To facilitate the implementation of different data services and needs, the elements of 5GC (also known as network functions) have been simplified, some based on software and others on hardware, for customization as required.

[0028] 1. Mobile communication technology and environment
[0029] Figure 1 An example wireless communication network and / or system 100 according to one embodiment of this disclosure is illustrated, in which the techniques disclosed herein can be implemented. In the following discussion, wireless communication network 100 can be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 100". Such an example network 100 includes base station 102 (hereinafter referred to as "BS102"; also referred to as a wireless communication node) and user equipment device 104 (hereinafter referred to as "UE104"; also referred to as a wireless communication device) that can communicate with each other via communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 covering a geographic area 101. Figure 1 In this context, BS102 and UE104 are contained within their respective geographical boundaries in cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating with its allocated bandwidth to provide sufficient radio coverage to its intended users.
[0030] For example, BS102 can operate with allocated channel transmission bandwidth to provide sufficient coverage to UE 104. BS102 and UE 104 can communicate via downlink radio frame 118 and uplink radio frame 124, respectively. Each radio frame 118 / 124 can be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, BS102 and UE 104 are described herein as non-limiting examples of "communication nodes" that can generally implement the methods disclosed herein. According to various embodiments of this solution, such communication nodes may be able to perform wireless and / or wired communication.
[0031] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of this solution is shown. System 200 may include components and elements configured to support known or conventional operating features that do not need to be described in detail herein. In one illustrative embodiment, as described above, system 200 can be used in applications such as... Figure 1 In the wireless communication environment 100, data symbols are conveyed (e.g., transmitted and received).
[0032] System 200 typically includes a base station 202 (hereinafter referred to as "BS202") and a user equipment unit 204 (hereinafter referred to as "UE204"). BS202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with each other as needed via a data communication bus 220. UE204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with each other as needed via a data communication bus 240. BS202 communicates with UE204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described herein.
[0033] As will be understood by those skilled in the art, system 200 may also include, in addition to Figure 2 Any number of modules other than those shown. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are typically described according to their functionality. Whether such functionality is implemented as hardware, firmware, or software can depend on the specific application and design constraints imposed on the system as a whole. Those skilled in the art can implement such functionality appropriately for each specific application; however, such implementation decisions should not be construed as limiting the scope of this disclosure.
[0034] According to some embodiments, UE transceiver 230 may be referred to herein as "uplink" transceiver 230, which includes a radio frequency (RF) transmitter and an RF receiver, each of which includes circuitry coupled to antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time-duplex manner. Similarly, according to some embodiments, BS transceiver 210 may be referred to herein as "downlink" transceiver 210, which includes an RF transmitter and an RF receiver, each of which includes circuitry coupled to antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 can be coordinated in time such that the uplink receiver circuitry is coupled to the uplink antenna 232 so that transmissions are received via wireless transmission link 250 at the same time the downlink transmitter is coupled to the downlink antenna 212. Conversely, the operation of the two transceivers 210 and 230 can be coordinated in time such that the downlink receiver is coupled to the downlink antenna 212 so that transmissions are received via the wireless transmission link 250 at the same time the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is tight time synchronization with a minimum guard time between changes in duplex direction.
[0035] UE transceiver 230 and base transceiver 210 are configured to communicate via wireless data communication link 250 and cooperate with RF antenna arrangements 212 / 232 that are appropriately configured to support specific wireless communication protocols and modulation schemes. In some illustrative embodiments, UE transceiver 210 and base transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that this disclosure is not necessarily limited to the application of specific standards and related protocols. Rather, UE transceiver 230 and base transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.
[0036] According to various embodiments, for example, BS202 may be an evolved Node B (eNB), a serving eNB, a target eNB, a femtocell, or a picocell. In some embodiments, UE 204 may be implemented in various types of user equipment, such as mobile phones, smartphones, personal digital assistants (PDAs), tablets, laptops, wearable computing devices, etc. Processor modules 214 and 236 may be implemented or realized using a general-purpose processor, content-addressable memory, a digital signal processor, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof (designed to perform the functions described herein). In this way, the processor may be implemented as a microprocessor, a controller, a microcontroller, a state machine, etc. The processor may also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors combined with a digital signal processor core, or any other such configuration.
[0037] Furthermore, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein can be directly embodied in hardware, firmware, software modules executed by processor modules 214 and 236 respectively, or in any practical combination thereof. Memory modules 216 and 234 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 can be coupled to processor modules 210 and 230 respectively, such that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234 respectively. Memory modules 216 and 234 can also be integrated into their respective processor modules 210 and 230. In some embodiments, memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by processor modules 210 and 230 respectively. Memory modules 216 and 234 may each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.
[0038] Network communication module 218 typically refers to the hardware, software, firmware, processing logic, and / or other components of base station 202 that support bidirectional communication between base station transceiver 210 and other network components and communication nodes configured to communicate with base station 202. For example, network communication module 218 may be configured to support Internet or WiMAX services. In a typical deployment, but not limited to, network communication module 218 provides an 802.3 Ethernet interface, enabling base station transceiver 210 to communicate with legacy Ethernet-based computer networks. In this way, network communication module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)). The terms “configured for,” “configured to,” and their conjugates, used herein with respect to a particular operation or function, refer to devices, components, circuits, structures, machines, signals, etc., that are physically constructed, programmed, formatted, and / or arranged to perform a particular operation or function.
[0039] The Open Systems Interconnection (OSI) model (referred to herein as the "OSI model") is a conceptual and logical layout that defines network communications used by systems (e.g., wireless communication devices, wireless communication nodes) that are open to interconnecting and communicating with other systems.

[0041] 2. Systems and methods for common channels and signals
[0042] Wireless communication services are covering an increasing number of application scenarios. Fifth-generation (5G) systems support Frequency Division Duplex (FDD) and Time Division Duplex (TDD) as two typical radio frame structures. In FDD scenarios, the gNB (base station) can simultaneously schedule uplink and downlink transmissions. In some embodiments, in TDD scenarios, the gNB can simultaneously schedule only one type of transmission. When (e.g., in response to) a TDD radio frame structure being configured and the uplink time slot is far from the downlink time slot, the UE may not be able to provide timely feedback on the received Physical Downlink Shared Channel (PDSCH). In TDD scenarios, the timing gap (delay) between DL reception and UL transmission can be much larger than the timing gap in FDD. Full-duplex (FD) XDD is employed to address / handle such problems. By using FD XDD at the base station, UL and DL signals can be received and transmitted on overlapping frequency resources. In XDD scenarios, TDD time slots can be configured with resources for one type / direction (DL / UL) of transmission for another type / direction (UL / DL). For example (e.g.) Figure 3 As shown, the network can configure some resource elements in the frequency domain of the downlink TDD time slot as uplink frequency resources.
[0043] In current 5G systems, when the subcarrier spacing (SCS) is 15kHz, the bandwidth portion (BWP) of the control resource set (CORESET or CORESET0 for Type 0 physical downlink control channel common search space) can occupy at least 24 resource blocks (RBs) in the frequency domain. The network can configure the initial downlink BWP such that it can encompass the entire CORESET0 in the frequency domain. If no initial downlink BWP is provided to the UE, it can be defined by location and multiple consecutive physical resource blocks (PRBs). The number of consecutive PRBs can start from the PRB with the lowest index and end at the PRB with the highest index in CORESET0.
[0044] Because the bandwidth of some common / shared channels or signals (e.g., the control resource set for the common search space of the Type 0 physical downlink control channel (CORESET0 for Type 0-PDCCH CSS), the downlink initial bandwidth portion (BWP), or the uplink initial BWP) cannot be dynamically configured, conflicts may exist between cross-segmented duplex (XDD) time slots and some common channels and / or signals. Common / shared channels or signals are used for communication between a cell (BS) and one or more UEs. In some embodiments, the base station may cut off (e.g., allocate / reserve / configure) a large downlink (DL) bandwidth of a downlink time slot to use as uplink (UL) bandwidth in a cross-segmented duplex (XDD) time slot. In some embodiments, the base station may cut off (e.g., allocate / reserve / configure) a large uplink (UL) bandwidth of an uplink time slot to use as downlink (DL) bandwidth in a cross-segmented duplex (XDD) time slot. Therefore, how to protect the transmission of common channels / signals in XDD time slots is a problem recognized by this disclosure and for which solutions are provided to address. The systems and methods presented herein include novel mechanisms for frequency domain adjustment. Based on the concepts of this invention, various aspects / features / elements from the various examples / paragraphs disclosed herein can be combined and / or reordered, and are by no means limited to the examples described herein.
[0045] Regarding the example implementation, Chapter 1
[0046] In some embodiments, the gNB (BS) can operate in full-duplex mode, and the UE can operate in half-duplex mode. The gNB (BS) can simultaneously transmit downlink transmissions and receive uplink transmissions. On the other hand, the UE can only transmit uplink transmissions or receive downlink transmissions at any given time.
[0047] In some embodiments, the gNB (BS) can operate in full-duplex mode, and the UE can also operate in full-duplex mode. The gNB (BS) can simultaneously transmit downlink transmissions and receive uplink transmissions. Furthermore, the UE can transmit uplink transmissions and receive downlink transmissions at a certain point in time (e.g., simultaneously or at least partially overlapping in time).
[0048] Now for reference Figure 4 In at least one XDD time slot, some downlink bandwidth of the downlink time slot is cut off by the BS (e.g., allocated / reserved / configured) to be used as uplink bandwidth. XDD is a duplexing method where duplexing can be implemented in the time domain, frequency domain, or both domains within a single TDD carrier, as needed / configured / implemented. Figure 4 In the BS, the TDD downlink bandwidth resource block can be configured for uplink transmission. Figure 4 The illustrative XDD time slots in the diagram include two downlink bandwidths (e.g., frequency subbands or bands) and one uplink bandwidth. In some embodiments, an XDD time slot may include more than one uplink bandwidth. In some embodiments, an XDD time slot may include more than three bandwidths. Unless otherwise explicitly stated, this solution is not limited to the specific bandwidth order or number of bandwidths presented. The gNB (BS) can schedule non-overlapping resources (in the frequency domain) to the cell edge terminal (UE) so that downlink and uplink transmissions can occur in / at the same time instance. In other words, when downlink transmissions are performed on the gNB side to simultaneously serve other users (e.g., other UEs), the cell edge terminal (UE) can be assigned to transmit continuously on uplink resources.
[0049] Now for reference Figure 5 In at least one XDD timeslot, some uplink bandwidth (e.g., frequency subband or band) of the uplink timeslot is cut off by the BS (e.g., allocated / reserved / configured) to be used as downlink bandwidth. Figure 5 In the BS, the TDD uplink bandwidth resource block can be configured for downlink transmission. Figure 5The example XDD time slot includes two uplink bandwidths and one downlink bandwidth. In some embodiments, an XDD time slot may include more than one downlink bandwidth. In some embodiments, an XDD time slot may include more than three bandwidths. Unless otherwise explicitly stated, this solution is not limited to the specific bandwidth order or number of bandwidths presented. The gNB (BS) can schedule non-overlapping resources (in the frequency domain) to the cell edge terminal (UE) so that downlink and uplink transmissions can occur in the same time instance. In other words, when downlink transmissions are performed on the gNB side to simultaneously serve other users (e.g., other UEs), the cell edge terminal (UE) can be assigned to transmit continuously on uplink resources.
[0050] In some embodiments, the gNB (BS) may transmit at least one broadcast signal (e.g., Secondary Synchronization Signal (SSS), Primary Synchronization Signal (PSS), Physical Broadcast Channel (PBCH)) at a specific period. After (e.g., in response to) the UE correctly decoding the information of the broadcast signal, the gNB may transmit downlink transmissions corresponding to a resource configuration set, and / or the UE may transmit uplink transmissions corresponding to a resource configuration set. The resource configuration set may include / be at least one of the following: Control Resource Set 0 (CORESET0), Downlink Initial Bandwidth Part (BWP), Uplink Initial BWP, Downlink BWP, or Uplink BWP. BWP configuration parameters may include a digital scheme, frequency location, frequency band, bandwidth size, or Control Resource Set (CORESET). The Initial Bandwidth Part may be represented by BandwidthPartId = 0. The Initial BWP can be used to perform the initial access procedure.
[0051] At least one of the following configuration methods can be used to protect common channels and / or signals transmitted based on resource configuration sets, as well as common channels and / or signals that cannot be dynamically configured, and can be used to determine new frequency domain adjustment mechanisms.
[0052] Example Method 1
[0053] A base station can schedule resource allocation sets in downlink time slots, uplink time slots, and / or cross-segmented duplex (XDD) time slots. When (e.g., in response to) scheduling a resource allocation set in an XDD time slot, resource elements / faculties of the resource allocation set may overlap with a frequency band of the XDD time slot that has a different transmission direction (sometimes referred to as transmission type) than the resource allocation set. When (e.g., in response to) resource elements / faculties of the resource allocation set overlapping with a frequency band in an XDD time slot that has a different transmission direction than the resource allocation set (transmission direction), the BS can remap (e.g., reschedule, or reallocate / reassign / reconfigure) the frequency-time positions of the resource elements / faculties of the resource allocation set in a defined manner.
[0054] Based on the available resources in the resource configuration set, the BS can remap resource units / elements within the resource configuration set. A resource configuration set can include / is at least one of the following: CORESET0, Downlink Initial BWP, Uplink Initial BWP, Downlink BWP, or Uplink BWP. Resource units / elements can be one of the following: Resource Element (RE), Resource Block (RB), Resource Block Group (RBG), Physical Resource Block (PRB), or Control Channel Element (CCE). A CORESET can be a set of physical resources within a specific area of the downlink resource grid and can be used to carry the PDCCH (DCI). New Radio (NR) PDCCHs are specifically designed for transmission within configurable control resource sets (CORESETs). Frequency allocations in a CORESET configuration can be contiguous or discontinuous. A special CORESET (CORESET0) with index 0 is defined, which can be configured using (e.g., 4-bit) information elements in the Master Information Block (MIB) regarding cell definition synchronization signals and Physical Broadcast Channel (PBCH) blocks (SSBs).
[0055] Now for reference Figure 6 The resource configuration set is CORESET0. CORESET0 can be set / located / scheduled in downlink time slots and XDD time slots. The BS can determine that a portion / part of CORESET0 in the XDD time slot overlaps with the uplink bandwidth, which may prevent the transmission of that portion / part of CORESET0. The BS can determine that the remaining resources of CORESET0 (not overlapping with the uplink bandwidth) are available resource elements / elements. The BS can recombine the available resources in all downlink bandwidths into a complete resource bandwidth, and the BS can remap the control channel element (CCE) of CORESET0 to the downlink bandwidth (available resource elements / elements) in the XDD time slots overlapping with CORESET0. The BS can send a configuration to the UE. This configuration can indicate the resource elements / elements of CORESET0 that overlap with the uplink bandwidth. The resource elements / elements will be remapped by the BS to the downlink bandwidth in the XDD time slots overlapping with CORESET0. In some embodiments, the provided method allows / enables / supports the BS to correctly operate the interleaving mapping and / or the UE to rapidly receive system information block #1.
[0056] Example Method 2
[0057] A base station can schedule resource allocation sets in downlink time slots, uplink time slots, and / or cross-segmented duplex (XDD) time slots. When (e.g., in response to) scheduling a resource allocation set in an XDD time slot, resource elements / elements of the resource allocation set may overlap with a frequency band of the XDD time slot that has a different transmission direction (or type) than the resource allocation set. When (e.g., in response to) resource elements / elements of the resource allocation set overlap with a frequency band in the XDD time slot that has a different transmission direction than the resource allocation set, the base station can remap the resource elements / elements of the resource allocation set in a defined manner.
[0058] When (e.g., in response to) a bandwidth type / transmission direction (e.g., UL or DL) differs from the resource configuration set type / transmission direction (e.g., DL or UL), the base station may perform frequency hopping (e.g., migration, relocation, or rescheduling) on some or all resource elements / elements in the resource configuration set if some or all of the resource elements / elements overlap with the bandwidth. The resource configuration set may include / is at least one of the following: CORESET0, downlink initial BWP, uplink initial BWP, downlink BWP, or uplink BWP. Resource elements / elements may be one of the following: RE, RB, RBG, PRB, or CCE.
[0059] Now for reference Figure 7 The resource configuration set can be CORESET0. CORESET0 can be set / located / scheduled in downlink time slots and XDD time slots. The BS can determine that a portion / part of CORESET0 in the XDD time slot overlaps with the uplink bandwidth, and the uplink bandwidth may not be able to transmit any part of CORESET0. The BS can determine that all control channel elements (CCEs) of CORESET0 that have at least a portion overlapping with the uplink bandwidth can be hopped / migrated (or remapped). Alternatively, the BS can determine that only a portion of the CCEs of CORESET0 that overlaps with the uplink bandwidth can be hopped / migrated. The CCE or a portion of the CCE will be remapped (hopped) to other downlink bandwidth in the XDD time slot. The BS can send a configuration to the UE. This configuration can indicate the resource elements / elements of CORESET0 that overlap with the uplink bandwidth. The resource elements / elements will be remapped (hopped) by the BS to other downlink bandwidth in the XDD time slot. Frequency hopping ensures that CCEs can be mapped to downlink bandwidth to the maximum extent. The provided method allows / enables / supports the BS to properly operate / perform interleaving mapping, and / or the UE to rapidly receive system information block #1.
[0060] Now for reference Figure 8The resource configuration set can be the downlink initial BWP. The downlink initial BWP can be set / located / scheduled in, for example, downlink time slots and XDD time slots. The BS can determine that a portion / part of the downlink initial BWP overlaps with the uplink bandwidth, and the uplink bandwidth may not be able to transmit a portion / any portion of the downlink initial BWP. The BS can determine that all resource blocks (RBs) of the downlink initial BWP having at least a portion overlapping with the uplink bandwidth can be hopped. Alternatively, the BS can determine that only the portion of the RBs of the downlink initial BWP that overlaps with the uplink bandwidth can be hopped (e.g., remapped). The RB or a portion of the RB will be remapped (hopped) to other downlink bandwidth in the XDD time slot. The BS can send a configuration to the UE. This configuration can indicate that resource elements / elements of the downlink initial BWP that overlap with the uplink bandwidth (or all of them having at least a portion overlapping with the uplink bandwidth) will be remapped. The resource elements / elements will be remapped (hopped) by the BS to other downlink bandwidth in the XDD time slot. Frequency hopping ensures that RBs are mapped to downlink bandwidth to the maximum extent possible. The provided method allows / enables / supports the BS to properly operate / perform interleaving mapping, and / or the UE to rapidly receive system information block #1.
[0061] Now for reference Figure 9 The resource configuration set is CORESET0. CORESET0 is set / located / scheduled in the downlink time slot and the XDD time slot. The BS can determine that a portion / part of CORESET0 overlaps with the uplink bandwidth, and the uplink bandwidth may not be able to transmit a portion / any portion of CORESET0. The BS can determine that all control channel elements (CCEs) of CORESET0 can be hopped / migrated (or remapped). The CCEs will be remapped (hopped) to other downlink bandwidths in the XDD time slot. The BS can send a configuration to the UE. This configuration can indicate that resource elements / elements of CORESET0 that overlap with the uplink bandwidth (or all resource elements / elements with at least a portion overlapping with the uplink bandwidth) will be remapped. All resource elements / elements of CORESET0 will be remapped (hopped) by the BS to other downlink bandwidths in the XDD time slot. Frequency hopping can ensure that CCEs are mapped to the downlink bandwidth to the maximum extent. The provided method allows / enables / supports the BS to properly operate / perform interleaving mapping, and / or the UE to quickly receive system information block #1.
[0062] For example, such as Figure 9As shown, the resource configuration set can be the downlink initial BWP. The downlink initial BWP is set / located / scheduled in the downlink time slot and the XDD time slot. The BS can determine that a portion / part of the downlink initial BWP overlaps with the uplink bandwidth, and the uplink bandwidth may not be able to transmit a portion / any portion of the downlink initial BWP. The BS can determine that all resource blocks (RBs) of the downlink initial BWP can be hopped. The RBs will be remapped (hopped) to other downlink bandwidths in the XDD time slot. The BS can send a configuration to the UE. This configuration can indicate that resource elements / elements of the downlink initial BWP that overlap with the uplink bandwidth (or all resource elements / elements that have at least a portion overlapping with the uplink bandwidth) will be remapped. All resource elements / elements of the downlink initial BWP will be remapped (hopped) by the BS to other downlink bandwidths in the XDD time slot. Frequency hopping ensures that RBs are mapped to downlink bandwidth to the maximum extent. The provided method allows / enables / supports the BS to properly (e.g., effectively) operate / perform interleaving mapping, and / or the UE to quickly receive system information block #1.
[0063] Example Method 3
[0064] A base station can schedule resource configuration sets in downlink time slots, uplink time slots, and / or cross-segmented duplex (XDD) time slots. When (e.g., in response to) scheduling a resource configuration set in an XDD time slot, resource elements / elements of the resource configuration set may overlap with a frequency band in the XDD time slot that has a different transmission direction (e.g., downlink or uplink) with respect to the resource configuration set. When (e.g., in response to) resource elements / elements of the resource configuration set overlap with a frequency band in the XDD time slot that has a different transmission direction with respect to the resource configuration set, the base station can remap the resource elements / elements in the resource configuration set in a defined manner.
[0065] In some embodiments, the time-domain symbol of the resource configuration set may be extended. The total number of resource units / elements may not change. The resource configuration set may include / is at least one of the following: CORESET0, downlink initial BWP, uplink initial BWP, downlink BWP, or uplink BWP. Resource units may include one of the following: RE, RB, RBG, PRB, or CCE.
[0066] Now for reference Figure 10The resource configuration set can be CORESET0. CORESET0 can be set / located / scheduled in downlink time slots and XDD time slots. The BS can determine that a portion / part of CORESET0 overlaps with the uplink bandwidth, and the uplink bandwidth may not be able to transmit a portion / any portion of CORESET0. The BS can determine that the overlapping portion / part of the CCE of CORESET0 can be moved to the frequency resource / band (downlink bandwidth) corresponding to the next available time domain symbol (e.g., an extended time domain area adjacent to an unremapped / occupied time domain area). The BS can send a configuration to the UE. This configuration can indicate that the resource elements / elements of CORESET0 that overlap with the uplink bandwidth will be remapped. The overlapping resource elements / elements of CORESET0 will be remapped by the BS to other downlink bandwidths corresponding to the next available time domain symbol in the XDD time slot. The provided method allows / enables / supports the BS to properly operate / perform interleaving mapping, and / or the UE to rapidly receive system information block #1.
[0067] Example Method 4
[0068] A base station can schedule resource allocation sets in downlink time slots, uplink time slots, and / or cross-segmented duplex (XDD) time slots. When (e.g., in response to) scheduling a resource allocation set in an XDD time slot, resource elements / elements of the resource allocation set may overlap with a frequency band in the XDD time slot that has a different transmission direction (e.g., downlink or uplink) with respect to the resource allocation set. When (e.g., in response to) resource elements / elements of the resource allocation set overlap with a frequency band in the XDD time slot that has a different transmission direction with respect to the resource allocation set, the base station can remap the resource elements / elements of the resource allocation set in a defined manner.
[0069] In some embodiments, a resource configuration set can be deferred / delayed / moved to the nearest / next available time slot. The type (transmission direction) of the available time slot can be the same type (e.g., transmission direction) as the resource configuration set. A resource configuration set can include / is at least one of the following: CORESET0, downlink initial BWP, uplink initial BWP, downlink BWP, or uplink BWP. A resource element can include one of the following: RE, RB, RBG, PRB, or CCE. Transmissions based on a resource configuration set can be transmitted within the XDD time slot or not. The BS can remap the resource configuration set to the next available time slot with the same transmission direction as the resource configuration set.
[0070] Now for reference Figure 11The resource configuration set can be CORESET0. CORESET0 can be set / located / scheduled in downlink time slots and XDD time slots. The BS can determine that a portion / part of CORESET0 overlaps with uplink bandwidth, and the uplink bandwidth may not be able to transmit CORESET0. The BS can remap / delay CORESET0 to the nearest / next available downlink time slot. The BS can send a configuration to the UE. This configuration can indicate that the resource elements / elements of CORESET0 that overlap with uplink bandwidth will be remapped. All resource elements / elements of CORESET0 will be remapped (e.g., delayed in time) by the BS to the next available downlink time slot. The provided method allows / enables / supports the BS to increase the number of configurable SS / PBCH blocks (SSBs) and / or improve coverage. The provided method can be applied to legacy UEs (e.g., UEs that do not support XDD time slots) or XDD UEs (e.g., UEs that support XDD time slots).
[0071] Method 5
[0072] A base station can schedule resource allocation sets in downlink time slots, uplink time slots, and / or cross-segmented duplex (XDD) time slots. When (e.g., in response to) scheduling a resource allocation set in an XDD time slot, resource elements / elements of the resource allocation set may overlap with a frequency band in the XDD time slot that has a different transmission direction (e.g., downlink or uplink) with respect to the resource allocation set. When (e.g., in response to) resource elements / elements of the resource allocation set overlap with a frequency band in the XDD time slot that has a different transmission direction with respect to the resource allocation set, the base station can remap the resource elements / elements of the resource allocation set in a defined manner.
[0073] In some embodiments, if a portion or all of a resource unit / element of a resource configuration set overlaps with a bandwidth type (transmission direction) different from that of the resource configuration set, then that portion or all of the resource unit / element may be truncated / discarded / unscheduled / unmapped / unallocated (e.g., not transmitted by the BS or remapped to an area in the XDD time slot). Transmissions based on the resource configuration set can be remapped to the remaining available resource units / elements, and the code rate can be increased / upgraded.
[0074] Regarding the example implementation, see Chapter 2.
[0075] In some embodiments, the gNB (BS) can operate in full-duplex mode, and the UE can operate in half-duplex mode. The gNB (BS) can simultaneously transmit downlink transmissions and receive uplink transmissions. On the other hand, the UE can only transmit uplink transmissions or receive downlink transmissions at any given time.

The gNB (BS) can simultaneously transmit downlink transmissions and receive uplink transmissions. Furthermore, the UE can transmit uplink transmissions and receive downlink transmissions at (the same) time points.
[0077] In one example scenario, within at least one XDD slot, a large portion of the downlink bandwidth of the downlink slot is cut off (e.g., allocated / reserved / configured) to be used as uplink bandwidth (such as...). Figure 4 (As shown).
[0078] In another example scenario, in at least one XDD slot, a large uplink bandwidth of the uplink slot is cut off (e.g., allocated / reserved / configured) to be used as downlink bandwidth (such as...). Figure 5 (As shown).
[0079] In some embodiments, the gNB(BS) can send an indication of the duration and transmission direction (e.g., type) of the XDD time slot to the UE via signaling (e.g., Radio Resource Control (RRC) signaling, System Information Block (SIB) signaling). In some embodiments, the XDD mode is more flexible in the time domain. For example, the gNB(BS) can inform the UE of the bandwidth type (e.g., uplink bandwidth or downlink bandwidth) in the XDD time slot via RRC signaling and / or dynamic signaling. At least one of the following methods can be used to determine and indicate the duration and / or transmission direction / type of the frequency band.
