[0002] The present disclosure relates generally to communication systems, and more particularly to enhancements in collision resolution for overlapping uplink transmissions with different priorities. [Background technology]

[0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. A typical wireless communication system 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.

[0004] These multiple access technologies are being adopted in various telecommunications standards to provide common protocols that enable different wireless devices to communicate on a city, national, regional, or even global scale. An exemplary telecommunications standard is 5G New Radio (NR). 5G NR is part of the ongoing mobile broadband evolution promulgated by the 3rd Generation Partnership Project (3GPP®) to meet new requirements related to latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)), and other requirements. 5G NR includes services related to enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard.

[0005] There is a need for further improvements in 5G NR technology, such as with regard to improving efficiency in transmitting data. These improvements may also be applicable to other multiple access technologies and telecommunications standards that employ these technologies.

[0021] The detailed description set forth below with reference to the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing 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 instances, well-known structures and components are shown in block diagram form to avoid obscuring such concepts.

[0022] This aspect generally relates to collision resolution for overlapping uplink transmissions with different priorities. For example, in New Radio (NR) Release 15, when two uplink transmissions overlap in time (i.e., overlap in at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol within a slot) and at least one of the uplink transmissions is a Physical Uplink Control Channel (PUCCH) with repetition (e.g., a multi-slot PUCCH), a user equipment (UE) that is scheduled for an uplink transmission may drop one of the uplink transmissions according to the following order of priority (in descending order): Hybrid Access Request (HARQ) Acknowledgment (ACK), Scheduling Request (SR), High-Priority Channel State Information (CSI), Low-Priority CSI, and Physical Uplink Shared Channel (PUSCH).

[0023] In one aspect, in NR Release 16, when multiple uplink transmissions with different priorities overlap in time, the UE may cancel the low-priority uplink transmission and transmit only the high-priority uplink transmission. For example, the priority refers to a priority index configured for each uplink channel (e.g., in Release 16, the priority index can be either 0 or 1, where 1 corresponds to high priority and 0 corresponds to low priority). However, if at least one of the uplink transmissions is an uplink transmission with repetition, an extension is needed to resolve collisions between overlapping uplink transmissions with different priorities.

[0024] In particular, the present disclosure relates to extending collision resolution for overlapping uplink transmissions with different priorities. For example, two or more scheduled uplink transmissions with different priorities may overlap in at least one slot. Therefore, it is desirable for a UE to perform collision resolution procedures between overlapping uplink transmissions with different priorities when at least one of the uplink transmissions is an uplink transmission with repetition.

[0025]

[0010] Accordingly, the present disclosure provides an apparatus and method in a UE for identifying two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, where at least one of the two or more uplink transmissions is scheduled for repeated transmission across at least a first slot and a second slot, and performing one or more collision resolution procedures in at least one of the first slot and the second slot for the two or more scheduled uplink transmissions with different priorities that overlap in the at least one slot to resolve a collision for at least one of one or more low-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions and one or more high-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions.

[0026] In another aspect, the present disclosure provides an apparatus and method in a UE for identifying two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, where at least one of the two or more uplink transmissions comprises a low priority uplink transmission scheduled for repeated transmission across at least a first slot and a second slot, and further comprises one or more high priority uplink transmissions scheduled in the first slot; performing one or more collision resolution procedures in the first slot to resolve a collision of the low priority uplink transmission with the one or more high priority uplink transmissions scheduled in the first slot by canceling the low priority uplink transmission scheduled in the first slot; and transmitting a low priority uplink transmission scheduled in the second slot in response to the low priority uplink transmission that does not overlap with any transmission of the two or more scheduled uplink transmissions with different priorities that overlap in the at least one slot.

[0027] In another aspect, the present disclosure provides an apparatus and method in a UE for identifying multiple scheduled uplink transmissions that overlap in at least a first slot and a second slot, the multiple uplink transmissions comprising a first high priority uplink transmission scheduled for repeated transmissions across at least the first slot and the second slot, and further comprising one or more additional uplink transmissions scheduled in the first slot and two or more additional uplink transmissions scheduled in the second slot, the two or more additional uplink transmissions scheduled in the second slot comprising at least a low priority uplink transmission and a second high priority uplink transmission; and performing a first collision resolution procedure in the first slot and a second collision resolution procedure in the second slot, wherein the second collision resolution procedure is independent of the first collision resolution procedure.

[0028] Thus, aspects described herein enable efficient resolution of overlapping scheduled uplink transmissions with different priorities.

[0029] These and other features of the present disclosure are described in detail below with respect to FIGS.

[0030] Several aspects of telecommunications systems are now presented with reference to various apparatus and methods. These apparatus and methods are described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0031] As an example, an element or any portion of an element or any combination of elements may be implemented as a "processing system" including one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems-on-chips (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gate logic, discrete hardware circuits, and other suitable hardware configured to perform various functions described throughout this disclosure. One or more processors in a processing system may execute software. Software may be broadly interpreted to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0032] Thus, in one or more exemplary embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media include computer storage media. A storage medium may be any available medium that can be accessed by a computer. By way of example, and not limitation, such computer-readable media may comprise random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the above 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.

[0033] 1 illustrates an example of a wireless communication system 100. The wireless communication system (also referred to 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 190 (e.g., 5G core (5GC)).

[0034] In some aspects, each UE 104 may include a UE communication component 121 for performing collision resolution for overlapping uplink transmissions with different priorities. The UE 104 may have an access link 120 directly with the base station 102. The UE communication component 121 of the UE 104 may be selectively configured to schedule multiple uplink transmissions with different priorities and to perform collision resolution for overlapping uplink transmissions with different priorities.

[0035] Similarly, the base station 102 may include a base station communication component 127 configured to receive uplink transmissions from the UE 104 on one or more uplink channels, as described herein.

[0036] Further details of these operations performed by the UE 104 and the base station 102 are described in more detail below.

[0037] The base stations 102 may include macrocells (high-power cellular base stations) and / or small cells (low-power cellular base stations). Macrocells include base stations. Small cells include femtocells, picocells, and microcells.

[0038] A base station 102 configured for 4G LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 through a backhaul link 132 (e.g., an S1 interface). A base station 102 configured for 5G NR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with the 5G core network 190 through a backhaul link 184. In addition to other functions, the base station 102 may perform one or more of the following functions: transfer 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 setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast services (MBMS), subscriber and equipment tracing, RAN information management (RIM), paging, positioning, and delivery of alert messages. The base stations 102 may communicate with each other directly or indirectly (e.g., through the EPC 160 or the core network 190) over backhaul links 134 (e.g., X2 interfaces). The backhaul links 134 may be wired or wireless.

[0039] The base stations 102 may communicate wirelessly with the UE 104. Each of the base stations 102 may provide communication coverage in a respective geographic coverage area 110. Overlapping geographic coverage areas 110 may exist. For example, a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including both small cells and macro cells may be referred to as a heterogeneous network. A heterogeneous network may also include a Home Evolved Node B (eNB) (HeNB) that may serve a closed group known as a Closed Subscriber Group (CSG). The communication link 120 between the base station 102 and the UE 104, including access links 120a and 120b, may include uplink (UL) (also referred to as reverse link) transmissions from the UE 104 to the base station 102 and / or downlink (DL) (also referred to as forward link) transmissions from the base station 102 to the UE 104. The communication link 120 may use multiple-input multiple-output (MIMO) antenna techniques, including spatial multiplexing, beamforming, and / or transmit diversity. The communication link may be over one or more carriers. The base station 102 / UE 104 may use spectrum with a bandwidth of up to Y MHz per carrier (e.g., 5, 10, 15, 20, 100, 400 MHz, etc.) allocated in carrier aggregation with up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. The carrier allocation may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​than for UL). The 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 a secondary cell (SCell).

[0040] Several UEs 104 may communicate with each other using device-to-device (D2D) communication links 158, an example of which includes a sidelink 158a. The D2D communication links 158 may use 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), and a physical sidelink control channel (PSCCH). The D2D communication may be through various wireless D2D communication systems, such as FlashLinQ, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0041] The wireless communication system may further include a Wi-Fi access point (AP) 150 communicating with a Wi-Fi station (STA) 152 via a communication link 154 in the 5 GHz unlicensed frequency spectrum. When communicating in the unlicensed frequency spectrum, the STA 152 / AP 150 may perform clear channel assessment (CCA) prior to communicating to determine if a channel is available.

[0042] The small cell 102' may operate in licensed and / or unlicensed frequency spectrum. When operating in the unlicensed frequency spectrum, the small cell 102' may employ NR and use the same 5 GHz unlicensed frequency spectrum used by the Wi-Fi AP 150. A small cell 102' employing NR in the unlicensed frequency spectrum may extend coverage to and / or increase capacity of the access network.

[0043] The 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 another type of base station. Some base stations, such as the gNB 180, communicate with the UE 104 and may operate in the traditional sub-6 GHz spectrum, millimeter wave (mmW) frequencies, and / or sub-mmW frequencies. When the gNB 180 operates in mmW or sub-mmW frequencies, it may be referred to as an mmW base station. Extremely high frequency (EHF) is the RF portion of the electromagnetic spectrum. The electromagnetic spectrum is often subdivided into various classes, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified, designated frequency ranges FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although portions of FR1 are greater than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. Similar nomenclature issues arise with FR2, which is often referred to (interchangeably) as the "millimeter wave" band in documents and papers, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the "millimeter wave" band by the International Telecommunications Union (ITU).

[0044] With the above aspects in mind, it should be understood that unless otherwise specified, terms such as "sub-6 GHz," when used herein, may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, it should be understood that unless otherwise specified, terms such as "millimeter wave," when used herein, may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

[0045] The base station 180 may transmit beamformed signals to the UE 104 in one or more transmit directions 182′. The UE 104 may receive beamformed signals from the base station 180 in one or more receive directions 182″. The UE 104 may also transmit beamformed signals to the base station 180 in one or more transmit directions. The base station 180 may receive beamformed signals from the UE 104 in one or more receive directions. The base station 180 / UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 180 / UE 104. The transmit and receive directions for the base station 180 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.

[0046] The 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. The MME 162 may be in communication with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are forwarded through the serving gateway 166, which is itself connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation and other functions. The PDN gateway 172 and the BM-SC 170 are connected to the IP services 176. The IP services 176 may include the Internet, intranets, IP Multimedia Subsystem (IMS), packet-switched (PS) streaming services, and / or other IP services. The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmissions, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and may be used to schedule MBMS transmissions. The MBMS gateway 168 may be used to distribute MBMS traffic to base stations 102 belonging to a multicast broadcast single frequency network (MBSFN) area that broadcasts a particular service, and may be responsible for session management (start / stop) and collecting eMBMS-related charging information.

[0047] The core network 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. The AMF 192 may be in communication with a Unified Data Management (UDM) 196. The AMF 192 is a control node that handles signaling between the UE 104 and the core network 190. Generally, the AMF 192 provides QoS flow and session management. All user Internet Protocol (IP) packets are forwarded through the UPF 195. The UPF 195 provides UE IP address allocation and other functions. The UPF 195 is connected to IP services 197. The IP services 197 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), PS streaming services, and / or other IP services.

[0048] 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. The base station 102 provides an access point to the EPC 160 or core network 190 for the UE 104. Examples of the 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 cooking appliance, a health management device, an implant, a sensor / actuator, a display, or any other similarly functional device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). The UE 104 may also be referred to as a station, mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable terminology.

[0049] 2A-2D include diagrams of example frame structures and resources that may be utilized in communications between a base station 102 and a UE 104 described in this disclosure. FIG. 2A is a diagram 200 illustrating an example of a first subframe in a 5G / NR frame structure. FIG. 2B is a diagram 230 illustrating an example of a DL channel in a 5G / NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe in a 5G / NR frame structure. FIG. 2D is a diagram 280 illustrating an example of a UL channel in a 5G / NR subframe. The 5G / NR frame structure may be frequency domain duplex (FDD) where, for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated to either DL or UL, or time domain duplex (TDD) where, for a particular set of subcarriers (carrier system bandwidth), subframes within the set of subcarriers are dedicated to both DL and UL. In the examples given by Figures 2A and 2C, the 5G / NR frame structure is assumed to be TDD, subframe 4 is configured with slot format 28 (mostly DL), where D is DL, U is UL, and X is flexible for use between DL and UL, and subframe 3 is configured with slot format 34 (mostly UL). Subframes 3 and 4 are shown with slot formats 34 and 28, respectively, but any particular subframe may be configured with any of the various available slot formats 0 through 61. Slot formats 0 and 1 are all DL and UL, respectively. The other slot formats 2 through 61 include a mix of DL, UL, and flexible symbols. The UE is configured with a slot format through a received slot format indicator (SFI) (either dynamically through DL control information (DCI) or semi-statically / statically through radio resource control (RRC) signaling). Note that the following description also applies to 5G / NR frame structures that are TDD.

[0050] Other wireless communication technologies may have different frame structures and / or different channels. A frame (10 ms) may be divided into 10 equal-sized subframes (1 ms). Each subframe may include one or more time slots. A subframe may also include a minislot, which may include 7, 4, or 2 symbols. Each slot may include 7 or 14 symbols depending on the slot configuration. For slot configuration 0, each slot may include 14 symbols, and for slot configuration 1, each slot may include 7 symbols. Symbols on the DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. 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 called single-carrier frequency division multiple access (SC-FDMA) symbols) (for power-limited scenarios and limited to single-stream transmission). The number of slots in a subframe is based on the slot configuration and numerology. For slot configuration 0, the different numerologies μ 0-5 allow 1, 2, 4, 8, 16, and 32 slots per subframe, respectively. For slot configuration 1, the different numerologies 0-2 allow 2, 4, and 8 slots per subframe, respectively. Thus, for slot configuration 0 and numerology μ, 14 symbols / slot and 2 μ There are slots / subframes. Subcarrier spacing and symbol length / duration are functions of numerology. Subcarrier spacing is 2 μ * may be equal to 15 kHz, where μ is a numerology from 0 to 5. Thus, numerology μ=0 has a subcarrier spacing of 15 kHz, and numerology μ=5 has a subcarrier spacing of 480 kHz. Symbol length / duration is inversely related to subcarrier spacing. Figures 2A-2D give an example of slot configuration 0 with 14 symbols per slot and numerology μ=0 with 1 slot per subframe. The subcarrier spacing is 15 kHz, and the symbol duration is approximately 66.7 μs.

[0051] A resource grid can be used to represent the frame structure. Each time slot contains a resource block (RB) (also called a physical RB (PRB)) that spans 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (RE). The number of bits carried by each RE depends on the modulation scheme.

[0052] As shown in FIG. 2A, some of the REs carry reference (pilot) signals (RS) for the UE. The RSs are demodulated RSs (DM-RSs) (for one particular configuration, 100x is the port number) for channel estimation at the UE. x , but other DM-RS configurations are possible), and channel state information reference signals (CSI-RS). The RSs may also include beam measurement RSs (BRS), beam improvement RSs (BRRS), and phase tracking RSs (PT-RS).

[0053] FIG. 2B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each containing nine RE groups (REGs), with each REG containing four consecutive REs within an OFDM symbol. A primary synchronization signal (PSS) may be within symbol 2 of a particular subframe of the frame. The PSS is used by the UE 104 to determine subframe / symbol timing and physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of a particular subframe of the frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS described above. The Physical Broadcast Channel (PBCH), which carries the Master Information Block (MIB), may be logically grouped with the PSS and SSS to form the Synchronization Signal (SS) / PBCH block. The MIB provides the number of RBs in the system bandwidth and the System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information not transmitted over the PBCH, such as System Information Blocks (SIBs), and paging messages.

[0054] As shown in Figure 2C, some of the REs carry DM-RS (denoted as R for one particular configuration, although other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH). The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether a short or long PUCCH is transmitted and the particular PUCCH format used. 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 on the UL.

[0055] 2D shows an example of various UL channels within a subframe of a frame. In one configuration, the PUCCH may be located as shown. The PUCCH carries uplink control information (UCI) such as scheduling requests, channel quality indicators (CQIs), precoding matrix indicators (PMIs), rank indicators (RIs), and HARQ ACK / NACK feedback. The PUSCH carries data and may be further used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCIs.

[0056] 3 is a diagram of hardware components of exemplary transmit and / or receive (TX / RX) nodes 310 and 350, which may be any combination of base station 102-UE 104 communication and / or UE 104-UE 104 communication in system 100. For example, such communication may include, but is not limited to, communication such as a base station transmitting to a UE, a UE transmitting to a second UE, a second UE transmitting to a UE, or a UE transmitting to a base station in a wireless communication system. In one particular example, TX / RX node 310 may be an exemplary implementation of a base station 102, and TX / RX node 350 may be an exemplary implementation of a UE 104. In the DL, IP packets from EPC 160 may be provided to controller / processor 375. Controller / processor 375 implements Layer 3 and Layer 2 functions. Layer 3 includes a Radio Resource Control (RRC) layer, and Layer 2 includes a Service Data Adaptation Protocol (SDAP) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Medium Access Control (MAC) layer. The controller / processor 375 provides RRC layer functions related to broadcasting system information (e.g., MIBs, SIBs), 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 functions related to header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functions related to transfer of upper layer packet data units (PDUs), error correction via ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions related to 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 via HARQ, priority handling, and logical channel prioritization.

[0057] The transmit (TX) processor 316 and receive (RX) processor 370 implement Layer 1 functions associated with various signal processing functions. Layer 1, including 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 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), M-quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to OFDM subcarriers, multiplexed with reference signals (e.g., pilots) in the time and / or frequency domains, and then combined together using an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain OFDM symbol stream. The OFDM stream is spatially precoded to generate multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme and for spatial processing. The channel estimates may be derived from a reference signal and / or channel condition feedback transmitted by the tx / rx node 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 the respective spatial stream for transmission.

[0058] In the TX / RX node 350, each receiver 354RX receives a signal through its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement Layer 1 functions associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the TX / RX node 350. When multiple spatial streams are destined for the TX / RX node 350, they may 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 comprises 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 TX / RX node 310. These soft decisions may be based on channel estimates calculated by a channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally transmitted by the TX / RX node 310 on the physical channel. The data and control signals are then provided to a controller / processor 359, which implements Layer 3 and Layer 2 functions.

[0059] 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 performs demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0060] Similar to the functionality described with respect to DL transmission by the TX / RX node 310, the controller / processor 359 provides RRC layer functions related to system information (e.g., MIB, SIB) collection, RRC connection, and measurement reporting; PDCP layer functions related to header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functions related to transfer of upper layer PDUs, error correction via ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functions related to mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction via HARQ, priority handling, and logical channel prioritization.

[0061] Channel estimates derived by the channel estimator 358 from a reference signal or feedback transmitted by the TX / RX node 310 may be used by the TX processor 368 to select an appropriate coding and modulation scheme and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a respective spatial stream for transmission.

[0062] UL transmissions are processed in the TX / RX node 310 in a manner similar to that described with respect to the receiver functions in the TX / RX node 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX recovers the information modulated onto the RF carrier and provides the information to the RX processor 370.

[0063] 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 performs demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the tx / rx node 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.

[0064] In one implementation in a UE, at least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to perform aspects associated with the UE communication component 121 of FIG.

[0065] In one implementation in a base station or network entity, at least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to perform aspects associated with the base station communication component 127 of FIG. 1.

[0066] Referring to Figure 4, a schematic diagram 400 illustrating an example of a transmission scheme for multiple uplink transmissions across multiple slots operable in the system of Figure 1 will be described. For example, a UE 104 and a base station 102 (e.g., a gNB) may communicate with each other, and in particular, the UE 104 may communicate to the base station 102 a first priority uplink transmission 410 and a second priority uplink transmission 420 in multiple slots. In some instances, the uplink transmission 410 may overlap with the uplink transmission 420 in one or more time slots.

[0067] In one aspect, when the UE 104 determines overlaps for physical uplink control channel (PUCCH) and / or physical uplink shared channel (PUSCH) transmissions of different priority indices, the UE 104 first resolves overlaps for PUCCH and / or PUSCH transmissions 420 of lower priority indices. Then, if a first PUCCH transmission 410 of a higher priority index scheduled by a downlink control information (DCI) format in a physical downlink control channel (PDCCH) reception would overlap in time with a second PUSCH or second PUCCH transmission 420 of a lower priority index, the UE 104 cancels the second PUSCH or second PUCCH transmission 420 before the first symbol in the slot that would overlap with the first PUCCH transmission 410. In another example, if a first PUSCH transmission 410 of a higher priority index scheduled by a DCI format in a PDCCH reception would overlap in time with a second PUCCH transmission 420 of a lower priority index, the UE 104 cancels the second PUCCH transmission 420 before the first symbol that would overlap with the first PUSCH transmission 410, where the overlap can be applied before or after resolving the overlap between channels of higher priority index. In this aspect, if a high priority transmission (that cancels a low priority transmission) is not scheduled by a DCI format in a PDCCH reception, the cancellation order specified above does not apply.

[0068] 5, a schematic diagram 500 illustrating an example of a cancellation order for multiple scheduled uplink transmissions overlapping over a single slot operable in the system of FIG. 1 will be described. For example, a UE 104 and a base station 102 (e.g., a gNB) may communicate with each other, and in particular, the UE 104 may communicate uplink transmissions of different priorities in a single slot to the base station 102. In some instances, multiple uplink transmissions may overlap in a single slot. A high priority transmission corresponds to a transmission with a priority index of 1, and a low priority transmission corresponds to a transmission with a priority index of 0.

[0069] In one aspect, the UE 104 schedules a high-priority (HP) HARQ-ACK transmission that overlaps with a low-priority (LP) PUCCH or PUSCH transmission via a first DCI (DCI1). The UE 104 then receives a second DCI (DCI2) that schedules a high-priority PUSCH that does not overlap with the low-priority PUCCH or PUSCH transmission. The UE 104 may multiplex the high-priority HARQ-ACK along with the high-priority PUSCH. In one example, if all transmissions are scheduled simultaneously, the UE 104 may be able to first resolve the overlap between the high-priority transmissions, and then the UE 104 may not need to cancel the low-priority transmission because the resulting high-priority transmission (in this example, the PUSCH) does not overlap with the low-priority channel.

[0070] In one aspect, as long as the UE 104 receives at least one high-priority grant (e.g., DCI1), the UE 104 may need to resolve collisions, and the UE 104 may not have to wait for other high-priority grants. For example, at the time of reception of DCI1, the UE 104 is unaware of whether DCI2 will be transmitted by the base station 102. The UE 104 may cancel low-priority transmissions upon reception of the first high-priority DCI. The canceled PUCCH / PUSCH transmissions may not be resumed at a later point in time, even if the UE 104 discovers that the high-priority HARQ-ACK has been moved to another uplink channel.

[0071] Referring to Figure 6, a schematic diagram 600 illustrating an example of a cancellation order for multiple scheduled uplink transmissions overlapping over a single slot operable in the system of Figure 1 will be described. For example, a UE 104 and a base station 102 (e.g., a gNB) may communicate with each other, and in particular, the UE 104 may communicate uplink transmissions of different priorities in a single slot to the base station 102. In some instances, multiple uplink transmissions may overlap in a single slot.

[0072] In one aspect, the UE 104 is configured with a high-priority scheduling request (SR) transmission that overlaps with a low-priority PUCCH or PUSCH transmission. The UE 104 then receives a second DCI (e.g., DCI2) that schedules a high-priority PUSCH that does not overlap with the low-priority PUCCH or PUSCH transmission. The UE 104 may drop the high-priority SR and transmit the high-priority PUSCH.

[0073] In one aspect, at the time the UE 104 receives the high priority PUSCH, the UE 104 knows that the high priority SR will be canceled because it is not scheduled by the DCI format (i.e., configured instead via RRC). As a result, in this example, the UE 104 may cancel the high priority SR but may not cancel low priority PUCCH or PUSCH transmissions. Unlike the scheduling of the high priority HARQ-ACK in Figure 5, the high priority SR in Figure 6 is not scheduled by the DCI format in the PDCCH.

[0074] 7, a schematic diagram 700 illustrating an example of multiple uplink transmissions across multiple slots operable in the system of FIG. 1 will be described. For example, the UE 104 and the base station 102 (e.g., a gNB) may communicate with each other, and in particular, the UE 104 may schedule multiple uplink transmissions to communicate to the base station 102. The UE 104 may perform one or more collision resolution procedures in at least one of a first slot and a second slot for two or more scheduled uplink transmissions with different priorities that overlap in at least one slot to resolve a collision for at least one of one or more low priority scheduled uplink transmissions of the two or more scheduled uplink transmissions and one or more high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions.

[0075] In one aspect, the UE 104 may identify overlapping uplink transmissions with different priorities. For example, at least one of the overlapping uplink transmissions is scheduled with repetition (e.g., a multi-slot PUCCH or PUSCH transmission). If an overlap occurs without a repetitive scheduled transmission, the UE 104 may perform the collision resolution procedure described in FIG. 5.

[0076] Furthermore, the UE 104 may resolve collisions between low-priority scheduled uplink transmissions. That is, if none of the low-priority scheduled uplink transmissions are PUCCH transmissions with repetition, the UE 104 may multiplex all of the overlapping low-priority scheduled uplink transmissions. If at least one of the overlapping low-priority scheduled uplink transmissions is a PUCCH transmission with repetition, the UE 104 may drop the low-priority scheduled uplink transmissions based on the priority of the transmission type (e.g., in descending order: HARQ ACK, SR, high-priority CSI, low-priority CSI, and PUSCH). As a result of step 1, there are no overlapping low-priority scheduled transmissions in any of the multiple slots.

[0077] Thus, once the UE 104 has completed resolving collisions between low priority scheduled uplink transmissions, it may perform one or more collision resolution procedures for any remaining high priority scheduled uplink transmissions that may overlap.

[0078] In a first aspect, the UE 104 may drop low-priority scheduled uplink transmissions on a slot-by-slot (e.g., for each repetition) and in a given slot of multiple slots, if a low-priority scheduled uplink transmission overlaps with a high-priority scheduled uplink transmission, before and after resolving collisions between the overlapping high-priority scheduled uplink transmissions. However, if none of the high-priority scheduled uplink transmissions are PUCCH transmissions with repetition, the UE 104 may multiplex high-priority scheduled uplink transmissions. If at least one of the overlapping high-priority scheduled uplink transmissions is a PUCCH transmission with repetition, the UE 104 may drop high-priority scheduled uplink transmissions based on transmission type priority (e.g., in descending order: HARQ ACK, SR, high-priority CSI, low-priority CSI, and PUSCH).

[0079] For example, the UE 104 may identify multiple uplink transmissions that overlap in at least a first slot (e.g., slot 1) and a second slot (e.g., slot 2). As shown, a high-priority PUSCH transmission is scheduled by a first DCI in slots 0, 1, and 2 with a repetition factor of 3 (e.g., a first high-priority uplink transmission scheduled for repeated transmissions across at least the first and second slots), and a high-priority HARQ-ACK is scheduled by a second DCI in slot 1 and slot 2 (e.g., a high-priority HARQ-ACK in slot 1 comprising an additional uplink transmission in the first slot, and a high-priority HARQ-ACK in slot 2 comprising an additional uplink transmission in the second slot, e.g., a second high-priority uplink transmission). Additionally, two single-slot low-priority uplink transmissions are scheduled in slot 1 and slot 2, respectively (e.g., a low-priority uplink transmission in slot 1 comprising an additional uplink transmission in slot 1, and a low-priority uplink transmission in slot 2 comprising an additional uplink transmission in slot 2). Thus, the UE 104 may drop both low-priority scheduled uplink transmissions due to overlap with (and recurrence of) the high-priority PUSCH transmission, and drop the high-priority PUSCH transmissions in slot 1 and slot 2 due to overlap with the high-priority HARQ-ACK. For example, collision resolution in slot 1 and slot 2 is performed separately by the UE 104, such that a first collision resolution procedure is performed in the first slot and a second collision resolution procedure is performed in the second slot, where the second collision resolution procedure is independent of the first collision resolution procedure. That is, collision resolution in slot 1 does not affect collision resolution in slot 2. Even in scenarios where the first conflict resolution procedure happens to be the same as the second conflict resolution procedure, the first and second conflict resolution procedures are executed independently of each other.Each repetition of an uplink transmission (eg, HARQ-ACK or PUSCH) may be configured as a transmission scheduled by a corresponding DCI format.

[0080] Additionally or alternatively, if the UE 104 determines that at least two high priority scheduled uplink transmissions are involved in a collision and overlap in two or more slots, the UE 104 may perform a collision resolution procedure for the first slot and then for subsequent slots.

[0081] For example, in a first slot of overlapping slots between at least two high-priority scheduled uplink transmissions, the UE 104 may determine whether any of one or more low-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlaps with any of at least two high-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions in the first slot, where any of the at least two high-priority scheduled uplink transmissions are scheduled by a physical downlink control channel (PDCCH), and cancel any of the one or more low-priority scheduled uplink transmissions from the first slot based on the determination that any of the one or more low-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlaps with any of the at least two high-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions. In this example, if the at least two high-priority scheduled uplink transmissions are scheduled by the PDCCH, the UE 104 may cancel the low-priority scheduled uplink transmission as soon as DCI for one of the at least two high-priority scheduled uplink transmissions is received.

[0082] For each slot in the remaining overlapping slots in which two high priority scheduled uplink transmissions overlap, the UE 104 may first cancel the high priority scheduled uplink transmission with a lower priority type (i.e., by priority index in descending order, i.e., HARQ ACK, SR, high priority CSI, low priority CSI, and PUSCH) among the overlapping high priority scheduled uplink transmissions, and then cancel the low priority scheduled uplink transmission if it still overlaps with the remaining high priority scheduled uplink transmission.

[0083] In an example, the UE 104 may cancel only the low-priority scheduled uplink transmission in the first slot, but may not cancel the low-priority scheduled uplink transmission in the second slot based on the collision between the high-priority PUSCH transmission with repetition and the high-priority HARQ-ACK with repetition being resolved in slot 1, and the same decision should be conveyed to the remaining slots. In such an example, if the UE 104 cancels only the low-priority scheduled uplink transmission in the first slot, but not in the second slot (and any further remaining slots), the UE 104 may proceed as shown in FIG. 9, where the first and second low-priority scheduled uplink transmissions (LP PUCCH / PUSCH in slot 1 and slot 2) represent low-priority uplink transmissions scheduled for repetitive transmission across at least the first and second slots. The UE 104 may identify two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, shown in Figure 7 as a first LP PUCCH / PUSCH and an HP PUSCH that at least partially overlap in slot 1. As shown in Figure 7, the two or more scheduled uplink transmissions with different priorities that overlap in at least one slot include a first and second LP PUCCH / PUSCH and an HP PUSCH that overlaps with the first and second LP PUCCH / PUSCH in both slot 1 and slot 2. By performing one or more collision resolution procedures, as described elsewhere herein, a collision of a lower priority uplink transmission (e.g., a first LP PUCCH / PUSCH) with a higher priority uplink transmission (e.g., an HP PUSCH) is resolved by canceling the low priority uplink transmission scheduled in the first slot.However, in this example, for each slot in the remaining overlapping slots in which two high priority scheduled uplink transmissions overlap, UE 104 may resolve the collision among the high priority transmissions (e.g., according to priority index in descending order, i.e., HARQ ACK, SR, high priority CSI, low priority CSI, and PUSCH), and as described above, the HP PUSCH in slot 2 may be canceled, and UE 104 transmits the low priority transmission scheduled in the second slot because the low priority transmission now does not overlap with any transmission (e.g., any transmission among the two or more scheduled uplink transmissions with different priorities that overlap in at least one slot). In particular, if the two LP transmissions are repeated transmissions, UE 104 will proceed as shown in FIG. 9. However, if the two PUSCHs are different (i.e., non-repeated) transmissions, UE 104 will not proceed according to FIG. 9. As a result of first resolving collisions between the HP PUCCH and the HP PUSCH, there is no overlap between the LP channels and any of the HP channels.

[0084] Additionally or alternatively, the UE 104 may determine that at least one high priority scheduled uplink transmission is involved in a collision in any of the slots, and if at least one of the high priority scheduled uplink transmissions is scheduled with repetition and is scheduled by a DCI format in the PDCCH, the UE 104 may perform a collision resolution procedure for the first slot and then for subsequent slots.

[0085] For example, in a first slot (e.g., slot 0) of the plurality of slots in which one of the high priority scheduled uplink transmissions is scheduled, the UE 104 cancels any of the one or more low priority scheduled uplink transmissions and any of the at least two high priority scheduled uplink transmissions from the first slot containing the one or more high priority scheduled repeating uplink transmissions based on determining that at least one of the at least two high priority scheduled uplink transmissions is scheduled for repeating uplink transmission by DCI in the PDCCH. As shown in FIG. 7, these canceled transmissions in slot 0 are not shown for clarity. In this example, the UE 104 may recognize the high priority scheduled uplink transmission (e.g., the first of the high priority repeating uplink transmissions) in slot 0 as scheduled by the DCI format in the PDCCH.

[0086] For each slot in the remaining slots in which one of the high-priority scheduled uplink transmissions is scheduled, the UE 104 may resolve collisions among the low-priority scheduled uplink transmission, the high-priority repeat transmission, and any other high-priority scheduled uplink transmissions in that slot by configuring the high-priority uplink repeat transmission in that slot as a high-priority transmission that is not scheduled by the DCI format in the PDCCH. Thus, the UE 104 may view the high-priority scheduled uplink repeat transmissions in the remaining slots as “high-layer” configured uplink transmissions, and thus the UE 104 may not cancel a low-priority scheduled uplink transmission that overlaps with a high-priority transmission unless the UE 104 confirms that a high-priority scheduled uplink transmission is to be transmitted in this slot.

[0087] Additionally or alternatively, in the example of FIG. 7, in both slot 1 and slot 2, the UE 104 may not cancel low-priority PUSCH / PUCCH transmissions because the high-priority PUSCH transmissions in slot 1 and slot 2 are repeats of the high-priority PUSCH transmission in slot 0, and the DCI for each of these transmissions is received at least one slot earlier. In slots 1 and 2, the high-priority PUSCH is treated as an uplink transmission without a DCI format. When an overlap with other uplink transmissions occurs, the UE 104 will resolve the collision using the procedure described in FIG. 6. In particular, the UE 104 may first resolve the collision between the high-priority HARQ-ACK and the high-priority PUSCH, which results in cancellation of the high-priority PUSCH. Then, because the HARQ-ACK does not overlap with the low-priority scheduled uplink transmission, the UE 104 may not cancel the low-priority scheduled uplink transmissions in slot 1 and slot 2. Thus, the UE 104 may configure the high priority PUSCH transmissions in slot 1 and slot 2 as PUSCH transmissions without DCI format in the PDCCH.

[0088] Referring to FIG. 8, an exemplary method 800 of wireless communication may be performed by a UE 104, which may include one or more components described in FIG. 1, FIG. 3, or FIG. 11, and may transfer a data segment after performing a random access channel (RACH) procedure described above with respect to FIGS. 1-7.

[0089] At 802, the method 800 includes identifying two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, at least one of the two or more uplink transmissions being scheduled for repeated transmission across at least a first slot and a second slot. For example, in one aspect, the UE 104 may operate one or any combination of the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, or the communication component 121 to identify two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, at least one of the two or more uplink transmissions being scheduled for repeated transmission across at least a first slot and a second slot. Thus, the UE 104, antenna 1165, RF front end 1188, transceiver 1102, processor 1112, memory 1116, modem 1140, and communication component 121 may define means for identifying two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, wherein at least one of the two or more uplink transmissions is scheduled for repeated transmission across at least a first slot and a second slot.

[0090] At 804, the method 800 includes performing one or more collision resolution procedures in at least one of the first slot and the second slot for two or more scheduled uplink transmissions with different priorities that overlap in at least one slot to resolve a collision for at least one of one or more low priority scheduled uplink transmissions of the two or more scheduled uplink transmissions and one or more high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions. For example, in one aspect, the UE 104 may operate one or any combination of the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, or the communication components 121 to perform one or more collision resolution procedures in at least one of the first slot and the second slot for two or more scheduled uplink transmissions with different priorities that overlap in at least one slot to resolve a collision for at least one of one or more low priority scheduled uplink transmissions of the two or more scheduled uplink transmissions and one or more high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions. Thus, the UE 104, antenna 1165, RF front end 1188, transceiver 1102, processor 1112, memory 1116, modem 1140, and UE communication component 121 may define means for performing one or more collision resolution procedures in at least one of the first slot and the second slot for two or more scheduled uplink transmissions with different priorities that overlap in at least one slot to resolve a collision for at least one of one or more low priority scheduled uplink transmissions of the two or more scheduled uplink transmissions and one or more high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions.

[0091] In some implementations of method 800, the two or more scheduled uplink transmissions include a plurality of low priority scheduled uplink transmissions.

[0092] In some implementations of method 800, the UE communication component 121, configured to perform one or more collision resolution procedures, such as together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, further includes: determining whether any of the plurality of low priority scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH; multiplexing the plurality of low priority scheduled uplink transmissions based on a determination that none of the plurality of low priority scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH; and canceling at least one of the plurality of low priority scheduled uplink transmissions using a priority hierarchy for uplink transmissions until none of the plurality of low priority scheduled uplink transmissions overlap in any of at least one slot based on a determination that at least one of the plurality of low priority scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH.

[0093] In some implementations of method 800, the priority hierarchy indicates the priority associated with each uplink transmission type in descending priority order, including HARQ ACK, SR, high priority CSI, low priority CSI, and PUSCH.

[0094] In some implementations of method 800, the UE communication component 121, configured to perform one or more collision resolution procedures together with, for example, the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, further includes determining whether one or more low-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlap with one or more high-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions in each slot, wherein the one or more high-priority scheduled uplink transmissions are scheduled by the PDCCH, and canceling the one or more low-priority scheduled uplink transmissions based on the determination that the one or more low-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlap with one or more high-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions.

[0095] In some implementations of the method 800, the UE communication component 121, configured together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., to cancel one or more low-priority scheduled uplink transmissions, further includes canceling the one or more low-priority scheduled uplink transmissions at least one of and / or both before and after resolving a collision between multiple overlapping high-priority scheduled uplink transmissions of the two or more scheduled uplink transmissions.

[0096] In some implementations of method 800, the UE communication component 121, together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., is configured to: determine whether any of a plurality of overlapping high-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions corresponds to a repeat uplink transmission on a PUCCH; and, based on a determination that none of the plurality of overlapping high-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH, multiplex the plurality of overlapping high-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions; and canceling one or more low-priority scheduled uplink transmissions further includes canceling one or more low-priority scheduled uplink transmissions using a priority hierarchy for uplink transmissions based on a determination that any of the plurality of overlapping high-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH.

[0097] In some implementations of method 800, the UE communication component 121, configured with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., to perform one or more collision resolution procedures, includes determining whether at least two high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlap in two or more slots of the at least one slot, determining whether any of one or more low priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlaps in the first slot with at least two high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions. the method further includes determining whether any of the at least two high-priority scheduled uplink transmissions overlaps with any of the at least two high-priority scheduled uplink transmissions, wherein any of the at least two high-priority scheduled uplink transmissions is scheduled by a physical downlink control channel (PDCCH) in any of the at least one slot, and canceling any of the one or more low-priority scheduled uplink transmissions from the first slot based on the determination that any of the one or more low-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions overlaps with any of the at least two high-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions.

[0098] In some implementations of method 800, the UE communication component 121, together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., is configured to determine whether each of the at least two high-priority scheduled uplink transmissions is scheduled by the PDCCH in any of the at least one slot, and to cancel one or more low-priority scheduled uplink transmissions from the first slot, based on the determination that each of the at least two high-priority scheduled uplink transmissions is scheduled by the PDCCH in any of the at least one slot, and further includes canceling one or more low-priority scheduled uplink transmissions from the first slot upon reception of a DCI for one of the at least two high-priority scheduled uplink transmissions.

[0099] In some implementations of the method 800, the communications component 121, such as in conjunction with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, for each slot following a first slot that includes a remaining overlapping high priority scheduled uplink transmission of the at least two high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions, uses a priority hierarchy to cancel any of the at least two high priority scheduled uplink transmissions of a lower priority type, where the remaining high priority scheduled uplink transmissions of the at least two high priority scheduled uplink transmissions do not overlap; The radio frequency interference suppression unit is configured to: determine whether any of one or more low-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions overlaps with any remaining high-priority scheduled uplink transmissions, for each slot following the first slot; and cancel any of the one or more low-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions, for each slot following the first slot, based on a determination that any of the one or more low-priority scheduled uplink transmissions among the two or more scheduled uplink transmissions overlaps with any remaining high-priority scheduled uplink transmissions, for each slot following the first slot.

[0100] In some implementations of method 800, the UE communication component 121, configured to perform one or more collision resolution procedures together with, for example, the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, further includes determining whether at least two high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlap in one or more slots of the at least one slot, and determining whether at least one of the at least two high priority scheduled uplink transmissions is scheduled for repeated uplink transmission by DCI in the PDCCH based on the determination that the at least two high priority scheduled uplink transmissions of the two or more scheduled uplink transmissions overlap in one or more slots of the at least one slot.

[0101] In some implementations of method 800, the UE communication component 121, together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., is configured to cancel any of the one or more low priority scheduled uplink transmissions and any of the at least two high priority scheduled uplink transmissions from a first slot containing the repeat uplink transmission based on a determination that at least one of the at least two high priority scheduled uplink transmissions is scheduled for a repeat uplink transmission by DCI in the PDCCH.

[0102] In some implementations of method 800, the UE communication component 121, together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., is configured to: resolve, for each slot following the first slot, one or more collisions between any of the one or more low-priority scheduled uplink transmissions and any of the at least two high-priority scheduled uplink transmissions, wherein the one or more high-priority scheduled uplink transmissions in any slot following the first slot that correspond to repeated transmissions are configured as high-priority scheduled uplink transmissions that are not scheduled by DCI in the PDCCH.

[0103] In some implementations of method 800, the UE communication component 121, together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., is configured to refrain from canceling any of one or more low priority scheduled uplink transmissions that overlap with a high priority scheduled uplink transmission of the one or more high priority scheduled uplink transmissions until it confirms that the high priority scheduled uplink transmission of the one or more high priority scheduled uplink transmissions is transmitted in a slot following the first slot.

[0104] Referring to FIG. 9, an exemplary method 900 of wireless communication may be performed by a UE 104, which may include one or more components described in FIG. 1, FIG. 3, or FIG. 11, and may transfer a data segment after performing the RACH procedure described above with respect to FIGS. 1-7.

[0105] At 902, method 900 includes identifying two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, where at least one of the two or more uplink transmissions comprises a low priority uplink transmission scheduled for repeated transmission across at least a first slot and a second slot, and further comprises one or more high priority uplink transmissions scheduled in the first slot. For example, in one aspect, UE 104 may operate one or any combination of antenna 1165, RF front end 1188, transceiver 1102, processor 1112, memory 1116, modem 1140, or communications component 121 to identify two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, where at least one of the two or more uplink transmissions comprises a low priority uplink transmission scheduled for repeated transmission across at least the first slot and a second slot, and further comprises one or more high priority uplink transmissions scheduled in the first slot. Thus, the UE 104, antenna 1165, RF front end 1188, transceiver 1102, processor 1112, memory 1116, modem 1140, and communication component 121 may define means for identifying two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, wherein at least one of the two or more uplink transmissions comprises a low priority uplink transmission scheduled for repeated transmission across at least a first slot and a second slot, and further comprises one or more high priority uplink transmissions scheduled in the first slot.

[0106] At 904, the method 900 includes performing one or more collision resolution procedures in the first slot to resolve a collision of the low priority uplink transmission with one or more high priority uplink transmissions scheduled in the first slot by canceling the low priority uplink transmission scheduled in the first slot. For example, in one aspect, the UE 104 may operate one or any combination of the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, or the communications component 121 to perform one or more collision resolution procedures in the first slot to resolve a collision of the low priority uplink transmission with one or more high priority uplink transmissions scheduled in the first slot by canceling the low priority uplink transmission scheduled in the first slot. Thus, the UE 104, the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, and the communication component 121 may define means for performing one or more collision resolution procedures in the first slot to resolve a collision of a low priority uplink transmission with one or more high priority uplink transmissions scheduled in the first slot by canceling the low priority uplink transmission scheduled in the first slot.

[0107] At 906, the method 900 includes transmitting a scheduled low priority transmission in the second slot in response to the low priority uplink transmission, the low priority transmission not overlapping with any of the two or more scheduled uplink transmissions with different priorities that overlap in at least one slot. For example, in one aspect, the UE 104 may operate one or any combination of the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, or the communications component 121 to transmit a scheduled low priority transmission in the second slot in response to the low priority uplink transmission not overlapping with any of the two or more scheduled uplink transmissions with different priorities that overlap in at least one slot. Thus, the UE 104, antenna 1165, RF front end 1188, transceiver 1102, processor 1112, memory 1116, modem 1140, and communication component 121 may define means for transmitting a scheduled low priority transmission in a second slot in response to a low priority uplink transmission that does not overlap with any transmission of two or more scheduled uplink transmissions with different priorities that overlap in at least one slot.

[0108] In some implementations of the method 900, the two or more scheduled uplink transmissions include a plurality of low-priority scheduled uplink transmissions, and the UE communication component 121, configured to perform one or more collision resolution procedures, such as together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, further includes: determining whether any of the plurality of low-priority scheduled uplink transmissions corresponds to a repeat uplink transmission on a physical uplink control channel (PUCCH); multiplexing the plurality of low-priority scheduled uplink transmissions based on a determination that none of the plurality of low-priority scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH; and canceling at least one of the plurality of low-priority scheduled uplink transmissions using a priority hierarchy for uplink transmissions until none of the plurality of low-priority scheduled uplink transmissions overlap in any of at least one slot based on a determination that at least one of the plurality of low-priority scheduled uplink transmissions corresponds to a repeat uplink transmission on the PUCCH.

[0109] In some implementations of method 900, the priority hierarchy indicates the priority associated with each uplink transmission type in descending priority order, including HARQ ACK, SR, high priority CSI, low priority CSI, and PUSCH.

[0110] Referring to FIG. 10, an exemplary method 1000 of wireless communication may be performed by a UE 104, which may include one or more components described in FIG. 1, FIG. 3, or FIG. 11, and may transfer a data segment after performing the RACH procedure described above with respect to FIGS. 1-7.

[0111] At 1002, method 1000 includes identifying a plurality of scheduled uplink transmissions that overlap in at least a first slot and a second slot, the plurality of uplink transmissions comprising a first high priority uplink transmission scheduled for repeated transmission across at least the first slot and the second slot, and further comprising one or more additional uplink transmissions scheduled in the first slot and two or more additional uplink transmissions scheduled in the second slot, the two or more additional uplink transmissions scheduled in the second slot comprising at least a low priority uplink transmission and a second high priority uplink transmission. For example, in one aspect, the UE 104 may operate one or any combination of the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, or the communication component 121 to identify multiple scheduled uplink transmissions that overlap in at least a first slot and a second slot, wherein the multiple uplink transmissions comprise a first high priority uplink transmission scheduled for repeated transmission across at least the first slot and the second slot, and further comprise one or more additional uplink transmissions scheduled in the first slot and two or more additional uplink transmissions scheduled in the second slot, wherein the two or more additional uplink transmissions scheduled in the second slot comprise at least a low priority uplink transmission and a second high priority uplink transmission.Thus, the UE 104, the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, and the communication component 121 may define means for identifying multiple scheduled uplink transmissions that overlap in at least a first slot and a second slot, wherein the multiple uplink transmissions comprise a first high priority uplink transmission scheduled for repeated transmission across at least the first slot and the second slot, and further comprise one or more additional uplink transmissions scheduled in the first slot and two or more additional uplink transmissions scheduled in the second slot, wherein the two or more additional uplink transmissions scheduled in the second slot comprise at least a low priority uplink transmission and a second high priority uplink transmission.

[0112] At 1004, the method 1000 includes performing a first collision resolution procedure in a first slot and a second collision resolution procedure in a second slot, the second collision resolution procedure being unrelated to the first collision resolution procedure. For example, in one aspect, the UE 104 may operate one or any combination of the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, or the communication component 121 to perform a first collision resolution procedure in a first slot and a second collision resolution procedure in a second slot, the second collision resolution procedure being unrelated to the first collision resolution procedure. Thus, the UE 104, the antenna 1165, the RF front end 1188, the transceiver 1102, the processor 1112, the memory 1116, the modem 1140, and the communication component 121 may define means for performing a first collision resolution procedure in a first slot and a second collision resolution procedure in a second slot, wherein the second collision resolution procedure is unrelated to the first collision resolution procedure.

[0113] For example, in some implementations of method 1000, if UE 104 and / or communication component 121 cancels only a low priority scheduled uplink transmission in a first slot but not in a second slot, UE 104 and / or communication component 121 may proceed as shown in Figure 9, where the first and second low priority scheduled uplink transmissions (LP PUCCH / PUSCH in slots 1 and 2) represent low priority uplink transmissions scheduled for repeated transmission across at least the first and second slots. UE 104 and / or communication component 121 may identify two or more scheduled uplink transmissions with different priorities that overlap in at least one slot, depicted in Figure 7 as a first LP PUCCH / PUSCH and a HP PUSCH that at least partially overlap in slot 1. 7, the two or more scheduled uplink transmissions with different priorities that overlap in at least one slot include first and second LP PUCCH / PUSCHs and an HP PUSCH that overlaps with the first and second LP PUCCH / PUSCHs in both slot 1 and slot 2. By performing one or more collision resolution procedures, as described elsewhere herein, a collision of a low priority uplink transmission (e.g., the first LP PUCCH / PUSCH) with a high priority uplink transmission (e.g., the HP PUSCH) is resolved by canceling the low priority uplink transmission scheduled in the first slot. However, in this example, the low priority transmission scheduled in the second slot does not overlap with any transmission (e.g., any transmission of the two or more scheduled uplink transmissions with different priorities that overlap in at least one slot), so the UE 104 transmits the low priority transmission scheduled in the second slot.

[0114] In some implementations of method 1000, the UE communication component 121, configured together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., to perform a first collision resolution procedure in a first slot and a second collision resolution procedure in a second slot, further includes determining whether one or more low-priority scheduled uplink transmissions of the plurality of scheduled uplink transmissions overlap with one or more high-priority scheduled uplink transmissions of two or more additional scheduled uplink transmissions in each slot, wherein the one or more high-priority scheduled uplink transmissions are scheduled by a physical downlink control channel (PDCCH), and canceling the one or more low-priority scheduled uplink transmissions based on the determination that the one or more low-priority scheduled uplink transmissions of the two or more additional scheduled uplink transmissions overlap with one or more high-priority scheduled uplink transmissions of the two or more additional scheduled uplink transmissions.

[0115] In some implementations of method 1000, the UE communication component 121, configured to cancel one or more low priority uplink transmissions together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., further includes canceling the one or more low priority uplink transmissions at least one of and / or before and after resolving collisions between multiple overlapping high priority uplink transmissions among the multiple uplink transmissions.

[0116] In some implementations of the method 1000, the UE communication component 121, configured together with the transceiver 1102, the processor 1112, the memory 1116, or the modem 1140, etc., to perform a first collision resolution procedure in the first slot, further includes: determining whether at least two high-priority uplink transmissions of the plurality of uplink transmissions overlap in two or more of the first slot and the second slot; determining whether any of one or more low-priority uplink transmissions of the plurality of uplink transmissions overlaps with any of the at least two high-priority uplink transmissions of the plurality of uplink transmissions in the first slot, wherein any of the at least two high-priority uplink transmissions is scheduled by a physical downlink control channel (PDCCH); and canceling any of the one or more low-priority uplink transmissions from the first slot based on the determination that any of the one or more low-priority uplink transmissions of the plurality of uplink transmissions overlaps with any of the at least two high-priority uplink transmissions of the plurality of uplink transmissions.
