[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This patent application claims priority to commonly assigned PCT patent application No. PCT / CN2021 / 071662, entitled "TECHNIQUES FOR DIRECTIONAL SIGNAL STRENGTH INDICATION AND BEAM-SPECIFIC MEASUREMENT THRESHOLD," filed on January 14, 2021. The disclosure of the prior application is considered part of, and incorporated by reference into, this patent application.

[0002] Aspects of the present disclosure relate generally to wireless communication and to techniques and apparatus for directional signal strength indication and beam-specific measurement thresholds. [Background technology]

[0003]

[0003] Wireless communication systems have been widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0004] A wireless network may include several base stations (BSs) that can support communication for several user equipments (UEs). The UEs may communicate with the BSs via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receive point (TRP), a new radio (NR) BS, a 5G Node B, etc.

[0005]

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that allows different user equipment to communicate on a city, national, regional, or even global scale. NR, sometimes referred to as 5G, is a set of extensions to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, lowering costs, improving services, utilizing new spectrum, and better integrating with other open standards using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further developments in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

The wireless network 100 may include several base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit reception point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to the coverage area of ​​a BS and / or a BS subsystem serving this coverage area, depending on the context in which the term is used.

[0118]

[0127] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs that have an association with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. 1, BS 110a may be a macro BS for a macro cell 102a, BS 110b may be a pico BS for a pico cell 102b, and BS 110c may be a femto BS for a femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” may be used interchangeably herein.

[0119]

[0128] In some aspects, the cells may not necessarily be fixed and the geographic area of ​​the cells may move according to the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in wireless network 100 through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0120]

[0129] The wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in FIG. 1, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to enable communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, etc.

[0121]

[0130] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5-40 watts), while a pico BS, femto BS, and relay BS may have a lower transmit power level (e.g., 0.1-2 watts).

[0122]

[0131] A network controller 130 may couple to a set of BSs and provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other, e.g., directly or indirectly via a wireless or wireline backhaul.

[0123]

[0132] The UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be fixed or mobile. A UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate over a wireless or wired medium.

[0124]

[0133] Some UEs may be considered as machine type communication (MTC) UEs or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and eMTC UEs include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and / or a location tag that may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). The UE 120 may be included in a housing that stores components of the UE 120, such as a processor component and / or a memory component. In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0125]

[0134] Generally, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. The RAT may also be referred to as a radio technology, an air interface, etc. The frequencies may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0126]

[0135] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using a base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) protocols (which may include, e.g., vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, the UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0127]

[0136] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various classes, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1), which may range from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2), which may range from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. FR1 is often referred to as the "sub-6 GHz" band, although a portion of FR1 is greater than 6 GHz. Similarly, FR2 is often referred to as "millimeter wave" even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the "millimeter wave" band by the International Telecommunications Union (ITU). Thus, unless otherwise specified, it should be understood that terms such as "sub-6 GHz," as used herein, may broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specified, it should be understood that terms such as "millimeter wave," as used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included within FR1 and FR2 may be altered, and that the techniques described herein are applicable to those altered frequency ranges.

[0128]

[0137] As noted above, Figure 1 is provided as an example. Other examples may differ from those described with respect to Figure 1.

[0129]

[0138] 2 is a diagram illustrating an example base station 110 200 in communication with a UE 120 in a wireless network 100 in accordance with the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0130]

[0139] At the base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCSs) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the selected MCS(es) for that UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, and / or higher layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0131]

[0140] At the UE 120, antennas 252a-252r may receive downlink signals from the base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control and system information to a controller / processor 280. The term “controller / processor” may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0132]

[0141] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0133]

[0142] An antenna (e.g., antennas 234a-t and / or antennas 252a-r) may include or be contained within one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include a set of coplanar antenna elements and / or a set of non-coplanar antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include antenna elements in a single housing and / or antenna elements in multiple housings. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components of FIG. 2.

[0134]

[0143] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a-254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, a modulator and / or demodulator 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (e.g., a controller / processor 280) and a memory 282 to implement aspects of any of the methods described herein.

[0135]

[0144] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate to the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communication. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of the antenna(s) 234, the modulator and / or demodulator 232, the MIMO detector 236, the receive processor 238, the transmit processor 220, and / or the TX MIMO processor 230. The transceiver may be used by a processor (e.g., a controller / processor 240) and a memory 242 to implement aspects of any of the methods described herein.

[0136]

[0145] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component(s) of FIG. 2 may implement one or more techniques related to directional signal strength indication and beam-specific measurement thresholds as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component(s) of FIG. 2 may implement or direct the operation of, for example, process 700 of FIG. 7, process 800 of FIG. 8, and / or other processes described herein. The memories 242 and 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly or after compiling, translating, and / or interpreting) by one or more processors of the base station 110 and / or the UE 120, may cause the one or more processors, the UE 120, and / or the base station 110 to perform or direct operations of, for example, process 700 of FIG. 7, process 800 of FIG. 8, and / or other processes described herein. In some aspects, executing the instructions may include running the instructions, translating the instructions, compiling the instructions, and / or interpreting the instructions.

[0137]

[0146] In some aspects, the UE includes means for receiving configuration information for RSSI measurement, the configuration information indicating a TCI state configuration for RSSI measurement, means for performing RSSI measurement based at least in part on the TCI state configuration, and / or means for transmitting a measurement report of the RSSI measurement. The means for the UE to perform operations described herein may include, for example, one or more of the antenna 252, the demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the modulator 254, the controller / processor 280, or the memory 282.

[0138]

[0147] In some aspects, the base station includes means for transmitting configuration information for RSSI measurement, the configuration information indicating the TCI state configuration for RSSI measurement, and / or means for receiving measurement reports and the TCI state configuration for RSSI measurement, to the UE. The means for the base station to perform the operations described herein may include, for example, one or more of the transmit processor 220, the TX MIMO processor 230, the modulator 232, the antenna 234, the demodulator 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0139]

[0148] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2.

[0140]

[0149] The UE may perform cell selection or reselection procedures to identify a suitable cell for connectivity, mobility, etc. Cell selection and reselection may utilize radio resource management (RRM) measurements. The RRM measurements may enable appropriate cell selection / reselection for some radio access technologies (RATs), such as NR Unlicensed (NR-U). The RRM measurements may be based at least in part on reception of discovery reference signals (DRS), including synchronization signal blocks (SSBs) and / or channel state information reference signals (CSI-RS). The UE may perform measurements based at least in part on the DRS and may transmit measurement reports of the measurements. The measurement reports may include, for example, reference signal received power (RSRP) and / or reference signal received quality (RSRQ).

[0141]

[0150] Due to dynamically changing channel conditions in the unlicensed spectrum, some RRM measurement reports may not be sufficient to reflect loading conditions, interference outside of downlink bursts, and potential hidden nodes in the unlicensed channel. To mitigate this issue, NR-U UEs may be configured to report average received signal strength indicator (RSSI) and channel occupancy as part of the RRM measurements. The average RSSI may provide an estimate of the loading conditions and may provide information about the overall interference on the NR-U cell. Channel occupancy may be defined as the percentage of time when the channel is sensed to be busy (e.g., when the measured RSSI samples are above a predefined threshold). In some deployments, such as sub-7 GHz deployments, omnidirectional antennas are used at the UE, so RSSI calculations are straightforward and channel occupancy is not particularly direction-dependent. However, in deployments utilizing beamforming, such as mmWave, multiple beams may be used at the UE, and different receive beams may have different RSSI values ​​and therefore different channel occupancies. An omnidirectional RSSI measurement configuration may not be able to take into account RSSI values ​​and channel occupancy across different receive beams, which reduces the effectiveness of the RSSI measurement and degrades network performance.

[0142]

[0151] Some techniques and apparatus described herein provide an extension of RSSI measurements to a per-beam level. For example, a base station may configure a UE to perform RSSI measurements for one or more receive beams based at least in part on one or more transmission configuration indication (TCI) states, described in more detail elsewhere herein. The UE may perform RSSI measurements based at least in part on one or more TCI states and may transmit a measurement report to the BS. The measurement report may indicate per-beam RSSI information, as described in more detail elsewhere herein. In some aspects, the BS may refrain from transmitting one or more signals (e.g., any signals, any signals directed to the UE 120, etc.) during a time interval associated with the RSSI measurement and / or using the TCI state indicated by the configuration information. In this manner, beam-based RSSI measurements and reports provide information regarding RSSI values ​​and channel occupancy across different receive beams, which improves the effectiveness of RSSI measurements in beamforming-based networks and improves network performance.

[0143]

[0152] 3 is a diagram illustrating an example 300 of per-beam RSSI measurement and reporting in accordance with the present disclosure. As shown, FIG. 3 includes a UE 120 and a BS 110. In some aspects, the UE 120 may include a UE capable of beamformed communications, such as a UE capable of using an mmWave RAT, or the like.

[0144]

[0153] As indicated by reference numeral 310, the BS 110 may transmit configuration information for RSSI measurements to the UE 120. As indicated, the configuration information may indicate a TCI state configuration (e.g., one or more TCI states for RSSI measurements to be performed by the UE 120). The BS 110 may transmit the configuration information via one or more of radio resource control (RRC) signaling, medium access control (MAC) signaling, downlink control information (DCI), and the like. In general, the configuration information may directly or indirectly indicate one or more beams for performing RSSI measurements, a time interval for performing RSSI measurements using a given beam, a reporting configuration for measurement reporting, and the like. In some aspects, the configuration information may indicate a configuration for averaging of RSSI measurements, as described in more detail below. The RSSI measurement indicates the total received power from all sources, including interference and noise. The RSSI measurement using a given beam may indicate the total received power when using the given beam as a receiving beam.

[0145]

[0154] In some aspects, the configuration information may indicate one or more parameters related to the RSSI measurement. For example, the configuration information may indicate a channel occupancy threshold (e.g., an RSSI threshold used for channel occupancy assessment), a measurement duration in number of symbols (e.g., the number of consecutive symbols for which the physical layer of the UE 120 should report samples of RSSI), a reference subcarrier spacing and / or cyclic prefix to be used for the RSSI measurement, an RSSI measurement timing configuration (RMTC) center frequency (sometimes referred to as center frequency, which indicates the center frequency of the bandwidth being measured), an RMTC periodicity (e.g., indicating the periodicity for the RSSI measurement), an RMTC subframe offset (e.g., indicating the RMTC subframe offset for a given frequency), one or more parameters used to determine the measurement result parameters (e.g., this may indicate the measured RSSI result in dBm and a channel occupancy indicator, which may indicate the percentage of samples when the RSSI was above a configured channelOccupancyThreshold for the associated reporting configuration), etc.

[0146]

[0155] In some aspects, the configuration information may include a TCI state configuration. The TCI state configuration may indicate one or more TCI states and / or one or more time intervals associated with one or more TCI states. In general, the TCI state may be used to indicate a beam. For example, the beam indication may be based at least in part on the configuration of the TCI state and the downlink signaling. The TCI state may derive quasi-co-location (QCL) information from a reference signal (such as CSI-RS or SSB). The QCL information may define one or more parameters used for beam-based communication, such as one or more Doppler parameters, spatial receive filters, etc. By associating a certain downlink transmission (such as a physical downlink control channel (PDCCH) or a physical downlink shared channel (PDSCH)) with a certain TCI state, the BS 110 may inform the UE 120 to assume that the downlink transmission uses the same spatial filter as the reference signal associated with that TCI state. Thus, the UE 120 may determine a receive beam to use to receive the downlink transmission. The techniques and apparatus described herein provide for the BS 110 to configure one or more TCI states for RSSI measurements by the UE 120 such that the UE 120 performs RSSI measurements by monitoring or sampling one or more beams defined by the one or more TCI states (e.g., at one or more time intervals indicated by the configuration information).

[0147]

[0156] In some aspects, one or more of the RSSI-related parameters described above may be configured for a TCI state or a TCI state group. For example, a measurement reporting configuration may be configured for a TCI state or for a TCI state group such that different TCI states or TCI state groups may have different thresholds for channel occupancy determination or measurement reporting. As another example, RMTC, RMTC periodicity, RMTC subframe offset, and / or measurement duration may be configured for a TCI state or for a TCI state group such that different TCI states or TCI state groups may have different values ​​of such parameters. In such a case, in some aspects, the center frequency, the reference subcarrier spacing, and the cyclic prefix type (e.g., the reference cyclic prefix) may be the same across two or more TCI states or TCI state groups (e.g., all configured TCI states or TCI state groups). In some aspects, the one or more parameters used to determine the measurement result parameter (e.g., which may indicate the measured RSSI result in dBm and a channel occupancy indicator that may indicate the percentage of samples when the RSSI was above a configured channel occupancy threshold for the associated reporting configuration) may be configured for a TCI state or TCI state group such that different TCI states or TCI state groups may have different thresholds for channel occupancy or measurement reporting. Thus, the RMTC parameters may be extended to apply to beam-level RSSI.

[0148]

[0157] In some aspects, parameters related to RSSI measurements may be selected from a set of values ​​based at least in part on the RSSI measurements being configured in the TCI state configuration. As an example, the measurement duration may have a larger range of possible values ​​that may be configured than the omnidirectional RSSI measurements (e.g., 84 symbols, 98 symbols, 114 symbols, etc.), where "larger range" refers to a measurement duration that includes more symbols than the measurement duration for the omnidirectional RSSI measurements. As a second example, the reference subcarrier spacing may have a larger range of possible values ​​that may be configured than the omnidirectional RSSI measurements (e.g., 120 kHz, 240 kHz, etc.), where "larger range" refers to a reference subcarrier spacing that is wider than the subcarrier spacing for the omnidirectional RSSI measurements.

[0149]

[0158] In some aspects, the configuration information may indicate a beam sweeping configuration for RSSI measurements. "Beam sweeping" refers to communication (e.g., performing RSSI measurements) using different beams at different time intervals such that various directions are utilized over different time intervals. For a more detailed description of beam sweeping, see the description accompanying FIG. 6.

[0150]

[0159] As indicated by reference numeral 320, UE 120 may determine one or more spatial receive parameters based at least in part on the TCI state configuration. For example, if the TCI state configuration identifies a TCI state to be used for RSSI measurements at a given time, UE 120 may identify QCL information based at least in part on a reference signal identified by the TCI state. UE 120 may use the QCL information to determine a spatial receive filter for the RSSI measurements. UE 120 may set a spatial receive filter that corresponds to the TCI state indicated by BS 110.

[0151]

[0160] As indicated by reference numeral 330, UE 120 may perform an RSSI measurement based at least in part on the TCI state configuration. For example, UE 120 may apply the spatial receive filter determined with respect to reference numeral 320 (e.g., by collecting a set of measurement samples while applying the spatial receive filter and determining an RSSI measurement using the set of measurement samples) and may determine an RSSI measurement based at least in part on the spatial receive filter. In some aspects, UE 120 may perform an increased number or increased rate of measurement samples for beam-based RSSI measurements than for omnidirectional RSSI measurements. In some aspects, BS 110 may refrain from transmitting one or more signals (e.g., any signals, any signals directed to UE 120, etc.) during a time interval associated with the RSSI measurement and / or using the TCI state indicated by the configuration information.

[0152]

[0161] In some aspects, the RSSI measurement may be based at least in part on an average value. As a first example, the UE 120 may determine an average RSSI measurement if the TCI state for the RSSI measurement is the same for a duration of T milliseconds (where T is configurable, pre-configured, specified, etc.) and may not perform averaging over the TCI state. As a second example, the UE 120 may determine an average RSSI measurement if the same receive beam at the UE 120 is used for values ​​contributing to the average RSSI measurement. As a third example, the UE 120 may determine an average value if the same UE receive beam is used for values ​​contributing to the average RSSI measurement and if a difference (e.g., range of RSSI values, deviation of RSSI values, etc.) associated with the average RSSI measurement meets (e.g., is less than) a threshold, which may be configured, pre-configured, specified, etc. In the second and third examples, the UE 120 may report an RSSI beam group associated with the average RSSI measurement. In some aspects, the UE 120 may not perform averaging of RSSI measurements, even within a TCI state.

[0153]

[0162] As indicated by reference numeral 340, UE 120 may transmit a measurement report regarding RSSI measurements. For example, the measurement report may indicate one or more measurements determined based at least in part on configuration information. In some aspects, the measurement report may include one or more values ​​based at least in part on measurement result parameters, described in more detail with respect to reference numeral 310 above. As further indicated, in some aspects, the measurement report may indicate an average value based at least in part on the TCI state configuration. For example, if UE 120 determined an average value, as described with respect to reference numeral 330 above, UE 120 may report information indicative of and / or related to the average value, such as RSSI beam group, TCI information, etc. In some aspects, BS 110 may perform one or more actions based at least in part on the measurement report, such as triggering cell selection or reselection, mobility actions, etc.

[0154]

[0163] As noted above, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3.

[0155]

[0164] FIG. 4 illustrates an example 400 of per-beam RSSI measurement and reporting according to the present disclosure. The example 400 includes a serving BS 110, an interfering BS 110, and a UE 120. As indicated by reference numeral 410, the serving BS 110 may transmit configuration information to the UE 120, such as the configuration information indicated by reference numeral 310 in FIG. 3. As indicated by reference numeral 420, the UE 120 may perform RSSI measurements using multiple beams, such as based at least in part on the TCI state configuration provided by the configuration information. For example, the UE 120 may perform RSSI measurements using beams 1, 2, 3, and 4. As indicated by reference numeral 430, the UE 120 may transmit a measurement report based at least in part on the RSSI measurements. The measurement report may indicate measurements determined for beams 1, 2, 3, and 4, as indicated by reference numeral 440. Thus, the serving BS 110 can identify particular beams, directions, etc. (e.g., beams 3 and 4 in example 400) that are associated with higher interference and take appropriate action based at least in part on the particular beams, directions, etc.

[0156]

[0165] As noted above, Figure 4 is provided as an example. Other examples may differ from those described with respect to Figure 4.

[0157]

[0166] 5 is a diagram illustrating an example 500 of per-beam RSSI measurement and reporting in accordance with the present disclosure. As shown, the example 500 includes a serving BS 110 and a UE 120. As indicated by reference numeral 510, the BS 110 may configure the UE 120 (e.g., via configuration information such as the configuration information indicated by reference numeral 310) to measure RSSI based at least in part on four TCI states, i.e., TCI states 4, 8, 12, and 16. As indicated by reference numeral 520, the UE 120 may perform RSSI measurements using beam A (e.g., for TCI states 4 and 12) and beam B (e.g., for TCI states 8 and 16) based at least in part on the four TCI states, where TCI states 4, 8, 12, and 16 correspond to beams {A, B, A, B}. If UE 120 is enabled to determine average values ​​when the same UE receiving beam is used, UE 120 may determine a first average value for the RSSI measurement corresponding to beam A and a second average value for the RSSI measurement corresponding to beam B. As indicated by reference numeral 530, UE 120 may transmit a measurement report including an indication of an RSSI beam group (e.g., beam A for TCI states 4 and 12, and beam B for TCI states 8 and 16). The RSSI beam group is a set of beams used to determine one or more RSSI measurements associated with the measurement report. Thus, UE 120 reports information indicating the beam corresponding to the RSSI measurement determined by UE 120, which enables BS 110 to take appropriate action based at least in part on the beam corresponding to the RSSI measurement.

[0158]

[0167] As noted above, Figure 5 is provided as an example. Other examples may differ from those described with respect to Figure 5.

[0159]

[0168] FIG. 6 illustrates examples 600 and 605 of per-beam RSSI measurement and reporting according to the present disclosure. Examples 600 and 605 illustrate potential beam sweeping configurations for RSSI measurement, such as may be configured with respect to the operations of FIGS. 3-5. In examples 600 and 605, a RMTC periodicity (also referred to herein as measurement periodicity or periodicity) of 40 ms is used. A UE (e.g., UE 120) may perform beam sweeping within a single RMTC periodicity in examples 600 and 605, as well as in other examples described herein (e.g., examples 300, 400, and / or 500). Additionally, radio frames #0, #1, #2, and #3 are shown, each including 10 subframes. RSSI measurements may be configured to be performed at a measurement duration, shown as "measDuration," which may be defined by a number of symbols, as described with respect to FIG. 3. In examples 600 and 605, RSSI measurements are performed for beam 1 (B#1), beam 3 (B#3), beam 4 (B#4) and beam 6 (B#6).

[0160]

[0169] In some aspects, the RSSI measurement symbols may not be consecutive for each TCI state at a given RMTC periodicity. The RSSI measurement symbols (also referred to as measurement symbols) are the symbols on which the RSSI measurements are performed. Example 600 illustrates non-consecutive RSSI measurement symbols. As shown, at a given measurement duration, RSSI measurements are performed for beam 1, beam 3, beam 4, and beam 6. In example 600, the RMTC for each of the RSSI measurements may be configured equivalently for each TCI state, except for the subframe offset. For example, the RSSI measurements may have the same RTMC and different subframe offsets. For example, the subframe offsets may be configured such that no overlap in the time domain occurs between the TCI states, as illustrated by the respective subframe offsets of 4, 5, 6, and 7 ms.

[0161]

[0170] In some aspects, the RSSI measurement symbols may be consecutive for each TCI state in one periodicity. Example 605 illustrates consecutive RSSI measurement symbols. As shown, in a given measurement duration, RSSI measurements are performed for only one of beam 1, beam 3, beam 4, or beam 6. When RSSI measurements are performed consecutively, the RMTC may be configured differently for each TCI state, such as using different measurement durations (e.g., four subframes for beam 1 vs. three subframes for beam 4).

[0162]

[0171] As noted above, Figure 6 is provided as an example. Other examples may differ from those described with respect to Figure 6.
