Description

Technical Field

[0001] This disclosure generally relates to wireless communication, and more specifically, to a wireless communication method for duplex subbands. Background Technology

[0002] Wireless communication technology is a key component of the increasingly interconnected global communication network. Wireless communication relies on accurately allocated time-domain and frequency-domain resources to transmit and receive wireless signals. Frequency division duplex (FDD) and time division duplex (TDD) can better utilize wireless communication resources. In FDD mode, frequency-domain resources are divided for downlink and uplink. With continuous time-domain resources, FDD is characterized by lower latency, lower throughput, and dispersed spectrum bands. In TDD mode, time-domain resources are allocated between downlink and uplink, resulting in higher latency. TDD / FDD's fixed allocation of time-domain / frequency-domain resources has both advantages and limitations. Summary of the Invention

Detailed Implementation

[0012] While FD is a new technology to improve spectrum efficiency, simultaneous transmission on both the downlink (DL) and uplink (UL) can cause severe interference, potentially complicating the design of gNBs (base stations or BSs) and user equipment (UEs) and increasing costs. Therefore, in the early stages of 5G-Advanced, the focus will be on Subband Full-Duplex (SBFD), and then gradually expanded to FD networks suitable for gNBs and UEs.

[0013] The Synchronization Signal / PBCH block (SSB) includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH). According to some embodiments, SSBs can be divided into two types: Type 1 and Type 2. For example, if an SBFD subband (such as a subband including UL and DL subbands) is configured in a symbol of a Type 1 SSB, the UL subband in the symbol of the Type 1 SSB may be prohibited from use for UL transmission. Alternatively, if an SBFD subband is configured in a symbol of a Type 2 SSB, the UL subband in the symbol of the Type 2 SSB can still be allowed for UL transmission. It should be noted that "first" and "second" are merely exemplary designations and do not limit the scope of the invention. Regarding transmission repetition, PUSCH can also be divided into Type A and Type B. For PUSCH Type A with k repetitions, each repetition needs to be transmitted within one time slot. For example, PUSCH type A is configured to use 2 symbols and is configured to perform 4 repetitions. The first repetition is transmitted in symbols #0 and #1 of the valid time slot n. Assuming that time slots n+1, n+2, and n+3 are all valid time slots for PUSCH type A, the second repetition is transmitted in symbols #0 and #1 of time slot n+1, the third repetition is transmitted in symbols #0 and #1 of time slot n+2, and the fourth repetition is transmitted in symbols #0 and #1 of time slot n+3.

[0014] For PUSCH type B with k repetitions, valid symbols need to be determined based on certain conditions. Each repetition of PUSCH type B can be transmitted consecutively within the identified valid symbols. Valid symbols are determined in one or more time slots. For example, PUSCH type B is configured to use 2 symbols and is configured to perform 4 repetitions. The first repetition is transmitted in symbols #0 and #1 of time slot n. Assuming that symbols #0 through #13 in time slot n are valid symbols for PUSCH type B, the second repetition is transmitted in symbols #2 and #3 of time slot n, the third repetition is transmitted in symbols #4 and #5 of time slot n, and the fourth repetition is transmitted in symbols #6 and #7 of time slot n.

[0015] Configuration of Type I or Type II SSB Example 1: According to some embodiments of this disclosure, the BS can transmit a first parameter to the UE to indicate which SSBs are first-type SSBs within a half-frame duration (or SBFD configuration period). For example, the first parameter can use bitmap signaling. The number of bits in the first parameter corresponds to the number of SSBs configured within the half-frame duration. The number of bits in the first parameter can be equal to the number of SSBs configured within the half-frame duration. For example, each bit of the first parameter can be set to "1" to indicate that the corresponding SSB is a first-type SSB; alternatively, each bit of the first parameter can be set to "0" to indicate that the corresponding SSB is not a first-type SSB. Alternatively, each bit of the first parameter can be set to "0" to indicate that the corresponding SSB is a first-type SSB; each bit of the first parameter can be set to "1" to indicate that the corresponding SSB is not a first-type SSB.

[0016] During a half-frame duration, the number of SSBs configured can be 4, 8, or 64, depending on the situation. Based on the frame configuration, the number of bits in the bitmap signaling also corresponds to 4 bits, 8 bits, or 64 bits. The first parameter can be transmitted from the BS to the UE, and vice versa. Therefore, when the UE receives the first parameter configured by the BS, the UE can determine the presence of the first type of SSB and the second type of SSB.

[0017] Example 2. Alternatively or additionally, two parameters can be added. For ease of explanation, these two parameters can be referred to here as the second parameter and the third parameter. For example, the second parameter can be added to indicate the grouping of SSBs during the duration of an SSB burst, relative to the occurrence of a first-type or second-type SSB within the group. Similarly, the second parameter can use bitmap signaling. For example, the number of bits in the bitmap signaling can be 8 bits.

[0018] In some examples, SSBs can be grouped as follows. If the number of SSBs configured within a half-frame is 64, the indices can be represented as indices 0-63; then the first group includes SSBs {0-7}, the second group includes SSBs {8-15}, the third group includes SSBs {16-23}, and so on, dividing the 64 SSBs into 8 groups. These 8 groups correspond to the bitmap signaling of the parameters. According to some examples, if the number of SSBs within a half-frame duration is 4 or 8, then the second parameter is not necessarily 4 or 8.

[0019] For example, the second parameter can carry a first value, such as "1", or a second value, such as "0". The first value in the bitmap signaling indicates that at least one SSB in the corresponding group is a first type SSB, while the second value indicates that no SSB in the corresponding group is a first type SSB.

[0020] Furthermore, a third parameter can be added to indicate which SSBs in the corresponding SSB group are Type 1 SSBs (alternatively, or Type 2 SSBs), and which of the second parameters indicates the presence of at least one Type 1 SSB. For example, the third parameter can use bitmap signaling. The number of bits in this bitmap signaling can be equal to 8 bits, or otherwise the same as the number of bits in the SSB group. For example, a first value (e.g., "1") in the bitmap signaling can indicate that the corresponding SSB is a Type 1 SSB (alternatively, or not a Type 1 SSB), while a second value (e.g., "0") can indicate that the corresponding SSB is not a Type 1 SSB (alternatively, or a Type 1 SSB).

[0021] For example, according to the indication of the second parameter, the first and second groups of a half-frame can have one or more Type 1 SSBs. Accordingly, the second parameter can have signaling of "11000000". Furthermore, the third parameter can indicate the Type 1 SSB and the third SSB within each selected group. Accordingly, the third parameter can be 10100000. Therefore, the final index of the Type 1 SSB can be index 0, index 2, index 8, and index 10.

[0022] For example, if the number of SSBs configured within a half-frame is 8, the second parameter is not necessarily 8. In this case, each bitmap of the third parameter can correspond to one SSB in each group. If the number of SSBs configured within a half-frame is 4, then the second parameter is not needed. In this case, the lower 4 bits of the third parameter can be used, while the higher 4 bits can be omitted. For example, a value of 1 in the bitmap signaling indicates that the corresponding SSB is a Type 1 SSB, while a value of 0 indicates that the corresponding SSB is not a Type 1 SSB.

[0023] Parameters can be transmitted from the BS to the UE and vice versa. Therefore, when the UE receives the first parameter configured by the BS, the UE can determine the presence of a first type SSB and a second type SSB. This parameter can be used to determine the first type SSB, and it can also be used to determine the second type SSB, depending on the consensus between the BS and the UE regarding the type of SSB to be identified.

[0024] Example 3. Alternatively or additionally, the BS and UE may agree that the configuration of the SBFD subband (including the UL subband and DL subband) can be performed within a transmission period. The size and start point of the period can be aligned with the duration and start point of a half-frame. Alternatively or additionally, if the period of a frame is a combination of two short subframes, and the DL and UL slots in these two short frames are configured the same or different, then the SBFD subband configuration can be based on the frame period; the size and start point of the SBFD subband period can be aligned with the frame period and start point.

[0025] Additionally, a fourth parameter (alternatively or additionally) can be added in this case to indicate which SSBs are Type 1 SSBs (alternatively, or Type 2 SSBs) among all SSBs included in the configuration period of the SBFD subband. As an example, the fourth parameter can use bitmap signaling, and the number of bits in the bitmap signaling can correspond to or be equal to the number of SSBs included in the configuration period of the SBFD subband. For example, in the bitmap signaling, a first value (for example, "1") can indicate that the corresponding SSB is a Type 1 SSB; a second value (for example, "0") can indicate that the corresponding SSB is not a Type 1 SSB. This parameter can be used to determine Type 1 SSBs, and it can also be used to determine Type 2 SSBs, depending on the consensus between the BS and the UE regarding the type of SSB to be identified.

[0026] Therefore, the configuration periods of both SBFD subbands and SSBs can be aligned with half-frames, which is beneficial for including the same number and position of SSBs in each SBFD period, and also for the arrangement of the fourth parameter.

[0027] Example 4. Alternatively or additionally, a fifth parameter can be introduced to replace the fourth parameter to reduce signaling overhead. The fifth parameter can be used to indicate which SSBs in the configuration period are Type 1 SSBs (alternatively or additionally, or Type 2 SSBs) that overlap with the UL subband (in the DL slot) or have SBFD symbols. The fifth parameter can be bitmap signaling, and the number of bits in the bitmap signaling can correspond to or be equal to the number of SSBs overlapping with the UL subband or with SBFD symbols in the configuration period of the SBFD subband. For example, in bitmap signaling, a first value (e.g., "1") can indicate that the corresponding SSB is a Type 1 SSB; a second value (e.g., "0") can indicate that the corresponding SSB is not a Type 1 SSB (or is a Type 2 SSB). For example, see [reference]. Figure 1 The configuration period of the SBFD subband is aligned with the half-frame. According to Example 4, the bitmap signaling for the fifth parameter has 3 bits because there are 3 SSBs in the second, third, and second right slots from the left, and the SSBs (and within the DL slot) overlap with the UL subband or are SBFD symbols. On the other hand, according to Example 3, the bitmap signaling for the fourth parameter has 4 bits to indicate, such as... Figure 1 The four SSBs shown.

[0028] In Examples 1 through 4, an SSB can be defined as a CD-SSB (Center Dot-SSB) and / or an NCD-SSB (Non-Center Dot-SSB). That is, the parameters described above can further indicate which SSBs are first-type SSBs derived from CD-SSBs, which SSBs are first-type SSBs derived from NCD-SSBs, or which SSBs are first-type SSBs derived from both CD-SSBs and NCD-SSBs.

[0029] The above parameters can be transmitted from the BS to the UE and vice versa. Therefore, when the UE receives the parameters configured by the BS, the UE can determine the presence of a first type SSB and / or a second type SSB. These parameters can be used to determine the first type SSB, and they can also be used to determine the second type SSB, depending on the consensus between the BS and the UE regarding the type of SSB to be identified.

[0030] Example 5: According to some embodiments, if the symbol of the SSB is configured with SBFD subbands (including UL subbands and DL subbands), and if the UL transmission is scheduled or configured in the resources of the UL subband, the UL transmission can be performed according to at least one of the following examples.

[0031] First, the BS can use RRC (Radio Resource Control) signaling or DCI (Downlink Control Index) signaling to indicate whether the UE can perform UL transmission in the UL subband of the SSB symbol.

[0032] Example 5-1: Parameter A can be added to the DCI (Downlink Control Information), which can be transmitted from the BS to the UE. Parameter A indicates whether UL transmission is performed in the UL subband or whether it can be performed in the UL subband. If UL transmission is scheduled in the UL subband, the UE can determine whether to perform UL transmission based on parameter A in the DCI. That is, the UE can receive a DCI with parameter A and use the DCI to determine whether DL reception is performed or scheduled by the BS according to the indication of parameter A in the DCI.

[0033] Example 5-2: Additionally or alternatively, for a UE capable of performing UL transmissions in the UL subband of an SSB symbol, the BS can configure whether the UE performs UL transmissions in the UL subband of the SSB symbol via RRC (Radio Resource Control) signaling or DCI signaling. For example, suppose the UE is configured to perform UL transmissions in the UL subband via RRC signaling, and if the UL transmission is scheduled in the UL subband via DCI (which may or may not include parameter A above), then the UE can perform UL transmissions. Suppose the UE is not configured to perform UL transmissions in the UL subband via RRC signaling, and if the UL transmission is scheduled in the UL subband via DCI (excluding parameter A above), then the UE does not perform UL transmissions. That is, the BS can configure the UE using signaling (such as RRC signaling or DCI signaling). After receiving the signaling, the UE can determine whether the UL transmission is configured by the BS in the UL subband of the DL time slot based on the signaling.

[0034] Example 5-3: Additionally or alternatively, RRC signaling can be introduced. The BS can use RRC signaling to notify the UE to determine whether to perform a UL transmission in the UL subband based on parameter A in the DCI. If the UL transmission is scheduled in the UL subband by the DCI and parameter A is included in the DCI, the UE determines whether to perform the UL transmission based on the indication of parameter A.

[0035] Example 5-4: Additionally or alternatively, RRC signaling including two indication states can be introduced. When UL transmission is configured or scheduled in the UL subband, the first (or second) indication state can instruct the UE not to perform UL transmission. When UL transmission is scheduled in the UL subband, the second (or first) indication state can instruct the UE whether to perform UL transmission based on parameter A in the DCI. When UL transmission is scheduled in the UL subband, if the first indication state is configured for the UE by the BS, the UE will never perform UL transmission. When UL transmission is configured or scheduled in the UL subband, if the second indication state is configured for the UE by the BS, the UE determines whether to perform UL transmission based on parameter A in the DCI. For example, the BS can send signaling with both states. The UE can receive the signaling and use it to determine whether UL transmission is disabled or enabled. When UL transmission is configured or scheduled by the BS in the UL subband, the first state can disable the UE's UL transmission, even if the UL transmission is scheduled by the BS; and the second state allows the UE to perform UL transmission based on parameter A.

[0036] Example 5-5: Additionally or alternatively, the BS and UE may agree that if a high-priority UL transmission is scheduled by the DCI within a resource in the UL subband of the DL time slot, the UE may consider that resource to be valid. The UE performs the UL transmission, and the BS also considers the UE to have performed the UL transmission. Therefore, the UE determines whether to perform the UL transmission based on whether the BS has scheduled a high-priority UL transmission.

[0037] Example 5-6: Additionally or alternatively, the BS and UE may agree that if a high-priority semi-static UL transmission is configured in the resources of the UL subband of the DL time slot, the UE may consider the resource valid, but whether the UE performs the UL transmission depends on the UE's request, and the BS considers the resource valid.

[0038] Example 5-7: Additionally or alternatively, the BS and UE may agree that if a low-priority UL transmission is scheduled by the DCI in the UL subband of the DL time slot, the UE may consider that resource invalid and will not perform the UL transmission. The BS assumes the UE is not performing the UL transmission. The BS prohibits scheduling the UL transmission, and the UE does not expect to be scheduled for that UL transmission.

[0039] Example 5-8: Additionally or alternatively, the BS and UE may agree that if a low-priority UL transmission is scheduled by the DCI in the UL subband of the DL time slot, the UE may consider the resource valid, but the UE will not perform the UL transmission, and the BS also understands that the UE will not perform the UL transmission. The BS may prohibit scheduling of the UL transmission, and the UE does not expect to be scheduled for the UL transmission.

[0040] Example 5-9: Additionally or alternatively, the BS and UE may agree that if a low-priority semi-static UL transmission is configured in a resource of the UL subband, the UE may consider that resource invalid and will not perform the UL transmission. The BS understands that the UE will not perform the UL transmission. The BS may disable scheduling of the UL transmission, and the UE does not expect to be scheduled for that UL transmission.

[0041] Example 5-10: Additionally or alternatively, the BS and UE may agree that if a low-priority semi-static UL transmission is configured in a resource within the UL subband, the UE may consider that resource valid, but the UE will not execute the UL transmission. The BS considers the UE not to execute the UL transmission. The BS may prohibit scheduling of the UL transmission, and the UE does not expect to be scheduled for that UL transmission. In some of the examples above, the UE may determine whether a resource in the UL subband is valid, or whether a UL transmission can be executed, based on whether the scheduled UL transmission is high-priority or low-priority and whether it is semi-static. The BS and UE agree on the determination process and understand the UE's determination.

[0042] In Example 5, additionally or alternatively, the BS and UE may agree that if a UL transmission is not performed according to Examples 5-1 to 5-10 or a combination thereof, but the resource corresponding to the UL transmission is considered valid, then that resource may be counted in the number of valid resources. Alternatively, the BS and UE may agree that if a UL transmission is not performed according to Examples 5-1 to 5-10 or a combination thereof, then the resource corresponding to the UL transmission will not be counted in the number of valid resources.

[0043] Example 6, Repeated Transmission Additionally or alternatively, this section of the present disclosure, among other examples, discusses scheduling repetitive transmissions when scheduling within one or more Type 1 or Type 2 SSBs in an SBFD subband. For example, a repetitive transmission includes a PUSCH transmission corresponding to a TB (Transmission Block). A single transmission of a TB occurs in slots across N time slots, and the TB is repetitively transmitted k times. Here, N can be an integer greater than or equal to 1. For example, if a TB corresponding to a PUSCH requires one time slot for transmission, then k repetitions of the PUSCH require k time slots. If a TB corresponding to a PUSCH requires two time slots for transmission, then k repetitions of the PUSCH require 2 time slots. k time slots.

[0044] Example 6-1, Alternatively or additionally, the BS and UE may agree that, for PUSCH type A with k repetitions, if the UE is configured to determine N via RRC message... k time slots, then N The number of k time slots can be determined based on the UL subband configuration, SSB type, and / or PUSCH symbol.

[0045] Example 6-1-1: Alternatively or additionally, as an example, for a PUSCH type A with k repetitions, if the SBFD subband (including the UL subband and / or DL ​​subband) is configured in the symbols of the first type SSB in a time slot (e.g., the DL time slot), and at least one symbol of the PUSCH overlaps with a symbol of the first type SSB in the time domain, then the time slot is not counted in N. In k time slots. That is to say, N The k time slots do not include those that satisfy the above condition. Otherwise, time slots that do not satisfy this condition can be included in N. In k time slots. That is, if an SBFD subband is configured in a symbol of a first type SSB in a time slot, and (if configured) at least one symbol of a PUSCH overlaps with a symbol of a first type SSB in the time domain, then PUSCH is not allowed to be transmitted in that time slot.

[0046] Alternatively or additionally, the frequency domain resources of PUSCH can be configured based on UL subbands; the frequency domain resources of PUSCH can be located within UL subbands.

[0047] Example 6-1-2: As an example, additionally or alternatively, for a PUSCH type A with k repetitions, in a time slot, if an SBFD subband (including UL subband and / or DL ​​subband) is configured in a symbol of a first type SSB, and at least one symbol of the PUSCH overlaps with a symbol of a first type SSB in the time domain, then the time slot is counted in N. k time slots. That is, N The k time slots include those that satisfy the above conditions. That is, if in a time slot, an SBFD subband (including UL subband and / or DL ​​subband) is configured in a symbol of a Type 1 SSB, and at least one symbol of the PUSCH overlaps with a symbol of a Type 1 SSB in the time domain, then PUSCH transmission is not allowed in that time slot. However, whether PUSCH can ultimately be transmitted depends on other conditions. Here, the frequency domain resources of the PUSCH are configured based on the UL subband; that is, the frequency domain resources of the PUSCH are located within the UL subband. Otherwise, time slots that do not meet this condition cannot be included in N. In k time slots.

[0048] Example 6-1-3: As an example, additionally or alternatively, for a PUSCH type A with k repetitions, if in a time slot at least one symbol of the PUSCH overlaps in the time domain with a symbol of a first type SSB or a DL symbol of an unconfigured SBFD subband, then that time slot is not counted in N. In k time slots. That is to say, N The k time slots do not include this time slot. Otherwise, time slots that do not meet the above conditions can be included in N. Within k time slots. That is, if at least one symbol of a PUSCH overlaps in the time domain with a Type 1 SSB symbol or a DL symbol of an unconfigured SBFD subband, PUSCH transmission is not permitted in the time slot. PUSCH can be scheduled via DCI or configured via RRC signaling. DL symbols can be configured via tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. Furthermore, symbols of Type 1 SSBs can be configured as SBFD subbands. Type 1 SSBs are part of SBFD subbands. Additionally, the frequency domain resources of PUSCH can be configured based on UL subbands; that is, the frequency domain resources of PUSCH can reside within UL subbands.

[0049] Example 6-1-4: As an example, additionally or alternatively, for a PUSCH type A with k repetitions, if at least one symbol of the PUSCH overlaps with a symbol of the SSB in the time domain within a candidate time slot, then, for example, based on BS signaling, at least one of the following configurations can be set: (1) If the symbol of the SSB is not configured with an SBFD subband (assuming the SSB is not classified as a Type I SSB or a Type II SSB), then the candidate slot is not counted in N. k time slots; that is, N The k time slots do not include candidate time slots. That is, if at least one symbol of the PUSCH overlaps with a symbol of the SSB in the time domain, and the SSB symbol is not configured with an SBFD subband, then PUSCH transmission in a candidate time slot is not permitted; and / or (2) If the symbol of the SSB is configured with an SBFD subband (assuming the SSB is not classified as a Type I SSB or a Type II SSB), then the candidate slot is counted in N. k time slots; that is, N The k time slots include the time slots. That is, if at least one symbol of the PUSCH overlaps with a symbol of the SSB in the time domain, and the symbol of the SSB is configured with an SBFD subband, then the PUSCH is allowed to be transmitted in the candidate time slot; and / or (3) If the symbol of the SSB is configured with an SBFD subband and the SSB is a Type I SSB, then the candidate slot is not counted in N. k time slots. That is, N The k time slots do not include candidate time slots. That is, if at least one symbol of the PUSCH overlaps with a symbol of the SSB in the time domain, the SSB symbol is configured with an SBFD subband, and the SSB is a Type 1 SSB, then PUSCH transmission in a candidate time slot is not permitted; and / or (4) If the symbol of the SSB is configured with an SBFD subband and the SSB is a second type SSB, then the candidate slot is counted in N. k time slots; that is, N The k time slots include candidate time slots. That is, if at least one symbol of the PUSCH overlaps with a symbol of the SSB in the time domain, the symbol of the SSB is configured with an SBFD subband, and the SSB is a second type SSB, then the PUSCH is allowed to be transmitted in the candidate time slot.

[0050] The frequency domain resources of PUSCH can be configured based on UL subbands; that is, the frequency domain resources of PUSCH can be located within UL subbands.

[0051] Example 6-1-5: As an example, additionally or alternatively, for a PUSCH type A with k repetitions, if in a candidate time slot, at least one symbol of the PUSCH overlaps with a UL symbol, F symbol, DL symbol of a configured SBFD subband, or a symbol of a second type SSB of a configured SBFD subband, then the candidate time slot is counted in N. k time slots; that is, N The candidate time slot is included in the k time slots. That is, if at least one symbol of the PUSCH overlaps with a UL symbol, F symbol, DL symbol of the configured SBFD subband, or a symbol of a second type SSB of the configured SBFD subband, the PUSCH is allowed to be transmitted in the candidate time slot. However, whether the PUSCH can ultimately be transmitted depends on other conditions.

[0052] Furthermore, PUSCH can be scheduled via DCI or configured via RRC signaling. UL symbols, F symbols, or DL ​​symbols can be configured via tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. Additionally, symbols of Type I SSBs are configured with SBFD subbands. Type I SSBs can be part of an SSB. PUSCH frequency domain resources can be configured based on UL subbands; that is, PUSCH frequency domain resources can reside within UL subbands.

[0053] Example 6-2: As an example, additionally or alternatively, the BS and UE may agree that, for PUSCH type A with k repetitions, if the UE is configured to determine N via RRC message... k time slots, then N The number of k time slots can be determined based on the UL subband configuration and the symbol of the PUSCH.

[0054] For example, for PUSCH type A with k repetitions, if at least one symbol of the PUSCH overlaps with a DL symbol in the time domain within a candidate time slot, then, for example, BS-based signaling, at least one of the following configurations can be set: (1) If the DL symbol is not configured with an SBFD subband, the candidate time slot is not counted in N. k time slots; that is, N The k time slots do not include candidate time slots. That is, if at least one symbol of the PUSCH overlaps with a DL symbol in the time domain, and that DL symbol is not configured with an SBFD subband, then the PUSCH is not allowed to be transmitted in a candidate time slot; and / or (2) If the DL symbol is configured with an SBFD subband, then the candidate time slot is counted in N. k time slots; that is, N The k time slots include the time slots. That is, if at least one symbol of the PUSCH overlaps with a DL symbol in the time domain, and that DL symbol is not configured with an SBFD subband, then the PUSCH is allowed to be transmitted in the candidate time slot.

[0055] Here, the frequency domain resources of PUSCH can be configured based on the UL subband; that is, the frequency domain resources of PUSCH can be located within the UL subband.

[0056] For the example above, if the UE or BS agrees that a specific timeslot is not included in N... With k time slots, the BS can avoid scheduling PUSCH repartitioning in this time slot, while the UE expects that there will be no PUSCH repartitioning scheduling in this time slot.

[0057] Example 7, Resources used for UL transmission For a first type SSB or a second type SSB determined according to Examples 1 to 4 above, if the symbol of the SSB is configured with SBFD subbands (including UL subbands and DL subbands), UL transmission can be performed according to at least one of the following conditions, especially when the UL transmission is a configured semi-static UL transmission.

[0058] Example 7-1: The BS and UE may agree that, for scheduled or configured UL transmissions (including repetitions), if at least one symbol of the UL transmission overlaps with a symbol of a Type 1 SSB in the time domain, the UE will not perform the UL transmission. Here, this does not apply regardless of whether the symbol of the Type 1 SSB is configured as an SBFD subband.

[0059] Example 7-2: Alternatively or additionally, the BS and UE may agree that, for scheduled or configured UL transmissions (including repetitions), UL transmissions are permitted to proceed if at least one symbol of the UL transmission overlaps with a symbol of a Type II SSB in the time domain. Here, the symbol of the Type II SSB is configured as an SBFD subband.

[0060] Example 7-3: Alternatively or additionally, the BS and UE may agree that, for scheduled or configured UL transmissions (with or without repetition), if the start symbol of the UL transmission follows the end of the SSB, and there exists such... Figure 2A The gap shown, for example, can be configured using BS-based signaling, at least one of the following configurations: (1) Alternatively or additionally, if the SSB is determined to be a Type 1 SSB, and the symbol of the SSB is configured with an SBFD subband, and the gap is greater than or equal to the gap threshold, then the BS considers UL transmission permitted, and the UE is permitted to perform UL transmission. That is, the resources for UL transmission are valid; (2) Alternatively or additionally, if the SSB is determined to be a Type 1 SSB, and the SSB symbol is configured with an SBFD subband and the gap is less than the gap threshold, then the BS considers UL transmission not permitted, and the UE is not permitted to perform UL transmission. That is, the resources for UL transmission are invalid; and / or (3) Alternatively or additionally, if the SSB is determined to be a Type II SSB and the symbol of the SSB is configured with an SBFD subband, the BS considers UL transmission permitted and the UE is permitted to perform UL transmission. The gap size is not considered. That is, the resources for UL transmission are valid regardless of the presence or absence of a gap.

[0061] Example 7-4: Alternatively or additionally, the BS and UE may agree that, for scheduled or configured UL transmissions (with or without repetition), if the end symbol of the UL transmission precedes the start symbol of the SSB, and there exists a condition such as... Figure 2B The gap shown, for example, can be configured using BS-based signaling, at least one of the following configurations: (1) Alternatively or additionally, if the SSB is determined to be a Type 1 SSB, and the symbol of the SSB is configured with an SBFD subband, and the gap is greater than or equal to the gap threshold, then the BS considers UL transmission to be permitted, and the UE is permitted to perform UL transmission. That is, the resources for UL transmission are valid.

[0062] (2) Alternatively or additionally, if the SSB is determined to be a Type 1 SSB, and the symbol of the SSB is configured with an SBFD subband and the gap is less than the gap threshold, then the BS considers UL transmission not permitted, and the UE is not permitted to perform UL transmission. That is, the resources for UL transmission are invalid.

[0063] (3) Alternatively or additionally, if the SSB is determined to be a Type II SSB and the symbol of the SSB is configured with an SBFD subband, the BS considers UL transmission permitted and the UE is permitted to perform UL transmission. No gap is required between the BS and the UE to agree that UL transmission is permitted. That is, the resources for UL transmission are valid.

[0064] Alternatively or additionally, the gap threshold in the different examples above can be related to the subcarrier spacing (SCS). For example, when the SCS is less than or equal to 120 kHz, the gap threshold can correspond to 2 symbols. When the SCS is equal to 480 kHz, the gap threshold can correspond to 8 symbols. When the SCS is equal to 960 kHz, the gap threshold can correspond to 16 symbols. Alternatively or additionally, the above UL transmissions include semi-static PUSCH / PUCCH (Physical Uplink Control Channel) / SRS (Sounding Reference Signal) and dynamically scheduled PUSCH / PUCCH / SRS.

[0065] In the example above, the BS can use configuration signaling to set specific configurations for the UE to establish one or more rules to determine the validity of UL transmission resources. Based on the configuration signaling settings, the UE can reach an agreement with the BS to determine whether UL transmission is allowed in the corresponding UL subband.

[0066] Example 8: Type B PUSCH repeated transmission For a first-type SSB or a second-type SSB determined according to Examples 1 to 4, if the SSB symbol is configured with SBFD subbands (including UL subbands and DL subbands), the valid symbol for a PUSCH type B with k repetitions can be determined based on at least one of the following conditions. For example, the BS and UE can agree that for a type B-BPUSCH with k repetitions, the valid symbol for the PUSCH can be determined based on the SBFD subband configuration and / or the SSB type.

[0067] For example, for a Type B PUSCH resource with k repetitions, if the PUSCH resource includes symbols of an SSB configured with an SBFD subband, the BS and UE agree to determine the valid symbols for the PUSCH based on the following conditions: (1) If the SSB is determined to be a Type I SSB, then the symbol of a Type I SSB configured with an SBFD subband is invalid for Type B PUSCH; or (2) Additionally or alternatively, if the SSB is determined to be a second type SSB, the symbol of the SSB configured with the SBFD subband is valid for type B PUSCH.

[0068] For example, for a Type B PUSCH resource with k repetitions, if the PUSCH resource includes DL symbols, the BS and UE can agree that the valid symbols used for the PUSCH are determined based on at least one of the following conditions: (1) If a DL symbol is configured with an SBFD subband, then the DL symbol is valid for type B PUSCH; or (2) If the DL symbol is not configured with an SBFD subband, the DL symbol is invalid for type B PUSCH.

[0069] As explained above, the UE's configuration can be set via, for example, signaling from the BS, enabling the BS and UE to agree on the actions and processing of the aforementioned conditions. Thus, the UE and BS can understand the actions and decisions that the other end will take.

[0070] Example 9: Use of UL sub-band in SBFD sub-band This section discusses topics including how to use UL sub-bands with SBFD sub-bands under different conditions. Based on some examples, the following rules have been established regarding the maximum number of transition points between SBFD and non-SBFD symbols.

[0071]

[0072] For a first-type or second-type SSB determined according to Examples 1 to 4, if the SSB symbol is configured with SBFD subbands (including UL subbands and DL subbands), the UL subband resources in the SSB symbol can be used based on at least one of the following examples. The use of SBFD subbands can be discussed in the following two cases.

[0073] Example 9-1, This disclosure first discusses, as Figure 3 The first type SSB or the second type SSB shown does not overlap with the UL sub-band. For example... Figure 3As shown, the frequency domain resources of the SSB configured by the BS do not overlap with the frequency domain of the UL subband. In this case, the frequency domain resources of the SSB can be located in the gaps between the DL subband and / or the frequency domain, but cannot be located in the frequency domain resources of the UL subband. In Example 9-1, if the SSB is determined to be a first-type SSB, the resources of the UL subband in the first-type SSB symbol are not allowed for UL transmission, and the resources of the UL subband in the first-type SSB symbol are allowed for DL ​​reception / transmission. To further improve the efficiency of the UL subband resources, at least one of the following examples can be configured between the BS and the UE for radio transmission: Example 9-1-1: Additionally or alternatively, the BS and UE may agree that if the SSB is determined to be a Type 1 SSB, DL reception is permitted in the resources of the UL subband (or the frequency domain gap between the UL subband and the DL subband) of the Type 1 SSB symbol. Switching points caused by DL reception (including switches from SBFD symbols to non-SBFD symbols and from non-SBFD symbols to SBFD symbols) are not counted in the agreed maximum number of switching points.

[0074] Example 9-1-2, Additionally or alternatively, the BS and UE may agree that if the SSB is determined to be a Type 1 SSB, the DL transport block (TB) corresponding to the DL reception is allowed to use resources in the UL subband of the Type 1 SSB symbol. Specifically, the resources of the DL TB may be located in the resources of the UL subband; Additionally or alternatively, the RB (Resource Block) for the DL TB may span the DL subband and the UL subband in the frequency domain; Additionally or alternatively, a portion of the frequency domain resources for the DL TB may be located in the DL subband, and another portion may be located in the UL subband.

[0075] Example 9-1-3, Additionally or alternatively, the BS and UE agree that, if the SSB is determined to be a Type 1 SSB, and if the DLRBG (Resource Block Group) (or PRG (Polarization Reuse Group) of PDSCH, or CSI-RS (Channel State Information Reference Signal) resource, or CORESET (Control Resource Set), or RBG or CSI (Channel State Information) reporting subband for CORESET) spans the DL subband and UL subband in the frequency domain, then the DL RBG (or PRG, or CSI-RS resource, or CORESET, or RBG or CSI reporting subband for CORESET) for PDSCH is valid. In other words, some resources in the DL RBG (or PRG, or CSI-RS, or CORESET, or RBG or CSI report subband) of the UL subband are valid.

[0076] Example 9-1-4, Additionally or alternatively, the BS and UE agree that if an SSB is determined to be a Type 1 SSB and the symbol of the SSB is configured with an SBFD subband, then the symbol of the SSB is considered to be an SSB symbol not configured with an SBFD subband; that is, an SSB symbol configured with an SBFD subband is converted to an SSB symbol not configured with an SBFD subband for DL ​​reception.

[0077] Example 9-1-4-1: Currently, to simplify UE complexity, DL reception or UL transmission may be prohibited from spanning both SBFD and non-SBFD symbols in a single time slot. Assume PDSCH corresponds to symbols 5-13, where symbols of the first type SSB are symbols 5-8, and the symbols of the first type SSB are configured with SBFD subbands, while symbols 9-13 are not configured with SBFD subbands. Based on the current setup, PDSCH cannot be transmitted because it spans both SBFD and non-SBFD symbols in a single time slot. To fully utilize resources in the UL subbands of the first type SSB symbols, at least one of the following rules or configurations (or combinations thereof) can be established between the BS and the UE.

[0078] Additionally or alternatively, according to this example, assume that DL reception is configured or scheduled in a time slot, and the symbols for DL ​​reception include SSB symbols, and the SSB symbols are configured with SBFD subbands. If the SSB is determined to be a first-type SSB, the SSB symbols can be converted to non-SBFD symbols to perform DL reception. Therefore, symbols 5-8 of the first-type SSB in the example above are converted to non-SBFD symbols. Therefore, symbols 5-13 of the PDSCH are considered non-SBFD symbols, and thus DL reception corresponding to the PDSCH can be performed in that time slot.

[0079] like Figure 4A and 4B As shown, DL channels or signals can be transmitted using both non-SBFD symbols and SBFD symbols. Since SBFD symbols are symbols of Type 1 SSBs, symbols of Type 1 SSBs configured with SBFD subbands are converted to non-SBFD symbols. Symbols of Type 1 SSBs configured with SBFD subbands are considered non-SBFD symbols.

[0080] Example 9-1-4-2: Based on the current equipment, the following conclusions can be drawn. For DL ​​reception spanning SBFD and non-SBFD symbols in different time slots (each DL reception within a time slot has all SBFD or all non-SBFD symbols), the following two options are provided. Non-SBFD symbols refer to symbols that are not configured with SBFD subbands.

[0081]

[0082] Additionally or alternatively, according to this example, if the SSB is determined to be a Type 1 SSB, and if DL repetition is performed across SBFD and non-SBFD symbols in different time slots, the BS and UE agree that the symbols of the Type 1 SSB configured with SBFD subbands are converted to non-SBFD symbols to perform DL repetition based on Option 1 or Option 2 above. DL repetition includes at least one of the following: PDSCH repetition, SPS PDSCH, multiple PDSCH scheduled by a single DCI, periodic / semi-persistent CSI-RS, PDCCH (Physical Downlink Control Channel), or DL ​​DMRS (Demodulation Reference Signal).

[0083] Additionally or alternatively, according to this example, if a PDSCH with k repetitions is configured or scheduled, and the PDSCH is executed based on option 1 or option 2 above, and the SSB symbol is configured with SBFD subband, then the BS and UE may agree that if the SSB is determined to be a first type SSB, the symbol of the first type SSB configured with SBFD subband is converted to a non-SBFD symbol so that different repetitions of the PDSCH can be transmitted based on option 1 or option 2.

[0084] For example, based on option 1, if the first n repetitions of PDSCH (n greater than or equal to 1) all use non-SBFD symbols, the remaining repetitions of PDSCH can use the first type SSB symbols of the configured SBFD subband, since the first type SSB symbols have been converted to non-SBFD symbols. Figure 5A and 5B as well as Figure 6A and 6B An exemplary description is provided in which the frequency domain resources of the DL channel or signal are not... Figure 5A and Figure 5B Within the UL subband, but the downlink channel or signal is... Figure 6A and Figure 6B Within the UL sub-band. In Figure 5A and Figure 6A In option 1, since at least one DL channel or signal is not in the SBFD symbol, the remaining DL channels or signals cannot use the SBFD symbol with the SSB symbol in the left fifth time slot. Figure 5B and 6B In Option 1, with the aforementioned improvements, since the first type SSB symbols are converted to non-SBFD symbols, the third DL channel or signal can be allocated in the fifth time slot on the left. Resources can be utilized more efficiently.

[0085] Additionally or alternatively, based on option 1, if the first n repetitions of PDSCH are all on SBFD symbols, the remaining repetitions of PDSCH cannot use the first type SSB symbols of the configured SBFD subband, because the first type SSB symbols are converted to non-SBFD symbols. Figure 7A and 7B An example is shown. Figure 7A In this context, Type 1 SSB symbols are not converted to non-SBFD symbols, therefore the third DL signal or channel can still be allocated in the fifth time slot from the left. Figure 7B In this case, because the first type SSB symbol is converted to a non-SBFD symbol in the fifth time slot, the third DL signal or channel needs to skip the fifth time slot from the left.

[0086] Additionally or alternatively, assuming that the DCI schedules multiple PDSCHs and executes multiple PDSCHs based on option 1 or option 2 above, and that SSB symbols are configured with SBFD subbands, the BS and UE may agree that if the SSB is determined to be a first type SSB, the symbol of the first type SSB configured with SBFD subbands is converted to a non-SBFD symbol so as to transmit different PDSCHs among the multiple PDSCHs based on option 1 or option 2.

[0087] For example, based on option 1, if the first n (n greater than or equal to 1) of multiple PDSCHs are all in non-SBFD symbols, the remaining PDSCHs of the multiple PDSCHs can use the first type SSB symbols of the configured SBFD subband, since the first type SSB symbols have been converted to non-SBFD symbols.

[0088] For example, based on option 1, if the first n PDSCHs of multiple PDSCHs are all in SBFD symbols, then the remaining PDSCHs of the multiple PDSCHs cannot use the first type SSB symbols of the configured SBFD subband, because the first type SSB symbols have been converted to non-SBFD symbols.

[0089] Additionally or alternatively, if a periodic downlink channel / signal is configured (including at least one of SPS PDSCH (Semi-Persistent Scheduling Physical Downlink Shared Channel), CORESET (Control Resource Set) for PDCCH (Physical Downlink Control Channel), or CSI-RS (Channel State Information Reference Signal), and the periodic downlink channel / signal is executed based on Option 1 or Option 2 above, and the SSB symbol is configured with SBFD subband, then the BS and UE agree that if the SSB is determined to be a first type SSB, the symbol of the first type SSB configured with SBFD subband is converted to a non-SBFD symbol so that the downlink channel / signal can be transmitted at different periodic positions based on Option 1 or Option 2.

[0090] For example, based on option 1, if all downlink channels or signals in the first n period positions are on non-SBFD symbols, then the downlink channels or signals in the remaining period positions can use the first type SSB symbols of the configured SBFD subband, because the first type SSB symbols are converted to non-SBFD symbols.

[0091] For example, based on option 1, if all downlink channels or signals in the first n period positions are SBFD symbols, then the downlink channels or signals in the remaining period positions cannot use the first type SSB symbols of the configured SBFD subband, because the first type SSB symbols are converted to non-SBFD symbols.

[0092] In the above examples, if the SSB is determined to be a second type SSB and the second type SSB symbol is configured with SBFD subbands (including UL subbands and DL subbands), then the resources of the UL subband in the second type SSB symbol are not allowed to be used for DL ​​reception, and based on the above examples 5 to 8, the resources of the UL subband in the second type SSB symbol are used for UL reception.

[0093] Example 9-1-5, alternatively or additionally, the BS and UE may agree that if the SSB is determined to be a Type II SSB, and the DL RBG (resource block group) used for PDSCH (or PRG for PDSCH, or CSI-RS resource, or CORESET, or RBG or CSI report subband for CORESET) spans the DL subband and UL subband in the frequency domain, then some resources in the UL subband that are part of the DL RBG (or PRG, or CSI-RS, or CORESET, or RBG, or CSI report subband) are considered invalid.

[0094] Example 9-2: Here, this disclosure discusses the case where the frequency domain resources of (one or more) SSBs overlap with the frequency domain resources of UL subbands in the frequency domain, such as... Figures 8A-8C As shown.

[0095] According to Example 9-2, if an SSB is determined to be a Type 1 SSB and the Type 1 SSB symbol is configured with SBFD subbands (including UL subbands and DL subbands), then the resources of the UL subband in the Type 1 SSB symbol are not allowed to be used for UL transmission, while the resources of the UL subband are used for DL ​​reception.

[0096] Therefore, in this case, the same operations or configurations as described in Examples 9-1, 9-1-2, 9-1-3 and 9-1-4 (including Examples 9-1-4-1 and 9-1-2) can be applied.

[0097] Additionally or alternatively, according to Example 9-2, if the SSB is determined to be a Type II SSB, and the Type II SSB symbol is configured with SBFD subbands (including UL subbands and DL subbands), then the resources of the UL subband in the Type II SSB symbol are not permitted for UL transmission, and the resources of the UL subband are used for DL ​​reception. Similarly, in this case, the same operation or configuration as described in Examples 9-1-1, 9-1-2, 9-1-3, and 9-1-4 (including Examples 9-1-4-1 and 9-1-2) can be applied.

[0098] Additionally or alternatively, according to Example 9-2, if the SSB is determined to be a Type II SSB, and the Type II SSB symbol is configured with an SBFD subband (including a UL subband and a DL subband), then resources in the UL subband other than those for the SSB are not permitted for DL ​​reception, and resources in the UL subband other than those for the SSB are used for UL transmission. Therefore, the operation or configuration described in 9-1-5 can be applied.

[0099] Note that while the operations or configurations in Examples 6-9 are described using Type 1 SSBs as examples, these operations or configurations also apply if Type 1 SSBs are replaced with Type 2 SSBs. Similarly, while the operations or configurations in Examples 6-9 are described using Type 1 SSBs as examples, these operations or configurations also apply when either Type 1 or Type 2 SSBs are replaced with unclassified SSBs. Furthermore, the specific steps for determining the type of SSB(s)(one or more) can be omitted.

[0100] It should be noted that this disclosure covers various aspects of related wireless transmission technologies and their improvements, and for the purpose of organizing this disclosure, these aspects are identified by different sections or example numbers. However, such identification or numbering of examples should not be construed as treating different examples as separate and unrelated. Rather, these examples, or specific aspects of these examples, can be combined together, which is also covered in the invention of this disclosure. Furthermore, each of the different examples disclosed herein can be separated as an independent invention to improve the performance of wireless communication systems, and the dependencies mentioned in this disclosure or the exemplary claims should not be used to limit the scope of the different aspects of the invention of this disclosure.

[0101] This disclosure discloses various configurations, agreements, or operations between the BS and the UE. Configurations can be made by the BS via configuration messages, which the corresponding UE can receive and configure. Thus, the BS and UE can understand or predict their respective determinations of the various radio transmission resources mentioned in the examples above. Furthermore, the UE and BS can perform UL or DL ​​radio transmissions according to the configurations described in the examples above or combinations thereof.

[0102] According to some embodiments of this disclosure, a wireless communication method is disclosed. The method includes: receiving a first parameter from a base station (BS), wherein the first parameter indicates the characteristics of one or more synchronization signal blocks (SSBs) within a period.

[0103] According to some embodiments of this disclosure, another wireless communication method is disclosed. The method includes: transmitting a first parameter by a base station (BS), wherein the first parameter indicates characteristics of one or more synchronization signal blocks (SSBs) within a period.

[0104] According to some examples, the first parameter indicates one or more first-type SSBs from a plurality of SSBs in the SBFD symbol within the period, and / or indicates whether one or more SSBs in the period are of the first type, wherein the SBFD symbol is a symbol configured with an SBFD subband, and the SBFD subband includes a UL subband.

[0105] According to some examples, the bit length of the first parameter corresponds to the number of multiple SSBs from SBFD symbols within the period.

[0106] According to some examples, if the symbol of an SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 1, then the resources of the UL subband are permitted for downlink (DL) reception.

[0107] According to some examples, conversions generated by resources of the UL subband that are permitted for DL ​​reception are not counted in the maximum threshold number of conversions between non-SBFD symbols and SBFD symbols, wherein the conversions include conversions from the SBFD symbols to the non-SBFD symbols and conversions from the non-SBFD symbols to the SBFD symbols.

[0108] According to some examples, if the SSB symbol is configured as an SBFD sub-band with a UL sub-band, and the SSB is of type 1, Resources of a DL conversion block (TB) are allowed to be located in the resources of the UL subband; resource blocks (RBs) of a DL TB are allowed to span the DL subband and the UL subband in the frequency domain; or a portion of the frequency resources of a DL TB are located in the DL subband, and another portion of the frequency resources of the DL TB are located in the UL subband.

[0109] According to some examples, if the symbol of the SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 1, and at least one of the following spans the DL subband and the UL subband: the DL resource block group RBG for the Physical Downlink Shared Channel (PDSCH), the polarization multiplexing group PRG for the PDSCH, the channel state information reference signal (CSI-RS) resource, the control resource set (CORESET), the resource block group RBG for the CORESET, or the CSI report subband, then the DL RBG for the PDSCH, the PRG for the PDSCH, the CSI-RS resource, the CORESET, and the RBG or CSI report subband for the CORESET are considered valid.

[0110] According to some examples, if the symbol of an SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 1, then the symbol of the SSB is considered not to be configured with an SBFD subband.

[0111] According to some examples, if the symbol of an SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 1, then the symbol of the SSB is converted to a non-SBFD symbol, wherein the one or more non-SBFD symbols are symbols that are not configured with any SBFD subband.

[0112] According to some examples, the method also includes receiving one or more PDSCH repetitions in one or more non-SBFD symbols of a transformation.

[0113] According to some examples, the method also includes receiving or transmitting all PDSCH repeats that do not overlap with one or more non-SBFD symbols of the conversion.

[0114] According to some examples, the method also includes receiving or transmitting at least one occurrence of a periodic DL channel or signal in one or more converted non-SBFD symbols.

[0115] According to some examples, the method also includes: receiving or transmitting all occurrences of periodic DL channels or signals that do not overlap with the one or more conversions of the DL channel or signal.

[0116] According to some examples, if the symbol of an SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 2, then the resources of the UL subband in at least one symbol of the SSB are not permitted for DL ​​reception, and the resources of the UL subband in at least one symbol of the SSB are used for UL transmission.

[0117] According to some examples, if the symbol of the SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 2, and at least one of the DL RBG for PDSCH, PDSCH PRG, CSI-RS resource, CORESET, RBG for CORESET, or CSI report subband spans the DL subband and the UL subband, then at least one of the DL resource block group RBG for PDSCH, PDSCH PRG, CSI-RS resource, CORESET, RBG for CORESET, or CSI report subband is invalid.

[0118] According to some examples, if the symbol of the SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 2, and the SSB overlaps with the UL subband or the guard band of the UL subband in the frequency domain, then the resources of the UL subband are permitted for DL ​​reception, and the resources of the UL subband are not permitted for UL transmission.

[0119] According to some examples, the method further includes at least one of the following: conversions generated by resources of the UL subband permitted for DL ​​reception are not counted in the maximum threshold number of conversions between non-SBFD symbols and SBFD symbols, wherein the conversions include conversions from the SBFD symbols to the non-SBFD symbols and conversions from the non-SBFD symbols to the SBFD symbols; resources of the DL conversion block TB are permitted to be located in the UL subband; resource blocks RB of the DL TB are permitted to span the DL subband and the UL subband in the frequency domain; DL A portion of the frequency domain resources of the TB are located in the DL subband, and another portion of the frequency domain resources of the DLTB are located in the UL subband; at least one of the following across the DL subband and the UL subband—the DL resource block group RBG for the Physical Downlink Shared Channel (PDSCH), the PDSCH polarization multiplexing group PRG, the Channel State Information Reference Signal (CSI-RS) resource, the Control Resource Set (CORESET), the resource block group RBG for CORESET, or the CSI report subband—is considered valid; the symbols of the SSB are considered not configured with SBFD subbands; the symbols of the SSB are converted to non-SBFD symbols; and / or one or more PDSCHs are repeatedly received in one or more of the converted non-SBFD symbols.

[0120] According to some examples, if the symbol of an SSB is configured as an SBFD subband with a UL subband, and the SSB is of type 2, and the SSB overlaps with the UL subband or the guard band of the UL subband in the frequency domain, then the resources in the UL subband other than the resources of the SSB are permitted for UL transmission, rather than for DL ​​reception.

[0121] According to some examples, at least one of the following subbands spanning the DL subband and the UL subband is considered invalid: DL resource block group RBG for PDSCH, PDSCH PRG, CSI-RS resource, CORESET, RBG for CORESET, or CSI report subband.

[0122] According to some examples, the period is aligned with the configuration period of the SBFD subband, which is aligned with the half-frame.

[0127] This document describes various exemplary embodiments of the present disclosure with reference to the accompanying drawings to enable those skilled in the art to make and use the disclosure. The disclosure is not limited to the exemplary embodiments and applications described and illustrated herein. Furthermore, the specific order and / or hierarchy of steps in the methods disclosed herein are merely exemplary methods. Based on design preferences, the specific order or hierarchy of steps in the disclosed methods or processes may be rearranged while remaining within the scope of this disclosure. Therefore, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or actions in one or more exemplary orders, and unless otherwise expressly stated, the disclosure is not limited to the specific order or hierarchy presented.

[0128] This disclosure is intended to cover any conceivable variations, uses, combinations, or adaptations of this disclosure that follow the general principles thereof, and includes common knowledge and conventional techniques not disclosed in the art or in this application.

[0129] It should be understood that this disclosure is not limited to the precise structures or operations shown above and in the accompanying drawings, and various modifications and changes can be made without departing from the scope of this application. The scope of this application is limited only to the appended claims.

[0130] The methods, devices, processes, circuits, and logic described above can be implemented in a variety of different ways and with a variety of different hardware and software combinations. For example, all or part of the implementation may be a circuit including an instruction processor or controller (such as a central processing unit (CPU), microcontroller, or microprocessor); or an application-specific integrated circuit (ASIC), programmable logic device (PLD), or field-programmable gate array (FPGA); or a circuit including discrete logic or other circuit components (including analog circuit components, digital circuit components, or both); or any combination thereof. For example, the circuit may include discrete interconnected hardware components, or be combined on a single integrated circuit chip, distributed across multiple integrated circuit chips, or implemented in a multi-chip module (MCM) of multiple integrated circuit chips in a general-purpose package.

[0131] Therefore, the circuit can store or access instructions to be executed, or its functionality can be implemented entirely in hardware. Instructions can be stored in a tangible storage medium other than transient signals, such as flash memory, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM); or stored on magnetic or optical disks, such as optical disc read-only memory (CDROM), hard disk drive (HDD), or other disks or optical discs; or stored in or on another machine-readable medium. A product (such as a computer program product) may include a storage medium and instructions stored in or on that medium, and when executed by circuitry in the device, the instructions can cause the device to perform any of the processes shown above or in the accompanying drawings.

[0132] These implementations can be distributed. For example, the circuit may include multiple different system components, such as multiple processors and memories, and may span multiple distributed processing systems. Parameters, databases, and other data structures may be stored and managed separately, may be merged into a single memory or database, may be organized logically and physically in a variety of different ways, and may be implemented in a variety of different ways. Example implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records), objects, and implicit storage mechanisms. Instructions may form part of a single program (e.g., subroutines or other code segments), may form multiple independent programs, may be distributed across multiple memories and processors, and may be implemented in a variety of different ways. Example implementations include independent programs, as well as shared libraries, such as Dynamic Link Libraries (DLLs), as part of a library. For example, the library may include shared data and one or more shared programs that include instructions that, when executed by the circuit, perform any of the processes shown above or in the accompanying drawings. In some examples, each unit, subunit, and / or module of the system may include a logic component. Each logic component may be hardware or a combination of hardware and software. For example, each logic component may include an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), digital logic circuits, analog circuits, discrete circuits and gate circuits, or any other type of hardware or combination thereof. Alternatively or additionally, each logic component may include memory hardware, such as a portion of memory, for example, including processor or other processor-executable instructions to implement one or more features of the logic component. When any logic component includes a portion of memory, the memory includes processor or other processor-executable instructions, and the logic component may or may not include a processor. In some examples, each logic component may simply be a portion of memory or other physical memory that includes processor or other processor-executable instructions to implement the functionality of the corresponding logic component, without the logic component containing any other hardware. Because each logic component includes at least some hardware, even if the included hardware includes software, each logic component may be interchangeably referred to as a hardware logic component.

[0133] The second action can be considered a "response" to the first action, regardless of whether the second action is directly or indirectly caused by the first action. The second action can occur much later than the first action and still be a response to the first action. Similarly, even if an intervention occurs between the first and second actions, and even if one or more intervention actions directly lead to the execution of the second action, the second action can be said to be a response to the first action. For example, if the first action sets a flag, and a third action initiates the second action when the flag is set, then the second action can be considered a response to the first action.
