Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communication, and to techniques and apparatus for dynamic multiplexing and prioritization to resolve conflicts in physical uplink channels. Background Technology

[0004] Wireless communication systems have been 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 enable 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 collection 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 one or more base stations that support communication for one or more user equipment (UEs). UEs can communicate with base stations via downlink and uplink communication. Downlink (or "DL") refers to the communication link from the base station to the UE, and uplink (or "UL") refers to the communication link from the UE to the base station.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate across city, country, region, and / or global scales. New Radio (NR) (also known as 5G) is a set of evolutions of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, enhancing service, fully utilizing new spectrum, using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink, better integrating with other open standards, and 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 one or more instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a UE, cause the one or more processors to: receive a multiplexing indication for indicating that a first high-priority physical uplink channel scheduled in a first resource set is to be multiplexed with a low-priority physical uplink channel scheduled in a second resource set, the first resource set and the second resource set at least partially overlapping; receive a priority indication associated with a second high-priority physical uplink channel scheduled in a third resource set, the third resource set at least partially overlapping the second resource set; and transmit one or more physical uplink channels according to the priority or multiplexing, the one or more physical channels including at least the second high-priority physical uplink channel, wherein the priority or the multiplexing is at least partially based on the multiplexing indication or the priority indication.

[0010] In some aspects, an apparatus for wireless communication includes: a unit for receiving a multiplexing indication for indicating that a first high-priority physical uplink channel scheduled in a first resource set is to be multiplexed with a low-priority physical uplink channel scheduled in a second resource set, the first and second resource sets at least partially overlapping; a unit for receiving a priority indication associated with a second high-priority physical uplink channel scheduled in a third resource set, the third resource set at least partially overlapping with the second resource set; and a unit for transmitting one or more physical uplink channels according to priority or multiplexing, the one or more physical channels including at least the second high-priority physical uplink channel, wherein the priority or multiplexing is at least partially based on the multiplexing indication or the priority indication.

However, this disclosure may be implemented in many different forms and should not be construed as limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided only to make this disclosure thorough and complete and to fully convey the scope of protection of this disclosure to those skilled in the art. It should be understood by those skilled in the art that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently or in combination with any other aspect of this disclosure.

It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0021] The following describes some aspects of a telecommunications system with reference to various devices and techniques. These devices and techniques will be described in the following detailed embodiments and depicted in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0022] While this document uses terms commonly associated with 5G or New Radio (NR) Radio Access Technology (RAT) to describe its aspects, the aspects of this disclosure may also be applied to other RATs (e.g., 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G)).

[0023] Figure 1This is a schematic diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G network (e.g., a Long Term Evolution (LTE) network), etc., or may include elements of a 5G (e.g., NR) network and / or a 4G network (e.g., a Long Term Evolution (LTE) network), etc. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and one or more user equipment (UE) 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e). Base station 110 is the entity that communicates with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a Transmitter-Receiver Point (TRP). Each base station 110 can provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term "cell" is used, the term "cell" can refer to the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area.

[0024] Base station 110 can provide communication coverage for macro cells, pico cells, femtocells, and / or another type of cell. A macro cell can cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access for UE 120 with a service subscription. A pico cell can cover a relatively small geographical area and can allow unrestricted access for UE 120 with a service subscription. A femtocell can cover a relatively small geographical area (e.g., a home) and can allow restricted access for UE 120 associated with that femtocell (e.g., UE 120 in a closed user group (CSG)). Base station 110 for macro cells can be referred to as a macro base station. Base station 110 for pico cells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS 110a can be a macro base station for macro cell 102a, BS 110b can be a pico base station for pico cell 102b, and BS 110c can be a femto base station for femto cell 102c. A base station can support one or more (e.g., three) cells.

[0025] In some examples, the cell does not need to be stationary, and the geographical area of ​​the cell can move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base stations 110 can use any suitable transport network to interconnect with each other and / or interconnect to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections or virtual networks).

[0026] Wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., base station 110 or UE 120) and transmit those data to a downstream station (e.g., UE 120 or base station 110). A relay station may also be a UE 120 capable of relaying transmissions from other UEs 120. Figure 1 In the example shown, BS110d (e.g., a relay base station) can communicate with BS110a (e.g., a macro base station) and UE 120d to facilitate communication between BS110a and UE 120d. The base station 110 for relay communication can also be referred to as a relay station, relay base station, repeater, etc.

[0027] Wireless network 100 can be a heterogeneous network comprising different types of base stations (e.g., macro base stations, pico base stations, femto base stations, relay base stations, etc.). These different types of base stations 110 can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro base stations can have higher transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0028] Network controller 130 can be coupled to a set of base stations 110 and provide coordination and control for these base stations 110. Network controller 130 can communicate with base stations 110 via a backhaul communication link. Base stations 110 can also communicate directly with each other or indirectly via a wireless backhaul link or a wired backhaul link.

[0029] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may also include, for example, access terminals, terminals, mobile stations, and / or user units. UE 120 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 device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric authentication device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio device), an in-vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, and / or any other suitable device configured to communicate via a wireless medium.

[0030] Some UEs 120 can be viewed as machine-type communication (MTC) UEs or evolved or enhanced machine-type communication (eMTC) UEs. For example, MTC UEs and / or eMTC UEs may include robots, drones, remote devices, sensors, meters, monitors, and / or location tags capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 can be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs 120 can be considered customer premises equipment. UEs 120 may be included in a housing that houses the components of the UE 120 (e.g., processor components and / or memory components). In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electrically coupled, and / or electronically coupled.

[0031] Typically, any number of wireless networks 100 can be deployed within a given geographical area. Each wireless network 100 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 within a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5GRAT networks can be deployed.

[0032] In some examples, 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 device). For example, UEs 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, vehicle-to-infrastructure (V2I) protocols, etc.) and / or mesh networks. In such examples, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein, performed by base station 110.

[0033] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency range names FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, in various documents and articles, FR1 is often (interchangeably) referred to as the “below 6GHz” band. Similar naming issues sometimes arise regarding FR2; although it differs from the extremely high frequency (EHF) band (30GHz–300GHz), it is often (interchangeably) referred to in documents and articles as the “millimeter wave” band, which is identified as such by the International Telecommunication Union (ITU).

[0034] The frequencies between FR1 and FR2 are generally referred to as intermediate frequencies (IFs). Recent 5G NR studies have identified the operating bands of these IFs as the frequency range name FR3 (7.125GHz–24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to the IF. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6GHz. For example, three higher operating bands have been identified as the frequency range names FR4a or FR4–1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0035] Considering the examples above, unless otherwise specifically stated, it should be understood that when the term "below 6 GHz" is used herein, it can broadly refer to frequencies that are less than 6 GHz, within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that when the term "millimeter wave" is used herein, it can broadly refer to frequencies that may include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is anticipated that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0036] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0037] Figure 2 This is a schematic diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with antenna sets 234a to 234t such as T (T≥1) antennas, and the UE 120 may be equipped with antenna sets 252a to 252r such as R (R≥1) antennas.

[0038] At base station 110, transmit processor 220 can receive data for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 can select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on a channel quality indicator (CQI) received from the UE. UE 120 can process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmit processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS), demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​these data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and provide a set of output symbol streams (e.g., T output symbol streams) to a set of corresponding modems 232 (e.g., T modems, shown as modems 232a to 232t). Each modem 232 can use a corresponding modulator component to process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process (e.g., convert to analog signal, amplify, filter, and / or up-convert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a set of corresponding antennas 234 (e.g., T antennas, shown as 234a to 234t).

[0039] At UE 120, an antenna set (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110, and can provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems, shown as modems 254a to 254r). For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process these input samples (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control and system information to the 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 Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, 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. For example, network controller 130 may include one or more devices in the core network. Network controller 130 may communicate with base station 110 via communication unit 294.

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

[0042] On the uplink, at UE 120, transmit processor 264 can receive data from data source 262 and control information (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280, and process the data and control information. Transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by modulator 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted back to base station 110. In some examples, modem 254 of UE 120 may include modulator and demodulator. In some examples, UE 120 includes a transceiver. This transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The processor (e.g., controller / processor 280) and memory 282 may use a transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figures 4A-4C and Figure 5 (As described).

[0043] At base station 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by demodulator 232 (e.g., demodulator component, shown as DEMOD of modem 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 decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The processor (e.g., controller / processor 240) and memory 242 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figures 4A-4C and Figure 5 (As described).

[0044] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other components may implement one or more techniques associated with dynamic multiplexing and prioritization for resolving conflicts in the physical uplink channel, as described in further detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 5 The operation of process 500 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, 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 said one or more instructions are executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, transformation, and / or interpretation), they may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

In some examples, execution instructions may include run instructions, transformation instructions, compilation instructions, and / or interpretation instructions, etc.

[0045] In some aspects, the UE (e.g., UE 120) may include: a unit for receiving a multiplexing indication indicating that a first high-priority physical uplink channel scheduled in a first resource set is to be multiplexed with a low-priority physical uplink channel scheduled in a second resource set, the first and second resource sets at least partially overlapping; a unit for receiving a prioritization indication associated with a second high-priority physical uplink channel scheduled in a third resource set, the third and second resource sets at least partially overlapping; and / or a unit for transmitting one or more physical uplink channels according to prioritization or multiplexing, the one or more physical channels including at least the second high-priority physical uplink channel, wherein prioritization or multiplexing is at least partially based on the multiplexing indication or the prioritization indication. Units for the UE 120 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, UE 120 includes: a unit for discarding a low-priority physical uplink channel; a unit for discarding a first high-priority physical uplink channel; and / or a unit for transmitting a second high-priority physical uplink channel.

[0048] In some aspects, UE 120 includes: a unit for multiplexing a first high-priority physical uplink channel and a second high-priority physical uplink channel; and / or a unit for transmitting a low-priority physical uplink channel based at least in part on a determination that the resource set of the channel generated by multiplexing the first high-priority physical uplink channel and the second high-priority physical uplink channel does not overlap with a second resource set.

[0049] In some aspects, UE 120 includes: an element for transmitting a Physical Uplink Shared Channel (PUSCH) on a secondary cell simultaneously with transmitting one or more Physical Uplink Channels, the one or more Physical Uplink Channels being transmitted on the primary cell.

[0050] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of controller / processor 280.

[0051] As pointed out above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0052] Figure 3 This is a schematic diagram illustrating example 300 of carrier aggregation according to the present disclosure.

[0053] Carrier aggregation is a technique for combining two or more component carriers (CCs, sometimes referred to as carriers) for a single UE 120 (e.g., combining them into a single channel) 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 and / or Downlink Control Information (DCI).

[0054] As shown by reference numeral 305, in some aspects, carrier aggregation can be configured in 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 in 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 in an inter-band discontinuous mode, wherein the aggregated carriers are discontinuous with each other and in different frequency bands.

[0055] In carrier aggregation, UE 120 can be configured with a primary carrier and one or more secondary carriers. In some aspects, the primary carrier may carry control information (e.g., downlink control information and / or scheduling information) for scheduling data communications on one or more secondary carriers; this can be referred to as cross-carrier scheduling. In some aspects, a carrier (e.g., a primary carrier or a secondary carrier) may carry control information for scheduling data communications on that carrier; this can be referred to as self-carrier scheduling or carrier self-scheduling.

[0056] In some cases, carrier groups can form Physical Uplink Control Channel (PUCCH) groups. A “PUCCH group” can refer to a group of carriers that includes a primary carrier (e.g., PCell) and one or more secondary carriers (e.g., SCell). The primary carrier can be used for all PUCCH communications within the PUCCH group.

[0057] 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). An MCG may include one or more serving cells associated with a primary node (MN), and an SCG may include one or more serving cells associated with a secondary node (SN). Each SCG may include a primary secondary cell (PSCell) and one or more secondary cells (SCells). Dual connectivity via MCG and SCG (each of which can be controlled by different base stations) can achieve improved connectivity, coverage, and bandwidth for the UE.

[0058] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0059] In communication systems such as 5G or NR, a UE can transmit communication to a base station on physical uplink channels (e.g., PUCCH, Physical Uplink Shared Channel (PUSCH), etc.) within a time slot set. In some cases, communication groups can be scheduled on physical uplink channels that the UE wants to transmit on in at least partially overlapping time slot sets (e.g., scheduled by the base station, the UE, or another entity in the communication system). For example, a first communication can be scheduled to be transmitted on a first PUCCH in a first time slot set, and a second communication can be scheduled to be transmitted on a second PUCCH in a second time slot set that at least partially overlaps with the first time slot set. As another example, a first communication can be scheduled to be transmitted on a PUCCH in a first time slot set, and a second communication can be scheduled to be transmitted on a PUSCH in a second time slot set that at least partially overlaps with the first time slot set. Scheduling physical uplink channel groups in at least partially overlapping time slot sets can be referred to as a collision.

[0060] In some communication systems, UEs can resolve conflicts by prioritizing physical uplink channels. For example, a 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., after the first DCI format is detected), 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.

[0061] In addition to the prioritization 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 uplink permission for scheduling physical uplink channels and / or the timing indication of the physical uplink channels themselves may be used to resolve conflicts by prioritizing or multiplexing physical uplink channels with the same priority.

[0062] In some communication systems, the UE can also resolve conflicts by multiplexing physical uplink channels with different priorities (in addition to allowing the UE to prioritize physical uplink channels with different priorities and / or multiplex physical uplink channels with the same priority, as described above). Therefore, for a given conflict, the UE may need to determine whether to perform multiplexing of physical uplink channels with different priorities or to perform priority of physical uplink channels with different priorities.

[0063] In some cases, the decision of whether the UE should perform multiplexing or prioritization of physical uplink channels with different priorities can be made dynamically, for example, based on signaling indicating whether prioritization or multiplexing should be applied to overlapping physical uplink channels (e.g., Layer 1 (L1) signaling). In some cases, the UE's decision on whether to perform multiplexing or prioritization can be configured for some transmissions, such as scheduling requests, PUSCH or PUCCH in response to the configuration of a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), and other examples. However, in some cases, the UE may receive conflicting indications. For example, the UE may receive a first indication indicating that a first high-priority physical uplink channel should be multiplexed with a low-priority physical uplink channel, and then may receive a prioritization indication indicating that a second high-priority physical uplink channel should take precedence over the low-priority physical uplink channel. In such cases, the UE needs to determine whether to perform multiplexing and / or prioritization in conjunction with the transmission of the first high-priority physical uplink channel, the low-priority physical uplink channel, and / or the second high-priority physical uplink channel.

[0064] Furthermore, in some communication systems, UEs may be allowed to transmit PUCCH and PUSCH simultaneously on different carriers. In such cases, decisions regarding whether to perform multiplexing and / or prioritization associated with resolving conflicts between physical uplink channels with different priorities may be affected. That is, in some situations, whether a UE performs multiplexing and / or prioritization may depend on whether the UE is allowed to transmit PUCCH and PUSCH simultaneously.

[0065] The aspects described herein provide techniques and apparatus for dynamic multiplexing and prioritization to resolve conflicts in physical uplink channels. In some aspects, the UE may receive a multiplexing indication indicating that a first high-priority physical uplink channel scheduled in a first resource set is to be multiplexed with a low-priority physical uplink channel scheduled in a second resource set, wherein the first and second resource sets at least partially overlap. The UE may also receive a prioritization indication associated with a second high-priority physical uplink channel scheduled in a third resource set, wherein the third and second resource sets at least partially overlap. Here, the UE can transmit one or more physical uplink channels based on prioritization or multiplexing, wherein the one or more physical channels include at least the second high-priority physical uplink channel. In some aspects, prioritization or multiplexing is at least partially based on the multiplexing indication or the prioritization indication. In this way, the UE can dynamically resolve conflicts between different physical uplink channels with conflict indications, which increases the reliability and / or operability of the UE.

[0066] Figures 4A-4C This is a schematic diagram associated with example 400 of dynamic multiplexing and prioritization for resolving conflicts in the physical uplink channel, based on the content of this disclosure. Figure 4A As shown, Example 400 includes communication between UE 120 and a base station. In some aspects, UE 120 and base station 110 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.

[0067] As in Figure 4A As shown by reference numeral 405 in the accompanying drawing, UE 120 can receive information on scheduling low-priority physical uplink channels in a resource set. For example, UE 120 can receive a DCI indicating that a low-priority physical uplink channel is scheduled in a resource set. In some aspects, the DCI can indicate that the physical uplink channel is a low-priority physical uplink channel. In some aspects, the low-priority physical uplink channel can be a PUCCH or a PUSCH.

[0068] As shown by reference numeral 410 in the attached figure, UE 120 may receive information regarding the scheduling of a first high-priority physical uplink channel in a resource set, wherein the resource set in which the first high-priority physical uplink channel is scheduled overlaps at least partially with the resource set in which a low-priority physical uplink channel is scheduled (e.g., causing a conflict between the first high-priority physical uplink channel and the low-priority physical uplink channel). For example, UE 120 may receive a DCI indicating the scheduling of the first high-priority physical uplink channel in the resource set. In some aspects, the DCI may indicate that the physical uplink channel is a high-priority physical uplink channel. In some aspects, the first high-priority physical uplink channel may be a PUCCH or a PUSCH.

[0069] As further illustrated by reference numeral 410 in the accompanying drawing, UE 120 receives a multiplexing indication indicating that a first high-priority physical uplink channel should be multiplexed with a low-priority physical uplink channel. For example, the DCI scheduling the first high-priority physical uplink channel may include the multiplexing indication. In some aspects, the multiplexing indication indicates that the first high-priority physical uplink channel should be multiplexed with overlapping low-priority physical uplink channels and / or overlapping high-priority physical uplink channels.

[0070] As shown by reference numeral 415 in the attached figure, UE 120 can receive information on scheduling a second high-priority physical uplink channel in a resource set, wherein the resource set in which the second high-priority physical uplink channel is scheduled overlaps at least partially with the resource set in which a low-priority physical uplink channel is scheduled (e.g., causing a conflict between the second high-priority physical uplink channel and the low-priority physical uplink channel). For example, UE 120 can receive a DCI indicating that the second high-priority physical uplink channel is scheduled in the resource set. In some aspects, the DCI may indicate that the physical uplink channel is a high-priority physical uplink channel. In some aspects, the second high-priority physical uplink channel may be a PUCCH or a PUSCH.

[0071] As further illustrated by reference numeral 415 in the accompanying drawing, UE 120 receives a priority indication that a second higher priority physical uplink channel takes precedence over a lower priority physical uplink channel. For example, the DCI that schedules the second higher priority physical uplink channel may include the priority indication. In some aspects, the priority indication is used to indicate that the second higher priority physical uplink channel takes precedence over overlapping lower priority physical uplink channels.

[0072] In some aspects, after UE 120 receives a multiplexing indication associated with a first high-priority physical uplink channel, UE 120 receives a priority indication associated with a second high-priority physical uplink channel. For example, the second high-priority physical uplink channel may be scheduled in the time domain after the first high-priority physical uplink channel. Figure 4B The diagram illustrates the following situation: After UE 120 receives a multiplexing indication associated with the first high-priority physical uplink channel, UE 120 receives a priority indication associated with the second high-priority physical uplink channel.

[0073] In some aspects, after UE 120 receives a prioritization indication associated with a second high-priority physical uplink channel, UE 120 receives a multiplexing indication associated with a first high-priority physical uplink channel. For example, the first high-priority physical uplink channel may be scheduled in the time domain after the second high-priority physical uplink channel. Figure 4C The diagram illustrates the following scenario: After UE 120 receives a priority indication associated with the second high priority physical uplink channel, UE 120 receives a multiplexing indication associated with the first high priority physical uplink channel.

[0074] In some aspects, the manner in which UE 120 performs multiplexing and / or prioritization depends on the order in which multiplexing indications and prioritization indications are received, as described below. In some aspects, it may be permissible to receive a multiplexing indication after receiving a prioritization indication. Alternatively, in some aspects, the UE may not expect to receive a multiplexing indication after receiving a prioritization indication. That is, in some aspects, receiving a multiplexing indication after receiving a prioritization indication may be an error condition. In some aspects, the UE may not expect to receive a priority indication after receiving a multiplexing indication. That is, after receiving a multiplexing indication associated with a first high-priority physical uplink channel overlapping with a low-priority physical uplink channel, the UE may not expect to receive a priority indication associated with another channel overlapping with both the low-priority and first high-priority physical uplink channels.

[0075] return Figure 4A As shown by reference numeral 420 in the attached figure, UE 120 can perform multiplexing and / or prioritization of low-priority physical uplink channels, first high-priority physical uplink channels, and second high-priority physical uplink channels. Next, as shown by reference numeral 425 in the attached figure, UE 120 transmits one or more physical uplink channels according to the prioritization or multiplexing performed by UE 120.

[0076] In some aspects, transmitting one or more physical uplink channels according to prioritization or multiplexing includes: discarding low-priority physical uplink channels; and multiplexing a first high-priority physical uplink channel and a second high-priority physical uplink channel.

[0077] For example, as described above, before UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 may receive the multiplexing indication associated with the first high-priority physical uplink channel. In such a case, after UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 may determine to discard the low-priority physical uplink channel. Regarding the first high-priority physical uplink channel, UE 120 may determine that the first and second high-priority physical uplink channels meet the multiplexing timeline (e.g., a timing threshold indicating whether the first and second high-priority physical uplink channels can be multiplexed). Therefore, UE 120 may multiplex the first and second high-priority physical uplink channels and may discard the low-priority physical uplink channel.

[0078] As another example, as described above, UE 120 may receive a multiplexing indication associated with the first high-priority physical uplink channel before receiving a prioritization indication associated with the second high-priority physical uplink channel. In this case, after UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 may determine to discard the low-priority physical uplink channel and to multiplex the first and second high-priority physical uplink channels. It is worth noting that in this example, UE 120 does not explicitly determine whether the multiplexing timeline is met. Therefore, UE 120 may multiplex the first and second high-priority physical uplink channels and may discard the low-priority physical uplink channel.

[0079] As another example, as described above, UE 120 may receive a multiplexing indication associated with a first high-priority physical uplink channel before receiving a prioritization indication associated with a second high-priority physical uplink channel. In such a case, after UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 may multiplex the first and second high-priority physical uplink channels and may determine that the resource set of channels resulting from the multiplexing of the first and second high-priority physical uplink channels at least partially overlaps with the resource set in which low-priority physical uplink channels are scheduled. Based at least in part on this determination, UE 120 may discard the low-priority physical uplink channels. Therefore, in this example, UE 120 first multiplexes physical uplink channels of the same priority, and when the resulting channel overlaps with a low-priority physical uplink channel, UE 120 discards the low-priority physical uplink channel.

[0080] As another example, as described above, UE 120 may receive a priority indication associated with a second high-priority physical uplink channel before receiving a multiplexing indication associated with a first high-priority physical uplink channel. In such a case, after UE 120 receives the multiplexing indication associated with the first high-priority physical uplink channel, UE 120 may multiplex only the high-priority physical uplink channel indicating priority (e.g., the second high-priority physical uplink channel) and the currently high-priority physical uplink channel indicating multiplexing (e.g., the first high-priority physical uplink channel). Alternatively, UE 120 may multiplex all high-priority physical uplink channels (e.g., the first and second high-priority physical uplink channels). In these examples, UE 120 may be configured to discard low-priority physical uplink channels at least partially based on the priority indication. Therefore, UE 120 may multiplex the first and second high-priority physical uplink channels and may discard low-priority physical uplink channels.

[0081] As another example, as described above, UE 120 may receive a priority indication associated with a second high-priority physical uplink channel before receiving a multiplexing indication associated with a first high-priority physical uplink channel. In such a case, after UE 120 receives the multiplexing indication associated with the first high-priority physical uplink channel, UE 120 may multiplex the first and second high-priority physical uplink channels and may determine that the resource set of channels resulting from the multiplexing of the first and second high-priority physical uplink channels at least partially overlaps with the resource set in which low-priority physical uplink channels are scheduled. Based at least in part on this determination, UE 120 may discard the low-priority physical uplink channels. Therefore, in this example, UE 120 first multiplexes physical uplink channels of the same priority, and when the resulting channel overlaps with a low-priority physical uplink channel, UE 120 discards the low-priority physical uplink channel.

[0082] In some aspects, transmitting one or more physical uplink channels according to prioritization or multiplexing includes: discarding low-priority physical uplink channels; discarding a first high-priority physical uplink channel; and transmitting a second high-priority physical uplink channel.

[0083] As another example, as described above, UE 120 may receive a multiplexing indication associated with a first high-priority physical uplink channel before receiving a prioritization indication associated with a second high-priority physical uplink channel. In such a case, after UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 can determine that the low-priority physical uplink channel and the high-priority physical uplink channel indicated for multiplexing (e.g., the low-priority physical uplink channel and the first high-priority physical uplink channel) will be discarded. The principle here is that the first high-priority physical uplink channel may be important, but not to the point that it cannot be multiplexed with a low-priority physical uplink channel. Therefore, when it conflicts with a high-priority physical uplink channel requiring priority (e.g., the second high-priority physical uplink channel), the first high-priority physical uplink channel can be discarded. It is worth noting that, in such a scenario, if the low-priority physical uplink channel is PUCCH and / or the first high-priority physical uplink channel is PUCCH, UE 120 can store content for use on another physical uplink channel scheduled after the second high-priority channel and indicate multiplexing. Therefore, UE 120 can transmit the second high-priority physical uplink channel and can discard both the first high-priority physical uplink channel and the low-priority physical uplink channel.

[0084] As another example, as described above, UE 120 may receive a multiplexing indication associated with the first high-priority physical uplink channel before receiving a prioritization indication associated with the second high-priority physical uplink channel. In such a case, after UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 may determine to discard the low-priority physical uplink channel. Regarding the first high-priority physical uplink channel, UE 120 may determine that the first and second high-priority physical uplink channels do not meet the multiplexing timeline (e.g., a timing threshold indicating whether the first and second high-priority physical uplink channels can be multiplexed). Therefore, UE 120 may send the second high-priority physical uplink channel and may discard the first high-priority physical uplink channel and the low-priority physical uplink channel.

[0085] In some aspects, transmitting one or more physical uplink channels according to prioritization or multiplexing includes: multiplexing a first high-priority physical uplink channel and a second high-priority physical uplink channel; and transmitting a low-priority physical uplink channel based at least in part on a determination that the resource set of the channel resulting from multiplexing the first high-priority physical uplink channel and the second high-priority physical uplink channel does not overlap with a second resource set.

[0086] For example, as described above, before UE 120 receives a prioritization indication associated with a second high-priority physical uplink channel, UE 120 may receive a multiplexing indication associated with a first high-priority physical uplink channel. In such a case, after UE 120 receives the prioritization indication associated with the second high-priority physical uplink channel, UE 120 may multiplex the first and second high-priority physical uplink channels and may determine that the resource set of channels resulting from the multiplexing of the first and second high-priority physical uplink channels does not at least partially overlap with the resource set in which low-priority physical uplink channels are scheduled. Based at least in part on this determination, UE 120 may transmit the low-priority physical uplink channel. Therefore, in this example, UE 120 first multiplexes physical uplink channels of the same priority, and when the resulting channel does not overlap with the low-priority physical uplink channel, UE 120 transmits the low-priority physical uplink channel.

[0087] As another example, as described above, UE 120 may receive a prioritization indication associated with a second high-priority physical uplink channel before receiving a multiplexing indication associated with a first high-priority physical uplink channel. In such a case, after UE 120 receives the multiplexing indication associated with the first high-priority physical uplink channel, UE 120 may multiplex the first and second high-priority physical uplink channels and may determine that the resource set of channels resulting from multiplexing the first and second high-priority physical uplink channels does not at least partially overlap with the resource set in which low-priority physical uplink channels are scheduled. Based at least in part on this determination, UE 120 may transmit the low-priority physical uplink channel. Therefore, in this example, UE 120 first multiplexes physical uplink channels of the same priority, and when the resulting channel does not overlap with the low-priority physical uplink channel, UE 120 transmits the low-priority physical uplink channel.

[0088] In some aspects, transmitting one or more physical uplink channels according to prioritization or multiplexing includes: multiplexing a first high-priority physical uplink channel, a second high-priority physical uplink channel, and a low-priority physical uplink channel.

[0089] For example, as described above, UE 120 may receive a prioritization indication associated with a second high-priority physical uplink channel before receiving a multiplexing indication associated with a first high-priority physical uplink channel. In such a case, UE 120 can be configured to perform multiplexing on all physical uplink channels in an overlapping physical uplink channel group. Therefore, in this example, UE 120 multiplexes the low-priority physical uplink channel, the first high-priority physical uplink channel, and the second high-priority physical uplink channel.

[0090] In some aspects, a single PUCCH group is configured for UE 120, and simultaneous PUCCH and PUSCH transmissions are not allowed. In such cases, UE 120 can implement any or more of the techniques described herein for multiplexing and / or prioritization.

[0091] In some aspects, a single PUCCH group is configured for UE 120, allowing simultaneous PUCCH and PUSCH transmission across multiple carriers. In some such cases, multiplexing or prioritization is performed only on the primary cell. For example, multiplexing across PUCCH and PUSCH, as well as multiplexing of PUCCH and PUCCH with different priorities, may only occur on the primary cell. Here, because parallel transmission across different carriers is allowed, prioritization is also limited to the primary cell. Therefore, handling both multiplexing and prioritization is limited to the primary cell and can be performed using any one or more techniques described herein. In some aspects, because simultaneous PUCCH and PUSCH transmission is allowed, UE 120 can transmit PUSCH on a secondary cell simultaneously with transmitting one or more physical uplink channels on the primary cell, depending on multiplexing or prioritization.

[0092] Alternatively, in some cases where a single PUCCH group is configured for UE 120 and simultaneous PUCCH and PUSCH transmissions are allowed across multiple carriers, prioritization or multiplexing across multiple carriers is permitted. For example, when a PUCCH is scheduled / configured for transmission on the primary cell and indicated for multiplexing, the PUCCH can be multiplexed with any overlapping PUSCH on any carrier. Here, as an example, UE 120 can select the PUSCH with which the PUCCH will be multiplexed as an overlapping PUSCH on a carrier with an index (e.g., the lowest index). Furthermore, UE 120 can select a PUSCH with the same priority as the PUCCH (e.g., UE 120 can select a carrier with an index of a scheduled PUSCH of the same priority). Here, if no overlapping PUSCH of the same priority exists on any of the multiple carriers, UE 120 can multiplex the PUCCH on a PUSCH on a carrier with an index. It is worth noting that in such cases, when PUCCH or PUSCH is scheduled on the primary cell and indicated for priority, only the physical uplink channel on the primary cell is affected (i.e., canceled). In some aspects, because simultaneous PUCCH and PUSCH transmission is allowed, UE 120 can transmit PUSCH on the secondary cell simultaneously with transmitting one or more physical uplink channels on the primary cell, depending on multiplexing or priority.

[0093] In some aspects, two PUCCH groups are configured for UE 120, allowing simultaneous PUCCH and PUSCH transmission across multiple carriers. In such cases, prioritization or multiplexing is performed (independently) for each PUCCH group. In some aspects, any one or more of the techniques described above can be used to perform prioritization or multiplexing for a given PUCCH group.

[0094] As pointed out above, Figures 4A-4C This is provided as an example. Other examples may differ from the one provided. Figures 4A-4C The example described.

[0095] Figure 5 This is a schematic diagram illustrating an example process 500 performed by a UE, for example, according to this disclosure. Example process 500 is an example in which a UE (e.g., UE 120) performs operations associated with dynamic multiplexing and prioritization for resolving conflicts in the physical uplink channel.

[0096] like Figure 5 As shown, in some aspects, process 500 may include: receiving a multiplexing indication, the multiplexing indication indicating that a first high-priority physical uplink channel scheduled in a first resource set is to be multiplexed with a low-priority physical uplink channel scheduled in a second resource set, the first resource set and the second resource set at least partially overlapping (block 510). For example, the UE (e.g., using antenna 252, demodulator 254, MIMO detector 256, receiver processor 258, controller / processor 280 and / or memory 282) may receive the multiplexing indication indicating that a first high-priority physical uplink channel scheduled in a first resource set is to be multiplexed with a low-priority physical uplink channel scheduled in a second resource set, the first resource set and the second resource set at least partially overlapping, as described above.
