configured for the terminal, and determine whether the second time-domain resources overlap with the first time-domain resources. If the second time-domain resources overlap with the first time-domain resources, a first number of overlapping time-domain units in the first and second time-domain resources can be determined. Here, a time-domain unit can be a time slot or a symbol; the following explanation primarily focuses on the case where the time-domain unit is a time slot.

[0163] Since the first time-domain resource and the second time-domain resource overlap by a first number of time-domain units, these overlapping time-domain units cannot be used for repeated PDSCH transmission. Therefore, it is necessary to find a first number of time-domain units that do not overlap with the second time-domain resource for repeated PDSCH transmission. For example, the first number of time-domain units can be determined outside the second time-domain resource, or in the time-domain resource between the second and the nearest time-domain resource. Since the time-domain units outside the second time-domain resource do not overlap with the second time-domain resource, they can be considered as available time-domain units for repeated PDSCH transmission.

[0164] Furthermore, the network device can determine a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource, and then repeatedly transmit the Physical Downlink Shared Channel to the terminal in the second number of time-domain units and the first number of time-domain units. Since PDSCH transmission is performed once in a time slot, it can be ensured that the first time-domain resource indicated by the determined pattern for repeated PDSCH transmission meets the requirement of repeated transmission number on the one hand, and does not overlap with the second time-domain resource on the other hand.

[0165] Figure 11 This is a schematic diagram illustrating the interaction between a terminal and a network device according to an embodiment of the present disclosure.

[0166] like Figure 11 As shown, the terminal can determine the pattern used for repeated PDSCH transmission. The first time domain resources occupied by the repeated PDSCH indicated by the pattern do not overlap with the second time domain resources occupied by the uplink subband configured for the terminal. Therefore, the terminal can receive the repeatedly transmitted PDSCH from the network device according to the pattern.

[0167] Correspondingly, the network device can also determine a pattern for retransmitting the PDSCH, wherein the first time domain resources occupied by the pattern for retransmitting the PDSCH do not overlap with the second time domain resources occupied by the uplink subband configured for the terminal. Therefore, the network device can retransmit the PDSCH to the terminal according to the pattern.

[0168] In one embodiment, the network device may send first indication information to the terminal, wherein the first indication information is used to indicate a pattern. The terminal can determine the pattern based on the first indication information sent by the network device.

[0169] For example, the first instruction information may be at least one of the following signaling, or carried in at least one of the following signaling: broadcast signaling; RRC signaling; DCI.

[0170] In one embodiment, the pattern includes at least one of the following: the duration of each repetition in n+1 consecutive repetitions; the interval between two adjacent repetitions in n+1 consecutive repetitions; where n is an integer greater than or equal to 1. For example, the sum of the number of time slots included in the duration of each repetition in n+1 consecutive repetitions is equal to the number of times the physical downlink shared channel is repetitively transmitted; for example, the sum of the intervals between two adjacent repetitions in n+1 consecutive repetitions is equal to a second time-domain resource.

[0171] In one embodiment, the terminal and network device can each autonomously determine the pattern in the same manner.

[0172] For example, firstly, it is determined that a first time-domain resource for repeated PDSCH transmission overlaps with a first number of time-domain units in a second time-domain resource; then, a first number of time-domain units are determined outside the second time-domain resource; finally, a pattern is determined based on a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource and the first number of time-domain units.

[0173] Since the first time-domain resource and the second time-domain resource overlap by a first number of time-domain units, these overlapping time-domain units cannot be used for repeated PDSCH transmission. Therefore, it is necessary to find a first number of time-domain units that do not overlap with the second time-domain resource for repeated PDSCH transmission. For example, the first number of time-domain units can be determined outside the second time-domain resource, or in the time-domain resource between the second and the nearest time-domain resource. Since the time-domain units outside the second time-domain resource do not overlap with the second time-domain resource, they can be considered as available time-domain units for repeated PDSCH transmission.

[0174] Furthermore, a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource can be determined, and then a pattern can be determined based on the second number of time-domain units and the first number of time-domain units. Since a PDSCH transmission is performed once in a time slot, it can be ensured that the first time-domain resource indicated by the determined pattern for repeated PDSCH transmission meets the requirement of the number of repetitions and does not overlap with the second time-domain resource.

[0175] In one embodiment, the terminal and network device can each autonomously determine in the same way which time domain units the PDSCH will be repeatedly transmitted.

[0176] For example, firstly, it is determined that a first time-domain resource for repeated PDSCH transmission overlaps with a first number of time-domain units in a second time-domain resource; then, a first number of time-domain units are determined outside the second time-domain resource; finally, a pattern is determined based on a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource and the first number of time-domain units.

[0177] Since the first time-domain resource and the second time-domain resource overlap by a first number of time-domain units, these overlapping time-domain units cannot be used for repeated PDSCH transmission. Therefore, it is necessary to find a first number of time-domain units that do not overlap with the second time-domain resource for repeated PDSCH transmission. For example, the first number of time-domain units can be determined outside the second time-domain resource, or in the time-domain resource between the second and the nearest time-domain resource. Since the time-domain units outside the second time-domain resource do not overlap with the second time-domain resource, they can be considered as available time-domain units for repeated PDSCH transmission.

[0178] Furthermore, a second number of time-domain units in the first time-domain resource that do not overlap with the second time-domain resource can be determined. The terminal can then receive PDSCH repeatedly transmitted by the network device in both the second and first number of time-domain units. The network device can also repeatedly transmit PDSCH to the terminal in both the second and first number of time-domain units. Since PDSCH transmission occurs only once per time slot, it can be ensured that the first time-domain resource indicated by the determined pattern for repeated PDSCH transmission meets the requirement for the number of repetitions and does not overlap with the second time-domain resource.

[0179] It should be noted that other contents involved in this embodiment are described in the previous embodiments, and will not be repeated here.
