Description

Technical Field

[0001] The present application relates to wireless communication systems, and more particularly to dynamic switching between power mode configurations. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems are capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). A wireless multiple-access communication system may include multiple base stations (BSs), each of which simultaneously supports communication for multiple communication devices, which may also be referred to as user equipment (UE).

[0003] To meet the growing demand for extended mobile broadband connections, wireless communication technology is evolving from Long Term Evolution (LTE) technology to next-generation New Radio (NR) technology. For example, NR is designed to provide lower latency, higher bandwidth or higher throughput, and higher reliability than LTE. NR is designed to operate on a wide array of spectrum bands, for example, from low-frequency bands below about 1 gigahertz (GHz) and mid-frequency bands from about 1 GHz to about 6 GHz, to high-frequency bands such as millimeter wave (mmWave) bands. NR is also designed to operate across different spectrum types, from licensed spectrum to unlicensed and shared spectrum. Spectrum sharing enables operators to have the opportunity to aggregate spectrum to dynamically support high-bandwidth services. Spectrum sharing can extend the benefits of NR technology to operating entities that may not have access to licensed spectrum. Summary of the invention

[0034] The detailed description set forth below, in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0035] The present disclosure generally relates to wireless communication systems, also referred to as wireless communication networks. In various embodiments, these techniques and equipment can be used in wireless communication networks, such as code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, orthogonal FDMA (OFDMA) networks, single carrier FDMA (SC-FDMA) networks, LTE networks, global mobile communication systems (GSM) networks, fifth generation (5G) or new air interface (NR) networks and other communication networks. As described herein, the terms "network" and "system" can be used interchangeably.

[0036] OFDMA network can realize radio technology, such as evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM, etc. UTRA, E-UTRA and GSM are part of Universal Mobile Telecommunication System (UMTS). In particular, Long Term Evolution (LTE) is a version of UMTS using E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided by an organization named "3rd Generation Partnership Project" (3GPP), and cdma2000 is described in documents provided by an organization named "3rd Generation Partnership Project 2" (3GPP2). These different radio technologies and standards are known or under development. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration between telecommunication association groups to define globally applicable third generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP project aimed at improving UMTS mobile phone standards. 3GPP may define specifications for next generation mobile networks, mobile systems, and mobile devices. The present disclosure relates to the evolution of wireless technology from LTE, 4G, 5G, NR, and sharing access to wireless spectrum between networks using a set of new and different radio access technologies or radio air interfaces.

[0037] Specifically, 5G networks consider different deployments, different spectrums, and different services and devices that can be implemented using a unified air interface based on OFDM. To achieve these goals, in addition to developing new air interface technologies for 5G NR networks, further enhancements to LTE and LTE-A are also considered. 5G NR will be able to expand to provide coverage (1) Massive Internet of Things (IoT), with ultra-high density (e.g., about 1M nodes / km 2 ), ultra-low complexity (e.g., about 10 bits / second), ultra-low energy (e.g., about 10+ years of battery life), and deep coverage to reach challenging locations; (2) including mission-critical control with strong security to protect sensitive personal, financial, or classified information, ultra-high reliability (e.g., about 99.9999% reliability), ultra-low latency (e.g., about 1 millisecond (ms)), and users with wide-area mobility or lack of mobility; and (3) enhanced mobile broadband, including extremely high capacity (e.g., about 10 Tbps / km 2 ), extremely high data rates (e.g., multi-Gbps rates, 100+Mbps user experience rates), and deep awareness for advanced discovery and optimization.

[0038] 5G NR can be implemented using an optimized OFDM-based waveform with scalable parametrics and transmission time intervals (TTI); a general, flexible framework to efficiently multiplex services and features using dynamic, low-latency time division duplex (TDD) / frequency division duplex (FDD) designs; advanced wireless technologies such as massive multiple-input multiple-output (MIMO), robust millimeter wave (mmWave) transmission, advanced channel coding, and device-centric mobility. The scalability of parametrics in 5G NR, as well as the scaling of subcarrier spacing, can effectively address the problem of operating different services on different spectrums and different deployments. For example, in various outdoor and macro coverage deployments less than 3GHz FDD / TDD implementations, the subcarrier spacing may appear at 15 kilohertz (kHz), such as over 5, 10, 20 megahertz (MHz) bandwidths (BW). For various other outdoor and small cell coverage deployments with TDD greater than 3GHz, the subcarrier spacing on 80 / 100MHz BW may be 30kHz. For various other indoor broadband implementations, using TDD on the unlicensed portion of the 5GHz band, a subcarrier spacing of 60kHz may occur on 160MHz BW. Finally, for various deployments sending the mmWave component with 28GHz TDD, the subcarrier spacing may be 120kHz on 500MHz BW.

[0039] 5G NR's scalable parametrics facilitates scalable TTIs for different latency and quality of service (QoS) requirements. For example, shorter TTIs can be used for low latency and high reliability, while longer TTIs can be used for higher spectral efficiency. Efficient multiplexing of long and short TTIs allows transmissions to start on symbol boundaries. 5G NR also considers a subframe design with self-contained integration of UL / downlink scheduling information, data, and acknowledgment in the same subframe. The self-contained integrated subframe supports communications in unlicensed or contention-based shared spectrum, adaptive UL / downlink, which can be flexibly configured on a per-cell basis to dynamically switch between UL and downlink to meet current business needs.

[0040] Various other aspects and features of the present disclosure are further described below. It should be clear that the teachings herein can be implemented in various forms, and any specific structure, function, or both disclosed herein are merely representative and non-restrictive. Based on the teachings herein, it should be understood by those of ordinary skill in the art that an aspect disclosed herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number of aspects set forth herein can be used to implement equipment or practice methods. In addition, in addition to one or more aspects set forth herein, or in addition to one or more aspects set forth herein, other structures, functions, or structures and functions can be used to implement such equipment or practice such methods. For example, the method can be implemented as a part of a system, device, equipment, and / or implemented as an instruction stored on a computer-readable medium for execution on a processor or computer. In addition, an aspect can include at least one element of a claim.

[0041] An access point (AP) operating in a network may refer to a U-NII transceiver, which acts either as a bridge in a peer-to-peer connection, or as a connector between the wired and wireless segments of the network, or as a relay between wireless segments. Various APs, such as standard power (SP) APs or low-power indoor (LPI) APs, may operate in the network. In the present disclosure, LPI may also refer to low power (indoor or outdoor). For SP mode configuration, the BS may communicate with an automated frequency coordination (AFC) system, which may automatically determine and provide a list of which frequencies are available for use by SP APs operating in, for example, a specific frequency band (e.g., the 5.925-6.425 GHz band and the 6.525-6.875 GHz band). For LP mode configuration, the BS may not need to communicate with the AFC system. In some aspects, the BS may communicate with the AFC system for LP mode configuration.

[0042] The BS may communicate with the AFC system to, for example, determine the maximum equivalent isotropically radiated power (EIRP) and / or the maximum EIRP power spectral density (PSD). The BS may use a set of different subbands with different EIRP or PSD specifications. In some aspects, the BS may switch between a first power mode configuration and a second power mode configuration. In some cases, the first power mode configuration may be an SP mode configuration, and the second power mode configuration may be an LP mode configuration. In some cases, the first power mode configuration may be a first SP mode configuration, and the second power mode configuration may be a second mode configuration. In one instance, a wider bandwidth may require a lower PSD to maintain the same total EIRP.

[0043] The maximum transmit power of the UE may be approximately 6 dBm lower than the maximum allowed transmit power of the SP AP (e.g., BS). If the AP is in LP mode configuration, the UE may have a maximum EIRP PSD of -1 decibel milliwatt (dBm) / megahertz (MHz). The maximum transmit PSD of the UE may be approximately 6 dBm lower than the maximum allowed transmit PSD of the SP AP (e.g., BS). If the AP is in SP mode configuration, the UE may have a maximum EIRP PSD of 17 dBm / MHz or a maximum EIRP of 30 dBm. The maximum transmit power of the UE may be approximately 6 dBm lower than the maximum allowed transmit power of the SP AP (e.g., BS). As long as the AP complies with standards or regulations (e.g., regulations of the Federal Communications Commission (FCC)) and meets the requirements of the AFC system, there is no restriction on the use of subbands. For example, the AP can choose between a broadband (lower power) mode and a narrowband (higher power) mode to obtain more dimensions or improve coverage, respectively. In some cases, the AP is restricted to the frequency used to switch power mode configurations.

[0044] The BS may send a system information block (SIB) indicating the maximum transmit power of the BS to the UE. The UE may determine the maximum transmit power of the UE based on the SIB. If the AP dynamically changes its power mode configuration (e.g., SP mode configuration, LP mode configuration, etc.), it may be difficult for the UE to determine the maximum transmit EIRP or the maximum transmit EIRP PSD.

[0045] The present disclosure provides techniques for switching between power mode configurations and providing this information to a UE. In some aspects, a BS may switch between an SP mode configuration and an LP mode configuration. In some aspects, a BS may switch between a first SP mode configuration and a second SP mode configuration. Each mode configuration may have advantages for different scenarios. For example, for an SP mode configuration, the BS and the UE may transmit at high power. For an LP mode configuration, the PSD is lower than for an SP mode configuration.

[0046] Advantages of various aspects of the present disclosure may enable a BS to switch from a first power mode configuration to a second power mode configuration according to different applications. For example, a wider frequency band may require a lower PSD to maintain the same total EIRP. If the BS desires a lower PSD and desires to maintain the same total EIRP, the BS may switch from a first sub-band to a second sub-band having a wider bandwidth than the first sub-band.

[0047] Figure 1A wireless communication network 100 according to one or more aspects of the present disclosure is shown. The network 100 may be a 5G network. The network 100 includes a plurality of base stations (BSs) 105 (labeled 105a, 105b, 105c, 105d, 105e, and 105f, respectively) and other network entities. The BS 105 may be a station that communicates with the UE 115, and may also be referred to as an evolved Node B (eNB), a next generation eNB (gNB), an access point, etc. Each BS 105 may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a particular geographic coverage area of ​​the BS 105 and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0048] BS 105 may provide communication coverage for macro cells or small cells (such as pico cells or femto cells) and / or other types of cells. Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs that have subscribed to services with a network provider. Small cells such as pico cells typically cover a relatively small geographic area and may allow unrestricted access to UEs that have subscribed to services with a network provider. Small cells such as femto cells also typically cover a relatively small geographic area (e.g., a home) and, in addition to unrestricted access, may also provide restricted access to UEs associated with the femto cells (e.g., UEs in a closed subscriber group (CSG) , UEs of users in a home, etc.). The BS for a macro cell may be referred to as a macro BS. The BS for a small cell may be referred to as a small cell BS, a pico BS, a femto BS, or a home BS. In Figure 1 In the example shown, BS 105d and 105e may be conventional macro BSs, while BS 105a-105c may be macro BSs supporting one of three-dimensional (3D), full-dimensional (FD) or massive MIMO. BS 105a-105c may utilize their higher-dimensional MIMO capabilities to utilize 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. BS 105f may be a small cell BS, which may be a home node or a portable access point. BS 105 may support one or more (e.g., two, three, four, etc.) cells.

[0049] The network 100 may support synchronous or asynchronous operation. For synchronous operation, the BSs may have similar frame timing, and transmissions from different BSs may be approximately aligned in time. For asynchronous operation, the base stations may have different frame timing, and transmissions from different base stations may not be aligned in time.

[0050] UE 115 is dispersed throughout the wireless network 100, and each UE 115 can be fixed or mobile. UE 115 may also be referred to as a terminal, a mobile station, a subscriber unit, a station, etc. UE 115 may be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a wireless local loop (WLL) station, etc. In one aspect, UE 115 may be a device including a universal integrated circuit card (UICC). On the other hand, UE may be a device that does not include a UICC. In some aspects, UE 115 that does not include a UICC may also be referred to as an IoT device or an Internet of Everything (IoE) device. UE 115a-115d is an example of a mobile smart phone type device that accesses the network 100. UE 115 may also be a machine specifically configured for communication connected, including machine type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc. UE 115e-115h is an example of various machines configured for communication of access network 100. UE 115i-115k is an example of a vehicle equipped with a wireless communication device configured for communication accessing network 100. UE 115 is capable of communicating with any type of BS, whether macro BS, small cell, etc. Figure 1 , lightning (e.g., communication link) indicates wireless transmission between UE 115 and serving BS 105, desired transmission between BS 105, backhaul transmission between BSs, or bypass transmission between UE 115, where serving BS 105 is a BS designated to serve UE 115 on downlink (DL) and / or uplink (UL).

[0051] In operation, BS 105a-105c may use 3D beamforming and cooperative spatial techniques such as coordinated multi-point (CoMP) or multi-connectivity to serve UEs 115a and 115b. Macro BS 105d may perform backhaul communications with BS 105a-105c and small cell BS 105f. Macro BS 105d may also transmit multicast services that are subscribed to and received by UEs 115c and 115d. Such multicast services may include mobile TV or streaming video, or may include other services for providing community information, such as weather emergencies or alerts, such as yellow alerts or gray alerts.

[0052] The BS 105 may also communicate with a core network. The core network may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. At least some of the BSs 105 (e.g., which may be examples of gNBs or access node controllers (ANCs)) may interface with the core network via a backhaul link (e.g., NG-C, NG-U, etc.) and may perform radio configuration and scheduling for communicating with the UEs 115. In various examples, the BSs 105 may communicate with each other directly or indirectly (e.g., via a core network) via a backhaul link (e.g., X1, X2, etc.), which may be a wired or wireless communication link.

[0053] The network 100 may also support mission-critical communications with ultra-reliable and redundant links for mission-critical devices, such as UE 115e, which may be a drone. The redundant communication links with UE 115e may include links from macro BSs 105d and 105e, and a link from a small cell BS 105f. Other machine type devices such as UE 115f (e.g., a thermometer), UE 115g (e.g., a smart meter), and UE 115h (e.g., a wearable device) can communicate in a multi-step configuration through the network 100, either directly with a BS such as the small cell BS 105f and the macro BS 105e, or by communicating with another user device that relays its information to the network, such as UE 115f transmitting temperature measurement information to a smart meter, UE 115g, which then reports the information. The network 100 can also provide additional network efficiency through dynamic, low-latency TDD / FDD communications, such as V2V, V2X, C-V2X communications between UE 115i, 115j, or 115k and other UEs 115, and / or vehicle-to-infrastructure (V2I) communications between UE 115i, 115j, or 115k and BS 105.

[0054] In some implementations, the network 100 communicates using an OFDM-based waveform. An OFDM-based system can divide the system BW into multiple (K) orthogonal subcarriers, which are also commonly referred to as subcarriers, tones, frequency bands, etc. Each subcarrier can be modulated with data. In some cases, the subcarrier spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system BW. The system BW can also be divided into subbands. In other cases, the subcarrier spacing and / or the duration of the TTI can be scalable.

[0055] In some aspects, BS 105 may allocate or schedule transmission resources (e.g., in the form of time-frequency RBs) for downlink (DL) and uplink (UL) transmissions in network 100. DL refers to the transmission direction from BS 105 to UE 115, while UL refers to the transmission direction from UE 115 to BS 105. The communication may be in the form of a radio frame. A radio frame may be divided into a plurality of subframes or time slots, such as approximately 10. Each time slot may be further divided into small time slots. In FDD mode, simultaneous UL and DL transmissions may occur in different frequency bands. For example, each subframe includes a UL subframe in a UL band and a DL subframe in a DL band. In TDD mode, UL and DL transmissions occur in different time periods using the same frequency band. For example, a subset of subframes in a radio frame (e.g., a DL subframe) may be used for DL ​​transmission, while another subset of subframes in a radio frame (e.g., an UL subframe) may be used for UL transmission.

[0056] DL subframes and UL subframes can be further divided into several areas. For example, each DL or UL subframe can have a predefined area for transmitting reference signals, control information and data. Reference signals are predetermined signals that facilitate communication between BS 105 and UE 115. For example, reference signals can have a specific pilot pattern or structure, wherein pilot tones can span over BW or frequency bands, and each pilot tone is located at a predefined time and a predefined frequency. For example, BS 105 can send a cell-specific reference signal (CRS) and / or a channel state information-reference signal (CSI-RS) to enable UE 115 to estimate a DL channel. Similarly, UE 115 can send a sounding reference signal (SRS) to enable BS 105 to estimate an UL channel. Control information may include resource allocation and protocol control. Data may include protocol data and / or operational data. In some aspects, BS 105 and UE 115 may communicate using self-contained subframes. Self-contained subframes may include a portion for DL ​​communication and a portion for UL communication. A self-contained subframe may be DL-centric or UL-centric. A DL-centric subframe may include a longer duration for DL ​​communications than for UL communications. A UL-centric subframe may include a longer duration for UL communications than for DL ​​communications.

[0057] In some aspects, network 100 may be an NR network deployed on a licensed spectrum. BS 105 may send synchronization signals (e.g., including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS)) in network 100 to facilitate synchronization. BS 105 may broadcast system information associated with network 100 (e.g., including a master information block (MIB), remaining system information (RMSI), and other system information (OSI)) to facilitate initial network access. In some instances, BS 105 may broadcast PSS, SSS, and / or MIB in the form of a synchronization signal block (SSB) on a physical broadcast channel (PBCH), and may broadcast RMSI and / or OSI on a physical downlink shared channel (PDSCH).

[0058] In some aspects, a UE 115 attempting to access the network 100 may perform an initial cell search by detecting the PSS from the BS 105. The PSS may enable synchronization of periodic timing and may indicate a physical layer identification value. The UE 115 may then receive the SSS. The SSS may enable radio frame synchronization and may provide a cell identification value that may be combined with the physical layer identification value to identify a cell. The PSS and SSS may be located in the center portion of a carrier or at any suitable frequency within a carrier.

[0059] After receiving the PSS and SSS, the UE 115 may receive the MIB. The MIB may include system information for initial network access and scheduling information for RMSI and / or OSI. After decoding the MIB, the UE 115 may receive the RMSI and / or OSI. The RMSI and / or OSI may include radio resource control (RRC) information related to random access channel (RACH) procedures, paging, control resource sets (CORESET) for physical downlink control channel (PDCCH) monitoring, physical UL control channel (PUCCH), physical UL shared channel (PUSCH), power control, and SRS.

[0060] After obtaining the MIB, RMSI and / or OSI, the UE 115 may perform a random access procedure to establish a connection with the BS 105. In some examples, the random access procedure may be a four-step random access procedure. For example, the UE 115 may send a random access preamble, and the BS 105 may respond with a random access response. The random access response (RAR) may include a detected random access preamble identifier (ID) corresponding to the random access preamble, timing advance (TA) information, UL permission, a temporary cell radio network temporary identifier (C-RNTI), and / or a backoff indicator. Upon receiving the random access response, the UE 115 may send a connection request to the BS 105, and the BS 105 may respond with a connection response. The connection response may indicate contention resolution. In some examples, the random access preamble, RAR, connection request, and connection response may be referred to as message 1 (MSG1), message 2 (MSG2), message 3 (MSG3), and message 4 (MSG4), respectively. In some examples, the random access procedure may be a two-step random access procedure, where the UE 115 may send a random access preamble and a connection request in a single transmission, and the BS 105 may respond by sending a random access response and a connection response in a single transmission.

[0061] After the connection is established, the UE 115 and the BS 105 may enter a normal operation phase, in which operational data may be exchanged. For example, the BS 105 may schedule the UE 115 for UL and / or DL ​​communications. The BS 105 may send UL and / or DL ​​scheduling grants to the UE 115 via the PDCCH. The scheduling grant may be sent in the form of DL control information (DCI). The BS 105 may send DL communication signals (e.g., carrying data) to the UE 115 via the PDSCH according to the DL scheduling grant. The UE 115 may send UL communication signals to the BS 105 via the PUSCH and / or PUCCH according to the UL scheduling grant.

[0062] In some aspects, BS 105 may communicate with UE 115 using HARQ technology to improve communication reliability, for example, to provide URLLC services. BS 105 may schedule UE 115 for PDSCH communication by sending a DL grant in PDCCH. BS 105 may send DL data packets to UE 115 according to the scheduling in PDSCH. DL data packets may be sent in the form of transport blocks (TBs). If UE 115 successfully receives the DL data packet, UE 115 may send HARQ ACK to BS 105. Conversely, if UE 115 fails to successfully receive the DL transmission, UE 115 may send HARQ NACK to BS 105. When HARQ NACK is received from UE 115, BS 105 may retransmit the DL data packet to UE 115. The retransmission may include a version of the DL data encoding that is the same as the initial transmission. Alternatively, the retransmission may include a version of the encoding of the DL data that is different from the initial transmission. UE 115 may apply soft combining to combine the coded data received from the initial transmission and the retransmission for decoding.BS 105 and UE 115 may also apply HARQ to UL communications using a substantially similar mechanism as DL HARQ.

[0063] In some aspects, the network 100 can operate on a licensed frequency band, a shared frequency band, and / or an unlicensed frequency band, for example, about 3.5 gigahertz (GHz), sub-6 GHz, or higher frequencies in the mmW band. The network 100 can divide the frequency band into a plurality of channels, each of which occupies about 20 megahertz (MHz). The network 100 can operate on a system BW or a component carrier (CC) BW. The network 100 can divide the system BW into a plurality of BWPs (e.g., parts). The BS 105 can dynamically allocate the UE 115 to operate on a certain BWP (e.g., a certain part of the system BW). The allocated BWP can be referred to as an active BWP. The UE 115 can monitor the active BWP for signaling information from the BS 105. The BS 105 can schedule the UE 115 to perform UL or DL ​​communications in the active BWP. In some aspects, the BS 105 can allocate a pair of BWPs within the CC to the UE 115 for UL and DL communications. For example, a BWP pair may include one BWP for UL communication and one BWP for DL ​​communication.

[0064] An AP operating in the network 100 may refer to a U-NII transceiver, which acts either as a bridge in a peer-to-peer connection, or as a connector between wired and wireless segments of the network 100, or as a relay between wireless segments. Various APs, such as SP APs or LP APs, may operate in the network 100. For SP mode configuration, the BS 105 communicates with the AFC system, which may automatically determine and provide a list of which frequencies are available for use by SP APs operating in, for example, a specific frequency band (e.g., the 5.925-6.425 GHz band and the 6.525-6.875 GHz band).

[0065] BS 105 may communicate with the AFC system to, for example, determine the maximum EIRP and / or maximum EIRP PSD. PSD may refer to the total energy output per unit BW of a pulse or sequence of pulses where the transmit power is at its maximum level, divided by the total duration of the pulse. A pulse may refer to a continuous transmission of a sequence of modulation symbols during which the average symbol envelope power is constant. Average symbol envelope power may refer to the average value of the envelope power of each symbol taken over all symbols in the signaling alphabet. For PSD, the total time does not include the time between pulses where the transmit power is off or below its maximum level. Maximum PSD may refer to the maximum PSD within a specified measurement BW within the operating band of the U-NII device.

[0066] For LP mode configuration, BS 105 may not need to communicate with the AFC system. In some aspects, BS 105 may communicate with the AFC system for LP mode configuration.

[0067] Figure 2 2 is a table 200 illustrating device classes associated with standard power and low power APs according to one or more aspects of the present disclosure. Table 200 includes a "Device Class" column 202, an "Operating Band" column 204, a "Maximum Equivalent Isotropic Radiated Power (EIRP)" column 206, and a "Maximum EIRP PSD" column 208. In table 200, a first entry 210 illustrates that the SP AP may operate in, for example, a 5.925-6.425 GHz frequency band or a 6.525-6.875 GHz frequency band, and may have a maximum EIRP of 36 dBm and / or a maximum EIRP PSD of 23 dBm / MHz. A second entry 212 illustrates that a client connected to the SP AP may operate in, for example, a 5.925-6.425 GHz frequency band or a 6.525-6.875 GHz frequency band, and may have a maximum EIRP of 30 dBm and / or a maximum EIRP PSD of 17 dBm / MHz. The SP AP may be, for example, a Figure 1 The BS 105 in question, and the client connected to the SP AP may be, for example, Figure 1UE 115 in question. The maximum transmit power of a client (e.g., UE 115) may be 6 dBm lower than the maximum allowed transmit power of an SP AP (e.g., BS 105). In some aspects, the maximum allowed transmit power of an SP AP refers to the maximum EIRP. In some aspects, the maximum allowed transmit power of an SP AP refers to the maximum EIRP PSD.

[0068] In table 200, third entry 214 shows that the LPI AP can operate in, for example, the 5.925-6.425 GHz frequency band, the 6.425-6.525 GHz frequency band, the 6.525-6.875 GHz frequency band, or the 6.875-7.125 GHz frequency band, and can have a maximum EIRP of 30 dBm and / or a maximum EIRP PSD of 5 dBm / MHz. Fourth entry 216 shows that a client connected to the LPI AP can operate in, for example, the 5.925-6.425 GHz frequency band, the 6.425-6.525 GHz frequency band, the 6.525-6.875 GHz frequency band, or the 6.875-7.125 GHz frequency band, and can have a maximum EIRP of 24 dBm and / or a maximum EIRP PSD of -1 dBm / MHz. The LPI AP can be, for example, about Figure 1 The BS 105 in question and the client connected to the LPI AP may be, for example, Figure 1 UE 115 in question. The maximum EIRP PSD of the client (eg, UE 115) may be 6 dBm lower than the maximum EIRP PSD of the LPI AP (eg, BS 105).

[0069] The BS 105 may send a SIB indicating a maximum transmit power of the BS 105 to the UE 115. In some aspects, the SIB may include a Pmax parameter indicating the maximum transmit power of the BS 105. The UE 115 may determine the maximum transmit power of the BS 105 and / or the maximum transmit power of the UE 115 based on the maximum transmit power indicated by the SIB. The UE 115 may determine the maximum transmit power of the UE 115 by subtracting 6 dBm from the maximum transmit power of the BS 105. In some aspects, the BS 105 may configure a first UL transmission EIRP for a first UL BWP and a second UL transmission EIRP for a second UL BWP, wherein the second UL transmission EIRP is different from the first UL transmission EIRP. In some aspects, the BS 105 may configure a first UL transmission EIRP PSD for the first UL BWP and a second UL transmission EIRP PSD for the second UL BWP, wherein the second EIRP PSD is different from the first EIRP PSD.

[0070] In some aspects, the BS 105 can dynamically switch between the first power mode configuration and the second power mode configuration. Figure 3 1 shows a wireless communication network 300 according to one or more aspects of the present disclosure. The wireless communication network 300 may be incorporated into the network 100. The network 300 may include a BS 305, a UE 315a, and a UE 315b. The BS 305 may correspond to Figure 1 BS 105 in, and UE 315a and 315b may correspond to Figure 1 UE 115 in.

[0071] exist Figure 3 In the example shown, BS 305 may send a first power mode configuration 320 to UE 315a and may send a second power mode configuration 322 to UE 315b. In some aspects, BS 305 may dynamically switch between the first power mode configuration 320 and the second power mode configuration 322, but not for each UE. For example, BS 305 may serve UE 315a in the first power mode configuration 320 and may serve UE 315b in the second power mode configuration 322, but does not dynamically switch between the first power mode configuration 320 and the second power mode configuration 322 for one UE. For example, BS 305 may send a first RRC message indicating the first power mode configuration 320 to UE 315a and send a second RRC message indicating the second power mode configuration 322 to UE 315b.

[0072] like Figure 4 As shown, the first power mode configuration 320 may include an SP mode configuration corresponding to UE 315a, and the second power mode configuration 322 may include an LP mode configuration corresponding to UE 315b different from UE 315a. Figure 5 As shown, the first power mode configuration 320 may include a first SP mode configuration corresponding to UE 315a, and the second power mode configuration 322 may include a second SP mode configuration different from the first SP mode configuration, wherein the second SP mode configuration corresponds to UE 315b different from UE 315a.

[0073] Figure 4 4 is a signaling diagram illustrating a method 400 for switching between an SP mode configuration of a UE 315a and an LP mode configuration of a UE 315b according to one or more aspects of the present disclosure. The method 400 may be performed, for example, at a BS 305, a UE 315a, and / or a UE 315b (e.g., located at Figure 3 Method 400 may be implemented as in reference Figure 3The method 400 includes many of the enumerated actions, but aspects of the method 400 may include additional actions before, after, and between the enumerated actions. In some aspects, one or more of the enumerated actions may be omitted or performed in a different manner. Figure 4 Perform these actions in the order shown.

[0074] At act 402 of method 400, BS 305 may send an SP mode configuration to UE 315a, the SP mode configuration including a first transmit power parameter specific to UE 315a. The SP mode configuration may correspond to Figure 3 305 may include a first power mode configuration 320 in the SP mode configuration. For example, the BS 305 may send a first RRC message indicating the SP mode configuration 320 to the UE 315a. The UE 315a may receive the SP mode configuration from the BS 305. The first transmit power parameter included in the SP mode configuration may be, for example, a maximum transmit power specific to the UE 315a or a maximum transmit PSD specific to the UE 315a.

[0075] At act 404 of method 400, BS 305 may send an LP mode configuration including a second transmit power parameter specific to UE 315b to UE 315b. The LP mode configuration may correspond to Figure 3 For example, BS 305 may send a second RRC message indicating LP mode configuration 322 to UE 315b. UE 315b may receive the LP mode configuration from BS 305. The second transmit power parameter included in the LP mode configuration may be, for example, a maximum transmit PSD specific to UE 315b.

[0076] In some instances, the first transmit power parameter includes a first maximum transmit power specific to UE 315a and may correspond to the first maximum transmit power of BS 305. The second transmit power parameter includes a second maximum transmit power specific to UE 315b and may correspond to the second maximum transmit power of BS 305. Thus, for SP mode configuration, UE 315a may determine the maximum transmit power based on the first maximum transmit power specific to UE 315a. For example, UE 315a may configure its maximum transmit power to be approximately 6 dBm lower than the first maximum transmit power of BS 305. Additionally or alternatively, for LP mode configuration, UE 315b may determine the maximum transmit power based on the second maximum transmit power specific to UE 315b. For example, UE 315b may configure its transmit power to be approximately 6 dBm lower than the second maximum transmit power of BS 305.

[0077] In some examples, the first transmit power parameter includes a first maximum transmit PSD that is specific to UE 315a and may correspond to the first maximum transmit PSD of BS 305, and the second transmit power parameter includes a second maximum transmit PSD that is specific to UE 315b and may correspond to the second maximum transmit PSD of BS 305. Thus, UE 315a may determine the maximum transmit PSD to be approximately 6 dBm / MHz lower than the first maximum transmit PSD of BS 305. Additionally or alternatively, UE 315b may determine the maximum transmit PSD to be approximately 6 dBm / MHz lower than the second maximum transmit PSD of BS 305.

[0078] In some instances, BS 305 may include the UL maximum transmit power of UE 315 (e.g., UE 315a or UE 315b) in the DCI. For example, BS 305 may send a first DCI indicating a first power mode configuration (e.g., SP mode configuration) to UE 315a, and / or may send a second DCI indicating a second power mode configuration (e.g., LP mode configuration) to UE 315b. In one instance, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit power of UE 315a, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit power of UE 315b. In another instance, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit PSD of UE 315a, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit PSD of UE 315b.

[0079] In one instance, BS 305 may send a first DCI in a first GC-PDCCH and may send a second DCI in a second GC-PDCCH different from the first GC-PDCCH. In another instance, BS 305 may send a first DCI in a first UE-specific DCI indicating a grant including a set of first bits, and / or may send a second DCI in a second UE-specific DCI indicating a grant including a set of second bits. The DCI grant may indicate a scheduled RB set. If there are unused bits in the RB set indication field, BS 305 may use the unused bits to indicate a first power mode configuration or a second power mode configuration. The set of first bits and / or the set of second bits may indicate whether the first communication signal is transmitted based on the first power mode configuration or the second communication signal is transmitted based on the second power mode configuration, which will be further discussed below with respect to, for example, actions 406 and 408.

[0080] In action 406 of method 400, UE 315a may transmit a first communication signal based on the SP mode configuration. For example, UE 315a may transmit the first communication signal according to a first transmit power parameter included in the SP mode configuration (e.g., a maximum transmit power or a maximum transmit PSD determined by UE 315a as described above). BS 305 may receive the first communication signal based on the SP mode configuration from UE 315a.

[0081] In action 408 of method 400, UE 315b may transmit a second communication signal based on the LP mode configuration. For example, UE 315b may transmit the second communication signal according to a second transmit power parameter included in the LP mode configuration (e.g., a maximum transmit power or a maximum transmit PSD determined by UE 315b as described above). BS 305 may receive the second communication signal based on the LP mode configuration from UE 315b.

[0082] although Figure 4 The SP configuration and LP configuration indicating a first transmit power or PSD of the BS and a second transmit power or PSD of the BS are described, but it should be understood that in other examples, the SP configuration and LP configuration may indicate a first transmit power or PSD of the UE and a second transmit power or PSD of the UE.

[0083] In some aspects, BS 305 can switch between different SP mode configurations for lower EIRP. For example, a standard or regulation (e.g., FCC regulation) can specify that the maximum transmit power of UE 315a, 315b should be 6dBm lower than the maximum transmit power of BS 305. BS 305 can dynamically switch between different maximum transmit powers of UE 315a and 315, but not for each UE.

[0084] BS 305 can change the BW, but may not be able to change the maximum transmit power of UE 315a, 315b. Given the AFC information and the transmission subband selection, the transmit power of UE 315a, 315b may be determined by the worst case transmit power of BS 305. The worst case transmit power of BS 305 may be indicated in the SIB when setting the maximum transmit power of UE 315a, 315b.

[0085] Figure 5 315a and a second SP mode configuration of UE 315b according to one or more aspects of the present disclosure. The method 500 may be performed, for example, at a BS 305, a UE 315a, and / or a UE 315b (e.g., located at Figure 3 Method 500 may be implemented as in reference Figure 3The method 500 includes many of the enumerated actions, but aspects of the method 500 may include additional actions before, after, and between the enumerated actions. In some aspects, one or more of the enumerated actions may be omitted or performed in a different manner. Figure 5 Perform these actions in the order shown.

[0086] At act 502 of method 500, BS 305 may send a first SP mode configuration to UE 315a, the configuration including a first transmit power parameter specific to UE 315a. The first SP mode configuration may correspond to Figure 3 For example, BS 305 may send a first RRC message indicating the first SP mode configuration 320 to UE 315a. UE 315a may receive the first SP mode configuration from BS 305. The first transmit power parameter included in the first SP mode configuration may be, for example, a maximum transmit power specific to UE 315a.

[0087] At act 504 of method 500, BS 305 may send a second SP mode configuration to UE 315b, the second SP mode configuration including a second transmit power parameter specific to UE 315b. The second SP mode configuration may correspond to Figure 3 For example, BS 305 may send a second RRC message indicating the second SP mode configuration 322 to UE 315b. UE 315b may receive the second SP mode configuration from BS 305. The second transmit power parameter included in the second SP mode configuration may be, for example, a maximum transmit power specific to UE 315b.

[0088] In some examples, the first transmit power parameter includes a first maximum transmit power that is specific to UE 315a and based on a second maximum transmit power of BS 305, and the second transmit power parameter includes a third maximum transmit power that is specific to UE 315b and based on the second maximum transmit power of BS 305. Thus, for the first SP mode configuration, UE 315a may operate with the first maximum transmit power that is specific to UE 315a, and the first maximum transmit power may be 6 dBm lower than the second maximum transmit power of BS 305. Additionally or alternatively, for the first SP mode configuration, UE 315b may operate with a third maximum transmit power that is specific to UE 315b, and the third maximum transmit power may be 6 dBm lower than the second maximum transmit power of BS 305.

[0089] In some instances, BS 305 may include the UL maximum transmit power of UE 315 (e.g., UE 315a or UE 315b) in the DCI. For example, BS 305 may send a first DCI indicating a first power mode configuration (e.g., a first SP mode configuration) to UE 315a, and / or may send a second DCI indicating a second power mode configuration (e.g., a second SP mode configuration) to UE 315b. In one instance, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit power of UE 315a, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit power of UE 315b. In another instance, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit PSD of UE 315a, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit PSD of UE 315b.

[0090] In one instance, BS 305 may send a first DCI in a first GC-PDCCH and may send a second DCI in a second GC-PDCCH different from the first GC-PDCCH. In another instance, BS 305 may send a first DCI in a first UE-specific DCI indicating a grant including a set of first bits, and / or may send a second DCI in a second UE-specific DCI indicating a grant including a set of second bits. The DCI grant may indicate a scheduled RB set. If there are unused bits in the RB set indication field, BS 305 may use the unused bits to indicate a first power mode configuration or a second power mode configuration. The set of first bits and / or the set of second bits may indicate whether the first communication signal is transmitted based on the first power mode configuration or the second communication signal is transmitted based on the second power mode configuration, which will be further discussed below with respect to aspects such as actions 506 and 508.

[0091] In action 506 of method 500, UE 315a may transmit a first communication signal based on the first SP mode configuration. For example, UE 315a may transmit the first communication signal according to a first transmit power parameter included in the first SP mode configuration. For example, UE 315a may configure its transmit power to be approximately 6 dBm lower than the first transmit power parameter. Alternatively, UE 315a may configure its transmit PSD to be approximately 6 dBm / MHz lower than the first transmit power parameter. BS 305 may receive the first communication signal based on the first SP mode configuration from UE 315a.

[0092] In action 508 of method 500, UE 315b may transmit a second communication signal based on the second SP mode configuration. For example, UE 315b may transmit the second communication signal according to a second transmit power parameter included in the second SP mode configuration. For example, UE 315b may configure its transmit power to be approximately 6 dBm lower than the first transmit power parameter. Alternatively, UE 315b may configure its transmit PSD to be approximately 6 dBm / MHz lower than the first transmit power parameter. BS 305 may receive a second communication signal based on the second SP mode configuration from UE 315b.

[0093] In some aspects, the BS 305 may configure a first UL BWP for the first SP mode configuration and a second UL BWP for the second SP mode configuration. The first transmit power parameter included in the first SP mode configuration may include a first UL maximum transmit power of the UE 315a, and the BS 305 may use the first DL maximum transmit power when communicating with the UE 315a. Additionally or alternatively, the second transmit power parameter included in the second SP mode configuration may include a second UL maximum transmit power of the UE 315b, and the BS 305 may use the second DL maximum transmit power when communicating with the UE 315b. In some cases, the first UL maximum transmit power is different from the second UL maximum transmit power. In some cases, the first DL maximum transmit power is different from the second DL maximum transmit power.

[0094] although Figure 5 A first SP configuration and a second SP configuration indicating a first transmit power or PSD of the BS and a second transmit power or PSD of the BS are described, but it should be understood that in other examples, the first SP configuration and the second SP configuration may indicate a first transmit power or PSD of the UE and a second transmit power or PSD of the UE.

[0095] although Figure 3-Figure 5 BS 305 is shown communicating a first power mode configuration with UE 315a and communicating a second power mode configuration with UE 315b, but this is not limiting and BS 305 may communicate the first and second mode configurations with a single UE.

[0096] Figure 6 6 shows a wireless communication network 600 according to one or more aspects of the present disclosure. The wireless communication network 600 may be incorporated into the network 100. The network 600 may include a BS 605 and a UE 615. The BS 605 may correspond to Figure 1 BS 105 in, and UE 615 may correspond to Figure 1 UE 115 in.

[0097] exist Figure 6 In the example shown, the BS 605 may send a first power mode configuration 620 and a second power mode configuration 622 to the UE 615. In some aspects, for each UE, the BS 605 may dynamically switch between the first power mode configuration 620 and the second power mode configuration 622. For example, the BS 605 may serve the UE 615 in the first power mode configuration 620 and the second power mode configuration 622, and may dynamically switch between the first power mode configuration 620 and the second power mode configuration 622 for the UE 615.

[0098] BS 605 may transmit a first DL communication signal to UE 615 during a first time period based on first power mode configuration 620, and / or may transmit a second DL communication signal during a second time period based on second power mode configuration 622, wherein the second time period is different from the first time period. For example, BS 605 may transmit the first DL communication signal according to a first maximum transmit power of BS 605 and / or a first maximum transmit PSD of BS 605. UE 115 may receive the first communication signal and / or the second communication signal from BS 605.

[0099] Additionally or alternatively, UE 615 may transmit a first UL communication signal during a first time period based on first power mode configuration 620, and / or may transmit a second UL communication signal during a second time period based on second power mode configuration 622, wherein the second time period is different from the first time period. For example, UE 615 may transmit the first UL communication signal according to a first maximum transmit power of UE 615 and / or a first maximum transmit PSD of UE 115. BS 605 may receive the first communication signal and / or the second communication signal from UE 615.

[0100] As will be described below, for example Figure 7 and Figure 8 As discussed in more detail in the aspects of FIG. 6A , the first power mode configuration 620 can be associated with a first BWP and the second power mode configuration 622 can be associated with a second BWP. The second BWP can be the same as or different from the first BWP. Figure 7 As shown, the first power mode configuration 620 may include an SP mode configuration, and the second power mode configuration 622 may include an LP mode configuration, wherein the SP mode configuration and the LP mode configuration are configured for the same UE 615. Figure 8 As shown, the first power mode configuration 620 may include a first SP mode configuration, and the second power mode configuration 622 may include a second SP mode configuration different from the first SP mode configuration, wherein the first and second SP mode configurations are configured for the same UE 61 .

[0101] although Figure 6 A first SP configuration and a second SP configuration indicating a first transmit power or PSD of the BS and a second transmit power or PSD of the BS are described, but it should be understood that in other examples, the first SP configuration and the second SP configuration may indicate a first transmit power or PSD of the UE and a second transmit power or PSD of the UE.

[0102] Figure 7 7 is a signaling diagram illustrating a method 700 for switching between an SP mode configuration and an LP mode configuration according to one or more aspects of the present disclosure, wherein the SP and LP mode configurations correspond to the same UE 615. The method 700 may be performed, for example, between a BS 605 and a UE 615 (e.g., located at Figure 6 Method 700 may be implemented as in reference Figure 6 The method 700 includes many of the enumerated actions, but aspects of the method 700 may include additional actions before, after, and between the enumerated actions. In some aspects, one or more of the enumerated actions may be omitted, or may be performed in a different manner than described in the present disclosure. Figure 7 Perform these actions in the order shown.

[0103] At act 702 of method 700, BS 605 may send an SP mode configuration to UE 615, the SP mode configuration including a first transmit power parameter specific to UE 615. The SP mode configuration may correspond to Figure 6 6. In some instances, the BS 605 may send the SP mode configuration to the UE 615 in the first RRC configuration. In some instances, the BS 605 may send the SP mode configuration to the UE 615 in the first UE-specific RRC configuration. The UE 615 may receive the SP mode configuration from the BS 605. The first transmit power parameter included in the SP mode configuration may be, for example, a maximum transmit power specific to the UE 615 or a maximum transmit PSD specific to the UE 615.

[0104] At act 704 of method 700, BS 605 may send an LP mode configuration including a second transmit power parameter specific to UE 615 to UE 615. The LP mode configuration may correspond to Figure 66. In some instances, the BS 605 may send the LP mode configuration to the UE 615 in a second RRC configuration. In some instances, the BS 605 may send the LP mode configuration to the UE 615 in a second UE-specific RRC configuration. The UE 615 may receive the LP mode configuration from the BS 605. The second transmit power parameter included in the LP mode configuration may be, for example, a maximum transmit PSD specific to the UE 615.

[0105] In some instances, the BS 605 may configure a first UL maximum transmit power of the UE 615 for the first transmit power parameter configured for the SP mode, and may configure a second UL maximum transmit power of the UE 615 for the second transmit power parameter configured for the LP mode. In some instances, the BS 605 may configure a first UL maximum transmit PSD of the BS 605 for the first transmit power parameter configured for the SP mode, and may configure a second UL maximum transmit PSD of the BS 605 for the second transmit power parameter configured for the LP mode.

[0106] In some aspects, the BS 605 may send an SP-mode configuration by sending a first BWP switching configuration for switching from a second UL BWP to a first UL BWP, wherein the first UL BWP is associated with the SP-mode configuration and the second UL BWP is associated with the LP-mode configuration. The first BWP switching configuration may include an SP-mode configuration. The BS 605 may also send an LP-mode configuration by sending a second BWP switching configuration for switching from the first UL BWP to the second UL BWP. The second BWP switching configuration may include an LP-mode configuration.

[0107] In some examples, BS 605 may include the UL maximum transmit power of UE 615 in the DCI. For example, BS 605 may send a first DCI indicating a first power mode configuration (e.g., SP mode configuration) to UE 315, and / or may send a second DCI indicating a second power mode configuration (e.g., LP mode configuration) to UE 315. In one example, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit power of UE 315, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit power of UE 315. In another example, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit PSD of UE 315, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit PSD of UE 315.

[0108] In one instance, BS 305 may send a first DCI in a first GC-PDCCH and may send a second DCI in a second GC-PDCCH different from the first GC-PDCCH. In another instance, BS 305 may send a first DCI in a first UE-specific DCI indicating a grant including a set of first bits, and / or may send a second DCI in a second UE-specific DCI indicating a grant including a set of second bits. The DCI grant may indicate a scheduled RB set. If there are unused bits in the RB set indication field, BS 305 may use the unused bits to indicate a first power mode configuration or a second power mode configuration. The set of first bits and / or the set of second bits may indicate whether the first communication signal is transmitted based on the first power mode configuration or the second communication signal is transmitted based on the second power mode configuration, which will be further discussed below with respect to, for example, actions 706 and 708.

[0109] In action 706 of method 700, UE 615 may transmit a first communication signal based on the SP mode configuration. For example, UE 615 may transmit the first communication signal according to a first transmit power parameter included in the SP mode configuration. For example, UE 615 may configure its transmit power to be approximately 6 dBm lower than the first transmit power parameter. Alternatively, UE 615 may configure its transmit PSD to be approximately 6 dBm / MHz lower than the first transmit power parameter. BS 605 may receive the first communication signal based on the SP mode configuration from UE 615.

[0110] In action 708 of method 700, UE 615 may transmit a second communication signal based on the LP mode configuration. For example, UE 615 may transmit the second communication signal according to a second transmit power parameter included in the LP mode configuration. For example, UE 615 may configure its transmit power to be approximately 6 dBm lower than the second transmit power parameter. Alternatively, UE 615 may configure its transmit PSD to be approximately 6 dBm / MHz lower than the second transmit power parameter. BS 605 may receive the second communication signal based on the LP mode configuration from UE 615.

[0111] In some aspects, the first and second communication signals may be UL communication signals. For example, the UE 615 may send the first UL communication signal in the first UL BWP based on the SP mode configuration, and / or may send the second UL communication signal in the second UL BWP based on the LP mode configuration. The BS 605 may receive the first UL communication signal in the first UL BWP based on the SP mode configuration, and / or may receive the second UL communication signal in the second UL BWP based on the LP mode configuration.

[0112] although Figure 7The SP configuration and LP configuration indicating a first transmit power or PSD of the BS and a second transmit power or PSD of the BS are described, but it should be understood that in other examples, the SP configuration and LP configuration may indicate a first transmit power or PSD of the UE and a second transmit power or PSD of the UE.

[0113] In some aspects, the BS 605 can switch between different SP mode configurations for lower EIRP. For example, a standard or regulation (e.g., Federal Communications Commission (FCC) regulation) can specify that the maximum transmit power of the UE 615 should be 6 dBm lower than the maximum transmit power of the BS 605. The BS 605 can dynamically switch between different maximum DL transmit powers based on subband usage and allow the UE 615 to use different maximum transmit powers per BWP and / or different maximum transmit PSD per BWP.

[0114] Figure 8 8 is a signaling diagram illustrating a method 800 for switching between a first SP mode configuration for a UE 615 and a second SP mode configuration for a UE 615 according to one or more aspects of the present disclosure. The method 800 may be performed, for example, between a BS 605 and a UE 615 (eg, located at Figure 6 The method 600 may be implemented as in the reference Figure 6 The method 800 includes a number of enumerated actions, but aspects of the method 800 may include additional actions before, after, and between the enumerated actions. In some aspects, one or more of the enumerated actions may be omitted or performed in a different manner than described in the present disclosure. Figure 8 Perform these actions in the order shown.

[0115] In action 802 of method 800, BS 605 may send a first SP mode configuration to UE 615, the first SP mode configuration including a first transmit power parameter specific to UE 615. The first SP mode configuration may correspond to Figure 6 In some instances, the BS 605 may send the first SP mode configuration to the UE 615 in a first RRC configuration. In some instances, the BS 605 may send the first SP mode configuration to the UE 615 in a first UE-specific RRC configuration. The UE 615 may receive the first SP mode configuration from the BS 605. The first transmit power parameter included in the first SP mode configuration may be, for example, a maximum transmit power specific to the UE 615 or a maximum transmit PSD specific to the UE 615.

[0116] At act 804 of method 800, BS 605 may send a second SP mode configuration to UE 615, the second SP mode configuration including a second transmit power parameter specific to UE 615. The second SP mode configuration may correspond to Figure 6 In some instances, the BS 605 may send the second SP mode configuration to the UE 615 in a second RRC configuration. In some instances, the BS 605 may send the second SP mode configuration to the UE 615 in a second UE-specific RRC configuration. The UE 615 may receive the second SP mode configuration from the BS 605. The second transmit power parameter included in the second SP mode configuration may be, for example, a maximum transmit power specific to the UE 615 or a maximum transmit PSD specific to the UE 615.

[0117] In some instances, the BS 605 may configure a first UL maximum transmit power of the UE 615 for a first transmit power parameter configured for the first SP mode, and may configure a second UL maximum transmit power of the UE 615 for a second transmit power parameter configured for the second SP mode. In some instances, the BS 605 may configure a first UL maximum transmit PSD of the UE 615 for a first transmit power parameter configured for the first SP mode, and may configure a second UL maximum transmit PSD of the UE 615 for a second transmit power parameter configured for the second SP mode.

[0118] In some aspects, the BS 605 may configure a first UL BWP for the first SP mode configuration and may configure a second UL BWP for the second SP mode configuration. The first transmit power parameter may be a first UL maximum transmit power of the UE 615, and the BS 605 may use the first DL maximum transmit power. The second transmit power parameter may be a second UL maximum transmit power of the UE 615, and the BS uses the second DL maximum transmit power. The first DL maximum transmit power may be different from the second DL maximum transmit power. Additionally or alternatively, the first UL BWP for the first SP mode configuration may be different from the second UL BWP for the second SP mode configuration. For example, the first UL BWP and the second UL BWP may include different numbers of frequency bandwidths, and the first transmit power parameter and the second transmit power parameter may indicate the same maximum transmit power of the UE 615.

[0119] In some aspects, the BS 605 may send a first SP-mode configuration by sending a first BWP switching configuration for switching from a second UL BWP to a first UL BWP, wherein the first UL BWP is associated with the first SP-mode configuration and the second UL BWP is associated with the second SP-mode configuration. The first BWP switching configuration may include the first SP-mode configuration. The BS 605 may also send a second SP-mode configuration by sending a second BWP switching configuration for switching from the first UL BWP to the second UL BWP. The second BWP switching configuration may include the second SP-mode configuration.

[0120] In some instances, the BS 605 may include the UL maximum transmit power of the UE 615 in the DCI. For example, the BS 605 may send a first DCI indicating a first power mode configuration (e.g., a first SP mode configuration) to the UE 315, and / or may send a second DCI indicating a second power mode configuration (e.g., a second SP mode configuration) to the UE 315. In one instance, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit power of the UE 315, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit power of the UE 315. In another instance, the first transmit power parameter included in the first power mode configuration may include the first UL maximum transmit PSD of the UE 315, and the second transmit power parameter included in the second power mode configuration may include the second UL maximum transmit PSD of the UE 315.

[0121] In one instance, BS 305 may send a first DCI in a first GC-PDCCH and may send a second DCI in a second GC-PDCCH different from the first GC-PDCCH. In another instance, BS 305 may send a first DCI in a first UE-specific DCI indicating a grant including a set of first bits, and / or may send a second DCI in a second UE-specific DCI indicating a grant including a set of second bits. The DCI grant may indicate a scheduled RB set. If there are unused bits in the RB set indication field, BS 305 may use the unused bits to indicate a first power mode configuration or a second power mode configuration. The set of first bits and / or the set of second bits may indicate whether the first communication signal is transmitted based on the first power mode configuration or the second communication signal is transmitted based on the second power mode configuration, which will be further discussed below with respect to, for example, actions 806 and 808.

[0122] In action 806 of method 800, UE 615 may transmit a first communication signal based on the first SP mode configuration. For example, UE 615 may transmit the first communication signal according to a first transmit power parameter (e.g., maximum transmit power or maximum transmit PSD) included in the first SP mode configuration. For example, UE 615 may configure its transmit power to be approximately 6 dBm lower than the first transmit power parameter. Alternatively, UE 615 may configure its transmit PSD to be approximately 6 dBm / MHz lower than the first transmit power parameter. BS 605 may receive the first communication signal based on the first SP mode configuration from UE 615.

[0123] In action 808 of method 800, UE 615 may transmit a second communication signal based on the second SP mode configuration. For example, UE 615 may transmit the second communication signal according to a second transmit power parameter (e.g., maximum transmit PSD) included in the second SP mode configuration. For example, UE 615 may configure its transmit power to be approximately 6 dBm lower than the second transmit power parameter. Alternatively, UE 615 may configure its transmit PSD to be approximately 6 dBm / MHz lower than the second transmit power parameter. BS 605 may receive a second communication signal based on the second SP mode configuration from UE 615.

[0124] In some aspects, the first and second communication signals may be UL communication signals. For example, the UE 615 may send the first UL communication signal in the first UL BWP based on the first SP mode configuration, and / or may send the second UL communication signal in the second UL BWP based on the second SP mode configuration. The BS 605 may receive the first UL communication signal in the first UL BWP based on the first SP mode configuration, and / or may receive the second UL communication signal in the second UL BWP based on the second SP mode configuration.

[0125] although Figure 8 A first SP configuration and a second SP configuration indicating a first transmit power or PSD of the BS and a second transmit power or PSD of the BS are described, but it should be understood that in other examples, the first SP configuration and the second SP configuration may indicate a first transmit power or PSD of the UE and a second transmit power or PSD of the UE.

[0126] In some aspects, BS 605 can switch between different SP mode configurations for lower PSD. For example, a standard or regulation (e.g., Federal Communications Commission (FCC) regulation) can specify that the maximum transmit PSD of UE 615 should be 6dBm lower than the maximum transmit PSD per MHz of BS 605.

[0127] Fig. 9900 is a subband configuration of a UL PSD according to one or more aspects of the present disclosure. The subband configuration 900 may be composed of, for example, Figure 1 BS 105 and / or UE 115 in Figure 3-Figure 5 BS 305, UE 315a and / or UE 315b, and / or Figure 6-Figure 8 The subband configuration 900 may be used for the worst-case per-subband configuration of the UL PSD. Fig. 9 In the example shown, BS 105 may configure a separate UL PSD for each UL subband. For example, BS 105 may configure PSD 910 for subband 902, PSD 912 for subband 904, PSD 914 for subband 906, and PSD 916 for subband 908. Each of PSDs 910, 912, 914, and 916 may be the same or different from each other. The PSDs may be different depending on the different ULBWPs used.

[0128] Fig.10 1000 of a UL BWP-related configuration of a PSD according to one or more aspects of the present disclosure is shown. The UL BWP-related configuration 1000 may be configured by, for example, Figure 1 BS 105 and / or UE 115 in Figure 3-Figure 5 BS 305, UE 315a and / or UE 315b, and / or Figure 6-Figure 8 Used by BS 605 and / or UE 615.

[0129] exist Fig.10 In the example shown, UL BWP 1001 includes sub-band 1002, sub-band 1004, sub-band 1006, and sub-band 1008. Fig.10 As shown, in some aspects, BS 105 may configure a single PSD 1010 for all subbands 1002, 1004, 1006, and 1008 in UL BWP 1001. The first transmit power parameter included in the first power mode configuration may include a first maximum transmit PSD for UE 115 for all subbands within UL BWP 1001, and the second transmit power parameter included in the second power mode configuration may include a second maximum transmit PSD for UE 115 for all subbands within UL BWP 1001. In some cases, the first power mode configuration includes an SP mode configuration, and the second power mode configuration includes an LP mode configuration. In some instances, the first power mode configuration includes a first SP mode configuration, and the second power mode configuration includes a second SP mode configuration that is different from the first SP mode configuration.

[0130] In other aspects, the BS 105 may configure a single PSD for each subband in the UL BWP 1001 (not shown). The first transmit power parameters included in the first power mode configuration may include a first maximum transmit PSD for a first subband within the first UL BWP and a second maximum transmit PSD for a second subband within the first UL BWP, where the first subband may be different from the first subband. Additionally or alternatively, the second transmit power parameters included in the second power mode configuration may include a third maximum transmit PSD for a third subband within the second UL BWP and a fourth maximum transmit PSD for a fourth subband within the second UL BWP, where the third subband may be different from the fourth subband.

[0131] In some aspects, the BS 105 and the UE 115 may operate in a first subband having an SP mode configuration and may operate in a second subband having an LP mode configuration. In other words, the BS 105 and the UE 115 may operate in an SP mode configuration and an LP mode configuration for different subbands, such as Fig.11 As shown. The wireless communication network 1100 may be incorporated into the network 100. The network 1100 may include a BS 1105 and a UE 1115. The BS 1105 may correspond to Figure 1 BS 105 in, and UE 1115 may correspond to Figure 1 UE 115 in.

[0132] exist Fig.11 In the example shown, the BS 1105 may send a first power mode configuration 1120 associated with the first subband and a second power mode configuration 1122 associated with the second subband to the UE 1115. In some aspects, for each UE, the BS 1105 may dynamically switch between the first power mode configuration 1120 and the second power mode configuration 1122. For example, the BS 1105 may serve the UE 1115 in the first power mode configuration 1120 and the second power mode configuration 1122, and may dynamically switch between the first power mode configuration 1120 and the second power mode configuration 1122 for the UE 1115. Thus, the UE 1115 may determine the transmit power or transmit PSD of its transmission in the first subband based on the first transmit power parameter indicated by the first power mode configuration 1120, and may determine the transmit power or transmit PSD of its transmission in the second subband based on the first transmit power parameter indicated by the second power mode configuration 1122. If the assignment spans multiple subbands, the BS 1105 and UE 1115 may use the minimum PSD across the assigned subbands.

[0133] The BS 1105 may send the first and second power mode configurations to the UE 1115 in various ways. In some aspects, the BS 1105 may send the first power mode configuration 1120 to the UE 1115 by sending a first BWP switching configuration for switching from the second UL BWP to the first UL BWP, and / or may send the second power mode configuration 1122 to the UE 1115 by sending a second BWP switching configuration for switching from the first UL BWP to the second UL BWP. The first BWP switching configuration may include the first power mode configuration 1120, and the second BWP switching configuration may include the second power mode configuration 1122. The UE 1115 may receive the first power mode configuration 1120 and the second power mode configuration 1122 from the BS 1105.

[0134] In some aspects, the BS 1105 may send a first power mode configuration 1120 to the UE 1115 by sending a first power mode configuration 1120 in a first RRC configuration, and / or may send a second power mode configuration 1122 to the UE 1115 by sending a second power mode configuration 1122 in a second RRC configuration. The BS 1105 may configure the power mode configuration for each subband PSD limit. The UE 1115 may apply different PSD limits based on the UL transmission location. The first RRC configuration and / or the second RRC configuration may be BWP-dependent.

[0135] In some aspects, BS 1105 may send a first power mode configuration 1120 to UE 1115 by sending the first power mode configuration 1120 in a first UE-specific RRC configuration, and / or may send a second power mode configuration 1122 by sending the second power mode configuration 1122 in a second UE-specific RRC configuration.

[0136] In some aspects, the BS 1105 may send the first power mode configuration 1120 to the UE 1115 by sending the first power mode configuration 1120 in a first DCI indicating the first power mode configuration, and / or may send the second power mode configuration 1122 to the UE 1115 by sending the second power mode configuration 1122 in a second DCI indicating the second power mode configuration. In one example, the BS 1105 may send the DCI (e.g., the first DCI, the second DCI, etc.) by sending the DCI in the GC-PDCCH. In another example, the BS 1105 may send the DCI (e.g., the first DCI, the second DCI, etc.) by sending the DCI in a UE-specific DCI indicating a grant including a set of bits. The set of bits may indicate to the UE 1115 whether to transmit the first communication signal based on the first power mode configuration 1120 or to transmit the second communication signal based on the second power mode configuration 1122.

[0137] although Fig.11 The SP configuration and LP configuration indicating a first transmit power or PSD of the BS and a second transmit power or PSD of the BS are described, but it should be understood that in other examples, the SP configuration and LP configuration may indicate a first transmit power or PSD of the UE and a second transmit power or PSD of the UE.

The power mode configuration module 1208 and / or the communication module 1209 may be implemented as a processor, a circuit, and / or instructions 1206 stored in the memory 1204 and executed by the processor 1202. In some instances, the power mode configuration module 1208 and / or the communication module 1209 may be integrated within the modem subsystem 1212.
