[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 976,106, filed on February 13, 2020, entitled “DYNAMIC POWER CONTROL FOR PRIORITY BASED TRAFFIC,” and U.S. Non-Provisional Patent Application No. 17 / 165,576, filed on February 2, 2021, entitled “DYNAMIC POWER CONTROL FOR PRIORITYBASED TRAFFIC,” which are hereby expressly incorporated herein by reference.

[0003] Public domain

[0004] Aspects of the present disclosure generally relate to wireless communications and techniques and devices for dynamic power control for priority-based traffic.

[0005] background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may 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 / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless network may include several base stations (BSs) that can support communications for several user equipments (UEs). The UE may communicate with the BS via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, while the 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, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at city, country, region, and even global levels. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies are still useful.

[0009] Overview

[0010] In some aspects, a method of wireless communication performed by a user equipment (UE) may include: determining a deadline before a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level; determining whether to perform a second uplink transmission associated with a main cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjusting a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level.

[0011] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: determine a deadline before a first uplink transmission associated with an SCG, wherein the first uplink transmission is associated with a first priority level; determine whether to perform a second uplink transmission associated with an MCG, wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjust a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to: determine a deadline before a first uplink transmission associated with an SCG, wherein the first uplink transmission is associated with a first priority level; determine whether to perform a second uplink transmission associated with an MCG, wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjust a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level.

[0013] In some aspects, an apparatus for wireless communications may include: a device for determining a deadline prior to a first uplink transmission associated with an SCG, wherein the first uplink transmission is associated with a first priority level; a device for determining whether to perform a second uplink transmission associated with an MCG, wherein the second uplink transmission is initiated after the deadline and wherein the second uplink transmission is associated with a second priority level; and a device for adjusting a transmit power of the first uplink transmission based at least in part on at least one of: a device for determining whether to perform the second uplink transmission, or the first priority level and the second priority level.

[0014] Aspects generally include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication devices, and / or processing systems as substantially described herein with reference to and as illustrated in the accompanying figures and specification.

[0023] Detailed Description

[0024] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is independently implemented or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0025] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0026] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).

[0027] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) 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, a B node, a gNB, a 5G B node (NB), an access point, a transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0028] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “B node,” “5G NB,” and “cell” may be used interchangeably herein.”

[0029] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or 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.

[0030] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0031] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0032] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0033] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), 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, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, 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, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0034] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some aspects, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0035] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0036] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. 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 described elsewhere herein as being performed by base station 110.

[0037] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network can communicate using an operating frequency band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2) that can span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise specifically stated, it should be understood that if used herein, the term "sub-6 GHz" or the like can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that if used herein, the term "millimeter wave" or the like can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0038] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0039] Figure 2is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0040] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also 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 signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0041] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284 .

[0042] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0043] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. 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 transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).

[0044] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, where applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the 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 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, for example, as described with reference to Figure 3-Figure 7 As described.

[0045] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. 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 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, for example, as described with reference to Figure 3-Figure 7 As described.

[0046] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the base station 110 may perform one or more techniques associated with dynamic power control for priority-based traffic, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 7 The operations of process 700 and / or other processes as described herein. Memories 242 and 282 may store data and program codes for 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, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 7 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other aspects.

[0047] In some aspects, UE 120 may include: means for determining a deadline before a first uplink transmission associated with an SCG, wherein the first uplink transmission is associated with a first priority level; means for determining whether to perform a second uplink transmission associated with an MCG, wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and means for adjusting a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level; and so on. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0048] although Figure 2The blocks in the 200 and 210 are illustrated as different components, but the functions described above with respect to these blocks may be implemented with a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0049] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0050] In New Radio - Dual Connectivity (NR-DC) power sharing, transmissions to a primary cell group (MCG) may be prioritized over transmissions to a secondary cell group (SCG). If transmissions to the MCG and SCG overlap in time, the UE may reduce the transmit power to the SCG. In order to provide sufficient time to adjust the SCG transmit power, the UE may determine a deadline by which the overlapping transmissions must be detected. For example, downlink control information (DCI) (or another appropriate physical downlink control channel (PDCCH) message) may schedule an uplink transmission to the SCG at time T0 (such as in a physical uplink shared channel (PUSCH)). By using an offset time (such as T_offset), the UE may determine a deadline of T0-T_offset. If the UE receives a DCI scheduling an uplink transmission to the MCG that overlaps in time with a scheduled SCG uplink transmission before the deadline, the UE may reduce the transmit power of the SCG uplink transmission. If the UE receives a DCI after the deadline that schedules an uplink transmission to the MCG that overlaps in time with a scheduled SCG uplink transmission, the UE may not reduce the SCG uplink transmit power. This is because the specifications provided by the relevant communication protocols (such as the 5G / NR protocols) ensure that the UE will not receive a DCI from the network after the deadline that schedules an MCG uplink transmission that overlaps in time with a scheduled SCG uplink transmission.

[0051] In some cases, the UE may determine to perform an uplink transmission on the MCG without receiving a DCI for the uplink transmission. For example, an indication of uplink data associated with a semi-static uplink transmission may arrive after a deadline (e.g., T0-T_offset). When the UE is not configured with dynamic power sharing (and therefore does not use a deadline), if there are configured grant (CG) PUSCH resources on the MCG, the UE may utilize the CG PUSC regardless of when the uplink data arrives from higher layers. However, when the UE is configured with NR-DC dynamic power sharing, if the MCG PUSCH overlaps with the SCG PUSCH after the deadline at T0, it may be difficult to allocate dynamic grant PUSCH resources on the MCG that overlaps with the SCG PUSCH. Thus, in this case, the CG PUSCH resources may be used to transmit uplink data (because the dynamic grant (DG) PUSCH is not available when the indication associated with the uplink data is received after the deadline). The UE may determine whether semi-static uplink transmission is to be performed based at least in part on the deadline and based at least in part on whether a skip or cancel indication is received before the deadline, which may be combined with Figure 3 Let's describe it in more detail.

[0052] Some communications or resource allocations may be associated with a priority level. For example, 3GPP Release 16 Ultra-Reliable Low Latency Communications (URLLC) introduces a 1-bit priority indication in the DL DCI and UL DCI. If multiple transmissions associated with different priority indices overlap, the UE may discard the transmission with the lower priority index. The UE may first resolve overlapping PUSCH or Physical Uplink Control Channel (PUCCH) transmissions with the same priority index across UL carriers (e.g., for each UL carrier, the UE may resolve overlapping communications within that carrier). If two overlapping UL transmissions have different priority levels (generally referred to as high priority and low priority), the UE may apply the following rules:

[0053] PUCCH with high priority vs. PUSCH / PUCCH with priority: discard PUSCH / PUCCH with low priority

[0054] PUSCH with high priority vs. PUCCH with priority: discard PUCCH with low priority

[0055] Dynamically Granted (DG) PUSCH with high priority vs. Configured Grant (CG) PUSCH with low priority: discard CG-PUSCH with low priority

[0056] CG-PUSCH with high priority versus DG-PUSCH with low priority: DG-PUSCH with low priority is discarded

[0057] CG-PUSCH with high priority versus CG-PUSCH with low priority: discard CG-PUSCH with low priority

[0058] Thus, the UE may resolve overlapping transmissions associated with different priority levels.

[0059] In some aspects, the UE may determine after a deadline that semi-static uplink transmission may be performed. In addition, the semi-static uplink transmission may be associated with a priority level. In such a situation, there may be ambiguity as to how the semi-static uplink transmission and the overlapping uplink transmission on the SCG should be dynamically power shared. For example, the transmit power of the overlapping uplink transmission on the SCG may be affected by whether the semi-static uplink transmission will be performed, and after the deadline, there is a certain uncertainty as to whether the semi-static uplink transmission will be performed and whether the semi-static uplink transmission is associated with a higher priority level than the overlapping uplink transmission on the SCG. This uncertainty may result in a waste of computing resources and inefficient allocation of MCG and / or SCG resources.

[0060] Some techniques and devices described herein provide dynamic power control techniques for priority-based uplink communications based at least in part on the corresponding priority levels of the uplink communications and at least in part on the deadlines for dynamic power control. For example, some techniques and devices described herein selectively modify or determine not to modify the transmit power of the uplink transmission on the SCG based at least in part on whether to perform semi-static uplink transmission on the MCG and / or the corresponding priority levels of the semi-static uplink transmission on the MCG and the uplink transmission on the SCG. In this way, the UE can determine the power control configuration for the uplink transmission and the semi-static uplink transmission, which can enable the use of semi-static uplink transmission in a dynamic power control NR-DC system. Therefore, resource utilization and power control on the uplink can be improved, and the performance of URLLC transmission can be improved.

[0061] Figure 3 is a diagram illustrating an example 300 of transmission of a first transmission on an MCG and a second transmission on an SCG according to the present disclosure. Example 300 shows an MCG component carrier (CC) and an SCG CC. For example, the operations shown in example 300 may be performed by a UE (eg, UE 120).

[0062] As shown, the UE may receive a UL DCI 310 on an MCG CC. For example, the UL DCI 310 may schedule a PUSCH 320 on the MCG CC. In this case, the PUSCH may be referred to as a DG PUSCH. As further shown, the UE may receive the UL DCI 310 before a deadline 330. For example, the deadline 330 may be defined by T0-T_offset, where T0 is the start of a PUSCH 340 (which may correspond to an uplink transmission) and T_offset is an offset time relative to T0. The PUSCH 340 may be scheduled by a UL DCI 350. The UE may not expect the UL DCI to schedule a PUSCH on the MCG that overlaps with a PUSCH on the SCG after the deadline 330 because, in this case, it may be difficult for the UE to perform power management for the MCG and the SCG.

[0063] When the UE performs dynamic power sharing for the MCG and SCG, the transmit power of the MCG may affect the transmit power of the SCG, as shown by reference numeral 360. For example, for the transmit power determination of the PUSCH 320, the UE may not be required to account for the transmit power of the SCG. This may be referred to as the intra-MCG carrier aggregation power allocation procedure of 3GPP Release 15. For the transmit power determination of the PUSCH 340, the UE may account for the overlapping MCG uplink transmissions (e.g., PUSCH 320) scheduled before the deadline 330. For example, the UE may determine the maximum transmit power of the SCG as min{P SCG ,P total(总) –MCG tx power (transmit power)}, where P SCG is the baseline transmit power of PUSCH 340, P total is the maximum UE transmit power, and MCG txpower is the transmit power of PUSCH 320. For SCG transmissions starting at T0, the network may not schedule overlapping MCG uplink transmissions after T0-T_offset. However, in some cases, transmissions on the MCG may be initiated after the deadline 330 (e.g., uplink data may arrive for transmission on the MCG). The techniques and devices described herein provide a dynamic power sharing scheme for scenarios when transmissions on the MCG are initiated after the deadline 330. In some aspects, the UE may receive a skip or cancel indication indicating that the configured granted resources will not be used on the uplink. The indication may arrive before the deadline or after the deadline. In combination Figure 4 To describe the UE's handling of this indication.

[0064] In some aspects, DCI 310 and / or DCI 350 may indicate a priority level. For example, DCI 310 may indicate a priority level for PUSCH 320 and / or DCI 350 may indicate a priority level for PUSCH 340. In this case, the UE may first resolve overlapping PUSCH / PUCCH transmissions with the same priority level across carriers using a 3GPP Release 15 approach, and may then resolve overlapping PUSCH / PUCCH transmissions associated with different priority levels using the techniques described above. In some aspects, the UE may determine a priority level for communications that are not associated with the DCI. For example, a configured grant transmission may be transmitted on a resource allocation associated with a particular priority level.

[0065] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.

[0066] Figure 4 4 is a diagram illustrating an example 400 of determining a power sharing configuration based at least in part on a semi-static uplink transmission initiated after a deadline in accordance with the present disclosure. The operations described in example 400 may be performed by a UE configured for NR-DC dynamic power sharing (e.g., UE 120, etc.). As shown, example 400 involves an MCG CC and an SCG CC.

[0067] As in Figure 4 In the figure and indicated by reference numeral 405, in some aspects, uplink (UL) data may arrive after the deadline 410 for transmission on the MCG CC. For example, the UL data may arrive from a higher layer of the UE (e.g., an application layer, etc.) to a lower layer of the UE (such as a medium access control layer, a physical layer, etc.). Since the UE is configured with NR-DC dynamic power sharing, the UE may transmit the UL data on a configured granted PUSCH (shown as a CG PUSCH). As further shown, the configured granted PUSCH on the MCG may be associated with a high priority level, while the PUSCH on the SCG may be associated with a low priority level (e.g., lower than the high priority level).

[0068] If the UE is to receive or generate a skip or cancel indication for a configured granted PUSCH, the UE may determine that the configured granted PUSCH will not be used and the transmit power on the SCG may not be reduced. For example, in a first approach, if the UE receives or generates a skip or cancel indication for a semi-static MCG UL transmission before the deadline T0–T_offset, the skip or cancel indication may be taken into account, and if the skip or cancel indication does not appear until the deadline T0–T_offset has passed (as shown in reference numeral 405), the UE may assume that the semi-static MCG UL transmission will be transmitted for the purpose of dynamic power sharing. In a second approach, the UE may assume that the semi-static MCG UL transmission will be transmitted regardless of whether the skip or cancel indication is received before the deadline or when the skip or cancel indication is received before the deadline. In a third approach, the UE may determine whether to take the skip or cancel indication into account for the purpose of dynamic power configuration (e.g., one of the first or second approaches described above may be selected). In a fourth approach, the UE may use one of the above approaches for the primary cell, and may use another of the above approaches for the secondary cell.

[0069] As shown at reference numeral 415, the UE may determine a power sharing configuration for the PUSCH on the MCG and the PUSCH on the SCG. In example 400, the UE does not take into account the respective priority levels of the uplink transmissions on the MCG and the uplink transmissions on the SCG. For an example in which the UE takes these respective priority levels into account, refer to Figure 5 and Figure 6 .

[0070] In some aspects, the UE may determine the power sharing configuration based on the assumption that a semi-static uplink transmission on the MCG will be transmitted regardless of whether a skip or cancel indication associated with the semi-static uplink transmission is received. In this case, the UE may reduce the transmit power of the SCG even if a skip or cancel notification is received before the deadline. In some aspects, the UE may determine the power sharing configuration based on the assumption that a semi-static uplink transmission on the MCG will be transmitted only if the UE does not receive a skip or cancel indication before the deadline. In this case, if the UE receives a skip or cancel indication after the deadline, the UE may still determine the power sharing configuration based on the assumption that the semi-static uplink transmission on the MCG will be transmitted. In some aspects, the UE may select one of the above methods for determining the power sharing configuration. In some aspects, the UE may select a method based at least in part on whether the MCG is associated with the UE's primary cell or with the UE's secondary cell.

[0071] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.

[0072] Figure 5 1 is a diagram illustrating an example 500 of determining a power sharing configuration based at least in part on a semi-static uplink transmission initiated after a deadline in accordance with the present disclosure. The operations described in example 500 may be performed by a UE configured for NR-DC dynamic power sharing (e.g., UE 120, etc.). As shown, example 500 involves an MCG CC and an SCG CC.

[0073] like Figure 5 As shown in , UL data may arrive after the deadline for transmission on the MCG CC. As further shown, UL data may be associated with a high priority level and transmission on the SCG may be associated with a low priority level. Therefore, as shown in reference numeral 510, the UE may determine the power sharing configuration for the PUSCH on the MCG and the PUSCH on the SCG based on the assumption that the MCG transmission will occur regardless of whether a skip or cancel indication is received before or after the deadline or when the skip or cancel indication is received before or after the deadline. For example, if the sum of the transmit power of the PUSCH on the SCG and the PUSCH on the MCG exceeds the maximum UE transmit power of the UE, the UE may reduce the transmit power of the PUSCH on the SCG regardless of whether a skip or cancel indication is received or whether the PUSCH on the MCG has been initiated. In this way, the UE may conservatively determine the power sharing configuration, which may improve the performance of the PUSCH on the MCG in situations where the UE is power limited between the PUSCH on the MCG and the PUSCH on the SCG.

[0074] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.

[0075] Figure 6 600 is a diagram illustrating an example of determining a power sharing configuration based at least in part on a semi-static uplink transmission initiated after a deadline in accordance with the present disclosure. The operations described in example 600 may be performed by a UE configured for NR-DC dynamic power sharing (e.g., UE 120, etc.). As shown, example 600 involves an MCG CC and an SCG CC.

[0076] like Figure 6As shown in , UL data may arrive for transmission on the MCG CC after the deadline. As further shown, the UL data may be associated with a high priority level and the transmission on the SCG may be associated with a low priority level. Therefore, as shown by reference numeral 610, based at least in part on the UL data being associated with the high priority level, the UE may determine a power sharing configuration for the PUSCH on the MCG and the PUSCH on the SCG, wherein the transmit power of the PUSCH on the SCG is cut midway through the PUSCH on the SCG. For example, the UE may reduce the transmit power of the PUSCH on the SCG for a specific length of time (e.g., T_offset or a different length of time) after the UL data arrives for transmission, as shown by the notch in the PUSCH on the SCG at reference numeral 620. In this case, the PUSCH on the SCG may experience phase discontinuity in some aspects. This approach may enable the UE to use a baseline transmit power for the PUSCH on the SCG until UL data is to be transmitted on the MCG, and then reduce the transmit power on the SCG to accommodate the transmission on the MCG. Thus, when no transmission on the MCG is to be performed, the transmit power on the SCG is increased. As used herein, "reducing transmit power" may include reducing transmit power to any value including zero.

[0077] As indicated above, Figure 6 are provided as examples. Other examples may differ from those described herein. Figure 6 Examples described.

[0078] Figure 7 is a diagram illustrating an example process 700, performed, for example, by a UE, in accordance with the present disclosure. Example process 700 is an example of operations in which a UE (eg, UE 120, etc.) performs operations associated with dynamic power control for priority-based traffic.

[0079] like Figure 7 As shown in , in some aspects, process 700 may include determining a deadline before a first uplink transmission associated with an SCG, where the first uplink transmission is associated with a first priority level (block 710). For example, the UE (e.g., using the controller / processor 280, etc.) may determine a deadline before a first uplink transmission associated with the SCG, as described above. In some aspects, the first uplink transmission is associated with the first priority level.

[0080] If further Figure 7As shown in , in some aspects, process 700 may include determining whether to perform a second uplink transmission associated with the MCG, wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level (block 720). For example, the UE (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, etc.) may determine whether to perform a second uplink transmission associated with the MCG, as described above. In some aspects, the second uplink transmission is initiated after the deadline. In some aspects, the second uplink transmission is associated with a second priority level.

[0081] If further Figure 7 , in some aspects, process 700 may include adjusting the transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform a second uplink transmission, or the first priority level and the second priority level (block 730). For example, the UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may adjust the transmit power of the first uplink transmission based at least in part on the at least one, as described above.

[0082] Process 700 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0083] In a first aspect, adjusting the transmit power of the first uplink transmission is performed regardless of the first priority level and the second priority level.

[0084] In a second aspect, alone or in combination with the first aspect, when the first priority level satisfies the priority threshold, adjusting the transmit power of the first uplink transmission is performed as if the second uplink transmission is to be performed, regardless of whether the second uplink transmission is initiated.

[0085] In a third aspect, either alone or in combination with one or more of the first and second aspects, adjusting the transmit power of the first uplink transmission is performed based at least in part on the first priority level failing to satisfy a priority threshold, regardless of the first priority level and the second priority level.

[0086] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, adjusting the transmit power of the first uplink transmission includes reducing the transmit power of the first uplink transmission based at least in part on the first priority level satisfying a priority threshold and the second uplink transmission being initiated after the deadline.

[0087] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the transmit power of the first uplink transmission is reduced midway through the first uplink transmission.

[0088] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the first uplink transmission is associated with a phase discontinuity based at least in part on a transmit power of the first uplink transmission being reduced midway through the first uplink transmission.

[0089] although Figure 7 An example block diagram of process 700 is shown, but in some aspects, process 700 may include Figure 7 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in the process 700. Additionally or alternatively, two or more blocks of the process 700 may be executed in parallel.
