Technical Field

[0001] The present disclosure generally relates to wireless communication. Specifically, the present disclosure relates to methods, devices, and systems for performing cell determination based on user equipment (UE) capabilities. Background Art

[0002] Wireless communication technologies are driving the world towards an increasingly interconnected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between user equipment and multiple radio access network nodes (including but not limited to base stations). The new generation of networks is expected to provide high-speed, low-latency, and ultra-reliable communication capabilities and meet the needs of different industries and users.

[0003] The 4th Generation mobile communication technology (4G) Long-Term Evolution (LTE) or enhanced LTE (LTE-A) and the 5th Generation mobile communication technology (5G) face increasing demands. Based on current development trends, 4G and 5G systems are being developed to support the characteristics of enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC). And Carrier Aggregation (CA) can be used for both 4G and 5G and also for future communication systems.

[0004] In some embodiments, some user equipment (UE) capabilities can be reported by the UE regardless of whether the UE capabilities between several frequency bands are the same or similar. At the same time, after reporting the UE capabilities for each frequency band, the UE can be configured to reflect the corresponding UE capabilities. There are some problems with such embodiments, for example, how to more effectively use similar or identical UE capabilities to improve the efficiency of wireless communication.

[0021] The present disclosure will now be described in detail below with reference to the accompanying drawings, which form a part of the present disclosure and illustrate specific examples of embodiments by way of illustration. However, note that the present disclosure may be embodied in various different forms, and thus the subject matter covered or claimed is intended to be construed as not limited to any of the embodiments set forth below.

[0022] Throughout the specification and claims, terms may have nuanced meanings that are suggested or implied in the context in addition to the explicitly stated meanings. Similarly, the phrase "in one embodiment" or "in some embodiments" used herein does not necessarily refer to the same embodiment, and the phrase "in another embodiment" or "in other embodiments" used herein does not necessarily refer to different embodiments. The phrase "in one implementation" or "in some implementations" used herein does not necessarily refer to the same implementation, and the phrase "in another implementation" or "in other implementations" used herein does not necessarily refer to different implementations. For example, the claimed subject matter is intended to include, in whole or in part, combinations of exemplary embodiments or implementations.

[0023] In general, terms may be understood, at least in part, from their use in context. For example, terms used herein, such as "and", "or", or "and / or", may have multiple meanings, which may depend, at least in part, on the context in which they are used. Generally, "or" when used in a list, such as A, B, or C, means A, B, and C in the inclusive sense, as well as A, B, or C in the exclusive sense. Additionally, the terms "one or more" or "at least one" used herein may, at least in part, depend on the context, be used to describe any feature, structure, or characteristic in the singular sense, or may be used to describe a combination of features, structures, or characteristics in the plural sense. Similarly, terms such as "a", "an", or "the" may also be understood to convey either a singular usage or a plural usage, at least in part, depending on the context. Further, the terms "based on" or "determined by" may be understood to not necessarily imply an exclusive set of factors, but may allow for the presence of additional factors that are not necessarily explicitly described, again, at least in part, depending on the context.

[0024] This disclosure describes methods, systems, and devices for performing cell determination based on user equipment (UE) capabilities.

[0025] The New Generation (NG) mobile communication system is pushing the world towards an increasingly interconnected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between user equipment and radio access network nodes (including, but not limited to, radio base stations). The new generation of networks is expected to provide high-speed, low-latency, and ultra-reliable communication capabilities and meet the needs of different industries and users.

[0026] The fourth-generation mobile communication technology (4G) Long-Term Evolution (LTE) or Enhanced LTE (LTE-A) and the fifth-generation mobile communication technology (5G) are facing increasing demands. Based on current development trends, 4G and 5G systems are being developed to support the characteristics of enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC). In some embodiments, coverage enhancement may be a requirement for 4G, 5G, and / or next-generation communication systems.

[0027] In some wireless communication systems, UE capability reporting can be per UE, per frequency band, per band combination (BC), per feature set (FS), or per component carrier of each feature set (FSPC). In other words, UE capability parameters can have a hierarchical structure. For example, in a UE capability parameter table, "per level" indicates the level relative to which the associated parameter is included. "Per UE" can indicate that the associated parameter is signaled per UE. "Per frequency band" indicates that it is signaled according to the frequency band. "Per BC" can indicate that it is signaled per band combination. "Per FS" can indicate that it is signaled per feature set (or per band of each band set). "Per FSPC" can indicate that it is signaled per component carrier of each feature set (or per component carrier (CC) of each band of each band set). In some embodiments, "per FD" can indicate referring to the associated field description.

[0028] In some embodiments, for each frequency band, some per-band UE capabilities can be reported by the UE, regardless of whether the per-band UE capabilities among several frequency bands are the same or similar. Also, after reporting the UE capabilities for each frequency band, the radio resource control (RRC) configuration for the UE can be configured per cell or carrier to reflect the corresponding UE capabilities (if any). There are some problems with such embodiments. For example, how to use similar or identical UE capabilities more effectively to improve the efficiency of wireless communication.

[0029] This disclosure describes various embodiments for performing cell determination based on user equipment (UE) capabilities, thus solving at least one problem / issue discussed in this disclosure.

Each UE may communicate wirelessly with the wireless network node via one or more wireless channels 115 for uplink / downlink communication. For example, the first UE 110 may communicate wirelessly with the wireless network node 118 via a channel including a plurality of wireless channels during a specific time period. The network base station 118 may send high-layer signaling to the UE 110. The high-layer signaling may include configuration information for communication between the UE and the base station. In one implementation, the high-layer signaling may include radio resource control (RRC) messages.

The parameters 328 may provide and specify configuration and operation options for the instructions 326. The memory 322 may also store any BT, WiFi, 3G, 4G, 5G, 6G, or other data that the UE 300 will send or has received via the communication interface 302. In various embodiments, the system power for the UE 300 may be provided by a power storage device (such as a battery or a transformer, etc.).

Based on one or more shared / same UE capabilities, a soft cell may be a cell including one or more frequency resource units (or referred to as spectrum blocks), which may include a legacy carrier, cell, or band.

[0055] Refer to Figure 4A , the present disclosure describes various embodiments of a method 400 for wireless communication. The method 400 may be performed by a wireless communication device (e.g., a user equipment). The method 400 may include step 410: reporting at least one UE capability for determining a cell, where the cell includes one or more frequency resource units based on the at least one UE capability.

[0074] Set of Embodiments One

[0075] This disclosure describes various embodiments for performing cell determination based on user equipment (UE) capabilities, where there can be two basic soft cell structures: one is a cell-specific soft cell as shown in Figure 5A and the other is a UE-specific soft cell as shown in Figure 5B The cell-specific soft cell can be defined or configured from the perspective of the gNB. As shown in

[0076] , multiple frequency bands are included in a cell, and for all UEs, the corresponding UE capabilities are supported. In some embodiments, the UE capabilities can be reported by the UEs supporting the cell including multiple frequency bands, or can be mandatory. Figure 5A

[0077] The UE-specific soft cell can be defined or configured by the gNB and is based on UE capabilities. As shown in Figure 5B , multiple frequency bands are included in a cell, and for different UEs supporting one or more corresponding UE capabilities, the number of multiple frequency bands in a soft cell may be different based on the UE capability report of each UE and / or gNB configuration. In some embodiments, the UE capabilities can be reported by the UEs supporting the cell including multiple frequency bands, or can be mandatory.

[0078] ​In various embodiments / implementations, the term "soft cell" or "cell" may be used to refer to UE-specific soft cells and / or cell-specific soft cells. In some implementations, a soft cell may include a soft carrier, which includes discontinuous frequency resources from multiple frequency bands, optionally, by one or more Bandwidth Parts (BWPs). In some implementations, the soft carrier may be a Downlink (DL) carrier or an Uplink (UL) carrier, or a carrier including both DL and UL resources. In some implementations, a soft cell may include a soft BWP, which includes discontinuous frequency resources from multiple frequency bands. In some implementations, the soft BWP may be a DL BWP or a UL BWP, or a BWP including both DL resources and UL resources.

[0079] In some implementations, a soft cell may be defined or configured in one of the following ways. For one method, the soft cell is defined / supported / configured only for Secondary Cell (SCell) enhancement, where the soft cell is constructed by aggregating multiple SCells. For another method, the soft cell is defined / supported / configured for Primary Cell (PCell) or one cell enhancement, where the soft cell is constructed by aggregating multiple anchor cells. For yet another method, the soft cell is defined / supported / configured for one or more cell enhancements, where the soft cell is constructed by aggregating multiple frequency bands.

[0080] In some implementations, initial access may be supported by a soft cell. One or more frequency bands within the soft cell may be used for Synchronization Signal and Physical Broadcast Channel (PBCH) blocks (SS / PBCH Block, SSB) or broadcast transmission. One or more frequency bands may be used for Physical Random Access Channel (PRACH) or msg3 transmission. As a non-limiting example, one frequency band within the soft cell may be used for SSB or broadcast transmission, while all frequency bands within the soft cell may be used for PRACH or msg3 transmission. In some implementations, PRACH may be transmitted on one or more frequency bands at a time, where the UE transmits PRACH based on its ability of the soft cell having all or part of the frequency bands.

[0081] In some embodiments, paging can be transmitted on a BWP / carrier / band different from the BWP / carrier / band used in the RRC connected state. As a non - limiting example, for a UE in the RRC connected state, multiple bands within a soft cell are used for DL / UL traffic transmission, and the carrier / band for paging within the soft cell is different from any of the multiple bands used for DL / UL traffic transmission within the soft cell. There are benefits associated with these embodiments, such as saving network energy or UE power, where energy or power can be saved when the UE is in a state without traffic transmission.

[0082] In some embodiments, for cell - specific soft cells, gNB management may be simpler. For one soft cell, the joining / release of different UEs may make no difference. However, for UE implementation, this may be more challenging.

[0083] In some embodiments, for UE - specific soft cells, it may be more friendly to different UEs with different capabilities. However, gNB management may be more complex. As a non - limiting example, for the same shared band set including multiple bands, single - cell scheduling can be used for one UE, while carrier / cell aggregation can be used for another UE.

[0084] The various embodiments described in this disclosure can have the following benefits: restricting RRC configuration based on shared UE capabilities and reducing UE complexity, where a soft cell is a cell that includes one or more traditional carriers / cells / bands based on one or more shared / same UE capabilities; and the soft cell can be a cell - specific or UE - specific cell obtained by aggregating multiple SCell or multiple anchor cells.

[0085] Set of Embodiments Two

[0086] This disclosure describes various embodiments for performing cell determination based on user equipment (UE) capabilities, where, to support soft cells, one or more shared / same UE capabilities can include at least one of the following UE capabilities by band / FS / FSPC.

[0087] For non-limiting examples in some embodiments, one or more UE capabilities by frequency band may include similar / same Multiple-Input Multiple-Output (MIMO) capabilities, i.e., additionalActiveTCI-StatePDCCH, aperiodicBeamReport, and / or multipleTCI (multi-TCI), and when the same subcarrier spacing (SCS) is 15KHz, bwp-DiffNumerology (BWP different data sets), bwp-SameNumerology (BWP same data sets) are as shown in Table 3.

[0107] Indicates whether the UE supports PDSCH processing capability 2. The UE supports this capability only when all serving cells are self-scheduled and all serving cells in a band with processingType2 (processing type 2) configured by the network use the same subcarrier spacing. The signaling of this capability includes the following parameters for each subcarrier spacing supported by the UE.

[0108] -fallback indicates that when the configured number of carriers is greater than the numberOfCarriers for the reported value of differentTB-PerSlot (different Transport Block (TB) per slot)

[0109] TB (Transport Block)

[0110] Whether it supports PDSCH processing capability 2. If fallback ='sc', the UE supports the processing time of capability 2 on the lowest cell index among the configured carriers in the band of the reported value. If fallback = 'cap1-only', the UE only supports capability 1 in the band of the reported value;

[0111] - differentTB-PerSlot indicates whether the UE supports processing type 2 for 1, 2, 4, and / or 7 unicast PDSCHs per time slot of a CC and for different transport blocks; if supported, it further indicates the maximum number of CA serving cells on which the UE can support that number of unicast PDSCHs for different TBs. If pdsch-ProcessingType2 is indicated, the UE shall include at least one of the numberOfCarriers for 1, 2, 4, or 7 transport blocks per time slot in this field.

[0112] For non-limiting examples in some embodiments, in response to similar / same MIMO / Modem / SCS capabilities, one or more UE capabilities according to FSPC may include maxNumberMIMO-LayersPDSCH (the maximum number of MIMO layers of PDCCH), supportedBandwidthDL (supported DL bandwidth), supportedModulationOrderDL (supported DL modulation order), supportedSubCarrierSpacingDL (supported DL subcarrier spacing), as shown in Table 5.

[0113] Table 5: FeatureSetDownlinkPerCC (Downlink feature set according to CC) parameters

[0114] Definition of parameters

[0115] maxNumberMIMO-LayersPDSCH

[0116] Defines the maximum number of (one or more) spatial multiplexing layers supported by the UE for DL reception. For single-CC stand-alone NR, signaling of the capability to support at least 4 MIMO layers in the band (in the band where 4 Rx (Receivers) must be specified for a given UE) and at least 2 MIMO layers in FR2 is mandatory. If not present, the UE does not support MIMO on this carrier.

[0117] supportedBandwidthDL

[0118] Indicates the maximum DL channel bandwidth supported by the UE for a given SCS within a single CC.

[0119] For FR1, as predefined for each band, all bandwidths shall enforce a single CC, unless indicated as optional. For FR2, the set of mandatory CBWs is 50, 100, 200 MHz. When this field is included in a band combination with a single band entry and a single CC entry (i.e., a non-CA band combination), the UE shall indicate the maximum channel bandwidth for that band according to predefined conditions.

[0120] Note: To determine whether the UE supports a channel bandwidth of 90 MHz, the network may ignore this capability and instead verify channelBW-90mhz (channel bandwidth of 90 MHz) and supportedBandwidthCombinationSet (supported bandwidth combination set). For serving cells with other channel bandwidths, the network will verify channelBWs-

[0121] DL (DL channel bandwidth), supportedBandwidthCombinationSet, and supportedBandwidthDL

[0122] (supported DL bandwidth).

[0123]

[0124]

[0125] supportedSubCarrierSpacingDL

[0126] The supported subcarrier spacing for DL defined by the UE, as predefined, indicates that the UE supports simultaneous reception while using the same or different data sets in CA. In FR1 and FR2, for in-band NR CA (including contiguous and non-contiguous CA), support for simultaneous reception while using the same data set is mandatory in terms of capabilities. If the UE supports inter-band NR CA including both (one or more) FR1 bands and (one or more) FR2 bands, support for simultaneous reception between (one or more) FR1 bands and (one or more) FR2 bands in DL while using two different data sets is mandatory in terms of capabilities. For other cases, it is optional. For other cases, support for simultaneous reception while using different data sets in CA is optional.

[0127] In some embodiments, to support soft cells, one or more UE capabilities may be reported per band set, where reporting per band set is a level between reporting per band and reporting per BC. For example, BC is reported for carrier aggregation (CA), where one or more band sets are used to combine soft cells. Alternatively, for soft cells, one or more UE capabilities are reported per BC.

[0128] In some embodiments, it may be reported whether soft cell support is available based on UE parameters. In some embodiments, there may be no difference for FR1 and FR2, or only for FR1. In some embodiments, the UE may report the supported band sets per UE or per BC, e.g., report the band sets per UE or per BC via a subset of the band list.

[0129] In some embodiments, UE capability parameters may be reported by one of the following alternative methods. For one method, a single value may be reported per band set. For another method, a single value may be reported for each band, which is similar to the conventional method. For yet another method, a single value and multiple variations (or offset values) may be reported for one band set, where the single value serves as a reference value for one band in the band set, and each of the multiple variations serves as an offset value for each of the other bands in the band set (or for each band in the band set).

[0130] As a non - limiting example, when the maximum number of active CGs in the BWP of a cell is at most 12 and reporting is per band, for a soft cell, reporting may be done as follows. For one method, the total maximum number (e.g., 30) of the soft cell (or band set) is reported for the band set. For another method, the same maximum number (e.g., 10) for each band of the soft cell is reported. For yet another method, the maximum number of a reference band of the soft cell with variations (e.g., - 4, - 2, 0, 2, or 4) for each of the remaining bands (e.g., 10 for the first band in the band set, 2 and 4 for the second and third bands) is reported.

[0131] The various embodiments described in this disclosure may have the following benefits: restricting RRC configuration and reducing UE capability reporting, where a soft cell is a cell that includes one or more traditional carriers / cells / bands based on one or more shared / same UE capabilities; and a soft cell may be a cell - specific or UE - specific cell, which is obtained by aggregating multiple SCell or multiple anchor cells.

[0132] Set of Embodiments Three

[0133] The present disclosure describes various embodiments for performing cell determination based on user equipment (UE) capabilities, wherein, to support soft cells, the configuration of a soft cell may be based on the serving cell level, and the bandwidth part (BWP) configuration may be one of the following options.

[0134] For one option (Option 1), one BWP is configured to include one frequency band. In some embodiments, at most one active BWP may be configured in a cell; or multiple active BWPs may be configured in a cell, where each BWP may include one frequency band.

[0135] For another option (Option 2), one BWP is configured to include multiple frequency bands. In some embodiments, at most one active BWP may be configured in a cell, and the UE may support the capability of CA; or more than one active BWP may be configured in a cell, where multiple BWPs may overlap.

[0136] In some embodiments, there is only one aggregated DL carrier and / or only one aggregated UL carrier in a soft cell. In some embodiments, the aggregated DL or UL carrier may be a soft carrier, which includes discontinuous frequency resources from multiple frequency bands, optionally composed of one BWP or multiple BWPs. In some embodiments, a soft cell may include a soft carrier containing both DL resources and UL resources. In some embodiments, a soft cell may include a soft BWP, which includes discontinuous frequency resources from multiple frequency bands. In some embodiments, the soft BWP may be a DL BWP or a UL BWP, or a BWP including both DL resources and UL resources.

[0137] In some embodiments, for a soft cell, the RRC parameter configuration may be one of the following alternatives. For one alternative (Alt.1), the RRC parameters are configured to have a single value for a BWP with an aggregated bandwidth having a set of frequency bands. For another alternative (Alt.2), the RRC parameters are configured to have a single value for a BWP with continuous frequency resources. For another alternative (Alt.3), the RRC parameters are configured to have a single value for multiple BWPs or frequency bands, and a variation amount or offset value for each (remaining) BWP or frequency band within the set of frequency bands. For example, based on Option 1, Alt.2 or Alt.3 may be applied; and / or based on Option 2, Alt.1 may be applied.

[0138] Taking the RRC parameters configured with authorization type 1 as a non-limiting example, the frequencyDomainAllocation (frequency domain allocation) can be configured by one of the following alternatives. Alt.1 A bit string (e.g., 30 bits) for the aggregated BWP of the frequency band set can be configured. Alt.2 A bit string per BWP (e.g., 18 bits) can be configured; Alt.3 A bit string (e.g., 18 bits) for indicating the allocation of the remaining resource block groups (RBGs) for the reference BWP or the frequency band set and additional bits as variable values (e.g., 2 bits for each (remaining) BWP or frequency band) can be configured.

[0139] The various embodiments described in this disclosure may have the following benefits: restricting RRC configuration and reducing UE capability reporting, where a soft cell is a cell that includes one or more legacy carriers / cells / frequency bands based on one or more shared / same UE capabilities; and the soft cell can be a cell-specific or UE-specific cell, which is obtained by aggregating multiple SCell or multiple anchor cells.

[0140] Set of embodiments four

[0141] This disclosure describes various embodiments for performing cell determination based on user equipment (UE) capabilities, where, for operations on a soft cell, such as scheduling, (re)transmission, Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) feedback, and single aggregated BWP and multiple BWP operations can be performed.

[0142] In some embodiments, for scheduling, when scheduling based on a single cell, the UE can be scheduled within the aggregated bandwidth of the frequency band set, where wideband scheduling can be performed. The RBG for each BWP and the RBG for the aggregated bandwidth can be configured independently. The frequency order of the aggregated bandwidth (including the indexes of RBs, RBGs, BWPs, etc.) can be configured explicitly or according to the default configuration obtained by the ascending frequency positions. When scheduling based on multiple cells, the UE can be scheduled within the frequency band set (or soft cell) similar to the cell set configured in multi-cell scheduling, while some type 2 fields (including the independent indication field) can be optimized by one of the following options: Option 1, indicating a single value and applying it to all BWPs (or frequency bands); Option 2, indicating a single value and applying it to the reference BWP (or frequency band) and the variable values for each (remaining) BWP (frequency band); and / or Option 3, indicating a row of the joint code RRC table for all BWPs (or frequency bands).

[0143] In some embodiments, for transmission or retransmission, when scheduling is based on a single cell, the UE can be scheduled within the aggregated bandwidth of a set of frequency bands, where wideband scheduling can be performed. A single transport block (TB) can be generated per soft cell (or set of frequency bands), or a single TB with code block groups (CBGs) can be generated, where each CBG is applied to each BWP (or frequency band). When scheduling is based on multiple cells, the UE can be scheduled within a set of frequency bands (or soft cells) similar to the set of cells configured in multi-cell scheduling with different TBs. In some embodiments, different TBs can be generated on different BWPs (or frequency bands). In some embodiments, retransmission can be performed on different BWPs (or frequency bands) using HARQ entities shared in the soft cell.

[0144] In some embodiments, for HARQ-ACK feedback, when scheduling is based on a single cell, the UE can be scheduled within the aggregated bandwidth of a set of frequency bands, where wideband scheduling can be performed. A codebook at the TB or CBG level can be used for transmission; or HARQ-ACK feedback at the BWP (or frequency band) level can be used, which can be obtained from the CBG group, e.g., one HARQ-ACK bit corresponding to the set of CBGs for the BWP (or frequency band). When scheduling is based on multiple cells, the UE can be scheduled within a set of frequency bands (or soft cells) similar to the set of cells configured in multi-cell scheduling, where the HARQ-ACK bits for each cell are within the same PUCCH group. In some embodiments, a codebook at the TB level can be used for each BWP (or frequency band) within the soft cell (or set of frequency bands).

[0145] In some embodiments, the operation of (de)activating a soft cell can be performed only based on the BWP level or the carrier level, or based on a combination of both the cell level and the BWP level or the carrier level, and any one of them can be further independently combined with the DL and UL BWP / carrier / cell / band. Option 1, the soft cell can be always activated, and the BWP (or band) within the soft cell (or set of bands) can be activated / deactivated by signaling (e.g., Downlink Control Information (DCI), or RRC or Medium Access Control (MAC) Control Element (CE)). In some embodiments, one or more BWPs (or bands) can be sequentially added / released to / from the soft cell. Option 2, the soft cell can be activated / deactivated, and the activated soft cell can include one or more BWPs (or bands), and the one or more BWPs (or bands) can also optionally be applied to the deactivated soft cell. In some embodiments, soft cell handover can be performed using the independent band sets of each soft cell and based on L1 or L2 or L3 signaling. In some embodiments, it is further independently combined with the DL and UL BWP / carrier / cell / band. As a non-limiting example, for a cell with DL BWP#0 / 1 / 2 / 3 and UL BWP#0 / 1, when the UL traffic is low, only UL BWP#1 is deactivated, or when the UL traffic is high, only UL BWP#2 is activated.

[0146] The various embodiments described in this disclosure can have the following benefits: restricting RRC configuration and reducing UE capability reporting, where a soft cell is a cell that includes one or more traditional carriers / cells / bands based on one or more shared / same UE capabilities; and the soft cell can be a cell-specific or UE-specific cell, which is obtained by aggregating multiple SCell or multiple anchor cells.

[0147] Set of Embodiments Five

[0148] This disclosure describes various embodiments of performing cell determination based on the capabilities of a User Equipment (UE), where the enhancement for band set operation is UL Tx handover enhancement, which can be performed based on a soft cell. In some embodiments, UL Tx handover based on BWP (or band) or carrier can be applied in the soft cell, and one or more carriers can share one Tx.

[0149] In some embodiments, when Tx per band is continuously applied, whether within a cell or not, handover can be performed between multiple BWPs or carriers or bands. Option 1: Perform handover based on BWP / carrier / band regardless of the carrier type. The UL Tx handover for multiple BWPs / carriers / bands of a cell can be operated according to the handover manner of carrier aggregation configured with band combination. A non-limiting example includes the band combination for a cell and optionally for UL Tx handover, i.e., BandCombinationForOneCell-UplinkTxSwitch (band combination for one cell - uplink Tx handover). Option 2: Perform handover based on BWP / carrier / band with some restrictions for one or more carriers within the cell. Alt.1: The supplementary uplink (SUL) carrier may not support parallel transmission with any other normal uplink (NUL) carrier. In this case, all NUL carriers within the cell are the corresponding NUL carriers defined / configured for the SUL. Alt.2: The SUL carrier may not support parallel transmission with a corresponding NUL carrier. In this case, one of the NUL carriers within the cell is the corresponding NUL carrier defined / configured for the SUL. Alt.3: Whether the SUL carrier and the (non-)corresponding NUL carrier support parallel transmission is configurable based on the RRC configuration. Alt.4: When there are more than one SUL carriers in the cell, in addition to Alt.3, whether the SUL carriers support parallel transmission with other SUL carriers is also configurable.

[0150] In some embodiments, when Tx per band set is applied, whether within a cell or not, handover between band sets can be performed.

[0151] In some embodiments, a set of bands (or a band set) can be obtained through RRC configuration or predefined in the specification, or obtained through 0us handover period configuration. In some embodiments, some restrictions include at least one of the following items. Alt.1: One or more BWPs / carriers on different bands among multiple BWPs / carriers within a cell can be grouped into a band set. As Figure 6As shown, Tx for a set of frequency bands and more BWPs / carriers can be used for UL transmission for a UE with up to 2 Tx. In some embodiments, multiple BWPs / carriers on different frequency bands in a cell can be a set of frequency bands, where the Tx per cell includes multiple frequency bands. Alt.2: Only the carriers on different frequency bands within a cell can be configured as a set of frequency bands, where a normal cell may not support this set of frequency bands. When the carriers of the frequency bands within a cell are defined / configured / from BC, the set of frequency bands can only be configured within a frequency band combination (-UplinkTxSwitch (uplink Tx switching)). When the carriers of the frequency bands within a cell are defined / configured from more than one BC, this set of frequency bands may come from different BCs. Alt.3: When at least one carrier is a SUL carrier, the set of frequency bands may only include the same type of frequency bands, where a set of frequency bands with both NUL and SUL frequency bands may not be permitted.

[0152] In some embodiments, another scheme for obtaining a virtual frequency band or a set of frequency bands can include configuring the switching period for a frequency band pair or a frequency band combination to be equal to 0 microseconds (us). For a non-limiting example as Figure 6 shown, the switching period of frequency bands B and C (i.e., T_switch from B to C (T_switchB-C)) is configured to 0 us, and a set of frequency bands or a virtual frequency band including frequency bands B and C is generated.

[0153] In some embodiments, for UL Tx switching, it can be performed based on at least one BWP / carrier on a set of frequency bands or a virtual frequency band, where the Tx switching can be performed across different sets of frequency bands. For a non-limiting example, for a UE indicating the uplink capability for using BandCombination-UplinkTxSwitch for a frequency band combination, and when configuring this frequency band combination to have multiple uplink carriers in the serving cell using the high-layer parameter uplinkConfigList (uplink configuration list) and each uplinkConfig (uplink configuration) associated with bandSetid (set of frequency band identifier): when the UE is configured for the uplink using the parameter uplinkTxSwitching, and when the UE is going to transmit on the uplink based on the (one or more) DCI received before T0-T offset or based on the (one or more) high-layer configurations: when the UE is going to transmit a 2-port transmission on one uplink carrier on a set of frequency bands, and the previous uplink transmission was a 1-port transmission on another uplink carrier on another set of frequency bands, it may not be desirable for the UE to perform a transmission with a duration of N Tx1-Tx2 on any carrier.

[0154] In some embodiments, for a handover period, it can be reported based on a pair of frequency bands or a pair of sets of frequency bands. When based on a pair of frequency bands, the handover gap can be determined by the maximum handover period of the pair of frequency bands involved in the handover of the set of frequency bands. For a non-limiting example as Figure 6 shown, the handover gap is determined by Max{T_switchA-B, T_switchA-C, T_switchB-C} (the maximum value among T_switchA-B, T_switchA-C, and T_switchB-C) or Max{T_switchA-B, T_switchA-C}; and in some embodiments, T_switchB-C can be 0 us. In some embodiments, the handover period between any one of the frequency bands in a set and another frequency band may be the same. When based on a set of pairs of frequency bands, the set of frequency bands is defined / configured, and the handover period of the pair of sets of frequency bands is reported or configured. As a non-limiting example, uplinkTxSwitchingPeriodofBandSet (the uplink Tx handover period of the set of frequency bands) is introduced to represent the handover period of the pair of sets of frequency bands.

[0155] The various embodiments described in the present disclosure may have the following benefits: facilitating the UE to use multiple fragmented and adjacent spectrum resources, where multiple carriers are in different frequency bands, and the number of Tx for the UE can be limited to at most 2; and using Tx by frequency band set facilitates the UE to use more BWPs / carriers / frequency bands in one or more cells, where a soft cell is a cell that includes one or more legacy carriers / cells / frequency bands based on one or more shared / same UE capabilities.
