[0002] This patent application claims priority to Greek patent application No. 20200100540, filed on September 4, 2020, entitled “SEPARATE UPLINK RESOURCES FOR FEEDBACK REPORT AND CHANNEL STATE INFORMATION REPORT WITH BEAMSWEEPING,” which has been assigned to the assignee of this application. The disclosure of the prior application is considered part of this patent application and is incorporated herein by reference. Technical Field
[0003] In summary, various aspects of this disclosure relate to wireless communication, and particularly to techniques and apparatuses for separate uplink resources for feedback reporting and channel state information (CSI) reporting using beam scanning. Background Technology
[0004] 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 enable 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 / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).
[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, while an "uplink" (or "backlink") 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 Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.
[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be referred to as 5G) is an enhancement set of the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), thereby better supporting mobile broadband internet access, as well as beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other wireless access technologies remain useful. Summary of the Invention

[0011] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a UE, cause the UE to: receive a DCI indicating a first uplink resource for ACK / NACK feedback reporting and a second uplink resource for CSI reporting; and receive, via the DCI, an indication of a first beam scanning mode associated with the first uplink resource and a second beam scanning mode associated with the second uplink resource.
[0012] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a base station, cause the base station to: send a DCI to a UE, the DCI indicating a first uplink resource for ACK / NACK feedback reporting and a second uplink resource for CSI reporting; and send, via the DCI, to the UE, an indication of a first beam scanning mode associated with the first uplink resource and a second beam scanning mode associated with the second uplink resource.

[0026] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented 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 on the teachings herein, those skilled in the art will understand 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, an apparatus or a method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.
[0027] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings, through various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.
[0028] It should be noted that while this document may use terms commonly associated with 5G or NR Radio Access Technologies (RATs) to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).
[0029] Figure 1This is a diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. Wireless network 100 may include multiple base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, Transmit / Receive Point (TRP), etc. Each BS can 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.
[0030] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c 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,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.
[0031] 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, any suitable transport network can be used to interconnect BSs with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (such as direct physical connections or virtual networks).
[0032] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit 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 BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, repeater, etc.
[0033] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).
[0034] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.
[0035] 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 device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, or satellite radio unit, etc.), 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.
[0036] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which 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 cellular networks) 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 housing the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0037] Typically, 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.
[0038] 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 communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols) and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described herein as being performed by base station 110.
[0039] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) (spanning from 410 MHz to 7.125 GHz), and / or can communicate using an operating band with a second frequency range (FR2) (spanning from 24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency (IF) bands. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "below 6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it differs from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as "millimeter wave" by the International Telecommunication Union (ITU). Therefore, unless otherwise explicitly stated, it should be understood that the terms "below 6 GHz" and the like (if used herein) can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., below 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0040] As pointed out above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.
[0041] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally, T ≥ 1 and R ≥ 1.
[0042] At base station 110, transmitting processor 220 can receive data 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., code 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. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM) process its corresponding output symbol stream 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.
[0043] 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 adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, Received Signal Strength Indicator (RSSI) parameter, Reference Signal Received Quality (RSRQ) parameter, and / or CQI parameter, as well as other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.
[0044] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.
[0045] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, and other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.
[0046] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264 and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 5-9 (Described).
[0047] 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 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., as referenced). Figure 5-9 (Described).
[0048] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other components may perform one or more techniques associated with separate uplink resources for feedback reporting and CSI reporting utilizing beam scanning, 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 can perform or direct, for example Figure 6 Process 600 Figure 7 The operation of process 700 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. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or instruct, for example... Figure 6 Process 600 Figure 7 The operation of process 700 and / or other processes as described herein. In some aspects, execution instructions may include run instructions, translation instructions, compilation instructions and / or interpretation instructions, and other examples.

[0073] Although Figure 2 The boxes in the diagram are shown as different components, but the functions described above with respect to these boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components.

[0074] As pointed out above, Figure 2This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.
[0075] Figure 3 This is a diagram illustrating example 300 of a DCI that schedules multiple communications according to various aspects of this disclosure. Figure 3 As shown, base station 110 and UE 120 can communicate with each other. In some aspects, base station 110 and UE 120 can be included in a wireless network (such as wireless network 100). Base station 110 and UE 120 can communicate on a radio access link, which can include an uplink and a downlink.
[0076] Base station 110 can send Physical Downlink Control Channel (PDCCH) communication 305, including DCI, to UE 120. DCI can schedule multiple communications for UE 120. For example, DCI can schedule the transmission of CSI Reference Signal (CSI-RS) 310. CSI-RS 310 can be aperiodic CSI-RS because CSI-RS 310 is dynamically triggered by DCI in PDCCH communication 305. In some aspects, CSI-RS 310 can carry information for downlink channel estimation (e.g., downlink CSI acquisition), which can be used for scheduling, link adaptation, or beam management, and other examples. Base station 110 can configure a set of CSI-RS for UE 120, and UE 120 can measure the configured set of CSI-RS. Based at least in part on measurements, UE 120 can perform channel estimation and can report channel estimation parameters to base station 110 (e.g., in a CSI report), such as CQI, precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), layer indicator (LI), rank indicator (RI), or RSRP, and other examples. Base station 110 can use the CSI report to select transmission parameters for downlink communication to UE 120, such as the number of transport layers (e.g., rank), precoding matrix (e.g., precoder), MCS, and / or refined downlink beam (e.g., using a beam refinement process or beam management process), and other examples.
[0077] The DCI included in the PDCCH communication 305 can also schedule data communications, such as Physical Downlink Shared Channel (PDSCH) communication 315. PDSCH communication 315 can be dynamically permitted PDSCH communication because it is triggered or scheduled by the DCI included in the PDCCH communication 305.
[0078] In Example 300, the DCI included in PDCCH communication 305 may also indicate scheduling information for uplink communication to be transmitted by UE 120. The scheduling information may indicate resources to be used for acknowledgment (ACK) or negative acknowledgment (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) associated with communication scheduled by the DCI. For example, the scheduling information may indicate one or more uplink resources for ACK / NACK feedback 320 associated with PDSCH communication 315. The one or more uplink resources used for ACK / NACK feedback 320 may be uplink control resources (e.g., one or more Physical Uplink Control Channel (PUCCH) resources, etc.). For example, ACK / NACK feedback 320 may be indicated in uplink control information (UCI) carried on the PUCCH resource.
[0079] In some aspects, the scheduling information in the DCI can indicate one or more uplink resources for CSI report 325. CSI report 325 can indicate one or more of the aforementioned channel estimation parameters to base station 110. In some aspects, the one or more uplink resources for CSI report 325 can be the same as the one or more uplink resources for ACK / NACK feedback 320 (e.g., both ACK / NACK feedback 320 and CSI report 320 can be included in the same uplink resource). In some aspects, the one or more uplink resources for CSI report 325 can be different from the one or more uplink resources for ACK / NACK feedback 320 (e.g., PUCCH resources can be used to send ACK / NACK feedback 320, and Physical Uplink Shared Channel (PUSCH) resources or different PUCCH resources can be used to send CSI report).
[0080] In some cases, scheduling information in the DCI can be indicated once and reused for multiple communications. For example, the DCI can schedule multiple semi-persistent or periodic downlink communications. The scheduling information can indicate uplink resources for ACK / NACK feedback 320 for semi-persistent or periodic downlink communications. UE 120 can reuse the scheduling information for ACK / NACK feedback 320 at each instance of semi-persistent or periodic downlink communication. Similarly, UE 120 can reuse scheduling information associated with CSI report 325 for future CSI reports. In this way, base station 110 and UE 120 can save signaling overhead associated with scheduling communications.
[0081] As pointed out above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.
[0082] Figure 4 This is a diagram illustrating example 400 of communication between a base station and a UE using beamforming according to various aspects of this disclosure. Figure 4 As shown, base station 110 and UE 120 can communicate with each other. In some aspects, base station 110 and UE 120 can be included in a wireless network (such as wireless network 100). Base station 110 and UE 120 can communicate on a radio access link, which can include an uplink and a downlink.
[0083] Base station 110 can transmit to UE 120 located within its coverage area. Base station 110 and UE 120 can be configured for beamforming communication, wherein base station 110 can use a directional base station transmit beam to transmit in the direction of UE 120, and UE 120 can use a directional UE receive beam to receive the transmission. Each base station transmit beam may have an associated beam ID, beam direction, or beam symbol, and other examples. Base station 110 can transmit downlink communication via one or more base station transmit beams 405.
[0084] UE 120 may attempt to receive downlink transmissions via one or more UE receive beams 410, which may be configured at the UE 120's receive circuitry using different beamforming parameters. UE 120 may identify specific base station transmit beams 405 (shown as base station transmit beam 405-A) and specific UE receive beams 410 (shown as UE receive beam 410-A) that offer relatively advantageous performance (e.g., having the best channel quality with a combination of different measurements of base station transmit beams 405 and UE receive beams 410). In some examples, UE 120 may send an indication of which base station transmit beam 405 is identified by UE 120 as the preferred base station transmit beam, which base station 110 may select for transmissions to UE 120. Therefore, UE 120 can acquire and maintain a beam-to-link (BPL) with base station 110 for downlink communication (e.g., a combination of base station transmit beam 405-A and UE receive beam 410-A), which can be further refined and maintained according to one or more established beam refinement processes.
[0085] Downlink beams (such as base station transmit beam 405 or UE receive beam 410) may be associated with a Transmission Configuration Indicator (TCI) state. The TCI state may indicate the directivity or characteristics of the downlink beam, such as one or more quasi-co-location (QCL) attributes of the downlink beam. QCL attributes may include, for example, Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, and other examples. In some examples, each base station transmit beam 405 may be associated with a Synchronization Signal Block (SSB), and UE 120 may indicate a preferred base station transmit beam 405 by transmitting uplink transmissions in the resources of the SSB associated with the preferred base station transmit beam 405. A particular SSB may have an associated TCI state (e.g., for antenna port or for beamforming). In some examples, base station 110 may indicate the downlink base station transmit beam 405 at least in part based on antenna port QCL attributes that can be indicated by the TCI state. The TCI state can be associated with a set of downlink reference signals (e.g., SSB and aperiodic, periodic, or semi-persistent CSI-RS) for different QCL types (e.g., different combinations of QCL types for Doppler shift, Doppler spread, average delay, delay spread, or spatial reception parameters, and other examples). In the case where the QCL type indicates spatial reception parameters, the QCL type can correspond to the analog receive beamforming parameters of the UE receive beam 410 at UE 120. Therefore, UE 120 can select the corresponding UE receive beam 410 from the BPL set, at least in part, based on the base station transmit beam 405 indicated by base station 110 via TCI indication.
[0086] Base station 110 can maintain an active TCI state set for downlink shared channel transmission and an active TCI state set for downlink control channel transmission. The active TCI state set for downlink shared channel transmission can correspond to the beams used by base station 110 for downlink transmission on PDSCH. The active TCI state set for downlink control channel communication can correspond to the beams that base station 110 can use for downlink transmission on PDCCH or in a control resource set (CORESET). UE 120 can also maintain active TCI state sets for receiving downlink shared channel transmission and CORESET transmission. If a TCI state is activated for UE 120, UE 120 can have one or more antenna configurations that are at least partially based on the TCI state, and UE 120 may not need to reconfigure antennas or antenna weighting configurations. In some examples, the active TCI state sets for UE 120 (e.g., active PDSCH TCI state and active CORESET TCI state) can be configured by configuration messages such as RRC messages.
[0087] Similarly, for uplink communication, UE 120 can use a directional UE transmit beam to transmit in the direction of base station 110, and base station 110 can use a directional base station receive beam to receive the transmission. Each UE transmit beam may have an associated beam ID, beam direction, or beam symbol, and other examples. UE 120 may transmit uplink communication via one or more UE transmit beams 415.
[0088] Base station 110 can receive uplink transmissions via one or more base station receive beams 420. Base station 110 can identify specific UE transmit beams 415 (shown as UE transmit beam 415-A) and specific base station receive beams 420 (shown as base station receive beam 420-A) that provide relatively advantageous performance (e.g., optimal channel quality with a combination of different measurements of UE transmit beam 415 and base station receive beam 420). In some examples, base station 110 can send an indication of which UE transmit beam 415 base station 110 identifies as the preferred UE transmit beam, which base station 110 can select for transmissions from UE 120. UE 120 and base station 110 can thus acquire and maintain a BPL (e.g., a combination of UE transmit beam 415-A and base station receive beam 420-A) for uplink communication, which can be further refined and maintained according to one or more established beam refinement processes. Uplink beams (such as UE transmit beam 415 or base station receive beam 420) can be associated with spatial relationships. Spatial relationships can indicate the directionality or characteristics of the uplink beam, similar to one or more QCL attributes as described above. In some aspects, uplink beams can be associated with uplink TCI states (e.g., in a manner similar to that described above with respect to downlink TCI states).
[0089] As pointed out above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.
[0090] In some cases, communication within a wireless network (such as Wireless Network 100) may be associated with stringent latency and / or reliability requirements. For example, services provided by Ultra Reliable Low Latency Communication (URLLC) services, services associated with Industrial Internet of Things (IIoT) scenarios, services associated with factory automation, and other example use cases may be associated with latency and / or reliability requirements.
[0091] In some cases, a single DCI communication can schedule ACK / NACK feedback reports and aperiodic CSI reports on separate uplink resources (e.g., as mentioned above regarding...). Figure 3 (Described). In some cases, successful transmission of ACK / NACK feedback reports and / or CSI reports may be important to ensure that reliability and / or latency requirements for communication are met. For example, if UE 120 fails to send an ACK / NACK feedback report, base station 110 may not know whether downlink communication was successfully transmitted (or there may be a delay in notifying base station 110 of whether downlink communication was successfully transmitted, which is associated with retransmission of the ACK / NACK feedback report). Therefore, if ACK / NACK feedback reports and / or CSI reports are not successfully transmitted, latency and / or reliability requirements for communication within the network may not be met.
[0092] Some of the techniques and apparatus described herein enable the use of beam scanning to allocate separate uplink resources for ACK / NACK feedback reports and CSI reports. For example, a single DCI scheduling ACK / NACK feedback reports and CSI reports on different uplink resources can also indicate a first beam scanning mode for transmitting ACK / NACK feedback reports and a second beam scanning mode for transmitting CSI reports. The beam scanning mode can indicate the set of beams to be used for transmitting communications. Therefore, by using beam scanning modes to transmit uplink communications (e.g., ACK / NACK feedback reports and CSI reports) (e.g., by transmitting uplink communications on multiple uplink transmit beams), the reliability of uplink communications is improved.
[0093] Furthermore, the beam scanning pattern specified for each uplink resource provides additional flexibility, enabling UE 120 and base station 110 to conserve resources associated with transmitting uplink resources. For example, ACK / NACK feedback reports and CSI reports can be associated with different importance levels for latency and / or reliability requirements for maintaining communication within the network. Base station 110 can configure a first uplink resource with a robust beam scanning pattern (e.g., using more beams, more repetitions, stronger uplink transmit power, and other examples) to improve the reliability of communication transmitted on the first uplink resource (e.g., ACK / NACK feedback reports). Base station 110 can configure a second uplink resource with a less robust beam scanning pattern (e.g., using fewer beams, fewer repetitions, and / or lower uplink transmit power, and other examples) to conserve resources associated with transmitting communication on the second uplink resource (e.g., CSI reports) (e.g., where communication transmitted on the second uplink resource is associated with lower importance for latency and / or reliability requirements for maintaining communication within the network). Additionally, it improves the reliability of communication (e.g., CSI reports) on the second uplink resource (compared to sending the communication without using beam scanning).
[0094] If base station 110 fails to receive communication transmitted on the second uplink resource, base station 110 can reschedule the transmission of that communication using a good beam (e.g., a beam associated with higher signal strength or signal quality) identified in the transmission of communication on the first uplink resource (e.g., using a more robust beam scanning mode). In this way, base station 110 and UE 120 can conserve resources while ensuring that latency and / or reliability requirements for communication within the network are met.
[0095] Figure 5 This is a diagram illustrating example 500 associated with separate uplink resources for feedback reporting and CSI reporting utilizing beam scanning, according to various aspects of this disclosure. Figure 5 As shown, base station 110 and UE 120 can communicate with each other. In some aspects, base station 110 and UE 120 can be included in a wireless network (such as wireless network 100). In some aspects, the wireless network can be an IIoT wireless network. Base station 110 and UE 120 can communicate on a wireless access link, which can include an uplink and a downlink.
[0096] As indicated by reference numeral 505, base station 110 can transmit, and UE 120 can receive, a DCI indicating a first uplink resource for ACK / NACK feedback reporting and a second uplink resource for CSI reporting. The first and second uplink resources can be different uplink resources. The uplink resources (e.g., the first and / or second uplink resources) can be PUCCH or PUSCH resources. In some aspects, the CSI report can be an aperiodic CSI report (e.g., triggered by a DCI that schedules the transmission of aperiodic CSI-RS).
[0097] DCI can schedule base station 110 for downlink data communication (e.g., PDSCH communication) and aperiodic CSI-RS transmission. ACK / NACK feedback reports can be associated with downlink data communication. CSI reports can be associated with aperiodic CSI-RS. In some aspects, DCI can be related to the above regarding... Figure 3 The same (or similar) manner described is used to schedule downlink data communication, aperiodic CSI-RS, ACK / NACK feedback reports and / or CSI reports.
[0098] The DCI can indicate a first beam scanning mode associated with a first uplink resource and a second beam scanning mode associated with a second uplink resource. The beam scanning mode (e.g., the first beam scanning mode and / or the second beam scanning mode) can indicate the set of beams that the UE 120 will use to transmit communication on the associated uplink resource. In some aspects, the first beam scanning mode can be the same as the second beam scanning mode (e.g., the DCI can indicate the same beam scanning mode for both the first and second uplink resources, and / or the DCI can indicate a single beam scanning mode and indicate that the single beam scanning mode will be used for both the first and second uplink resources). In some aspects, the first beam scanning mode can be different from the second beam scanning mode.
[0099] In some respects, the first beam scanning mode used to send ACK / NACK feedback reports can be more robust than the second beam scanning mode used to send CSI reports. For example, compared to the second beam scanning mode, the first beam scanning mode can be associated with more beams, more repetition, stronger uplink transmit power, and other examples. In this way, the reliability of the ACK / NACK feedback reports is increased. Furthermore, compared to the first beam scanning mode, resources associated with sending CSI reports can be saved (e.g., because CSI reports may be less important for maintaining latency and / or reliability requirements of communication within the network), while also improving the reliability of CSI reports compared to sending CSI reports without utilizing beam scanning.
[0100] In some aspects, the beam scanning mode can be a time division multiplexing (TDM) beam scanning mode, a frequency division multiplexing (FDM) beam scanning mode, and / or a space division multiplexing (SDM) beam scanning mode. For example, the beam scanning mode can be a TDM mode, an FDM mode, and / or an SDM mode that spans multiple beams. In some aspects, the beams included in the beam scanning mode can be indicated by spatial relation information and / or uplink TCI status, and other examples.
[0101] In some aspects, the beam scanning mode can indicate that the beams included in the beam scanning mode will be repeated in different time-domain resources (e.g., in different symbols) and / or in different frequency-domain resources (e.g., in different resource blocks).
[0102] In some aspects, uplink resources (e.g., a first uplink resource and / or a second uplink resource) may include a single uplink resource or multiple uplink resources. When an uplink resource comprises a single uplink resource, the beam scanning pattern associated with the uplink resource may indicate that different beams occupy different portions of the uplink resource (e.g., different time-domain resources, different frequency-domain resources, and / or different spatial-domain resources). For example, the beam scanning pattern may indicate a first beam and a second beam. The beam scanning pattern may indicate that the first beam occupies a first set of resources associated with the uplink resource (e.g., a first time-domain resource, a first frequency-domain resource, and / or a first spatial-domain resource). The beam scanning pattern may indicate that the second beam occupies a second set of resources associated with the uplink resource (e.g., a second time-domain resource, a second frequency-domain resource, and / or a second spatial-domain resource).
[0103] In some aspects, an uplink resource comprising only a single uplink resource (e.g., a first uplink resource and / or a second uplink resource) can be associated with a single downlink path loss reference signal. For example, base station 110 can indicate (e.g., in DCI or in another downlink communication) the downlink path loss reference signal associated with the uplink resource. Base station 110 can transmit, and UE 120 can receive, the downlink path loss signal. UE 120 can use the downlink path loss reference signal to determine the uplink transmit power associated with the uplink resource. Therefore, the same uplink transmit power can be used to transmit all beams associated with the uplink resource.
[0104] In cases where an uplink resource (e.g., a first uplink resource and / or a second uplink resource) comprises multiple uplink resources, the beam scanning mode associated with the uplink resource can indicate the beam set for each of the multiple uplink resources. In other words, the beam scanning mode can indicate the beams used for each of the multiple uplink resources in a manner similar to that described above with respect to a single uplink resource (e.g., each of the multiple uplink resources can be associated with a beam set occupying different resources within the uplink resources). In some aspects, each of the multiple uplink resources can be associated with a downlink path loss reference signal (e.g., the first uplink resource and / or the second uplink resource can be associated with multiple downlink path loss reference signals corresponding to the multiple uplink resources).
[0105] For example, base station 110 may indicate (e.g., in DCI or in another downlink communication) multiple downlink path loss reference signals associated with uplink resources (e.g., a first uplink resource and / or a second uplink resource). Base station 110 may transmit, and UE 120 may receive, the downlink path loss reference signals. UE 120 may use the downlink path loss reference signals to determine the uplink transmit power associated with a corresponding uplink resource among the multiple uplink resources. Therefore, when the first uplink resource and / or the second uplink resource comprises multiple uplink resources, the uplink transmit power can be determined based on each uplink resource.
[0106] In some aspects, the DCI can adequately indicate the beam scanning mode (e.g., a first beam scanning mode and / or a second beam scanning mode). For example, the beam scanning mode can be associated with a set of parameters such as uplink resource type (e.g., PUCCH and / or PUSCH), uplink resource identifier, number of uplink resources, resource allocation for each uplink resource, number of repetitions for each uplink resource, UE panel identifier for each beam, and / or downlink path loss reference signal for each uplink resource, and other examples. In some aspects, the DCI can indicate all parameters associated with the beam scanning mode (e.g., a first beam scanning mode and / or a second beam scanning mode).
[0107] In some respects, the DCI can partially indicate the beam scanning mode. For example, a subset of parameters for the beam scanning mode can be configured by base station 110 using RRC signaling. The remaining parameters of the beam scanning mode (e.g., parameters configured without using RRC signaling) can be indicated by the DCI.
[0108] In some aspects, base station 110 can use RRC signaling to configure UE 120 with multiple beam scanning modes. For example, base station 110 can indicate multiple beam scanning modes (e.g., indicate a set of parameters associated with each beam scanning mode). Base station 110 can indicate an index value associated with each of the multiple beam scanning modes. DCI can indicate beam scanning modes (e.g., a first beam scanning mode and / or a second beam scanning mode) by indicating the index value associated with the beam scanning mode. Base station 110 can use MAC-CE signaling or DCI signaling to dynamically update the beam scanning modes configured by RRC. For example, base station 110 can use MAC-CE signaling and / or DCI signaling to change (e.g., add or remove) the uplink resources associated with the beam scanning modes.
[0109] As indicated by reference numeral 510, base station 110 can transmit and UE 120 can receive downlink data communications (e.g., dynamically permitted PDSCH communications) scheduled by DCI. As indicated by reference numeral 515, base station 110 can transmit and UE 120 can receive aperiodic CSI-RS scheduled by DCI.
[0110] As indicated by reference numeral 520, UE 120 can transmit an ACK / NACK feedback report associated with downlink data communication on a first uplink resource according to a first beam scanning mode. For example, UE 120 can determine whether the downlink data communication has been successfully received (e.g., at least in part based on an attempt to decode the downlink data communication). If UE 120 determines that the downlink data communication has been successfully received, UE 120 can transmit ACK feedback on the first uplink resource according to the first beam scanning mode. If UE 120 determines that the downlink data communication has not been successfully received, UE 120 can transmit NACK feedback on the first uplink resource according to the first beam scanning mode. As described above, UE 120 can determine one or more uplink transmit powers for transmitting the ACK / NACK feedback report based at least in part on one or more downlink path loss reference signals associated with the first uplink resource.
[0111] As indicated by reference numeral 525, UE 120 can transmit CSI reports on the second uplink resource according to the second beam scanning mode. For example, UE 120 can receive aperiodic CSI-RS. UE 120 can use one or more UE receive beams to measure the aperiodic CSI-RS. Based at least in part on the measurement, UE 120 can perform channel estimation and can report channel estimation parameters (e.g., in the CSI report) to base station 110. As described above, UE 120 can determine one or more uplink transmit powers for transmitting CSI reports based at least in part on one or more downlink path loss reference signals associated with the second uplink resource.
[0112] As indicated by reference numeral 530 in the attached figure, base station 110 can determine that a CSI report has not been successfully received. For example, base station 110 can attempt to receive an ACK / NACK feedback report and a CSI report. Base station 110 can determine that at least one of the ACK / NACK feedback report or the CSI report has not been successfully received. Therefore, base station 110 can determine that UE 120 should retransmit the uplink communication that has not been successfully received.
[0113] As indicated by reference numeral 535, base station 110 may determine one or more beams (e.g., one or more BPLs, one or more UE transmit beams, and / or one or more base station receive beams) to be used for retransmission of CSI reports that base station 110 has not yet successfully received. In some aspects, base station 110 may determine one or more beams at least in part based on the reception of ACK / NACK feedback reports. For example, base station 110 may successfully receive ACK / NACK feedback reports and may not successfully receive CSI reports. Base station 110 may identify one or more good beams (e.g., beams associated with good channel estimation parameters, and / or beams on which ACK / NACK feedback reports are successfully transmitted, and other examples) at least in part based on the reception of ACK / NACK feedback reports. Base station 110 may determine that the CSI report will be retransmitted by UE 120 using one or more good beams identified from the reception of ACK / NACK feedback reports. If the CSI report is successfully received but the ACK / NACK feedback report is not successfully received, base station 110 may determine one or more beams for the transmission of the ACK / NACK feedback report in a similar manner (e.g., at least in part based on one or more good beams associated with the reception of the CSI report). In some aspects, base station 110 may determine different beam scanning modes (e.g., a third beam scanning mode) that include one or more beams to be used for retransmissions of uplink communications that base station 110 has not yet successfully received. The different beam scanning modes may indicate one or more beams included in a first beam scanning mode (e.g., the beam scanning mode for transmitting successfully received ACK / NACK feedback reports).
[0114] As indicated by reference numeral 540, base station 110 can transmit, and UE 120 can receive, an indication of one or more beams to be used for retransmission of a CSI report that base station 110 has not yet successfully received. For example, base station 110 can reschedule the CSI report and indicate one or more beams to be used for retransmission of uplink communication. In some aspects, base station 110 can indicate a different beam scanning mode (e.g., a third beam scanning mode) associated with retransmission of uplink communication that base station 110 has not yet successfully received. In some aspects, base station 110 can indicate one or more uplink resources and one or more beams to be used for retransmission of uplink communication that base station 110 has not yet successfully received. In some aspects, base station 110 can indicate one or more uplink resources and one or more beams to be used for retransmission of uplink communication in DCI communication. As indicated by reference numeral 545, UE 120 can use one or more beams (or different beam scanning modes) indicated by base station 110 to transmit a retransmission of the CSI report, and base station 110 can receive the retransmission.
[0115] Therefore, by using a beam scanning pattern to transmit uplink communication (e.g., ACK / NACK feedback reports and CSI reports) (e.g., by transmitting uplink communication on multiple uplink transmit beams), the reliability of uplink communication is improved. Furthermore, the beam scanning pattern indicating each uplink resource provides additional flexibility, allowing UE 120 and base station 110 to conserve resources associated with transmitting uplink resources (e.g., where ACK / NACK feedback reports and CSI reports are associated with different importance levels for maintaining latency and / or reliability requirements within the network). Configuring a first uplink resource with a more robust beam scanning pattern (e.g., using more beams, more repetitions, stronger uplink transmit power, and other examples) and a second uplink resource with a less robust beam scanning pattern (e.g., using fewer beams, fewer repetitions, and / or lower uplink transmit power, and other examples) saves resources associated with transmitting communication (e.g., CSI reports) on the second uplink resource (e.g., where the communication transmitted on the second uplink resource is associated with lower importance for maintaining latency and / or reliability requirements for communication within the network) (compared to transmitting communication on the first uplink resource using the more robust beam scanning pattern). Additionally, the reliability of communication (e.g., CSI reports) on the second uplink resource is improved (compared to transmitting the communication without beam scanning). In this way, base station 110 and UE 120 can save resources while ensuring that latency and / or reliability requirements for communication within the network are met.
