Therefore, the following description is presented for the purposes of illustrative discussion.
[0073] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting.

[0074] It will be understood that, although the terms first, second, third, etc. can be used herein to describe various information, these terms are not intended to denote a temporal or chronological order. Rather, these terms are used only as labels to identify particular information. For example, a first information can be termed a second information, and similarly, a second information can be termed a first information without departing from the scope of the present disclosure. Depending on the context, the word "if' as used herein can be interpreted as meaning "when" or "in response to determining."
[0075] Reference will now be made to Figure 1 which shows a schematic diagram of a system architecture provided by an embodiment of the present application. The system architecture can include a terminal device 10 and a network device 20.
[0076] The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in a cell managed by each network device 20. The terminal device 10 can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication functions, and various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices in the embodiments of the present application.
[0077] The network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The network device 20 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different, for example, in a 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name of "network device" may change. For the convenience of description, the above-mentioned devices providing wireless communication functions for the terminal device 10 are collectively referred to as network devices in the embodiments of the present application.
[0078] For example, a network device 20 is deployed with multiple TRPs, for example, the network device 20 corresponds to TRP1, TRP2, …, TRPn. The terminal device uses different transmission beams to face different TRPs for repeated transmission of the uplink channel, and the network device 20 receives the repeated transmission of the uplink channel sent by the terminal device through multiple TRPs. For example, because the relative positions of different TRPs and the terminal device are different, the terminal device needs to use transmission beams with different beam directions to send beams to the TRP in the corresponding direction for repeated transmission of the uplink channel.
[0079] The "5G NR system" in the embodiments of the present disclosure can also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present disclosure can be applied to the 5G NR system, and can also be applied to the subsequent evolution system of the 5G NR system.
[0080] Please refer to Figure 2 , which shows a flowchart of an uplink channel transmission method provided by an embodiment of the present application. The method can be applied in Figure 1 The system architecture shown. The method includes the following steps.
[0081] Step 220, the terminal device performs adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0082] The two adjacent repeated transmissions are transmitted by using different transmission beams to face different TRPs of the same base station (network device), and the time domain resources of the first transmission resource and the second transmission resource have a beam switching time for switching the beam direction; the first transmission resource corresponds to a transmission occasion in front of two adjacent transmission occasions for uplink channel transmission; and the second transmission resource corresponds to a transmission occasion in back of the two adjacent transmission occasions for uplink channel transmission.
[0083] The first transmission resource corresponds to a transmission occasion in front of two adjacent transmission occasions, and the uplink channel is transmitted by using a beam facing one TRP direction for cooperative transmission. The second transmission resource corresponds to a transmission occasion in back of the two adjacent transmission occasions.
[0084] For example, the first transmission resource corresponds to an i th transmission occasion, the second transmission resource corresponds to an i+1 th transmission occasion, i is a positive integer, and the i th transmission occasion and the i+1 th transmission occasion represent two adjacent transmission occasions in sequence.
[0085] The transmission occasion includes a transmission resource in the time domain. The transmission occasion is at least one symbol in the time domain. For example, the transmission occasion in step 220 refers to an actual transmission occasion. The actual transmission occasion is an actual transmission occasion used by the terminal device when finally performing uplink channel transmission. For example, in addition to the actual transmission occasion, there is also a nominal transmission occasion. The nominal transmission occasion is a transmission occasion configured by the network device for the terminal device to perform uplink channel transmission. For example, the terminal device finally determines the actual transmission occasion for the repeated transmission of the uplink channel according to the nominal transmission occasion configured by the network device and in combination with the beam switching time required for switching the beam direction.
[0086] For example, the terminal device determines the first transmission resource and the second transmission resource based on the resource configuration of the uplink channel. The terminal determines the transmission resource in two ways, including deletion and delay. Deletion means that at least one of the first transmission resource and the second transmission resource is determined by deleting the beam switching time. Delay means that the second transmission resource is determined by delaying the beam switching time after the first transmission resource.
[0087] For example, the network device sends the resource configuration of the uplink channel to the terminal device. The terminal device receives the resource configuration sent by the network device.
[0088] For example, the repeated transmission of the uplink channel to the same data includes at least two repeated transmissions. The two adjacent repeated transmissions in step 220 refer to the two adjacent repeated transmissions that need to switch the beam direction in the at least two repeated transmissions.
[0089] For example, the terminal device needs to perform four times of repeated transmissions, the first repeated transmission is transmitted to the first TRP using the first beam direction, the second repeated transmission is transmitted to the first TRP using the first beam direction, the third repeated transmission is transmitted to the second TRP using the second beam direction, and the fourth repeated transmission is transmitted to the third TRP using the third beam direction. Then, the adjacent two repeated transmissions in step 220 can be the second repeated transmission and the third repeated transmission, or the adjacent two repeated transmissions can be the third repeated transmission and the fourth repeated transmission.
[0090] For example, there is an interval time between the first transmission occasion corresponding to the first transmission resource and the second transmission occasion corresponding to the second transmission resource, and the interval time is greater than or equal to the beam switching time for switching the beam direction.
[0091] For example, the data transmitted in the uplink channel can be uplink data or uplink signaling.
[0092] For example, the beam switching time is the time reserved for the terminal device to switch the beam direction, and the beam switching time is configured or predefined by the network device. The size of the beam switching time will be different according to different scenarios, for example, the beam switching time between beams on the same panel (antenna panel) and different panels of the terminal device can not be the same.
[0093] In step 240, the network device receives the adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0094] For example, the network device receives the adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively, through different TRPs.
[0095] In summary, the method provided in this embodiment can perform the adjacent two repeated transmissions of the uplink channel on two transmission resources with an interval of the beam switching time, use different transmission beams for the two repeated transmissions, and transmit to different TRPs of the same base station. The beam switching time is reserved for the beam switching by considering that the terminal device needs to perform the beam switching when transmitting the uplink channel to different TRPs using different beam directions, so as to facilitate the terminal device to perform the repeated transmission of the uplink channel to multiple TRPs of the same base station.
[0096] For example, the uplink channel can be a PUCCH (Physical Uplink Control Channel) or a PUSCH (Physical Uplink Shared Channel).
[0097] The multi-TRP based uplink channel enhancement scheme is mainly based on the PUCCH / PUSCH repetition transmission scheme of R16 (Release 16). First, the uplink transmission scheme of R16 is introduced, that is, PUCCH only supports repetition transmission between slots, PUSCH supports repetition transmission type A mode between slots, and repetition transmission type B mode across slots.
[0098] I. PUCCH intra-slot repetition transmission.
[0099] In R15 (Release 15) / 16, the uplink coverage problem is considered, and a mechanism of repetition transmission in multiple slots is introduced for PUCCH (corresponding to PUCCH format 1 / 3 / 4). Different PUCCH resources are transmitted in different transmission occasions of each slot according to the same transmission symbol length, as shown in Figure 3 A PUCCH repetition transmission can only use one PUCCH resource, which is configured with a beam direction spatialRelationInfo (spatial relation information) and applied to all transmission occasions. The network device configures the supported corresponding repetition transmission times for PUCCH format through RRC (Radio Resource Control) high layer signaling, and the range of the indicated repetition transmission times is defined as {1, 2, 4, 8}. Different PUCCH resources can correspond to different PUCCH formats.
[0100] II. PUSCH inter-slot repetition transmission.
[0101] The two ways of uplink PUSCH time domain repetition transmission enhancement are: the repetition type A transmission mode and the repetition type B transmission mode introduced by R16.
[0102] 1) PUSCH repetition type A transmission mode.
[0103] The slot-level Slot Aggregation (aggregation) PUSCH transmission of R16 is suitable for some cases with very low latency requirement and very high reliability requirement. A PUSCH is transmitted in K consecutive slots, that is, K transmission occasions, starting from the Sth symbol in the starting slot, each transmission occasion lasts for L symbols, and S+L is different from the slot boundary. For example, as shown in Figure 4 S is equal to 1 and L is equal to 4. The terminal device performs the first repetition transmission from the 1st symbol to the 4th symbol of the first slot, and performs the second repetition transmission from the 1st symbol to the 4th symbol of the second slot.
[0104] 2) PUSCH repeat type B transmission mode.
[0105] To reduce latency and improve reliability, Release 16 supports a PUSCH repetition scheme based on mini-slots (also known as "sub-slots"), and allows PUSCH transmission across time slots to further reduce latency. In the time domain, a PUSCH begins transmission on the S-th symbol in the initial time slot, and K nominal repetitions are sent consecutively. Each repetition occupies L symbols back-to-back, and the transmission of S+L symbols can cross time slot boundaries.
[0106] like Figure 5 As shown, when S equals 1 and L equals 4, the terminal device is configured to perform two repeated transmissions of the uplink channel. The terminal device performs the first repeated transmission in the first to fourth symbols of the first time slot, and the second repeated transmission in the fifth to eighth symbols of the first time slot.
[0107] If a transmission occurs at a time slot boundary, the transmission will be re-segmented.
[0108] like Figure 6 As shown, when S equals 1 and L equals 4, the terminal device is configured to perform four uplink channel retransmissions. The terminal device performs the first retransmission from the 1st to the 4th symbol of the first time slot, and the second retransmission from the 5th to the 8th symbol of the first time slot. Since, according to the configuration information, the four symbols of the third retransmission cross the time slot boundary, the third retransmission is split into two retransmissions: the third retransmission occurs from the 9th to the 10th symbol of the first time slot, and the fourth retransmission occurs from the 1st to the 2nd symbol of the second time slot. The fifth retransmission occurs from the 3rd to the 7th symbol of the second time slot. That is, the terminal device actually performs five retransmissions, sending the same data in each retransmission.
[0109] like Figure 7 As shown, when S equals 1 and L equals 14, the terminal device is configured to perform one uplink channel retransmission. Since a time slot is 10 symbols long, but each transmission requires 14 symbols, the 14 symbols of the first retransmission will cross the time slot boundary, splitting the first retransmission into two retransmissions. The first retransmission occurs from the 1st to the 10th symbol of the first time slot, and the second retransmission occurs from the 1st to the 4th symbol of the second time slot. That is, the terminal device actually performs two retransmissions, sending the same data in each retransmission.
[0110] For the whole transmission, time slot L*K represents the time domain resource window length of PUSCH transmission, and DL (Downlink) symbols are discarded for the transmission of PUSCH. The base station can configure SFI (Short Elementary File Identifier) semi-static flexible symbols as dynamic UL (Uplink) symbols or dynamic DL symbols, so the semi-static flexible symbols can be available symbols or unavailable symbols for PUSCH. When there are unavailable symbols, the terminal device needs to discard the unavailable symbols and then transmit on the remaining available symbols. The base station can also configure the UE (User Equipment) through signaling to use an invalid symbol pattern, that is, on the invalid symbols indicated by the signaling, the UE does not transmit uplink data.
[0111] In the standardization of R16, the main definition is the enhanced transmission scheme based on multi-point cooperative transmission adopted by downlink PDSCH, and the application of base station multi-TRP / PANEL uses the cooperation between multiple TRPs or panels to perform transmission / reception of channels from multiple beams in multiple directions, which can better overcome various shielding / blocking effects, guarantee the robustness of link connection, and be suitable for URLLC (Ultra Reliable Low Latency Communication) service to improve transmission quality and meet reliability requirements. R17 needs to continue to enhance uplink transmission using multi-TRP technology, including uplink control channel PUCCH and uplink data channel PUSCH. In the R17 multi-TRP enhancement, PUCCH / PUSCH supports cooperative sending of the same transport block (Transport Block, TB) to different TRP directions at different transmission occasions (TO, Transmission Occasion) under the above defined transmission mode, in order to further apply spatial multiplexing transmission to improve transmission reliability.
[0112] For PUCCH channel transmission, the possible scheme of R17 enhancement is:
[0113] I. PUCCH inter-slot repetition transmission.
[0114] Similar to the TDM (Time Division Multiplexing) repetition transmission mode of R15 / R16, it is realized to send in multiple time slots in multiple beam directions of multiple TRPs.
[0115] II. PUCCH intra-slot repetition transmission.
[0116] i.e. joint transmission in multiple beam directions towards multiple TRPs in one time slot.
[0117] 1) sub-slot based transmission scheme within a time slot:
[0118] i.e. repetition of PUCCH in sub-slot within a time slot. For example, as shown in FIG. 3, two times of repetition transmission of uplink channel in a time slot, using 1st beam 301 and 2nd beam 302 respectively to transmit the same data to different TRPs on two physical resource blocks in the same frequency domain within a time slot. Figure 8
[0119] 2) frequency hopping based transmission scheme within a time slot:
[0120] i.e. different beams are used to transmit on different symbol groups (or physical resource blocks) corresponding to two hops within a time slot. For example, as shown in FIG. 4, two times of repetition transmission of uplink channel in a time slot, using 1st beam 401 and 2nd beam 402 respectively to transmit the same data to different TRPs on two physical resource blocks in different frequency domain within a time slot. Figure 9
[0121] wherein the mapping relationship between the beam transmission direction of PUCCH / PUSCH transmitted by the terminal device towards different TRPs and the different transmission occasions can be considered in multiple mapping schemes, and three typical schemes are taken as examples as follows:
[0122] Scheme a: periodic mapping. Two beam directions are cyclically mapped to the configured multiple transmission occasions in turn, for example, when 4 times of repetition transmission is performed, the mapping pattern of beam direction can be #1#2#1#2, wherein #1 corresponds to the first beam direction and #2 corresponds to the second beam direction.
[0123] Scheme b: continuous mapping. Two beam directions are cyclically mapped to the configured multiple transmission occasions in succession, for example, when 4 times of repetition transmission is performed, the mapping pattern of beam direction can be #1#1#2#2; for more than 4 times of repetition transmission, the pattern is repeated, for example, for 8 times of repetition transmission, the mapping pattern of beam direction can be #1#1#2#2#1#1#2#2.
[0124] Scheme c: half mapping. Two beam directions are cyclically mapped to the configured multiple transmission occasions in succession, for example, when 8 times of repetition transmission is performed, the mapping pattern of beam direction can be #1#1#1#1#2#2#2#2.
[0125] The method for determining the first transmission resource and the second transmission resource by the terminal device in combination with the beam switching time includes two methods of deletion and delay.
[0126] The deletion can be understood as determining the two transmission resources after deleting the beam switching time from the nominal transmission occasion. The delay can be understood as obtaining the actual transmission occasion after delaying the nominal transmission occasion corresponding to the later repeated transmission by the beam switching time.

[0138] (XI) For PUSCH inter-slot repetition Type B repetition transmission, the transmission resources are determined by delaying the transmission resource corresponding to the second repetition transmission.
[0139] (XII) The transmission resources are determined by configuring the beam switching time as invalid symbols.
[0140] The above embodiments are not in any particular order.
[0141] First, for embodiments (I) to (VI), the terminal device can determine the first transmission resource and the second transmission resource by deleting.
[0142] (I) For PUCCH intra-slot repetition transmission based on sub-slots, the transmission resources are determined by deleting.
[0143] Please refer to Figure 10 , which shows a flowchart of an uplink channel transmission method provided by an embodiment of the present application. The method can be applied to Figure 1 the system architecture shown.
[0144] The method is applied to PUCCH repetition transmission based on sub-slots within a slot; the resource configuration of the uplink channel includes: two consecutive sub-slots configured for adjacent two repetition transmissions; the beam switching time is X symbols, the sub-slot includes M symbols, X and M are positive integers, and X is less than or equal to M.
[0145] The method includes the following steps.
[0146] Step 201, the terminal device determines the first transmission resource as the M symbols of the first sub-slot in the two sub-slots, and determines the second transmission resource as the last (M-X) symbols of the second sub-slot in the two sub-slots.
[0147] Taking two repetition transmissions within the same slot as an example, the terminal deletes the first X symbols from the second sub-slot corresponding to the second repetition transmission according to the beam switching time of X symbols.
[0148] For example, as shown in Figure 11 , when the size of the sub-slot is 7 symbols and the beam switching time is 1 symbol, the 7 symbols of the first sub-slot in the slot are determined as the first transmission resource 401, the first symbol is deleted in the second sub-slot in the slot as the beam switching time, and the last 6 symbols of the second sub-slot are determined as the second transmission resource 402.
[0149] In an optional implementation, the terminal device can further determine the first (M-X) symbols in the first of the two sub-slots as the first transmission resource, and determine the M symbols in the second of the two sub-slots as the second transmission resource.
[0150] At step 220, the terminal device performs adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0151] At step 240, the network device receives adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0152] To sum up, the method provided in this embodiment enables the terminal device to transmit the data of the second repeated transmission on the remaining transmission resource by deleting the beam switching time in the transmission resource corresponding to the second repeated transmission, so as to realize the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0153] (II) For the repeated transmission of PUCCH based on the frequency hopping resource in a slot, the transmission resource is determined by the way of average allocation after deleting the beam switching time from the transmission resources of twice repeated transmission.
[0154] Please refer to Figure 12 , which shows the flowchart of the uplink channel transmission method provided in an embodiment of the present application. The method can be applied in Figure 1 the system architecture shown.
[0155] The method is applied to the repeated transmission of PUCCH in a slot based on the PUCCH in the same PUCCH resource; the resource configuration of the uplink channel includes N symbols of adjacent twice repeated transmission configured for the same PUCCH resource, and the beam switching time is X symbols, X is a positive integer, N is an integer greater than 1, and X is less than or equal to N.
[0156] The method includes the following steps.
[0157] At step 202, the terminal device calculates (N-X) / 2 to obtain N1, and calculates (N-X) / 2 to obtain N2; determines the first N1 symbols in the N symbols as the first transmission resource, and determines the last N2 symbols in the N symbols as the second transmission resource.
[0158] Taking twice repeated transmission in the same slot as an example, the terminal calculates the number of symbols occupied by the two transmission resources on average after deleting X symbols from the N symbols configured for twice repeated transmission according to the beam switching time of X symbols, and determines the first transmission resource and the second transmission resource according to the number of symbols.
[0159] For example, as shown in Figure 13 When N is 14 symbols and the beam switching time is 1 symbol, (N-X) / 2 is rounded down to 6, (N-X) / 2 is rounded up to 7, the first symbol to the sixth symbol in the slot is determined as the first transmission resource 401, the seventh symbol is used as the beam switching time, and the eighth symbol to the fourteenth symbol in the slot is determined as the second transmission resource 402.
[0160] In an optional implementation, the terminal device can further calculate N1 by rounding down (N-X) / 2, calculate N2 by rounding up (N-X) / 2, determine the first N2 symbols in the N symbols as the first transmission resource, and determine the last N1 symbols in the N symbols as the second transmission resource.
[0161] For example, as shown in Figure 14 When N is 14 symbols and the beam switching time is 1 symbol, (N-X) / 2 is rounded down to 6, (N-X) / 2 is rounded up to 7, the first symbol to the seventh symbol in the slot is determined as the first transmission resource 401, the eighth symbol is used as the beam switching time, and the ninth symbol to the fourteenth symbol in the slot is determined as the second transmission resource 402.
[0162] Step 220, the terminal device performs adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0163] Step 240, the network device receives adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0164] In summary, the method provided in this embodiment achieves the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station by deleting the beam switching time from the N symbols configured for twice repeated transmission, evenly allocating the remaining symbols to the twice repeated transmission, obtaining the number of symbols occupied by the two transmission resources, and then determining the two transmission resources from the N symbols.
[0165] (Three) For the repeated transmission of PUCCH based on the frequency hopping resource in the slot, the transmission resource is determined by deleting the beam switching time from the transmission resource corresponding to the second repeated transmission.
[0166] Please refer to Figure 15 which shows a flowchart of an uplink channel transmission method provided in an embodiment of the application. The method can be applied to Figure 1 the system architecture shown in the figure.
[0167] This method is applied to repeated PUCCH transmissions within the same PUCCH resource in a time slot; the uplink channel resource configuration includes: N symbols configured for two adjacent repeated transmissions of the same PUCCH resource, with a beam switching time of X symbols, where X is a positive integer, N is an integer greater than 1, and X is less than N.
[0168] The method includes the following steps.
[0169] Step 203: The terminal device calculates N / 2 and rounds it down to get N3; calculates N / 2 and rounds it up to get N4; determines the first N3 symbols out of the N symbols as the first transmission resource; and determines the last (N4-X) symbols out of the N symbols as the second transmission resource.
[0170] Taking two repeated transmissions within the same time slot as an example, the terminal divides the N symbols configured for the two repeated transmissions equally into two repeated transmissions according to the beam switching time of X symbols, so as to obtain the number of symbols occupied by the two repeated transmissions respectively. Then, the beam switching time is removed from the number of symbols occupied by the second repeated transmission to obtain the first transmission resource and the second transmission resource.
[0171] For example, such as Figure 16 As shown, when N is 14 symbols and the beam switching time is 1 symbol, then N / 2 is rounded down to 7 and N / 2 is rounded up to 7. The first to seventh symbols in the time slot are determined as the first transmission resource 401, the eighth symbol is used as the beam switching time, and the ninth to fourteenth symbols in the time slot are determined as the second transmission resource 402.
[0172] In one alternative implementation, the terminal device may further calculate N / 2 and round down to obtain N3; calculate N / 2 and round up to obtain N4; determine the first (N3-X) symbols out of the N symbols as the first transmission resource; and determine the last N4 symbols out of the N symbols as the second transmission resource.
[0173] In one alternative implementation, the terminal device may further calculate N / 2 and round down to obtain N3; calculate N / 2 and round up to obtain N4; determine the first N4 symbols out of the N symbols as the first transmission resource; and determine the last (N3-X) symbols out of the N symbols as the second transmission resource.
[0174] In one alternative implementation, the terminal device may further calculate N / 2 and round down to obtain N3; calculate N / 2 and round up to obtain N4; determine the first (N4-X) symbols out of the N symbols as the first transmission resource; and determine the last N3 symbols out of the N symbols as the second transmission resource.
[0175] At step 220, the terminal device performs adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0176] At step 240, the network device receives adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0177] To sum up, the method provided in the embodiment determines the first transmission resource and the second transmission resource by calculating the average number of symbols occupied by each transmission according to the N symbols configured for the two repeated transmissions, and then deleting the beam switching time from the number of symbols occupied by the second repeated transmission, so as to realize the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0178] (Four) For the repeated transmission of PUCCH based on the frequency hopping resource in a time slot, the transmission resource is determined by the way of average allocation after deleting the beam switching time from the remaining available transmission resources in the time slot.
[0179] Please refer to Figure 17 , which shows the flowchart of the uplink channel transmission method provided in an embodiment of the application. The method can be applied to Figure 1 the system architecture shown.
[0180] The method is applied to the repeated transmission of PUCCH based on the same PUCCH resource in a time slot; the resource configuration of the uplink channel includes N symbols of adjacent two repeated transmissions configured for the same PUCCH resource, and there are Y symbols between the last symbol of the N symbols and the first symbol of the next time slot; the beam switching time is X symbols, and X and Y are positive integers, and N is an integer greater than 1.
[0181] The method includes the following steps.
[0182] At step 204, the terminal device calculates (Y+N-X) / 2 to obtain N5; calculates (Y+N-X) / 2 to obtain N6; determines the first N5 symbols in the (N+Y) symbols as the first transmission resource; and determines the last N6 symbols in the (N+Y) symbols as the second transmission resource.
[0183] Taking the two repeated transmissions in the same time slot as an example, the terminal calculates the average number of symbols occupied by the two transmission resources after deleting X symbols from the N symbols configured for the two repeated transmissions and the Y symbols to the end of the time slot according to the beam switching time of X symbols, and determines the first transmission resource and the second transmission resource according to the number of symbols.
[0184] For example, as shown in Figure 18As shown, when N is 14 symbols, the beam switching time is 1 symbol, and the 5th symbol to the 13th symbol in the slot are configured for the adjacent two times of repeated transmission. Then, (Y+N-X) / 2 is rounded down to 4, (Y+N-X) / 2 is rounded up to 5, the 5th symbol to the 8th symbol in the slot are determined as the first transmission resource 401, the 9th symbol is used as the beam switching time, and the 10th symbol to the 14th symbol in the slot are determined as the second transmission resource 402.
[0185] In an optional implementation, the terminal device can further calculate N5 by rounding down (Y+N-X) / 2; calculate N6 by rounding up (Y+N-X) / 2; determine the first N6 symbols in the (N+Y) symbols as the first transmission resource; and determine the last N5 symbols in the (N+Y) symbols as the second transmission resource.
[0186] In step 220, the terminal device performs the adjacent two times of repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0187] In step 240, the network device receives the adjacent two times of repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0188] In summary, the method provided in this embodiment calculates the number of symbols occupied by the two times of repeated transmission by deleting the beam switching time from the remaining available (N+Y) symbols in the slot, and then determines the first transmission resource and the second transmission resource, so as to realize the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0189] (Five) For the repeated transmission of PUCCH based on the frequency hopping resource in the slot, the transmission resource is determined by deleting the beam switching time from the transmission resource corresponding to the second time of repeated transmission in the remaining available transmission resource in the slot.
[0190] Please refer to Figure 19 which shows a flowchart of an uplink channel transmission method provided in an embodiment of the present application. The method can be applied to Figure 1 the system architecture shown.
[0191] The method is applied to the repeated transmission of PUCCH based on the same PUCCH resource in the slot; the resource configuration of the uplink channel includes: N symbols of the adjacent two times of repeated transmission configured for the same PUCCH resource, and there are Y symbols between the last symbol of the N symbols and the first symbol of the next slot; the beam switching time is X symbols, and X and Y are positive integers, and N is an integer greater than 1.
[0192] The method includes the following steps.
[0193] In step 205, the terminal device calculates (Y+N) / 2 down to N7; calculates (Y+N) / 2 up to N8; determines the first N7 symbols in the (N+Y) symbols as the first transmission resource; and determines the last (N8-X) symbols in the (N+Y) symbols as the second transmission resource.
[0194] For example, taking the case of twice repeated transmission in the same time slot, the terminal calculates the average number of symbols of N symbols and Y symbols at the end of the time slot according to the beam switching time X symbols, deletes the beam switching time from the number of symbols corresponding to the second repeated transmission, and further determines the first transmission resource and the second transmission resource.
[0195] For example, as shown in FIG. 4, when N is 14 symbols and the beam switching time is 1 symbol, 9 symbols from the 5th symbol to the 13th symbol in the time slot are configured for adjacent twice repeated transmission. Then (Y+N) / 2 down to 5 and (Y+N) / 2 up to 5, the first transmission resource 401 is determined as the 5th symbol to the 9th symbol in the time slot, the 10th symbol is used as the beam switching time, and the second transmission resource 402 is determined as the 11th symbol to the 14th symbol in the time slot. Figure 20 In an alternative implementation, the terminal device can further calculate (Y+N) / 2 down to N7; calculate (Y+N) / 2 up to N8; determine the first N8 symbols in the (N+Y) symbols as the first transmission resource; and determine the last (N7-X) symbols in the (N+Y) symbols as the second transmission resource.
[0196] In an alternative implementation, the terminal device can further calculate (Y+N) / 2 down to N7; calculate (Y+N) / 2 up to N8; determine the first (N8-X) symbols in the (N+Y) symbols as the first transmission resource; and determine the last N7 symbols in the (N+Y) symbols as the second transmission resource.
[0197] In an alternative implementation, the terminal device can further calculate (Y+N) / 2 down to N7; calculate (Y+N) / 2 up to N8; determine the first (N7-X) symbols in the (N+Y) symbols as the first transmission resource; and determine the last N8 symbols in the (N+Y) symbols as the second transmission resource.
[0198] In step 220, the terminal device performs adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0199]
[0200] At step 240, the network device receives the adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0201] To sum up, the method provided in the embodiment determines the first transmission resource and the second transmission resource by calculating the number of symbols occupied by the two repeated transmissions respectively in the N+Y symbols available in the time slot, and then deleting the beam switching time from the number of symbols occupied by the second repeated transmission, so as to realize the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0202] (VI) For the repeated transmission of PUSCH inter-slot repetition type B, the transmission resource is determined by the way of average allocation after deleting the beam switching time from the transmission resources of the two repeated transmissions.
[0203] Please refer to Figure 21 which shows the flowchart of the uplink channel transmission method provided in an embodiment of the application. The method can be applied to Figure 1 the system architecture shown.
[0204] The method is applied to the PUSCH repeated transmission of the cross-slot transmission (or cross-slot transmission) based on the nominal transmission occasion (nominal Transmission Occasion) configuration; the resource configuration of the uplink channel includes: two continuous nominal transmission occasions configured for the adjacent two repeated transmissions, each nominal transmission occasion occupies A symbol time domain resources, the beam switching time is X symbols, and X and A are positive integers.
[0205] The method includes the following steps.
[0206] At step 206, the terminal device determines the A symbols of the earlier nominal transmission occasion in the two nominal transmission occasions as the first transmission resource, and determines the last (A-X) symbols of the later nominal transmission occasion in the two nominal transmission occasions as the second transmission resource.
[0207] For example, the terminal device is configured with two nominal transmission occasions for the two repeated transmissions according to the beam switching time of X symbols, and the terminal device deletes the beam switching time from the nominal transmission occasion corresponding to the second repeated transmission, and then determines the first transmission resource and the second transmission resource.
[0208] For example, as shown in Figure 22As shown, when each nominal transmission occasion occupies 4 symbols, the beam switching time is 1 symbol, and the first nominal transmission occasion and the second nominal transmission occasion are configured for two adjacent repeated transmissions. Then the first nominal transmission occasion is determined as the first transmission resource 401, the 1st symbol of the second nominal transmission occasion is taken as the beam switching time, and the last three symbols of the second nominal transmission occasion are determined as the second transmission resource 402.
[0209] In an optional implementation, the terminal device can also determine the first (A-X) symbols of the first nominal transmission occasion of the two nominal transmission occasions as the first transmission resource, and determine the A symbols of the second nominal transmission occasion of the two nominal transmission occasions as the second transmission resource.
[0210] Optionally, when the number of repetitions of the PUSCH is multiple, in every two adjacent repeated transmissions that need to switch the beam direction, the beam switching time is deleted in front of the nominal transmission occasion corresponding to the latter repeated transmission.
[0211] For example, as shown in FIG. 4, when the number of repetitions of the PUSCH is 2, the beam switching time is 1 symbol, and the first nominal transmission occasion and the second nominal transmission occasion are configured for two adjacent repeated transmissions. Figure 23As shown, the terminal device is configured to need to perform four PUSCH repeated transmissions, the first nominal repeated transmission and the third nominal repeated transmission are transmitted to the first TRP in the first beam direction, and the second nominal repeated transmission and the fourth nominal repeated transmission are transmitted to the second TRP in the second beam direction. Since each transmission occupies a nominal transmission occasion of 4 symbols, and each time slot is 10 symbols, at the third nominal repeated transmission, the terminal device will cross the time slot boundary, and the terminal device splits the third nominal repeated transmission into two actual repeated transmissions, so that the terminal device actually needs to perform five actual repeated transmissions, that is, the first nominal repeated transmission is the first actual repeated transmission, the second nominal repeated transmission is the second actual repeated transmission, the third nominal repeated transmission includes the third actual repeated transmission and the fourth actual repeated transmission, and the fourth nominal repeated transmission is the fifth actual repeated transmission. Thus, the actual repeated transmissions that need to perform beam direction switching are: the first actual repeated transmission and the second actual repeated transmission, the second actual repeated transmission and the third actual repeated transmission, and the fourth actual repeated transmission and the fifth actual repeated transmission. The terminal device deletes the first X symbols in the nominal transmission occasion corresponding to the latter actual repeated transmission from the above-mentioned adjacent two repeated transmissions (actual repeated transmissions) that need to perform beam switching as a beam switching time. When X is 1, the first transmission resource used by the first actual repeated transmission is the first symbol to the fourth symbol of the first time slot; the fifth symbol of the first time slot is the beam switching time, the second transmission resource used by the second actual repeated transmission is the sixth symbol to the eighth symbol of the first time slot; the ninth symbol of the first time slot is the beam switching time, the third transmission resource used by the third actual repeated transmission is the tenth symbol of the first time slot; the fourth transmission resource used by the fourth actual repeated transmission is the first symbol to the second symbol of the second time slot; the third symbol of the second time slot is the beam switching time, and the fifth transmission resource used by the fifth actual repeated transmission is the fourth symbol to the sixth symbol of the second time slot.
[0212] In step 220, the terminal device performs adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0213] In step 240, the network device receives adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0214] In summary, the method provided in the embodiment realizes the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station by deleting the beam switching time in the nominal transmission occasion corresponding to the subsequent repeated transmission of the PUSCH.
[0215] Then, for embodiments (vii) to (xii), the terminal device may determine the first transmission resource and the second transmission resource in a delayed manner.
[0216] (vii) For the repeated transmission of PUCCH based on sub-time slots within a time slot, the transmission resources are determined by delaying by one sub-time slot.
[0217] Please refer to Figure 24 It illustrates a flowchart of an uplink channel transmission method provided in one embodiment of this application, which can be applied to... Figure 1 In the system architecture shown.
[0218] This method is applied to PUCCH repetition transmission based on sub-time slots within a time slot; the resource configuration of the uplink channel includes: two consecutive sub-time slots are configured for two adjacent repetition transmissions; the beam switching time is X symbols, and the sub-time slot includes M symbols, where X and M are positive integers, and X is less than or equal to M; the starting symbol configured for two adjacent repetition transmissions is the S-th symbol within the time slot, where S is a positive integer.
[0219] The method includes the following steps.
[0220] Step 207: The terminal device determines the first sub-time slot starting from the Sth symbol as the first transmission resource; and determines the second sub-time slot starting from the (S+2M)th symbol as the second transmission resource. The (S+2M)th symbol is obtained by delaying the first transmission resource by one sub-time slot.
[0221] Taking two repeated transmissions within the same time slot as an example, the terminal device sets the beam switching time to X symbols. The terminal device delays the sub-time slot corresponding to the second repeated transmission by one sub-time slot, and the delayed sub-time slot is used as the beam switching time.
[0222] For example, such as Figure 25 As shown, when each sub-time slot contains 2 symbols, the beam switching time is 1 symbol, and S is 1, then the first sub-time slot within the time slot is determined as the first transmission resource 401, the second sub-time slot is used as the beam switching time, and the third sub-time slot is determined as the second transmission resource 402.
[0223] For example, after a delay of one sub-slot, the second sub-slot of the second repeated transmission may exceed the slot boundary. In this case, the symbols exceeding the slot boundary in the second sub-slot need to be deleted, and the deleted second sub-slot is used as the second transmission resource. That is, in response to the last Z symbols of the second sub-slot starting from the (S+2M)th symbol exceeding the slot boundary, the terminal device determines the first (MZ) symbols of the second sub-slot as the second transmission opportunity, where Z is a positive integer less than M.
[0224] For example, such as Figure 26As shown, the time slot is five symbols, each sub-slot contains 2 symbols, the beam switching time is 1 symbol, S is 1, the first sub-slot in the time slot is determined as the first transmission resource 401, the second sub-slot is used as the beam switching time, and the first symbol in the third sub-slot is determined as the second transmission resource 402.
[0225] In step 220, the terminal device performs adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0226] In step 240, the network device receives adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0227] In summary, the method provided in the embodiment delays a sub-slot for beam switching after the first sub-slot of the first repeated transmission, uses the third sub-slot as the second transmission resource of the second repeated transmission, and realizes repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0228] (Eight) For PUCCH repeated transmission based on sub-slots in a time slot, the transmission resource is determined in a manner of delaying the beam switching time.
[0229] Please refer to Figure 27 which shows a flowchart of an uplink channel transmission method provided in an embodiment of the application. The method can be applied to Figure 1 the system architecture shown.
[0230] The method is applied to PUCCH repeated transmission based on sub-slots in a time slot; the resource configuration of the uplink channel includes that adjacent twice repeated transmission is configured with two continuous sub-slots; the beam switching time is X symbols, a sub-slot includes M symbols, X and M are positive integers, and X is less than or equal to M; the starting symbol configured for adjacent twice repeated transmission is the Sth symbol in the time slot, and S is a positive integer.
[0231] The method includes the following steps.
[0232] In step 208, the terminal device determines the first sub-slot starting from the Sth symbol as the first transmission resource, and determines the second sub-slot starting from the (S+M+X)th symbol as the second transmission resource, the (S+M+X)th symbol being obtained by delaying the first transmission resource by X symbols.
[0233] Taking twice repeated transmission in the same time slot as an example, the terminal device delays the sub-slot corresponding to the second repeated transmission by the beam switching time of X symbols, and then determines the second transmission resource of the second repeated transmission.
[0234] For example, such as Figure 28 As shown, when each sub-time slot contains 2 symbols, the beam switching time is 1 symbol, and S is 1, then the first sub-time slot within the time slot is determined as the first transmission resource 401, the first symbol of the second sub-time slot is taken as the beam switching time, and the second sub-time slot composed of the second symbol of the second sub-time slot and the first symbol of the third sub-time slot is determined as the second transmission resource 402.
[0235] For example, after a delay of one sub-slot, the second sub-slot of the second repeated transmission may exceed the slot boundary. In this case, the symbols exceeding the slot boundary in the second sub-slot need to be deleted, and the deleted second sub-slot is used as the second transmission resource. That is, in response to the last Z symbols of the second sub-slot starting from the (S+M+X)th symbol exceeding the slot boundary, the terminal device determines the first (MZ) symbols of the second sub-slot as the second transmission opportunity, where Z is a positive integer less than M.
[0236] For example, such as Figure 29 As shown, the time slot has 4 symbols, each sub-time slot contains 2 symbols, the beam switching time is 1 symbol, and S is 1. Then, the first sub-time slot in the time slot is determined as the first transmission resource 401, the first symbol of the second sub-time slot is used as the beam switching time, and the first symbol in the second sub-time slot is determined as the second transmission resource 402.
[0237] Step 220: The terminal device performs two consecutive retransmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0238] Step 240: The network device receives two consecutive repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0239] In summary, the method provided in this embodiment achieves repeated transmission of uplink channels of multiple TRPs of the same base station by delaying the beam switching time after the first sub-time slot of the first repeated transmission and using the sub-time slot after the delayed beam switching time as the second transmission resource for the second repeated transmission.
[0240] (ix) For repeated transmission of PUCCH based on frequency hopping resources within a time slot, the transmission resources are determined by delaying the transmission resources corresponding to the second repeated transmission.
[0241] Please refer to Figure 30 It illustrates a flowchart of an uplink channel transmission method provided in one embodiment of this application, which can be applied to... Figure 1 In the system architecture shown.
[0242] This method is applied to repeated PUCCH transmissions within the same PUCCH resource in a time slot; the uplink channel resource configuration includes: N symbols configured for two adjacent repeated transmissions for the same PUCCH resource, and there are Y symbols between the last symbol of the N symbols and the first symbol of the next time slot; the beam switching time is X symbols, where X, Y, and N are positive integers, and X is less than or equal to Y; the starting symbol configured for two adjacent repeated transmissions is the Sth symbol in the time slot, where S is a positive integer.
[0243] The method includes the following steps.
[0244] Step 209: The terminal device calculates N / 2 and rounds it down to get N3; calculates N / 2 and rounds it up to get N4; determines the N3 symbols starting from the S-th symbol as the first transmission resource; determines the N4 symbols starting from the (S+N3+X)-th symbol as the second transmission resource, where the (S+N3+X)-th symbol is obtained by delaying the first transmission resource by X symbols.
[0245] Taking two repeated transmissions within the same time slot as an example, the terminal device calculates the number of symbols occupied by the two repeated transmissions in N symbols, with the beam switching time being X symbols. The number of symbols corresponding to the first repeated transmission is taken as the first transmission resource, the X symbols after the first transmission resource are taken as the beam switching time, and the number of symbols corresponding to the second repeated transmission after the beam switching time are taken as the second transmission resource.
[0246] For example, such as Figure 31 As shown, the beam switching time is 1 symbol, S is 5, N is 9, and Y is 1. Then, N / 2 is rounded down to 4 and N / 2 is rounded up to 5. The 5th to 8th symbols in the time slot are determined as the first transmission resource 401, the 9th symbol in the time slot is used as the beam switching time, and the 10th to 14th symbols in the time slot are determined as the second transmission resource 402.
[0247] Step 220: The terminal device performs two consecutive retransmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0248] Step 240: The network device receives two consecutive repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0249] To sum up, the method provided in the embodiment realizes the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0250] (X) For the repeated transmission of PUCCH based on the frequency hopping resource in a time slot, the transmission resource is determined by deleting the transmission resource exceeding the time slot boundary after delaying the transmission resource corresponding to the second repeated transmission.
[0251] Please refer to Figure 32 , which shows the flowchart of the uplink channel transmission method provided in an embodiment of the application. The method can be applied in Figure 1 the system architecture shown.
[0252] The method is applied to the repeated transmission of PUCCH based on the same PUCCH resource in a time slot; the resource configuration of the uplink channel includes N symbols of adjacent two repeated transmissions configured for the same PUCCH resource, and there are Y symbols between the last symbol of the N symbols and the first symbol of the next time slot; the beam switching time is X symbols, X, Y, and N are positive integers, and X is greater than or equal to Y; the starting symbol configured for the adjacent two repeated transmissions is the Sth symbol in the time slot, and S is a positive integer.
[0253] The method includes the following steps.
[0254] In step 210, the terminal device calculates N / 2 to obtain N3; calculates N / 2 to obtain N4; determines N3 symbols starting from the Sth symbol as the first transmission resource; and determines (N4-(X-Y)) symbols starting from the (S+N3+X)th symbol as the second transmission resource, the (S+N3+X)th symbol being obtained by delaying the first transmission resource by X symbols.
[0255] Taking the two repeated transmissions in the same time slot as an example, the terminal device calculates the number of symbols occupied by the two repeated transmissions in N symbols according to the beam switching time X, takes the number of symbols corresponding to the first repeated transmission as the first transmission resource, takes the X symbols after the first transmission resource as the beam switching time, and since X is greater than or equal to Y, the number of symbols corresponding to the second repeated transmission after the beam switching time is reduced by (X-Y) to obtain the second transmission resource.
[0256] For example, as shown in Figure 33As shown, the beam switching time is 1 symbol, S is 6, N is 9, and Y is 0, so N / 2 is rounded down to 4, N / 2 is rounded up to 5, the 6th symbol to the 9th symbol in the time slot is determined as the first transmission resource 401, the 10th symbol in the time slot is determined as the beam switching time, and the 11th symbol to the 14th symbol in the time slot are determined as the second transmission resource 402.
[0257] In step 220, the terminal device performs adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0258] In step 240, the network device receives adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource respectively.
[0259] In summary, the method provided in the embodiment, by evenly allocating the N symbols corresponding to the twice repeated transmission to obtain the number of symbols corresponding to each repeated transmission, starting from the starting symbol of the adjacent twice repeated transmission, the number of symbols corresponding to the first repeated transmission is determined as the first transmission resource, the second repeated transmission corresponding to the transmission resource is delayed by the beam switching time, and the number of symbols obtained by subtracting (X-Y) from the number of symbols corresponding to the second repeated transmission after the delay beam switching time is determined as the second transmission resource, realizing the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
[0260] (Eleven) For the repeated transmission of PUSCH in the slot type B repetition, the transmission resource is determined in the manner of delaying the transmission resource corresponding to the second repeated transmission.
[0261] Please refer to Figure 34 , which shows the flowchart of the uplink channel transmission method provided in an embodiment of the application. The method can be applied to Figure 1 the system architecture shown.
[0262] The method applies the PUSCH repeated transmission of the cross-slot transmission based on the nominal transmission occasion configuration; the resource configuration of the uplink channel includes: two continuous nominal transmission occasions configured for adjacent twice repeated transmission, each nominal transmission occasion occupies A symbol time domain resources, the beam switching time is X symbols, and X and A are positive integers; the starting symbol of the adjacent twice repeated transmission is the Sth symbol in the time slot, and S is a positive integer.
[0263] The method includes the following steps.
[0264] In step 211, the terminal device determines A symbols starting from the Sth symbol as the first transmission resource, and determines A symbols starting from the (S+A+X)th symbol as the second transmission resource, the (S+A+X)th symbol being obtained by delaying the first transmission resource by X symbols.
[0265] For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource.
[0266] For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource. Figure 35 For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource.
[0267] For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource.
[0268] For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource. Figure 36 For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource.
[0269] For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource.
[0270] For example, as shown in FIG. 4, when the terminal is configured with two nominal transmission occasions for two repeated transmissions according to a beam switching time of X symbols, after the terminal device determines the first nominal transmission occasion as the first transmission resource for the first repeated transmission, the terminal device delays the beam switching time and determines the second nominal transmission occasion after the delay of the beam switching time as the second transmission resource.
[0271] The resource configuration of the uplink channel further includes K nominal transmission occasions configured for K times of repeated transmission based on PUSCH resources, the K nominal transmission occasions occupy K*A time domain resources, and the K times of repeated transmission include adjacent two times of repeated transmission in which B groups of different TRPs facing the same base station use different transmission beams to transmit.
[0272] The terminal device performs the ith time of repeated transmission of the uplink channel on the first (A-W) symbols of the transmission resource corresponding to the delayed ith time of repeated transmission, in response to the fact that W symbols in the transmission resource corresponding to the delayed ith time of repeated transmission are located after the K*A symbols, W is a positive integer less than A, and i is a positive integer less than or equal to K; in response to i not being equal to K, the terminal device cancels the repeated transmission after the ith time of repeated transmission.
[0273] That is, the terminal device still performs repeated transmission of PUSCH within the time domain resource window of K*A symbols.
[0274] For example, as shown in (1) of Figure 37 , the terminal device is configured to perform four times of repeated transmission of PUSCH, the first time of repeated transmission and the third time of repeated transmission are transmitted to the first TRP in the first beam direction, and the second time of repeated transmission and the fourth time of repeated transmission are transmitted to the second TRP in the second beam direction. Each time of repeated transmission occupies one nominal transmission occasion, and each nominal transmission occasion is 4 symbols, so the time domain resource window length of the repeated transmission of PUSCH is 4*4=16 symbols. The actual repeated transmissions that need to perform beam direction switching are: the first time of repeated transmission and the second time of repeated transmission, the second time of repeated transmission and the third time of repeated transmission, and the third time of repeated transmission and the fourth time of repeated transmission. Then the terminal device determines the transmission resource of the next transmission after delaying the beam switching time between the adjacent two times of repeated transmission. As shown in (2) of Figure 37 , when X is 1, the first transmission resource used by the first time of repeated transmission is the first symbol to the fourth symbol of the first slot; the fifth symbol of the first slot is the beam switching time, the second transmission resource used by the second time of repeated transmission is the sixth symbol to the ninth symbol of the first slot; the tenth symbol of the first slot is the beam switching time, the third transmission resource used by the third time of repeated transmission is the first symbol to the fourth symbol of the second slot; the fifth symbol of the second slot is the beam switching time, and the fourth transmission resource used by the fourth time of repeated transmission is the sixth symbol of the second slot, that is, the transmission occasion of the fourth time of repeated transmission after the delay will exceed the time domain resource window by three symbols, and the four symbols will be deleted, and the fourth time of repeated transmission actually only uses one symbol.
[0275] For another example, as shown in (1) of Figure 38As shown in (1) of FIG. 1, the terminal device is configured to perform three times of PUSCH repetition transmission, the first nominal repetition transmission and the third nominal repetition transmission are transmitted to the first TRP in the first beam direction, and the second nominal repetition transmission is transmitted to the second TRP in the second beam direction. Each nominal repetition transmission occupies one nominal transmission occasion, and each nominal transmission occasion is 5 symbols, so the time domain resource window length of the PUSCH repetition transmission is 3*5=15 symbols. The actual repetition transmissions that need to perform beam direction switching are: the first nominal repetition transmission and the second nominal repetition transmission, and the second nominal repetition transmission and the third nominal repetition transmission. Then the terminal device determines the transmission resource of the next transmission after delaying the beam switching time between the adjacent two repetition transmissions. As shown in (1) of FIG. 1, the terminal device determines the transmission resource of the next transmission after delaying the beam switching time between the adjacent two repetition transmissions. Figure 38 As shown in (2) of FIG. 1, when X is 1, the first transmission resource used by the first actual repetition transmission is the first symbol to the fifth symbol of the first slot; the sixth symbol of the first slot is the beam switching time, and since the transmission occasion of the second nominal repetition transmission after the delay crosses the slot boundary of the slot, the second nominal repetition transmission is split into the second actual repetition transmission and the third actual repetition transmission, the second transmission resource used by the second actual repetition transmission is the seventh symbol to the tenth symbol of the first slot, the third transmission resource used by the third actual repetition transmission is the first symbol of the second slot; the second symbol of the second slot is the beam switching time, the third nominal repetition transmission is the fourth actual repetition transmission, and the fourth transmission resource used by the fourth actual repetition transmission is the third symbol to the fifth symbol of the second slot, that is, the transmission occasion of the fourth actual repetition transmission after the delay will exceed the time domain resource window by 2 symbols, and the 2 symbols exceeding the time domain resource window are deleted, and the fourth actual repetition transmission actually only uses 3 symbols.
[0276] Or, the terminal device continues to perform the i-th repetition transmission on the transmission resource corresponding to the i-th repetition transmission after the delay in response to the fact that at least one symbol in the transmission resource corresponding to the i-th repetition transmission after the delay is located after K*A symbols, i is a positive integer less than or equal to K.
[0277] That is, the terminal device performs K times of PUSCH transmission within a time domain resource window of K*A symbols plus B*X symbols.
[0278] For example, the terminal device is configured to need to perform four PUSCH repeated transmissions, the first repeated transmission and the third repeated transmission are transmitted to the first TRP in the first beam direction, and the second repeated transmission and the fourth repeated transmission are transmitted to the second TRP in the second beam direction. Each repeated transmission occupies one nominal transmission occasion, and each nominal transmission occasion is 4 symbols, so the time domain resource window length of the PUSCH repeated transmission is 4*4=16 symbols. The actual repeated transmissions that need to perform beam direction switching are: the first repeated transmission and the second repeated transmission, the second repeated transmission and the third repeated transmission, and the third repeated transmission and the fourth repeated transmission. The terminal device determines the transmission resource of the next transmission after delaying the beam switching time between the adjacent two repeated transmissions. When the beam switching time is 1 symbol, the first transmission resource used by the first repeated transmission is the first symbol to the fourth symbol of the time domain resource window of the first time slot; the fifth symbol of the time domain resource window is the beam switching time, the second transmission resource used by the second repeated transmission is the sixth symbol to the ninth symbol of the time domain resource window; the tenth symbol of the time domain resource window is the beam switching time, the third transmission resource used by the third repeated transmission is the eleventh symbol to the fourteenth symbol of the time domain resource window; the fifteenth symbol of the time domain resource window is the beam switching time, and the fourth transmission resource used by the fourth repeated transmission is the sixteenth symbol of the time domain resource window and the first symbol to the third symbol after the time domain resource window, that is, the transmission occasion of the fourth repeated transmission is delayed, and will exceed the time domain resource window by three symbols, and the four repeated transmissions actually use 19 symbols.
[0279] In step 220, the terminal device performs adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0280] In step 240, the network device receives adjacent two repeated transmissions of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0281] In summary, the method provided in the embodiment realizes the repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station, by delaying a beam switching time whenever the beam direction needs to be switched when performing multiple repeated transmissions of the PUSCH, and then determining the transmission resource of the next repeated transmission according to the length of the nominal transmission occasion.
[0282] (12) The transmission resource is determined by configuring the beam switching time as an invalid symbol.
[0283] Please refer to Figure 39 which shows a flowchart of an uplink channel transmission method provided in an embodiment of the application. The method can be applied to Figure 1The system architecture shown in the method comprises the following steps.
[0284] In step 212, the network device sends the resource configuration of the uplink channel to the terminal device, the first transmission resource and the second transmission resource are determined based on the resource configuration, and the resource configuration comprises configuring the beam switching time as invalid symbols, and the first transmission resource and the second transmission resource are determined from the valid symbols indicated by the resource configuration.
[0285] In step 213, the terminal device determines the first transmission resource and the second transmission resource based on the resource configuration of the uplink channel, the resource configuration comprises configuring the beam switching time as invalid symbols, and the first transmission resource and the second transmission resource are determined from the valid symbols indicated by the resource configuration.
[0286] For example, the network device can directly configure the beam switching time as invalid symbols, and the terminal device will not perform repeated transmission of the uplink channel on the invalid symbols, so that the terminal device can be reserved for beam switching.
[0287] For example, the beam switching time can be predefined or configured as invalid symbols by RRC, and the terminal device deletes the invalid symbols.
[0288] In step 220, the terminal device performs adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0289] In step 240, the network device receives adjacent twice repeated transmission of the same data in the uplink channel on the first transmission resource and the second transmission resource, respectively.
[0290] In summary, the method provided by the embodiment sets the beam switching time as invalid symbols, and realizes repeated transmission of the uplink channel of the terminal device facing multiple TRPs of the same base station.
