Description

[Technical field]

[0001] cross reference This patent application claims priority to U.S. Provisional Patent Application No. 62 / 481,658, filed April 4, 2017, by Subramanian et al., entitled "Beam Management Using Synchronization Signals Through Channel Feedback Framework," and U.S. Patent Application No. 15 / 943,586, filed April 2, 2018, by Subramanian et al., entitled "Beam Management Using Synchronization Signals Through Channel Feedback Framework," each of which is assigned to the present application.

[0002] The following relates generally to wireless communications, and more particularly to beam management using a synchronization signal (SS) over channel feedback framework. [Background technology]

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasts, and the like. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, and Orthogonal Frequency Division Multiple Access (OFDMA) systems, (e.g., Long Term Evolution (LTE) systems, or New Radio (NR) systems). A wireless multiple-access communication system may include several base stations or access network nodes, each simultaneously supporting communication for multiple communication devices, sometimes known as User Equipment (UE).

[0004] In some wireless communication systems (e.g., systems supporting millimeter wave (mmW) communications), beamforming may be used to overcome the relatively high path loss associated with frequencies in these systems. To support beamformed transmissions, the communicating wireless devices (e.g., base stations and UEs) may be operable to find and maintain a suitable beam for a given communication link. The set of procedures and protocols required for this task may be referred to as beam management. As an example, beam management may be based on a UE observing beamformed downlink signals and reporting one or more performance metrics for each beamformed signal to a base station. For example, a channel state information reference signal (CSI-RS) associated with multiple transmit beams may be provided, and the channel state feedback may include a report indicative of channel information for the best transmit beam. Improvements in providing channel feedback based on transmit beams from a base station are desired. Summary of the Invention [Means for solving the problem]

[0005] The described techniques relate to an improved method, system, device, or apparatus that supports beam management using a synchronization signal (SS) over a channel feedback framework. In aspects of the present disclosure, a user equipment (UE) may report metrics (e.g., received signal power, beam identifier) ​​for SS beams following the same framework used for channel state information reference signal (CSI-RS) reporting. Since some wireless systems (e.g., mmW systems) employ beamformed directional transmission (e.g., of SS and other signals) to overcome path loss complexities, consideration to efficient reporting of beamformed signal characteristics (i.e., beam management) may benefit the system. Thus, beam management may be achieved at least in part based on reporting one or more metrics of beamformed SS over a channel feedback framework.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Some wireless communication systems employ beamforming to overcome communication range limitations due to the relatively high path loss associated with frequencies in the system. To support these beamformed transmissions, the communicating devices may periodically measure one or more metrics associated with one or more beamformed transmissions as a process that is part of beam management. For example, beam management may include beam selection and switching, beam restoration, beam optimization, etc. For example, a base station may select a more suitable beam when a previously selected beam becomes useless (e.g., due to device movement or some other factor affecting communication). Since synchronization signals (SS) are intended to be broadcast over a wide coverage area in a beamformed manner, SS represents a promising complement to existing beam management techniques. Thus, as further described below, SS may assist beam management via a channel feedback framework.

[0030] Aspects of the present disclosure are first described in the context of a wireless communication system. Aspects of the present disclosure are then illustrated by and described with reference to configuration message and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow charts relating to a beam-aware handover procedure for a multi-beam access system.

[0031] FIG. 1 illustrates an example of a wireless communication system 100 according to various aspects of the present disclosure. The wireless communication system 100 includes a base station 105, a user equipment (UE) 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, a LTE-Advanced (LTE-A) network, or a 5G New Radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (i.e., mission-critical) communication, low latency communication, and communication with low-cost and low-complexity devices. The wireless communication system 100 may support efficient use of resources by allowing SSs to report to beam management via reuse of a channel state information reference signal (CSI-RS) reporting framework.

[0032] The base stations 105 may wirelessly communicate with the UEs 115 via one or more base station antennas. Each base station 105 may provide communication coverage for a respective geographic coverage area 110. The communication links 125 illustrated in the wireless communication system 100 may include uplink transmissions from the UEs 115 to the base stations 105 or downlink transmissions from the base stations 105 to the UEs 115. The control information and data may be multiplexed on the uplink or downlink channels according to various techniques. The control information and data may be multiplexed on the downlink channel using, for example, a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some examples, the control information transmitted during a transmission time interval (TTI) of the downlink channel may be distributed among different control regions (e.g., between a common control region and one or more UE-specific control regions) in a cascaded manner.

[0033] The UEs 115 may be distributed throughout the wireless communication system 100, and each UE 115 may be fixed or mobile. The UEs 115 may also be referred to as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable terminology. The UEs 115 may also be a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a personal electronic device, a handheld device, a personal computer, a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, a machine type communications (MTC) device, equipment, an automobile, etc.

[0034] In some cases, the UE 115 may also be able to communicate directly with other UEs 115 (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more of a group of UEs 115 utilizing D2D communication may be within a cell's coverage area 110. Other UEs 115 in such a group may be outside the cell's coverage area 110 or otherwise unable to receive transmissions from the base station 105. In some cases, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some cases, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, the D2D communication is performed independently of the base station 105.

[0035] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may enable automated communication between machines, i.e., machine-to-machine (M2M) communication. M2M or MTC may refer to data communication technologies that enable devices to communicate with each other or with the base station 105 without human intervention. For example, M2M or MTC may refer to communication from devices that incorporate sensors or meters to measure or capture information and relay that information to a central server or application program that can utilize the information or present the information to a human who interacts with the program or application. Some UEs 115 may be designed to collect information or enable automated operation of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, medical monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0036] The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may interface with the core network 130 through backhaul links 132 (e.g., S1, S2). The base stations 105 may communicate with each other via backhaul links 134 (e.g., X1, X2), either directly or indirectly (e.g., through the core network 130). The base stations 105 may perform radio configuration and scheduling for communication with the UEs 115 or may operate under the control of a base station controller (not shown). In some examples, the base stations 105 may be macro cells, small cells, hot spots, etc. The base stations 105 may also be referred to as eNodeBs (eNBs) 105, next generation NodeBs (gNBs) 105, etc.

[0037] In some cases, the wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. The Radio Link Control (RLC) layer may perform packet segmentation and reassembly in some cases to communicate over logical channels. The Medium Access Control (MAC) layer may perform priority handling and multiplexing of logical channels into transport channels. The MAC layer may also perform retransmissions at the MAC layer using Hybrid Automatic Repeat Request (HARQ) to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may establish, configure, and maintain an RRC connection between the UE 115 and the base station 105 or core network 130, which supports radio bearers for user plane data. In the physical layer, the transport channels may be mapped to physical channels.

[0038] The wireless communication system 100 may support operation on multiple cells or carriers, a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation. A carrier may also be referred to as a component carrier (CC), layer, channel, etc. The terms "carrier," "component carrier," and "channel" may be used interchangeably herein. A UE 115 may be configured with multiple downlink CCs and one or more uplink CCs for CA. CA may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) CCs.

[0039] In some cases, the wireless communication system 100 may utilize an enhanced component carrier (eCC). An eCC may be characterized by one or more features including a wider bandwidth, a shorter symbol duration, a shorter TTI, and a modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC may also be configured for use in unlicensed or shared spectrum (where more than one operator is authorized to use the spectrum). An eCC characterized by a wide bandwidth may include one or more segments that may be utilized by UEs 115 that are not capable of monitoring the full bandwidth or that choose to use limited bandwidth (e.g., to conserve power).

[0040] In some cases, an eCC may use a different symbol duration than other CCs, which may include the use of a shortened symbol duration compared to the symbol duration of other CCs. The shorter symbol duration may be associated with an increased subcarrier spacing. A TTI in an eCC may include one or more symbols. In some cases, the TTI duration (i.e., the number of symbols in a TTI) may be variable. In some instances, an eCC may use a different symbol duration than other CCs, which may include the use of a shortened symbol duration compared to the symbol duration of other CCs. The shorter symbol duration is associated with an increased subcarrier spacing. A device, such as a UE 115 or a base station 105, that utilizes an eCC may transmit a wideband signal (e.g., 20, 40, 60, 80 MHz) at a reduced symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may include one or more symbols. In some cases, the TTI duration (i.e., the number of symbols in a TTI) may be variable.

[0041] Shared radio frequency spectrum bands may be utilized in NR shared spectrum systems. For example, NR shared spectrum may utilize any combination of licensed spectrum, shared spectrum, and unlicensed spectrum, among others. Flexibility in eCC symbol duration and subcarrier spacing may enable the use of eCC across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and spectral efficiency, particularly through dynamic vertical (e.g., across frequency) and horizontal (e.g., across time) sharing of resources.

[0042] In some cases, the wireless system 100 may use both licensed and unlicensed radio frequency spectrum bands. For example, the wireless system 100 may utilize LTE License Assisted Access (LTE-LAA) or LTE Unlicensed (LTE U) radio access technology or NR technology in an unlicensed band, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, the wireless devices, such as the base station 105 and the UE 115, may utilize a Listen Before Talk (LBT) procedure to ensure that the channel is clear before transmitting data. In some cases, the operation in the unlicensed spectrum may be based on a CA configuration in conjunction with a CC operating in the licensed band. The operation in the unlicensed spectrum may include downlink transmission, uplink transmission, or both. Duplexing in the unlicensed spectrum may be based on FDD, TDD, or a combination of both.

[0043] The wireless communication system 100 can also operate in the Ultra-High Frequency (UHF) region using a frequency band from 300 MHz to 3 GHz. This region is sometimes referred to as the decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter in length. UHF waves may propagate primarily by line of sight and may be blocked by buildings and environmental features. However, the waves may penetrate walls sufficiently to provide service to UEs 115 located indoors. Transmission of UHF waves is characterized by smaller antennas and shorter distances (e.g., less than 100 km) compared to transmissions using lower frequencies (and longer waves) in the High Frequency (HF) or Very High Frequency (VHF) portions of the spectrum. The wireless communication system 100 can also operate in the Super High Frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as the centimeter band. In some cases, the wireless communication system 100 may also utilize the Extremely High Frequency (EHF) portion of the spectrum (e.g., 25 GHz to 300 GHz), also known as the millimeter band. Systems using this region are sometimes referred to as millimeter wave (mmW) systems. Thus, EHF antennas may be smaller and more closely spaced than UHF antennas. In some cases, this may facilitate the use of antenna arrays (e.g., for directional beamforming) in the UE 115. However, EHF transmissions may suffer from greater atmospheric attenuation and shorter distances than UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions.

[0044] The wireless communication system 100 may support mmW communication between the UE 115 and the base station 105. Devices operating in the mmW, SHF or EHF bands may have multiple antennas to enable beamforming. That is, the base station 105 may use multiple antennas or an antenna array to perform beamforming operations for directional communication with the UE 115. Beamforming (sometimes called spatial filtering or directional transmission) is a signal processing technique that may be used in a transmitter (e.g., base station 105) to shape and / or steer an overall antenna beam in the direction of a target receiver (e.g., UE 115). This may be achieved by combining elements in an antenna array such that transmitted signals at certain angles experience constructive interference while transmitted signals at other angles experience destructive interference. For example, the base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 may use for beamforming in its communication with the UE 115. A signal may be transmitted multiple times in different directions (e.g., each transmission may be beamformed differently). A mmW receiver (e.g., UE 115) may try multiple beams (e.g., antenna sub-arrays) while receiving a SS. A multiple-input multiple-output (MIMO) wireless system uses a transmission scheme between a transmitter (e.g., base station 105) and a receiver (e.g., UE 115), both of which are equipped with multiple antennas.

[0045] In some cases, antennas of the base station 105 or UE 115 may be located in one or more antenna arrays that may support beamforming or MIMO operation. One or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some cases, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115.

[0046] A MIMO wireless system uses a transmission scheme between a transmitter (e.g., base station 105) and a receiver (e.g., UE 115), both of which are equipped with multiple antennas. Some parts of the wireless communication system 100 may use beamforming. For example, the base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 may use for beamforming in its communication with the UE 115. A signal may be transmitted multiple times in different directions (e.g., each transmission may be beamformed differently). A mmW receiver (e.g., UE 115) may try multiple beams (e.g., antenna subarrays) while receiving a SS (e.g., or other reference signal such as CSI-RS). Each of these beams may be referred to as a receive beam in aspects of the present disclosure.

[0047] In some cases, antennas of the base station 105 or UE 115 may be located in one or more antenna arrays that may support beamforming or MIMO operation. One or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some cases, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115.

[0048] Synchronization (e.g., cell acquisition) may be performed using an SS or channel transmitted by a synchronization source (e.g., base station 105). The base station may transmit an SS block including a discovery reference signal. The SS block may include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), or a physical broadcast channel (PBCH). A UE 115 attempting to access a wireless network may perform an initial cell search by detecting a PSS from the base station 105. The PSS may enable synchronization of symbol timing and may indicate a physical layer identity value. The PSS may be utilized to acquire timing and frequency, as well as a physical layer identity. The UE 115 may then receive the SSS. The SSS may enable radio frame synchronization and may provide a cell group identity value that may be combined with the physical layer identity to form a physical cell identity (PCID) that identifies the cell. The SSS may also enable detection of a duplex mode and a cyclic prefix (CP) length. The SSS may be used to acquire other system information (e.g., a subframe index). The PBCH may be used to acquire additional system information required for acquisition (eg, bandwidth, frame index).

[0049] In some cases, the SS blocks may be transmitted in a beamformed manner. Since the base station does not know the location of the device attempting to synchronize with the cell, the SS blocks may be transmitted continuously in a beam-sweeping manner, as described further below. In aspects of the present disclosure, the decoded waveform of the SS blocks may be used to effectively act as a reference signal to indicate the quality of a given beam pair link. Thus, the UE 115 may receive the beamformed SS blocks and report information based on measurements of the received SS blocks against the decoded waveform to the base station 105. The base station 105 may use the reported information for various purposes (e.g., scheduling, transmit power control). Various configurations for reporting information (e.g., which metrics to report, which beams to measure, measurement periodicity, reporting periodicity) are contemplated herein.

[0050] 2 illustrates an example of a wireless communication system 200 supporting beam management using a SS over channel feedback framework in accordance with various aspects of the present disclosure. The wireless communication system 200 includes a base station 105-a and a UE 115-a, each of which may be an example of a corresponding device described with reference to FIG.

[0051] The wireless communication system 200 may operate within a frequency range associated with beamformed transmissions between the base station 105-a and the UE 115-a. For example, the wireless communication system 200 may operate using the mmW frequency range. As a result, signal processing techniques such as beamforming may be used to coherently combine energy to overcome path loss.

[0052] As an example, the base station 105-a may include multiple antennas. In some cases, each antenna may transmit a phase-shifted version of a signal such that the phase-shifted versions interfere constructively in some regions and destructively in other regions. For example, weights may be applied to the various phase-shifted versions to steer the transmission in a desired direction. Such techniques (or similar techniques) may serve to increase the coverage area 110-a of the base station 105-a or otherwise benefit the wireless communication system 200.

[0053] The transmit beams 205-a and 205-b represent examples of beams over which information may be transmitted. Thus, each transmit beam 205 may be directed from the base station 105-a to a different region of the coverage area 110-a, and in some cases, two or more beams 205 may overlap. The transmit beams 205-a and 205-b may be transmitted simultaneously or at different times. In either case, the UE 115-a may receive one or more transmit beams 205 via respective receive beams 210-a, 210-b.

[0054] In one example, the UE 115-a may form one or more receive beams 210-a, 210-b. Like the base station 105-a, the UE 115-a may include multiple antennas. The receive beams 210-a, 210-b may each receive one of the transmit beams 205-a and 205-b (e.g., the UE 115-a may be positioned in the wireless communication system 200 such that the UE 115-a receives both beamformed transmit beams 205). Such a scheme may be referred to as a receive diversity scheme. In some cases, the receive beam 210 may receive a single transmit beam 205-a (e.g., the receive beam 210-a may receive the transmit beam 205-a with various path losses and multipath effects included). That is, each antenna of the UE 115-a may receive the transmit beam 205-a experiencing different path losses or phase shifts (e.g., different phase shifts may result from different path lengths between the base station 105-a and the respective antennas of the UE 115-a) to appropriately combine the received signals represented by the receive beam 210. The transmit beam 205 and the corresponding receive beam 210 may be referred to as a beam pair link in some cases. Various methods for identifying a desired beam pair link are considered within the scope of this disclosure. For example, in some cases, the base station 105-a may repeatedly transmit on multiple transmit beams 205 (e.g., in all directions) and the UE 115-a may report the strongest receive beam 205 (e.g., without necessarily trying multiple receive beams 210). Additionally or alternatively, the base station 105-a may transmit multiple transmit beams 205 over a small angular region (e.g., to help the UE 115-a fine-tune the selected transmit beam 205). Further, in some cases, the base station 105-a may repeat transmission of a single transmit beam (e.g., transmit beam 205-a) multiple times (e.g., to allow the UE 115-a to compare multiple receive beams 210).

[0055] In some examples, the transmit beams 205 may carry CSI-RS and / or SS. The base station 105-a may transmit to the UE 115-a using multiple transmit beams 205, and the UE 115-a may use different antenna subarrays to generate various receive beams 210. For example, during a cell acquisition procedure, the UE 115-a may receive one or more transmit beams 205 using different receive beams 210 and may determine the pairing of the transmit beam 205 and receive beam 210 that has the strongest signal (i.e., has the highest measured signal strength or highest signal-to-noise ratio (SNR)). Throughout the communication, the UE 115-a may re-evaluate the pairing of the transmit beam 205 and receive beam 210 based on various SS blocks and CSI-RS transmissions (which may be part of beam management, for example).

[0056] As described herein, the waveforms associated with a virtual antenna port and a given SS block may be referred to as resources (e.g., such that each SS block may form an individual resource). A similar definition may apply to CSI-RS (e.g., the waveforms associated with a resource may span a single or several symbols). Thus, measurements made by the UE 115-a (e.g., Reference Signal Received Power (RSRP), Channel Quality Indicator (CQI)) may be made on resources. In various examples, the base station 105-a may transmit waveforms on several resources and request that the UE 115-a compare their performance with respect to one or more specified metrics (e.g., RSRP, SNR, CQI). The collection of resources for comparison may be referred to as a resource set. In some cases, the UE 115-a may be requested to report one or more metrics for each resource or for a number of requested resources (e.g., N best resources) along with their CSI-RS resource indicator (CRI). A set of transmit beams 205 (e.g., including SS blocks) that covers all spatially relevant directions of a cell may be referred to herein as an SS burst. An SS burst may have, for example, 128 SS blocks, and in some cases, an SS burst may be partitioned into a subset of SS blocks.

[0057] In some instances, joint reporting for SS blocks and CSI-RS may be achieved by examining the similarity between the SS blocks and the CSI-RS. For example, after the UE 115-a decodes the content of the SS block, the decoded waveform can be viewed as a reference signal (e.g., similar to the CSI-RS waveform). In either case, the UE 115-a receives known waveforms over time from a set of antenna ports of the base station 105 associated with a given transmit beam 205. Thus, the base station 105-a may, for example, ask the UE 115-a about the SS block associated with the transmit beam 205 that is most suitable for communication with the UE 115-a. The UE 115-a may, for example, report the RSRP and CRI that identify the SS block associated with the best transmit beam 205.

[0058] Within the CSI-RS framework, the base station 105-a may provide the UE 115-a with details of reporting procedures, etc. for each of a number of resource sets. For example, the details may specify what the UE 115-a measures (e.g., resources associated with a resource set) when the UE 115-a reports (e.g., periodically, semi-permanently, aperiodically based on a trigger, autonomously) and the metrics (e.g., CQI, RSRP, SNR) that the UE 115-a should report. The resource set may be configured to include resources of SS bursts, and the base station 105-a may similarly configure the details of the UE 115-a reporting procedures. For example, the base station 105-a may request the UE 115-a to report periodically or based on a trigger (e.g., aperiodically). The trigger may be based on certain downlink control information (DCI) or certain conditions (e.g., when the metrics of the resource become better than the metrics of the previously identified best resource after considering some hysteresis).

[0059] 3 illustrates an example of a resource set configuration 300 supporting beam management using a SS over channel feedback framework in accordance with various aspects of the disclosure. In some examples, the resource set configuration 300 may be transmitted from the base station 105 to the UE 115 (e.g., via RRC signaling, control channel). In some cases, various specifications of resources and resource sets described below may remain partially or completely predetermined (e.g., programmed, hard-coded into the device when provisioning it on the network).

[0060] For example, the base station 105 may configure the UE 115 for a full CSI-RS procedure immediately after the UE 115 accesses the system (e.g., performs an attachment procedure on a cell of the system). Similarly, the base station 105 may configure the UE 115 to measure and report information about beams (e.g., transmit beams and / or receive beams) associated with one or more SS blocks according to aspects of the present disclosure. That is, after system access, the base station 105 may provide details of what to measure and how to report regarding the SS blocks. For example, the resource set configuration 300 may include a resource identification field 305. The resource identification field 305 may define the resources (e.g., SS bursts, SS blocks, CSI-RS) to be measured by the UE 115. For example, the base station 105 may indicate in the resource identification field 305 which SS blocks of an SS burst are within the resource set. This information may assist the UE 115 in finding a suitable receive antenna array and receive pattern to optimally detect the SS block. Additionally or alternatively, the base station 105 may indicate in the resource identification field 305 the time when the SS block is transmitted and the duration of the SS burst. Such information may be useful, for example, when the UE 115 is required to monitor SS blocks of other neighboring base stations 105 for unsynchronized cells. Finally, in some cases, the resource identification field 305 may carry information related to a codebook of precoding matrices to determine how to linearly combine antenna ports to achieve single or multi-layer transmission of a resource set. In some cases, the number of layers may be limited by the capabilities of the UE 115 and the number of virtual antenna ports involved in transmitting the SS block.

[0061] The resource set configuration 300 may include a metric identification field 310 and / or a reporting configuration field 315. For example, the metric identification field 310 may specify which metrics the UE 115 measures in association with transmitted SS blocks. The reporting configuration field 315 may specify how the UE 115 reports the measured metrics (e.g., periodically, semi-persistently, aperiodically according to a trigger, autonomously). The resource set configuration 300 may additionally include other fields (e.g., such that the illustrated fields are included for illustrative purposes only). For example, the resource set configuration 300 may include an indicator of which SS blocks are associated with quasi-colocated (QCL) beams (e.g., beams pointing in a similar direction). Additionally, although shown separately for purposes of illustration, information associated with the various fields described above may be combined in some cases (e.g., such that a given metric may always be associated with a periodic transmission).

[0062] In some cases, the base station 105 may configure the UE 115 for multiple resource set configurations 300 for parallel operation. For example, each resource set configuration 300 may indicate different resources, and different UEs 115 or groups of UEs 115 may be configured differently (e.g., based on location within a coverage area).

[0063] Alternative methods of defining (e.g., and configuring) resources and resource sets are also contemplated. For example, in some cases, the SS blocks of an SS burst may be partitioned into groups (e.g., SS burst subsets) and the UE 115 may be required to identify one or more groups of resources within the SS burst. In some examples, the groups may be communicated to the UE 115 at the time of configuration (e.g., after system access) or may be defined (e.g., by some specification). For example, such an approach may be useful when there are a large number of SS blocks and the base station 105 does not want to wait until the entire SS burst is finished before receiving a report. Thus, such an approach may be associated with lower latency.

[0064] Also considered are approaches where all SS blocks of an SS burst form a single resource with multiple antenna ports. In some cases, a codebook of precoding matrices may be used such that only one or two antenna ports may be combined to form a layer. Thus, if RSRP is defined as a performance metric (e.g., in the metric identification field 310), the UE 115 may automatically search for the SS block with the highest RSRP and report it (e.g., based on the reporting configuration field 315) using an associated precoding matrix indicator. This may be used, for example, when the base station 105 transmits multiple SS blocks simultaneously (e.g., in the same slot) using multiple parallel transmit beams. The UE 115 may report a precoding matrix indicator (PMI) or other index to a codebook that identifies the antenna port with the highest performance metric. The UE 115 may additionally report a performance metric. Thus, the UE 115 may report the RSRP / CQI along with the PMI (e.g., in addition to or instead of the CRI).

[0065] According to various techniques described herein, the SS may assist in beam management through the use of a channel feedback framework. The base station 105 may periodically transmit multiple SS blocks that are beamformed in multiple spatial directions. In some cases, the base station 105 and / or predefined information may define which portions of the transmitted SS blocks constitute resources or resource sets. The base station 105 may configure the UE 115 for measurements and for reporting using a CSI-RS framework that applies to the defined resources and resource sets. The UE 115 may report information about the beamformed SS blocks according to the configuration. In some examples, the base station 105 configures the UE 115 to report RSRP or CQI for the best resource in conjunction with the CRI. In some cases, the base station configures the UE 115 to report at regular intervals or upon the occurrence of some trigger.

[0066] 4 illustrates an example of a process flow 400 for supporting beam management using a SS over channel feedback framework in accordance with various aspects of the present disclosure. The process flow 400 includes a UE 115-b and a base station 105-b, each of which may be an example of a corresponding device described above with reference to FIGS. 1 and 2.

[0067] At 405, the base station 105-b and the UE 115-b may establish a communication link (e.g., which may be an example of the communication link 125 described with reference to FIG. 1). For example, the communication link at 405 may support beamformed communication.

[0068] At 410, the base station 105-b may optionally transmit a configuration message to the UE 115-b. The configuration message may include, for example, one or more fields of the resource set configuration 300 described with reference to FIG. 3. Thus, at 410, the base station 105-b may configure the UE 115-b according to the channel state information (CSI) framework, the first feedback resource set, and the reporting configuration.

[0069] At 415, the UE 115-b may identify a first feedback resource set and reporting configuration indicating a plurality of SS blocks of the SS burst transmitted by the base station 105-b using the first set of transmit beams. In some cases, the configuration identification information may be based on the configuration message received at 410. That is, identifying the first feedback resource set and reporting configuration may include receiving the first feedback resource set and reporting configuration from the base station 105-b. In an example, the plurality of SS blocks may include a subset of the SS blocks of the SS burst. In some cases, the first feedback resource set and reporting configuration includes a spatial QCL indicator for at least one of the plurality of SS blocks, an indicator of resources for the plurality of SS blocks, an indicator of a duration of the SS burst, an indicator of antenna ports associated with the plurality of SS blocks, an indicator of a number of SS blocks of the SS burst, an indicator of a channel metric to report for the plurality of SS blocks, or a combination thereof.

[0070] At 420, the UE 115-b may receive an SS burst from the base station 105-b. In some cases, the UE 115-b may identify waveforms for multiple SS blocks to perform a first channel measurement based at least on decoding at least one SS block of the SS burst received at 420.

[0071] At 425, the UE 115-b may perform a first channel measurement for the multiple SS blocks. In an aspect, the first channel measurement may be based on the configuration identified at 415.

[0072] At 430, the UE 115-b may report a first resource indicator for at least one of the plurality of SS blocks to the base station 105-b based on the first channel measurement. In some cases, the base station 105-b may determine a characteristic of a transmit beam for a transmission (e.g., a data transmission, a control transmission, a future transmission, a current transmission) to the UE 115-b based on the first resource indicator. In some examples, the reporting includes reporting a channel metric associated with at least one of the plurality of SS blocks. In some cases, the reporting includes an indicator of an antenna port for at least one of the plurality of SS blocks. In aspects, the reporting may be performed periodically, semi-persistently, or aperiodically as identified by the first feedback reporting configuration. In some cases, the aperiodically reporting may be performed based on a trigger, the trigger including receiving a report indicator in a DCI message or identifying a trigger event based on the channel measurement performed at 425.

[0073] At 435, the UE 115-b may optionally obtain a second feedback resource set and reporting configuration that identifies a set of resources associated with the CSI-RS to be transmitted by the base station 105-b using a second set of transmit beams (which may be the same or different as the transmit beams used to transmit the SS burst at 420). In some cases, the second configuration may be obtained simultaneously and / or in a similar manner as the first configuration (which may be obtained, for example, in the configuration message at 410 or a similar message).

[0074] At 440, the UE 115-b may perform second channel measurements for the CSI-RS based on the second configuration.

[0075] At 445, the UE 115-b may report at least one channel metric for at least one of the set of resources associated with the CSI-RS and a second resource indicator for the at least one of the set of resources to the base station 105-b according to a second reporting configuration based on the second channel measurements performed at 440.

[0098] FIG. 8 illustrates a diagram of a system 800 including a device 805 supporting beam management using a SS over channel feedback framework according to an aspect of the disclosure. The device 805 may be or include an example of a component of a wireless device 505, a wireless device 605, or a UE 115, for example, as described above with reference to FIG. 5 and FIG. 6.

[0142] It should be noted that the methods described above describe possible implementations, and that the operations and steps may be rearranged or otherwise modified, and other implementations are possible. Furthermore, aspects from two or more of the methods may be combined.

[0143] The techniques described herein may be used for various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" are often used interchangeably. A CDMA system may implement a radio technology, such as CDMA2000, Universal Terrestrial Radio Access (UTRA), and the like. CDMA2000 covers IS-2000, IS-95, and IS-856 standards. IS-2000 releases are sometimes commonly referred to as CDMA2000 1X, 1X, and the like. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO, High Rate Packet Data (HRPD), and the like. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. A TDMA system may implement a radio technology such as Global System for Mobile communications (GSM).

[0144] An OFDMA system may implement a radio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are releases of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, NR, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the systems and radio technologies mentioned above as well as other systems and radio technologies. Although aspects of LTE or NR systems may be described as examples, and LTE or NR terminology may be used throughout much of the description, the techniques described herein are applicable to other than LTE or NR applications.

[0145] In LTE / LTE-A networks, including such networks described herein, the term eNB may be used generally to refer to a base station. One or more wireless communications systems described herein may include heterogeneous LTE / LTE-A or NR networks in which different types of eNBs provide coverage for various geographic regions. For example, each eNB, subsequent gNB, or base station may provide communication coverage for a macro cell, a small cell, or other types of cell. The term "cell" may be used to refer to a base station, a carrier or CC associated with a base station, or a coverage area (e.g., sector, etc.) of a carrier or base station, depending on the context.

[0146] A base station may include or be referred to by one skilled in the art as a base transceiver station, radio base station, access point, radio transceiver, NodeB, eNB, gNB, Home NodeB, Home eNodeB, or some other suitable terminology. A geographic coverage area for a base station may be divided into sectors making up only a portion of the coverage area. One or more wireless communication systems described herein may include different types of base stations (e.g., macro base stations or small cell base stations). A UE described herein may be capable of communicating with various types of base stations and network equipment, including macro eNBs, small cell eNBs, gNBs, relay base stations, etc. Geographic coverage areas for different technologies may overlap.

[0147] A macro cell generally covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs subscribing to the network provider's service. A small cell is a low-power base station that may operate as a macro cell in the same or a different (e.g., licensed, unlicensed) frequency band as a macro cell, in comparison to a macro cell. A small cell may include a pico cell, a femto cell, and a micro cell, according to various examples. A pico cell, for example, may cover a small geographic area and may allow unrestricted access by UEs subscribing to the network provider's service. A femto cell may also cover a small geographic area (e.g., a home) and may allow restricted access by UEs having an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG), UEs for users in the home, etc.). An eNB for a macro cell may be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB may support one or multiple (eg, two, three, four, etc.) cells (eg, CCs).

[0148] One or more wireless communications systems described herein may support synchronous or asynchronous operation. For synchronous operation, base stations may have similar frame timing and transmissions from different base stations may be approximately aligned in time. For asynchronous operation, base stations may have different frame timing and transmissions from different base stations may not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0149] A downlink transmission as described herein may be referred to as a forward link transmission, and an uplink transmission may be referred to as a reverse link transmission. Each communication link as described herein, including, for example, the wireless communication systems 100 and 200 of FIGs. 1 and 2, may include one or more carriers, and each carrier may be a signal composed of multiple subcarriers (e.g., waveform signals at different frequencies).

[0150] The description set forth herein with respect to the accompanying drawings describes exemplary configurations and does not necessarily represent every example that may be implemented or fall within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration" and does not mean "preferred" or "advantageous over other examples." The detailed description includes specific details to enable an understanding of the described techniques. However, these techniques may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.

[0151] In the accompanying drawings, similar components or features may have the same reference label. Furthermore, various components of the same type may be distinguished by following the reference label with a dash and a second label that distinguishes the similar components. If only a first reference label is used herein, the description is applicable to any of the similar components having the same first reference label, regardless of the second reference label.

[0152] The information and signals described herein may be represented using any of a wide variety of technologies and techniques. For example, the data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0153] The various example blocks and modules described in connection with the disclosure herein may be implemented or performed using a general purpose processor, a DSP, an ASIC, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but alternatively, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0154] The functions described herein may be implemented as hardware, software executed by a processor, firmware, or any combination thereof. When implemented in software executed by a processor, the functions may be stored on or transmitted through a computer-readable medium as one or more instructions or codes. Other examples and implementations fall within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described above may be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination thereof. Features implementing the functions may also be physically located in various locations, including being distributed such that portions of the functions are implemented in different physical locations. Also, as used herein, including within the claims, "or" used in a list of items (e.g., a list of items ending with a phrase such as "at least one of" or "one or more of") indicates an inclusive list, such as, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, the phrase "based on" as used herein should not be construed as referring to a closed set of conditions. For example, an example step described as "based on condition A" may be based on both condition A and condition B without departing from the scope of the present disclosure. As used herein, the phrase "based on" should be interpreted similarly to the phrase "based at least in part on."

[0155] Computer-readable media includes both non-transitory computer storage media and communication media, including any medium that facilitates transfer of a computer program from one place to another. Non-transitory storage media may be any available medium that can be accessed by a general purpose or special purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, Electrically Erasable Programmable Read-Only Memory (EEPROM), Compact Disk (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code means in the form of instructions or data structures and that can be accessed by a general purpose or special purpose computer or a general purpose or special purpose processor. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of media. As used herein, disk and disc include CD, laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Blu-ray disc, where disks typically reproduce data magnetically and discs reproduce data optically using lasers. Combinations of the above are also included within the scope of computer readable media.

[0156] The description herein is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to the present disclosure will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of the present disclosure.
