Hybrid Scheduling Technology

Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a hybrid scheduling configuration that includes a dynamic scheduling indication, a pre-configuration including initial scheduling parameters, and a set of pre-configured timings for communicating data with a base station. The UE may monitor the dynamic scheduling indication based on the initial scheduling parameters and the set of pre-configured timings. For example, the UE may monitor the dynamic scheduling indication during a periodic timing, monitor the dynamic scheduling indication using different periodicities, or monitor based on a time interval (e.g., a time slot) during which both the pre-configured timing and the dynamic scheduling indication occur. In any case, the UE may communicate with the base station after receiving the dynamic scheduling indication, where data may be sent to or received from the base station according to the hybrid scheduling configuration.

[0002] This patent application claims priority to U.S. Patent Application No. 17 / 124,189, entitled "HYBRID SCHEDULING TECHNIQUES," filed on Dec. 16, 2020, by Xu et al., and U.S. Provisional Patent Application No. 62 / 950,092, entitled "HYBRID SCHEDULING TECHNIQUES," filed on Dec. 18, 2019, by Xu et al., each of which is assigned to the assignee of the present application. Background of the disclosure

[0003] The following generally relates to wireless communications and, more specifically, to hybrid scheduling techniques.

[0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi-access systems include fourth-generation (4G) systems such as Long-Term Evolution (LTE) systems, LTE-Advanced (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 Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multi-access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices, which may otherwise be referred to as user equipment (UE).

[0005] A base station may send scheduling information that may, for example, indicate downlink resource allocation, uplink transmission authorization, or both. However, in some cases, frequently sent scheduling information may create unnecessary overhead in the system. On the other hand, techniques using non-dynamic scheduling may not provide sufficient flexibility to adjust scheduling parameters or adapt to different types of traffic in the system. Summary of the disclosure

[0006] The described techniques relate to improved methods, systems, devices, and apparatuses that support hybrid scheduling techniques. Generally, the described techniques provide a hybrid scheduling configuration. The hybrid scheduling configuration can include both preconfigured scheduling opportunities (e.g., during which data can be scheduled and communicated) and dynamic scheduling information that can indicate the scheduling opportunities during which data can be communicated. As such, one or more user equipment (UEs) can be configured with preconfigured information that can indicate a set of scheduling opportunities and scheduling parameters, such as resource allocation information, decoding scheme information, feedback timing, and so on. In some cases, the dynamic scheduling information can indicate additional or alternative scheduling information that modifies or replaces some of the initial, preconfigured scheduling parameters. The dynamic scheduling information can be compact (e.g., providing a prudent amount of information), support efficient decoding, and in some examples can include UE-specific information for multiple UEs. In some cases, the dynamic scheduling information can reduce the decoding complexity and power consumption at the UE, thereby improving UE power efficiency. The dynamic scheduling information can additionally or alternatively improve scheduling flexibility.

For example, a base station may determine that data is available for transmission to or from a user equipment (UE), and the base station may send a scheduling indication (e.g., a physical downlink control channel (PDCCH) with a dynamic grant for the scheduled data) each time the data is to be communicated. However, such dynamic scheduling may create overhead in the system, especially when a large number of UEs are receiving small amounts of data frequently. Thus, techniques that can reduce the signaling of scheduling information (such as semi-persistent scheduling (SPS)) may enable the configuration of periodic resources for data transmission that can be activated and deactivated for a UE.

[0088] In some cases, SPS may reduce the scheduling information processing performed at the UE, where the UE may start decoding data (e.g., on a physical downlink shared channel (PDSCH)) based on a configured grant. However, in such cases, the UE may sometimes process or attempt to process data that does not exist or is not available to the UE based on the configured grant. For example, when the data for a UE is sparse and / or aperiodic, the UE may attempt to decode an empty grant (e.g., where no PDSCH is available) based on the SPS configuration, which may unnecessarily increase the power usage of the UE. In some examples, decoding the PDSCH may be more resource intensive than decoding the PDCCH (e.g., three times more resource intensive). SPS parameters may also limit scheduling flexibility. For example, SPS parameters may only be preconfigured or changed per activation instance, and these parameters may not be adjustable dynamically.

[0089] According to aspects described herein, hybrid scheduling can be used to combine both preconfigured scheduling opportunities and dynamic scheduling indications. For example, the hybrid scheduling techniques described can include both preconfigured scheduling opportunities (e.g., periodic opportunities in which data can be communicated, which can be based on SPS or configured grant configuration) and dynamic scheduling information (e.g., downlink control information (DCI), compact DCI, etc.). The preconfigured scheduling information can provide initial scheduling parameters, which include the pattern of scheduling opportunities for one or more UEs (e.g., slot periodicity, offset). The preconfigured scheduling opportunity can be based on SPS, and in some cases, the preconfigured opportunity can be at a loose periodicity (e.g., every 5 milliseconds (ms)). The preconfigured information can provide the pattern of monitoring slots (e.g., slot periodicity, offset). The dynamic scheduling information can be group common (e.g., used by each UE in a particular group of one or more UEs) and include UE-specific information for one or more UEs. In some cases, the dynamic scheduling information can include a subset of the scheduling parameters that are dynamically dispatched for one or more scheduled UEs (e.g., time domain resource allocation (TDRA), modulation and coding scheme (MCS), hybrid automatic repeat request (HARQ) feedback timing). The dynamic scheduling information can indicate whether an operation (e.g., decoding the PDSCH) should be performed by the UE and can additionally or alternatively provide certain parameters that facilitate the scheduling of data (e.g., PDSCH) adjustments.

[0090] Hybrid scheduling can provide one or more advantages within a system, including reducing system overhead, minimizing unnecessary decoding at the receiving device, and providing scheduling flexibility. As an example, the preconfigured scheduling information can indicate multiple opportunities in which data can be scheduled, and the dynamic scheduling information (e.g., dynamic PDCCH) can be monitored by the UE during each opportunity, which may be less complex and power intensive than decoding (or attempting to decode) the PDSCH at periodic intervals. As such, the dynamic scheduling information can reduce unnecessary decoding by indicating whether the UE should decode one or more data transmissions (e.g., PDSCH), while also allowing for periodic transmissions with reduced signaling overhead (e.g., compared to separate dynamic scheduling). The dynamic scheduling information can provide scheduling flexibility by supporting the transmission of scheduling adjustments, which can be based on changes in traffic or other factors. As such, hybrid scheduling can provide an improved tradeoff between dynamic scheduling overhead (e.g., transmission scheduling message capacity, UE power consumption) and scheduling flexibility.

[0091] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects are subsequently described with respect to scheduling configurations and control information that enable hybrid scheduling schemes. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flowcharts associated with hybrid scheduling techniques.

[0092] Figure 1 The figure illustrates an example of a wireless communication system 100 that supports hybrid scheduling techniques in accordance with aspects of the present disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In certain examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In certain examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low latency communication, communication with low-cost and low-complexity devices, or any combination thereof.

[0093] 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 having 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, and the UEs 115 and the base stations 105 may establish one or more communication links 125 over the coverage area 110. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support signal communication in accordance with one or more radio access technologies.

[0094] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both at different times. The UEs 115 may be devices of different forms or having different capabilities. Certain example UEs 115 are shown in Figure 1 as. As Figure 1 shown, the UEs 115 described herein may be capable of communicating with various types of devices (such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment)).

[0095] The base stations 105 may communicate with the core network 130 or with each other, or both. 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 base stations 105) or indirectly (e.g., via the core network 130) (or both) via backhaul links 120 (e.g., via X2, Xn, or other interfaces). In certain examples, the backhaul links 120 may be or include one or more wireless links.

[0096] 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 transceiver station, radio base station, access point, radio transceiver, Node B, eNodeB (eNB), next-generation Node B, or Gigabit-NodeB (any of which may be referred to as a gNB), home Node B, home eNodeB, or other suitable terms.

[0097] The UE 115 may include or may be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, station, terminal, or client, etc. The UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, the UE 115 may include or may be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine type communication (MTC) device, etc., which may be implemented in various articles, such as appliances, vehicles, meters, etc.

[0098] As Figure 1 shown, the UE 115 described herein may be capable of communicating with various types of devices, such as other UE 115s that may sometimes act as relays, and base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc.

[0099] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 over one or more carriers. The term "carrier" may refer to a collection 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 (e.g., a bandwidth part (BWP)) of a radio frequency spectrum band that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating the operation of the carrier, user data, or other signaling. The wireless communication system 100 may support communicating with the UE 115 using carrier aggregation or multi-carrier operation. According to a 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 frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0100] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunication system terrestrial radioaccess (E-UTRA) absolute RF channel number (EARFCN)), and may be positioned according to a channel raster to be discovered by UE 115. A carrier may operate in an independent mode, where initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-independent mode, where a different carrier (e.g., a carrier of the same or different radio access technology) is used to anchor the connection.

[0101] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from UE 115 to the base station 105, or a downlink transmission from the base station 105 to UE 115. A carrier may carry downlink or uplink communication (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0102] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier frequency bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier frequency bandwidth may be one of a plurality of determined bandwidths for 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., the base station 105 or UE 115 or both) may have a hardware configuration that supports communication through a specific carrier frequency bandwidth, or may be configured to support communication through one of a set of carrier frequency bandwidths. In some examples, the wireless communication system 100 may include a base station 105 and / or UE 115 that supports simultaneous communication via carriers associated with multiple carrier frequency 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 frequency bandwidth.

[0103] The signal waveform transmitted via a carrier can be composed of multiple sub-carriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system adopting MCM techniques, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a sub-carrier, where the symbol period and the sub-carrier spacing are negatively correlated. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the decoding rate of the modulation scheme, or both). Therefore, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate for UE 115 can be. Wireless communication resources can 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 can further improve the data rate or data integrity for communication with UE 115.

[0104] One or more parameter sets for a carrier can be supported, where the parameter set can include sub-carrier spacing (Δf) and cyclic prefix. A carrier can be divided into one or more BWPs with the same or different parameter sets. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and the communication for UE 115 can be restricted to one or more active BWPs.

[0105] The time interval for the base station 105 or UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can refer to, for example, T s = 1 / (Δf max ·N f ) seconds of sampling period, where Δf max can represent the maximum supported sub-carrier spacing, and N f can represent the maximum supported discrete Fourier transform (DFT) size. The time interval of communication resources can be organized according to radio frames, and each radio frame has a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a system frame number (SFN) (e.g., in the range from 0 to 1023).

[0106] Each frame may include a plurality of consecutively numbered sub - frames or time slots, and each sub - frame or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into sub - frames, and each sub - frame 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 sub - carrier spacing. Each time slot may include a plurality of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini - time slots each containing one or more symbols. Except for the cyclic prefix, each symbol period may contain one or more (e.g., N f ) sampling periods. The duration of a symbol period may depend on the sub - carrier spacing or the operating frequency band.

[0107] A sub - frame, time slot, mini - time 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 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 a burst of shortened TTIs (sTTIs)).

[0108] Physical channels may be multiplexed on a carrier according to various techniques. For example, time - division multiplexing (TDM) techniques, frequency - division multiplexing (FDM) techniques, or one or more of hybrid TDM - FDM techniques may be used to multiplex physical control channels and physical data channels on a downlink carrier. The control region of a physical control channel (e.g., a control resource set (CORESET)) may be defined by a number of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search a control region for control information according to one or more sets of search spaces, and each set of search spaces may include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level of a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the encoded information of a control information format having a given payload size. The set of search spaces 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.

[0109] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity for communicating with the base station 105 (e.g., via a carrier), and may be associated with an identifier for distinguishing adjacent cells (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), etc.). In some examples, a cell may also refer to a geographic coverage area 110 or a portion (e.g., a sector) of the geographic coverage area 110 on which the logical communication entity operates. The scope of such cells may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area, depending on various factors such as the capabilities of the base station 105. For example, a cell may be or include a building, a subset of a building, or an external space between or overlapping with the geographic coverage area 110, and so on.

[0110] Macro cells typically cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access to UEs 115 having a service subscription with the network provider that supports the macro cell. Compared with macro cells, small cells may be associated with a base station 105 having a lower power, and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. A small cell may provide unrestricted access to UEs 115 having a service subscription with the network provider, or may provide limited access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). The base station 105 may support one or more cells and may also support communication using one or more component carriers on one or more cells.

[0111] 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)), which may provide access for different types of devices.

[0112] In some examples, the base station 105 may be movable and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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.

[0113] Wireless communication system 100 may support synchronous operation or asynchronous operation. For synchronous operation, base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, base stations 105 may have different frame timings, 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 operation or asynchronous operation.

[0114] Certain 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 technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application, which utilizes the information or presents the information to a human interacting with the application. Certain UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications of MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, health monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0115] Certain UEs 115 may be configured to operate in power-saving modes, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but does not support simultaneous transmission and reception). 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 participating in active communication, or operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, certain UEs 115 may be configured to operate using a narrowband protocol type associated with a defined portion or range within a carrier, within a guard band of the carrier, or outside the carrier (e.g., a set of subcarriers or resource blocks (RBs)).

[0116] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 may be designed to support ultra-reliability, low latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication and may 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 may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low latency, mission-critical, and ultra-reliable low latency may be used interchangeably herein.

[0117] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 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 geographical coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographical coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system where 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 participation of the base station 105.

[0118] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UEs 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. Vehicles may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as a roadside unit) or communicate with the network using vehicle-to-network (V2N) communication via one or more network nodes (e.g., the base station 105), or both.

[0119] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets or interconnects to an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for a UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered through the 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.

[0120] Some of the network devices (such as the base station 105) may include subcomponents, such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with a UE 115 through one or more other access network transmit entities 145, which may be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP). Each access network transmit 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 combined into a single network device (e.g., the base station 105).

[0121] The wireless communication system 100 may operate using one or more frequency bands in the range of, for example, 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or the decimeter band because the wavelength range is from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but these waves can penetrate structures sufficiently to enable a macro cell to serve a UE 115 located indoors. Compared to transmissions at smaller frequencies and longer wavelengths using the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers).

[0122] The wireless communication system 100 may also operate in the super high frequency (SHF) region (also known as the centimeter band) using a frequency band from 3 GHz to 30 GHz or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be smaller and closer spaced than UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer from greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the specified use of frequency bands across these frequency regions may vary by country or regulatory body.

[0123] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ Licensed 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 the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in the unlicensed band may be based on a carrier aggregation configuration together with a component carrier operating in a licensed band (e.g., LAA). Among other examples, operation in the unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions.

[0124] The base station 105 or the UE 115 may be equipped with multiple antennas that may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the base station 105 or the UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operation, 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 with antenna ports arranged in multiple rows and columns, and the base station 105 may use this antenna array to support beamforming for communication 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, an antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0125] Base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques can be referred to as spatial multiplexing. For example, multiple signals can be transmitted by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.

[0126] Beamforming (which can 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., base station 105, UE 115) to shape or 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 communicated via the antenna elements of an antenna array such that certain signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. The adjustment of the signals communicated via the antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0127] Base station 105 or UE 115 can use beam scanning techniques as part of a beamforming operation. For example, base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to perform a beamforming operation to communicate directionally with UE 115. Certain signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) can be transmitted by base station 105 multiple times in different directions. For example, base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used to identify (e.g., by the transmitting device, such as base station 105, or the receiving device, such as UE 115) the beam direction for subsequent transmissions or receptions by base station 105.

[0128] Certain 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., the direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with transmission along a 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 that UE 115 receives with the highest signal quality or with other acceptable signal quality.

[0129] In some examples, multiple beam directions may be used to perform transmission by a device (e.g., base station 105 or UE 115), and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to the number of configured beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)), which may be precoded or non-precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., for transmitting data to a receiving device).

[0130] A receiving device (e.g., UE 115) may attempt multiple receive configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, the receiving device may attempt multiple receive directions by: receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as “listening” according to different receive configurations or receive directions. In some examples, the receiving device may use a single receive configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receive configuration may be aligned with 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 other acceptable signal quality based on listening according to multiple beam directions).

[0131] The wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, 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 for communication over logical channels. The Medium Access Control (MAC) layer may perform priority handling and multiplexing from logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer may provide support for the establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or the core network 130 for radio bearers of user plane data. At the physical layer, transport channels may be mapped to physical channels.

[0132] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid Automatic Repeat reQuest (HARQ) feedback is a technique for increasing the likelihood that data is correctly received over communication link 125. HARQ may include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), Forward Error Correction (FEC), and retransmission (e.g., Automatic Repeat reQuest (ARQ)). HARQ may improve the throughput of the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a particular slot for data received in previous symbols in that slot. In other cases, the device may provide HARQ feedback in a subsequent slot or according to some other time interval.

[0133] In some cases, wireless communication system 100 may use dynamic scheduling. For dynamic scheduling, when there is data available for one or more UEs 115, base station 105 may send Downlink Control Information (DCI) indicating scheduling information to one or more UEs 115 via the Physical Downlink Control Channel (PDCCH). Thus, the PDCCH carries scheduling information for the UE 115 to decode the scheduled data channel (e.g., Physical Downlink Shared Channel (PDSCH)). Additionally or alternatively, wireless communication system 100 may support Semi-Persistent Scheduling (SPS) for downlink transmissions. In such a case, the periodicity of data transmission may be indicated via Radio Resource Control (RRC) signaling. Further, a PDCCH scrambled by a specific Radio Network Temporary Identifier (RNTI) (e.g., Configured Scheduling - RNTI (CS - RNTI)) may be used to activate SPS. In some cases, the PDCCH for SPS may include information such as time - frequency resources and other parameters for receiving downlink transmissions. Once SPS is activated, data may be received at UE 115 during one or more occasions based on the scheduling information of the PDCCH that activated SPS. Further, when base station 105 determines to stop SPS data transmission (e.g., there may no longer be any data to send to UE 115), base station 105 may send a PDCCH to release the SPS (and the configured resources for downlink transmission).

[0134] In other cases, the wireless communication system 100 may also support configured grants for uplink communication. In such cases, uplink configured grant communication may be similar to SPS, but may be used for uplink communication. Here, multiple types of configured grant configurations may be used, which may be referred to as type 1 configured grant or type 2 configured grant (or other similar terms). For type 1 configured grant, scheduling information may be provided to the UE 115 via RRC configuration, which may include information such as periodicity, resources for data transmission, and activation indication. For type 2 configured grant, RRC may provide data transmission periodicity, and the PDCCH may provide other information for uplink transmission, including activation of data transmission according to the uplink configured grant (and / or release of the uplink configured grant).

[0135] The wireless communication system 100 may also support the use of hybrid scheduling techniques, which may provide enhancements to dynamic scheduling and SPS schemes. For example, the UE 115 may receive an indication of a hybrid scheduling configuration, which may include a set of using dynamic scheduling indication (e.g., dynamic PDCCH), pre-configured including initial scheduling parameters, and pre-configured timing for communicating data (e.g., with the base station 105). Based on the set of initial scheduling parameters and pre-configured timing, the UE 115 may monitor the dynamic scheduling indication sent by the base station 105 and may communicate with the base station 105 when the dynamic scheduling indication is received.

[0136] Figure 2 The figure illustrates an example of a wireless communication system 200 that supports hybrid scheduling techniques in accordance with aspects of the present disclosure. In certain examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 includes a base station 105-a, a geographic coverage area 110-a, and one or more UEs 115. In certain cases, the wireless communication system 200 may use hybrid scheduling techniques to enhance scheduling and communication flexibility within the system.

[0137] Base station 105-a can communicate with one or more UEs 115 (e.g., UEs 115-a, 115-b, and 115-c), which may be included in UE group 210. For example, base station 105-a may send hybrid scheduling configuration 205 to UE 115-a, UE 115-b, or UE 115-c. Hybrid scheduling configuration 205 may include preconfigured scheduling information 215 and dynamic scheduling indication 220 (e.g., PDCCH including DCI). In some cases, hybrid scheduling configuration 205 may be signaled to UE 115 via RRC signaling. Preconfigured scheduling information 215 may include configuration information (e.g., initial scheduling parameters, etc.) and may further indicate a set of preconfigured timing (e.g., slot periodicity, offset, etc.) and / or activation information (e.g., activated PDCCH information). In some cases, the configuration information may indicate the allocated resources for one or more UEs 115 (e.g., of UE group 210). Dynamic scheduling indication 220 may be sent by base station 105-a based on the allocated resources indicated in the configuration information.

[0138] Dynamic scheduling indication 220 may include information associated with one or more UEs 115 of UE group 210 (e.g., group common, UE specific information). For example, dynamic scheduling indication 220 may include one or more data fields corresponding to UE 115-a, one or more data fields corresponding to UE 115-b, and so on. In some cases, dynamic scheduling indication 220 may be group common and may indicate to one or more UEs 115 whether the UEs 115 may decode downlink data transmissions (e.g., PDSCH) during a set of preconfigured timing according to hybrid scheduling configuration 205. In some examples, dynamic scheduling information 220 may be sent to UE group 210 and may implicitly or explicitly indicate that UEs 115-b and 115-c may avoid decoding downlink data transmissions and UE 115-a should decode downlink data transmissions. Dynamic scheduling indication 220 may be compact (e.g., including a smaller payload, including a fallback DCI format, or a DCI that is relatively less complex compared to other DCI formats) and / or multicast, thereby improving system efficiency. For example, dynamic scheduling indication 220 may exclude certain scheduling parameters and support efficient decoding. Thus, dynamic scheduling indication 220 may support efficient spectrum usage because dynamic scheduling indication 220 may include scheduling information for multiple UEs 115 of UE group 210. Dynamic scheduling indication 220 may additionally or alternatively improve UE power consumption by indicating to UE 115 whether downlink data transmissions should be decoded. For example, dynamic scheduling indication 220 may reduce or eliminate unnecessary UE operations (e.g., decoding) associated with downlink data transmissions that would otherwise be performed by one or more UEs 115.

[0139] Communication between base station 105a and one or more UEs 115 may be based on a hybrid scheduling configuration 205, including using initial scheduling parameters, a set of preconfigured timing, and dynamic scheduling indication 220. The preconfigured and initial scheduling parameters included in the preconfigured scheduling information 215 may be based on SPS or configured grant. For example, if the data transmission associated with the preconfiguration is a downlink transmission, the preconfiguration may be based on SPS, and if the data transmission associated with the preconfiguration is an uplink transmission, the preconfiguration may be based on configured grant.

[0140] In some cases, the dynamic scheduling indication 220 (e.g., PDCCH) may be based on a PDCCH configured by a control resource set (CORESET) and a search space set. In some examples, the CORESET and the search space set may be dedicated to the dynamic scheduling indication. The CORESET may provide information about the frequency domain resources for the PDCCH and / or the number of consecutive OFDM symbols for the monitoring occasion. The search space set may provide the periodicity and offset of the monitoring occasion, the starting symbol of the monitoring occasion in the time interval, or other information, such as one or more aggregation levels and / or the number of PDCCH candidates for the PDCCH. In some examples, the time interval may be a transmission time interval, a time slot, a sub-slot, a symbol, etc.

[0141] Figure 3 The figure illustrates an example of a scheduling configuration 300 that supports hybrid scheduling techniques according to aspects of the present disclosure. In some examples, the scheduling configuration 300 may implement aspects of wireless communication systems 100 and 200. For example, the scheduling configuration may be used by UE 115 and base station 105, where UE 115 may monitor a set of preconfigured timing for the dynamic scheduling indication.

[0142] As an illustrative example, base station 105 may send a hybrid scheduling configuration that includes an indication of preconfigured timing for data transmission. The hybrid scheduling configuration may include an indication of the preconfigured timing periodicity 310 and / or the preconfigured timing for one or more UEs 115. For example, as described with reference to Figure 2 The preconfigured timing periodicity 310 may be indicated in the preconfigured scheduling information 215-a.

[0143] According to the scheduling configuration 300, UE 115 may monitor multiple preconfigured timing 305, where the preconfigured information indicated to UE 115 may provide a pattern of scheduling timing (e.g., time slot periodicity and offset). Thus, UE 115 may monitor the signaling based on the preconfigured timing periodicity 310, where UE 115 may attempt to decode the downlink control information during each preconfigured timing 305.

[0144] In some cases, and as described herein, the dynamic scheduling indication may have different periodicities (e.g., based on the configuration of the set of search spaces), which may define a pattern different from the pattern of the scheduling occasion. As such, there may be one or more preconfigured occasions 305-a where the dynamic scheduling indication is not detected, while there may also be one or more preconfigured occasions 305-b where the dynamic indication is detected. Accordingly, the UE 115 may use various techniques to determine the monitoring occasion to monitor the dynamic scheduling indication and data transmission.

[0145] Figure 4A and 4B The figures illustrate examples of scheduling configurations 400 and 401 that support hybrid scheduling techniques in accordance with aspects of the present disclosure. In some examples, the scheduling configurations 400 and 401 may implement aspects of the wireless communication systems 100 and 200. The scheduling configurations 400 and 401 may illustrate various configurations for both the preconfigured occasion and the dynamic scheduling indication that are part of a hybrid scheduling scheme. The preconfigured occasion and the dynamic scheduling indication may have the same or different periodicities, and the UE 115 may determine whether to perform monitoring (e.g., monitor downlink signaling, including data and / or dynamic signaling indication) based on the respective configurations.

[0146] As Figure 4A shown, the pattern of the preconfigured occasion 405 may be consistent with (e.g., the same as) the pattern of the dynamic indication monitoring occasion 410, and in some cases, the base station 105 or the network entity may ensure that the pattern of the preconfigured occasion 405 corresponds to the pattern of the dynamic indication monitoring occasion 410 (e.g., through the configuration of the hybrid scheduling scheme). For example, the time interval 425 (e.g., time slot) in which the dynamic indication (e.g., PDCCH) is configured to be monitored may also be the preconfigured occasion 405. For example, the time intervals 425 may each correspond to both the preconfigured occasion 405 and the dynamic indication monitoring occasion 410. In some cases, the preconfigured occasion periodicity 415-a may be the same length as the dynamic indication periodicity 420-a (e.g., the same duration, the same number of time slots, the same number of symbol periods).

[0147] As Figure 4B shown, the preconfigured occasion 405 may be a subset of the time interval (e.g., time slot) of the dynamic indication monitoring occasion 410. In some cases, the time interval of the dynamic indication monitoring occasion 410 may be monitored by the UE 115 according to the associated set of search space configurations. For example, according to the set of search space configurations, the UE 115 may monitor the time interval 430 for downlink transmission (e.g., PDCCH).

[0148] In some examples, the UE 115 may monitor dynamic scheduling information based on a preconfigured occasion 405. For example, the UE 115 may monitor dynamic indications (e.g., DCI, compact DCI, PDCCH, etc.) at those same time intervals based on the preconfigured occasion 405 at time interval 430. In some cases, if the time interval is not associated with both the preconfigured occasion 405 and the dynamic indication monitoring occasion time interval (e.g., the preconfigured occasion does not overlap with the dynamic indication monitoring time interval), the UE 115 may avoid monitoring that time interval for dynamic indications. For example, the UE 115 may avoid monitoring (e.g., ignoring) the time intervals 435 in the search space set configuration because those time slots may not include both the preconfigured occasion 405 and the monitoring occasion for dynamic indications.

[0149] In some cases, the UE 115 may monitor the dynamic indication monitoring occasion 410 based on the time interval being included in the preconfigured occasion 405 and the time interval being included in the dynamic indication monitoring occasion pattern based on the search space set configuration.

[0150] In other examples, the UE 115 may monitor the time interval 430 based on the dynamic indication monitoring occasion 410. For example, the UE 115 may monitor the time intervals 430 and 435 according to the search space set configuration associated with the dynamic indication monitoring occasion 410. In some examples, the preconfigured occasion 405 may be a subset of the dynamic indication monitoring occasion 410, and the UE 115 may monitor the time interval 430 based on the dynamic indication monitoring occasion 410. Monitoring the time interval 430 (e.g., time slot) based on the dynamic indication time interval may improve communication for receiving retransmissions of hybrid transmission scheduling.

[0151] Multiple patterns of the preconfigured occasion 405 may be associated with the UE 115. For example, a first pattern of the preconfigured occasion 405 for uplink communication and a second pattern of the preconfigured occasion 405 for downlink communication may be provided to the UE 115. In some additional or alternative examples, one or more patterns of the preconfigured occasion 405 for uplink communication and / or one or more patterns of the preconfigured occasion 405 for downlink communication may be provided to the UE 115.

[0152] In some cases, the UE 115 may be associated with multiple patterns of the preconfigured timing 405, and each of the multiple patterns of the preconfigured timing 405 may be associated with a pattern that dynamically indicates the monitoring timing 410. The pattern that dynamically indicates the monitoring timing 410 may indicate, for example, whether data is scheduled within an associated preconfigured timing (e.g., time interval). In some examples, the association between the pattern of the preconfigured timing 405 and the pattern that dynamically indicates the monitoring timing 410 may be specified by certain scheduling (e.g., RRC messaging). In some additional or alternative examples, the association between the pattern of the preconfigured timing 405 and the pattern that dynamically indicates the monitoring timing 410 may be specified by the content sent (e.g., PDCCH).

[0153] In some cases, the pattern that dynamically indicates the monitoring timing 410 may be associated with multiple patterns of the preconfigured timing 405. For example, the same set of bits in the dynamic indication (e.g., PDCCH) that dynamically indicates the monitoring timing 410 may be used to indicate whether any of the multiple patterns of the preconfigured timing 405 has data within a time interval (e.g., time slot). In additional or alternative examples, different sets of bits in the dynamic indication (e.g., PDCCH) received during one or more monitoring timings 410 may indicate whether the associated preconfiguration of the multiple patterns (e.g., preconfigured timing 405) has data for the UE 115.

[0154] Figure 5 The figure illustrates an example of a scheduling configuration 500 that supports hybrid scheduling techniques in accordance with aspects of the present disclosure. In some examples, the scheduling configuration 500 may implement aspects of the wireless communication systems 100 and 200. The scheduling configuration 500 may illustrate a retransmission schedule for hybrid scheduling in accordance with aspects of the present disclosure.

[0155] As described herein, using a hybrid scheduling configuration, the UE 115 may monitor a preconfigured timing for data and control information that dynamically signals the presence of the data during one or more preconfigured timings. However, in some cases, the UE 115 may not receive or decode an initial transmission of data received during the preconfigured timing. As such, the base station 105 may retransmit the data to the UE 115.

[0156] Thus, retransmissions associated with previous data transmissions during a preconfigured occasion can be dynamically scheduled in another occasion (e.g., time interval, time slot, etc.). For example, UE 115 can be associated with a pattern of preconfigured occasions for initial data transmission 505, and UE 115 can receive new transmission 510 based on the pattern of preconfigured occasions for new transmission 505. In some cases, a dynamic indication (e.g., via PDCCH) can indicate whether there is a new transmission based on preconfiguration and / or whether there is a retransmission of preconfigured data in a time interval (e.g., time slot). The indication of new transmission can take effect in the preconfigured occasion. In some cases, the indication of new transmission can only take effect in the preconfigured occasion (e.g., be ignored in non-preconfigured occasions). In some cases, if the dynamic indication (e.g., PDCCH) indicates that there is a retransmission in a time interval (e.g., time slot), UE 115 can further decode a unicast scheduling transmission for the retransmitted data (e.g., via PDCCH).

[0157] The dynamic scheduling indication can use the same indication for both new data and retransmissions of preconfigured data transmissions. For example, if the dynamic indication (e.g., PDCCH) indicates that data is scheduled, UE 115 can process both new data and retransmissions in the preconfigured occasion, and if UE 115 is configured to receive retransmissions in other time intervals, UE 115 can process retransmissions only in other time intervals (e.g., non-preconfigured time intervals). In some examples, retransmissions may not be allowed to be scheduled in the preconfigured occasion. For example, if the dynamic indication indicates that data is scheduled, UE 115 can process new data in the preconfigured occasion, and UE 115 can process retransmissions in other time intervals where the dynamic indication is monitored.

[0158] In some cases, separate dynamic indications (e.g., separate PDCCH) can be used for new data and retransmissions of hybrid scheduling. For example, if the dynamic indication (e.g., via PDCCH) indicates that data is scheduled, UE 115 can process both new data and retransmissions in the preconfigured occasion, and if UE 115 is configured to receive retransmissions in other time intervals, UE 115 can process retransmissions in other time intervals (e.g., non-preconfigured time intervals). In some examples, retransmissions may not be allowed to be scheduled in the preconfigured occasion. For example, if the dynamic indication indicates that data is scheduled, UE 115 can process new data in the preconfigured occasion, and can process retransmissions in other time intervals where the dynamic indication is monitored.

[0159] In some cases, a dynamic indication (e.g., PDCCH) may not indicate whether retransmission of pre-configured data is scheduled in a time slot. For example, UE 115 may independently monitor unicast dynamic scheduling information (e.g., PDCCH) that schedules the retransmission. In some cases, the dynamic indication may indicate whether a dynamic indication for pre-configured release is sent.

[0160] In some examples, the dynamic indication may include control information in a compact manner to improve system efficiency and reduce decoding resources. The dynamic indication may be scrambled by an RNTI different from the RNTI associated with the dynamic indication that activates the pre-configured scheduling. For example, the RNTI that scrambles the dynamic indication may be a power saving RNTI (PS-RNTI).

[0161] In some examples, the dynamic indication may be sent in a separate CORESET and / or a separate set of search spaces different from the CORESET and / or search space associated with the PDCCH used to activate the pre-configured scheduling.

[0162] The dynamic indication may be monitored at the start of a time interval (e.g., time slot). In some cases, UE 115 may improve resource usage efficiency by avoiding monitoring the dynamic indication outside the start of the time interval. For example, UE 115 may monitor the dynamic indication at the search space set opportunity within the first three symbols of the time interval.

[0163] In some cases, the threshold number (e.g., maximum number) of downlink control channel (e.g., PDCCH) candidates for each aggregation level for the dynamic indication (e.g., PDCCH) may be defined by an RRC search space set configuration. In some cases, the threshold number of downlink control candidates may be an integer (e.g., 1, 2, etc.).

[0164] Figure 6 The figure illustrates an example of a control information message 600 that supports hybrid scheduling techniques in accordance with aspects of the present disclosure. In some examples, the control information message 600 may implement aspects of wireless communication systems 100 and 200. The control information message 600 may illustrate the format and fields included in the downlink control information, which includes dynamic scheduling indications for one or more UEs 115. As such, the control information message 600 may be an example of the dynamic scheduling indication described herein, and the control information message may also be used within a hybrid scheduling scheme to enable efficient communication.

[0165] In some cases, a dynamic indication (e.g., PDCCH) may include (e.g., carry) UE-specific DCI. In some cases, a dynamic indication may include UE group common DCI. For example, multiple UEs 115 may share a dynamic indication, and the dynamic indication may include information for one or more UEs 115. Thus, a control information message included in the dynamic indication may include a common field 605, which is common information for one or more UEs 115 (or for a group of UEs 115). In some cases, a dynamic indication field 610 may indicate whether there is data for the UE 115. In some examples, a content field 615 may indicate the presence of data for the UE 115, or may include UE-specific information, or both. The dynamic indication field 610 may be associated with the content field 615 (e.g., where there may be a mapping between the dynamic indication field 610 and the content field 615), and the content field 615 may include scheduling information for the UE 115 or otherwise be associated with the scheduling information for the UE 115. In some cases, the content field 615 may include other information for the UE 115, such as scheduling parameters that may be used to update or replace a set of previously configured parameters, or may include additional information that the UE 115 may use to send / receive data, or a combination thereof. In some cases, "x" may indicate or otherwise correspond to the number of UEs 115 sharing the same dynamic indication (e.g., PDCCH). In some additional or alternative cases, "Y" may indicate or otherwise correspond to the number of content fields. In some cases, "Y" may be less than or equal to "x".

[0166] In some cases, dynamic indication (e.g., PDCCH, DCI, compact DCI) may include one or more of the following information: time domain resource allocation (TDRA), shift for frequency domain resource allocation (FDRA) (e.g., enabling frequency hopping), physical uplink control channel (PUCCH) resources (e.g., for HARQ-ACK), modulation and coding scheme (MCS), or HARQ feedback timing (e.g., k1 value). Information (e.g., TDRA) may be included or otherwise indicated by the dynamic indication to override information provided by pre-configuration (e.g., TDRA). Thus, the scheduling information provided by the dynamic indication may change the information provided by pre-configuration. In some examples, the information provided by the dynamic indication (e.g., FDRA shift) may be used to update the associated information provided by pre-configuration (e.g., FDRA). Thus, the dynamic indication may increase scheduling flexibility by supporting modification of pre-configured scheduling configurations (e.g., SPS). The control information message 600 may also include a plurality of CRC bits (e.g., CRC 620), which may be scrambled using an RNTI (e.g., PS-RNTI, or some other RNTI that may be used to identify the control information message 600 for one or more UEs 115).

[0167] Figure 7 The figure illustrates an example of a process flow 700 in a system supporting hybrid scheduling techniques according to aspects of the present disclosure. In some examples, the process flow 700 may implement aspects of wireless communication systems 100 and 200. The process flow 700 includes UE 115-d and base station 105-b. These may be examples of the corresponding devices described with reference to Figures 1 to 6 UE 115-d and / or base station 105-b may implement hybrid scheduling techniques, which may reduce UE 115-d power usage and improve communication efficiency. Alternative examples may be implemented, where some steps are performed in a different order than described or not at all. In some cases, steps may include additional functions not mentioned below, or further steps may be added.

[0168] At 705, the base station 105-b may configure a hybrid scheduling configuration that includes a dynamic scheduling indication, a pre-configuration including initial scheduling parameters, and a set of pre-configured timing for communicating data (e.g., the periodicity and offset of time / frequency resources allocated for sending or receiving data). In some examples, the base station 105-b may configure one or more scheduling parameters for one or more UEs 115 (e.g., including UE 115-d), where the one or more scheduling parameters include time domain resource allocation, MCS, HARQ feedback timing, or a combination thereof.

[0169] At 710, base station 105-b may send a dynamic scheduling indication to one or more UEs 115 (e.g., including UE 115-d) based on a set of initial scheduling parameters and preconfigured timing. Additionally or alternatively, base station 105-b may send an indication of periodic and initial scheduling parameters for downlink transmission to one or more UEs 115 (e.g., based on SPS), where the set of preconfigured timing is based on the periodic and initial scheduling parameters for downlink transmission. In other examples, base station 105-b may send an indication of periodic and initial scheduling parameters for uplink transmission to one or more UEs 115 (e.g., based on uplink configured grant), where the set of preconfigured timing is based on the periodic and initial scheduling parameters for downlink transmission.

[0170] At 715, UE 115-d may identify a hybrid scheduling configuration. For example, the hybrid scheduling configuration may include a dynamic scheduling indication (e.g., dynamic indication PDCCH) and preconfigured timing for receiving and / or transmitting data.

[0171] At 720, UE 115-d may monitor the dynamic scheduling indication. For example, UE 115-d may monitor one or more time intervals (e.g., transition time intervals, time slots, frames, subframes, symbols, etc.) for the dynamic scheduling indication. In some examples, the dynamic scheduling indication may be DCI, compact DCI, PDCCH, etc. In some examples, the dynamic indication may be monitored only at the start of a time interval (e.g., time slot).
