Numerous other aspects are described.

Description

Technical Field

[0001] All aspects of this disclosure relate to wireless communication in general, and to techniques and apparatus for scheduling uplink transmissions across multiple frequency bands. Background Technology

[0002] 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 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 / LTE-Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. UEs may communicate with network nodes via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0004] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and 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; and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

[0041] Transmission handover enables User Equipment (UE) to transmit uplink transmissions on different frequency bands. For uplink transmission handover involving a single frequency band pair, the UE may transmit a first uplink transmission on a first frequency band, perform one or more transmission handover operations to switch to a second frequency band, and transmit a second uplink transmission on that second frequency band. Uplink transmission handover for a single frequency band pair may involve a minimum processing time for the UE to switch from the first frequency band to the second frequency band. For example, this minimum processing time may allow the UE time to prepare uplink data, prepare the transmission chain (e.g., tune from the first frequency band to the second frequency band), etc. Providing the UE with this minimum processing time to perform the transmission handover helps ensure that the UE transmits the second uplink transmission as scheduled.

[0042] For uplink transmission handover involving multiple frequency bands, there is no explicitly defined minimum processing time. For example, if a UE initially tunes to both the first and second frequency bands simultaneously, and the UE receives one or more uplink grants scheduled for uplink transmissions on the third and / or fourth frequency bands, the UE may not have sufficient time to switch to the third and / or fourth frequency bands in a timely manner to transmit one or more uplink transmissions. Therefore, the UE may be unable to transmit the uplink transmission as scheduled.

[0043] This document provides specific implementations for scheduling uplink transmissions across multiple frequency bands (e.g., overlapping or non-overlapping uplink transmissions). In some implementations, the uplink transmissions overlap in time (e.g., the uplink transmissions overlap at least partially in time). For example, a UE may establish a connection with a network node, and when the UE is configured to transmit on a first frequency band and a second frequency band, the UE may receive one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band. The first uplink transmission and the second uplink transmission may overlap in time. The UE may transmit no later than an offset (e.g., T) from the earliest start time of the first uplink transmission and the second uplink transmission. proc,2 The uplink permission is received at the time specified in the parameter value. This offset may be based at least in part on the third and fourth frequency bands.

[0044] In some specific implementations, the uplink transmissions do not overlap in time. For example, the UE may establish a connection with a network node, and when the UE is configured to transmit on a first frequency band and a second frequency band, the UE may receive one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band. The first uplink transmission and the second uplink transmission do not overlap in time. The one or more uplink grants may schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission.

[0045] Scheduling the uplink transmission according to the specific implementation described herein helps ensure that at least a minimum processing time is provided to the UE to perform uplink transmission handover involving multiple frequency bands. In the case where the uplink transmissions overlap in time, receiving the one or more uplink grants at a time no later than the offset from the earliest start time of the first uplink transmission and the second uplink transmission helps ensure that the UE has sufficient time to perform the transmission handover. In the case where the uplink transmissions do not overlap in time, scheduling the second uplink transmission based at least in part on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission helps ensure that the UE has sufficient time to perform the transmission handover. In either case, the UE can perform the transmission handover and therefore can transmit the first uplink transmission and / or the second uplink transmission as scheduled.

[0046] Various aspects of this disclosure are 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 so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using structures, functionalities, or structures and functionalities other than or different from the various aspects of the disclosure herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0047] Several aspects of a telecommunications system will now be presented 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 system as a whole.

[0048] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0049] Figure 1 This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0050] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or to one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0051] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0052] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, "base station" or "network node" may refer to a CU, DU, RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device can include more than one base station.

[0053] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions to other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, repeater, etc.

[0054] The wireless network 100 can be a heterogeneous network, comprising different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference in the wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0055] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0056] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric 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), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0057] Some UEs 120 may be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as 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, electronically coupled, and / or electrically coupled.

[0058] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0059] 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 network node 110 as an intermediary device to communicate 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, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0060] Devices in 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 Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. A similar naming issue sometimes occurs with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz-300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0061] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have designated the operating bands for these IF bands as the frequency range designation FR3 (7.125GHz–24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to IF band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6GHz. For example, three higher operating bands have been designated as the frequency range designations 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.

[0062] 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 below 6 GHz, within FR1, or including 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 can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0063] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may establish a connection with a network node; and when the UE is configured to transmit on a first frequency band and a second frequency band, receive one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission overlap in time, and wherein the one or more uplink grants are received at a time no later than an offset from the earliest start time of the first uplink transmission and the second uplink transmission, wherein the offset is at least partially based on the third frequency band and the fourth frequency band.

[0064] In some aspects, the communication manager 140 may establish a connection with a network node; and when the UE is configured to transmit on a first frequency band and a second frequency band, receive one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission do not overlap in time, and wherein the one or more uplink grants schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0065] In some aspects, network node 110 may include communication manager 150. As described in more detail elsewhere herein, communication manager 150 may establish a connection with the UE; and when the UE is configured to transmit on a first frequency band and a second frequency band, output one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission overlap in time, and wherein the one or more uplink grants are received by the UE at a time no later than an offset from the earliest start time of the first uplink transmission and the second uplink transmission, wherein the offset is at least partially based on the third frequency band and the fourth frequency band.

[0066] In some aspects, the communication manager 150 may establish a connection with the UE; and when the UE is configured to transmit on a first frequency band and a second frequency band, output one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission do not overlap in time, and wherein the one or more uplink grants schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0067] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The examples described are different.

[0068] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to the present disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and modems 232. In some examples, network node 110 may include an interface, communication components, or another component facilitating communication with UE 120 or another network node. Some network nodes 110 may not include radio frequency components facilitating direct communication with UE 120, such as one or more CUs or one or more DUs.

[0069] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Allocation Information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., Cell-Specific Reference Signal (CRS) or Demodulation Reference Signal (DMRS)) and synchronization signals (e.g., Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can 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). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding 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 the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) 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 antennas 234a to 234t).

[0070] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 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 the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data for 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 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 UE 120 may be included in housing 284.

[0071] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0072] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, a set or more sets of antenna elements and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, a set or more sets of antenna elements and / or one or more antenna arrays, etc. Antenna panels, antenna groups, a set of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements and / or be coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components in the process).

[0073] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The 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 transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 5 to 16 ( ) aspects of any of the methods described in the method.

[0074] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 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 transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figures 5 to 16 ( ) aspects of any of the methods described in the method.

[0075] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component may perform one or more techniques associated with scheduling uplink transmissions on multiple frequency bands, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 9 The process 900 Figure 10 Process 1000 Figure 11 Process 1100 Figure 12 The operation of process 1200 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, transformation, and / or interpretation), these one or more instructions may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example... Figure 9 The process 900 Figure 10 Process 1000 Figure 11 Process 1100 Figure 12 The operation of process 1200 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.

[0076] In some aspects, UE 120 may include components for establishing a connection with a network node; and / or components for receiving one or more uplink grants when the UE is configured to transmit on a first frequency band and a second frequency band, the one or more uplink grants scheduling a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission overlap in time, and wherein the one or more uplink grants are received at a time no later than an offset from the earliest start time of the first uplink transmission and the second uplink transmission, wherein the offset is at least partially based on the third frequency band and the fourth frequency band. Components for UE 120 to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0077] In some aspects, UE 120 may include components for establishing a connection with a network node; and / or components for receiving one or more uplink grants when the UE is configured to transmit on a first frequency band and a second frequency band, the one or more uplink grants scheduling a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission do not overlap in time, and wherein the one or more uplink grants schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission. Components for UE 120 to perform the operations described herein may include, for example, one or more of a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0078] In some aspects, network node 110 includes components for establishing a connection with the UE; and / or components for outputting one or more uplink grants when the UE is configured to transmit on a first frequency band and a second frequency band, the one or more uplink grants scheduling a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission overlap in time, and wherein the one or more uplink grants are received by the UE at a time no later than an offset from the earliest start time of the first uplink transmission and the second uplink transmission, wherein the offset is at least partially based on the third frequency band and the fourth frequency band. Components for network node 110 to perform the operations described herein may include, for example, one or more of a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0079] In some aspects, network node 110 includes components for establishing a connection with the UE; and / or components for outputting one or more uplink grants when the UE is configured to transmit on a first frequency band and a second frequency band, the one or more uplink grants scheduling a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission do not overlap in time, and wherein the one or more uplink grants schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission.

[0080] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above for these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0081] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The examples described are different.

[0082] The deployment of communication systems such as 5G NR systems can be arranged in a variety of ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in aggregated or decomposed architectures. For example, base stations (such as Node B (NB), evolved NB (eNB), NR base stations, 5G NB, access points (APs), TRPs, or cells, etc.) or one or more units (or components) performing base station functions can be implemented as aggregated base stations (also known as standalone base stations or monolithic base stations) or decomposed base stations. A "network entity" or "network node" can refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or combinations thereof).

[0083] Aggregated base stations (e.g., aggregated network nodes) can be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU can also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0084] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed individually. Decomposed base stations can include functionality implemented by two or more units across various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. Each unit of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0085] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0086] Each unit in the clusters (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cluster, or an associated processor or controller providing instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more units in other clusters via transmission media. In some examples, each unit in the cluster may include a wired interface and a wireless interface configured to receive signals via a wired transmission media or transmit signals to one or more units in other clusters, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals via a wireless transmission media or transmit signals to one or more units in other clusters, or both.

[0087] In some aspects, the CU 310 can host one or more higher-level control functions. Such control functions may include Radio Resource Control (RRC) functions, Packet Data Convergence Protocol (PDCP) functions, or Service Data Adaptation Protocol (SDAP) functions, etc. Each control function can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can be logically divided into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP units can communicate bidirectionally with the CU-CP units via an interface (such as an E1 interface). The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0088] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented by one or more modules for Fast Fourier Transform (FFT), Inverse FFT (iFFT), Digital Beamforming, or Physical Random Access Channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0089] Each RU 340 can implement lower-layer functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as lower-layer function splitting). In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as vRAN architecture).

[0090] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTTRIC 325. In some implementations, the SMO framework 305 may communicate with the hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0091] The non-RT RIC 315 can be configured to include logical functions enabling non-real-time control and optimization of RAN elements and resources, including AI / ML workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logical functions enabling near real-time control and optimization of RAN elements and resources via data collection and actions through an interface (e.g., via an E2 interface) that connects one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0092] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0093] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The examples described are different.

[0094] Transmission handover enables the UE to transmit uplink transmissions on different frequency bands. This uplink transmission can be carried by the Physical Uplink Shared Channel (PUSCH) and can be scheduled by uplink grant as downlink control information (DCI) carried in the Physical Downlink Control Channel (PDCCH). For uplink transmission handovers involving a single pair of frequency bands, the UE can transmit a first uplink transmission on the first frequency band, perform one or more transmission handover operations to switch to the second frequency band, and transmit a second uplink transmission on the second frequency band.

[0095] Uplink transmission handover for a single frequency band may involve a minimum processing time for the UE to switch from the first frequency band to the second frequency band. For example, this minimum processing time may allow the UE time to prepare uplink data, prepare the transmission chain (e.g., tune from the first frequency band to the second frequency band), etc. Providing the UE with this minimum processing time to perform the transmission handover helps ensure that the UE transmits the second uplink transmission as scheduled.

[0096] Figure 4 Example table 400 illustrates the values ​​of the PUSCH preparation time parameter N2 according to this disclosure. In some examples, the minimum processing time may depend on N2. For example... Figure 4 As shown, the value of N2 depends on the value of parameter μ in the parameter set. μ corresponds to μ DL or μ UL One of the factors that causes the maximum processing time. μ DL The subcarrier spacing of the downlink channel corresponding to the PDCCH used to transmit the DCI carrying the scheduling PUSCH, and μ ULThis corresponds to the subcarrier spacing of the uplink channel to be used to transmit PUSCH.

[0097] For example, N2 can be mapped to 10 symbols when μ = 0 and to 12 symbols when μ = 1. For instance, if the DCI carrier (e.g., a component carrier) corresponds to a subcarrier spacing of 15 kHz (μ = 0) and the uplink grant carrier (e.g., a component carrier) corresponds to a subcarrier spacing of 30 kHz (μ = 1), then N2 = 12 symbols. In this example, the UE can receive uplink grant within at least (e.g., calculated based on N2 = 12 symbols) a minimum processing time before the scheduled uplink transmission.

[0098] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The examples described are different.

[0099] For uplink transmission handover involving multiple frequency bands, there is no explicitly defined minimum processing time for the handover. Therefore, if the UE initially tunes to both the first and second frequency bands simultaneously, and the UE receives one or more uplink grants that schedule uplink transmissions on the third and / or fourth frequency bands, the UE may not have sufficient time to switch to the third and / or fourth frequency band in a timely manner to transmit one or more uplink transmissions. Consequently, the UE may be unable to transmit the uplink transmission as scheduled.

[0100] This document provides specific implementations for scheduling uplink transmissions across multiple frequency bands (e.g., overlapping or non-overlapping uplink transmissions). In some specific implementations, see references... Figure 5 and Figure 6 The uplink transmissions discussed overlap in time (e.g., the uplink transmissions overlap at least partially in time). In some specific implementations, such as those mentioned in the references... Figure 7 and Figure 8 The uplink transmissions discussed do not overlap in time.

[0101] Figure 5 This is a diagram illustrating example 500 of scheduling time-overlapping uplink transmissions across multiple frequency bands according to this disclosure. (See diagram 500 for example 500.) Figure 5 As shown, network node 110 and UE 120 can communicate with each other.

[0102] As shown by reference numeral 505, network node 110 and UE 120 can establish a connection (e.g., an RRC connection). As shown by reference numeral 510, UE 120 can be configured to transmit on a first frequency band and a second frequency band. For example, UE 120 can be configured to transmit corresponding uplink transmissions on the first frequency band and the second frequency band. For example, UE 120 can be configured to transmit the uplink transmissions on the first frequency band and the second frequency band simultaneously or with at least partial overlap in the time domain.

[0103] As shown by reference numeral 515 in the attached figure, when UE 120 is configured to transmit on the first and second frequency bands, network node 110 can output, and UE 120 can receive, one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band. The first and second uplink transmissions overlap in time. The one or more uplink grants are received at a time no later than an offset from the earliest start time of the first and second uplink transmissions. This offset is at least partially based on the third and fourth frequency bands.

[0104] Scheduling the uplink transmission according to the specific implementation described herein helps ensure that at least a minimum processing time is provided to the UE 120 to perform a transmission handover involving multiple frequency bands. For example, based on this offset (e.g., minimum processing time), the UE 120 can successfully perform a transmission handover even if the uplink transmissions overlap in time. In another example, based on the one or more uplink grants, the UE can transmit the first uplink transmission on the third frequency band and the second uplink transmission on the fourth frequency band.

[0105] In some examples, the offset can be T proc,2 The value of the parameter. This T proc,2 The parameter defines the minimum processing time involved in performing a transmit switch (e.g., the processing time from the last symbol of the PDCCH to the corresponding PUSCH carrying that uplink transmit). In some examples, T proc,2 =max((N2+d 2,1 +d2)(2048+144)·κ2 -μ ·T C +T ext +T switch ,d 2,2 ), where N2 is the PUSCH preparation time, T switch This indicates the duration of the frequency band switching interval, and d 2,1 d2, κ, T C T ext and d2,2 It is a constant. For example, if the uplink is allowed a time T before the uplink transmission is scheduled. proc,2 Upon arrival, UE 120 will have sufficient time to successfully perform the transmission handover.

[0106] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The examples described are different.

[0107] For uplink transmission handover involving multiple frequency bands, N2 and T may not be explicitly defined. switch Parameters. N2 and T can be defined. switch Parameters to avoid T proc,2 The parameter value is too small, causing the UE to be unable to perform uplink transmission handover. For example, insufficient T... proc,2 The parameter value may originate from the following scheme, in which the N2 parameter is defined as (μ DL μ UL The largest of ) where μ DL It is any μ corresponding to the corresponding downlink frequency band configured to carry DCI (e.g., uplink grant). DL The smallest of them, and μ UL It is any μ corresponding to the corresponding uplink frequency band configured to carry uplink transmissions authorized for scheduling by the one or more uplinks. UL The smallest of them.

[0108] For example, if UE 120 is configured to switch from a first frequency band (15 kHz subcarrier spacing (μ=0)) configured to carry DCI and uplink transmission to a first frequency band (30 kHz subcarrier spacing (μ=1)) configured to carry at least uplink transmission, and from a second frequency band (30 kHz subcarrier spacing (μ=1)) configured to carry DCI and uplink transmission to a second frequency band (15 kHz subcarrier spacing (μ=0)) configured to carry at least uplink transmission, then for uplink transmission handover involving multiple frequency band pairs, N2 = 10 symbols. However, for uplink transmission handover involving a single frequency band pair (e.g., if both frequency band pairs are considered independent), then for two frequency band pairs, N2 = 12 symbols. Therefore, T proc,2 The parameter value may actually lose two symbols, and therefore may not be sufficient for the UE to perform an uplink transmission handover before uplink transmission is scheduled. Therefore, this paper provides the N2 parameter and T switch The parameter configuration makes the generated T proc,2The parameter values ​​provide UE 120 with sufficient time to perform uplink transmission handover. In some examples, for the T values ​​provided above... proc,2 The μ in the formula for the parameter can correspond to μ UL =min{μ DL ,μ UL}

[0109] Figure 6 This is a diagram illustrating an example timeline 600 for scheduling time-overlapping uplink transmissions on multiple frequency bands according to this disclosure. As shown, initially, the UE is configured to transmit uplink transmissions on frequency bands A and B via corresponding transmission chains (“1Tx”). Upon receiving one or more uplink grants for scheduling uplink transmissions on frequency bands C and D, the UE may initiate one or more uplink transmission handover operations, enabling the UE to transmit uplink transmissions on frequency bands C and D via the corresponding transmission chains. These handover operations may occur simultaneously or may not occur simultaneously (e.g., a handover from frequency band A to frequency band C may occur simultaneously with a handover from frequency band B to frequency band D, or may not occur simultaneously with a handover from frequency band B to frequency band D). As shown, frequency bands C and D each have a timeline with T... switch The parameters correspond to the duration of the handover gap (“gap”). The uplink transmission scheduled on band C has a start time T0, and the uplink transmission scheduled on band D has a start time T0′. As shown, T0 occurs before T0′ (e.g., T0 is the earliest start time for both the uplink transmission on band C and the uplink transmission on band D).

[0110] The UE can be used during T0-T offset The uplink permission was received at or before T. offset It is T proc,2 If the UE is in T0-T offset Upon receiving uplink permission, the UE may not have sufficient time to perform uplink transmission handover before the earliest start time of uplink transmission in band C and band D (here, the start time of uplink transmission in band C). Based on this uplink permission, the UE can determine how to perform uplink transmission handover (e.g., when and in what order to switch bands).

[0111] refer to Figure 6At least two examples are described. In a first example, the one or more uplink permissions instruct the UE to switch from band A to band C and from band B to band D. For example, the one or more uplink permissions may explicitly identify band A as the source band and band C as the target band corresponding to band A, and may also explicitly identify band B as the source band and band D as the target band corresponding to band B. In a second example, the one or more uplink permissions instruct the UE to switch from bands A and B to bands C and band D. For example, the one or more uplink permissions may not explicitly identify the source-target band pair.

[0112] In the first example, the UE can be triggered to perform a transmission handover between two frequency band pairs (e.g., frequency band A to frequency band C, and frequency band B to frequency band D). Frequency band A and frequency band C may have different subcarrier spacings (e.g., frequency band A may have a subcarrier spacing of 15 kHz, and frequency band C may have a subcarrier spacing of 30 kHz), and frequency band B and frequency band D may have different subcarrier spacings (e.g., frequency band B may have a subcarrier spacing of 30 kHz, and frequency band D may have a subcarrier spacing of 15 kHz).

[0113] In some examples, T offset The parameter value may be based at least in part on the first N2 parameter value (e.g., N) associated with the first handover from frequency band A to frequency band C. 2,1 The values ​​of the parameters) and the second N2 parameter values ​​(e.g., N) associated with the second handover from band B to band D. 2,2 The maximum value among the parameter values. For example, T offset The parameter value can be N 2,1 Parameter values ​​and N 2,2 The maximum value among the parameter values.

[0114] N 2,1 The parameter can be the PUSCH preparation time parameter used for the first switch, and N 2,2 The parameter can be the PUSCH preparation time parameter used for the second switch. For example, N 2,1 Parameter values ​​and N 2,2 The maximum value among the parameter values ​​can be used as the reference for T provided above. proc,2 Input the N2 parameter value in the formula for the parameters. Make T offset The parameter values ​​are at least partially based on N. 2,1 Parameters and N 2,2 The maximum value in the parameters can help ensure T offset The parameter value is large enough so that the UE has enough time to perform uplink transmission handover before the uplink transmission is scheduled.

[0115] N 2,1The parameter value can be based at least in part on μ associated with frequency band A. DL1 Parameter values ​​and μ associated with frequency band C UL1 The larger of the parameter values. For example, N 2,1 The parameter value can be μ DL1 Parameter values ​​and μ UL1 The larger of the parameter values. N 2,2 The parameter value can be based at least in part on μ associated with frequency band B. DL2 Parameter values ​​and μ associated with frequency band D UL2 The larger of the parameter values. For example, N 2,2 The parameter value can be μ DL2 Parameter values ​​and μ UL2 The larger of the parameter values.

[0116] For example, μ associated with frequency band A (15kHz) DL1 The parameter value can be 0; μ is associated with the frequency band C (30kHz). UL1 The parameter value can be 1; μ is associated with frequency band B (30kHz). DL2 The parameter value can be 1; and μ is associated with the frequency band D (15kHz). UL2 The parameter value can be 0. Therefore, N 2,1 Parameter values ​​and N 2,2 The parameter value can be equal to 12 (compared to, for example, 10).

[0117] Make N 2,1 The parameter values ​​are at least partially based on μ associated with frequency band A. DL1 Parameter values ​​and μ associated with frequency band C UL1 The larger of the parameter values, and makes N 2,2 The parameter values ​​are at least partially based on μ associated with frequency band B. DL2 Parameter values ​​and μ associated with frequency band D UL2 The larger of the parameter values ​​can also help ensure T offset It is large enough so that the UE has enough time to perform uplink transmission handover before the uplink transmission is scheduled.

[0118] In some examples, T offset The parameter values ​​can be at least partially based on T. switch A parameter value, which is based at least in part on the larger of a first handover period associated with a first handover (from band A to band C) and a second handover period associated with a second handover (from band B to band D). For example, T switch The parameter value can be the larger of the first handover period and the second handover period. The first handover period and the second handover period can be reported by the UE to the network node.

[0119] Make T switch Using parameter values ​​that are at least partially based on the largest of the first and second switching cycles can help ensure T offset The parameter value is large enough that the UE has sufficient time to perform an uplink transmission handover before the uplink transmission is scheduled. For example, in the case of the UE directly switching from band A to band C and from band B to band D internally, T... switch The parameter value, based at least in part on the maximum of the first and second switching cycles, ensures T offset The parameter value is greater than the time involved in the internal UE operation used for uplink transmission handover.

[0120] In some examples, T offset The parameter values ​​can be at least partially based on T. switch A parameter value, which is based at least in part on the largest of the following: a first handover period associated with a first handover from band A to band C; a second handover period associated with a second handover from band B to band C; a third handover period associated with a third handover from band A to band D; and a fourth handover period associated with a fourth handover from band B to band D. For example, T switch The parameter value can be the largest of the first handover period, the second handover period, the third handover period, and the fourth handover period. The first handover period, the second handover period, the third handover period, and the fourth handover period can be reported by the UE to the network node.

[0121] Make T switch Using parameter values ​​that are at least partially based on the largest of the first, second, third, and fourth switching cycles can help ensure T offset The parameter value is large enough that the UE has sufficient time to perform an uplink transmission handover before the uplink transmission is scheduled. For example, if the UE does not indicate to the network node which transmission chain to which target frequency band (e.g., whether the UE is switching from frequency band A to frequency band C and from frequency band B to frequency band D, or from frequency band B to frequency band C and from frequency band A to frequency band D), then T... switch The parameter value, based at least in part on the maximum of the first, second, third, and fourth switching cycles, ensures T. offset The parameter value is greater than the internal UE operation involved in the uplink transmission handover.

[0122] In some examples, T offset The parameter values ​​can be at least partially based on T. switchA parameter value, which is based at least in part on the sum of: the first maximum of a first handover period associated with a first handover from band A to band C and a second handover period associated with a second handover from band B to band C; and the second maximum of a third handover period associated with a third handover from band A to band D and a fourth handover period associated with a fourth handover from band B to band D. For example, T switch The parameter value can be the sum of the first and second largest values. The first, second, third, and fourth handover cycles can be reported by the UE to the network node.

[0123] Make T switch Parameter values ​​based at least in part on the sum of the first and second largest can help ensure T offset The parameter value is large enough that the UE has sufficient time to perform an uplink transmission handover before the uplink transmission is scheduled. For example, if the UE does not indicate to the network node which transmission chain to which target frequency band to switch to, and the UE switches from one frequency band to another via one or more intermediate frequency bands (e.g., the UE switches from frequency band A to frequency band C and then to frequency band D), then T... switch The parameter values, at least in part, based on the sum of the first and second maximums, ensure that T offset The parameter value is greater than the internal UE operation involved in the uplink transmission handover.

[0124] In some examples, T switch Parameter values ​​can also be based, at least in part, on another sum. This other sum can be the sum of that sum (e.g., the sum of the first and second largest) and a predefined value. For example, T switch The parameter value can be the sum of this total and another predefined value. This predefined value can be a value reported by the UE to the network node, or a value fixed in a standard specification. This predefined value can also help ensure T offset The parameter value is greater than the internal UE operation involved in the uplink transmission handover.

[0125] In some examples, T offset The parameter values ​​can be at least partially based on T. switch A parameter value, which is based at least in part on the sum of the following: a first handover period associated with a first handover from band A to band C; a second handover period associated with a second handover from band A to band D; a third handover period associated with a third handover from band B to band C; and a fourth handover period associated with a fourth handover from band B to band D. For example, T switchThe parameter value can be the sum of the first handover cycle, the second handover cycle, the third handover cycle, and the fourth handover cycle. The first handover cycle, the second handover cycle, the third handover cycle, and the fourth handover cycle can be reported by the UE to the network node.

[0126] In some examples, T switch The parameter value may also be based, at least in part, on the sum of the sum (e.g., the sum of the first handover cycle, the second handover cycle, the third handover cycle, and the fourth handover cycle) and another sum of a predefined value. For example, the predefined value may be a value reported by the UE to the network node, or a value fixed in a standard specification.

[0127] In the second example, the one or more uplink permissions instruct the UE to switch from bands A and B to bands C and D. For example, a network node can configure the UE without explicitly identifying the source-target band pair, such that the UE is configured to transmit on bands A and B before the handover and on bands C and D after the handover. Bands A and B may have different subcarrier spacings (e.g., band A may have a 15 kHz subcarrier spacing and band B may have a 30 kHz subcarrier spacing), and bands C and D may have different subcarrier spacings (e.g., band C may have a 30 kHz subcarrier spacing and band D may have a 15 kHz subcarrier spacing).

[0128] In some examples, frequency bands A and B can be configured to carry downlink transmissions (e.g., including one or more uplink-permitted DCIs). offset The parameter values ​​may be at least partially based on the N² parameter values. The N² parameter values ​​may be at least partially based on μ. DL Parameter values ​​and μ UL The larger of the parameter values.

[0129] μ DL The parameter value can be associated with frequency band A and frequency band B, and μ UL The parameter value can be associated with frequency band C and frequency band D. In some examples, μ DL The parameter value can be based at least in part on μ associated with frequency band A. DL1 Parameter values ​​(e.g., μ) DL1 =0) and μ associated with frequency band B DL2 Parameter values ​​(e.g., μ) DL2 The largest of (=1), and μ UL The parameter value can be at least partially based on μ associated with the frequency band C. UL1 Parameter values ​​(e.g., μ) UL1 =1) and μ associated with frequency band D UL2 Parameter values ​​(e.g., μ) UL2The largest of (=0). For example, μ DL The parameter value can be μ DL1 Parameter values ​​and μ DL2 The largest of the parameter values, and μ UL The parameter value can be μ UL1 Parameter values ​​and μ UL2 The smallest of the parameter values.

[0130] In some examples, μ DL The parameter value can be at least partially based on μ. DL1 Parameter values ​​and μ DL2 The largest of the parameter values, and μ UL The parameter value can be at least partially based on μ. UL1 Parameter values ​​and μ UL2 The smallest of the parameter values. For example, μ DL The parameter value can be μ DL1 Parameter values ​​and μ DL2 The largest of the parameter values, and μ UL The parameter value can be μ UL1 Parameter values ​​and μ UL2 The smallest of the parameter values.

[0131] In some examples, μ DL The parameter value can be at least partially based on μ. DL1 Parameter values ​​and μ DL2 The smallest of the parameter values, and μ UL The parameter value can be at least partially based on μ. UL1 Parameter values ​​and μ UL2 The smallest of the parameter values. For example, μ DL The parameter value can be μ DL1 Parameter values ​​and μ DL2 The smallest of the parameter values, and μ UL The parameter value can be μ UL1 Parameter values ​​and μ UL2 The smallest of the parameter values.

[0132] In some examples, μ DL The parameter value can be at least partially based on μ. DL1 Parameter values ​​and μ DL2 The largest of the parameter values, and μ UL The parameter value can be at least partially based on μ. UL1 Parameter values ​​and μ UL2 The smallest of the parameter values. For example, μ DL The parameter value can be μ DL1 Parameter values ​​and μ DL2 The largest of the parameter values, and μ UL The parameter value can be μ UL1 Parameter values ​​and μUL2 The smallest of the parameter values.

[0133] In some examples, T offset The parameter values ​​can be at least partially based on T. switch A parameter value, which is based at least in part on the largest of the following: a first handover period associated with a first handover from band A to band C; a second handover period associated with a second handover from band B to band C; a third handover period associated with a third handover from band A to band D; and a fourth handover period associated with a fourth handover from band B to band D. For example, T switch The parameter value can be the largest of the first handover period, the second handover period, the third handover period, and the fourth handover period. The first handover period, the second handover period, the third handover period, and the fourth handover period can be reported by the UE to the network node.

[0134] Make T switch Using parameter values ​​that are at least partially based on the largest of the first, second, third, and fourth switching cycles can help ensure T offset The parameter value is large enough that the UE has sufficient time to perform an uplink transmission handover before the uplink transmission is scheduled. For example, if the UE does not indicate to the network node which transmission chain to which target frequency band (e.g., whether the UE is switching from frequency band A to frequency band C and from frequency band B to frequency band D, or from frequency band B to frequency band C and from frequency band A to frequency band D), then T... switch The parameter value, based at least in part on the maximum of the first, second, third, and fourth switching cycles, ensures T. offset The parameter value is greater than the internal UE operation involved in the uplink transmission handover.

[0135] In some examples, T offset The parameter values ​​can be at least partially based on T. switch A parameter value, which is based at least in part on the sum of: the first maximum of a first handover period associated with a first handover from band A to band C and a second handover period associated with a second handover from band B to band C; and the second maximum of a third handover period associated with a third handover from band A to band D and a fourth handover period associated with a fourth handover from band B to band D. For example, T switch The parameter value can be the sum of the first and second largest values. The first, second, third, and fourth handover cycles can be reported by the UE to the network node.

[0136] Make T switchParameter values ​​based at least in part on the sum of the first and second largest can help ensure T offset The parameter value is large enough that the UE has sufficient time to perform an uplink transmission handover before the uplink transmission is scheduled. For example, if the UE does not indicate to the network node which transmission chain to which target frequency band to switch to, and the UE switches from one frequency band to another via one or more intermediate frequency bands (e.g., the UE switches from frequency band A to frequency band C and then to frequency band D), then T... switch The parameter values, at least in part, based on the sum of the first and second maximums, ensure that T offset The parameter value is greater than the internal UE operation involved in the uplink transmission handover.

[0137] In some examples, T switch Parameter values ​​can also be based, at least in part, on another sum of this sum (e.g., the sum of the first and second largest) and a predefined value. For example, T switch The parameter value can be the sum of this total and another predefined value. This predefined value can be a value reported by the UE to the network node, or a value fixed in a standard specification. This predefined value can also help ensure T offset The parameter value is greater than the internal UE operation involved in the uplink transmission handover.

[0138] In some examples, T offset The parameter values ​​can be at least partially based on T. switch A parameter value, which is based at least in part on the sum of the following: a first handover period associated with a first handover from band A to band C; a second handover period associated with a second handover from band A to band D; a third handover period associated with a third handover from band B to band C; and a fourth handover period associated with a fourth handover from band B to band D. For example, T switch The parameter value can be the sum of the first handover cycle, the second handover cycle, the third handover cycle, and the fourth handover cycle. The first handover cycle, the second handover cycle, the third handover cycle, and the fourth handover cycle can be reported by the UE to the network node.

[0139] In some examples, T switch The parameter value may also be based, at least in part, on the sum of the sum (e.g., the sum of the first handover cycle, the second handover cycle, the third handover cycle, and the fourth handover cycle) and another sum of a predefined value. For example, the predefined value may be a value reported by the UE to the network node, or a value fixed in a standard specification.

[0140] Whether a UE can switch to another frequency band (e.g., switch to band D) while transmitting in one frequency band (e.g., band C) depends on whether the UE is a baseline UE or a UE with band-invariant capability. A baseline UE may not be able to switch to another frequency band while transmitting in one, and configuring the baseline UE to perform this operation could lead to an error, or cause a transmission interruption on another frequency when the baseline UE switches to that band (e.g., the UE could stop transmitting in band C, switch to band D, and subsequently resume transmission in band C). A UE with band-invariant capability can be able to switch to another frequency band while transmitting in one. For example, a UE with band-invariant capability can allow transmission in band C to remain unchanged for switching band pairs (e.g., from band A to band D and / or from band B to band D). For example, a UE with band-invariant capability may include a first transmission chain that remains tuned to band C during switching, and a second transmission chain that switches to band D while the first transmission chain is transmitting in band C.

[0141] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The examples described are different.

[0142] Figure 7 This is a diagram illustrating example 700 of scheduling uplink transmissions on multiple frequency bands that do not overlap in time, according to this disclosure. (See diagram for example 700.) Figure 7 As shown, network node 110 and UE 120 can communicate with each other.

[0143] As shown by reference numeral 705, network node 110 and UE 120 can establish a connection (e.g., an RRC connection). As shown by reference numeral 710, UE 120 can be configured to transmit on a first frequency band and a second frequency band. For example, UE 120 can be configured to transmit corresponding uplink transmissions on the first frequency band and the second frequency band. For example, UE 120 can be configured to transmit the uplink transmissions simultaneously or with at least partial overlap in the time domain on the first frequency band and the second frequency band.

[0144] As shown by reference numeral 715 in the attached figure, when UE 120 is configured to transmit on the first frequency band and the second frequency band, network node 110 can output, and UE 120 can receive, one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band. The first uplink transmission and the second uplink transmission do not overlap in time. The one or more uplink grants schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission.

[0145] Scheduling the uplink transmission according to the specific implementation described herein helps ensure that at least a minimum processing time is provided to the UE 120 to perform a transmission handover involving multiple frequency bands. For example, scheduling the second uplink transmission based at least in part on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission helps ensure that the UE has sufficient time to perform the transmission handover. In another example, depending on the one or more uplink grants, the UE may transmit the first uplink transmission on the third frequency band and the second uplink transmission on the fourth frequency band.

[0146] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The examples described are different.

[0147] Figure 8 This is a diagram illustrating example timelines (e.g., timelines 800 and 810) for scheduling uplink transmissions on multiple frequency bands that do not overlap in time, according to this disclosure. In timelines 800 and 810, initially, the UE is configured to transmit uplink transmissions on frequency bands A and B via corresponding transmission chains (“1Tx”). Upon receiving one or more uplink grants for scheduling uplink transmissions on frequency bands C and D, the UE may initiate one or more uplink transmission handover operations, which enables the UE to transmit uplink transmissions on frequency bands C and D via the corresponding transmission chains. As shown, frequency bands C and D each have a timeline with Tx. switch The parameters correspond to the duration of the handover gap (“gap”). The uplink transmission scheduled on band C has a start time T0, and the uplink transmission scheduled on band D has a start time T0′. As shown, T0 occurs before T0′ (e.g., T0 is the earliest start time for both the uplink transmission on band C and the uplink transmission on band D).

[0148] The UE can be used during T0-T offset Uplink permission is granted at or before the location where the uplink transmission on the scheduled frequency band C is received. For example, T offset It can be T proc,2 T offset The value can be based at least in part on frequency band A or frequency band B, and at least in part on frequency band C (e.g., T). offset The value can be based on the N2 parameter value and / or T. switch Parameter values, where N2 parameter values ​​and / or T switch The parameter values ​​can be determined based on attributes associated with frequency band A or frequency band B and frequency band C (e.g., one or more μ parameters). If the UE is in T0-T offsetIf uplink permission is subsequently received, the UE may not have sufficient time to perform an uplink transmission handover before the start time of uplink transmission on frequency band C. Therefore, during T0-T... offset Receiving uplink permission for uplink transmission on band C at or before the scheduled uplink transmission can help ensure that the UE has sufficient time to perform a transmission handover to band C before transmission on band C.

[0149] The UE can be used during T0′-T offset Uplink permission is granted at or before the location where the uplink transmission on the scheduled frequency band D is received. For example, T offset It can be T proc,2 T offset The value can be based at least in part on frequency band A or frequency band B, and at least in part on frequency band D (e.g., T). offset The value can be based on the N2 parameter value and / or T. switch Parameter values, where N2 parameter values ​​and / or T switch The parameter values ​​can be determined based on attributes associated with frequency band A or frequency band B and frequency band D (e.g., one or more μ parameters). If the UE is in T0′-T offset If the uplink permission is subsequently received, the UE may not have sufficient time to perform an uplink transmission handover before the start time of uplink transmission on frequency band D. Therefore, during T0′-T offset Receiving uplink permission for uplink transmission on band D at or before the scheduled uplink transmission can help ensure that the UE has sufficient time to perform a transmission handover to band D before transmission on band D.

[0150] The minimum interval between the end time of the uplink transmission scheduled on band C and the start time of the uplink transmission scheduled on band D may depend on the transmission status after the first handover to band C (e.g., ready to transmit on band C). Timeline 800 relates to a scenario in which one transmission chain (“1Tx”) ​​of the UE is configured to operate on band C, and timeline 810 relates to a scenario in which two transmission chains (“2Tx”) of the UE are configured to operate on band C.

[0151] Referring to timeline 800, band D can be an associated band of band C. This means that when a transmit chain is configured to operate on band C, another transmit chain of the UE can be configured to operate on band D. Therefore, if band D is an associated band of band C, the minimum interval time can be zero, which allows the UE to transmit uplink data with low latency.

[0152] Referring back to timeline 800, band C may have an associated band (e.g., not an associated band of band D), meaning that when a transmit chain is configured to operate on band C, another transmit chain of the UE may be configured to operate on that associated band. Therefore, in this case, the minimum interval time may be based at least in part on the handover period associated with the handover from the associated band to band D. For example, the minimum interval time may be the handover period associated with the handover from the associated band to band D. This handover period may be reported by the UE to the network node. Making the minimum interval time at least in part based on the handover period associated with the handover from the associated band to band D helps ensure that the UE has sufficient time to perform a transmit handover when band C has an associated band (e.g., not an associated band of band D).

[0153] Referring again to timeline 800, in other cases (e.g., when band C has no associated band), the minimum interval time may be based at least in part on the smallest of the following: a first handover period associated with a first handover from band A to band D; a second handover period associated with a second handover from band B to band D; and a third handover period associated with a third handover from band C to band D. For example, the minimum interval time may be the largest of the first, second, and third handover periods. The first, second, and third handover periods may be reported by the UE to the network node. Making the minimum interval time at least in part based on the largest of the first, second, and third handover periods helps ensure that the UE has sufficient time to perform a transmission handover when band C has no associated band.

[0154] Referring to timeline 810, the minimum interval between the end time of a scheduled uplink transmission on band C and the start time of a scheduled uplink transmission on band D can be at least partially based on the handover period associated with the handover from band C to band D. For example, the minimum interval can be the handover period associated with the handover from band C to band D. This handover period can be reported by the UE to the network node. Making the minimum interval at least partially based on the handover period associated with the handover from band C to band D helps ensure that, during transmission on band C, the UE has sufficient time to perform a transmission handover if both transmission chains are configured on band C.

[0155] As indicated above, Figure 8 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 8 The examples described are different.

[0212] Figure 14This is a diagram of an example device 1400 for wireless communication according to the present disclosure.

For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or processor to perform the function or operation of the component.

[0214] Receiver 1402 may receive communications from device 1408, such as reference signals, control information, data communications, or combinations thereof. Receiver 1402 may provide the received communications to one or more other components of device 1400. In some aspects, receiver 1402 may perform signal processing on the received communications (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, etc.) and may provide the processed signals to the one or more other components of device 1400.

The network interface may be configured to acquire and / or output signals for device 1400 via one or more communication links (such as backhaul links, midhaul links, and / or fronthaul links).

[0215] Transmitting component 1404 may transmit communications, such as reference signals, control information, data communications, or combinations thereof, to device 1408. In some aspects, one or more other components of device 1400 may generate communications and provide the generated communications to transmitting component 1404 for transmission to device 1408. In some aspects, transmitting component 1404 may perform signal processing (such as filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding, etc.) on the generated communications and may transmit the processed signals to device 1408. In some aspects, transmitting component 1404 may include combinations of... Figure 2 The described network node includes one or more antennas, modems, modulators, transmit MIMO processors, transmit processors, controllers / processors, memory, or combinations thereof. In some aspects, the transmit component 1404 may be co-located with the receive component 1402 in a transceiver.

[0216] The communication manager 1406 may support the operation of the receiving component 1402 and / or the transmitting component 1404. For example, the communication manager 1406 may receive information associated with configuring the reception of communications by the receiving component 1402 and / or the transmission of communications by the transmitting component 1404. Additionally or alternatively, the communication manager 1406 may generate control information and / or provide control information to the receiving component 1402 and / or the transmitting component 1404 to control the reception and / or transmission of communications.

[0217] The communication manager 1406 can establish a connection with the UE. When the UE is configured to transmit on a first frequency band and a second frequency band, the transmission component 1404 can output one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission overlap in time, and wherein the one or more uplink grants are received by the UE at a time no later than an offset from the earliest start time of the first uplink transmission and the second uplink transmission, wherein the offset is at least partially based on the third frequency band and the fourth frequency band.

[0218] The communication manager 1406 can establish a connection with the UE. When the UE is configured to transmit on a first frequency band and a second frequency band, the transmission component 1404 can output one or more uplink grants that schedule a first uplink transmission on a third frequency band and a second uplink transmission on a fourth frequency band, wherein the first uplink transmission and the second uplink transmission do not overlap in time, and wherein the one or more uplink grants schedule the second uplink transmission at least in part based on the minimum interval between the end time of the first uplink transmission and the start time of the second uplink transmission.

[0219] Figure 14 The number and arrangement of components shown are provided as an example. In reality, they can exist in... Figure 14 The components shown are compared to additional components, fewer components, different components, or components arranged in a different manner. Furthermore, Figure 14 The two or more components shown can be implemented within a single component, or Figure 14 The single component shown can be implemented as multiple distributed components. Additionally or alternatively, Figure 14 The collection of (one or more) components shown is executable and described as being composed of Figure 14 Another set of components shown performs one or more functions.

[0220] Figure 15 and Figure 16 This involves scheduling uplink transmissions that overlap in time across multiple frequency bands for misaligned handovers (e.g., as described above in conjunction with...). Figure 5 As described). Figure 15 and Figure 16 As shown, one or more uplink grants (e.g., DCI) may instruct UE 120 to switch from bands A and B to bands C and D. For example, the one or more uplink grants may not explicitly identify the source-target band pair. In some examples, the baseline UE may not perform one or more band switching operations according to Examples 1500 and / or 1600.

[0221] Figure 15 This is a diagram illustrating an example timeline 1500 for orderly scheduling of time-overlapping uplink transmissions across multiple frequency bands according to this disclosure. For example, as... Figure 15 As shown, UE 120 receives a DCI scheduled for an uplink with an earlier start time before receiving a DCI scheduled for an uplink transmission with a later start time. Figure 15 In the example, neither frequency band C nor frequency band D is associated with any other frequency band.

[0222] As explained above, the uplink grant can be received at a time no later than the offset from the earliest start time of the first and second uplink transmissions. For example, the scheduling deadline (“uplink grant deadline”) can be T0-Toffset, where T0 is the start of the first uplink transmission (e.g., the first PUSCH transmission) after the handover. UE 120 may not be configured or scheduled to handover after the uplink grant deadline.

[0223] UE 120 may examine the associated frequency bands of band C to determine which handover cycle value to use. In some examples, Toffset may be based at least in part on (e.g., may be equal to) the sum of: the largest of the handover cycle associated with a handover from band A to band C and the largest of the handover cycle associated with a handover from band B to band C; and the largest of the handover cycle associated with a handover from band A to band D and the largest of the handover cycle associated with a handover from band B to band D. In some examples, Toffset may be based at least in part on (e.g., may be equal to) the largest of: the handover cycle associated with a handover from band A to band C; the handover cycle associated with a handover from band A to band D; the handover cycle associated with a handover from band B to band C; and the handover cycle associated with a handover from band B to band D. In some examples, from the perspective of UE 120, granting a delay for an earlier transmission may lead to an error condition. UE 120 can preview on band D, and UE 120 can be left unconfigured to schedule a handover after a certain amount of time (e.g., a time slot).

[0224] Figure 16 This is a diagram illustrating an example timeline 1600 for out-of-order scheduling of time-overlapping uplink transmissions across multiple frequency bands according to this disclosure. For example, as... Figure 16 As shown, UE 120 receives a DCI scheduled for uplink transmission with an earlier start time after receiving a DCI scheduled for uplink transmission with a later start time.
