Description
WIRELESS COMMUNICATION FOR MULTIPLEX SUBBANDS WITH SSB SYMBOLSTECHNICAL FIELD
[0001] This disclosure is generally related to wireless communication, and more particularly to wireless communications methods for duplex subbands.BACKGROUND
[0002] Wireless communication technologies are pivotal components of the increasingly interconnecting global communication networks. Wireless communications rely on accurately allocated time and frequency resources for transmitting and receiving wireless signals. Frequency division duplex (FDD) and time division duplex (TDD) allows a better usage of the wireless communication resource. In FDD mode, the frequency domain resource is divided for downlink and uplink. With continuous time domain resources, FDD is characterized by lower latency, lower throughput and scattered spectrum bands. In TDD mode, the time domain resource is split between downlink and uplink, which leads to higher latency. The fixed allocation of time / frequency resources of TDD / FDD has both advantages and limitations.SUMMARY

[0023] Although FD is a new technology to improve spectrum efficiency, simultaneous transmission on downlink (DL) and uplink (UL) will bring severe interference that may lead to design complexity of gNBs (base station, or BS) and user equipment (UE) and increase the costs. Therefore, in the early stage of 5G-Advacned, the focus will be on subband full duplex (SBFD) , and then gradually extended to FD networks applicable to gNBs and UEs.
[0024] Synchronization Signal / PBCH block (SSB) includes of PSS (Primary Synchronization Signal) , SSS (Secondary Synchronization Signal) and Physical Broadcast Channel (PBCH) . According to some embodiments, SSBs can be differentiated into two types: a first type and a second type. For example, if an SBFD subband (such as a subband including a UL subband and a DL subband) is configured in the symbol of the first type SSB, the UL subband in the symbol of the first type SSB may be prohibited from being used for UL transmission. If the SBFD subband is configured in the symbol of the second type SSB alternatively, the UL subband in the symbol of the second type SSB can still be allowed for UL transmission. It is noted that “first” and “second” is just an examplary naming, which does not limit the scope of this invention. With respect to the repetitions of the transmission, PUSCH can also be categorized as type A and type B. For PUSCH type A with k repetitions, each repetition needs to be transmitted in one slot. For example, a PUSCH type A is configured to use 2 symbols and is configured to perform 4 repetitions, with the first repetition transmitted in symbol #0 and symbol #1 in the valid slot n. Assuming slot n+1, slot n+2, and slot n+3 are all valid slots for the type A PUSCH, then the second repetition is transmitted in symbol #0 and symbol #1 in slot n+1, the third repetition is transmitted in symbol #0 and symbol #1 in slot n+2, and the fourth repetition is transmitted in symbol #0 and symbol #1 in slot n+3.
[0025] For a PUSCH type B with k repetitions, the valid symbols need to be determined according to some conditions. Each repetition of the PUSCH type B may be continuously transmitted within the identified valid symbols. The valid symbols are determined in one or more slots. For example, a PUSCH type B is configured to use 2 symbols and is configured to perform 4 repetitions, with the first repetition transmitted in symbol #0 and symbols #1 in slot n. Assuming that symbol #0 to symbol #13 in slot n are both valid symbols for the PUSCH type B, the second repetition is transmitted in symbol #2 and symbol #3 in slot n, the third repetition is transmitted in symbol #4 and symbol #5 in slot n, and the fourth repetition is transmitted in symbol #6 and symbol #7 in slot n.
[0026] Configuration Regarding SSBs of a First Type or of a Second Type
[0027] Example 1. According to some embodiments of this disclosure, a first parameter can be transmitted by a BS to a UE to indicates which SSBs is first type SSB (s) within a half frame duration (or SBFD configuration period) . For example, the first parameter can use bitmap signaling. The number of bits of the first parameter corresponds to the number of the SSBs configured within a half frame duration. The number of bits for the first parameter can be equal to the number of the SSBs configured within a 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, and each bit of the first parameter can be alternatively 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, and each bit of the first parameter can be set to “1” to indicate that the corresponding SSB is not a first type SSB.
[0028] Within a half frame duration, a number of configured SSBs may be 4, 8, or 64 for different cases. 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 a BS to a UE or vice versa. Accordingly, when a UE receives the first parameter that is configured by a BS, the UE can determine the occurrence of a first type SSB and a second type SSB.
[0029] Example 2. Alternatively or additionally, two parameters can be added. For the ease of explanation, the two parameters can be called second parameter and third parameter here. As an example, the second parameter can be added to indicate the grouping of SSBs within the duration of an SSB burst with respect to the occurrence of first type SSBs or second type SSBs within a group. Likewise, the second parameter can use bitmap signaling. The number of bits for the bitmap signaling can be 8 bits, for example.
[0030] In some examples, SSBs can be grouped including according to the following manners. If the number of configured SSBs is 64 in a half frame. An index can be denoted as index 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 to divided the 64 SSBs into 8 groups. These 8 groups correspond to the bitmap signaling respectively of the paramenter. If the number of SSBs within a half frame duration is 4 or 8, the second parameter is not necessarily, according to some examples.
[0031] For example, the second parameter can carry a first value, like “1” , or a second value, like “0. ” The first value in the bitmap signaling indicates that at least one of SSBs in the corresponding group is a first type SSB, while the second value indicates that none of the SSBs in the corresponding group is a first type SSBs.
[0032] Additionally, a third parameter can be added to indicate which SSB (s) is a first type SSB (or alternatively a second type SSB) in a corresponding SSB group, for which of the second parameter indicating the occurrence of at least one first type 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 with the number of bits in an SSB group. As an example, a first value (e.g., “1” ) in the bitmap signaling can indicate that the corresponding SSB is a first type SSB (or alternatively not a first type SSB) , while a second value (e.g., “0” ) can indicates that the corresponding SSB is not a first type SSB (or alternative is a first type SSB) .
[0033] For example, the first and second groups of a half frame can have first type SSB (s) according to the indication of the second parameter. Correspondingly, the second parameter can have signaling of “11000000. ” In addition, the third parameter may indicate that the first type SSB and the third SSB within each selected group. Correspondingly, the third parameter can be 10100000. Therefore, the final indexes of the first type SSB can be index 0, index 2, index 8, and index 10.
[0034] As an example, if the number of configured SSBs is 8 within a half frame, the second parameter is not necessarily. In this case, each bitmap of the third parameter may correspond to one SSB in each group. If the number of configured SSBs is 4 within half a frame, the second parameter is not required either. In this case, the lower 4 bits of the third parameter can be used, and the higher 4 bits can be omitted. As an example, A value of 1 in the bitmap signaling indicates that the corresponding SSB is a first type SSB, while a value of 0 indicates that the corresponding SSB is not a first type SSB.
[0035] The parameters can be transmitted from a BS to a UE or vice versa. Accordingly, when a UE receives the first parameter that is configured by the BS, the UE can determine the occurrence of a first type SSB and a second type SSB. The parameters can be used to determine a first type SSB, and the parameters can also be used to determine a second type SSB, depending on whether the BS and UE’s understanding on which type of the SSB to be identified.
[0036] Example 3. Additionally or alternatively, a BS and UE may agree that the configuration of an SBFD subband (including UL and DL subbands) can be on a transmission cycle. The size and starting point of the cycle can be aligned with a duration and starting point of a half frame. Alternatively or additionally, if a period of a frame is a combination of two short sub-frames, and DL slot and UL slot configurations within the two short frames are the same or different, a SBFD subband configuration can be based on the period of the frame; a size and starting point of the cycle for the SBFD subband can be aligned with the period and start of the frame.
[0037] In this case additionally, a fourth parameter (alternatively or additionally) can be added to indicate which SSB (s) is a first type SSB (or alternatively a second type SSB) among all SSBs included in the configured cycle of the SBFD subband. As an example, the fourth parameter can use bitmap signaling, and the number of bits in this bitmap signaling can corresponds to or be equal to the number of SSBs included in a configuration cycle of a SBFD subband. In the bitmap signaling for example, a first value ( “1” as an example) may indicate that the corresponding SSB is a first type SSB; a second value (exemplarily “0” ) may indicate that the corresponding SSB is not the first type SSB. The parameter can be used to determine the first type SSB, and the parameter can also be used to determine the second type SSB, depending on whether the BS and UE’s understanding on which type of the SSBs to be identified.
[0038] Accordingly, the configuration period of the SBFD subband and the SSB can be both aligned with half frames, which is conducive to including the same number and position of SSBs in each SBFD cycle and is conducive for the arrangement of the fourth parameter.
[0039] Example 4. Additionally or alternatively, a fifth parameter can be introduced to replace the fourth parameter to reduce signaling overhead. The fifth parameter can be used to indicates which SSB (s) in the configuration cycle are a first type SSB (or alternatively or additionally a second type SSB) for those SSBs overlapping with a UL subband (in a DL slot) or for those SSBs having SBFD symbols. The fifth parameter can be a bitmap signaling, and the number of bits in the bitmap signaling can correspond or be equal to the number of those SSB overlapping with a UL subband or with SBFD symbols within the configuration cycle of an SBFD subband. In the bitmap signaling for example, a first value (e.g., “1” ) can indicate that the corresponding SSB is a first type SSB; a second value (e.g., “0” ) can indicate that the corresponding SSB is not the first type SSB (or is the second type SSB) . Referring to Fig. 1 as an example, the configuration period of an SBFD subband is aligned with a half frame. According to Example 4, the bitmap signaling of the fifth parameter has 3 bits because there are three SSBs at the second and there to the right and second and third from the left slots, where the SSBs overlap with a UL subband (and in a DL slot) or is of SBFD symbols. On the other hand, according to Example 3, the bitmap signaling of the fourth parameter is 4 bits to indicate the four SSBs as shown in Fig. 1.
[0040] In Examples 1 to 4, the SSBs can be defined as a CD-SSB (Center-Dot SSB) and / or NCD-SSB. That is to say, the parameters above may further indicate which SSBs are a first type SSB from CD-SSBs, may further indicate which SSBs are a first type SSB from NCD-SSBs, or further may indicate which SSBs are a first type SSB from CD-SSBs and NCD-SSBs.
[0041] The parameters above can be transmitted from a BS to a UE or vice versa. Accordingly, when a UE receives the parameter that is configured by the BS, the UE can determine the occurrence of a first type SSB and / or a second type SSB. The parameters can be used to determine a first type SSB, and the parameters can also be used to determine a second type SSB, depending on whether the BS and UE’s understanding on which type of the SSB to be identified.
[0042] Example 5. According to some embodiments, if the symbol of SSB is configured with a SBFD subband (including the UL subband and DL subband) , and if a UL transmission is scheduled or configured in the resources of the UL subband, the UL transmission can be executed according to at least one of the following examples.
[0043] First, a BS can indicate whether a UE can perform the UL transmission in the UL subband of the SSB symbols through an RRC (Radio Resource Control) signaling or a DCI (Downlink Control Index) signaling.
[0044] Example 5-1: A Parameter A can be added to the DCI (Downlink Control Information) , which can be transferred from the BS to the UE. Parameter A may indicate whether a UL transmission is or can be executed in the UL subband. If a UL transmission is scheduled in the UL subband, the UE can determine whether the UL transmission is executed based on parameter A in the DCI. That is, the UE can receive the DCI with the Parameter A and use the DCI to determine if the DL reception is executed or scheduled by the BS according the indication of the Parameter A in the DCI.
[0045] Example 5-2: Additionally or alternatively, for a UE that has the ability to perform UL transmission in the UL subband of the SSB symbols, the BS can configure whether the UE performs UL transmission in the UL subband of the SSB symbols through an RRC (Radio Resource Control) signaling or DCI signaling. For example, assuming that a UE is configured to perform a UL transmission in the UL subband through the RRC signaling, and if a UL transmission is scheduled in the UL subband through the DCI (which may or may not include the above Parameter A) , the UE can perform the UL transmission. Assuming that the UE is not configured to perform a UL transmission in the UL subband through the RRC signaling, if a UL transmission is scheduled in the UL subband through the DCI (which does not include the above parameter A) , the UE does not perform the UL transmission. That is, the BS can use a signaling, such as RRC or DCI signaling, to configured the UE. Once the UE receives the signaling, the UE can determine according to the signaling that whether the UL transmission is configured by the BS at the UL subband in a DL slot.
[0046] Example 5-3: Additionally or alternatively, an RRC signaling can be introduced. The BS can notify the UE through the RRC signaling to determine whether to perform UL transmission in the UL subband based on Parameter A in a DCI. If a UL transmission is scheduled by a DCI in the UL subband, and parameter A is included in the DCI, the UE determines whether to execute the UL transmission based on the indication of parameter A.
[0047] Example 5-4: Additionally or alternatively, an RRC signaling that includes two indication state can be introduced. The first (or the second) indicator status may indicates that UE does not perform a UL transmission if the UL transmission is configured or scheduled in the UL subband. The second (or the first) indicator status can indicate whether the UE performs a UL transmission based on parameter A in a DCI if the UL transmission is scheduled in the UL subband. If the first indicator status is configured by a BS for a UE, the UE always does not perform a UL transmission if the UL transmission is scheduled in the UL subband. If the second indicator status is configured by a BS for a UE, the UE determines whether a UL transmission is executed based on parameter A in DCI if the UL transmission is configured or scheduled in the UL subband. For example, the BS may send an signaling having two states. The UE may receive the signaling and use the signaling to determine whether the UL transmission is disabled or enabled. The first status may disable the UE’s UL transmission even if the UL transmission is scheduled by the BS, and the second status allows the UE to perform UL transmission based on Parameter A if the UL transmission is configured or scheduled by the BS in the UL subband.
[0048] Example 5-5: Additionally or alternatively, a BS and UE may agree that if a high-priority UL transmission is scheduled by DCI in a resource in a UL subband of a DL slot, the UE can consider the resource to be valid. The UE performs the UL transmission, and the BS believes that the UE performs the UL transmission. The UE therefore determines whether to perform a UL transmission based on whether there is a high priority UL transmission scheduled by the BS.
[0049] Example 5-6: Additionally or alternatively, a BS and a UE may agree that if a high priority semi-static UL transmission is configured in a resource in a UL subband of a DL slot, the UE can consider the resource to be valid, but whether the UE performs the UL transmission is based on the UE’s requirements, and the base station considers the resource to be valid.
[0050] Example 5-7: Additionally or alternatively, a BS and UE agree that if a low-priority UL transmission is scheduled by a DCI in a resource in a UL subband of a DL slot, the UE can consider the resource to be invalid, and the UE does not perform the UL transmission. The BS believes that the UE does not perform the UL transmission. The BS prohibits scheduling this UL transmission, and UE does not expect to be scheduled for this UL transmission.
[0051] Example 5-8: Additionally or alternatively, a BS and UE can agree that if a low-priority UL transmission is scheduled by a DCI in a resource in a UL subband of a DL slot, the UE can consider the resource to be valid, but the UE does not perform the UL transmission, and the BS understood that the UE does not perform the UL transmission. The BS may prohibit scheduling this UL transmission, and UE does not expect to be scheduled for this UL transmission.
[0052] Example 5-9: Additionally or alternatively, a BS and UE can agree that if a low priority semi static UL transmission is configured in a resource in the UL subband, the UE can consider the resource to be invalid, and the UE does not perform the UL transmission. The BS understood that the UE does not perform the UL transmission. The BS may prohibit scheduling this UL transmission, and UE does not expect to be scheduled for this UL transmission.
[0053] Example 5-10: Additionally or alternatively, a BS and a UE can agree that if a low priority semi-static UL transmission is configured in a resource in the UL subband, the UE can consider the resource to be valid, but the UE does not perform the UL transmission. The BS believes that the UE does not perform the UL transmission. The BS may prohibit scheduling this UL transmission, and UE does not expect to be scheduled for this UL transmission. In some examples above, the UE can determine whether a resource in the UL subband is valid or not or determine whether the UL transmission can be performed based on whether the scheduled UL transmission is high or low priority and whether it is semi static or not. The BS agrees with the UE about the determination flow and understand the UE’s determination.
[0054] In Example 5, additionally or alternatively, a BS and a UE can agree that, if the UL transmission is not executed based on the above Examples 5-1~5-10 or their combinations, but the corresponding resource of the UL transmission is considered valid, the resource can be counted toward to a number of valid resources. Alternatively, the BS and UE can agree that if the UL transmission is not executed according to above Examples 5-1~5-10 or their combinations, the resource corresponding to the UL transmission is not counted as toward a number of valid resources.
[0055] Example 6. The Repetitions of Transmission
[0056] This section of this disclosure discuss, additionally or alternatively to the other examples, the scheduling of receptions of transmission when the frame is scheduled in first type or second type SSB (s) in SBFD subbands. For example, the repetitive transmission includes PUSCH transmission corresponding to a TB. One transmission of a TB (Transmission Block) is in a time slot among N slots, and the TB is repeatedly transmitted k times. Here, N can be an integer and greater than or equal to 1. For example, if a TB corresponding to a PUSCH needs one slot for transmission, the k repetitions of the PUSCH require k slots. If the TB corresponding to a PUSCH needs 2 slots for transmission, the k repetitions corresponding to the PUSCH require 2 *k slots.
[0057] Example 6-1. Alternatively or additionally, a BS and a UE can agree that, for a PUSCH type A with k repetitions, if the UE is configured to determine N *k slots via an RRC message, N *k slots can be determined based on UL subband configuration, SSB type, and / or the symbols of the PUSCH.
[0058] Example 6-1-1: Alternatively or additionally as an example, for a PUSCH type A with k repetitions, if a SBFD subband (including the UL subband and / or DL subband) is configured in the symbols of a first type SSB in a time slot (such as a DL slot) , and at least one symbol of the PUSCH overlaps with the symbols of the first type SSB in the time domain, the slot is not counted in N *k slots. That is, N *k slots do not include a slot that meets the above condition. Otherwise, a slot that does not meet such condition can be counted in N *k slots. That is, the PUSCH is not allowed to be transmitted in a slot where a SBFD subband is configured in the symbols of a first type SSB in such slot. and at least one symbol of the PUSCH (if so configured) overlaps with the symbols of the first type SSB in the time domain.
[0059] Additionally or alternatively, the frequency domain resources of the PUSCH can be configured based on the UL subband; the frequency domain resources of the PUSCH can be within the UL subband.
[0060] Example 6-1-2: Additionally or alternatively as an example, for a PUSCH type A with k repetitions, if a SBFD subband (including the UL subband and / or DL subband) is configured in the symbols of a first type SSB in a slot, and at least one symbol of the PUSCH overlaps with the symbols of the first type SSB in the time domain, the slot is counted in N *k slots. That is, the N *k slots include the such slot that meets the condition above. That is, the PUSCH is not allowed to be transmitted in a slot where if a SBFD subband (including a UL subband and / or DL subband) is configured in the symbols of a first type SSB in such slot, and at least one symbol of the PUSCH overlaps with the symbols of the first type SSB in the time domain. However, whether the PUSCH is ultimately transmitted still needs to consider 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 within the UL subband. Otherwise, a slot that does not meet such condition cannot be counted in N *k slots.
[0061] Example 6-1-3: Additionally or alternatively as an example, for a PUSCH type A with k repetitions, if in a slot, at least one symbol of the PUSCH overlaps in time domain with the symbol of the first type SSB or the DL symbol of the unconfigured the SBFD subband, the slot is not counted in the N*k slots. That is, the N*k slots do not include the slot. Otherwise, a slot that does not meet the above condition can be counted toward the N*k slots. That is, the PUSCH is not allowed to be transmitted in a slot where at least one symbol of the PUSCH overlaps in time domain with the symbol of the first type SSB or the DL symbol of the unconfigured the SBFD subband. The PUSCH can be scheduled by DCI or configured for RRC signaling. The DL symbol can be configured through tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. Additionally, the symbols of the first type SSB can be configured with the SBFD subband. The first type SSB is a part of the SBFD subband. Additionally, the frequency domain resources of the PUSCH can be configured based on the UL subband; that is, the frequency domain resources of the PUSCH can be within the UL subband.
[0062] Example 6-1-4: Additionally or alternatively as an example, for a PUSCH type A with k repetitions, if in a candidate slot, at least one symbol of the PUSCH overlaps with the symbol of the SSB in the time domain, at least one of the following configurations can be set up, for example, based on the BS’s signaling:
[0063] (1) If the symbol of the SSB is not configured with the SBFD subband (assuming that the SSB is not classified as a first type SSB and a second type SSB) , the candidate slot is not counted toward the N*k slots; that is, the N*k slots do not include the candidate slot. That is, the PUSCH is not allowed to be transmitted in a candidate slot where at least one symbol of the PUSCH overlaps with the symbol of the SSB in the time domain and the symbol of the SSB is not configured with the SBFD subband; and / or
[0064] (2) If the symbol of the SSB is configured with the SBFD subband (assuming that the SSB is not classified as a first type SSB and a second type SSB) , the candidate slot is counted toward the N*k slots; that is, the N*k slots include the slot. That is, the PUSCH is allowed to be transmitted in a candidate slot where at least one symbol of the PUSCH overlaps with the symbol of the SSB in the time domain and the symbol of the SSB is configured with the SBFD subband; and / or
[0065] (3) If the symbol of the SSB is configured with the SBFD subband and the SSB is a first type SSB, the candidate slot is not counted toward the N*k slots. That is, the N*k slots do not include the candidate slot. The PUSCH is not allowed to be transmitted in a candidate slot where at least one symbol of the PUSCH overlaps with the symbol of the SSB in the time domain and the symbol of the SSB is configured with the SBFD subband and the SSB is the first type SSB; and / or
[0066] (4) If the symbol of the SSB is configured with the SBFD subband and the SSB is a second type SSB, the candidate slot is counted toward the N*k slots; that is, the N*k slots include the candidate slot. That is, the PUSCH is allowed to be transmitted in a candidate slot where at least one symbol of the PUSCH overlaps with the symbol of the SSB in the time domain and the symbol of the SSB is configured with the SBFD subband and the SSB is the second type SSB.
[0067] The frequency domain resources of the PUSCH can be configured based on the UL subband; that is, the frequency domain resources of the PUSCH can be within the UL subband.
[0068] Example 6-1-5: Additionally or alternatively as an example, for a PUSCH type A with k repetitions, if in a candidate slot, at least one symbol of the PUSCH overlaps with a UL symbol, a F symbol, a DL symbol of the configured the SBFD subband, or a symbol of a second type SSB of the configured the SBFD subband, the candidate slot is counted toward the N*k slots; that is, the N*k slots include the candidate slot. That is, a PUSCH is allowed to be transmitted in the candidate slot where at least one symbol of the PUSCH overlaps with a UL symbol, a F symbol, a DL symbol of the configured the SBFD subband, or a symbol of the second type SSB of the configured the SBFD subband. However, whether a PUSCH is ultimately transmitted still needs to consider other conditions.
[0069] In addition, the PUSCH can be scheduled by DCI or configured for RRC signaling. The UL symbol, the F symbol, or the DL symbol can be configured through tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. In addition, the symbols of a first type SSB are configured with the SBFD subband. The first type SSB can be a part of the SSB. The frequency domain resources of the PUSCH can be configured based on the UL subband; that is, the frequency domain resources of the PUSCH can be within the UL subband.
[0070] Example 6-2. Additionally or alternatively as an example, a BS and a UE may agree that for a PUSCH type A with k repetitions, if the UE is configured to determine N *k slots via an RRC message, then N *k slots can be determined based on UL subband configuration and the symbols of the PUSCH.
[0071] For example, for a PUSCH type A with k repetitions, if in a candidate slot, at least one symbol of the PUSCH overlaps with a DL symbol in the time domain, at least one of the following configurations can be set up, for example, based on the BS’s signaling:
[0072] (1) If the DL symbol is not configured with a SBFD subband, the candidate slot is not counted toward the N*k slots; that is, the N*k slots do not include the candidate slot. That is, a PUSCH is not allowed to be transmitted in a candidate slot where at least one symbol of the PUSCH overlaps with a DL symbol in the time domain and the DL symbol is not configured with a SBFD subband; and / or
[0073] (2) If the DL symbol is configured with a SBFD subband, the candidate slot is counted toward the N*k slots; that is, the N*k slots include the slot. That is, a PUSCH is allowed to be transmitted in a candidate slot where at least one symbol of the PUSCH overlaps with a DL symbol in the time domain and the DL symbol is not configured with a SBFD subband.
[0074] Here, the frequency domain resources of the PUSCH can be configured based on the UL subband; that is, the frequency domain resources of the PUSCH can be within the UL subband.
[0075] For the examples above, if a UE or a BS agree that a certain slot is not counted toward the N*k slots, the BS may avoid scheduling a PUSCH repartition in such slot, and the UE expects that in such slot there would be no PUSCH repartition schedule in such slot.
[0076] Example 7. Resources for UL Transmission
[0077] Regarding 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 a SBFD subband (including a UL subband and a DL subband) , a UL transmission can be performed according to at least one of the following conditions, especially if the UL transmission is a configured semi-static UL transmission.
[0078] Example 7-1: The BS and UE may agree that for a scheduled or configured UL transmission (including repetitions) , if at least one symbol of the UL transmission overlaps with a symbol of the first type SSB in the time domain, the UL transmission is not executed by the UE. Here, regardless of whether the symbol of the first type SSB is configured as the SBFD subband.
[0079] Example 7-2: Alternatively or additionally, a BS and a UE can agree that for a scheduled or configured UL transmission (including a repetitions) , if at least one symbol of the UL transmission overlaps with a symbol of the second type of SSB in the time domain, the UL transmission is allowed to be transmitted. Here, the symbol of the second type SSB is configured as the SBFD subband.
[0080] Example 7-3: Alternatively or additionally, a BS and UE can agree that for a scheduled or configured UL transmission (with or without repetitions) , if a starting symbol of the UL transmission is after the end of the SSB and there is a gap as shown in Fig. 2A, at least one of the following configurations can be set up, for example, based on the BS’s signaling:
[0081] (1) Alternatively or additionally, if the SSB is determined to be the a first type SSB, and the symbols of the SSB are configured with a SBFD subband, and the gap is greater than or equal to a gap threshold, a BS considers that the UL transmission is allowed, and the UE is allowed to perform the UL transmission. That is to say, the resources of the UL transmission are valid;
[0082] (2) Alternatively or additionally, if the SSB is determined to be a first type SSB and the symbols of the SSB are configured with a SBFD subband, and the gap is less than a gap threshold, a BS considers that the UL transmission is not allowed, and the UE is not allowed to perform the UL transmission. That is to say, the resources of the UL transmission are invalid; and / or
[0083] (3) Alternatively or additionally, if the SSB is determined to be a second type SSB and the symbols of the SSB are configured with a SBFD subband, a BS considers that the UL transmission is allowed and the UE is allowed to perform the UL transmission. The gap size does not need to be considered. That is to say, the resources of the UL transmission are valid, whether or not the gap exists.
[0084] Example 7-4: Alternatively or additionally, a BS and a UE may agree that for a scheduled or configured UL transmission (with or without repetition) , if the end symbol of the UL transmission precedes the start symbol of the SSB and there is a gap as shown Fig. 2B, at least one of the following configurations can be set up, for example, based on the BS’s signaling:
[0085] (1) Alternatively or additionally, if the SSB is determined to be a first type SSB, and the symbols of the SSB are configured with a SBFD subband, and the gap is greater than or equal to a gap threshold, a BS considers that the UL transmission is allowed and a UE is allowed to perform the UL transmission. That is to say, the resources of the UL transmission are valid.
[0086] (2) Alternatively or additionally, if the SSB is determined to be a first type SSB, and the symbols of the SSB are configured with a SBFD subband, and the gap is less than a gap threshold, a BS considers that the UL transmission is not allowed and a UE is not allowed to perform the UL transmission. That is to say, the resources of the UL transmission are invalid.
[0087] (3) Alternatively or additionally, if the SSB is determined to be a second type SSB and the symbols of the SSB are configured with a SBFD subband, a BS considers that the UL transmission is allowed and a UE is allowed to perform the UL transmission. The gap does not need to exist for the BS and the UE to agree that the UL transmission is permissible. That is to say, the resources of the UL transmission are valid.
[0088] Alternatively or additionally, the above gap threshold in different examples can be related to a subcarrier spacing (SCS) . For example, when the SCS is less than or equal to 120Khz, the gap threshold may correspond to 2 symbols. When the SCS is equal to 480KHz, the gap threshold may correspond to 8 symbols. When the SCS equals to 960KHz, the gap threshold may correspond to 16 symbols. Alternatively or additionally, the UL transmission mentioned above includes semi-static PUSCH / PUCCH / SRS and dynamically scheduled PUSCH / PUCCH / SRS.
[0089] In the examples above, the BS may use a configuration signaling to set up the specific configuration of the UE to establish on or more rules for the determination of the validity of a UL transmission resource. Based on the configuration of the configuration signaling, the UE may form an agreement with the BS to understand whether the UL transmission is permissible in respective UL subband.
[0090] Example 8: Transmission of Type B PUSCH Repetition
[0091] For a first type SSB or a second type SSB determined according to Examples 1 to 4, if the symbol of the SSB is configured with the SBFD subband (including the UL subband and the DL subband) , valid symbols for PUSCH type B with k repetitions can be determined according to the at least one of the following conditions. For example, a BS a UE can agree that for a type B PUSCH with k repetitions, the valid symbols of the PUSCH can be determined based on the SBFD subband configuration and / or SSB type.
[0092] For example, for a type B PUSCH resource with k repetitions, if the PUSCH resource includes symbols of the SSB configured with a SBFD subband, the BS and UE agree that the valid symbol for the PUSCH is determined according to the following conditions:
[0093] (1) If the SSB is determined to be a first type SSB, the symbols of the first type SSB configured with a SBFD subband are invalid for a type B PUSCH; or
[0094] (2) Additionally or alternatively, if the SSB is determined to be a second type SSB, the symbols of the SSB configured with a SBFD subband are valid for a type B PUSCH.
[0095] As an example, for a type B PUSCH resource with k repetitions, if the PUSCH resource includes a DL symbol, a BS and a UE can agree that the valid symbol for the PUSCH is determined according to at least one of the following conditions:
[0096] (1) If the DL symbol is configured with a SBFD subband, the DL symbol is valid for the type B PUSCH; or
[0097] (2) If the DL symbol is not configured with a SBFD subband, the DL symbol is type B invalid for the PUSCH.
[0098] As explained above, the configuration of UE can be set up by, for example, a signaling of the BS, such that the BS and the UE can form an agreement on the action and the treatment of the conditions explain above. Thereby, the UE and the BS may be able to understand the action and the decision that would be taken by the other end.
[0099] Example 9: Use of UL Subband of SBFD Subband
[0100] This section discusses issues including how to use a UL subband of a SBFD Subband in different conditions. According to some examples, the following rule has been established regarding a maximum number of transition points between SBFD symbols to non-SBFD symbols.
[0101] For a first type SSB or a second type SSB determined according to Examples 1 to 4, if symbols of the SSB is configured with a SBFD subband (including a UL subband and a DL subband) , the resources of the UL subband in the SSB symbols can be used based on at least one of the following Examples. The discussion of the use of a SBFD subband can be discussed in the following two circumstances.
[0102] Example 9-1. This disclosure first discusses the situation when a first or second type SSB does not overlap with a UL subband as shown in Fig. 3. The frequency domain resources of the SSB configured by a BS do not overlap with the frequency domain of the UL subband in the frequency domain as shown Fig. 3. In this case, the frequency domain resources of the SSB can be in a DL subband and / or in a gap of the frequency domain, but not in the frequency domain resources of the UL subband. Under Example 9-1, if a SSB is determined to be a first type SSB, then the resources of the UL subband in the first type SSB symbols are not allowed to be used for UL transmission, and the resources of the UL subband in the first type SSB symbols are allowed to be used for DL reception / transmission. In order to further improve the efficiency of the UL subband resources, at least one of the following Examples can be configured between BS and UE and adopted for wireless transmission:
[0103] Example 9-1-1. Additionally or alternatively, a BS and a UE can agree that if a SSB is determined to be a first type SSB, then DL reception is allowed in the resources in the UL subband (or frequency domain gap between UL subband and DL subband) in the first type SSB symbol. The transition points caused by the DL reception (including the transitions from SBFD symbol to non-SBFD symbol and from non-SBFD symbol to SBFD symbol) are not counted toward the agreed maximum number of transition points.
[0104] Example 9-1-2. Additionally or alternatively, a BS and a UE can agree that if a SSB is determined to be a first type SSB, then the DL transport block (TB) corresponding to a DL reception is allowed to use the resources in the UL subband of the first type SSB symbols. Specifically, the resources for the DL TB can be in resources of the UL subband; additionally or alternatively, the RBs for the DL TB can span over the DL subband and the UL subband in the frequency domain; additionally or alternatively, a portion of frequency domain resources for the DL TB can be in the DL subband and the other portion can be in the UL subband.
[0105] Example 9-1-3. Additionally or alternatively, a BS and UE agree that if the SSB is determined to be the first type SSB, and if a DL RBG (Resource Block Group) for PDSCH (or PRG of PDSCH, or a CSI-RS resource, or CORESET, or RBG for CORESET, or CSI reporting subband) spans over the DL subband and the UL subband in the frequency domain, the DL RBG for PDSCH (or the PRG of PDSCH, or the CSI-RS resource, or the CORESET, or the RBG for CORESET, or the CSI reporting subband) is valid. That is, some resources of the DL RBG (or the PRG, or the CSI-RS, or the CORESET, or the RBG, or the CSI reporting subband) in the UL subband are valid.
[0106] Example 9-1-4. Additionally or alternatively, a BS and UE agree that if a SSB is determined to be a first type SSB and the symbols of the SSB are configured with a SBFD subband, the symbols of the SSB are considered as SSB symbols not configured with a SBFD subband; that is, the SSB symbols configured with the SBFD subband are converted to SSB symbols not configured with a SBFD subband for DL reception.
[0107] Example 9-1-4-1. Currently, a DL reception or UL transmission may be prohibited from crossing a SBFD symbol and a non-SBFD symbol in one slot in order to simplify UE complexity. Assuming that a PDSCH corresponds to symbols 5-13, where the symbols of the first type SSB are symbols 5-8, and the symbols of the first type SSB are configured with the SBFD subband, while symbols 9-13 are not configured with the SBFD subband. The PDSCH cannot be transmitted based on the current setting because it spans over both SBFD symbols and non-SBFD symbols in the one slot. In order to fully utilize the resources in a UL subband of a first type SSB symbols, at least one of the following rules or configurations (or their combination) can be set up between a BS and a UE.
[0108] Additionally or alternatively according to this example, assuming DL reception is configured or scheduled in a slot, and the symbols of the DL reception include SSB symbols, and the SSB symbols are configured with the SBFD subband. If the SSB is determined to be the first type SSB, then the SSB symbols can be converted to non-SBFD symbols to execute DL reception. Accordingly, the symbols 5-8 of the first type SSB in the above example are converted to non-SBFD symbols. Accordingly, symbols 5-13 of the PDSCH are considered as non-SBFD symbols, so the DL reception corresponding to the PDSCH can be executed in the slot.
[0109] As shown in Figs. 4A and 4B. A DL channel or signal can be transmitted across non-SBFD symbols and SBFD symbols. Since the SBFD symbols are the symbols of a first type SSB, the symbols of the first type SSB configured with the SBFD subband is converted to non- SBFD symbols. The symbols of the first type SSB configured with the SBFD subband is considered as a non-SBFD symbols
[0110] Example 9-1-4-2. According to a current setting, the following conclusions have been reached. For DL receptions across SBFD symbols and non-SBFD symbols in different slots (each DL reception within a slot has both all SBFD or all non-SBFD symbols) , two Options are provided as follows. The non-SBFD symbol refers to symbol that is not configured with the SBFD subband.
[0111] Additionally or alternatively according to this example, if a SSB is determined to be a first type SSB and if for a DL repetition across SBFD symbols and non-SBFD symbols in different slots, a BS and a UE agree that the symbols of a first type SSB configured with a SBFD subband are converted to non-SBFD symbols to execute the DL repetitions based on the above Options 1 or 2. The DL repetitions includes at least one of: PDSCH repetitions, SPS PDSCH, Multi-PDSCH scheduled by a single DCI, Periodic / semi-persistent CSI-RS, PDCCH, or DL DMRS.
[0112] Additionally or alternatively according to this example, if a PDSCH with k repetitions is configured or scheduled, and the PDSCH is executed based on the above Option 1 or Option 2, and a SSB symbols are configured with a SBFD subband, a BS and a UE can agree that if the SSB is determined to be a first type SSB, symbols of the first type SSB configured with the SBFD subband are converted to non-SBFD symbols in order to transmit different repetitions of the PDSCH based on Option 1 or Option 2.
[0113] For example, based on Option 1, if the first n (n is greater than or equal to 1) repetitions of the PDSCH are all in non-SBFD symbols, the remaining repetitions of the PDSCH can use the first type SSB symbols of the configured the SBFD subband because the first type SSB symbols are converted to the non-SBFD symbols. Figs. 5A and 5B and Figs. 6A and 6B provide exemplary illustrations, where the frequency domain resources of the DL channel or signal are not within the UL subband in Figs. 5A and 5B, but the frequency domain resources of the downlink channel or signal are within the UL subband in Figs. 6A and 6B. In Figs. 5A and 6A, according to Option 1, because at least one of the DL channels or signals is not in SBFD symbols, the rest of the DL channels or signals cannot use the SBFD symbols with SSB symbols at the fifth slot from the left. In Figs. 5B and 6B, according to Option 1 with the above mentioned improvement, because the first type SSB symbols are converted to the non-SBFD symbols, the third DL channel or signal can be allocated at the fifth slot from the left. The resource can be use more efficiently.
[0114] Additionally or alternatively based on Option 1, if first n repetitions of the PDSCH are all in SBFD symbols, the remaining repetitions of the 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. An example is shown in Figs. 7A and 7B. In Fig. 7A, the first type SSB symbols are not converted to the non-SBFD symbol, so the third DL signal or channel can still be allocated at the fifth slot from the left. In Fig. 7B, because the first type SSB symbols are converted to the non-SBFD symbol at the fifth slot, the third DL signal or channel need to skip the fifth slot from the left.
[0115] Additionally or alternatively, assuming multiple PDSCHs are scheduled by DCI, the multiple PDSCHs are executed based on the above Option 1 or Option 2, and the SSB symbols are configured with the SBFD subband, a BS and a UE can agree that if a SSB is determined to be a first type SSB, the symbols of the first type SSB configured with the SBFD subband are converted to non-SBFD symbols in order to transmit different PDSCH of the multiple PDSCHs based on Option 1 or Option 2.
[0116] For example, based on Option 1, if the first n (n is greater than or equal to 1) PDSCHs of the multiple PDSCHs are all in the non-SBFD symbols, the remaining PDSCHs of the multiple PDSCHs can use the first type SSB symbols of the configured the SBFD subband because the first type SSB symbols have been converted to the non-SBFD symbols.
[0117] For example, based on Option 1, if the first n PDSCHs of the multiple PDSCHs are all in the SBFD symbols, the remaining PDSCHs of the multiple PDSCHs cannot use the first type SSB symbols of the configured the SBFD subband because the first type SSB symbols have been converted to the non-SBFD symbol.
[0118] Additionally or alternatively, if a periodic downlink channel / signal (including at least one of a SPS PDSCH (Semi-Persistent Scheduling Physical Downlink Shared Channel) , a CORESET (Control Resource Set) for a PDCCH (Physical Downlink Control Channel) , or a CSI-RS (Channel State Information Reference Signal) ) is configured, and the periodic downlink channel / signal is executed based on the above Option 1 or Option 2, and a SSB symbols are configured with a SBFD subband, a BS and UE agree that if the SSB is determined to be a first type SSB, the symbols of the first type SSB configured with the SBFD subband are converted to the non-SBFD symbols in order to transmit the downlink channels / signals at different period positions based on Option 1 or Option 2.
[0119] For example, based on Option 1, if the downlink channels or signals at the first n period positions are all in the non-SBFD symbols, the downlink channels or signals at remaining period positions can use the first type SSB symbols of the configured the SBFD subband because the first type SSB symbols are converted to the non-SBFD symbols.
[0120] For example, based on option 1, if the downlink channels or signals at the first n period positions are all in SBFD symbols, the downlink channels or signals at remaining period positions cannot use first type SSB symbols of the configured SBFD subband because the first type SSB symbols are converted to the non-SBFD symbol.
[0121] In the above examples, if the SSB is determined to be a second type SSB and the second type SSB symbols are configured with a SBFD subband (including the UL subband and the DL subband) , the resources of the UL subband in the second type SSB symbols are not allowed to be used for DL reception and the resources of the UL subband in the second type SSB symbols are used for UL reception based on Examples 5 to 8 above.
[0122] Example 9-1-5. Alternatively or additionally, a BS and UE can agree that if a SSB is determined to be a second type SSB, and if a DL RBG (Resource Block Group) for a PDSCH (or a PRG of a PDSCH, or a CSI-RS resource, or a CORESET, or a RBG for a CORESET, or a CSI reporting subband) spans over the DL subband and the UL subband in the frequency domain, some resources that are part of the DL RBG (or the PRG, or the CSI-RS, or the CORESET, or the RBG, or the CSI reporting subband) in the UL subband are considered invalid.
[0123] Example 9-2. Here, this disclosure discusses the circumstance where the frequency domain resources of SSB (s) overlap with the frequency domain resources of the UL subband in the frequency domain, as shown in Figs. 8A-8C.
[0124] According to Example 9-2, if a SSB is determined to be a first type SSB and the first type SSB symbols are configured with a SBFD subband (including a UL subband and a DL subband) , the resources of the UL subband in the first type SSB symbols are not allowed to be used for UL transmission, and the resources of the UL subband are used for DL reception.
[0125] Accordingly, 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 9-1-4-2) can be applied in this circumstance.
[0126] Additionally or alternatively according to Example 9-2, if a SSB is determined to be a second type SSB and the second type SSB symbols are configured with a SBFD subband (including a UL subband and a DL subband) , the resources of the UL subband in the second type SSB symbols are not allowed to be used for UL transmission and the resources of the UL subband are used for DL reception. Likewise, the same operations or configurations as described in Examples 9-1-1, 9-1-2, 9-1-3, and 9-1-4 (including examples 9-1-4-1 and 9-1-4-2) can be applied in this circumstance.
[0127] Additionally or alternatively according to Example 9-2, if a SSB is determined to be a second type SSB and the second type SSB symbols are configured with a SBFD subband (including the UL subband and the DL subband) , the resources in the UL subband other than the resources of the SSB are not allowed to be used for DL reception and the resources in this UL subband other than the resources of the SSB are allowed to be used for UL transmission. Accordingly the operations or configurations as described in 9-1-5 can be applied.
[0128] It is noted that in the operations or configurations of Examples 6-9, while described with first type SSBs as examples, these operations or configurations are applicable if the first type SSBs are replaced with second type SSBs. Likewise, the operations or configurations of Examples 6-9, while described with first type SSB as examples, these operations or configurations is applicable when the first or second type SSBs is replaced with an unclassified SSB. In addition, certain steps to determine the types of the SSB (s) may be omitted.

But, this identification or numbering of the examples should not be a basis to treat the different examples are separated and unrelated. Instead, these examples or certain aspects of these examples can be combined together, which is also covered by the inventions of this disclosures. Additionally, each of the different examples disclosed herein may be separated as an independent invention to improve the performance of a wireless communication system, and the dependency as mentioned in the disclosure or the exemplary claims should not be used to limited the scope of the different aspects of the inventions in this disclosure.
[0130] In this discloser, various configurations, agreements, or operations between a BS and a UE is disclosed. The configurations may be configured by a BS via a configuration messages, and thereby the corresponding UE can receive the configuration message and be configured by the configuration message. Thereby, the BS and the UE can understand or predict the determination of both sides regarding various wireless transmission resources ad mentioned in the Examples above in this disclosure. In addition, the UE and BS can accordingly perform UL or DL wireless transmission according to the configurations as described in the Examples above or their combinations.

[0139] According to some examples, if symbols of an SSB are configured with an SBFD subband with an UL subband and the SSB is of a first type, symbols of the SSB are treated as not configured with an SBFD subband.
[0140] According to some examples, if symbols of an SSB are configured with an SBFD subband with an UL subband and the SSB is of a first type, symbols of the SSB are converted into non-SBFD symbols, wherein the one or more non-SBFD symbols are symbols not configured with any SBFD subband.

[0144] According to some examples, the methods further comprises receiving or transmitting all occurrences of a periodic DL channel or signal not to overlapped with the one or more converted non-SBFD.
[0145] According to some examples, if symbols of an SSB are configured with an SBFD subband with an UL subband and the SSB is of a second type, resource of the UL subband in at least one symbols of the SSB is not allowed to be used for DL reception and the resource of the UL subband in the at least one symbols of the SSB is used for UL transmission.
[0146] According to some examples, if symbols of an SSB are configured with an SBFD subband with an UL subband and the SSB is of a second type and at least one of a DL RBG for PDSCH, a PRG of PDSCH, a CSI-RS resource, a CORESET, a RBG for CORESET, or CSI reporting subband spans over a DL subband and the UL subband, the at least one of a DL RBG (Resource Block Group) for a PDSCH, a PRG of a PDSCH, a CSI-RS resource, a CORESET, a RBG for CORESET, or a CSI reporting subband is invalid.
[0147] According to some examples, if symbols of an SSB are configured with an SBFD subband with an UL subband and the SSB is of a second type, and the SSB overlaps with the UL subband or the UL subband’s guard band in the frequency domain, resource of the UL subband is allowed to be used for DL reception and the resource of the UL subband is not allowed to be used for UL transmission.

[0156] Various exemplary embodiments of the present disclosure are described herein with reference to the accompanying figures to enable a person of ordinary skill in the art to make and use the present disclosure. The present disclosure is not limited to the exemplary embodiments and applications described and illustrated herein. Additionally, the specific order and / or hierarchy of steps in the methods disclosed herein are merely exemplary approaches. Based upon design preferences, the specific order or hierarchy of steps of the disclosed methods or processes can be re-arranged while remaining within the scope of the present disclosure. Thus, those of ordinary skill in the art would understand that the methods and techniques disclosed herein present various steps or acts in exemplary order (s) , and the present disclosure is not limited to the specific order or hierarchy presented unless expressly stated otherwise.
[0157] This disclosure is intended to cover any conceivable variations, uses, combination, or adaptive changes of this disclosure following the general principles of this disclosure, and includes well-known knowledge and conventional technical means in the art and undisclosed in this application.
[0158] It is to be understood that this disclosure is not limited to the precise structures or operation described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope of this application. The scope of this application is subject only to the appended claims.
[0159] The methods, devices, processing, circuitry, and logic described above may be implemented in many different ways and in many different combinations of hardware and software. For example, all or parts of the implementations may be circuitry that includes an instruction processor or controller, such as a Central Processing Unit (CPU) , microcontroller, or a microprocessor; or as an Application Specific Integrated Circuit (ASIC) , Programmable Logic Device (PLD) , or Field Programmable Gate Array (FPGA) ; or as circuitry that includes discrete logic or other circuit components, including analog circuit components, digital circuit components or both; or any combination thereof. The circuitry may include discrete interconnected hardware components or may be combined on a single integrated circuit die, distributed among multiple integrated circuit dies, or implemented in a Multiple Chip Module (MCM) of multiple integrated circuit dies in a common package, as examples.
[0160] Accordingly, the circuitry may store or access instructions for execution, or may implement its functionality in hardware alone. The instructions may be stored in a tangible storage medium that is other than a transitory signal, such as a flash memory, a Random Access Memory (RAM) , a Read Only Memory (ROM) , an Erasable Programmable Read Only Memory (EPROM) ; or on a magnetic or optical disc, such as a Compact Disc Read Only Memory (CDROM) , Hard Disk Drive (HDD) , or other magnetic or optical disk; or 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 the medium, and the instructions when performed by the circuitry in a device may cause the device to implement any of the processing described above or illustrated in the drawings.
[0161] The implementations may be distributed. For instance, the circuitry may include multiple distinct system components, such as multiple processors and memories, and may span multiple distributed processing systems. Parameters, databases, and other data structures may be separately stored and managed, may be incorporated into a single memory or database, may be logically and physically organized in many different ways, and may be implemented in many 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 parts (e.g., subroutines or other code sections) of a single program, may form multiple separate programs, may be distributed across multiple memories and processors, and may be implemented in many different ways. Example implementations include stand-alone programs, and as part of a library, such as a shared library like a Dynamic Link Library (DLL) . The library, for example, may include shared data and one or more shared programs that include instructions that perform any of the processing described above or illustrated in the drawings, when performed by the circuitry.
[0162] In some examples, each unit, subunit, and / or module of the system may include a logical component. Each logical component may be hardware or a combination of hardware and software. For example, each logical component may include an application specific integrated circuit (ASIC) , a Field Programmable Gate Array (FPGA) , a digital logic circuit, an analog circuit, a combination of discrete circuits, gates, or any other type of hardware or combination thereof. Alternatively or in addition, each logical component may include memory hardware, such as a portion of the memory, for example, that includes instructions executable with the processor or other processors to implement one or more of the features of the logical components. When any one of the logical components includes the portion of the memory that includes instructions executable with the processor, the logical component may or may not include the processor. In some examples, each logical component may just be the portion of the memory or other physical memory that includes instructions executable with the processor or other processor to implement the features of the corresponding logical component without the logical component including any other hardware. Because each logical component includes at least some hardware even when the included hardware includes software, each logical component may be interchangeably referred to as a hardware logical component.
[0163] A second action may be said to be “in response to” a first action independent of whether the second action results directly or indirectly from the first action. The second action may occur at a substantially later time than the first action and still be in response to the first action. Similarly, the second action may be said to be in response to the first action even if intervening actions take place between the first action and the second action, and even if one or more of the intervening actions directly cause the second action to be performed. For example, a second action may be in response to a first action if the first action sets a flag and a third action later initiates the second action whenever the flag is set.
[0164] To clarify the use of and to hereby provide notice to the public, the phrases “at least one of , , …and <N>” or “at least one of , , …<N>, or combinations thereof” or “, , …and / or <N>” are defined by the Applicant in the broadest sense, superseding any other implied definitions hereinbefore or hereinafter unless expressly asserted by the Applicant to the contrary, to mean one or more elements selected from the group comprising A, B, …and N. In other words, the phrases mean any combination of one or more of the elements A, B, …or N including any one element alone or the one element in combination with one or more of the other elements which may also include, in combination, additional elements not listed.
