[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 891,114, filed on August 23, 2019, entitled “BEAM DETERMINATION PRIOR TO BEAM ACTIVATION INDICATION,” and U.S. Non-Provisional Patent Application No. 16 / 947,825, filed on August 19, 2020, entitled “BEAM DETERMINATION PRIOR TO BEAM ACTIVATION INDICATION,” which are expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for beam determination prior to indication of activated beams. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include several base stations (BS) that may support communications for several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to a communication link from a BS to a UE, while an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, and even global level. New Radio NR (also known as 5G) is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards, as well as support beamforming, multiple input multiple output (MIMO) antenna technology, and carrier aggregation. However, as the demand for mobile broadband access continues to increase, further improvements need to be made in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0040] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms, and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0041] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0042] Figure 11 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0043] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access to UEs associated 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. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (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.

[0044] In some aspects, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on 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 the wireless network 100 through various types of backhaul interfaces (e.g., direct physical connections), virtual networks, etc. using any suitable transport network.

[0045] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or UE) and send transmissions of data to a downstream station (e.g., a UE or BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0046] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0047] A network controller 130 may be coupled to a set of BSs and may 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, directly or indirectly, for example, via a wireless or wired backhaul.

[0048] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), 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 computer, 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-mounted component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0049] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may, for example, provide connectivity to a network (e.g., a wide area network, such as the Internet or a cellular network) or to a 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 user premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, etc.

[0050] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can 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 can be deployed.

[0051] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0052] As mentioned above, Figure 1 This is provided as an example only. Other examples may differ from the combination of Figure 1 The content described.

[0053] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, where the UE may be Figure 1 Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general, T≥1 and R≥1.

[0054] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the (multiple) MCS selected for the 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, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0055] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 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, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where 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 information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0056] 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, CQI, etc.). 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 through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. 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 transmitted by the UE 120. The receive processor 238 may provide the decoded data to the 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 with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0057] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120 and / or Figure 2Any other components of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with beam determination before indicating an activated beam, as described in more detail elsewhere herein. Figure 2 Any other component of may perform or direct e.g. Figure 4 The process of 400 Figure 5 10 and / or other processes described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 4 The process of 400 Figure 5 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0058] In some aspects, the UE 120 may include components for receiving (e.g., using the antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, receive module 604, etc.) configuration for one or more TCI states, components for receiving (e.g., using the antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, receive module 604, etc.) downlink control information for scheduling downlink transmissions after a time offset, components for determining (e.g., using the receive processor 258, transmit processor 264, controller / processor 280, memory 282, determination module 606, etc.) a beam for receiving a downlink transmission prior to receiving an indication of an activated TCI state for one or more TCI states, components for receiving (e.g., using the antenna 252, DEMOD, MIMO detector 256, receive processor 258, controller / processor 280, receive module 604, etc.) a downlink transmission using a beam, and the like. In some aspects, the UE 120 may include means for determining (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, the determining component 1208, etc.) corresponding signal-to-interference-plus-noise ratio (SINR) measurements for a set of beams, means for sending (e.g., using the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, the transmitting component 1204, etc.) a measurement report for the set of beams identifying the corresponding SINR measurements, wherein the measurement report identifies the corresponding SINR measurements, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0059] In some aspects, the base station 110 may include means for sending (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, the transmit module 804, etc.) configuration for one or more TCI states, means for sending (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, the transmit module 804, etc.) downlink control information for scheduling downlink transmissions after a time offset, means for determining (e.g., using the transmit processor 220, the receive processor 238, the controller / processor 240, the memory 242, the determination module 806, etc.) a beam for sending a downlink transmission before sending an indication of an activated TCI state for the one or more TCI states, and means for sending (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, the transmit module 804, etc.) using a beam. 232, antenna 234, transmission module 804, etc.) downlink transmission components, etc. In some aspects, such components may include a combination of Figure 2 One or more components of the base station 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0060] As mentioned above, Figure 2 This is provided as an example only. Other examples may differ from the combination of Figure 2 The content described.

[0061] In 5G and other types of radio access technologies (RATs), beamforming can be used for communication between a UE and a base station, such as for millimeter wave communications, etc. In this case, the base station can provide the UE with a configuration of a TCI state, which respectively indicates the beams that the UE can use, such as for receiving a physical downlink shared channel (PDSCH). The base station can indicate the activated TCI state to the UE (e.g., via a medium access control-control element (MAC-CE)), and the UE can use the TCI state to select a beam for receiving the PDSCH. However, in some cases, downlink control information (DCI) may schedule the PDSCH before activating the TCI state of the PDSCH.

[0062] Some devices and techniques described herein facilitate selecting a beam for receiving a PDSCH before activating a TCI state for the PDSCH. For example, the UE may determine the beam to be used for receiving the PDSCH based on a selected beam for a synchronization signal block (SSB) received during an initial access process, or based on a selected beam for monitoring a control resource set (CORESET), before activating the TCI state for the PDSCH. In some aspects, the UE may determine the beam based on a time offset between receiving a DCI scheduling the PDSCH and receiving the PDSCH and / or based on whether the control information is configured to identify the TCI state.

[0063] Figure 3 is a diagram illustrating an example 300 of determining a beam prior to an indication of an activated beam according to aspects of the present disclosure. Figure 3 As shown, BS 110 and UE 120 may communicate using a beam determined prior to activating the TCI state. In some aspects, communication between BS 110 and UE 120 may occur after an initial access procedure performed by BS 110 and UE 120. For example, BS 110 may transmit one or more SSBs, and UE 120 may receive one or more SSBs, as part of the initial access procedure. In some aspects, BS 110 may transmit SSBs using a beam previously selected by BS 110, and UE 120 may receive SSBs using a beam previously selected by UE 120.

[0064] like Figure 3 As shown in , and by reference numeral 310, BS 110 may send and UE 120 may receive a configuration (e.g., a high-layer configuration) identifying one or more TCI states. For example, BS 110 may send the configuration via radio resource control (RRC) signaling or MAC-CE.

[0065] As shown by reference numeral 320, BS 110 may send and UE 120 may receive control information (e.g., DCI) that schedules downlink transmissions carried in PDSCH. In some aspects, the control information may schedule downlink transmissions after a time offset. The time offset may be an interval between a first time when the control information is received by UE 120 and a second time when the PDSCH is scheduled.

[0066] UE 120 may receive control information in a CORESET monitored by UE 120. For example, UE 120 may monitor the CORESET using a beam previously selected by UE 120. Similarly, BS 110 may have sent control information in a CORESET using a beam previously selected by BS 110. In some aspects, the CORESET may be included in a plurality of CORESETs of a search space monitored by UE 120 (e.g., using a corresponding beam).

[0067] In some aspects, the tci-PresentInDCI field may not be configured for the CORESET (e.g., the tci-PresentInDCI field may be disabled). That is, the TCI indication in the control information may not be configured for the CORESET. In this case, the control information may not identify a TCI state in one or more TCI states configured for the UE 120. In some aspects, the tci-PresentInDCI field may be enabled for the CORESET. That is, the TCI indication in the control information may be enabled for the CORESET. In this case, the control information may identify a TCI state in one or more TCI states configured for the UE 120.

[0068] As indicated by reference numeral 330, UE 120 may determine a beam to be used for receiving a downlink transmission carried in a PDSCH. UE 120 may determine the beam before receiving an indication (e.g., an activation command) of an activated TCI state among one or more TCI states configured for UE 120 from BS 110 (e.g., before receiving an indication of a beam to be used for receiving a PDSCH). UE 120 may determine the beam based at least in part on a time offset associated with the control information and / or a tci-PresentInDCI configuration (e.g., enabled or not enabled) of a CORESET.

[0069] In some aspects, the time offset satisfies a threshold (e.g., the time offset is greater than or equal to the threshold) and the tci-PresentInDCI field is not configured for the CORESET (e.g., the control information may not identify a TCI state). In this case, the UE 120 may determine a beam for the PDSCH that corresponds to a beam selected by the UE 120 for receiving an SSB as part of an initial access procedure from the BS 110. For example, the determined beam may be quasi-colocated with a beam for an SSB received during the initial access procedure. That is, the beam may be determined based at least in part on a quasi-colocation (QCL) assumption after an SSB in the initial access procedure (e.g., a demodulation reference signal port for the PDSCH is quasi-colocated with the SSB). In addition, in aspects where the time offset satisfies a threshold and the tci-PresentInDCI field is not configured for the CORESET, the UE 120 may determine a beam for the PDSCH that corresponds to a beam selected by the UE 120 for monitoring the CORESET (i.e., the CORESET carrying the control information). For example, the determined beam may be quasi-co-located with a beam used to monitor the CORESET. That is, the beam may be determined based at least in part on a QCL assumption following the CORESET. In some aspects, the threshold may be associated with a beam switching delay of the UE 120 (e.g., the threshold may be a duration of the QCL (timeDurationForQCL)).

[0070] In some aspects, the UE 120 may have a configuration that identifies whether the UE 120 determines the beam according to the initial access procedure or according to the CORESET when the time offset meets the threshold and the tci-PresentInDCI field is not configured for the CORESET. In this way, when the time offset meets the threshold and the tci-PresentInDCI field is not configured for the CORESET, the UE 120 may determine the beam in a consistent manner that enables the BS 110 to infer the beam determined by the UE 120.

[0071] In some aspects, the time offset may satisfy a threshold and may enable the tci-PresentInDCI field for the CORESET (e.g., the control information may identify the TCI state). In this case, the UE 120 may determine a beam for the PDSCH that corresponds to a beam selected by the UE 120 for the SSB received from the BS 110 as part of the initial access procedure, or to a beam selected by the UE 120 for monitoring the CORESET, as described above.

[0072] In some aspects, the UE 120 may have a configuration for identifying whether the UE 120 is to determine the beam according to the initial access procedure or according to the CORESET when the time offset meets the threshold and the tci-PresentInDCI field is enabled for the CORESET. In this way, when the time offset meets the threshold and the tci-PresentInDCI field is enabled, the UE 120 can determine the beam in a consistent manner, which enables the BS 110 to infer the beam determined by the UE 120.

[0073] In some aspects, the time offset does not satisfy the threshold (e.g., the time offset is less than the threshold). In this case, the UE 120 may determine a beam for the PDSCH that corresponds to a beam selected by the UE 120 to receive the SSB from the BS 110 as part of the initial access process, as described above. In addition, in aspects where the time offset does not satisfy the threshold, the UE 120 may determine a beam for the PDSCH that corresponds to a beam selected by the UE 120 to monitor a CORESET having a lowest identifier among identifiers of multiple CORESETs monitored by the UE 120 (e.g., a search space monitored by the UE 120). For example, the determined beam may be quasi-colocated with a beam used to monitor the CORESET having the lowest identifier. That is, the beam may be determined based at least in part on a QCL assumption that follows the CORESET having the lowest identifier. The multiple CORESETs may be associated with intervals (e.g., time slots) that were most recently monitored by the UE 120 (e.g., before the beams were determined).

[0074] In some aspects, UE 120 may have a configuration for identifying whether UE 120 is to determine the beam according to the initial access procedure or according to the CORESET with the lowest identifier when the time offset does not meet the threshold. In this way, when the time offset does not meet the threshold, UE 120 can determine the beam in a consistent manner, which enables BS 110 to infer the beam determined by UE 120.

[0075] As indicated by reference numeral 340, BS 110 may determine a beam to be used for transmitting a downlink transmission carried in the PDSCH. BS 110 may determine the beam before sending an indication of an activated TCI state of one or more TCI states configured for UE 120 to UE 120. As described above, BS 110 may determine the beam based at least in part on a time offset associated with the control information and / or a tci-PresentInDCI configuration of a CORESET.

[0076] For example, when the time offset satisfies the threshold and the tci-PresentInDCI field is not configured for the CORESET, the BS 110 may determine a beam corresponding to one of the beams selected by the BS 110 for transmitting the SSB in the initial access procedure or the beams selected by the BS 110 for transmitting the control information in the CORESET. As another example, when the time offset satisfies the threshold and the tci-PresentInDCI field is enabled for the CORESET, the BS 110 may determine a beam corresponding to one of the beams selected by the BS 110 for transmitting the SSB in the initial access procedure or the beams selected by the BS 110 for transmitting the control information in the CORESET. As another example, when the time offset does not satisfy the threshold, the BS 110 may determine a beam corresponding to the beam selected by the BS 110 for transmitting the SSB in the initial access procedure or one of the beams selected by the BS 110 and associated with the CORESET having the lowest identifier among the identifiers of the plurality of CORESETs monitored by the UE 120, as described above.

[0077] In each of the above examples, BS 110 may be configured to determine the beam in a manner corresponding to the manner configured as described above for UE 120. For example, when the time offset does not satisfy the threshold, if UE 120 is configured to determine a beam corresponding to a beam used for receiving SSBs during an initial access procedure, BS 110 may determine a beam corresponding to a beam used for transmitting SSBs during an initial access procedure.

[0078] As indicated by reference numeral 350, BS 110 may transmit a downlink transmission in the PDSCH, and UE 120 may receive the downlink transmission in the PDSCH. For example, BS 110 may transmit the downlink transmission using a beam determined by BS 110, and UE 120 may receive the downlink transmission using a beam determined by UE 120. In this manner, BS 110 may transmit the downlink transmission, and UE 120 may receive the downlink transmission, before activating the TCI state of the PDSCH.

[0079] As indicated by reference numeral 360, the BS 110 may send, and the UE 120 may receive, an indication (e.g., an activation command) of an activated TCI state of one or more TCI states configured for the UE 120. The BS 110 may send the indication via a MAC-CE. In some aspects, the BS 110 may send the indication of the activated TCI state regardless of whether the tci-PresentInDCI field is enabled for the CORESET. For example, the BS 110 may send the indication in a case where the tci-PresentInDCI field is not configured for the CORESET, and may send the indication in a case where the tci-PresentInDCI field is enabled for the CORESET.

[0080] In some aspects, BS 110 may send the indication along with (e.g., simultaneously or nearly simultaneously with) an indication of an activated TCI state (e.g., an activation command) of a physical downlink control channel (PDCCH) monitored by UE 120. The activated TCI state indicated for the PDSCH may correspond to (e.g., may be identical to) the activated TCI state indicated for the PDCCH.

[0081] In some aspects, when the TCI state of the PDSCH is activated, if the UE 120 determines a beam corresponding to the beam selected by the UE 120 for receiving the SSB in the initial access procedure before the TCI state is activated, the UE 120 may determine and use a beam corresponding to the beam selected by the UE 120 for monitoring the CORESET, as described above. For example, when the time offset meets the threshold and the tci-PresentInDCI field is not configured for the CORESET, the UE 120 may determine and use a beam corresponding to the beam selected by the UE 120 for monitoring the CORESET. In addition, when the TCI state of the PDSCH is activated, the BS 110 may similarly determine and use a beam corresponding to the beam selected by the BS 110 for transmitting control information in the CORESET.

[0082] In some aspects, upon activating the TCI state for the PDSCH, if, prior to activating the TCI state, the UE 120 determined a beam corresponding to a beam selected by the UE 120 for receiving an SSB in an initial access procedure, the UE 120 may determine and use a beam corresponding to a beam selected by the UE 120 for monitoring a CORESET with a lowest identifier, as described above. For example, when the time offset does not satisfy a threshold, the UE 120 may determine and use a beam corresponding to a beam selected by the UE 120 for monitoring a CORESET with a lowest identifier. Additionally, upon activating the TCI state for the PDSCH, the BS 110 may similarly determine and use a beam corresponding to a beam selected by the BS 110 and associated with a CORESET with a lowest identifier.

[0083] As mentioned above, Figure 3 This is provided as an example only. Other examples can be found in Figure 3 Different than described.

[0084] Figure 4 4 is a diagram illustrating an example process 400, performed, for example, by a UE, in accordance with aspects of the present disclosure. Example process 400 is an example of a UE (eg, UE 120, etc.) performing operations associated with beam determination prior to indication of an activated beam.

[0085] like Figure 4 As shown, in some aspects, process 400 may include receiving a configuration for one or more TCI states (block 410). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, receive module 604, etc.) may receive a configuration for one or more TCI states, as described above in conjunction with Figure 3 as described.

[0086] like Figure 4 As further shown in FIG. 4 , in some aspects, process 400 may include receiving downlink control information that schedules downlink transmissions after the time offset (block 420). For example, the UE (e.g., using components such as antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, receive module 604, etc.) may receive downlink control information that schedules downlink transmissions after the time offset, as described above in conjunction with Figure 3In a first aspect, a downlink transmission is carried in a physical downlink shared channel for data. In a second aspect, alone or in combination with the first aspect, the time offset is an interval between a first time when downlink control information scheduling the downlink transmission is received and a second time when the downlink transmission is scheduled.

[0087] like Figure 4 As further shown in FIG. 4 , in some aspects, process 400 may include determining a beam for receiving a downlink transmission prior to receiving an indication of an activated TCI state in one or more TCI states (block 430). For example, the UE (e.g., using controller / processor 280, etc.) may determine a beam for receiving a downlink transmission prior to receiving an indication of an activated TCI state in one or more TCI states, as described above in conjunction with Figure 3 as described.

[0088] In a third aspect, either alone or in combination with one or more of the first and second aspects, the time offset is greater than a threshold, and the TCI indication in the downlink control information is not enabled in the control resource set carrying the downlink control information that schedules the downlink transmission, and the determined beam corresponds to the beam used to receive the synchronization signal block in the initial access process. In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the process 400 also includes receiving (e.g., using the antenna 252, the DEMOD 254, the MIMO detector 256, the receive processor 258, the controller / processor 280, the receive module 604, etc.) an indication of an activated TCI state, and determining (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, the determination module 606, etc.) another beam corresponding to the beam used to monitor the control resource set. In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the time offset is greater than a threshold, and the TCI in the downlink control information indicates that the downlink control information scheduling the downlink transmission is carried in a control resource set that is not enabled, and the determined beam corresponds to a beam used to monitor the control resource set.

[0089] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the time offset is greater than a threshold and the TCI indication in the downlink control information is enabled in the control resource set that carries the downlink control information for scheduling the downlink transmission, and the determined beam corresponds to the beam used to receive the synchronization signal block in the initial access process. In a seventh aspect, either alone or in combination with one or more of the first to sixth aspects, the time offset is greater than a threshold and the TCI indication in the downlink control information is enabled in the control resource set that carries the downlink control information for scheduling the downlink transmission, and the determined beam corresponds to the beam used to monitor the control resource set.

[0090] In an eighth aspect, either alone or in combination with one or more of the first to seventh aspects, the time offset is less than a threshold, and the determined beam corresponds to a beam used to receive a synchronization signal block during an initial access process. In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, the process 400 further includes receiving (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receiving processor 258, controller / processor 280, receiving module 604, etc.) an indication of an activated TCI state, and determining (e.g., using receiving processor 258, transmitting processor 264, controller / processor 280, memory 282, determining module 606, etc.) another beam corresponding to the beam used to monitor the control resource set. In a tenth aspect, either alone or in combination with one or more of the first to ninth aspects, the control resource set has the lowest identifier among identifiers of multiple control resource sets in the most recent time slot being monitored. In the eleventh aspect, either alone or in combination with one or more of the first to tenth aspects, the time offset is less than a threshold and the determined beam corresponds to a beam for monitoring a control resource set having a lowest identifier among identifiers of multiple control resource sets being monitored.

[0091] In the twelfth aspect, alone or in combination with one or more of the first to eleventh aspects, the process 400 also includes: in a case where the TCI indication in the downlink control information is not enabled and the control resource set carries the downlink control information that schedules the downlink transmission, receiving (for example, using the antenna 252, DEMOD 254, MIMO detector 256, controller / processor 280, receiving module 604, etc.) an indication of an activated TCI state, and in a case where the TCI indication in the downlink control information is enabled and the control resource set carries the downlink control information that schedules the downlink transmission, receiving (for example, using the antenna 252, DEMOD 254, MIMO detector 256, receiving processor 258, controller / processor 280, receiving module 604, etc.) an indication of an activated TCI state. In the thirteenth aspect, either alone or in combination with one or more of the first to twelfth aspects, an indication of the activated TCI state is received together with another indication of another activated TCI state for receiving a control transmission, and the activated TCI state corresponds to another activated TCI state.

[0092] like Figure 4 As further shown in FIG. 4 , in some aspects, process 400 may include receiving a downlink transmission using a beam (block 440). For example, a UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, receive module 604, etc.) may receive a downlink transmission using a beam, as described above in conjunction with Figure 3 as described.

[0093] although Figure 4 Example blocks of process 400 are shown, but in some aspects, process 400 may include Figure 4 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in. Additionally or alternatively, two or more blocks of process 400 may be executed in parallel.

[0094] Figure 5 is a diagram illustrating an example process 500 performed, for example, by a BS, in accordance with aspects of the present disclosure. Example process 500 is an example of a BS (eg, BS 110, etc.) performing operations associated with beam determination prior to indicating an activated beam.

[0095] like Figure 5As shown, in some aspects, process 500 may include sending a configuration for one or more TCI states (block 510). For example, the BS (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, transmit module 804, etc.) may send a configuration for one or more TCI states, as described above in conjunction with Figure 3 as described.

[0096] like Figure 5 As further shown in FIG. 5 , in some aspects, process 500 may include sending downlink control information that schedules downlink transmissions after the time offset (block 520). For example, the BS (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, transmit module 804, etc.) may send downlink control information that schedules downlink transmissions after the time offset, as described above in conjunction with Figure 3 In a first aspect, a downlink transmission is carried in a physical downlink shared channel for data. In a second aspect, alone or in combination with the first aspect, the time offset is an interval between a first time when downlink control information scheduling the downlink transmission is received by the UE and a second time when the downlink transmission is scheduled.

[0097] like Figure 5 As further shown in FIG. 5 , in some aspects, process 500 may include determining a beam for transmitting a downlink transmission prior to transmitting an indication of an activated TCI state in one or more TCI states (block 530). For example, the BS (e.g., using controller / processor 240, determination module 806, etc.) may determine a beam for transmitting a downlink transmission prior to transmitting an indication of an activated TCI state in one or more TCI states, as described above in connection with Figure 3 as described.

[0098] In a third aspect, either alone or in combination with one or more of the first and second aspects, the time offset is greater than a threshold, and the TCI indication in the downlink control information is not enabled in the control resource set carrying the downlink control information that schedules the downlink transmission, and the determined beam corresponds to the beam used to send the synchronization signal block in the initial access process. In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the process 500 also includes sending (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the MOD 232, the antenna 234, the transmit module 804, etc.) an indication of the activated TCI state, and determining (e.g., using the transmit processor 220, the receive processor 238, the controller / processor 240, the memory 242, the determination module 806, etc.) another beam corresponding to the beam used to send the downlink control information. In the fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the time offset is greater than a threshold, and the TCI in the downlink control information indicates that the downlink control information scheduling the downlink transmission is carried in a control resource set that is not enabled, and the determined beam corresponds to the beam used to send the downlink control information.

[0099] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the time offset is greater than a threshold, and the TCI in the downlink control information indicates that the enabled control resource set carries the downlink control information for scheduling the downlink transmission, and the determined beam corresponds to the beam used to send the synchronization signal block in the initial access process. In a seventh aspect, either alone or in combination with one or more of the first to sixth aspects, the time offset is greater than a threshold, and the TCI in the downlink control information indicates that the enabled control resource set carries the downlink control information for scheduling the downlink transmission, and the determined beam corresponds to the beam used to send the downlink control information.

[0100] In an eighth aspect, either alone or in combination with one or more of the first to seventh aspects, the time offset is less than a threshold, and the determined beam corresponds to a beam used to transmit a synchronization signal block during an initial access process. In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, process 500 also includes sending (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD232, antenna 234, transmit module 804, etc.) an indication of an activated TCI state, and determining another beam based at least in part on a control resource set. In a tenth aspect, either alone or in combination with one or more of the first to ninth aspects, the control resource set has the lowest identifier among identifiers of multiple control resource sets in a most recent timeslot monitored by the UE. In an eleventh aspect, either alone or in combination with one or more of aspects one to ten, the time offset is less than a threshold and the beam is determined at least in part based on a control resource set having a lowest identifier among identifiers of multiple control resource sets monitored by the UE.

[0129] Fig. 9 Provided as an example. Other examples can be combined with Fig. 9 Different than described.

[0130] Fig.10 1 is a diagram illustrating an example 1000 of a beam group measurement report according to aspects of the present disclosure. Fig.10 As shown, example 1000 may include a BS 110 and a UE 120 in communication with each other.

[0131] As shown in reference numeral 1005, BS 110 may send a reporting configuration (e.g., CSI-ReportConfig), and UE 120 may receive the reporting configuration, which indicates that UE 120 will report signal-to-interference-plus-noise ratio (SINR) measurements. For example, the reporting configuration may include a reporting metric parameter (e.g., a higher-layer parameter reportQuantity) that identifies SINR as a reporting metric for the reporting configuration (e.g., the reportQuantity parameter is set to cri-SINR or ssb-Index-SINR). In some aspects, the reporting configuration or another configuration sent by BS 110 may indicate that measurement reporting for a group of beams is enabled for UE 120 (e.g., a higher-layer parameter groupBasedBeamReporting may be enabled).

[0132] As shown in reference numeral 1010, UE 120 may determine (e.g., obtain) corresponding SINR measurements for a set of beams. For example, UE 120 may determine corresponding layer 1 (L1) SINR (L1-SINR) measurements for the set of beams. A set of beams may include two or more beams on which UE 120 may perform simultaneous (e.g., parallel) transmission or reception. For example, a set of beams may include two or more beams on which UE 120 may simultaneously receive channel state information reference signal (CSI-RS) resources, SSB resources, etc.

[0133] As indicated by reference numeral 1015, UE 120 may send and BS 110 may receive a report (e.g., a measurement report) identifying a set of beams of corresponding SINR measurements. In some aspects, the report may identify a value for each of the corresponding SINR measurements. In some aspects, the values ​​may represent actual SINR measurements for the set of beams. In some aspects, the values ​​indicated in the report may be quantized values ​​(e.g., according to a mapping of quantized values ​​to SINR measurements).

[0134] In some aspects, the report may identify the value of the maximum (or minimum) SINR measurement result of the corresponding SINR measurement result. In this case, the maximum SINR measurement result may represent the actual SINR measurement result of the beam of a set of beams, and the value may be a quantized value, as described above. In addition, the report may identify the corresponding differential value of the remainder of the corresponding SINR measurement result (e.g., the corresponding SINR measurement result other than the maximum SINR measurement result) relative to the value of the maximum SINR measurement result. The differential value of a specific SINR measurement result may represent the difference between the maximum SINR measurement result and the specific SINR measurement result. In some aspects, the differential value may be a quantized value (e.g., according to a mapping of the quantized value to the differential value), as described above.

[0138] like Fig.11 As further shown, in some aspects, process 1100 may include sending a measurement report for the set of beams identifying the corresponding SINR measurements (block 1120). For example, the UE (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, transmit component 1204, etc.) may send a measurement report for the set of beams, the measurement report identifying the corresponding SINR measurements.

[0139] In a first aspect, the measurement report identifies a value of a maximum SINR measurement result among the respective SINR measurements and respective differential values ​​relative to the value of the maximum SINR measurement result for the remainder of the respective SINR measurements.

[0154] Fig.13 Provided as an example. Other examples can be combined with Fig.13 Different than described.

[0155] Fig.14 is a diagram illustrating an example process 1400 performed, for example, by a UE, in accordance with aspects of the present disclosure. Example process 1400 is an example of operations in which a UE (eg, UE 120, etc.) performs operations associated with receiving CSI in a resource set.

[0156] like Fig.14 As shown, in some aspects, process 1400 may include receiving a configuration for a first non-zero power (NZP) channel state information (CSI) resource set to be used for channel measurement, a second NZP CSI resource set to be used for interference measurement, and a zero power (ZP) CSI resource set to be used for interference measurement (block 1410). For example, a UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive a configuration for a first non-zero power (NZP) channel state information (CSI) resource set to be used for channel measurement, a second NZP CSI resource set to be used for interference measurement, and a zero power (ZP) CSI resource set to be used for interference measurement.

[0157] In a first aspect, the first NZP CSI resource set, the second NZP CSI resource set, and the ZP CSI resource set have the same number of resource sets.

[0158] In a second aspect, alone or in combination with the first aspect, the resource set of the first NZP CSI resource set comprises a different amount of resources than the resource set of the second NZP CSI resource set or the resource set of the ZP CSI resource set.

[0159] like Fig.14 As further shown, in some aspects, process 1400 may include receiving, using a beam, first NZP CSI in a resource set at a particular index position of a first NZP CSI resource set (block 1420). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may receive, using a beam selected based on a quasi-co-location assumption associated with the particular index position, first NZP CSI in a resource set at a particular index position of a first NZP CSI resource set.

[0160] like Fig.14 As further shown, in some aspects, process 1400 may include receiving, using a beam, second NZP CSI in a resource set at a specific index position of a second NZP CSI resource set (block 1430). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may receive, using a beam, second NZP CSI in a resource set at a specific index position of a second NZP CSI resource set.

[0161] like Fig.14 As further shown in FIG. 14 , in some aspects, process 1400 may include receiving ZP CSI in a resource set at a specific index position of a ZP CSI resource set using a beam (block 1440). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may receive ZP CSI in a resource set at a specific index position of a ZP CSI resource set using a beam.

[0162] although Fig.14 Example blocks of process 1400 are shown, but in some aspects, process 1400 may include Fig.14 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in. Additionally or alternatively, two or more blocks of process 1400 may be executed in parallel.
