In one aspect, a wireless device may receive a message including a path loss value and may use an uplink transmit power associated with the received path loss value to send a signal to a UL Rx point. In another aspect, a wireless device may receive a reference signal and a message including an offset value and may use an uplink transmit power, which includes a downlink path loss value associated with the reference signal minus the offset value, to send a signal to a UL Rx point. In another aspect, a base station may obtain a power measurement of a signal from a wireless device and may send to the wireless device a path loss value associated with the received power measurement or an offset value associated with the received power measurement.

Description

[0001] Cross - Reference to Related Applications

[0002] This application claims the benefit of priority of U.S. Provisional Application No. 62 / 994,232, filed on Mar. 24, 2020, entitled “MANAGING TRANSMIT POWER CONTROL”, the entire content of which is incorporated herein by reference for all purposes. Technical Field

[0003] The present disclosure generally relates to wireless devices, and more particularly to enabling wireless devices to manage uplink transmit power. Background Art

[0004] Standards for fifth - generation (5G) new radio (NR) propose the use of millimeter - wave (“mmWave”) communications to expand the communication bandwidth. To provide coverage using the millimeter - wave band, a large number of small cells that communicate with a larger base station (such as a macro cell or node, or a central cell or node) via a backhaul communication link can be densely deployed (sometimes referred to as “densely deployed”). Although the base station has sufficient transmit power to send signals to wireless devices, the transmit power and battery storage of wireless devices may be relatively limited. Thus, some dense deployments can include uplink receive (UL Rx) points to receive signals from wireless devices and pass the received signals to the base station via the backhaul communication link. However, in such a deployment, the wireless device may not receive path - loss information from the UL Rx point, which the wireless device would use to determine the transmit power for signal transmission to the UL Rx point.

[0047] The following description is directed to certain implementations with the intent of describing innovative aspects of the present disclosure. However, those of ordinary skill in the art will readily recognize that the teachings herein can be applied in many different ways.

[0048] The described implementations can be implemented in any device, system, or network capable of transmitting and receiving radio frequency (RF) signals according to any of the Institute of Electrical and Electronics Engineers (IEEE) 16.11 standards or any of the IEEE 802.11 standards. Standards, Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Global System for Mobile Communications (GSM), GSM / General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband CDMA (W-CDMA), Evolution-Data Optimized (EV-DO), 1xEV-DO, EV-DO Revision A, EV-DO Revision B, High Speed Packet Access (HSPA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Evolutionary High Speed Packet Access (HSPA+), Long Term Evolution (LTE), AMPS, or other signals used to communicate within a wireless network, cellular network, or Internet of Things (IoT) network (such as a system utilizing 3G, 4G, or 5G technology or further implementations thereof).

[0049] Various implementations enable a wireless device to manage transmit power control communication with an uplink receive (UL Rx) point. In a dense deployment using a UL Rx point (sometimes referred to as an "uplink dense deployment"), a base station transmits a downlink signal to the wireless device, and the wireless device transmits an uplink signal to the UL Rx point. Since the downlink transmission is from the base station to the wireless device and the uplink transmission is from the wireless device to the UL Rx point, the uplink and downlink are asymmetric in an uplink dense deployment using a UL Rx point. In such a communication system, the wireless device cannot use the downlink reference signal to measure the reference signal, calculate a path loss value, or determine the uplink transmit power based on the calculated path loss. To address this challenge, in various implementations, the base station can be configured to determine a path loss value, a set of path loss values, a path loss offset value, or a set of path loss offset values, and transmit the determined values to the wireless device.

[0050] In various implementations, a device of the wireless device (such as a processor) can receive a message including a path loss value from a base station (e.g., a macro cell, a macro node, a central cell, a central node, or another suitable large base station). The wireless device can use the path loss value to determine, for example, the uplink transmit power for transmission to the UL Rx point. The base station can determine the path loss value based on measurements performed by the UL Rx point on the signal received from the wireless device by the UL Rx point. In some implementations, the UL Rx can perform processing on the uplink signal received from the wireless device before sending the received signal to the base station (in which case the UL Rx point sends the processed uplink signal to the base station). In some implementations, the UL Rx point can perform little or no processing on the received uplink signal before sending the received signal to the base station.

[0051] In some implementations, the path loss value may include a Physical Uplink Shared Channel (PUSCH) path loss value. In some implementations, the path loss value may include a Physical Uplink Control Channel (PUCCH) path loss value. In some implementations, the path loss value may include a Sounding Reference Signal (SRS) path loss value.

[0052] In some implementations, instead of the path loss value, the base station may send and the wireless device may receive an indication (such as an index) of a set of path loss values and an indication of one path loss value in the set of path loss values. In such an implementation, the wireless device may use the indicated path loss value from the set of path loss values to determine the uplink transmit power.

[0053] Various signaling mechanisms may be used to convey the indication of the set of path loss values and the indication of the path loss value in the set. In some implementations, the indication of the set of path loss values may be sent via Radio Resource Control (RRC) signaling or a Medium Access Control (MAC)-Control Element (CE) message. In some implementations, the indication of the PUSCH path loss value may be sent via the Sounding Reference Signal Resource Indicator (SRI) field in a Downlink Control Information (DCI) message. In some implementations, the indication of the PUCCH path loss value may be sent via a MAC-CE message. In some implementations, the indication of the SRS path loss value may be sent via a MAC-CE message.

[0054] In some implementations, the base station may determine an offset value, instead of the path loss value, based on power measurements received from the UL Rx point of a signal from the wireless device, and may send the determined offset value to the wireless device. In such an implementation, the wireless device may use the offset value to adjust the uplink transmit power, e.g., for transmission to the UL Rx point. In some implementations, the offset value may include a PUSCH offset value. In some implementations, the offset value may include a PUCCH offset value. In some implementations, the offset value may include an SRS offset value.

[0055] In some implementations, instead of the offset value, the base station may send and the wireless device may receive an indication (e.g., an index) of a set of offset values and an indication of one offset value in the set of offset values. In such an implementation, the wireless device may use the indicated offset value from the set of offset values to adjust the uplink transmit power.

[0056] Various signaling mechanisms can be used to convey an indication of a set of offset values and an indication of an offset value within the set. In some implementations, an indication of the set of offset values can be sent via RRC signaling or a MAC-CE message. In some implementations, an indication of the PUSCH offset value can be sent via the SRI field in a DCI message. In some implementations, an indication of the PUCCH offset value can be sent via a MAC-CE message. In some implementations, an indication of the SRS offset value can be sent via a MAC-CE message.

[0057] Certain implementations of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. Some implementations can improve the operation of a wireless device and a communication network by enabling the wireless device to select or otherwise determine an uplink transmit power suitable for a device (such as a UL Rx point) to which the wireless device is transmitting. Some implementations can improve the operation of the communication network by enabling a base station to determine path loss information or offset information and provide that information to the wireless device for determining an appropriate uplink transmit power. Dense uplink deployment can enable the wireless device and the communication network to operate more efficiently and can allow the wireless device to conserve battery power by communicating with nearby UL Rx points using lower uplink power. Various implementations can enable the wireless device to determine appropriate uplink power control in a dense uplink deployment. Various implementations can result in a lower-cost communication network in some locations because each UL point in a dense uplink deployment needs to have receiving capabilities as compared to a dense deployment of access points having equipment that serves as both a UL Rx point and a DL Tx point.

[0058] The term "wireless device" is used herein to refer to any one or all of the following: a wireless router device, a radio, a cellular phone, a smart phone, a portable computing device, a personal or mobile multimedia player, a laptop computer, a tablet computer, a smartbook, a ultrabook, a palmtop computer, a wireless email receiver, an Internet-enabled multimedia cellular phone, medical devices and equipment, biosensors / devices, wearable devices (including smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (such as smart rings, smart bracelets, etc.)), entertainment devices (such as wireless game controllers, music and video players, satellite radios, etc.), Internet of Things (IoT) devices enabled for wireless networks (including smart meters / sensors, industrial manufacturing equipment, large and small machines and appliances for home or enterprise use), wireless communication elements within an automated or semi-automated vehicle, wireless devices added or incorporated into various mobile platforms, global positioning system devices, and similar electronic devices including a memory, wireless communication components, and a programmable device (such as a processing system).

[0059] The term "system-on-a-chip" (SOC) is used herein to refer to a single integrated circuit (IC) chip of a device (such as a processing system) that includes multiple resources or processors integrated on a single substrate. A single SOC can include circuitry for digital, analog, mixed-signal, and radio frequency functions. A single SOC can also include any number of general-purpose or special-purpose processors (such as digital signal processors, modem processors, video processors, etc.), memory blocks (e.g., ROM, RAM, flash memory, etc.), and resources (e.g., timers, voltage regulators, oscillators, etc.). Each SOC can also include software for controlling the integrated resources and processors, as well as for controlling peripheral devices.

[0060] The term "system-in-package" (SIP) can be used herein to refer to a single module or package of a device (such as a processing system) that includes multiple resources, computing units, cores or processors on two or more IC chips, substrates, or SOCs. For example, a SIP can include a single substrate on which multiple IC chips or semiconductor dies are stacked in a vertical configuration. Similarly, a SIP can include one or more multi-chip modules (MCMs) in which multiple ICs or semiconductor dies are encapsulated onto a unified substrate. A SIP can also include multiple independent SOCs that are coupled together via high-speed communication circuitry and packaged closely together (such as on a single motherboard or in a single wireless device). The proximity of the SOCs enables high-speed communication as well as sharing of memory and resources.

[0061] The term "processing system" is used herein to refer to a processor, SOC, or SIP that is coupled to or includes a memory device.

[0062] Figure 1 A system block diagram illustrating an example communication system 100 is shown. The communication system 100 can be a 5G NR network or any other suitable network (such as an LTE network).

[0063] The communication system 100 can include a heterogeneous network architecture that includes a core network 140 and various mobile devices ( Figure 1 shown as wireless devices 120a - 120e in the figure). The communication system 100 can also include several base stations (shown as BS110a, BS 110b, BS 110c, and BS 110d) and other network entities. In some implementations, one or more of the base stations (such as 110b, 110c) can be configured to function as uplink receive (UL Rx) points.

[0064] A base station is an entity that communicates with wireless devices (mobile devices) and can also be referred to as NodeB, B node, LTE evolved NodeB (eNB), access point (AP), radio head, transmission and reception point (TRP), new radio base station (NRBS), 5G NodeB (NB), next-generation NodeB (gNB), etc. Each base station can provide communication coverage for a specific geographical area. In 3GPP, the term "cell" can refer to the coverage area of a base station, or the base station subsystem serving that coverage area, or a combination thereof, depending on the context in which the term is used.

[0065] Base stations 110a - 110d can provide communication coverage for macro cells, pico cells, femto cells, another type of cell, or a combination thereof. A macro cell can cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unrestricted access by mobile devices with a service subscription. A pico cell can cover a relatively small geographical area and can allow unrestricted access by mobile devices with a service subscription. A femto cell can cover a relatively small geographical area (e.g., a residence) and can allow restricted access by mobile devices associated with the femto cell (e.g., mobile devices in a closed subscriber group (CSG)). The base station for a macro cell can be referred to as a macro BS. The base station for a pico cell can be referred to as a pico BS. The base station for a femto cell can be referred to as a femto BS or a home BS. In the Figure 1 example shown, base station 110a can be a macro BS for macro cell 102a, base station 110b can be a pico BS for pico cell 102b, and base station 110c can be a femto BS for femto cell 102c. Base stations 110a - 110d can support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" can be used interchangeably herein.

[0066] In some examples, a cell can be non-stationary, and the geographical area of the cell can move according to the location of the mobile base station. In some examples, base stations 110a - 110d can be interconnected with each other and with one or more other base stations or network nodes (not shown) in communication system 100 through various types of backhaul interfaces, such as direct physical connections, virtual networks, or combinations thereof using any suitable transport network.

[0067] Base stations 110a - 110d can communicate with the core network 140 over a wired or wireless communication link 126. Wireless devices 120a - 120e can communicate with base stations 110a - 110d over a wireless communication link 122.

[0068] The wired communication link 126 can use various wired networks (such as Ethernet, TV cable, telephone, fiber optic, and other forms of physical network connections), and these wired networks can use one or more wired communication protocols (such as Ethernet, Point-to-Point Protocol, High-Level Data Link Control (HDLC), Advanced Data Communication Control Protocol (ADCCP), and Transmission Control Protocol / Internet Protocol (TCP / IP)).

[0069] The communication system 100 can also include a relay station (such as relay BS 110d). A relay station is an entity capable of receiving data transmissions from an upstream station (such as a base station or a mobile device) and sending data transmissions to a downstream station (such as a wireless device or a base station). A relay station can also be a mobile device capable of relaying transmissions for other wireless devices. In Figure 1 the example shown, the relay station 110d can communicate with the macro base station 110a and the wireless device 120d to facilitate communication between the base station 110a and the wireless device 120d. A relay station can also be referred to as a relay base station, relay BS, repeater, etc.

[0070] The communication system 100 can be a heterogeneous network including different types of base stations (such as macro base stations, pico base stations, femto base stations, relay base stations, etc.). These different types of base stations can have different transmit power levels, different coverage areas, and different impacts on interference in the communication system 100. For example, a macro base station can have a high transmit power level (such as 5 to 40 watts), while pico base stations, femto base stations, and relay base stations can have lower transmit power levels (such as 0.1 to 2 watts).

[0071] The network controller 130 can be coupled to a set of base stations and can provide coordination and control for these base stations. The network controller 130 can communicate with the base stations via a backhaul. The base stations can also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0072] The wireless devices 120a, 120b, 120c can be dispersed throughout the communication system 100, and each wireless device can be stationary or mobile. A wireless device can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc.

[0073] The macro base station 110a can communicate with the communication network 140 over a wired or wireless communication link 126. The wireless devices 120a, 120b, 120c can communicate with the base stations 110a - 110d over a wireless communication link 122.

[0074] A wired communication link may use various wired networks (such as Ethernet, TV cable, telephone, fiber optic, and other forms of physical network connections), which may use one or more wired communication protocols, such as Ethernet, Point-to-Point Protocol, High-Level Data Link Control (HDLC), Advanced Data Communication Control Protocol (ADCCP), and Transmission Control Protocol / Internet Protocol (TCP / IP).

[0075] Wireless communication links 122, 124 may include multiple carrier signals, frequencies, or frequency bands, each of which may include multiple logical channels. Wireless communication links 122 and 124 may utilize one or more radio access technologies (RATs). Examples of RATs that may be used in a wireless communication link include: 3GPP LTE, 3G, 4G, 5G (e.g., NR), GSM, Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Worldwide Interoperability for Microwave Access (WiMAX), Time Division Multiple Access (TDMA), and other mobile phone communication technology cellular RATs. Further examples of RATs that may be used in one or more of the various wireless communication links 122, 124 within the communication system 100 include medium-range protocols (such as Wi-Fi, LTE-U, LTE-Direct, LAA, MuLTEfire) and relatively short-range RATs (such as ZigBee, Bluetooth, and Bluetooth Low Energy (LE)).

[0076] Certain wireless networks (such as LTE) utilize Orthogonal Frequency Division Multiplexing (OFDM) on the downlink and Single Carrier Frequency Division Multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also often referred to as frequency tones, frequency slots, etc. Each subcarrier can be modulated with data. Generally, modulation symbols are transmitted using OFDM in the frequency domain and SC-FDM in the time domain. The spacing between adjacent subcarriers can be fixed, and the total number (K) of subcarriers can depend on the system bandwidth. For example, the subcarrier spacing can be 15 kHz, and the minimum resource allocation (referred to as a "resource block") can be 12 subcarriers (or 180 kHz). Thus, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal Fast Fourier Transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth can also be divided into subbands. For example, a subband can cover 1.08 MHz (i.e., 6 resource blocks), and for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, there can be 1, 2, 4, 8, or 16 subbands, respectively.

[0077] Although the description of some implementations may use terms and examples associated with LTE technology, some implementations may be applicable to other wireless communication systems (such as New Radio (NR) or 5G networks). NR can utilize OFDM with cyclic prefix (CP) on both the uplink (UL) and downlink (DL), and includes support for half-duplex operation using time division duplex (TDD). A single component carrier bandwidth of 100 MHz can be supported. Nr resource blocks can span 12 subcarriers with a subcarrier bandwidth of 75 kHz over a duration of 0.1 milliseconds (ms). Each radio frame can include 50 subframes with a length of 10 ms. Thus, each subframe can have a length of 0.2 ms. Each subframe can include a link direction for data transmission (i.e., DL or UL), and the link direction of each subframe can be dynamically switched. Each subframe can include DL / UL data as well as DL / UL control data. Beamforming can be supported and the beam direction can be dynamically configured. Multi-input multi-output (MIMO) transmission with precoding can also be supported. The MIMO configuration in the DL can support up to eight transmit antennas (multi-layer DL transmission with up to eight streams) and up to two streams per wireless device. Multi-layer transmission with up to two streams per wireless device can be supported. Aggregation of multiple cells can be supported using up to eight serving cells. Alternatively, NR can support different air interfaces other than the OFDM-based air interface.

[0078] In general, any number of communication systems and any number of wireless networks can be deployed in a given geographical area. Each communication system and wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between communication systems of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0079] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., a base station) allocates resources for communication among some or all of the devices and equipment within the service area or cell of the scheduling entity. The scheduling entity can be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for the scheduled communication, the subordinate entity utilizes the resources allocated by the scheduling entity.

[0080] A base station is not the only entity that can be used as a scheduling entity. In some examples, a wireless device can be used as a scheduling entity to schedule resources for one or more subordinate entities (e.g., one or more other mobile devices). In this example, the wireless device is acting as a scheduling entity, and the other mobile devices utilize the resources scheduled by the wireless device for wireless communication. The wireless device can be used as a scheduling entity in a peer-to-peer (P2P) network, in a mesh network, or in another type of network. In the mesh network example, the mobile devices can optionally communicate directly with each other in addition to communicating with the scheduling entity.

[0081] Thus, in a wireless communication network having scheduled access to time-frequency resources and having a cellular configuration, a P2P configuration, and a mesh configuration, a scheduling entity and one or more subordinate entities can utilize the scheduled resources for communication.

[0082] Figure 2 A component block diagram of an example computing system 200 is shown. Some implementations can be implemented on several single-processor and multi-processor computer systems, including a system-on-chip (SOC) or a system-in-package (SIP).

[0083] Reference Figure 1 and Figure 2 As shown, the example computing system 200 (which can be a SIP in some implementations) includes two SOCs 202, 204 coupled to a clock 206, a voltage regulator 208, and a wireless transceiver 266 configured to transmit wireless communication to and receive wireless communication from a wireless device (e.g., base station 110A) via an antenna (not shown). In some implementations, the first SOC 202 can operate as a central processing unit (CPU) of the wireless device, which executes instructions by performing arithmetic, logical, control, and input / output (I / O) operations specified by the instructions of a software application. In some implementations, the second SOC 204 can operate as a dedicated processing unit. For example, the second SOC 204 can operate as a dedicated 5G processing unit responsible for managing high-capacity, high-speed (e.g., 5 Gbps, etc.), or ultra-high-frequency short-wavelength (e.g., 28 GHz mmWave spectrum, etc.) communication.

[0084] The first SOC 202 may include a digital signal processor (DSP) 210, a modem processor 212, a graphics processor 214, an application processor 216, one or more coprocessors 218 (e.g., vector coprocessors) connected to one or more processors, a memory 220, custom circuitry 222, system components and resources 224, an interconnect / bus module 226, one or more temperature sensors 230, a thermal management unit 232, and a thermal power envelope (TPE) component 234. The second SOC 204 may include a 5G modem processor 252, a power management unit 254, an interconnect / bus module 264, a plurality of mmWave transceivers 256, a memory 258, and various additional processors 260, such as application processors, packet processors, etc.

[0085] Each processor 210, 212, 214, 216, 218, 252, 260 in the device may include one or more cores, and each processor / core may perform operations independently of other processors / cores. For example, the first SOC 202 may include a processor that executes a first type of operating system (e.g., FreeBSD, LINUX, OS X, etc.) and a processor that executes a second type of operating system (e.g., MICROSOFT WINDOWS 10). Additionally, any one or all of the processors 210, 212, 214, 216, 218, 252, 260 may be included as part of a processor cluster architecture (e.g., a synchronous processor cluster architecture, an asynchronous or heterogeneous processor cluster architecture, etc.). In some implementations, any one or all of the processors 210, 212, 214, 216, 218, 252, 260 may be components of a processing system. A processing system generally may refer to a system or series of machines or components that receive input and process the input to produce a set of outputs (which may be passed to other systems or components such as, for example, the first SOC 202 or the second SOC 250). For example, the processing system of the first SOC 202 or the second SOC 250 may refer to a system that includes various other components or subcomponents of the first SoC 202 or the second SoC 250.

[0086] The processing system of the first SOC 202 or the second SOC 250 can interface with other components of the first SOC 202 or the second SOC 250, and can process information (such as inputs or signals) received from other components, output information to other components, and so on. For example, the chip or modem of the first SOC 202 or the second SOC 250 can include a processing system, a first interface for outputting information, and a second interface for receiving information. In some cases, the first interface can refer to the interface between the processing system of the chip or modem and the transmitter, such that the first SOC 202 or the second SOC 250 can transmit the information output from the chip or modem. In some cases, the second interface can refer to the interface between the processing system of the chip or modem and the receiver, such that the first SOC 202 or the second SOC 250 can receive information or signal inputs, and the information can be passed to the processing system. Those of ordinary skill in the art will readily recognize that the first interface can also receive information or signal inputs, and the second interface can also transmit information.

[0087] The first SOC 202 and the second SOC 204 can include various system components, resources, and custom circuits for managing sensor data, analog-to-digital conversion, wireless data transmission, and for performing other specialized operations, such as decoding data packets and processing encoded audio and video signals for presentation in a web browser. For example, the system components and resources 224 of the first SOC 202 can include power amplifiers, voltage regulators, oscillators, phase-locked loops, peripheral bridges, data controllers, memory controllers, system controllers, access ports, timers, and other similar components for supporting processors and software clients operating on a wireless device. The system components and resources 224 or the custom circuits 222 can also include circuits for interfacing with peripheral devices, such as cameras, electronic displays, wireless communication devices, external memory chips, and so on.

[0088] The first SOC 202 and the second SOC 204 can communicate via the interconnect / bus module 250. The various processors 210, 212, 214, 216, 218 can be interconnected via the interconnect / bus module 226 to one or more memory elements 220, system components and resources 224, and custom circuits 222, as well as the thermal management unit 232. Similarly, the processor 252 can be interconnected via the interconnect / bus module 264 to the power management unit 254, the mmWave transceiver 256, the memory 258, and various additional processors 260. The interconnect / bus modules 226, 250, 264 can include reconfigurable logic gate arrays or implement bus architectures (such as CoreConnect, AMBA, etc.). The communication can be provided by advanced interconnects, such as a high-performance on-chip network (NoC).

[0089] The first SOC 202 or the second SOC 204 may also include an input / output module (not shown) for communicating with resources external to the SOC, such as the clock 206 and the voltage regulator 208. Resources external to the SOC, such as the clock 206 and the voltage regulator 208, may be shared by two or more of the internal SOC processors / cores.

[0090] In addition to the example SIP 200 discussed above, various implementations may be implemented in a variety of processing systems, which may include a single processor, multiple processors, multi-core processors, or any combination thereof.

[0091] Figure 3 A component block diagram showing an example of a software architecture 300 including a radio protocol stack for the user and control planes in wireless communication. The software architecture 300 includes a radio protocol stack for the user and control planes in wireless communication between a base station 350 (e.g., base station 110a) and a wireless device 320 (e.g., wireless devices 120a-120e, 200). Refer Figure 1 - Figure 3 , the wireless device 320 may implement the software architecture 300 to communicate with the base station 350 of a communication system (e.g., communication system 100). In various implementations, the layers in the software architecture 300 may form logical connections with corresponding layers in the software of the base station 350. The software architecture 300 may be distributed among one or more processors (e.g., processors 212, 214, 216, 218, 252, 260). Although illustrated for one radio protocol stack, in a multi-SIM (Subscriber Identity Module) wireless device, the software architecture 300 may include multiple protocol stacks, each of which may be associated with a different SIM (e.g., in a dual-SIM wireless communication device, two protocol stacks are respectively associated with two SIMs). Although described below with reference to specific 5G NR communication layers, the software architecture 300 may support any one of a variety of standards and protocols for wireless communication, and / or may include additional protocol stacks that support any one of a variety of wireless communication standards and protocols.

[0092] The software architecture 300 may include a Non-Access Stratum (NAS) 302 and an Access Stratum (AS) 304. The NAS 302 may include functions to support packet filtering, security management, mobility control, session management, and traffic and signaling between the SIM (e.g., SIM 204) of the wireless device and its core network. The AS 304 may include functions and protocols to support communication between the SIM (e.g., SIM 204) and entities (e.g., base stations) of the supported access network. In particular, the AS 304 may include at least three layers (Layer 1, Layer 2, and Layer 3), and each layer may contain various sub-layers.

[0093] In the user and control planes, layer 1 (L1) of AS 304 may be the physical layer (PHY) 306, which may oversee functions capable of transmitting and / or receiving via an air interface by way of a wireless transceiver (such as wireless transceiver 266). Examples of such physical layer 306 functions may include cyclic redundancy check (CRC) attachment, coding blocks, scrambling and descrambling, modulation and demodulation, signal measurement, MIMO, etc. The physical layer may include various logical channels, including the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH).

[0094] In the user and control planes, layer 2 (L2) of AS 304 may be responsible for the link between wireless device 320 and base station 350 over physical layer 306. In various implementations, layer 2 may include a media access control (MAC) sublayer 308, a radio link control (RLC) sublayer 310, a packet data convergence protocol (PDCP) sublayer 312, and a service data adaptation protocol (SDAP) 317 sublayer, each of which forms a logical connection terminating at base station 350.

[0095] In the control plane, layer 3 (L3) of AS 304 may include a radio resource control (RRC) sublayer 3. Although not shown, software architecture 300 may include additional layer 3 sublayers and various upper layers above layer 3. In various implementations, RRC sublayer 313 may provide functions including broadcasting system information, paging, and establishing and releasing RRC signaling connections between wireless device 320 and base station 350.

[0096] In some implementations, SDAP sublayer 317 may provide a mapping between quality of service (QoS) flows and data radio bearers (DRBs). In the downlink, at base station 350, SDAP sublayer 317 may provide a mapping for DL QoS flows to DRBs. In the uplink, at wireless device 120, SDAP sublayer 317 may deliver DL received QoS flows to upper layers. In some implementations, PDCP sublayer 312 may provide uplink functions including multiplexing between different radio bearers and logical channels, sequence number addition, handover data handling, integrity protection, encryption, and header compression. In the downlink, PDCP sublayer 312 may provide functions including sequential delivery of data packets, duplicate data packet detection, integrity verification, decryption, and header decompression.

[0097] On the uplink, the RLC sublayer 310 may provide segmentation and concatenation of upper layer data packets, retransmission of lost data packets, and automatic repeat request (ARQ). On the downlink, the functions of the RLC sublayer 310 may include reordering of data packets to compensate for out-of-order reception, reassembly of upper layer data packets, and ARQ.

[0098] On the uplink, the MAC sublayer 308 may provide functions including multiplexing between logical and transport channels, random access procedures, logical channel prioritization, and hybrid ARQ (HARQ) operations. On the downlink, the MAC layer functions may include channel mapping within a cell, demultiplexing, discontinuous reception (DRX), and HARQ operations.

[0099] Although the software architecture 300 may provide the function of sending data through a physical medium, the software architecture 300 may further include at least one host layer 314 to provide data transmission services to various applications in the wireless device 320. In some implementations, the application-specific functions provided by the at least one host layer 314 may provide an interface between the software architecture and the general-purpose processor 206.

[0100] In some other implementations, the software architecture 300 may include one or more higher logical layers (e.g., transport, session, presentation, application, etc.) that provide host layer functions. For example, in some implementations, the software architecture 300 may include a network layer (e.g., IP layer) where logical connections terminate at an access and mobility function (AMF) or a packet data network (PDN) gateway (PGW). In some implementations, the software architecture 300 may include an application layer where logical connections terminate at another device (e.g., an end-user device, a server, etc.). In some implementations, the software architecture 300 may further include a hardware interface 316 between the physical layer 306 and communication hardware (e.g., one or more radio frequency (RF) transceivers) in the AS 304.

[0101] Figure 4A and Figure 4B A component block diagram showing an example system 400 configured to manage transmit power control. Refer to Figure 1 - Figure 4B FIG., the system 400 may include a wireless device 402 (such as 120a - 120e, 200, 320), a UL Rx point 404 (such as 110b, 110c), and a base station 405 (such as 110a).

[0102] The wireless device 402 may include one or more processors 424 that can be configured by machine-readable instructions 406.

[0108] The receiver / transmitter module 432 may be configured to receive a power measurement of a signal from the wireless device. For example, the receiver / transmitter module 432 may be configured to receive, from the UL Rx point 404, a power measurement performed by the UL Rx point 404 on a signal received by the UL Rx point 404 from the wireless device 402. The receiver / transmitter module 432 may be configured to transmit a signal or message including a path loss value or an offset value to the wireless device 402.

[0109] The path loss determination module 434 may be configured to determine a path loss value based on a power measurement of a signal transmitted by the wireless device 402.

[0110] The offset determination module 436 can be configured to determine an offset value based on power measurements of signals transmitted by the wireless device 402.

[0111] The wireless device 402 and the base station 405 can include electronic storage devices 422, 426, one or more processors 424, 428, or other components. The wireless device 402 and the base station 405 can include communication lines or ports to enable the exchange of information with a network or other computing platforms. The illustration of the wireless device 402 and the base station 405 is not intended to be restrictive, and the wireless device 402 and the base station 405 can include multiple hardware, software, or firmware components that operate together to provide the functions attributed to the wireless device 402 and the base station 405 herein.

[0112] The electronic storage devices 422, 426 can include non-transitory storage media that electronically store information. The storage media of the electronic storage devices 422, 426 can include a system storage device provided integrally (i.e., substantially non-removably) with the wireless device 402 or the base station 405 or one or both of removable storage devices removably connectable to the wireless device 402 or the base station 405 via, for example, ports (such as universal serial bus (USB) ports, FireWire ports, etc.) or drives (such as disk drives, etc.).

The electronic storage devices 422, 426 can store software algorithms, information determined by the processor(s) 424, 428, information received from the wireless device 402, information received from the UL Rx point 404, information received from the base station 405, or other information that enables each device to operate as described herein.

[0114] (Multiple) processors 424, 428 may be configured to provide information processing capabilities in the wireless device 402. Accordingly, (multiple) processors 424, 428 may include one or more of a digital processor, an analog processor, digital circuitry designed to process information, analog circuitry designed to process information, a state machine, or other mechanisms for electronically processing information. Although (multiple) processors 424, 428 are shown as a single entity, this is for illustrative purposes only. In some implementations, processors 424, 428 may include multiple processing units. These processing units may be physically located within the same device, or processors 424, 428 may represent the processing functionality of multiple devices operating in concert. Processors 424, 428 may be configured to execute modules 408-414 and 432-436 or other modules. Processors 424, 428 may be configured to execute modules 408-414 and 432-436 or other modules via software, hardware, firmware, some combination of software, hardware, or firmware, or other mechanisms for configuring processing capabilities on processors 408-414 and 432-436. As used herein, the term "module" may refer to any component or collection of components that performs the functions attributed to the module. This may include one or more physical processors, processor-readable instructions, circuitry, hardware, storage media, or any other component during the execution of processor-readable instructions.

[0115] The descriptions of the functions provided by the various modules 408-414 and 432-436 described below are for illustrative purposes and are not intended to be limiting, as any one of modules 408-414 and 432-436 may provide more or less functionality than described. For example, one or more of modules 408-414 and 432-436 may be removed, and some or all of their functionality may be provided by other modules among modules 408-414 and 432-436. As another example, (multiple) processors 408-414 and 432-436 may be configured to execute one or more additional modules that may perform some or all of the functions attributed to one of modules 408-414 and 432-436 below.

[0116] Figure 4C A signal flow diagram 450 illustrating an example method for managing transmit power control is shown. Refer to Figure 1 - Figure 4C , signal flow diagram 450 shows a generalized signal flow, the details of which are further described below ( Figure 5A - Figure 8E ).

[0117] In various implementations, as part of an initial access procedure, a base station 456 (such as base stations 110a, 350, 405) may transmit a downlink reference signal 458 that can be received by a wireless device 452 (such as wireless devices 120a - 120e, 200, 320, 402).

[0118] The wireless device may use the transmit power based on the downlink reference signal 458 from the base station to transmit a signal 460 for initial access communication to the base station.

[0119] The wireless device 452 and the base station 456 may establish a communication session 462 after successfully performing the initial access procedure.

[0120] Thereafter, the wireless device 452 may transmit an uplink signal 464 that is received by a UL Rx point 454 (such as UL Rx points 110b, 110c, 404). In various implementations, the reception of the uplink signal 464 by the UL Rx point 454 (as opposed to being received by the base station 456) may be transparent to the wireless device 452.

[0121] In operation 466, the UL Rx point 454 may perform a power measurement on the received uplink signal 464. In some implementations, the UL Rx point 454 may optionally perform processing on the received uplink signal 464.

[0122] The UL Rx point 454 may provide a message 468 to the base station 456 that includes a power measurement of the received uplink signal.

[0123] Based on the power measurement received by the base station 456 from the UL Rx point 454, the base station 456 may determine or calculate, in operation 470, a value or set of values to send to the wireless device 452 such that the wireless device 452 can determine the uplink transmit power.

[0124] The base station 456 may send the determined or calculated value, or an indication of the set of values, and an indication of the value from the set of values to the wireless device in a message 472. In some implementations, the value may include a path loss value. In some implementations, the value may include a set of path loss values, and an indication of the value from the set of path loss values. In some implementations, the wireless device 452 may determine the uplink transmit power based on the path loss value or the indicated path loss value from the set of path loss values. In some implementations, the value may include an offset value. In some implementations, the value may include a set of offset values, and an indication of the offset value from the set of offset values. In some implementations, the wireless device 452 may adjust the uplink transmit power based on the offset value or the indicated offset value from the set of offset values.

[0125] In operation 474, the wireless device 452 may determine the uplink transmit power based on the path loss value or may adjust the uplink transmit power based on an offset value.

[0126] In operation 476, the wireless device 452 may use the determined or adjusted transmit power to transmit a signal 464 to the UL Rx point 454.

[0129] In block 504, the means may transmit a signal to the UL Rx point using an uplink transmit power associated with the received path loss value. For example, the means may determine the uplink transmit power of the signal to be transmitted to the UL Rx point in view of (or otherwise based on) the path loss value received from the base station, the uplink transmit power being suitable for ensuring uplink reception, and then use the uplink transmit power when transmitting the signal to the UL Rx point, as described herein with reference Figure 5B - Figure 5F as described. The unit for performing the function of the operation in block 502 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424).

[0137] The device may perform the operations of block 502 ( Figure 5A ).

[0138] Refer to Figure 5E , in block 512, the device may receive an indication of a set of path loss values and an indication of one path loss value in the set of path loss values. In some implementations, the device may receive a message (such as an index) including an indication of a set of path loss values (such as from the base station) instead of a single path loss value. In some implementations, one or more sets of path loss values may be stored in the memory of the wireless device, and each set of path loss values may be associated with an index value. In some implementations, the message may also indicate which path loss value in the set of path loss values the wireless device may use. The components for performing the functions of the operations in block 512 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424) coupled to a wireless transceiver (such as wireless transceiver 266).

[0139] In some implementations, the device may receive an indication of a set of path loss values via one of radio resource control (RRC) signaling or a medium access control (MAC)-control element (CE) message. In some implementations, for PUSCH, the set may be configured via RRC signaling or a MAC-CE message. In some implementations, for PUCCH, or for SRS, the set may be configured via RRC signaling.

[0140] In some implementations, the indication of one path loss value in the path loss value set may include an indication of the PUSCH path loss value via a sounding reference signal resource indicator (SRI) field in a downlink control information (DCI) message. In some implementations, the indication of one path loss value in the path loss value set may include an indication of the PUCCH path loss value via a MAC-CE message. In some implementations, the indication of one path loss value in the path loss value set may include an indication of the SRS path loss value via a MAC-CE message.

[0141] In block 514, the device may transmit a signal to the UL Rx point using an uplink transmit power associated with the received indication of the path loss value set and the received indication of one path loss value in the path loss value set. For example, the device may determine an uplink transmit power suitable for ensuring uplink reception in view of (or otherwise based on) the path loss value within the path loss value set that corresponds to the received indication of one path loss value in the path loss value set. Components for performing the functions of the operations in block 514 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424).

[0142] The device may continuously or periodically repeat operation 500e.

[0143] Reference Figure 5F , after the operation of block 504 ( Figure 5A ), the device may transmit a signal to the UL Rx point using a determined uplink transmit power associated with the received path loss value (such as the PUSCH path loss value, the PUCCH path loss value, or one or more of the PUCCH path loss values received from the base station in block 516) or determined based on the received path loss value. Components for performing the functions of the operations in block 516 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424) coupled to a wireless transceiver (such as wireless transceiver 266).

[0144] Then, the device may perform the operation of block 502 ( Figure 5A ).

[0145] Reference Figure 5G, before performing the operation of block 502, in block 518, the device may use the transmit power associated with the downlink reference signal from the base station to send a signal for initial access communication to the base station. For example, for random access channel (RACH) procedure transmission, or for PUSCH transmission scheduled by a random access response (RAR) uplink grant, the wireless device may not use the path loss value from the base station to determine the uplink transmit power. Instead, for initial access communication, the device may use the information or signal strength in another signal received from the base station (e.g., a downlink reference signal (RS) associated with a physical RACH (PRACH) transmission from the base station) to determine the uplink transmit power.

[0146] Then, the device may perform the operation of block 502( Figure 5A ).

Refer to Figure 1 - Figure 6A , the operations of method 600a may be performed by a device (such as a processing system) (such as 210, 212, 214, 216, 218, 252, 260, 424) of a wireless device (such as wireless devices 120a - 120e, 200, 320, 402).

The components for performing the function of the operation in block 601 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424) coupled to a wireless transceiver (such as wireless transceiver 266).

[0149] In block 602, the device may estimate the downlink path loss value, for example, by comparing the signal strength of the received reference signal with a known value of the transmitted strength reference signal to estimate the signal strength difference. In some implementations, the device may determine the downlink path loss value. The components for performing the function of the operation in block 602 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424).

[0150] In block 603, the device may receive a message including an offset value from the base station, and the device may add or subtract the offset value from a reference power level to select or otherwise determine an appropriate value for the uplink power level. In some implementations, the device may receive a message including an offset value from the base station, and the offset value may be a value in decibels (dB). The wireless device may be directly indicated in the message together with the offset value. Thus, in such implementations, the offset value may not be communicated via the transmission of the DL RS of the wireless device that measures the DL RS. The wireless device may be provided with a DL RS, and the offset value may be applied by the wireless device to the received DL RS to determine the adjustment to be made to the uplink transmit power. In some implementations, the device may receive a downlink reference signal including path loss information from the base station. In some implementations, the downlink reference signal may include an offset value. The components for performing the functions of the operations in block 603 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424) coupled to a wireless transceiver (such as wireless transceiver 266).

[0151] In block 604, the device may determine the uplink transmit power by subtracting the received offset value from the estimated downlink path loss value. For example, the device may adjust the uplink transmit power of the signal to be sent to the ULRx point based on the offset value received from the base station. In some implementations, in block 604, the wireless device may measure the DL RS received from the base station to determine a reference path loss value "PL0". Then, the device may add or subtract the offset value (referred to as the path loss offset or "PLoffset") received from the base station in block 602 from the reference path loss value PL0 to determine the correct power level for the uplink to the current UL Rx point. In equation form, this may be expressed as TX power = PL0 - PLoffset. The components for performing the functions of the operations in block 604 may include a processor (such as 210, 212, 214, 216, 218, 252, 260, 424).
