[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. 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, improved LTE (LTE-A) systems, or LTE-A Pro systems, and fifth-generation (5G) systems, which may be called New Radio (NR) systems. These systems may employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices, also referred to as User Equipment (UE). In some examples, the UE may support both half-duplex and full-duplex operation. Summary of the Invention

[0068] Some wireless communication systems can support full-duplex operation (e.g., where a user equipment (UE) can transmit and receive simultaneously). Base stations can use downlink control information (DCI) messages to schedule full-duplex operation (e.g., uplink and downlink transmissions that overlap in time). For example, a base station can send a first DCI (e.g., a legacy DCI) to schedule uplink transmissions and a second DCI (e.g., a legacy DCI) to schedule downlink transmissions that overlap with the uplink transmissions in time. To perform full-duplex operation, the UE can adjust one or more parameters to handle overlapping uplink and downlink transmissions. These parameters can include modulation and coding scheme (MCS) tables, transmission configuration indicator (TCI) status, beam configuration or assumptions, power control parameters, system information (SI) and cross-link interference (CLI) measurements, puncturing or rate matching around the demodulation reference signal (DMRS), uplink timing advance (TA) values, etc. Parameters can be set differently for half-duplex and full-duplex operation. Therefore, if the UE fails to receive or decode one of the two DCIs, it will not only be unable to receive or transmit the transmission associated with the failed DCI, but may also send or receive other overlapping transmissions by selecting incorrect parameters. For example, the UE may incorrectly assume that it depends on the uplink / downlink beam correspondence and may select the wrong beam for uplink or downlink transmission. This can lead to multiple failed transmissions or retransmissions, increased system congestion, increased system latency, and a degraded user experience.

[0069] A base station can dynamically and reliably indicate whether pending transmissions are part of full-duplex operation via the DCI design described herein. For example, a base station can transmit a small DCI that includes no more than one downlink grant and no more than one uplink grant for full-duplex operation. In some examples, a base station can transmit a first-stage DCI including partial information, and a second-stage DCI including full uplink and downlink grants for full-duplex operation. In some examples, a base station can configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and can dynamically indicate whether to schedule overlapping uplink and downlink resources for full-duplex operation.

[0070] In some examples, a base station may send a single DCI scheduling one uplink grant and one downlink grant for full-duplex operation. By limiting the number of grants included in a single DCI, the size of the DCI can be limited to increase the likelihood of successful decoding. A DCI may include uplink-specific fields, downlink-specific fields, and shared fields for intensive signaling. In some cases, the UE may use Radio Resource Control (RRC) or Media Access Control (MAC) configuration tables to decode information in the shared fields (which apply to both uplink and downlink transmissions).

[0071] In the second proposal, the base station can transmit a first-stage DCI containing partial information and multiple second-stage DCIs containing additional (e.g., more detailed) information for uplink and downlink transmissions. For example, the first-stage DCI may include resource allocation information for the second-stage DCIs. The UE can easily decode the smaller first-stage DCI, determine that full-duplex operation is pending, and further determine which resources to monitor for receiving the second-stage DCIs (which may include uplink and downlink grants). In some examples, the first-stage DCI may include time-domain resource allocation (TDRA) information for uplink and downlink transmissions, allowing the UE to prepare for switching back and forth between full-duplex and half-duplex operation. The UE can then perform one or more blind decoding procedures on the Physical Uplink Control Channel (PUCCH) candidate to receive the remainder of the uplink and downlink grants (e.g., frequency resource information, etc.).

[0072] In the third proposal, the base station can configure periodic or semi-periodic resources for uplink and downlink transmissions, which may overlap in time. The base station can dynamically indicate whether the overlapping uplink and downlink resources are configured for full-duplex operation. For example, a two-bit indication in the DCI (e.g., one bit for the Physical Uplink Shared Channel (PUSCH) and one bit for the Physical Downlink Shared Channel (PDSCH)) can indicate whether actual transmissions are scheduled for uplink and downlink resources. Alternatively, a one-bit indication in the DCI can indicate whether full-duplex operation is scheduled for overlapping uplink and downlink resources.

[0073] Specific aspects of the subject matter described herein can be implemented to achieve one or more advantages. The described techniques can support improvements in system efficiency, making the UE more likely to successfully decode DCI and accurately identify whether to schedule full-duplex or half-duplex operation. Such improvements in the accuracy of determining the operation type allow the UE to more accurately select transmit or receive parameters, thereby increasing the likelihood of successful transmission, reducing retransmissions and failed transmissions, improving system efficiency, reducing system latency, and improving user experience.

[0074] The aspects of this disclosure are first described in the context of wireless communication systems and timelines. These aspects are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to the design of control channels for dynamic full-duplex enablement, and are described with reference to the aforementioned figures.

UE 115 can be devices of different forms or with different capabilities. Figure 1Some example UE 115s are shown in the document. The UE 115 described herein may be able to communicate with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices). Figure 1 As shown.

[0078] Base station 105 can communicate with core network 130, communicate with each other, or perform both operations. For example, base station 105 can be connected to core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both operations. In some examples, backhaul link 120 can be or includes one or more radio links.

[0079] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNodeB, eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or other suitable terms.

[0080] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or 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, UE 115 may include or 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, and other examples, which may be implemented in various items such as appliances, vehicles, meters, and other examples.

[0081] The UE 115 described in this document may be able to communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0082] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having 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., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0083] In some examples (e.g., in a carrier aggregation configuration), carriers may also have acquisition or control signaling that coordinates operation against other carriers. Carriers may be associated with frequency channels (e.g., Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be positioned according to a channel grid for discovery by UE 115. Carriers may operate in standalone mode, where UE 115 can initiate acquisition and connection via a carrier, or in non-standalone mode, where different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.

[0084] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The 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).

[0085] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of a number of defined bandwidths for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configurable to support communication on one of a set of one or more carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0086] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.

[0087] It can support one or more digital schemes (numerologies) for the carrier, wherein the digital schemes may include subcarrier spacing ( (and cyclic prefix). A carrier can be divided into one or more BWPs with the same or different digital schemes. 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 communication for UE 115 can be restricted to one or more active BWPs.

[0088] It can be in the basic unit of time (which can be, for example, referred to as) The sampling period is seconds, where It can represent the maximum supported subcarrier spacing, and The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0089] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0090] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively or additionally, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).

[0091] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a set of one or more UEs 115. For example, one or more UEs 115 can monitor or search for control regions for control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information in a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.

[0092] 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 used (e.g., on a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish adjacent cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of base station 105, the range of such cells can range from small areas (e.g., structures, subsets of structures) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other examples.

[0093] Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0094] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0095] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0096] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 can be time-disaligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0097] Some UE 115s (e.g., MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can 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 can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115s can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0098] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, when operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs) within a carrier, within a carrier's guard band, or outside a carrier.

[0099] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services such as Mission-Critical Push-to-Talk (MCPTT), Mission-Critical Video (MCVideo), or Mission-Critical Data (MCData). Support for mission-critical functions can include service prioritization, 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 are used interchangeably herein.

[0100] In some examples, UE 115 may also be able to communicate directly with other UE 115s on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UEs 115s utilizing D2D communication may be within the geographic coverage area 110 of base station 105. Other UEs 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UEs 115s communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving base station 105.

[0101] 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., UE 115). In some examples, vehicles may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles may signal information relating to traffic conditions, signal control, weather, safety, emergencies, or any other information relating to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0102] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function unit (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP services 150 for one or more network operators. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0103] Some network devices (e.g., base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0104] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is typically referred to as the UHF region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Transmission of UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 km) compared to transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum, such as the high frequency (HF) or very high frequency (VHF) portions.

[0105] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be even smaller and more closely spaced compared to UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, propagation to EHF transmissions may suffer even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary depending on the country or regulatory authority.

[0106] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.

[0107] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or 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 base station 105 may be located in different geographical locations. Base station 105 may have an antenna array having a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0108] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals 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 used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0109] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide antenna beams (e.g., transmit beams, receive beams) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0110] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.

[0111] Base station 105 may transmit signals (e.g., data signals associated with a specific receiving device, such as UE 115) in a single beam direction. 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 signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or otherwise acceptable signal quality.

[0112] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate combined beams for (e.g., from base station 105 to UE 115) transmissions. UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 can provide feedback on beam selection, which can 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., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0113] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).

[0114] The wireless communication system 100 can 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 can be IP-based. The Radio Link Control (RLC) layer can perform packet fragmentation and reassembly for transmission over logical channels. The MAC layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can 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 RRC protocol layer can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0115] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback in a specific time slot for data received in a previous symbol within the time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0116] Base station 105 can dynamically and reliably indicate whether pending transmissions are part of full-duplex operation via the DCI design described herein. For example, base station 105 can send a DCI to UE 115 including no more than one downlink grant and no more than one uplink grant for full-duplex operation. In some examples, base station 105 can send a first-stage DCI including partial information, and a second-stage DCI including full uplink and downlink grants for full-duplex operation. In some examples, base station 105 can configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and can dynamically indicate to UE 115 whether the overlapping uplink and downlink resources are scheduled for full-duplex operation.

[0117] Figure 2A and Figure 2B Examples of full-duplex scenarios 200 and 201 supporting control channel design for dynamic full-duplex enablement according to various aspects of this disclosure are shown. In some examples, full-duplex scenarios 200 and 201 can implement various aspects of wireless communication system 100. For example, base station 105 and UE 115 can communicate according to full-duplex scenarios 200 and 201.

[0118] In some examples, UE 115 can support full-duplex operation. In full-duplex operation, UE 115 can simultaneously receive downlink transmissions and perform uplink transmissions during one or more symbols supporting full-duplex transmission. Full-duplex operation can be based on a receive-triggered uplink and downlink transmission DCI.

[0119] In some examples, UE 115 can support full-band full-duplex operation, as shown in the reference. Figure 2AAs shown. Base station 105 can schedule downlink data transmission on PDSCH 205-a via a DCI message including downlink permission. PDSCH 205-a can span some or all of the frequency bands in frequency band 215-a. In some examples, base station 105 can also schedule uplink data transmission on PUSCH 210-a via a second DCI message including uplink permission. In some examples, PUSCH 210-a can span some or all of the frequency bands in frequency band 215-a. Therefore, PUSCH 210-a and PDSCH 205-a can overlap in time for at least some symbol periods.

[0120] In some examples, UE 115 can support subband full-duplex operation, as shown in the reference. Figure 2B As shown, base station 105 can schedule a first portion of PDSCH 205-b in a first subband and a second portion of PDSCH 205-b in a second subband of frequency band 215-b via one or more DCI messages including one or more downlink grants. Additionally, base station 105 can schedule PUSCH 210-b in a third subband of frequency band 215-b via another DCI message including uplink grants. Therefore, PUSCH 210-b can overlap with PDSCH 205-b in time for multiple symbol periods.

[0121] In some examples, UE 115 may fail to decode the DCI and may incorrectly prepare for half-duplex operation when scheduling full-duplex operation. Base station 105 may send a first DCI scheduled for PDSCH 205 and a second DCI scheduled for PUSCH 210, which overlaps with PDSCH 205 at least partially in time. If UE 115 receives and successfully decodes both the first and second DCIs, UE 115 can prepare for full-duplex operation based on the overlap between PDSCH 205 and PUSCH 210. However, if UE 115 receives only one of the DCIs, UE 115 may incorrectly determine that a half-duplex operation has been scheduled (either a transmission on PUSCH 210 or a reception on PDSCH 205, but not simultaneously). UE 115 may communicate with base station 105 using half-duplex operation parameters different from those used for full-duplex operation. Such parameters may include MCS tables, TCI status, power control parameters, system information (SI) measurements, CLI measurements, puncturing or rate matching around DMRS, uplink timing advance values, beam indexes, or beam correspondence values, etc. Therefore, if UE 115 receives only one DCI and fails to decode the other, UE 115 can be assumed to be configured for half-duplex operation. It may be ready to perform uplink transmissions on PUSCH 210-b, or ready to receive downlink transmissions on PDSCH 205 using half-duplex parameters (instead of full-duplex parameters). In this case, UE 115 may fail to decode the scheduled downlink transmission, or base station 105 may be unable to receive the scheduled uplink transmission based on a UE using incorrect parameters.

[0122] For example, in half-duplex operation, UE 115 may appropriately assume an uplink / downlink beam mapping and select a transmit or receive beam accordingly. However, in full-duplex operation, UE 115 may not assume an uplink / downlink beam mapping. Base station 105 can determine its receive or transmit beam based on whether UE 115 is configured for full-duplex or half-duplex operation. However, if UE 115 misses a first DCI or a second DCI, UE 115 may assume its uplink / downlink beam mapping and select a beam based on that assumption, while base station 105 assumes that UE 115 cannot depend on the uplink / downlink beam mapping in full-duplex mode and may select a beam based on that assumption. Due to this mismatch in assumptions, UE 115 and base station 105 may select mismatched beams, and uplink or downlink communication may not be received. Therefore, if the scheduling DCI for overlapping downlink and uplink transmissions is lost or difficult to decode, transmissions may fail, latency may increase, and user experience may be affected.

[0123] In some examples, as described herein, base station 105 can use a DCI indicating full-duplex operation to dynamically schedule full-duplex operations. For example, base station 105 can use a single DCI to schedule overlapping uplink and downlink transmissions, the single DCI including a downlink-specific field, an uplink-specific field, and a shared field for both uplink and downlink transmissions, as referenced. Figure 3 As shown. In some examples, base station 105 can use a set of first-stage DCI and one or more second-stage DCI to schedule overlapping uplink and downlink transmissions, as referenced. Figure 4 and Figure 5 In a more detailed description, the first-stage DCI may include indications of resources in which the second-stage DCI is received, or may include indications of time-domain resources for uplink and downlink transmissions so that the UE 115 can prepare antenna arrays, transceivers, etc., to switch between half-duplex and full-duplex operation. In some examples, the base station 105 may configure periodic or semi-periodic uplink and downlink resources, as referenced in [reference missing]. Figure 6 and Figure 7 In more detail, base station 105 can send a DCI indicating whether uplink and downlink resources configured for full-duplex operation overlap.

[0124] Figure 3 Examples of timelines 300 supporting control channel design for dynamic full-duplex enablement according to various aspects of this disclosure are shown. In some examples, timeline 300 can implement various aspects of wireless communication system 100. For example, base station 105 and UE 115 can communicate according to timeline 300.

[0125] In some examples, the UE can use a single Phase 1 DCI to schedule uplink and downlink transmissions. For example, base station 105 can send DCI 305 to allocate one or more resources (e.g., frequency resource 320) of PDSCH 310 and PUSCH 315 for full-duplex operation. In some examples, a first portion of PDSCH 310 may be located on a first subband, and a second portion of PDSCH 310 may be located on a second subband (e.g., between the first and second portions of PUSCH 310). DCI 305 can include uplink permission for uplink transmissions on frequency resource 320 and downlink permission for downlink transmissions on frequency resource 320. Frequency resource 320 may overlap with some or all of the frequency bands of PDSCH 310 and PUSCH 315. In some examples, frequency resource 320 may be a resource block allocated in a symbol by DCI 305.

[0126] In some examples, DCI 305 may be associated with a Radio Network Temporary Identifier (RNTI) specific to this type of DCI. That is, DCI 305 may have a unique design, a unique size, or both for scheduling full-duplex operation. Therefore, DCI 305 may be associated with a unique RNTI used to identify and decode DCI 305. In some examples, base station 105 may send an indication of the RNTI for DCI 305 to UE 115. UE 115 can use the RNTI to decode DCI 305 and determine whether to schedule full-duplex operation on frequency resource 320.

[0127] In some examples, DCI 305 may be associated with a cell RNTI (C-RNTI) assigned by base station 105 and associated with UE 115. In such examples, UE 115 may decode DCI 305 based on the size difference between DCI 305 and other DCIs (e.g., for half-duplex operation). For example, DCI 305 may have a different size than other DCI messages (e.g., it may be larger). DCI 305 may be constrained to schedule no more than one uplink transmission and one downlink transmission on frequency resource 320. Such constraints may reduce the size of DCI 305 (e.g., regarding scheduling multiple uplink transmissions or multiple downlink transmissions) to increase the likelihood that UE 115 will successfully decode DCI 305 and successfully perform full-duplex operation. Therefore, when decoding a DCI based on C-RNTI, UE 115 may utilize multiple size assumptions. That is, UE 115 may assume that DCI 305 is a smaller DCI and may attempt to decode it using C-RNTI. If decoding fails (e.g., if UE 115 does not pass Cyclic Redundancy Check (CRC), UE 115 can attempt to decode DCI 305 using C-RNTI based on the assumption that DCI 305 is large. If decoding succeeds (e.g., if UE 115 passes CRC), UE 115 can correctly identify and prepare for full-duplex operation.

[0128] DCI 305 may include multiple fields. For example, DCI 305 may include one or more downlink fields 330, which include information for downlink transmissions on frequency resource 320. Downlink field 330 may include downlink transmission-specific parameters, such as TCI status. DCI 305 may also include one or more uplink fields 335, which include information for uplink transmissions on frequency resource 320. For example, uplink field 335 may include uplink transmission-specific parameters, such as power control. DCI 305 may also include a shared field 325, which may include information for both uplink and downlink transmissions. Shared field 325 may include one or more parameters that can be used for both uplink and downlink transmissions. For example, uplink and downlink transmissions on frequency resource 320 may utilize overlapping, similar, or identical frequency resources. Therefore, shared field 325 may include indications of frequency domain resource allocation (FDRA) information (e.g., instead of a first FDRA indication for uplink transmissions and a second FDRA indication for downlink transmissions, it may be identical to the first FDRA information). For example, shared field 325 may include a single bandwidth portion (BWP) index indicating the BWP used for both uplink and downlink transmissions. In some examples (e.g., in the case of utilizing subband full-duplex (SBFD) functionality), a single FDRA may be used for the entire uplink and downlink bandwidth (e.g., the full frequency range of frequency resource 320). Similarly, uplink and downlink transmissions may partially or completely overlap in time. Therefore, shared field 325 may include a single indication of time-domain resource allocation (TDRA) information for both uplink and downlink transmissions (e.g., instead of a first TDRA indication for uplink transmissions and a second TDRA indication for downlink transmissions, which may be identical to the first TDRA indication). In some examples, the allocated frequency resources for uplink transmissions and the allocated frequency resources for downlink transmissions may not overlap (e.g., SBFD). In such an example, as indicated by the uplink and downlink bandwidth in the FDRA field and symbol, UE 115 can transmit and receive during the overlap between the resources allocated by the FDRA field and the pre-configured uplink / downlink bandwidth in the indicated symbol.

[0129] The use of the shared field 325 allows for more compact signaling, enabling a smaller DCI 305 size and increasing the likelihood that the UE 115 will be able to successfully receive and decode DCI 305. In some examples, DCI 305 can utilize fields previously used for scheduling two uplink or two downlink transmissions to schedule both uplink and downlink transmissions. In some cases, DCI 305 may not include newly defined or dedicated full-duplex flags because the DCI format may already indicate full-duplex scheduling.

[0130] In some examples, UE 115 may decode shared field 325 based on one or more tables. For example, base station 105 may configure (e.g., via higher-layer signaling such as RRC signaling, Media Access Control (MAC) signaling, or a combination thereof) one or more tables specific to shared field 325. The tables may include entries specific to both uplink and downlink transmissions. Shared field 325 may include one or more values ​​indicating an index on one or more configured tables. UE 115 may use one table to decode shared field 325 and one or more separate tables to decode downlink field 330 and uplink field 335.

[0131] In some examples, as part of full-duplex operation, UE 115 can transmit and receive on frequency resource 320 for full-duplex operation. In some examples, frequency resource 320 allocated by DCI 305 for full-duplex operation may overlap with one or more frequency gaps between PDSCH 310 and PUSCH 315. For example, there may be a guard period in the frequency domain between PDSCH 310 (e.g., on the first subband) and PUSCH 315 (e.g., on the second subband), and another guard period may exist in the frequency domain between PUSCH 315 and PDSCH 310 (e.g., on the first subband). In such examples, UE 115 may ignore frequency resource 320 that overlaps with the guard period. That is, although the FDRA information in shared field 325 may span the entire frequency range of frequency resource 320, UE 115 may ignore (e.g., may avoid transmitting or receiving) the portion of frequency resource 320 that overlaps with the guard period between PDSCH 310 and PUSCH 315.

[0132] Design information for DCI 305 may be known to UE 115 and base station 105 by base station 105 through standardization, pre-configuration, signaling, or other means.

[0133] Figure 4Examples of timelines 400 supporting control channel design for dynamic full-duplex enablement according to various aspects of this disclosure are shown. In some examples, timeline 400 can implement various aspects of wireless communication system 100. For example, base station 105 and UE 115 can communicate according to timeline 300.

[0134] In some examples, base station 105 can use both the first-stage DCI and the second-stage DCI to schedule full-duplex operation. For example, base station 105 can transmit the first-stage DCI 405. In some examples, the first-stage DCI 405 may include resource information associated with the second-stage DCI. For example, the first-stage DCI 405 may include resource information such as time location (e.g., time resource), search space timing indicator (e.g., an indicator for the search space timing to receive the second-stage DCI), aggregation level (AL), the PDCCH candidate index of the second-stage DCI, or any combination thereof. Such information can reduce the decoding complexity of the second-stage DCI.

[0135] The first-stage DCI 405 may be smaller than the size threshold, which may result in reliable decoding of the first-stage DCI 405. The first-stage DCI 405 may include resource information or indications for multiple second-stage DCIs. Each second-stage DCI may schedule a single uplink transmission or a single downlink transmission. Therefore, the first-stage DCI 405 may include downlink DCI information 410 indicating resource information for the second-stage downlink DCI 425, uplink DCI information 415 indicating resource information for the second-stage uplink DCI 430, and downlink DCI information 420 indicating resource information for the second-stage downlink DCI 435. The UE 115 can receive and decode the first-stage DCI 405 and can identify the location for receiving and decoding the second-stage DCIs based on the included DCI information.

[0136] After identifying the resource allocation information for the second-stage DCI by decoding the first-stage DCI 405, the UE 115 can monitor and receive the second-stage DCI. Each second-stage DCI may include a single uplink grant or a single downlink grant. For example, the second-stage downlink DCI 425 may include a downlink grant allocating resources for downlink transmissions on PDSCH 440. The second-stage uplink DCI 430 may include an uplink grant allocating resources for uplink transmissions on PUSCH 450. The second-stage downlink DCI 435 may include a downlink grant allocating resources for downlink transmissions on PDSCH 445. At least a portion of the downlink transmissions on PDSCH 440 and PDSCH 445 may overlap temporally with the uplink transmissions on PUSCH 450. The UE 115 may identify and perform full-duplex operation during the overlapping portion.

[0137] By receiving the relatively small first-stage DCI 405, UE 115 can successfully identify the resource allocation information for each second-stage DCI. UE 115 can then reliably decode the second-stage DCI to receive uplink and downlink grants. Therefore, UE 115 can successfully identify pending full-duplex operations and configure appropriate parameters for such operations.

[0138] In some examples, UE 115 may send feedback information to base station 105, indicating whether UE 115 has successfully received the first-stage DCI 405. The first-stage DCI 405 may include information for constructing the feedback information (e.g., a Hybrid Automatic Repeat Request (HARQ) Acknowledgment (ACK) message or a HARQ Negative ACK (NACK) message). For example, the first-stage DCI 405 may include: resource allocation information for sending the feedback information, a Transmission Time Interval (TTI) offset (e.g., a time slot offset) indicating the offset between the timing of receiving the first-stage DCI 405 and sending the feedback information, etc. UE 115 may successfully decode the first-stage DCI 405 and may send the feedback information (e.g., a HARQ ACK message) on the resources and / or at the time indicated in the first-stage DCI 405.

[0139] In some examples, the first-phase DCI 405 may include resource allocation information for uplink and downlink transmissions, as shown in the reference. Figure 5 More detailed description.

[0140] Figure 5Examples of timelines 500 supporting control channel design for dynamic full-duplex enablement according to various aspects of this disclosure are shown. In some examples, timeline 500 can implement various aspects of wireless communication system 100. For example, base station 105 and UE 115 can communicate according to timeline 500.

[0141] In some examples, base station 105 may transmit a first-stage DCI 505 and one or more second-stage DCIs. The first-stage DCI may include TDRA information for uplink and downlink permissions included in the second-stage DCI. For example, the first-stage DCI 505 may include TDRA information 510-a for downlink transmission on PDSCH 515-a. The first-stage DCI 505 may include TDRA information 510-b for uplink transmission on PUSCH 520. The first-stage DCI 505 may include TDRA information 510-c for downlink transmission on PDSCH 515-b.

[0142] UE 115 can receive a first-stage DCI 505 that includes TDRA information. In some examples, the first-stage DCI 505 may include resource information for one or more second-stage DCIs, which include uplink and downlink permission, as referenced. Figure 5 More detailed description. Alternatively or concurrently, the first-stage DCI 505 may include TDRA information for uplink and downlink transmissions. In such an example, the UE 115 may perform one or more blind decoding procedures in one or more search spaces, PDCCH timings, etc., to identify and receive the second-stage DCI.

[0143] UE 115 can utilize the TDRA information in Phase 1 DCI 505 to prepare for handover between half-duplex and full-duplex operations. For example, a portion of PDSCH 515-a and PUSCH 520 may overlap in time. Similarly, a portion of PDSCH 515-b and PUSCH 520 may overlap in time. However, for the time period between PDSCH 515-a and PDSCH 515-b, PUSCH 520 may not overlap with PDSCH 515. Therefore, UE 115 can perform half-duplex operation during this time period, but can perform full-duplex operation when PUSCH 520 overlaps with PDSCH 515-a and when PUSCH 520 overlaps with PDSCH 515-b. Alternatively, UE 115 can perform full-duplex operation throughout the entire PDSCH or PUSCH period, including the time slot, and when PUSCH 520 overlaps with PDSCH 515-a and when PUSCH 520 overlaps with PDSCH 515-b. If UE 115 is not prepared to switch between half-duplex and full-duplex operation, UE 115 may fail to successfully perform uplink transmissions or receive downlink transmissions. However, UE 115 can identify the timing at which it will switch between half-duplex and full-duplex operation based on the TDRA information included in the first phase DCI505. Based on this identified timing, UE 115 can prepare to perform the handover, which can allow for more reliable transmission and reception during both full-duplex and half-duplex operation.

[0144] In some examples, UE 115 may send feedback information to base station 105, indicating whether UE 115 has successfully received the first-stage DCI 505. The first-stage DCI 505 may include information for constructing the feedback information (e.g., a Hybrid Automatic Repeat Request (HARQ) Acknowledgment (ACK) message or a HARQ Negative ACK (NACK) message). For example, the first-stage DCI 505 may include: resource allocation information for sending the feedback information, a transmission time interval (TTI) offset (e.g., a time slot offset) indicating the offset between receiving the first-stage DCI 505 and the timing for sending the feedback information, etc. UE 115 may successfully decode the first-stage DCI 505 and may send the feedback information (e.g., a HARQ ACK message) on the resources and / or time indicated in the first-stage DCI 505.

[0145] Figure 6Examples of timelines 600 supporting control channel design for dynamic full-duplex enablement according to various aspects of this disclosure are shown. In some examples, timeline 600 can implement various aspects of wireless communication system 100. For example, base station 105 and UE 115 can communicate according to timeline 600.

[0146] In some examples, base station 105 can schedule PDSCH 605 and PUSCH 610 via semi-persistent scheduling (SPS) and can dynamically trigger full-duplex operation via DCI. Base station 105 can configure periodic or semi-periodic resources via higher-layer signaling. For example, base station 105 can configure PDSCH 605-a, PDSCH 605-b, and PDSCH 605-c for potential downlink transmissions. PDSCH 605 can be periodic or semi-periodic. Base station 105 can also configure PUSCH 610-a, PUSCH 610-b, and PUSCH 610-c. PUSCH 610 can be periodic or semi-periodic. In some examples, all or part of at least some PDSCH 605 can overlap in time with part or all of at least some PUSCHs. Therefore, SPS scheduling can indicate potential transmission opportunities in the uplink or downlink. Whether a transmission is actually scheduled to occur can depend on whether there is available data for transmission.

[0147] In some examples, if PDSCH 605 and PUSCH 610 overlap in time, base station 105 can dynamically indicate whether to schedule full-duplex operation on the overlapping transmission timings. For example, base station 105 can send DCI 615 to UE 115. DCI 615 can include one or more indicators of the scheduled transmissions. PDSCH 605-a and PUSCH 610-a may not be indicated by DCI 615. For example, a previously sent DCI message can schedule uplink transmissions on PUSCH 610-a, downlink transmissions on PDSCH 605-a, or both (e.g., however, a single DCI may not dynamically indicate all downlink transmissions and all uplink transmissions on a periodic or semi-periodic transmission timing). Therefore, PDSCH 605-b and PUSCH 610-b, as well as subsequent PDSCH 605 and PUSCH 610, may be available for scheduling DCI 615. UE 115 may have data for transmission after PUSCH 610 occurs during PUSCH 610-b, and base station 105 may identify data for downlink transmission after PDSCH 605-a occurs during PDSCH 605-b. In such an example, base station 105 may include one or more PUSCH indicators and one or more PDSCH indicators in DCI 615. For example, DCI 615 may include PUSCH indicator 620-a and PDSCH indicator 625-a, where PUSCH indicator 620-a may indicate that uplink transmission is scheduled for PUSCH 610-b, and PDSCH indicator 625-a may indicate that downlink transmission is scheduled for PDSCH 605-b.

[0148] In some examples, DCI 615 may include separate indicators for each PDSCH 605 and each PUSCH 610 (e.g., a two-bit indicator for each pair of overlapping transmission timings). Thus, the two-bit indicator can indicate whether PDSCH 705 has scheduled downlink transmissions and whether PUSCH 710 has scheduled uplink transmissions. For example, PUSCH indicator 620-a can be a one-bit indicator that can be turned on to indicate that uplink transmissions are scheduled for PUSCH 6310-b, or turned off to indicate that uplink transmissions are not scheduled for PUSCH 6310-b. PUSCH indicator 620-a and PDSCH indicator 625-a may be included in DCI 615 as a single two-bit indicator in a single field or as two separate indicators in a separate field. In some examples, DCI 615 may include a single one-bit indicator for each pair of overlapping transmission timings, as referenced. Figure 7More detailed description.

[0149] DCI 615 may include only indicators for a subsequent pair of overlapping transmission opportunities (e.g., PDSCH 605-b and PUSCH 610-b) or for a set of one or more subsequent overlapping transmission opportunities (e.g., PDSCH 605-b and PDSCH 605-c, and PUSCH 610-b and PUSCH 610-c, etc.). For example, as described above, DCI 615 may include PUSCH indicator 620-a and PDSCH indicator 625-a. In some examples, DCI 615 may also include PUSCH indicator 620-b, which may indicate that no uplink transmission is scheduled for PUSCH 6110-c, and may also include PDSCH indicator 625-b, which may indicate that downlink transmission is scheduled for PDSCH 605-c. In such an example, UE 115 can determine to schedule full-duplex operation during PDSCH 605-b and PUSCH 610-b, and half-duplex operation during PDSCH 605-c and PUSCH 610-c. In this example, UE 115 can select appropriate parameter values ​​(e.g., MCS, TCI state, beam selection, etc.) for full-duplex operation, and appropriate parameter values ​​for half-duplex operation.

[0150] In some examples, the DCI 615 may also include updated scheduling information for subsequent transmission timing. For example, the DCI 615 may provide indicators for PDSCH 605-b and PUSCH 610-b, and may include parameters (e.g., MCS, TCI status, power control parameters, etc.) for updates to PDSCH 605-c and PUSCH 610-c.

[0151] In some examples, UE 115 may send feedback information to base station 105 indicating whether UE 115 has successfully received DCI 615. DCI 615 may include information for constructing the feedback information (e.g., a Hybrid Automatic Request (HARQ) Acknowledgment (ACK) message or a HARQ Negative ACK (NACK) message). For example, DCI 615 may include resource allocation information for sending the feedback information, a Transmission Time Interval (TTI) offset (e.g., a time slot offset) indicating the offset between the timing of receiving DCI 615 and the timing used to send the feedback information, etc. UE 115 may successfully decode DCI 615 and may send the feedback information (e.g., a HARQ ACK message) on resources and / or at the timing indicated in DCI 615.

[0152] Figure 7Examples of timelines 700 supporting control channel design for dynamic full-duplex enablement according to various aspects of this disclosure are shown. In some examples, timeline 700 can implement various aspects of wireless communication system 100. For example, base station 105 and UE 115 can communicate according to timeline 700.

[0153] In some examples, base station 105 can schedule PDSCH 705 and PUSCH 710 via semi-persistent scheduling (SPS) and can dynamically trigger full-duplex operation via DCI. Base station 105 can configure periodic or semi-periodic resources via higher-layer signaling. For example, base station 105 can configure PDSCH 705-a, PDSCH 705-b, and PDSCH 705-c for potential downlink transmissions. PDSCH 705 can be periodic or semi-periodic. Base station 105 can also configure PUSCH 7-a, PUSCH 710-b, and PUSCH 710-c. PUSCH 710 can be periodic or semi-periodic. In some examples, at least some of PDSCH 705 may overlap in time with at least some of PUSCH 710. Therefore, SPS scheduling can indicate the timing of potential transmissions in the downlink or uplink. Whether a transmission is actually scheduled to occur may depend on whether data is available for transmission.

[0154] In some examples, if PDSCH 705 and PUSCH 710 overlap in time, base station 105 can dynamically indicate whether to schedule full-duplex operation during the overlapping transmission periods. For example, base station 105 can send DCI 715 to UE 115. DCI 715 may include one or more indicators of the scheduled transmissions. DCI 715 may not indicate PDSCH 705-a and PUSCH 710-a. For example, a previously sent DCI message may schedule uplink transmissions on PUSCH 710-a, downlink transmissions on PDSCH 705-a, or both (e.g., however, a single DCI may not dynamically indicate all downlink transmissions and all uplink transmissions during periodic or semi-periodic transmission periods). Therefore, PDSCH 705-b and PUSCH 710-b, as well as subsequent PDSCH 605 and PUSCH 610, may be available for scheduling by DCI 615. UE 115 may have data for transmission during PUSCH 710-b after PUSCH 710-a, and base station 105 may identify data for downlink transmission during PDSCH 705-b after PDSCH 705-a. In such an example, base station 105 may include one or more operation type indicators 720 in DCI 715. For example, DCI 715 may include operation type indicator 720-a, which may indicate scheduling of full-duplex operation for overlapping transmission timing 725-a. For example, operation type indicator 720-a may be a one-bit indicator that can be turned on to indicate overlapping uplink and downlink transmissions scheduled on PUSCH 710-b and PDSCH 705-b respectively, or the indicator can be turned off to indicate that no overlapping uplink and downlink transmissions are scheduled on PUSCH 710-b and PDSCH 705-b. UE 115 can receive DCI and, based on the operation type indicator -a, determine whether to schedule uplink transmissions on PUSCH 710-b and downlink transmissions on PDSCH 705-b. Therefore, UE 115 can select the appropriate parameters for performing full-duplex operation.

[0155] In some examples, DCI 715 may include only an indicator for a subsequent pair of overlapping transmission opportunities (e.g., PDSCH 705-b and PUSCH 710-b), or an indicator for a set of one or more subsequent overlapping transmission opportunities (e.g., PDSCH 705-b and PDSCH 705-c, and PUSCH 710-b and PUSCH 710-c, etc.). For example, as described above, DCI 715 may include an operation type indicator 720-a. In some examples, DCI 715 may also include an operation type indicator 720-b, which may indicate that full-duplex operation is not scheduled during the overlapping transmission period 725-b. For example, base station 105 may schedule downlink transmissions during PDSCH 705-d, but UE 115 may not be scheduled for uplink transmissions on PUSCH 710-c. In such an example, operation type indicator 720-b may indicate that half-duplex operation is scheduled during the overlapping transmission period 725-b. In such an example, UE 115 can select appropriate parameter values ​​for full-duplex operation (e.g., MCS, TCI state, beam selection, etc.) and appropriate parameter values ​​for half-duplex operation.

[0156] In some examples, UE 115 may send feedback information to base station 105, the feedback message indicating whether UE 115 has successfully received DCI 715. DCI 715 may include information for constructing the feedback information (e.g., a Hybrid Automatic Request (HARQ) Acknowledgment (ACK) message or a HARQ Negative ACK (NACK) message). For example, DCI 715 may include resource allocation information for sending the feedback information, a transmission time interval (TTI) offset (e.g., a time slot offset) indicating the offset between the timing of receiving DCI 715 and the timing for sending the feedback information, etc. UE 115 may successfully decode DCI 715 and may send the feedback information (e.g., a HARQ ACK message) on resources and / or at the timing indicated in DCI 715.
