[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 706821, entitled “COLLISION HANDLING FOR PHYSICAL UPLINK CHANNELS,” filed September 11, 2020, and U.S. Non-Provisional Patent Application No. 17 / 447278, entitled “COLLISION HANDLING FOR PHYSICAL UPLINK CHANNELS,” filed September 9, 2021, which are expressly incorporated herein by reference. Technical Field

[0003] The aspects of this disclosure generally relate to wireless communications and techniques and apparatus for collision handling for physical uplink channels. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / improved LTE is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication between multiple user equipment (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, while an "uplink" (or "backlink") refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Head, Transmitter Receiver Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a universal protocol enabling different user equipment to communicate at the municipal, national, regional, and even global levels. NR (also known as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL), and using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0009] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a UE, cause the UE to: determine that multiple physical uplink channels scheduled for the UE overlap, wherein the multiple physical uplink channels include a first physical uplink channel and a second physical uplink channel associated with different priorities; and order or multiplex the transmission of at least one of the first physical uplink channel or the second physical uplink channel according to the priority of the first physical uplink channel and the second physical uplink channel, wherein the priority ordering or multiplexing is based at least in part on whether the UE is capable of simultaneously performing PUCCH and PUSCH transmissions.

[0010] In some aspects, an apparatus for wireless communication includes units for determining the overlap of a plurality of physical uplink channels scheduled for a UE, wherein the plurality of physical uplink channels include a first physical uplink channel and a second physical uplink channel associated with different priorities; and units for ordering or multiplexing transmission of at least one of the first physical uplink channel or the second physical uplink channel according to the priority of the first physical uplink channel and the second physical uplink channel, wherein the priority ordering or multiplexing is based at least in part on whether the apparatus is capable of performing PUCCH and PUSCH transmissions simultaneously.

[0022] Various aspects of this disclosure will be described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided to make this disclosure thorough and complete and to fully communicate the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect disclosed herein, whether implemented independently of or in combination with other aspects of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover an apparatus or method practiced using structures, functions, or structures and functions other than those set forth herein, or structures, functions, or structures and functions not used in connection with the various aspects set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0023] Several aspects of a telecommunications system will now be introduced with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0024] It should be noted that while the terms commonly associated with 5G or NR radio access technology (RAT) may be used to describe the aspects herein, the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0025] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network. The wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, Transmitter Receiver Point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a BS and / or the coverage area of ​​a BS subsystem serving that coverage area, depending on the context in which the term is used.

[0026] A Base Station (BS) can provide communication coverage for macrocells, picocells, femtocells, and / or other cell types. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allows unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and allows unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and allows restricted access for UEs associated with the femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A base station used for femtocells can be called a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femtocell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0027] In some respects, the cell may not be fixed, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs can interconnect with each other and / or connect to one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (e.g., direct physical connections or virtual networks).

[0028] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay BS can also be called a relay station, relay base station, relay, etc.

[0029] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs), such as macro BSs, pico BSs, femto BSs, and repeater BSs. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and repeater BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0030] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. The BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0031] UEs 120 (e.g., 120a, 120b, 120c) may be distributed across the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biosensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0032] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide or supply connectivity to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0033] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0034] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0035] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1), which spans from 410 MHz to 7.125 GHz, and / or can communicate using an operating band with a second frequency range (FR2), which spans from 24.25 GHz to 52.6 GHz. Frequency ranges between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "below 6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although this differs from the Extremely High Frequency (EHF) band (30 GHz–300 GHz) recognized as a "millimeter wave band" by the International Telecommunication Union (ITU). Therefore, unless otherwise specified, it should be understood that the terms "below 6 GHz" and the like (if used herein) can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise specified, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., below 24.25 GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0036] As mentioned above, Figure 1 Provided as an example. Other examples may be provided. Figure 1 The descriptions differ from those in the text.

[0037] Figure 2 This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0038] At base station 110, transmit processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process data for each UE (e.g., coding and modulation) based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). If applicable, the transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its own output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0039] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data of UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine parameters such as the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI. In some respects, one or more components of the UE 120 may be included in the housing 284.

[0040] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0041] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements in multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.

[0042] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmitting processor 264 can be pre-encoded by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator of UE 120 (e.g., MOD / DEMOD 254) can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264 and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 5-7 (As described).

[0043] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 5-7 (As described).

[0044] The controller / processor 240 of base station 110, the controller / controller 280 of UE 120 and / or Figure 2Any other components may perform one or more techniques associated with collision handling of the physical uplink channel, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / controller 280 of UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 6 The operation of process 600 and / or other processes described herein. Memory 242 and 282 may store data and program code of base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, transformation, and / or interpretation), one or more instructions may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 6 The operation of process 600 and / or other processes described herein. In some aspects, the execution instructions may include run instructions, translation instructions, compilation instructions, and / or interpretation instructions, etc.

[0045] In some aspects, the UE includes elements for determining that a first physical uplink channel is scheduled to overlap with a second physical uplink channel scheduled for the UE, wherein the first physical uplink channel and the second physical uplink channel are associated with different priorities; and / or elements for ordering or multiplexing transmission of at least one of the first physical uplink channel or the second physical uplink channel according to the priorities of the first physical uplink channel and the second physical uplink channel, wherein the priority ordering or multiplexing is based at least in part on whether the UE is capable of simultaneously performing physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmissions. Elements for the UE to perform the operations described herein may include, for example, an antenna 252, a demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a modulator 254, a controller / processor 280, and / or a memory 282.

[0047] In some aspects, the UE includes a unit for determining, at least in part, that the PUCCH and PUSCH satisfy the multiplexing timeline based on the determination that the PUCCH is scheduled to overlap with the PUSCH.

[0048] In some respects, the UE includes a unit for multiplexing PUCCH and PUSCH based at least in part on one of the following: determining that the identifier associated with the carrier used for PUSCH is the smallest identifier among different carriers, or determining whether PUCCH and PUSCH are associated with the same priority.

[0053] In some respects, the UE includes a unit for transmitting a result channel with one or more other PUSCHs on a carrier different from the primary cell, without regard to the priority associated with one or more other PUSCHs.

[0054] In some respects, the UE includes a unit for transmitting a result channel with one or more other PUSCHs on a carrier different from the primary cell, without regard to the priority associated with one or more other PUSCHs.

[0055] Although Figure 2 The blocks are shown as different components, but the functions described above regarding the blocks can be implemented in a single hardware, software, or combined component, or in different combinations of components. For example, the functions described regarding the transmit processor 264, receive processor 258, and / or TXMIMO processor 266 can be executed by the controller / processor 280 or under the control of the controller / processor 260.

[0056] As mentioned above, Figure 2 Provided as an example. Other examples may be found in the reference. Figure 2 The differences mentioned.

[0057] Figure 3 This is a diagram illustrating example 300 of carrier aggregation according to this disclosure.

[0058] Carrier aggregation is a technique that enables two or more component carriers (CCs, sometimes called carriers) to be combined (e.g., combined into a single channel) for a single UE 120 to enhance data capacity. As shown, carriers can be combined in the same or different frequency bands. Alternatively, contiguous or discontinuous carriers can be combined. Base station 110 can configure carrier aggregation for UE 120, for example, in Radio Resource Control (RRC) messages, Downlink Control Information (DCI), etc.

[0059] As shown by reference numeral 305, in some aspects, carrier aggregation can be configured as an intra-band continuous mode, wherein the aggregated carriers are continuous with each other and in the same frequency band. As shown by reference numeral 310, in some aspects, carrier aggregation can be configured as an intra-band discontinuous mode, wherein the aggregated carriers are discontinuous with each other and in the same frequency band. As shown by reference numeral 315, in some aspects, carrier aggregation can be configured as an inter-band discontinuous mode, wherein the aggregated carriers are discontinuous with each other and in different frequency bands.

[0060] In carrier aggregation, UE 120 can be configured with a primary carrier and one or more secondary carriers. In some aspects, the primary carrier can carry control information (e.g., downlink control information, scheduling information, etc.) for scheduling data communications on one or more secondary carriers; this can be referred to as cross-carrier scheduling. In other aspects, a carrier (e.g., a primary carrier or a secondary carrier) can carry control information for scheduling data communications on the carrier; this can be referred to as self-carrier scheduling or carrier self-scheduling.

[0061] In some cases, a group of carriers may form a PUCCH group. A “PUCCH group” can refer to a group of carriers that includes a primary carrier (e.g., primary cell (PCell)) and one or more secondary carriers (e.g., secondary cell (SCell)). The primary carrier can be used for all PUCCH communications for the PUCCH group.

[0062] Similar to carrier aggregation, some wireless communication systems allow dual connectivity for the UE to the network. For example, with dual connectivity, the UE can connect to the network via multiple cell groups, such as a primary cell group (MCG) and a secondary cell group (SCG). The primary cell group can include one or more serving cells associated with a primary node (MN), and the secondary cell group can include one or more serving cells associated with a secondary node (SN). Each SCG can include a primary and secondary cell (PSCell) and one or more SCcells. Dual connectivity via the MCG and SCG (each of which can be controlled by a different base station) can achieve improved connectivity, coverage, and bandwidth for the UE.

[0063] As mentioned above, Figure 3 Provided as an example. Other examples may be provided. Figure 3 The descriptions differ from those in the text.

[0064] Figure 4 These are diagrams illustrating examples 400 and 450 of overlapping uplink transmissions according to this disclosure.

[0065] In some communication systems, the UE can resolve conflicts by prioritizing physical uplink channels. For example, the UE can detect a second DCI format that schedules a physical uplink channel with low priority (e.g., a low-priority index). The UE can then detect a first DCI format that schedules a physical uplink channel with high priority (e.g., a high-priority index), where the high-priority physical uplink channel will at least partially overlap with the low-priority physical uplink channel. In this case, since the second DCI format is detected later (e.g., detection of the second DCI format occurs after the detection of the first DCI format), the UE may discard the low-priority physical uplink channel and may not want to transmit the low-priority physical uplink channel. Therefore, conflicts are resolved by discarding (i.e., avoiding transmission) the low-priority physical uplink channel.

[0066] In addition to the priority ordering techniques described above, in some cases, the UE can resolve conflicts by multiplexing physical uplink channels with the same priority. For example, the UE can be configured to multiplex a first physical uplink channel with low priority and a second physical uplink channel with low priority to resolve conflicts between a first physical uplink channel with low priority and a physical uplink channel with high priority (e.g., when the channel resulting from the multiplexing of the first and second low-priority physical uplink channels does not overlap with the high-priority physical uplink channel). In some cases, the timing of the uplink grant for scheduling physical uplink channels and / or the timing of the physical uplink channels themselves determines whether conflicts are resolved through priority ordering or by multiplexing physical uplink channels with the same priority.

[0067] As shown in Example 400, the first low-priority (LP) DCI can schedule LP PUCCH, the second high-priority (HP) DCI can schedule HP PUSCH, and the third LP DCI can schedule LP PUSCH. As illustrated, LP PUCCH and HP PUSCH can overlap, LP PUCCH and LP PUSCH can overlap, and HP PUSCH and LP PUCCH may not overlap. Therefore, the UE can determine to cancel the transmission of an LP PUCCH overlapping with an HP PUSCH before the first symbol of that overlapping LP PUCCH. Furthermore, the UE can anticipate that the transmission of a PUSCH will not occur within the PUSCH preparation time (T) corresponding to the UE's processing capacity. proc,2It begins before ) . However, it may be beneficial for the UE to maintain the contents of the LP PUCCH by multiplexing the LP channel.

[0068] As shown in Example 450, the UE can multiplex overlapping LP PUCCH and LP PUSCH on the PUSCH. That is, as described above, the UE can first multiplex channels with the same priority. As shown, the multiplexing of LP PUCCH and LP PUSCH resolves the conflict between LPPUCCH and HP PUSCH.

[0069] If LP PUCCH and LP PUSCH satisfy the definition Figure 4 Given a multiplexing timeline with a multiplexing deadline, the UE can multiplex overlapping LP PUCCH and LP PUSCH. The multiplexing timeline can be at least partially based on the UE's processing capabilities, and therefore the multiplexing deadline can be a specific time interval before the start of the first scheduled channel. If a DCI for a second scheduled channel is received at the UE before the multiplexing deadline, the UE can multiplex the overlapping second scheduled channel with the first scheduled channel.

[0070] As mentioned above, Figure 4 Provided as an example. Other examples may be provided. Figure 4 The descriptions differ from those in the text.

[0071] In some cases, wireless communication systems can prioritize and / or multiplex channels with different priorities. For example, if a PUCCH conflicts with a high-priority channel, the UE can discard the PUCCH carrying periodic channel state information (CSI). In some cases, the UE can receive an indication regarding whether to multiplex overlapping channels or discard one or more overlapping channels. This indication can be configured semi-statically for the UE or it can be a dynamic indication (e.g., in Layer 1 (L1) signaling).

[0072] In some cases, wireless communication systems can transmit PUCCH and PUSCH simultaneously, such as PUCCH and PUSCH on different carriers. In this case, the UE can avoid performing priority ordering and / or multiplexing (e.g., if overlapping channels can be transmitted simultaneously).

[0073] In some communication systems, such as 5G or NR, a UE can transmit communication to a base station on a physical uplink channel (e.g., PUCCH and / or PUSCH) in one or more time slots. In some cases, multiple communications can be scheduled (e.g., by the base station, the UE, and / or another entity in the communication system, etc.) to be transmitted by the UE in the same time slot. For example, a first communication can be scheduled to be transmitted by the UE in a time slot on a first PUCCH, and a second communication can be scheduled to be transmitted by the UE in a time slot on a second PUCCH. As another example, a first communication can be scheduled to be transmitted by the UE in a time slot on a PUCCH, and a second communication can be scheduled to be transmitted by the UE in a time slot on a PUSCH.

[0074] In some cases, the scheduling of multiple communications transmitted by a UE in the same time slot on different physical uplink channels may be termed a conflict. In some situations, the UE can be configured to apply complex rule sets to resolve conflicts. However, the UE may not be able to resolve situations involving different physical uplink channels associated with different priorities. For example, when the UE cannot perform PUCCH and PUSCH transmissions simultaneously, it may not be able to determine the priority ordering or multiplexing of overlapping physical uplink channels with different priorities. As another example, when the UE can perform PUCCH and PUSCH transmissions simultaneously, it may not be able to determine the priority or multiplexing of overlapping physical uplink channels with different priorities.

[0075] This document describes aspects that provide techniques and apparatus for conflict resolution between different physical uplink channels. In some aspects, the UE can determine that multiple physical uplink channels overlap. The UE can prioritize and / or multiplex one or more of the overlapping physical uplink channels for transmission. Furthermore, prioritization and / or multiplexing can be based at least in part on whether the UE can simultaneously perform PUCCH and PUSCH transmissions. In this way, the UE can resolve conflicts between different physical uplink channels, which increases the UE's reliability and operability, among other things.

[0076] Figure 5 This is a diagram illustrating example 500 associated with collision handling of a physical uplink channel according to this disclosure. Figure 5 As shown, Example 500 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network, such as wireless network 100. Base station 110 and UE 120 may communicate on a radio access link, which may include an uplink and a downlink.

[0077] In some aspects, UE 120 can be enabled (e.g., depending on the capabilities and / or configuration of UE 120) to perform simultaneous (e.g., concurrent or parallel) uplink transmissions (e.g., simultaneous PUCCH and PUSCH transmissions). Simultaneous uplink transmissions can be enabled for physical uplink channels associated with the same priority (e.g., PUCCH and PUSCH) or physical uplink channels associated with different priorities. In some aspects, the power scaling configuration of UE 120 can use the priority of uplink carrier aggregation transmissions.

[0078] In some respects, UE 120 may not be able to perform simultaneous uplink transmissions on physical uplink channels scheduled on the same carrier. However, it is possible to enable UE 120 to perform cross-carrier simultaneous uplink transmissions by combining inter-band carrier aggregation or intra-band carrier aggregation. In some respects, simultaneous uplink transmissions for intra-band carrier aggregation can be used for uplink transmissions with aligned start and end symbols to maintain phase continuity.

[0079] In some aspects, UE 120 may be configured (e.g., by base station 110) with multiple (e.g., two) cell groups (e.g., associated with the dual connectivity mode of UE 120). In some aspects, UE 120 may be configured (e.g., by base station 110) with multiple PUCCH groups (e.g., primary PUCCH group and secondary PUCCH group) for each cell group configured for UE 120.

[0080] In some respects, UE 120 may not be able to (e.g., depending on UE 120's capabilities and / or UE 120's configuration) perform priority ordering or multiplexing across carriers in different cell groups. In other respects, UE 120 may not be able to perform multiplexing across carriers in different PUCCH groups, but UE 120 may be able to perform priority ordering across all carriers in a cell group, regardless of whether these carriers are associated with a primary PUCCH group or a secondary PUCCH group.

[0081] In some aspects, UE 120 may be able to perform simultaneous uplink transmissions across multiple PUCCH groups (e.g., simultaneous PUCCH transmissions or simultaneous PUCCH and PUSCH transmissions). In some aspects, UE 120 may be able to perform simultaneous uplink transmissions across multiple cell groups.

[0082] Therefore, as described below, UE 120 can prioritize or multiplex overlapping physical uplink channels by PUCCH group (e.g., independently by PUCCH group). For example, UE 120 can perform first priority prioritization or multiplexing for primary PUCCH groups and second priority prioritization or multiplexing for secondary PUCCH groups. Furthermore, as described below, UE 120 can prioritize or multiplex overlapping physical uplink channels by cell group (e.g., independently by cell group). For example, UE 120 can perform first priority prioritization or multiplexing for primary cell groups and second priority prioritization or multiplexing for secondary cell groups.

[0083] As shown by reference numeral 505 in the accompanying drawings, base station 110 can transmit scheduling for multiple physical uplink channels, and UE 120 can receive scheduling for multiple physical downlink channels. For example, UE 120 can receive one or more DCI messages scheduling (e.g., in one or more uplink grants) one or more physical uplink channels (e.g., one or more PUCCHs and / or one or more PUSCHs, etc.) for UE 120. As an example, UE 120 can receive scheduling for one or more PUCCHs (e.g., one or more PUCCH transmissions) and scheduling for one or more PUSCHs (e.g., one or more PUSCH transmissions). In some aspects, UE 120 can receive one or more configurations for scheduling one or more physical uplink channels for UE 120. For example, UE 120 can receive grants for configurations that schedule periodic PUCCHs and / or PUSCHs for UE 120.

[0084] In some respects, UE 120 can use PUCCH to transmit uplink control information, such as acknowledgments and / or CSI. In other respects, UE 120 can use PUSCH to transmit user data and / or uplink control information.

[0085] In some respects, one or more physical uplink channels scheduled for UE 120 may be associated with Ultra Reliable Low Latency Communication (URLLC). For example, one or more physical uplink channels scheduled for UE 120 may be assigned a relatively high priority (e.g., a high priority index) via DCI or configuration. Similarly, one or more physical uplink channels scheduled for UE 120 may be assigned a relatively low priority.

[0086] As shown by reference numeral 510 in the accompanying drawings, UE 120 may determine that at least one physical uplink channel scheduled for UE 120 overlaps with at least one other physical uplink channel scheduled for UE 120 (e.g., partially or completely overlap in time). For example, UE 120 may determine that at least one PUCCH scheduled for UE 120 overlaps with at least one PUSCH scheduled for UE 120 (e.g., conflict). UE 120 may determine that the PUCCH and PUSCH overlap in time, for example, when the PUCCH and PUSCH are scheduled in one or more of the same symbols, or in one or more of the same time slots, etc. In some aspects, UE 120 may determine that one or more first PUCCHs scheduled for UE 120 overlap with one or more second PUCCHs scheduled for UE 120. In some aspects, the overlapping physical uplink channels may be associated with different priorities (e.g., high priority and low priority).

[0087] As shown by reference numeral 515 in the attached figure, UE 120 can determine the priority ordering or multiplexing of overlapping physical uplink channels. For example, UE 120 can determine the priority ordering or multiplexing of one or more overlapping PUCCHs and one or more PUSCHs, or multiple overlapping PUCCHs. In some aspects, overlapping physical uplink channels can be associated with corresponding priorities (e.g., high priority or low priority, etc.), and UE 120 can determine the priority ordering at least partially based on these priorities. In some aspects, UE 120 can determine to discard lower-priority physical uplink channels. In some aspects, UE 120 can determine to multiplex at least one PUCCH with at least one PUSCH. In some aspects, UE 120 can determine to multiplex at least one PUCCH with at least one other PUCCH. In some aspects, the priority ordering or multiplexing of overlapping physical uplink channels can be based at least partially on whether UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions.

[0088] In some cases, UE 120 may not be able to perform PUCCH and PUSCH transmissions simultaneously. Furthermore, UE 120 may determine that a PUCCH overlaps with multiple PUSCHs (e.g., conflicts) and may schedule multiple PUSCHs on different carriers (e.g., each PUSCH may be scheduled on a corresponding carrier, or at least two of the PUSCHs may be scheduled on different carriers). In some respects, the PUCCH and one or more of the multiple PUSCHs may be associated with different priorities.

[0089] In some aspects, UE 120 can perform multiplexing on physical uplink channels with different priorities, and when simultaneous PUCCH and PUSCH transmission is not enabled. In some aspects, UE 120 can multiplex PUCCH with overlapping PUSCHs among multiple PUSCHs on a carrier for PUSCH. For example, as described above, UE 120 can multiplex PUCCH with overlapping PUSCHs on a carrier, at least in part, based on the determination of the multiplexing timeline by which the scheduling of PUCCH and PUSCH satisfies the multiplexing timeline.

[0090] In some cases, UE 120 can determine that multiple PUSCHs overlapping with the PUCCH (e.g., all PUSCHs or a subset of the multiple PUSCHs) satisfy a multiplexing timeline. Here, UE 120 can multiplex the PUCCH with one of the multiple PUSCHs based at least in part on the respective priorities associated with the multiple PUSCHs and / or the identifiers (e.g., index values) associated with the respective carriers of the multiple PUSCHs. For example, UE 120 can multiplex the PUCCH with a PUSCH associated with the same priority as the PUCCH (e.g., firstly, to resolve conflicts). As another example, UE 120 can multiplex the PUCCH with a PUSCH scheduled on the carrier associated with the smallest identifier (e.g., index value) among the multiple PUSCHs (e.g., if no PUSCH among the multiple PUSCHs or more than one of the multiple PUSCHs is associated with the same priority as the PUCCH).

[0091] In some respects, UE 120 can determine (e.g., expect) that a scheduled PUCCH overlaps with a scheduled PUSCH that satisfies the multiplexing timeline (e.g., if a scheduled PUCCH overlaps with a scheduled PUCCH that does not satisfy the multiplexing timeline, UE 120 can determine an error). Therefore, as described above, UE 120 can multiplex a PUCCH with one of a plurality of overlapping PUSCHs, at least in part, based on the respective priorities associated with the plurality of PUSCHs and / or the identifiers associated with the respective carriers of the plurality of PUSCHs. For example, UE 120 can multiplex a PUCCH on a carrier associated with a minimum identifier and having the same priority as the PUCCH. If no overlapping PUSCH with the same priority as the PUCCH exists, UE 120 can multiplex the PUCCH and PUSCH on a carrier associated with the minimum identifier.

[0092] In some cases, UE 120 may determine that multiple PUCCHs overlap with multiple PUSCHs scheduled on different carriers (e.g., each PUSCH may be scheduled on its own carrier, or at least two PUSCHs may be scheduled on different carriers). For example, multiple PUCCHs scheduled on a PCell or PSCell (e.g., non-overlapping PUCCHs) may each overlap with PUSCHs scheduled on one or more SCells. Here, as described above, UE 120 may perform its own (e.g., separate) multiplexing for each of the multiple PUCCHs. For example, UE 120 may multiplex a first PUCCH with a PUSCH from the multiple PUSCHs (e.g., using the criteria described above), multiplex a second PUCCH with a PUSCH from the multiple PUSCHs (e.g., the same PUSCH multiplexed with the first PUCCH, or a different PUSCH), and so on.

[0093] In some cases, UE 120 can determine that some PUCCHs overlapping with multiple PUSCHs are associated with the same priority. Here, UE 120 can multiplex PUCCHs with the same priority with the same PUSCH (e.g., using the criteria described above). In other words, UE 120 can determine the same carrier and the same PUSCH used for multiplexing PUCCHs with the same priority. Therefore, UE 120 can make a single determination that can be applied to each PUCCH with the same priority.

[0094] In some cases, UE 120 may determine that the PUCCH overlaps with multiple PUSCHs on the same carrier (e.g., as described above, UE 120 selects a carrier for multiplexing the PUCCH). In some aspects, UE 120 may multiplex the PUCCH on the first (e.g., in time) PUSCH among multiple PUSCHs. Additionally or alternatively, UE 120 may multiplex the PUCCH on the first PUSCH among multiple PUSCHs that satisfies the multiplexing timeline with the PUCCH. In some aspects, UE 120 may multiplex the PUCCH on each of the multiple PUSCHs (e.g., on all of the multiple PUSCHs). Additionally or alternatively, UE 120 may multiplex the PUCCH on each of the multiple PUSCHs that satisfies the multiplexing timeline with the PUCCH (e.g., on all of the multiple PUSCHs that satisfy the multiplexing timeline). In some aspects, multiple PUSCHs may be associated with different priorities. For example, some of the multiple PUSCHs may be of high priority, while some of the multiple PUSCHs may be of low priority. Therefore, as described above, UE120 can multiplex PUCCH with one or more of a plurality of PUSCHs that are associated with the same priority as PUCCH.

[0095] In some cases, UE 120 can determine that multiple PUCCHs (e.g., with the same or different priorities) overlap on a PCell. Furthermore, UE 120 can determine that overlapping PUCCHs also overlap with one or more PUSCHs on the same or different carriers. Here, as described above, UE 120 can perform multiplexing for each PUCCH of a specific priority (e.g., independently). For example, UE 120 can multiplex a first PUCCH of a first priority with a PUSCH (e.g., using the criteria described above), multiplex a second PUCCH of a second priority with a PUSCH (e.g., the same PUSCH multiplexed with the first PUCCH, or a different PUSCH), and so on.

[0096] In some aspects, UE 120 can multiplex multiple overlapping PUCCHs before multiplexing multiple PUCCHs with PUSCHs. In other words, as described above, UE 120 can first multiplex multiple PUCCHs and then multiplex the multiplexed PUCCHs with PUSCHs. In some aspects, UE 120 can multiplex the multiplexed PUCCHs with high-priority PUSCHs on the carrier associated with the minimum identifier (e.g., because high priority can be assigned to one or more multiplexed PUCCHs). If no high-priority PUSCH exists on the carrier associated with the minimum identifier, UE 120 can multiplex the multiplexed PUCCHs with low-priority PUSCHs on the carrier associated with the minimum identifier.

[0097] In some cases, UE 120 may be able to perform simultaneous PUCCH and PUSCH transmissions. Furthermore, UE 120 can determine that a PUCCH overlaps with a PUSCH or another PUCCH (e.g., a conflict). In some respects, PUCCH and PUSCH may be associated with different priorities, and / or PUCCH may be associated with different priorities from other PUCCHs.

[0098] In some aspects, when UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions (e.g., simultaneous PUCCH and PUSCH transmissions on different carriers), UE 120 can perform priority ordering on physical uplink channels with different priorities. In some aspects, UE 120 can perform priority ordering only on a single carrier (e.g., PCell or PSCell) on which physical uplink channels overlap, and can avoid performing priority ordering on one or more other carriers on which physical uplink channels overlap (e.g., UE 120 can prioritize overlapping physical uplink channels on a single carrier and avoid prioritizing overlapping physical uplink channels across carriers). UE 120 can perform priority ordering by (e.g., using 3GPP Release 16 URLLC priority ordering rules) determining to transmit higher-priority channels and to discard lower-priority channels.

[0099] For example, UE 120 can handle a conflict between a PUCCH and another PUCCH on a single carrier to obtain a resulting channel by prioritizing PUCCHs and other PUCCHs (and discarding lower-priority PUCCHs). As another example, UE 120 can handle a conflict between a PUCCH and a PUSCH on a single carrier to obtain a resulting channel by prioritizing PUCCHs and PUSCHs (and discarding one of the PUCCHs or PUSCHs associated with a lower priority). In some aspects, UE 120 can use PUSCHs scheduled on a carrier other than a single carrier (e.g., PCell) to transmit the resulting channel, regardless of the priority associated with the PUSCH (e.g., because UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions on different carriers).

[0100] In some cases, UE 120 can be configured to use a single PUCCH group, and UE 120 can perform priority ordering on a single carrier (e.g., PCell) of the PUCCH group, as described above. In other cases, UE 120 can be configured to use multiple (e.g., two) PUCCH groups. Here, UE 120 may be able to perform simultaneous PUCCH and PUSCH transmissions on different carriers of each PUCCH group, and as described above, UE 120 can perform priority ordering on each PUCCH group. That is, as described above, UE 120 can perform priority ordering on a single carrier (e.g., PCell) for the first PUCCH group, and UE 120 can independently perform priority ordering on a single carrier for the second PUCCH group.

[0101] In some aspects, when UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions (e.g., simultaneous PUCCH and PUSCH transmissions on different carriers), UE 120 can perform multiplexing on physical uplink channels with different priorities. In some aspects, UE 120 can perform multiplexing only on a single carrier (e.g., PCell or PSCell) on which physical uplink channels overlap, and can avoid multiplexing on one or more other carriers on which physical uplink channels overlap (e.g., UE 120 can multiplex overlapping physical uplink channels on a single carrier and avoid multiplexing overlapping uplink channels across carriers).

[0102] For example, UE 120 can resolve conflicts between a PUCCH and another PUCCH on a single carrier to obtain a resulting channel by multiplexing PUCCH and other PUCCHs. As another example, UE 120 can resolve conflicts between a PUCCH and a PUSCH on a single carrier to obtain a resulting channel by multiplexing PUCCH and PUSCH. In some respects, UE 120 can use PUSCHs scheduled on carriers different from the single carrier to transmit the resulting channel, regardless of the priority associated with the PUSCH (e.g., because UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions on different carriers).

[0103] In some respects (e.g., when UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions), as described above, UE 120 can multiplex PUCCH and PUSCH on a PUSCH carrier (e.g., multiplexing is not limited to a single carrier). For example, as described above, UE 120 can multiplex PUCCH and PUSCH at least in part based on whether PUCCH and PUSCH meet a multiplexing timeline, whether PUSCH is associated with the same priority as PUCCH, and / or whether the carrier for PUSCH is associated with a minimum identifier.

[0104] In some respects, UE 120 can avoid multiplexing one or more PUCCHs with PUSCHs (e.g., because UE 120 is capable of performing simultaneous PUCCH and PUSCH transmissions). For example, UE 120 can multiplex one or more low-priority PUCCHs with PUSCHs (as described above), and UE 120 can avoid multiplexing one or more high-priority PUCCHs (which would be transmitted in parallel with the multiplexed PUSCHs). In some respects, UE 120 may be configured with or otherwise equipped with one or more rules for determining whether a PUCCH should be multiplexed with a PUSCH, or whether a PUCCH should be transmitted in parallel with another PUCCH.

[0105] In some cases, UE 120 can be configured to use a single PUCCH group, and UE 120 can perform multiplexing on a single carrier (e.g., PCell) or multiple carriers of the PUCCH group, as described above. In other cases, UE 120 can be configured to use multiple (e.g., two) PUCCH groups. Here, UE 120 may be able to perform simultaneous PUCCH and PUSCH transmissions on different carriers of each PUCCH group, and as described above, UE 120 can perform multiplexing for each PUCCH group. That is, as described above, UE 120 can perform priority ordering for the first PUCCH group on a single carrier (e.g., PCell) or multiple carriers, and UE 120 can independently perform multiplexing for the second PUCCH group on a single carrier (e.g., PCell) or multiple carriers.

[0106] As shown by reference numeral 520 in the attached figure, according to the priority ordering or multiplexing determined by UE 120, UE 120 can transmit one or more overlapping physical uplink channels, and base station 110 can receive one or more overlapping uplink channels. For example, UE 120 can transmit one or more overlapping PUCCH and / or PUSCH according to the priority ordering or multiplexing determined by UE 120. In this way, the UE can resolve conflicts between different physical uplink channels, which increases the reliability and operability of the UE.

[0107] In some respects, base station 110 can also determine physical uplink channel overlap (e.g., collision) scheduled by UE 120. Here, base station 110 can determine that UE 120 performed prioritization and / or multiplexing to resolve the collision. Base station 110 can use the same criteria described above to determine the prioritization and / or multiplexing used by UE 120. Therefore, base station 110 can receive and decode physical uplink channels transmitted by UE 120 based at least in part on the prioritization and / or multiplexing used by UE 120.

[0108] As mentioned above, Figure 5 Provided as an example. Other examples may be provided. Figure 5 The descriptions differ from those in the text.

[0109] Figure 6 This is a diagram illustrating an example process 600 performed by a UE, for example, according to this disclosure. Example process 600 is an example of an operation performed by a UE (e.g., UE 120) associated with collision handling of the physical uplink channel.

[0110] like Figure 6As shown, in some aspects, process 600 may include determining that a first physical uplink channel is scheduled to overlap with a second physical uplink channel scheduled for the UE, wherein the first physical uplink channel and the second physical uplink channel are associated with different priorities (block 610). For example, the UE (e.g., using...)
