AI Technical Summary
The existing wireless communication technology is difficult to effectively handle the uplink transmission set with overlapping priorities in dynamic power control, resulting in improper power sharing configuration, affecting communication quality and efficiency.
By identifying and scheduling the overlapping uplink transmission set between the primary cell group (MCG) and the secondary cell group (SCG) between the user equipment (UE) and the base station, the power sharing configuration is determined based on the priority level and the lower priority transmission is discarded to optimize dynamic power sharing.
A more refined power sharing configuration is realized, the support capability for high-priority communication is improved, communication quality and efficiency are enhanced, and ambiguity and resource waste are reduced in network operations.

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 976,104, filed on February 13, 2020, entitled “DYNAMIC POWER CONTROL WITH PRIORITY INDICATIONS,” and U.S. Non-Provisional Patent Application No. 17 / 173,797, filed on February 11, 2021, entitled “DYNAMIC POWER CONTROL WITH PRIORITY INDICATIONS,” 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 with priority indication.
[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 the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by 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.

[0029] Detailed Description
[0030] 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.
[0031] 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.
[0032] 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).
[0033] 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, 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, 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.
[0034] 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 1 In 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. The 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.
[0035] 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.
[0036] 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 , relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.
[0037] 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).
[0038] 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.
[0039] 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.
[0040] 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 coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0041] 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.
[0042] 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.
[0043] 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 100 can communicate using an operating band having a first frequency range (FR1) and / or can communicate using an operating band having a second frequency range (FR2), the first frequency range (FR1) can span 410 MHz to 7.125 GHz, and the second frequency range (FR2) can span 24.25 GHz to 52.6 GHz. 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 the terms "sub-6 GHz" and the like, if used herein, may broadly refer to 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 the terms "millimeter wave" and the like, if used herein, may 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 may be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0044] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.
[0045] 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.
[0046] 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.
[0047] 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 channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of UE 120 may be included in a housing.
[0048] 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.
[0049] 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).
[0050] 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 3-7 As described.
[0051] 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 3-7 As described.
[0052] 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 with priority indication, 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 6 The process of 600 Figure 7 , and / or operations of 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 6 The process of 600 Figure 7 In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0053] In some aspects, UE 120 may include: means for identifying one or more overlaps between a first uplink transmission set on one or more primary cell groups (MCGs) and a second uplink transmission set on one or more secondary cell groups (SCGs), wherein the first uplink transmission set is associated with a respective first priority level and the second uplink transmission set is associated with a respective second priority level; means for determining a power sharing configuration for the first uplink transmission set and the second uplink transmission set based at least in part on identifying the one or more overlaps; means for discarding one or more transmissions in at least one of the first uplink transmission set or the second uplink transmission set based at least in part on the respective first priority level and the respective second priority level; and so on. In some aspects, such means may include in conjunction with 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.
[0054] In some aspects, the base station 110 may include: means for scheduling a first uplink transmission set on one or more MCGs and a second uplink transmission set on one or more SCGs, the first uplink transmission set and the second uplink transmission set having one or more overlaps, wherein the first uplink transmission set is associated with a corresponding first priority level and the second uplink transmission set is associated with a corresponding second priority level; means for determining a power sharing configuration for the first uplink transmission set and the second uplink transmission set based at least in part on the one or more overlaps; and means for receiving remaining transmissions in the first uplink transmission set and the second uplink transmission set excluding one or more discarded transmissions in at least one of the first uplink transmission set or the second uplink transmission set based at least in part on the corresponding first priority level and the corresponding second priority level; etc. In some aspects, such means may include a means for combining Figure 2 One or more components of base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.
[0055] although Figure 2 The 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.
[0056] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.
[0057] Dual Connectivity (DC) provides a way for a UE to connect to a network (or multiple networks) via multiple cells. A DC configuration may involve a set of primary cells referred to as a primary cell group (MCG) and a set of secondary cells referred to as a secondary cell group (SCG). The MCG may be associated with a primary node (e.g., provided by the primary node), and the SCG may be associated with a secondary node. The primary node may be referred to as an anchor node. The UE may perform an initial registration with an anchor node (or an MCG associated with an anchor node). The anchor node may add one or more secondary cells to the SCG of the UE. Thus, the MCG provided by the primary node may be used as a control entity, and the SCG may be utilized to provide additional data capacity. One type of DC is New Radio Dual Connectivity (NR-DC), in which both the MCG and the SCG are associated with a 5G / NR node.
[0058] Power sharing can be implemented to balance power consumption between the MCG and the SCG. In NR-DC power sharing, transmissions to the MCG can be prioritized over transmissions to the SCG. If transmissions to the MCG and the SCG overlap in time, and if the sum of the transmit power for the MCG and the SCG will exceed the maximum available transmit power for transmissions across the MCG and the SCG, the UE can reduce the transmit power for the SCG. In order to provide sufficient time to adjust the SCG transmit power, the UE can determine a deadline by which overlapping transmissions must be detected. For example, downlink control information (DCI) (or another appropriate physical downlink control channel (PDCCH) message) can 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 can determine a deadline of T0-T_offset. If the UE receives DCI for scheduling uplink transmissions to the MCG that overlap in time with scheduled SCG uplink transmissions before the deadline, the UE may reduce the transmit power of the SCG uplink transmissions. If the UE receives DCI for scheduling uplink transmissions to the MCG that overlap in time with scheduled SCG uplink transmissions after the deadline, the UE may not reduce the SCG uplink transmit power. This is because the specifications provided by the relevant communication protocols (such as, 5G / NR protocols) ensure that the UE will not receive DCI from the network after the deadline that schedules MCG uplink transmissions that overlap in time with scheduled SCG uplink transmissions.
[0059] Some communications or resource allocations may be associated with a priority level. For example, the 3GPP Release 16 specification relating to Ultra Reliable Low Latency Communications (URLLC) may introduce 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 physical uplink shared channel (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:
[0060] PUCCH with high priority compared to PUSCH / PUCCH with priority: discard PUSCH / PUCCH with low priority;
[0061] PUSCH with high priority compared to PUCCH with low priority: discard the PUCCH with low priority;
[0062] Dynamically granted (DG) PUSCH with high priority versus configured grant (CG) PUSCH with low priority: discard CG-PUSCH with low priority;
[0063] CG-PUSCH with high priority compared to DG-PUSCH with low priority: DG-PUSCH with low priority is discarded;
[0064] · CG-PUSCH with high priority compared to CG-PUSCH with low priority: the CG-PUSCH with low priority is discarded.
[0065] Thus, the UE may resolve overlapping transmissions associated with different priority levels.
[0066] In some cases, the UE may identify overlapping transmissions in an MCG and / or in an SCG. In addition, the UE may determine that the maximum transmit power of the UE will be exceeded when transmitting overlapping transmissions. In situations where overlapping transmissions are associated with corresponding priority levels, it may not be clear how the UE should handle dynamic power sharing with different priority levels. For example, it may not be clear how different combinations of priority levels for different types of communications on MCGs and SCGs should be handled. This ambiguity may result in underpowered or discarded emergency communications and / or inefficient allocation of transmit power and / or resources for lower priority communications.
[0067] Some techniques and devices described herein provide power sharing (such as dynamic power sharing) for priority-based communications in an NR-DC configuration. For example, in some aspects, the UE may perform priority handling in the SCG and MCG (e.g., lower priority communications in each cell group may be discarded), and then a power sharing configuration for the remaining communications in the SCG and MCG may be determined. In some aspects, the UE may determine a corresponding power sharing configuration for a transmission group associated with each priority level, and then the lower priority transmission group may be discarded. In this way, the UE may determine a power sharing configuration for multiple communications associated with corresponding priority levels (e.g., for dynamic spectrum sharing). As a result, higher priority traffic may be prioritized with respect to transmission and / or transmit power, thereby increasing the likelihood that higher priority traffic (particularly on the MCG) is received. In addition, these approaches for power sharing configuration may reduce ambiguity in network operation, thereby saving computing resources that would otherwise be used to repeatedly transmit failed communications due to inappropriate power sharing.
[0068] Figure 3 300 is a diagram illustrating a 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. The operations shown in example 300 may be performed by a UE (e.g., UE 120). The CC may correspond to a serving cell, such as a cell of an MCG or an SCG.
[0069] As shown, the UE may receive UL DCI 310 on the 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 dynamically granted (DG) PUSCH. As further shown, the UE may receive 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 an uplink transmission 340 and T_offset is an offset time relative to T0. The uplink transmission 340 may be scheduled by 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.
[0070] 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 uplink transmission 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 总 –MCG transmit power}, where P SCG is the baseline transmit power for uplink transmission 340, P 总 is the maximum UE transmit power, and MCG transmit power 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.
[0071] 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 uplink transmission 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.
[0072] As indicated above, Figure 3 are provided as examples. Other examples may differ from those described herein. Figure 3 Examples described.
[0073] Figure 4 4 is a diagram illustrating an example 400 of determining a power control configuration for overlapping uplink transmissions on MCG and SCG according to the present disclosure. Example 400 is an example in which priority handling is first performed within each cell group (described as step A), and dynamic power sharing is performed after priority handling (described as step B). Figure 4 The described operations may be performed by a UE (eg, UE 120 ).
[0074] Example 400 shows an MCG 405 and an SCG 410. The MCG 405 and the SCG 410 are shown as two rows to illustrate overlapping communications on the MCG 405 and the SCG 410. As shown, the MCG is associated with a first uplink transmission 415 (e.g., PUCCH), which overlaps with a second uplink transmission 420 (e.g., PUSCH). The first uplink transmission 415 is associated with a first priority level (e.g., priority 0, which is a lower priority level in example 400), while the second uplink transmission 420 is associated with a second priority level (e.g., priority 1, which is a higher priority level in example 400). As further shown, the SCG is associated with a third uplink transmission 425 (e.g., PUSCH) having a lower priority level, which overlaps with a fourth uplink transmission 430 (e.g., PUCCH) having a higher priority level. Furthermore, uplink transmissions 415, 420, 425, and 430 all at least partially overlap with one another.
[0075] As in Figure 4 435 and 440, the UE may first discard the one or more overlapping communications on each cell group based at least in part on their respective priority levels (e.g., in step A). For example, as shown by reference numeral 435, the UE may discard the first uplink transmission 415 based at least in part on the first uplink transmission 415 being associated with a lower priority level than the second uplink transmission 420. As another example, as shown by reference numeral 440, the UE may discard the third uplink transmission 425 based at least in part on the third uplink transmission 425 being associated with a lower priority level than the fourth uplink transmission 430. As such, the UE may determine a remaining set of transmissions (e.g., the second uplink transmission 420 and the fourth uplink transmission 430).
[0076] As indicated by reference numeral 445, the UE may determine a power sharing configuration for the remaining transmission set. The power sharing configuration indicates corresponding transmit powers for one or more communications on the MCG and one or more communications on the SCG. A UE transmitting communications according to the power sharing configuration may transmit communications using the transmit power indicated by the power sharing configuration. For example, if the UE is power limited (e.g., if the sum of the transmit powers of the remaining transmission sets exceeds the maximum UE transmit power of the UE), the UE may reduce the transmit power on the SCG so that the sum of the transmit powers does not exceed the maximum UE transmit power. In some aspects, the UE may not modify the uplink transmit power of the MCG, which improves uplink performance on the MCG.
[0077] In some cases, UE 120 may prioritize lower priority transmissions on the MCG over higher priority transmissions on the SCG based at least in part on discarding one or more overlapping communications on each cell group based at least in part on the respective priority levels, and a determination of a power sharing configuration for the remaining set of transmissions. For example, if first uplink transmission 415 has a priority level of 0, second uplink transmission 420 has a priority level of 1, third uplink transmission 425 has a priority level of 2, and fourth uplink transmission 430 has a priority level of 3 (thus third uplink transmission 425 and fourth uplink 430 have higher priority levels than first uplink transmission 415 and second uplink transmission 420), UE 120 may discard first uplink transmission 415 and third uplink transmission 425. Next, if UE 120 is power limited, UE 120 may determine a power sharing configuration that limits (e.g., reduces) the transmit power of the SCG, regardless of the fourth uplink transmission 430 being associated with a higher priority level than the second uplink transmission 420. Thus, transmissions on the MCG are prioritized over transmissions on the SCG, regardless of the relative priority levels of the transmissions, thereby improving the reliability of MCG signaling and reducing the occurrence of radio link failures due to the inability to communicate control information.
[0078] As shown by reference numeral 450, T0 (and thus the deadline 455) may be measured relative to the remaining uplink transmissions of the SCG (e.g., the fourth uplink transmission 430). Thus, the UE may only consider as valid the MCG transmissions scheduled by the UL DCI received before the deadline 455. Here, both transmissions on the MCG are scheduled by the UL DCI received before the deadline 455, so both transmissions on the MCG are considered valid.
[0079] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described herein. Figure 4 Examples described.
[0080] Figure 5 1 is a diagram illustrating an example 500 of determining a power control configuration for overlapping uplink transmissions on MCGs and SCGs according to the present disclosure. Example 500 is an example in which dynamic power sharing is first performed within each priority group (described as step A), and priority-based discarding of uplink transmissions is performed after dynamic power sharing (described as step B). Figure 5 The described operations may be performed by a UE (eg, UE 120).
[0081] Example 500 shows a first priority group 505 and a second priority group 510. The first priority group is associated with a priority level of 0 (e.g., a lower priority level), and the second priority group is associated with a priority level of 1 (e.g., a higher priority level). A first uplink transmission 515 on the MCG is associated with the first priority group 505, and a second uplink transmission 520 on the MCG is associated with the second priority group 510. Additionally, a third uplink transmission 525 on the SCG is associated with the first priority group 505, and a fourth uplink transmission 530 on the SCG is associated with the second priority group 510. The MCG and SCG are shown as two rows to illustrate overlapping communications on the MCG and SCG, such as overlapping communications within a priority cluster.
[0082] As shown by reference numeral 535, the UE may first determine respective power sharing configurations for uplink transmissions of priority groups 505 and 510 (e.g., in step A). For example, the UE may determine transmit power for uplink transmissions 525 and 530 based at least in part on the uplink transmissions 525 and 530 overlapping with uplink transmissions 515 and 520 on the MCG.
[0083] As shown by reference numeral 540, the UE may drop one or more transmissions associated with the priority group 505 (e.g., a lower priority group). For example, the UE may drop the first uplink transmission 515 based at least in part on the first uplink transmission 515 having a lower priority level than the second uplink transmission 520, and may drop the third uplink transmission 525 based at least in part on the third uplink transmission 525 having a lower priority level than the fourth uplink transmission 530. The UE may transmit the second uplink transmission 520 and the fourth uplink transmission 530 according to the power sharing configuration determined for the priority group 510.
[0084] As shown by reference numeral 545, T0 (and thus the deadline 550) may be measured relative to the remaining uplink transmissions of the SCG (e.g., the fourth uplink transmission 530). Thus, the UE may only consider as valid the MCG transmissions scheduled by the UL DCI received before the deadline 550. Here, both transmissions on the MCG are scheduled by the UL DCI received before the deadline 550, so both transmissions on the MCG are considered valid.
[0085] As indicated above, Figure 5 are provided as examples. Other examples may differ from those described herein. Figure 5 Examples described.
[0086] Figure 6is a diagram illustrating an example process 600 performed, for example, by a UE in accordance with the present disclosure. Example process 600 is an example in which a UE (eg, UE 120, etc.) performs operations associated with dynamic power control with priority indication.
[0087] like Figure 6 As shown in , in some aspects, process 600 may include identifying one or more overlaps between a first uplink transmission set on one or more MCGs and a second uplink transmission set on one or more SCGs, wherein the first uplink transmission set is associated with a corresponding first priority level and the second uplink transmission set is associated with a corresponding second priority level (block 610). For example, a UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may identify one or more overlaps between a first uplink transmission set on one or more MCGs and a second uplink transmission set on one or more SCGs, as described above. In some aspects, the first uplink transmission set is associated with a corresponding first priority level and the second uplink transmission set is associated with a corresponding second priority level.
[0088] like Figure 6 As further shown in FIG. 6 , in some aspects, process 600 may include determining a power sharing configuration for the first uplink transmission set and the second uplink transmission set based at least in part on identifying the one or more overlaps (block 620). For example, the UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may determine a power sharing configuration for the first uplink transmission set and the second uplink transmission set based at least in part on identifying the one or more overlaps, as described above.
[0089] like Figure 6 As further shown in FIG. 6 , in some aspects, process 600 may include dropping one or more transmissions in at least one of the first uplink transmission set or the second uplink transmission set based at least in part on the corresponding first priority level and the corresponding second priority level (block 630). For example, the UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may drop one or more transmissions in at least one of the first uplink transmission set or the second uplink transmission set based at least in part on the corresponding first priority level and the corresponding second priority level, as described above.
[0090] Process 600 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.
[0091] In a first aspect, dropping one or more transmissions includes dropping transmissions from a first uplink transmission set and dropping transmissions from a second uplink transmission set, and determining a power sharing configuration is based at least in part on remaining transmissions in the first uplink transmission set and the second uplink transmission set.
[0092] In a second aspect, either alone or in combination with the first aspect, determining a power sharing configuration includes determining a reduced transmit power of remaining transmissions in the second uplink transmission set based at least in part on a sum of transmit powers of remaining transmissions in the first uplink transmission set and the second uplink transmission set satisfying a threshold.
[0093] In a third aspect, alone or in combination with one or more of the first and second aspects, the remaining transmissions in the second uplink transmission set are associated with a higher priority level than the remaining transmissions in the first uplink transmission set.
[0094] In a fourth aspect, alone or in combination with one or more of the first and third aspects, the power sharing configuration indicates that the transmit power of remaining transmissions in the first uplink transmission set is not affected by the transmit power of remaining transmissions in the second uplink transmission set.
[0095] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the threshold is related to a maximum UE transmit power.
[0096] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the discarded transmissions from the first uplink transmission set and the discarded transmissions from the second uplink transmission set are associated with a priority level lower than a priority level associated with remaining transmissions in the first uplink transmission set and the second uplink transmission set.
[0097] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, a deadline for scheduling transmissions on one or more MCGs is determined based at least in part on initiation of remaining transmissions in a second uplink transmission set.
[0098] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, dropping one or more transmissions is performed prior to determining a power sharing configuration.
[0099] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, determining a power sharing configuration is performed prior to dropping one or more transmissions.
[0100] In the tenth aspect, alone or in combination with one or more of the first to ninth aspects, determining the power sharing configuration further includes reducing the corresponding transmit power of the second uplink transmission set based at least in part on the sum of the transmit powers of overlapping transmissions in the first uplink transmission set and the second uplink transmission set satisfying a threshold.
[0101] In an eleventh aspect, alone or in combination with one or more of the first to tenth aspects, the lower priority transmission group includes transmissions in the first uplink transmission set and transmissions in the second uplink transmission set.
[0102] In a twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, the lower priority transmission group is associated with a lower priority level than the priority levels associated with the remaining transmissions in the first uplink transmission set and the second uplink transmission set.
[0103] In a thirteenth aspect, either alone or in combination with one or more of the first to twelfth aspects, for a given priority level, a deadline for scheduling transmissions on one or more MCGs is determined at least in part based on the start of transmissions in a second uplink transmission set associated with the given priority level.
[0104] although Figure 6 An example block diagram of process 600 is shown, but in some aspects, process 600 may include Figure 6 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in process 600. Additionally or alternatively, two or more blocks of process 600 may be executed in parallel.
[0105] Figure 7 is a diagram illustrating an example process 700 performed, for example, by a base station in accordance with the present disclosure. Example process 700 is an example of operations in which a base station (eg, base station 110, etc.) performs operations associated with dynamic power control with priority indication.
[0106] like Figure 7As shown in FIG. 7 , in some aspects, process 700 may include scheduling a first uplink transmission set on one or more MCGs and a second uplink transmission set on one or more SCGs, the first uplink transmission set and the second uplink transmission set having one or more overlaps, wherein the first uplink transmission set is associated with a respective first priority level and the second uplink transmission set is associated with a respective second priority level (block 710). For example, a base station (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.) may schedule a first uplink transmission set on one or more MCGs and a second uplink transmission set on one or more SCGs, the first uplink transmission set and the second uplink transmission set having one or more overlaps, as described above. In some aspects, the first uplink transmission set is associated with a respective first priority level and the second uplink transmission set is associated with a respective second priority level.
[0107] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include determining a power sharing configuration for the first uplink transmission set and the second uplink transmission set based at least in part on the one or more overlaps (block 720). For example, the base station (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.) may determine a power sharing configuration for the first uplink transmission set and the second uplink transmission set based at least in part on the one or more overlaps, as described above.
[0108] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include receiving remaining transmissions in the first uplink transmission set and the second uplink transmission set excluding one or more discarded transmissions in at least one of the first uplink transmission set or the second uplink transmission set based at least in part on the respective first priority level and the respective second priority level (block 730). For example, the base station (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, etc.) may receive remaining transmissions in the first uplink transmission set and the second uplink transmission set excluding one or more discarded transmissions in at least one of the first uplink transmission set or the second uplink transmission set based at least in part on the respective first priority level and the respective second priority level, as described above.
[0109] 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.
[0110] In a first aspect, transmissions from a first uplink transmission set and transmissions from a second uplink transmission set are dropped, and determining a power sharing configuration is based at least in part on the remaining transmissions.
[0111] In a second aspect, alone or in combination with the first aspect, determining the power sharing configuration includes determining a reduced transmit power of remaining transmissions in the second uplink transmission set based at least in part on a sum of transmit powers of the remaining transmissions satisfying a threshold.
[0112] In a third aspect, alone or in combination with one or more of the first and second aspects, the power sharing configuration indicates that transmit power of remaining transmissions in the first uplink transmission set is not to be curtailed.
[0113] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the threshold is related to a maximum user equipment transmit power.
[0114] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the discarded transmissions from the first uplink transmission set and the discarded transmissions from the second uplink transmission set are associated with a priority level lower than the priority level associated with the remaining transmissions in the first uplink transmission set and the second uplink transmission set.
