Conflict handling for parallel uplink transmissions

Cross Reference to Related Applications

The present application claims the benefit and priority of U.S. provisional application serial No. 63/138,504, entitled "COLLISION HANDLING FOR PARALLEL UPLINK TRANSMISSION (collision handling of parallel uplink transmissions)" filed on month 1, month 17 of 2021, and U.S. patent application serial No. 17/644,298, entitled "COLLISION HANDLING FOR PARALLEL UPLINK TRANSMISSION (collision handling of parallel uplink transmissions)" filed on month 12, 2021, the entire contents of which are expressly incorporated herein by reference.

Technical Field

The present disclosure relates generally to communication systems, and more particularly, to a wireless communication method including collision handling for parallel uplink transmissions.

Background

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing the available system resources. Examples of such multiple-access techniques 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.

These multiple access techniques have been employed in a variety of telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the urban, national, regional, and even global levels. One example telecommunications standard is 5G New Radio (NR). The 5G NR is part of the ongoing mobile broadband evolution promulgated by the third generation partnership project (3 GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the internet of things (IoT)) and other requirements. The 5G NR includes services associated with enhanced mobile broadband (emmbb), large-scale machine type communication (emtc), and ultra-reliable low latency communication (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There is a need for further improvements in 5G NR technology. These improvements are also applicable to other multiple access techniques and telecommunication standards employing these techniques.

Disclosure of Invention

The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

In one aspect of the disclosure, a method, computer-readable medium, and apparatus are provided. The apparatus may be a UE, and the UE may divide a plurality of channels including one or more Physical Uplink Control Channels (PUCCHs) and one or more Physical Uplink Shared Channels (PUSCHs) into two groups, the plurality of channels being scheduled for transmission on Component Carriers (CCs), the CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data; identifying a first PUSCH subset of one or more PUSCHs in a second CC set; and multiplexing a first PUCCH with a first PUSCH in a first PUSCH subset in the second CC set based on the first PUCCH of the one or more PUCCHs overlapping in time with at least a portion of the at least one PUSCH. The first PUSCH subset may be determined based on an indication received from the base station for each CC indicating whether the CC is used to communicate data or to communicate control information and data.

In some aspects, the two groups may include a first group including one or more PUCCHs and a second group including one or more PUSCHs. Dividing the plurality of channels may include: determining that the second PUCCH in the first group overlaps in time with at least a portion of the third PUCCH in the first group; and multiplexing the second PUCCH with the overlapped third PUCCH to generate the first PUCCH. The at least one PUSCH may include a first PUSCH having a first order and a second PUSCH having a second order, and the UE may further determine that the first order of the first PUSCH in the at least one PUSCH is greater than the second order of the second PUSCH in the at least one PUSCH, and determine the first PUSCH for multiplexing with the first PUCCH from the first PUSCH subset based on determining that the first order of the first PUSCH is greater.

The UE may determine the first PUSCH subset by determining a PUSCH preparation subset having the same channel priority as the first PUCCH in the at least one PUSCH, and the first PUSCH subset may be determined from the PUSCH preparation subset in the second CC set.

In some aspects, the two groups may include a first set of channels and a second set of channels, the first set of channels and the second set of channels having different channel priorities. The at least one PUSCH may include a first PUSCH having a first order and a second PUSCH having a second order, and the UE may further determine that the first order of the first PUSCH in the at least one PUSCH is greater than the second order of the second PUSCH in the at least one PUSCH, and determine the first PUSCH for multiplexing with the first PUCCH from the first PUSCH subset based on determining that the first order of the first PUSCH is greater.

The UE may resolve channel collisions between a first channel set and a second channel set having different channel priorities. In one aspect, the UE may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of a third PUSCH in the second PUSCH set, the third PUSCH and the first PUSCH multiplexed with the first PUCCH are scheduled for transmission on the same CC, and determine to discard the one of the first PUSCH or the third PUSCH multiplexed with the first PUCCH having the lower channel priority. In another aspect, the UE may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH in the second channel set, and determine to discard one of the first PUSCH multiplexed with the first PUCCH and the fourth PUCCH having a lower channel priority. In another aspect, the UE may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of a fourth PUCCH in the second channel set, and based on determining that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH, multiplex the fourth PUCCH with the first PUSCH multiplexed with the first PUCCH. In another aspect, the UE may determine a second PUSCH subset for a second set of channels in a second CC set; determining that a fifth PUCCH in the first set of channels that does not overlap any PUSCH of the first PUSCH subset overlaps in time with at least a portion of a third PUSCH in the second set of PUSCHs; and multiplexing the fifth PUCCH in the first PUSCH subset with the third PUSCH in the second PUSCH subset based on determining that the fifth PUCCH overlaps in time with at least a portion of the third PUSCH. In another aspect, the UE may determine that the fourth PUCCH in the second channel set overlaps in time with at least a portion of the fifth PUCCH in the first channel set, and multiplex the fourth PUCCH with the fifth PUCCH based on determining that the fourth PUCCH overlaps in time with at least a portion of the fifth PUCCH.

The at least one PUSCH may include a first PUSCH having a first order and a second PUSCH having a second order, and the UE may further determine that the first order of the first PUSCH in the at least one PUSCH is greater than the second order of the second PUSCH in the at least one PUSCH, and determine the first PUSCH for multiplexing with the first PUCCH from the first PUSCH subset based on determining that the first order of the first PUSCH is greater.

In one aspect, the order of PUSCH with scheduled aperiodic Channel State Information (CSI) may be determined to be greater than the order of PUSCH without scheduled aperiodic CSI. In another aspect, the order of PUSCH on the first CC may be determined to be higher than the order of PUSCH on the second CC based on the first CC index of the first CC being less than the second CC index of the second CC.

To the accomplishment of the foregoing and related ends, one or more aspects comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative features of the one or more aspects. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed and the present description is intended to include all such aspects and their equivalents.

Detailed Description

The detailed description set forth below in connection with the appended 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 various concepts. It will be apparent, however, to one 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 in order to avoid obscuring such concepts.

Several aspects of the telecommunications system will now be described with reference to various apparatus and methods. These apparatus and methods will be 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 upon the particular application and design constraints imposed on the overall system.

As an example, an element or any portion of an element or any combination of elements may be implemented as a "processing system" comprising 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, system on a chip (SoC), baseband processors, field Programmable Gate Arrays (FPGAs), programmable Logic Devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. One or more processors in the processing system may execute the software. Software should be construed broadly to mean instructions, instruction sets, code segments, program code, programs, subroutines, software components, applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referring to software, firmware, middleware, microcode, hardware description language, etc.

Thus, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, these functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer readable media includes computer storage media. A storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can 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 these 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.

While aspects and embodiments have been described in the present disclosure by way of illustration of some examples, those skilled in the art will appreciate that additional embodiments and use cases may occur in many different arrangements and scenarios. The aspects described herein may be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, embodiments and/or uses may be implemented via integrated chip implementations and other non-module component based devices (e.g., end user devices, vehicles, communication devices, computing devices, industrial equipment, retail/purchasing devices, medical devices, artificial Intelligence (AI) enabled devices, etc.). While some examples may or may not be specifically directed to use cases or applications, broad applicability of the described aspects may occur. Embodiments may range from chip-level or modular components to non-modular, non-chip-level embodiments, and further to aggregate, distributed, or Original Equipment Manufacturer (OEM) devices or systems that incorporate one or more of the described aspects. In some practical arrangements, a device incorporating the described aspects and features may also include additional components and features for practicing and practicing the claimed and described aspects. For example, the transmission and reception of wireless signals necessarily includes a plurality of components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders/summers, etc.). The aspects described herein are intended to be practiced in a variety of different size, shape, and configuration devices, chip-scale components, systems, distributed arrangements, aggregated or disassembled components, end-user devices, and the like.

Fig. 1 is a schematic diagram illustrating an example of a wireless communication system and an access network 100. A 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., a 5G core (5 GC)). Base station 102 may include a macrocell (high power cellular base station) and/or a small cell (low power cellular base station). The macrocell includes a base station. Small cells include femto cells, pico cells, and micro cells.

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 be connected with EPC 160 through a first backhaul link 132 (e.g., an S1 interface). A base station 102 configured for 5G NR, collectively referred to as a next generation RAN (NG-RAN), may be connected to a core network 190 through a second backhaul link 184. Among other functions, the base station 102 may perform one or more of the following functions: transmission 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 Services (MBMS), subscriber and device tracking, 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) through a third backhaul link 134 (e.g., an X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 may be wired or wireless.

The base station 102 may communicate wirelessly with the UE 104. Each base station 102 may provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the 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 comprising both small cells and macro cells may be referred to as a heterogeneous network. The heterogeneous network may also include a home evolved node B (eNB) (HeNB), which may provide services to a restricted group known as a Closed Subscriber Group (CSG). The communication link 120 between the base station 102 and the UE 104 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. 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 through one or more carriers. Base station 102/UE 104 may use a spectrum of up to YMHz (e.g., 5, 10, 15, 20, 100, 400MHz, etc.) bandwidth per carrier allocated in carrier aggregation for up to yxmhz (x component carriers) total transmitted in each direction. The 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., DL may be allocated more or less carriers than 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 carrier may be referred to as a secondary cell (SCell).

Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL/UL WWAN spectrum. The D2D communication link 158 may use one or more side link channels such as a physical side link broadcast channel (PSBCH), a physical side link discovery channel (PSDCH), a physical side link shared channel (PSSCH), and a physical side link control channel (PSCCH). D2D communication may be through various wireless D2D communication systems, such as WiMedia, bluetooth, zigBee, wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

The wireless communication system may also include a Wi-Fi Access Point (AP) 150 that communicates with Wi-Fi Stations (STAs) 152 via a communication link 154, for example, in a 5GHz unlicensed spectrum or the like. When communicating in the unlicensed spectrum, STA 152/AP 150 may perform Clear Channel Assessment (CCA) prior to communication to determine whether a channel is available.

The small cell 102' may operate in licensed and/or unlicensed spectrum. When operating in unlicensed spectrum, the small cell 102' may employ NR and use the same unlicensed spectrum (e.g., 5GHz, etc.) as used by the Wi-Fi AP 150. The use of small cells 102' of NR in the unlicensed spectrum may improve coverage of the access network and/or increase capacity of the access network.

The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc., based on frequency/wavelength. In 5G NR, two initial operating frequency bands have been identified as frequency range names FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6GHz, FR1 is commonly (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Similar naming problems sometimes occur for FR2, although FR2 is different from the Extremely High Frequency (EHF) band (30 GHz-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" band, FR2 is commonly (interchangeably) referred to in documents and articles as the "millimeter wave" band.

The frequency between FR1 and FR2 is commonly referred to as the intermediate frequency. Recent 5G NR studies have identified the operating band of these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). The frequency band falling into FR3 can inherit FR1 characteristics and/or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and/or FR2 to intermediate frequency. In addition, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been identified as frequency range names FR2-2 (52.6 GHz-71 GHz), FR4 (71 GHz-114.25 GHz) and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands belongs to the EHF frequency band.

In view of the above, unless specifically stated otherwise, it is to be understood that the term "sub-6 GHz" or the like (if used herein) may broadly represent frequencies that may be below 6GHz, frequencies that may be within FR1, or frequencies that may include intermediate frequency ranges. Furthermore, unless specifically stated otherwise, it is to be understood that the term "millimeter wave" or the like (if used herein) may broadly represent frequencies that may include intermediate frequency frequencies, frequencies that may be within FR2, FR4, FR2-2 and/or FR5, or frequencies that may be within the EHF band.

Base station 102, whether small cell 102' or a large cell (e.g., macro base station), may include and/or be referred to as an eNB, a gndeb (gNB), or other type of base station. Some base stations (such as the gNB 180) may operate in the traditional sub-6 GHz spectrum, millimeter wave frequencies, and/or near millimeter wave frequencies in communication with the UE 104. When the gNB 180 operates at millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. Millimeter-wave base station 180 may utilize beamforming 182 with UE 104 to compensate for path loss and short distance. The base station 180 and the UE 104 may each include multiple antennas (such as antenna elements, antenna panels, and/or antenna arrays) to facilitate beamforming.

The base station 180 may transmit the beamformed signals to the UEs 104 in one or more transmit directions 182'. The UE 104 may receive the beamformed signals from the base station 180 in one or more receive directions 182 ". The UE 104 may also transmit the beamformed signals in one or more transmit directions to the base station 180. The base station 180 may receive the beamformed signals from the UEs 104 in one or more directions. The base station 180/UE 104 may perform beam training to determine the best reception and transmission direction for each of the base station 180/UE 104. The transmission direction and the reception direction of the base station 180 may be the same or different. The transmission direction and the reception direction of the UE 104 may be the same or different.

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. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets pass through the serving gateway 166, which serving gateway 166 itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation as well as other functions. The PDN gateway 172 and BM-SC 170 are connected to an IP service 176.IP services 176 may include the internet, intranets, IP Multimedia Subsystem (IMS), 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 be used 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 broadcasting a particular service and may be responsible for session management (start/stop) and collecting charging information related to eMBMS.

The core network 190 may include access and mobility management functions (AMFs) 192, other AMFs 193, session Management Functions (SMFs) 194, and User Plane Functions (UPFs) 195. The AMF 192 may communicate 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. In general, AMF 192 provides QoS flows and session management. All user Internet Protocol (IP) packets are transmitted through UPF 195. The UPF 195 provides UE IP address assignment as well as other functions. The UPF 195 is connected to an IP service 197.IP services 197 may include internet, intranet, IP Multimedia Subsystem (IMS), packet Switched (PS) streaming (PSs) services, and/or other IP services.

A base station may include and/or be referred to as a gNB, a node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a Basic Service Set (BSS), an Extended Service Set (ESS), a Transmit Receive Point (TRP), or some other suitable terminology. The base station 102 provides an access point for the UE 104 to the EPC 160 or core network 190. Examples of UEs 104 include a cellular telephone, a smart phone, 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., MP3 player), a camera, a game console, a tablet computer, a smart device, a wearable device, a vehicle, a meter, an air pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functional device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking timers, air 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 communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, or some other suitable terminology. In some scenarios, the term UE may also apply to one or more companion devices, such as in a device constellation arrangement. One or more of these devices may access the network together and/or individually.

Referring again to fig. 1, in some aspects, the UE 104 may include a parallel uplink transmission component 198 configured to: dividing a plurality of channels including one or more PUCCHs and one or more PUSCHs into two groups, the plurality of channels being scheduled for transmission on CCs including a first set of CCs for communication data and a second set of CCs for communication control information and data; identifying a first PUSCH subset of one or more PUSCHs in a second CC set; and multiplexing a first PUCCH with a first PUSCH in a first PUSCH subset in the second CC set based on the first PUCCH of the one or more PUCCHs overlapping in time with at least a portion of the at least one PUSCH. 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.

Fig. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. Fig. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. Fig. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. Fig. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be Frequency Division Duplex (FDD) in which subframes within a subcarrier set are dedicated to DL or UL for a particular subcarrier set (carrier system bandwidth) or Time Division Duplex (TDD) in which subframes within a subcarrier set are dedicated to both DL and UL for a particular subcarrier set (carrier system bandwidth). In the example provided by fig. 2A, 2C, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (mainly DL), where D is DL, U is UL, and F is flexibility to use between DL/UL, and subframe 3 is configured with slot format 1 (all UL). Although subframes 3, 4 are shown as having slot formats 1, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. The slot formats 0, 1 are full DL, full UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE is configured with a slot format (dynamically configured by DL Control Information (DCI) or semi-statically/statically configured by Radio Resource Control (RRC) signaling) through a received Slot Format Indicator (SFI). Note that the following description also applies to the 5G NR frame structure of TDD.

Fig. 2A-2D illustrate frame structures, and aspects of the present disclosure may be applicable to other wireless communication technologies that may have different frame structures and/or different channels. One frame (10 ms) may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more slots. The subframe may also include a minislot, which may include 7, 4, or 2 symbols. Each slot may include 14 or 12 symbols depending on whether the Cyclic Prefix (CP) is normal or extended. For normal CP, each slot may include 14 symbols, and for extended CP, each slot may include 12 symbols. The symbols on DL may be CP Orthogonal Frequency Division Multiplexing (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 slots within a subframe is based on CP and parameter set (numerology). The parameter set defines the subcarrier spacing (SCS) and effectively defines the symbol length/duration, which is equal to 1/SCS.

For normal CP (14 symbols/slot), different parameter sets μ0 to 4 allow 1, 2, 4, 8 and 16 slots per subframe, respectively. For extended CP, parameter set 2 allows 4 slots per subframe. Thus, for normal CP and parameter set μ, there are 14 symbols +.Time slot sum 2 ^μ Each slot/subframe. The subcarrier spacing may be equal to 2 ^μ *15kHz, where μ is the parameter set 0 to 4. Thus, parameter set μ=0 has a subcarrier spacing of 15kHz, and parameter set μ=4 has a subcarrier spacing of 240 kHz. The symbol length/duration is inversely proportional to the subcarrier spacing. Fig. 2A to 2D provide examples of a normal CP of 14 symbols per slot and a parameter set μ=2 of 4 slots per subframe. The slot duration is 0.25ms, the subcarrier spacing is 60kHz, and the symbol duration is approximately 16.67 mus. Within a group of frames, there may be one or more frequency division multiplexed different bandwidth portions (BWP) (see fig. 2B). Each BWP may have a specific set of parameters and CPs (normal or extended).

The resource grid may be used to represent a frame structure. Each slot includes Resource Blocks (RBs) (also referred to as Physical RBs (PRBs)) that extend for 12 consecutive subcarriers. The resource grid is divided into a plurality of Resource Elements (REs). The number of bits carried by each RE depends on the modulation scheme.

As shown in fig. 2A, some REs carry a reference (pilot) signal (RS) for the UE. The RSs may include demodulation RSs (DM-RSs) (indicated as R for one particular configuration, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RSs) for channel estimation at the UE. The RSs may also include beam measurement RSs (BRSs), beam optimization RSs (BRRSs), and phase tracking RSs (PT-RSs).

Fig. 2B shows an example of various DL channels within a subframe of a frame. A Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs) (e.g., 1, 2, 4, 8, or 16 CCEs), each CCE including six RE groups (REGs), each REG including 12 consecutive REs in an OFDM symbol of an RB. The PDCCH within one BWP may be referred to as a control resource set (CORESET). The UE is configured to monitor PDCCH candidates in a PDCCH search space (e.g., common search space, UE-specific search space) during a PDCCH monitoring occasion on CORESET, wherein the PDCCH candidates have different DCI formats and different aggregation levels. Additional BWP may be located at higher and/or lower frequencies over the channel bandwidth. The Primary Synchronization Signal (PSS) may be within symbol 2 of a particular subframe of a frame. PSS is used by the UE 104 to determine subframe/symbol timing and physical layer identity. The Secondary Synchronization Signal (SSS) may be within symbol 4 of a particular subframe of a frame. SSS is used by the UE to determine the physical layer cell identification group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE may determine a Physical Cell Identifier (PCI). Based on the PCI, the UE can determine the location of the DM-RS. A Physical Broadcast Channel (PBCH) carrying a Master Information Block (MIB) may be logically grouped with PSS and SSS to form a Synchronization Signal (SS)/PBCH block (also referred to as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and a System Frame Number (SFN). The Physical Downlink Shared Channel (PDSCH) carries user data, broadcast system information, such as System Information Blocks (SIBs), not transmitted over the PBCH, and paging messages.

As shown in fig. 2C, some REs carry DM-RS for channel estimation at the base station (indicated as R for one particular configuration, but other DM-RS configurations are also possible). The UE may transmit DM-RS of a Physical Uplink Control Channel (PUCCH) and DM-RS of a Physical Uplink Shared Channel (PUSCH). PUSCH DM-RS may be transmitted in the previous or two symbols of PUSCH. The PUCCH DM-RS may be transmitted in different configurations according to whether the short PUCCH or the long PUCCH is transmitted and the specific PUCCH format used. The UE may transmit a Sounding Reference Signal (SRS). The SRS may be transmitted in the last symbol of the subframe. The SRS may have a comb structure, and the UE may transmit the SRS on one of the combs. The SRS may be used by the base station for channel quality estimation to enable frequency dependent scheduling on the UL.

Fig. 2D shows examples of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries Uplink Control Information (UCI) such as a scheduling request, a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), and hybrid automatic repeat request (HARQ) Acknowledgement (ACK) (HARQ-ACK) feedback (i.e., one or more HARQ ACK bits indicating one or more ACKs and/or Negative ACKs (NACKs)). PUSCH carries data and may additionally be used to carry Buffer Status Reports (BSR), power Headroom Reports (PHR), and/or UCI.

Fig. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In 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. Controller/processor 375 provides RRC layer functions associated with broadcast of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection setup, RRC connection modification, and RRC connection release), inter-Radio Access Technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functions associated with header compression/decompression, security (ciphering, deciphering, integrity protection, integrity verification) and handover support functions; RLC layer functions associated with transmission of upper layer Packet Data Units (PDUs), error correction by ARQ, concatenation, segmentation and reassembly of RLC Service Data Units (SDUs), re-segmentation of RLC data PDUs, and re-ordering of RLC data PDUs; and MAC layer functions associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto Transport Blocks (TBs), de-multiplexing of MAC SDUs from TBs, scheduling information reporting, error correction by HARQ, priority handling and logical channel prioritization.

The Transmit (TX) processor 316 and the Receive (RX) processor 370 implement layer 1 functions associated with various signal processing functions. Layer 1, which includes a Physical (PHY) layer, may include error detection on a transport channel, forward Error Correction (FEC) encoding/decoding of the transport channel, interleaving, rate matching, mapping to physical channels, modulation/demodulation of physical channels, and MIMO antenna processing. TX processor 316 processes 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), M-quadrature amplitude modulation (M-QAM)). The decoded 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 domain, and then combined together 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 produce a plurality of spatial streams. The channel estimates from channel estimator 374 may be used to determine coding and modulation schemes, as well as for spatial processing. The channel estimate may be derived from 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 318 TX. Each transmitter 318TX may modulate a Radio Frequency (RF) carrier with a respective spatial stream for transmission.

At the UE 350, each receiver 354RX receives a signal via its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to the Receive (RX) processor 356.TX processor 368 and RX processor 356 implement layer 1 functions associated with various signal processing functions. RX processor 356 can perform spatial processing on the information to recover any spatial streams destined for UE 350. If multiple spatial streams are destined for the UE 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 and reference signals on each subcarrier are recovered and demodulated by determining the most likely signal constellation points transmitted by base station 310. These soft decisions may be based on channel estimates computed by channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to a controller/processor 359, the controller/processor 359 implementing layer 3 and layer 2 functions.

The controller/processor 359 can be associated with a memory 360 that stores program codes and data. 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, deciphering, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller/processor 359 is also responsible for supporting error detection for HARQ operations using an ACK and/or NACK protocol.

Similar to the functionality described in connection with DL transmissions by the base station 310, the controller/processor 359 provides RRC layer functions associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functions associated with header compression/decompression and security (ciphering, deciphering, integrity protection, integrity verification); RLC layer functions associated with transmission of upper layer PDUs, error correction by ARQ, concatenation, segmentation and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and re-ordering of RLC data PDUs; and MAC layer functions 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 by HARQ, priority handling and logical channel prioritization.

Channel estimates derived by channel estimator 358 from reference signals or feedback transmitted by base station 310 may be used by TX processor 368 to select appropriate coding and modulation schemes and facilitate spatial processing. The spatial streams generated by TX processor 368 may be provided to different antenna 352 via separate transmitters 354 TX. Each transmitter 354TX may modulate an RF carrier with a respective spatial stream for transmission.

UL transmissions are processed at the base station 310 in a manner similar to that described in connection with the receiver function 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 the RX processor 370.

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

At least one of TX processor 368, RX processor 356, and controller/processor 359 may be configured to perform aspects related to 198 of fig. 1.

Fig. 4 is a diagram 400 illustrating a method of handling channel collisions for parallel uplink transmissions of wireless communications. Diagram 400 illustrates an example aspect of collision handling, where both parallel uplink transmission and first UCI multiplexing scheme may be enabled. The diagram includes a first CC 410 for control information and data transmission, a second CC 420 for data transmission and a third CC 430 for control information and data transmission, and a first PUCCH (PUCCH) on the first CC 410 ₁ ) 412, second PUCCH (PUCCH ₂ ) 414, first PUSCH (PUSCH) ₁ ) 416, a second PUSCH (PUSCH) on a second CC 420 ₂ ) 422 and a third PUSCH (PUSCH) on a third CC 430 ₃ ) 432. In some aspects, all uplink channels may have the same channel priority.

First, the UE may divide the uplink channel into two groups, including group 1 and group 2. Group 1 may include PUCCH channels, including PUCCH ₁ 412 and PUCCH ₂ 414. Group 2 may include PUSCH channels, including PUSCH ₁ 416、PUSCH ₃ 422 and PUSCH ₄ 432. The UE may first resolve the conflict within group 1. That is, the UE may first look at including PUCCH ₁ 412 and PUCCH ₂ Group 1 of 414. The UE may determine PUCCH ₁ 412 and PUCCH ₂ 414 overlap each other in time. Due to PUCCH ₁ 412 and PUCCH ₂ 414 overlap in time, so the UE may overlap the PUCCH ₁ 412 and PUCCH ₂ 414 to form a multiplexed PUCCH 419.

Next, for all PUCCHs in group 1 including multiplexed PUCCHs 419, the UE may scan all CCs and list all PUSCHs overlapping the PUCCHs in the time domain. CCs marked "data transmission" may be excluded from the list. That is, the UE may generate the PUSCH subset on the CC for control information and data transmission and data by excluding the PUSCH on the CC for data transmission. Here, due to PUSCH ₃ 422 on the second CC 420 for data transmission, so the UE may exclude PUSCH ₃ 422 and determining that the PUSCH subset may include PUSCH ₁ 416 and PUSCH ₄ 432. In addition, the UE may determine the multiplexed PUCCH 419 and PUSCH ₁ 416 and PUSCH ₄ 432 overlap. The UE may determine on which PUSCH of the PUSCH subsets the multiplexed PUCCH 419 may be piggybacked.

In this list, the UE may choose PUSCH based on some sort (or priority sort) rule. In some aspects, the ranking (ordering) may be referred to as ranking (ranking). That is, the UE may determine which one of PUSCHs overlapped with the PUCCH has the highest order, and determine to multiplex the PUCCH with the PUSCH having the highest order. In some aspects, the highest order may be referred to as the highest ranking. The PUCCH may be multiplexed with or piggybacked on the PUSCH having the highest order. That is, the UE may determine that at least one PUSCH in the PUSCH subset has a higher order than other PUSCHs, and multiplex the PUCCH to the PUSCH having the high order. In some aspects, the order of PUSCH may be preconfigured or predetermined, e.g., determined by various rules. In one aspect, PUSCH with scheduled aperiodic CSI may have a higher priority. On the other hand, PUSCH on the CC with the smallest CC index may have the highest priority.

In fig. 4, the UE may determine PUSCH ₃ 432 has the highest order, and multiplexes PUCCH 419 with PUSCH ₃ 432. Therefore, PUCCH ₁ 412 and PUCCH ₂ 414 can be combined with the PUSCH ₄ 432 multiplexing, and the UE may transmit PUSCH on the first CC ₁ 416, PUSCH transmission on the second CC ₃ 422, and transmit and PUCCH ₁ 412 and PUCCH ₂ 414 multiplexed PUSCH ₄ 432 to resolve PUCCH and PUSCH collisions in parallel uplink transmissions.

Fig. 5 is a diagram 500 illustrating a method of handling channel collisions for parallel uplink transmissions of wireless communications. Diagram 500 illustrates example aspects of collision handling with parallel uplink transmission and a second UCI multiplexing scheme enabled. The schematic diagram may include a first CC 510 for control information and data transmission, a second CC 520 for data transmission and a third CC 530 for control information and data transmission, and a third CCFirst PUCCH (PUCCH) on CC 510 ₁ ) 512, second PUCCH (PUCCH ₂ ) 514, first PUSCH (PUSCH) ₁ ) 516 and a second PUSCH (PUSCH) ₂ ) 518, third PUSCH (PUSCH) on the second CC 520 ₃ ) 522 and fourth PUSCH (PUSCH) ₄ ) 524, and a fifth PUSCH (PUSCH) on a third CC 530 ₅ ) 532. The uplink channels may have different channel priorities. That is, PUCCH ₁ 512、PUSCH ₁ 516、PUSCH ₃ 522 and PUSCH ₅ 532 may have a lower channel priority and PUCCH ₂ 514、PUSCH ₂ 518 and PUSCH ₄ 524 may have a higher channel priority.

First, the UE may divide the channel into two groups, including group 1 and group 2. Group 1 may include uplink channels with higher channel priorities and group 2 may include uplink channels with lower channel priorities. Here, group 1 may include PUCCH ₂ 514、PUSCH ₂ 518 and PUSCH ₄ 524, and group 2 may include PUCCH ₁ 512、PUSCH ₁ 516、PUSCH ₃ 522 and PUSCH ₅ 532。

Next, within each group, the UE may scan all CCs for each PUCCH, and list all PUSCHs that overlap in time with the PUCCH in the time domain. CCs marked as "data CCs" may be excluded from the list. That is, the UE may generate a preliminary subset of PUSCHs in the group and generate a subset of PUSCH candidates with which each PUCCH may be multiplexed.

Here, in group 1, since PUSCH ₄ 524 on the second CC 520 for data transmission, so the UE may exclude PUSCH ₄ 524 and determines PUCCH ₂ The PUSCH subset of 514 may include PUSCH ₂ 518. In group 2, due to PUSCH ₃ 522 on the second CC 520 for data transmission, so the UE may exclude PUSCH ₃ 522 and determining PUCCH ₁ The PUSCH subset of 512 may include PUSCH ₁ 516 and PUSCH ₅ 532。

In this list, the UE may select PUSCH based on a certain order (or prioritization). That is, the UE may determine which one of PUSCHs overlapped with the PUCCH has the highest order, and determine to multiplex the PUCCH with the PUSCH having the highest order. The PUCCH may be multiplexed with or piggybacked on the PUSCH having the highest order. That is, the UE may determine that at least one PUSCH in the PUSCH subset has a higher order than other PUSCHs, and multiplex the PUCCH to the PUSCH having the higher order. In some aspects, the order of PUSCH may be determined by various rules. In one aspect, PUSCH with scheduled aperiodic CSI may have a higher priority. On the other hand, PUSCH on the CC with the smallest CC index may have the highest priority.

Here, for group 1, the ue may determine PUCCH ₂ 514 and PUSCH ₂ 518 overlap in time and PUCCH is taken up ₂ 514 and PUSCH ₂ 518, multiplexing. For group 2, the ue may determine PUCCH ₁ 512 and PUSCH ₁ 516 and PUSCH ₅ 532 overlap in time and determine PUSCH ₅ 532 has a specific PUSCH ₁ 516 higher order. The UE may use PUCCH ₁ 512 and PUSCH ₅ 532.

Finally, the UE may resolve collisions within each CC and between different CCs. After resolving the conflict within each group, the UE may check across the two groups. For collisions of channels with different channel priorities, the UE may send channels with higher channel priorities and discard transmissions of channels with lower channel priorities unless both channels are PUSCH and they are on different CCs. Two PUSCHs on different CCs may be transmitted simultaneously.

Here, PUCCH by collision resolution within group 1 and group 2 ₁ 512 and PUSCH ₅ 532 is multiplexed, and PUCCH ₂ 514 and PUSCH ₂ 518 multiplexing. Thus, the UE may now have a Physical Uplink Control Channel (PUCCH) ₂ 514 multiplexed PUSCH ₁ 516、PUSCH ₂ 518 with PUCCH ₁ 512 multiplexed PUSCH ₃ 522、PUSCH ₄ 524 and PUSCH ₅ 532. In the first CC 510, PUSCH ₁ 516 has a lower channel priority and is with PUCCH ₂ 514 multiplexed PUSCH ₂ 518 has a higher channel priority, and the UE may discard PUSCH ₁ 516. In the second CC 520, PUSCH ₃ 522 have lower channel priority, PUSCH ₄ 524 has a higher channel priority and the UE may discard PUSCH ₄ 524. Thus, the UE may transmit with the PUCCH on the first CC 510 ₂ 514 multiplexed PUSCH ₂ 518, PUSCH transmission on the second CC 520 ₄ 524, and transmit with PUCCH on third CC 530 ₁ 512 multiplexed PUSCH ₅ 532, and resolves PUCCH and PUSCH collisions in parallel uplink transmissions.

Fig. 6 is a diagram 600 illustrating a method of handling channel collisions for parallel uplink transmissions of wireless communications. Diagram 600 may illustrate collision handling, including parallel uplink transmission and a third UCI multiplexing scheme enabled on top of the first UCI multiplexing scheme. The diagram may include a first CC 610 for control information and data transmission, a second CC 620 for data transmission and a third CC 630 for control information and data transmission, and a first PUCCH (PUCCH) on the first CC 610 ₁ ) 612, second PUCCH (PUCCH ₂ ) 614, first PUSCH (PUSCH) ₁ ) 616 and a second PUSCH (PUSCH) ₂ ) 618, a third PUSCH (PUSCH) on a second CC 620 ₃ ) 622 and a fourth PUSCH (PUSCH) ₄ ) 624, fifth PUSCH (PUSCH) on the third CC 630 ₅ ) 632 and sixth PUSCH (PUSCH) ₆ ) 634. The uplink channels may have different channel priorities. That is, PUCCH ₁ 612、PUSCH ₁ 616、PUSCH ₃ 622 and PUSCH ₅ 632 may have a lower channel priority and PUCCH ₂ 614、PUSCH ₂ 618、PUSCH ₄ 624 and PUSCH ₆ 634 may have a higher channel priority.

First, the UE may divide the uplink channel into two groups, including group 1 and group 2. Group 1 may include PUCCH channels, including PUCCH ₁ 612 and PUCCH ₂ 614. Group 2 may include PUSCH channels, including PUSCH ₁ 616、PUSCH ₂ 618、PUSCH ₂ 622、PUSCH ₄ 624、PUSCH ₅ 632 and PUSCH ₆ 634. The UE may first resolve the conflict within group 1. That is, the UE may first look at including PUCCH ₁ 612 and PUCCH ₂ Set 1 of 614. The UE may determine PUCCH ₁ 612 and PUCCH ₂ 614 overlap each other in time. Due to PUCCH ₁ 612 and PUCCH ₂ 614 overlap in time, so the UE may overlap the PUCCH ₁ 612 and PUCCH ₂ 614 are multiplexed into a multiplexed PUCCH 619.

Next, for all PUCCHs of group 1 including the multiplexed PUCCH 419, the UE may scan all CCs and list all PUSCHs having the same priority overlapping the PUCCHs in the time domain based on priority levels (high or low) of the PUCCHs. CCs marked "data transmission" may be excluded from the list. That is, for each PUCCH, the UE may generate a PUSCH preparation subset having the same channel priority as the corresponding PUCCH. According to the PUSCH preparation subset, the UE may generate a PUSCH subset on the CCs for control information and data transmission and data by excluding the PUSCH on the CCs for data transmission.

Here, the multiplexed PUCCH 619 has a higher channel priority, so the PUSCH preparation subset may include PUSCHs with higher priority, including PUSCH ₂ 618、PUSCH ₄ 624 and PUSCH ₆ 634. According to the PUSCH preparation subset, due to PUSCH ₄ 624 on the second CC 620 for data transmission, so the UE may exclude PUSCH ₄ 624 and determining that the PUSCH subset may include PUSCH ₂ 618 and PUSCH ₆ 634. The UE may determine the multiplexed PUCCH 619 and PUSCH ₂ 618 and PUSCH ₆ 634 overlap. The UE may determine on which PUSCH of the PUSCH subsets the multiplexed PUCCH 619 may be piggybacked.

The UE may select PUSCH based on a certain order (or prioritization). That is, the UE may determine which one of PUSCHs overlapped with the PUCCH has the highest order, and determine to multiplex the PUCCH with the PUSCH having the highest order. The PUCCH may be multiplexed with or piggybacked on the PUSCH having the highest order. That is, the UE may determine that at least one PUSCH in the PUSCH subset has a higher order than other PUSCHs, and multiplex the PUCCH to the PUSCH having the higher order. In some aspects, the order of PUSCH may be determined by various rules. In one aspect, PUSCH with scheduled aperiodic CSI may have a higher priority. On the other hand, PUSCH on the CC with the smallest CC index may have the highest priority.

Here, the UE may determine PUSCH ₂ 618 has a specific PUSCH ₆ 634 higher order, and to multiplex PUCCH 619 with PUSCH ₂ 618, multiplexing. Therefore, PUCCH ₁ 612 and PUCCH ₂ 614 can be combined with PUSCH ₂ 618 multiplexing. Thus, the UE may now have a Physical Uplink Control Channel (PUCCH) on the first CC 610 ₁ 612 and PUCCH ₂ 614 multiplexed PUSCH ₁ 616、PUSCH ₂ 618 have PUSCH on the second CC 620 ₃ 622 and PUSCH ₄ 624, and on the third CC 630 PUSCH ₅ 632 and PUSCH ₆ 634. In the first CC 610, PUSCH ₁ 616 has a lower channel priority, so the UE can discard PUSCH ₁ 616 and transmit and PUCCH ₁ 612 and PUCCH ₂ 614 multiplexed PUSCH ₂ 618. In the second CC 620, PUSCH ₃ 622 has a lower channel priority, so the UE can discard PUSCH ₃ 622 and PUSCH4 624. In the third CC 630, PUSCH ₅ 632 has a lower channel priority, so the UE can discard PUSCH ₅ 632 and transmitting PUSCH ₆ 634. Thus, the UE may resolve PUCCH and PUSCH collisions in parallel uplink transmissions.

Fig. 7 is a diagram 700 illustrating a method of handling channel collisions for parallel uplink transmissions of wireless communications. Diagram 700 may illustrate collision handling, including both parallel uplink transmission and a third UCI multiplexing scheme enabled on top of the second UCI multiplexing scheme. The diagram may include a first CC 710 for control information and data transmission, a second CC 720 for data transmission and a third CC 730 for control information and data transmission, and a first PUCCH (PUCCH) on the first CC 710 ₁ ) 712, second PUCCH (PUCCH) ₂ ) 714 and a second PUSCH (PUSCH) ₂ )718, a third PUSCH (PUSCH) on the second CC 720 ₃ ) 722 and fourth PUSCH (PUSCH ₄ ) 724, and a sixth PUSCH (PUSCH) on a third CC 730 ₆ ) 734. The uplink channels may have different channel priorities. That is, PUCCH ₁ 712 and PUSCH ₃ 722 may have a lower channel priority and PUCCH ₂ 714、PUSCH ₂ 718、PUSCH ₄ 724 and PUSCH ₆ 734 may have a higher channel priority.

First, the UE may divide the channel into two groups, including group 1 and group 2. Group 1 may include uplink channels with higher channel priorities and group 2 may include uplink channels with lower channel priorities. Here, group 1 may include PUCCH ₂ 714、PUSCH ₂ 718、PUSCH ₄ 724 and PUSCH ₆ 734, and group 2 may include PUCCH ₁ 712 and PUSCH ₃ 722。

Here, in group 1, since PUSCH ₄ 724 on the second CC 720 for data transmission, so UE may exclude PUSCH ₄ 724 and determining PUCCH ₂ The PUSCH subset of 714 may include PUSCH ₂ 718 and PUSCH ₆ 734. In group 2, due to PUSCH ₃ 722 is on the second CC 720 for data transmission, so the UE may exclude PUSCH ₃ 722 and determining PUCCH ₁ The PUSCH subset of 712 does not include candidates.

In this list, the UE may select PUSCH based on a certain order (or prioritization). That is, the UE may determine which one of PUSCHs overlapped with the PUCCH has the highest order, and determine to multiplex the PUCCH with the PUSCH having the highest order. The PUCCH may be multiplexed with or piggybacked on the PUSCH having the highest order. That is, the UE may determine that at least one PUSCH in the PUSCH subset has a higher order than other PUSCHs, and multiplex the PUCCH to the PUSCH having the higher order. In some aspects, the order of PUSCH may be preconfigured or predetermined, e.g., determined by various rules. In one aspect, PUSCH with scheduled aperiodic CSI may have a higher priority. On the other hand, PUSCH on the CC with the smallest CC index may have the highest priority.

Here, for group 1, the ue may determine PUCCH ₂ 714 and PUSCH ₂ 718 and PUSCH ₆ 734 overlap in time and determine PUSCH ₂ 718 has a specific PUSCH ₆ 734 higher order. The UE may use PUCCH ₂ 714 and PUSCH ₂ 718, multiplexing. For group 2, the ue may determine PUCCH ₁ 712 there are no PUSCH candidates within group 2.

Finally, the UE may resolve collisions within each CC and between different CCs. After resolving the collision within each group, the UE may check for overlap of channels with different priorities across the two groups. If the PUCCHs overlap PUCCHs having different priorities, the UE may multiplex the overlapped PUCCHs. If the PUSCH overlaps PUSCH with a different channel priority on the same CC, the UE may discard transmissions of lower priority PUSCHs. If the overlapped PUSCHs are on different CCs, the UE may simultaneously transmit the overlapped PUSCHs. If the PUCCH overlaps PUSCH with a different channel priority, the UE may multiplex the PUCCH with PUSCH with a different channel priority after excluding CCs marked "data transmission". The UE may follow the same procedure of generating the PUSCH subsets and selecting one PUSCH from the PUSCH subsets based on the order of the PUSCHs.

Here, the UE may transmit PUCCH ₁ 712 and PUSCH ₂ 718 and PUCCH on first CC 710 ₂ 714. PUSCH on second CC 720 ₃ 722 and PUSCH ₄ 724 and PUSCH on a third CC 730 ₆ 734, multiplexed. For PUCCH ₁ 712, the ue may determine PUSCH ₃ 722 and PUSCH ₄ 724 on a second CC 720 for data transmission, and PUCCH ₁ The PUSCH subset of 712 may be packagedDrawn and matched PUCCH ₂ 714 and PUSCH ₆ 734 multiplexed PUSCH ₂ 718. The UE may determine PUCCH ₁ 712 sum PUCCH ₂ 714 and PUSCH ₆ 734 multiplexed PUSCH ₂ 718 overlap. The UE may determine to be with PUCCH ₂ 714 multiplexed PUSCH ₂ 718 has a specific PUSCH ₆ 734 higher order, and the UE may put PUCCH ₁ 712 AND PUSCH ₂ 714 multiplexed PUSCH ₂ 718, multiplexing.

Thus, the UE can now use PUSCH ₂ 718 and PUCCH on first CC 710 ₁ 712 and PUCCH ₂ 714. PUSCH on second CC 720 ₃ 722 and PUSCH ₄ 724 and PUSCH on a third CC 730 ₆ 734, multiplexed. For the second CC 720, pusch ₃ 722 has a lower channel priority, so the UE can discard PUSCH ₃ 722 and PUSCH4 724. Thus, the UE may transmit with the PUCCH on the first CC 710 ₁ 712 and PUCCH ₂ 714 multiplexed PUSCH ₂ 718, PUSCH transmission on a second CC 720 ₄ 724, and transmitting PUSCH on the third CC 730 ₆ 734. Thus, the UE may resolve PUCCH and PUSCH collisions in parallel uplink transmissions.

Fig. 8 is a communication diagram 800 of a wireless communication method. The communication diagram 800 may include a UE 802 and a base station 804. The UE 802 may divide a plurality of channels including PUCCH and PUSCH into two groups, the plurality of channels scheduled for transmission on a first CC set for communicating data and a second CC set for communicating control information and data; determining a first PUSCH subset of one or more PUSCHs in the second CC set; determining that a first PUCCH of the one or more PUCCHs overlaps in time with at least a portion of at least one PUSCH of the first PUSCH subset; and multiplexing the first PUCCH with the first PUSCH in the first PUSCH subset based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH.

At 806, the base station 804 may send an indication of CCs to the UE 802, the CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. The UE 802 may receive an indication of CCs from the base station 804, the CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Here, the signal indicating the CC may indicate which CC supports parallel uplink transmission. That is, the signal may indicate a first CC set for transferring data and a second CC set for transferring control information and data.

At 807, the base station 804 may send instructions to the UE 802 to schedule multiple channels for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. The UE 802 may receive instructions from a base station 804 to schedule a plurality of channels for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. That is, the plurality of channels may include one or more PUCCHs and one or more PUSCHs. In an aspect, one or more PUCCHs may be scheduled to be transmitted on the first CC set or the second CC set, and one or more PUSCHs may be scheduled to be transmitted on the second CC set.

At 808, the UE 802 may divide a plurality of channels including one or more PUCCHs and one or more PUSCHs into two groups, the plurality of channels scheduled for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. In one aspect, the two groups may include a first group including one or more PUCCHs and a second group including one or more PUSCHs. In another aspect, the two groups may include a first channel set and a second channel set having different channel priorities.

At 810, based on dividing the plurality of channels into two groups including a first group (including one or more PUCCHs) and a second group (including one or more PUSCHs) at 808, the UE 802 may determine that the second PUCCH in the first group overlaps in time with at least a portion of the third PUCCH in the first group.

At 812, based on determining at 810 that the second PUCCH in the first group overlaps in time with at least a portion of the third PUCCH in the first group, UE 802 may multiplex the second PUCCH with the overlapping third PUCCH to generate the first PUCCH.

At 814, the UE 802 may determine a PUSCH preparation subset for at least one PUSCH having the same channel priority as the first PUCCH. That is, for each PUCCH, the UE 802 may generate a PUSCH preparation subset with the same channel priority as the corresponding PUCCH. From the PUSCH preparation subset, the UE 802 may generate a PUSCH subset on the CCs for control information and data transmission and data by excluding the PUSCH on the CCs for data transmission.

At 816, the UE 802 may determine a first PUSCH subset of one or more PUSCHs in the second CC set. The first PUSCH subset may be determined based on an indication for each CC received from the base station 804 at 806, the indication indicating whether the CC is used to communicate data or to communicate control information and data. In an aspect, the first PUSCH subset may be determined from the preliminary PUSCH subset in the second CC set, as determined at 814.

At 820, a first PUCCH of the one or more PUCCHs may overlap in time with at least a portion of at least one PUSCH of the first PUSCH subset, and the at least one PUSCH may include a first PUSCH having a first order and a second PUSCH having a second order, and the UE 802 may determine that the first order of the first PUSCH of the at least one PUSCH is greater than the second order of the second PUSCH of the at least one PUSCH. Based on determining that the first order of the first PUSCH is greater, the first PUSCH for multiplexing with the first PUCCH is determined from the first PUSCH subset.

In one aspect, a first order of a first PUSCH with scheduled aperiodic CSI may be determined to be greater than a second order of a second PUSCH without scheduled aperiodic CSI. In another aspect, the first order of the first PUSCH on the first CC may be higher than the second order of the second PUSCH on the second CC based on the first CC index of the first CC being less than the second CC index of the second CC.

At 822, based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH, the UE 802 may multiplex the first PUCCH with the first PUSCH in the first PUSCH subset.

At 824, the UE 802 may resolve channel collisions between the first and second channel sets having different channel priorities. In an aspect, if channels with different priorities collide, the UE 802 may transmit the channel with the higher channel priority and discard the channel with the lower channel priority unless both the high priority channel and the low priority channel are PUSCHs on different CCs, where the UE 802 may transmit them simultaneously. That is, the UE may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of a third PUSCH in the second PUSCH set, the third PUSCH and the first PUSCH multiplexed with the first PUCCH are scheduled for transmission on the same CC, and determine to discard one of the first PUSCH or the third PUSCH multiplexed with the first PUCCH having a lower channel priority. In another aspect, the UE 802 may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH in the second channel set, and determine to discard the one of the first PUSCH multiplexed with the first PUCCH and the fourth PUCCH having the lower channel priority.

On the other hand, if the PUCCH overlaps with PUSCH having a priority different from the PUCCH, the UE 802 may follow the procedure at 820 and/or 822. That is, the UE 802 may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH in the second channel set, and multiplex the fourth PUCCH with the first PUSCH multiplexed with the first PUCCH based on determining that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH. In another aspect, the UE 802 may determine a second PUSCH subset of the second set of channels in the second CC set, determine that a fifth PUCCH of the first set of channels that does not overlap any PUSCH of the first PUSCH subset overlaps in time with at least a portion of a third PUSCH of the second PUSCH set, and multiplex the fifth PUCCH of the first PUSCH subset with the third PUSCH of the second PUSCH set based on determining that the fifth PUCCH overlaps in time with at least a portion of the third PUSCH.

On the other hand, when PUCCHs overlap PUCCHs having priorities different from PUCCHs, the UE 802 may multiplex the PUCCHs. That is, the UE 802 may determine that the fourth PUCCH in the second channel set overlaps in time with at least a portion of the fifth PUCCH in the first channel set, and multiplex the fourth PUCCH with the fifth PUCCH based on determining that the fourth PUCCH overlaps in time with at least a portion of the fifth PUCCH.

At 826, the UE 802 may transmit at least one channel of a plurality of channels including one or more PUCCHs and one or more PUSCHs to the base station 804. The base station 804 may receive at least one channel of a plurality of channels including one or more PUCCHs and one or more PUSCHs from the UE 802. Here, at least one channel of the plurality of channels may be determined by resolving channel collisions between a first channel set and a second channel set having different channel priorities.

Fig. 9 is a flow chart 900 of a method of wireless communication. The method may be performed by a UE (e.g., UE 104; apparatus 1202). The UE may divide a plurality of channels including PUCCHs and PUSCHs into two groups, the plurality of channels scheduled for transmission on a first CC set for communicating data and a second CC set for communicating control information and data, determine a first PUSCH subset of one or more PUSCHs in the second CC set, determine that a first PUCCH of the one or more PUCCHs overlaps in time with at least a portion of at least one PUSCH of the first PUSCH subset, and multiplex the first PUCCH with the first PUSCH of the first PUSCH subset based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH.

At 902, the UE may receive an indication of a CC from a base station 804, the CC comprising a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Here, the signal indicating the CC may indicate which CC supports parallel uplink transmission. That is, the signal may indicate a first CC set for transferring data and a second CC set for transferring control information and data. For example, at 806, the UE 802 may receive an indication of CCs from the base station 804, the indication including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Further, 902 can be performed by a parallel uplink transmission component 1240.

At 903, the UE may receive an instruction from the base station to schedule multiple channels for transmission on a CC that includes a first set of CCs for communicating data and a second set of CCs for communicating control information and data. That is, the plurality of channels may include one or more PUCCHs and one or more PUSCHs. In an aspect, one or more PUCCHs may be scheduled to be transmitted on the first CC set or the second CC set, and one or more PUSCHs may be scheduled to be transmitted on the second CC set. For example, at 807, the UE 802 may receive instructions from the base station 804 to schedule a plurality of channels for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Further 903 may be performed by a parallel uplink transmit component 1240.

At 904, the UE may divide a plurality of channels including one or more PUCCHs and one or more PUSCHs into two groups, the plurality of channels scheduled for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. In one aspect, the two groups may include a first group including one or more PUCCHs and a second group including one or more PUSCHs. In another aspect, the two groups may include a first set of channels and a second set of channels, the first set of channels and the second set of channels having different channel priorities. For example, at 808, the UE 802 may divide a plurality of channels including one or more PUCCHs and one or more PUSCHs into two groups, the plurality of channels being scheduled for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Further, 904 can be performed by a parallel uplink transmission component 1240.

At 906, based on dividing the plurality of channels into two groups including a first group (including one or more PUCCHs) and a second group (including one or more PUSCHs) at 904, the UE may determine that the second PUCCH in the first group overlaps in time with at least a portion of the third PUCCH in the first group. For example, at 810, the UE 802 may determine that the second PUCCH in the first group overlaps in time with at least a portion of the third PUCCH in the first group. Further, 906 can be performed by a parallel uplink transmission component 1240.

At 908, the UE may multiplex the second PUCCH with the overlapping third PUCCH to generate the first PUCCH. Here, based on determining that the second PUCCH in the first group overlaps in time with at least a portion of the third PUCCH in the first group at 906, the UE may multiplex the second PUCCH with the overlapping third PUCCH to generate the first PUCCH, e.g., at 812, the UE 802 may multiplex the second PUCCH with the overlapping third PUCCH to generate the first PUCCH. Further, 908 may be performed by a parallel uplink transmission component 1240.

At 910, the UE may determine a PUSCH preparation subset of at least one PUSCH having the same channel priority as the first PUCCH. That is, for each PUCCH, the UE may generate a PUSCH preparation subset having the same channel priority as the corresponding PUCCH. According to the PUSCH preparation subset, the UE may generate a PUSCH subset on the CCs for control information and data transmission and data by excluding the PUSCH on the CCs for data transmission. For example, at 814, UE 802 may determine a PUSCH preparation subset for at least one PUSCH having the same channel priority as the first PUCCH. Further, 910 may be performed by a parallel uplink transmission component 1240.

At 912, the UE may determine a first PUSCH subset of one or more PUSCHs in the second CC set. Wherein the first PUSCH subset may be identified based on an indication for each CC received from the base station at 806, the indication indicating whether the CC is used to communicate data or to communicate control information and data. In an aspect, the first PUSCH subset may be determined from the preliminary PUSCH subset in the second CC set, as determined at 910. For example, at 816, the UE 802 may determine a first PUSCH subset of one or more PUSCHs in the second CC set. Further, 912 can be performed by parallel uplink transmission component 1240.

At 916, a first PUCCH of the one or more PUCCHs may overlap in time with at least a portion of at least one PUSCH of the first PUSCH subset, and the at least one PUSCH includes a first PUSCH having a first order and a second PUSCH having a second order, and the UE may determine that the first order of the first PUSCHs of the at least one PUSCH is greater than the second order of the second PUSCHs of the at least one PUSCH, determine the first PUSCH for multiplexing with the first PUCCH from the first PUSCH subset based on determining that the first order of the first PUSCHs is greater. In one aspect, a first order of a first PUSCH with scheduled aperiodic CSI may be determined to be greater than a second order of a second PUSCH without scheduled aperiodic CSI. In another aspect, the first order of the first PUSCH on the first CC may be higher than the second order of the second PUSCH on the second CC based on the first CC index of the first CC being less than the second CC index of the second CC. For example, at 820, the ue 802 may determine that a first order of a first PUSCH of the at least one PUSCH is greater than a second order of a second PUSCH of the at least one PUSCH; and determining a first PUSCH for multiplexing with the first PUCCH from the first PUSCH subset based on determining that the first order of the first PUSCH is greater. Further, 916 may be performed by parallel uplink transmission component 1240.

At 918, based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH, the UE may multiplex the first PUCCH with the first PUSCH in the first PUSCH subset. For example, at 822, based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH, UE 802 may multiplex the first PUCCH with the first PUSCH in the first PUSCH subset. Furthermore, 918 can be performed by a parallel uplink transmission component 1240.

At 920, the UE may resolve channel collisions between a first channel set and a second channel set having different channel priorities. In one aspect, when channels with different priorities collide, the UE may transmit channels with higher channel priorities and discard channels with lower channel priorities unless both the high priority channel and the low priority channel are PUSCHs on different CCs, where the UE may transmit them simultaneously. In another aspect, when the PUCCH overlaps with PUSCH having a priority different from the PUCCH, the UE may follow the procedure at 916 and/or 918. On the other hand, when PUCCHs overlap PUCCHs having priorities different from the PUCCHs, the UE may multiplex the PUCCHs. On the other hand, if the PUCCH overlaps with PUSCH having a priority different from the PUCCH, the UE may follow the procedure at 820 and/or 822. That is, the UE may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH in the second channel set, and multiplex the fourth PUCCH with the first PUSCH multiplexed with the first PUCCH based on determining that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH. In another aspect, the UE may determine a second PUSCH subset of the second set of channels in the second CC set, determine that a fifth PUCCH of the first set of channels that does not overlap any PUSCH of the first PUSCH subset overlaps in time with at least a portion of a third PUSCH of the second PUSCH set, and multiplex the fifth PUCCH of the first PUSCH subset with the third PUSCH of the second PUSCH set based on determining that the fifth PUCCH overlaps in time with at least a portion of the third PUSCH. On the other hand, when PUCCHs overlap PUCCHs having priorities different from those PUCCHs, the UE may multiplex the PUCCHs. That is, the UE may determine that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH in the second channel set, and multiplex the fourth PUCCH with the first PUSCH multiplexed with the first PUCCH based on determining that the first PUSCH multiplexed with the first PUCCH overlaps in time with at least a portion of the fourth PUCCH. For example, at 824, the UE 802 may resolve channel collisions between a first set of channels and a second set of channels having different channel priorities. Further, 920 may be performed by a parallel uplink transmission component 1240.

At 922, the UE may transmit at least one channel of a plurality of channels including one or more PUCCHs and one or more PUSCHs to the base station. Here, at least one channel of the plurality of channels may be determined by resolving channel collisions between a first channel set and a second channel set having different channel priorities. For example, at 826, the UE 802 may transmit at least one of a plurality of channels including one or more PUCCHs and one or more PUSCHs to the base station 804. Further 922 may be performed by a parallel uplink transmission component 1240.

At 1004, the UE may divide a plurality of channels including one or more PUCCHs and one or more PUSCHs into two groups, the plurality of channels being scheduled for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. In one aspect, the two groups may include a first group including one or more PUCCHs and a second group including one or more PUSCHs. In another aspect, the two groups may include a first set of channels and a second set of channels, the first set of channels and the second set of channels having different channel priorities. For example, at 808, the UE 802 may divide a plurality of channels including one or more PUCCHs and one or more PUSCHs into two groups, the plurality of channels being scheduled for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Further, 1004 can be performed by a parallel uplink transmission component 1240.

At 1012, the UE may determine a first PUSCH subset of one or more PUSCHs in the second CC set. Wherein the first PUSCH subset may be identified based on an indication for each CC received from the base station at 806, the indication indicating whether the CC is used to communicate data or to communicate control information and data. In an aspect, the first PUSCH subset may be determined from the preliminary PUSCH subset in the second CC set, as determined at 1010. For example, at 816, the UE 802 may determine a first PUSCH subset of one or more PUSCHs in the second CC set. Further, 1012 may be performed by parallel uplink transmission component 1240.

At 1018, based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH, the UE may multiplex the first PUCCH with the first PUSCH in the first PUSCH subset. For example, at 822, based on determining that the first PUCCH overlaps in time with at least a portion of the at least one PUSCH, UE 802 may multiplex the first PUCCH with the first PUSCH in the first PUSCH subset. Further, 1018 may be performed by parallel uplink transmit component 1240.

Fig. 11 is a flow chart 1100 of a method of wireless communication. The method may be performed by a base station (e.g., base station 102/180; apparatus 1302). The base station may transmit an indication of a first Component Carrier (CC) set including a first CC set for communicating data and a second CC set for communicating control information and data to the UE, and an instruction to schedule a plurality of channels on CCs including the first CC set for communicating data and the second CC set for communicating control information and data, and receive at least one of the plurality of channels from the UE.

At 1102, a base station may send an indication of CCs to a UE, the indication including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Here, the signal indicating the CC may indicate which CC supports parallel uplink transmission. That is, the signal may indicate a first CC set for transferring data and a second CC set for transferring control information and data. For example, at 806, the base station 804 may send an indication of CCs to the UE 802, the indication including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Further, 1106 can be performed by a parallel uplink receive component 1340.

At 1103, the base station may send instructions to the UE to schedule a plurality of channels for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. That is, the plurality of channels may include one or more PUCCHs and one or more PUSCHs. In an aspect, one or more PUCCHs may be scheduled to be transmitted on the first CC set or the second CC set, and one or more PUSCHs may be scheduled to be transmitted on the second CC set. For example, at 807, base station 804 may send instructions to UE 802 to schedule multiple channels for transmission on CCs including a first set of CCs for communicating data and a second set of CCs for communicating control information and data. Further, 1108 can be performed by a parallel uplink receive component 1340.

At 1122, the base station may receive at least one channel of a plurality of channels including one or more PUCCHs and one or more PUSCHs from the UE. Here, at least one channel of the plurality of channels may be determined by resolving channel collisions between a first channel set and a second channel set having different channel priorities. For example, at 826, the base station 804 may receive at least one channel of a plurality of channels including one or more PUCCHs and one or more PUSCHs from the UE 802. Further, 1110 may be performed by parallel uplink receive component 1340.

Fig. 12 is a schematic diagram 1200 illustrating an example of a hardware implementation of an apparatus 1202. The apparatus 1202 may be a UE, a component of a UE, or may implement UE functionality. In some aspects, the apparatus 1202 may include a cellular baseband processor 1204 (also referred to as a modem) coupled to a cellular RF transceiver 1222. In some aspects, the apparatus 1202 may also include one or more Subscriber Identity Module (SIM) cards 1220, an application processor 1206 coupled to a Secure Digital (SD) card 1208 and a screen 1210, a bluetooth module 1212, a Wireless Local Area Network (WLAN) module 1214, a Global Positioning System (GPS) module 1216, and a power supply 1218. The cellular baseband processor 1204 communicates with the UE 104 and/or BS 102/180 via a cellular RF transceiver 1222. The cellular baseband processor 1204 may include a computer readable medium/memory. The computer readable medium/memory may be non-transitory. The cellular baseband processor 1204 is responsible for general processing, including the execution of software stored in the computer-readable medium/memory. The software, when executed by the cellular baseband processor 1204, causes the cellular baseband processor 1204 to perform the various functions described supra. The computer readable medium/memory can also be used for storing data that is manipulated by the cellular baseband processor 1204 when executing software. The cellular baseband processor 1204 also includes a receive component 1230, a communication manager 1232, and a transmit component 1234. The communications manager 1232 includes one or more of the illustrated components. Components within the communications manager 1232 may be stored in a computer readable medium/memory and/or configured as hardware within the cellular baseband processor 1204.
