[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 706,287, filed August 7, 2020, entitled “Auxiliary Component Carrier Dropping for Power Margin”, and U.S. Non-Provisional Patent Application No. 17 / 444,495, filed August 5, 2021, entitled “Auxiliary Component Carrier Dropping for Power Margin”, which are hereby expressly incorporated by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communication, and to techniques and apparatus for dropping secondary component carriers for power margin. 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 may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power). 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 set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs may communicate with the BS via downlink and uplink. "Downlink" or "forward link" refers to the communication link from the BS to the UE, and "uplink" or "reverse link" refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, or 5G Node B.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, or even global level. NR, also known as 5G, is a set of enhancements to the LTE mobile standard released by 3GPP. NR aims to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards. These open standards use Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL), and support beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. However, with the continued growth in demand for mobile broadband access, further improvements to LTE, NR, and other radio access technologies are needed. Summary of the Invention

[0011] 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 the UE, cause the UE to: transmit communication on the PCC and SCC, and suppress transmission on the SCC based at least in part on the error rate of transmission on the SCC and the amount of transmission power margin of the UE.

[0012] 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 base station, cause the base station to: schedule uplink communication for the UE on the PCC and SCC, and adjust the scheduling of uplink communication of the UE on the SCC based at least in part on the error rate of transmissions on the SCC and the amount of transmission power margin of the UE.

[0013] In some aspects, an apparatus for wireless communication includes: an apparatus module for transmitting communication on a PCC and an SCC, and an apparatus module for suppressing transmission on the SCC based at least in part on the error rate of transmission on the SCC and the amount of transmission power margin of the apparatus.

[0014] In some aspects, an apparatus for wireless communication includes: an apparatus module for scheduling uplink communication for a UE on a PCC and a SCC, and an apparatus module for adjusting the scheduling of uplink communication of the UE on the SCC based at least in part on the error rate of transmission on the SCC and the amount of transmission power margin of the UE.

[0027] The various aspects of this disclosure will be described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided to make this disclosure thorough and complete, and to fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover an apparatus or method practiced using a structure, function, or structure and function other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0028] Several aspects of a telecommunications system will now be described with reference to various devices and technologies. These devices and technologies will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints on the overall system.

[0029] It should be noted that 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).

[0030] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Among other examples, the wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network. The wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, or Transmit / Receive Point (TRP). Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0031] A Base Station (BS) can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access for UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access for UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a home) and can allow restricted access for UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macrocell can be referred to as a macro BS. A BS for a picocell can be referred to as a pico BS. A BS for a femtocell can be referred to as a femtocell BS or a home BS. Figure 1 In the example shown, BS 110a can be a macro BS of macro cell 102a, BS 110b can be a pico BS of pico cell 102b, and BS 110c can be a femto BS of femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”, “TRP”, “AP”, “Node B”, “5G NB”, and “cell” are used interchangeably in this document.

[0032] In some respects, the cell is not necessarily stationary, and the geographical area of ​​the cell can move depending on the location of the mobile BS. In some respects, BSs can interconnect with each other and / or interconnect to one or more other BSs 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).

[0033] The wireless network 100 may also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, or relay.

[0034] Wireless network 100 can be a heterogeneous network, comprising different types of base stations (BSs), such as macro BSs, pico BSs, femto BSs, and / or relay BSs. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0035] Network controller 130 can be coupled to a collection of BSs and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0036] UEs 120 (e.g., 120a, 120b, 120c) may be distributed across the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0037] 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, instruments, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node can provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] Generally, 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 radio technology and / or air interface. A frequency can also be referred to as a carrier and / or channel. 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.

[0039] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as a medium for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0040] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band with a first frequency range (FR1) from 410 MHz to 7.125 GHz, and / or may communicate using an operating band with a second frequency range (FR2) from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the “sub-6 GHz” band. Similarly, FR2 is generally referred to as the “millimeter wave” (mmWave) band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU). Therefore, unless specifically stated otherwise, it should be understood that the terms “sub-6 GHz”, etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or intermediate frequency (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that the terms “millimeter wave” and the like, if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0041] As mentioned above, Figure 1 This is provided as an example. Other examples may differ from those provided. Figure 1 As described.

[0042] Figure 2 This is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0043] 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 (e.g., encode and modulate) the data for that UE based at least in part on the selected MCS(s) for that UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, upper-layer signaling), 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), 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) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if 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) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively.

[0044] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain a received symbol. 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 (e.g., demodulate and decode) the detected symbols, provide the decoded data of UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Received Reference Signal Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Signal Quality (RSRQ), and / or CQI, etc. In some respects, one or more components of the UE 120 may be included in the housing 284.

[0045] 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.

[0046] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included in one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0047] 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 reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmitting processor 264 can be pre-encoded by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator of UE 120 (e.g., MOD / DEMOD 254) can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The processor (e.g., controller / processor 280) and memory 282 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figures 3-8 (As described).

[0048] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 for scheduling UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes transceivers. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The processor (e.g., controller / processor 240) and memory 242 may be used with the transceiver to perform aspects of any of the methods described herein (e.g., as referenced). Figures 3-8 (As described).

[0049] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component(s) may perform one or more techniques associated with discarding secondary component carriers (SCCs) for power margin, 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(s) can perform or direct, for example Figure 5 Process 500 Figure 6 The operation of process 600 and / or other processes described herein. Memory 242 and 282 may store data and program code of base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when one or more instructions are executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, transformation, and / or interpretation), they may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 5 Process 500 Figure 6 The operation of process 600 and / or other processes described herein. In some aspects, the execution instructions may include run instructions, translation instructions, compilation instructions, and / or interpretation instructions, etc.

[0050] In some aspects, UE 120 may include means modules for transmitting communication on the primary component carrier (PCC) and the SCC, and / or means modules for suppressing transmission on the SCC based at least in part on the error rate of transmission on the SCC and the amount of the UE's transmission power margin. In some aspects, these means modules may include combinations of Figure 2 One or more components of the described UE 120, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256 and / or receive processor 258.

[0051] In some aspects, base station 110 may include means modules for scheduling uplink communication for the UE on the PCC and SCC, and / or means modules for adjusting the scheduling of the UE's uplink communication on the SCC based at least in part on the error rate of transmissions on the SCC and the amount of the UE's transmission power margin. In some aspects, these means modules may include combinations of Figure 2One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232 and / or antenna 234.

[0052] Although Figure 2 The blocks are shown as different components, but the functions described above for each block can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described for the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0053] As mentioned above, Figure 2 This is provided as an example. Other examples may differ from those provided. Figure 2 As described.

[0054] Figure 3 This is a diagram illustrating example 300 of carrier aggregation according to this disclosure.

[0055] Carrier aggregation is a technique that enables two or more component carriers (CCs, sometimes called carriers) to be combined (e.g., combined into a single channel) for use by a single UE 120 to enhance data capacity. As shown, carriers can be combined in the same or different frequency bands. Additionally or alternatively, contiguous or non-contiguous carriers can be combined. Base station 110 can configure carrier aggregation for UE 120, such as in Radio Resource Control (RRC) messages and / or Downlink Control Information (DCI).

[0056] As shown by reference numeral 305, in some aspects, carrier aggregation can be configured as an in-band adjacency mode, wherein the aggregated carriers are adjacent to each other and in the same frequency band. As shown by reference numeral 310, in some aspects, carrier aggregation can be configured as an in-band non-adjacency mode, wherein the aggregated carriers are not adjacent to each other and in the same frequency band. As shown by reference numeral 315, in some aspects, carrier aggregation can be configured as an inter-band non-adjacency mode, wherein the aggregated carriers are not adjacent to each other and in different frequency bands.

[0057] In carrier aggregation, UE 120 can be configured with a PCC and one or more SCCs. In some aspects, the PCC can carry control information (e.g., DCI, scheduling information, etc.) for scheduling data communications on one or more SCCs, which can be referred to as cross-carrier scheduling. In some aspects, the carrier (e.g., PCC or SCC) can carry control information for scheduling data communications on the carrier, which can be referred to as self-carrier scheduling or carrier self-scheduling.

[0058] As mentioned above, Figure 3 This is provided as an example. Other examples may differ from those provided. Figure 3 As described.

[0059] The network can schedule grants for uplink carrier aggregation (or dual connectivity) for the UE. However, network parameters may not be optimized for grants. As a result, communication may degrade, and the UE may waste power. For example, the network may consider uplink metrics for decoding the Physical Uplink Shared Channel (PUSCH) on multiple carriers, but not how much power is available for the UE to transmit on the SCC (power margin). For example, the UE's power margin index might be 33, indicating that no power is available for the UE to transmit on the SCC, but the network may still allocate grants on the SCC. Therefore, grants for the SCC result in a high block error rate (BLER). If the BLER on the SCC is high and Hybrid Automatic Repeat Request (HARQ) cannot resolve the BLER, retransmissions are required. These retransmissions may increase latency at higher layers and lead to a decrease in throughput. This results in wasted power, processing resources, and signaling resources for both the UE and the network.

[0060] Based on the various aspects described herein, when a UE determines that a SCC is failing (e.g., high BLER) and there is insufficient power margin for the SCC (e.g., the PCC is consuming too much power), the UE can discard the SCC. For example, the UE can suppress transmissions on the SCC (e.g., ignore uplink grants for the SCC) and / or apply discontinuous transmissions on the PUSCH until the power margin improves. In some aspects, the UE can wait for specific transmission time intervals, store data for calculating BLER, and / or establish a pattern with power margin reporting. If, during a specific time period, the BLER is above a specific percentage (e.g., a BLER threshold), the power margin is below a specific level, and / or the path loss is above a specific level (which can be reflected in the error rate), the UE can discard the SCC. In some aspects, before discarding the SCC, the UE can wait for the HARQ process to be exhausted, which can include silencing or suppressing transmissions on the PUSCH using the SCC. As a result, the UE and network will save power, improve latency, and save time, power, processing resources, and signaling resources that would otherwise be consumed by retransmissions. The UE also reduces regulated, unnecessary radio power emissions, and the network can improve bandwidth efficiency. Furthermore, on average, the UE will have more power available for PCC, increasing overall throughput.

[0061] Figures 4A-4B This is a diagram illustrating example 400 of discarding SCC for power margin according to this disclosure. Figures 4A-4B As shown, Example 400 includes a base station (BS) 410 (e.g., Figure 1 and Figure 2 The BS 110 and UE 420 described in the text (e.g., Figure 1 and Figure 2 Communication between BS 410 and UE 420 (as depicted in the diagram). In some aspects, BS 410 and UE 420 may be included in a wireless network, such as wireless network 100. BS 410 and UE 420 may communicate using carrier aggregation, wherein BS 410 and UE 420 communicate on a PCC that may include uplink and downlink, and an SCC that may include uplink and downlink. Although Figures 4A-4B Carrier aggregation (e.g., NR PCC / SCC) is shown, but in some respects, the UE 420 can use dual connectivity to communicate with another BS. Carrier aggregation can be used for transmissions in millimeter wave (FR2) and / or FR1.

[0062] BS 410 can schedule uplink communication for UE 420 on the PCC and SCC, as shown by reference numeral 440. Therefore, UE 420 can transmit communication on the PCC and SCC, as shown by corresponding reference numerals 445 and 450. UE 420 can also receive communication on the PCC and SCC, but the transmission power requirements are higher; therefore, for illustrative purposes, Example 400 illustrates the transmission of UE 420.

[0063] UE 420 may experience a specific error rate on SCC, a specific amount of path loss, and / or a specific amount of power margin reduction. The power margin may be too low (e.g., falling by a threshold amount or reaching a threshold amount), so UE 420 may determine to drop the SCC. The SCC may also have an excessively high error rate (e.g., increasing by a threshold amount or reaching a threshold amount). Note that the amount of increase or decrease can be calculated relative to an absolute threshold amount.

[0064] like Figure 4BAs shown in Figure 455, UE 420 can suppress transmissions on the SCC, at least in part, based on the amount of error rate and power margin. UE 420 does not need to disable signaling hardware. Instead, UE 420 can ignore uplink grants from BS 410 (transmitting without regard to the grant). Resources can be moved to another link, which could be the PCC or another SCC requiring less power. The Media Access Control (MAC) layer can avoid building transport blocks on the SCC and can automatically schedule resources on the PCC. In some respects, UE 420 can transmit acknowledgments of the higher-layer SCC payload as part of the PCC payload. Alternatively, in some respects, UE 420 can apply a discontinuous transmission mode on the PUSCH, causing uplink data to be transmitted on the SCC in specific time periods.

[0065] Although Example 400 describes a scenario with carrier aggregation, combined with Figures 4A-4B The described operation can be extended to other dual-carrier scenarios, including dual connectivity (e.g., NR dual connectivity). Dual connectivity operation can be based at least in part on the radio conditions and / or power requirements of the radio access technology involved.

[0066] Conditions at the PCC or SCC may change, and / or the UE 420 may determine that more power margin is available for one or more reasons. In some respects, the UE 420 may restart uplink transmission on the SCC based at least in part on one or more factors. For example, the UE 420 may restart uplink transmission on the SCC (or another SCC) after a specific amount of time. The UE 420 may restart transmission on the SCC after the power margin has increased by a specific amount, after path loss conditions have passed, after the MCS has decreased by a specific amount (or decreased to a specific level), after resource block (RB) allocation has decreased by a specific amount, or a combination of these conditions.

[0067] Alternatively or additionally, BS 410 can resolve SCC failures due to power margin issues at UE 420. In some aspects, BS 410 can adjust the scheduling authorization for uplink communications to UE 420 based at least in part on the determination that UE 420 has dropped SCC by ignoring uplink authorization or by applying discontinuous transmissions on the PUSCH. BS 410 can also receive additional indications or signaling from UE 420 indicating that UE 420 has dropped transmissions on SCC. BS 410 can adjust the scheduling authorization by temporarily reducing or eliminating uplink authorization to UE 420.

[0068] In some respects, BS 410 can adjust scheduling authority based at least in part on the SCC error rate (e.g., BLER) and power headroom reports from UE 420. For example, BS 410 can adjust scheduling authority based at least in part on UE 420's power headroom decreasing by a specific amount to a power headroom threshold or becoming negative, path loss reaching a specific amount, HARQ exhaustion without resolving the issue, and / or BLER reaching a specific level. UE 420 can provide and receive power headroom reports.

[0069] In some respects, BS 410 can restart the scheduling authorization for uplink transmission on the SCC based at least in part on one or more of the factors described above for restarting uplink transmission on the SCC for UE 420. BS 410 can receive an indication that UE 420 has restarted transmission on the SCC by receiving uplink communication based on previously ignored scheduling authorization. BS 410 can also determine that discontinuous transmission has stopped, or receive some other indication or signaling from UE 420 that transmission on the SCC has restarted. As a result of dropping and restarting uplink transmission on the SCC, BS 410 and / or UE 420 can dynamically manage uplink transmission based on UE 420's power margin, saving time, power, processing resources, and signaling resources. Communication is also improved.
