Description

[0001] Cross - reference to related applications

[0002] This patent application claims the priority and benefit of pending non - provisional application No. 17 / 316,340, filed on May 10, 2021, and provisional application No. 63 / 023,175, filed on May 11, 2020, in the United States Patent Office, and assigned to the assignee hereof, and is hereby expressly incorporated herein by reference in its entirety as if fully set forth below and for all applicable purposes. Technical Field

[0003] The techniques discussed below generally relate to wireless communication networks, and more specifically, to measurement reports in non - beam - based and beam - based communication scenarios (e.g., millimeter - wave beams). Some examples and techniques enable and provide communication devices, methods, and systems configured for techniques for strategically configuring measurement reports (e.g., measurement report size adjustment for a desired payload size, payload configuration modification, and / or payload reduction). Deployments can include devices with reduced capabilities and / or reduced transmission capabilities compared to other communication devices. Background Art

[0004] In a wireless communication system, e.g., those specified in the standards for 5G New Radio (NR), a base station and a user equipment (UE) can utilize beamforming to compensate for high path loss and short distances. Beamforming is a signal - processing technique for an antenna array for directional signal transmission and / or reception. Antennas in the antenna array can transmit signals that are combined with other signals of other antennas in the same array, such that signals at a specific angle encounter constructive interference while other antennas encounter destructive interference. The collective effect of the interference may change the signal shape for transmission and / or reception purposes.

[0005] To select one or more beams for communication between a base station and a UE, the base station can transmit reference signals on multiple beams via beam scanning, e.g., a synchronization signal block (SSB) or a channel state information (CSI) reference signal (CSI - RS). The UE can send information in response to the reference signals to assist the BS in channel estimation for subsequent signaling or transmission. Summary of the Invention

[0006] An overview of one or more aspects of the present disclosure is presented below to provide a basic understanding of these aspects. This summary is not an extensive overview of all the expected features of the present disclosure, and is neither intended to identify the key or important elements of all aspects of the present disclosure nor to describe the scope of any or all aspects of the present disclosure. Its sole purpose is to present some concepts of one or more aspects of the present disclosure in a form that serves as a prelude to the more detailed description that follows.

[0007] Aspects of the present disclosure relate to the configuration of measurement reports (e.g., layer 1 (L1) measurement reports). A radio access network (RAN) node (e.g., a base station) may send at least one reporting setting to a wireless communication device (e.g., a UE), each reporting setting being associated with a selected information type. The selected information type may be selected from a first information type and a second information type. When the reporting setting is associated with the first information type, the wireless communication device may send an L1 measurement report that includes beam measurements corresponding to the beam measurements for the reporting setting and beam identifiers. When the reporting setting is associated with the second information type, the wireless communication device may exclude the beam identifiers from the L1 measurement report that includes the beam measurements for the reporting setting. Thus, the L1 measurement report that includes the beam measurements for the second information type has a reduced payload compared to the L1 measurement report that includes the beam measurements for the first information type.

In response to the selected information type for the first reporting setting including the second information type, the L1 measurement report can also exclude the respective beam identifiers corresponding to each first beam measurement.

[0024] Examples of various methods, systems, devices, and apparatuses can also include other features. For example, the wireless communication device can also be configured to obtain second beam measurement information including second beam measurements based on a second reporting setting of the at least one reporting setting. Each second beam measurement can correspond to one of a second set of multiple beams. The wireless communication device can also be configured to include the second beam measurement information in the L1 measurement report.

[0025] In some examples, in response to a selected information type for a first report being set to a first information type, the L1 measurement report may include first beam measurement information and corresponding beam identifiers corresponding to each of the first beam measurements. In some examples, in response to a selected information type for a second report being set to a second information type, the L1 measurement report may further include second beam measurement information and exclude the corresponding beam identifiers corresponding to each of the second beam measurements. In some examples, in response to the selected information type for the first report setting including the second information type, the L1 measurement report may include first beam measurement information and exclude the corresponding beam identifiers corresponding to each of the first beam measurements. Additionally, in response to the selected information type for the second report setting including the first information type, the L1 measurement report may further include second beam measurement information and corresponding beam identifiers corresponding to each of the second beam measurements. In some examples, in response to the selected information type for each of the first report setting and the second report setting being the same, the L1 measurement report includes first beam measurement information and second beam measurement information.

[0026] In some examples, in response to the respective selected information types for each of the first report setting and the second report setting being different, the L1 measurement report may further include corresponding type indicators for the selected information types for each of the first report setting and the second report setting.

In some examples, the RAN node may also be configured to blindly detect the selected information type of the L1 measurement report.

[0027] In some examples, the L1 measurement report is a periodic L1 measurement report or a semi-persistent L1 measurement report. In some examples, the first beam measurements in the first beam measurement information are arranged in a first order of the corresponding beam identifiers. In response to the selected information type associated with the L1 measurement report being the second information type, the first order may include the same order as a previous L1 measurement report or a previous report setting of a previous L1 measurement report. In some examples, the absolute beam measurement includes an exact value of the highest beam measurement for the first beam measurement and corresponding differential values relative to the exact values of each of the remaining beam measurements for the first beam measurement.

[0028] In some examples, the first beam measurement in the first beam measurement information includes: a differential beam measurement relative to a previous L1 measurement report or a previous reporting setting of a previous L1 measurement report. In some examples, the previous L1 measurement report includes: an additional differential beam measurement relative to another previous L1 measurement report or another previous reporting setting. In some examples, the previous L1 measurement report includes an absolute beam measurement.

[0029] In some examples, the L1 measurement report is aperiodic L1 measurement report. In some examples, the wireless communication device may also be configured to receive, from a RAN node, reporting information associated with a first reporting setting. In some examples, the reporting information may indicate a first permutation of the first beam measurements in the L1 measurement report in a specified order according to corresponding beam identifiers. In some examples, the reporting information may indicate a second permutation of the first beam measurements in the L1 measurement report in the same order as that of a previous L1 measurement report or a previous reporting setting of a previous L1 measurement report according to corresponding beam identifiers.

[0030] In some examples, the wireless communication device may also be configured to measure a reference signal on each beam in a first set of multiple beams to obtain first beam measurement information. The corresponding beam identifier for each respective beam in the first set of multiple beams may include a reference signal resource indicator associated with the reference signal and the respective beam. In some examples, the reference signal includes a synchronization signal block (SSB) or a channel state information (CSI) reference signal (CSI-RS). In some examples, the first beam measurement information includes a corresponding reference signal received power (RSRP) measurement for each beam in the first set of multiple beams, or a corresponding signal-to-interference-plus-noise (SINR) measurement for each beam in the first set of multiple beams.

[0051] The following detailed description, presented in conjunction with the accompanying drawings, is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein may be implemented. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0052] The electromagnetic spectrum is typically subdivided into various classes, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as the frequency range names FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is typically (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Regarding FR2, a similar naming issue sometimes arises, and it is typically (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0053] The frequency between FR1 and FR2 is generally referred to as the mid-band frequency. Recent 5G NR research has identified the operating bands of these mid-band frequencies as the frequency range name FR3 (7.125 GHz - 24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 to the mid-band frequency. In addition, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as the frequency range names FR4-a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0054] Considering the above aspects, unless otherwise specifically stated, it should be understood that if used herein, terms such as "sub-6GHz" can generally represent frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically specified, it should be understood that if used herein, terms such as "millimeter wave" can generally represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or can be within the EHF band.

[0055] It should be understood that the above examples are not necessarily intended to limit the claimed subject matter. For example, unless specifically recited, the claimed subject matter related to wireless communication is not necessarily intended to be limited to any specific frequency bands defined by any specific author / entity, etc.

[0056] While the present application describes aspects and examples by way of illustration of some examples, those skilled in the art will appreciate that additional embodiments and use cases can arise in many different arrangements and scenarios. The innovations described herein can be implemented on many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, aspects and / or uses can be implemented via integrated chip examples and other devices based on non-module components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / purchasing devices, medical devices, AI-enabled devices, etc.). While some examples may or may not be specifically targeted at use cases or applications, the innovations described can arise in a variety of applications. Embodiments can range from chip-level or modular components to non-modular, non-chip-level embodiments, to aggregated, distributed, or OEM devices or systems incorporating one or more aspects of the innovation. In some practical settings, devices incorporating the aspects and features may also necessarily include additional components and features for implementing and practicing the claimed and described examples. For example, the transmission and reception of wireless signals necessarily includes many components for analog and digital purposes (e.g., hardware components including antennas, RF chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). It is intended that the innovations described herein can be implemented in a wide variety of devices, chip-level components, systems, distributed arrangements, aggregated or de-aggregated scenarios, end-user devices, etc., of various different sizes, shapes, and configurations.

[0057] The various concepts presented in this disclosure can be implemented in a variety of telecommunication systems, network architectures, and communication standards. Now refer to Figure 1 , by way of illustrative example and not limitation, aspects of the present disclosure will be described with reference to wireless communication system 100. Wireless communication system 10 includes three interacting domains: core network 102, radio access network (RAN) 104, and user equipment (UE) 106. With the aid of wireless communication system 100, UE 106 can be permitted to perform data communication with an external data network 110 (such as, but not limited to, the Internet).

[0058] RAN 104 can implement any suitable wireless communication technology or technique to provide radio access to UE 106. By way of example, RAN 104 can operate in accordance with the New Radio (NR) specification of the 3rd Generation Partnership Project (3GPP) (commonly referred to as 5G). By way of another example, RAN 104 can operate in a hybrid of 5G NR and the evolved Universal Terrestrial Radio Access Network (eUTRAN) standard (commonly referred to as Long Term Evolution (LTE)). 3GPP refers to this hybrid RAN as the Next Generation RAN or NG-RAN. Of course, many other examples can be used within the scope of the present disclosure.

[0059] As shown in the figure, RAN 104 includes a plurality of base stations 108. Broadly speaking, a base station is a network element in a radio access network that is responsible for radio transmission or reception to or from a UE in one or more cells. In different technologies, standards, or contexts, those of ordinary skill in the art may also refer to a base station differently as a base transceiver station (BTS), radio base station, radio transceiver, transceiver function, basic service set (BSS), extended service set (ESS), access point (AP), Node B (NB), eNode B (eNB), gNode B, transmit or receive point (TRP), or some other suitable term. In some examples, a base station may include two or more TRPs that may be co-located or non-co-located. Each TRP may communicate on the same or different carrier frequencies within the same or different frequency bands. In an example where RAN 104 operates according to both LTE and 5G NR standards, one of these base stations may be an LTE base station, while another base station may be a 5G NR base station.

[0060] RAN 104 is further shown as supporting wireless communication for a plurality of mobile devices. In 3GPP standards, a mobile device may be referred to as a user equipment (UE), but those of ordinary skill in the art may also refer to it as a mobile station (MS), user station, mobile unit, user unit, radio unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile user station, access terminal (AT), mobile terminal, wireless terminal, remote terminal, handheld device, terminal, user agent, mobile client, client, or other suitable term. A UE may be a device (e.g., a mobile device) that provides a user with access to network services.

[0061] In the present disclosure, a “mobile” device does not necessarily have the ability to move and may be stationary. The terms mobile device or mobile equipment broadly refer to various devices and technologies. A UE may include a plurality of hardware structural components of various sizes, shapes, and arranged to facilitate communication; these components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc., that are electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile devices, cellular (cell) phones, smartphones, session initiation protocol (SIP) phones, laptop computers, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, personal digital assistants (PDAs), and various embedded systems, e.g., corresponding to the “Internet of Things” (IoT).

[0062] The mobile device can also be an automobile or other transportation vehicle, a remote sensor or actuator, a robot or robotic device, a satellite radio device, a Global Positioning System (GPS) device, an object tracking device, a drone, a multi-copter, a quadcopter, a remote control device, a consumer and / or wearable device, such as glasses, a wearable camera, a virtual reality device, a smart watch, a health or fitness tracker, a digital audio player (e.g., an MP3 player), a camera, a gaming console, etc. The mobile device can also be a digital home or smart home device, such as, for example, a home audio, video, and / or multimedia device, a household appliance, a vending machine, smart lighting, a home security system, a smart meter, etc. The mobile device can also be a smart energy device, a security device, a solar panel or solar array, a municipal infrastructure device that controls power (e.g., a smart grid), lighting, water supply, etc., an industrial automation and enterprise device, a logistics controller, and / or an agricultural device, etc. Additionally, the mobile device can provide connected medical or telemedicine support, such as, for example, telehealth. The telehealth device can include a telehealth monitoring device and a telehealth management device, and its communication can be processed or accessed preferentially (e.g., in terms of priority access for the transmission of critical service data and / or relevant QoS for the transmission of critical service data) over other types of information.

[0063] The fifth generation (5G) wireless communication network, such as the New Radio (NR) wireless communication network, supports communication between the base station 108 and the high-end UE 106 for a variety of different use cases, including, for example, enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (URLLC). In the massive machine type communication (mMTC) use case, the NR network can also support communication between the base station and the low-end UE 106. In some examples, LTE-M or NarrowBand Internet of Things (NB-IoT) technology can be used to meet the requirements of mMTC.

[0064] In addition to serving high-end UEs 106 (e.g., via eMMB and / or URLLC) and low-end UEs 106 (e.g., via mMTC), the NR network can also serve reduced-capability UEs 106. The service requirements for reduced-capability UEs can be less than those of high-end UEs but greater than those of low-end UEs. For example, use cases for reduced-capability UEs can include not only URLLC services with high requirements but also low-end services for accommodating smaller form factors and longer battery life. Examples of reduced-capability UEs can include, but are not limited to, industrial wireless sensors, surveillance cameras, and wearable devices (e.g., smartwatches, rings, electronic health-related devices, and medical monitoring devices). Generally speaking, compared with high-end UEs, reduced-capability UEs have a compact form factor and a device design with reduced complexity. For example, a reduced-capability UE can have a reduced number of transmit / receive antennas, a reduced device bandwidth (e.g., a reduced operating bandwidth of the UE), a relaxed processing time, and / or a relaxed processing capacity. In latency-tolerant use cases, a reduced-capability UE can also be configured for power saving and enhanced battery life.

[0065] The specific services provided to a UE (e.g., eMBB / URLLC / mMTC / reduced-capability) can be determined based on the UE's UE category. UE category information is used to enable the base station to communicate effectively with each UE served by the base station. For example, the UE category can identify the uplink and downlink performance capabilities of the UE. For example, the UE category can specify the maximum data rate supported by the UE, the number of component carriers and multiple-input multiple-output (MIMO) layers supported by the UE, and / or the highest modulation supported by the UE. The examples of UE category discriminators shown herein are merely exemplary, and it should be understood that any appropriate distinction between UE characteristics, whether hardware or software, can be used to distinguish UE categories.

[0066] The wireless communication between the RAN 104 and the UE 106 can be described as employing an air interface. Transmissions from a base station (e.g., base station 108) to one or more UEs (e.g., similar to UE 106) via the air interface can be referred to as downlink (DL) transmissions. According to certain aspects of the present disclosure, the term downlink can refer to a point-to-multipoint transmission originating from a base station (e.g., base station 108). Another way to describe this scheme is to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. According to further aspects of the present disclosure, the term uplink can refer to a point-to-point transmission originating at a UE (e.g., UE 106).

[0067] In some examples, access to an air interface can be scheduled, where a scheduling entity (e.g., base station 108) allocates resources for communication between some or all of the devices and apparatuses within its serving area or cell. In the present disclosure, as further discussed below, the scheduling entity can be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more scheduled entities (e.g., UE 106). That is, for scheduled communication, multiple UEs 106 (which can be the scheduled entities) can utilize the resources allocated by the scheduling entity 108.

[0068] Base station 108 is not the only entity that can be used as a scheduling entity. That is, in some examples, a UE can be used as a scheduling entity to schedule resources for one or more scheduled entities (e.g., one or more other UEs). For example, a UE can communicate directly with other UEs in a peer-to-peer or device-to-device manner and / or in a relay configuration.

[0069] As Figure 1 shown, the scheduling entity 108 can broadcast downlink traffic 112 to one or more scheduled entities (e.g., one or more UEs 106). Broadly speaking, the scheduling entity 108 is a node or device responsible for scheduling traffic (including downlink traffic 112) in a wireless communication network and, in some examples, uplink traffic 116 from one or more scheduled entities (e.g., one or more UEs 106) to the scheduling entity 108. On the other hand, a scheduled entity (e.g., UE 106) is a node or device that receives downlink control information 114 from another entity (e.g., the scheduling entity 108) in the wireless communication network, including but not limited to scheduling information (e.g., grants), synchronization or timing information, or other control information.

[0070] In addition, uplink and / or downlink control information and / or traffic information can be transmitted on a waveform that can be divided in time into frames, subframes, time slots, and / or symbols. As used herein, a symbol can refer to a time unit in an orthogonal frequency division multiplexing (OFDM) waveform where each subcarrier carries one resource element (RE). A time slot can carry 7 or 14 OFDM symbols. A subframe can refer to a duration of 1 ms. Multiple subframes or time slots can be combined together to form a single frame or radio frame. Within the present disclosure, a frame can refer to a predetermined duration for wireless transmission (e.g., 10 ms), where each frame includes, for example, 10 subframes, where each subframe is 1 ms. Of course, these definitions are not required, and any suitable scheme for organizing the waveform can be used, and the various time divisions of the waveform can have any suitable duration.

[0071] Typically, base station 108 may include a backhaul interface for communicating with the backhaul portion 120 of the wireless communication system 100. The backhaul portion 120 may provide a link between the base station 108 and the core network 102. Additionally, in some examples, the backhaul network may provide an interconnection between the respective base stations 108. Various types of backhaul interfaces may be used, such as, for example, direct physical connections, virtual networks, or analogs using any suitable transport network, etc.

[0072] The core network 102 may be part of the wireless communication system 100 and may be independent of the radio access technology used in the RAN 104. In some examples, the core network 102 may be configured according to 5G standards (e.g., 5GC). In other examples, the core network 102 may be configured according to 4G evolved packet core (EPC) or any other suitable standard or configuration.

[0073] Now referring to Figure 2 , by way of illustrative example and not limitation, a schematic diagram of a radio access network (RAN) 200 in accordance with some aspects of the present disclosure is provided. In some examples, the RAN 200 may be the same as the RAN 104 described above and as shown in Figure 1 .

[0074] The geographical area covered by the RAN 200 may be divided into a plurality of cellular regions (cells), which may be uniquely identified by user equipment (UE) based on an identification broadcast over the geographical area from an access point or base station. Figure 2 Cells 202, 204, 206, and 208 are shown, and each cell may include one or more sectors (not shown). A sector is a sub-region of a cell. All sectors within a cell are served by the same base station. The radio link within a sector may be identified by a single logical identification belonging to that sector. In a cell divided into multiple sectors, the multiple sectors within a cell may be formed by a group of antennas, and each antenna is responsible for communicating with UEs in a part of the cell.

[0075] Various base station arrangements may be utilized. For example, in Figure 2In it, two base stations are shown in cells 202 and 204: base station 210 and base station 212. A third base station, base station 214, is shown as controlling a remote radio head (RRH) 216 in cell 206. That is to say, a base station can have an integrated antenna or can be connected to an antenna or RRH 216 via a feeder cable. In the example shown, cells 202, 204, and 206 can be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. In addition, base station 218 is shown located in cell 208 which can overlap with one or more macro cells. In this example, cell 208 can be referred to as a small cell (e.g., micro cell, pico cell, femto cell, home base station, home node B, home eNode B, etc.) because base station 218 supports a cell with a relatively small size. Cell size adjustment can be implemented according to system design and component constraints.

[0076] It should be understood that RAN 200 can include any number of radio base stations and cells. In addition, relay nodes can be deployed to expand the size or coverage area of a given cell. Base stations 210, 212, 214, 218 provide a wireless access point to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 can be the same as or similar to the scheduling entity 108 described above and shown in Figure 1 as shown.

[0077] Figure 2 It also includes an unmanned aerial vehicle (UAV) 220, which can be a drone or a quadcopter. UAV 220 can be configured to be used as a base station, or more specifically, as a mobile base station. That is to say, in some examples, a cell may not necessarily be stationary, and the geographical area of the cell can move according to the position of a mobile base station (such as UAV 220).

[0078] Within RAN 200, a cell can include UEs that can communicate with one or more sectors of each cell. In addition, each of base stations 210, 212, 214, 218, and 220 can be configured to provide an access point to the core network 102 (see Figure 1 ) for all UEs in the respective cells. For example, UEs 222 and 224 can communicate with base station 210; UEs 226 and 228 can communicate with base station 212; UEs 230 and 232 can communicate with base station 214 via RRH 216; UE 234 can communicate with base station 218; and UE 236 can communicate with mobile base station 220. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240, and / or 242 can be the same as those described above and shown in Figure 1is the same as or similar to the UE / scheduled entity 106 shown. In some examples, the UAV 220 (e.g., quadcopter) can be a mobile network node and can be configured to act as a UE. For example, the UAV 220 can operate within the cell 202 by communicating with the base station 210.

[0079] In another aspect of the RAN 200, sidelink signals can be used between UEs without relying on scheduling or control information from the base station. For example, sidelink communication can be used in device-to-device (D2D) networks, peer-to-peer (P2P) networks, vehicle-to-vehicle (V2V) networks, vehicle-to-everything (V2X) networks, and / or other suitable sidelink networks. For example, two or more UEs (e.g., UEs 238, 240, and 242) can communicate with each other using the sidelink signal 237 without relaying the communication through the base station. In some examples, UEs 238, 240, and 242 can each act as a scheduling entity or a transmitting sidelink device and / or a scheduling entity or a receiving sidelink device to schedule resources and transmit the sidelink signal 237 therebetween without relying on scheduling or control information from the base station. In other examples, two or more UEs (e.g., UEs 226 and 228) within the coverage area of a base station (e.g., base station 212) can also transmit the sidelink signal 227 through a direct link (sidelink) without transmitting the communication through the base station 212. In this example, the base station 212 can allocate resources for UEs 226 and 228 to perform sidelink communication.

[0080] To achieve a low block error rate (BLER) on the air interface while still achieving extremely high data rates, channel coding can be used. That is, wireless communication can generally use suitable error-correcting block codes. In a typical block code, an information message or sequence is divided into code blocks (CBs), and then an encoder (e.g., CODEC) at the transmitting device mathematically adds redundancy to the information message. Using this redundancy in the encoded information message can improve the reliability of the message, thus enabling the correction of any bit errors that may occur due to noise.

[0081] Data coding can be achieved in various ways. In the early 5G NR specifications, user data was encoded using quasi-cyclic low-density parity-check (LDPC) and two different base graphs: one base graph for large code blocks and / or high code rates, and the other base graph for other cases. Control information and the physical broadcast channel (PBCH) were encoded using polar codes based on nested sequences. For these channels, puncturing, shortening, and repetition were used for rate matching.

[0082] Aspects of the present disclosure may be implemented using any suitable channel code. Various implementations of the base station and the UE may include suitable hardware and functionality (e.g., an encoder, a decoder, and / or a CODEC) to use one or more of these channel codes for wireless communication.

[0083] In the RAN 200, the ability of the UE to communicate while moving, independent of its location, is referred to as mobility. The various physical channels between the UE and the RAN are typically established, maintained, and released under the control of an access and mobility management function (AMF, not shown, which is Figure 1 part of the core network 102 in ). In some cases, the AMF may include a security context management function (SCMF) that performs authentication and a security anchor function (SEAF). The SCMF may manage the security context for both the control plane and the user plane functions, either in whole or in part.

[0084] In some examples, the RAN 200 may implement mobility and handover (i.e., switching the connection of the UE from one radio channel to another). For example, during a call with a scheduling entity or at any other time, the UE may monitor various parameters of the signal from its serving cell as well as various parameters of neighboring cells. Based on the quality of these parameters, the UE may maintain communication with one or more neighbor cells. During this period, if the UE moves from one cell to another, or if the signal quality from a neighboring cell exceeds the signal quality from the serving cell within a given time, the UE may perform a handover or transition from the serving cell to the neighboring (target) cell. For example, the UE 224 (illustrated as a vehicle, although any suitable form of UE may be used) may move from the geographical area corresponding to its serving cell 202 to the geographical area corresponding to the neighbor cell 206. When the signal strength or quality from the neighboring cell 206 exceeds the signal strength and quality of its serving cell 202 within a given time, the UE 224 may send a report message indicating this condition to its serving base station 210. In response, the UE 224 may receive a handover command, and the UE may undergo a handover to the cell 206.

[0085] In various embodiments, the air interface in radio access network 200 may use licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum provides exclusive use of a portion of the spectrum, typically achieved by a mobile network operator purchasing a license from a government regulatory agency. Unlicensed spectrum allows for shared use of a portion of the spectrum without government permission. Although some technical rules may still generally need to be adhered to for access to unlicensed spectrum, typically any operator or device may obtain access. Shared spectrum may fall between licensed and unlicensed spectrum, where access to the spectrum may require technical rules or restrictions, but the spectrum may still be shared by multiple operators and / or multiple RATs. For example, the holder of a license for a portion of licensed spectrum may provide licensed shared access (LSA) to share the spectrum with other parties, e.g., with appropriate licensee determined conditions for obtaining access.

[0086] Devices communicating in radio access network 200 may use one or more multiplexing techniques and multiple access algorithms to enable simultaneous communication of various devices. For example, the 5G NR specification provides multiple access for UL or transmission from UEs 222 and 224 to base station 210, and multiplexes DL transmissions from base station 210 to one or more UEs 222 or 224 using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP). Additionally, for UL transmissions, the 5G NR specification provides support for discrete Fourier transform spread OFDM (DFT-s-OFDM) with CP (also known as single carrier FDMA (SC-FDMA)). However, within the scope of the present disclosure, multiplexing and multiple access are not limited to the above schemes, and time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), sparse code multiple access (SCMA), resource spreading multiple access (RSMA), or other suitable multiple access schemes may be utilized to provide. Additionally, time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM), or other suitable multiplexing schemes may be utilized to provide multiplexing of DL transmissions from base station 210 to UEs 222 and UE 224.

[0087] Devices in the radio access network 200 may also use one or more duplexing algorithms. Duplexing refers to a point-to-point communication link where two endpoints can communicate with each other in two directions. Full duplex means that the two endpoints can communicate with each other simultaneously. Half duplex means that only one endpoint can send information to the other endpoint at a time. Half-duplex emulation is typically used for wireless links that use time-division duplexing (TDD). In TDD, time-division multiplexing is used to separate transmissions in different directions on a given channel from each other. That is, in some cases, the channel is dedicated to transmissions in one direction, while at other times, the channel is dedicated to transmissions in the other direction, where the direction may change very quickly, for example, several times per time slot. In a wireless link, a full-duplex channel typically relies on physical isolation of the transmitter and receiver, as well as appropriate interference cancellation techniques. Full-duplex emulation is typically achieved for a wireless link by using frequency-division duplexing (FDD) or space-division duplexing (SDD). In FDD, transmissions in different directions can operate at different carrier frequencies (e.g., within a paired spectrum). In SDD, space-division multiplexing (SDM) is used to separate transmissions in different directions on a given channel from each other. In other examples, full-duplex communication can be achieved within an unpaired spectrum (e.g., within a single-carrier bandwidth), where transmissions in different directions occur in different sub-bands of the carrier bandwidth. This type of full-duplex communication may be referred to herein as sub-band full-duplex (SBFD), and is also known as flexible duplexing.

[0088] Reference will be made to Figure 3 the OFDM waveform schematically shown in

[0089] Now reference is made to Figure 3 , which shows an expanded view of an exemplary subframe 302 that displays an OFDM resource grid. However, as will be readily understood by those skilled in the art, the PHY transmission structure for any particular application may differ from the examples described herein depending on any number of factors. Here, time is in the horizontal direction, in units of OFDM symbols; and frequency is in the vertical direction, in units of subcarriers of the carrier.

[0090] The resource grid 304 can be used to schematically represent time-frequency resources for a given antenna port. That is, in a multiple-input multiple-output (MIMO) implementation with multiple available antenna ports, the corresponding multiple resource grids 304 can be available for communication. The resource grid 304 is divided into multiple resource elements (REs) 306. An RE (which is 1 carrier × 1 symbol) is the smallest discrete part of the time-frequency grid and contains a single complex value representing data from a physical channel or signal. Depending on the modulation used in a particular implementation, each RE can represent one or more bits of information. In some examples, a block of REs can be referred to as a physical resource block (PRB) or more simply as a resource block (RB) 308, which contains any appropriate number of contiguous subcarriers in the frequency domain. In one example, an RB can include 12 subcarriers, regardless of the numerology used. In some examples, depending on the numerology, an RB can include any appropriate number of contiguous OFDM symbols in the time domain. Within this disclosure, it is assumed that a single RB (e.g., RB 308) fully corresponds to a single communication direction (either the transmit or receive direction for a given device).

[0091] A set of contiguous or non-contiguous resource blocks can be referred to herein as a resource block group (RBG), subband, or bandwidth part (BWP). A set of subbands or BWPs can span the entire bandwidth. Scheduling of a scheduled entity (e.g., a UE) for downlink, uplink, or sidelink transmission typically involves scheduling one or more resource elements 306 within one or more subbands or bandwidth parts (BWPs). Thus, a UE typically uses only a subset of the resource grid 304. In some examples, an RB can be the smallest resource unit that can be allocated to a UE. Thus, the more RBs scheduled for a UE and the higher the modulation scheme selected for the air interface, the higher the data rate for the UE. RBs can be scheduled by a scheduling entity (such as a base station (e.g., gNB, eNB, etc.)) or can be self-scheduled by a UE implementing D2D sidelink communication.

[0092] In this illustration, RB 308 is shown as occupying less than the entire bandwidth of subframe 302, with some subcarriers shown above and below RB 308. In a given implementation, subframe 302 can have a bandwidth corresponding to any number of one or more RBs 308. Additionally, in this illustration, although RB 308 is shown as occupying less than the entire duration of subframe 302, this is only one possible example.

[0093] Various deployments can utilize various subframe and / or slot configurations. In some cases, subframes can have a fixed size or duration. In some examples, each subframe can be a 1 ms subframe 302. Subframe 302 can be composed of one or more adjacent time slots. In Figure 3 the example shown, one subframe 302 includes four time slots 310, as an illustrative example. In some examples, a time slot can be defined according to a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, a time slot can include 7 or 14 OFDM symbols with a nominal CP. Additional examples can include mini-slots (sometimes referred to as shortened transmission time intervals (TTIs)) with a shorter duration (e.g., one or three OFDM symbols). In some cases, these mini-slots or shortened TTIs can be transmitted by occupying resources scheduled for ongoing time slot transmissions for the same or different UEs. Any number of resource blocks can be employed within a subframe or a time slot.

[0094] An expanded view of one of the time slots 310 shows that the time slot 310 includes a control region 312 and a data region 314. Generally, the control region 312 can carry control channels, and the data region 314 can carry data channels. Of course, a time slot can contain all DL, all UL, or at least one DL part and at least one UL part. Figure 3 The structure shown in

[0095] is merely exemplary in nature, and different time slot structures can be utilized, and different time slot structures can include one or more regions in each of the control region and the data region. Figure 3 Although not shown in

[0096] each individual RE 306 within the RB 308 can be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc. Other RE 306 within the RB 308 can also carry pilots or reference signals. These pilots or reference signals can enable a receiving device to perform channel estimation for the corresponding channels, which can enable coherent demodulation / detection of the control and / or data channels within the RB 308.

[0097] In an example of cellular communication via a cellular carrier over the Uu interface, for DL transmission, a scheduling entity (e.g., a base station) may allocate one or more REs 306 (e.g., within the control region 312) to carry DL control information including one or more DL control channels (e.g., Physical Downlink Control Channel (PDCCH)) destined for one or more scheduled entities (e.g., UEs). The PDCCH carries Downlink Control Information (DCI), which includes but is not limited to power control commands (e.g., one or more open-loop power control parameters and / or one or more closed-loop power control parameters), scheduling information, grants, and / or assignments of REs for DL and UL transmissions. The PDCCH may also carry HARQ feedback transmissions, such as an acknowledgement (ACK) or a negative acknowledgement (NACK). HARQ is a technique well known to those skilled in the art, where the integrity of a packet transmission can be verified for accuracy at the receiving side, e.g., using any suitable integrity verification mechanism, such as a checksum or a Cyclic Redundancy Check (CRC). If the integrity of the transmission is confirmed, an ACK may be sent, while if the integrity of the transmission is not confirmed, a NACK may be sent. In response to a NACK, the transmitting device may send a HARQ retransmission, which may implement chase combining, incremental redundancy, etc.

[0098] The base station may further allocate one or more REs 306 (e.g., in the control region 312 or the data region 314) to carry other DL signals, such as Demodulation Reference Signals (DMRS); Phase Tracking Reference Signals (PT-RS); Channel State Information (CSI) Reference Signals (CSI-RS); and Synchronization Signal Blocks (SSB). The SSB may be broadcast periodically based on a period (e.g., 5, 10, 20, 30, 80, or 130 ms). The SSB includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Control Channel (PBCH). The UE may utilize the PSS and SSS to achieve radio frame, subframe, slot, and symbol synchronization in the time domain, identify the center of the channel (system) bandwidth in the frequency domain, and identify the Physical Cell Identity (PCI) of the cell.

[0099] The PBCH in SSB may also include a Master Information Block (MIB), which includes various system information and parameters for decoding System Information Blocks (SIBs). For example, the SIB may be System Information Type 1 (SIB1), which may include various additional system information. The MIB and SIB1 together provide the minimum system information (SI) for initial access. Examples of the system information transmitted in the MIB may include, but are not limited to, subcarrier spacing (e.g., default downlink numerology), system frame number, configuration of the PDCCH control resource set (CORESET) (e.g., PDCCH CORESET0), cell bar indicator, cell reselection indicator, grid offset, and search space for SIB1. Examples of the remaining minimum system information (RMSI) transmitted in SIB1 may include, but are not limited to, random access search space, paging search space, downlink configuration information, and uplink configuration data. The base station may also transmit other system information (OSI).

[0100] In UL transmission, the scheduled entity (e.g., UE) may utilize one or more REs 306 to carry UL control information (UCI), which includes one or more UL control channels (e.g., Physical Uplink Control Channel (PUCCH)) to the scheduling entity. The UCI may include a variety of packet types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmissions. Examples of uplink reference signals may include Sounding Reference Signals (SRS) and uplink DMRS. In some examples, the UCI may include a Scheduling Request (SR), i.e., a request for the scheduling entity to schedule an uplink transmission. Here, in response to the SR sent on the UCI, the scheduling entity may send Downlink Control Information (DCI), which may schedule resources for uplink packet transmission. The UCI may also include HARQ feedback, Channel State Feedback (CSF) (such as CSI report), or any other appropriate UCI.

[0101] In addition to control information, one or more REs 306 (e.g., within the data region 314) may also be allocated for data traffic. Such data traffic may be carried on one or more traffic channels (e.g., for DL transmission, Physical Downlink Shared Channel (PDSCH); or for UL transmission, Physical Uplink Shared Channel (PUSCH)). In some examples, one or more REs 306 within the data region 314 may be configured to carry other signals, such as one or more SIBs and DMRS.

[0102] In an example of sidelink communication via a sidelink carrier over a Proximity Services (ProSe) PC5 interface, the control region 312 of slot 310 may include a Physical Sidelink Control Channel (PSCCH) that includes sidelink control information (SCI) transmitted by an initiating (transmitting) sidelink device (e.g., a Tx V2X device or other Tx UE) to a group of one or more other receiving sidelink devices (e.g., an Rx V2X device or other Rx UE). The data region 314 of slot 310 may include a Physical Sidelink Shared Channel (PSSCH) that includes sidelink data traffic transmitted by the initiating (transmitting) sidelink device within resources reserved on the sidelink carrier via the SCI. Other information may also be transmitted via various resource elements 306 within slot 310. For example, HARQ feedback information may be transmitted from a receiving sidelink device to a transmitting sidelink device in a Physical Sidelink Feedback Channel (PSFCH) within slot 310. Additionally, one or more reference signals may be transmitted within slot 310, such as a sidelink SSB, a sidelink CSI-RS, a sidelink SRS, and / or a sidelink positioning reference signal (PRS).

[0103] These physical channels described above are typically multiplexed and mapped to transport channels for processing at the Medium Access Control (MAC) layer. A transport channel carries a block of information referred to as a transport block (TB). The transport block size (TBS), which may correspond to the number of information bits, may be a controlled parameter based on the modulation and coding scheme (MCS) and the number of resource blocks (RBs) in a given transmission.

[0104] Figure 3 The channels or carriers shown are not necessarily all the channels or carriers that can be used between devices, and one of ordinary skill in the art will recognize that other channels or carriers (such as other traffic, control, and feedback channels) may be used in addition to those shown.

[0105] In some aspects of the present disclosure, a scheduling entity and / or a scheduled entity may be configured for beamforming and / or multiple-input multiple-output (MIMO) techniques. Figure 4 An example of a wireless communication system 400 that supports beamforming and / or MIMO is shown. In a MIMO system, a transmitter 402 includes a plurality of transmit antennas 404 (e.g., N transmit antennas), and a receiver 406 includes a plurality of receive antennas 408 (e.g., M receive antennas). Thus, there are N×M signal paths 410 from the transmit antennas 404 to the receive antennas 408. Each of the transmitter 402 and the receiver 406 may be implemented, for example, in a scheduling entity, a scheduled entity, or any other suitable wireless communication device.

[0106] The use of this multi-antenna technology enables a wireless communication system to utilize the spatial domain to support spatial multiplexing, beamforming, and transmit diversity. Spatial multiplexing can be used to simultaneously transmit different data streams (also referred to as layers) on the same time-frequency resources. The data streams can be sent to a single UE to increase the data rate, or to multiple UEs to increase the overall system capacity, the latter being referred to as multi-user MIMO (MU-MIMO). This is achieved by spatially pre-coding each data stream (i.e., multiplying the data stream by different weights and phase shifts) and then transmitting each spatially pre-coded stream on the downlink via multiple transmit antennas. The spatially pre-coded data streams arrive at the UEs with different spatial signatures, which enables each UE among the UEs to recover one or more data streams destined for that UE. On the uplink, each UE transmits a spatially pre-coded data stream, which enables the base station to identify the source of each spatially pre-coded data stream.

[0107] The number of data streams or layers corresponds to the transmission rank. Generally, the rank of the MIMO system 400 is limited by the number of transmit antennas 404 or receive antennas 408 (whichever is lower). Additionally, the channel conditions at the UE and other considerations (such as the available resources at the base station) may also affect the transmission rank. For example, the rank (and thus, the number of data streams) assigned to a particular UE on the downlink can be determined based on a rank indicator (RI) sent from the UE to the base station. The RI can be determined based on the antenna configuration (e.g., the number of transmit and receive antennas) and the signal-to-interference-plus-noise ratio (SINR) measured on each of the receive antennas. The RI can indicate, for example, the number of layers that can be supported under the current channel conditions. The base station can use the RI and resource information (such as the available resources and the amount of data to be scheduled for the UE) to assign a transmission rank to the UE.

[0108] In one example, as Figure 4 shown, a rank-2 spatial multiplexing transmission on a 2x2 MIMO antenna configuration will send one data stream from each transmit antenna 404. Each data stream arrives at each receive antenna 408 along a different signal path 410. Then, the receiver 406 can use the signals received from each receive antenna 408 to reconstruct the data stream.

[0109] Beamforming is a signal processing technique that can be used at a transmitter 402 or a receiver 406 to form or direct an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitter 402 and the receiver 406. Beamforming can be achieved by combining signals transmitted via antennas 404 or 408 (e.g., antenna elements of an antenna array module) such that some signals experience constructive interference while other signals experience destructive interference. To create the desired constructive / destructive interference, the transmitter 402 or the receiver 406 can apply an amplitude and / or phase offset to the signals transmitted or received from each antenna 404 or 408 associated with the transmitter 402 or the receiver 406.

[0110] A base station (e.g., a gNB) can generally communicate with a UE using beams of different beamwidths. For example, the base station can be configured to use a wider beam when communicating with a moving UE and a narrower beam when communicating with a stationary UE. In some examples, to select a specific beam for communicating with a UE, the base station can transmit a reference signal, e.g., an SSB or a CSI-RS, on each of multiple beams in a beam scanning manner. In some examples, the SSB can be transmitted on a wider beam, while the CSI-RS can be transmitted on a narrower beam. The UE can measure the reference signal received power (RSRP) or the signal-to-interference-plus-noise ratio (SINR) on each beam and send a beam measurement report (e.g., a layer 1 (L1) measurement report) indicating the RSRP or SINR of one or more measured beams to the base station. Then, the base station can select a specific beam for communicating with the UE based on the L1 measurement report. In other examples, when the channel is reciprocal, the base station can derive a specific beam for communicating with the UE based on uplink measurements of one or more uplink reference signals, such as sounding reference signals (SRS).

[0111] In a 5G New Radio (NR) system, especially for systems above 6 GHz or millimeter wave systems, beamforming signals can be used for most downlink channels, including the Physical Downlink Control Channel (PDCCH) and the Physical Downlink Shared Channel (PDSCH). Additionally, broadcast control information, such as SSB, Slot Format Indicator (SFI), and paging information, can be transmitted in a beam scanning manner so that all scheduled entities (UEs) in the coverage area of a Transmission and Reception Point (TRP) (e.g., gNB) can receive the broadcast control information. Moreover, for UEs configured with beamforming antenna arrays, beamforming signals can also be used for uplink channels, including the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH). However, it should be understood that beamforming signals can also be used for enhanced mobile broadband (eMBB) gNBs in sub-6 GHz systems.

[0112] Figure 5 FIG. is a diagram showing communication using downlink beamforming signals between a Radio Access Network (RAN) node 504 and a wireless communication device 502, in accordance with some aspects of the present disclosure. The RAN node 504 can be Figure 1 and Figure 2 any base station or scheduling entity as shown in Figure 1 and Figure 2 and the wireless communication device 502 can be any one of the UEs or scheduled entities as shown in

[0113] In Figure 5In the example shown, the beam set includes eight different beams 521, 522, 523, 524, 525, 526, 527, 528, and each beam is associated with a different beam direction. In some examples, the RAN node 504 may be configured to scan or transmit each of the beams 521, 522, 523, 524, 525, 526, 527, 528 during the synchronization time slot. For example, the RAN node 504 may transmit a reference signal, such as an SSB or CSI-RS, on each beam in different beam directions during the synchronization time slot. The transmission of the beam reference signal may be periodic (e.g., as configured by the gNB via radio resource control (RRC) signaling), semi-persistent (e.g., configured via RRC signaling and activated / deactivated by the gNB via media access control-control element (MAC-CE) signaling), or aperiodic (e.g., triggered by the gNB via downlink control information (DCI)).

[0114] The wireless communication device 502 searches and identifies the beam based on the beam reference signal. Then, the wireless communication device 502 performs beam measurements (e.g., RSRP, SINR, RSRQ, etc.) on the beam reference signal to determine the corresponding beam quality of each beam. In an example where the wireless communication device 502 is in the RRC connected state, the wireless communication device 502 may generate an L1 measurement report and send it to the RAN node 504. The L1 measurement report includes the corresponding beam identifier (beam index) and beam measurements of one or more of the beams 521 - 528. Then, the RAN node 504 may determine a downlink beam (e.g., beam 524) on which to send unicast downlink control information and / or user data traffic to the wireless communication device 502. In some examples, the selected downlink beam has the highest gain from the L1 measurement report. The transmission of the L1 measurement report may be periodic (e.g., as configured by the gNB via RRC signaling), semi-persistent (e.g., configured by the gNB via RRC signaling and activated / deactivated via MAC-CE signaling), or aperiodic (e.g., triggered by the gNB via DCI).

[0115] In other examples, when the channel is reciprocal (e.g., the downlink and uplink channel qualities are the same), the RAN node 504 may derive the downlink beam. The derivation of the downlink beam may be based on uplink measurements performed by the RAN node 504, such as by measuring the received power, quality, or other variables of the sounding reference signal (SRS), or other uplink reference signals transmitted by the wireless communication device 502. In some examples, the RAN node 504 may derive the downlink beam based on a combination of the L1 measurement report and uplink measurements.

[0116] In an example where the wireless communication device 502 is in the RRC idle state, the wireless communication device 50 can use beam measurements to select a downlink beam on which to receive broadcast communication from the RAN node 504. The broadcast communication can include, for example, a paging message sent from the RAN node 504 to the wireless communication device 502 when new data arrives at the network for the wireless communication device 502. In some examples, the RAN node 504 can broadcast the paging message via multiple downlink beams. The wireless communication device 502 can then receive the paging message on the selected downlink beam.

[0117] In addition to the L1 measurement report, the wireless communication device 502 can further utilize beam reference signals to estimate the channel quality of the channel between the RAN node 504 and the wireless communication device 5012. For example, the wireless communication device can measure the SINR of each received CSI-RS and generate a CSI report based on the measured SINR. For example, the CSI report can include a channel quality indicator (CQI), a rank indicator (RI), a precoding matrix indicator (PMI), and / or a layer indicator (LI). The scheduling entity can use the CSI report to select a rank, as well as a precoding matrix and an MCS for the scheduled entity for future downlink transmissions to the scheduled entity. The MCS can be selected from one or more MCS tables, each associated with a particular type of coding (e.g., polar coding, LDPC, etc.) or modulation (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (QAM), 64QAM, 256QAM, etc.). The LI can be used to indicate which column of the precoding matrix for which the PMI has been reported corresponds to the strongest layer codeword corresponding to the maximum reported broadband CQI.

[0118] The RAN node 504 and the wireless communication device 502 can support different types of CSI reports (including L1 measurement reports) and / or different types of measurements. For example, self-contained CSI (e.g., the CSI is sent back to the RAN node 504 in the same time slot in which the RAN node sends the CSI-RS) or non-self-contained CSI (e.g., the CSI is sent back to the RAN node 504 in a time slot later than the time slot in which the RAN node sends the CSI-RS) can be supported. To distinguish between different report / measurement types and measurement configurations, the CSI-RS pilots can be mapped to specific resource elements (REs) and ports for each report / measurement type and report / measurement configuration.

[0119] Figure 6An exemplary CSI resource mapping that supports different reporting / measurement configurations is shown. The CSI resource mapping includes a CSI report setting 602, a CSI resource setting 604, a CSI source setting 606, and a CSI resource 608. Each CSI resource setting 604 includes one or more CSI resource sets 606, and each CSI resource set 606 includes one or more CSI resources 608. In Figure 6 the example shown, a single CSI resource setting (e.g., CSI resource set 0) is shown. However, it should be understood that any suitable number of CSI resource settings 604 can be supported.

[0120] Each CSI report setting 602 may include a reporting quantity that indicates, for example, specific CSI parameters and their granularity (e.g., wideband / subband CQI, PMI, RI, LI, etc.) or L1 parameters (e.g., L1-RSRP, L1-SINR) to be included in the CSI report. The CSI report setting 602 may also indicate the period of the CSI report. For example, the CSI report setting 602 may indicate that the report should be generated periodically, aperiodically, or semi-persistently. For an aperiodic CSI report setting, the CSI report may be sent on the PUSCH. For a periodic CSI report setting, the CSI report may be sent on the PUCCH. For a semi-persistent CSI report setting, the CSI report may be sent on the PUCCH or PUSCH. For example, a media access control (MAC) control element (MAC-CE) may be used to activate or deactivate a semi-persistent CSI report sent on the PUCCH. A semi-persistent CSI report sent on the PUSCH may be triggered using downlink control information (DCI) that is scrambled using a semi-persistent CSI (SP-CP) radio network temporary identifier (SP-CP-RNTI). The CSI report setting 602 may also include corresponding priorities and other suitable parameters.

[0121] Each CSI report setting 602 can be linked to a CSI resource setting 604. Each CSI resource setting 604 can be associated with a specific time-domain behavior of a reference signal. For example, each CSI resource setting 604 can include periodic, semi-persistent, or aperiodic CSI resources 608. For periodic and semi-persistent CSI resource settings 604, the number of configured CSI resource sets 606 can be limited to one. Generally, the CSI resource settings 604 that can be linked to a specific CSI report setting 602 may be restricted by the time-domain behaviors of the CSI resource setting 604 and the CSI report setting 602. For example, an aperiodic CSI report setting 602 can be linked to periodic, semi-persistent, or aperiodic CSI resource settings 604. However, a semi-persistent CSI report setting 602 can only be linked to periodic or semi-persistent CSI resource settings 604. Additionally, a periodic CSI report setting 602 can only be linked to a periodic CSI resource setting 604.

[0122] Each CSI resource set 606 can be associated with a CSI resource type. For example, the CSI resource type can include non-zero power (NZP) CSI-RS resources, SSB resources, or channel state information interference measurement (CSI-IM) resources. Thus, each CSI resource set 606 includes a list of CSI resources 608 of a specific CSI resource type. Additionally, each CSI resource set 606 can also be associated with one or more in a frequency resource set (e.g., OFDM symbols in a bandwidth and / or time slot), a specific set of ports, power, or other suitable parameters.

[0123] Each CSI resource 608 indicates a specific beam (e.g., port), frequency resource, and OFDM symbol on which a wireless communication device can measure a reference signal. For example, each CSI-RS resource 608 can indicate the REs on which CSI-RS pilots or SSBs can be measured from a specific set of ports (e.g., on a specific beam). In Figure 6 the example shown, the CSI-RS resource set 0.1 includes four CSI-RS resources (CSI-RS resource 0.10, CSI-RS resource 0.11, CSI-RS resource 0.12, and CSI-RS resource 0.13). Each CSI resource 608 can also be indexed by a corresponding beam identifier (ID). The beam ID can identify not only a specific beam (e.g., port) but also the resources on which a reference signal can be measured. For example, the beam ID can include a CSI-RS resource indicator (CRI) or an SSB resource indicator (SSBRI).

[0124] A RAN node may configure a wireless communication device with one or more CSI reporting settings 602 and CSI resource settings 604 via, for example, Radio Resource Control (RRC) signaling. For example, the RAN node may configure the wireless communication device with a list of periodic CSI reporting settings 602 indicating associated CSI resource sets 606, which the wireless communication device may use to generate periodic CSI reports. As another example, the RAN node may configure the wireless communication device with a list of aperiodic CSI reporting settings in a CSI-AperiodicTriggerStateList. Each trigger state in the CSI-AperiodicTriggerStateList may include a list of aperiodic CSI reporting settings 602 indicating an associated CSI resource set 606 for channel (and optionally, interference) measurements. As another example, the RAN node may configure the wireless communication device with a list of semi-persistent CSI reporting settings in a CSI-SemiPersistentOnPUSCH TriggerStateList. Each trigger state in the CSI-SemiPersistentOnPUSCH TriggerStateList may include one CSI reporting setting 602 indicating an associated CSI resource set 606. The RAN node may then trigger one or more aperiodic or semi-persistent trigger states using, for example, DCI. As indicated above, MAC-CE may be used to activate or deactivate the semi-persistent CSI reporting setting 602 of CSI reports transmitted on the PUCCH.

[0125] For an L1-RSRP measurement report, a wireless communication device may be configured with a CSI resource setting 604 that has up to 16 CSI resource sets 606. Each CSI resource set 606 may include up to 64 CSI resources 608 in each set. The total number of different CSI resources 608 in all CSI resource sets 606 may not be more than 128. For an L1-SINR measurement report, a wireless communication device may be configured with a CSI resource setting 604 that may include up to 64 CSI resources 608 (e.g., up to 64 CSI-RS resources or up to 64 SSB resources). In an example where the wireless communication device includes two antenna panels and is thus capable of measuring two beams at a time, the wireless communication device may be configured for group-based beam reporting where the wireless communication device may measure beams from different transmit and receive points (TRPs). In this example, a single L1 measurement report may include measurements from two TRPs (e.g., the best beam (highest RSRP or SINR) from a first TRP and the best beam from a second TRP). Here, different CSI-RS or SSB beams from each TRP may be received and measured simultaneously.

[0126] Figure 7 is a diagram illustrating an example of signaling between a wireless communication device (device) 702 and a RAN node 704. The wireless communication device 702 may correspond to Figure 1 , 2 , 4, and / or any UE or scheduled entity shown in 5. Additionally, the RAN node 704 may correspond to Figure 1 , 2 , 4, and / or any base station (e.g., gNB, eNB, or TRP) or scheduling entity shown in 5.

[0127] At 706 and 708, the RAN node 704 may send one or more CSI resource settings and one or more CSI report settings to the wireless communication device 702 to configure the wireless communication device with one or more CSI report settings and associated CSI resource settings. In some examples, the CSI report settings and associated CSI resource settings may be sent to the wireless communication device via RRC signaling.

[0128] In an example where the CSI report settings include periodic L1 measurement report settings, the wireless communication device may utilize the periodic L1 measurement report settings to generate corresponding L1 measurement reports. In an example where the CSI report settings include aperiodic or semi-persistent L1 measurement report settings, at 710, the RAN node 704 may trigger the aperiodic or semi-persistent L1 measurement report settings via, for example, DCI or MAC-CE.

[0129] At 712, the RAN node 704 may perform beam scanning to transmit reference signals (e.g., SSB or CSI-RS) to the wireless communication device 702 on each of multiple beams. At 714, the wireless communication device 702 identifies and measures the RSRP or SINR of the corresponding beam reference signals on one or more configured beams (e.g., based on CSI resources in a CSI resource set associated with CSI reporting settings).

[0130] Measurement reports and procedures can have various characteristics and deployment options. For example, measurement reports can be communicated at various stack layers. For example, at 716, the wireless communication device 702 can send L1 measurement reports (e.g., for SSB or CSI-RS, L1-RSRP or L1-SINR). The measurement reports can be sent to the RAN node 704. The configuration of the measurement reports can be done according to or based on one or more CSI reporting settings. For a particular CSI reporting setting, up to 4 L1 measurements (e.g., up to 4 different beams) can be included in the L1 measurement report. The maximum measurement value can be quantized to 7 bits. For L-RSRP or L1-SINR measurement reports, or if group-based beam reporting is enabled, each additional measurement (up to 3 measurements) included in the L1 measurement report can be a differential measurement (relative to the maximum measurement value) quantized to a 4-bit value. Beam measurements for multiple CSI reporting settings can be sent in a single PUCCH / PUSCH payload (e.g., a single L1 measurement report). Additionally or alternatively, multiple payloads can be used. The number of CSI reporting settings may be limited by the PUCCH / PUSCH payload size. For example, if the payload size is not sufficient to carry all CSI reporting settings, the CSI reporting settings with the lowest priority may be lost.

[0131] CSI reporting can also consider static, semi-static, and / or dynamic channel conditions. For stationary reduced-capability devices such as industrial sensors and video surveillance cameras, the channel conditions may not change frequently. Therefore, the beams and the order of the beams in the L1 measurement report may not change often. Aspects of the present disclosure relate to reducing the payload size in the L1 measurement report. Reducing the L1 measurement report payload size can improve the reporting coverage by maximizing the number of CSI reporting settings that can be sent in the PUCCH / PUSCH payload. Additionally, reducing the L1 measurement report payload size can achieve a reduction in the amount of repetitive information (e.g., CRI / SSBRI) included in each L1 measurement report.

[0132] Figure 8is a diagram illustrating examples of various configurations of L1 measurement reports according to some aspects. In Figure 8 In the example shown, two L1 measurement report configurations 802a and 802b are shown. Each of the L1 measurement report configurations 802a and 802b is associated with a different type of information. Each type of information indicates a different set of information to be included in the L1 measurement reports 802a and 802b. For example, the first L1 measurement report configuration 802a is associated with type 1 information, and the second L1 measurement report configuration 802b is associated with type 2 information.

[0133] Type 1 – The L1 measurement report 802a can include up to four beam measurements (e.g., RSRP or SINR values) 808 and corresponding beam IDs 806 (e.g., CRI or SSBRI) associated with each beam measurement for each CSI report setting 804. In Figure 8 In the example shown, two CSI report settings 804a and 804b are included in each of the L1 measurement reports 802a and 802b. Type 2 – The L1 measurement report 802b includes a reduced payload that contains only the beam measurements 808 for each of the CSI report settings 804a and 804b. The beam measurements 808 for each of the CSI report settings 804a and 804b can include the exact value of the highest (maximum) beam measurement, as well as corresponding differential (diff) values relative to the exact highest value for each of the remaining beam measurements. The exact highest measurement value can be quantized to 7 bits. The differential measurement values (relative to the highest measurement value) can be quantized to 4 bits.

[0134] In some examples, each of the CSI report settings 804a and 804b is associated with a particular selected type of information. The type of information for each of the CSI report settings 804a and 804b can be selected by a wireless communication device or signaled by a RAN node. In some examples, according to the L1 measurement report, a type of information can be applied as Figure 8 shown. In this example, for each of the CSI report settings 804a and 804b included in a particular L1 measurement report 802a or 802b, the selected type of information is the same. In other examples, according to the CSI report setting, a type of information can be applied. In this example, the selected type of information can differ between the CSI report settings included in a particular L1 measurement report.

[0135] Figure 9 According to certain aspects, an example of an L1 measurement report including multiple types of information is shown. In Figure 9In the example shown, two L1 measurement reports 902a and 902b are shown. Each of the L1 measurement reports 902a and 902b includes beam measurements 908 associated with two different CSI report settings 904a and 904b. The selected information type for the first CSI report setting 904a is type 1, and the selected information type for the second CSI report setting 904b is type 2. Thus, for the first CSI report setting 904a, each of the L1 measurement reports 902a and 902b includes up to four beam measurements (e.g., RSRP or SINR values) 908 and corresponding beam IDs 906 (e.g., CRI or SSBRI) associated with each beam measurement. For the second CSI report setting 904b, each of the L1 measurement reports 902a and 902b includes only the beam measurements 908.

[0136] In some examples, the RAN node may be configured to blindly detect the information type included in the L1 measurement report 902a. For example, the RAN node may blindly detect the information type based on the payload size or payload configuration of the PUCCH / PUSCH carrying the L1 measurement report. In other examples, the wireless communication device may explicitly indicate the information type in the L1 measurement report. For example, the L1 measurement report 902b includes type indicators 910a and 910b, each of the type indicators 910a and 910b indicating the corresponding information type associated with the respective CSI report settings 904a and 904b. For example, the type indicator 910a indicates that the first CSI report setting 904a is associated with type 1. Similarly, the type indicator 910b indicates that the second CSI report setting 904b is associated with type 2. In some examples, the type indicators 910a and 910b may be as shown according to the CSI report settings 904a and 904b, as Figure 9 shown. In other examples, the type indicator may be according to the L1 measurement report (e.g., as in the example Figure 8 shown).

[0137] Figure 10 Examples of L1 measurement reports sent over time are shown according to certain aspects. In Figure 10 the example shown, two L1 measurement reports 1002a and 1002b are shown. The first L1 measurement report 1002a may be sent at a first time (t1), and the second L1 measurement report 1002b may be sent at a second time (t2). Thus, the first L1 measurement report 1002a may be considered a previous L1 measurement report compared to the second L1 measurement report 1002b.

[0138] Each of the L1 measurement reports 1002a and 1002b can be a periodic L1 measurement report or a semi-persistent L1 measurement report. Additionally, each of the L1 measurement reports 1002a and 1002b can include respective beam measurements 1008a and 1008b associated with respective CSI report settings 1004a and 1004b. In some examples, the CSI report settings 1004a and 1004b can be the same or different. It should be understood that multiple CSI report settings can be included in each of the L1 measurement reports 1002a and 1002b.

[0139] In some examples, the beam measurements 1008a in the first L1 measurement report 1002a can be arranged in an order configured based on beam measurement values. For example, the first beam measurement in the first L1 measurement report 1002a can have the highest value, the second beam measurement in the first L1 measurement report 1002a can have the second highest value, and so on.

[0140] In one aspect, when the CSI report setting 1004b of the second L1 information report 1002b includes the same set of beam IDs as the CSI report setting 1004a of the previous L1 measurement report 1002a, the wireless communication device can be configured to select type 2 for the CSI report setting 1004b associated with the second L1 measurement report 1002b. The wireless communication device can also be configured to transmit the beam measurements 1008b in the second L1 measurement report 1002b in the same beam ID order as the previous L1 measurement report 1002a. For example, the first L1 measurement report 1002a includes beam measurements 1008a for CRI 1, CRI 2, CRI 3, and CRI 4 in that order. Thus, the second L1 measurement report 1002b can also include beam measurements for CRI 1, CRI 2, CRI 3, and CRI 4 in that order, regardless of the beam measurement values.

[0141] In another aspect, when the second L1 measurement report 1002b includes the same set of beam IDs as the previous L1 measurement report 1002a, the wireless communication device can be configured to select type 2 for the CSI report setting 1004b associated with the second L1 measurement report 1002b. The wireless communication device can also be configured to transmit the beam measurements 1008b in the second L1 measurement report 1002b in the same beam ID order as the previous L1 measurement report 1002a. In Figure 10 the example shown, the information type for the previous L1 measurement report 1002a is configured as type 2. However, regardless of whether the information type of the previous L1 measurement report 1002a is type 1 or type 2, the wireless communication device can configure the information type of the second L1 measurement report 1002b as type 2.

[0142] Otherwise, when the previous L1 measurement report 1002b or the CSI report setting 1004a associated with the previous L1 measurement report 1002a includes a different set of beam IDs, the wireless communication device may be configured to select type 1 for the second L1 measurement report 1002b and, based on the beam measurement values, transmit the beam measurements 1008b in sequence.

[0143] Figure 11 is a diagram showing another example of L1 measurement reports transmitted over time according to some aspects. In Figure 11 the example shown, four L1 measurement reports 1102a–1102d are shown. Each of the L1 measurement reports 1102a–1102d may be a periodic L1 measurement report or a semi-persistent L1 measurement report. Additionally, each of the L1 measurement reports 1102a and 1102b may include corresponding beam measurements 1108a–1108d associated with corresponding CSI report settings 1104a-1104d. In some examples, the CSI report settings 1104a-1104d may be the same or different. It should be understood that multiple CSI report settings may be included in each of the L1 measurement reports 1102a-1102d.

[0144] A first L1 measurement report 1102a is transmitted at a first time (t1), a second L1 measurement report 1102b is transmitted at a second time (t2), and one of a third L1 measurement report 1102c or a fourth L1 measurement report 1102d is transmitted at a third time (t3). Thus, the first L1 measurement report 1102a may be the previous L1 measurement report for the second L1 measurement report 1102b, and the second L1 measurement report 1102b may be the previous L1 measurement report for the third L1 measurement report 1102c. Although the second L1 measurement report 1102b is the previous L1 measurement report relative to the fourth L1 measurement report 1102d, as Figure 11 shown in the example, the first L1 measurement report 1102a may be considered the previous L1 measurement report for the fourth L1 measurement report 1102d.

[0145] In Figure 11 the example shown, each of the CSI report settings 1104a-1104d or each of the L1 measurement reports 1102a-1102d includes the same set of beam IDs (e.g., CRI or SSBRI). Thus, the wireless communication device may be configured to select type 2 for the CSI report settings 1104b-1104d associated with the L1 measurement reports 1102b-1102d. The wireless communication device may also be configured to transmit the beam measurements 1108b-1108d in the L1 measurement reports 1102b-1102d in the same beam ID order as the previous L1 measurement report.

[0146] The beam measurements 1108a in the first L1 measurement report 1102a can be arranged in an order configured based on the beam measurement values. For example, the first beam measurement in the first L1 measurement report 1102a can have the highest value, the second beam measurement in the first L1 measurement report 1102a can have the second highest value, and so on. Additionally, the beam measurements 1108a in the first L1 measurement report 1102a can include absolute beam measurements. For example, the beam measurements 1108a can include the exact value for the highest beam measurement and the corresponding differential values relative to the exact highest value for each remaining beam measurement. The exact highest measurement value can be quantized to 7 bits. The differential measurement values (relative to the highest measurement value) can be quantized to 4 bits.

[0147] In Figure 11 In the example shown, the highest beam measurement in the first L1 measurement report 1102a (e.g., corresponding to the first beam ID, CRI 1) indicates a value of 10 decibels (dB), the second highest beam measurement (e.g., corresponding to the second beam ID, CRI 2) indicates a differential value of -1 dB relative to the highest beam measurement, the third highest beam measurement (e.g., corresponding to the third beam ID, CRI 3) indicates a differential value of -2 dB relative to the highest beam measurement, and the fourth highest beam measurement (e.g., corresponding to the fourth beam ID, CRI 4) indicates a differential value of -3 dB relative to the highest beam measurement. Thus, the first L1 measurement report 1102a indicates the following order of beam measurement values for CRI 1, CRI 2, CRI 3, and CRI 4: 10 dB, 9 dB, 8 dB, and 7 dB.

[0148] In some examples, the beam measurements 1108b in the second L1 measurement report 1102b can include differential beam measurement values relative to the corresponding beam measurements in the first L1 measurement report 1102a. Additionally, the beam measurements 1108b in the second L1 measurement report 1102b can be listed in the same order as the first L1 measurement report 1102a. In Figure 11 In the example shown, the beam measurements 1108b indicate corresponding differential values of -1 dB relative to the corresponding beam measurements 1108a in the first L1 measurement report 1102a for each beam ID (CRI 1, CRI 2, CRI 3, and CRI 4). Thus, the second L1 measurement report 1102b indicates the following order of beam measurement values for CRI 1, CRI 2, CRI 3, and CRI 4: 9 dB, 8 dB, 7 dB, and 6 dB.

[0149] Similarly, the beam measurements 1108c in the third L1 measurement report 1102c can include: differential beam measurement values relative to the corresponding beam measurements in the second L1 measurement report 1102b. Additionally, the beam measurements 1108c in the third L1 measurement report 1102c can be listed in the same order as the second L1 measurement report 1102b. In Figure 11 In the example shown, for each beam ID (CRI1, CRI 2, CRI 3, and CRI 4), the beam measurement 1108c indicates a corresponding difference value of +1 dB relative to the corresponding beam measurement 1108b in the second L1 measurement report 1102b. Thus, the third L1 measurement report 1102c indicates the following order of beam measurement values for CRI 1, CRI 2, CRI 3, and CRI 4: 10 dB, 9 dB, 8 dB, and 7 dB.

[0150] In some examples, instead of including differences compared to a previous differential L1 measurement report 1102b such as the third L1 measurement report 1102c, the wireless communication device can generate an L1 measurement report 1102d that includes difference values compared to a previous absolute L1 measurement report. For example, the beam measurements 1108d in the fourth L1 measurement report 1102d can include: differential beam measurement values relative to the corresponding beam measurements 1108a in the first L1 measurement report 1102a. Additionally, the beam measurements 1108d in the fourth L1 measurement report 1102d can be listed in the same order as the first L1 measurement report 1102a. In Figure 11 In the example shown, the beam measurement 1108d indicates a corresponding difference value of 0 dB relative to the corresponding beam measurement 1108 in the first L1 measurement report 1102a. Thus, the beam measurements 1108d included in the fourth L1 measurement report 1102d indicate the same beam measurements 1108c as in the third beam measurement report 1102, i.e.: 10 dB for CRI1, 9 dB for CRI 2, 8 dB for CRI3, and 7 dB for CRI 4.

[0151] Figure 12 FIG. is an example diagram showing signaling between a wireless communication device (device) 1202 and a RAN node 1204. The wireless communication device 1202 can correspond to Figure 1 、 2 、any one of the UEs or scheduled entities shown in 4 and / or 5. Additionally, the RAN node 1204 can correspond to Figure 1 、 2 、any one of the base stations (e.g., gNB, eNB, or TRP) or scheduled entities shown in 4 and / or 5.

[0152] At 1206 and 1208, the RAN node 1204 may send one or more CSI resource settings and one or more CSI reporting settings to the wireless communication device 1202 to configure the wireless communication device with one or more CSI reporting settings and associated CSI resource settings. In some examples, the CSI reporting settings and associated CSI resource settings may be sent to the wireless communication device via RRC signaling.

[0153] In Figure 12 the example shown, at least one of the CSI reporting settings includes an aperiodic L1 measurement reporting setting. For example, the RAN node 1204 may configure the wireless communication device 1202 with a list of aperiodic CSI reporting settings in the CSI-AperiodicTriggerStateList. Each trigger state in the CSI-AperiodicTriggerStateList may include: a list of aperiodic CSI reporting settings indicating a set of associated CSI resources for channel (and optionally, interference) measurements. At 1210, the RAN node 1204 may trigger one or more aperiodic trigger states using, for example, DCI.

[0154] At 1212, the RAN node 1204 may also send reporting information associated with the aperiodic CSI reporting settings or the aperiodic L1 measurement report. The reporting information may be included in the DCI containing the trigger for the aperiodic L1 measurement report, or in a different message.

[0155] In some examples, the reporting information may include: for example, a list and order of beam measurements associated with the aperiodic CSI reporting settings or the aperiodic L1 measurement report. For example, the reporting information may indicate that a subset of beam IDs associated with the aperiodic CSI reporting settings is included in the aperiodic L1 measurement report. The reporting information may also indicate a first permutation of the beam measurements in the aperiodic L1 measurement report in a specified order by beam ID (e.g., a complete set or a subset included in the CSI reporting settings). In other examples, the reporting information may indicate a second permutation of the beam measurements in the aperiodic L1 measurement report in the same order as a previous L1 measurement report or a previous CSI reporting setting by the corresponding beam ID. The previous L1 measurement report or previous CSI reporting setting may be periodic, aperiodic, or semi-persistent.

[0156] Figure 13 is a conceptual diagram showing an example of a hardware implementation for an exemplary RAN node 1300 using a processing system 1314. For example, the RAN node 130 may be a base station (e.g., gNB) or other scheduling entity, such as Figure 1 、 2 、any one or more of 4, 5, 7, and / or 12 as shown.

[0157] The RAN node 1300 can be implemented using a processing system 1314 that includes one or more processors 1304. Examples of processors 1304 include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functions described throughout this disclosure. In various examples, the RAN node 1300 can be configured to perform any one or more of the functions described herein. That is, the processor 1304 as used in the RAN node 1300 can be used to implement any one or more of the processes and procedures described below. The processor 1304 can in some cases be implemented via a baseband or modem chip, while in other embodiments, the processor 1304 can itself include a number of devices distinct and different from the baseband or modem chip (e.g., in such cases, they can work together to implement the examples discussed herein). As described above, various hardware arrangements and components other than the baseband modem processor can be used in the embodiments, including RF chains, power amplifiers, modulators, buffers, interleavers, adders / accumulators, etc.

[0158] In this example, the processing system 1314 can be implemented using a bus architecture, which is generally represented by the bus 1302. Depending on the specific application and overall design constraints of the processing system 1314, the bus 1302 can include any number of interconnect buses and bridges. The bus 1302 communicatively couples together various circuits including one or more processors (generally represented by the processor 1304), a memory 1305, and a computer-readable medium (generally represented by the computer-readable medium 1306). The bus 1302 can also connect various other circuits such as a timing source, peripherals, voltage regulators, and power management circuits, which are well known in the art and thus will not be described further. The bus interface 1308 provides an interface between the bus 1302 and the transceiver 1310 and the antenna array 1320. The antenna array 1320 can be a single-panel antenna array or a multi-panel antenna array. The transceiver 1310 provides a unit for communicating with various other devices via a transmission medium (e.g., an air interface). A user interface 1312 (e.g., a keyboard, a display, a touch screen, speakers, a microphone, control knobs, etc.) can also be provided. Of course, such a user interface 1312 is optional and can be omitted in some examples.

[0159] The processor 1304 is responsible for managing the bus 1302 and general processing, and includes executing software stored on the computer-readable medium 1306. When executed by the processor 1304, the software causes the processing system 1314 to perform the various functions described hereinafter for any particular device. The computer-readable medium 1306 and the memory 1305 can also be used to store data manipulated by the processor 1304 when executing the software.

[0160] One or more processors 1304 in the processing system can execute the software. The software should be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc., regardless of whether it is called software, firmware, middleware, microcode, hardware description language, or other terms. The software can reside on the computer-readable medium 1306.

[0161] The computer-readable medium 1306 can be a non-transitory computer-readable medium. By way of example, non-transitory computer-readable media include magnetic storage devices (e.g., hard disks, floppy disks, magnetic tape), optical disks (e.g., compact disc (CD) or digital versatile disc (DVD)), smart cards, flash memory devices (e.g., cards, sticks, or key drives), random access memory (RAM), read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), registers, removable disks, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer. For example, computer-readable media can also include carrier waves, transmission lines, and any other suitable medium for transmitting software and / or instructions that can be accessed and read by a computer. The computer-readable medium 1306 can reside within the processing system 1314, be external to the processing system 1314, or be distributed across multiple entities including the processing system 1314. The computer-readable medium 1306 can be located within the processing system 1314, outside the processing system 1314, or be distributed across multiple entities including the processing system 1314. The computer-readable medium 1306 can be embodied in a computer program product. In some examples, the computer-readable medium 1306 can be a part of the memory 1305. For example, the computer program product can include the computer-readable medium in a package material. Those of ordinary skill in the art will recognize how best to implement the functions described throughout this disclosure in light of a particular application and the overall design constraints imposed on the overall system.

[0162] In some aspects of the present disclosure, processor 1304 may include circuitry configured for various functions. For example, processor 1304 may include resource allocation and scheduling circuitry 1342, configured to generate, schedule, and modify resource allocations or authorizations for time-frequency resources. For example, resource allocation and scheduling circuitry 1342 may schedule time-frequency resources within multiple subbands or BWPs of one or more subframes or time slots to carry user data traffic and / or control information to and / or from multiple wireless communication devices.

[0163] In various aspects of the present disclosure, resource allocation and scheduling circuitry 1342 may be configured to schedule resources for transmitting one or more RRC messages including one or more resource settings 1315 (e.g., CSI resource settings) to one or more wireless communication devices for configuration of corresponding resource settings and corresponding reporting settings for each wireless communication device. For example, resource settings 1315 and reporting settings 1316 may be maintained in memory 1305. Resource allocation and scheduling circuitry 1342 may also be configured to schedule resources for transmitting activation or deactivation messages (e.g., via MAC-CE) to wireless communication devices to activate or deactivate semi-persistent reporting settings associated with PUCCH reporting. Additionally, resource allocation and scheduling circuitry 1342 may be configured to schedule resources for transmitting trigger messages (e.g., via DCI) to wireless communication devices to trigger aperiodic or semi-persistent reporting settings associated with PUSCH reporting. Further, resource allocation and scheduling circuitry 1342 may be configured to schedule resources for transmitting (e.g., via DCI containing a trigger message or a different message) reporting information associated with aperiodic reporting settings for transmission to, to indicate a list and / or order of beam measurements to be included in an aperiodic L1 measurement report.

[0164] Resource allocation and scheduling circuitry 1342 may also be configured to schedule resources for periodic, aperiodic, and / or semi-persistent transmission of multiple reference signals on multiple beams. For example, the reference signals may include SSB and / or -RS. Resource allocation and scheduling circuitry 1342 may also be configured to schedule resources for transmitting one or more uplink L1 measurement reports 1318 on one or more PUCCHs or PUSCHs. For example, received uplink L1 measurement reports 1318 received from wireless communication devices may be stored in memory 1305. Resource allocation and scheduling circuitry 1342 may also be configured to execute resource allocation and scheduling instructions (software) 1352 stored in computer-readable medium 1306 to implement one or more of the functions described herein.

[0165] Processor 1304 may also include communication and processing circuitry 1344 configured to communicate with a wireless communication device (e.g., a UE) at a carrier frequency via a respective Uu (cellular) link. In some examples, communication and processing circuitry 1344 may include one or more hardware components that provide a physical structure for performing processing related to wireless communication (e.g., signal reception and / or signal transmission) and signal processing (e.g., processing received signals and / or processing signals for transmission). For example, communication and processing circuitry 1344 may include one or more transmit / receive chains.

[0166] In some embodiments where communication involves receiving information, communication and processing circuitry 1344 may obtain information from components of RAN node 1300 (e.g., from transceiver 1310 that receives information via radio frequency signaling or some other type of signaling adapted to the applicable communication medium), process (e.g., decode) the information, and output the processed information. For example, communication and processing circuitry 1344 may output the information to another component of processor 1304, to memory 1305, or to bus interface 1308. In some examples, communication and processor 1344 may receive one or more signals, messages, other information, or any combination thereof. In some examples, communication and processing circuitry 1344 may receive information via one or more channels. In some examples, communication and processing circuitry 1344 may include the functionality of units for receiving. In some examples, communication and processing circuitry 1344 may include the functionality of units for processing, including units for demodulation, units for decoding, and the like.

[0167] In some embodiments where communication involves transmitting (e.g., sending) information, communication and processing circuitry 1344 may obtain information (e.g., from another component of processor 1304, memory 1305, or bus interface 1308), process (e.g., modulate, encode, etc.) the information, and output the processed information. For example, communication and processing circuitry 1344 may output the information to transceiver 1310 (e.g., for sending information via radio frequency signaling or some other type of signaling adapted to the applicable communication medium). In some examples, communication and processing circuitry 1344 may transmit one or more signals, messages, other information, or any combination thereof. In some examples, communication and processing circuitry 1344 may transmit information via one or more channels. In some examples, communication and processing circuitry 1344 may include the functionality of a unit for transmitting (e.g., a unit for sending). In some examples, communication and processing circuitry 1344 may include the functionality of units for generating, including units for modulation, units for encoding, and the like.

[0168] In some examples, the communication and processing circuitry 1344 may be configured to generate one or more RRC messages and transmit one or more RRC messages (including one or more resource settings 1315 and one or more reporting settings 1316) to one or more wireless communication devices via the transceiver 1310. The communication and processing circuitry 1344 may also be configured to generate an activation or deactivation message and transmit it (e.g., via MAC-CE) to the wireless communication device via the transceiver 1310 to activate or deactivate the semi-persistent reporting setting associated with PUCCH reporting. Additionally, the communication and processing circuitry 1344 may be configured to generate a trigger message and transmit it to the wireless communication device (e.g., via DCI) via the transceiver 1310 to trigger the aperiodic or semi-persistent reporting setting associated with PUSCH reporting. Further, the communication and processing circuitry 1344 may be configured to generate reporting information associated with the aperiodic reporting setting and transmit it (e.g., via DCI including a trigger message or a different message) to the wireless communication device via the transceiver 1310 to indicate the list and / or order of beam measurements to be included in the aperiodic L1 measurement report.

[0169] The communication and processing circuitry 1344 may also be configured to generate and transmit multiple reference signals (SSB and / or CSI RS) on multiple beams using the antenna array 1320 and the transceiver 1310. The communication and processing circuitry 1344 may also be configured to receive one or more uplink L1 measurement reports 1318 on one or more PUCCH or PUSCH from one or more wireless communication devices. The communication and processing circuitry 1344 may also be configured to execute communication and processing instructions (software) 1354 stored in the computer-readable medium 1306 to implement one or more functions described herein.

[0170] The processor 1304 may further include a reporting configuration circuit 1346 configured to select at least one resource setting 1315 and at least one reporting setting 1316 for a wireless communication device. In some examples, the reporting configuration circuit 1346 may further be configured to select a corresponding information type (e.g., type 1 or type 2) for one or more reporting settings 1316. In some examples, the reporting configuration circuit 1346 may further be configured to enable type 1 or type 2 for one or more reporting settings 1316 to allow the wireless communication device to send type 1 or 2 information in an L1 measurement report associated with the reporting setting 1315. In some examples, the reporting configuration circuit 1346 may further be configured to be able to send type 1 or type 2 information according to the reporting setting (e.g., multiple information types may be sent in a single L1 measurement report) or according to the L1 measurement report (e.g., all reporting settings have the same information type in a single L1-measurement report). In some examples, the reporting configuration circuit 1346 may further be configured to configure the wireless communication device or the reporting setting 1316 such that type 2 information for the wireless communication device or the reporting setting 1316 is enabled to include: differential beam measurements compared to a previous differential reporting setting, or a previous differential L1 measurement report or differential beam measurement compared to a previous absolute reporting setting or a previous absolute L1 measurement report.

[0171] In some examples, the reporting configuration circuit 1346 may further be configured to select reporting information for an aperiodic reporting setting or an aperiodic L1 measurement report. For example, the reporting configuration circuit 1346 may be configured to select a list and / or order of beam IDs to include in an L1 measurement report or within all L1 measurement reports associated with a particular reporting setting. In some examples, the list and / or order may be selected to be the same order as the previous reporting setting of the L1 measurement report or the previous L1 measurement report used by the wireless communication device to generate the same or different reporting settings. The reporting configuration circuit 1346 may further be configured to execute reporting configuration instructions (software) 1356 stored in the computer-readable medium 1306 to implement one or more of the functions described herein.

[0172] The processor 1304 may also include an L1 measurement report processing circuit 1348 configured to receive and process L1 measurement reports 1318 received from a wireless communication device. The L1 measurement reports 1318 may include beam measurement information, the beam measurement information including beam measurements (e.g., RSRP or SINR), each beam measurement corresponding to a respective beam ID. The beam ID may be, for example, a CRI or SSBRI that identifies a particular beam (e.g., port), frequency resource, and OFDM symbol on which the wireless communication device may measure a reference signal (e.g., SSB or CSI-RS). The L1 measurement reports 1318 may include up to four beam IDs and corresponding beam measurements configured in the associated reporting settings 1316. In some examples, the L1 measurement reports 1318 may include information of a first information type (Type 1) or a second information type (Category 2). A Type 1 - L1 measurement report may include beam measurements and corresponding beam IDs associated with each beam measurement. A Type 2 - L1 measurement report may include a reduced payload that contains only beam measurements.

[0173] In some examples, the L1 measurement reports 1318 may include a type indicator that indicates the information type (Type 1 or Type 2) for the L1 measurement report 1318, or a respective type identifier that indicates the corresponding information type for the beam measurements associated with each reporting setting included in the L1 measurement report 1318. In some examples, the L1 measurement report processing circuit 1348 may be configured to blindly detect the information type associated with the L1 measurement report, or the corresponding information type associated with each set of beam measurements corresponding to the reporting settings included in the L1 measurement report. For example, the L1 measurement report processing circuit 1348 may be configured to detect the information type based on the size of the PUCCH / PUSCH payload or the configuration of the PUCCH / PUSCH payload carrying the L1 measurement report 1318.

[0174] The L1 measurement report processing circuit 1348 can also be configured to determine the corresponding beam ID for each beam measurement received in the type 2 L1 measurement report 1318. For periodic or semi-persistent L1 measurement reports 1318, the L1 measurement report processing circuit 1348 can be configured to identify the corresponding beam ID based on the order of the beam IDs included in the previously received L1 measurement report 1318. For example, the L1 measurement report processing circuit 1348 can be configured to determine that the previously received L1 measurement report or the reporting setting 1316 associated with the previously received L1 measurement report 1318 includes the same set of beam IDs as the current L1 measurement report 1318. In this example, the L1 measurement report processing circuit 1348 can assume that the order of the beam IDs in the current L1 measurement report 1318 is the same as the order of the beam IDs in the previous L1 measurement report. In some examples, based on the reporting setting 1316 for the current L1 measurement report, the previous L1 measurement report 1318 can be a differential L1 measurement report or an absolute L1 measurement report.

[0175] For aperiodic L1 measurement reports, the L1 measurement report processing circuit 1348 can also be configured to identify the corresponding beam ID based on the reporting information provided to the wireless communication device. For example, the reporting information can include an explicit list and order of beam IDs. As another example, the reporting information can instruct the wireless communication device to use the same beam ID order as the previous reporting setting or L1 measurement report. The L1 measurement report processing circuit 1348 can also be configured to execute L1 measurement report processing instructions (software) 1358 stored in the computer-readable medium 1306 to implement one or more of the functions described herein.

[0176] Figure 14 is a flowchart 1400 of a method for receiving an L1 measurement report based on the information type of the L1 measurement report according to some aspects. As described below, some or all of the illustrated features may be omitted in specific embodiments within the scope of the present disclosure, and some illustrated features may not be required in all example embodiments. In some examples, as described above and Figure 13 as shown, the method can be performed by the RAN node 1300, by a processor or processing system, or by any suitable unit for performing the functions.

[0177] At block 1402, the RAN node can send at least one reporting setting for a layer 1 (L1) measurement report to the wireless communication device. Each of the at least one reporting settings can be associated with a corresponding selected information type selected from a first information type and a second information type. For example, the reporting configuration circuit 1346 and the communication and processing circuit 1344 and the transceiver 1310 shown and described above in connection with Figure 13 can provide the unit for sending the at least one reporting setting.

[0178] At block 1404, the RAN node may receive, from a wireless communication device, an L1 measurement report of a selected information type based on a first reporting setting for at least one reporting setting. The L1 measurement report may include first beam measurement information, the first beam measurement information including first beam measurements, each first beam measurement corresponding to one of a first set of a plurality of beams used for communicating with the wireless communication device. In some examples, the RAN node may transmit reference signals on each of the first set of a plurality of beams. Here, each respective beam may be associated with a respective beam identifier. The respective beam identifier may include a respective reference signal resource indicator associated with the reference signal and the respective beam. In some examples, the reference signal may include an SSB or a CSI-RS. In some examples, the first beam measurement information includes a respective reference signal received power (RSRP) measurement for each of the first set of a plurality of beams, or a respective signal-to-interference-plus-noise (SINR) measurement for each of the first set of a plurality of beams. For example, as described above in connection with Figure 13 the L1 reporting processing circuitry 1348 and the communication and processing circuitry 1344 and transceiver 1310 shown and described may provide a unit for receiving the L1 measurement report.

[0179] At block 1406, the RAN node may determine whether the selected information type for the first reporting setting associated with the L1 measurement report is a first information type (type 1) or a second information type (type 2). In some examples, the RAN node may determine the selected information type for the first reporting setting based on a type indicator included in the L1 measurement report. In other examples, the RAN node may blindly detect the information type for the first reporting setting.

[0180] When the information type is type 1 (the Y branch of block 1406), at block 1408, the RAN node may determine that the L1 measurement report further includes a respective beam identifier corresponding to each first beam measurement. When the information type is type 2 (the N branch of block 1406), at block 1410, the RAN node may determine that the L1 measurement report excludes the respective beam identifier corresponding to each first beam measurement. For example, as described above in connection with Figure 13 the L1 measurement reporting processing circuitry 1348 shown and described may provide a unit for determining whether the selected information type is type 1 or type 2.

[0181] In some examples, the L1 measurement report is a periodic or semi-persistent L1 measurement report that includes type 2 information. In this example, the first beam measurement in the first beam measurement information is arranged in the same order as the previous L1 measurement report or the previous reporting configuration of the previous L1 measurement report. In some examples, the first beam measurement in the first beam measurement information includes an absolute beam measurement. For example, the absolute beam measurement may include the exact value of the highest beam measurement for the first beam measurement and the corresponding differential values relative to the exact values of each remaining beam measurement for the first beam measurement. In other examples, the first beam measurement in the first beam measurement information includes a differential beam measurement relative to the previous L1 measurement report or the previous reporting configuration of the previous L1 measurement report. In some examples, the previous L1 measurement report includes additional differential beam measurements relative to another previous L1 measurement report or another previous reporting configuration. In other examples, the previous L1 measurement report includes an absolute beam measurement.

[0182] In some examples, the L1 measurement report is an aperiodic L1 measurement report. In this example, the RAN node may also send report information associated with the first reporting configuration to the wireless communication device. In some examples, the report information may indicate a first arrangement in which the first beam measurements in the L1 measurement report are in a specified order of the corresponding beam identifiers. In other examples, the report information may indicate a second arrangement in which the first beam measurements in the L1 measurement report are in the same order as the previous L1 measurement report or the previous reporting configuration of the previous L1 measurement report of the corresponding beam identifiers.

[0183] In some examples, based on the selected information type for a second reporting configuration for at least one reporting configuration, the L1 measurement report may further include second beam measurement information, where the second beam measurement information includes second beam measurements, each second beam measurement corresponding to one beam in a second set of a plurality of beams. In some examples, in response to the selected information type for the first reporting configuration including a first information type, the L1 measurement report may include first beam measurement information and the corresponding beam identifiers corresponding to each first beam measurement. Additionally, in response to the selected information type for the second reporting configuration including a second information type, the L1 measurement report may further include second beam measurement information and exclude the corresponding beam identifiers corresponding to each second beam measurement. In other examples, in response to the selected information type for the first reporting configuration including a second information type, the L1 measurement report includes first beam measurement information and excludes the corresponding beam identifiers corresponding to each second beam measurement. Additionally, in response to the selected information type for the second reporting configuration including a first information type, the L1 measurement report may further include second beam measurement information and the corresponding beam identifiers corresponding to each second beam measurement.

[0184] In some examples, in response to the selected information type being the same for each of a first reporting setting and a second reporting setting, the L1 measurement report includes first beam measurement information and second beam measurement information. In some examples, in response to the selected information type being different for each of the first reporting setting and the second reporting setting, the L1 measurement report includes a respective type indicator for the respective selected information type for each of the first reporting setting and the second reporting setting. In other examples, in response to the respective selected information type being the same for each of the first reporting setting and the second reporting setting, the L1 measurement report includes a single type indicator corresponding to the respective selected information type for each of the first reporting setting and the second reporting setting.

[0185] In one configuration, a radio access network (RAN) node (e.g., a base station) includes a unit for sending at least one reporting setting for a layer 1 (L1) measurement report to a wireless communication device. Each of the at least one reporting settings is associated with a respective selected information type selected from a first information type and a second information type. The RAN node further includes: a unit for receiving an L1 measurement report from the wireless communication device based on the selected information type of a first reporting setting of the at least one reporting settings. The L1 measurement report includes first beam measurement information, the first beam measurement information including a first beam measurement, each first beam measurement corresponding to one beam in a first set of a plurality of beams for communicating with the wireless communication device. In response to the selected information type for the first reporting setting including the first information type, the L1 measurement report further includes a respective beam identifier corresponding to each first beam measurement. In response to the selected information type for the first reporting setting including the second information type, the L1 measurement report excludes the respective beam identifier corresponding to each first beam measurement.

[0186] In one aspect, the above-mentioned unit for sending at least one reporting setting for an L1 measurement report to a wireless communication device and the unit for receiving an L1 measurement report based on the selected information type of a first reporting setting of the at least one reporting settings from the wireless communication device can be Figure 13 the processor 1304 shown in being configured to perform the functions described by the above-mentioned unit. For example, the above-mentioned unit for sending at least one reporting setting can include a reporting configuration circuit 1346, and a communication and processing circuit 1344 and a transceiver 1310, as Figure 13 shown in. As another example, the above-mentioned unit for the L1 measurement report based on a first reporting setting from the wireless communication device can include an L1 reporting processing circuit 1348, and Figure 13 the communication and processing circuit 1344 and the transceiver 1310 shown in. In another aspect, the above-mentioned unit can be a circuit or any device configured to perform the functions described by the above-mentioned unit.

[0187] Figure 15 is a block diagram illustrating an example of a hardware implementation of a wireless communication device 1500 employing a processing system 1514. For example, the wireless communication device 150 may correspond to any one of the UEs or scheduled entities shown and described above with reference to Figure 1 、 2 、4, 5, 7, and / or 12.

[0188] In accordance with various aspects of the present disclosure, an element, any portion of an element, or any combination of multiple elements may be implemented using a processing system 1514 that includes one or more processors 1504. The processing system 1514 may be substantially the same as the processing system 1314 shown in Figure 13 , including a bus interface 1508, a bus 1502, a memory 1505, a processor 1504, and a computer-readable medium 1506. Additionally, the wireless communication device 1500 may include a user interface 1512, a transceiver 1510, and an antenna array 1520, which are substantially similar to those described above in Figure 13 . That is, the processor 1504, as used in the wireless communication device 150, may be used to implement any one or more of the processes described below.

[0189] In some aspects of the present disclosure, the processor 1504 may include circuitry configured for various functions. For example, the processor 1504 may include communication and processing circuitry 1542 configured to communicate with a RAN node (e.g., a base station, such as a gNB) via the transceiver 1510. The communication and processing circuitry 1542 may include one or more hardware components that provide a physical structure for performing processing related to wireless communication (e.g., signal reception and / or signal transmission) and signal processing (e.g., processing received signals and / or processing signals for transmission). For example, the communication and processing circuitry 1542 may be configured to exchange control information and data with a RAN node via one or more subframes, time slots, and / or mini-slots.

[0190] In some examples, the communication and processing circuitry 1542 may be configured to receive, via the transceiver 1510, one or more RRC messages from a serving RAN node, the one or more RRC messages including one or more resource settings 1515 (e.g., CSI resource settings) and one or more reporting settings 1516 (e.g., CSI reporting settings). For example, the resource settings 1515 and the reporting settings 1516 are maintained in the memory 1505 for subsequent use.

[0191] The communication and processing circuitry 1542 may also be configured to receive, via transceiver 1510, activation or deactivation messages (e.g., via MAC-CE) from a RAN node to activate or deactivate semi-persistent reporting settings associated with PUCCH reporting. Additionally, the communication and processing circuitry 1542 may be configured to receive, via transceiver 1510, trigger messages (e.g., via DCI) from a RAN node to trigger aperiodic or semi-persistent reporting settings associated with PUSCH reporting. Additionally, the communication and processing circuitry 1542 may be configured to receive, via transceiver 1510, reporting information associated with aperiodic reporting settings (e.g., via DCI containing a trigger message or a different message), the reporting information indicating a list and / or order of beam measurements to be included in an aperiodic L1 measurement report.

[0192] The communication and processing circuitry 1542 may also be configured to receive multiple reference signals (SSB and / or -RS) on multiple beams using antenna array 1520 and transceiver 1510. The communication and processing circuitry 1542 may also be configured to send an uplink L1 measurement report to a RAN node, the uplink L1 measurement report including beam measurement information (BMI) 1518 on a PUCCH or PUSCH. The communication and processing circuitry 1542 may also be configured to execute communication and processing instructions (software) 1552 stored in computer-readable medium 1506 to implement one or more functions described herein.

[0193] The processor 1504 may also include beam search and measurement circuitry 1544 configured to control antenna array 1520 and transceiver 1510 to search for and identify multiple beams during downlink beam scanning. The beam search and measurement circuitry 1544 may also be configured to receive corresponding reference signals (e.g., SSB or CSI-RS) and measure a corresponding RSRP, SINR, or other suitable beam measurement of the corresponding reference signal on each beam in a set of multiple beams identified in reporting settings 1516 and associated resource settings 1515. For example, reporting settings 1516 may be associated with resource settings 1515 configured to include one or more resource sets, each resource set including multiple beam IDs that indicate a set of beams on which to obtain beam measurements and associated reference signal resources. The obtained beam measurements may be stored as BMI 1518 in, for example, memory 1505 for generating an L1 measurement report including BMI 1518. The beam search and measurement circuitry 1544 may also be configured to execute beam search and test instructions (software) 1554 stored in computer-readable medium 1506 to implement one or more functions described herein.

[0194] The processor 1504 may further include an L1 measurement report generation circuit 1546 configured to generate an L1 measurement report (e.g., a current L1 measurement report) based on a reporting setting 1516 for obtaining the BMI 1518 and a corresponding resource setting 1515. The L1 measurement report generation circuit 1546 may also operate with the communication and processing circuit 1542 and the transceiver 1510 to send the current L1 measurement report to a RAN node. The current L1 measurement report may include the BMI 1518, which includes beam measurements (e.g., RSRP or SINR), each beam measurement corresponding to a respective beam ID. For example, the beam ID may be a CRI or SSBRI that identifies a specific beam (e.g., a port), a frequency resource, and an OFDM symbol on which a reference signal (e.g., an SSB or CSI-RS) is measured. The current L1 measurement report may include up to four beam IDs and the corresponding beam measurements configured in the reporting setting 1516.

[0195] In some examples, the current L1 measurement report may include information of a first information type (type 1) or a second information type (type 2). The type 1 - L1 measurement report may include beam measurements and the corresponding beam IDs associated with each beam measurement. The type 2 - L1 measurement report may include a reduced payload that contains only beam measurements. The L1 measurement report generation circuit 1546 may also be configured to select the information type (e.g., type 1 or type 2) for the reporting setting 1516. In some examples, the selected information type may be indicated in the reporting setting 1516 or located in the reporting information received from the RAN node related to the reporting setting 1517 (e.g., an aperiodic reporting setting) or the current L1 measurement report (e.g., an aperiodic L1 measurement report). For example, the reporting information may include an explicit list and order of beam IDs to be included in the type 2 - L1 measurement report (e.g., the beam measurements corresponding to the beam IDs). As another example, the reporting information may indicate to the wireless communication device 1500 to use the same beam ID order as the previous reporting setting or the previous L1 measurement report sent to the RAN node for the type 2 - L1 measurement report.

[0196] In other examples, the L1 measurement report generation circuit 1546 may select an information type based on the configuration of a previous L1 measurement report or previous reporting settings used for the previous L1 measurement report. In this example, the current L1 measurement report may be a periodic or semi-persistent L1 measurement report, and the previous L1 measurement report may be periodic, semi-persistent, or aperiodic and of any information type. For example, when a previous L1 measurement report includes (or is configured by previous reporting settings to include) the same set of beam IDs (e.g., CRI or SSBRI) as the current L1 measurement report, the L1 measurement report generation circuit 1546 may select a second information type (type 2) for the selected reporting settings associated with the current L1 measurement report. Otherwise, the L1 measurement report generation circuit 1546 may select a first information type (type 1) for the selected reporting settings associated with the current L1 measurement report.

[0197] In an example where the information type is selected as the second information type based on the same set of beam IDs included in the previous L1 measurement report, the L1 measurement report generation circuit 1546 may include beam measurements in the current L1 measurement report arranged in the same order as the beam IDs in the previous L1 measurement report. In some examples, the L1 measurement report circuit 1546 may include absolute beam measurements (e.g., the highest accurate value and remaining different beam values) included in the BMI 1518 in the current L1 measurement report. In other examples, the L1 measurement report generation circuit 1546 may compare the BMI 1518 for the current L1 measurement result report with the BMI of the previous L1 measurement to generate differential beam measurement values relative to the corresponding beam measurements in the previous L1 measurement report. The L1 measurement report generation circuit may include the differential beam measurements for each beam ID in the current L1 measurement report and store the differential beam measurements in the BMI 1518 for the current L1 measurement report. In some examples, based on the reporting settings 1516 for the current L1 measurement report, the previous L1 measurement report may be a differential L1 measurement report or an absolute L1 measurement report.

[0198] The L1 measurement report generation circuit 1546 may also be configured to select a corresponding information type for each reporting setting to be included in the current L1 measurement report and populate the current L1 measurement report based on the corresponding information types of each reporting setting included in the current L1 test report. In some examples, the L1 measurement report generation circuit 1546 may be configured to include only reporting settings 1516 of the same information type in the current L1 measurement report. This may be a configuration of the wireless communication device 1500 or a configuration associated with at least one reporting setting to be included in the current L1 measurement report. In other examples, the L1 measurement report generation circuit 1546 may be configured to include different types of reporting settings 1516 in the current L1 measurement report.

[0199] In some examples, the L1 measurement report generation circuit 1546 may also be configured to include a type indicator in the current L1 measurement report, where the type indicator indicates the type of information (type 1 or type 2) for the current L1 measurement report. In this example, each report setting 1516 included in the current L1 measurement report is associated with the same type of information. The L1 measurement report generation circuit 1546 may also be configured to include a corresponding type indicator that indicates the corresponding type of information for the beam measurement associated with each report setting included in the current L1 measurement report. In this example, each report setting 1516 included in the current L1 measurement report may be associated with the same or different types of information. The L1 measurement report generation circuit 1546 may also be configured to execute L1 measurement report generation instructions (software) 1556 stored in the computer-readable medium 1506 to implement one or more of the functions described herein.

[0200] Figure 16 is a flowchart 1600 of a method for transmitting an L1 measurement report based on the type of information of the L1 measurement report according to some aspects. As described below, some or all of the illustrated features may be omitted in certain embodiments within the scope of the present disclosure, and some of the illustrated features may not be required when implementing all examples. In some examples, as described above and Figure 15 shown, the method may be performed by the wireless communication device 1500, by a processor or processing system, or by any suitable unit for performing the functions.

[0201] At block 1602, the wireless communication device may receive at least one report setting for a layer 1 (L1) measurement report from a radio access network (RAN) node. Each of the at least one report settings may be associated with a corresponding selected information type selected from a first information type and a second information type. For example, the communication and processing circuit 1542 and the transceiver 1510 described above in connection with Figure 15 shown and described may provide the unit for receiving the at least one report setting.

[0202] At block 1604, the wireless communication device may obtain first beam measurement information including first beam measurements, each first beam measurement corresponding to one beam in a first set of a plurality of beams used for communication with a RAN node. The first beam measurement information may be based on a first reporting setting of at least one reporting setting. In some examples, the wireless communication device may receive reference signals on each beam in the first set of a plurality of beams. Here, each corresponding beam may be associated with a corresponding beam identifier. The corresponding beam identifier may include a corresponding reference signal resource indicator associated with the reference signal and the corresponding beam (e.g., SSBRI or CRI). In some examples, the reference signal may include SSB or CSI-RS. In some examples, the first beam measurement information includes corresponding reference signal received power (RSRP) measurements for each beam in the first set of a plurality of beams, or corresponding signal-to-interference-plus-noise (SINR) measurements for each beam in the first set of a plurality of beams. For example, as described above in connection with Figure 15 the beam search and measurement circuitry 1544 shown and described, as well as the communication and processing circuitry 1542 and transceiver 1510, may provide units for obtaining the first beam measurement information.

[0203] At block 1606, the wireless communication device may send an L1 measurement report including the first beam measurement information to the RAN node based on a selected information type for the first reporting setting. In response to the selected information type for the first reporting setting being a first information type, the L1 measurement report may further include corresponding beam identifiers corresponding to each first beam measurement. In response to the selected information type for the first reporting setting being a second information type, the L1 measurement report may further exclude the corresponding beam identifiers. For example, as described above in connection with Figure 15 the L1 measurement report generation circuitry 1546 shown and described, as well as the communication and processing circuitry 1542 and transceiver 1510, may provide units for sending the L1 measurement report to the RAN node.

[0204] In some examples, the L1 measurement report is a periodic or semi-persistent L1 measurement report that includes type 2 information. In this example, the first beam measurement in the first beam measurement information is arranged in a first order of corresponding beam identifiers in the same order as a previous L1 measurement report or a previous reporting configuration of a previous L1 measurement report. In some examples, the first beam measurement in the first beam measurement information includes an absolute beam measurement. For example, the absolute beam measurement may include an accurate value of the highest beam measurement of the first beam measurement and corresponding difference values of accurate values for each remaining beam measurement in the first beam measurement. In other examples, the first beam measurement in the first beam measurement information includes a differential beam measurement relative to a previous L1 measurement report, or a previous reporting configuration of a previous L1 measurement report. In some examples, the previous L1 measurement report includes additional differential beam measurements relative to another previous L1 measurement report or another previous reporting configuration. In other examples, the previous L1 measurement report includes an absolute beam measurement.

[0205] In some examples, the L1 measurement report is an aperiodic L1 measurement report. In this example, the wireless communication device may also receive reporting information associated with a first reporting configuration from a RAN node. In some examples, the reporting information may indicate: a first arrangement of the first beam measurement in the L1 measurement report in a specified order by beam identifier. In other examples, the reporting information may indicate a second arrangement of the first beam measurement in the L1 measurement report in the same order as a previous L1 measurement report or a previous reporting configuration of a previous L1 measurement report by corresponding beam identifiers.

[0206] Figure 17 FIG. 1700 is a flow chart of another method of transmitting an L1 measurement report based on the information type of the L1 measurement report according to some aspects. As described below, some or all of the illustrated features may be omitted in a particular implementation within the scope of the present disclosure, and some of the illustrated features may not be required in implementing all examples. In some examples, as described above and as Figure 15 shown in, the method may be performed by a wireless communication device 1500, by a processor or processing system, or by any suitable unit for performing the functions.

[0207] At block 1702, the wireless communication device may receive at least one reporting configuration for a layer 1 (L1) measurement report from a radio access network (RAN) node. Each of the at least one reporting configurations may be associated with a corresponding selected information type selected from a first information type and a second information type. For example, the communication and processing circuitry 1542 and the transceiver 1510 described above in connection with Figure 15 shown and described may provide a unit for receiving the at least one reporting configuration.

[0208] At block 1704, the wireless communication device may obtain first beam measurement information including first beam measurements, each first measurement corresponding to one beam in a first set of multiple beams for communicating with a RAN node. The first beam measurement information may be based on a first reporting setting of at least one reporting setting. In some examples, the wireless communication device may receive reference signals on each beam in the first set of multiple beams. Here, each corresponding beam may be associated with a corresponding beam identifier. The corresponding beam identifier may include a corresponding reference signal resource indicator associated with the reference signal and the corresponding beam (e.g., SSBRI or CRI). In some examples, the reference signal may include SSB or CSI-RS. In some examples, the first beam measurement information includes corresponding reference signal received power (RSRP) measurements for each beam in the first set of multiple beams, or corresponding signal-to-interference-plus-noise (SINR) measurements for each beam in the first set of multiple beams. For example, as described above in connection with Figure 15 the beam search and measurement circuitry 1544 shown and described, and the communication and processing circuitry 1542 and transceiver 1510 may provide units for obtaining the first beam measurement information.

[0209] At block 1706, the wireless communication device may obtain second beam measurement information, the second beam measurement information including second beam measurements, each second beam measurement corresponding to one beam in a second set of multiple beams. The second beam measurements may be obtained based on a second reporting setting of at least one reporting setting. The second beam measurement information may be obtained in a manner similar to the first beam measurement information. For example, as described above in connection with Figure 15 the beam search and measurement circuitry 1544 shown and described, and the communication and processing circuitry 1542 and transceiver 1510 may provide units for obtaining the second beam measurement information.

[0210] At block 1708, the wireless communication device may send an L1 measurement report including the first beam measurement information and the second beam measurement information to the RAN node based on the types of information selected for the first reporting setting and the second reporting setting, respectively. In response to the selected information type for the first reporting setting being a first information type, the L1 measurement report may further include the corresponding beam identifiers corresponding to each first beam measurement. In response to the selected information type for the first reporting setting being a second information type, the L1 measurement report may also exclude the corresponding beam identifiers. For example, as described above in connection with Figure 15 the L1 measurement report generation circuitry 1546 shown and described, and the communication and processing circuitry 1542 and transceiver 1510 may provide units for sending the L1 measurement report to the RAN node.

[0211] In some examples, in response to the selected information type for the first reporting setting including a first information type, the L1 measurement report may include first beam measurement information and corresponding beam identifiers corresponding to each of the first beam measurements. Additionally, in response to the selected information type for the second reporting setting including a second information type, the L1 measurement report may further include second beam measurement information and exclude the corresponding beam identifiers corresponding to each of the second beam measurements. In other examples, in response to the selected information type for the first reporting setting including a second information type, the L1 measurement report may further include first beam measurement information and exclude the corresponding beam identifiers corresponding to each of the first beam measurements. Additionally, in response to the selected information type for the second reporting setting including a first information type, the L1 measurement report may further include second beam measurement information and corresponding beam identifiers corresponding to each of the second beam measurements.

[0212] In some examples, in response to the selected information type for each of the first reporting setting and the second reporting setting being the same, the L1 measurement report may further include first beam measurement information and second beam measurement information. In some examples, in response to the respective selected information types for each of the first reporting setting and the second reporting setting being different, the L1 measurement report may further include: corresponding type indicators corresponding to the respective selected information types for each of the first reporting setting and the second reporting setting. In other examples, in response to the respective selected information types for each of the first reporting setting and the second reporting setting being the same, the L1 measurement report may further include: a single type indicator corresponding to the respective selected information types for each of the first reporting setting and the second reporting setting.

[0213] In one configuration, a wireless communication device (e.g., a UE) includes: a unit for receiving, from a radio access network (RAN) node, at least one reporting setting for a layer 1 (L1) measurement report. Each reporting setting of the at least one reporting setting is associated with a respective selected information type selected from a first information type and a second information type. The wireless communication device further includes a unit for obtaining first beam measurement information including first beam measurements based on a first reporting setting of the at least one reporting setting, each first beam measurement corresponding to one beam in a first set of a plurality of beams for communicating with the RAN node. The wireless communication device further includes: a unit for sending an L1 measurement report including the first beam measurement information to the RAN node based on the selected information type for the first reporting setting. When the selected information type for the first reporting setting includes the first information type, the L1 measurement report further includes a respective beam identifier corresponding to each first beam measurement. When the selected information type for the first reporting setting includes the second information type, the L1 measurement report excludes the respective beam identifier corresponding to each first beam measurement.

[0214] In one aspect, the at least one reporting setting unit for receiving the L1 measurement report and sending the L1 measurement report including the first beam information by obtaining the first beam measurement information based on the first reporting setting may be Figure 15 the processor 1504 shown in [FIGURE] and configured to perform the functions of the above unit. For example, the above unit for receiving at least one reporting setting may include Figure 15 the communication and processing circuit 1542 and the transceiver 1510 shown in [FIGURE]. As another example, the above unit for obtaining the first beam measurement information based on the first reporting setting may include the beam search and measurement circuit 1544, together with the communication and processing circuit 1542 and the transceiver 1510, as Figure 15 shown in [FIGURE]. As another example, the above unit for sending the L1 measurement report including the first beam information may include the L1 measurement report generation circuit 1546, and the communication and processing circuit 1542 and the transceiver 1510, as Figure 15 shown in [FIGURE]. In another aspect, the above unit may be a circuit or any device configured to perform the functions of the above unit.

[0215] Figure 18 is a flowchart 1800 of a method for receiving a measurement report based on an information type of the measurement report according to some aspects. As described below, some or all of the illustrated features may be omitted in certain embodiments within the scope of the present disclosure, and some of the illustrated features may not be required to implement all examples. In some examples, as described above and Figure 13As shown, the method can be performed by the RAN node 1300, by a processor or processing system, or by any suitable unit for performing the functions.
