Description

Technical Field

[0001] In summary, aspects of this disclosure relate to wireless communication systems, and more specifically, aspects of this disclosure relate to multiple transmit / receive point (TRP) communication. Certain embodiments of the techniques discussed below can implement and provide a total transmit power (TTP) indication and / or quasi-co-location (QCL) indication for automatic gain control determination for side-link channel communication. Background Technology

[0002] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, and broadcasting. These wireless networks can be multiple-access networks capable of supporting multiple users by sharing available network resources. Such networks (which are typically multiple-access networks) support communication for multiple users by sharing available network resources.

[0003] A wireless communication network may include multiple base stations or nodes B capable of supporting communication for multiple user equipments (UEs). UEs may communicate with base stations via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the base station to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the base station.

[0004] The base station can send data and control information to the UE on the downlink and / or receive data and control information from the UE on the uplink. On the downlink, transmissions from the base station may encounter interference from transmissions from neighboring base stations or from other radio frequency (RF) transmitters. On the uplink, transmissions from the UE may encounter interference from uplink transmissions from other UEs communicating with neighboring base stations or from other RF transmitters. This interference can degrade performance on both the downlink and uplink.

[0005] As the demand for mobile broadband access continues to grow, the likelihood of network interference and congestion increases with more user devices (UEs) accessing long-range wireless communication networks and the deployment of more short-range wireless systems in communities. Research and development continue to drive the advancement of wireless technologies, not only to meet the ever-growing demand for mobile broadband access but also to improve and enhance the user experience of mobile communications.

[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 limit the scope of this disclosure. Specifically, the detailed description includes particular details for the purpose of providing a thorough understanding of the subject matter of the invention. It will be apparent to those skilled in the art that these particular details are not necessary in every case, and that in some instances, well-known structures and components are shown in block diagram form for clarity.

[0035] In summary, this disclosure relates to providing or participating in communication between two or more wireless devices in one or more wireless communication systems (also referred to as wireless communication networks). In various embodiments, the techniques and apparatus described 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, GSM networks, 5th Generation (5G) or New Radio (NR) networks (sometimes referred to as “5G NR” networks / systems / devices), and other communication networks. As described herein, the terms “network” and “system” are used interchangeably.

[0036] For example, CDMA networks can implement radio technologies such as Universal Terrestrial Radio Access (UTRA) and CDMA2000. UTRA includes Wideband CDMA (WCDMA) and Low Code Rate (LCR). CDMA2000 covers the IS-2000, IS-95, and IS-856 standards.

[0037] For example, TDMA networks can implement radio technologies such as GSM. 3GPP defines the standard (also referred to as GERAN) for the GSM EDGE (Enhanced Data Rate for GSM Evolution) radio access network. The GERAN, along with the network connecting base stations (e.g., Ater and Abis interfaces) and base station controllers (A interface, etc.), is the radio component of GSM / EDGE. The radio access network represents the component of a GSM network through which telephone calls and packet data are routed from the Public Switched Telephone Network (PSTN) and the Internet to the user's mobile phone (also referred to as the user terminal or user equipment (UE)) and from the user's mobile phone to the PSTN and the Internet. A mobile phone operator's network may include one or more GREANs; in the case of UMTS / GSM networks, the GERAN may be coupled with the Universal Terrestrial Radio Access Network (UTRAN). Operator networks may also include one or more LTE networks and / or one or more other networks. Different network types may use different radio access technologies (RATs) and radio access networks (RANs).

[0038] OFDMA networks can implement radio technologies such as Evolved UTRA (E-UTRA), IEEE 802.11, IEEE 802.16, IEEE 802.20, and Flash OFDM. UTRA, E-UTRA, and GSM are part of the Universal Mobile Telecommunications System (UMTS). Specifically, Long Term Evolution (LTE) is a version of UMTS using E-UTRA. UTRA, E-UTRA, GSM, UMTS, and LTE are described in documents from an organization called the 3rd Generation Partnership Project (3GPP), and cdma2000 is described in documents from an organization called 3rd Generation Partnership Project 2 (3GPP2). These various radio technologies and standards are either known or under development. For example, the 3rd Generation Partnership Project (3GPP) is a collaboration among telecommunications associations aimed at defining globally applicable third-generation (3G) mobile phone specifications. 3GPP Long Term Evolution (LTE) is a 3GPP initiative aimed at improving the Universal Mobile Telecommunications System (UMTS) mobile phone standard. 3GPP can define specifications for next-generation mobile networks, mobile systems, and mobile devices. This disclosure relates to the evolution of wireless technologies from LTE, 4G, 5G, NR, and beyond in situations where networks share access to the radio spectrum using new and different sets of radio access technologies or radio air interfaces.

[0039] 5G networks are expected to enable diverse deployments, diverse spectrum, and diverse services and devices using a unified OFDM-based air interface. To achieve these goals, in addition to developing new radio 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 for: (1) massive Internet of Things (IoT) coverage, which has ultra-high density (e.g., ~1M nodes / km). 2 (1) Ultra-low complexity (e.g., ~10 s bits / second), ultra-low energy (e.g., ~10+ years of battery life), and deep coverage with the ability to reach challenging locations; (2) Including mission-critical control with strong security for protecting sensitive personal, financial, or confidential information, ultra-high reliability (e.g., ~99.9999% reliability), ultra-low latency (e.g., ~1 ms), and wide range of users with or without mobility; and (3) With enhanced mobile broadband, including extremely high capacity (e.g., ~10 Tbps / km). 2 Extreme data rates (e.g., multi-Gbps rates, 100+ Mbps user experience rates) and depth awareness with improved discovery and optimization.

[0040] 5G NR devices, networks, and systems can be implemented using optimized OFDM-based waveform characteristics. These characteristics can include: scalable digital schemes and transmission time intervals (TTI); a common, flexible framework to efficiently multiplex services and features using dynamic, low-latency Time Division Duplex (TDD) / Frequency Division Duplex (FDD) designs; and improved radio technologies such as massive MIMO, robust millimeter-wave (mmWave) transmission, advanced channel coding, and device-centric mobility. The scalability of the digital schemes in 5G NR (with scaling of subcarrier spacing) can efficiently address the operation of different services across different spectrums and deployments. For example, in various outdoor and macro coverage deployments implemented with FDD / TDD below 3 GHz, subcarrier spacing can occur at 15 kHz over bandwidths such as 1, 5, 10, and 20 MHz. For other various outdoor and small cell coverage deployments with TDD above 3 GHz, subcarrier spacing can occur at 30 kHz over an 80 / 100 MHz bandwidth. For various other indoor broadband implementations using TDD on the unlicensed portion of the 5 GHz band, subcarrier spacing can occur at 60 kHz over a 160 MHz bandwidth. Finally, for various deployments utilizing mmWave components of TDD at 28 GHz, subcarrier spacing can occur at 120 kHz over a 500 MHz bandwidth.

[0041] 5G NR's scalable digital schemes facilitate scalable Time Intervals (TTIs) for varying 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 begin at symbol boundaries. 5G NR also anticipates self-contained integrated subframe designs where uplink / downlink scheduling information, data, and acknowledgments are contained within the same subframe. Self-contained integrated subframes support communication in unlicensed or contention-based shared spectrum, and adaptive uplink / downlink (which can be flexibly configured per cell to dynamically switch between uplink and downlink to meet current service demands).

[0042] For clarity, certain aspects of the apparatus and technology may be described below with reference to exemplary LTE implementations or in an LTE-centric manner, and LTE terminology may be used as illustrative examples in various sections described below; however, this description is not intended to be limited to LTE applications. In fact, this disclosure relates to shared access to radio spectrum between networks using different radio access technologies or radio air interfaces (such as those of 5G NR).

[0043] Furthermore, it should be understood that, in operation, wireless communication networks adapted according to the concepts herein can operate using any combination of licensed or unlicensed spectrum, depending on load and availability. Therefore, it will be apparent to those skilled in the art that the systems, apparatuses, and methods described herein can be applied to other communication systems and applications besides the specific examples provided.

[0044] While aspects and embodiments are described herein by way of example, those skilled in the art will understand that additional implementations and use cases may occur in many different arrangements and scenarios. The innovations described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and package arrangements. For example, embodiments and / or uses may be implemented via integrated chip embodiments and / or other devices based on non-modular components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may be specific or not specifically targeted at a use case or application, a wide variety of applicability to the described innovations is possible. The range of implementations can be from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or OEM devices or systems that integrate one or more described aspects. In some practical settings, devices integrating the described aspects and features may also necessary include additional components and features for implementing and carrying out the claimed and described embodiments. The intention is that the innovations described herein can be implemented in a wide variety of ways, including large / small devices with different sizes, shapes and structures, chip-level components, multi-component systems (e.g., RF chains, communication interfaces, processors), distributed layouts, end-user devices, etc.

[0045] Figure 1 illustrates a wireless network 100 for communication according to some embodiments. The wireless network 100 may include, for example, a 5G wireless network. As those skilled in the art will understand, the components appearing in Figure 1 may have corresponding counterparts in other network arrangements, including, for example, cellular network arrangements and non-cellular network arrangements (e.g., device-to-device, peer-to-peer, or self-organizing network arrangements, etc.).

[0046] The wireless network 100 shown in Figure 1 includes multiple base stations 105 and other network entities. Base stations can be stations communicating with UEs and can also be referred to as evolved Node Bs (eNBs), next-generation eNBs (gNBs), access points, etc. Each base station 105 can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" can refer to that specific geographic coverage area of ​​a base station and / or a base station subsystem serving that coverage area, depending on the context in which the term is used. In the implementation of the wireless network 100 herein, base stations 105 can be associated with the same or different operators (e.g., the wireless network 100 may include multiple operator wireless networks) and can use one or more frequencies (e.g., one or more bands of licensed spectrum, unlicensed spectrum, or combinations thereof) from the same frequencies as neighboring cells to provide wireless communication. In some examples, a single base station 105 or UE 115 can be operated by more than one network operating entity. In other examples, each base station 105 and UE 115 can be operated by a single network operating entity.

[0047] Base stations can provide communication coverage for macrocells or small cells (such as picocells or femtocells) and / or other types of cells. Macrocells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions to a network provider. Small cells (such as picocells) will typically cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions to a network provider. Small cells (such as femtocells) will also typically cover a relatively small geographic area (e.g., residential areas) and, in addition to unrestricted access, can provide restricted access by UEs associated with the femtocell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in a residential area, etc.). A base station used for macrocells may be referred to as a macro base station. A base station used for small cells may be referred to as a small cell base station, picocell, femtocell, or femtocell base station. In the example shown in Figure 1, base stations 105d and 105e are conventional macro base stations, while base stations 105a-105c are macro base stations implemented using one of 3D MIMO, full-dimensional (FD) MIMO, or massive MIMO. Base stations 105a-105c utilize their higher-dimensional MIMO capabilities to employ 3D beamforming in both elevation and azimuth beamforming to increase coverage and capacity. Base station 105f is a small cell base station, which can be a home node or a portable access point. A base station can support one or more (e.g., two, three, four, etc.) cells.

[0048] Wireless Network 100 can support synchronous or asynchronous operation. For synchronous operation, base stations can have similar frame timings, and transmissions from different base stations can be approximately time-aligned. For asynchronous operation, base stations can have different frame timings, and transmissions from different base stations can be time-disaligned. In some scenarios, the network can be enabled or configured to handle dynamic switching between synchronous and asynchronous operation.

[0049] UE 115 is distributed throughout the wireless network 100, and each UE can be stationary or mobile. It should be recognized that although mobile devices are generally referred to as User Equipment (UE) in standards and specifications published by the 3rd Generation Partnership Project (3GPP), such devices can also be referred to by those skilled in the art as mobile station (MS), user station, mobile unit, user unit, radio unit, remote unit, mobile device, radio device, wireless communication device, remote device, mobile user station, access terminal (AT), mobile terminal, radio terminal, remote terminal, handphone, terminal, user agent, mobile client, client, gaming device, augmented reality device, vehicle component device / module, or any other suitable term. Within this document, a “mobile” device or UE does not necessarily need to be mobile and can be stationary. Some non-limiting examples of mobile devices include embodiments that may include one or more of those in UE 115, including mobile cellular phones, smartphones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, laptop computers, personal computers (PCs), notebook computers, netbooks, smartbooks, tablet computers, and personal digital assistants (PDAs). Mobile devices can also be “Internet of Things” (IoT) or “Internet of Everything” (IoE) devices, such as automobiles or other vehicles, satellite radio units, Global Positioning System (GPS) devices, logistics controllers, drones, multi-wing aircraft, quadcopters, smart energy or security devices, solar panels or solar arrays, municipal lighting, water supply or other infrastructure; industrial automation and enterprise equipment; consumer and wearable devices, such as glasses, wearable cameras, smartwatches, health or fitness trackers, mammalian implantable devices, posture tracking devices, medical devices, digital audio players (e.g., MP3 players), cameras, game consoles, etc.; and digital home or smart home devices, such as home audio, video and multimedia equipment, appliances, sensors, vending machines, smart lighting, home security systems, smart meters, etc. In one aspect, the UE can be a device that includes a Universal Integrated Circuit Card (UICC). In another aspect, the UE 115 can be a device that does not include a UICC. In some aspects, a UE that does not include a UICC can also be referred to as an IoE device. In the embodiments shown in Figure 1, UEs 115a-115d are examples of mobile smartphone-type devices accessing wireless network 100. UEs can also be machines specifically configured for connected communications (including machine-type communication (MTC), enhanced MTC (eMTC), narrowband IoT (NB-IoT), etc.). UEs 115e-115k shown in Figure 1 are examples of various machines configured for communication to access wireless network 100.

[0050] Mobile devices (such as UE 115) are capable of communicating with any type of base station (whether macro base station, pico base station, femto base station, repeater, etc.). In Figure 1, lightning (e.g., communication links) indicates radio transmissions between the UE and a serving base station (which is designated to serve the UE on the downlink and / or uplink), or desired transmissions between base stations, and backhaul transmissions between base stations. In some scenarios, the UE may operate as a base station or other network node. Backhaul communication between base stations of wireless network 100 may occur using wired and / or wireless communication links.

[0051] In operation at wireless network 100, base stations 105a-105c use 3D beamforming and cooperative spatial technologies (such as Cooperative Multipoint (CoMP) or Multi-Connection) to serve UEs 115a and 115b. Macro base station 105d performs backhaul communication with base stations 105a-105c and the small cell (base station 105f). Macro base station 105d also transmits multicast services customized 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 Amber Alerts or Grey Alerts).

[0052] The wireless network 100 in each embodiment supports mission-critical communication for mission-critical devices (such as UE 115e, which is a drone) using highly reliable and redundant links. Redundant communication links with UE 115e include those from macro base stations 105d and 105e and from small cell base station 105f. Other machine-type devices (such as UE 115f (thermometer), UE 115g (smart meter), and UE 115h (wearable device)) can communicate directly with base stations (such as small cell base station 105f and macro base station 105e) via the wireless network 100, or in a multi-hop configuration by communicating with another user device that relays its information to the network (e.g., UE 115f transmits temperature measurement information to the smart meter (UE 115g), and the temperature measurement information is subsequently reported to the network via small cell base station 105f). Wireless network 100 can also provide additional network efficiency through dynamic, low-latency TDD / FDD communication, such as in vehicle-to-vehicle (V2V) mesh networks between UEs 115i-115k communicating with macro base station 105e.

[0053] Figure 2 shows a block diagram of the design of base station 105 and UE 115 (which can be any of the base stations and UEs in Figure 1). For restricted association scenarios (as mentioned above), base station 105 can be small cell base station 105f in Figure 1, and UE 115 can be UE 115c or 115D operating in the service area of ​​base station 105f. UE 115c or 115D will be included in the list of accessible UEs for small cell base station 105f in order to access small cell base station 105f. Base station 105 can also be some other type of base station. As shown in Figure 2, base station 105 can be equipped with antennas 234a to 234t, and UE 115 can be equipped with antennas 252a to 252r to facilitate wireless communication.

[0054] At base station 105, transmit processor 220 can receive data from data source 212 and control information from controller / processor 240. The control information can be used for Physical Broadcast Channel (PBCH), Physical Control Format Indicator Channel (PCFICH), Physical Hybrid ARQ (Automatic Repeat Request) Indicator Channel (PHICH), Physical Downlink Control Channel (PDCCH), Enhanced Physical Downlink Control Channel (EPDCCH), MTC Physical Downlink Control Channel (MPDCCH), etc. Data can be used for PDSCH, etc. Transmit processor 220 can process (e.g., encoding and symbol mapping) data and control information separately to obtain data symbols and control symbols. Transmit processor 220 can also generate reference symbols, for example, for primary synchronization signal (PSS) and secondary synchronization signal (SSS) and cell-specific reference signal. Transmit (TX) Multiple-Input Multiple-Output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols (if applicable) and can provide output symbol streams to modulators (MOD) 232a to 232t. Each modulator 232 can (e.g., for OFDM, etc.) process the corresponding output symbol stream to obtain an output sample stream. Each modulator 232 can additionally or alternatively process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a to 232t can be transmitted via antennas 234a to 234t, respectively.

[0055] At UE 115, antennas 252a to 252r can receive downlink signals from base station 105 and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the corresponding received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain the received symbols from demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 115 to data sink 260, and provide decoded control information to controller / processor 280.

[0056] On the uplink, at UE 115, the transmitting processor 264 can receive and process data from data source 262 (e.g., for the Physical Uplink Shared Channel (PUSCH)) and control information from controller / processor 280 (e.g., for the Physical Uplink Control Channel (PUCCH)). The transmitting processor 264 can also generate reference symbols for reference signals. Symbols from the transmitting processor 264 can be pre-encoded (if applicable) by the TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for SC-FDM, etc.), and transmitted to base station 105. At base station 105, the uplink signal from UE 115 can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiving processor 238 to obtain decoded data and control information transmitted by UE 115. Processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240.

[0057] Controllers / processors 240 and 280 can respectively direct operations at base station 105 and UE 115. Controller / processor 240 and / or other processors and modules at base station 105, and / or controller / processor 280 and / or other processors and modules at UE 115, can perform or direct the execution of various processes used in the techniques described herein, such as performing or directing the execution of other processes shown in Figures 7 and 8 and / or used in the techniques described herein. Memory 242 and 282 can respectively store data and program code for base station 105 and UE 115. Scheduler 244 can schedule the UE to perform data transmission on the downlink and / or uplink.

[0058] Wireless communication systems operated by different network operating entities (e.g., network operators) can share spectrum. In some instances, a network operating entity can be configured to use the entire designated shared spectrum for at least a certain time period before another network operating entity uses the entire designated shared spectrum for a different time period. Therefore, in order to allow network operating entities to use the entire designated shared spectrum and to mitigate interference communications between different network operating entities, certain resources (e.g., time) can be partitioned and allocated to different network operating entities for certain types of communication.

[0059] For example, certain time resources can be allocated to a network operating entity, reserved for exclusive communication by that entity using the entire shared spectrum. Other time resources can also be allocated to a network operating entity, in which the entity is given higher priority than other network operating entities for using the shared spectrum for communication. These time resources, preferentially allocated to a network operating entity, can be used by other network operating entities on an opportunistic basis if the prioritized network operating entity does not utilize these resources. Additional time resources can be allocated for opportunistic use by any network operator.

[0060] Access to shared spectrum and arbitration of time resources between different network operating entities can be centrally controlled by a single entity, autonomously determined by a predefined arbitration scheme, or dynamically determined based on the interaction between wireless nodes of the network operator.

[0061] In some cases, UE 115 and base station 105 may operate in a shared radio frequency spectrum band, which may include licensed or unlicensed (e.g., contention-based) spectrum. In the unlicensed frequency portion of the shared radio frequency spectrum band, UE 115 or base station 105 may conventionally perform a media sensing procedure to compete for access to that spectrum. For example, UE 115 or base station 105 may perform a Listen-Before-Speak (LBT) procedure (e.g., Clear Channel Assessment (CCA)) before communication to determine whether a shared channel is available. CCA may include an energy detection procedure to determine if any other active transmissions are present. For example, the device may infer that a change in the received signal strength indicator (RSSI) of the power meter indicates that the channel is occupied. Specifically, a signal power concentrated in a certain bandwidth and exceeding a predetermined noise floor may indicate another wireless transmitter. CCA may also include the detection of a specific sequence used to indicate channel usage. For example, another device may send a specific preamble before transmitting a data sequence. In some cases, the LBT process may include: the wireless node adjusting its own backoff window based on the amount of energy detected on the channel and / or the ACK / NACK feedback sent by itself as a proxy for collisions.

[0062] Figures 3A-3D illustrate schematic diagrams related to Automatic Gain Control (AGC) and multiple Transmit / Receive Points (TRPs) operation. Referring to Figure 3A, Figure 3A shows an example schematic diagram 300 for AGC prediction for a single transmitting device with a single antenna port / TRP. Referring to Figure 3A, schematic diagram 300 shows a transmission timing diagram for two time slots. In the first time slot (time slot n), the transmitting device (TX UE1) transmits a transmission to the receiving device. This transmission includes a control portion and a data portion. The control portion includes an indication for resource reservations for future time slots, such as the second time slot (time slot m). The receiving device determines the receiving power for the second time slot (e.g., correlates it) based on the received power in the first time slot. For example, the receiving device can use the same gain it determined for the first time slot / during the first time slot. Since no other transmissions are transmitted during the second time slot, and no changes in received power occur (e.g., due to mobility and / or transmit power from the TX device), the received gain determined by AGC results in an accurate AGC prediction for the second time slot. For such a successful / accurate AGC prediction, the receiving device may not need to use or adjust the low-noise amplifier (LNA) gain, or it may use or adjust a smaller LNA gain during the second time slot. As an illustration, the first portion of the second time slot (slot n) (e.g., the previous portion dedicated to AGC operation that occurs during / before the control portion of time slot n) can be configured for data transmission and / or operation. Additional equipment and / or antenna ports / TRPs complicate this AGC prediction, as do variations in transmit power and / or mobility. The upper curve shows the control indication from time slot n for resource reservations in future time slots (such as time slot m). The lower straight line indicates the total received power in time slot m (which follows time slot n) relative to time slot n. In the example of Figure 3A, TX UE1 is the only transmitting device, and therefore, the receiving UE can use the same gain for time slot m as determined in time slot n.

[0063] Referring to Figure 3B, which illustrates an example schematic diagram 310 of multiple devices in a network, the receiving device receives transmissions from up to three transmitting devices in each time slot. Furthermore, because the transmitting devices are located at different locations at different distances, the receiving device can receive transmissions with different receive powers.

[0064] Referring to Figure 3C, Figure 3C is an example schematic diagram 320 of AGC prediction for multiple transmitting devices (such as the device in Figure 3B) with a single antenna. Referring to Figure 3C, schematic diagram 320 illustrates a transmission timing diagram for two time slots. In the first time slot (time slot n), the first transmitting device (TX UE1) transmits a transmission to the receiving device (RX UE). This transmission includes a control portion and a data portion. The control portion includes an indication for resource reservations for future time slots (such as the second time slot (time slot m)). The receiving device may attempt to determine the receiving power for the second time slot (time slot m) based on the received power in the first time slot (time slot n) (e.g., correlate it). However, the receiving device is also scheduled for transmissions from additional devices in the second time slot. If the UE does not know its transmit power and / or cannot accurately predict its transmit power, this additional transmission may lead to inaccurate AGC operation and the resulting receiver gain value. The two lower lines indicate that AGC settings can be used at the beginning of each time slot, as the total received power in the time slot may vary (e.g., from previous time slots). Whether the LNA gain is used for AGC operation can depend on the default gain used at the beginning of the time slot.

[0065] For example, a receiving device might need to adjust its previously determined gain for the first time slot / during the first time slot based on the transmit power of one or more of the second and third transmitting devices for the second time slot. As an example, if the receiving device knows the transmit power of the other transmitting devices, it can perform AGC operations for all (three) transmitting devices during that time slot. As another example, if the receiving device does not know the transmit power of one or more devices, it may not perform any AGC operations. Alternatively, if the receiving device does not know the transmit power of one or more devices, it can perform any AGC operations only for the devices whose transmit power it knows is used for. Therefore, in such cases where AGC operations are not performed or are inaccurate, as shown in Figure 3B, the second time slot may have a smaller / normally sized data portion (compared to the data portion of time slot m in Figure 3A). The additional antenna ports / TRP for each device, as well as the directional nature of 5G communication and other beamforming wireless schemes, complicate such AGC prediction.

[0066] Figure 3D illustrates an example schematic of a multi-antenna port / TRP device operating during two time slots. In the example of Figure 3D, the device is a vehicle. As shown in Figure 3D, the vehicle has two antenna ports: a forward-facing (e.g., facing a forward / forward-oriented antenna) TRP (TRP1) and a backward-facing (e.g., facing a backward / backward-oriented antenna) TRP1 (TRP2). For a first transmission, the first TRP (TRP1) has a higher individual transmit power, and the second TRP (TRP2) has a lower transmit power. For one or more future transmissions (such as a second transmission), the first TRP (TRP1) has a lower transmit power, and the second TRP (TRP2) has a higher transmit power. Even though the total transmit power used for each transmission may be the same at the transmitting device, a particular receiving device will receive different amounts of total transmit power based on its location. For example, if the receiving device is at the front of the vehicle, the receiving device will actually receive less total power for the second transmission due to the reduced transmit power of the first TRP (TRP1). Therefore, without instructions for multiple TRP operations, the receiver gain setting will be inaccurate, or it will be completely unable to perform AGC, similar to what is shown in Figure 3B. Thus, for traditional networks, AGC prediction operations can only be performed in a limited number of cases and cannot be performed for multiple TRP operations.

[0067] Figure 4 illustrates an example of a wireless communication system 400 supporting AGC determination of Total Transmit Power (TTP) and / or Quasi-Co-location (QCL) for multiple TRPs, according to various aspects of this disclosure. Two signals transmitted from the same antenna port typically experience the same radio channel, while transmitting two signals from two different antenna ports may result in the two signals experiencing different radio conditions. However, there may be cases where signals transmitted from two different antenna ports experience radio channels with similar conditions and / or common channel characteristics. In such cases, the antenna ports are referred to as quasi-co-located or QCL. For example, if the characteristics of a channel transmitting symbols on one antenna port can be inferred from the channel transmitting symbols on that antenna port, the two antenna ports are typically referred to as quasi-co-located. Channel conditions may include one or more of Doppler shift, Doppler spread, average delay, delay spread, spatial reception parameters, etc. These conditions can be grouped, and when these conditions are the same, the type of QCL can be referred to as QCL type A, B, C, etc.

[0068] In some examples, wireless communication system 400 can implement aspects of wireless communication system 100. For example, wireless communication device 400 may include UE 115 and a second device 405 (e.g., a network entity, such as a base station or a second UE). Wireless communication system 400 may optionally include a third device 401 (e.g., a third UE). The TTP and / or QCL indication operations described herein can implement AGC for multiple TRPs (mTRPs) and in side link channel communication. Therefore, AGC and its advantages can be applied to mTRP and / or side link channel communication. Thus, vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) type communication can now be able to perform AGC operations and / or have AGC predictions with increased accuracy. Therefore, when operating using mTRP and / or side link channel communication, throughput and reliability are increased, and therefore, network and device performance can be improved.

[0069] The second device 405 and UE 115 can be configured to communicate via frequency bands, such as FR1 with frequencies from 410 to 7125 MHz, FR2 with frequencies from 24250 to 52600 MHz for millimeter waves, and / or one or more other frequency bands. It should be noted that for some data channels, the subcarrier spacing (SCS) can be equal to 15, 30, 60, or 120 kHz. The second device 405 and UE 115 can be configured to communicate via one or more component carriers (CCs) (such as the representative first CC 481, second CC 482, third CC 483, and fourth CC 484). Although four CCs are shown, this is for illustrative purposes only, and more or fewer CCs may be used. One or more CCs can be used to transmit control channel transmissions, data channel transmissions, and / or sidelink channel transmissions.

[0070] Such transmissions may include the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Physical Downlink Control Channel (PSCCH), Physical Downlink Shared Channel (PSSCH), or Physical Downlink Feedback Channel (PSFCH). Such transmissions can be scheduled using aperiodic granting and / or periodic granting.

[0071] Each periodic license can have a corresponding configuration, such as configuration parameters / settings. The periodic license configuration can include configured license (CG) configurations and settings. Alternatively, one or more periodic licenses (e.g., their CGs) can have or be assigned a CC ID (such as the expected CC ID).

[0072] Each CC can have corresponding configurations, such as configuration parameters / settings. Configurations may include bandwidth, bandwidth portion, HARQ procedure, TCI status, RS, control channel resources, data channel resources, or combinations thereof. Alternatively, one or more CCs may have or be assigned a cell ID, a bandwidth portion (BWP) ID, or both. The cell ID may include a unique cell ID for the CC, a virtual cell ID, or a specific cell ID for a particular CC among multiple CCs. Alternatively, one or more CCs may have or be assigned a HARQ ID. Each CC may also have corresponding management functions, such as beam management, BWP handover functions, or both. In some implementations, two or more CCs are quasi-co-located, such that these CCs have the same beam and / or the same symbol.

[0073] In some implementations, control information can be transmitted via the second device 405 and UE 115. For example, control information can be transmitted using MAC-CE transmission, RRC transmission, DCI transmission, another transmission, or a combination thereof.

[0074] UE 115 may include various components (e.g., architecture, hardware components) for performing one or more of the functions described herein. These components may include, for example, a processor 402, a memory 404, a transmitter 410, a receiver 412, an encoder 413, a decoder 414, an antenna manager 415, a sidelink channel manager 416, and antennas 252a-r. Processor 402 may be configured to execute instructions stored in memory 404 to perform the operations described herein. In some implementations, processor 402 includes or corresponds to controller / processor 280, and memory 404 includes or corresponds to memory 282. Memory 404 may also be configured to store second transmission indication data 406, individual transmit power data 408, TTP QCL data 442, setting data 444, or combinations thereof, as further described herein.

[0075] The second transmission indication data 406 includes or corresponds to data associated with or corresponding to information identifying one or more second transmissions (e.g., 454 and / or 456) indicated by the first transmission 452. In some implementations, at least one second transmission is associated with the first transmission. For example, the second transmission indication data 406 may indicate one or more retransmissions of the first transmission. As another example, at least one of the one or more second transmissions may differ from the first transmission, such as having different data packets.

[0076] Individual transmit power data 408 includes or corresponds to data indicating or corresponding to the transmit power of a specific antenna (such as a specific antenna port or TRP). For example, individual transmit power data 408 includes or corresponds to the transmit power used to transmit the first transmission. Additionally, individual transmit power data 408 includes one or more transmit powers planned for one or more second transmissions. For example, for the first antenna port (e.g., TRP 1), UE 115 plans to use x dB of individual transmit power (ITP) for the second transmission and y dB of ITP for the third transmission; and for the second antenna port (e.g., TRP 2), UE 115 plans to use y dB of ITP for the second transmission and x dB of ITP for the third transmission.

[0077] TTP QCL data 442 includes or corresponds to data indicating or corresponding to a QCL indication identifying the total transmit power for one or more future transmissions. TTP QCL data 442 may also include data indicating or corresponding to a QCL indication identifying the total transmit power for a current or previous transmission (such as a first transmission 452 indicating a planned future transmission). TTP QCL data 442 may indicate a specific QCL indication mode or type, such as relative indication, absolute indication, single-bit indication, bitmap indication, index indication, etc., or combinations thereof. Exemplary QCL indication types are further described with reference to Figure 5. Alternatively, transmit power configuration data may be sent instead of TTP QCL data 442. Transmit power configuration information may be an indication of the TTP. Furthermore, transmit power configuration is a generalization and extension of TTP QCL indication. Transmit power configuration data may be used to indicate one or more related QCLs regarding total transmit power, transmit power distribution on the transmit antenna, antenna / TRP selection, transmit precoder, etc. Alternatively, transmit power configuration data may indicate one or more of the following, independent of QCL information: total transmit power, transmit power distribution on the transmit antenna, antenna / TRP selection, transmit precoder, etc. Transmit power configuration may include any transmission-related changes implemented by the transmitting UE that may affect the receive power at the receiving UE.

[0078] The setting data 444 includes or corresponds to data associated with the TTP QCL indication. The setting data 444 may include one or more types of TTP QCL indication modes and / or thresholds or conditions for selecting and / or implementing the TTP QCL indication mode. Furthermore, the setting data 444 may include AGC-related data. For example, the setting data 444 may include data for predicting or calculating an AGC value based on the TTP QCL indication, and the predicted or calculated AGC value.

[0079] Transmitter 410 is configured to send data to one or more other devices, and receiver 412 is configured to receive data from one or more other devices. For example, transmitter 410 may send data via a network (such as a wired network, a wireless network, or a combination thereof), and receiver 412 may receive data via a network (such as a wired network, a wireless network, or a combination thereof). For example, UE 115 may be configured to send and / or receive data via: direct device-to-device connection, local area network (LAN), wide area network (WAN), modem-to-modem connection, Internet, intranet, extranet, cable transmission system, cellular communication network, any combination thereof, or any other communication network now known or later developed that allows two or more electronic devices to communicate therein. In some implementations, transmitter 410 and receiver 412 may be replaced by transceivers. Additionally or alternatively, transmitter 410, receiver 412, or both may include or correspond to one or more components of UE 115 described with reference to FIG. 2.

[0080] Encoder 413 and decoder 414 can be configured to encode and decode data for transmission. Antenna manager 415 can be configured to determine and perform antenna mode management and transmit power selection operations. For example, antenna manager 415 is configured to determine the transmit power for each antenna port for multi-TRP mode and / or side-link channel mode operation. For instance, antenna manager 415 can determine to use a first transmit power for a first antenna and a second transmit power for a second antenna based on a specific operating mode and receiver characteristics (e.g., type and / or location). Specifically, when data is relevant to all, antenna manager 415 can determine to alternate or scan transmit power, or antenna manager 415 can determine to focus transmit power on a specific location for a particular receiving device based on location. As an example, vehicle-to-vehicle communication for brake indication can be transmitted at higher power from a rear-facing antenna, while communication to a traffic signal can be transmitted at higher power from a front-facing antenna depending on its usual location.

[0081] The SL channel manager 416 can be configured to determine the side link channel operating mode. For example, the SL channel manager 416 is configured to determine and / or select a specific SL channel operating mode. For instance, the SL channel manager 416 is configured to determine a V2V or V2X operating mode. The SL channel manager 416 can also be configured to apply the determined interleaving mode (e.g., interleaving symbols).

[0082] The second device 405 includes a processor 430, a memory 432, a transmitter 434, a receiver 436, an encoder 437, a decoder 438, an SL channel manager 439, an AGC calculator 440, and an antenna 234a-t. The processor 430 can be configured to execute instructions stored in the memory 432 to perform the operations described herein. In some implementations, the processor 430 includes or corresponds to a controller / processor 240, and the memory 432 includes or corresponds to a memory 242. The memory 432 can be configured to store second transmission indication data 406, individual transmit power data 408, total transmit power (TTP) QCL data 442, setting data 444, or combinations thereof, similar to UE 115 and as further described herein.

[0083] Transmitter 434 is configured to send data to one or more other devices, and receiver 436 is configured to receive data from one or more other devices. For example, transmitter 434 may send data via a network (such as a wired network, a wireless network, or a combination thereof), and receiver 436 may receive data via a network (such as a wired network, a wireless network, or a combination thereof). For example, second device 405 may be configured to send and / or receive data via: direct device-to-device connection, local area network (LAN), wide area network (WAN), modem-to-modem connection, Internet, intranet, extranet, cable transmission system, cellular communication network, any combination thereof, or any other communication network now known or later developed that allows two or more electronic devices to communicate therein. In some implementations, transmitter 434 and receiver 436 may be replaced by transceivers. Additionally or alternatively, transmitter 434, receiver 436, or both may include or correspond to one or more components of second device 405 described with reference to FIG2.

[0084] Encoder 437 and decoder 438 may include the same functionality as described with reference to encoder 413 and decoder 414, respectively. SL channel manager 439 may include similar functionality as described with reference to SL channel manager 416. AGC calculator 440 may be configured to determine AGC values ​​to be used for one or more second transmissions in a second transmission. For example, AGC calculator 440 is configured to predict the AGC to be used at the start of a time slot based on a TTP QCL indication received in a control message. For example, AGC calculator 440 uses the TTP of UE 115 and any other UE to determine a specific AGC value and set the AGC value for the time slot. AGC calculator 440 may also be configured to adjust the AGC during the time slot.

[0085] During operation of the wireless communication system 400, the second device 405 may determine that the UE 115 has TTP QCL indication capability. For example, the UE 115 may send a message 448 including a TTP QCL indication capability indicator 490. The indicator 490 may indicate TTP QCL indication capability or a specific type or mode of TTP QCL indication. In some implementations, the second device 405 sends control information to indicate to the UE 115 that a TTP QCL indication and / or a specific type of TTP QCL indication will be used. For example, in some implementations, message 448 (or another message, such as configuration transmission 450) is sent by the second device 405. Configuration transmission 450 may include or indicate settings for using a TTP QCL indication or adjusting or implementing a specific type of TTP QCL indication.

[0086] During operation, devices in wireless communication system 400 perform TTPQCL indication and AGC for multiple TRP and / or sidelink channel communication operations. For example, UE 115 may send a first transmission 452 to another wireless communication device (such as second device 105 or third device 401). The first transmission 452 may be a sidelink channel transmission. The sidelink channel transmission may include a data portion and a control portion. The data portion may include or correspond to a PSSCH transmission. The control portion may include or correspond to a PSCCH transmission. The control portion may further or alternatively correspond to a sidelink channel information (SCI) transmission (such as SCI1 or SCI2 transmission).

[0087] The control section indicates one or more future or planned second transmissions. These second transmissions may include retransmissions of the first transmission or different transmissions. The second transmissions may be indicated by a time slot or a set of time-frequency resources.

[0088] The control section also indicates the TTP QCL indication for the second transmission. For example, the QCL indicator in the control section indicates or identifies the individual transmit power of each TRP of UE 115 that will be used for the upcoming second transmission, and thus indicates the TTP used for the upcoming first transmission. The total transmit power QCL indicator may include a single-bit indication, a bitmap, an index, etc., as further described herein.

[0089] After receiving the first transmission 452, the second device 405 can determine an AGC value for one or more second transmissions. For example, the second device 405 can determine the AGC value data based on the Total Transmit Power (QCL) indication. For instance, the second device 405 can determine the AGC value based on: the transmit power of the first transmission, the transmit power indicated for the second transmission, the transmit power of other devices, and the Reference Signal Received Power (RSRP) of UE 115 and / or other devices.

[0090] UE 115 uses the TTP indicated by the TTP QCL indication in the first transmission 452 to transmit the second transmission 454 to the second device 405. The second device 405 sets the receive gain value based on the AGC value (e.g., the first AGC) at the beginning of the second transmission 454. Optionally, the second device 405 may adjust the receive gain value based on transient factors or a proposed change in transmit power to UE 115 or other transmitting devices.

[0091] Upon receiving the second transmission 454, the second device 405 can determine the AGC value for the optional third transmission 456. For example, the second device 405 can determine the second AGC value data based on the total transmit power QCL indication. For instance, the second device 405 can determine the second AGC value based on: the transmit power of the first transmission 452, the transmit power of the second transmission 454, the transmit power indicated for the third transmission 456, the transmit power of other devices (e.g., the third device 401), and the RSRP of UE 115 and / or other devices.

[0092] UE 115 uses the TTP indicated by the TTP QCL indication in the first transmission 452 to send a third transmission 456 to the second device 405. At the beginning of the third transmission 456, the second device 405 sets a second receive gain value based on a second AGC value (e.g., a second AGC). Optionally, the second device 405 may adjust the second receive gain value based on transient factors or proposed changes to the transmit power of UE 115 or other transmitting devices (e.g., the third device 401). Therefore, UE 115 and the network entity can employ AGC operation when using multiple TRPs and / or performing sidelink channel operations.

[0093] Therefore, Figure 4 illustrates an enhanced QCL indication for AGC determination for multiple TRP operations. Using the TTP QCL indication enables AGC determination for multiple TRP operations and / or improves the accuracy of AGC prediction. Performing QCL indication for AGC determination for multiple TRP operations reduces overhead and power consumption (via reduced or eliminated LNA operations during time slots), and thus achieves enhanced UE and network performance.

[0094] In some implementations, the Total Transmit Power (QCL) indication includes a single indication (e.g., a single bit) that identifies whether the individual transmit power of each TRP of the wireless communication device for a second set of one or more time-frequency resources will be the same as the individual transmit power of each TRP for a first set of time-frequency resources. By indicating the individual transmit power of each TRP, the receiving device can determine the TTP.

[0095] In some other implementations, the Total Transmit Power (QCL) indicator is a bitmap. In some such implementations, the bitmap indicates whether the same individual transmit power allocation for each TRP is being used for a second set of one or more time-frequency resources (e.g., whether the same TRP power allocation is being used). For example, the bitmap includes a single value for each time-frequency resource set in the second set for one or more time-frequency resources (e.g., transmissions), with a value of 1 indicating the same TRP power allocation and a value of 0 indicating otherwise.

[0096] In other such implementations, the bitmap includes multiple values ​​for each time-frequency resource set in a second set of one or more time-frequency resources (e.g., multiple values ​​for each transmission to indicate per-port QCL indication). For example, each value in the bitmap indicates a power relationship to the power allocated to the first time-frequency resource set. For instance, a first value indicates twice the TRP power allocation for the first time-frequency resource set, a second value indicates the same TRP power allocation for the first time-frequency resource set, a third value indicates half the TRP power allocation for the first time-frequency resource set, and a fourth value indicates no power.

[0097] In some additional implementations, the Total Transmit Power (QCL) indicator is an index that indicates whether the same individual transmit power allocation for each TRP is being used for a second set of one or more time-frequency resources. For example, this index is a TCI status index, with a value of 1 indicating the same TRP power allocation and a value of 0 indicating otherwise.

[0098] Alternatively, the Total Transmit Power (QCL) indicator provides an explicit indication for a portion of the second transmission and an implicit indication for a second portion of the second transmission. For example, the QCL indicator is a bitmap indicating a portion of time-frequency resources reserved in the second set for future resources, the bitmap indicating the repetition pattern of the information, and the repetition pattern of the information providing an indication of the remaining resources reserved in the second set for future resources.

[0099] Figure 5 illustrates an example ladder diagram for TTP QCL indication operation. Referring to Figure 5, Figure 5 is an example ladder diagram 500 for TTP QCL indication for AGC for multiple TRPs. Ladder diagram 500 shows two devices in the network, namely a first device (e.g., UE 115) and a second multi-TRP device (e.g., second device 105). The multi-TRP device has a first TRP 105a and a second TRP 105b.

[0100] At 510, the second device 105 determines the total transmit power (TTP) for one or more future transmissions. For example, the second device 105 determines one or more second transmission resources and individual transmit powers for each TRP (i.e., first TRP 105a and second TRP 105b). The second device 105 may generate an indicator for the second transmission resources (i.e., a TTP QCL indicator) and include the indicator in the first transmission.

[0101] At 515, the first TRP 105a generates and transmits a first transmission. For example, the first TRP 105a transmits a PSCCH transmission, a PSSCH transmission, or both. The first transmission indicates a future second transmission resource and a TTP QCL indication for such a resource. For example, the control portion of the first transmission indicates both the future resource and the TTP QCL indication. A particular TTP QCL indication type can be determined based on the network and / or the operating mode of the second device 105. An exemplary TTP QCL indication is further shown and described with reference to FIG6.

[0102] At 520, the second TRP 105b generates and transmits the first transmission. For example, the second TRP 105b transmits a PSCCH transmission, a PSSCH transmission, or both. The first transmission from the second TRP 105b may also indicate future second transmission resources and TTP QCL indications for such resources. As shown in the example in Figure 5, UE 115 may or may not receive such a transmission from the second TRP 105b. For example, the second TRP 105b may be transmitting using a specific beam (e.g., direction) and power, making it impossible for UE 115 to receive or decode the transmission. Furthermore, although the first transmissions at 515 and 520 are shown at different times, the first transmissions may partially overlap or occur simultaneously in time. The first transmissions at 515 and 520 may be the same transmission, i.e., having the same data packets or data portions.

[0103] At 525, UE 115 may optionally generate and send an acknowledgment transmission (ACK). For example, UE 115 sends a PUCCH transmission / UCI transmission indicating successful reception of at least one of the first transmissions and optionally indicating a confirmation indicator for TTP QCL indication and / or reserved second resources.

[0104] At 530, UE 115 determines the TTP QCL indication. For example, UE 115 extracts the TTP QCL indication from the control section of the first transmission.

[0105] At 535, UE 115 determines the TTP for a future second transmission. For example, UE 115 may determine the individual transmit power for the first TRP 105a and the individual transmit power for the second TRP 105b based on the total transmit power QCL indication. In some implementations, UE 115 may determine the TTP QCL indication to indicate different individual transmit powers for different future transmissions in the second transmission for the TRP. For further details on the indication and decoding of the indication, please refer to Figure 6.

[0106] At 530, UE 115 determines the AGC value based on the TTP QCL indication. For example, UE 115 determines the TTP for the second device based on the individual transmit power of the TRP indicated by the TTP QCL indicator, and then determines the initial gain setting for a specific second transmission based on the TTP for the second device. For example, UE 115 may calculate the AGC based on the receiver gain value for the first transmission, the total receive power for the first transmission, the RSRP level for the second device 105, the spatial configuration (e.g., beam configuration) for the first transmission, the second transmission, or both, or a combination thereof. Furthermore, UE 115 may consider transmit power from other devices (not shown). Such transmit power may also include TTP for multiple TRP devices. For example, UE 115 may also adjust the gain for other devices, similar to Figure 3B. Therefore, for a third device that has multiple TRPs and is transmitting in the same time slot / transmission resources as the second device, UE 115 may also determine AGC based on the following: receiver gain value for transmissions performed by the third device, total received power for transmissions performed by the third device, RSRP level for the third device, spatial configuration (e.g., beam configuration) for transmissions performed by the third device, or a combination thereof.

[0107] After determining the AGC value, UE 115 sets the receiver gain for a specific upcoming second transmission based on the AGC value. UE 115 can monitor incoming transmissions based on the receiver gain value. Because the receiver gain value takes into account the TTP of each multi-TRP transmitting device (e.g., by considering the individual transmit power of each TRP), the receiver gain value can be more accurate. Therefore, UE 115 can utilize less LNA gain during the second transmission or can perform no LNA-based gain adjustment during the second transmission.

[0108] At position 545, the first TRP 105a generates and transmits a second transmission. For example, the first TRP 105a transmits a second PSCCH transmission, a second PSSCH transmission, or both. The second transmission is generated and transmitted based on the transmit power indication used for the first transmission of the first TRP 105a.

[0109] At 550, the second TRP 105b generates and transmits a second transmission. For example, the second TRP 105b transmits a second PSCCH transmission, a second PSSCH transmission, or both. The second transmission is generated and transmitted based on the transmit power indication used for the first transmission of the second TRP 105b.

[0110] UE 115 receives one or both second transmissions from the TRP. UE 115 processes the second transmissions based on the receiver gain value set according to the multiple TRP AGC indicated via QCL. If UE 115 determines that the second transmission is intended for / indicates UE 115, UE 115 can decode and further process the second transmission. Alternatively, if UE 115 determines that the second transmission is not intended for / indicates UE 115, it can decide to ignore the second transmission and not further process or decode it. Furthermore, the third device can monitor transmission resources for the second transmission for transmissions intended for the third device. The third device can also determine that the second transmission is not intended for / indicates the third device and not further process or decode it.

[0111] Therefore, in the example of Figure 5, these devices employ a TTP QCL indication for AGC in multi-TRP operations. That is, when determining / performing an AGC operation, these devices can consider the individual transmit power of each TRP.

[0112] Figures 6A-6H illustrate examples of TTP QCL indication schemes. Figures 6A-6D illustrate various types of QCL indicators, and Figures 6E-6H illustrate examples of different resulting TRP transmit signal powers. Referring to Figure 6A, Figure 6A illustrates an example of a single-bit type TTP QCL indicator. A single-bit indicator can indicate whether the transmitting device intends to reuse the individual transmit power and total transmit power used for the antenna port / TRP during the first transmission for one or more future transmissions. As an illustrative example, a value of 1 can indicate the same TTP and ITP, while a value of 0 can indicate other cases, such as no indication or default indication.

[0113] Referring to Figure 6B, Figure 6B shows an example of a bitmap-type TTP QCL indicator. A bitmap indicator can provide an indication for each transmission in future transmissions. In some implementations, the bitmap indicator is device-specific. For example, similar to the single-bit indicator in Figure 6A, each bit in the bitmap indicates whether the transmitting device intends to reuse the individual transmit power and total transmit power used for the antenna port / TRP during the first transmission for a specific future transmission in one or more future transmissions. As an illustrative example, a value of 1 can indicate the same TTP and ITP, while a value of 0 can indicate other cases, such as no indication or a default indication.

[0114] In some other implementations, the bitmap is per antenna port / TRP. In such an implementation, the bitmap can include multiple bits per transmission. For example, for two TRP devices, the bitmap has two indicators per transmission, one indicator for each TRP.

[0115] Although the indications described in Figures 6A and 6B are one-bit indications (e.g., 0 or 1), in other implementations, each indication itself can be multiple bits. For example, a two-bit indicator or a four-option indicator can be used. For instance, a first value (2 or 11) indicates twice the TRP power allocation for the first transmission, a second value (1 or 10) indicates the same TRP power allocation for the first transmission, a third value (0.5 or 01) indicates half the TRP power allocation for the first transmission, and a fourth value (0 or 00) indicates no power.

[0116] Referring to Figure 6C, which shows an example of an index-type TTP QCL indicator, the index used in the example of Figure 6C is the TCI status index. In other examples, other indices / fields from the control section of the first transmission may be used. The index indicator can provide indication for each transmission in future transmissions.

[0117] In some implementations, the index indicators are device-specific. For example, each indicator in the bitmap is used to indicate the TCI state for a particular transmission for the device as a whole. For instance, TCI state 2 might indicate that the receiving device can reuse both the individual transmit power and the total transmit power used for the antenna port / TRP during the first transmission for a specific future transmission in one or more future transmissions, and TCI state 1 might indicate that the receiving device can choose not to reuse transmit power. In other implementations (such as for different indices (e.g., non-TCI state indices)), the index indicators might be device-specific (antenna port / TRP).

[0118] Referring to Figure 6D, Figure 6D illustrates an example of a partial bitmap type TTP QCL indicator. A partial bitmap indicator can provide explicit indications for some transmissions in future transmissions and implicit indications for others. For example, future reserved resources could indicate the next 10 transmissions. However, the bitmap may only include indications for a subset of these transmissions (such as two or five of these transmissions). The bitmap indications can be interpreted by the receiving device as repeating for the remaining transmissions in the reserved allocation. Similar to the bitmap indications of Figures 6A and 6B, the individual indications of a partial bitmap can be single-bit indicators, multi-bit indicators, per-device indicators, daily line port / TRP indicators, or any combination thereof. Alternatively, in other implementations, the TTP QCL indicator can be a partial or repeating index, as described with reference to Figure 6C.

[0119] Referring to Figures 6E-6H, an example transmit power configuration is shown. Figures 6E-6H show a vehicle with two transmit power units (TRPs), with the first TRP (TRP1) located at the front of the vehicle and the second TRP (TRP2) located at the rear. Figure 6E shows the first TRP (TRP1) at the first transmit power and the second TRP (TRP2) at the second transmit power. Figure 6F shows the first TRP (TRP1) at the second transmit power and the second TRP (TRP2) at the first transmit power. Figure 6G shows both TRPs (TRP1 and TRP2) at the second transmit power. Figure 6H shows both TRPs (TRP1 and TRP2) at the first transmit power.

[0120] Although Figure 4-6H is an example of a TTP QCL indication, in other implementations, a transmit power configuration indication can be sent instead of a TTP QCL indication. Furthermore, the example configuration and indication of the TTP QCL indicator can be used to indicate a transmit power configuration indicator or indication.

[0121] Figure 7 is a flowchart illustrating example blocks performed by a UE configured according to one aspect of this disclosure. These example blocks will also be described with respect to UE 115 as shown in Figure 9. Figure 9 is a block diagram illustrating UE 115 configured according to one aspect of this disclosure. UE 115 includes the structure, hardware, and components shown for UE 115 in Figure 2. For example, UE 115 includes a controller / processor 280 that operates to execute logical or computer instructions stored in memory 282, and components that control UE 115 and provide the features and functions of UE 115. Under the control of the controller / processor 280, UE 115 transmits and receives signals via wireless radio units 900a-r and antennas 252a-r. The wireless radio units 900a-r include various components and hardware as shown for UE 115 in Figure 2, including modulators / demodulators 254a-r, MIMO detectors 256, receive processors 258, transmit processors 264, and TX MIMO processors 266. As shown in the example in Figure 9, memory 282 stores side-link channel logic 902, multi-TRP logic 903, AGC logic 904, TTP QCL logic 905, LNA logic 906, and setting data 907.

[0122] At block 700, a wireless communication device (such as a UE) uses a first set of transmission resources to transmit a transmission. This transmission includes an indication of a second set of one or more future transmission resources intended by the wireless communication device for one or more second transmissions, and includes a total transmit power (QCL) indication for at least one of the one or more second transmissions. For example, UE 115 transmits a transmission including a control portion indicating future reserved transmission resources (e.g., a set of time-frequency resources) and a power indication for the future reserved transmission resources, as described with references 4, 5, and 6A-H. For example, the control portion may include a TTP QCL indicator (such as described with reference to Figures 6A-6D) indicating the TTP for the future reserved transmission resources. The TTP may be indicated by indicating the ITP for each antenna port / TRP of the UE.

[0123] At block 701, UE 115 transmits a specific transmission from one or more second transmissions using a specific set of transmission resources in a second set of one or more transmission resources, based on the Total Transmit Power (TTP) QCL indication. For example, UE 115 generates and transmits a second transmission based on the TTP QCL indication of a first transmission, as described with reference to Figures 4 and 5. For instance, UE 115 may generate and transmit a PSCCH transmission, a PSSCH transmission, or both, and the PSSCH (if included) may be the same as or different from the PSSCH of the first transmission. Furthermore, based on the TTP QCL indication, the first and second transmissions may have the same or different TTP and / or ITP settings.

[0124] In another approach, a transmit power configuration indication can be sent instead of a total transmit power QCL indication. The transmit power configuration indication can be an indication of the TTP. Furthermore, transmit power configuration is a generalization and extension of the TTP QCL indication. The transmit power configuration QCL indication can be used to indicate a QCL with respect to one or more of the following: total transmit power, transmit power distribution on the transmit antenna, antenna / TRP selection, transmit precoder, etc. Alternatively, transmit power configuration data can indicate one or more of the following, independent of QCL information: total transmit power, transmit power distribution on the transmit antenna, antenna / TRP selection, transmit precoder, etc. Transmit power configuration can include any transmission-related changes that may affect the received power at the receiving UE, depending on the implementation of the transmitting UE.

[0125] In other implementations, UE 115 may perform additional boxes (or UE 115 may be configured to perform additional operations). For example, UE 115 may perform one or more of the operations described above. As another example, a wireless communication device may perform one or more of the following aspects.

[0126] In the first aspect, the wireless communication device is a multi-TRP UE and has multiple TRPs.

[0127] In the second aspect, either alone or in combination with one or more of the above aspects, the total transmit power (QCL) indication includes transmit power information for each of the multiple transmit power resources (TRPs).

[0128] In the third aspect, either alone or in combination with one or more of the above aspects, the wireless communication device is operating in V2X mode, and the total transmit power QCL indication enables the receiving device to perform automatic gain control (AGC) prediction.

[0129] In the fourth aspect, either alone or in combination with one or more of the above aspects, the total transmit power (QCL) indication is included in the control message of the first transmission.

[0130] In the fifth aspect, control messages are PSCCH transmissions, either alone or in combination with one or more of the above aspects.

[0131] In the sixth aspect, control messages are SCI1 transmissions, either alone or in combination with one or more of the above aspects.

[0132] In the seventh aspect, control messages are SCI2 transmissions, either alone or in combination with one or more of the above aspects.

[0133] In the eighth aspect, the first transmission also includes a data portion, either alone or in combination with one or more of the above aspects.

[0134] In the ninth aspect, either alone or in combination with one or more of the above aspects, the data portion is PSSCH transmission.

[0135] In the tenth aspect, individually or in combination with one or more of the above aspects, at least one of the one or more second transmissions includes the same data packets as the first transmission.

[0136] In the eleventh aspect, individually or in combination with one or more of the above aspects, at least one of the one or more second transmissions includes data packets different from the first transmission.

[0137] In the twelfth aspect, either alone or in combination with one or more of the above aspects, the total transmit power QCL indicator provides a QCL indication for indicating the total transmit power for each of the second sets of transmission resources in one or more transmission resources.

[0138] In the thirteenth aspect, either alone or in combination with one or more of the above aspects, the total transmit power (QCL) indication includes a single indication that identifies whether the individual transmit power of each TRP of the wireless communication device for a second set of one or more transmission resources will be the same as the individual transmit power of each TRP for a first set of transmission resources.

[0139] In the fourteenth aspect, either alone or in combination with one or more of the above aspects, the total transmit power QCL indication is a bitmap, and the bitmap indicates whether the same individual transmit power allocation for each TRP is being used for a second set of one or more transmission resources (e.g., whether the same TRP power allocation is being used).

[0140] In the fifteenth aspect, individually or in combination with one or more of the above aspects, the bitmap includes a single value for each of the second sets of transmission resources (e.g., transmissions) for one or more transmission resources, and the value 1 indicates the same TRP power allocation, and the value 0 indicates other cases.

[0141] In the sixteenth aspect, individually or in combination with one or more of the above aspects, the bitmap includes multiple values ​​for each of the second sets of transmission resources (e.g., multiple values ​​for each transmission to indicate per-port QCL indication), and the values ​​of the bitmap indicate a power relationship with the power for the first set of transmission resources.

[0142] In the seventeenth aspect, individually or in combination with one or more of the above aspects, the first value indicates twice the TRP power allocation for the first transmission resource set, the second value indicates the same TRP power allocation for the first transmission resource set, the third value indicates half the TRP power allocation for the first transmission resource set, and the fourth value indicates no power.

[0143] In the eighteenth aspect, either alone or in combination with one or more of the above aspects, the total transmit power QCL indication is an index, and this index indicates whether the same individual transmit power allocation for each TRP is being used for a second set of one or more transmission resources.

[0144] In the nineteenth aspect, alone or in combination with one or more of the above aspects, the index is a TCI status index, and a value of 1 indicates the same TRP power allocation, while a value of 0 indicates other cases.

[0145] In the twentieth aspect, either alone or in combination with one or more of the above aspects, the total transmit power QCL indication is a bitmap indicating a portion of the transmission resources reserved in the second set for future use, the bitmap indicating the repetition pattern of the information, and the repetition pattern of the information providing an indication of the remaining resources reserved in the second set for future use.

[0146] In the twenty-first aspect, either alone or in combination with one or more of the above aspects, the transmission resource corresponds to the time-frequency resource, and the total transmit power (QCL) indicator is used to indicate the transmit power information for each TRP of the UE.

[0147] In the twenty-second aspect, either alone or in combination with one or more of the above aspects, the wireless communication device transmits a capability message prior to transmission, the capability message indicating that the wireless communication device is configured for QCL-based total transmit power indication.

[0148] In the twenty-third aspect, either alone or in combination with one or more of the above aspects, the wireless communication device receives a capability message prior to transmission, the capability message indicating that the second wireless communication device is configured for QCL-based total transmit power indication.

[0149] In the twenty-fourth aspect, either alone or in combination with one or more of the above aspects, the wireless communication device receives a configuration message from the second wireless communication device indicating a total transmit power indication mode based on QCL before transmission.

[0150] In another aspect, a wireless communication method includes: transmitting a transmission by a wireless communication device using a first set of transmission resources, wherein the transmission includes an indication of a second set of one or more future transmission resources intended by the wireless communication device for one or more second transmissions, and wherein the transmission includes a transmit power configuration indication for at least one of the one or more second transmissions; and transmitting a specific transmission of the one or more second transmissions by the wireless communication device using a specific set of transmission resources from the second set of one or more transmission resources based on the transmit power configuration indication.

[0151] In an additional aspect, the method also includes any of the second to twenty-fourth aspects.

[0152] In addition, the transmit power configuration indication is a relative, differential, or ratio type indication.

[0153] In addition, the transmit power configuration includes total transmit power indication, power distribution indication, transmit antenna configuration, precoder configuration, or a combination thereof.

[0154] In addition, the transmit power configuration includes total transmit power indication, power distribution indication, transmit antenna configuration, precoder configuration, or a combination thereof.

[0155] In addition, transmit power configuration is used for QCL indicators or information regarding one or more of the following: total transmit power, transmit power distribution on the transmit antenna, antenna selection, TRP selection, or transmit precoder.

[0156] In an additional aspect, the transmit power configuration indicates any transmission changes performed by the transmitting UE that may significantly affect the receive power at the receiving UE.

[0157] Therefore, the UE and the base station can execute QCL indications for AGC determination for multiple TRP operations. By executing QCL indications for AGC determination for multiple TRP operations, throughput and reliability can be improved.

[0158] Figure 8 is a flowchart illustrating example blocks performed by a wireless communication device configured according to another aspect of this disclosure. The wireless communication device is a receiving device and may be a UE or a base station. These example blocks will also be described with respect to a base station 105 (e.g., a gNB) as shown in Figure 10. Figure 10 is a block diagram illustrating a base station 105 configured according to one aspect of this disclosure. Base station 105 includes the structure, hardware, and components shown for base station 105 of Figure 2. For example, base station 105 includes a controller / processor 240 that operates to execute logical or computer instructions stored in memory 242, and components that control base station 105 and provide the features and functions of base station 105. Under the control of controller / processor 240, base station 105 transmits and receives signals via wireless radio units 1001a-t and antennas 234a-t. The wireless radio unit 1001a-t includes various components and hardware as shown in FIG. 2 for base station 105, including modulator / demodulator 232a-t, MIMO detector 236, receiver processor 238, transmitter processor 220, and TX MIMO processor 230. As shown in the example of FIG. 10, memory 242 stores side-link channel logic 1002, multi-TRP logic 1003, AGC logic 1004, TTP QCL logic 1005, LNA logic 1006, and setup data 1007. One or more of 1002-1007 may include or correspond to one of 902-907.

[0159] At block 800, a wireless communication device (such as a UE or a base station) receives a transmission from a second wireless communication device for a first set of transmission resources. This transmission includes an indication of a second set of one or more future transmission resources intended by the second wireless communication device for one or more second transmissions, and the transmission includes a total transmit power (QCL) indication for at least one of the second sets of transmission resources. For example, UE 115 or base station 105 receives a transmission including a control portion indicating future reserved transmission resources (e.g., a time-frequency resource set) and a power indication for the future reserved transmission resources, as described with reference to Figures 4, 5, and 6A-H. For example, the control portion may include a TTP QCL indicator (such as described with reference to Figures 6A-6D) indicating the TTP for the future reserved transmission resources. The TTP may be indicated by indicating the ITP for each antenna port / TRP of the UE.

[0160] At block 801, UE 115 or base station 105 determines the total transmit power for a specific set of transmission resources in a second set of one or more transmission resources based on the total transmit power QCL indication. For example, UE 115 or base station 105 determines a specific type of TTP QCL indicator (such as a TTP QCL indication pattern) and determines the ITP for each antenna port based on the TTP QCL indicator, as described with reference to Figures 4, 5 and 6A-6H.

[0161] At box 802, UE 115 or base station 105 determines the receiver gain value to be applied to reception during a particular transmission resource set based on the total transmit power for that specific transmission resource set. For example, UE 115 or base station 105 calculates the predicted receive gain to be used based on the TTP and ITP for an upcoming reserved transmission resource set, as described with reference to Figures 3A, 4, and 5.

[0162] At block 803, UE 115 or base station 105 uses a receive gain value to monitor a specific transmission in one or more second transmissions during a specific set of transmission resources. For example, UE 115 or base station 105 receives a second transmission based on the TTP QCL indication of the first transmission, as described with reference to Figures 4 and 5. For instance, UE 115 or base station 105 receives a PSCCH transmission, a PSSCH transmission, or both, and the PSSCH (if included) may be the same as or different from the PSSCH of the first transmission. Furthermore, based on the TTP QCL indication, the first and second transmissions may have the same or different TTP settings and / or ITP settings.
