[0002] The new radio (NR) R16 introduces a new type of PUSCH repetition scheme, namely PUSCH repetition type B transmission, in which multiple actual repetitions can occur in a single time slot.

[0003] In NR R17, the use of multiple Transmitter Receiver Points (TRPs) and / or multiple panels with Version 16 reliability features is proposed to identify and specify features for improving the reliability and robustness of channels other than the Physical Downlink Shared Channel (PDSCH), namely: Physical Downlink Control Channel (PDCCH), PUSCH, and Physical Uplink Control Channel (PUCCH). Specifically, regarding PUSCH, PUSCH repetition with multiple beams or multiple TRPs can utilize the spatial diversity of multiple beams or TRPs transmitted by the PUSCH to increase reliability and robustness. However, how to map the repetition of PUSCH repetition type B transmissions has not yet been determined.

[0017] Figure 1 A schematic diagram illustrating a wireless communication system 100 according to some embodiments of this application.

[0018] like Figure 1 As shown, the wireless communication system 100 includes UE 102 and BS 101. Although for simplicity... Figure 1 The description specifies only one BS, but in consideration of some other embodiments of this application, the wireless communication system 100 may include more BSs. Similarly, although for simplicity... Figure 1 The description indicates only one UE, but upon consideration, in some other embodiments of this application, the wireless communication system 100 may include more UEs.

[0019] BS 101 may also be referred to as an access point, access terminal, base station, macro cell, node-B, enhanced node-B (eNB), gNB, home node-B, relay node, or device, or described using other terms used in the field. BS 101 is typically part of a radio access network that may include a controller communicatively coupled to BS 101.

[0020] UE 102 may include computing devices such as desktop computers, laptop computers, personal digital assistants (PDAs), tablet computers, smart TVs (e.g., TVs connected to the Internet), set-top boxes, game consoles, security systems (including surveillance cameras), in-vehicle computers, network devices (e.g., routers, switches, and modems), etc. According to embodiments of this application, UE 102 may include portable wireless communication devices, smartphones, cellular phones, flip phones, devices with subscriber identity modules, personal computers, selective call receivers, or any other devices capable of transmitting and receiving communication signals on a wireless network. In some embodiments, UE 102 may include wearable devices such as smartwatches, fitness trackers, optical head-mounted displays, etc. Furthermore, UE 102 may be referred to as a subscriber unit, mobile device, mobile station, user, terminal, mobile terminal, wireless terminal, fixed terminal, subscriber station, user terminal, or device, or described using other terms used in the art.

[0021] The wireless communication system 100 is compatible with any type of network capable of transmitting and receiving wireless communication signals. For example, the wireless communication system 100 is compatible with wireless communication networks, cellular telephone networks, time division multiple access (TDMA) based networks, code division multiple access (CDMA) based networks, orthogonal frequency division multiple access (OFDMA) based networks, LTE networks, 3GPP based networks, 3GPP 5G networks, satellite communication networks, high-altitude platform networks, and / or other communication networks.

[0022] For PUSCH, PUSCH repetition with multiple beams or TRPs can utilize the spatial diversity of multiple beams or TRPs in PUSCH transmission, thus greatly increasing the reliability and robustness of uplink data transmission. Unlike PUSCH repetition type A (where PUSCH transmission in the time slot of multi-slot PUSCH transmission is omitted according to the conditions in clause 11.1 of [6, TS38.213]), a new type of PUSCH repetition scheme, namely PUSCH repetition type B transmission, is specified in NR R16.

[0023] Specifically, in PUSCH repetition type B, the concepts of "nominal repetition" and "actual repetition" are introduced to identify multiple repetitions within a single time slot. According to TS 38.214, for PUSCH repetition type B, the number of nominal repetitions is given by the parameter `numberofrepetitions`. For the nth nominal repetition (where the value of n ranges from 0 to `numberofrepetitions-1`), the start time slot, start symbol, end time slot, and end symbol of the nth nominal repetition are calculated as follows:

[0024] i. The time slot with the nominal repetition start:

[0025]

[0026] ii. Start symbol relative to the start of the time slot:

[0027]

[0028] iii. The time slot where the nominal repetition ends:

[0029]

[0030] iv. End symbol relative to the start of the time slot:

[0031]

[0032] Where K s It is the time slot in which the PUSCH transmission begins, and S is the number of symbols per time slot, S is the starting symbol S relative to the start of the time slot, and L is the number of consecutive symbols L counted from the symbol S allocated for each nominal repetition transmitted for PUSCH repetition type B. S and L are provided by the following parameters: the startSymbol parameter and length parameter of the index row of the resource allocation table, respectively.

[0033] Meanwhile, for PUSCH repetition type B, there may be one or more invalid symbols between the start and end symbols. The UE determines these invalid symbols transmitted in PUSCH repetition type B based on the following rules:

[0034] i. Symbols indicated as downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. Since these symbols are indicated for downlink transmission, the UE considers them unusable for uplink transmission. Therefore, these symbols are invalid symbols for PUSCH repetition type B transmissions.

[0035] ii. The UE may be configured with a higher-level parameter, InvalidSymbolPattern, which provides a symbol-level bitmap spanning one or two time slots, such as the higher-level parameter symbols given by InvalidSymbolPattern. Bit values ​​equal to 1 in the symbol-level bitmap symbols indicate that the corresponding symbol is an invalid symbol transmitted as a PUSCH repetition type B. The UE may also be configured with a time-domain mode, such as the higher-level parameter periodicityAndPattern given by InvalidSymbolPattern, where each bit of periodicityAndPattern corresponds to a unit equal to the duration of the symbol-level bitmap symbols, and a bit value equal to 1 indicates that the symbol-level bitmap symbols exist within that unit. The length of periodicityAndPattern may be {1, 2, 4, 5, 8, 10, 20, or 40}.

[0036] The number of units is 1, but the maximum value is 40ms. The first symbol of the periodicityAndPattern every 40ms / P periods is the first symbol in the frame nf mod 4 = 0, where P is the duration of the periodicityAndPattern in milliseconds. When the periodicityAndPattern parameter is not configured, for a symbol-level bitmap spanning two slots, the bits of the first and second slots correspond to the even and odd slots of the radio frame, respectively, and for a symbol-level bitmap spanning one slot, the bits of that slot correspond to each slot of the radio frame. If the InvalidSymbolPattern parameter is configured, then the following determines when the UE applies the invalid symbol mode:

[0037] a) If the PUSCH is scheduled by downlink control information (DCI) format 0_1, or corresponds to a type 2 authorization configured by DCI format 0_1, and if InvalidSymbolPatternIndicator-ForDCIFormat0_1 is configured, then the UE applies the invalid symbol mode if the invalid symbol mode indicator field is set to 1; otherwise, the UE does not apply the invalid symbol mode.

[0038] b) If the PUSCH is scheduled by DCI format 0_2, or corresponds to an authorization configured by type 2 activated by DCI format 0_2, and if InvalidSymbolPatternIndicator-ForDCIFormat0_2 is configured, then the UE applies the invalid symbol mode if the invalid symbol mode indicator field is set to 1; otherwise, the UE does not apply the invalid symbol mode.

[0039] c) Otherwise, the UE applies the invalid symbol mode.

[0040] After determining (a number of) invalid symbols for each nominal repetition of PUSCH repetition type B transmission, the remaining symbols are considered as potentially valid symbols for PUSCH repetition type B transmission. If the number of potentially valid symbols for PUSCH repetition type B transmission is greater than zero for a nominal repetition, then the nominal repetition consists of one or more actual repetitions, where each actual repetition consists of a set of consecutive potentially valid symbols available for PUSCH repetition type B transmission within the time slot. Actual repetitions of individual symbols are omitted except where the number L of consecutive symbols is 1, for example, L = 1. Actual repetitions are omitted according to the conditions in Clause 11.1 of [6, TS38.213]. The redundant version to be applied on the nth actual repetition is determined according to Table 6.1.2.1-2 (where the count includes omitted actual repetitions).

[0041] The above description of nominal and actual duplication is provided in accordance with TS 38.214. The description may change or be updated as 3GPP specifications or other relevant specifications / protocols evolve, and therefore should not be limited to the above.

[0042] However, since multiple time slots can be used to transmit PUSCH repetition type B transmissions, and multiple actual PUSCH repetitions can occur within a single time slot, the mapping repetition of PUSCH repetition type B cannot be performed in a manner similar to the time-division multiplexing (TDM) scheme at the time slot level, i.e., the ultra-reliable low-latency communication (URLLC) scheme 4 at PDSCH. Therefore, embodiments of this application propose at least one technical solution for mapping PUSCH repetitions when multiple spatial relationship information representing beams in embodiments of this application are configured to utilize spatial diversity to increase robustness and reliability.

[0043] Figure 2 A flowchart illustrating a method for mapping PUSCH repetitions according to some embodiments of this application. Although the method is performed by the UE and BS (e.g., such as...) Figure 1 The UE 102 and BS 101 described and shown are presented at the system level; however, those skilled in the art will understand that the methods implemented in the UE and the methods implemented in the BS can be implemented independently and can be combined by other devices with similar functions.

[0044] exist Figure 2 In the exemplary method shown, in step 201, on the network side, for example as Figure 1 The BS101 shown can transmit configuration information to the UE 102, for example, via RRC signaling and / or DCI. Correspondingly, in step 202, the UE 102 can receive configuration information from the BS 101. The configuration information indicates the mapping mode of multiple spatial relationship information and the number of nominal PUSCH repetitions for PUSCH transmission using multiple spatial relationship information. The PUSCH transmission can be PUSCH repetition type B transmission. The mapping mode of multiple spatial relationship information indicates the mapping between the configured spatial relationship information (beam) and the transmission unit of the time slot, nominal repetition, or actual repetition, which can be determined by the mapping scheme described below. For example, the mapping indicates which beam the UE uses to transmit each allocated time slot, each nominal repetition, or each actual repetition of the PUSCH transmission. The mapping mode of multiple spatial relationship information can be any mapping mode agreed upon by 3GPP, such as a cyclic mapping mode or a sequential mapping mode.

[0045] For example, given two spatial relationship information, such as spatial relationship information #1 and spatial relationship information #2, when the cyclic mapping mode is enabled, the first and second spatial relationship information are applied to the first and second transmission units respectively, and the same mapping mode continues to the remaining transmission units. Therefore, the cyclic mapping mode can be #1#2#1#2#1#2#1#2…. When the sequential mapping mode is enabled, the first spatial relationship information is applied to the first and second transmission units, and the second spatial relationship information is applied to the third and fourth transmission units, and the same TCI mapping mode continues to the remaining transmission units. Therefore, the sequential mapping mode can be #1#1#2#2#1#1#2#2….

[0046] In step 204, the UE may determine multiple actual PUSCH repeats based on the nominal number of PUSCH repeats using multiple spatial relationship information.

[0047] In step 206, multiple actual PUSCH repeats based on mapping modes and mapping schemes using multiple spatial relationship information can be transmitted. The mapping scheme can be one of the following: beam mapping by time slot, beam mapping by nominal repeat, and beam mapping by actual repeat. In other words, multiple actual PUSCH repeats are mapped to multiple spatial relationship information based on mapping modes, such as cyclic mapping or sequential mapping, and also based on beam mapping by time slot, beam mapping by nominal repeat, or beam mapping by actual repeat.

[0048] For example, in some embodiments of this application, when the mapping scheme is a time-slot-based beam mapping, the UE can associate each of the multiple allocated time slots for PUSCH transmission with corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode, and use the corresponding spatial relationship information associated with each individual time slot to transmit all actual PUSCH repetitions within the individual time slot. More specific embodiments can be seen in Figures 3(a) and 3(b), which will be described in detail below.

[0049] In some other embodiments of this application, when the mapping scheme is a nominal repeat beam mapping, the UE can associate each nominal PUSCH repeat transmitted with corresponding spatial relationship information in a plurality of spatial relationship information based on the mapping mode, and use the corresponding spatial relationship information associated with a single nominal PUSCH repeat to transmit all actual PUSCH repeats within each single nominal PUSCH repeat. More specific embodiments can be seen in Figures 4(a) and 4(b), which will be described in detail below.

[0050] In some other embodiments of this application, when the mapping scheme is based on actual repeating beam mapping, the UE can associate each of the multiple actual PUSCH repeats with the corresponding spatial relationship information in the multiple spatial relationship information based on the mapping mode. The corresponding spatial relationship information in the multiple actual PUSCH repeats and the multiple spatial relationship information are transmitted together based on the mapping mode. More specific embodiments can be seen in Figures 5(a) and 5(b), which will be described in detail below.

[0051] Similarly, on the network side, in step 203, the BS may determine, for example, multiple actual PUSCH repeats based on the nominal number of PUSCH repeats using multiple spatial relationship information. In step 205, the BS may receive multiple actual PUSCH repeats based on a mapping pattern and mapping scheme using multiple spatial relationship information. The mapping scheme used in the BS is consistent with the mapping scheme applied in the UE and may be one of the following: beam mapping according to time slots, beam mapping according to nominal repeats, and beam mapping according to actual repeats.

[0052] For example, in some embodiments of this application, when the mapping scheme is a beam mapping according to time slots, the BS can associate each of the multiple allocated time slots for PUSCH transmission with the corresponding spatial relationship information in the multiple spatial relationship information based on the mapping mode, and use the corresponding spatial relationship information associated with each individual time slot to receive all actual PUSCH repetitions within the individual time slot.

[0053] In some other embodiments of this application, when the mapping scheme is a beam mapping according to nominal repetition, the BS can associate each nominal PUSCH repetition of the PUSCH transmission with the corresponding spatial relationship information in a plurality of spatial relationship information based on the mapping mode, and use the corresponding spatial relationship information associated with each individual nominal PUSCH repetition to receive all actual PUSCH repetitions within the individual nominal PUSCH repetition.

[0054] In some other embodiments of this application, when the mapping scheme is based on actual repeating beam mapping, the BS can associate each of the multiple actual PUSCH repeats with the corresponding spatial relationship information in the multiple spatial relationship information based on the mapping mode. The BS will then receive the corresponding spatial relationship information in the multiple spatial relationship information together based on the mapping mode.

[0055] Figures 3(a) to 5(b) The mapping results of exemplary methods for mapping repetitions based on different mapping modes and mapping schemes, according to some embodiments of this application, are described respectively. Figures 3(a) to 5(b)For simplicity and clarity, this section only describes the two spatial relationship information and four nominal repetitions transmitted in PUSCH repetition type B. The two spatial relationship information can be two beams, such as beam 401 and beam 402. The four nominal repetitions are nominal repetition 2000, nominal repetition 2001, nominal repetition 2002, and nominal repetition 2003, and are transmitted in four time slots, such as time slot 1000, time slot 1001, time slot 1002, and time slot 1003. Furthermore, it is assumed that this PUSCH repetition type B transmission has six actual repetitions, namely actual repetition 3000, actual repetition 3001, actual repetition 3002, actual repetition 3003, actual repetition 3004, and actual repetition 3005.

[0056] From the perspective of time slots, actual repetition 3000 is in time slot 1000, actual repetitions 3001 and 3002 are in time slot 1001, actual repetitions 3003 and 3004 are in time slot 1002, and actual repetition 3005 is in time slot 1003.

[0057] From the perspective of nominal repetition, actual repetitions 3000 and 3001 are in nominal repetition 2000, actual repetitions 3002 and 3003 are in nominal repetition 2001, actual repetition 3004 is in nominal repetition 2002, and actual repetition 3005 is in nominal repetition 2003.

[0058] It should be noted that there may be other numbers of time slots, other numbers of nominal repetitions, and other numbers of actual repetitions, and the solution of this application is also applicable to scenarios with other numbers of time slots, nominal repetitions, and actual repetitions.

[0059] Specifically, Figure 3(a) illustrates the mapping results of an exemplary method for mapping repetitions based on a cyclic mapping pattern and beam mapping according to time slots, according to some embodiments of this application.

[0060] As stated above, when the mapping scheme is beam mapping according to time slots, the UE can associate each of the multiple allocated time slots used for PUSCH transmission with the corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode. Therefore, in Figure 3(a), based on the cyclic mapping mode, the first time slot, i.e., time slot 1000, is associated with spatial relationship information 401, such as beam 401; the second time slot, i.e., time slot 1001, is associated with spatial relationship information 402, such as beam 402; the third time slot, i.e., time slot 1002, is associated with spatial relationship information 401; and the fourth time slot, i.e., time slot 1003, is associated with spatial relationship information 402.

[0061] Furthermore, when the mapping scheme is beam mapping according to time slots, the corresponding spatial relationship information associated with each individual time slot is used to transmit all actual PUSCH repetitions within that individual time slot. Based on the above, time slots 1000 and 1002 are associated with spatial relationship information 401, and actual repetition 3000 is in time slot 1000, while actual repetitions 3003 and 3004 are in time slot 1002. Therefore, spatial relationship information 401 is used to transmit actual repetitions 3000, 3003, and 3004. Similarly, time slots 1001 and 1003 are associated with spatial relationship information 402, and actual repetitions 3001 and 3002 are in time slot 1001, while actual repetition 3005 is in time slot 1003. Therefore, spatial relationship information 402 is used to transmit actual repetitions 3001, 3002, and 3005.

[0062] This application also supports other numbers of spatial relationship information. For example, when there are three spatial relationship information, such as #1, #2, and #3, the cyclic mapping pattern is #1#2#3#1#2#3… Then time slot 1000 and time slot 1003 are associated with spatial relationship information #1, time slot 1001 is associated with spatial relationship information #2, and time slot 1002 is associated with spatial relationship information #3.

[0063] Figure 3(b) illustrates the mapping results of another exemplary method for mapping repetitions based on sequential mapping patterns and beam mapping according to time slots, according to some embodiments of this application.

[0064] Similarly, when the mapping scheme is beam mapping according to time slots, the UE can associate each of the multiple allocated time slots used for PUSCH transmission with the corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode. Therefore, in Figure 3(b), based on the sequential mapping mode, the first time slot, such as time slot 1000 and the second time slot, such as time slot 1001, are associated with spatial relationship information 401, such as beam 401, and the third time slot, such as time slot 1002 and the fourth time slot, such as time slot 1003, are associated with spatial relationship information 402.

[0065] Furthermore, when the mapping scheme is beam mapping according to time slots, the corresponding spatial relationship information associated with each individual time slot is used to transmit all actual PUSCH repetitions within that individual time slot. Based on the above, time slots 1000 and 1001 are associated with spatial relationship information 401, actual repetition 3000 is in time slot 1000, and actual repetitions 3001 and 3002 are in time slot 1001. Therefore, spatial relationship information 401 is used to transmit actual repetitions 3000, 3001, and 3002. Similarly, time slots 1002 and 1003 are associated with spatial relationship information 402, actual repetitions 3003 and 3004 are in time slot 1002, and actual repetition 3005 is in time slot 1003. Therefore, spatial relationship information 402 is used to transmit actual repetitions 3003, 3004, and 3005.

[0066] Figure 4(a) illustrates the mapping results of an exemplary method for mapping repetitions based on a cyclic mapping pattern and a beam mapping according to nominal repetition, according to some embodiments of this application.

[0067] As stated above, when the mapping scheme is a nominal repeating beam mapping, the UE can associate each nominal repeat with the corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode. Therefore, in Figure 4(a), based on the cyclic mapping mode, the first nominal repeat, i.e., nominal repeat 2000, is associated with spatial relationship information 401, such as beam 401; the second nominal repeat, i.e., nominal repeat 2001, is associated with spatial relationship information 402, such as beam 402; the third nominal repeat, i.e., nominal repeat 2002, is associated with spatial relationship information 401, such as beam 401; and the fourth nominal repeat, i.e., nominal repeat 2003, is associated with spatial relationship information 402, such as beam 402.

[0068] Furthermore, when the mapping scheme is beam mapping according to nominal repetitions, the corresponding spatial relationship information associated with each individual nominal repetition is used to transmit all actual PUSCH repetitions within that individual nominal repetition. Based on the above, nominal repetitions 2000 and 2002 are associated with spatial relationship information 401, such as beam 401, and actual repetitions 3000 and 3001 are in nominal repetition 2000, and actual repetition 3004 is in nominal repetition 2002. Therefore, spatial relationship information 401 is used to transmit actual repetitions 3000, 3001, and 3004. Similarly, nominal repetitions 2001 and 2003 are associated with spatial relationship information 402, such as beam 402, and actual repetitions 3002 and 3003 are in nominal repetition 2001, and actual repetition 3005 is in nominal repetition 2003. Therefore, spatial relationship information 402 is used to transmit actual repetitions 3002, 3003, and 3005.

[0069] This application also supports other numbers of spatial relationship information. For example, when there are three spatial relationship information, such as #1, #2, and #3, the cyclic mapping pattern is #1#2#3#1#2#3… Then, nominal repetition 2000 and nominal repetition 2003 are associated with spatial relationship information #1, nominal repetition 2001 is associated with spatial relationship information #2, and nominal repetition 2002 is associated with spatial relationship information #3.

[0070] Figure 4(b) illustrates the mapping results of another exemplary method for mapping repetitions based on sequential mapping patterns and beam mapping according to nominal repetitions, according to some embodiments of this application.

[0071] Similarly, when the mapping scheme is a beam mapping based on nominal repetition, the UE can associate each nominal repetition with the corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode. Therefore, in Figure 4(b), based on the sequential mapping mode, the first nominal repetition, i.e., nominal repetition 2000 and the second nominal repetition, i.e., nominal repetition 2001, are associated with spatial relationship information 401, such as beam 401; the third nominal repetition, i.e., nominal repetition 2002 and the fourth nominal repetition, i.e., nominal repetition 2003, are associated with spatial relationship information 402, such as beam 402.

[0072] Furthermore, when the mapping scheme is beam mapping according to nominal repeats, the corresponding spatial relationship information associated with each individual nominal repeat is used to transmit all actual PUSCH repeats within that individual nominal repeat. Based on the above, actual repeats 3000 and 3001 are in nominal repeat 2000, and actual repeats 3002 and 3003 are in nominal repeat 2001. Therefore, spatial relationship information 401 is used to transmit actual repeats 3000, 3001, 3002, and 3003. Similarly, actual repeat 3004 is in nominal repeat 2002, and actual repeat 3005 is in nominal repeat 2003. Therefore, spatial relationship information 402 is used to transmit actual repeats 3004 and 3005.

[0073] Figure 5(a) illustrates the mapping results of an exemplary method for mapping repetitions based on a cyclic mapping pattern and according to actual repetitive beam mapping according to some embodiments of this application.

[0074] As stated above, when the mapping scheme is based on actual repeating beam mapping, the UE can associate each actual repeat with the corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode. Therefore, in Figure 5(a), based on the cyclic mapping mode, the first actual repeat, i.e., actual repeat 3000, is associated with spatial relationship information 401, such as beam 401; the second actual repeat, i.e., actual repeat 3001, is associated with spatial relationship information 402, such as beam 402; the third actual repeat, i.e., actual repeat 3002, is associated with spatial relationship information 401, such as beam 401; the fourth actual repeat, i.e., actual repeat 3003, is associated with spatial relationship information 402, such as beam 402; the fifth actual repeat, i.e., actual repeat 3004, is associated with spatial relationship information 401, such as beam 401; and the sixth actual repeat, i.e., actual repeat 3005, is associated with spatial relationship information 402, such as beam 402.

[0075] In summary, spatial relationship information 401 is used to transmit actual repetitions 3000, 3002 and 3004; and spatial relationship information 402 is used to transmit actual repetitions 3001, 3003 and 3005.

[0076] This application also supports other numbers of spatial relationship information. For example, when there are three spatial relationship information, such as #1, #2, and #3, the cyclic mapping pattern is #1#2#3#1#2#3… Then, spatial relationship information #1 is associated with actual repeat 3000 and actual repeat 3003, spatial relationship information #2 is associated with actual repeat 3001 and actual repeat 3004, and spatial relationship information #3 is associated with actual repeat 3002 and actual repeat 3005.

[0077] Figure 5(b) illustrates the mapping results of another exemplary method for mapping repetitions based on sequential mapping patterns and beam mapping according to time slots, according to some embodiments of this application.

[0078] Similarly, when the mapping scheme is beam mapping by time slot, the UE can associate each of the multiple allocated time slots used for PUSCH transmission with the corresponding spatial relationship information in multiple spatial relationship information based on the mapping mode. Therefore, in Figure 5(b), based on the sequential mapping mode, the first actual repetition, i.e., actual repetition 3000 and the second actual repetition, i.e., actual repetition 3001, are associated with spatial relationship information 401, such as beam 401; the third actual repetition, i.e., actual repetition 3002 and the fourth actual repetition, i.e., actual repetition 3003, are associated with spatial relationship information 402, such as beam 402; and the fifth actual repetition, i.e., actual repetition 3004 and the sixth actual repetition, i.e., actual repetition 3005, are associated with spatial relationship information 401, such as beam 401.

[0079] In summary, spatial relationship information 401 is used to transmit actual repetitions 3000, 3001, 3004 and 3005; and spatial relationship information 402 is used to transmit actual repetitions 3002 and 3003.

[0080] This application also supports other numbers of spatial relationship information. For example, when there are three spatial relationship information, such as #1, #2, and #3, the cyclic mapping pattern is #1#1#2#2#3#3… Then, spatial relationship information #1 is associated with actual repeats 3000 and 3001, spatial relationship information #2 is associated with actual repeats 3002 and 3003, and spatial relationship information #3 is associated with actual repeats 3004 and 3005.
