Techniques for configuring multi-SCS and multi-beam directional communications

Abstract

Methods, systems, and apparatus for wireless communications in an unlicensed spectrum are described. In some wireless communication systems, a user equipment may identify service parameters configured for the user equipment for a shared radio frequency channel, such as a subcarrier spacing or a beam direction of a directional beam for communicating with a base station. The base station may obtain a channel occupancy time of the shared radio frequency channel. The user equipment may monitor and receive control messages for the channel occupancy time from the base station. The control message may include an indication of a service associated with the service parameter and an indication of a remaining duration of the channel occupancy time. Based on these indications, the user equipment may adapt one or more reception parameters (e.g., monitoring periodicity, monitoring timing, and whether to skip monitoring) for communicating with the base station during the channel occupancy time.

Background Art

[0003] The following relates generally to wireless communications in unlicensed spectrum, and more particularly to techniques for configuring multiple subcarrier spacing (SCS) and multiple beam direction communications.

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems that may be referred to as new radio (NR) systems. These systems may use various technologies, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform extended orthogonal frequency division multiplexing (DFT-s-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each of which simultaneously supports the communication of multiple communication devices, which may be referred to as user equipment (UE).

[0005] In some cases, a base station may serve several UEs within a serving cell. The UE may monitor downlink control communications from the base station (such as at a slot level or at a mini-slot level). In some cases, the UE may switch from using slot-level monitoring to mini-slot-level monitoring, or the UE may switch from using mini-slot-level monitoring to slot-level monitoring. In addition, in some cases, different UEs may communicate with the base station using different SCSs from each other. In some cases, the base station may communicate with different UEs located at different physical locations using different directional beams. Therefore, different SCSs and directional beams used for communication between the UE and the base station may complicate the UE's monitoring of downlink control information.

In general, the described techniques provide for a user equipment (UE) to identify service parameters configured for the UE for a carrier associated with a shared radio frequency channel. The service parameters may include an SCS that the UE may use to communicate with a base station or a beam direction of a directional beam that the UE may use to communicate with a base station. The base station may also determine the service parameters for the UE.

[0008] The base station may perform a channel access procedure to acquire a channel occupancy time (COT) of a shared radio frequency channel. The UE may monitor a control message from the base station, such as a physical downlink control channel (PDCCH), and the UE may receive a control message for the COT acquired by the base station for the shared radio frequency channel. The control message may include an indication of a service associated with a service parameter via a carrier. Based on the indication of the service, the UE may determine a communication parameter (such as a monitoring level) for communicating with the base station during the COT to, for example, receive downlink communications.

The method may include identifying a service parameter configured for the UE for a carrier associated with a shared radio frequency channel; receiving from a base station a control message associated with a COT acquired by the base station for the shared radio frequency channel, wherein the control message includes an indication of a service associated with the service parameter via the carrier within the COT; and determining one or more communication parameters for communicating with the base station during the COT based on the indication.

[0042] Detailed Description

[0043] Various aspects of the present disclosure relate to methods, systems, devices, and apparatuses that support multi-subcarrier spacing (SCS) and multi-beam direction communications. In some aspects, a serving cell may include a base station that serves several UEs. The UE may monitor downlink control communications from the base station, such as a physical downlink control channel (PDCCH). In different implementations, the UE may monitor the PDCCH at a slot level or at a mini-slot level, where the slot may include multiple mini-slots and each mini-slot may include one or more symbols. In some cases, a base station may acquire a channel (e.g., a channel in a shared or unlicensed radio frequency spectrum band) and may transmit and / or receive within a channel occupancy time (COT). In some cases, the COT may be limited in duration by constraints on the device using the spectrum band. In some cases, the UE may switch from using mini-slot level monitoring to slot level monitoring during the COT after determining the start time of the COT. By switching from mini-slot level monitoring to slot level monitoring, the UE may monitor the PDCCH less frequently and therefore consume less power.

[0044] In some cases, one or more UEs in a serving cell may operate according to SCSs that are distant from each other. Thus, for a particular transmission opportunity, a base station may transmit a control message (e.g., a COT system information (COT-SI) message) to one or more UEs in a serving cell according to a first SCS, and if the COT SI transmission is configured for the first SCS, a UE operating according to a different SCS may not recognize the COT SI transmission. Additionally or alternatively, a base station may communicate with a UE using a directional beam, and for a particular transmission opportunity, the base station may transmit a COT-SI message to one or more UEs in a serving cell according to a first beam direction, and thus a UE in a different direction may not receive the COT SI transmission.

[0045] Described herein are techniques by which a base station may transmit control information to a UE in a serving cell, wherein the control information is configured for each SCS in an SCS that may be used by the UE in the serving cell of the base station. Similarly, described herein are techniques by which a base station may transmit control information to a UE in a serving cell using a directional beam in the direction of each UE in the serving cell of the base station. Additionally or alternatively, a base station may transmit an idle COT-SI message to one or more UEs in the serving cell of the base station, wherein the idle COT-SI message may indicate to the one or more UEs that the SCS and / or beam index of the UE may not be served during a corresponding transmission opportunity. In this way, the base station may allow the UE to enter a lower power mode (e.g., not monitor control messages) during a transmission opportunity.

[0046] According to the techniques described herein, in some cases, an anchor carrier may be used to provide information to one or more UEs, the information indicating an SCS and / or beam index and an associated time duration (e.g., a transmission opportunity and / or an additional amount of time), wherein the information indicates an SCS and / or beam index that may be used or not used during the time duration. This document further describes techniques by which a base station may transmit a signal (e.g., a reference signal or a wake-up signal) to one or more UEs, the signal identifying an upcoming downlink transmission burst in a corresponding transmission opportunity. Additionally or alternatively, the base station may transmit a common preamble for all SCSs to the UE, wherein the common preamble may include, in some cases, a bitmap of served and / or unserved SCSs and an indication of the duration of the associated transmission opportunity. Thus, a UE that is not served may not monitor communications during a transmission opportunity, thereby saving power at the UE.

[0047] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of transmission timelines and process flows are subsequently provided according to some aspects of the present disclosure. Various aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow charts related to techniques for configuring multiple SCSs and multiple beam direction communications.

[0048] Figure 1 Various aspects of a wireless communication system 100 that supports techniques for configuring multi-SCS and multi-beam direction communications according to various aspects of the present disclosure are illustrated. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some aspects, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, or communications with low-cost and low-complexity devices.

[0049] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home Evolved Node B, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be able to communicate with various types of base stations 105 and network equipment (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0050] Each base station 105 may be associated with a particular geographic coverage area 110 in which it supports communications with various UEs 115. Each base station 105 may provide communications coverage for a respective geographic coverage area 110 via a communications link 125, and the communications link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communications link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

[0051] The geographic coverage area 110 of the base station 105 may be divided into sectors that constitute a portion of the geographic coverage area 110, and each sector may be associated with a cellular cell. According to some aspects, each base station 105 may provide communication coverage for a macrocellular cell, a small cellular cell, a hotspot, or other types of cellular cells, or various combinations thereof. In some aspects, the base station 105 may be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some aspects, different geographic coverage areas 110 associated with different technologies may overlap, and overlapping geographic coverage areas 110 associated with different technologies may be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may include systems such as heterogeneous LTE / LTE-A / LTE-A Pro or NR networks, in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0052] The term "cell" refers to a logical communication entity used to communicate with base station 105 (e.g., on a carrier), and may be associated with an identifier to distinguish adjacent cells operating via the same or different carriers (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)). In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or others). In some cases, the term "cell" may refer to a portion (e.g., a sector) of a geographic coverage area 110 on which the logical entity operates.

[0053] Each UE 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. UE 115 can also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device or some other suitable term, wherein "device" can also be referred to as a unit, a station, a terminal or a client. UE 115 can also be a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer or a personal computer. In some aspects, UE 115 can also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which can be implemented in various items such as electrical appliances, vehicles, meters, etc.

[0054] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some aspects, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay the information to a central server or application, which may utilize the information or present the information to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0055] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some aspects, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving "deep sleep" mode when not engaged in active communications, or operating over a limited bandwidth (e.g., in accordance with narrowband communications). In some cases, UE 115 may be designed to support critical functions (e.g., mission critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communications for these functions.

[0056] In some cases, UE 115 may also be able to communicate directly with other UE 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more UEs in a group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in this group may be outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some cases, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between each UE 115 without involving the base station 105.

[0057] The base stations 105 may communicate with the core network 130 and with each other. According to some aspects, the base stations 105 may interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 may communicate with each other over a backhaul link 134 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130).

[0058] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access layer (e.g., control plane) functions such as mobility, authentication, and bearer management of UEs 115 served by base stations 105 associated with the EPC. User IP packets may be delivered through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet switched (PS) streaming services.

[0059] At least some network devices (such as base stations 105) may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with each UE 115 through a number of other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers) or merged into a single network device (e.g., base station 105).

[0060] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths are in the range of from about 1 decimeter to 1 meter long. UHF waves can be blocked or redirected by buildings and environmental features. However, these waves can penetrate various structures sufficiently for macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to transmission using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0061] The wireless communication system 100 may also operate in the Super High Frequency (SHF) region using frequency bands from 3 GHz to 30 GHz, also known as centimeter bands. The SHF region includes frequency bands that may be opportunistically used by devices that may be able to tolerate interference from other users, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band.

[0062] The wireless communication system 100 may also operate in the extremely high frequency (EHF) division of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as the millimeter band. In some aspects, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antenna of the corresponding device may be even smaller and more closely spaced than the UHF antenna. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency divisions, and the use of frequency bands specified across these frequency divisions may differ by country or regulatory agency.

[0063] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. According to some aspects, the wireless communication system 100 may adopt license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as a 5GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (such as base stations 105 and UE 115) may adopt a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operations in unlicensed bands can be based on carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in licensed bands. Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum may be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of the two.

[0064] In some aspects, the base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. According to some aspects, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., base station 105) and a receiving device (e.g., UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication may employ multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. In some cases, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of these multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0065] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or direct an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying a particular amplitude and phase shift to the signal carried via each antenna element associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0066] In one aspect, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions, which may include a signal being transmitted according to different beamforming weight sets associated with different transmission directions. The transmissions in different beam directions may be used (e.g., by the base station 105 or a receiving device, such as the UE 115) to identify a beam direction for subsequent transmission and / or reception by the base station 105.

[0067] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some aspects, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in different beam directions. According to some aspects, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signals received by it with the highest signal quality or other acceptable signal quality. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a recipient device).

[0068] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may attempt multiple receive beams when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. According to some aspects, the receiving device may attempt multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some aspects, the receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). The single receive beam may be aligned on a beam direction determined based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or other acceptable signal quality based on listening according to multiple beam directions).

[0069] In some cases, the antennas of the base station 105 or UE 115 may be located within one or more antenna arrays that may support MIMO operations or transmit or receive beamforming. According to some aspects, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some cases, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0070] In some cases, the wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use a hybrid automatic repeat request (HARQ) to provide retransmission of the MAC layer, thereby improving link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration and maintenance of an RRC connection for a radio bearer that supports user plane data between UE115 and base station 105 or core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0071] In some cases, UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood of correctly receiving data on communication link 125. HARQ may include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput of the MAC layer in poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0072] The time interval in LTE or NR can be represented by a basic time unit (which may refer to a sampling period T, for example). s =1 / 30,720,000 seconds). The time intervals of the communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period may be expressed as T f =307,200T s . A radio frame may be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1 ms. A subframe may be further divided into 2 slots, each slot having a duration of 0.5 ms, and each slot may contain 6 or 7 modulation symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). Excluding the cyclic prefix, each symbol period may contain 2048 sampling periods. In some cases, a subframe may be the minimum scheduling unit of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0073] In some wireless communication systems, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. In some instances, a symbol of a mini-slot or a mini-slot may be a minimum scheduling unit. Each symbol may vary in duration depending on the SCS or operating band. Further, some wireless communication systems may implement time slot aggregation, wherein a plurality of time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0074] The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communications on the communication link 125. According to some aspects, the carrier of the communication link 125 may include a portion of a radio frequency spectrum band that operates according to a physical layer channel for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by a UE 115. A carrier may be a downlink or an uplink (e.g., in an FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in a TDD mode). In some aspects, a signal waveform transmitted on a carrier may include multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-s-OFDM)).

[0075] The organization structure of the carrier may be different for different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR). According to some aspects, communications on a carrier may be organized according to TTIs or time slots, each of which may include user data and control information or signaling to support decoding of the user data. A carrier may also include dedicated acquisition signaling (e.g., synchronization signals or system information (SI), etc.) and control signaling to coordinate carrier operations. In some aspects (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers.

[0076] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, such as using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some aspects, control information transmitted in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0077] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some aspects, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be a predetermined bandwidth (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz) among several predetermined bandwidths of a carrier of a particular radio access technology. In some aspects, each served UE 115 may be configured to operate on part or all of the carrier bandwidth. In other aspects, some UEs 115 may be configured to use operations of a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0078] In a system using MCM technology, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and SCS are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate of communication with UE 115.

[0079] A device (e.g., a base station 105 or a UE 115) of the wireless communication system 100 may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support communication on one of a set of carrier bandwidths. In some aspects, the wireless communication system 100 may include a base station 105 and / or a UE 115 that supports simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0080] The wireless communication system 100 may support communication with the UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both FDD and TDD component carriers.

[0081] In some cases, the wireless communication system 100 may utilize an enhanced component carrier (eCC). An eCC may be characterized by one or more features including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC may also be configured for use in an unlicensed spectrum or a shared spectrum (e.g., where more than one operator is allowed to use the spectrum). An eCC characterized by a wide carrier bandwidth may include one or more segments that may be utilized by a UE 115 that is not capable of monitoring the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., to save power).

[0082] In some cases, an eCC may utilize a different symbol duration than other component carriers, which may include using a reduced symbol duration compared to the symbol duration of other component carriers. A shorter symbol duration may be associated with an increased spacing between adjacent subcarriers. A device utilizing an eCC (such as a UE 115 or a base station 105) may transmit a wideband signal (e.g., according to a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may include one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0083] The wireless communication system 100 may be an NR system that may utilize any combination of licensed, shared, and unlicensed spectrum bands, etc. The flexibility of eCC symbol duration and SCS may allow the use of eCC across multiple spectrums. In some aspects, NR shared spectrum may improve spectrum utilization and spectrum efficiency, particularly through dynamic vertical (e.g., across frequency domain) and horizontal (e.g., across time domain) sharing of resources.

[0084] A serving cell may include a base station 105 that serves a number of UEs 115, such as a number of UEs within a geographic coverage area 110 associated with the corresponding base station 105. The UE 115 may monitor downlink control communications, such as the PDCCH, from the base station 105. In different implementations, the UE 115 may monitor the PDCCH at a slot level or at a mini-slot level, where a slot may include multiple mini-slots and each mini-slot may include one or more symbols. In some cases, the base station 105 and the UE 115 may be configured with a COT that defines the amount of time that the UE 115 will occupy the channel within a particular transmission opportunity.

[0085] In some cases, the UE 115 may switch from using slot-level monitoring to mini-slot-level monitoring, or the UE 115 may switch from using mini-slot-level monitoring to slot-level monitoring. According to some aspects, the UE 115 may switch from using mini-slot-level monitoring to slot-level monitoring after the transmission opportunity begins, and the UE 115 may continue to use slot-level monitoring until the transmission opportunity ends, at which time the UE 115 may switch back to mini-slot-level monitoring. By switching to slot-level monitoring, the UE 115 may monitor the PDCCH less frequently and may therefore consume less power. In some cases, the base station 105 may indicate the start of a transmission opportunity to the UE 115 in another (e.g., earlier) control message (such as an earlier PDCCH, a group-shared PDCCH, an SI message (e.g., a COT-SI message, i.e., an SI message associated with a specific COT) and / or a wake-up signal. Similarly, in some cases, base station 105 may indicate the end of a transmission opportunity to UE 115 in additional control messages, such as PDCCH, SI messages (eg, COT-SI messages), and / or wake-up signals.

[0086] In some cases, one or more UEs 115 in a serving cell may operate according to different SCSs that are distant from each other. Thus, for a particular transmission opportunity, a base station may transmit a COT-SI message to one or more UEs 115 in a serving cell according to a first SCS, and if the COT SI transmission is specifically configured for the first SCS, a UE 115 operating according to a different second SCS may not recognize the COT SI transmission. According to some aspects, if a transmission opportunity would be entirely a first SCS (e.g., 15 kilohertz (kHz)), a UE 115 operating according to a second SCS (e.g., 30 kHz) may not detect the COT SI transmission, and thus the UE 115 may not switch from mini-slot level monitoring to slot level monitoring for the corresponding transmission opportunity, and may not realize the power savings of the switch for the duration of the transmission opportunity.

[0087] In some cases, the base station 105 may communicate with the UE 115 using directional beams, wherein the base station 105 may communicate with the UE 115 in different physical locations using beams in different beam directions. Thus, for a particular transmission opportunity, in a similar manner as described for different SCSs, the base station 105 may transmit a COT-SI message to one or more UEs 115 in the serving cell according to a first beam direction, and thus a UE 115 configured to receive a different second beam direction may not receive the COT SI transmission. Thus, for the corresponding transmission opportunity, the UE 115 may not switch from mini-slot level monitoring to slot level monitoring, and similarly may not realize the power savings of the switch within the duration of the transmission opportunity.

[0088] Furthermore, in some cases, to save power outside of the COT, the base station may transmit a signal (such as a wake-up signal or a reference signal (e.g., a demodulation reference signal (DMRS) or a PDCCH or a preamble, etc.) to the UE 115, which may indicate to the UE 115 an upcoming COT for the transmission opportunity. Based on the signal, the UE 115 may switch from mini-slot level monitoring to slot level monitoring before the transmission opportunity, thereby achieving power savings within the duration. However, when different UEs 115 are configured with different SCSs, the UE 115 may not receive the signal correctly, and therefore may not achieve these power savings.

[0089] Thus, described herein are techniques by which a base station 105 may transmit control information to a UE 115 in a serving cell, wherein the control information is configured for each of the SCSs that may be used by the UE 115 in the serving cell of the base station 105. Similarly, described herein are techniques by which a base station 105 may transmit control information to a UE 115 in a serving cell using a directional beam in the direction of each UE 115 in the serving cell of the base station 105. Additionally or alternatively, the base station may transmit an idle COT-SI message to one or more UEs 115 in the serving cell of the base station 105, wherein the idle COT-SI message may indicate to the one or more UEs 115 that the SCS and / or beam index (e.g., corresponding to the indexed beam direction) of the UE 115 is not being served during the corresponding transmission opportunity. In this manner, the base station 105 may silence the UE 115, thereby providing power savings for the silenced UE 115 that will not be monitoring communications during the transmission opportunity.

[0090] According to the techniques described herein, in some cases, an anchor carrier may be used to provide information to one or more UEs 115 indicating an SCS and / or beam index and an associated time duration (e.g., a transmission opportunity and / or an additional amount of time), wherein the information indicates an SCS and / or beam index that may be used or not used during the time duration. Further described herein are techniques in which a base station 105 may transmit a signal (e.g., a reference signal or a wake-up signal) to one or more UEs 115 that identifies an upcoming downlink transmission burst in a corresponding transmission opportunity to the UE 115. According to some aspects, the base station 105 may transmit a wake-up signal indicating a served SCS and / or beam direction, and / or the wake-up signal may indicate an SCS and / or beam direction that may not be served during the transmission opportunity. Additionally or alternatively, the base station 105 may transmit a common preamble of all SCSs to the UE 115, wherein the common preamble may include, in some cases, a bitmap of served and / or unserved SCSs and an indication of the duration of the associated transmission opportunity. Thus, UEs 115 that are not being served may not monitor communications during a transmission opportunity, thereby saving power at the UE 115.

[0091] Figure 2 Illustrate aspects of a transmission timeline 200 that supports techniques for configuring multiple SCSs and multiple beam direction communications in accordance with aspects of the present disclosure. In some aspects, the transmission timeline 200 may be implemented as described with reference to Figure 1 Aspects of the wireless communication system 100 described herein. The transmission timeline 200 may include operations performed by the base station 105-a, the first UE 115-a, and the second UE 115-b. Each of the base station 105 and the UE 115 may be a reference Figure 1 Examples of corresponding devices described. The first UE 115 - a and the second UE 115 - b may be in a serving cell of the base station 105 .

[0092] Transmission timeline 200 illustrates a transmission opportunity 203 that includes a number of time slots 205 configured with a first duration for a first SCS (e.g., 15 kHz) and a number of time slots 210 configured with a second duration for a second SCS (e.g., 30 kHz). In some cases, for a particular transmission opportunity 203, base station 105-a may transmit a control message (such as a COT-SI) to one or more UEs 115 (including, for example, all UEs 115 of a serving cell of base station 105-a).

[0093] In some cases, the COT-SI message may include one or more fields for a start time (e.g., a starting point) for the COT, a total duration of the COT, a remaining duration of the COT, a slot format indication (e.g., indicating whether the corresponding symbol of the COT is configured for uplink communication or downlink communication). The control message may indicate to the UE 115 the monitoring periodicity, one or more monitoring time opportunities, and whether to skip monitoring within a time period (e.g., within the remaining duration of the COT). According to some aspects, the control message may indicate to the UE 115 to switch to slot-level monitoring (e.g., from mini-slot-level monitoring). For example, during the first slot 205 of the transmission opportunity 203, the base station 105-a may transmit a control message 215 (such as a COT-SI) for a UE 115 configured for 15kHz SCS communication. Similarly, during the next slot 210 of the transmission opportunity 203, the base station 105-a may transmit a control message 220 (such as a COT-SI) for a UE 115 configured for 30kHz SCS communication.

[0094] As shown in transmission timeline 200, UE 115 may monitor communications (e.g., PDCCH) from base station 105-a during number of monitoring periods 225. According to some aspects, a first UE 115-a (e.g., a first UE 115-a configured for communication using 15kHz SCS) may first monitor at the mini-slot level until monitoring period 230, during which UE 115-a may receive 15kHz SCS control message 215 from base station 105-a. Based on control message 215, UE 115-a may switch to slot-level monitoring. Although base station 105-a may also transmit control message 220 to UE 115-a, UE 115-a may not detect control message 220 because control message 220 may be configured for 30kHz SCS communication. After slot-level monitoring, UE 115-a may detect 15kHz SCS communications during slots configured for 15kHz SCS downlink burst transmissions (in some cases, during monitoring period 235 and monitoring period 240). After the duration of transmission opportunity 203, UE 115-a may then return to mini-slot-level monitoring.

[0095] Similarly, the second UE 115-b may also first monitor at the mini-slot level until the monitoring period 245. Although the base station 105-a may also transmit the control message 215, the UE 115-b may not detect the control message 215 because the control message 215 may be configured for 15kHz SCS communication. Therefore, the UE 115-b may not receive the signaling to switch the monitoring level. However, during the monitoring period 245, the UE 115-b may receive a 30kHz SCS control message 220 from the base station 105-a. Based on the control message 220, the UE 115-b may switch to slot-level monitoring (e.g., based on the duration of the 30kHz SCS slot 210). After the slot-level monitoring, the UE 115-b may detect 30kHz SCS downlink burst communications during the slots configured for 30kHz SCS transmissions (such as in the monitoring period 250). After the duration of the transmission opportunity 203, the UE 115-b may then return to mini-slot level monitoring.

[0096] Figure 3 Illustrate aspects of a transmission timeline 300 that supports techniques for configuring multiple SCSs and multiple beam direction communications in accordance with aspects of the present disclosure. In some aspects, the transmission timeline 300 may be implemented as described with reference to Figure 1 Aspects of the wireless communication system 100 described herein. The transmission timeline 300 may include operations performed by the base station 105-b, the first UE 115-c, and the second UE 115-d. Each of the base station 105 and the UE 115 may be a reference Figure 1 An example of a corresponding device is described. The first UE 115-c and the second UE 115-d may be in a serving cell of the base station 105. In the case of the transmission timeline 300, the base station 105-b may be specifically configured for downlink transmissions using a 15kHz SCS during the transmission opportunity 303.

[0097] That is, the transmission timeline 300 shows a transmission opportunity 303 that includes a number of time slots 305 of a first duration configured for a first SCS (e.g., 15 kHz). In some cases, for a particular transmission opportunity 303, the base station 105-b may transmit a control message (such as a COT-SI) to one or more UEs 115 (including, for example, all UEs 115 of a serving cell of the base station 105-b). As similarly described herein, the control message may indicate to the UE 115 to switch to time slot level monitoring (e.g., from mini-slot level monitoring). According to some aspects, during the first time slot 305 of the transmission opportunity 303, the base station 105-b may transmit a control message 315 (such as a COT-SI) for the UE 115 configured for 15 kHz SCS communication. Because the transmission opportunity 303 is not configured for 30 kHz SCS communication, the base station 105 - b may transmit a control message 320 , such as a COT-SI, for the UE 115 configured for 30 kHz SCS communication prior to the first time slot 305 .

[0098] As shown in the transmission timeline 300, the UE 115 may monitor communications (e.g., PDCCH) from the base station 105-b during a number of monitoring periods 325. According to some aspects, a first UE 115-c (e.g., a first UE 115-a configured to communicate using 15kHz SCS) may first monitor at the mini-slot level until a monitoring period 330, during which the UE 115-c may receive a 15kHz SCS control message 315 from the base station 105-b. Based on the control message 315, the UE 115-c may switch to slot-level monitoring. Although the base station 105-b may also transmit a control message 320 to the UE 115-c prior to the transmission opportunity 303, the UE 115-c may not detect the control message 320 because the control message 320 may be configured for 30kHz SCS communications, while the UE 115-c may be configured for 15kHz SCS communications. After slot-level monitoring, the UE 115-c may detect 15kHz SCS communications during slots configured for 15kHz SCS downlink burst transmissions, such as in monitoring period 335, monitoring period 340, monitoring period 345, and monitoring period 350. After the duration of transmission opportunity 303, the UE 115-c may then return to mini-slot-level monitoring.

[0099] The second UE 115-d may also initially monitor at the mini-slot level until the monitoring period. Prior to the transmission opportunity 303, and during the monitoring period 355, the UE 115-d may receive a 30kHz SCS control message 320 from the base station 105-b. Based on the control message 320, the UE 115-d may switch to slot-level monitoring in the next monitoring period 360 after the monitoring period 355 during which the UE 115-d received the control message 320. However, because the base station 105-b may be specifically configured for downlink transmissions using 15kHz SCS during the transmission opportunity 303, the UE 115-d may not identify or receive any further downlink communications during the transmission opportunity 303. After the duration of the transmission opportunity 303, the UE 115-d may then return to mini-slot-level monitoring.

[0100] Figure 4 400 that supports techniques for configuring multiple SCS and multiple beam direction communications in accordance with aspects of the present disclosure. In some aspects, the transmission timeline 400 may be implemented as described with reference to Figure 1 Aspects of the wireless communication system 100 described herein. The transmission timeline 400 may include operations performed by the base station 105-c, the first UE 115-e, and the second UE 115-f. Each of the base station 105 and the UE 115 may be a reference Figure 1 An example of a corresponding device is described. The first UE 115-e and the second UE 115-f may be in a serving cell of the base station 105. In the case of the transmission timeline 400, the base station 105-c may be specifically configured for downlink transmissions using a 15kHz SCS during the transmission opportunity 403.

[0101] In some cases, such as Figure 44, the base station 105-c may transmit an idle control message 420 (e.g., an idle COT-SI message) to one or more UEs 115 in a serving cell of the base station 105. The idle control message 420 may indicate to one or more UEs 115 (e.g., UE 115-f) that the SCS of the UE 115 (or, for example, a beam index corresponding to a beam direction of the UE 115-f, as further described herein) is not being served during the transmission opportunity 403. In some cases, the idle control message 420 may be a one-bit indication that is added to or included in the corresponding control message. In some cases, the idle control message 420 may further indicate an additional silence duration following the transmission opportunity 403 (or, alternatively, a total silence duration that replaces the duration of the transmission opportunity 403) during which the UE 115-f may remain in a low power state (e.g., in a scenario where the base station 105-c is aware that the base station 105-c will not transmit downlink communications using 30kHz SCS for an extended period of time).

[0102] In accordance with some aspects, the transmission timeline 400 shows a transmission opportunity 403 that includes a number of time slots 405 of a first duration configured for a first SCS (e.g., 15 kHz). The base station 105-c may transmit a control message (such as a COT-SI) to one or more UEs 115 (including, for example, all UEs 115 of a serving cell of the base station 105-c). As similarly described herein, the control message may indicate to the UE 115 to switch to time slot level monitoring (e.g., from a mini-slot level monitoring). In accordance with some aspects, during the first time slot 405 of the transmission opportunity 403, the base station 105-c may transmit a control message 415 (such as a COT-SI) for the UE 115 configured for 15 kHz SCS communication. Because the transmission opportunity 403 is not configured for 30 kHz SCS communication, the base station 105-c may transmit an idle control message 420 before the first time slot 405 for the UE 115 configured for 30 kHz SCS communication.

[0103] As shown in the transmission timeline 400, the UE 115 may monitor communications (e.g., PDCCH) from the base station 105-c during a number of monitoring periods 425. According to some aspects, a first UE 115-e (e.g., a first UE 115-e configured to communicate using 15kHz SCS) may first monitor at the mini-slot level until a monitoring period 430, during which the UE 115-a may receive a 15kHz SCS control message 415 from the base station 105-c. Based on the control message 415, the UE 115-e may switch to slot-level monitoring. Although the base station 105-c may also transmit an idle control message 420 to the UE 115-e prior to the transmission opportunity 403, the UE 115-e may not detect the idle control message 420 because the idle control message 420 may be configured for 30kHz SCS communications, while the UE 115-e may be configured for 15kHz SCS communications. After slot-level monitoring, the UE 115-e may detect 15kHz SCS communications during slots configured for 15kHz SCS downlink burst transmissions, such as in monitoring period 435, monitoring period 440, monitoring period 445, and monitoring period 450. After the duration of transmission opportunity 403, the UE 115-e may then return to mini-slot-level monitoring.

[0104] The second UE 115-f may also first monitor at the mini-slot level until the monitoring period. Prior to the transmission opportunity 403, and in the monitoring period 455, the UE 115-f may receive an idle control message 420 from the base station 105-c. The idle control message may indicate the duration of the silent COT of the associated SCS (here 30kHz) (shown as the remaining COT duration 460). Based on the idle control message 420, the UE 115-f may stop monitoring until the end of the current transmission opportunity 403 according to the remaining COT duration 460 signaled in the idle control message 420. After the remaining COT duration 460 and the transmission opportunity 403, the UE 115-f may then return to mini-slot level monitoring. Additionally or alternatively, the idle control message 420 may include a bitmap indicating whether the corresponding SCS will be served within each time slot 405 of the remaining COT duration 460. Thus, UE 115-f may monitor time slot 405 for the remaining COT duration 460, as given by the corresponding indication in the bitmap of the corresponding SCS for UE 115-f.

[0105] In some implementations, such as reference Figures 2 to 4In any of the above, the base station 105 can communicate with the UE 115 using a directional beam to communicate with the served UE 115. That is, the base station 105 can use beams in different beam directions to communicate with the served UEs 115 in different physical locations. Therefore, for a particular transmission opportunity, in a similar manner as described for different SCSs, the base station 105 can use a first beam direction to transmit a control message to one or more UEs 115 in the serving cell, and the UE 115 in a different second direction may not receive the control transmission. As described with reference to Figures 2 to 4 Similar to what is described for different SCSs, a UE 115 that receives a control message may switch from mini-slot level monitoring to slot level monitoring for a corresponding transmission opportunity, whereas a UE 115 that does not receive a control message may not switch from mini-slot level monitoring to slot level monitoring.

[0106] Thus, in addition to or in lieu of the SCS-dependent control messages described herein, in some cases, the base station 105 may transmit a control message (e.g., a COT-SI message) in each beam direction of a UE 115 served or to be served by the base station 105 during a corresponding transmission opportunity. In some cases, the control message may be an idle control message (e.g., as described with reference to Figure 4 ), and the base station 105 may transmit an idle control message (e.g., an idle COT-SI message) in each beam direction of a UE 115 not served by the base station 105 during a corresponding transmission opportunity.

[0107] In some cases, the base station 105 may include a bitmap of beam indices in the idle control message, where each bit of the bitmap may indicate whether the corresponding beam direction will be served in the corresponding transmission opportunity. In some cases, different UEs 115 may be physically close enough to each other that a UE 115 that is not intended to receive a message transmitted in a particular direction may still receive the transmitted message due to proximity to the corresponding UE 115 in the beam direction (e.g., the beamforming for a directional beam may not be sharp enough to completely invalidate other UEs 115 near the intended target UE 115). Therefore, by including a bitmap of beam indices in the control message, the base station 105 may explicitly indicate the beam direction of each UE 115 and whether the beam direction associated with a given UE 115 will be served in the corresponding transmission opportunity. In some cases, the base station 105 may transmit a control message that includes a bitmap of beam indices in all directions, which may cause the unserved UE 115 to stop monitoring for the duration of the corresponding transmission opportunity, thereby saving power at the unserved UE 115. In some cases, as similarly described herein with respect to different SCSs, the control message may indicate an additional silence duration after the transmission opportunity (or, alternatively, a total silence duration instead of the duration of the transmission opportunity) during which the unserved UE 115 is to remain silent (e.g., in a case where the base station 105 knows that the base station 105 will not transmit downlink communications to the UE 115 in a particular beam direction for an extended period of time).

[0108] In some implementations (e.g., in a wireless communication system implementing unlicensed band communications, such as NR-Unlicensed (NR-U)), an anchor carrier (e.g., in a licensed band) may be used to provide information to one or more UEs 115 indicating an SCS and / or beam index and an associated time duration (e.g., a transmission opportunity and / or an additional amount of time or a total amount of time). According to some aspects, a transmission on the anchor carrier may include a bitmap indicating whether the SCS and / or beam index will be served for a corresponding transmission opportunity (and / or may include a corresponding silence duration for the next COT and one or more subsequent COTs). Thus, in some cases, a UE 115 for each different SCS and each different beam direction may receive information indicating whether the UE 115 will be served, and a UE 115 that is not served may stop monitoring downlink communications, thereby saving power, until the associated transmission opportunity and / or silence period ends.

[0109] Figure 5 Illustrate aspects of a transmission timeline 500 that supports techniques for configuring multiple SCSs and multiple beam direction communications in accordance with aspects of the present disclosure. In some aspects, the transmission timeline 500 may be implemented as described with reference to Figure 1Aspects of the wireless communication system 100 are described. The transmission timeline 500 shows a first transmission timeline 500-a and a second transmission timeline 500-b, each transmission timeline including a base station and one or more UEs in a serving cell of the base station (which may be as described in reference to Figure 1 Time resources are allocated for different types of communications between corresponding devices (examples described). Figure 5 The transmission timeline 500 of illustrative aspects, wherein a base station may transmit a signal (e.g., a reference signal and / or a wake-up signal) to one or more UEs that identifies an upcoming downlink transmission burst to the UEs. In addition, while the communication procedures described herein may be described with reference to different SCSs, it should be understood that similar procedures may be similarly used for different beam directions, as discussed herein.

[0110] In some cases, a first SCS (e.g., a 15kHz SCS) may be served in the current COT (e.g., only the first SCS may be served, while the second SCS or other SCSs may not be served). In this case, the base station may transmit one or more reference signals for the first SCS in the COT, wherein the reference signal may indicate the downlink transmission burst for the SCS in the COT to the served UE (e.g., a UE configured to communicate using the first SCS). In this way, a UE that is not served (e.g., a UE configured to communicate using a second SCS (e.g., a 30kHz SCS)) may not be able to detect the start of the COT. Alternatively, the base station may also transmit one or more reference signals to the UE that is not served, which, in some cases, may indicate that the UE that is not served is to switch from mini-slot level monitoring to slot level monitoring to save power. In this case, the base station may further transmit a control message (e.g., a COT-SI message, an idle COT-SI message, etc.) to the unserved UE to indicate to the unserved UE the time when the unserved UE can switch back to mini-slot level monitoring for other subsequent communications.

[0111] Alternatively, multiple SCSs may support the current COT (eg, the COT may include communications with UEs configured to communicate using a 15 kHz SCS and UEs configured to communicate using a 30 kHz SCS). Transmission timeline 500 illustrates an example of such a scenario in which multiple SCSs are supported.

[0112] Figure 5The first transmission timeline 500 shows five time slots configured for communication with the UE, including a first time slot 505, a second time slot 510, a third time slot 515, a fourth time slot 520, and a fifth time slot 525. As shown by the first transmission timeline 500-a, the first time slot 505, the third time slot 515, and the fourth time slot 520 may be configured to communicate with the UE using a first SCS (such as 15kHz). Also as shown by the first transmission timeline 500-a, the second time slot 510 and the fifth time slot 525 may be configured to communicate with the UE using a second SCS (such as 30kHz). In some cases, the base station may transmit a reference signal (e.g., a wideband DMRS) to each UE of the served SCS.

[0113] According to some aspects, at the beginning of a first time slot 505 configured for communicating with a UE using a first SCS, the base station may transmit a first reference signal 530 (e.g., a wideband DMRS, e.g., using a 15kHz SCS) to the corresponding UE. The first reference signal 530 may indicate to the UE configured for communicating using the first SCS that the base station will transmit downlink transmission bursts in the first time slot 505, the third time slot 515, and the fourth time slot 520 using the first SCS. Based on the first reference signal 530, the UE may monitor downlink transmissions during these time slots. Similarly, at the beginning of a second time slot 510 configured for communicating with a UE using a second SCS, the base station may transmit a second reference signal 535 (e.g., a wideband DMRS, e.g., using a 30kHz SCS) to the corresponding UE. The second reference signal 535 may indicate to the UE configured for communicating using the second SCS that the base station will transmit downlink transmission bursts in the second time slot 510 and the fifth time slot 525 using the second SCS. Based on the second reference signal 535, the UE may monitor downlink transmissions during these time slots.

[0114] Additionally or alternatively, such as Figure 5 As shown in the second transmission timeline 500 of FIG. 5 , five time slots may be configured for communicating with a UE, including a first time slot 505, a second time slot 510, a third time slot 515, a fourth time slot 520, and a fifth time slot 525. As shown by the second transmission timeline 500-b, each of the first time slot 505, the second time slot 510, the third time slot 515, and the fourth time slot 520 may be configured for communicating with the UE using a first SCS (such as 15kHz). Also as shown by the second transmission timeline 500-a, the fifth time slot 525 may be configured for communicating with the UE using a second SCS (such as 30kHz). In some cases, the base station may transmit a wake-up signal to all UEs (e.g., UEs configured to communicate using the first SCS and UEs configured to communicate using the second SCS) before downlink communication begins.

[0115] According to some aspects, before the start of the first time slot 550 configured for downlink communication, the base station may transmit a wake-up signal 580 using a first SCS to wake up the UE configured to communicate using the first SCS. The base station may further transmit a wake-up signal 585 using a second SCS to wake up the UE configured to communicate using the second SCS before the start of the first time slot 550 configured for downlink communication. The wake-up signal may indicate that the UE is to start monitoring downlink transmissions. In some cases, the wake-up signal may not include duration information. Therefore, at some point during the transmission opportunity, the base station may transmit further signaling to the UE (e.g., COT-SI, information carried on the anchor carrier, etc.), which further signaling includes the duration for which the UE is to monitor the transmission (e.g., the wake-up signal monitoring period).

[0116] Additionally or alternatively, the base station may transmit a common preamble (e.g., a time domain preamble) to a UE of a serving cell of the base station to indicate information for an upcoming downlink communication with the base station. That is, before a downlink transmission burst begins, the base station may transmit a common time domain preamble using each SCS that the UE served by the base station may be configured to communicate with. The preamble may be independent of the SCS and may be a fixed time domain waveform such that the preamble may be detected by a UE configured to communicate using any SCS. According to some aspects, the base station may transmit such a periodic waveform (e.g., with a period of 8.33 microseconds) on every second or fourth frequency tone (e.g., for 30 and 15kHz SCSs, respectively). The UE may detect the preamble and change the PDCCH monitoring level based on the preamble detection, such as from mini-slot level monitoring to slot level monitoring, and thus power savings may be achieved from relatively less frequent monitoring. Additionally or alternatively, the SCS detected by the UE based on the preamble (e.g., according to the pattern or content of the preamble) may indicate to the UE to stop monitoring transmissions during the COT (e.g., based on the SCS for which the UE is configured being different from the detected SCS). In some cases, the preamble may further include information indicating the remaining duration and / or total duration of the COT.

[0117] In some cases, the base station may transmit different periodic preamble patterns for different SCSs. That is, the base station may transmit a preamble using a first pattern for a first SCS (e.g., for a 15kHz SCS), and may transmit a preamble using a second pattern for a second SCS (e.g., for a 30kHz SCS). Therefore, a UE receiving a preamble may identify the associated SCS based on the pattern of the preamble. In some cases, the base station may periodically transmit a preamble using a first period (e.g., 8.33 microseconds) when serving a first SCS (e.g., 15kHz), and may periodically transmit a preamble using a second period (e.g., 16.66 microseconds) when serving a second SCS (e.g., 30kHz). In some cases, the base station may periodically transmit a preamble using one period (e.g., 8.33 microseconds) when serving each SCS, but may use different transmission modes corresponding to different SCSs (e.g., using different sets of time, frequency, and / or space resources).

[0118] Additionally or alternatively, the transmitted preamble may use a first SCS (e.g., 15kHz), and the alternating frequency modulation may carry a payload including additional content. In some cases, UEs operating according to different SCSs (e.g., both UEs configured to communicate using 15kHz SCS and 30kHz SCS) may decode the contents of the payload (such as with CRC protection). The payload may include one or more of the following: a set of SCSs for UEs or for UEs to be served in the current transmission opportunity; whether UEs not being served may be turned off for a duration, and the length of the duration; the duration of the current COT (e.g., the total duration and / or the remaining duration); the COT structure (e.g., whether the codeword is uplink or downlink, the pause duration, etc.); a cell identifier; an indication of a cell group uplink random access channel (RACH) procedure that may be allowed in the COT; a trigger of a RACH procedure or other grant (e.g., other two-stage grant); and other similar information.

[0119] Figure 6 600 in accordance with various aspects of the present disclosure to support the process flow for configuring multiple SCS and multiple beam direction communication technology. In some aspects, the process flow 600 can be as referenced Figure 1 The process flow 600 may include a base station 105-d and a UE 115-g, which may be referenced Figure 1 Examples of corresponding devices described. The following alternative examples can be implemented, in which some steps are performed in a different order than described or not performed at all. In some cases, each step may include additional features not mentioned below, or further steps may be added.

[0120] At 605, the UE 115-g may identify service parameters configured for the UE 115-g for a carrier associated with the shared radio frequency channel. The service parameters may include an SCS configured for the UE 115-g for the carrier and / or a beam configured for the UE 115-g for the carrier.

[0121] At 610, the base station 105-d may determine, for each UE 115 in a set of UEs 115 served by the base station 105d via a carrier associated with a shared radio frequency channel, a service parameter from among a number of service parameters configured for each UE for communicating via the carrier. In some cases, the determined service parameters may similarly include an SCS configured for the carrier for the UE 115-g and / or a beam configured for the carrier for the UE 115-g.

[0122] At 615, the base station 105-d may perform a channel access procedure to acquire a COT for the shared radio frequency channel.

[0123] At 620, the base station 105-d may transmit a signal to the UE 115-g according to the service parameters, and the UE 115-g may receive the signal from the base station 105-d according to the service parameters. In some cases, the signal may include a common PDCCH, a COT-SI message, or a UE-specific control channel that the UE 115-g may detect in some cases when using mini-slot level monitoring. Additionally or alternatively, the signal may include one or more of a wake-up signal, a DMRS, and / or a channel state information reference signal (CSI-RS).

[0124] At 625, the base station 105-d may transmit a control message associated with a COT, which is acquired by the base station 105-d for the shared radio frequency channel via the channel access procedure performed at 615 in some cases. The UE 115-g may receive the control message (e.g., during mini-slot level monitoring). The control message may include an indication of a service associated with a service parameter via the carrier within the COT. The control message may be transmitted via a common downlink control channel and may be a COT-SI message. Alternatively, the control message may be transmitted via a control channel that is specific to the UE. In some cases, the control message may include an indication of the total duration of the COT, an indication of the remaining duration of the COT, and / or an indication of the starting point of the COT. In some cases, the control message may include an indication of a duration associated with a service associated with a service parameter that is not present. In some cases, the carrier may include a first carrier, and the UE 115-g may receive the control message via a second carrier, wherein the second carrier may be associated with a licensed radio frequency channel.

[0125] In some cases, the indication of the service associated with the service parameter may include a bitmap including a number of bits corresponding to a number of corresponding time slots of the COT, and each of the number of bits may indicate whether a corresponding time slot in the number of corresponding time slots includes the service associated with the service parameter. In some cases, the indication of the service associated with the service parameter may include a bitmap including a number of bits corresponding to a number of beams, and each of the number of bits may indicate whether a corresponding beam in the number of beams is served by the carrier during the COT. In some cases, the indication of the service may indicate which beam is served in each time slot of the COT. In some cases, the indication of the service associated with the service parameter may include a bitmap including a number of bits corresponding to a number of SCSs, and each of the number of bits may indicate whether a corresponding SCS in the number of SCSs is served by the carrier during the COT.

[0126] At 630, the UE 115-g may adapt monitoring of a control channel associated with the carrier during the COT based on a received signal, such as the signal received at 620 or the control message received at 625. In some cases, the UE 115-g may adapt monitoring of the control channel prior to receiving the control message (e.g., based on receiving the signal at 620), and the UE 115-g may receive the control message based on the adapted monitoring of the control channel.

[0127] At 635, UE 115-g may determine one or more communication parameters for communicating with base station 105-d during the COT (e.g., a monitoring level of the PDCCH, a starting time slot of the COT) based on an indication of a service associated with the service parameter, which indication may have been received from base station 105-d at 630.

[0128] In some cases, the indication of the service associated with the service parameter (as may have been received at 630) may indicate that the service associated with the service parameter does not exist during the COT. In such cases, the UE 115-g may suppress monitoring of the control channel associated with the carrier during the COT based on the indicated absence of the service associated with the service parameter during the COT. Alternatively, the indication of the service associated with the service parameter (as may have been received at 630) may indicate that the service associated with the service parameter exists during the COT. In such cases, the UE 115-g may adapt monitoring of the control channel associated with the carrier during the COT based on the indicated presence of the service associated with the service parameter during the COT. In some cases, the UE 115-g may further adapt monitoring of the control channel associated with the carrier after the COT (in some cases, based on the total duration of the COT).

[0129] At 640 , the UE 115 - g and the base station may communicate with the base station during the COT based on an indication of the service associated with the service parameters.

[0130] Figure 7 A block diagram 700 of a device 705 supporting techniques for configuring multiple SCS and multiple beam direction communications according to aspects of the present disclosure is shown. The device 705 may include aspects of the UE 115 as described herein. The device 705 may include a receiver 710, a communication manager 715, and a transmitter 720. The device 705 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0131] The receiver 710 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to techniques for configuring multiple SCSs and multiple beam direction communications, etc.). The information may be passed to other components of the device 705. The receiver 710 may include reference Fig.10 Aspects of transceiver 1020 are described. Receiver 710 may utilize a single antenna or a collection of antennas.

[0132] The communication manager 715 may identify a service parameter configured for the UE for a carrier associated with a shared radio frequency channel; receive a control message associated with a COT acquired by the base station for the shared radio frequency channel from the base station, wherein the control message includes an indication of a service associated with the service parameter via the carrier within the COT; and determine one or more communication parameters for communicating with the base station during the COT based on the indication. The communication manager 715 may include aspects of the communication manager 1010 described herein.

[0133] The communication manager 715 or its subcomponents may be implemented in hardware, in code (e.g., software or firmware) executed by a processor, or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 715 or its subcomponents may be performed by a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described in the present disclosure.

[0134] The communication manager 715 or its subcomponents may be physically located at various locations, including being distributed such that portions of functionality are implemented by one or more physical components at different physical locations. In some aspects, according to various aspects of the present disclosure, the communication manager 715 or its subcomponents may be separate and distinct components. In some aspects, according to various aspects of the present disclosure, the communication manager 715 or its subcomponents may be combined with one or more other hardware components (including, but not limited to, input / output (I / O) components, a transceiver, a network server, another computing device, one or more other components described in the present disclosure, or a combination thereof).

[0135] The actions performed by the communication manager 715 described herein may be implemented to achieve one or more potential advantages discussed herein. In some cases, the UE may receive control information from the base station via a control message communicated via one or more directional beams. Additionally or alternatively, the UE may receive a control message (e.g., an idle COT-SI message) from the base station, wherein the control message may indicate to one or more of the UEs that the SCS and / or beam index of the UE may not be served during the associated transmission opportunity.
