Physical uplink channel transmission in sub-band full duplex symbols

Abstract

Subband full duplex (SBFD) may allow a user equipment (UE) to transmit and receive both in the same frequency band using an uplink subband and one or more downlink subbands. Although SBFD can only be configured on some slots, the configuration of the physical uplink channel can be applied to all symbols. The UE receives a configuration of a physical uplink channel. The configuration is applicable to both SBFD symbols and non-SBFD symbols. The UE receives an indication of resources for transmission over at least one slot configured with the SBFD symbol. The UE determines whether to transmit the physical uplink channel on the resource based on whether all resource blocks of the physical uplink channel are within an uplink subband.

Background Art Technical Field

[0003] The present disclosure relates generally to communication systems, and more particularly, to physical uplink (UL) channel transmission in sub-band full-duplex (SBFD) symbols.

[0004] introduction

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continued mobile broadband evolution promulgated by the 3rd Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)) and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Certain aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. Further improvements to 5G NR technology are needed. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the Invention

[0026] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations with which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring such concepts. Although the following description may focus on 5G NR, the concepts described herein may be applicable to other similar fields, such as LTE, LTE-A, CDMA, GSM, and other wireless technologies.

[0027] Full-duplex communication allows wireless communication devices to transmit and receive simultaneously. In-band full-duplex (IBFD) may refer to transmission and reception on the same time and frequency resources. The uplink (UL) and downlink (DL) may share the same IBFD time and frequency resources, which may include fully overlapping resources or partially overlapping resources. Subband frequency division duplex (SBFD) may refer to simultaneous transmission and reception on different frequency resources. DL resources may be separated from UL resources in the frequency domain by a guard interval. For example, a UL subband may be configured as a UL resource for SBFD. A UL subband may be located in the middle of a DL resource to separate UL transmissions from adjacent frequency resources. A resource element (RE) may refer to the basic unit of resources, which is a subcarrier per symbol. REs may be grouped into resource blocks (RBs) within a symbol for scheduling purposes. In some cases, an SBFD-capable UE may be configured for SBFD on a UL subband in certain time domain resources (such as a time slot or symbol). For example, a time slot may be configured as DL, UL, or SBFD. Any symbol in an SBFD time slot may be considered an SBFD symbol. Similarly, one or more symbols within a timeslot (e.g., a DL timeslot) can be designated as SBFD symbols. SBFD symbols can provide flexibility when scheduling physical UL channels (such as the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH)) from SBFD-aware UEs. For example, a UE may be able to transmit in a DL timeslot on an SBFD symbol without waiting for a UL timeslot or symbol.

[0028] Using SBFD symbols for physical UL channels may mean that additional configuration of resources specific to SBFD is required. For example, the conventional UL configuration for PUCCH may define a PUCCH resource set that includes multiple PUCCH resources for the UE. One of the configured resources for a specific PUCCH transmission within one of the PUCCH resource sets may be indicated to the UE via the physical resource indication (PRI) field of the DL control information (DCI) or through RRC configuration (e.g., a higher layer configuration of the PUCCH resource ID for carrying persistent or semi-persistent (P / SP) channel state information (CSI) or the PUCCH resource ID for scheduling requests (SR) and beam failure reports (BFR)). Similarly, the PUSCH may be configured by configuration grants or resources may be dynamically indicated to the PUSCH via the time domain resource allocation (TDRA) and frequency domain resource allocation (FDRA) in the DCI. In some cases, the conventional configuration of UL resources may not be sufficient for SBFD symbols because the available resources (e.g., RBs) in SBFD symbols may be different compared to UL symbols. One approach for SBFD symbols is to provide a second configuration of UL channels for SBFD symbols. However, the second configuration may increase signaling and complexity. Therefore, a technique is needed to transmit the physical UL channel based on a resource configuration applicable to both SBFD symbols and non-SBFD symbols.

[0029] In addition, some transmissions may have the characteristic of changing the resources used for transmission. For example, intra-slot frequency hopping may change the frequency domain resources used for transmission on different symbols within a slot by changing the starting RB used for the uplink channel. Inter-slot frequency hopping may change the frequency domain resources used for transmission across one or more slot boundaries. Repetition may extend the time domain resources used for one or more repetitions of transmission on available resources. In some cases, repetition may invoke inter-slot frequency hopping (e.g., for PUCCH transmission). When intra-slot frequency hopping, inter-slot frequency hopping, or repetition changes the resources used for transmission, the new or additional resources may not be within the configured UL subband for SBFD.

[0030] In one aspect, the present disclosure provides a single configuration for a user equipment (UE) to receive a physical UL channel applicable to both SBFD and non-SBFD symbols. The non-SBFD symbols may include UL symbols and flexible symbols. For example, the configuration may be a PUCCH configuration that is used to configure a PUCCH resource set including PUCCH resources. The UE may receive an indication of resources for transmission on at least one time slot configured with the SBFD symbol. For example, the UE may receive a DCI indicating PUCCH resources or time domain resource allocation (TDRA) and frequency domain resource allocation (FDRA) for PUSCH. In some cases, for example, due to intra-slot or inter-slot frequency hopping of the transmission, the size of the transmission (e.g., a certain number of RBs) may not be within the UL subband. For example, the indication may select a PUCCH resource that starts in the middle of the UL subband used for SBFD but extends into the DL subband. The UE may determine whether to transmit the physical UL channel on the resource based on whether all resource blocks of the physical UL channel are within the UL subband.

[0031] In some specific implementations, when any resource block of the physical UL channel is outside the UL subband, the UE may discard (e.g., not transmit) the physical UL channel. In other specific implementations, the UE may attempt to adapt the resources to accommodate all resource blocks of the physical UL channel within the UL subband. For example, the UE may move a certain number of resource blocks to the UL subband or extend a certain number of symbols to transmit the resource blocks only on the resources within the UL subband. In addition, when intra-slot hopping, inter-slot hopping and / or repetition are configured, the UE may determine whether to apply the intra-slot hopping, inter-slot hopping and / or repetition based on whether the transmission is within the UL subband. In some specific implementations, the UE may also adapt the resources and / or parameters (e.g., starting RB) for intra-slot hopping, inter-slot hopping and / or repetition, thereby transmitting the physical UL channel on the UL subband.

[0032] Certain implementations of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. Compared to the second configuration for SBFD transmission, the configuration applicable to both SBFD and non-SBFD symbols can provide SBFD flexibility with less signaling overhead and complexity. When all resource blocks are within the UL subband, the UE can transmit physical UL channels on SBFD symbols, or the resources can be adapted to accommodate such transmission. Additionally, intra-slot frequency hopping, inter-slot frequency hopping, and / or repetition can be implemented on both SBFD and non-SBFD symbols. This enables the gNB to utilize frequency resources within the UL subband and avoid dropping uplink channels.

[0033] Several aspects of telecommunication systems will now be presented with reference to various apparatuses and methods. These apparatuses and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0034] As an example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system", which includes one or more processors. The example of a processor includes a microprocessor, a microcontroller, a graphics processing unit (GPU), a central processing unit (CPU), an application processor, a digital signal processor (DSP), a reduced instruction set computing (RISC) processor, a system on a chip (SoC), a baseband processor, a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gating logic, a discrete hardware circuit and other suitable hardware configured to perform various functionalities described throughout this disclosure. One or more processors in a processing system can execute software. Whether it is referred to as software, firmware, middleware, microcode, hardware description language or other names, software should be broadly interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, processes, functions, etc.

[0035] Therefore, in one or more example embodiments, the described functions can be implemented with hardware, software or any combination thereof. If implemented in software, the functions can be stored or encoded on a computer-readable medium as one or more instructions or codes. Computer-readable media include computer storage media. Storage media can be any available medium that can be accessed by a computer. By way of example and not limitation, such computer-readable media can include random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, a combination of the above-mentioned types of computer-readable media or any other medium that can be used to store computer-executable code in the form of instructions or data structures that can be accessed by a computer.

[0036] Figure 11 is a diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also known as a wireless wide area network (WWAN)) includes a base station 102, a UE 104, an evolved packet core (EPC) 160, and another core network (e.g., a 5G core (5GC) 190). The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell includes a base station. Small cells include femto cells, pico cells, and micro cells.

[0037] One or more of UEs 104 may include an SBFD component 140 configured to transmit a physical UL channel on SBFD symbols. SBFD component 140 may include a configuration component 142 configured to receive a configuration of the physical UL channel. The configuration applies to both SBFD symbols and non-SBFD symbols. SBFD component 140 may include a resource component 144 configured to receive an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol. SBFD component 140 may include a transmission component 146 configured to determine whether to transmit the physical UL channel on the resources based on whether all resource blocks of the physical UL channel are within a UL subband. Figure 8 UE 104 and additional components of SBFD component 140 are illustrated in FIG.

[0038] In one aspect, one or more of base stations 102 may include an SBFD scheduling component 120 that performs various base station actions as described herein. For example, SBFD scheduling component 120 may include an UL configuration component 122 that is configured to transmit a configuration of a physical UL channel to a UE, the configuration applicable to both SBFD symbols and non-SBFD symbols. SBFD scheduling component 120 may include an indication Tx component 124 that is configured to transmit an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol. SBFD scheduling component 120 may include an UL reception component 126 that is configured to determine whether the UE should transmit the physical UL channel on the resources based on whether all resource blocks of the physical UL channel are within a UL subband. Figure 7 Additional components of base station 102 and SBFD scheduling component 120 are illustrated in FIG.

[0039] Base stations 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with the EPC 160 via a backhaul link 132 (e.g., an S1 interface). The backhaul link 132 can be wired or wireless. Base stations 102 configured for 5G NR (collectively referred to as the Next Generation RAN (NG-RAN)) can interface with the 5GC 190 via a backhaul link 184. The backhaul link 184 can be wired or wireless. Among other functions, the base station 102 can perform one or more of the following functions: delivery of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracking, RAN information management (RIM), paging, positioning, and delivery of warning messages. Base stations 102 may communicate with each other directly or indirectly (e.g., through EPC 160 or 5GC 190) over a backhaul link 134 (e.g., an X2 interface). Backhaul link 134 may be wired or wireless.

[0040] Base stations 102 can communicate wirelessly with UEs 104. Each of base stations 102 can provide communication coverage for a corresponding geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102′ can have a coverage area 110′ that overlaps with the coverage area 110 of one or more macro base stations 102. A network that includes both small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include home evolved Node Bs (eNBs) (HeNBs), which can provide service to a restricted group known as a closed subscriber group (CSG). The communication link 112 between base station 102 and UE 104 can include uplink (UL) (also known as reverse link) transmissions from UE 104 to base station 102 and / or downlink (DL) (also known as forward link) transmissions from base station 102 to UE 104. The communication link 112 can use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link can be over one or more carriers. Base station 102 / UE 104 may use spectrum with a bandwidth of up to Y MHz (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.) for each carrier allocated in the carrier aggregation for a total of up to Yx MHz (x component carriers) for transmission in each direction. These carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL). Component carriers may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carriers may be referred to as secondary cells (SCells).

[0041] Some UEs 104 may communicate with each other using device-to-device (D2D) communication links 158. The D2D communication links 158 may use the DL / UL WWAN spectrum. The D2D communication links 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and a physical sidelink feedback channel (PSFCH). D2D communication may be accomplished via various wireless D2D communication systems, such as, for example, FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

[0042] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in the 5 GHz unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) to determine whether the channel is available before communicating.

[0043] Small cell 102' can operate in licensed and / or unlicensed spectrum. When operating in unlicensed spectrum, small cell 102' can employ NR and utilize the same 5 GHz unlicensed spectrum as used by Wi-Fi AP 150. Small cell 102' employing NR in unlicensed spectrum can improve access network coverage and / or increase access network capacity.

[0044] Base station 102 (whether a small cell 102' or a large cell (e.g., a macro base station)) may include an eNB, a gNodeB (gNB), or other types of base stations. Some base stations, such as gNB 180, may operate in one or more frequency bands within the electromagnetic spectrum.

[0045] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in various documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified by the International Telecommunication Union (ITU) as the "millimeter wave" (mmW) band.

[0046] With all of the above in mind, unless otherwise specified, it should be understood that, if used herein, the term "sub-6 GHz," etc., may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Furthermore, unless otherwise specified, it should be understood that, if used herein, the term "millimeter wave," etc., may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band. Communications using mmW radio frequency bands have extremely high path loss and a short range. mmW base station 180 may utilize beamforming 182 with UE 104 to compensate for the path loss and short range.

[0047] Base station 180 may transmit beamformed signals in one or more transmit directions 182′ to UE 104. UE 104 may receive beamformed signals from base station 180 in one or more receive directions 182″. UE 104 may also transmit beamformed signals in one or more transmit directions to base station 180. Base station 180 may receive beamformed signals in one or more receive directions from UE 104. Base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of base station 180 / UE 104. The transmit direction and receive direction of base station 180 may be the same or different. The transmit direction and receive direction of UE 104 may be the same or different.

[0048] EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, a Multimedia Broadcast Multicast Service (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. MME 162 may communicate with a Home Subscriber Server (HSS) 174. MME 162 is a control node that handles signaling between UE 104 and EPC 160. Generally speaking, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are transmitted through Serving Gateway 166, which itself is connected to PDN Gateway 172. PDN Gateway 172 provides UE IP address allocation and other functions. PDN Gateway 172 and BM-SC 170 are connected to IP Services 176. IP Services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), PS streaming services, and / or other IP services. The BM-SC 170 provides functionality for MBMS user service provisioning and delivery. It serves as the entry point for content providers' MBMS delivery, authorizes and initiates MBMS bearer services within the Public Land Mobile Network (PLMN), and schedules MBMS delivery. The MBMS Gateway 168 distributes MBMS services to base stations 102 within a Multicast Broadcast Single Frequency Network (MBSFN) area that broadcasts specific services. It is also responsible for session management (start / stop) and for collecting eMBMS-related billing information.

[0049] 5GC 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. AMF 192 may communicate with a unified data management (UDM) 196. AMF 192 is a control node that handles signaling between UE 104 and 5GC 190. Generally speaking, AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are passed through UPF 195. UPF 195 provides UE IP address allocation and other functions. UPF 195 is connected to IP services 197. IP services 197 may include the Internet, intranet, IP multimedia subsystem (IMS), PS streaming services, and / or other IP services.

[0050] A base station may also be referred to as a gNB, Node B, evolved Node B (eNB), access point, base transceiver station, radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), transmit receive point (TRP), or some other suitable terminology. Base station 102 provides an access point to EPC 160 or 5GC 190 for UE 104. Examples of UE 104 include a cellular phone, a smartphone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., an MP3 player), a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, or any other similarly functional device. Some of UE 104 may be referred to as IoT devices (e.g., a parking meter, a gas pump, a toaster, a vehicle, a heart monitor, etc.). UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.

[0051] Figures 2A to 2D is a resource diagram illustrating an example frame structure and channels that may be used for UL transmissions, DL transmissions, and sidelink transmissions to a UE 104 that includes the SBFD component 140. Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2D FIG28 is a diagram illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be FDD, where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to either DL or UL, or TDD, where for a particular set of subcarriers (carrier system bandwidth), subframes within that subcarrier set are dedicated to both DL and UL. Figure 2A 、 Figure 2C In the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and X can be used flexibly between DL / UL, and subframe 3 is configured with slot format 34 (most of which are UL). Although subframes 3 and 4 are shown as having slot formats 34 and 28, respectively, any particular subframe can be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are all DL and all UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. The UE is configured with the slot format via the received slot format indicator (SFI) (dynamically configured via DL control information (DCI) or semi-statically / statically configured via radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0052] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10ms) may be divided into 10 equally sized subframes (1ms). Each subframe may include one or more time slots. A subframe may also include a mini-slot, which may include 7, 4, or 2 symbols. Each time slot may include 7 or 14 symbols, depending on the time slot configuration. For time slot configuration 0, each time slot may include 14 symbols, and for time slot configuration 1, each time slot may include 7 symbols. The symbols on the DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. The symbols on the UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also known as single carrier frequency division multiple access (SC-FDMA) symbols) (for power-limited scenarios; limited to single-stream transmission). The number of time slots within a subframe is based on the time slot configuration and parameter set (numerology). For slot configuration 0, different parameter sets μ0 to 5 allow 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, different parameter sets 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and parameter set μ, there are 14 symbols per slot and 2 per subframe. μtime slots. The subcarrier spacing and symbol length / duration are functions of the parameter set. The subcarrier spacing can be equal to 2 μ *15kHz, where μ is parameter set 0 to 5. Therefore, the subcarrier spacing for parameter set μ=0 is 15kHz, and the subcarrier spacing for parameter set μ=5 is 480kHz. Symbol length / duration is inversely related to subcarrier spacing. Figures 2A to 2D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ=0 with 1 slot per subframe. The subcarrier spacing is 15 kHz and the symbol duration is approximately 66.7 μs.

[0053] A resource grid can be used to represent the frame structure. Each slot includes a resource block (RB) (also known as a physical RB (PRB)) that extends over 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0054] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RSs may include demodulation RSs (DM-RSs) (denoted as Rx for a particular configuration, where 100x is the port number, but other DM-RS configurations are also possible) and channel state information reference signals (CSI-RSs) for channel estimation at the UE. The RSs may also include beamforming RSs (BRSs), beam refinement RSs (BRRSs), and phase tracking RSs (PT-RSs).

[0055] Figure 2B Examples of various DL channels within a subframe of a frame are illustrated. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE includes nine RE groups (REGs), and each REG includes four consecutive REs in an OFDM symbol. The primary synchronization signal (PSS) may be within symbol 2 of a specific subframe of the frame. The PSS is used by the UE 104 to determine the subframe / symbol timing and the physical layer identification. The secondary synchronization signal (SSS) may be within symbol 4 of a specific subframe of the frame. The SSS is used by the UE to determine the physical layer cell identification group number and the radio frame timing. Based on the physical layer identification and the physical layer cell identification group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the position of the aforementioned DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not sent through the PBCH (such as System Information Blocks (SIBs)), and paging messages.

[0056] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a specific configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit the DM-RS for the physical UL control channel (PUCCH) and the DM-RS for the physical UL shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or the first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is transmitted and depending on the specific PUCCH format used, the PUCCH DM-RS may be transmitted in different configurations. Although not shown, the UE may transmit a sounding reference signal (SRS). The SRS may be used by the base station for channel quality estimation to enable frequency-dependent scheduling of the UL.

[0057] Figure 2D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at the position indicated in one configuration. The PUCCH carries UL control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0058] Figure 33 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, IP packets from the EPC 160 may be provided to the controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes the radio resource control (RRC) layer, and layer 2 includes the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer, the radio link control (RLC) layer, and the medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (ciphering, deciphering, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with delivery of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0059] The transmit (Tx) processor 316 and receive (Rx) processor 370 implement Layer 1 functionality associated with various signal processing functions. Layer 1, which includes the physical (PHY) layer, may include error detection on transport channels, forward error correction (FEC) coding / decoding of transport channels, interleaving, rate matching, mapping onto physical channels, modulation / demodulation of physical channels, and MIMO antenna processing. The Tx processor 316 handles the mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), M-phase-shift keying (M-PSK), and M-quadrature amplitude modulation (M-QAM). The coded and modulated symbols are then separated into parallel streams. Each stream is then mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., a pilot) in the time and / or frequency domain, and then combined using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying the time-domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation schemes, as well as for spatial processing. The channel estimates may be derived based on a reference signal and / or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318Tx. Each transmitter 318Tx may modulate an RF carrier with a corresponding spatial stream for transmission.

[0060] At the UE 350, each receiver 354Rx receives a signal via its corresponding antenna 352. Each receiver 354Rx recovers the information modulated onto the RF carrier and provides the information to a receive (Rx) processor 356. The Tx processor 368 and the Rx processor 356 implement Layer 1 functionality associated with various signal processing functions. The Rx processor 356 can perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined into a single OFDM symbol stream by the Rx processor 356. The Rx processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, as well as the reference signal, are recovered and demodulated by determining the most likely signal constellation point transmitted by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by base station 310. The data and control signals are then provided to a controller / processor 359, which implements layer 3 and layer 2 functionality.

[0061] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets from the EPC 160 or 5GC 190. The controller / processor 359 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0062] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0063] The channel estimates derived by the channel estimator 358 from a reference signal or feedback sent by the base station 310 can be used by the Tx processor 368 to select the appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the Tx processor 368 can be provided to different antennas 352 via separate transmitters 354Tx. Each transmitter 354Tx can modulate an RF carrier with a corresponding spatial stream for transmission.

[0064] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318Rx receives a signal through its corresponding antenna 320. Each receiver 318Rx recovers information modulated onto an RF carrier and provides the information to an Rx processor 370.

[0065] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets from the UE 350. The IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0066] At least one of the Tx processor 368, the Rx processor 356, and the controller / processor 359 may be configured to perform Figure 1 For example, the memory 360 may include executable instructions that define the SBFD component 140. The Tx processor 368, the Rx processor 356, and / or the controller / processor 359 may be configured to execute the SBFD component 140.

[0067] At least one of the Tx processor 316, the Rx processor 370, and the controller / processor 375 may be configured to perform Figure 1 For example, the memory 376 may include executable instructions that define the SBFD scheduling component 120. The Tx processor 316, the Rx processor 370, and / or the controller / processor 375 may be configured to execute the SBFD scheduling component 120.

[0068] Figure 4 4 is a resource diagram 400 illustrating available UL resources for different time slot types. A bandwidth portion 402 may include a certain number of RBs. An SBFD configuration may indicate the UL subbands 440 and time domain resources configured for SBFD. Generally, the UL subbands 440 are located near the center of the bandwidth portion 402, separated from other frequency domain resources by DL subbands. It should be understood that the number of RBs in the bandwidth portion 402 and UL subbands 440 is merely illustrative, and a larger or smaller number may be configured.

[0069] The UL resources may include SBFD UL RBs 406 on SBFD symbols 422 and non-SBFD UL RBs 404 on non-SBFD symbols 424, which include flexible (X) symbols and uplink (U) symbols. The SBFD symbols 422 may be DL symbols or X symbols configured with UL subbands 440. Therefore, only SBFD UL RBs 406 located in UL subbands 440 may be used for UL transmission in the SBFD symbols 422.

[0070] Slot 410 is a DL-centric slot without SBFD configuration (e.g., slot format 34). Only symbols 12 and 13 are available for UL transmission. Slot 430 is a UL-centric slot (e.g., slot format 28) in which symbols 1-13 are available for UL transmission.

[0071] Slot 420 is an SBFD slot. Although slot 420 has the same slot format as slot 410, slot 420 is configured for SBFD using UL subband 440. Therefore, in slot 420, SBFD symbols 422 can be used for UL transmission on SBFD UL RBs and for DL ​​transmission on the remaining RBs.

[0072] Figure 5 5 is a resource diagram 500 illustrating an example of a PUCCH resource set 510 compared to UL resources in an example SBFD time slot 420. The PUCCH resource set 510 may be configured as part of a PUCCH configuration. The PUCCH resource set 510 may define one or more PUCCH resources that may be selected for PUCCH transmission based on the size of the UL control information (UCI) payload. For example, the PUCCH resource set 510 may include up to 12 PUCCH resources (8 are illustrated). The base station may use an indication, such as a DCI including a PRI field, to select the PUCCH resources for transmission. For an UL time slot (e.g., time slot 430), all configured PUCCH resources in the PUCCH resource set 510 may be within a non-SBFD UL RB. However, for SBFD time slot 420, not all configured PUCCH resources in the PUCCH resource set 510 may be within an SBFD RB. For example, only the PUCCH resource 512 may be entirely within the UL subband 440. Additionally, in case of intra-slot frequency hopping, inter-slot frequency hopping, and / or repetition, the PUCCH resource 512 may not be within the UL subband 440 on some symbols.

[0073] PUSCH may also be scheduled in a manner that is not aligned with SBFD RBs. For example, when PUSCH is configured via a configuration grant or scheduled by DCI, the indicated resources may not be within the UL subband 440 in the case of transport block (TB) processing, intra-slot hopping, inter-slot hopping, and / or repetition over multiple slots.

[0074] Figure 6 is a message diagram 600 illustrating example messages for transmission of an UL physical channel. Base station 102 may be a serving base station for UE 104. UE 104 may transmit UE capabilities 610 indicating UE 104's capability for SBFD.

[0075] Base station 102 may configure physical UL channel configuration 622 to UE 104. For example, base station 102 may send physical UL channel configuration 622 via RRC signaling 620. Physical UL channel configuration 622 may include, for example, a PUCCH configuration 630 and / or a PUSCH configuration 640. PUCCH configuration 630 may include a PUCCH resource set 632 defining one or more PUCCH resources 634. For example, PUCCH resource set 632 may correspond to PUCCH resource set 510, and PUCCH resource 634 may correspond to one of PUCCH resources 512, 514, or 516. PUCCH configuration 630 may include a hopping parameter 636 indicating whether the PUCCH is configured for intra-slot frequency hopping and / or inter-slot frequency hopping. Hopping parameter 636 may define a second hop offset. PUCCH configuration 630 may include a repetition parameter 638.

[0076] The PUSCH configuration 640 may include resources 642, frequency hopping parameters 644, and / or repetition parameters 646. Resources 642 may indicate the starting resource block for PUSCH transmission. Frequency hopping parameters 644 may include a list of RB offset candidates for the second hop. Repetition parameters 646 may include a certain number of repetitions.

[0077] Base station 102 may send an indication of the resources used for the transmission. For example, the indication may be a DCI 650. DCI 650 may include a PRI 652 indicating a PUCCH resource index (e.g., PUCCH resource 512). DCI 650 may include an FDRA 654 and a TDRA 656 indicating the resources used for the PUSCH. As discussed above, when the physical UL channel configuration 622 applies to both SBFD symbols 422 and non-SBFD symbols 424, the resources indicated by DCI 650 may not be within the UL subband 440.

[0078] When the DCI 650 indicates resources including the SBFD symbol 422, the UE 104 can determine whether to transmit the physical UL channel 660 on the resources indicated by the DCI 650 based on whether all RBs of the physical UL channel 660 are within the UL subband 440. In some implementations, the UE 104 can determine to drop the physical UL channel 660 when any RB of the physical UL channel 660 is not within the UL subband. In some implementations, the UE 104 can adapt the resources indicated by the DCI 650 to accommodate all resource blocks of the physical UL channel 660 within the UL subband. When the physical UL channel configuration 622 includes the repetition parameter 638 or 646, the UE 104 can also determine whether to transmit the repetition 670 based on whether all RBs of the repetition 670 are within the UL subband 440.

[0079] In some implementations, adapting resources to accommodate all resource blocks of a physical UL channel within a UL subband may include adjusting a starting physical resource block (PRB) of the resources by an offset configured by the network or derived by the UE. For example, PUCCH resource 634 or resource 642 may be defined by a starting PRB, a number of RBs, and a number of symbols. For example, referring to Figure 5 , the resource 514 may have a starting RB outside the UL subband 440. The offset may be the number of RBs used to shift the resource 514 in the frequency domain (e.g., 2). In some implementations, the PUCCH configuration 630 may include an offset. In some implementations, the UE 104 may determine the offset as, for example, the minimum number of RBs that shifts the resource 514 to within the UL subband 440. The offset may be positive or negative. Alternatively, the RB offset may be determined by the UE as the first RB in the UL subband. In this case, the starting RB and RB offset for UL transmission may be interpreted with reference to the lowest RB index in the UL subband.

[0080] In some implementations, adapting resources may include selecting a starting resource block and a number of resource blocks for resources from a list of resources for non-SBFD symbols and for SBFD symbols. For example, the PUCCH configuration 630 may define a list of starting PRBs and a set of a number of RBs. The sets in the list may be associated with SBFD symbols and non-SBFD symbols. The UE 104 may select the corresponding set from the list. In some cases, resources (e.g., PUCCH resources 516) may include a larger number of resources than the number of RBs in the UL subband. The UE may adjust the number of symbols based on the number of resource blocks to maintain the same size of the resources. For example, the UE 104 may adapt the resources 516 for transmission on 4 symbols on the UL subband 440, thereby transmitting the same number of RBs. Alternatively, the UE may adapt the time domain resources based on the number of RBs to maintain the maximum decoding rate of the physical channel specific to the SBFD symbols.

[0081] In some implementations, resources in a slot configured with an SBFD symbol are configured with a starting resource block specific to the SBFD symbol (e.g., startRB-SBFD) and a number of resource blocks (e.g., nrofRBs-SBFD). Resources in a slot configured with an SBFD symbol may also be configured with a starting symbol specific to the SBFD symbol (e.g., startSymbol_SBFD) and a number of symbols (e.g., noSymbols_SBFD).

[0082] In some implementations, resources on a time slot configured with an SBFD symbol are configured with a starting resource block applicable to both non-SBFD symbols and SBFD symbols, a starting resource block specific to SBFD symbols, or both. Resources on a time slot configured with an SBFD symbol are configured with a certain number of RBs applicable to both non-SBFD symbols and SBFD symbols, a certain number of RBs specific to SBFD symbols, or both.

[0083] Frequency hopping within a time slot may include changing the frequency of the transmission within the time slot. That is, different symbols of the transmission may be sent on different RBs. The change of frequency may be configured as the second hop PRB in the frequency hopping parameters 636 or 644.

[0084] Intra-slot frequency hopping may result in an indication of resources outside the UL sub-band 440 on the SBFD symbol 422. In some implementations, intra-slot frequency hopping may be disabled on the SBFD symbol 422. In some implementations, intra-slot frequency hopping may be selectively disabled when at least one of the configured second hop physical resource blocks is outside the UL sub-band.

[0085] In some implementations, the UE 104 may adapt resources for intra-slot frequency hopping. For example, the UE 104 may apply the same offset to both the starting PRB and the second hop PRB of the resource. In some implementations, the UE 104 may apply a first offset to the starting PRB of the resource and a second offset to the second hop PRB. In some implementations, the UE is configured with a starting PRB and a second hop PRB specific to SBFD symbols (e.g., in hopping parameters 636 or 644), in which case intra-slot frequency hopping is enabled. The UE 104 may also be configured with a certain number of RBs specific to SBFD symbols. In some implementations, the UE is configured with a list of starting PRBs, second hop PRBs, and a certain number of resource blocks. The list includes at least a first set of values ​​applicable to non-SBFD symbols and a second set of values ​​applicable to SBFD symbols. In some implementations, the physical UL channel is scheduled or activated by a DCI 650 indicating the selected second hop PRB for the physical UL channel 660.

[0086] Repeating may include repeating the physical UL channel on a second set of resources (e.g., in another time slot) based on the resources indicated by DCI 650. The UE may determine the second set of resources based on whether the time slot is considered an available time slot. For example, the UL time slot may be considered an available time slot. In some cases, the SBFD time slot may also be considered an available time slot. The UE may determine whether to transmit the physical UL channel 660 on the time slot configured with the SBFD symbol (e.g., time slot 420) using the configured number of repetitions or the indicated number of repetitions based on whether time slot 420 is considered an available time slot for repetition.

[0087] In some implementations, the SBFD slot 420 can always be considered an available slot for repetition. If any resource blocks of the repetition are outside the UL subband, the UE 104 can discard the repetition of the physical UL channel on the SBFD slot 420. Alternatively, the UE 104 can adapt the resources for repetition to accommodate all resource blocks of the repetition within the UL subband 440. For example, the definition of available slots in non-paired spectrum may apply to a certain number of PUCCH repetition slots for PUCCH transmission, starting from the slot indicated to the UE for HARQ-ACK reporting or starting from the slot determined to be used for SR reporting or for CSI reporting, the slot having: a UL symbol, or a flexible symbol that is not an SS / PBCH block symbol provided by startingSymbolIndex as the first symbol, or a SBFD symbol (DL symbol with configured UL subband), and a number of consecutive UL symbols equal to or greater than the number of symbols provided by nrofsymbols, or flexible symbols that are not SS / PBCH block symbols, or DL ​​symbols with configured UL subband starting from the first symbol. If the UE determines that the number of PRBs available for PUCCH transmission for a repetition in a slot is less than the value of PRBs provided by startingPRB or secondHopPRB and nrofPRBs, then for the corresponding PUCCH format, the UE does not send PUCCH repetitions in the slot.

[0088] Similarly, for PUSCH transmissions with repetition (e.g., when AvailableSlotCounting is enabled, and in the case where K>1), the available slots may be defined based on tdd-UL-DLConfigurationCommon, tdd-UL-DL-ConfigurationDedicated, the UL and DL subband configurations and ssb-PositionsInBurst, and the TDRA information field value of DCI format 0_1 ​​or 0_2. If at least one of the symbols indicated by the index row of the used resource allocation table in a slot overlaps with a DL symbol indicated by tdd-UL-DLConfigurationCommon or tdd-UL-DLConfigurationDedicated (if there is no configured UL subband) or a symbol of an SS / PBCH block with an index provided by ssb-PositionsInBurst, then the slot is not counted in the number of NK slots used for PUSCH transmissions of PUSCH repetition type A scheduled by DCI format 0_1 ​​or 0_2. If the UE determines that for repetition of PUSCH transmission in a slot, the number of PRBs available for PUSCH transmission is less than the value of PRBs provided by the FDRA bit field of DCI format 0_1 ​​or 0_2, the UE does not send PUSCH repetition in the slot.

[0089] In addition, PUSCH transmission of transport blocks on multiple time slots may be based on whether the time slot is considered available. The UE determines the NK time slots used for PUSCH transmission of TBs on multiple time slots scheduled by DCI format 0_1 ​​or 0_2 based on tdd-UL-DL-ConfigurationCommon, tdd-UL-DL-ConfigurationDedicated, UL and DL subband configurations and ssb-PositionsInBurst, as well as the TDRA information field value of DCI format 0_1 ​​or 0_2. If at least one of the symbols indicated by the index row of the resource allocation table used in the time slot overlaps with a DL symbol indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL ConfigurationDedicated (if there is no configured UL subband) or a symbol of an SS / PBCH block with an index provided by ssb-PositionsInBurst, then the time slot is not counted in the number of NK time slots used for PUSCH transmission of TBs on multiple time slots.

[0090] In some implementations, when an SBFD symbol accommodates all resource blocks that are repeated (in both the time and frequency domains) within the UL subband 440, the SBFD slot 420 is considered an available slot for the repetition of the physical UL channel. For example, the SBFD symbol 422 can accommodate all resource blocks that are repeated based on a starting resource block applicable to both non-SBFD symbols and SBFD symbols, a starting resource block specific to SBFD symbols, or both, and a certain number of resource blocks applicable to both non-SBFD symbols and SBFD symbols, a certain number of resource blocks specific to SBFD symbols, or both. In some implementations, the SBFD symbol 422 accommodates all resource blocks that are repeated based on a PRB configuration specific to the SBFD symbol. For example, the definition of available time slots in non-paired spectrum may apply to a certain number of PUCCH repetition time slots for PUCCH transmission, which repetition time slots start from the time slot indicated to the UE for HARQ-ACK reporting or from the time slot determined to be used for SR reporting or for CSI reporting, which time slot has: UL symbols, or flexible symbols that are not SS / PBCH block symbols provided as the first symbol by startingSymbolIndex, or DL ​​symbols with configured UL subbands, and equal to or greater than the number of consecutive UL symbols provided by nrofsymbols, flexible symbols that are not SS / PBCH block symbols, or DL ​​symbols with configured UL subbands starting from the first symbol; and consecutive PRBs available for PUCCH transmission that are greater than the value of the PRB of the PUCCH provided by startingPRB or secondHopPRB and nrofPRBs or after applying an offset.

[0091] Similarly, for PUSCH, if the UL subband 440 accommodates PUSCH FDRA, the SBFD time slot 420 may be considered available. For example, with repeated transmission (e.g., when AvailableSlotCounting is enabled and in the case of K>1), the available time slots may be defined based on tdd-UL-DLConfigurationCommon, tdd-UL-DL-ConfigurationDedicated, UL and DL subband configurations and ssb-PositionsInBurst, and the TDRA and FDRA information field values ​​of DCI format 0_1 ​​or 0_2. If at least one of the symbols indicated by the index row of the used resource allocation table in a timeslot overlaps with a DL symbol indicated by tdd-UL-DLConfigurationCommon or tdd-UL-DLConfigurationDedicated (if no UL subband is configured) or a symbol of an SS / PBCH block with an index provided by ssb-PositionsInBurst, then the timeslot is not counted in the number of NK timeslots used for PUSCH transmission of PUSCH repetition type A scheduled by DCI format 0_1 ​​or 0_2. If at least one of the PRBs indicated by the FDRA bit field within the UE's active UL BWP is outside the UL subband 440, then the timeslot is not counted in the number of NK timeslots used for PUSCH transmission of PUSCH repetition type A scheduled by DCI format 0_1 ​​or 0_2.

[0092] In addition, PUSCH transmission of transport blocks on multiple time slots may be based on whether the time slot is considered available. The UE determines the NK time slots used for PUSCH transmission of TBs on multiple time slots scheduled by DCI format 0_1 ​​or 0_2 based on tdd-UL-DL-ConfigurationCommon, tdd-UL-DL-ConfigurationDedicated, UL and DL subband configurations and ssb-PositionsInBurst, as well as the TDRA and FDRA information field values ​​of DCI format 0_1 ​​or 0_2. If at least one of the symbols indicated by the index row of the resource allocation table used in the time slot overlaps with a DL symbol indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL ConfigurationDedicated (if there is no configured UL subband) or a symbol of an SS / PBCH block with an index provided by ssb-PositionsInBurst, then the time slot is not counted in the number of NK time slots used for PUSCH transmission of TBs on multiple time slots. If at least one of the PRBs indicated by the FDRA bit field within the UE active UL BWP is outside the UL subband 440, the slot is not counted in the number of NK slots for PUSCH transmission handled by TBs on multiple slots scheduled by DCI format 0_1 ​​or 0_2.

[0093] In some implementations, when the first time slot used for transmission of a physical UL channel is a time slot configured with an SBFD symbol, the time slot configured with the SBFD symbol is considered an available time slot for repetition. That is, for a physical UL channel that starts transmission in an SBFD time slot 420, the UE 104 may also consider subsequent SBFD time slots 420 to be available time slots. In contrast, for a transmission that starts in an UL time slot 430, the SBFD time slot 420 may not be considered an available time slot. For example, the definition of available time slots in a non-paired spectrum for PUCCH repetition on SBFD symbols may apply to a certain number of PUCCH repetition time slots for PUCCH transmission, starting from the time slot indicated to the UE for HARQ-ACK reporting or starting from the time slot determined to be used for SR reporting or for CSI reporting, which time slot has: an SBFD symbol (DL symbol with configured UL subband) that is not an SS / PBCH block symbol provided by startingSymbolIndex as the first symbol, and consecutive SBFD symbols (DL symbols with configured UL subband) that are not SS / PBCH block symbols starting from the first symbol that are equal to or greater than the number of symbols provided by nrofsymbols.

[0094] In addition, PUSCH transmission based on random access message 3 of a random access response (RAR) grant may be based on whether a timeslot is considered available. The UE determines the NK timeslots used for PUSCH transmission of PUSCH repetition type A scheduled by a RAR UL grant based on tdd-UL-DL-ConfigurationCommon and ssb-PositionsInBurst, the UL and DL subband configurations, and the TDRA information field value in the RAR UL grant. If at least one of the symbols in a timeslot indicated by the index row of the resource allocation table used overlaps with a DL symbol indicated by tdd-UL-DL-ConfigurationCommon (if there is no configured UL subband) or a symbol of an SS / PBCH block with an index provided by ssb-PositionsInBurst, then the timeslot is not counted in the number of NK timeslots used for PUSCH transmission of PUSCH repetition type A scheduled by a RAR UL grant.

[0095] Inter-slot frequency hopping can include changing the frequency of transmissions at slot boundaries. Typically, PUCCH transmissions without duplication occur within a slot, and inter-slot frequency hopping is not invoked. PUSCH and PUCCH transmissions with duplication may invoke inter-slot frequency hopping. Similar to intra-slot frequency hopping, the frequency change may result in resources outside of the UL subband 440. In some implementations, inter-slot frequency hopping is disabled on SBFD symbols 422.

[0096] In some implementations, the UE 104 may adjust the first PRB of a resource in a slot configured with SBFD symbols to transmit a physical UL channel using inter-slot frequency hopping. For example, the UE may adapt the resource for inter-slot frequency hopping by applying the same offset to both the starting PRB and the second hop PRB of the resource. In some implementations, the UE 104 may adapt the resource for inter-slot frequency hopping by applying a first offset to the starting PRB of the resource and a second offset to the second hop PRB. In some implementations, the UE is configured with a starting PRB and a second hop PRB specific to SBFD symbols, and inter-slot frequency hopping is enabled on slots that include SBFD symbols. In some implementations, the UE is configured with a list of starting PRBs, second hop PRBs, and a number of resource blocks, the list including at least a first set of values ​​applicable to non-SBFD symbols and a second set of values ​​applicable to SBFD symbols. In some implementations, the physical UL channel is scheduled or activated by a DCI 650 indicating the selected second hop PRB for the physical UL channel within the UL subband 440. In some implementations, the resources on the SBFD time slot 420 are configured with a starting symbol and a certain number of symbols specific to the SBFD symbol 422 .

[0097] Figure 7 7 is a conceptual data flow diagram 700 illustrating the flow of data between different elements / components in an example base station 702, which can be an example of a base station 102 including an SBFD scheduling component 120. The SBFD scheduling component 120 includes a UL configuration component 122, an indication sending component 124, and a UL receiving component 126. The SBFD scheduling component 120 can optionally include an adaptation component 710, a frequency hopping component 720, and / or a repetition component 730.

[0098] Base station 702 may include a receiver component 750 and a transmitter component 752. Receiver component 750 may include, for example, an RF receiver for receiving the signals described herein. Transmitter component 752 may include, for example, an RF transmitter for transmitting the signals described herein. In some implementations, receiver component 750 and transmitter component 752 may be co-located in a transceiver (such as a Figure 3 in Tx / Rx 318).

[0099] Receiver component 750 can receive UL signals from one or more UEs 104. For example, receiver component 750 can receive UE capabilities 610, physical UL channels 660, and / or repetitions 670. Receiver component 750 can provide UE capabilities 610 to UL configuration component 122. Receiver component 750 can provide physical UL channels 660 and / or repetitions 670 to UL reception component 126.

[0100] UL configuration component 122 may be configured to send a physical UL channel configuration 622 to UE 104. UL configuration component 122 may receive capabilities 610 for the UE via receiver component 750. For example, capabilities 610 may indicate capabilities for SBFD. UL configuration component 122 may determine that UE 104 is configured to transmit a physical UL channel, such as a PUCCH or PUSCH, on SBFD symbols. UL configuration component 122 may generate physical UL channel configuration 622. Physical UL channel configuration 622 may apply to both SBFD symbols 422 and non-SBFD symbols 424. In some implementations, physical UL channel configuration 622 may include one or more parameters specific to SBFD symbols 422. UL configuration component 122 may send physical UL channel configuration 622 to UE 104 via transmitter component 752.

[0101] The indication Tx component 124 may be configured to transmit an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol. For example, the indication Tx component 124 may receive an indication of a transmission size and other transmission parameters from a higher-layer scheduler. For example, the transmission size may be based on a scheduling request from the UE 104. The indication Tx component 124 may determine a certain number of RBs to be used for transmission. The indication Tx component 124 may select RBs for transmission based on the PUCCH resource set 632 or the resources 642. The selected resources may include SBFD symbols. The indication Tx component 124 may generate DCI 650 to indicate the selected resources. The indication Tx component 124 may transmit the DCI 650 via the transmitter component 752. The indication Tx component 124 may also indicate the selected resources to the UL receive component 126.

[0102] In some implementations, SBFD scheduling component 120 can optionally include one or more of adaptation component 710, frequency hopping component 720, or repetition component 730, each of which can receive an indication of resources for transmission.

[0103] The adapting component 710 can be configured to adapt the resources to accommodate all resource blocks of the physical UL channel within the UL subband. For example, the adapting component 710 can determine whether resources outside the UL subband 440 can be adapted based on the offset or SBFD specific parameters as discussed above. The adapting component 710 can output the adapted resources to the UL receiving component 126.

[0104] Frequency hopping component 720 can be configured to determine whether to apply intra-slot frequency hopping or inter-slot frequency hopping to the physical UL channel. For example, frequency hopping component 720 can evaluate frequency hopping parameters 636 or 644 to determine whether the second hop will be within UL sub-band 440. Frequency hopping component 720 can disable frequency hopping or adapt the frequency hopping parameters to use RBs within UL sub-band 440. Frequency hopping component 720 can output the resources after taking frequency hopping into account to UL receiving component 126.

[0105] The repetition component 730 can determine whether the physical UL channel is repeated on an available time slot. For example, the repetition component 730 can determine whether the SBFD time slot 420 is considered an available time slot for repetition based on the resources received from the indication Tx component 124. The repetition component 730 can output additional resources for repetition to the UL receive component 126.

[0106] The UL receive component 126 can be configured to determine whether the UE 104 transmits the physical UL channel on the resource based on whether all resource blocks of the physical UL channel are within the UL subband. For example, the UL receive component 126 can receive the resource output by the indication Tx component 124 or the adapted, modified, or additional resource determined by the adaptation component 710, the frequency hopping component 720, or the repetition component 730. If the resource is within the UL subband 440, the UL receive component 126 can determine that the UE 104 transmits the physical UL channel on the resource. The UL receive component 126 can receive the physical UL channel on the SBFD symbol 422 within the UL subband 440.

[0107] Figure 8 is a conceptual data flow diagram 800 illustrating the flow of data between different parts / components in an example UE 804 , which may be an example of UE 104 and includes SBFD component 140 .

[0108] As about Figure 1 As discussed, SBFD component 140 can include configuration component 142, resource component 144, and transmission component 146. SBFD scheduling component 120 can optionally include adaptation component 710, frequency hopping component 720, and / or repetition component 730.

[0109] UE 104 may also include a receiver component 870 and a transmitter component 872. Receiver component 870 may include, for example, an RF receiver for receiving the signals described herein. Transmitter component 872 may include, for example, an RF transmitter for transmitting the signals described herein. In some implementations, receiver component 870 and transmitter component 872 may be co-located in a transceiver.

[0110] Receiver component 870 can receive DL signals such as RRC signaling 620, physical UL channel configuration 622, and RRC signaling 620 and DCI 650. Receiver component 870 can provide RRC signaling 620 to configuration component 142. Receiver component 870 can provide DCI 650 to resource component 144.

[0111] Configuration component 142 is configured to receive a physical UL channel configuration 622. For example, configuration component 142 may receive RRC signaling 620 via receiver component 870. Configuration component 142 may extract physical UL channel configuration 622 from RRC signaling 620, for example, by decoding the RRC signaling. For example, configuration component 142 may extract parameters of PUCCH configuration 630 or PUSCH configuration 640. Physical UL channel configuration 622 may apply to both SBFD symbols 422 and non-SBFD symbols 424. In some implementations, physical UL channel configuration 622 may include one or more parameters specific to SBFD symbols 422. Parameters (e.g., PUCCH resource set 632 or resources 642) may define available resources for transmitting the physical UL channel. Configuration component 142 may provide the configured resources to resource component 144.

[0112] Resource component 144 is configured to receive an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol. For example, resource component 144 may receive DCI 650 via receiver component 870. For example, resource component 144 may perform blind decoding to detect the DCI format. DCI 650 may include one or more fields, such as PRI 652 or FDRA 654 and TDRA 656, that allocate resources for a physical UL channel. Resource component 144 may output the indicated resources to transmit component 146.

[0113] In some implementations, SBFD component 140 can optionally include one or more of an adaptation component 810, a frequency hopping component 820, or a repetition component 830, each of which can receive the indicated resources for transmission from resource component 144. Adaptation component 810, frequency hopping component 820, and repetition component 830 can be similar to the corresponding adaptation component 710, frequency hopping component 720, or repetition component 730 at base station 702. Thus, SBFD component 140 can adapt the indicated resources in the same manner as SBFD scheduling component 120 so that base station 102 and UE 104 agree on the resources for the UL physical channel.

[0114] The adapting component 810 can be configured to adapt the resources to accommodate all resource blocks of the physical UL channel within the UL subband. For example, the adapting component 810 can determine whether resources outside the UL subband 440 can be adapted based on the offset or SBFD specific parameters as discussed above. The adapting component 810 can output the adapted resources to the transmitting component 146.

[0115] Frequency hopping component 820 can be configured to determine whether to apply intra-slot frequency hopping or inter-slot frequency hopping to the physical UL channel. For example, frequency hopping component 820 can evaluate frequency hopping parameters 636 or 644 to determine whether the second hop will be within UL sub-band 440. Frequency hopping component 820 can disable frequency hopping or adapt the frequency hopping parameters to use RBs within UL sub-band 440. Frequency hopping component 820 can output the resources after taking frequency hopping into account to transmitting component 146.

[0116] Repeat component 830 can determine whether the physical UL channel is repeated on an available time slot. For example, repeat component 830 can determine whether SBFD time slot 420 is considered an available time slot for repetition based on the resources received from resource component 144. Repeat component 830 can output additional resources for repetition to transmission component 146.

[0117] The transmitting component 146 can be configured to determine whether to transmit the physical UL channel on the resource based on whether all resource blocks of the physical UL channel are within the UL subband. In some implementations, when all resource blocks of the physical UL channel are not within the UL subband, the transmitting component 146 can discard (e.g., not transmit) the physical UL channel. When the adapting component 810, the frequency hopping component 820, or the repeating component 830 adapts the resource to accommodate all resource blocks of the physical UL channel within the UL subband 440, the transmitting component 146 can transmit the physical UL channel on the adapted resource. The transmitting component 146 can output the UL physical channel for transmission on the SBFD symbol 422 within the UL subband 440.

[0118] Figure 9 9 is a flow chart of an example method 900 for a UE to transmit a physical UL channel on SBFD symbols. Method 900 may be performed by a UE (such as UE 104, which may include memory 360 and may be the entire UE 104 or a component of UE 104, such as SBFD component 140, Tx processor 368, Rx processor 356, or controller / processor 359). Method 900 may be performed by SBFD component 140 in communication with SBFD scheduling component 120 of base station 102. Optional boxes are shown with dashed lines.

[0119] At block 910, method 900 includes receiving a configuration of a physical UL channel, the configuration applicable to both SBFD symbols and non-SBFD symbols. In some implementations, for example, the UE 104, the Rx processor 356, or the controller / processor 359 may execute the SBFD component 140 or the configuration component 142 to receive the physical UL channel configuration 622. The physical UL channel configuration 622 applies to both SBFD symbols 422 and non-SBFD symbols 424. Thus, the UE 104, the Rx processor 356, or the controller / processor 359 executing the SBFD component 140 or the configuration component 142 may provide means for receiving a configuration of a physical UL channel, the configuration applicable to both SBFD symbols and non-SBFD symbols.

[0120] At block 920, method 900 includes receiving an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol. In some implementations, for example, the UE 104, the Rx processor 356, or the controller / processor 359 may execute the SBFD component 140 or the resource component 144 to receive DCI 650 that includes an indication of resources (e.g., PRI 652, FDRA 654, or TDRA 656) to be used for transmission on at least one time slot 420 configured with the SBFD symbol. Thus, the UE 104, the Rx processor 356, or the controller / processor 359 executing the SBFD component 140 or the resource component 144 may provide means for receiving an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol.

[0121] At block 930, method 900 includes determining whether to transmit the physical UL channel on the resource based on whether all resource blocks of the physical UL channel are within the UL subband. In some implementations, for example, the UE 104, Tx processor 368, or controller / processor 359 may execute the SBFD component 140 and / or the transmit component 146 to determine whether to transmit the physical UL channel on the resource based on whether all resource blocks of the physical UL channel are within the UL subband 440. For example, at subblock 932, block 930 may optionally include discarding the physical UL channel when all resource blocks of the physical UL channel are not within the UL subband. For another example, at subblock 934, block 930 may optionally include adapting the resource to accommodate all resource blocks of the physical UL channel within the UL subband. Thus, the UE 104, Tx processor 368, or controller / processor 359 executing SBFD component 140 or transmit component 146 may provide means for determining whether to transmit the physical UL channel on the resources based on whether all resource blocks of the physical UL channel are within the UL subband.

[0122] At block 940, method 900 may optionally include determining whether to transmit the physical UL channel using intra-time slot frequency hopping. In some implementations, for example, the UE 104, Tx processor 368, or controller / processor 359 may execute the SBFD component 140 and / or the frequency hopping component 820 to determine whether to transmit the physical UL channel using intra-time slot frequency hopping. Thus, the UE 104, Tx processor 368, or controller / processor 359 executing the SBFD component 140 or the frequency hopping component 820 may provide means for determining whether to transmit the physical UL channel using intra-time slot frequency hopping.

[0123] At block 950, the method 900 can optionally determine whether to transmit the physical UL channel on the time slot configured with the SBFD symbol using a configured number of repetitions or an indicated number of repetitions based on whether the time slot configured with the SBFD symbol is considered an available time slot for repetition. In some implementations, for example, the UE 104, the Tx processor 368, or the controller / processor 359 can execute the SBFD component 140 and / or the repetition component 830 to determine whether to transmit the physical UL channel on the time slot configured with the SBFD symbol using a configured number of repetitions or an indicated number of repetitions based on whether the time slot configured with the SBFD symbol is considered an available time slot for repetition. Thus, the UE 104, Tx processor 368, or controller / processor 359 executing the SBFD component 140 or repetition component 830 may provide means for determining whether to transmit the physical UL channel on the time slot configured with the SBFD symbol using the configured number of repetitions or the indicated number of repetitions based on whether the time slot configured with the SBFD symbol is deemed an available time slot for repetition.

[0124] At block 960, method 900 can optionally determine whether to transmit the physical UL channel on the time slot in which the SBFD symbol is configured using the configured number of repetitions or the indicated number of repetitions based on whether the time slot in which the SBFD symbol is configured is deemed an available time slot for repetition. In some implementations, for example, the UE 104, Tx processor 368, or controller / processor 359 can execute the SBFD component 140 and / or the frequency hopping component 820 to determine whether to transmit the physical UL channel on one or more time slots in which the SBFD symbol is configured using the configured number of repetitions and inter-slot frequency hopping or using the indicated number of repetitions and inter-slot frequency hopping. Thus, the UE 104, Tx processor 368, or controller / processor 359 executing the SBFD component 140 or the frequency hopping component 820 can provide means for determining whether to transmit the physical UL channel on one or more time slots in which the SBFD symbol is configured using the configured number of repetitions and inter-slot frequency hopping or using the indicated number of repetitions and inter-slot frequency hopping.

[0125] At block 970, method 900 may optionally include transmitting the physical UL channel on the resource on the SBFD symbol within the UL subband. In some implementations, for example, the UE 104, Tx processor 368, or controller / processor 359 may execute the SBFD component 140 or transmitter component 872 to transmit the physical UL channel 660 or repetition 670 on the resource (e.g., SBFD UL RB 406) on the SBFD symbol 422 within the UL subband 440. Thus, the UE 104, Tx processor 368, or controller / processor 359 executing the SBFD component 140 or transmitter component 872 may provide means for transmitting the physical UL channel on the resource on the SBFD symbol within the UL subband.

[0126] Figure 10 1 is a flow chart of an example method 1000 for a base station to receive an UL signal from a UE on SBFD symbols. Method 1000 may be performed by a base station (such as base station 102, which may include memory 376 and may be the entire base station 102 or a component of base station 102, such as SBFD scheduling component 120, Tx processor 316, Rx processor 370, or controller / processor 375). Method 1000 may be performed by SBFD scheduling component 120 in communication with SBFD component 140 of first UE 104. Optional boxes are shown with dashed lines.

[0127] At block 1010, method 1000 includes sending a configuration of a physical UL channel to a UE, the configuration applicable to both SBFD symbols and non-SBFD symbols. In some implementations, for example, base station 102, Tx processor 316, or controller / processor 375 may execute SBFD scheduling component 120 or UL configuration component 122 to send physical UL channel configuration 622 to UE 104. Physical UL channel configuration 622 applies to both SBFD symbols 422 and non-SBFD symbols 424. Thus, base station 102, Tx processor 316, or controller / processor 375 executing SBFD scheduling component 120 or UL configuration component 122 may provide means for sending a configuration of a physical UL channel to a UE, the configuration applicable to both SBFD symbols and non-SBFD symbols.

[0128] At block 1020, method 1000 includes sending an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol. In some implementations, for example, base station 102, Tx processor 316, or controller / processor 375 may execute SBFD scheduling component 120 or instruct Tx component 124 to send an indication (e.g., DCI 650) of resources to be used for transmission on at least one time slot 420 configured with the SBFD symbol 422. Thus, base station 102, Tx processor 316, or controller / processor 375 executing SBFD scheduling component 120 or instructing Tx component 124 may provide means for sending an indication of resources to be used for transmission on at least one time slot configured with the SBFD symbol.

[0129] At block 1030, method 1000 includes determining whether the UE should transmit the physical UL channel on the resource based on whether all resource blocks of the physical UL channel are within the UL subband. In some implementations, for example, base station 102, Rx processor 370, or controller / processor 375 may execute SBFD scheduling component 120 or UL reception component 126 to determine whether the UE 104 should transmit the physical UL channel 660 on the resource based on whether all resource blocks of the physical UL channel 660 are within the UL subband 440. For example, at subblock 1032, block 1030 may optionally include discarding (e.g., not receiving) the physical UL channel when all resource blocks of the physical UL channel are not within the UL subband. For another example, at subblock 1034, block 1030 may optionally include adapting the resource to accommodate all resource blocks of the physical UL channel within the UL subband. Thus, the base station 102, the Rx processor 370, or the controller / processor 375 executing the SBFD scheduling component 120 or the UL reception component 126 may provide means for determining whether the UE transmits the physical UL channel on the resources based on whether all resource blocks of the physical UL channel are within the UL subband.

[0130] At block 1040, method 1000 may optionally include determining whether to transmit the physical UL channel using intra-time slot frequency hopping. In some implementations, for example, base station 102, Rx processor 370, or controller / processor 375 may execute SBFD scheduling component 120 or frequency hopping component 720 to determine whether to transmit the physical UL channel using intra-time slot frequency hopping. Thus, base station 102, Rx processor 370, or controller / processor 375 executing SBFD scheduling component 120 or frequency hopping component 720 may provide means for determining whether to transmit the physical UL channel using intra-time slot frequency hopping.

[0131] At block 1050, method 1000 may optionally include determining whether to transmit the physical UL channel in the time slot in which the SBFD symbol is configured using a configured number of repetitions or an indicated number of repetitions based on whether the time slot in which the SBFD symbol is configured is considered an available time slot for repetition. In some implementations, for example, base station 102, Rx processor 370, or controller / processor 375 may execute SBFD scheduling component 120 or repetition component 730 to determine whether to transmit the physical UL channel in the time slot in which the SBFD symbol is configured using a configured number of repetitions or an indicated number of repetitions based on whether the time slot in which the SBFD symbol is configured is considered an available time slot for repetition. Thus, the base station 102, the Rx processor 370, or the controller / processor 375 executing the SBFD scheduling component 120 or the repetition component 730 may provide means for determining whether to transmit the physical UL channel on the time slot configured with the SBFD symbol using the configured number of repetitions or the indicated number of repetitions based on whether the time slot configured with the SBFD symbol is deemed an available time slot for repetition.

[0132] At block 1060, method 1000 may optionally include determining whether to transmit the physical UL channel in the one or more time slots configured with the SBFD symbol using a configured number of repetitions and inter-slot frequency hopping or an indicated number of repetitions and inter-slot frequency hopping. In some implementations, for example, the base station 102, the Rx processor 370, or the controller / processor 375 may execute the SBFD scheduling component 120 or the frequency hopping component 720 to determine whether to transmit the physical UL channel in the one or more time slots configured with the SBFD symbol using a configured number of repetitions and inter-slot frequency hopping or an indicated number of repetitions and inter-slot frequency hopping. Thus, the base station 102, the Rx processor 370, or the controller / processor 375 executing the SBFD scheduling component 120 or the frequency hopping component 820 may provide means for determining whether to transmit the physical UL channel in the one or more time slots configured with the SBFD symbol using a configured number of repetitions and inter-slot frequency hopping or an indicated number of repetitions and inter-slot frequency hopping.

[0133] At block 1070, method 1000 may optionally include receiving the physical UL channel on the resource on the SBFD symbol in the UL subband. In some implementations, for example, base station 102, Tx processor 316, or controller / processor 375 may execute SBFD scheduling component 120 or receiver component 750 to receive physical UL channel 660 or repetition 670 on the resource on the SBFD symbol 422 in the UL subband 440. Thus, base station 102, Tx processor 316, or controller / processor 375 executing SBFD scheduling component 120 or receiver component 750 may provide means for receiving the physical UL channel on the resource on the SBFD symbol in the UL subband.

[0134] The following provides an overview of various aspects of the disclosure:

[0135] Aspect 1.
