CROSS-REFERENCE TO RELATED APPLICATIONS

[0001]

[0001] This patent application claims priority to U.S. non-provisional patent application Ser. No. 17 / 446,570, filed Aug. 31, 2021, entitled "BANDWIDTH PART-SPECIFIC DOWNLINK-UPLINK PATTERNS," which is expressly incorporated by reference into this specification. [Technical field]

[0002] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for bandwidth part (BWP)-specific downlink (DL)-uplink (UL) patterns. [Background technology]

[0003]

[0003] Wireless communication systems have been widely deployed to provide various telecommunication services, such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, or transmit power). 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 / LTE-Advanced is an extension set of the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the 3rd Generation Partnership Project (3GPP).

[0004] A wireless network may include one or more base stations supporting communication for one user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink and uplink communications. "Downlink" (or "DL") refers to the communication link from a base station to a UE, and "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0005]

[0005] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that allows different UEs to communicate at city, national, regional, and / or global levels. New Radio (NR), sometimes referred to as 5G, is an extension set of LTE mobile standards promulgated by 3GPP. NR is designed to improve spectrum efficiency, lower costs, improve services, take advantage of new spectrum, and better support mobile broadband Internet access by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation to better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies will continue to be useful. Summary of the Invention

[0019]

[0024] Various aspects of the present disclosure are described more fully 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 disclosure to those skilled in the art. Those skilled in the art should understand that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be implemented using any number of the aspects described herein. In addition, the scope of the present disclosure is intended to cover such an apparatus or method that is implemented using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure described herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

[0020]

[0025] Certain aspects of a telecommunications system will now be presented with reference to various apparatus and techniques that will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0021]

[0026] Although aspects may be described herein generally using terminology associated with 5G or New Radio (NR) radio access technologies (RATs), aspects of the disclosure may be applicable to other RATs, such as 3G RATs, 4G RATs, and / or RATs subsequent to 5G (e.g., 6G).

[0022]

[0027] 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base stations 110 are entities that communicate with the UEs 120. The base stations 110 (sometimes referred to as BSs) may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., for 4G), gNBs (e.g., for 5G), access points, and / or transmit / receive points (TRPs). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​a base station 110 and / or a base station subsystem serving this coverage area, depending on the context in which the term is used.

[0023]

[0028] A base station 110 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 geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 with an association with a femto cell (e.g., a UE 120 in a Closed Subscriber Group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or an in-home base station. 1, BS 110a may be a macro base station for a macro cell 102a, BS 110b may be a pico base station for a pico cell 102b, and BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

[0024]

[0029] In some examples, the cells may not necessarily be fixed, and the geographic area of ​​the cells may move depending on the location of the base station 110 that is mobile (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected to each other and / or to one or more other base stations 110 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 transport network.

[0025]

[0030] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station 110 or a UE 120) and send a transmission of data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that can relay a transmission for another UE 120. In the example shown in FIG. 1, a BS 110d (e.g., a relay base station) may communicate with a BS 110a (e.g., a macro base station) and a UE 120d to facilitate communication between the BS 110a (e.g., a macro base station) and the UE 120d. A base station 110 that relays communication may be referred to as a relay station, a relay base station, a repeater, or the like.

[0026]

[0031] The wireless network 100 may be a heterogeneous network including different types of base stations 110, such as, for example, macro base stations, pico base stations, femto base stations, or relay base stations. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different susceptibility to interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5-40 watts), whereas a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1-2 watts).

[0027]

[0032] A network controller 130 may couple to or communicate with a set of base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may communicate with each other directly or indirectly via wireless or wireline backhaul communication links.

[0028]

[0033] The UEs 120 may be distributed throughout the wireless network 100, and each UE 120 may be fixed or mobile. The UEs 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. The UEs 120 may be a cellular phone (e.g., a smartphone), 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, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, a smart clothing, a smart glasses, a smart wristband, a smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate over a wireless medium.

[0029]

[0034] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and / or a location tag that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. The UE 120 may be included inside a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0030]

[0035] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. The RAT may be referred to as a radio technology, an air interface, or the like. The frequencies may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0031]

[0036] In some examples, 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 the base station 110 as an intermediary to communicate with each other). For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) protocols (which may include, e.g., vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, the UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0032]

[0037] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, or channels, etc. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers, although portions of FR1 are greater than 6 GHz. A similar nomenclature issue sometimes arises with respect to FR2, which is often referred to (interchangeably) as the "millimeter wave" band in documents and papers, even though FR2 is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" band.

[0033]

[0038] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified these mid-band frequency operating bands as frequency range designation FR3 (7.125 GHz to 24.25 GHz). Frequency bands that fall within FR3 may inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being investigated to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0034]

[0039] With the above examples in mind, it should be understood that unless otherwise specified, terms such as "sub-6 GHz" as used herein may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, unless otherwise specified, it should be understood that terms such as "millimeter wave" as used herein may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0035]

[0040] In some aspects, the UE 120 may include a communications manager 140. As described in more detail elsewhere herein, the communications manager 140 may receive from a base station a configuration of a plurality of bandwidth portions (BWPs) in a frequency band, where the configuration specifies a respective BWP-specific downlink (DL)-uplink (UL) pattern for each BWP of the plurality of BWPs, where at least two BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns, where each DL-UL pattern specifies which time intervals of the plurality of time intervals are dedicated to the downlink and which time intervals of the plurality of time intervals are dedicated to the uplink, and may communicate with the base station in one or more active BWPs of the plurality of BWPs using the respective BWP-specific DL-UL pattern for each of the one or more active BWPs of the plurality of BWPs. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0036]

[0041] In some aspects, the base station 110 may include a communications manager 150. As described in more detail elsewhere herein, the communications manager 150 may transmit to the UE a configuration of a plurality of BWPs in a frequency band, where the configuration specifies a respective BWP-specific DL-UL pattern for each BWP of the plurality of BWPs, where at least two BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns, where each DL-UL pattern specifies which time intervals of the plurality of time intervals are dedicated to the downlink and which time intervals of the plurality of time intervals are dedicated to the uplink, and may communicate with the UE in one or more active BWPs of the plurality of BWPs using the respective BWP-specific DL-UL pattern for each of the one or more active BWPs of the plurality of BWPs. Additionally or alternatively, the communications manager 150 may perform one or more other operations described herein.

[0037]

[0042] As noted above, Figure 1 is provided as an example. Other examples may differ from those described with respect to Figure 1.

[0038]

[0043] 2 is a diagram illustrating an example base station 110 200 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with a set of antennas 234a-t, such as T antennas, where T≧1. The UE 120 may be equipped with a set of antennas 252a-r, such as R antennas, where R≧1.

[0039]

[0044] At the base station 110, a transmit processor 220 may receive data directed to a UE 120 (or set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from that UE 120. The base station 110 may process (e.g., encode and modulate) data for the UE 120 based at least in part on the MCS(es) selected for the UE 120 and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or higher layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for a reference signal (e.g., a cell-specific reference signal (CRS) or demodulation reference signal (DMRS)) and a synchronization signal (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A 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 a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), depicted as modems 232a through 232t. For example, each output symbol stream may be provided to a modulator component (depicted as MOD) of modem 232. Each modem 232 may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 may further process (eg, convert to analog, amplify, filter, and / or upconvert) the output sample stream using a respective modulator component to obtain a downlink signal.Modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) illustrated as antennas 234a through 234t.

[0045] At the UE 120, a set of antennas 252 (depicted as antennas 252a through 252r) may receive downlink signals from the base station 110 and / or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) depicted as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (depicted as DEMOD) of the modems 254. Each modem 254 may condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal using a respective demodulator component to obtain input samples. Each modem 254 may further process the input samples (e.g., for OFDM) using the demodulator component to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, perform MIMO detection on the received symbols, if applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control 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 CQI parameters, among other examples. In some examples, one or more components of the UE 120 may be included within the housing 284.

[0041]

[0046] 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.

[0042]

[0047] One or more antennas (e.g., antennas 234a-t and / or antennas 252a-r) may include or be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more 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 (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components of FIG.

[0043]

[0048] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (eg, with reference to FIGS. 4-8).

[0044]

[0049] At the base station 110, uplink signals from the UE 120 and / or other UEs may be received by an antenna 234, processed by a modem 232 (e.g., a demodulator component shown as DEMOD of the modem 232), detected by a MIMO detector 236, if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 for scheduling one or more UEs 120 for downlink and / or uplink communication. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modem(s) 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 memory 242 to perform any aspects of the methods described herein (e.g., with reference to FIGS. 4-8).

[0045]

[0050] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component(s) of FIG. 2 may perform one or more techniques related to BWP-specific DL-UL patterns as described in detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component(s) of FIG. 2 may perform or direct operations of, for example, process 500 of FIG. 5, process 600 of FIG. 6, and / or other processes described herein. The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some examples, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and / or the UE 120 (e.g., directly or after compilation, translation, and / or interpretation), may cause the one or more processors, the UE 120, and / or the base station 110 to perform or direct operations, such as, for example, of process 500 of FIG. 5, process 600 of FIG. 6, and / or other processes described herein. In some examples, executing the instructions may include executing the instructions, translating the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.

[0046]

[0051] In some aspects, the UE 120 includes means for receiving from a base station (e.g., using the antennas 252, the modem 254, the MIMO detector 256, the receive processor 258, the controller / processor 280, or the memory 282, etc.) a configuration of a plurality of BWPs in a frequency band, where the configuration identifies a respective BWP-specific DL-UL pattern for each BWP of the plurality of BWPs, where at least two BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns, where each DL-UL pattern specifies which time intervals of the plurality of time intervals are dedicated to the downlink and which time intervals of the plurality of time intervals are dedicated to the uplink, and / or means for communicating with the base station in one or more active BWPs using the respective BWP-specific DL-UL pattern for each of one or more active BWPs of the plurality of BWPs (e.g., using the antennas 252, the modem 254, the MIMO detector 256, the receive processor 258, the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, or the memory 282, etc.). The means for the UE 120 to perform the operations described herein may include, for example, one or more of the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0047]

[0052] In some aspects, base station 110 includes means for transmitting to the UE (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, modem 232, antennas 234, or memory 242, etc.) a configuration of a plurality of BWPs in a frequency band, where the configuration specifies a respective BWP-specific DL-UL pattern for each BWP of the plurality of BWPs, at least two BWPs of the plurality of BWPs are configured with different BWP-specific DL-UL patterns, each DL-UL pattern specifying which time intervals of the plurality of time intervals are dedicated to downlink and which time intervals of the plurality of time intervals are dedicated to uplink, and / or means for communicating with the UE in one or more active BWPs using a respective BWP-specific DL-UL pattern for each of one or more active BWPs of the plurality of BWPs (e.g., using controller / processor 240, transmit processor 220, TX MIMO processor 230, modem 232, antennas 234, MIMO detector 236, receive processor 238, or memory 242, etc.). The means for the base station 110 to perform the operations described herein may include, for example, one or more of the communications manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antennas 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0048]

[0053] 2 are illustrated as separate components, the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combination component, or in various combinations of components. For example, functionality described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0049]

[0054] As noted above, Figure 2 is provided as an example. Other examples may differ from those described with respect to Figure 2.

[0050]

[0055] FIG. 3 illustrates examples 300, 305, and 310 of full-duplex communication in a wireless network according to the present disclosure. "Full-duplex communication" in a wireless network refers to simultaneous bidirectional communication between devices in the wireless network. For example, a UE operating in full-duplex mode may transmit uplink communication and receive downlink communication at the same time (e.g., in the same slot). "Half-duplex communication" in a wireless network refers to unidirectional communication (e.g., downlink or uplink communication) between devices at a given time (e.g., in a given slot). Currently, in NR, frequency bands are often referred to as frequency division duplex (FDD) bands or time division duplex (TDD) bands based on the definition in the wireless standard, but this distinction may be less useful in the context of full-duplex communication, where within a given band (whether currently defined as an FDD band or a TDD band in NR), both uplink (UL) and downlink (DL) communication may occur simultaneously within various sub-bands within the band.

[0051]

[0056] As shown in FIG. 3, examples 300 and 305 illustrate examples of in-band full-duplex (IBFD) communication. In IBFD, a UE may transmit uplink communication to a base station and receive downlink communication from a base station on the same time and frequency resources. As shown in example 300, in IBFD, the time and frequency resources for uplink communication may fully overlap with the time and frequency resources for downlink communication. Thus, as illustrated in example 300, in the box labeled UL, both uplink and downlink communication may occur simultaneously. As shown in example 305, in IBFD, the time and frequency resources for uplink communication may partially overlap with the time and frequency resources for downlink communication.

[0052]

[0057] As further shown in FIG. 3, example 310 illustrates an example of sub-band full-duplex (SBFD) communication, sometimes referred to as “flexible duplex.” In SBFD, a UE may transmit uplink communications to a base station and receive downlink communications from the base station simultaneously, but on different frequency resources (within the same band). For example, the different frequency resources may be sub-bands of a frequency band, such as a time division duplex TDD band (i.e., a frequency band currently defined as a TDD band in NR) or a frequency division duplex FDD band (i.e., a frequency band currently defined as a TDD band in NR). In this case, the downlink resources may be separated in the frequency domain from the uplink resources by a guard band.

[0053]

[0058] As noted above, Figure 3 is provided as an example. Other examples may differ from those described with respect to Figure 3.

[0054]

[0059] In some examples, multiple BWPs may be configured for a UE in one frequency band or component carrier (CC). For example, a UE may be configured with multiple downlink BWPs (e.g., up to four) and / or multiple uplink BWPs (e.g., up to four). In this case, one BWP may be activated at a time. For example, one configured downlink BWP may be activated for downlink communication, and one configured uplink BWP may be activated for uplink communication. In some examples, a downlink (DL)-uplink (DL) pattern may also be configured for a UE. A DL-UL pattern is, for example, a pattern of slot formats (e.g., downlink slots, uplink slots, or flexible slots) for some slots, while a DL-UL pattern may be defined over any time interval (symbol, transmission time interval (TTI), subslot, slot, etc.). A DL-UL pattern may be applied to all configured BWPs in a frequency band or CC. For example, one active downlink BWP may be used for one downlink slot and one active uplink BWP may be used for one uplink slot. In some examples, to enable full-duplex operation, one or more slots may be configured to be full-duplex slots, where the configured frequency resource allocation for full-duplex communication is used for full-duplex communication. Full-duplex communication may provide the benefit of increased bandwidth for communication between the base station and the UE by allowing the base station and the UE to transmit and receive on the same set of resources. However, using the configured full-duplex slots and the configured frequency resource allocation for all instances of full-duplex communication may not be flexible and may not be optimal for scheduling full-duplex downlink and communication.

[0055]

[0060] Some techniques and apparatuses described herein enable a BWP-specific DL-UL pattern to be configured for a UE. In some aspects, a UE may receive a configuration of multiple BWPs in a frequency band from a base station, and the configuration may specify a respective BWP-specific DL-UL pattern for each BWP of the multiple BWPs. The UE and the base station may communicate in one or more active BWPs using a respective BWP-specific DL-UL pattern for each of the one or more active BWPs. In some aspects, multiple BWPs may be activated simultaneously and used together to enable full-duplex operation in one or more slots, and different combinations of BWPs may be activated or deactivated to achieve different configurations for full-duplex operation with low signaling overhead. As a result, the flexibility of allocating resources for full-duplex communication may be increased, which may increase network speeds for full-duplex communication and reduce traffic latency.

[0056]

[0061] 4 is a DL-UL pattern according to the present disclosure. As shown in FIG. 4, an example 400 includes communication between a base station 110 and a UE 120. In some aspects, the base station 110 and the UE 120 may be included in a wireless network, such as the wireless network 100. The base station 110 and the UE 120 may communicate via a wireless access link, which may include an uplink and a downlink.

[0057]

[0062] As indicated by reference numeral 405 in FIG. 4, the base station 110 may transmit to the UE 120 a configuration of multiple BWPs in a frequency band or CC. A BWP is a configured contiguous set of frequency resources of a carrier for communication by a UE that may be activated or deactivated by signaling such as a DCI message. For example, the base station 110 may transmit the configuration to the UE 120 in a radio resource control (RRC) message. The UE 120 may receive the configuration from the base station 110. The configuration may specify a respective BWP-specific DL-UL pattern for each BWP in the multiple BWPs. In some aspects, at least two of the BWPs in the same frequency band or CC may be configured with different BWP-specific DL-UL patterns. In some aspects, at least two of the BWPs configured with their respective BWP-specific DL-UL patterns may fully or partially overlap. In some aspects, at least two of the BWPs configured with their respective BWP-specific DL-UL patterns may be adjacent. In some aspects, at least two of the BWPs configured with their respective BWP-specific DL-UL patterns may be separated by a guard band.

[0058]

[0063] A BWP-specific DL-UL pattern for a BWP is a pattern of time interval formats for multiple time intervals (e.g., symbols, transmission time intervals (TTIs), subslots, slots, etc.). For ease of explanation, examples described below are described with reference to time intervals equal to slots. For a given slot in a BWP-specific DL-UL pattern, the slot format may be downlink (e.g., downlink slot), uplink (e.g., uplink slot), or flexible (e.g., flexible slot). A flexible slot is a slot that may be used as a downlink slot or an uplink slot (e.g., based at least in part on a slot format indicator (SFI) transmitted from the base station 110 to the UE 120). As shown in FIG. 4, the configuration may specify a first DL-UL pattern for a first BWP (BWP1) and a second DL-UL pattern for a second BWP (BWP2). For example, as shown in FIG. 4, the first DL-UL pattern (for BWP1) may be DDDU (e.g., three downlink slots followed by one uplink slot), and the second DL-UL pattern (for BWP2) may be DUUU (e.g., one downlink slot followed by three uplink slots). As illustrated, the first DL-UL pattern is different from the second DL-UL pattern because slots 2 and 3 are illustrated as being different. However, more generally, the first DL-UL pattern is considered to be different from the second DL-UL pattern as long as there is at least one slot in which the first pattern specifies a different slot format than the second pattern. In some aspects, one or more of the BWP-specific DL-UL patterns may also include one or more flexible slots.

[0059]

[0064] In some aspects, the configuration may include a common slot format indication that applies to all of the BWPs and a respective dedicated slot format indication for each of the BWPs. For example, the common slot format indication may indicate a slot format for one or more slots in each BWP-specific DL-UL pattern that is the same for all of the BWP-specific DL-UL patterns (e.g., for all of the BWPs). In some aspects, the common slot format indication may indicate that each BWP-specific DL-UL pattern begins with one or more downlink slots and ends with one or more uplink slots. The respective dedicated slot format indication for a BWP may indicate a slot format (e.g., downlink, uplink, or flexible) for the remaining slots in the BWP-specific DL-UL pattern that are not configured by the common slot format indication.

[0060]

[0065] In some aspects, the configuration may configure one or more of the BWPs to be active BWPs. In some aspects, the configuration may configure multiple BWPs to be active BWPs simultaneously. In some aspects, by indicating multiple active BWPs in the configuration (or in a downlink control information (DCI)-based dynamic indication), the base station 110 may enable / activate full-duplex operation in one or more slots and / or half-duplex operation in one or more slots based at least in part on the BWP-specific DL-UL pattern of each of the multiple active BWPs. For example, the active BWPs may include a first active BWP configured with a first BWP-specific DL-UL pattern and a second active BWP configured with a second BWP-specific DL-UL pattern. In this case, the UE 120 and the base station 110 may operate in half-duplex (HD) mode in slots having the same slot format in the first BWP-specific DL-UL pattern and the second BWP-specific DL-UL pattern, and the UE 120 and the base station 110 may operate in full-duplex (FD) mode in slots having different slot formats in the first BWP-specific DL-UL pattern and the second BWP-specific DL-UL pattern. In some aspects, in slots in which the UE 120 and the base station 110 operate in full-duplex mode, overlapping active BWPs may be used to enable IBFD communication (e.g., IBFD mode). In some aspects, in slots in which the UE 120 and the base station 110 operate in full-duplex mode, adjacent BWPs or BWPs separated by guard bands may be used to enable SBFD communication (e.g., SBFD mode).

[0061]

[0066] In some aspects, multiple BWPs configured with respective BWP-specific DL-UL patterns may be multiple "flexible" BWPs, where the configuration may also specify one or more configured downlink BWPs and / or one or more configured uplink BWPs, where a flexible BWP is a BWP that may be used for downlink and / or uplink communications based at least in part on the respective BWP-specific DL-UL pattern.

[0062]

[0067] 4, the base station 110 may transmit a DCI including a BWP activation and / or an SFI to the UE 120. The UE 120 may receive and decode the DCI transmitted from the base station 110.

[0063]

[0068] In some aspects, the DCI may include an indication of one or more configured BWPs with respective BWP-specific DL-UL patterns to be activated as active BWPs. For example, the DCI may include dynamic indications to activate one or more BWPs, deactivate one or more BWPs, and / or switch one or more active BWPs from one or more currently active BWPs to one or more indicated active BWPs. In some aspects, the DCI may include dynamic indications of multiple BWPs to be activated. In this case, the multiple active BWPs may be used to enable / activate full-duplex operation in one or more slots and / or half-duplex operation in one or more slots based at least in part on the respective BWP-specific DL-UL patterns of the multiple active BWPs.

[0064]

[0069] In some aspects, the DCI may include an SFI. The SFI may indicate an uplink or downlink slot format for one or more flexible slots for at least one BWP having a BWP-specific DL-UL pattern including one or more flexible slots. In some aspects, the DCI including the SFI may be DCI format 2_0 (DCI 2_0) defined or otherwise determined by a wireless communication specification, such as one published by 3GPP. In some aspects, the DCI may further include an indication of which BWPs of the configured BWPs the UE 120 should apply the SFI to. In some aspects, the DCI (e.g., DCI 2_0) may include a bit field to indicate the BWPs to which the SFI should be applied. For example, if the UE 120 is configured with four BWPs, the DCI may include two bits in the DCI field to indicate the BWPs to which the SFI should be applied. In some aspects, the DCI may be a group-common DCI, and the position of the SFI in the bit field of the DCI may indicate at least one BWP to which the SFI should be applied. For example, UE 120 may be configured with a set of positions in a bit field of a DCI (e.g., DCI 2_0) (e.g., in an RRC configuration received from base station 110), and each position in the bit field of the DCI configured for UE 120 may be associated with a respective BWP configured for UE 120. In this case, UE 120 may decode the DCI (e.g., DCI 2_0) and scan the SFIs in the positions in the bit field of the DCI configured for UE 120 to determine the SFI for each configured BWP for UE 120. In some aspects, a position in the bit field of the DCI configured for UE 120 may be associated with more than one BWP configured for UE 120. In this case, the multiple BWPs associated with a position in the bit field may have the same slot format (e.g., the SFI in a position in the bit field of the DCI may apply to each of the multiple BWPs associated with the position).

[0065]

[0070] As further indicated by reference numeral 415 in FIG. 4, the UE 120 and the base station 110 may communicate in an active BWP using a respective BWP-specific DL-UL pattern associated with each active BWP. In some aspects, the UE 120 and the base station 110 may communicate using multiple active BWPs simultaneously. For example, an active BWP may include a first active BWP configured with a first BWP-specific DL-UL pattern and a second active BWP configured with a second BWP-specific DL-UL pattern. In this case, the UE 120 and the base station 110 may communicate in half-duplex mode in slots having the same slot format in the first BWP-specific DL-UL pattern and the second BWP-specific DL-UL pattern, and the UE 120 and the base station 110 may communicate in full-duplex mode in slots having different slot formats in the first BWP-specific DL-UL pattern and the second BWP-specific DL-UL pattern. For example, if BWP1 and BWP2 shown in FIG. 4 are active BWPs, UE 120 may receive downlink communications from base station 110 on BWP1 and BWP2 in the first slot (e.g., half-duplex mode operation), UE 120 may receive downlink communications from base station 110 on BWP1 and transmit uplink communications to UE 120 on BWP2 in the second and third slots (e.g., full-duplex mode operation), and UE 120 may transmit uplink communications on BWP1 and BWP2 in the fourth slot (e.g., half-duplex mode operation).

[0066]

[0071] Although the illustration of FIG. 4 shows non-overlapping BWPs for operation in SBFD mode, it should be understood that in some aspects, if a first active BWP overlaps with a second active BWP, the UE 120 and the base station 110 may communicate in IBFD mode in slots having different slot formats in the first BWP-specific DL-UL pattern and the second BWP-specific DL-UL pattern. In some aspects, if a first active BWP is adjacent to a second active BWP or is separated from a second active BWP by a guard band, the UE 120 and the base station 110 may communicate in SBFD mode in slots having different slot formats in the first BWP-specific DL-UL pattern and the second BWP-specific DL-UL pattern. The IBFD mode may use different transmission or reception parameters (e.g., power control, etc.) than the SBFD mode. The FD mode (e.g., IBFD mode or SBFD mode) may use different transmission or reception parameters than the HD mode.

[0067]

[0072] In some aspects, in slots where active BWPs operate in the same direction (e.g., slots having the same slot format in a first BWP-specific DL-UL pattern and a second BWP-specific DL-UL pattern), the UE 120 and the base station 110 may communicate in a half-duplex mode (e.g., downlink or uplink) in a combined BWP including the first BWP and the second BWP. For example, the UE 120 and the base station 110 may communicate in a combined BWP in slots having the same slot format in a first BWP-specific DL-UL pattern and a second BWP-specific DL-UL pattern if the first active BWP and the second active BWP are adjacent, partially overlapping, and / or separated by a guard band.

[0068]

[0073] In some aspects, if the first and second active BWPs are separated by a guard band, the combined BWP may include the first active BWP, the second active BWP, and the guard band. For example, as shown in FIG. 4 by reference numeral 420, if the active BWPs (BWP1 and BWP2) are separated by a guard band (GB), the UE 120 may receive downlink communication from the base station 110 in a first slot (e.g., in half-duplex mode) in a combined BWP that includes BWP1, BWP2, and the guard band, and the UE 120 may transmit uplink communication to the base station 110 in a fourth slot (e.g., in half-duplex mode) in a combined BWP that includes BWP1, BWP2, and the guard band. In some aspects, using the combined BWP (including the guard band) for active BWPs separated by a guard band may be based at least in part on a determination of whether a size (e.g., in terms of resource blocks (RBs)) of the guard band between the active BWPs meets a threshold. In this case, the threshold may be configured for UE 120 in an RRC configuration received from base station 110 (eg, a BWP configuration or another RRC configuration).

[0069]

[0074] In some aspects, UE 120 may apply a configuration (e.g., a physical downlink shared channel (PDSCH) configuration, or a physical uplink shared channel (PUSCH) configuration, etc.) of the combined BWP that is the same as a configuration of one or more active BWPs included in the combined BWP (e.g., other than the center frequency and the starting and ending RBs). For example, which of the active BWPs to use to set the configuration for the combined BWP may be configured for UE 120 (e.g., in the RRC configuration of the BWP).

[0070]

[0075] As described above, the UE 120 may receive from the base station 110 a configuration of multiple BWPs in a frequency band, and the configuration may specify a respective BWP-specific DL-UL pattern for each BWP of the multiple BWPs. The UE 120 and the base station 110 may communicate in one or more active BWPs using the respective BWP-specific DL-UL pattern for each of the one or more active BWPs. In some aspects, multiple BWPs may be activated simultaneously and used together to enable full-duplex operation in one or more slots, and different combinations of BWPs may be activated or deactivated to achieve different configurations for full-duplex operation with low signaling overhead.
