[0001] Cross - Reference to Related Applications

[0002] This patent application claims priority to the following applications: U.S. Provisional Patent Application No. 63 / 040,814, filed on June 18, 2020, entitled "DOWNLINK CONTROL INFORMATION FOR FREQUENCY DOMAIN SLOT FORMAT INDICATION"; and U.S. Non - Provisional Patent Application No. 17 / 302,950, filed on May 17, 2021, entitled "DOWNLINK CONTROL INFORMATION FOR FREQUENCY DOMAIN SLOT FORMAT INDICATION", which are hereby incorporated by reference in their entirety. Field of Technology

[0003] Aspects of the present disclosure generally relate to wireless communications, and to techniques and apparatus for downlink control information for frequency - domain slot format indication. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple - access technology capable of supporting communication with multiple user equipment (UE) by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple - access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single - Carrier Frequency Division Multiple Access (SC - FDMA) systems, Time - Division Synchronous Code Division Multiple Access (TD - SCDMA) systems, and Long - Term Evolution (LTE). LTE / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standards released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include a number of base stations (BS) capable of supporting communication for multiple user equipment (UE). The UE may communicate with the BS via a downlink and an uplink. The "downlink" (or "forward link") refers to the communication link from the BS to the UE, and the "uplink" (or "reverse link") refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit - receive point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the urban, national, regional, and even global levels. NR (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectral efficiency, reducing costs, enhancing services, leveraging new spectrums, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the Downlink (DL), and CP-OFDM and / or SC-FDM (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the Uplink (UL), as well as supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technology, and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other radio access technologies remain useful. SUMMARY OF THE INVENTION

[0027] Aspects of the present disclosure are more fully described below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout the present disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should appreciate that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or in combination with any other aspect of the present disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the present disclosure is intended to cover such an apparatus or method implemented using other structures, functions, or a combination of structures and functions in addition to or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0028] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"), and illustrated in the accompanying drawings. These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0029] It should be noted that although terms commonly associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0030] Figure 1FIG. is a schematic diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include a 5G (NR) network and / or an LTE network and elements of other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographical area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0031] The BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographical area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs with a service subscription. A pico cell may cover a relatively small geographical area and may allow unrestricted access by UEs with a service subscription. A femto cell may cover a relatively small geographical area (e.g., a residence) and may allow restricted access by UEs associated with that femto cell (e.g., UEs in a closed subscriber group (CSG)). The BS for a macro cell may be referred to as a macro BS. The BS for a pico cell may be referred to as a pico BS. The BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0032] In some aspects, a cell may not necessarily be stationary, and the geographical area of a cell may move according to the location of a moving BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transmission network.

[0033] The wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that is capable of relaying transmissions for other UEs. In Figure 1 the example shown in, the relay BS 110d can communicate with the macro BS 110a and the UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS can also be referred to as a relay station, a relay base station, a repeater, etc.

[0034] The wireless network 100 can be a heterogeneous network that includes different types of BSs (such as macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS can have a high transmit power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0035] The network controller 130 can be coupled to a set of BSs and can provide coordination and control for these BSs. The network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0036] The UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a user unit, a station, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0037] Some UEs can be considered as Machine-Type Communication (MTC) or evolved or enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node can provide a connection to or from a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link, for example. Some UEs can be considered as Internet of Things (IoT) devices, and / or can be implemented as NarrowBand IoT (NB-IoT) devices. Some UEs can be considered as Customer Premises Equipment (CPE). The UE 120 can be included inside a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some aspects, the processor component and the memory component can be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a particular RAT and can operate on one or more frequencies. The RAT can also be referred to as a radio technology, an air interface, etc. The frequency can also be referred to as a carrier, a frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0039] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediary for communicating with each other). For example, the UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), and / or a mesh network. In such cases, the UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0040] Devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2) that can span from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "sub-6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise explicitly stated, it should be understood that the term "sub-6 GHz", etc. (if used herein) can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the term "millimeter wave", etc. (if used herein) can broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is expected that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein can be applied to those modified frequency ranges.

[0041] As noted above, Figure 1 is provided as an example. Other examples may be different from those Figure 1 described.

[0042] Figure 2 is a schematic diagram showing an example of a base station 110 communicating with a UE 120 in the wireless network 100 according to the present disclosure. The base station 110 can be equipped with T antennas 234a to 234t, and the UE 120 can be equipped with R antennas 252a to 252r, where generally, T≥1 and R≥1.

[0043] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCSs) for a UE at least in part based on channel quality indicators (CQIs) received from each UE, process (e.g., encode and modulate) the data for the UE at least in part based on the MCSs selected for each UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs) or demodulation reference signals (DMRSs)) and synchronization signals (e.g., primary synchronization signals (PSSs) or secondary synchronization signals (SSSs)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0044] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signals to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection (if applicable) on the received symbols, and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or channel quality indicator (CQI) parameters, among other examples. In some aspects, one or more components of the UE 120 may be included within the housing 284.

[0045] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0046] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include or may be included within the following: one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include a coplanar set of antenna elements and / or a non-coplanar set of antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include antenna elements within a single housing and / or antenna elements within multiple housings. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components) of

[0047] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 (if applicable), further processed by the modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in the modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and the memory 282 to perform aspects of any of the methods described herein (e.g., as referenced Figures 7 - 9 described).

[0048] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communication. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in the modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of the antenna 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and the memory 242 to perform aspects of any of the methods described herein (e.g., as referenced Figures 7 - 9 described).

[0049] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component in may perform one or more techniques associated with downlink control information (DCI) for frequency domain slot format indication, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 any other component in may perform or direct the operation of, for example Figure 8 process 800, Figure 9 process 900, and / or other processes as described herein. The memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions for wireless communication (e.g., code and / or program code). For example, when one or more instructions are executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), the one or more processors, UE 120, and / or base station 110 may be caused to perform or direct the operation of, for example Figure 8 process 800, Figure 9 process 900, and / or other processes as described herein. In some aspects, executing the instructions may include running the instructions, converting the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.

[0050] In some aspects, UE 120 may include units for receiving (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.) from the base station DCI including multiple frequency domain slot format indications (SFI); units for communicating with the base station (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, etc.) at least in part based on the frequency domain SFI among the multiple frequency domain SFIs, etc. In some aspects, such units may include one or more components of UE 120 described in conjunction with Figure 2 such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0051] In some aspects, the base station 110 may include units for transmitting to the UE (e.g., using the controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, memory 242, etc.) DCI including multiple frequency-domain SFIs; units for communicating with the UE at least in part based on the frequency-domain SFI among the multiple frequency-domain SFIs (e.g., using the controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, etc.). In some aspects, such units may include one or more components of the base station 110 described in conjunction with Figure 2 such as the antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0052] Although Figure 2 the boxes in are shown as distinct components, the functions described above with respect to the boxes may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0053] As noted above, Figure 2 is provided as an example. Other examples may be different from the example described with respect to Figure 2

[0054] Figures 3A - 3C is a schematic diagram showing examples 300, 320, 340 of full-duplex (FD) communication according to the present disclosure. FD communication may include simultaneous uplink and downlink communication. For example, the uplink and downlink communication may at least partially overlap in time.

[0055] Figure 3A Example 300 of includes UE1 302 and two base stations (e.g., TRPs) 304-1, 304-2, where UE1 302 is transmitting a UL transmission to base station 304-1 and receiving a DL transmission from base station 304-2. In Figure 3A ​In Example 300, FD is enabled for UE1 302, and FD is not enabled for base stations 304-1 and 304-2 (for example, half-duplex (HD) communication is enabled for base stations 304-1 and 304-2). In addition, as indicated by reference numeral 306, UL transmissions to base station 304-1 may self-interfere with DL transmissions from base station 304-2. This may be caused by various factors such as the transmission power used for UL transmissions (compared to DL transmissions), radio frequency bleeding, etc.

[0056] Figure 3B Example 320 includes two UEs (UE1 302-1 and UE2 302-2) and a base station 304, where UE1 302-1 is receiving DL transmissions from base station 304, and UE2 302-2 is sending UL transmissions to base station 304. In Figure 3B In Example 320, FD is enabled for base station 304, and FD is not enabled for UE1 302-1 and UE2 302-2 (for example, HD communication is enabled for UE1 302-1 and UE2 302-2). In addition, as indicated by reference numeral 308, DL transmissions from base station 304 to UE1 302-1 may self-interfere with UL transmissions from UE2 302-2 to base station 304.

[0057] Figure 3C Example 340 includes UE1 302 and base station 304, where UE1 302 is receiving DL transmissions from base station 304, and UE1 302 is sending UL transmissions to base station 304. In Figure 3C In Example 340, FD is enabled for both UE1 302 and base station 304. In addition, as indicated by reference numeral 310, UL transmissions to base station 304 may self-interfere with DL transmissions from base station 304.

[0058] As noted above, Figures 3A - 3C is provided as an example. Other examples may be different from the examples described with respect to Figures 3A - 3C

[0059] Figures 4A - 4C is a schematic diagram showing various duplex modes in a radio access network according to the present disclosure. Figure 4A ​Depicts the time-division duplex (TDD) communication mode between a UE and a base station. In TDD, only one endpoint (e.g., one of the UE or the base station) can send information to the other endpoint (e.g., the other of the UE or the base station) at a time. For example, in TDD, transmissions in different directions on a given channel are separated from each other using time-division multiplexing. That is, at some times, the channel is dedicated to transmission in one direction, while at other times, the channel is dedicated to transmission in the other direction. In some cases, the direction may change rapidly, such as several times per time slot. Thus, as Figure 4A shown, DL communication 402 is separated from UL communication 404 in time.

[0060] Figure 4B Depicts the frequency-division duplex (FDD) communication mode between a UE and a base station. In FDD, the two endpoints can communicate with each other simultaneously at different frequencies (e.g., different frequency bands, sets of subcarriers, resource blocks, etc.). In the FDD mode, as Figure 4B shown, transmissions in different directions operate at different carrier frequencies. Thus, as Figure 4B shown, DL communication 402 is separated from UL communication 404 in frequency, as indicated by the guard band. In some cases, FDD may be referred to as full duplex because a wireless communication device may be able to transmit and receive simultaneously, where the transmission uses a first frequency and the reception uses a second frequency. Since the simultaneous transmission and reception performed by a device in FDD use different frequencies, this full duplex mode may be referred to as sub-band FDD (or flexible duplex).

[0061] Figure 4C Describes the true FD communication mode between a UE and a base station. In the true FD mode, as Figure 4C shown, transmissions in different directions operate at the same carrier frequency or within an overlapping bandwidth. In the example shown in Figure 4C DL communication 402 overlaps with UL communication 404 (e.g., partially or fully) in both time and frequency. Thus, when operating in the true FD mode, the UE and the base station are configured for concurrent transmission and reception within an overlapping bandwidth. That is, in this mode, the simultaneous transmission and reception performed by a device can use the same frequency. As a result, this FD mode may be referred to as in-band FD.

[0062] As pointed out above, Figures 4A - 4C is provided as an example. Other examples may be different from the example described with respect to Figures 4A - 4C .

[0063] Figure 5 is a schematic diagram showing an example of an FDD configuration according to the present disclosure. Figure 5An example of a time interval 510 (e.g., a time slot, a group of time slots, a subframe, a sub - time slot, a micro - time slot, etc.) is shown. The time interval can include an uplink frequency region, a downlink frequency region, or both an uplink frequency region and a downlink frequency region. Each time interval can be associated with a control region (shown as the darker shaded part of the time interval) and / or a data region (shown as DL data for the downlink frequency region or a physical uplink shared channel (PUSCH) for the uplink frequency region). The uplink frequency region is shown using a more closely dotted - line filling than the downlink frequency region.

[0064] An FDD configuration can indicate one or more downlink frequency regions and one or more uplink frequency regions. For example, an FDD configuration can divide an unpaired frequency band (e.g., one or more component carriers of an unpaired frequency band) into an uplink frequency region, a downlink frequency region, and / or other regions (e.g., guard bands, etc.). The uplink frequency region and the downlink frequency region can be equal or unequal in bandwidth. In some aspects, an FDD configuration can identify bandwidth part (BWP) configurations corresponding to the uplink frequency region and the downlink frequency region. For example, respective BWPs can be configured for each uplink frequency region and each downlink frequency region. FDD can increase throughput and improve spectral efficiency, and can enable the use of an always - on uplink (e.g., for a ultra - reliable low - latency communication (URLLC) control channel).

[0065] As Figure 5 Further shown, a base station (or UE) can include multiple antenna panels (e.g., antenna port groups), shown as panel 1 and panel 2. The multiple antenna panels can enable simultaneous transmit (Tx) and receive (Rx) operations. In addition, the multiple antenna panels can provide improved isolation for simultaneous transmit and receive operations.

[0066] In some cases, as Figure 5 shown, a base station (or UE) can switch between an FD mode and an HD mode on a time - slot - to - time - slot basis. As an example, in an HD downlink time interval (e.g., a time slot), the base station can use panel 1 and panel 2 to transmit a downlink transmission. In an FD time interval, the base station can use panel 1 to transmit a downlink transmission and use panel 2 to receive an uplink transmission. In an HD uplink time interval, the base station can use panel 1 and panel 2 to receive an uplink transmission.

[0067] As shown by reference numeral 520, in the FD mode, downlink communication (e.g., on panel 1) can use the edges of the frequency band, and uplink communication (e.g., on panel 2) can use the middle region of the frequency band (e.g., between the edges). However, as shown, frequency leakage of the uplink communication may cause interference with the downlink communication (which may be a problem for the UE), and frequency leakage of the downlink communication may cause interference with the uplink communication (which may be a problem for the base station).

[0068] The base station (or UE) can perform various techniques for canceling or eliminating self-interference, such as antenna isolation (as described above, using physically separated antennas for transmission or reception), analog interference cancellation, digital interference cancellation, beamforming nulling based on massive MIMO (M-MIMO) for clutter reflection, and sub-band FD, to achieve isolation based at least in part on adjacent channel leakage ratio (ACLR), etc. In sub-band FD, the downlink and uplink are in different parts of the frequency band or component carrier, as described above. A guard band (GB) can be provided between the uplink and the downlink. A receive weighted overlap and add (WOLA) operation can reduce the ACLR leakage to the uplink signal. An analog low-pass filter can improve the dynamic range of the analog-to-digital converter (ADC).

[0069] As pointed out above, Figure 5 is provided as an example. Other examples may be different from the example regarding Figure 5 described.

[0070] Figure 6 is a schematic diagram showing an example of a time-domain slot format indication according to the present disclosure. As Figure 6 shown, the UE can receive DCI (e.g., UE group common DCI, such as in DCI format 2_0) including a plurality of time-domain slot format indications (SFI, which may also be referred to as a slot format indicator). The UE can also receive (e.g., before receiving the DCI) a configuration for a position-in-DCI (e.g., PositionInDCI) value in the DCI, and the UE will use this position value in the DCI to determine the time-domain SFI from among the plurality of time-domain SFIs. That is, the UE can use this position value in the DCI to determine the position in the DCI associated with the time-domain SFI to be used by the UE 120. For example, as Figure 6 shown, the position value in the DCI can indicate to use SFI 5.

[0071] Each time-domain SFI can be associated with a respective slot format combination identifier (e.g., SlotFormatCombinationID). For example, SFI 5 can be mapped to slot format combination identifier 3. Additionally, a UE can be configured with multiple time-domain configurations for one or more slots (or other time intervals), and each slot format combination identifier can be mapped to a respective time-domain configuration among the multiple time-domain configurations. For example, as Figure 6 shown, slot format combination identifier 3 can be mapped to slot format 0, slot format 56, and slot format 1, which indicates the time-domain configurations for three slots. In some aspects, the time-domain configuration for one or more slots can identify the symbols for uplink (U) communication, downlink (D) communication, or flexible (F) communication (e.g., uplink or downlink).

[0072] In some cases, the time-domain SFI can indicate the time-domain configuration for configuring one or more slots for FD communication. However, current wireless networks may lack a mechanism to indicate in DCI the FD frequency-domain configuration to be used for FD slots. Some of the techniques and apparatuses described herein provide DCI that includes multiple frequency-domain SFIs respectively associated with FD frequency-domain configurations. In this way, the UE can determine the frequency-domain SFI among the multiple frequency-domain SFIs to be used for one or more FD slots.

[0073] As pointed out above, Figure 6 is provided as an example. Other examples may be different from the example regarding Figure 6 described.

[0074] Figure 7 is a schematic diagram showing an example 700 of DCI for frequency-domain slot format indication according to the present disclosure. As Figure 7 shown, the base station 110 and the UE 120 can communicate with each other. In some aspects, the UE 120 may be capable of operating in the FD mode (e.g., FD UE). In some aspects, the UE 120 may not be capable of operating in the FD mode, but may know about FD operation, FD slots, etc. (e.g., FD-aware UE). In some aspects, the UE 120 may be capable of operating in the HD-FDD mode, whereby the UE 120 can perform only one of uplink communication or downlink communication in the FD slot.

[0075] As indicated by reference numeral 705, base station 110 may transmit and UE 120 may receive one or more FD frequency domain configurations 725, 730. The FD frequency domain configuration may indicate a frequency domain slot format for one or more FD time slots. For example, the FD frequency domain configuration may identify the frequency positions in one or more FD time slots of one or more uplink frequency bands and one or more downlink frequency bands (e.g., spanning carrier bandwidth, channel bandwidth, component carrier (CC) bandwidth (BW), etc.). Additionally, the FD frequency domain configuration may identify the frequency positions of one or more guard bands between one or more uplink frequency bands and one or more downlink frequency bands.

[0076] As Figure 7 shown, each FD frequency domain configuration may be associated with a respective slot frequency combination identifier (e.g., SlotFreqCombinationID). Additionally, each slot frequency combination identifier may be associated with a respective frequency domain SFI, as described below.

[0077] As described above, UE 120 may also receive from base station 110 one or more time domain configurations. As described above, each time domain configuration may be associated with a respective slot format combination identifier.

[0078] In some aspects, one or more frequency domain configurations and / or one or more time domain configurations may be radio resource control (RRC) configured for UE 120. That is, base station 110 may transmit one or more frequency domain configurations and / or one or more time domain configurations via RRC signaling, and UE 120 may receive one or more frequency domain configurations and / or one or more time domain configurations via RRC signaling.

[0079] As indicated by reference numeral 710, base station 110 may transmit and UE 120 may receive a DCI position configuration for DCI including a frequency domain SFI (which may be referred to herein as frequency domain DCI). In some aspects, the DCI position configuration may include information identifying a position value in the DCI for the frequency domain DCI (e.g., FreqpositionDCI). The position value in the DCI identifies the position in the DCI associated with the SFI to be used by UE 120 (e.g., identifies which frequency domain SFI among multiple frequency domain SFIs in the DCI that UE 120 is to follow).

[0080] As described above, UE 120 may also receive from base station 110 a DCI position configuration for DCI including a time domain SFI (which may be referred to herein as time domain DCI). In some aspects, the DCI position configuration may include information identifying a position value in the DCI for the time domain DCI (e.g., PositionInDCI), as described above.

[0081] In some aspects, the DCI location configuration for frequency-domain DCI and / or the DCI location configuration for time-domain DCI is DCI, media access control control element (MAC-CE), or RRC configured for UE 120. That is, the base station 110 can send via DCI, MAC-CE, or RRC signaling and the UE 120 can receive via DCI, MAC-CE, or RRC signaling the DCI location configuration for frequency-domain DCI and / or the DCI location configuration for time-domain DCI.

[0082] As shown by reference number 715, the base station 110 can send DCI and the UE 120 can receive DCI. In some aspects, the base station 110 can send time-domain DCI (e.g., UE group common DCI, such as in DCI format 2_0). The time-domain DCI can include multiple time-domain SFIs. As described above, the time-domain SFI can be mapped to a time slot format combination identifier indicating the time-domain configuration. In some aspects, the base station 110 can send frequency-domain DCI (e.g., UE group common DCI, such as in a DCI format referred to herein as DCI format 2_x). The frequency-domain DCI can include frequency-domain information, such as multiple frequency-domain SFIs. As described above, the frequency-domain SFI can be mapped to a time slot frequency combination identifier indicating the frequency-domain configuration.

[0083] In some aspects, if the UE 120 is an FD UE or an FD-aware UE, the UE 120 can monitor and receive both time-domain DCI and frequency-domain DCI. In some aspects, if the UE 120 is operating in HD mode (e.g., HD UE), the UE 120 can monitor and receive only time-domain DCI.

[0084] In some aspects, the time-domain DCI and the frequency-domain DCI can be associated with different radio network temporary identifiers (RNTIs) (e.g., scrambled by different RNTIs). Thus, the UE 120 can use a first RNTI to receive the time-domain DCI and a second RNTI (e.g., SFI-freq-RNTI) to receive the frequency-domain DCI.

[0085] In some aspects, the time-domain DCI and the frequency-domain DCI can be associated with the same period. That is, the UE 120 can monitor the frequency-domain DCI at the same period as the period used by the UE 120 for monitoring the time-domain DCI. In some aspects, the time-domain DCI and the frequency-domain DCI can be associated with different periods. That is, the UE 120 can monitor the frequency-domain DCI at a period different from the period used by the UE 120 for monitoring the time-domain DCI.

[0086] In some aspects, time-domain DCI and frequency-domain DCI can be associated with different physical downlink control channel (PDCCH) monitoring occasions. That is, UE 120 can use a first set of PDCCH monitoring occasions to monitor for time-domain DCI, and use a second set of PDCCH monitoring occasions to monitor for frequency-domain DCI. For example, this can be useful when the frequency-domain SFI for UE 120 is updated less frequently than the time-domain SFI for UE 120.

[0087] In some aspects, the PDCCH monitoring occasions for frequency-domain DCI can be independent of the PDCCH monitoring occasions for time-domain DCI (e.g., not related to the PDCCH monitoring occasions for time-domain DCI). For example, UE 120 can receive separate PDCCH monitoring configurations for time-domain DCI and for frequency-domain DCI.

[0088] In some aspects, the PDCCH monitoring occasions for frequency-domain DCI can be offset in time and / or frequency relative to the PDCCH monitoring occasions for time-domain DCI. For example, UE 120 can receive a PDCCH monitoring configuration for time-domain DCI, and can use a time offset and / or a frequency offset relative to the PDCCH monitoring configuration for time-domain DCI to determine the PDCCH monitoring configuration for frequency-domain DCI.

[0089] In some aspects, the PDCCH monitoring occasions for time-domain DCI and for frequency-domain DCI can be the same. For example, UE 120 can monitor for time-domain DCI and for frequency-domain DCI in the same PDCCH monitoring occasion according to the PDCCH monitoring configuration for time-domain DCI (or the PDCCH monitoring configuration for frequency-domain DCI).

[0090] In some aspects, UE 120 may be operating in the HD-FDD mode. In some aspects (e.g., when UE 120 is operating in the HD-FDD mode), UE 120 can monitor (e.g., can be configured to monitor) the PDCCH monitoring occasions for frequency-domain DCI regardless of whether the time-domain SFI of the time-domain DCI previously received by UE 120 indicates a time-domain configuration with FD time slots. In this case, the time-domain DCI can indicate (e.g., according to the indicated time-domain configuration) the time slots to be used for the uplink and / or the time slots to be used for the downlink. In addition, the frequency-domain DCI can indicate (e.g., according to the indicated FD frequency-domain configuration) the downlink frequency position (e.g., downlink band position) for the time slots to be used for the downlink and indicate the uplink frequency position (e.g., uplink band position) for the time slots to be used for the uplink.

[0091] In some aspects (e.g., when the UE 120 is operating in the HD-FDD mode), the UE 120 may monitor (e.g., may be configured to monitor) the PDCCH monitoring occasion for the frequency-domain DCI only when the time-domain SFI of the time-domain DCI previously received by the UE 120 indicates a time-domain configuration with FD time slots. In this case, the time-domain DCI may indicate (e.g., according to the indicated time-domain configuration) one or more FD time slots, and the UE 120 may determine that the indicated FD time slots will be used for HD-FDD. Additionally, the frequency-domain DCI may indicate (e.g., according to the frequency-domain configuration) the FD time slots to be used for uplink communication or for downlink communication (e.g., to be used for HD-FDD).

[0092] In some aspects, the UE 120 may decode the time-domain DCI received by the UE 120 and use the DCI position configuration for the time-domain DCI to determine the time-domain SFI included in the time-domain DCI among the plurality of time-domain SFIs. The UE 120 may determine the time-domain configuration to be used at least in part based on the determined time-domain SFI (e.g., as described above, the time-domain SFI may be mapped to a specific time-domain configuration). In some aspects, the time-domain configuration may indicate one or more FD time slots.

[0093] In some aspects, the time-domain DCI and the frequency-domain DCI may have a time offset (e.g., the periods of the time-domain DCI and the frequency-domain DCI may be according to the time offset), and this time offset enables the decoding of the time-domain DCI before receiving the frequency-domain DCI. For example, the time offset between the PDCCH monitoring occasion for the time-domain DCI and the PDCCH monitoring occasion for the frequency-domain DCI may be greater than the amount of time required to decode the time-domain DCI.

[0094] In this way, the UE 120 may determine whether the time-domain SFI of the time-domain DCI indicates FD time slots before the PDCCH monitoring occasion for the frequency-domain DCI, and may monitor the PDCCH monitoring occasion for the frequency-domain DCI at least in part based on whether the time-domain SFI indicates FD time slots. For example, if the previous time-domain SFI does not indicate FD time slots, the UE 120 may skip the PDCCH monitoring occasion for the frequency-domain DCI, thereby saving network resources, UE processing resources, etc. Thus, if the time-domain SFI of the time-domain DCI does not indicate FD time slots, the UE 120 may skip the PDCCH monitoring occasion for the frequency-domain DCI until the UE 120 receives a time-domain SFI indicating FD time slots. Alternatively, if the UE 120 successfully decodes the time-domain DCI indicating the time-domain SFI (which indicates FD time slots), the UE 120 may monitor the next PDCCH monitoring occasion for the frequency-domain DCI (e.g., to determine the frequency-domain configuration for the FD time slots).

[0095] In some aspects, the UE 120 may decode the frequency-domain DCI received by the UE 120 and use the DCI location configuration for the frequency-domain DCI to determine the frequency-domain SFI included in the frequency-domain DCI among multiple frequency-domain SFIs. The UE 120 may determine the FD frequency-domain configuration to be used at least in part based on the determined frequency-domain SFI (e.g., the frequency-domain SFI may be mapped to a specific FD frequency-domain configuration as described above). The FD frequency-domain configuration may be associated with one or more FD time slots indicated by the time-domain configuration (e.g., for one or more FD time slots indicated by the time-domain configuration) as described above.

[0096] In some aspects, the decoding of the frequency-domain DCI at the UE 120 may fail. In particular, the time-domain SFI may indicate at least one FD time slot, but due to the failure to decode the frequency-domain DCI, the UE 120 may not be able to determine the frequency-domain configuration for the FD time slot. In some aspects (e.g., when the UE 120 fails to decode the frequency-domain DCI), the UE 120 may determine that the FD time slot will be used for HD communication (e.g., the FD time slot will be an HD time slot) according to a fixed communication indication (e.g., a fixed communication indication configured for the UE 120). For example, the UE 120 may determine that the FD time slot is a downlink time slot (e.g., all downlink symbols), an uplink time slot (e.g., all uplink symbols), or a flexible time slot (e.g., all flexible symbols that can be used for downlink or uplink).

[0097] In some aspects (e.g., when the UE 120 fails to decode the frequency-domain DCI), the UE 120 may determine that the FD time slot will use a default (e.g., pre-configured) FD frequency-domain configuration. For example, the default FD frequency-domain configuration may be configured by RRC for the UE 120. In some aspects (e.g., when the UE 120 fails to decode the frequency-domain DCI), the UE 120 may determine that the FD time slot will use the FD frequency-domain configuration indicated by a previous frequency-domain DCI received by the UE 120 (e.g., the latest frequency-domain DCI successfully decoded by the UE 120).

[0098] In some aspects, the UE 120 may send and the base station 110 may receive an indication that the decoding of the frequency-domain DCI has failed. For example, the UE 120 may send the indication in combination with one of the above techniques that can be used when the decoding of the frequency-domain DCI fails.

[0099] As indicated by reference number 720, base station 110 and UE 120 may communicate at least in part based on DCI received by UE 120. As described above, UE 120 may determine the time domain configuration for one or more time slots at least in part based on the time domain SFI indicated in the time domain DCI. In some aspects, the time domain configuration may indicate one or more FD time slots. As described above, UE 120 may determine the FD frequency domain configuration (e.g., the positions of one or more uplink frequency bands and one or more downlink frequency bands) for one or more FD time slots at least in part based on the frequency domain SFI indicated in the frequency domain DCI. In this way, DCI may be used to indicate the time domain slot format (which may indicate FD time slots) and the frequency domain slot format to be used for the FD time slots.

[0100] As noted above, Figure 7 is provided as an example. Other examples may be different from those Figure 7 described.

[0101] Figure 8 is a schematic diagram showing an example process 800 performed by a UE, for example, according to the present disclosure. Example process 800 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with DCI for frequency domain slot format indication.

[0102] As Figure 8 shown, in some aspects, process 800 may include receiving, from a base station, DCI including a plurality of frequency domain SFIs (block 810). For example, a UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive DCI including a plurality of frequency domain SFIs from a base station, as described above, for example, with reference to Figure 7 described.

[0103] As Figure 8 further shown, in some aspects, process 800 may include communicating with the base station at least in part based on the frequency domain SFI among the plurality of frequency domain SFIs (block 820).
