[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 956,464, entitled "PHYSICAL DOWNLINK CONTROL CHANNEL (PDCCH) PARAMETERS FOR MULTIPLE CELL GROUPS", filed January 2, 2020, and U.S. Non-Provisional Patent Application No. 16 / 949,930, entitled "PHYSICAL DOWNLINK CONTROL CHANNEL (PDCCH) PARAMETERS FOR MULTIPLE CELL GROUPS", filed November 20, 2020, which are expressly incorporated herein by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communication, and more specifically to techniques for identifying physical downlink control channel (PDCCH) parameters for multiple cell groups. 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 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).

[0005] A wireless communication network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with base stations (BSs) via downlink (DL) and uplink (UL). DL (or forward link) refers to the communication link from the BS to the UE, while UL (or backward link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a NodeB, LTE evolution nodeB (eNB), gNB, access point (AP), radio head, transmit / receive point (TRP), new radio (NR) BS, or 5G NodeB.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate at the municipal, national, regional, and even global levels. NR (which can also be referred to as 5G) is a collection of enhancements to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the DL, using CP-OFDM or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) (or combinations thereof) on the UL, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation to improve spectral efficiency, reduce costs, improve service, utilize new spectrum, and better integrate with other open standards.

[0040] For the purpose of describing the innovative aspects of this disclosure, the following description is directed to certain embodiments. However, those skilled in the art will readily recognize that the teachings herein can be applied in a variety of different ways. Some examples in this disclosure are based on wireless and wired local area network (LAN) communications according to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless standard, the IEEE 802.3 Ethernet standard, and the IEEE 1901 power line communication (PLC) standard. However, the described embodiments can be implemented in any device, system, and network capable of transmitting and receiving radio frequency signals according to any of the wireless communication standards including: the IEEE 802.11 standard, Standard, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), GSM / General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunking Radio (TETRA), Wideband CDMA (W-CDMA), Evolved Data Optimized (EV-DO), 1xEV-DO, EV-DO Rev A, EV-DO Rev B, High-Speed ​​Packet Access (HSPA), High-Speed ​​Downlink Packet Access (HSDPA), High-Speed ​​Uplink Packet Access (HSUPA), Evolved High-Speed ​​Packet Access (HSPA+), Long Term Evolution (LTE), AMPS, or other known signals used for communication within wireless, cellular, or Internet of Things (IoT) networks, such as systems utilizing 3G, 4G, or 5G or further implementations thereof.

[0041] Physical downlink control channel (PDCCH) parameters can be specified for user equipment (UE). PDCCH parameters can include PDCCH blind decoding limits, PDCCH control channel element limits, and other PDCCH parameters instructing the UE on how to perform PDCCH processing. PDCCH blind decoding limits identify the number of blind decodes the UE will perform in a PDCCH slot or a specific span of PDCCH symbols. Blind decoding refers to decoding symbols without knowing whether they actually carry any information (control or data). Similarly, PDCCH control channel element limits identify a specific number of control channel elements the UE will process in a PDCCH slot or a specific PDCCH symbol span. The quantities identified by PDCCH blind decoding limits and PDCCH control channel element limits can be configured to limit or reduce the UE's signal processing burden.

[0042] In some cases, a UE can be configured with multiple cell groups. New Radio (NR) dual connectivity can refer to a deployment where the UE is configured with two cell groups, which can be referred to as a primary cell group and a secondary cell group. Each cell group can include one or more cells, such as a primary cell (or serving cell) and a secondary cell. NR multi-connectivity can refer to a deployment where the UE is configured with more than two cell groups. In this case, the UE can be configured with: a primary cell group and multiple secondary cell groups; multiple primary cell groups and one or more secondary cell groups; and other configuration combinations.

[0043] UEs deployed in dual-connectivity or multi-connectivity configurations may experience challenges in selecting, determining, identifying, or configuring PDCCH parameters such as those described above. For example, when selecting or determining PDCCH blind decoding limits and PDCCH control channel element limits for a UE, the UE may be unable to select or determine which cell groups to consider. As another example, if a UE can communicate across multiple frequency ranges (e.g., 5G frequency range 1 (FR1 or lower 6 GHz), 5G frequency range 2 (FR2 or millimeter wave), and other frequency ranges), the UE may be unable to select or determine how to indicate PDCCH parameters. As yet another example, one or more base stations (such as serving cell base stations) communicating with the UE may be unable to select or determine whether to allow the base station to over-book the UE by configuring the PDCCH on the UE, resulting in a number of blind decodings and control channel elements not supported by the PDCCH parameters selected or determined by the UE.

[0044] Some aspects described herein provide techniques and apparatus for identifying PDCCH parameters, such as PDCCH blind decoding restrictions and PDCCH control channel element restrictions, for implementations in which the UE is configured with multiple (two or more) cell groups.

[0045] Specific implementations of the subject matter described in this disclosure can be implemented to achieve one or more of the following potential advantages. The techniques described herein can allow the UE to select or determine the number of cell groups to consider when selecting or determining PDCCH parameters, which can improve the accuracy of PDCCH parameters. The techniques described herein can allow the UE to indicate PDCCH parameters across multiple frequency ranges, which can improve the flexibility of the UE in signaling PDCCH parameters. The techniques described herein can allow different cell groups, different types of cell groups, or other configured cell groups (or cells within cell groups) to be configured with a number of PDCCH candidates corresponding to the number of blind decodings exceeding the PDCCH blind decoding limit, which can improve the flexibility of the UE's PDCCH configuration. The techniques described herein can also allow different cell groups, different types of cell groups, or other configured cell groups (or cells within cell groups) to be configured with a number of PDCCH candidates exceeding the UE's PDCCH control channel element limit, which can improve the flexibility of the UE's PDCCH configuration.

[0046] Figure 1This is a block diagram conceptually illustrating an example of a wireless network 100. Wireless network 100 can be an LTE network or some other wireless network, such as a 5G or NR network. Wireless network 100 can include multiple BS 110s (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and can also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, or Transmit / Receive Point (TRP). Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" can refer to the coverage area of ​​a BS, a BS subsystem serving that coverage area, or a combination thereof, depending on the context in which the term is used.

[0047] A BS can provide communication coverage for macrocells, picocells, femtocells, another type of cell, or a combination thereof. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with a service subscription. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow unrestricted access by UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NRBS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0048] In some examples, the cell may not be fixed, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some examples, BSs may interconnect with each other and with one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces such as direct physical connections, virtual networks, or combinations thereof.

[0049] The wireless network 100 may also include relay stations. A relay station is an entity that receives data transmissions from an upstream station (e.g., a BS or a UE) and forwards data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, relay base station, relay, etc.

[0050] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (such as 5 to 40 watts or another example), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0051] Network controller 130 can be coupled to a set of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. The BSs can also communicate with each other via wireless or wired backhaul (e.g., direct or indirect communication).

[0052] UEs 120 (e.g., 120a, 120b, 120c, etc.) may be distributed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or medical equipment, a biometric sensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio, etc.), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0053] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to, for example, a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links. Some UEs can be considered Internet of Things (IoT) devices, or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that encloses components of UE 120, such as processor components, memory components, similar components, or combinations thereof.

[0054] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0055] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., a base station) allocates resources for communication among some or all devices and equipment within the scheduling entity's service area or cell. Within this disclosure, as further discussed below, the scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communication, the subordinate entities utilize the resources allocated by the scheduling entity.

[0056] A base station is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity that schedules resources for one or more subordinate entities (e.g., one or more other UEs). In this example, the UE acts as the scheduling entity, and other UEs utilize the resources scheduled by the UE for wireless communication. A UE can act as a scheduling entity in a peer-to-peer (P2P) network, a mesh network, or another type of network. In a mesh network example, in addition to communicating with a scheduling entity, UEs can optionally communicate directly with each other.

[0057] Therefore, in a wireless communication network with scheduled access to time-frequency resources and with cellular, P2P, and mesh configurations, a scheduling entity and one or more subordinate entities can communicate using the scheduled resources.

[0058] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidechain channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UE 120 may use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or similar protocols), mesh networks or similar networks, or combinations thereof. In this case, UE 120 may perform scheduling operations, resource selection operations, and other operations described elsewhere herein as being performed by base station 110.

[0059] Figure 2 This is a block diagram conceptually illustrating example 200 of base station 110 and UE 120 in communication. In some aspects, base station 110 and UE 120 can be respectively Figure 1 One of the base stations and one of the UEs in the wireless network 100. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T≤1 and R≤1.

[0060] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from the UE, process the data for each UE (e.g., encode and modulate the data) based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.) and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its own output symbol stream (e.g., for OFDM, etc.) to obtain a sampled stream of output. Each modulator 232 can further process the sampled stream of output (e.g., convert it to analog, amplify it, filter it, and up-convert it) to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted separately via T antennas 234a to 234t. Position coding can be used to generate synchronization signals to convey additional information, according to various aspects described in more detail below.

[0061] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 or other base stations and can provide the received signals to demodulators 254a to 254r respectively. Each demodulator 254 can adjust the received signal (e.g., filter, amplify, down-convert, and digitize it) to obtain a sample of the input. Each demodulator 254 can further process the sampled input (e.g., for OFDM, etc.) to obtain the received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receiver processor 258 can process the detected symbols (e.g., demodulate and decode them), provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller or processor (controller / processor) 280. The channel processor can determine the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), Channel Quality Indicator (CQI), etc. In some respects, one or more components of the UE 120 may be included in the housing.

[0062] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-coded by the TX MIMO processor 266 (if applicable), further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.) and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiving processor 238 to obtain decoded data and control information transmitted by UE 120. The receiving processor 238 can provide the decoded data to the data sink 239 and the decoded control information to the controller or processor (i.e., controller / processor) 240. The base station 110 may include a communication unit 244 and communicates with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller or processor (i.e., controller / processor) 290, and a memory 292.

[0063] In some implementations, the controller / processor 280 may be a component of a processing system. A processing system can generally refer to a system or a series of machines or components that receive and process inputs to produce a set of outputs (which can be passed to, for example, other systems or components of UE 120). For example, the processing system of UE 120 can refer to a system that includes various other components or sub-components of UE 120.

[0064] The processing system of UE 120 can interface with other components of UE 120 and can process information (such as inputs or signals) received from other components, output information to other components, etc. For example, the chip or modem of UE 120 may include a processing system, a first interface configured to receive or acquire information, and a second interface configured to output, transmit, or provide information. In some cases, the first interface may refer to the interface between the processing system of the chip or modem and the receiver, allowing UE 120 to receive information or signal input and to transmit information to the processing system. In some cases, the second interface may refer to the interface between the processing system of the chip or modem and the transmitter, allowing UE 120 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface can also acquire or receive information or signal input, and the first interface can also output, transmit, or provide information.

[0065] In some implementations, the controller / processor 240 may be a component of a processing system. A processing system can generally refer to a system or a series of machines or components that receive and process inputs to produce a set of outputs (which may be passed to, for example, other systems or components of BS 110). For example, the processing system of BS 110 can refer to a system that includes various other components or sub-components of BS 110.

[0066] The processing system of BS 110 can interface with other components of BS 110 and can process information (such as inputs or signals) received from other components, output information to other components, etc. For example, the chip or modem of BS 110 may include a processing system, a first interface configured to receive or acquire information, and a second interface configured to output, transmit, or provide information. In some cases, the first interface may refer to the interface between the processing system of the chip or modem and the receiver, allowing BS 110 to receive information or signal input and to transmit information to the processing system. In some cases, the second interface may refer to the interface between the processing system of the chip or modem and the transmitter, allowing BS 110 to transmit information output from the chip or modem. Those skilled in the art will readily recognize that the second interface can also acquire or receive information or signal input, and the first interface can also output, transmit, or provide information.

[0067] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 or Figure 2 Any other component may perform one or more techniques associated with identifying PDCCH parameters for multiple cell groups, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, or... Figure 2 Any other component (or combination of components) can perform or direct, for example Figure 5 Processing 500 Figure 6 The system can process 600 or other processes as described herein. Memory 242 and 282 can store data and program code for base station 110 and UE 120, respectively. Scheduler 246 can schedule the UE to transmit data on the downlink, uplink, or a combination thereof.

[0068] The stored program code, when executed by the controller / processor 280 or other processors and modules at the UE 120, enables the UE 120 to perform actions related to... Figure 5 Processing 500 Figure 6 Processing 600 Figure 7 The stored program code, when executed by the controller / processor 240 or other processors and modules at the base station 110, enables the base station 110 to perform operations related to processing 700 or other processing described herein. Figure 5 Processing 500 Figure 6 Processing 600 Figure 7 The process 700 or other processes described herein may be used. Scheduler 246 may schedule the UE to transmit data on the downlink, uplink, or a combination thereof.

[0069] In some aspects, UE 120 may include: components for identifying the PDCCH blind decoding capability value and the PDCCH control channel element capability value of UE 120; and components for determining (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits associated with the PDCCH blind decoding capability value, the PDCCH control channel element capability value, and the number of cell groups configured for the UE or the number of cell groups activated for the UE, or combinations thereof. In some aspects, UE 120 may include: components for determining (which may include selection) a respective number of cell references for each cell group configured for the UE, wherein the UE is configured with two or more cell groups; and components for determining (which may include selection) a respective number of PDCCH blind decoding limits and a respective number of PDCCH control channel element limits, or combinations thereof, associated with the respective number of cell references for each cell group configured for the UE. In some aspects, such components may include combinations of Figure 2 One or more components of the UE 120 described.

[0070] In some aspects, base station 110 may include: components for receiving PDCCH blind decoding capability values ​​and PDCCH control channel element capability values ​​of UE 120; and components for determining (which may include selecting) PDCCH blind decoding limits and PDCCH control channel element limits for UE 120 associated with the PDCCH blind decoding capability values, PDCCH control channel element capability values, and the number of cell groups configured for UE 120 or the number of cell groups activated for UE 120, or combinations thereof.

[0071] Although Figure 2 The blocks are shown as different components, but the functions described above with respect to a block can be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, TX MIMO processor 266, or another processor can be performed by or under the control of controller / processor 280.

[0072] Figure 3 This is a diagram illustrating one or more examples 300 of PDCCH parameters used for multiple cell groups. (Example 300) Figure 3 As shown, Example 300 may include UE 120 (such as...) Figure 1 UE 120a to 120e or as depicted and described in Figure 2 The UE 120 depicted and described in the text and the base station 110 (such as...) Figure 1 BS 110a to 110d or as described in the text Figure 2Communication between UE 120 and base station 110 (as depicted in the diagram). UE 120 and base station 110 may be included in a wireless network (such as wireless network 100). In some aspects, UE 120 may be able to be deployed in an NR dual connectivity configuration or an NR multi-connectivity configuration. For example, UE 120 may be configured with multiple cell groups, such as one or more primary cell groups and one or more secondary cell groups. Each cell group may include one or more cells, such as one or more primary cells and one or more secondary cells. In some aspects, the cells within each cell group configured for UE 120 may be time-synchronized within each cell group, or time-asynchronous across two or more cell groups, or a combination thereof.

[0073] like Figure 3 As shown, and via reference numeral 302, UE 120 can identify the PDCCH blind decoding capability value and the PDCCH control channel element capability value of UE 120 and send an indication thereof to base station 110. In some aspects, UE 120 can send the indication at least in part based on identifying the PDCCH blind decoding capability value and the PDCCH control channel element capability value. In some aspects, UE 120 can identify the PDCCH blind decoding capability value and the PDCCH control channel element value at least in part based on the capabilities of UE 120. The PDCCH blind decoding capability value can indicate the number of blind decoding operations that UE 120 can perform on multiple consecutive PDCCH symbols within a PDCCH time slot or across a cell group configured for UE 120. The PDCCH control channel element capability value can indicate the number of control channel elements that UE 120 can process on multiple consecutive PDCCH symbols within a PDCCH time slot or across a cell group configured for UE 120.

[0074] UE 120 may send this indication in one or more uplink communications, such as one or more uplink control information (UCI) communications, one or more radio resource control (RRC) communications, one or more media access control (MAC) control element (MAC-CE) communications, or other types of uplink communications.

[0075] In some aspects, if UE 120 is capable of communicating over multiple frequency ranges (such as the 5G FR1 frequency range, the 5G FR2 frequency range, and other frequency ranges), UE 120 can transmit a single PDCCH blind decoding capability value and a single PDCCH control channel element capability value across all frequency ranges or subsets of frequency ranges in each cell group. In other aspects, if UE 120 is configured with more than two cell groups and is capable of communicating over multiple frequency ranges, UE 120 can transmit a separate PDCCH blind decoding capability value and a separate PDCCH control channel element capability value for each frequency range within each cell group. In this case, the separate PDCCH blind decoding capability value can be the same for all frequency ranges, or a subset of the separate PDCCH blind decoding capability values ​​can be different. Similarly, the separate PDCCH control channel element capability value can be the same for all frequency ranges, or a subset of the separate PDCCH control channel element capability values ​​can be different. In some respects, if UE 120 is configured with more than two cell groups and is capable of communicating over multiple frequency ranges, UE 120 may send individual PDCCH blind decoding capability values ​​for each frequency range associated with the downlink serving cell included in each cell group configured for UE 120, wherein the individual PDCCH blind decoding capability values ​​are the same PDCCH blind decoding capability values ​​used across all frequency ranges configured for the cell group.

[0076] like Figure 3 As further shown and by reference numeral 304, UE 120, base station 110, or a combination thereof, can determine PDCCH parameters for the PDCCH processed by UE 120. Determining PDCCH parameters may include selecting PDCCH parameters. PDCCH parameters may include PDCCH blind decoding restrictions and PDCCH control channel element restrictions. In some aspects, PDCCH parameters may include other PDCCH processing parameters.

[0077] In some aspects, the PDCCH blind decoding limit can identify the number of blind decodings that UE 120 needs to perform on multiple consecutive PDCCH symbols within a PDCCH slot or across a cell group configured for UE 120. In some aspects, the PDCCH blind decoding limit can be a combined PDCCH blind decoding limit for UE 120, and UE 120 (or base station 110, or both UE 120 and base station 110) can determine a separate PDCCH blind decoding limit for each cell group configured for UE 120, associated with or at least partially based on the combined PDCCH blind decoding limit. Determining the separate PDCCH blind decoding limit can include selecting the respective PDCCH blind decoding limit.

[0078] In some aspects, the PDCCH control channel element limit can identify the number of control channel elements that UE 120 needs to process in a PDCCH slot or across multiple consecutive PDCCH symbols configured for UE 120. In some aspects, the PDCCH control channel element limit can be a combined PDCCH control channel element limit for UE 120, and UE 120 (or base station 110, or both UE 120 and base station 110) can determine its respective PDCCH control channel element limit for each cell group configured for UE 120 in association with or at least in part based on the combined PDCCH control channel element limit. Determining the respective PDCCH control channel element limit can include selecting the respective PDCCH control channel element limit.

[0079] UE 120 (or base station 110, or both UE 120 and base station 110) may determine (which may include selection) PDCCH blind decoding restrictions and PDCCH control channel element restrictions associated with a cell group, or at least partially based on a cell group. In some aspects, UE 120 (or base station 110, or both UE 120 and base station 110) may determine (which may include selection) PDCCH blind decoding restrictions and PDCCH control channel element restrictions associated with UE 120's PDCCH blind decoding capability value and UE 120's PDCCH control channel element capability value, as well as other factors or parameters or combinations thereof, or at least partially based on UE 120's PDCCH blind decoding capability value and UE 120's PDCCH control channel element capability value, as well as other factors or parameters or combinations thereof.

[0080] For example, in some aspects, UE 120 may determine (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits associated with the total number of cell groups configured for UE 120, or at least in part based on that total number. In this case, UE 120 (or base station 110, or both UE 120 and base station 110) may determine (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits for N cell groups configured for UE 120, regardless of whether a particular cell group is active or deactivated at the time of determination. As another example, in some aspects, UE 120 determines (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits associated with the number of M cell groups configured for UE 120, or at least in part based on that number, which are active (e.g., active at the time of determination). In this case, the number of M cell groups can be less than or equal to the number of N cell groups configured for UE 120.

[0081] In some aspects, base station 110 or another entity in the wireless network may configure UE 120 to determine (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits (e.g., for the total number of cell groups configured for UE 120 or for the number of active cell groups). In some aspects, UE 120 (or base station 110, or both UE 120 and base station 110) may determine (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits for the total number of cell groups configured for UE 120 or the number of active cell groups associated with or at least partially based on the capabilities of UE 120. This determination or selection may be associated with or at least partially based on the ability to quickly and repeatedly select or determine the number of active cell groups while minimizing latency in the determination. In this scenario, a lower-capacity UE 120 can determine (which may include selection) a simplified solution requiring less processing and memory resources by limiting the PDCCH blind decoding and PDCCH control channel element limits for the total number of cell groups configured for the UE 120, while a higher-capacity UE 120 can determine (which may include selection) a more adaptive solution for the UE 120's service mode by limiting the PDCCH blind decoding and PDCCH control channel element limits for the number of active cell groups.

[0082] In some aspects, UE 120 determines (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits for the total number of cell groups configured for UE 120 or for the number of active cell groups associated with or at least partially based on the total number of cell groups configured for UE 120. For example, UE 120 may determine (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits for the number of active cell groups based at least partially on the determination that the total number of cell groups does not meet a threshold number of cell groups (e.g., three or more cell groups). UE 120 may determine (which may include selection) PDCCH blind decoding limits and PDCCH control channel element limits for the total number of cell groups configured for UE 120 based at least partially on the determination that the total number of cell groups does not meet a threshold number of cell groups (e.g., less than three cell groups).

[0083] In some aspects, UE 120 may determine (which may include selection) PDCCH parameters based at least in part on a request for indication of PDCCH parameters received from (e.g., from base station 110). In some aspects, UE 120 (or base station 110, or both UE 120 and base station 110) may determine (which may include selection) PDCCH parameters in various scenarios (such as in soft handover or connect-before-disconnect handover) where UE 120 is simultaneously communicating with one or more source cell groups and one or more target cell groups.

[0084] In some aspects, base station 110 may send an indication of PDCCH configuration to UE 120. In some aspects, PDCCH configuration may be associated with or at least partially based on PDCCH blind decoding limits and PDCCH control channel element limits. In some aspects, PDCCH configuration may configure the number of PDCCH candidates for UE 120 such that the number of blind decodes or control channel elements for UE 120 exceeds or is not supported by PDCCH blind decoding limits and PDCCH control channel element limits. In some cases, this may be referred to as overbooking. In some aspects, such as when configuring more than two cell groups for UE 120, base station 110 may be allowed to configure overbooking in the various cell groups configured for the UE. For example, base station 110 may be allowed to overbook all cell groups configured for UE 120. In this scenario, base station 110 is allowed to configure UE 120 to perform a certain number of blind decoding operations in cells within any cell group, such that the number of blind decoding operations in the cell group exceeds the PDCCH blind decoding limit of the cell group or is not supported by the PDCCH blind decoding limit of the cell group. Furthermore, base station 110 is allowed to configure UE 120 to process a certain number of control channel elements in cells within any cell group, such that the number of control channel elements in the cell group exceeds the PDCCH control channel element limit of the cell group or is not supported by the PDCCH control channel element limit of the cell group.

[0085] As another example, base station 110 may be allowed to over-prescribe primary cell groups configured for UE 120. In this case, base station 110 is allowed to configure UE 120 to perform a certain number of blind decodings in the cells of the primary cell group, such that the number of blind decodings in the primary cell group exceeds the PDCCH blind decoding limit of the primary cell group or is not supported by the PDCCH blind decoding limit of the primary cell group. Furthermore, base station 110 is allowed to configure UE 120 to process a certain number of control channel elements in the cells of the primary cell group, such that the number of control channel elements in the primary cell group exceeds the PDCCH control channel element limit of the primary cell group or is not supported by the PDCCH control channel element limit of the primary cell group.

[0086] As another example, base station 110 may be allowed to indicate to UE 120 which cell groups will be oversubscribed. In this case, base station 110 may be allowed to configure UE 120 to perform a certain number of blind decodings in the cells of the specified cell group, such that the number of blind decodings in the specified cell group exceeds the PDCCH blind decoding limit of the specified cell group or is not supported by the PDCCH blind decoding limit of the specified cell group. Furthermore, base station 110 may be allowed to configure UE 120 to process a certain number of control channel elements in the cells of the specified cell group, such that the number of control channel elements in the specified cell group exceeds the PDCCH control channel element limit of the specified cell group or is not supported by the PDCCH control channel element limit of the specified cell group.

[0087] In some respects, base station 110 is not permitted to over-prescribe any cell group configured for UE 120. Specifically, base station 110 is not permitted to configure UE 120 to perform a certain number of blind decoding operations in any cell group, such that the number of blind decoding operations in the cell group exceeds the PDCCH blind decoding limit of the cell group or is not supported by the PDCCH blind decoding limit of the cell group. Furthermore, base station 110 is not permitted to configure UE 120 to process a certain number of control channel elements in any cell group, such that the number of control channel elements in the cell group exceeds the PDCCH control channel element limit of the cell group or is not supported by the PDCCH control channel element limit of the cell group.

[0088] In some aspects, base station 110 may be allowed to over-subscribe to specific cells within a cell group, such as primary cells only, secondary cells only, or a combination of primary and secondary cells. In this case, base station 110 may configure UE 120 to perform a certain number of blind decodings in specific cells of the cell group, such that the number of blind decodings in the cell group exceeds the PDCCH blind decoding limit for specific cells of the cell group or is not supported by the PDCCH blind decoding limit for specific cells of the cell group. Furthermore, base station 110 may be allowed to configure UE 120 to process a certain number of control channel elements in specific cells of the cell group, such that the number of control channel elements in specific cells of the cell group exceeds the PDCCH control channel element limit for specific cells of the cell group or is not supported by the PDCCH control channel element limit for specific cells of the cell group.

[0089] Figure 4 This is a diagram illustrating one or more example 400s of PDCCH parameters used for multiple cell groups. (Example 400) Figure 4 As shown, Example 400 may include UE 120 (such as...) Figure 1 UE 120a to 120e or as depicted and described in Figure 2 The UE 120 described and illustrated in the text and the base station 110 (such as...) Figure 1BS 110a to 110d or as described in the text Figure 2 Communication between UE 120 and base station 110 (as depicted in the diagram). UE 120 and base station 110 can be included in a wireless network (such as wireless network 100). In some aspects, UE 120 may be able to be deployed in an NR multi-connectivity configuration. For example, UE 120 may be configured with two or more cell groups, such as one or more primary cell groups and multiple secondary cell groups. Each cell group may include one or more cells, such as one or more primary cells and one or more secondary cells. In some aspects, the cells within each cell group configured for UE 120 may be time-synchronized within each cell group, or time-asynchronous across two or more cell groups, or a combination thereof.

[0090] like Figure 4 As shown and via reference numeral 402, UE 120 can target each cell group CG in cell group 1 to cell group L configured for UE 120. i Determine the number of cells (or reference number) N for PDCCH blind detection. i Determining the cell reference number (or reference quantity) may include selecting and determining the cell reference number (or reference quantity). The cell reference number for a cell group may be the number of cells that the UE 120 uses to determine or select the PDCCH blind detection limit, the PDCCH control channel element limit, or a combination thereof for the cell group. In some respects, the cell reference number may be the same for each cell group configured for the UE 120, or it may be different for at least one subset of the cell groups.

[0091] In some aspects, UE 120 can determine the cell reference number of a cell group by selecting a cell reference number from a range of cell numbers configured for UE 120 (e.g., a range of [1,...,15] cells). In some aspects, UE 120 (or base station 110) can determine or select the cell reference number for each cell group such that Equation 1 is satisfied:

[0092]

[0093] Where N LY is the number of cell groups configured for UE 120 (or the number of active cell groups out of the total number of cell groups configured for UE 120) and Y is the PDCCH blind decoding capability value of UE 120 (e.g., the combined PDCCH blind decoding capability value of UE 120 if reported by UE 120, such as pdcch-BlindDetectionCA) or the number of downlink serving cells that UE 120 can support across all cell groups configured for UE 120. In this case, UE 120 can select or determine the number of cell references for each cell group such that the sum of the number of cell references for each cell group is less than or equal to the combined PDCCH blind decoding capability value, or the number of downlink serving cells configured across all cell groups configured for UE 120. In some aspects, UE 120 can use the above combination Figure 3 The description refers to one or more techniques, as well as other techniques, for selecting or determining the combined PDCCH blind decoding capability value.

[0094] like Figure 4 As further shown and indicated by reference numeral 404, UE 120 can determine PDCCH blind decoding limits and PDCCH control channel element limits configured for each cell group, which are associated with or at least partially based on a number of cell references selected or determined for each cell group. Determining the PDCCH blind decoding limits and PDCCH control channel element limits may include selecting the PDCCH blind decoding limits and PDCCH control channel element limits. In this case, UE 120 can select or determine the PDCCH blind decoding limits and PDCCH control channel element limits for a cell group, which are associated with or at least partially based on a number of cell references selected or determined for that cell group. In some respects, UE 120 may select or determine PDCCH blind decoding limits and PDCCH control channel element limits configured for each cell group of UE 120, the PDCCH blind decoding limits and PDCCH control channel element limits being associated with or at least partially based on the number of cell references selected or determined for each cell group.

[0095] like Figure 4 As shown and via reference numeral 406, UE 120 can select or determine each cell group CG among cell group 1 to cell group L configured for UE 120. i Reference number of communities N i The upper limit N i,capThe upper limit for a cell group can be the maximum number of cells that the UE120 can support, serving as a reference number for the cell group. In some respects, the upper limit can be the same for each cell group configured for the UE120, or it can be different for at least one subset of the cell groups.

[0096] In some aspects, UE 120 can select or determine the upper limit of the reference number of cell groups by choosing an upper limit from the upper limit range of [1,...,X-1] cells configured for UE 120. If reported by UE 120, X may correspond to the PDCCH blind decoding capability value of UE 120 (e.g., corresponding to a combined PDCCH blind decoding capability value, such as pdcch-BlindDetectionCA, reported by UE 120 for carrier aggregation with more than four configured cells), or if UE 120 does not select, determine, or report a combined PDCCH blind decoding capability value to base station 110, X may be a configurable or specified value. In some aspects, UE 120 can select or determine the upper limit of the cell reference number for each cell group such that Equation 2 is satisfied:

[0097]

[0098] Where N L Z is the number of cell groups configured for UE 120 (or the number of active cell groups out of the total number of cell groups configured for UE 120), and Z is the combined PDCCH blind decoding capability value of UE 120 or the number of downlink serving cells that UE 120 can support across all cell groups configured for UE 120. In this case, UE 120 can select or determine an upper limit for the number of cell references for each cell group, such that the sum of the upper limits for the number of cell references for each cell group is greater than or equal to the combined PDCCH blind decoding capability value, or the number of downlink serving cells that UE 120 can support across all cell groups configured for UE 120.

[0099] like Figure 4 As further shown and by reference numeral 408, UE 120 can send an indication to base station 110 of an upper limit for the number of cell references configured for each cell group for UE 120. In some aspects, UE 120 can send the indication of the upper limit for the number of cell references for each cell group in association with or at least in part based on the selection or determination of an upper limit. In some aspects, combined PDCCH blind decoding restrictions and combined PDCCH control channel element restrictions can be used in various scenarios (such as in soft handover or connect-before-disconnect handover) where UE 120 simultaneously communicates with one or more source cell groups and one or more target cell groups.
