[0002] This patent application claims priority to PCT patent application filed on April 9, 2020, entitled "FLEXIBLE TIME DIVISION DUPLEXING CONFIGURATION" and numbered PCT / CN2020 / 083860, which has been assigned to the assignee of this application. The disclosure of the earlier application is considered part of this patent application and is incorporated herein by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communications, and to technologies and apparatuses for flexible time-division duplex (TDD) configurations. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users 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 / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with the BS via downlink and 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, the BS may be referred to as Node B, gNB, Access Point (AP), Radio Headend, Transmit / Receive Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. NR (which can also be called 5G) is an enhancement set of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other wireless access technologies remain useful. Summary of the Invention

[0032] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of the disclosure herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or method may be implemented using any number of the aspects set forth herein.

It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0033] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings, by way of various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively, “elements”). These elements may be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0034] It should be noted that although the aspects may be described herein using terms commonly associated with 5G or NR radio access technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0035] Figure 1 This is a schematic diagram illustrating an example of a wireless network 100 according to this disclosure. Wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, as well as other examples. 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 can provide communication coverage for a specific geographic 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.

[0036] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be called a macro BS. A BS used for picocells can be called a pico BS. A BS used for femtocells can be called a femto BS or a home BS. Figure 1 In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0037] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may be movable depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0038] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, repeater, etc.

[0039] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (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 effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (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).

[0040] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0041] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, or satellite radio unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0042] Some UEs can be considered 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 capable of communicating with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing housing the components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific Radio Access Platform (RAT) and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0044] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary for communication). For example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.) and / or mesh networks. In this case, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described herein as being performed by base station 110.

[0045] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) (which can span from 410 MHz to 7.125 GHz), and / or can communicate using an operating band with a second frequency range (FR2) (which 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 "below 6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although this is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise expressly stated, it should be understood that the terms "below 6 GHz" and the like (if used herein) can broadly refer to frequencies below 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., above 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the terms "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., below 24.25 GHz). It is anticipated that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0046] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0047] Figure 2 This is a schematic diagram illustrating an example of communication between base station 110 and UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a to 234t, and UE 120 may be equipped with R antennas 252a to 252r, wherein typically T ≥ 1 and R ≥ 1.

[0048] At base station 110, transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQI) received from each UE, process (e.g., code and modulate) the data for each UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. Transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, permission, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM) process its respective output symbol stream to obtain an output sample stream. Each modulator 232 can 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 to 232t can be transmitted via T antennas 234a to 234t respectively.

[0049] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Signal Received Power (RSRP) parameter, Received Signal Strength Indicator (RSSI) parameter, Reference Signal Received Quality (RSRQ) parameter, and / or CQI parameter, as well as other examples. In some aspects, one or more components of the UE 120 may be included within the housing 284.

[0050] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in the core network. Network controller 130 may communicate with base station 110 via communication unit 294.

Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as...) Figure 2 One or more antenna elements (one or more components).

[0052] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting RSRP, RSSI, RSRQ, and / or CQI). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-coded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of UE 120 can be included in the modem of UE 120. In some aspects, UE 120 includes a transceiver. The transceiver may include any combination of 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 memory 282 to perform aspects of any of the methods described herein, such as those referenced. Figures 3-7 Described.

[0053] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide decoded data to data sink 239 and decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and transmission to network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, modulators and demodulators (e.g., MOD / DEMOD 232) of base station 110 may be included in the modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, such as those referenced.

For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, translation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example...

[0057] In some aspects, the BS includes units for transmitting information elements identifying a time slot format pattern for use during time division duplexing, wherein the length of a parameter of the information element, or the length indicated by a parameter of the information element, satisfies a threshold at least in part based on the period of the time slot format pattern; or units for communicating with the UE in TDD mode according to the time slot format pattern.

[0058] In some aspects, the BS includes units for receiving information elements identifying a time slot format pattern for use during time division duplexing, wherein the length of a parameter of the information element, or the length indicated by a parameter of the information element, satisfies a threshold at least in part based on the period of the time slot format pattern; or units for communicating with the UE or the BS in TDD mode according to the time slot format pattern.

[0059] Although Figure 2 The boxes in the diagram are shown as distinct components, but the functions described above with respect to the boxes can 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 can be performed by the controller / processor 280 or under the control of the controller / processor 280.

[0060] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0061] In some communication systems, multiple different TDD uplink (UL) downlink (DL) (UL-DL) configurations can be possible. Each TDD UL-DL configuration can have an associated set of time slot formats for multiple symbols during a communication cycle. For example, as shown in Table 11.1.1-1 of the 3GPP Technical Specification (TS) 38.213 for time slot formats for a common cyclic prefix, symbols can be assigned as downlink symbols (D), uplink symbols (U), flexible symbols (F), etc. In this case, the time slot format table includes a full downlink symbol format (Format 0), a full uplink symbol format (Format 1), and a full flexible symbol format (Format 2). Formats 3 through 55 include at least one flexible symbol and different combinations of one or more uplink symbols and / or downlink symbols.

[0062] During communication configuration, the BS can send information elements (IEs) such as "Intended TDD DL-UL Configuration NR" to establish the time slot format for communication. The defined information elements can support enumeration of time slot formats 0 through 45 from the aforementioned time slot format table. However, the defined information elements do not support indications for time slot formats 46 through 55. For example, time slot formats 46 through 53 and 55 include multiple DL-UL direction switches, which may result in the information elements including insufficient bits to indicate the time slot format. Furthermore, time slot format 54 neither begins nor ends with a downlink symbol (time slot format 54 begins with a flexible symbol and ends with a downlink symbol), which may require a larger number of bits than are available in the defined information elements for identification. Additionally, other possible time slot formats can be defined for the communication system, which may not be recognizable using the defined information elements. By limiting the set of time slot formats that can be configured for a communication system, the flexibility to adapt to network service conditions is restricted, thereby reducing network efficiency and performance.

[0063] Some aspects described herein prepare for flexible TDD configuration. For example, the BS can send information elements including time slot format configuration information for full-time slot or half-time slot types. In this case, the UE can interpret the information elements to identify the full-time slot or half-time slot type, and can identify the time slot format at least in part based on whether the information element identifies the full-time slot or half-time slot type. In this case, at least in part based on enabling the information elements to convey information for half-time slots rather than full-time slots, the BS and UE enable the information elements to identify each time slot format in the aforementioned time slot format table, as well as other possible time slot formats, to provide additional flexibility to network communication. Furthermore, although some aspects are described in the context of communication between the BS and the UE, the BS can provide information elements to another BS, to nodes in a hierarchical network, etc., thereby providing flexibility for TDD configuration in other types of deployments.

[0064] Figure 3 This is a schematic diagram illustrating example 300 of a flexible TDD configuration according to various aspects of this disclosure. Figure 3 As shown, Example 300 includes BS 110 and UE 120.

[0065] As in Figure 3 As further shown by reference numeral 310 in the accompanying drawings, BS 110 can send information elements to UE 120. For example, BS 110 can determine the time slot format that UE 120 will use for communication, and can send information elements to convey information identifying the time slot format. In some aspects, BS 110 can send information elements to UE 120 to identify the time slot format. For example, when BS 110 and UE 120 are in direct communication, BS 110 can send information elements to UE 120 so that UE 120 can determine the time slot format. Alternatively or additionally, BS 110 can send information elements to another BS 110, a sub-node (e.g., in an Integrated Access and Backhaul (IAB) deployment), etc. For example, BS 110 can send information elements on an Xn Application Protocol (AP) interface, an F1-AP interface, etc. Alternatively or additionally, BS 110 can use Radio Resource Control (RRC) signaling, System Information Block (SIB) signaling, etc., to send information elements.

[0066] In some aspects, the BS 110 can be associated with multiple cells, multiple distributed units (DUs) each having one or more cells, etc. For example, the BS 110 can be a central unit (CU) with multiple DUs, and each DU can have multiple cells. In this case, the BS 110 can indicate the TDD UL-DL configuration at the node level (e.g., DU level or cell level) by including information identifying the time slot format (e.g., information elements) in the configuration message. For example, the BS 110 can provide the information identifying the time slot format in Xn-AP configuration update messages, Xn-AP configuration update confirmation messages, Xn establishment request messages, Xn establishment response messages, etc. Alternatively or additionally, the BS 110 can provide the information identifying the time slot format in F1-AP CU configuration update messages, F1-AP DU configuration update information, etc. In some aspects, the BS 110 can identify the time slot format used on a specific frequency carrier.

[0067] In some aspects, BS 110 may transmit information elements with a specific timeslot type for identifying timeslot formats. For example, BS 110 may transmit information elements with a half-timeslot timeslot type, which allows BS 110 to identify multiple different timeslot formats, such as each timeslot format in the timeslot format table described above. Alternatively, BS 110 may transmit information elements with a full-timeslot timeslot type, which enables the identification of subsets of timeslot formats from multiple different timeslot formats. Alternatively, BS 110 may transmit information elements with a full-timeslot timeslot type to provide backward compatibility with some UEs 120 that are not configured in the information elements to use information elements with a half-timeslot timeslot type.

[0068] As in Figure 3As further shown by reference numeral 320 in the accompanying drawings, UE 120 can determine the time slot format at least in part based on information elements. For example, UE 120 can decode information elements to identify the time slot format identified by the information elements. In some aspects, UE 120 can determine whether the information element includes a full-time slot type or a half-time slot type. For example, UE 120 can determine whether the information element includes a full-time slot type or a half-time slot type based at least in part on the subcarrier spacing (SCS), transmission period, length of the time slot configuration list, or length indicated by the time slot configuration list. In this case, UE 120 can determine whether the (SCS / 15 kHz)*NR DL-UL transmission period parameter is equal to the length of the time slot configuration list (information element includes full-time slot type) or less than the length of the time slot configuration list (information element includes half-time slot type). In this case, based at least in part on whether the information element includes a full-slot time slot type or a half-slot time slot type, UE 120 can determine which time slot format UE 120 will use to communicate with BS 110.

[0069] In some aspects, the length of the time slot configuration list that identifies the time slot format style, or the length indicated by the time slot configuration list, can be extended to support additional TDD UL-DL transmission cycles. For example, the BS 110 can send information elements with an extended time slot configuration list to support transmission cycles between 10 milliseconds (ms) and 160 ms. In this case, the maximum number of time slots can be extended from a maximum of 320 for a 10 ms cycle to 5120. This can improve network performance relative to other maximum lengths of the time slot configuration list. For example, in some communication systems, the maximumnoofslots parameter can be set to 320, which supports full flexibility for a 10 ms UL-DL transmission cycle. However, by setting the maximumnoofslots parameter to 5120, full flexibility for a 160 ms UL-DL transmission cycle can be achieved.

[0070] As in Figure 3 As further shown by reference numeral 330 in the accompanying drawings, UE 120 can communicate with BS 110 according to the identified time slot format. For example, UE 120 can transmit on the uplink during an uplink symbol or flexible symbol, and receive on the downlink during a downlink symbol or flexible symbol, etc.

[0071] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0073] like Figure 4 As shown, in some aspects, process 400 may include selecting a timeslot format for use during time-division duplexing from a plurality of timeslot formats for supporting time-division duplexing (box 410).

For example, a UE (e.g., using a receive processor 258, a transmit processor 264, a controller / processor 280, a memory 282, etc.) may receive an information element that includes a half-slot time slot type or a full-slot time slot type for identifying a time slot format used during time division duplexing among a plurality of time slot formats for supporting time division duplexing, as described above.
