[0020] In some embodiments, the wireless communication device may determine a parameter B in the UL grant. In some embodiments, parameter B may indicate whether a Physical Uplink Shared Channel (PUSCH) transmission scheduled in the UL grant is based on at least one of a subcarrier spacing or a cyclic prefix of an UL subband, or a subcarrier spacing or a cyclic prefix of an UL Bandwidth Portion (BWP), whether the UL grant itself is based on at least one of a subcarrier spacing or a cyclic prefix of an UL subband, or a subcarrier spacing or a cyclic prefix of a UL BWP, or whether the UL grant itself is based on an UL subband or a UL BWP.

[0031] 1. Mobile communication technology and environment 1 illustrates an exemplary wireless communication network and / or system 100 in which the techniques disclosed herein may be implemented, according to one embodiment of the present disclosure. In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and will be referred to herein as “network 100.” Such exemplary network 100 includes a base station 102 (hereinafter “BS 102,” also referred to as a wireless communication node) and a user equipment device 104 (hereinafter “UE 104,” also referred to as a wireless communication device) that can communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 that overlap a geographic area 101. In FIG. 1, the BS 102 and the UE 104 are contained within the respective geographic boundaries of the cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating in its assigned bandwidth to provide sufficient radio coverage for its intended users.

[0032] For example, the BS 102 may operate with an allocated channel transmission bandwidth to provide sufficient coverage to the UE 104. The BS 102 and the UE 104 may communicate via a downlink radio frame 118 and an uplink radio frame 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, the BS 102 and the UE 104 are generally described herein as non-limiting examples of “communication nodes” capable of practicing the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication in accordance with various embodiments of the present solution.

[0033] 2 shows a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. System 200 may include components and elements configured to support known or conventional operational features that need not be described in detail herein. In one exemplary embodiment, system 200 may be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment, such as wireless communication environment 100 of FIG. 1, as described above.

[0034] The system 200 generally includes a base station 202 (hereinafter “BS 202”) and a user equipment device 204 (hereinafter “UE 204”). The BS 202 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 of which is coupled and interconnected as needed via a data communication bus 220. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled and interconnected as needed via a data communication bus 240. The BS 202 communicates with the UE 204 over a communication channel 250, which may be any wireless channel or other medium suitable for the transmission of data as described herein.

[0035] As will be appreciated by those skilled in the art, system 200 may further include any number of modules other than those shown in FIG. 2 . Those skilled in the art will appreciate that the various exemplary blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may 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 exemplary components, blocks, modules, circuits, and steps are described generally in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein will be able to implement such functionality in a manner suitable for each particular application, but such implementation decisions should not be construed as limiting the scope of the present disclosure.

[0036] According to some embodiments, the UE transceiver 230 may be referred to herein as an “uplink” transceiver 230, including a radio frequency (RF) transmitter and an RF receiver, each comprising circuit components coupled to an antenna 232. Alternatively, a duplexing switch (not shown) may couple the uplink transmitter or receiver to the uplink antenna in a time-duplexed manner. Similarly, according to some embodiments, the BS transceiver 210 may be referred to herein as a “downlink” transceiver 210, including an RF transmitter and an RF receiver, each comprising circuit components coupled to an antenna 212. Alternatively, a downlink duplexing switch may couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplexed manner. The operation of the two transceiver modules 210 and 230 may be coordinated in time such that the downlink transmitter is coupled to the downlink antenna 212 while the uplink receiver circuit components are coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 may be coordinated in time such that the uplink transmitter is coupled to the uplink antenna 232 at the same time that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250. In some embodiments, there is close time synchronization with minimal guard times between changes in duplex direction.

[0037] The UE transceiver 230 and the base station transceiver 210 are configured to communicate over a wireless data communication link 250 and cooperate with a suitably configured RF antenna array 212 / 232 capable of supporting a particular wireless communication protocol and modulation scheme. In some exemplary embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it will be understood that the present disclosure is not necessarily limited in application to a particular standard and associated protocol. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variants thereof.

[0038] According to various embodiments, the BS 202 may be, for example, an evolved Node B (eNB), a serving eNB, a target eNB, a femto station, or a pico station. In some embodiments, the UE 204 may be embodied in various types of user devices, such as a mobile phone, a smartphone, a personal digital assistant (PDA), a tablet, a laptop computer, a wearable computing device, etc. The processor modules 214 and 236 may be implemented or realized using a general-purpose processor, an associative memory, a digital signal processor, an application-specific integrated circuit, a field-programmable gate array, 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 manner, a processor may be realized as a microprocessor, a controller, a microcontroller, a state machine, etc. A 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 in conjunction with a digital signal processor core, or any other such configuration.

[0039] Furthermore, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in firmware, in a software module executed by processor modules 214 and 236, respectively, or in any practical combination thereof. Memory modules 216 and 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may 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 may 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 execution of instructions to be executed by processor modules 210 and 230, respectively. Memory modules 216 and 234 may also each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.

[0040] The network communications module 218 generally represents the hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bidirectional communications between the base station transceiver 210 and other network components and communications nodes configured to communicate with the base station 202. For example, the network communications module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, without limitation, the network communications module 218 provides an 802.3 Ethernet interface to enable the base station transceiver 210 to communicate with conventional Ethernet-based computer networks. In this manner, the network communications module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)). As used herein with respect to a specified operation or function, the terms “configured for,” “configured to,” and conjugations thereof refer to a device, component, circuit, structure, machine, signal, etc. that is physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0041] The Open Systems Interconnection (OSI) model (referred to herein as the "Open Systems Interconnection 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 interconnection and communication with other systems. The model is divided into seven subcomponents or layers, each of which represents a conceptual collection of services provided to its upper and lower layers. The OSI model also defines logical networks and effectively describes computer packet transfers by using different layer protocols. The OSI model may also be referred to as the seven-layer OSI model or seven-layer model. In some embodiments, the first layer may be the physical layer. In some embodiments, the second layer may be the medium access control (MAC) layer. In some embodiments, the third layer may be the radio link control (RLC) layer. In some embodiments, the fourth layer may be the packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be the radio resource control (RRC) layer. In some embodiments, the sixth layer may be a non-access stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer is some other layer.

[0042] 2. Systems and methods for configuring uplink transmissions For time division duplex (TDD) carriers, downlink (DL) slots and uplink (UL) slots may be configured in a time division manner. Furthermore, in a particular deployed network, DL slots may be configured with more DL slots than UL slots. For example, the slot structure may be DDDSU. Here, D may represent DL slots, U may represent UL slots, and S may represent flexible slots that may encompass DL and UL symbols. UL slots may be less contiguous, and these characteristics may affect the performance of UL transmissions. For example, large amounts of UL data may not be supported, but more importantly, the timeliness and edge coverage of UL transmissions may be relatively poor (e.g., due to a lack of contiguous UL slots).

[0043] Therefore, a technique for subband full duplex (SBFD) is presented herein. UL subband full duplex may be preferred. For example, several consecutive resource blocks (RBs) may be configured as UL subbands in the frequency domain, and several DL or flexible orthogonal frequency division multiplexing OFDM symbols or slots may be configured as UL subbands in the time domain, resulting in one UL subband. That is, the time-frequency resource for UL transmission may be configured in a DL symbol or slot, and this time-frequency resource may be a UL subband. Based on the UL subband, UL transmission may be performed in a DL symbol or slot. The UL subband may also be configured in a flexible symbol.

[0044] This specification presents a UL subband configuration architecture for achieving efficient transmission based on the full-duplex mechanism of the UL subband. Additionally, this disclosure provides corresponding UL subband parameter configuration, including how to configure parameters related to uplink signal or channel resources and symbol attributes. Furthermore, this disclosure provides how to determine UL transmission parameters when different UL subbands are configured with different parameters, and also how to determine UL transmission parameters when UL subbands and UL / DL bandwidth portions (BWPs) may be configured with different parameters. Herein, a symbol or slot configured in a UL subband may be referred to as an SBFD symbol or slot, and a symbol or slot not configured in a UL subband may be referred to as a non-SBFD symbol or slot.

[0045] A. Cell-specific Uplink (UL) Subband Resource Configuration I. UL Subband Configuration Architecture The base station and the UE may agree that only the cell-specific UL subband resources may be configured, and the UE-specific UL subband resources may not be configured. For some specific configurations, see Table 1.

[0046] [Table 1]

[0047] For convenience of the following description, a candidate resource set for an uplink channel / signal may be referred to as resource set C, and the subcarrier spacing (SCS) and / or cyclic prefix (CP) may be referred to as symbol attribute parameters.

[0048] Resources for the cell-specific UL subband may be configured by the base station based on point-to-multipoint signaling to the UE. That is, all UEs in a cell may receive the same signaling to configure the cell-specific UL subband. From the base station side, only one cell-specific UL subband may be configured in a cell. The resources of the cell-specific UL subband may be contiguous in the frequency domain.

[0049] Corresponding to index 0 in Table 1, only the cell-specific UL subband may be configured with the corresponding resource, the symbol attribute parameter of the cell-specific UL subband may not be configured, and the resource set C corresponding to the cell-specific UL subband may not be configured.

[0050] Corresponding to index 1 in Table 1, the cell-specific UL subband may be configured with the corresponding resource, and the symbol attribute parameters of the cell-specific UL subband may also be configured, but the resource set C corresponding to the cell-specific UL subband may not be configured.

[0051] Corresponding to index 2 in Table 1, the cell-specific UL subband may be configured with the corresponding resource, and the resource set C corresponding to the cell-specific UL subband may also be configured, but the symbol attribute parameters of the cell-specific UL subband may not be configured.

[0052] Corresponding to index 3 in Table 1, a cell-specific UL subband may be configured with corresponding resources, resource set C, and symbol attribute parameters.

[0053] For a UE, the cell-specific UL subband resources may intersect with its UL BWP resources at least in the frequency domain, and UL transmissions may be scheduled or configured on the intersected resources within an SBFD symbol. The cell-specific UL subband resources may include time-domain and / or frequency-domain resources.

[0054] The candidate resource sets for uplink channels / signals corresponding to the above cell-specific UL subbands may include, among others, a physical uplink shared channel (PUSCH) candidate resource set (including k2, where k2 may be the slot interval between a slot in which an UL grant may be placed and a slot in which a corresponding PUSCH transmission may be placed), a physical uplink control channel (PUCCH) resource set (including k1, where k1 may be the slot interval between a slot in which a physical downlink shared channel (PDSCH) may be placed and a slot in which a corresponding hybrid automatic repeat request-acknowledgement (HARQ-ACK) PUCCH transmission may be placed), a physical random access channel (PRACH) resource, or a sounding reference signal (SRS) resource.

[0055] The point-to-multipoint signaling may include a system information block, a group physical downlink control channel (PDCCH), and a UE-dedicated radio resource control (RRC) signaling. For example, the PUSCH candidate resource set may be configured based on the signaling PUSCH-Config according to a specification (e.g., in TS38.331), and the PUCCH resource set may be configured based on the signaling PUCCH-Config.

[0056] If an UL transmission is scheduled or configured on resources of a cell-specific UL subband, the UL transmission may be performed based on the symbol attribute parameters of the cell-specific UL subband and resources selected from resource set C of the cell-specific UL subband.

[0057] However, if the symbol attribute parameters of a cell-specific UL subband are configured and UL transmissions of different UEs are scheduled or configured on the resources of the cell-specific UL subband, these UL transmissions may use only the unique symbol attribute parameters of the cell-specific UL subband for all UEs in the cell. This may cause some adverse effects. For example, because the locations and channel qualities of different UEs in a cell may differ, different SCSs or CPs for UL transmissions may result in higher efficiency from the perspective of different UEs. For example, UEs located at the edge of a cell may prefer a longer CP to eliminate interference between adjacent symbols.

[0058] Similarly, if a cell-specific UL subband resource set C is configured and UL transmissions of different UEs are scheduled or configured on resources of the cell-specific UL subband, these UL transmissions may use only the cell-specific UL subband resource set C for all UEs in the cell. From the perspective of different UEs, it may lack flexibility in the selection of uplink channel / signal resources. II. Improvements to determining resource set C and / or symbol attribute parameters for UL transmission within resources of a cell-specific UL subband.

[0059] If an UL transmission is scheduled or configured (e.g., by a BS to the UE) in resources of a cell-specific UL subband for the UE, and resource set C of the cell-specific UL subband and symbol attribute parameters of the cell-specific UL subband are not configured, the base station and the UE may agree that the UL transmission is performed based on resource set C of the UE's UL BWP and symbol attribute parameters of the UL BWP. If, from the UE's perspective, resource set C of the cell-specific UL subband may not be configured, the base station and the UE may agree that the cell-specific UL subband may use resource set C of the UE's UL BWP. If symbol attribute parameters of the cell-specific UL subband are not configured, the base station and UE may agree that the cell-specific UL subband may use symbol attribute parameters of the UE's UL BWP.

[0060] In some embodiments, if the resource set C of the cell-specific UL subband and / or the symbol attribute parameters of the cell-specific UL subband are not configured, the base station and the UE may agree that the UL transmission will be performed based on the resource set C of the UE's initial BWP and / or based on the symbol attribute parameters of the UE's initial BWP.

[0061] III. Use of Cell-Specific UL Subband Resource Set C and Symbol Attribute Parameters In some embodiments, when a cell-specific UL subband resource set C and / or symbol attribute parameters are configured, and when an UL transmission is scheduled or configured in the cell-specific UL subband resources for the UE, the base station and the UE may agree on the following: UL transmission should be performed based on the symbol attribute parameters of the UE's UL BWP and / or resource set C. This may be a relatively simple method, but may not be flexible enough. Alternatively, the base station may indicate by signaling the symbol attribute parameters and / or resource set C to be used for this UL transmission. For example, the signaling may indicate that the symbol attribute parameters or resource set C of the UL BWP may be used for the UL transmission. In another example, the signaling may indicate that the symbol attribute parameters or resource set C of the cell-specific UL subband may be used for the UL transmission. This may be a more efficient method, which may flexibly change the symbol attribute parameters or resource set C used by the UL transmission according to scheduling requirements. For example, a UE located at the cell edge may be more suitable to use a longer CP and a larger SCS.

[0062] In some embodiments, if a cell-specific UL subband resource set C and / or a cell-specific UL subband symbol attribute transmission is configured, and if an initial access-related UL transmission is scheduled or configured for the UE in the cell-specific UL subband resources, the UL transmission may be performed based on the cell-specific UL subband symbol attribute parameters and / or the resource set C. Here, the initial access-related UL transmission may include a transmission of an initial access sequence, a PUSCH transmission scheduled by a random access response (RAR), and a HARQ-ACK PUCCH transmission in the random access process.

[0063] In some embodiments, if a cell-specific UL subband resource set C and / or a cell-specific UL subband symbol attribute transmission is configured, and if a common UL transmission is scheduled or configured on the cell-specific UL subband resources for the UE, the UL transmission may be performed based on the cell-specific UL subband symbol attribute parameters and / or resource set C.

[0064] IV. Improvement based on the symbol type (DL symbol or F symbol) of the symbol in which the UL subband is located. In some embodiments, if the symbol attribute parameters of the cell-specific UL subband are not configured, and if an UL transmission is scheduled or configured in the resources of the cell-specific UL subband for the UE, the UL transmission may be performed based on the symbol attribute parameters of the DL BWP of the UE.

[0065] In some embodiments, if a cell-specific UL subband is configured in a DL symbol or slot, and if an UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband are configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP.

[0066] In some embodiments, if the cell-specific UL subband is configured in flexible symbols or slots, and if UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP.

[0067] In some embodiments, if the cell-specific UL subband is configured in DL symbols or slots converted from flexible symbols or slots, and if UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband are configured), the UL transmission may be performed based on the symbol attribute parameters of the DL BWP of the UE. In some embodiments, the UL transmission is performed based on the symbol attribute parameters of the UL BWP of the UE.

[0068] In some embodiments, if a cell-specific UL subband is configured in a DL symbol or slot, and if an UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the DL symbol. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UL symbol.

[0069] In some embodiments, if a cell-specific UL subband is configured in a flexible symbol or slot, and if an UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband are configured), the UL transmission may be performed based on the symbol attribute parameters of the flexible symbol.

[0070] In some embodiments, if a cell-specific UL subband is configured in a DL symbol or slot converted from a flexible symbol or slot, and if an UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the DL symbol. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UL symbol.

[0071] In some embodiments, the base station and the UE agree that the symbol attribute parameters of the cell-specific UL subband are by default the same as the symbol attribute parameters of the symbols of the cell-specific UL subband. In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the cell-specific UL subband are by default the same as those of the UL BWP. In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the cell-specific UL subband are by default the same as those of the DL BWP.

[0072] B. UE-specific uplink (UL) subband resource configuration I. UL Subband Configuration Architecture The base station and the UE may agree that only the resources of the UE-specific UL subband may be configured, and the resources of the cell-specific UL subband may not be configured. For some specific configurations, see Table 2.

[0073] [Table 2]

[0074] Note: A "1" may indicate that the corresponding item is configured, and a "0" may indicate that the corresponding item may not be configured.

[0075] For convenience of the following description, a candidate resource set for an uplink channel / signal may be referred to as resource set C, and the SCS and / or CP may be referred to as symbol attribute parameters.

[0076] Resources for UE-specific UL subbands can be configured by the base station based on point-to-point signaling to the UE. That is, different UEs in a cell can be configured with UE-specific UL subbands. However, from the base station's perspective, it may be better for the UL subbands of different UEs to be in a contiguous frequency range. In this way, the base station can always receive UL subbands of different UEs in a contiguous frequency range. To reduce costs, it may be beneficial for the base station to lock the frequency domain resource range for reception.

[0077] Corresponding to index 0 in Table 2, the UE-specific UL subband only needs to be configured with the corresponding resource, the symbol attribute parameter of the UE-specific UL subband may not be configured, and the resource set C corresponding to the UE-specific UL subband may not be configured.

[0078] Corresponding to index 1 in Table 2, the UE-specific UL subband may be configured with the corresponding resource, and the symbol attribute parameters of the UE-specific UL subband may also be configured, but the resource set C corresponding to the UE-specific UL subband may not be configured.

[0079] Corresponding to index 2 in Table 2, the UE-specific UL subband may be configured with the corresponding resource, and the resource set C corresponding to the UE-specific UL subband may also be configured, but the symbol attribute parameter of the UE-specific UL subband may not be configured.

[0080] Corresponding to index 3 in Table 2, a UE-specific UL subband may be configured with corresponding resources, resource set C, and symbol attribute parameters.

[0081] For a UE, the resources of the UE-specific UL subband may intersect with its UL BWP resources at least in the frequency domain, and UL transmissions may be scheduled or configured on the intersected resources within the SBFD symbol. The above-mentioned UE-specific UL subband resources may include time-domain resources and / or frequency-domain resources.

[0082] The candidate resource set for an uplink channel or signal may correspond to the above-mentioned UE-specific UL subband, including a PUSCH candidate resource set (including k2, where k2 may be the slot interval between a slot in which an UL grant may be placed and a slot in which a corresponding PUSCH transmission may be placed), a PUCCH resource set (including k1, where k1 may be the slot interval between a slot in which a PDSCH may be placed and a slot in which a corresponding HARQ-ACK PUCCH transmission may be placed), a PRACH resource, or an SRS resource.

[0083] The point-to-multipoint signaling may include a system information block (SIB) and a group PDCCH. The point-to-point signaling may include PDCCH signaling and UE-dedicated RRC signaling. For example, the PUSCH candidate resource set may be configured based on the PUSCH-Config signaling according to a specification (e.g., TS38.331), and the PUCCH resource set may be configured based on the PUCCH-Config signaling.

[0084] If an UL transmission is scheduled or configured on resources of the UE-specific UL subband, the UL transmission may be performed based on the symbol attribute parameters of the UE-specific UL subband and resources selected from resource set C of the UE-specific UL subband.

[0085] II. Improvements to determining resource set C and / or symbol attribute parameters for UL transmission within resources of a UE-specific UL subband. When an UL transmission is scheduled or configured in resources of a UE-specific UL subband for a UE, and resource set C of the UE-specific UL subband and symbol attribute parameters of the UE-specific UL subband are not configured, the base station and the UE may agree that the UL transmission should be performed based on resource set C of the UE's UL BWP and symbol attribute parameters of the UL BWP. That is, from the UE's perspective, when resource set C of the UE-specific UL subband is not configured, the base station and the UE may agree that the UE-specific UL subband uses resource set C of the UE's UL BWP. When symbol attribute parameters of the UE-specific UL subband may not be configured, the base station and the UE may agree that the UE-specific UL subband uses symbol attribute parameters of the UE's UL BWP.

[0086] In some embodiments, when the resource set C of the UE-specific UL subband and / or the symbol attribute parameters of the UE-specific UL subband may not be configured, the base station and the UE may agree that the UL transmission will be performed based on the resource set C of the UE's initial BWP and / or based on the symbol attribute parameters of the UE's initial BWP.

[0087] III. UE-Specific UL Subband Resource Set C and Symbol Attribute Parameter Usage In some embodiments, when a resource set C and / or symbol attribute parameters of a UE-specific UL subband are configured, and when an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE, the base station and the UE may agree on the following: UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP and / or resource set C. This may be a relatively simple method, but may not be flexible enough. Alternatively, the base station may indicate by signaling the symbol attribute parameters and / or resource set C to be used for this UL transmission. For example, the signaling may indicate that the symbol attribute parameters or resource set C of the UL BWP may be used for UL transmission. For example, the signaling may indicate that the symbol attribute parameters or resource set C of the UE-specific UL subband may be used for UL transmission. This may be an efficient method, which may flexibly change the symbol attribute parameters and / or resource set C used by the UL transmission according to scheduling requirements. For example, a UE located at the cell edge may be more suitable to use a longer CP and a larger SCS.

[0088] Alternatively, if a resource set C of a UE-specific UL subband and / or a symbol attribute transmission of the UE-specific UL subband are configured, and if an UL transmission related to initial access (e.g., non-contention initial access) is scheduled or configured for the UE in resources of the UE-specific UL subband, the UL transmission may be performed based on the symbol attribute parameters of the UE-specific UL subband and / or the resource set C. Here, the UL transmission related to initial access may include transmission of an initial access sequence, a PUSCH transmission scheduled by RAR, and a HARQ-ACK PUCCH transmission in a random access process.

[0089] IV. Improvement based on the symbol type (DL symbol or F symbol) of the symbol in which the UL subband is located. In some embodiments, if the symbol attribute parameters of the UE-specific UL subband are not configured, and if an UL transmission is scheduled or configured in the resources of the UE-specific UL subband for the UE, the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP.

[0090] In some embodiments, if a UE-specific UL subband is configured in a DL symbol or slot, and if an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the UE-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP.

[0091] In some embodiments, if a UE-specific UL subband is configured in flexible symbols or slots, and if an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the UE-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP.

[0092] In some embodiments, if a UE-specific UL subband is configured in DL symbols or slots converted from flexible symbols or slots, and if an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the UE-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP.

[0093] In some embodiments, if a UE-specific UL subband is configured in a DL symbol or slot, and if an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the UE-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the DL symbol. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UL symbol).

[0094] In some embodiments, if a UE-specific UL subband is configured in a flexible symbol or slot, and if an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the UE-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the flexible symbol. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UL symbol.

[0095] In some embodiments, if a UE-specific UL subband is configured in a DL symbol or slot converted from a flexible symbol or slot, and if an UL transmission is scheduled or configured in resources of the UE-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the UE-specific UL subband may be configured), the UL transmission may be performed based on the symbol attribute parameters of the DL symbol. In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UL symbol.

In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the UE-specific UL subband are by default the same as that of the UL BWP. In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the UE-specific UL subband are by default the same as that of the DL BWP.

[0097] C. Cell-Specific and UE-Specific Resource Configuration for Uplink (UL) Subbands I. UL Subband Configuration Architecture The base station and the UE may agree that the cell-specific UL subband resources are configured and that the UE-specific UL subband resources may also be configured. For some specific configurations, see Table 3-1.

[0098] [Table 3-1]

[0099] For convenience of the following description, a candidate resource set for an uplink channel or signal may be referred to as resource set C, and SCS or CP may be referred to as a symbol attribute parameter.

[0100] The resources for the cell-specific UL subband may be configured by the base station based on point-to-multipoint signaling to the UE. That is, all UEs in a cell may receive the same signaling to configure the cell-specific UL subband. That is, from the base station side, only one cell-specific UL subband may be configured in a cell. The resources of the cell-specific UL subband may be contiguous in the frequency domain.

[0101] Resources for UE-specific UL subbands can be configured by the base station based on point-to-point signaling to the UE. That is, different UEs in a cell can be configured with UE-specific UL subbands. However, from the base station's perspective, it may be better if the UL subbands of different UEs can be in a contiguous frequency range. In this way, the base station can always receive UL subbands of different UEs in a contiguous frequency range. To reduce costs, it may be beneficial for the base station to lock the frequency domain resource range of reception.

[0111] Corresponding to index 9 in Table 3-1, a cell-specific UL subband may be configured with corresponding resources, and the symbol attribute parameters of the cell-specific UL subband may also be configured, but the resource set C corresponding to the cell-specific UL subband may not be configured; a UE-specific UL subband may be configured with corresponding resources, and the resource set C corresponding to the UE-specific UL subband may also be configured, but the symbol attribute parameters of the UE-specific UL subband may not be configured.

[0113] Corresponding to index 11 in Table 3-1, a cell-specific UL subband may be configured with corresponding resources, a resource set C, and symbol attribute parameters. A UE-specific UL subband may be configured with corresponding resources, and a resource set C corresponding to the UE-specific UL subband may also be configured, but the symbol attribute parameters of the UE-specific UL subband may not be configured.

[0114] Corresponding to index 12 in Table 3-1, a cell-specific UL subband may only be configured with corresponding resources, the symbol attribute parameters of the cell-specific UL subband may not be configured, and the resource set C corresponding to the cell-specific UL subband may not be configured. A UE-specific UL subband may be configured with corresponding resources, resource set C, and symbol attribute parameters.

[0115] Corresponding to index 13 in Table 3-1, the cell-specific UL subband may be configured with the corresponding resource, and the symbol attribute parameters of the cell-specific UL subband may also be configured, but the resource set C corresponding to the cell-specific UL subband may not be configured, and the UE-specific UL subband may be configured with the corresponding resource, resource set C, and symbol attribute parameters.

[0118] In the above Table 3-1, the best configuration may include that the cell-specific UL subband may be configured only as a time-frequency resource, and may not be configured with symbol attribute parameters and resource set C. However, the UE-specific UL subband may be configured with time-frequency resources and may also be configured with symbol attribute parameters and / or resource set C. These configurations may be well suited for UE-specific UL transmission based on the symbol attribute parameters and / or resource set C of the UE-specific UL subband.

[0119] For a UE, the cell-specific UL subband resources, the UE-specific UL subband resources, and the UL BWP resources at least intersect in the frequency domain, and UL transmissions may be scheduled or configured on the intersected resources. UE-dedicated UL transmissions should be scheduled or configured on the intersected resources. For a UE, common UL transmissions may be scheduled or configured on the intersected resources. Common UL transmissions may also be scheduled or configured on the cell-specific UL subband resources in addition to the UE-specific UL subband resources and UL BWP resources.

[0120] The resource of the above UE-specific UL subband includes time domain resources and / or frequency domain resources. The candidate resource set of the uplink channel / signal corresponding to the above UE-specific UL subband includes a PUSCH candidate resource set (including k2, where k2 is a slot interval between a slot in which an UL grant may be placed and a slot in which a corresponding PUSCH transmission may be placed), a PUCCH resource set (including k1, where k1 may be a slot interval between a slot in which a PDSCH may be placed and a slot in which a corresponding HARQ-ACK PUCCH transmission may be placed), a PRACH resource, or an SRS resource.

[0121] The above point-to-multipoint signaling includes a system information block (SIB) and a group PDCCH.

For example, the PUSCH candidate resource set may be configured based on the signaling PUSCH-Config in accordance with a specification (e.g., TS38.331), and the PUCCH resource set may be configured based on the signaling PUCCH-Config.

[0122] II. Improvements to determining resource set C or symbol attribute parameters for UL transmission within resources of the UL subband. When an UL transmission is scheduled or configured in resources of a cell-specific UL subband for a UE, and resource set C of the cell-specific UL subband and symbol attribute parameters of the cell-specific UL subband are not configured, the base station and the UE may agree that the UL transmission will be performed based on resource set C of the UE's UL BWP and symbol attribute parameters of the UL BWP. That is, from the UE's perspective, when resource set C of the cell-specific UL subband is not configured, the base station and the UE may agree that the cell-specific UL subband will use resource set C of the UE's UL BWP. When symbol attribute parameters of the cell-specific UL subband are not configured, the base station and UE may agree that the cell-specific UL subband will use symbol attribute parameters of the UE's UL BWP.

[0123] When an UL transmission is scheduled or configured in resources of a UE-specific UL subband for a UE, and resource set C of the UE-specific UL subband and symbol attribute parameters of the UE-specific UL subband are not configured, the base station and the UE may agree that the UL transmission is performed based on resource set C of the UE's UL BWP and symbol attribute parameters of the UL BWP. From the UE's perspective, if resource set C of the UE-specific UL subband is not configured, the base station and the UE may agree that the UE-specific UL subband uses resource set C of the UE's UL BWP. If symbol attribute parameters of the UE-specific UL subband are not configured, the base station and UE may agree that the UE-specific UL subband uses symbol attribute parameters of the UE's UL BWP.

[0124] In some embodiments, if resource set C of a cell-specific UL subband and / or symbol attribute parameters of the cell-specific UL subband are not configured, the base station and the UE may agree that UL transmission will be performed based on resource set C of the UE's initial BWP and / or based on symbol attribute parameters of the UE's initial BWP. In some embodiments, if resource set C of a UE-specific UL subband and / or symbol attribute parameters of the UE's initial BWP are not configured, the base station and UE may agree that UL transmission will be performed based on resource set C of the UE's initial BWP and / or based on symbol attribute parameters of the UE's initial BWP.

[0125] In some embodiments, if a resource set C and / or symbol attribute parameters of a cell-specific UL subband are configured, and if a resource set C and / or symbol attribute parameters of a UE-specific UL subband are configured, and if an UL transmission is scheduled or configured in resources of the UL subband for the UE, the base station and the UE may agree that an UL transmission should be scheduled or configured in the intersection resources of the cell-specific UL subband, the UE-specific UL subband, and the UE's UL BWP resources.

[0126] In addition, the base station and the UE agree to the following: ·UL transmission is performed based on UE-specific UL subband symbol attribute parameters and / or resource set C. Alternatively, the UL transmission is performed based on the symbol attribute parameters of the UE's BWP and / or the resource set C. Alternatively, the base station may indicate by signaling the symbol attribute parameters and / or resource set C to be used for this UL transmission. For example, the signaling may indicate that the symbol attribute parameters and / or resource set C of the UL BWP are used for the UL transmission. For example, the signaling may indicate that the symbol attribute parameters and / or resource set C of the UE-specific UL subband are used for the UL transmission. For example, the signaling may indicate that the symbol attribute parameters and / or resource set C of the cell-specific UL subband may be used for the UL transmission.

[0127] III. Determination and use of resource set C and symbol attribute parameters for the UL subband. In some embodiments, the base station and the UE agree to determine the symbol attribute parameters and / or resource set C used by the UL transmission according to the transmission type of the scheduled UL transmission. The symbol attribute parameters and / or resource set C may be determined from the symbol attribute parameters and / or resource set C of the cell-specific UL subband, the UE-specific UL subband, the UL BWP, or the DL BWP. The transmission type of the UL transmission may include a UE-dedicated UL transmission, a public UL transmission, a UL transmission after random access, and a UL transmission during random access.

[0128] In some embodiments, the base station and the UE agree to determine the symbol attribute parameters used by the UL transmission according to the resource location of the UL transmission. The symbol attribute parameters may be determined from the symbol attribute parameters of the cell-specific UL subband, the UE-specific UL subband, or the UL BWP. The resource location of the UL transmission includes the UL transmission being located in the resources of the cell-specific UL subband but not in the resources of the UE-specific UL subband, and the UL transmission being located in the resources of the UE-specific UL subband. If the UL transmission is within the resources of the cell-specific UL subband but not in the resources of the UE-specific UL subband, the UL transmission may be performed based on the symbol attribute parameters of the cell-specific UL subband. If the UL transmission is within the resources of the UE-specific UL subband, the UL transmission may be performed based on the symbol attribute parameters of the UE-specific UL subband or the UL BWP.

[0129] In some embodiments, if a cell-specific UL subband resource set C and / or a cell-specific UL subband symbol attribute transmission is configured, and if an initial access-related UL transmission is scheduled or configured for the UE in the cell-specific UL subband resources, the UL transmission may be performed based on the cell-specific UL subband symbol attribute parameters and / or the resource set C. Here, the initial access-related UL transmission may include a transmission of an initial access sequence, a PUSCH transmission scheduled by the RAR, and a HARQ-ACK PUCCH transmission in the random access process.

[0130] In some embodiments, if a cell-specific UL subband resource set C and / or a cell-specific UL subband symbol attribute transmission is configured, and if a common UL transmission is scheduled or configured on the cell-specific UL subband resources for the UE, the UL transmission may be performed based on the cell-specific UL subband symbol attribute parameters and / or resource set C.

[0131] In some embodiments, if a resource set C of a UE-specific UL subband and / or a symbol attribute transmission of the UE-specific UL subband are configured, and if an UL transmission related to initial access (e.g., non-contention initial access) may be scheduled or configured for the UE in resources of the UE-specific UL subband, the UL transmission may be performed based on the symbol attribute parameters of the UE-specific UL subband and / or the resource set C. Here, the UL transmission related to initial access includes transmission of an initial access sequence, a PUSCH transmission scheduled by RAR, and a HARQ-ACK PUCCH transmission in a random access process.

[0132] IV. Improvement based on the symbol type (DL symbol or F symbol) of the symbol in which the UL subband is located. In some embodiments, if the symbol attribute parameters of the cell-specific UL subband are not configured, and if UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE, the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP (or UL BWP). In some embodiments, the UL transmission is performed based on the symbol attribute parameters of the UE-specific UL subband symbol attribute parameters (if configured).

[0133] In some embodiments, if a cell-specific UL subband is configured in a DL symbol or slot, and if UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband are configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP (or UL BWP). In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE-specific UL subband's symbol attribute parameters (if configured), or the UL transmission may be performed based on the symbol attribute parameters of the DL (or UL) symbol.

[0134] In some embodiments, if a cell-specific UL subband is configured in a flexible symbol or slot, and if UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband are configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's UL BWP (or DL ​​BWP). In some embodiments, the UL transmission is performed based on the symbol attribute parameters of the UE-specific UL subband's symbol attribute parameters (if configured), or the UL transmission is performed based on the symbol attribute parameters of the flexible (or UL) symbol.

[0135] In some embodiments, if a cell-specific UL subband is configured in DL symbols or slots converted from flexible symbols or slots, and if UL transmission is scheduled or configured in resources of the cell-specific UL subband for the UE (regardless of whether the symbol attribute parameters of the cell-specific UL subband are configured), the UL transmission may be performed based on the symbol attribute parameters of the UE's DL BWP (or UL BWP). In some embodiments, the UL transmission may be performed based on the symbol attribute parameters of the UE-specific UL subband's symbol attribute parameters (if configured), or the UL transmission may be performed based on the symbol attribute parameters of the DL (or UL) symbols.

[0136] In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the UE-specific UL subbands and cell-specific UL subbands are by default the same as the symbol attribute parameters of the symbols of the UE-specific UL subbands. In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the UE-specific UL subbands and cell-specific UL subbands are by default the same as that of the UL BWP. In some embodiments, the base station and the UE may agree that the symbol attribute parameters of the UE-specific UL subbands and cell-specific UL subbands are by default the same as that of the DL BWP.

[0137] V. Using Frequency Domain Resource Intersection for UL Subbands In addition, if the resources of the cell-specific UL subband are configured but the resources of the UE-specific UL subband are not configured, the frequency domain resources of the UE-specific UL subband may be the intersection of the frequency domain resources of the cell-specific UL subband and the frequency domain resources of the UL BWP or initial BWP by default. The time domain resources of the UE-specific UL subband may be the same as those of the cell-specific UL subband. The resource set C and symbol attribute parameters of the UE-specific UL subband may be configured. Table 3-2 may be referenced.

[0138] Table 3-2 provides a configuration method for a cell-specific UL subband and a UE-specific UL subband. In Table 3-2, the resource set C or symbol attribute parameter corresponding to the UE-specific UL subband may be configured, but the corresponding resource may not be configured.

[0139] For example, at index 0 in Table 3-2, only resources of the cell-specific UL subband are configured. UL transmissions may be scheduled or configured only in the intersection resources of the frequency domain resources of the cell-specific UL subband and the frequency domain resources of the UL BWP (or initial UL BWP). UL transmissions may be performed based on the resource set C and / or symbol attribute parameters of the UL BWP (or initial BWP).

[0140] For index 12 in Table 3-2, resources of the cell-specific UL subband may be configured, but the corresponding resource set C and symbol attribute parameters may not be configured. Resources of the UE-specific UL subband may not be configured, but the corresponding resource set C and symbol attribute parameters may be configured. UL transmissions may be scheduled or configured only at the intersection of the frequency domain resources of the cell-specific UL subband and the frequency domain resources of the UL BWP (or initial UL BWP). UL transmissions are performed based on the resource set C and symbol attribute parameters of the UE-specific UL subband.

[0141] Based on the configurations of the cell-specific UL subbands and UE-specific UL subbands provided in Table 3-2, the methods of the above embodiments can be reused for the configurations of each row.

[0142] [Table 3-2]

[0143] D. Physical Uplink Shared Channel (PUSCH) Candidate Resource Set Configuration In the subband full-duplex technology, the PUSCH candidate resource sets may be configured for SBFD slots and non-SBFD slots, respectively, but the present application believes that the above method has the following problems.

[0144] I. Problem Description The following Table 4 may be PUSCH candidate resource sets configured for SBFD slots by signaling PUSCH-config according to a specification (e.g., TS38.331). Additionally, the following Table 5 may be PUSCH candidate resource sets configured for non-SBFD slots by signaling PUSCH-config.

[0145] When a UE receives downlink control information (DCI) (also referred to as an UL grant) from a PDCCH to schedule a PUSCH transmission, the UE cannot determine whether the PUSCH resource allocation indicator in the UL grant (e.g., a row index of a PUSCH candidate resource set) is to be understood based on Table 4 or Table 5. If the position of a slot transmitting a PUSCH transmission can be determined based on the UL grant, it may be easy to think that the type of slot (e.g., an SBFD slot or a non-SBFD slot) can be determined based on the configuration pattern of the SBFD slot. In this way, since Table 4 is associated with SBFD slots and Table 5 is associated with non-SBFD slots, the PUSCH resource allocation indicator can also be correctly understood based on the type of slot.

[0146] However, in the PUSCH candidate resource set, each PUSCH resource may be associated with a parameter k2, which may describe the slot interval between the slot in which the UL grant may be located and the slot in which the PUSCH transmission may be located. Thus, the PUSCH resource allocation indicator may indicate not only the PUSCH resource corresponding to the PUSCH transmission, but also the slot position corresponding to the PUSCH transmission. Therefore, the slot position of the PUSCH transmission cannot be determined before the understanding of the PUSCH resource allocation indicator can be determined.

[0147] For example, the value of the PUSCH resource allocation indicator is 0, i.e., index 0, but the UE cannot determine whether index 0 can be understood based on Table 4 or Table 5, so the UE cannot determine the PUSCH resource corresponding to the PUSCH transmission and the slot position corresponding to the PUSCH transmission.

[0148] [Table 4]

[0149] [Table 5]

[0150] The following solutions are provided to the above problems.

[0151] II. Method 1 A new parameter A may be added to the UL grant, which may be used to indicate whether the PUSCH resource allocation indicator in the UL grant may be based on the PUSCH candidate resource set configured for the SBFD slot or the PUSCH candidate resource set configured for the non-SBFD slot.

[0152] In some embodiments, parameter A may be used to indicate that the UL grant itself may be based on a PUSCH candidate resource set configured for an SBFD slot or may be based on a PUSCH candidate resource set configured for a non-SBFD slot.

[0153] In some embodiments, parameter A may be used to indicate whether the UL grant itself may be based on an SBFD slot (and corresponding configuration associated with the SBFD slot) or a non-SBFD slot (and corresponding configuration associated with the non-SBFD slot).

[0154] The base station indicates whether the UL grant may be based on an SBFD slot (and the corresponding configuration associated with the SBFD slot) or a non-SBFD slot (and the corresponding configuration associated with the non-SBFD slot) by setting the value of parameter A. The UE also determines whether the UL grant may be based on an SBFD slot (and the corresponding configuration associated with the SBFD slot) or a non-SBFD slot (and the corresponding configuration associated with the non-SBFD slot) according to the value of parameter A in the UL grant.

[0155] III. Method 2 A new parameter B may be added to the UL grant. Parameter B may be used to indicate whether a PUSCH transmission scheduled in the UL grant may be based on the SCS and / or CP of the UL subband or the SCS and / or CP of the UL BWP. The base station and the UE may also agree that if parameter B indicates that the PUSCH transmission is based on the SCS and / or CP of the UL subband, the PUSCH resource allocation indicator corresponding to the PUSCH transmission may also be based on the PUSCH candidate resource set of the UL subband (e.g., based on the PUSCH candidate resource set configured for the SBFD slot). If parameter B indicates that the PUSCH transmission is based on the SCS and / or CP of the UL BWP, the PUSCH resource allocation indicator corresponding to the PUSCH transmission may be based on the PUSCH candidate resource set of the UL BWP (e.g., based on the PUSCH candidate resource set configured for the non-SBFD slot).

[0156] In some embodiments, parameter B may be used to indicate the UL grant itself on the SCS and / or CP of the UL subband, or based on the SCS and / or CP of the UL BWP. The base station and UE may also agree that if parameter B indicates that the UL grant itself is based on the SCS and / or CP of the UL subband, then the PUSCH resource allocation indicator corresponding to the PUSCH transmission may also be based on the PUSCH candidate resource set of the UL subband (e.g., based on the PUSCH candidate resource set configured for the SBFD slot). If parameter B indicates that the UL grant itself is based on the SCS and / or CP of the UL BWP, then the PUSCH resource allocation indicator corresponding to the PUSCH transmission may be on the PUSCH candidate resource set of the UL BWP (e.g., based on the PUSCH candidate resource set configured for the non-SBFD slot).

[0157] In some embodiments, parameter B may be used to indicate whether the UL grant itself may be based on the UL subband (and the corresponding configuration associated with the UL subband) or the UL BWP (and the configuration associated with the UL BWP). The base station and the UE may also agree that if parameter B indicates that the UL grant itself is based on the UL subband, the PUSCH resource allocation indicator corresponding to the PUSCH transmission may also be based on the PUSCH candidate resource set of the UL subband (e.g., based on the PUSCH candidate resource set configured for the SBFD slot). If parameter B indicates that the UL grant itself is based on the UL BWP, the PUSCH resource allocation indicator corresponding to the PUSCH transmission may be based on the PUSCH candidate resource set of the UL BWP (e.g., based on the PUSCH candidate resource set configured for the non-SBFD slot). The UL subband here may be a cell-specific UL subband or a UE-specific UL subband.

[0158] IV. Method 3 For a UE, the PUSCH candidate resource sets corresponding to SBFD slots (marked as Table 6) and the PUSCH candidate resource sets corresponding to non-SBFD slots (marked as Table 7) may be configured by the base station, respectively, and the same row indexes in Table 6 and Table 7 may be configured with the same k2 value.

[0159] See Tables 6 and 7 below for examples. The k2 value corresponding to index 0 in Table 6 may be equal to the k2 value corresponding to index 0 in Table 7. The k2 value corresponding to index 1 in Table 6 may be equal to the k2 value corresponding to index 1 in Table 7. The k2 value corresponding to index 2 in Table 6 may be equal to the k2 value corresponding to index 2 in Table 7.

[0160] In this way, after the UE may receive an UL grant scheduling a PUSCH transmission, a unique k2 value may be determined from Tables 6 and 7 according to the PUSCH resource allocation indicator in the UL grant. Then, the slot in which the PUSCH transmission is placed may be determined based on the slot in which the UL grant may be placed and the determined k2 value. Furthermore, the type of slot (SBFD slot or non-SBFD slot) may be determined based on the SBFD slot configuration pattern. And, According to the type of slot, the PUSCH resource allocation indicator in the UL grant may be determined to be based on Table 6 or Table 7; According to the slot type, the PUSCH transmission scheduled by the UL grant may be determined based on the SCS and / or CP of the UL subband or the SCS and / or CP of the UL BWP; According to the type of slot, it may be determined that the UL grant itself is based on the UL subband (and the corresponding configuration associated with the UL subband) or the UL BWP (and the configuration associated with the UL BWP).

[0161] [Table 6]

[0162] [Table 7]

[0163] V. Method 4 A new column may be added as a PUSCH candidate resource set for the SBFD slot in the existing PUSCH candidate resource set. The base station and UE may agree that the "PUSCH starting symbol index" and "PUSCH length" in the existing PUSCH candidate resource set may be for a non-SBFD slot or for an UL BWP. The "PUSCH starting symbol index of the (new) SBFD slot" and "PUSCH length of the (new) SBFD slot" added to the existing PUSCH candidate resource set are for the SBFD slot or for an UL subband. An example is shown in Table 8.

[0164] In this way, after the UE receives an UL grant scheduling a PUSCH transmission, a unique k2 value can be determined from Table 8 according to the PUSCH resource allocation indicator in the UL grant. Then, the slot in which the PUSCH transmission can be placed can be determined based on the slot in which the UL grant can be placed and the determined k2 value. Furthermore, the type of slot (SBFD slot or non-SBFD slot) can be determined based on the SBFD slot configuration pattern. And, According to the type of slot, a PUSCH resource allocation indicator in the UL grant may be determined based on a sequence of associated PUSCH resources for SBFD slots or based on a sequence of associated PUSCH resources for non-SBFD slots; According to the slot type, the PUSCH transmission scheduled by the UL grant may be determined based on the SCS and / or CP of the UL subband or the SCS and / or CP of the UL BWP; According to the type of slot, it may be determined that the UL grant itself is based on the UL subband (and the corresponding configuration associated with the UL subband) or the UL BWP (and the configuration associated with the UL BWP).

[0165] [Table 8]

[0166] E. Determining the Repetition Factor in Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) Physical Uplink Control Channel (PUCCH) The following are embodiments relating to determining the repetition factor of a Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) Physical Uplink Control Channel (PUCCH) for msg4 or a Physical Downlink Shared Channel (PDSCH) scheduled by downlink control information (DCI) scrambled by MsgB-RNTI. msg4 may be a PDSCH with UE content resolution identification information in a four-step random access procedure. The PDSCH scheduled by DCI scrambled by MsgB-RNTI may be in the second step of a two-step random access procedure. The following provides several potential options for determining the repetition factor of the HARQ-ACK PUCCH.

[0167] I. Option 1 For base station reception and UE transmission, the repetition factor of the HARQ-ACK PUCCH corresponding to msg4 may be determined based on the repetition factor of the PUSCH scheduled by the RAR grant (also referred to as msg3). For example, the repetition factor of the PUCCH may be determined by reducing the repetition factor of the PUSCH. For example, if the repetition factor of the PUSCH is determined to be equal to 8, the repetition factor of the PUCCH may be determined to be less than 8. For example, a scaling factor may be determined from these values: 0.9, 0.8, 0.7, 0.6, 0.5, 0.95, 0.85, 0.75, 0.65, and 0.55. The scaling factor may be transmitted in a system information block (SIB). The repetition factor of the PUCCH may be determined as a value obtained by multiplying the repetition factor of the PUSCH by the determined scaling factor and rounding up (or down). The UE may transmit the HARQ-ACK PUCCH based on the repetition factor indicated in the DCI. The base station receives the HARQ-ACK PUCCH based on the repetition factor indicated in the DCI.

[0168] II. Option 2 For the base station receiving the HARQ-ACK PUCCH in msg4 and the UE transmitting it, if the repetition factor of the HARQ-ACK PUCCH in msg4 may not be configured in the SIB, the behavior of the UE and the base station is as follows: The UE sends a request to the base station for the repetition factor of the HARQ-ACK PUCCH, and the repetition factor of the HARQ-ACK PUCCH in msg4 may be dynamically indicated by the base station in the DCI corresponding to msg4. The UE may transmit the HARQ-ACK PUCCH based on the repetition factor indicated in the DCI. The base station may receive the HARQ-ACK PUCCH based on the repetition factor indicated in the DCI.

[0169] For a base station receiving a HARQ-ACK PUCCH in msg4 and a UE transmitting it, if only one repetition factor of the HARQ-ACK PUCCH corresponding to msg4 can be configured in the SIB, the behaviors of the base station and the UE may be as follows: the UE may send a request to the base station for a repetition factor of the HARQ-ACK PUCCH, and the repetition factor of the HARQ-ACK PUCCH in msg4 may be dynamically indicated by the base station in the DCI scheduling msg4. However, if the repetition factor of the HARQ-ACK PUCCH in msg4 does not need to be dynamically indicated by the base station in the DCI scheduling msg4, the repetition factor in the SIB may be used. Here, the indicated repetition factor may be a repetition factor other than the repetition factor in the SIB. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0170] III. Option 3 For a base station receiving the HARQ-ACK PUCCH in msg4 and a UE transmitting it, if the repetition factor of the HARQ-ACK PUCCH in msg4 may not be configured in the SIB, the behaviors of the base station and the UE may be as follows: The UE may send a request to the base station for the repetition factor of the HARQ-ACK PUCCH, and the repetition factor of the HARQ-ACK PUCCH may be equal to the repetition factor of msg3, or the repetition factor of the HARQ-ACK PUCCH may be determined via Option 1 above. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0171] For a base station receiving a HARQ-ACK PUCCH in msg4 and a UE transmitting it, if only one repetition factor of the HARQ-ACK PUCCH corresponding to msg4 can be configured in the SIB, the behaviors of the base station and the UE may be as follows: Base Station and UE Behavior: The UE may send a request to the base station for a repetition factor of the HARQ-ACK PUCCH, and the repetition factor of the HARQ-ACK PUCCH may be equal to the repetition factor of msg3, or the repetition factor of the HARQ-ACK PUCCH may be determined via Option 1 above. Here, the repetition factor of the SIB may be different from the repetition factor of msg3. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0172] IV. Option 4 For the base station receiving the HARQ-ACK PUCCH in msg4 and the UE transmitting it, if the repetition factor of the HARQ-ACK PUCCH in msg4 may not be configured in the SIB, the behavior of the base station and the UE is as follows: The UE may send a request to the base station for the repetition factor of the HARQ-ACK PUCCH, and then a predetermined repetition factor may be used for the HARQ-ACK PUCCH. The predetermined repetition factor may be fixed in the specification protocol. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0173] For a base station receiving a HARQ-ACK PUCCH for msg4 and a UE transmitting it, if only one repetition factor for the HARQ-ACK PUCCH corresponding to msg4 can be configured in the SIB, the behavior of the base station and the UE is as follows: The UE may send a request for a repetition factor for the HARQ-ACK PUCCH to the base station, and then a predetermined repetition factor may be used for the HARQ-ACK PUCCH, where the predetermined repetition factor may be fixed in the specification protocol. Alternatively, the predetermined repetition factor may be determined based on the above repetition factor in the SIB. For example, the predetermined repetition factor may be equal to n times the above repetition factor in the SIB, where n is equal to 2. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0174] V. Option 5 For a base station receiving the HARQ-ACK PUCCH in msg4 and a UE transmitting it, if the repetition factor of the HARQ-ACK PUCCH in msg4 may not be configured in the SIB, the behaviors of the base station and the UE may be as follows: The UE may report the repetition factor of the HARQ-ACK PUCCH to the base station, and the reported repetition factor may be used for the HARQ-ACK PUCCH. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0175] For a base station receiving a HARQ-ACK PUCCH for msg4 and a UE transmitting it, if only one repetition factor of the HARQ-ACK PUCCH corresponding to msg4 can be configured in the SIB, the behavior of the base station and the UE may be as follows: The UE may report a repetition factor of the HARQ-ACK PUCCH to the base station, and the reported repetition factor may be used for the HARQ-ACK PUCCH. Here, the repetition factor reported by the UE may be different from the repetition factor in the SIB. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0176] VI. Option 6 For a base station receiving the HARQ-ACK PUCCH in msg4 and a UE transmitting it, if the repetition factor of the HARQ-ACK PUCCH in msg4 may not be configured in the SIB, the behaviors of the base station and the UE may be as follows: The UE may report the repetition factor of the HARQ-ACK PUCCH to the base station. If a repetition factor may be indicated by the base station in the DCI of msg4 for the HARQ-ACK PUCCH, the repetition factor indicated by the base station may be used for the HARQ-ACK PUCCH. If a repetition factor may not be indicated by the base station in the DCI of msg4, the reported repetition factor may be used for the HARQ-ACK PUCCH. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0177] For a base station receiving a HARQ-ACK PUCCH in msg4 and a UE transmitting it, if only one repetition factor of the HARQ-ACK PUCCH corresponding to msg4 can be configured in the SIB, the behaviors of the base station and the UE may be as follows: The UE may report the repetition factor of the HARQ-ACK PUCCH to the base station. If a repetition factor can be indicated by the base station in the DCI of msg4 for the HARQ-ACK PUCCH, the repetition factor indicated by the base station may be used for the HARQ-ACK PUCCH. If a repetition factor does not need to be indicated by the base station in the DCI of msg4, the reported repetition factor may be used for the HARQ-ACK PUCCH. Here, the repetition factor reported by the UE may be different from the above repetition factor in the SIB. The UE may transmit the HARQ-ACK PUCCH based on the finally determined repetition factor. The base station may receive the HARQ-ACK PUCCH based on the finally determined repetition factor.

[0178] VII.
