Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Patent Application No. 17 / 821,234, filed on August 22, 2022, entitled “INDICATING SUB-BAND LOCATIONS FOR SUB-BAND FULL DUPLEX COMMUNICATION” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of and incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for indicating sub-band locations for sub-band full-duplex communications. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region, and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink, 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 to better integrate with other open standards; and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the invention

[0028] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functionality, or structure and functionality in addition to or different from the various aspects of the 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 the claims.

[0029] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0030] In some aspects, the term "receive" and its variations (e.g., "received" and / or "received", etc.) may alternatively be referred to as "obtain" or its respective variations (e.g., "obtained" and / or "obtained", etc.). Similarly, the term "send" and its variations (e.g., "send" and / or "sent", etc.) may alternatively be referred to as "provide" or its corresponding variations (e.g., "provide" and / or "provided", etc.), "generate" or its corresponding variations (e.g., "generate" and / or "generated", etc.), and / or "output" or its corresponding variations (e.g., "output" and / or "outputted", etc.).

[0031] Although various aspects may be described herein using terminology generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or 5G and beyond (e.g., 6G) RATs.

[0032] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0033] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0034] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of ​​the network node 110 and / or a network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 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 a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 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 a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. The network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0035] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0036] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0037] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0038] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0039] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may 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 computer, 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, smart clothing, smart glasses, a smart wristband, 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, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0040] 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, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, 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. UE 120 may be included inside a housing that houses components of 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, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0041] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. 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.

[0042] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 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, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0043] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. 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-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, 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).

[0044] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). The frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, and thus may effectively extend the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band.

[0045] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term 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.

[0046] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, communication manager 140 may receive an indication of whether a rate matching pattern indicates an uplink subband for sub-band full-duplex communication and a location of at least one guard band, the rate matching pattern identifying resources to be avoided for downlink data communication; and communicate according to the rate matching pattern based at least in part on the indication. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

[0047] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send an indication of whether a rate matching pattern indicates an uplink subband for sub-band full-duplex communication and a location of at least one guard band, the rate matching pattern identifying resources to be avoided for downlink data communication; and communicate according to the rate matching pattern based at least in part on the indication. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0048] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0049] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0050] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may 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 signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where 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) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0051] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide 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 a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0052] 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 network node 110 via the communication unit 294.

[0053] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0054] 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 generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, reference Figures 5 to 9 ) any aspects of any of the methods described herein.

[0055] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain 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 provide the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 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 operations described herein (e.g., with reference to Figures 5 to 9 ) any aspects of any of the methods described herein.

[0056] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 6 The process of 600 Figure 7 10 and / or other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing 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 network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The process 700 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0057] In some aspects, the UE 120 includes means for receiving an indication of whether a rate matching pattern indicates an uplink subband for sub-band full-duplex communication and a location of at least one guard band, the rate matching pattern identifying resources to be avoided for downlink data communication (e.g., using the antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.); and / or means for communicating in accordance with the rate matching pattern based at least in part on the indication (e.g., using the antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.). Means for the UE 120 to perform operations described herein may include, for example, one or more of the communication 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.

[0058] In some aspects, the network node 110 includes means for transmitting an indication of whether a rate matching pattern indicates an uplink subband for sub-band full-duplex communication and a location of at least one guard band, the rate matching pattern identifying resources to be avoided for downlink data communication (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the memory 242, etc.); and / or means for communicating according to the rate matching pattern based at least in part on the indication (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the memory 242, etc.). In some aspects, the means for the network node 110 to perform operations described herein may include, for example, one or more of the following: the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0059] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0060] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0061] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also called an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0062] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0063] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0064] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RTRIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0065] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.

[0066] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0067] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may further host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0068] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. based on functional splitting (e.g., functional splitting defined by 3GPP) (such as lower layer functional splitting). In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of communicating with the control plane and user plane of the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0069] The SMO framework 305 may be configured to support RAN deployment and configuration of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTRIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0070] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0071] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to regulate RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0072] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0073] FIG. 4A to FIG. 4B 4 is a diagram illustrating examples 400 and 450 of full-duplex communication according to the present disclosure. "Full-duplex communication" may include simultaneous uplink and downlink communications at a device (e.g., in the same time slot). For example, in example 400, a network node (network node 110, CU, DU, and / or RU) may perform a downlink transmission 410 to a first UE (e.g., UE 120, shown as UE1) and receive an uplink transmission 420 that is at least partially overlapped in time from a second UE (e.g., UE 120, shown as UE2). In other words, the network node may operate in full-duplex mode. In some examples, when the network node operates in full-duplex mode, UE1 and / or UE2 may operate in half-duplex mode. "Half-duplex communication" may refer to unidirectional communication (e.g., only downlink communication or only uplink communication) between devices at a given time (e.g., in a given time slot or a given symbol).

[0074] As shown by reference numeral 430, downlink transmissions 410 from the network node may self-interfere with uplink transmissions 420 to the network node. This may be caused by a variety of factors, such as higher transmit power and / or radio frequency leakage for downlink transmissions 410 (compared to uplink transmissions 420). In addition, as shown by reference numeral 440, downlink transmissions 410 from the network node may reflect from one or more nearby objects (such as buildings), thereby causing clutter interference with uplink transmissions 420 to the network node.

[0075] Full-duplex communication may include in-band full-duplex (IBFD) communication and sub-band full-duplex (SBFD) communication. In IBFD, the network node may perform downlink transmission 410 and receive uplink transmission 420 in the same time and frequency resources. In one example of IBFD, the time and frequency resources used for downlink communication may completely overlap with the time and frequency resources used for uplink communication. In another example of IBFD, the time and frequency resources used for downlink communication may partially overlap with the time and frequency resources used for uplink communication.

[0076] SBFD communications may also be referred to as “sub-band frequency division duplex (SBFDD)” or “flexible duplex.” In SBFD, a network node may perform downlink transmissions 410 and receive uplink transmissions 420 simultaneously but on different frequency resources (e.g., SBFD may include simultaneous transmission of downlink communications and reception of uplink communications on a sub-band basis).

[0077] Figure 4B The illustrated example 450 includes examples of time periods (e.g., time slots or symbols) used for SBFD communications. The different frequency resources used in SBFD can be sub-bands of a frequency band (e.g., of a component carrier bandwidth), such as a time division duplex band (e.g., in an unpaired spectrum and / or using an unrestricted frequency band range). In this case, the frequency resources used for downlink communications can be separated from the frequency resources used for uplink communications in the frequency domain by a guard band. In some examples, such as Figure 4B As shown, a time period (e.g., time slot or symbol) for SBFD communication may include a single uplink subband (shown as UL) between two downlink subbands (each shown as DL), and frequency resources for the uplink subband may be separated from frequency resources for the downlink subband by a corresponding guard band.

[0078] The use of SBFD can increase the uplink duty cycle (which can refer to the portion of the time period in which the UE is transmitting), thereby reducing latency (e.g., the UE may receive downlink signals in uplink-only time slots, thereby reducing latency) and / or providing improved uplink coverage. In addition, the use of SBFD can enhance the capabilities of wireless network systems, improve resource utilization and / or improve spectrum utilization. In addition, SBFD can enable resources to be flexibly and dynamically adapted to the uplink or downlink in a robust manner based on the uplink or downlink traffic. However, wireless networks as a whole lack support for techniques for signaling to the UE or otherwise indicating the time location and / or frequency location of the uplink and downlink subbands that the network node is using for SBFD operation (e.g., when the UE is operating in half-duplex mode).

[0079] Some techniques and apparatus described herein enable indicating the subband location for SBFD communication. A UE may be configured with a rate matching pattern that may identify resources to be avoided for downlink data communication. In some aspects, the rate matching pattern may be used to indicate the location of an uplink subband and one or more guard bands for SBFD communication. Because the rate matching pattern may also be used for legacy rate matching operations (e.g., in LTE, which may coexist with NR in the same channel or in an adjacent channel), the UE may receive an indication of whether the rate matching pattern is being used to indicate the location of the uplink subband and guard band for SBFD communication. Therefore, knowing that the rate matching pattern involves SBFD (e.g., rather than legacy operation), the UE may prepare and use a digital filter and / or perform other optimizations for SBFD based at least in part on the rate matching pattern. In this way, using a digital filter based at least in part on the rate matching pattern and / or other optimizations based at least in part on the rate matching pattern may improve downlink reception in SBFD communication.

[0080] As indicated above, FIG. 4A to FIG. 4B are provided as examples. Other examples can be found in the FIG. 4A to FIG. 4B The content described is different.

[0081] Figure 5 5 is a diagram of an example 500 associated with indicating subband locations for SBFD according to the present disclosure. Figure 5 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in a Figure 5 The illustrated operations are preceded by an established wireless connection. In some aspects, the network node may operate in full-duplex mode (eg, using SBFD). In some aspects, the UE may operate in half-duplex mode.

[0082] As indicated by reference numeral 505, the network node may send configuration information, and the UE may receive the configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more medium access control (MAC) control elements (CEs), and / or downlink control information (DCI), etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the UE to select (e.g., known to the UE and / or previously indicated by the network node or other network device) and / or explicit configuration information for the UE to configure the UE, etc.

[0083] In some aspects, the configuration information may indicate a configuration for a rate matching mode. The rate matching mode may identify resources that are to be avoided for downlink data communications (e.g., for physical downlink shared channel (PDSCH) communications). For example, the rate matching mode may identify frequency locations (e.g., may identify multiple resource elements) in one or more time periods (e.g., time slots) in which downlink data allocations (e.g., PDSCH allocations) are not allowed.

[0084] In one example, the configuration information may include a rate matching mode information element indicating a configuration for a rate matching mode. The rate matching mode information element may indicate a rate matching mode identifier and a rate matching mode type, among other examples. The rate matching mode type may be a selection between a control resource set or a bitmap. For example, if the configuration for the rate matching mode indicates a control resource set (e.g., by a control resource set identifier), the resources associated with the control resource set may be resources that will be avoided for downlink data communication. As another example, if the configuration for the rate matching mode indicates a bitmap, the resources indicated by the bitmap may be resources that will be avoided for downlink data communication. The bitmap may include a first bitmap identifying a resource block in a rate matching mode, a second bitmap identifying a symbol in a resource block in a rate matching mode, and / or a third bitmap identifying a time periodicity and / or a time mode of a rate matching mode (e.g., identifying a time slot in which a rate matching mode is used). The first bitmap, the second bitmap, and the third bitmap may together identify the time and frequency resources of the rate matching mode. Thus, the bitmap of the rate matching mode information element may indicate a rate matching mode.

[0085] In legacy operation, the rate matching pattern may be used to indicate resources that will not be used for downlink data communications. In other words, the transmission and reception of downlink data communications may be rate matched around (e.g., avoiding) the resources identified by the rate matching pattern. In aspects described herein, the rate matching pattern may be used additionally or alternatively to inform the UE of the frequency location and / or time location of the subband that the network node is using for SBFD operation. That is, the rate matching pattern may be reused (e.g., transferred to) indicate the location of the subband used for SBFD communication.

[0086] As shown by reference numeral 510, the network node may send and the UE may receive an indication of whether the rate matching mode indicates the position (e.g., frequency position and / or time position) of the uplink subband and at least one guard band for SBFD communication (e.g., the combined position of the uplink subband and the guard band). That is, the indication may be whether the rate matching mode is for SBFD communication (or for legacy communication). In some aspects, when the indication is that the rate matching mode is for SBFD communication, the rate matching mode may indicate the position (e.g., frequency position and / or time position) of one or more subbands being used by the network node for SBFD operation. In some aspects, rate matching mode signaling may be used (e.g., transferred) to provide the indication.

[0087] In some aspects, the indication may be a flag in a rate matching mode information element indicating a configuration for the rate matching mode (e.g., a subband indication flag). In this case, the indication may be provided in the configuration information described in conjunction with reference numeral 505. That is, the configuration and indication for the rate matching mode may be provided to the UE in the same message.

[0088] The flag may have a first value to indicate that the rate matching mode is used for SBFD communication (e.g., the first value indicates that the rate matching mode indicates the location of the uplink subband and the guard band for SBFD communication) or a second value to indicate that the rate matching mode is used for legacy operation. The flag may be located in a bitmap parameter of a mode type parameter of a rate matching mode information element. That is, the flag may be associated with a bitmap selection in a rate matching mode information element. Thus, when the flag is set to indicate that the rate matching mode is used for SBFD communication, the bitmap located in the rate matching mode information element (e.g., the resources indicated by the bitmap) may be mapped to the uplink subband and the guard band for SBFD communication. That is, the flag may indicate the diversion of a bitmap used to indicate the location of an uplink subband and a guard band.

[0089] In some aspects, the indication may be in the DCI, and the DCI may also indicate that the rate matching mode is to be used by the UE. In other words, the rate matching mode information element may not include the indication (e.g., the rate matching mode information element is not modified from the legacy use), and the DCI may indicate whether the rate matching mode indicated in the DCI is for SBFD communication or for legacy operation. For example, the indication may be in a tag field (e.g., using 1 bit) of the DCI (e.g., in DCI format 1_1 or DCI format 1_2). The tag field may be associated with the rate matching indicator field of the DCI. The rate matching indicator field may include a rate matching indicator indicating one or more rate matching modes to be used. The rate matching indicator may be 0 bits, 1 bits, or 2 bits based at least in part on higher layer parameters for the first rate matching mode group (e.g., rateMatchPatternGroup1) and the second rate matching mode group (e.g., rateMatchPatternGroup2). When there are two groups, the most significant bit of the rate matching indicator may indicate the first rate matching mode group, and the least significant bit of the rate matching indicator may indicate the second rate matching mode group.

[0090] In some aspects, the indication may include information identifying a set of resource blocks for uplink subbands and guard bands in a rate matching mode information element that indicates a configuration for a rate matching mode. In this case, the information may be provided in the configuration information described in conjunction with reference numeral 505. That is, the configuration and indication for the rate matching mode may be provided to the UE in the same message.

[0091] The information identifying a resource block set (e.g., a subband resource block set) may be a selection of a rate matching mode type parameter of a rate matching mode information element. For example, the rate matching mode type may be a selection between a control resource set, a bitmap, or a resource block set. Thus, when present in a rate matching mode information element, the information identifying the resource block set may provide an indication, and the identified resource block set may be mapped to an uplink subband and a guard band for SBFD communication. The information may identify a resource block set by a resource block set identifier (e.g., a subband resource block set identifier). For example, a plurality of resource block sets associated with a corresponding resource block set identifier may be configured for a UE (e.g., using a resource block set information element of configuration information). Each resource block set may define a specific bandwidth for an uplink subband and a guard band, for example, by a starting resource block and an ending resource block.

[0092] Indication of a rate matching mode indicating the location of uplink subbands and guard bands may inform the UE to perform rate matching around uplink subbands and guard bands for downlink reception (e.g., PDSCH reception) in SBFD symbols and / or time slots. In some cases, information identifying the guard band bandwidth / resource block and the uplink subband bandwidth / resource block, respectively, may be useful to the UE (e.g., when the UE is preparing a digital filter).

[0093] As indicated by reference numeral 515, the network node may send and the UE may receive information identifying a first position of an uplink subband, a second position of a guard band, and / or a third position of at least one downlink subband for SBFD communication. That is, information for uplink subbands, guard bands, and / or downlink subbands may be signaled separately. Information for uplink subbands, guard bands, and / or downlink subbands may be provided to the UE in addition to a rate matching pattern indicating the positions of the uplink subbands and guard bands (e.g., because the positions of the uplink subbands and guard bands indicated by the rate matching pattern may not indicate which portion of the position is associated with the uplink subband and which portion of the position is associated with the guard band).

[0094] In some aspects, the information may identify a first position of an uplink subband by indicating a bandwidth of the uplink subband (e.g., by a starting resource block and an ending resource block), may identify a second position of a guard band by indicating a bandwidth of the guard band (e.g., by a starting resource block and an ending resource block), and / or may identify a third position of a downlink subband by indicating a bandwidth of the downlink subband (e.g., by a starting resource block and an ending resource block). In some aspects, the network node may send via RRC signaling (e.g., in a semi-static manner) or in a MAC-CE or in a DCI (e.g., in a dynamic manner) and the UE may receive the information identifying the first position, the second position, and / or the third position.

[0095] As shown by reference numeral 520, the network node and the UE may communicate according to the rate matching mode based at least in part on the indication. For example, if the indication indicates that the rate matching mode is for SBFD communication (e.g., the rate matching mode indicates the location of the uplink subband and the guard band), then the downlink communication (e.g., PDSCH communication) between the network node and the UE may be rate matched around (e.g., avoiding) the uplink subband and the guard band in the SBFD symbols and / or time slots. For example, to communicate according to the rate matching mode based at least in part on the indication, in the time period (e.g., time slot or symbol) configured for SBFD communication, the network node may send and the UE may receive downlink communication (e.g., PDSCH communication) that is rate matched around the uplink subband and the guard band according to the rate matching mode. In the case where it is known that the rate matching mode involves SBFD (e.g., instead of legacy operation), the UE may prepare and use a digital filter based at least in part on the rate matching mode to improve downlink reception in SBFD communication.

[0096] In some aspects, as shown by reference numeral 525, when communicating according to a rate matching pattern based at least in part on the indication, the UE may suppress measuring a channel state information reference signal (CSI-RS) and / or another type of reference signal that overlaps (e.g., in frequency and / or time) with the rate matching pattern. For example, in response to a rate matching pattern indicating the location of an uplink subband and a guard band, the UE may suppress measuring the CSI-RS. Therefore, the UE may not expect (e.g., according to a rule) to measure a CSI-RS that overlaps with the rate matching pattern (e.g., indicating an uplink subband and a guard band). Therefore, the UE may measure the CSI-RS and / or another type of reference signal only in the downlink subband used for SBFD communication.

[0097] As indicated above, Figure 5 are provided as examples. Other examples can be found in relation to Figure 5 The examples described are different.
