A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message associated with scheduling transmissions for the UE on multiple component carriers. The UE may determine, for at least a first component carrier among the multiple component carriers, that a frequency resource allocation field of the DCI message includes an indication of an invalid value for a frequency resource allocation on the first component carrier. The UE may determine, based on the invalid indication and using a subset of fields of the DCI message corresponding to the first component carrier, that one or more component carriers among the multiple CC component carriers are dormant.

Description

Technical Field

[0001] The following relates generally to wireless communications, and more particularly, to secondary cell dormancy indication for scheduling multiple component carriers. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems can 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 (e.g., long term evolution (LTE) systems, improved LTE (LTE-A) systems or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may use 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 spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices (which may be further referred to as user equipment (UE)). Summary of the invention

[0003] The described technology relates to improved methods, systems, devices and apparatuses for supporting secondary cell sleep indication for scheduling multiple component carriers. In summary, the described technology provides various mechanisms for physical downlink control channel (PDCCH) enhancements for cross-carrier scheduling. Various aspects of the described technology utilize a downlink control information (DCI) message that indicates secondary cell (SCell) sleep information, for example, sleep information for a component carrier (CC) associated with the SCell. For example, a base station may determine or otherwise identify that a CC in a plurality of CCs is dormant for a UE. Therefore, the base station may configure a frequency resource allocation field (e.g., a frequency domain resource allocation (FDRA) field) of the DCI message to indicate a value that is invalid for frequency resource allocation on at least a first CC in a plurality of CCs, for example, a value or sequence that cannot be used to schedule frequency resources for the first CC in other ways. The base station may also configure a subset of fields of the DCI message to convey or otherwise indicate information associated with a dormant CC (e.g., information identifying a dormant CC in a plurality of CCs). The base station may send a DCI message to a UE, and the UE determines that the frequency resource allocation field indicates a value that is invalid for frequency resource allocation. Based on the invalid indication, the UE may determine or otherwise identify a dormant CC among the multiple CCs. For example, the UE may determine that the DCI message indicates a dormant CC based on the invalid indication, and identify which CC(s) are dormant based on information included in a field subset (e.g., such as a modulation and coding scheme (MCS) field, a new data indicator (NDI) field, a redundancy version (RV) field, a hybrid automatic repeat / request (HARQ) field, an antenna port (AP) field, etc.).

[0004] Additionally or alternatively, aspects of the described technology support utilizing the frequency resource allocation field (and, in some examples, a subset of other fields) of a DCI message to indicate activation / release of semi-persistent resources (e.g., semi-persistent scheduling (SPS) resources and / or configured grant (CG) resources) configured for a UE. For example, a base station may use multiple CCs to send or otherwise transmit an indication of the configuration of semi-persistent resources for a UE. The base station may determine an activation state for the semi-persistent resources, and therefore, configure a frequency resource allocation field (e.g., an FDRA field) for at least a first CC of the multiple CCs to indicate an invalid value for frequency resource allocation on the first CC. Thus, the base station may send or otherwise transmit a DCI message indicating an invalid value for frequency resource allocation to the UE. The UE may receive the DCI message and determine that it indicates an invalid value for frequency resource allocation. Thus, the UE may determine the activation state for the semi-persistent resources based on the invalid indication. For example, the NDI field in the DCI message may be set to "0" and the FDRA field may indicate an invalid value, which may signal the UE that the DCI is for SPS / CG activation / release. The HARQ process number field, the RV field, etc. in the DCI message may include information associated with the activated / released semi-persistent resources, for example, identification information.

The method may include: receiving from a base station a DCI message associated with scheduling transmissions for the UE on a set of CCs; determining, for at least a first CC in the set of CCs, that a frequency resource allocation field of the DCI message includes an indication of an invalid value for a frequency resource allocation on the first CC; and determining, based on the invalid indication and using a subset of fields of the DCI message corresponding to the first CC, that one or more CCs in the set of CCs are dormant.

[0076] A wireless communication system may use grants, such as downlink control information (DCI) grants, to schedule transmissions for a user equipment (UE) on multiple component carriers (CCs). For example, a wireless communication system may include a primary cell (PCell) that uses a dynamic spectrum sharing (DSS) carrier that utilizes a 15kHz subcarrier spacing (SCS), while a secondary cell (SCell) uses a non-DSS carrier that utilizes a 30kHz or 15kHz SCS (although the described techniques are not limited to these SCS combinations). DCI grants may be sent from a carrier and schedule transmissions for the UE on a DSS carrier of the PCell and schedule transmissions for the UE on a non-DSS carrier of the SCell. However, improvements at the scheduling entity may be achieved by sending grants on a carrier that schedule transmissions for the UE on a DSS carrier associated with the PCell and a non-DSS carrier associated with the SCell. This may be beneficial, for example, because a single DCI is used to schedule data on multiple carriers, rather than using multiple DCIs.

[0077] Various aspects of the present disclosure are first described in the context of a wireless communication system. In summary, the described techniques provide various mechanisms for physical downlink control channel (PDCCH) enhancements for multi-CC scheduling. Various aspects of the described techniques utilize a DCI message (e.g., a DCI message) that indicates secondary cell (SCell) sleep information, such as sleep information for a CC associated with the SCell. For example, a base station may determine or otherwise identify that a CC in a plurality of CCs is dormant for a UE. Therefore, the base station may configure a frequency resource allocation field (e.g., a frequency domain resource allocation (FDRA) field) of the DCI message to indicate an invalid value for frequency resource allocation on at least a first CC in a plurality of CCs, such as a value or sequence that is not available for scheduling frequency resources for the first CC. The base station may also configure a subset of fields of the DCI message to convey or otherwise indicate information associated with a dormant CC (e.g., information identifying a dormant CC in a plurality of CCs). The base station may send a DCI message to a UE, and the UE determines that the frequency resource allocation field indicates an invalid value for frequency resource allocation. Based on the invalid indication, the UE may determine or otherwise identify a dormant CC in a plurality of CCs. For example, the UE may determine, based on the invalid indication, that the DCI message indicates a dormant CC, and identify which CC(s) are dormant based on information included in a field subset (e.g., such as a modulation and coding scheme (MCS) field, a new data indicator (NDI) field, a redundancy version (RV) field, a hybrid automatic repeat / request (HARQ) field, an antenna port (AP) field, etc.).

[0078] Additionally or alternatively, aspects of the described technology support utilizing the frequency resource allocation field (and, in some examples, a subset of other fields) of a DCI message to indicate activation / release of semi-persistent resources (e.g., semi-persistent scheduling (SPS) resources and / or configured grant (CG) resources) configured for a UE. For example, a base station may use multiple CCs to send or otherwise transmit an indication of the configuration of semi-persistent resources for a UE. The base station may determine an activation state for the semi-persistent resources, and therefore, configure a frequency resource allocation field (e.g., an FDRA field) for at least a first CC of the multiple CCs to indicate a value that is invalid for frequency resource allocation on the first CC. Thus, the base station may send or otherwise transmit a DCI message to the UE indicating a value that is invalid for frequency resource allocation. The UE may receive the DCI message and determine that it indicates a value that is invalid for frequency resource allocation. Thus, the UE may determine the activation state for the semi-persistent resources based on the invalid indication. For example, the NDI field in the DCI message may be set to "0" and the FDRA field may indicate an invalid value, which may signal the UE that the DCI is for SPS / CG activation / release. The HARQ process number field, the RV field, etc. in the DCI message may include information associated with the activated / released semi-persistent resources, for example, identification information.

[0079] Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams relating to secondary cell dormancy indication for scheduling multiple component carriers.

[0080] Figure 1 An example of a wireless communication system 100 supporting secondary cell dormancy indication for scheduling multiple component carriers according to various aspects of the present disclosure is shown. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-APro network, or a new radio (NR) network. In some examples, 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, or any combination thereof.

[0081] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100, and may be devices of different forms or capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which UEs 115 and base stations 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographic area over which base stations 105 and UEs 115 may support transmission of signals according to one or more radio access technologies.

[0082] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. UEs 115 may be devices of different forms or with different capabilities. Figure 1 Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein can communicate with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as Figure 1 shown.

[0083] The base stations 105 may communicate with the core network 130, or communicate with each other, or perform both operations. For example, the base stations 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) on the backhaul links 120 (e.g., via X2, Xn or other interfaces), or communicate with each other indirectly (e.g., via the core network 130), or perform both operations. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0084] One or more of the base stations 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, 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 appropriate terminology.

[0085] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other appropriate terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. UE 115 may also include or may be referred to as 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 examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various items such as appliances, or vehicles, meters, and among other examples.

[0086] The UE 115 described herein is capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, such as Figure 1 shown.

[0087] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-APro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating operations for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0088] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be placed according to a channel grid to be discovered by a UE 115. A carrier may operate in a standalone mode, where a UE 115 performs initial acquisition and connection via a carrier, or a carrier may operate in a non-standalone mode, where a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0089] The communication 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. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0090] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, 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 one of a number of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). A device of the wireless communication system 100 (e.g., a base station 105, a UE 115, or both) 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 examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0091] The signal waveform transmitted on the carrier may be composed of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, wherein the symbol period and the subcarrier spacing 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, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate for the UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communication with the UE 115.

[0092] One or more numerologies for a carrier may be supported, where the numerologies may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different numerologies. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0093] The basic time unit (which may be referred to as T s =1 / (Δf max ·N f ) seconds sampling period, where Δf max It can represent the maximum supported subcarrier spacing, and N f The time intervals for the base station 105 or the UE 115 may be expressed as multiples of a maximum supported discrete Fourier transform (DFT) size). The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0094] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of a cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0095] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in the form of bursts of shortened TTIs (sTTIs)).

[0096] Physical channels may be multiplexed on a carrier according to various techniques. For example, one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique may be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by the number of symbol periods and may extend across the system bandwidth of a carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates with one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0097] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity used to communicate with the base station 105 (e.g., on a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID) or other identifier) ​​for distinguishing adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), the range of such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping geographic coverage areas 110, as well as other examples.

[0098] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 115 with a service subscription to a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 than a macro cell, and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to a UE 115 with a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a residence or office). A base station 105 may support one or more cells, and may also support the use of one or more component carriers to communicate on one or more cells.

[0099] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0100] In some examples, base stations 105 may be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for respective geographic coverage areas 110 using the same or different radio access technologies.

[0101] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0102] Some UEs 115 (e.g., 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 base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a human interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0103] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UE 115 include entering a power-saving deep sleep mode when not participating in active communications, when operating on a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0104] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication, and can be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably in this article.

[0105] In some examples, UE 115 is able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0106] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicle can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicle can use signals to send information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, the vehicle in the V2X system can communicate with roadside infrastructure (such as a roadside unit), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both operations.

[0107] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connection, and other access, routing or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function unit (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function unit (UPF)) for routing packets to an external network or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the core network 130. User IP packets may be transmitted through a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0108] Some of the network devices (e.g., base stations 105) may include subcomponents such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145 (which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0109] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures for macro cells to provide service to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0110] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as a centimeter band) or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and 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 examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ according to countries or regulatory agencies.

[0111] The wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) can employ carrier sensing for conflict detection and avoidance. In some examples, operations in unlicensed bands can be based on a carrier aggregation configuration in combination with component carriers operating in a licensed band (e.g., LAA). Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, as well as other examples.

[0112] The base station 105 or UE 115 may be equipped with multiple antennas, which may be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operations or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, 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 a number of 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. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals sent via the antenna ports.

[0113] The base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technology may be referred to as spatial multiplexing. For example, a transmitting device may send multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the 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 (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0114] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to form or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating in a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements may be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0115] As part of the beamforming operation, the base station 105 or the UE 115 may use beam scanning techniques. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communications with the UE 115. The base station 105 may send some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 may send signals based on different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or by a receiving device (such as the UE 115)) to identify a beam direction for subsequent transmission or reception by the base station 105.

[0116] Base station 105 may transmit some signals (e.g., data signals associated with a particular receiving device (e.g., UE 115)) in a single beam direction (e.g., a direction associated with the receiving device). In some examples, the beam direction associated with transmission along the single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 having the highest signal quality or otherwise acceptable signal quality.

[0117] In some examples, transmissions by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may generate a combined beam for transmission (e.g., from the base station 105 to the UE 115) using a combination of digital precoding or radio frequency beamforming. The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may be precoded or not precoded. The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type of codebook, a linear combination type of codebook, a port selection type of codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to send signals in a single direction (e.g., to send data to a receiving device).

[0118] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from the base station 105, the receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different reception beamforming weight sets applied to the signals received at multiple antenna elements of the antenna array (e.g., different directional listening weight sets), or by processing the received signals according to different reception beamforming weight sets applied to the signals received at multiple antenna elements of the antenna array (any of the above operations may be referred to as "listening" according to different reception configurations or reception directions). In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0119] The wireless communication system 100 may be a packet-based network operated according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to transmit on a logical channel. The medium access control (MAC) layer may perform priority handling and multiplexing of logical channels to transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection (which supports radio bearers for user plane data) between a UE 115 and a base station 105 or a core network 130. At the physical layer, transport channels may be mapped to physical channels.

[0120] UE 115 and base station 105 can support retransmission of data to increase the possibility that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technology for increasing the possibility that data is correctly received on communication link 125. HARQ can 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 at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support the same time slot HARQ feedback, wherein the device can provide HARQ feedback for data received in the previous symbol in the time slot in a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0121] UE 115 may receive, from base station 105, a DCI message associated with scheduling transmissions for UE 115 on a plurality of component carriers. UE 115 may determine, for at least a first component carrier among the plurality of component carriers, that a frequency resource assignment field of the downlink control information message includes an indication that a value is invalid for a frequency resource assignment on the first component carrier. UE 115 may determine that one or more of the plurality of component carriers are dormant based at least in part on the invalidation indication and using a subset of fields of the DCI message corresponding to the first component carrier.

[0122] UE 115 may receive a configuration of semi-persistent resources for the UE using multiple component carriers. UE 115 may receive a downlink control information message associated with scheduling transmissions for UE 115 on multiple component carriers from base station 105. UE 115 may determine, for at least a first component carrier of the multiple component carriers, that a frequency resource allocation field of the DCI message includes an indication of an invalid value for a frequency resource allocation on the first component carrier. UE 115 may determine an activation state for the semi-persistent resources based at least in part on the invalid indication.

[0123] Base station 105 may determine, for UE 115, that one or more component carriers of the plurality of component carriers are dormant. Base station 105 may configure a frequency resource allocation field of a DCI message to indicate an invalid value for frequency resource allocation on at least a first component carrier of the plurality of component carriers, and a subset of fields of the DCI message to indicate information associated with the dormant one or more component carriers. Base station 105 may send, to UE 115, a DCI message associated with scheduling transmissions for UE 115 on the plurality of component carriers.

[0124] Base station 105 may send a configuration of semi-persistent resources for UE 115 using multiple component carriers to UE 115. Base station 105 may determine an activation state for the semi-persistent resources. Base station 105 may configure a frequency resource allocation field of a DCI message to indicate an invalid value for frequency resource allocation on the first component carrier for at least a first component carrier of the multiple component carriers and the activation state. Base station 105 may send a DCI message to UE 115 conveying an invalid indication.

[0125] Figure 2 An example of a CC configuration 200 supporting a secondary cell dormant indication for scheduling multiple component carriers according to aspects of the present disclosure is shown. In some examples, the CC configuration 200 can implement aspects of the wireless communication system 100. Aspects of the CC configuration 200 can be implemented by a base station (e.g., a PCell and / or SCell) and a UE (which can be examples of corresponding devices described herein).

[0126] A wireless communication system may use a grant, such as a DCI grant, to schedule transmissions for a UE on multiple CCs. For example, a wireless communication system may include a PCell that uses a DSS carrier that utilizes a 15kHz SCS, while a SCell uses a non-DSS carrier that utilizes a 30kHz or 15kHz SCS (although the described techniques are not limited to these SCS combinations). In some examples, a DCI grant may be sent from a carrier associated with the PCell, and transmissions for the UE are scheduled on the DSS carrier of the PCell, and transmissions for the UE are scheduled on the non-DSS carrier of the SCell. However, improvements at the scheduling entity may be achieved by sending a grant on a non-DSS carrier of the SCell, which schedules transmissions for the UE on a DSS carrier associated with the PCell and a non-DSS carrier associated with the SCell. This may be beneficial, for example, because a single DCI is used for cross-carrier scheduling, rather than using multiple DCIs.

[0127] For example, a scenario may include a PCell (or another SCell) being associated with a 15kHz DSS carrier, and a SCell being associated with a 30kHz non-DSS carrier or some other carrier type / SCS. The PCell typically has uplink resources available, while the SCell may not have uplink resources available (e.g., the SCell is configured for downlink-only carrier aggregation). In a non-limiting example, both the PCell and the SCell may operate in frequency range 1 (FR1). In a non-limiting example, the SCell may be associated with a NR unlicensed (NR-U) carrier.

[0128] Aspects of the described techniques include cross-carrier scheduling (CCS) from SCell to PCell. For example, DCI from the PCell PDCCH can be moved to the SCell PDCCH. This multi-carrier scheduling can improve operations at the PCell PDCCH using a single DCI instead of multiple DCIs (e.g., a separate DCI schedules each CC). Non-DSS carrier scenarios can also be improved according to the described techniques.

[0129] In the context of the described technology, two DCI instances may be considered. In instance one, the DCI 205 may schedule data (e.g., PDSCH 210 on the CC of the SCell and PDCCH 215 on the CC of the PCell) and provide an indication of SCell sleep (e.g., a CC associated with a dormant SCell). In instance two, the DCI may provide an indication of SCell sleep. In the case where the DCI is a DCI that schedules PDSCH on multiple CCs, the FDRA field of the DCI may be a separate field for the CC or a joint FRDA field for the CC. The MCS, NDI, and RV fields may be separate fields for the CC, while the HARQ and AP fields may be joint fields or separate fields. Aspects of the described technology may be implemented for instance two scenarios (e.g., the DCI indicates SCell sleep).

[0130] For example, if the FDRA field of the DCI indicates an invalid value for one or more CCs, the DCI may be used to indicate that the SCell is dormant. For example, a base station (e.g., in this example, the SCell) may determine that a CC associated with the UE is dormant. The UE may be configured with multiple CCs or CC sets, but only some of the CCs are dormant. Therefore, the base station may set or otherwise configure the frequency resource allocation field (e.g., the FDRA field) of the DCI message 205 to indicate an invalid value for frequency resource allocation on at least one CC (e.g., the first CC). Broadly speaking, an invalid value for frequency resource allocation may include the FDRA field being set to all "1"s or all "0"s or being set to a value or sequence that is not associated with the frequency resource allocation. That is, the invalid indication may be any value or bit sequence (e.g., using a bitmap) that is not otherwise used for frequency resource allocation.

[0131] The base station may also set or otherwise configure a subset of fields of the DCI message 205 to indicate information associated with a dormant CC. The field subset may include, but is not limited to, a first MCS field, a first NDI field, and a first RV field associated with a first CC in the DCI message 205, and a second MCS field, a second NDI field, and a second RV field associated with a second CC in the DCI message 205, for example, separate fields. In some aspects, the field subset may include a HARQ field, and the AP (e.g., antenna port field) of the DCI message may be a joint field or a separate field. In some aspects, the field subset may be used to indicate a dormant SCell. For example, a field subset may carry or otherwise transmit information identifying a dormant SCell (e.g., a dormant CC of an SCell).

[0132] In some aspects, the field subset may include a resource allocation (RA) type field. In some aspects, the RA type field and the FDRA field may jointly indicate that the DCI message 205 signals a dormant SCell. For example, if RA type "0" is used for a CC, then setting the corresponding FDRA field to all "0"s may convey an invalid indication. In another example, if RA type "1" is used for a CC, then setting the corresponding FDRA field to all "1"s may convey an invalid indication.

[0133] If the invalid FDRA indication is for only one CC, then among the MCS, NDI, RV, HARQ, and AP fields, the field that exists specifically for that CC is used to indicate the dormant SCell. That is, separate fields such as MCS, NDI, and RV are associated with the CC corresponding to the invalid indication. If the invalid FDRA indication is for two CCs, then all MCS, NDI, RV, HARQ, and AP fields may be used to indicate the dormant SCell. Thus, the base station may send or otherwise transmit a DCI message 205 to the UE. The DCI message 205 may be configured according to the techniques discussed above.

[0134] The UE may receive a DCI message 205 from a base station and determine that a frequency resource allocation field (e.g., FDRA) indicates an invalid value for a frequency resource allocation. For example, the UE may recover (e.g., receive, successfully decode, and retrieve an entry from the FDRA field of the DCI message 205) the RA type field and the FDRA field, determine that they are both set to all "0"s or all "1"s, and determine that this indicates an invalid value. In some aspects, the UE may recover the FDRA field that is set to any value or sequence that is not otherwise associated with a frequency resource allocation, which may provide an invalid indication. Based on the invalid indication, the UE may recover information from a subset of fields (e.g., MCS, NDI, RV, HARQ, AP, etc.) to identify a dormant SCell (e.g., a dormant CC associated with the SCell).

[0135] In some examples, in addition to multi-CC scheduling, aspects of the described techniques can also be used for SPS / CG activation / release. For example, a base station can use multiple CCs to send or otherwise transmit the configuration of semi-persistent resources for a UE. The semi-persistent resources can be SPS and / or CG resources.

[0136] In some aspects, DCI message 205 can be used to activate / release such SPS / CG resources. For example, if DCI message 205 is CRC-scrambled by a cell-specific radio network temporary identifier (CS-RNTI), DCI message 205 is considered to be used for SPS / CG activation / release. For a single SPS / CG resource, in addition to the HARQ, RV, and MCS fields, whether DCI message 205 is used for activation or release can be based on the FDRA field. For multiple SPS / CG resources, the HARQ field can be used to indicate the SPS index or the CG index, and activation / release can be based on the FDRA, RV, and MCS fields. The NDI field is set to "1" to indicate that the DCI message 205 is used for activation / release, and if the DCI message 206 is scheduling retransmission, the NDI field is set to "0". That is, when multiple SPS / CGs are being configured, the HARQ process number field of the DCI message 205 can be used to indicate the SPS / CG index.

[0137] Thus, the base station may determine an activation state for the semi-persistent resources and configure the frequency resource allocation field (e.g., FDRA field) of the DCI message 205 to indicate an invalid value for frequency resource allocation on at least one CC (e.g., CC1), as discussed above. The base station may configure a subset of fields on the DCI message 205 to include information identifying a dormant SCell (e.g., CC). The base station may send the DCI message 205 to the UE, and the UE may use the DCI message 205 to identify or otherwise determine the dormant CC. That is, the UE may determine, for at least one CC (such as CC1), that the FDRA field indicates an invalid value for frequency resource allocation. Based on the invalid indication, the UE may determine an activation state for the semi-persistent resources.

[0138] In a non-limiting example where a separate FDRA field is used for a scheduled CC, this may include setting the NDI field for the CC that activates / releases the SPS / CG to "0". For an SPS / CG release indication for a CC, the FDRA field for the CC is an invalid value, and the MCS field for the CC is set to all "1's", and SPS / CG release indications for both CCs are possible by indicating an invalid FDRA value for both CCs. If the HARQ process number field is a separate field, and in the case where a single SPS / CG resource is used for a CC, the HARQ process number field and the RV field for the CC with activation / release may be set to all "0's". In the case where multiple SPS / CG resources are used for a CC, the RV field for the CC with activation / release may be set to all "0's", and the HARQ field for the CC indicates the SPS / CG index to be activated or released.

[0139] If the HARQ process number field is a joint field, the HARQ process number field should be common between CCs (e.g., set to a common or same value) regardless of whether a single SPS / CG resource or multiple SPS / CG resources are configured. For a single SPS / CG resource, the HARQ process number field and the RV field for the CC with activation / release can be set to all "0s", and the activation / release can be a common behavior for both CCs. For multiple SPS / CG resources, the HARQ process number field can indicate the same SPS index or CG index for both CCs. Activation / release for a given SPS / CG index can be a common behavior for both CCs.

[0140] In another non-limiting example of a joint FDRA field for a scheduled CC, this may include setting the NDI field for the CC that activates / releases SPS / CG to "0". The joint FDRA field may be (1) a configurable table with multiple columns for different CCs (and the DCI message 205 may indicate one of the rows of the table) or (2) contiguous resource allocations on multiple CCs, etc. For an SPS / CG release indication for a CC, the FDRA field may be set to no resources for the CC, and the MCS field for the CC may be set to all "1's". SPS / CG release indications for both CCs are possible by indicating no resources (e.g., an invalid indication) in the FDRA field for both CCs.

[0141] If the HARQ process number field is a separate field, in the case of indicating a single SPS / CG resource for a CC, the HARQ process number field and the RV field for the CC with activation / release may be set to all "0". In the case of indicating multiple SPS / CG resources for a CC, the RV field for the CC with activation / release may be set to all "0", and the HARQ process number field for the CC indicates the SPS / CG index to be activated or released.

[0142] If the HARQ process number field is a joint field, whether a single SPS / CG resource or multiple SPS / CG resources are configured may be common between CCs. For a single SPS / CG resource, the HARQ process number field and the RV field for the CC with activation / release may be set to all "0". Activation / release may be a common behavior for both CCs. For multiple SPS / CG resources, the HARQ field indicates the same SPS index or CG index for both CCs. Activation / release for a given SPS / CG index may be a common behavior for both CCs.

[0143] Therefore, the UE may determine the activation status (eg, activated / released) for the configured semi-persistent resources based on the DCI message 205 received from the base station.

[0144] Figure 3 An example of a DCI configuration 300 supporting a secondary cell dormant indication for scheduling multiple component carriers according to aspects of the present disclosure is shown. In some examples, the DCI configuration 300 can implement aspects of the wireless communication system 100 and / or CC configuration 200. Aspects of the DCI configuration 300 can be implemented by a base station (e.g., P / SCell) and / or a UE (which can be examples of corresponding devices described herein).

[0145] As described above, aspects of the described technology support SCell sleep indication with multi-CC scheduling for UE. For example, the base station may identify or otherwise determine that the SCell configured for the UE is dormant (e.g., a CC associated with the SCell). Therefore, the base station may set or otherwise configure a frequency resource allocation field (e.g., FDRA field) of a DCI message (e.g., DCI 305) to indicate an invalid value for frequency resource allocation on at least the first CC (e.g., CC1) based at least in part on dormancy. The base station may also use information associated with the dormant CC to set or otherwise configure a subset of fields of the DCI message, such as MCS, NID, RV, HARQ, AP, etc. The base station may send or otherwise transmit a DCI message (e.g., DCI 305) associated with scheduling transmissions for the UE on multiple CCs to the UE. The UE may use the DCI message to identify the dormant CC. For example, the UE may determine that the frequency resource allocation field indicates an invalid value, which may signal that the DCI message is a multi-CC scheduling DCI and includes a CC sleep indication. The UE may then decode or otherwise recover information of the subset of fields (eg, identification information) to determine which CCs are dormant.

[0146] Also as described above, the DCI message may use a separate FDRA field for each CC or a joint FDRA field for each CC. DCI configuration 300 shows an example of a DCI message using a separate FDRA field per CC. For example, DCI 305 (e.g., a DCI message) may include an FDRA field 310 (e.g., a first frequency resource allocation field) associated with a first carrier (e.g., CC1), an FDRA field 315 associated with a second carrier (e.g., CC2). If CC1 is dormant, the FDRA field 310 may be set to an invalid indication, and / or if CC2 is dormant, the FDRA field 315 may be set to an invalid indication. A value that is invalid for frequency resource allocation on a CC may be any value or sequence that is not otherwise associated with frequency resource allocation, for example, all "0", all "1", or any other value / sequence that is not otherwise configured to allocate frequency resources.

[0147] The DCI 305 may also include an MCS field 320, an NDI field 325, and an RV field 330, each of which is associated with CC1. The DCI 305 may also include an MCS field 335, an NDI field 340, and an RV field 345, each of which is associated with CC2. If the FDRA field 310 is set to or otherwise indicates a value that is invalid for frequency resource allocation on CC1, the MCS field 310, the NDI field 325, and the RV field 330 may be set to or otherwise configured with information identifying CC1 (e.g., a dormant SCell / CC). If the FDRA field 315 is set to or otherwise indicates a value that is invalid for frequency resource allocation on CC2, the MCS field 335, the NDI field 340, and the RV field 345 may be set to or otherwise configured with information identifying CC2 (e.g., a dormant SCell / CC). If both the FDRA fields 310 and 315 are set to values ​​that are invalid for frequency resource allocation, each corresponding MCS / NDI / RV field may be configured with identification information of the corresponding SCell / CC.

[0148] The DCI 305 may also include a HARQ field 350 and an AP field 355. If one of the FDRA fields is set to a value that is invalid for frequency resource allocation, the HARQ field 350 and the AP field 355 may be used for their original purpose (e.g., indicating HARQ / AP information). However, if both FDRA fields are set to values ​​that are invalid for frequency resource allocation, the HARQ field 350 and the AP field 355 may be configured with information associated with dormant CC1 and CC2. For example, the HARQ field 350 and the AP field 355 may provide the addition of additional information that identifies a dormant SCell / CC, for example, used as an additional bit to identify a dormant SCell / CC. In one example, the HARQ field 350 and the AP field 355 may be used to indicate additional information about dormancy, for example, timing information.

[0149] In some aspects, this may include: when the FDRA field 310 for CC1 indicates an invalid value, the MCS field 320 for CC1, the NDI field 325 for CC1, and the RV field 330 for CC1 provide a bitmap for each configured dormant SCell / CC. In some examples, the bitmap may be in ascending order of the SCell index. A "0" value of a bit of the bitmap may indicate an active downlink bandwidth part (BWP) for the corresponding activated SCell provided by the dormant BWP for the UE. If the current active downlink BWP is a dormant downlink BWP, a "1" value of a bit of the bitmap may indicate an active downlink BWP for the corresponding activated SCell / CC provided to the UE by the active time within the first non-dormant BWP identifier (ID) DCI. If the current active downlink BWP is not a dormant DL BWP, a "1" value of a bit of the bitmap may indicate the current active downlink BWP for the UE for the corresponding activated SCell. The UE sets the active downlink BWP to the indicated active downlink BWP.

[0150] If the FDRA field 315 for CC2 indicates an invalid value, the MCS field 335 for CC2, the NDI field 340 for CC2, and the RV field 345 for CC2 provide a bitmap for each configured SCell in ascending order of the SCell index, similar to the case where the FDRA field 310 for CC1 indicates an invalid value. If the FDRA field 310 / 315 for both CC1 and CC2 indicates an invalid value, the MCS field 320 for CC1, the NDI field 325 for CC1, the RV field 330 for CC1, the MCS field 335 for CC2, the NDI field 340 for CC2, the RV field 345 for CC2, the HARQ field 350, and the AP field 355 may provide a bitmap for each configured SCell in ascending order of the SCell index, similar to the case where the FDRA field for CC1 indicates an invalid value, for example, the joint field may be involved in the bitmap only when both CC1 and CC2 do not have a valid FDRA field value.

[0151] Therefore, the UE may receive a DCI message (eg, DCI 305 ) and identify the dormant SCell / CC using information indicated in a corresponding field.

[0152] Figure 4 An example of a DCI configuration 400 supporting a secondary cell dormant indication for scheduling multiple component carriers according to aspects of the present disclosure is shown. In some examples, the DCI configuration 400 can implement aspects of the wireless communication system 100, the CC configuration 200, and / or the DCI configuration 300. Aspects of the DCI configuration 400 can be implemented by a base station (e.g., a P / SCell) and / or a UE (which can be examples of corresponding devices described herein).

[0153] As described above, aspects of the described technology support SCell sleep indication with multi-CC scheduling for UE. For example, the base station may identify or otherwise determine that the SCell configured for the UE is dormant (e.g., a CC associated with the SCell). Therefore, the base station may set or otherwise configure a frequency resource allocation field (e.g., FDRA field) of a DCI message (e.g., DCI 405) to indicate an invalid value for frequency resource allocation on at least the first CC (e.g., CC1) based at least in part on dormancy. The base station may also use information associated with the dormant CC to set or otherwise configure a subset of fields of the DCI message, such as MCS, NID, RV, HARQ, AP, etc. The base station may send or otherwise transmit a DCI message (e.g., DCI 405) associated with scheduling transmissions for the UE on multiple CCs to the UE. The UE may use the DCI message to identify the dormant CC. For example, the UE may determine that the frequency resource allocation field indicates an invalid value, which may signal that the DCI message is a multi-CC scheduling DCI and includes a CC sleep indication. The UE may then decode or otherwise recover information of the subset of fields (eg, identification information) to determine which CCs are dormant.

[0154] Also as described above, the DCI message may use a separate FDRA field for each CC or a joint FDRA field for each CC. DCI configuration 400 shows an example of a DCI message using a joint FDRA field. For example, DCI 405 (e.g., a DCI message) may include an FDRA field 410 associated with CC1 and CC2. If CC1 and / or CC2 are dormant, the FDRA field 410 (e.g., a joint frequency resource allocation field) may be set to an invalid indication. An invalid value for frequency resource allocation on a CC may be any value or sequence that is not otherwise associated with frequency resource allocation, for example, all "0", all "1", or any other value / sequence that is not otherwise configured to allocate frequency resources.

[0155] In some aspects, the FDRA field 410 may be a configurable table with multiple columns for different CCs, where the FDRA field 410 may indicate one of the rows of the table, a continuous resource allocation on multiple CCs, etc. If the FDRA field 410 indicates that there are no resources for the CC / in the CC, the corresponding MCS, NDI, RV, HARQ, and AP (fields specific to the CC) may be used to indicate a dormant SCell / CC. If the FDRA field 410 indicates that there are no resources in / for both CCs, all MCS, NDI, RV, HARQ, and AP fields may be used to indicate a dormant SCell.

[0156] For example, the DCI 405 may also include an MCS field 420, an NDI field 425, and an RV field 430, each of which is associated with CC1. The DCI 405 may also include an MCS field 435, an NDI field 440, and an RV field 445, each of which is associated with CC2. If the FDRA field 410 is set to or otherwise indicates a value that is invalid for frequency resource allocation on CC1, the MCS field 410, the NDI field 425, and the RV field 430 may be set to or otherwise configured with information identifying CC1 (e.g., a dormant SCell / CC). If the FDRA field 410 is set to or otherwise indicates a value that is invalid for frequency resource allocation on CC2, the MCS field 435, the NDI field 440, and the RV field 445 may be set to or otherwise configured with information identifying CC2 (e.g., a dormant SCell / CC). If the FDRA field 410 is set to a value that is invalid for frequency resource allocation on CC1 and CC2, each corresponding MCS / NDI / RV field may be configured with identification information of the corresponding SCell / CC.

[0157] The DCI 405 may also include a HARQ field 450 and an AP field 455. If the FDRA field 410 is set to a value that is invalid for frequency resource allocation on CC1 or CC2, the HARQ field 450 and the AP field 455 may be used for their original purpose (e.g., indicating HARQ / AP information). However, if the FDRA field 410 is set to a value that is invalid for frequency resource allocation on CC1 and CC2, the HARQ field 450 and the AP field 455 may be configured with information associated with dormant CC1 and CC2. For example, the HARQ field 450 and the AP field 455 may provide the addition of additional information that identifies a dormant SCell / CC, for example, as an additional bit that identifies a dormant SCell / CC. In one example, the HARQ field 450 and the AP field 455 may be used to indicate additional information about dormancy, for example, timing information.

[0158] Therefore, the UE may receive a DCI message (eg, DCI 305 ) and identify the dormant SCell / CC using information indicated in a corresponding field.

[0159] Figure 5 An example of a process 500 for supporting a secondary cell dormancy indication for scheduling multiple component carriers according to aspects of the present disclosure is shown. In some examples, the process 500 can implement aspects of the wireless communication system 100, CC configuration 200, and / or DCI configuration 300 and / or 400. Aspects of the process 500 can be implemented by a UE 505 and / or a base station 510 (which can be examples of corresponding devices described herein).

[0160] At 515 , the base station 510 may identify or otherwise determine, for the UE 505 , one or more CCs in the plurality of CCs that are dormant.

[0161] At 520, the base station 510 may set or otherwise configure a frequency resource allocation field (e.g., a separate FDRA field or a joint FDRA field) of the DCI message to a value indicating that the frequency resource configuration on at least the first CC of the multiple CCs is invalid. The base station 510 may also set or otherwise configure a subset of fields of the DCI message that indicate information associated with one or more CCs that are dormant (e.g., an MCS field, an NDI field, an RV field, a HARQ field, an AP field, an RA type field, etc.). In some aspects, this may include setting the FDRA field to an invalid value to indicate that the DCI message indicates that the SCell / CC is dormant, and then including a subset of fields that convey identification information for the dormant SCell / CC.

[0162] In some aspects, this may include the base station 510 setting a bit in the RA type field in the DCI message to a first value (e.g., "1" or "0"). The base station 510 may set each bit in a bitmap indicated in a frequency resource allocation field associated with the first CC in the DCI message to a first value (e.g., all "1"s or all "0"s). In some aspects, the value being invalid for the frequency resource allocation on the first CC may be based at least in part on each bit in the bitmap being set to the first value, e.g., each bit in the FDRA field being set to the same value as the value set for the RA type field.

[0163] In some aspects, this may include: the base station 510 configures a subset of fields of the DCI message to indicate information identifying one or more CCs that are dormant in the plurality of CCs. The base station 510 may map each bit of the bitmap indicated in the subset of fields to a CC in the plurality of CCs. In some aspects, the value and mapping of each bit may indicate whether the CC is active or dormant.

[0164] In some aspects, this may include: the base station 510 configures the frequency resource allocation field associated with the second CC of the DCI message to indicate a value that is invalid for the frequency resource allocation on the second CC. For example, the base station 510 may set a bit in the RA type field associated with the second CC in the DCI message to a first value, and set each bit in the bitmap in the frequency resource allocation field associated with the second CC in the DCI message to a first value. In some aspects, the value that is invalid for the frequency resource allocation on the second CC may be based at least in part on each bit in the bitmap being set to the first value. The base station 510 may configure a subset of fields associated with the first CC in the DCI message (e.g., MCS / NDI / RV fields associated with CC1), a second subset of fields associated with the second CC in the DCI message (e.g., MCS / NDI / RV fields associated with CC2), and a subset of common fields in the DCI message (e.g., HARQ / AP fields) to indicate information associated with one or more CCs that are dormant in multiple CCs. The base station 510 may map each bit of the bitmap indicated in the field subset, the second field subset, and the common field subset to a CC in the plurality of CCs. In some aspects, the value and mapping of each bit may indicate whether the CC is active or dormant.

[0165] In some aspects, this may include: the base station 510 configuring the joint frequency resource allocation field to indicate that no resources are allocated to the first CC. In some aspects, the value being invalid for frequency resource allocation on the first CC may be based at least in part on the fact that no resources are allocated to the first CC. The base station 510 may configure a subset of fields of the DCI message to indicate information identifying one or more CCs that are dormant in the plurality of CCs. For example, the base station 510 may map each bit of a bitmap indicated in the subset of fields to a CC in the plurality of CCs, and set the value of each bit in the bitmap to indicate whether the CC is active or dormant.

[0167] At 530, the UE 505 may determine, for at least a first CC among the plurality of CCs, that a frequency resource allocation field of the DCI message includes an indication of a value that is invalid for frequency resource allocation on the first CC. In some aspects, this may include: the UE 505 determining that a bit in an RA type field in the DCI message is set to a first value, and determining that each bit in a bitmap indicated in a frequency resource allocation field associated with the first CC in the DCI message is set to the first value. In some aspects, the value being invalid for frequency resource allocation on the first CC may be based at least in part on each bit in the bitmap being set to the first value.

[0168] At 535, the UE 505 may determine that one or more CCs in the plurality of component carriers are dormant based at least in part on the invalidation indication and using a subset of fields of the DCI message corresponding to the first CC. For example, the UE 505 may identify one or more CCs in the plurality of CCs that are dormant based at least in part on a subset of fields of the DCI message.

[0173] In some aspects, this may include: the base station 610 configures a separate HARQ process number field in the DCI message for each CC in the plurality of CCs. For example, the base station 610 may configure each bit in the HARQ process number field and the RV field of the DCI message to indicate an activation state for a semi-persistent resource associated with the first CC. The base station 610 may set each bit in the RV field to a first value based at least in part on the activation state for the plurality of semi-persistent resources associated with the first CC. In some aspects, the identification of the plurality of semi-persistent resources may be based at least in part on the HARQ process number field.

[0175] At 630, base station 610 may send (and UE 605 may receive) a DCI message conveying an invalidation indication. In some aspects, the DCI message may include a separate frequency resource allocation field for each CC in the plurality of CCs or a joint frequency resource allocation field for the plurality of CCs.

[0177] At 640, UE 605 may determine an activation state for the semi-persistent resource based at least in part on the invalid indication. For example, UE 605 may determine that the DCI message includes a separate HARQ process number field for each CC in the plurality of CCs. UE 605 may determine an activation state for the semi-persistent resource associated with the first CC based at least in part on each bit in the HARQ process number field and the RV field being set to a first value. UE 605 may determine an activation state for a plurality of semi-persistent resources associated with the first CC based at least in part on each bit in the RV field being set to a first value, and identify the plurality of semi-persistent resources based at least in part on the HARQ process number field.
