[0004] open field

[0005] Various aspects of this disclosure generally relate to wireless communication, and more particularly to techniques and apparatus for power control for concurrent reception. Background Technology

[0006] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0007] Wireless communication networks may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a B-node, gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0008] The multiple access technologies mentioned above have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (also known as 5G) is an enhancement set to the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards that support beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation, using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL) (CP-OFDM), and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL). However, with the continued growth in demand for mobile broadband access, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunications standards that employ them.

[0033] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based at least in part on the teachings herein, those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.

[0034] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented in hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0035] It should be noted that although the aspects herein may be described using terms commonly associated with 3G and / or 4G wireless technologies, the aspects of this disclosure may be applied to communication systems based on other generations, such as 5G and later, including NR technologies.

[0036] Figure 1This is a diagram illustrating a network 100 in which various aspects of this disclosure can be practiced. Network 100 can be an LTE network or some other wireless network, such as a 5G or NR network. Wireless network 100 may include several BS110s (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B-node, gNB, 5G B-node (NB), access point, transmit / receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0037] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with service subscriptions. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with service subscriptions. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1 In the example shown, BS110a can be a macro BS for macro cell 102a, BS110b can be a pico BS for pico cell 102b, and BS110c can be a femto BS for femto cell 102c. A BS 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” are used interchangeably herein.

[0038] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or interconnect to one or more other BSs or network nodes (not shown) in the access network 100 via various types of backhaul interfaces (such as direct physical connections, virtual networks, and / or the like of any suitable transport network).

[0039] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS110a and UE 120d to facilitate communication between BS110a and UE 120d. A relay station may also be referred to as a relay BS, relay base station, relay, etc.

[0040] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0041] Network controller 130 can be coupled to a set of BSs and can provide coordination and control over these BSs. Network controller 130 can communicate with each BS via backhaul. These BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0042] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0043] Some UEs can be considered Machine-Type Communication (MTC) devices, or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices such as sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components, memory components, etc.

[0044] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0045] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary). For example, UEs 120 may use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this scenario, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0046] As indicated above, Figure 1 This is provided merely as an example. Other examples are possible and may differ from those provided. Figure 1 The example described.

[0047] Figure 2 It shows that it can be Figure 1 A block diagram of design 200 for base station 110 and UE 120, one of the base stations and one of the UEs. Base station 110 may be equipped with T antennas 234a to 234t, while UE 120 may be equipped with R antennas 252a to 252r, where generally T≥1 and R≥1.

[0048] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its own output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t, respectively. According to the aspects described in more detail below, position coding can be used to generate synchronization signals to convey additional information.

[0049] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the 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 all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The channel processor can determine the received power of the reference signal (RSRP), the received signal strength indicator (RSSI), the received quality of the reference signal (RSRQ), the channel quality indicator (CQI), and so on.

[0050] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, CQI, etc.). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded by TX MIMO processor 266 where applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 where applicable, and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. The receiver processor 238 can provide decoded data to the data sink 239 and decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0051] In some respects, one or more components of UE 120 may be included in a housing. This includes the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2Any other component may perform one or more techniques associated with power control for concurrent reception, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component may execute or direct, for example Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. Scheduler 246 may schedule the UE for data transmission on downlink and / or uplink.

[0052] In some aspects, UE 120 may include means for determining multiple powers for a target wireless node communicating with multiple other wireless nodes via multiple links of a network, means for causing the target wireless node or at least one of the multiple other wireless nodes to use the multiple powers, and for concurrently transmitting to the target wireless node using the multiple links, at least in part based on the determination of the multiple powers, etc. In some aspects, such means may include combining Figure 2 One or more components of the described UE 120.

[0053] In some aspects, base station 110 may include means for determining multiple powers for a target wireless node communicating with multiple other wireless nodes via multiple links of a network, means for causing the multiple other wireless nodes to use the multiple powers and to concurrently transmit to the target wireless node using the multiple links, at least in part based on the determination of the multiple powers, and so on. In some aspects, such means may include combinations of... Figure 2 One or more components of the described base station 110.

[0054] As indicated above, Figure 2 This is provided merely as an example. Other examples are possible and may differ from those provided. Figure 2 The example described.

[0055] Figure 3A An example frame structure 300 for Frequency Division Duplex (FDD) in a telecommunications system (e.g., NR) is shown. The transmission timeline of each of the downlink and uplink can be divided into units of radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z≥1) subframes (e.g., with indices 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., in... Figure 3A The diagram shows 2 per subframem There are several time slots, where m is a parameter design for transmission, such as 0, 1, 2, 3, 4, etc. Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., as shown in the image). Figure 3A (As shown in the diagram), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two time slots (e.g., when m=1), the subframe may include 2L symbol periods, wherein the 2L symbol periods in each subframe can be assigned indices 0 to 2L-1. In some aspects, the scheduling unit for FDD can be frame-based, subframe-based, time slot-based, symbol-based, etc.

[0056] While this article describes some techniques using terms such as frames, subframes, and time slots, these techniques are equally applicable to other types of wireless communication architectures that can be referred to in 5G NR using terms other than "frame," "subframe," and "time slot." In some respects, a wireless communication architecture can refer to a communication unit with periodic time boundaries defined by wireless communication standards and / or protocols. Additionally or alternatively, terms related to... Figure 3A The wireless communication architectures shown are configured differently.

[0057] In some telecommunications systems (e.g., NR), base stations may transmit synchronization signals. For example, a base station may transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and so on on the downlink for each cell supported by that base station. The PSS and SSS can be used by the UE for cell search and acquisition. For example, the PSS can be used by the UE to determine symbol timing, while the SSS can be used by the UE to determine the physical cell identifier associated with the base station and frame timing. The base station may also transmit a physical broadcast channel (PBCH). The PBCH may carry system information, such as system information supporting the UE's initial access.

[0058] In some aspects, base stations may transmit PSS, SSS, and / or PBCH according to a synchronization communication level (e.g., a synchronization signal (SS) level) that includes multiple synchronization communications (e.g., SS blocks), as combined below. Figure 3B As described.

[0059] Figure 3B This is a conceptual block diagram illustrating an example SS layer, which is an example of a synchronous communication layer. Figure 3B As shown, the SS hierarchy may include an SS burst set, which may include multiple SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of an SS burst that can be transmitted by the base station). As further shown, each SS burst may include one or more SS blocks (identified as SS block 0 to SS block (b...).最大_SS-1 ), where b 最大_SS-1 This is the maximum number of SS blocks that can be carried by an SS burst. In some respects, different SS blocks can be beamformed differently. SS burst sets can be transmitted periodically by the wireless node, such as every X milliseconds. Figure 3B As shown in the diagram. In some respects, SS burst sets can have fixed or dynamic lengths, as in... Figure 3B Y is represented as milliseconds.

[0060] Figure 3B The SS burst set shown is an example of a synchronization communication set, and other synchronization communication sets can be used in conjunction with the techniques described herein. Furthermore, Figure 3B The SS block shown is an example of synchronous communication, and other synchronous communication methods can be used in conjunction with the techniques described herein.

[0061] In some aspects, an SS block includes resources carrying a PSS, SSS, PBCH, and / or other synchronization signals (e.g., a third synchronization signal (TSS)) and / or a synchronization channel. In some aspects, multiple SS blocks are included in an SS burst, and each SS block across the SS burst may have the same PSS, SSS, and / or PBCH. In some aspects, a single SS block may be included in an SS burst. In some aspects, the length of an SS block may be at least four symbol periods, wherein each symbol carries one or more of a PSS (e.g., occupying one symbol), an SSS (e.g., occupying one symbol), and / or a PBCH (e.g., occupying two symbols).

[0062] In some aspects, synchronization communication (e.g., an SS block) may include base station synchronization communication for transmission, which may be referred to as Tx BS-SS, Tx gNB-SS, etc. In some aspects, synchronization communication (e.g., an SS block) may include base station synchronization communication for reception, which may be referred to as Rx BS-SS, Rx gNB-SS, etc. In some aspects, synchronization communication (e.g., an SS block) may include user equipment synchronization communication for transmission, which may be referred to as Tx UE-SS, Tx NR-SS, etc. Base station synchronization communication (e.g., for transmission by a first base station and reception by a second base station) may be configured for synchronization between base stations, while user equipment synchronization communication (e.g., for transmission by a base station and reception by a user equipment) may be configured for synchronization between a base station and a user equipment.

[0063] In some respects, base station synchronization communication may include information different from user equipment synchronization communication. For example, one or more base station synchronization communications may exclude PBCH communication. Additionally or alternatively, base station synchronization communication and user equipment synchronization communication may differ with respect to one or more of the following: time resources for transmission or reception of synchronization communication, frequency resources for transmission or reception of synchronization communication, periodicity of synchronization communication, waveform of synchronization communication, beamforming parameters for transmission or reception of synchronization communication.

[0064] In some respects, the symbols of the SS block are coherent, such as Figure 3B As shown in the diagram. In some aspects, the symbols of an SS block are non-coherent. Similarly, in some aspects, one or more SS blocks of an SS burst can be transmitted in coherent radio resources (e.g., coherent symbol periods) during one or more subframes. Additionally or alternatively, one or more SS blocks of an SS burst can be transmitted in non-coherent radio resources.

[0065] In some aspects, an SS burst can have a burst period, whereby the base station transmits each SS block of the SS burst according to that burst period. In other words, these SS blocks can be repeated during each SS burst period. In other aspects, an SS burst set can have a burst set periodicity, whereby the base station transmits each SS burst of the SS burst set according to a fixed burst set periodicity. In other words, the SS burst can be repeated during each SS burst set period.

[0066] The base station may transmit system information, such as System Information Blocks (SIBs), on the Physical Downlink Shared Channel (PDSCH) in certain subframes. The base station may transmit control information / data on the Physical Downlink Control Channel (PDCCH) for C symbol periods of a subframe, where B can be configured for each subframe. The base station may transmit traffic data and / or other data on the PDSCH in the remaining symbol periods of each subframe.

[0067] As indicated above, Figure 3A and 3B This is provided as an example. Other examples are possible and may differ from those provided. Figure 3A and 3B The example described.

[0068] Figure 4An example subframe format 410 with a normal cyclic prefix is ​​shown. Available time-frequency resources can be divided into resource blocks. Each resource block can cover a set of subcarriers (e.g., 12 subcarriers) in a time slot and can include several resource elements. Each resource element can cover one subcarrier in one symbol period (e.g., temporally) and can be used to transmit a modulation symbol that can be a real or complex value. In some aspects, subframe format 410 can be used to transmit SS blocks carrying PSS, SSS, PBCH, etc., as described herein.

[0069] For FDD in certain telecommunications systems (e.g., NR), interleaving structures can be used for both the downlink and uplink. For example, a Q-strand interleaving with indices 0 to Q-1 can be defined, where Q can be equal to 4, 6, 8, 10, or some other value. Each interleaving may include subframes spaced Q frames apart. Specifically, interleaving q may include subframes q, q+Q, q+2Q, etc., where q∈{0,…,Q-1}.

[0070] The UE may be located within the coverage of multiple service base stations (BSs). One of these BSs can be selected to serve the UE. The serving BS can be selected, at least in part, based on various criteria such as received signal strength, received signal quality, path loss, etc. Received signal quality can be quantified by signal-to-noise ratio (SINR), reference signal received quality (RSRQ), or some other metric. The UE may operate in a strong interference scenario, in which the UE may observe severe interference from one or more interfering BSs.

[0071] While aspects of the examples described herein may be associated with NR or 5G technologies, aspects of this disclosure are adaptable for use with other wireless communication systems. New Radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., different from an air interface based on Orthogonal Frequency Division Multiple Access (OFDMA)) or a fixed transport layer (e.g., different from Internet Protocol (IP)). In each aspect, NR may utilize OFDM with CP (referred to herein as Cyclic Prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, and may utilize CP-OFDM on the downlink and include support for half-duplex operation using Time Division Duplex (TDD). In each aspect, NR may, for example, utilize OFDM with CP (referred to herein as CP-OFDM) and / or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) on the uplink, and may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeting wide bandwidth (e.g., 80 MHz and above), millimeter wave (mmW) services targeting high carrier frequencies (e.g., 60 GHz), massive MTC (mMTC) services targeting non-backward compatible MTC technologies, and / or mission-critical services targeting ultra-reliable low latency communication (URLLC) services.

[0072] In some aspects, a single component carrier bandwidth of 100 MHz can be supported. An NR resource block can span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kHz over a duration of 0.1 milliseconds (ms). Each radio frame can include 40 subframes with a length of 10 ms. Therefore, each subframe can have a length of 0.25 ms. Each subframe can indicate the link direction (e.g., DL or UL) for data transmission, and the link direction for each subframe can be dynamically switched. Each subframe can include DL / UL data and DL / UL control data.

[0073] It supports beamforming and dynamically configurable beam direction. It also supports MIMO transmission with precoding. MIMO configuration in DL can support up to 8 transmit antennas (with up to 8 streams in multi-layer DL transmission) and up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE is supported. Up to 8 serving cells can be used to support the aggregation of multiple cells. Alternatively, NR can support different air interfaces in addition to OFDM-based interfaces. NR networks can include entities such as central cells or distributed cells.

[0074] As indicated above, Figure 4 This is provided as an example. Other examples are possible and may differ from those provided. Figure 4The example described.

[0075] Figure 5 An example logical architecture of a distributed RAN 500 according to various aspects of this disclosure is described. A 5G access node 506 may include an access node controller (ANC) 502. The ANC may be the central unit (CU) of the distributed RAN 500. A backhaul interface to the next-generation core network (NG-CN) 504 may terminate at the ANC. A backhaul interface to the adjacent next-generation access node (NG-AN) may terminate at the ANC. The ANC may include one or more TRPs 508 (which may also be referred to as a BS, NR BS, B-node, 5G NB, AP, gNB, or some other term). As mentioned above, TRPs may be used interchangeably with "cell".

[0076] TRP 508 can be a distributed unit (DU). A TRP can be connected to one ANC (ANC 502) or more ANCs (not described). For example, for RAN sharing, Radio as a Service (RaaS), and service-specific AND deployments, a TRP can be connected to more than one ANC. A TRP can include one or more antenna ports. A TRP can be configured to individually (e.g., dynamically selected) or jointly (e.g., jointly transported) serve traffic to the UE.

[0077] The RAN 500's local architecture can be used to interpret the fronthaul definition. This architecture can be defined as supporting fronthaul solutions across different deployment types. For example, the architecture can be based at least in part on transport network capabilities (e.g., bandwidth, latency, and / or jitter).

[0078] This architecture can share features and / or components with LTE. Depending on various aspects, the next-generation AN (NG-AN)510 can support dual connectivity with NR. For both LTE and NR, the NG-AN can share a common outgoing route.

[0079] This architecture enables collaboration between and within each TRP 508. For example, collaboration can be pre-configured within a TRP and / or across TRPs via ANC 502. Depending on the circumstances, inter-TRP interfaces may be unnecessary or nonexistent.

[0080] Depending on various factors, the RAN 500 architecture allows for dynamic configuration of split logical functions. Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) protocols can be adaptively placed at the ANC or TRP.

[0081] Depending on the aspects, the BS may include a central unit (CU) (e.g., ANC 502) and / or one or more distributed units (e.g., one or more TRP 508).

[0082] As indicated above, Figure 5 This is provided merely as an example. Other examples are possible and may differ from those provided. Figure 5 The example described.

[0083] Figure 6 An example physical architecture of the distributed RAN 600 according to various aspects of this disclosure is described. A centralized core network unit (C-CU) 602 can host core network functions. The C-CU can be deployed centrally. C-CU functionality can be offloaded (e.g., to Advanced Radio Services (AWS)) in an attempt to handle peak capacity.

[0084] The Centralized RAN Unit (C-RU) 604 can store one or more ANC functions. Optionally, the C-RU can store core network functions locally. The C-RU can be deployed in a distributed manner. The C-RU can be located closer to the network edge.

[0085] The Distributed Unit (DU) 606 can store one or more TRPs. The DU can be located at the edge of a network with radio frequency (RF) functionality.

[0086] As indicated above, Figure 6 This is provided merely as an example. Other examples are possible and may differ from those provided. Figure 6 The example described.

[0087] Figure 7A and 7B This is a diagram illustrating example 700 of a network topology for a network according to various aspects of this disclosure. Self-backhaul or integrated access / backhaul (IAB) can be deployed to use a shared set of resources for access and backhaul traffic. For example, a first radio node (e.g., BS110, UE 120, etc.) can communicate backhaul traffic to a second radio node via a first mmWave resource, and can communicate access traffic to a third radio node via a second mmWave resource.

[0088] like Figure 7A As shown, Example 700 may include multiple wireless nodes 702 (e.g., BS) and multiple wireless nodes 704 (e.g., UE). At least one wireless node (e.g., wireless node 702-1) may communicate with the core network via a backhaul link 706 (such as a fiber optic connection, wireless backhaul connection, etc.). Wireless nodes 702 and 704 may communicate with each other using: link sets 708 (such as mmWave link sets); air interfaces such as 3G, 4G, 5G, etc.; and so on. In some aspects, wireless node 702 may correspond to Figure 1 The BS110 or UE 120 shown are examples. Similarly, the wireless node 704 may correspond to... Figure 1The BS110 or UE 120 shown in the figure.

[0089] like Figure 7A As further illustrated, one or more wireless nodes 702 or 704 can communicate indirectly via one or more other wireless nodes 702 or 704. For example, data can be transmitted from the core network to wireless node 704-6 via backhaul link 706, link 708 between wireless node 702-1 and wireless node 702-5, link 708 between wireless node 702-5 and wireless node 702-4, link 708 between wireless node 702-4 and wireless node 704-5, and link 708 between wireless node 704-5 and wireless node 704-6. In some aspects, multiple different paths can be used to transmit data between wireless nodes 702 or 704. For example, wireless node 702-5 may communicate with wireless node 702-4 via a single link 708 (e.g., a direct link) between wireless node 702-5 and wireless node 702-4, and / or via a first link 708 between wireless node 702-5 and wireless node 702-3 and a second link (e.g., an indirect link) between wireless node 702-3 and wireless node 702-4.

[0090] like Figure 7B As shown, wireless nodes 702 and 704 can be arranged in a hierarchical topology to manage network resources. Each link 708 can be associated with a master link endpoint (master LEP) and a slave link endpoint (subordinate LEP), which can define the hierarchy between wireless nodes 702 or 704. For example, wireless node 702-6 can communicate with wireless node 702-7 via link 708-1. In this case, wireless node 702-6 is associated with the master link endpoint of link 708-1, and wireless node 702-7 is associated with the slave link endpoint of link 708-1. This can define wireless node 702-6 as hierarchically superior to wireless node 702-7 and wireless node 702-7 as hierarchically inferior to wireless node 702-6 with respect to link 708-1. Furthermore, wireless node 702-6 can be defined as upstream relative to wireless node 702-7 (while wireless node 702-7 can be defined as downstream relative to wireless node 702-6).

[0091] Similarly, wireless node 702-7 includes the primary link endpoint of link 708-2, while wireless node 702-8 includes the secondary link endpoint of backhaul link 708-2. In this case, with respect to link 708-2, wireless node 702-7 is hierarchically superior to wireless node 702-8 and is upstream of wireless node 702-8, while wireless node 702-8 is hierarchically inferior to wireless node 702-7 and is downstream of wireless node 702-7. In some aspects, wireless node 702 or 704 may include a single antenna or antenna array for both the secondary link endpoint and the primary link endpoint. In some aspects, wireless node 702 or 704 may include a first antenna or antenna array for the secondary link endpoint and a second antenna or antenna array for the primary link endpoint.

[0092] In some respects, radio node 702-6 or the central unit may be referred to herein as an IAB provider. An IAB provider may be a RAN node that provides UE access to the core network and radio backhaul functionality to IAB nodes. Radio nodes 702-7, 702-8, etc., may be referred to as IAB nodes. An IAB node may be associated with a mobile terminal (MT), which may act as a parent IAB node or a UE of the IAB provider. An IAB node may also be associated with a DU or gNB, which may act as a base station for the child nodes of the IAB node (e.g., a gNB, a gNB-DU with a MAC scheduler, etc.).

[0093] As indicated above, Figure 7A and Figure 7B This is provided as an example. Other examples are possible and may differ from those provided. Figure 7A and Figure 7B The example described.

[0094] An upstream wireless node can determine the transmit power of transmissions to each downstream wireless node. Similarly, an upstream wireless node can determine the transmit power of transmissions from each downstream wireless node (e.g., transmissions to an upstream wireless node, transmissions to subsequent downstream wireless nodes, etc.). However, in some network topologies, downstream wireless nodes may experience inter-link interference when receiving multiple transmissions via multiple links (e.g., from multiple upstream wireless nodes, from both upstream and downstream wireless nodes, from multiple downstream wireless nodes, etc.). Furthermore, an upstream or downstream wireless node may be associated with a maximum power threshold (e.g., a maximum transmit power threshold, a maximum receive power threshold, etc.) and may receive instructions to cause transmissions to exceed that maximum power threshold.

[0095] Some aspects described herein enable power control for concurrent reception. For example, a control node can determine multiple powers for multiple transmissions from multiple other wireless nodes and via multiple links to a target wireless node. These multiple powers may include multiple transmit powers of the other wireless nodes, multiple receive powers (e.g., multiple gain values) used by the target wireless node, and so on. These multiple powers can be selected to control inter-link interference and / or satisfy a maximum power criterion. In this scenario, the control node can cause the other wireless nodes to use these multiple powers and transmit the multiple transmissions via the multiple links. In this way, the control node implements communication for specific network topologies such as self-backhaul networks, IAB networks, etc.

[0096] Figure 8A and Figure 8B This is a diagram illustrating example 800 of power control for concurrent reception according to various aspects of this disclosure. (See diagram for example...) Figure 8A and Figure 8B As shown, Example 800 may include a first wireless node 805 and a control node 815, the first wireless node 805 being in communication with a second wireless node 805 via a first link 810 and with a third wireless node 805 via a second link 810.

[0097] In some aspects, radio node 805 may correspond to BS110, UE 120, radio node 702, radio node 704, etc. In some aspects, link 810 may correspond to link 708. In some aspects, control node 815 may correspond to BS110, UE 120, radio node 702, radio node 704, etc. In some aspects, control node 815 may be one or more of the radio nodes 805. For example, control node 815 may be the first radio node 805. In some aspects, control node 815 may be a group of radio nodes, such as one or more of the radio nodes 805, one or more other radio nodes, etc. In some aspects, control node 815 may be a device separate from the radio nodes 805, such as another node in the network, a central unit, an integrated access and backhaul (IAB) provider, a scheduler node, etc.

[0098] At once Figure 8A In this context, the first radio node 805 can be downstream of both the second and third radio nodes 805. For example, the first radio node 805 can be a User Equipment Function (UE-F), while the second and third radio nodes 805 can be Access Node Functions (ANF). In contrast, Figure 8BIn this context, the first wireless node 805 can be downstream of the second wireless node 805 and upstream of the third wireless node 805. For example, the second wireless node 805 can be the ANF of the first wireless node 805, and the first wireless node 805 can be the UE-F of the second wireless node 805; and the first wireless node 805 can be the ANF of the third wireless node 805, and the third wireless node 805 can be the UE-F of the second wireless node 805. In this scenario, the first wireless node 805 can be a relay node. In some aspects, the first wireless node 805 can support concurrent communication with the second and third wireless nodes 805 (e.g., using FDM, spatial division multiplexing (SDM), multi-user MIMO (MU-MIMO), etc.).

[0099] In some respects, wireless node 805 can schedule communication on link 810. For example, regarding... Figure 8A In contrast, the second wireless node 805 can schedule communication on the first link 810, and the third wireless node 805 can schedule communication on the second link 810. Figure 8B In this regard, the second wireless node 805 can schedule communication on the first link 810, and the first wireless node 805 can schedule communication on the second link 810. Although the aspects described herein are based on the first wireless node 805, the second wireless node 805, and the third wireless node 805, the number of other wireless nodes 805, the arrangement of wireless nodes 805, etc., are possible.

[0100] As in Figure 8A and Figure 8B As shown by reference numeral 820 in the accompanying drawings, control node 815 may determine multiple powers for each link 810. For example, control node 815 may determine a first power for a first link 810 and a second power for a second link 810. In some aspects, the multiple powers may be multiple transmit powers. For example, control node 815 may determine a first power that a second wireless node 805 will use to transmit to a first wireless node 805 (e.g., a target wireless node) and a second power that a third wireless node 805 will use to transmit to the first wireless node 805. Additionally or alternatively, the multiple powers may be multiple receive powers. For example, control node 815 may determine a receiver configuration (e.g., the gain configuration of the first wireless node 805) associated with causing the first wireless node 805 to receive concurrent transmissions from the second wireless node 805 and the third wireless node 805 at selected multiple powers. In some aspects, the multiple powers may include one or more transmit powers and one or more receive powers. For example, control node 815 can control the transmit power of a first plurality of transmissions from the first wireless node 805 and the receive power of a second plurality of transmissions to the first wireless node 805.

[0101] In some aspects, control node 815 may select multiple powers for each link 810 to control inter-link interference. For example, control node 815 may select these multiple powers to ensure that a transmission from second wireless node 805 does not interfere with another transmission from third wireless node 805. In some aspects, control node 815 may select multiple powers for each link 810 to meet a maximum power criterion. For example, when first wireless node 805 is about to use a single antenna or antenna array associated with a threshold maximum power to concurrently receive multiple transmissions from second wireless node 805 and third wireless node 805, control node 815 may select these multiple powers to share portions of the available power so that the threshold maximum power is not exceeded.

[0102] In some aspects, control node 815 can statically determine the plurality of powers. For example, control node 815 can be triggered to determine the plurality of powers at specific times, such as during initial configuration, when the first wireless node 805 establishes a connection to the second wireless device and / or the third wireless node 805, etc. In this case, control node 815 can determine the plurality of powers and configure the plurality of powers for subsequent use. In some aspects, control node 815 can semi-statically determine the plurality of powers for a specific type of signal (e.g., for power-sensitive signals such as reference signals). For example, control node 815 can semi-statically determine the plurality of powers for periodic channel state information reference signals (CSI-RS), radio resource management reference signals (RRM RS), etc.

[0103] In some respects, control node 815 can dynamically determine the plurality of powers. For example, after determining a first plurality of powers at a first time, control node 815 can determine a second plurality of powers at a second time, such as based at least in part on changes to network configuration, changes to network characteristics (e.g., signal-to-interference-to-noise ratio, or another network characteristic). Additionally or alternatively, control node 815 can dynamically determine a subset of the plurality of powers. For example, control node 815 can statically determine a first power (e.g., for a first link 810) and can dynamically determine and update a second power (e.g., for a second link 810, another link 810, etc.).

[0104] In some aspects, control node 815 may determine the plurality of powers at least in part based on received signaling. For example, control node 815 may receive signaling from: a central unit (CU) of the network; a wireless node 805 of the network; a group of wireless nodes, which may include a first wireless node 805, a second wireless node 805, or a third wireless node 805; a control node; a scheduler node; and so on. In some aspects, received signaling may include information identifying the plurality of powers. For example, the central unit may provide signaling to control node 815 that specifies the plurality of powers; and control node 815 may cause each wireless node 805 to use the plurality of powers for transmission via each link 810.

[0105] Additionally or alternatively, received signaling may include information related to the plurality of power levels. For example, the scheduler node, the first wireless node 805, the second wireless node 805, the third wireless node 805, etc., may provide information identifying the transmission schedule, and the control node 815 may determine the plurality of power levels at least in part based on the transmission schedule. In some aspects, received signaling may be upper-layer signaling, such as signaling from devices associated with controlling and / or configuring the network.

[0106] In some respects, the control node 815 may determine the plurality of powers based at least in part on stored configuration information. For example, the control node 815 may store static configuration information associated with identifying powers used for the plurality of transmissions, and may determine the plurality of powers based at least in part on the stored static configuration information.

[0107] In some respects, control node 815 can provide signaling related to the plurality of power parameters. For example, control node 815 can provide signaling to scheduler node, central unit, first wireless node 805, second wireless node 805, upper layers of the network (e.g., devices associated with network control, scheduling, and / or configuration), etc., to identify power-related parameters (such as parameters identifying maximum power criteria).

[0108] Additionally or alternatively, control node 815 may provide signaling identifying the plurality of power levels. For example, control node 815 may transmit a power indicator to wireless node 805 or another control node 815, enabling wireless node 805 or the other control node 815 to select an alternative power level to avoid inter-link interference between transmissions. In some aspects, second wireless node 805 may be designated as the primary ANF and may determine the plurality of power levels at least in part based on being designated as the primary ANF and provide control node 815 with signaling associated with the plurality of power levels.

[0109] In some aspects, control node 815 may receive and / or provide signaling identifying configuration parameters, requests for information identifying the configuration parameters, approval of the configuration parameters, disapproval of the configuration parameters, measurements, capability indications, limitation indications, scheduling, etc. For example, control node 815 may request network measurements or indications of the amount of data to be transmitted from first network node 805, receive a response to the request, determine multiple power levels based at least in part on the response and scheduling for first wireless node 805, provide configuration parameters identifying the multiple power levels, and receive an approval message approving the configuration parameters.

[0110] In some respects, the control node 815 may determine the plurality of powers based at least in part on the characteristics of the network, the devices in the network, the traffic being transmitted through the network, and so on. For example, the control node 815 may determine the plurality of powers based at least in part on the following: the type of signal to be transmitted, the type of wireless node (e.g., the type of first wireless node 805, second wireless node 805, third wireless node 805, etc.), the state of the wireless node (the state of first wireless node 805, second wireless node 805, third wireless node 805, etc.), the timing of the signal, the angular direction of the signal, the channel used for transmission or the configuration of the signal for transmission, the priority of the channel used for transmission or the signal for transmission, and so on.

[0111] In some respects, control node 815 may determine a power range. For example, control node 815 may determine a maximum transmission power at least in part based on, for example, the type of signal or channel for transmission, and may provide information identifying the maximum power so that, for example, a second wireless node 805 or a third wireless node 805 can configure the transmission to a power lower than the maximum power. Additionally or alternatively, control node 815 may determine a minimum transmission power and may provide information identifying the minimum power.

[0112] In some aspects, control node 815 may determine the plurality of powers based at least in part on priority ranking. For example, control node 815 may determine that control signals are associated with a priority ranking higher than payload signals; scheduling requests are associated with a priority ranking higher than channel state information signals, data signals, and probe reference signals; and so on. Additionally or alternatively, control node 815 may determine the priority ranking of the portions of the allocated available power based at least in part on whether radio node 805 is included in a primary or secondary cell group, whether it is included in the upstream or downstream direction, and so on. In some aspects, control node 815 may scale the power to determine the plurality of powers. For example, based at least in part on the maximum power and the relative priority ranking associated with the first link 810 and the second radio node 805, and the second link 810 and the third radio node 805, control node 815 may scale the maximum power to allocate the maximum power or avoid inter-link interference.

[0113] In some respects, power-related signaling can be specific types of signals. For example, control node 815 may receive or provide downlink control information (DCI) signals, uplink control information (UCI) signals, media access control (MAC) control element (CE) signals, radio resource control (RRC) signals, master information block (MIB) signals, system information block (SIB) signals, reference signals (e.g., synchronization signals, beam reference signals, physical downlink shared channel (PDSCH) signals, confirmation signals, negative confirmation signals, power indication signals, upper-layer signaling signals, F1-AP signals, modulation and coding scheme (MCS) indication signals, etc.), and so on. In this case, control node 815 may receive feedback information (e.g., identifying MCS, maximum received power, etc.) from first radio node 805 and may determine the power at least in part based on this feedback information. Similarly, the control node 815 may receive feedback information from the first wireless node 805 indicating a request to associate a transmission with greater power, and may determine the plurality of powers to increase subsequent transmit power and / or subsequent receive power.

[0114] In some aspects, control node 815 can determine the power without receiving signaling from first wireless node 805. For example, when second wireless node 805 and third wireless node 805 are scheduling nodes, the second wireless node 805 and third wireless node 805 (e.g., control node 815) can exchange one or more messages to determine the transmit power used to transmit to first wireless node 805 without causing inter-link interference or exceeding the maximum transmit power criterion. In some aspects, the first power can be determined at least in part based on the second power. For example, when first wireless node 805 is the scheduling node of second link 810 and is a scheduled node of first link 810, control node 815 can determine the power used for the first link at least in part based on the power used for the second link.

[0115] In some aspects, control node 815 may determine the receiver configuration of first wireless node 805 such that first wireless node 805 can receive transmissions from second wireless node 805 and third wireless node 805 via each link 810. For example, control node 815 may determine receiver power configuration, low-noise amplifier (LNA) gain configuration, receiver filter configuration, analog or digital beamforming configuration, etc. In this case, control node 815 may determine multiple powers (e.g., multiple gain values) of the LNA of first wireless node 805 and may cause first wireless node 805 to use these multiple powers of the LNA to receive multiple transmissions. Similarly, control node 815 may cause first wireless node 805 to adjust beamforming configuration to change the relative received power between each link 810.

[0116] In some aspects, these multiple powers can be selected to suppress the received power transmitted via link 810. For example, control node 815 can determine the power configured for the receiver so that the received power of the transmission is suppressed to avoid inter-link interference or to meet a maximum power criterion. In some aspects, control node 815 can adjust the receiver configuration at least in part based on a priority order associated with the second wireless node 805, the first link 810, the third wireless node 805, the second link 810, and so on.

[0117] In some aspects, control node 815 may determine additional powers used by first wireless node 805 for transmission to second wireless node 805 and / or third wireless node 805. For example, control node 815 may determine a first transmit power for a first link 810 to second wireless node 805, a second transmit power for a second link 810 to third wireless node 805, a first receive power for the first link 810 from second wireless node 805, and a second receive power for the second link 810 from third wireless node 805. In this way, control node 815 (e.g., first wireless node 805) can enable first wireless node 805 to receive and provide concurrent transmissions without inter-link interference or exceeding maximum transmit power criteria. In some aspects, control node 815 may control the transmit power used for accessing the link based at least in part on backhaul communication with its parent node.

[0118] As in Figure 8A and Figure 8B As further illustrated by reference numeral 825, control node 815 enables the use of multiple powers for transmission, and as illustrated by reference numeral 830, second wireless node 805 and third wireless node 805 can use these multiple powers for transmission. For example, first wireless node 805 can use a first power to receive information from second wireless node 805 via a first link 810, and can concurrently use a second power to receive information from third wireless node 805 via a second link 810. In some aspects, control node 815 can transmit signaling (e.g., identifying power, power-related receiver configuration, etc.) to wireless node 805 to enable transmissions such as to first wireless node 805, second wireless node 805, third wireless node 805, etc. In this way, control node 815 enables first wireless node 805 to receive multiple concurrent transmissions without excessive inter-link interference, without exceeding the dynamic range or detection range associated with the maximum received power criterion, etc. Furthermore, the control node 815 enables the first wireless node 805 to transmit multiple concurrent transmissions without excessive inter-link interference, without exceeding the maximum transmit power criterion, etc.

[0119] In some aspects, the first wireless node 805 may use the multiple powers to receive payload data. Additionally or alternatively, the first wireless node 805 may use the multiple powers to receive signaling data. In some aspects, the first wireless node 805 may receive reference signals. For example, when multiple concurrent reference signals (such as those at least partially based on beam sweep) are received, the second wireless node 805 and / or the third wireless node 805 may dynamically adjust the power used for each reference signal, at least partially based on the multiple powers.

[0120] In some respects, the first wireless node 805 can transmit relayed signals. For example, the first wireless node 805 can operate in a different frequency, RAT, cell, etc., than the direct link between the second and third wireless nodes 805 to relay signals (e.g., an indirect link) between the second and third wireless nodes 805. In this case, the first wireless node 805 can use power from among the multiple powers to retransmit the relayed signal to achieve redundant communication between the second and third wireless nodes 805. In this case, the control node 815 can indicate to the first wireless node 805, the second wireless node 805, the third wireless node 805, etc., the power available for use in the direct and / or indirect links.

In some aspects, the first power among the plurality of powers is statically determined, while the second power among the plurality of powers is dynamically determined. In some aspects, the power among the plurality of powers is determined at least in part based on the following: the type of signal to be transmitted on the links among the plurality of links, the type of the target wireless node, the type of another wireless node, the state of the target wireless node, the state of the other wireless node, the timing of the signal to be transmitted on the link among the plurality of links, or the angular direction of the signal to be transmitted on the link among the plurality of links, the channel for transmission on the link among the plurality of links or the configuration of the signal for transmission, the capability of at least one wireless node, the priority of the channel or the signal for transmission on the link among the plurality of links, etc.

[0130] In some aspects, the control node may determine the maximum power of transmission using one of the plurality of links, and this maximum power may be determined at least in part based on at least one of the signal type used for transmission using the link or the channel type associated with the link.
