In some aspects, a user equipment (UE) can determine whether the number of downlink control information (DCI) sets monitored by the UE satisfies a threshold for a secondary cell and a primary cell where cross-carrier scheduling from secondary cell to primary cell will occur, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold. The UE can selectively perform a DCI size alignment process to adjust the DCI size configuration, at least in part based on whether the number of DCI sizes satisfies the threshold. The UE can monitor the DCI set at least in part based on the DCI size configuration. Numerous other aspects are provided.

Technical Field

[0003] In summary, various aspects of this disclosure relate to wireless communication, and specifically to techniques and apparatus for configuring downlink control information size in cross-carrier scheduling scenarios. Background Technology

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

[0005] A wireless network may include one or more base stations that support communication for one or more user equipment (UE) devices. The UE may communicate with the base station via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the base station to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the base station.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol 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 an enhancement set to the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation, thereby better supporting mobile broadband internet access. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0007] In some aspects, a method of wireless communication performed by a user equipment (UE) includes: determining, for the secondary cell and the primary cell in which cross-carrier scheduling from the secondary cell to the primary cell will occur, whether the number of DCI sizes in a set of downlink control information (DCI) monitored by the UE meets a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold; selectively performing a DCI size alignment process to adjust the DCI size configuration, at least in part based on whether the number of DCI sizes meets the threshold; and monitoring the set of DCIs, at least in part based on the DCI size configuration.

[0008] In some aspects, a UE for wireless communication includes: a memory and one or more processors operatively coupled to the memory, the memory and the one or more processors being configured to: determine, for the secondary cell and the primary cell in which cross-carrier scheduling from the secondary cell to the primary cell will occur, whether the number of DCI sizes in a set of DCIs monitored by the UE satisfies a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold; selectively perform a DCI size alignment process to adjust the DCI size configuration, at least in part based on whether the number of DCI sizes satisfies the threshold; and monitor the set of DCIs, at least in part based on the DCI size configuration.

[0009] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes: one or more instructions that, when executed by one or more processors of a UE, cause the UE to: determine, for the secondary cell and the primary cell in which cross-carrier scheduling from the secondary cell to the primary cell will occur, whether the number of DCI sizes of a DCI set monitored by the UE satisfies a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold; selectively perform a DCI size alignment process to adjust the DCI size configuration, at least in part based on whether the number of DCI sizes satisfies the threshold; and monitor the DCI set, at least in part based on the DCI size configuration.

[0010] In some aspects, an apparatus for wireless communication includes: a unit for determining, for the secondary cell and the primary cell in which cross-carrier scheduling from the secondary cell to the primary cell will occur, whether the number of DCI sizes in a DCI set monitored by the apparatus meets a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold; a unit for selectively performing a DCI size alignment process to adjust the DCI size configuration based at least in part on whether the number of DCI sizes meets the threshold; and a unit for monitoring the DCI set at least in part based on the DCI size configuration.

[0011] In general, the aspects include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication equipment and / or processing systems as fully described herein with reference to the accompanying drawings and description and as shown by the accompanying drawings and description.

[0022] The 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. It will be understood by those skilled in the art that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or a method may be implemented using any number of the aspects set forth herein.

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

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

[0024] While this document may use terms commonly associated with 5G or New Radio (NR) Radio Access Technology (RAT) to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0025] Figure 1This is a schematic diagram illustrating an example of a wireless network 100 according to this disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, as well as other examples. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity that communicates with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a Transmit / Receive Point (TRP). Each base station 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term “cell” can refer to the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0026] Base station 110 can provide communication coverage for macro cells, pico cells, femtocells, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 120 with service subscriptions. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UE 120 with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a Closed User Group (CSG)). Base station 110 for macro cells can be referred to as a macro base station. Base station 110 for pico cells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS 110a can be a macro base station for macro cell 102a, BS 110b can be a pico base station for pico cell 102b, and BS 110c can be a femto base station for femto cell 102c. A base station can support one or more (e.g., three) cells.

[0027] In some examples, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base stations 110 may be interconnected with each other and / or with one or more other base stations 110 or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0028] Wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., base station 110 or UE 120) and transmit the data transmissions to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 capable of relaying transmissions for other UE 120s. Figure 1 In the example shown, BS 110d (e.g., a relay base station) can communicate with BS 110a (e.g., a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. The base station 110 for relay communication may be referred to as a relay station, relay base station, relay, etc.

[0029] Wireless network 100 can be a heterogeneous network comprising different types of base stations 110 (such as macro base stations, pico base stations, femto base stations, relay base stations, etc.). These different types of base stations 110 can have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations can have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0030] Network controller 130 can be coupled to or communicate with a group of base stations 110, and can provide coordination and control for these base stations 110. Network controller 130 can communicate with base stations 110 via backhaul communication links. Base stations 110 can communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0031] 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 user units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric 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 unit), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, and / or any other suitable device configured to communicate via a wireless medium.

[0032] Some UEs 120 can 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, which can communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 can be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 can 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.

[0033] Typically, 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 can be referred to as a radio technology, air interface, etc. A frequency can be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0034] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, 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 herein as being performed by base station 110.

[0035] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency range names FR1 (410MHz–7.125GHz) and FR2 (24.25GHz–52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “below 6GHz” band in various documents and articles. Similar naming issues sometimes arise regarding FR2; although it differs from the extremely high frequency (EHF) band (30GHz–300GHz), it is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, while the EHF band is identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0036] The frequencies between FR1 and FR2 are often referred to as intermediate frequency (IF) frequencies. Recent 5G NR studies have identified the operating bands for these IF frequencies as the frequency range name FR3 (7.125 GHz – 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the characteristics of FR1 and / or FR2 into the IF frequency range. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating frequency bands have been identified as the frequency range names FR4a or FR4-1 (52.6 GHz – 71 GHz), FR4 (52.6 GHz – 114.25 GHz), and FR5 (114.25 GHz – 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0037] Considering the examples above, unless otherwise specifically stated, it should be understood that, if used herein, the terms "below 6 GHz," etc., can broadly refer to frequencies that are less than 6 GHz, within FR1, or may include intermediate frequency bands. Furthermore, unless otherwise specifically stated, it should be understood that, if used herein, the terms "millimeter wave," etc., can broadly refer to frequencies that may include intermediate frequency bands, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is anticipated that the frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0038] In some aspects, UE 120 may include communication manager 140. As described in more detail elsewhere herein, communication manager 140 may, for the secondary and primary cells where cross-carrier scheduling from secondary to primary cell will occur, determine whether the number of DCI sizes in the set of downlink control information (DCI) monitored by UE 120 meets a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold; selectively perform a DCI size alignment process to adjust the DCI size configuration, at least in part based on whether the number of DCI sizes meets the threshold; and monitor the DCI set, at least in part based on the DCI size configuration. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

[0039] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0040] Figure 2 This is a schematic diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0041] At base station 110, transmitting processor 220 can receive data from data source 212 intended for UE 120 (or a set of UE 120). Transmitting processor 220 can select one or more modulation and coding schemes (MCS) for UE 120, at least in part, based on one or more channel quality indicators (CQIs) received from UE 120. UE 120 can process (e.g., code and modulate) the data for UE 120, and provide data symbols for UE 120, at least in part, based on the MCS selected for UE 120. Transmitting processor 220 can process system information (e.g., semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, permission, 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 signals (CRS) or demodulation reference signals (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., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, 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 its respective modulator component to process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use its respective modulator component to process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0042] At UE 120, an array of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110, and can provide a set of received signals (e.g., R received signals) to an array 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 its respective 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, can perform MIMO detection on the received symbols (if applicable), and can provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control and system information to the controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0043] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0044] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or may be included within the following: one or more antenna panels, one or more antenna groups, one or more antenna element sets, and / or one or more antenna arrays, and other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), coplanar antenna element sets, non-coplanar antenna element sets, and / or coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0045] On the uplink, at UE 120, 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). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include modulator and demodulator. In some examples, UE 120 includes a transceiver. 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 perform aspects of any of the methods described herein (e.g., refer to...). Figures 5-7 ).

[0046] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., refer to...). Figures 5-7 ).

[0047] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2Any other components may perform one or more techniques associated with DCI size configuration in cross-carrier scheduling scenarios, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 6 The operation of process 600 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 6 The operation of process 600 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions, and / or interpretation instructions, as well as other examples.

[0048] In some aspects, the UE (e.g., UE 120) includes: a unit for determining, for a secondary cell and a primary cell in which cross-carrier scheduling from the secondary cell to the primary cell will occur, whether the number of DCI sizes in the DCI set monitored by the UE meets a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold; a unit for selectively performing a DCI size alignment process to adjust the DCI size configuration based at least in part on whether the number of DCI sizes meets the threshold; and / or a unit for monitoring the DCI set based at least in part on the DCI size configuration. The unit for the UE to perform the operations described herein may include, for example, one or more of the following: 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.

[0049] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of controller / processor 280.

[0050] As pointed out above, Figure 2This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0051] In some communication systems, the UE may not be required to process more than a threshold number of DCI size types. For example, the UE may be configured to monitor four or fewer different DCI sizes for a cell. Alternatively, the UE may be configured to monitor three or fewer DCI sizes for which Cell Radio Network Temporary Identifiers (C-RNTIs) are configured. However, as a result of higher-level configuration, the UE may determine that more than a threshold number of DCI sizes are configured for the cell (e.g., more than four DCI sizes, more than three DCI sizes for which C-RNTIs are configured, etc.). In such cases, the UE can perform a DCI size alignment procedure as described herein.

[0052] Figure 3A and 3B This is a schematic diagram illustrating example 300 of DCI size alignment according to this disclosure.

[0053] As in Figure 3A As shown in step 305, the UE can determine the first size (size A) of the Common Search Space (CSS) DCI 0_0 and CSS DCI 1_0 (if CSS DCI 0_0 or CSS DCI 1_0 is configured respectively). In some cases, the UE can align the size of CSS DCI 0_0 with that of CSS DCI 1_0. For example, when CSS DCI 0_0 has a larger size than CSS DCI 1_0, the UE can add a set of zero-padding bits to CSS DCI 0_0 until the payload size equals the payload size of DCI 1_0. Conversely, if CSS DCI 0_0 has a smaller size than CSS DCI 1_0 before truncation, the UE can reduce the bit width of the Frequency Domain Resource Assignment (FDRA) field in DCI 0_0 by truncating the first few most significant bits, making the size of DCI 0_0 equal to the size of DCI 1_0.

[0054] As in Figure 3A Furthermore, as shown in step 310, the UE can determine a second size (size B) of the UE-specific search space (USS) DCI 0_0 and USS DCI 1_0 (if USS DCI 0_0 or USS DCI 1_0 is configured respectively). In some cases, the UE can align USS DCI 0_0 and USS DCI 1_0 with a common size by adding padding bits to the smaller of USS DCI 0_0 and USS DCI 1_0.

[0055] As in Figure 3A Furthermore, as shown in step 315, the UE can determine the third size (size C) of USS DCI 0_1 and the fourth size (size D) of USS DCI 1_1 (if USS DCI 0_1 or USS DCI 1_1 is configured respectively). In some cases, the UE can determine size C and / or size D based at least in part on size B. For example, the UE can set size C and / or size D to be one bit larger than size B.

[0056] As in Figure 3A Furthermore, as shown in step 320, the UE can determine the fifth size (size E) of USS DCI 0_2 and the sixth size (size F) of USS DCI 1_2 (if USS DCI 0_2 or USS DCI 1_2 is configured respectively).

[0057] As in Figure 3B Furthermore, as shown in step 325, the UE can determine whether a size threshold is met. For example, based at least in part on which DCIs are configured for the UE, the UE can determine the number of DCI sizes. In other words, if CSS DCI0_0 (size A), CSS DCI1_0 (size A), USS DCI0_1 (size C), and USS DCI0_2 (size E) are configured, then there are three DCI sizes. Conversely, if CSS DCI0_0 (size A), USS DCI0_0 (size B), USS DCI0_1 (size C), and USS DCI0_2 (size E) are configured, then there are four DCI sizes. Based at least in part on determining the number of DCI sizes, the UE can determine whether there are more than four or more than three DCI sizes configured with C-RNTI. If neither DCI size threshold is met, the UE can continue without performing further steps for DCI size alignment. However, if any DCI size threshold is met, the UE can perform further steps for DCI size alignment, as described in this paper. Figure 3B And as described in steps 330-340.

[0058] As in Figure 3BFurthermore, as shown in step 330, the UE can perform a first set of size alignment actions. For example, the UE can maintain CSS DCI 0_0 and CSS DCI 1_0 (if configured) at size A; the UE can align USS DCI0_0 and / or USS DCI 1_0 (if configured) with size A (e.g., using padding bits or truncating existing bits); the UE can remove the added bits in USS DCI 0_1 and USS DCI 1_1 (if configured) added in step 315, and the UE can maintain the size of USS DCI 0_2 and USS DCI 1_2 (if configured).

[0059] As in Figure 3B Furthermore, as shown in step 335, the UE can perform a second set of alignment actions. For example, the UE can maintain CSS DCI 0_0, CSS DCI 1_0, USS DCI 0_0, USS DCI 1_0, USS DCI 0_1, and USSDCI 1_1 (if configured); and can align USS DCI 0_2 with USS DCI 1_2 (if configured) by adding padding bits to one or the other so that USS DCI 0_2 and USS DCI 1_2 have a common size (e.g., size E or size F).

[0060] As in Figure 3B Furthermore, as shown in step 340, the UE can perform a third set of alignment actions. For example, the UE can maintain CSS DCI 0_0, CSS DCI 1_0, USS DCI 0_0, USS DCI 1_0, USS DCI 0_2, and USSDCI 1_2 (if configured); and can align USS DCI 0_1 with USS DCI 1_1 (if configured) by adding padding bits to one or the other to make USS DCI 0_1 and USS DCI 1_1 have a common size (e.g., size C or size D). In some cases, the UE can repeat the check of step 325 after each of steps 330, 335, and 340. In other cases, the UE can perform multiple steps 330, 335, and / or 340 before repeating the check of step 325. After performing the size alignment process, the UE ensures that the DCI size threshold is met, which enables the UE to successfully monitor the configured DCI.

[0061] As pointed out above, Figure 3A and 3B This is provided as an example. Other examples may differ from the one provided. Figure 3A and 3B The example described.

[0062] Figure 4 This is a schematic diagram illustrating example 400 of cross-carrier scheduling according to this disclosure. Figure 4 As shown, Example 400 may include: a secondary cell (SCell), which is a non-dynamic spectrum sharing (DSS) carrier for communication between the BS and the UE, wherein the subcarrier spacing (SCS) is, for example, 15 kHz or 30 kHz; and a primary cell or primary-secondary cell P(S)Cell, which is a DSS carrier for communication between the BS and the UE, wherein the SCS is, for example, 15 kHz. In some cases, the SCell may be an NR unlicensed spectrum (NR-U) carrier.

[0063] As in Figure 4 As shown by reference numeral 410, a first example of cross-carrier scheduling may include the BS transmitting a DCI of a specific format on the SCell to schedule Physical Downlink Shared Channel (PDSCH) communication or Physical Uplink Shared Channel (PUSCH) communication on the P(S)Cell. As shown by reference numeral 420, a second example of cross-carrier scheduling may include the BS transmitting a DCI on the SCell to schedule a first PDSCH communication on the SCell and a second PDSCH communication on the P(S)Cell. A second example of cross-carrier scheduling may be a joint scheduling scenario (e.g., a scenario in which both cross-carrier scheduling and self-scheduling occur).

[0064] As pointed out above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0065] In some communication systems, a serving cell can be scheduled using only communication on that serving cell, such as by using only self-scheduling or only cross-carrier scheduling. In other words, an SCell can schedule a P(S)Cell, or an SCell can self-schedule. However, in cross-carrier scheduling scenarios from an SCell to the primary cell (PCell), using only cross-carrier scheduling may not be feasible. For example, the DCI format configured for scheduling system information or paging procedures, random access procedures, backoff procedures, etc., may only be available in self-scheduling scenarios. In this case, using only cross-carrier scheduling may prevent the use of the DCI format configured for the aforementioned procedures. Therefore, due to the failure to configure the aforementioned procedures, using only cross-carrier scheduling may result in poor network performance.

[0066] Several techniques have been introduced to allow cross-carrier scheduling and self-scheduling for the same serving cell. For example, corresponding DCIs on SCell and PCell can schedule communications (e.g., PDSCH or PUSCH) on PCell. For instance, a first DCI on SCell can schedule unicast data transmission on PCell, and a second DCI on PCell can configure and / or schedule system information or paging procedures, random access procedures, fallback procedures, etc., on PCell. However, enabling both cross-carrier scheduling and self-scheduling for the same serving cell may introduce an additional number of DCI sizes for the additional DCI formats that the UE can monitor when operating in cross-carrier scheduling and self-scheduling scenarios.

[0067] The aspects described in this paper implement DCI size alignment for such situations, enabling the UE to operate in cross-carrier scheduling and self-scheduling scenarios without exceeding a DCI size threshold. For example, the UE can determine whether the DCI size threshold is met on a per-scheduled-cell or per-scheduled-cell basis. In this case, based at least in part on the determination that the DCI size threshold is met, the UE can trigger a DCI size alignment process as described in this paper. In this way, the UE achieves operation in cross-carrier scheduling and self-scheduling scenarios.

[0068] Figure 5 This is a schematic diagram illustrating example 500 associated with DCI size configuration in a cross-carrier scheduling scenario according to the present disclosure. Figure 5 As shown, Example 500 includes communication between one or more BS 110s and UE 120. In some aspects, one or more BS 110s and UE 120s may be included in a wireless network (such as wireless network 100). One or more BS 110s and UE 120s may communicate on a radio access link, which may include an uplink and a downlink.

[0069] As in Figure 5As further illustrated by reference numeral 510 in the accompanying drawing, UE 120 can determine whether the number of DCI sizes meets a DCI size threshold. In some aspects, UE 120 can determine whether the number of DCI sizes meets a DCI size threshold on a per-scheduled-cell basis. For example, UE 120 can determine whether the number of first DCI sizes of DCI formats used for scheduling data on the PCell monitored on the PCell meets a threshold (e.g., up to 4 total DCI sizes or 3 DCI sizes configured with C-RNTI, as described above) and / or whether the number of second DCI sizes of DCI formats used for scheduling data on the PCell monitored on the SCell meets a threshold (e.g., up to 4 additional total DCI sizes or 3 DCI sizes configured with C-RNTI, as described above). In this case, if UE 120 detects that at least one of the first DCI size number or the second DCI size number meets the threshold, UE 120 can trigger a DCI size alignment process, as described above. In this way, for each scheduled cell, the UE 120 achieves a DCI size of up to one times the threshold number, where the multiple is the number of scheduled cells for the scheduled cell.

[0070] In some aspects, UE 120 can determine whether the number of DCI sizes meets a DCI size threshold on a per-scheduled cell basis. For example, UE 120 can determine whether the total number of DCI sizes for DCI formats used to schedule data on the PCell, monitored by UE 120 on both the PCell and SCell, meets a threshold. In this case, if the total number of DCI formats used to schedule data on the PCell across the PCell and SCell meets the threshold (e.g., up to 4 total DCI sizes or 3 DCI sizes configured with C-RNTI, as described above), UE 120 can trigger a DCI size alignment process, as described above. In some aspects, UE 120 can share the DCI size threshold across scheduled cells without restriction. For example, UE 120 may allow DCI size splits between two scheduled cells, with the DCI size splitting into (0, 3), (1, 2), (2, 1), or (3, 0) for a DCI with a C-RNTI, and into (0, 4), (1, 3), (2, 2), (3, 1), or (4, 0) for a DCI without a C-RNTI. Conversely, in some cases, UE 120 may share DCI size thresholds across scheduled cells based on a fixed set of thresholds. For example, UE 120 may allow only a subset of the aforementioned DCI size splits between two scheduled cells. In this case, each scheduled cell has a threshold separate from each other scheduled cell, and UE 120 may perform DCI size alignment for one or more scheduled cells based at least in part on determining that the respective thresholds are met. While some aspects are described with respect to two scheduled cells and a single scheduled cell, other configurations are possible, such as more than two scheduled cells, more than one scheduled cell, etc.

[0071] As in Figure 5As further shown by reference numeral 520, UE 120 can selectively perform a DCI size alignment process, at least in part, based on whether the number of DCI sizes meets a DCI size threshold. For example, UE 120 can perform a DCI size alignment process when the number of DCI sizes (e.g., on a per-cell-per-scheduled-cell basis or on a per-cell-per-scheduled-cell basis) meets a threshold. As an example of determining whether the number of DCI sizes meets a DCI size threshold on a per-cell-per-scheduled-cell basis, UE 120 can monitor CSS DCI 0_0 or 1_0 and USS DCI 0_0 or 1_0 on the PCell (resulting in 1 or 2 DCI sizes with C-RNTI), and can monitor DCI 2_0, 2_1, 2_2, 2_3 or 2_4 with configurable sizes (resulting in an additional 1 DCI size). Further regarding this example, on the SCell, UE 120 can monitor USS 0_1 or 1_1 and USS 0_2 or 1_2 (this could result in more than 3 DCI sizes with C-RNTI). In this example, UE 120 can align the DCI sizes of DCI 0_2 and 1_2 at step 335 of the DCI size alignment process in Figure 3 by adding padding bits to the smaller of DCI 0_2 and 1_2. Alternatively, UE 120 can align the DCI sizes of DCI 0_1 and 1_1 at step 340 of the DCI size alignment process in Figure 3 by adding padding bits to the smaller of DCI 0_1 and 1_1.

[0072] As in Figure 5 As further illustrated by reference numeral 530, UE 120 can monitor the DCI set at least in part based on selectively performing a DCI size alignment process. For example, UE 120 can monitor the DCI set scheduled for data on a PCell within the resources of an SCell or PCell.

[0073] As pointed out above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The described example

[0074] Figure 6 This is a schematic diagram illustrating an example procedure 600 performed by a UE, for example, in accordance with this disclosure. Example procedure 600 is an example in which a UE (e.g., UE 120) performs operations associated with DCI size configuration in a cross-carrier scheduling scenario.

[0075] like Figure 6As shown, in some aspects, process 600 may include: determining, for a secondary cell and a primary cell in which cross-carrier scheduling from secondary cell to primary cell will occur, whether the number of DCI sizes in the DCI set monitored by the UE satisfies a threshold, wherein the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold (block 610). For example, the UE (e.g., using antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280, and / or memory 282) may determine, for a secondary cell and a primary cell in which cross-carrier scheduling from secondary cell to primary cell will occur, whether the number of DCI sizes in the DCI set monitored by the UE satisfies the threshold, as described above. In some aspects, the threshold is a per-scheduled-cell per-scheduled-cell threshold or a per-scheduled-cell threshold.

[0076] like Figure 6 As further shown, in some aspects, process 600 may include selectively performing a DCI size alignment process to adjust the DCI size configuration based at least in part on whether the number of DCI sizes meets a threshold (block 620). For example, a UE (e.g., using antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TXMIMO processor 266, modulator 254, controller / processor 280 and / or memory 282) may selectively perform a DCI size alignment process to adjust the DCI size configuration based at least in part on whether the number of DCI sizes meets a threshold, as described above.

[0077] like Figure 6 As further shown, in some aspects, process 600 may include: monitoring the DCI set at least in part based on the DCI size configuration (block 630). For example, the UE (e.g., using antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller / processor 280 and / or memory 282) may monitor the DCI set at least in part based on the DCI size configuration, as described above.

[0078] Process 600 may include additional aspects, such as any single aspect or any combination thereof described below and / or in conjunction with one or more other process descriptions elsewhere described herein.

[0079] In the first aspect, the threshold is a per-scheduled-cell threshold, and wherein the threshold includes a first threshold for the primary cell and a second threshold for the secondary cell.

[0080] In the second aspect, selectively performing the DCI size alignment process includes performing the DCI size alignment process at least in part based on satisfying at least one of a first threshold or a second threshold.

[0081] In the third aspect, the threshold is a per-scheduled-cell threshold, and wherein the threshold includes a single threshold for the primary cell and the secondary cell.

[0082] In the fourth aspect, selectively performing the DCI size alignment process includes performing the DCI size alignment process at least in part based on satisfying a single threshold.

[0083] In the fifth aspect, the dispatched cells across dispatched cells share a single threshold.

[0084] In the sixth aspect, the DCI size budget associated with a single threshold is split among the scheduling cells used for the scheduled cells, based on a split configuration of static or semi-static configuration.
