Technical Field

[0003] The following generally relates to wireless communications, and more specifically, the following relates to group scheduling applications. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, 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 employ techniques 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 spectrum orthogonal frequency division multiplexing (DFT-S-OFDM).

[0005] A wireless multiple access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as user equipment (UE). Some wireless communication systems may support high reliability and low latency communication, such as ultra-reliable low latency communication (URLLC) (e.g., in industrial automation) or Internet of Things (IoT) communication. Some wireless communication systems may support scheduling of communication device groups via uplink permission-free configuration or downlink semi-persistent scheduling configuration, for example, to support high reliability and low latency communication. As the demand for communication efficiency increases, some wireless communication systems may not be able to provide satisfactory time and frequency resource allocation associated with scheduling communication device groups, and thus may not be able to support high reliability and low latency communication, etc. Therefore, improved technology is needed. Summary of the invention

[0006] The described techniques may involve configuring a communication device, which may be a user equipment (UE), to support high reliability and low latency communications. For example, the communication device may support ultra-reliable low latency communications (URLLC) or Internet of Things (IoT) communications, etc. In some examples, the described techniques may configure the communication device to receive control signaling, such as downlink control information (DCI) signaling, medium access control (MAC) control element (MAC-CE) signaling, radio resource control (RRC) signaling, etc., and the signaling may configure the communication device using multiple configured permission configurations. In some examples, the described techniques may configure the communication device to receive group common downlink control information (GC-DCI) that may correspond to multiple communication devices.

[0007] In some examples, a communication device may receive GC-DCI via a group control channel, such as a group common physical downlink control channel (GC-PDCCH). In some examples, the GC-DCI may carry a configuration indication from a plurality of configured permitted configurations related to a configured permitted configuration to be used by the communication device. Thus, the described techniques may configure a communication device to support high reliability and low latency communications, among other benefits, based on a configured permitted configuration based on a configuration indication in the GC-DCI. Thus, the described techniques may include features for improving power consumption, spectral efficiency, higher data rates, and in some examples, may facilitate improved efficiency of high reliability and low latency operations, among other benefits.

[0096] Some wireless communication systems may include one or more communication devices, such as user equipment (UE) and base stations, such as next-generation node Bs or gigabit node Bs (both of which may be referred to as gNBs) that may support multiple radio access technologies, including fourth generation (4G) systems (e.g., long term evolution (LTE) systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). In some examples, one or more communication devices may support high reliability and low latency communications, such as ultra-reliable low latency communications (URLLC) or Internet of Things (IoT) communications (e.g., industrial Internet of Things (IIoT) communications) associated with the above-mentioned example radio access technologies. Some examples of one or more communication devices (e.g., one or more base stations) may support scheduling of communication device groups (e.g., one or more UEs) for high reliability and low latency communications.

[0097] In some examples, one or more communication devices may support multiple active uplink configured permitted configurations, and multiple active downlink semi-persistent scheduling configurations. Supporting one or more of multiple active uplink configured permitted configurations or multiple active downlink semi-persistent scheduling configurations can reduce the timing for aligning resources related to transmission (e.g., uplink data), and support multiple service types (e.g., URLLC or enhanced mobile broadband (eMBB)). In some examples, because the services (e.g., data transmission) used for IoT communication may be periodic, multiple communication devices (e.g., multiple UEs) may be scheduled via an uplink permission-free configuration or a downlink semi-persistent scheduling configuration to eliminate the use of scheduling multiple communication devices via a physical downlink control channel (PDCCH) through downlink control information (DCI) signaling. That is, by scheduling multiple communication devices via an uplink permission-free configuration or a downlink semi-persistent scheduling configuration, PDCCH blocking problems can be reduced, and errors or uncertainties in IoT communications can be removed or reduced.

[0098] In some examples, one or more communication devices (e.g., one or more base stations) may support retransmissions that are configured to be permitted. One or more communication devices may support retransmissions that are configured to be permitted based on dynamic permission. For example, one or more communication devices (e.g., one or more base stations) may support one or more of the initial transmission or retransmissions that are configured to be permitted via dynamic signaling (e.g., via DCI signaling). The configured permission may include multiple uplink configured permission configurations or multiple downlink semi-persistent scheduling configurations, and the dynamic signaling may carry an indication of activating one of the multiple configurations. For example, the DCI may signal an indication of time and frequency resources associated with the retransmission. In some examples, the DCI may be a common DCI that can be shared by all communication devices (e.g., all UEs). As the demand for communication efficiency increases, some of the one or more communication devices (e.g., one or more base stations) may not be able to provide satisfactory resource allocations associated with the scheduling group of other communication devices (e.g., one or more UEs), and thus may not be able to support or provide satisfactory high reliability and low latency communications.

[0099] In order to address the above shortcomings, the described technology can configure one or more communication devices (e.g., one or more UEs) to receive control signaling, such as DCI signaling, etc., and the signaling can configure multiple configured permitted configurations to one or more communication devices. In some examples, the described technology can configure one or more communication devices to receive group common downlink control information (GC-DCI) corresponding to multiple communication devices. In some examples, one or more communication devices can receive GC-DCI via a group control channel, such as a group common PDCCH (GC-PDCCH). GC-DCI can carry a configuration indication related to a configured permitted configuration to be used by one or more communication devices from multiple configured permitted configurations. Therefore, the described technology can configure one or more communication devices to support high reliability and low latency communication according to the configured permitted configuration based on the configuration indication in the GC-DCI.

[0100] Certain aspects of the inventive subject matter described in this disclosure may be implemented to achieve one or more of the following potential advantages. The techniques employed by the described one or more communication devices may provide benefits and enhancements to the operation of the communication devices. For example, the operations performed by the described one or more communication devices may provide improvements to group scheduling applications. In some examples, the described one or more communication devices may support receiving signaling including a configuration indication related to a configured permitted configuration to be used in a plurality of configured permitted configurations, which may support improvements in power consumption, spectral efficiency, higher data rates, and in some examples, may facilitate improved efficiency of high reliability and low latency operations, among other benefits.

[0101] Various aspects of the present disclosure are first described in the context of a wireless communication system. Various aspects of the present disclosure are then illustrated and described with reference to process flows related to group scheduling. Various aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to group scheduling in a wireless communication system.

[0102] Figure 1 An example of a wireless communication system 100 supporting group scheduling applications according to aspects of the present disclosure is shown. The wireless communication system 100 may include a base station 105, a UE 115, and a core network 130. In some examples, 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, communications with low-cost and low-complexity devices, or any combination thereof.

[0103] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish communication links 125. The coverage areas 110 may be examples of geographic areas over which the base stations 105 and the UEs 115 support communication of signals according to one or more radio access technologies.

[0104] The UEs 115 may be dispersed throughout the coverage area of ​​the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. The 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 may be able to communicate with various types of devices, such as other UEs 115, base stations 105, and / 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.

[0105] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may be connected to the core network 130 via a backhaul link 120 (e.g., via S1, N2, N3, or other interface). The base stations 105 may communicate with each other via the backhaul link 120 (e.g., via X2, Xn, or other interface) directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul link 120 may be or include one or more wireless links.

[0106] 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 wireless base station, an access point, a radio transceiver, a Node B, an eNodeB (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 eNodeB, or other suitable terminology.

[0107] 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 suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. 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, a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances, vehicles, meters, etc. UE 115 described herein may be able to communicate with various types of devices, such as other UE 115 that may sometimes act as a relay, as well as base stations 105 and network devices, which include, for example, Figure 1 The macro eNB or gNB, small cell eNB or gNB, relay base station, etc. are shown.

[0108] UE 115 and base station 105 can communicate with each other wirelessly via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a collection of radio frequency spectrum resources with a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency spectrum band (e.g., bandwidth portion (BWP)) that operates according to a physical layer channel for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can 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 can use carrier aggregation or multi-carrier operation to support communication with UE 115. UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to the carrier aggregation configuration. Carrier aggregation can be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0109] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operation of 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 located according to a channel grid for discovery by a UE 115. A carrier may operate in a standalone mode, where a UE 115 may perform 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 a connection.

[0110] 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).

[0111] 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 a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of predetermined bandwidths of a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base stations 105, UEs 115, or both) may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configured to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base stations 105 and / or UEs 115 that support simultaneous communications via carriers associated with a plurality of carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0112] 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 unit may be composed of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource unit 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 units received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 may 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 also increase the data rate or data integrity used to communicate with UE 115.

[0113] One or more digital parameters of a carrier may be supported, where the digital parameters may include subcarrier spacing (Δf) and cyclic prefix. A carrier may be divided into BWPs with the same or different digital designations. In some examples, a UE 115 may be configured with multiple BWPs. In some cases, a single BWP of a carrier is active at a given time, and communications for a UE 115 may be limited to the active BWP.

[0114] The time interval of the base station 105 or the UE 115 may be expressed as a multiple of a 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 maximum supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames, each radio frame 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).

[0115] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some cases, the frame may be divided into (e.g., in the time domain) subframes, and each subframe may be further divided into multiple 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 multiple symbol periods (e.g., depending on the length of the cyclic prefix that precedes each symbol period). In some wireless communication systems 100, the time slots may be further divided into multiple mini-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0116] A subframe, slot, mini-slot, or 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 cases, 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 a burst of a shortened TTI (sTTI)).

[0117] Physical channels may be multiplexed on a carrier according to various techniques. For example, using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique, a physical control channel and a physical data channel may be multiplexed 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 a system bandwidth of a carrier or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, a UE 115 may monitor or search a 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 arranged in a cascaded manner in one or more aggregation levels. An aggregation level for a control channel candidate may refer to a plurality of control channel resources (e.g., a control channel element (CCE)) associated with coding information for a control information format having a given payload size. A search space set may include a common search space set configured to send control information to a plurality of UEs 115 and a UE-specific search space set for sending control information to a particular UE 115.

[0118] In some examples, base station 105 may send, and UE 115 may receive, control signaling that configures the set of configured granted configurations for UE 115. Additionally, via the group control channel, base station 105 may send, and UE 115 may receive, GC-DCI for multiple UEs 115. As a result, base station 105 and UE 115 may transmit data transmissions according to a configured granted configuration in the set of configured granted configurations based on a configuration indication in the GC-DCI for UE 115 indicating the configured granted configuration.

[0119] 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 various combinations thereof). The term "cell" refers to a logical communication entity used to communicate with the base station 105 (e.g., via a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may 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. Such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area, depending on various factors (e.g., the capabilities of the base station 105). For example, a cell may be or include a building, a subset of a building, an external space between or overlapping a geographic coverage area 110, and the like.

[0120] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UE 115 with a service subscription to a network provider that supports the macro cell. Compared to a macro cell, a small cell may be associated with a low-power base station 105, 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 home or office, etc.). A base station 105 may support one or more cells, and may also use one or more component carriers to support communications on one or more cells. 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), or other) that may provide access rights to different types of devices.

[0121] In some examples, base stations 105 may be mobile and thus 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 various geographic coverage areas 110 using the same or different radio access technologies.

[0122] 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 transmissions from different base stations 105 may not be aligned in time in some examples. The techniques described herein may be used for synchronous operation or asynchronous operation.

[0123] 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 examples, M2M communication or MTC may include communications from devices that integrate sensors or meters for measuring or capturing information and passing 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 or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, medical monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0124] 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 one-way communication via transmission or reception, but not simultaneously transmitting and receiving). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power saving deep sleep mode when not engaged in active communications, 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 associated with a predefined portion or range (e.g., a subcarrier or resource block (RB) set) within a carrier, within a guard band of a carrier, or outside a carrier.

[0125] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or its various combinations. For example, the wireless communication system 100 can be configured to support URLLC or mission-critical communication. UE 115 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 (e.g., mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include the priority of the service, 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.

[0126] In some cases, UE 115 is also able to communicate directly with other UEs via 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 the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be located outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105. In some cases, a group of UEs 115 communicating via D2D communication may use a 1-to-many (1:M) system in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without the involvement of the base station 105.

[0127] 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 (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 (UPF)) for routing packets or interconnections 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. The operator IP service 150 may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0128] Some network devices (e.g., base station 105) may include subcomponents (e.g., access network entity 140), which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with UE 115 through multiple 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 curtains. 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).

[0129] 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, however the waves may penetrate structures sufficiently for a macro cell to provide service to a UE 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmission using the lower frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0130] 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), which is also referred to as a millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of each device may be smaller and more closely spaced than UHF antennas. In some cases, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may suffer from greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be applied across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary by country or regulatory body.

[0131] 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) or LTE unlicensed (LTE-U) radio access technology or NR technology in an unlicensed band such as the 5 GHz Industrial, Scientific and Medical (ISM) band. When operating in an unlicensed radio frequency band, wireless devices (such as base stations 105 and UEs 115) can employ a listen-before-talk (LBT) process to ensure that the frequency channel is idle before sending data. In some cases, operations in unlicensed bands can be combined with component carriers operating in licensed bands (e.g., LAA) based on carrier aggregation configurations. Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, D2D transmissions, and the like.

[0132] 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) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located within one or more antenna arrays or antenna curtains, 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 cases, the antennas or antenna arrays associated with the base station 105 may be located at different geographic locations. The base station 105 may have an antenna array having multiple 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 curtain may support radio frequency beamforming for signals sent via the antenna ports.

[0133] The base station 105 or UE 115 can use MIMO communication to utilize 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, multiple signals may be sent by a transmitting device via different antennas or different antenna combinations. Similarly, multiple signals may be received by a receiving device via different antennas or different antenna combinations. 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) in which multiple spatial layers are sent to the same receiving device, and multi-user MIMO (MU-MIMO) in which multiple spatial layers are sent to multiple devices.

[0134] 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 or a UE 115) to shape an antenna beam or to steer 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 particular direction relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjustment of 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 these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0135] The base station 105 or the UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna curtains) 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 to identify (e.g., by a transmitting device such as the base station 105, or by a receiving device such as the UE 115) the beam direction for subsequent transmission / or reception by the base station 105.

[0136] Some signals, such as data signals associated with a particular receiving device, may be transmitted by base station 105 in a single beam direction (e.g., a direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in different beam directions. For example, 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 signal received by UE 115 with the highest signal quality, or an acceptable signal quality.

[0137] In some cases, 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 use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). 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 a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or unprecoded. 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-faceted codebook, a linear combination codebook, a port selection 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 for sending signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115), or for sending signals in a single direction (e.g., for sending data to a receiving device).

[0138] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, a receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different sets of receive beamforming weights applied to signals received at a plurality of antenna element sets of an antenna array (e.g., different sets of directional listening weights), or processing received signals according to different sets of receive beamforming weights applied to signals received at a plurality of antenna elements of an antenna array, any of which may be referred to as "listening" according to different reception configurations or reception directions. In some examples, a receiving device may 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, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0139] 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 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 communicate on a logical channel. The medium access control (MAC) layer may perform priority processing and multiplex logical channels into 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 between a UE 115 and a base station 105 or a core network 130 that supports a radio bearer for user plane data. At the physical layer, a transport channel may be mapped to a physical channel.

[0140] UE 115 and base station 105 can support retransmission of data to increase the possibility of successfully receiving the data. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the possibility of correctly receiving data through 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 of the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some cases, 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.

[0141] Figure 2 An example of a wireless communication system 200 supporting group scheduling according to aspects of the present disclosure is shown. The wireless communication system 200 may include a base station 105 and a plurality of UEs 115, which may be reference Figure 1 Examples of corresponding devices described herein. In some examples, wireless communication system 200 can implement aspects of wireless communication system 100. In some examples, UE 115 in wireless communication system 200 can support receiving signaling including a configuration indication related to a configured permitted configuration to be used in multiple configured permitted configurations. Therefore, UE 115 can support improvements in power consumption, spectral efficiency, higher data rates, and in some examples, can promote improved efficiency of high reliability and low latency operations, as well as other benefits.

[0142] The base station 105 may support downlink transmission, and one or more of the UEs 115 may support downlink reception. In some examples, the base station 105 may send a scheduling command to one or more of the UEs 115, which is used to schedule time and frequency resources for communication, such as URLLC communication or IoT communication, etc. For example, the base station 105 may send a scheduling command in the DCI via the PDCCH. In some examples, the scheduling command may be an indication of an upcoming data transmission from the base station 105 to one or more of the UEs 115. In some examples, the scheduling command may also carry additional information about the upcoming data transmission, such as the amount of data, time and frequency allocation (e.g., physical resource block (PRB) allocation), modulation scheme (e.g., quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM)), etc.

[0143] The base station 105 may then send a data transmission to one or more of the UEs 115, for example, via one or more of a downlink shared channel (DL-SCH) or a physical downlink shared channel (PDSCH). One or more of the UEs 115 may respond to the base station 105 by sending a hybrid ARQ acknowledgment to indicate whether the data transmission was correctly received. One or more of the UEs 115 may send an acknowledgment on a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH). The base station 105 may also support uplink reception, and one or more of the UEs 115 may support uplink transmission. Similarly, as in downlink transmission and reception, the base station 105 may send a scheduling grant to one or more of the UEs 115 via the PDCCH. The grant may include one or more transmission parameters for one or more UEs 115, such as transmission block size, time and frequency resource allocation, modulation scheme, and other transmission parameters.

[0144] In some examples, the base station 105 can configure multiple configured grant configurations to one or more UEs 115 to support improvements in communications, such as URLLC communications or IoT communications for one or more UEs 115. For example, the base station 105 can send control signaling that configures multiple configured grant configurations to one or more of the UEs 115. In some examples, the configured grant configurations in the multiple configured grant configurations can include one or more of the downlink configuration or the uplink configuration. Each of the multiple configured grant configurations can also have varying parameters, such as different transport block sizes, time and frequency resource allocations, modulation schemes, etc.

[0145] To schedule multiple UEs 115, base station 105 may send GC-DCI 205 to group 215 of UEs 115 via group control channel 210. In some examples, group control channel 210 may be a group common PDCCH (GC-PDCCH). In some examples, base station 105 may include a configuration indication in GC-DCI 205, which may indicate to group 215 which of a plurality of configured grant configurations to use (e.g., activate, enable) for data transmission. Base station 105 may use the configuration indication mechanism for both downlink and uplink configurations.

[0146] In some examples, the base station 105 may configure one or more downlink resource configurations to the group 215 via higher layer signaling (e.g., RRC signaling or MAC control element (CE) (MAC-CE) signaling, etc.). Additionally or alternatively, the base station 105 may configure one or more uplink resource configurations, such as multiple uplink configured grants, to the group 215. In some examples, the uplink configured grant may be an uplink type one configured grant (UL type 1CG) or an uplink type two configured grant (UL type 2CG). The base station 105 may provide one or more transmission parameters related to one or more of the uplink type one configured grants or the uplink type two configured grants to the group 215 of the UE 115 via DCI.

[0147] The base station 105 may configure one or more UEs 115 in the group 215 with a GC-PDCCH. In some examples, configuring one or more UEs 115 in the group 215 may include configuring the UE 115 with a radio network temporary identifier (RNTI), which the one or more UEs 115 may use to monitor group scheduling and receive the GC-DCI 205 via the GC-PDCCH. In some examples, the RNTI may be a default RNTI or an existing RNTI may be reused (e.g., reusing a cell-specific RNTI (CS-RNTI)). In other examples, the base station 105 may configure the UE 115 with a new RNTI. In some examples, the base station 105 may scramble the DCI payload (e.g., total length) of the GC-DCI 205 with one of the above-mentioned example RNTIs. That is, the parameter dci-PayloadSize may include the total length of the DCI payload scrambled with the above-mentioned RNTI. Thus, the UEs 115 of the group 215 may receive the GC-DCI 205 via the group control channel 210 based on one or more of a group identifier (eg, RNTI) or a payload size of the GC-DCI 205 .

[0148] In some examples, the UEs 115 in the group 215 may receive the GC-DCI 205 via the group control channel 210 based on a serving cell identifier (e.g., servingCellId), which may be related to a serving cell (e.g., associated with a base station 105) to which group scheduling may apply. This may enable the UEs 115 of the group 215 to support one or more of cross-carrier activation, cross-carrier reactivation, or cross-carrier deactivation of multiple configured permitted configurations. In some cases, one or more configured permitted configurations may be activated across carriers. This may be useful when one carrier is blocked or cannot pass a contention-based process (e.g., a listen-before-talk (LBT) process) in an unlicensed channel. In some examples, the GC-DCI 205 may include multiple DCI fields that may be mapped to different UEs 115 of the group 215 and to a configured permitted configuration to be used (e.g., activated, enabled) for data transmission in multiple configured permitted configurations. That is, the positionInDCI parameter may be defined by the (starting) position (bits) of the DCI for the UE 115 in the serving cell given by the serving cell identifier (e.g., servingCellId) within the DCI payload. The base station 105 and the UE 115 may also support interaction of the GC-DCI 205 with UE-specific DCI for one or more of initial scheduling or retransmission. Figure 3 An exemplary GC-DCI is described in further detail.

[0149] Figure 3 An example of a GC-DCI 300 supporting group scheduling applications according to aspects of the present disclosure is shown. The GC-DCI 300 may have a DCI payload 305 carrying multiple control fields (which are also referred to as DCI fields). For example, the DCI payload 305 may include a DCI field 310, a DCI field 315, a DCI field 320, and a DCI field 325. Figure 2 , the base station 105 can send downlink scheduling commands, uplink scheduling grants, and uplink control commands, etc. to the UEs 115 in the group 215 via multiple DCI fields 330. The uplink scheduling grant can include multiple configured grant configurations. In some examples, the GC-DCI 300 can have a CRC 335 attached to the DCI payload 305 to improve the reliability of the transmission and reception of the GC-DCI 300.

[0150] In some examples, the plurality of DCI fields 330 may correspond to different UEs 115 of the group 215 and to a configured grant configuration to be used (e.g., activated, enabled) for data transmission in the plurality of configured grant configurations. In some examples, the base station 105 may indicate, based on the starting position indicator, that a DCI field from the plurality of DCI fields 330 is allocated to each UE 115 in the group 215. That is, each DCI bit field may correspond to a different UE 115 from the group 215. For example, the base station 105 may indicate to the UEs 115 in the group 215 to use a DCI field 320 from the plurality of DCI fields 330 based on the starting position bit 340. The UE 115 may therefore identify the configuration indication within the GC-DCI 300 based on the starting position bit 340 corresponding to the DCI field 320. The starting position bit 340 of the DCI field 320 of the UE 115 may correspond to a serving cell given by a serving cell identifier within the DCI payload 305. Therefore, the UE 115 may decode the GC-DCI 300 corresponding to the start position bit 340 to obtain at least one transmission parameter and perform data transmission accordingly.

[0151] In some examples, the base station 105 may configure each DCI bit field of the plurality of DCI fields 330 to indicate specific information. In an example, the base station 105 may configure the plurality of DCI fields 330 to indicate that the grant configuration index is mapped to the grant configuration in the plurality of configured grant configurations. In this way, each grant configuration may have its associated grant configuration index. In some other examples, the base station 105 may also configure the plurality of DCI fields 330 to indicate one or more of time domain resource allocation (TDRA), modulation and coding scheme (MCS), etc. For example, the base station 105 may configure the plurality of DCI fields 330 with one or more of TDRA, MCS, etc. according to the default PDCCH format. In other examples, the base station 105 may also configure the plurality of DCI fields 330 to indicate a transmit power control (TPC) command. In some examples, the DCI (bit) field in the plurality of DCI fields 330 corresponding to each UE 115 may be configured to indicate one or more of the configuration index, TPC indication, or both.

[0152] Additionally or alternatively, the base station 105 may configure and reserve code points within a DCI bit field in the plurality of DCI fields 330 to indicate resource allocation for an initial (or previous) transmission for improving power boost for in-phase and quadrature phase (IQ) log likelihood ratio (LLR) combining. For uplink transmission, in some examples, the base station 105 may identify the power margin before issuing a TPC command to perform appropriate LLR combining at the UE 115 (e.g., at the receiver). For downlink transmission, the amount of power boost may depend on one or more scheduling conditions of the base station 105 for retransmitted symbols and may be indicated to the UE 115. In some examples, the base station 105 may configure multiple bits for each DCI for each UE 115. For example, the base station 105 may configure four bits for each DCI for each UE 115, wherein two of the four bits (e.g., 00xx) may be reserved to indicate the same grant configuration as the initial (or previous) transmission. The remaining two bits may be used to indicate additional information, such as the amount of power boost. By using two of the four bits for power indication, the base station 105 can use the remaining two bits to indicate different possible combinations of grant configurations (e.g., twelve different combinations). That is, the base station 105 can have the ability to use the remaining two bits to indicate twelve different grant configurations. In this way, the base station 105 and the plurality of UEs 115 can support twelve uplink configured grant configurations.

[0153] Certain aspects of GC-DCI 300 may be implemented to achieve one or more of the following potential advantages. GC-DCI 300 used by base station 105 and UE 115 may provide benefits and enhancements to the operation of UE 115. For example, operations performed by base station 105 and UE 115 may provide improvements to group scheduling applications. In some examples, base station 105 and UE 115 may support signaling including a configuration indication regarding a configured grant configuration to be used by UE 115, the configured grant configuration being used to support improvements to power consumption, spectral efficiency, higher data rates, and in some examples, may facilitate increased efficiency for high reliability and low latency operations, among other benefits.

[0154] References in this article Figure 4 and Figure 6 An exemplary group scheduling timeline is described in further detail.

[0155] Figure 4 4 shows an example of a group scheduling timeline 400 supporting group scheduling applications according to aspects of the present disclosure. The group scheduling timeline 400 may involve a base station 105 and a plurality of UEs 115, which may be reference Figure 1 and Figure 2In some examples, the group scheduling timeline 400 can implement aspects of the wireless communication systems 100 and 200, as described with reference to Figure 1 and Figure 2 For example, the group scheduling timeline 400 can be based on the configuration of the base station 105 or the plurality of UEs 115 and implemented by the plurality of UEs 115 to reduce power consumption, improve reliability, and can facilitate low latency of URLLC communication or IoT communication, among other benefits.

[0156] The operations of the group scheduling timeline 400 may occur in a different order than the example order shown, or the operations performed by the base station 105 and the plurality of UEs 115 may occur in a different order or at different times. Some operations may also be omitted from the group scheduling timeline 400, and other operations may be added to the group scheduling timeline 400. The group scheduling timeline 400 may include loops 405 and 410. In some examples, loops 405 and 410 may be continuous or discontinuous in the time domain. For example, loops 405 and 410 may be continuous or discontinuous TTIs. In some examples, loops 405 and 410 may be continuous or discontinuous in a subframe or time slot. Each time slot may include multiple symbol periods. Therefore, loops 405 and 410 may be continuous or discontinuous in multiple symbol periods. The group scheduling timeline 400 may illustrate an example process between group scheduling and multiple configured grants. More specifically, group scheduling timeline 400 may illustrate an example of group scheduling using multiple configured grants for downlink transmissions.

[0157] At 415, reference Figure 1 and 2 , multiple UEs 115 (e.g., UE 1, 2, ....., N, where N is a positive value) can receive a transport block according to a semi-persistent scheduling grant that is configured for initial transmission and activated individually or by GC-DCI. That is, in some examples, the base station 105 can individually or jointly enable each UE 115 of the multiple UEs 115 to activate a configured grant from multiple configured grants. For example, the base station 105 can individually enable each UE 115 of the multiple UEs 115 to activate a configured grant via separate dynamic signaling for each UE 115 (e.g., each DCI of each UE). Alternatively, the base station 105 can jointly enable multiple UEs 115 to activate a configured grant via GC-DCI.

[0158] Base station 105 may also provide an indication of whether the activated configured grant corresponds to an initial transmission or a retransmission. In some examples, the indication may be explicit for each UE 115 (e.g., via a bit in the DCI for each UE 115 within the GC-DCI), or for each group of UEs 115 (e.g., via a single bit in the GC-DCI). Alternatively, the indication may be implicitly signaled by base station 105, such as via RRC configuration, similarly for each UE 115 or each group of UEs 115.

[0159] At 420, the base station 105 may be one or more UEs 115 (e.g., UE k ,UE m ) determines the retransmission. At 425, the base station 105 may send a GC-PDCCH that schedules the retransmission on a downlink grant configured for the retransmission. At 430, the base station 105 may perform the retransmission for one or more UEs 115. At 435, during loop 410, one or more operations may be repeated. For example, multiple UEs 115 may receive a transport block according to a semi-persistent scheduling grant that is configured for initial transmission and activated individually or by GC-DCI.

[0160] Figure 5 An example of a group scheduling timeline 500 supporting group scheduling applications according to aspects of the present disclosure is shown. The group scheduling timeline 500 may involve a base station 105 and a plurality of UEs 115, which may be reference Figure 1 and Figure 2 In some examples, the group scheduling timeline 500 can implement aspects of the wireless communication systems 100 and 200, as described with reference to Figure 1 and Figure 2 For example, the group scheduling timeline 500 can be based on the configuration of the base station 105 or the plurality of UEs 115 and implemented by the plurality of UEs 115 to reduce power consumption, improve reliability, and other benefits.

[0161] The operations of the group scheduling timeline 500 may occur in a different order than the example order shown, or the operations performed by the base station 105 and the plurality of UEs 115 may occur in a different order or at different times. Some operations may also be omitted from the group scheduling timeline 500, and other operations may be added to the group scheduling timeline 500. The group scheduling timeline 500 may include loops 505 and 510. In some examples, loops 505 and 510 may be continuous or discontinuous in the time domain. For example, loops 505 and 510 may be continuous or discontinuous TTIs. In some examples, loops 505 and 510 may be continuous or discontinuous in a subframe or time slot. Each time slot may include multiple symbol periods. Therefore, loops 505 and 510 may be continuous or discontinuous in multiple symbol periods. The group scheduling timeline 500 may illustrate an example process between group scheduling and multiple configured grants. More specifically, group scheduling timeline 500 may illustrate an example of group scheduling using multiple configured grants for uplink transmissions.

[0162] At 515, reference Figure 1 and 2 , multiple UEs 115 (e.g., UE 1, 2, ....., N, where N is a positive value) can send a transport block according to an uplink configured grant that is configured for initial transmission and activated individually or by GC-DCI. That is, in some examples, the base station 105 can enable one or more UEs 115 in the multiple UEs 115 to activate a configured grant from multiple configured grants individually or jointly. For example, the base station 105 can individually enable each UE 115 in the multiple UEs 115 to activate a configured grant via separate dynamic signaling for each UE 115 (e.g., each DCI of each UE). Alternatively, the base station 105 can jointly enable multiple UEs 115 to activate a configured grant via GC-DCI. The base station 105 can also provide an indication of whether the activated configured grant corresponds to an initial transmission.

[0163] In some examples, the indication may be explicit for each UE 115 (e.g., via a bit in the DCI for each UE 115 within the GC-DCI), or for each group of UEs 115 (e.g., via a single bit in the GC-DCI). Alternatively, the indication may be implicitly signaled by the base station 105, such as via an RRC configuration, similarly per UE 115 or per group of UEs 115. At 520, the base station 105 may provide one or more UEs 115 (e.g., UE k ,UE m) determines the retransmission. At 525, the base station 105 may send a GC-PDCCH that schedules the retransmission on an uplink grant configured for retransmission. At 530, the base station 105 may perform the retransmission for one or more UEs 115. At 535, during loop 510, one or more operations may be repeated, for example, one or more UEs 115 of the plurality of UEs 115 may send a transport block on an uplink configured grant configured for initial transmission, activation alone, or activation by GC-DCI.

[0164] return Figure 2 In some examples, if base station 105 activates a semi-persistent scheduling grant (or an uplink configured grant) for retransmission via GC-DCI 205 (e.g., GC-DCI), the configured grant may be valid for a single retransmission and may be automatically released thereafter (e.g., without a deactivation command or a release command). For example, one or more UEs 115 in group 215 may release a configured grant corresponding to a configured grant configuration without a deactivation command or a release command.

[0165] In some examples, if the base station 105 activates a semi-persistent scheduling grant (or an uplink configured grant) for retransmission via GC-DCI 205, a feedback identifier (e.g., a HARQ identifier) ​​may be obtained. For example, one or more UEs 115 in group 215 may determine a feedback identifier corresponding to a data transmission, which may be a retransmission. In some examples, one or more UEs 115 in group 215 may determine the feedback identifier implicitly. For example, the feedback identifier may be related to a previous feedback identifier (e.g., the last received or transmitted HARQ identifier). This may be applicable to IoT communications, where the initial transmission may be based on a semi-persistently scheduled grant (or an uplink configured grant). If the initial transmission is based on a dynamic grant, missing the grant may have an adverse effect on the base station 105 and multiple UEs 115 (e.g., the feedback identifier cannot be implicitly determined). Alternatively, one or more UEs 115 in group 215 may determine the feedback identifier based on explicit signaling from the base station 105. For example, the base station 105 may include a feedback identifier field (eg, a HARQ identifier field) in the GC-DCI 205 for the DCI for each UE 115 .

[0166] In some examples, if the base station 105 activates the uplink configured grant for retransmission via GC-DCI 205, a timer associated with the feedback identifier corresponding to the retransmission may be started or restarted. For example, one or more UEs 115 in group 215 may start a timer for a feedback identifier corresponding to a data transmission, which may be a retransmission. In some examples, if the base station 105 activates a semi-persistent scheduling grant (or an uplink configured grant) for the transmission of a new transport block via GC-DCI 205, the configured grant may be valid before a deactivation command or a release command is decoded by one or more UEs 115 in group 215. That is, the activated configured grant may be considered to be activated or reactivated by a unicast DCI. In this case, one or more UEs 115 in group 215 may determine the feedback identifier from one or more transmit or receive opportunities (i.e., there is no explicit field for feedback).

[0167] Alternatively, in some examples, the base station 105 may activate a semi-persistent scheduling grant (or an uplink configured grant) via the GC-DCI 205 for an initial transmission, where the grant is not repeated (i.e., the configured grant is automatically released). In this case, the feedback identifier field of each UE 115 may indicate which feedback process (e.g., HARQ process) is scheduled by the GC-DCI 205. In some examples, whether a feedback identifier is included (e.g., a HARQ identifier bit field in the GC-DCI) may allow the UE 115 to implicitly distinguish whether the grant for a new transport block is a repeated grant (e.g., the GC-DCI does not include a HARQ identifier bit field) or a single grant (e.g., the GC-DCI includes a HARQ identifier bit field). In some examples, the GC-DCI 205 may be used for a single transmission. In this case, the grant carried in the GC-DCI 205 may not be repeated.

[0168] In some examples, the control signaling may include a HARQ field, and the UEs 115 of the group 215 may determine that the GC-DCI 205 activates semi-persistent resources or uplink configured grant resources for a single initial transmission, wherein the corresponding grant is not repeated (e.g., the configured grant is automatically released) based on the control signaling indicating that the GC-DCI 205 includes the HARQ field. Alternatively, in some examples, the control signaling may indicate that the GC-DCI 205 does not include the HARQ field. In this way, the UEs 115 in the group 215 may determine that the GC-DCI 205 activates semi-persistent resources or uplink configured grant resources for the initial transmission, wherein the grant is repeated (e.g., valid until the deactivation / release is decoded) based on the control signaling indicating that the HARQ field is not present in the GC-DCI 205.

[0169] In some examples, the base station 105 and the UE 115 may benefit from using the HARQ process number (HPN) field in the DCI to indicate which HARQ identifier is being sent. In some examples, if the DCI is configured to include the HPN field, it will indicate to the UE 115 that the grant for the initial transmission is valid for a single transmission or reception. Alternatively, if the HPN is not configured, the HPN will indicate that the grant is a duplicate (i.e., it is a downlink semi-persistently scheduled resource or an uplink configured resource) because the HARQ identifier in the semi-persistently scheduled or uplink configured grant is obtained from the reception or transmission opportunity (e.g., it may not be necessary to include the HPN bit field).

[0170] In some examples, the base station 105 may activate or respond to a semi-persistent scheduling grant or a type two uplink configured grant for an initial transport block transmission via GC-DCI 205, while a reactivation or deactivation may be sent via unicast DCI. Alternatively, the base station 105 may activate or respond to a semi-persistent scheduling grant or a type two uplink configured grant via unicast DCI, while it may be reactivated or released by GC-DCI 205. For a semi-persistent scheduling grant released by GC-DCI 205, the UE 115 may send an acknowledgment in a PUCCH resource (which may be RRC configured per UE 115), or indicated by a DCI in the GC-DCI 205 for each UE 115.

[0171] In some examples of group scheduling with a single DCI, the base station 105 may use one or more techniques to indicate the DCI bit field (e.g., DCI bit K) to different UEs 115 in the group 215. 0 and DCI bit K 1 In one example, the base station 105 may provide a DCI bit K associated with the TDRA. 0 and DCI bit K 2 One or more RRC configurations (e.g., RRC configuration values) in 0 Alternatively, in some examples, base station 105 may configure DCI bit K via dynamic indication (eg, via DCI signaling). 1 In some examples, DCI bit K 0 The DCI bit K may correspond to a delay between a downlink grant and corresponding downlink data reception (eg, via PDSCH). 1 The DCI bit K may correspond to a delay between downlink data reception (eg, via PDSCH) and corresponding acknowledgment transmission on the uplink. 2The K may correspond to the delay between uplink grant reception and uplink data transmission (eg, via PUSCH) in the downlink. The base station 105 may also explicitly indicate K in the DCI bit field indication for each UE. 0 , K 1 and K 2 Any or all of the above, base station 105 and UE 115 may benefit from having greater flexibility at the expense of a larger total DCI size. In some examples, base station 105 may support K in the DCI for UEs 115 (e.g., all UEs) in group 215 within GC-DCI 205. 0 , K 1 and K 2 An indication of any or all of the .

[0172] In some examples, in a downlink with group scheduling, the base station 105 may support various techniques for providing an indication of one or more PUCCH resources for HARQ-ACK for each UE 115. In one example, the base station 105 may configure one or more PUCCH resources for HARQ-ACK via RRC configuration. For multiple UEs 115 scheduled by GC-DCI, PUCCH resource management may become a problem by simply using RRC configuration. In this way, the base station 105 may alternatively introduce a PUCCH resource indication (PRI) in the DCI bitmap. This may be accompanied by some higher layer signaling (e.g., MAC-CE signaling, RRC signaling) to further reduce the PUCCH resource indication of the DCI. For example, for the first PUCCH resource set, where the set size can reach 32 PUCCH resources, MAC-CE selects 8 (or 4) resources downward; then 3 (or 2) bits in the DCI can indicate which PUCCH resource each UE 115 is to use.

[0173] Figure 6 1 shows an example of a group scheduling timeline 600 supporting group scheduling applications according to aspects of the present disclosure. The group scheduling timeline 600 may involve a base station 105 and a plurality of UEs 115, which may be reference Figure 1 and Figure 2 In some examples, the group scheduling timeline 600 can implement aspects of the wireless communication systems 100 and 200, as described with reference to Figure 1 and Figure 2 For example, the group scheduling timeline 600 can be based on the configuration of the base station 105 or multiple UEs 115, and implemented by multiple 115 to reduce power consumption, improve reliability, and it can promote low latency of URLLC communication or IoT communication, as well as other benefits.

[0174] refer to Figure 1 and Figure 2 , group scheduling timeline 600 can illustrate the behavior of UE 115 when a grant from GC-DCI overlaps with unicast DCI. In some examples, if one or more UEs 115 receive a grant from GC-DCI and unicast DCI that overlap in the time domain (e.g., for a given HARQ identifier), then one or more UEs 115 can follow the UE-specific grant. In some examples, if the number of symbols N X 620 (e.g., the number of symbols between the last symbol of the PDCCH carrying the DCI 605 for the UE-specific grant and the first symbol of the overlapping grant (e.g., associated with PDSCH 610 and PDSCH 615)) is greater than N+X, where X can be 0 or 1, etc., then one or more UEs 115 can follow the UE-specific grant. In some examples, for downlink transmissions, N=N1 (4.5 OFDM symbols OS for 30kHz subcarrier spacing). In some examples, for uplink transmissions, N=N2 (5.5 OS for 30kHz subcarrier spacing). In other examples, if the GC-PDCCH ends after the UE-specific PDCCH, then one or more UEs 115 can follow the UE-specific grant. In some examples, one or more UEs 115 can avoid receiving overlapping grants from GC-DCI and unicast DCI that do not meet the above criteria. In some examples, one or more UEs 115 can identify an error based on the number of symbols N between the last symbol of a control channel (e.g., PDCCH) transmitting the unicast DCI and the first symbol indicated in the grant or the second grant. X 620 The threshold is not met, or the last symbol of the group control channel transmitting the GC-DCI does not end after the last symbol of the second control channel transmitting the unicast DCI, or both.

The process flow 700 may include the base station 105 and a UE 115 in a group of UEs 115, and the UE 115 may be a reference Figure 1 and Figure 2In the following description of process flow 700, operations between base station 105 and UE 115 may be sent in a different order than the example order shown, or operations performed by base station 105 and UE 115 may be performed in a different order or at a different time. Some operations of process flow 700 may also be omitted, and other operations may be added to process flow 700.

In some examples, receiving the control signaling may include UE 115 receiving control signaling indicating a group identifier assigned to a plurality of UEs 115. The group DCI may be received based on the group identifier. In some examples, receiving the control signaling may include UE 115 receiving control signaling indicating a payload size of the group DCI. UE 115 may receive the group DCI based on the payload size. In some other examples, receiving the control signaling may include UE 115 receiving control signaling indicating a serving cell identifier. At 725, UE 115 may transmit a data transmission to base station 105 based on the configuration indication in the group DCI indicating the configured granted configuration, e.g., according to a configured granted configuration in the set of configured granted configurations.

[0177] In some examples, UE 115 may transmit a data transmission to base station 105, for example, on a carrier corresponding to a serving cell identifier. In some examples, receiving control signaling may include UE 115 receiving control signaling indicating a starting position indicator. A configuration indication may be identified for UE 115 within a group DCI based on the starting position indicator. UE 115 may decode the group DCI corresponding to the starting position indicator to obtain at least one parameter. Data transmission may be sent based on the at least one parameter. In other examples, UE 115 may receive control signaling indicating a send power control command, and the data transmission may be sent by UE 115 based on the send power control command. UE 115 may alternatively receive control signaling indicating a send power control command, and the configuration indication may include an index corresponding to a configured permitted configuration for data transmission.
