[0002] This patent application claims priority to U.S. Patent Application No. 17 / 808,907, filed on June 24, 2022, entitled “CHANNEL STATE INFORMATION REFERENCE RESOURCE DEFINITION IN FULL-DUPLEX COMMUNICATION MODES” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of and is 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 associated with channel state information (CSI) reference resource definition in a full-duplex communication mode. 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 a user equipment (UE) or multiple UEs. A UE may communicate with a 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 improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using 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, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0007] In some cases, one or more CSI parameters included in a channel state information (CSI) report are calculated based on a hypothetical data transmission scheduled in a "CSI reference resource". For example, in the frequency domain, a CSI reference resource for a serving cell is defined by a set of downlink physical resource blocks corresponding to the frequency band to which the derived CSI relates. In the time domain, the CSI reference resource defines a reference downlink timeslot number as a timing reference for determining the end of a measurement window for a CSI report (e.g., a CSI report should not include any channel and / or interference measurements obtained after the reference downlink timeslot number). In addition, the CSI reference resource typically defines various properties of the hypothetical data transmission used to calculate the CSI parameters (e.g., reference signal overhead, bandwidth, and / or precoding, etc.). For example, in a case where a user equipment (UE) is configured to report one or more CSI parameters based on a hypothetical data transmission in a CSI reference resource, the UE typically assumes, among other things, that a bandwidth is configured for the corresponding CSI parameter and that no resource elements (REs) are allocated to a zero power (ZP) CSI reference signal (CSI-RS).

[0008] However, in cases where the UE is configured to communicate in full-duplex mode, one or more assumptions about the CSI reference resources may not hold. For example, as described above, the UE typically assumes that the bandwidth of the CSI reference resources is the same as that configured for the corresponding CSI parameters, and further assumes that no REs are allocated for the ZP CSI-RS for rate matching. Therefore, because the sub-band full-duplex (SBFD) mode is associated with non-contiguous downlink frequency resources, it may be necessary to adapt the CSI-RS resource configuration for full-duplex communication (e.g., because a portion of the bandwidth cannot be used for the downlink). For example, in an SBFD mode associated with non-contiguous downlink frequency resources, a CSI report may be linked to two disjoint CSI-RS resources (e.g., a first CSI-RS resource in a first subband and a second CSI-RS resource in a second subband), or a CSI report may be linked to one non-contiguous CSI-RS resource that can be defined by a start and end resource block or based on a bitmap. Therefore, because CSI reference resources are typically used to carry hypothetical downlink data transmissions, some aspects described herein relate to CSI reference resource definitions that may be based on one or more non-contiguous resource allocations that may be available for downlink data transmissions and / or uplink data transmissions in a SBFD time slot, where the mid-frequency region is used for uplink only.

[0009] For example, in some aspects, downlink and / or uplink data transmission may be associated with a configuration that explicitly defines disjoint frequency domain resources. In such cases, there may be a frequency domain resource allocation (FDRA) specific to the SBFD time slot, which may use a bitmap or two start and length indicators to explicitly define disjoint frequency domain resources. For example, FDRA may map data transmission to resource blocks that can be used for downlinks in SBFD time slots. Alternatively, non-continuous frequency domain allocation may be based on continuous data allocation across the entire bandwidth portion, and a rate matching mode is defined to implement non-continuous frequency domain allocation. In this case, one or more ZP CSI-RS resources are defined to perform rate matching around an uplink subband (e.g., one or more ZP CSI-RS resources include time and frequency resources in which no signal is sent). In this way, combining continuous resource allocation with a rate matching mode removes the uplink frequency region from the continuous resource allocation, resulting in the use of non-continuous frequency domain allocation in the SBFD time slot. Additionally, some aspects described herein relate to techniques for indicating a duplex mode for a CSI report (eg, using non-contiguous frequency domain allocation), correlating a CSI report with a CSI-RS configuration, and / or configuring CSI reference resources for different duplex modes.

[0010] Some aspects described herein relate to a UE for wireless communication. The UE may include a memory and one or more processors, the one or more processors being coupled to the memory.

The one or more processors may be configured to obtain one or more measurements of a CSI reference resource in the one or more CSI-RS resources based at least in part on the duplex mode associated with the CSI report.

[0033] 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. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the 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 present 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 devices or methods that are practiced using other structures, functionality, or structures and functionality in addition to or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0034] 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 may 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.

[0035] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0036] 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, as well as other examples. 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), one 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)).

[0037] 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 the 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 interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0038] 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. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0039] In some aspects, the term "base station" or "network node" may refer to an aggregated 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 network node 110). In some aspects, the term "base station" or "network node" may refer to multiple 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.

[0040] 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 can relay transmissions for other UEs 120. Figure 1 In the example shown, 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.

[0041] 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).

[0042] 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 these 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 backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0043] 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 medium or a wired medium.

[0044] 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, which 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, a processor component and a 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.

[0045] 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.

[0046] 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) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, or vehicle-to-pedestrian (V2P) protocol) and / or mesh network. 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.

[0047] 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 ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0048] 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 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0049] 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. In addition, 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.

[0050] In some aspects, UE 120 may include a communication manager 140. As described in greater detail elsewhere herein, communication manager 140 may receive a configuration of a channel state information (CSI) reference signal (CSI-RS) report associated with one or more CSI resources from network node 110; determine a duplex mode associated with the CSI report; obtain one or more measurements of a CSI reference resource in the one or more CSI-RS resources based at least in part on the duplex mode associated with the CSI report; and send the CSI report based at least in part on the one or more measurements of the CSI reference resource to the network node 110. Additionally or alternatively, communication manager 140 may perform one or more other operations described herein.

[0051] In some aspects, the network node 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may send a configuration of a CSI report associated with one or more CSI-RS resources to a UE 120, wherein the CSI report is associated with a duplex mode, and receive a CSI report based at least in part on one or more measurements of the CSI reference resources associated with the duplex mode from the UE 120. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0052] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different than described.

[0053] 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.

[0054] 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 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., precoding) 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 modulators) (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 upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The 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) (shown as antennas 234a through 234t).

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 sent 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, with reference to Figures 7 to 13 ) any aspects of any of the methods described herein.

[0059] 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 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 and / or uplink communications. 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 execute the instructions described herein (e.g., reference 20). Figures 7 to 13 ) any aspects of any of the methods described herein.

[0060] 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 network node 110 may perform one or more techniques associated with the CSI reference resource definition for full-duplex communication mode, as described in more detail elsewhere herein. For example, 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 Fig.10 The process of 1000 Fig.11 1100 and / or operations of 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, one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example Fig.10 The process of 1000 Fig.11 The process 1100 of , and / or the 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.

[0061] In some aspects, the UE 120 includes: means for receiving a configuration of a CSI report associated with one or more CSI-RS resources from the network node 110; means for determining a duplex mode associated with the CSI report; means for obtaining one or more measurements of a CSI reference resource in the one or more CSI-RS resources based at least in part on the duplex mode associated with the CSI report; and / or means for sending the CSI report based at least in part on the one or more measurements of the CSI reference resource to the network node 110. The means for the UE 120 to perform the operations described herein may include, for example, one or more of the following: 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.

[0062] In some aspects, the network node 110 includes means for sending a configuration of a CSI report associated with one or more CSI-RS resources to a UE 120, wherein the CSI report is associated with a duplex mode, and / or means for receiving a CSI report based at least in part on one or more measurements of CSI reference resources associated with the duplex mode from the UE 120. 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: a communications manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0063] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to 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.

[0064] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0065] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components 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 referred to as an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "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).

[0066] 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, a 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 throughout one or more other network nodes. A 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).

[0067] 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.

[0068] Figure 3 3 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 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.

[0069] 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 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 these 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, and the wireless interface may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.

[0070] In some aspects, 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 CU 310. 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, CU310 may be logically divided 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, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0071] Each DU 330 may correspond to a logical unit including 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, 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 also host one or more low PHY layers, such as by 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.

[0072] 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 based on functional splits (e.g., functional splits defined by 3GPP) such as lower layer functional splits, or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering. 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 control plane and user plane communications with 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).

[0073] The SMO framework 305 may be configured to support RAN deployment and provisioning 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-RT RIC 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.

[0074] 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.

[0075] 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 tune 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).

[0076] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0077] Figure 4 400, 405 and 410 are diagrams illustrating examples of full-duplex communication in a wireless network according to the present disclosure. As described herein, "full-duplex communication" refers to simultaneous uplink and downlink communication in a wireless network, which may be a capability of a UE, a network node, or another suitable device. For example, a UE operating in full-duplex mode may send uplink communications and receive downlink communications simultaneously (e.g., in the same time slot or the same symbol), a network node operating in full-duplex mode may receive uplink communications and send downlink communications simultaneously, etc. "Half-duplex communication" in a wireless network refers to one-way communication (e.g., only downlink communication or only uplink communication) at a given time (e.g., a device only sends or only receives in a given time slot or a given symbol).

[0078] like Figure 4 As shown, examples 400 and 405 illustrate examples of in-band full-duplex (IBFD) communications. In IBFD, a UE may send uplink communications to a network node and receive downlink communications from a network node on the same time and frequency resources. As shown in example 400, in a first example of IBFD, the time and frequency resources used for uplink communications may completely overlap with the time and frequency resources used for downlink communications (e.g., all time and frequency resources allocated to uplink communications can also be used for downlink communications). As shown in example 405, in a second example of IBFD, the time and frequency resources used for uplink communications may partially overlap with the time and frequency resources used for downlink communications (e.g., some time and frequency resources are reserved for uplink communications only).

[0079] like Figure 4As further shown, example 410 illustrates an example of sub-band full-duplex (SBFD) communication, which may also be referred to as "sub-band frequency division duplex (SBFDD)", "flexible duplex", or "frequency division duplex (FDD) in unpaired spectrum". In SBFD, a UE may send uplink communications to a network node and receive downlink communications from the network node at the same time but on different frequency resources. For example, the different frequency resources may be sub-bands of a frequency band such as a time division duplex (TDD) band. In this case, the frequency resources used for downlink communications may be separated from the frequency resources used for uplink communications in the frequency domain by a guard band.

[0080] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different than described.

[0081] Figure 5 5 is a diagram illustrating examples 500, 510, and 520 of full-duplex deployment scenarios according to the present disclosure. Figure 5 As shown, examples 500, 510 and 520 include one or more UEs communicating with one or more network nodes in a wireless network supporting full-duplex communication. In general, as described herein, utilizing a full-duplex communication mode can provide reduced latency by allowing downlink transmission to occur in only uplink time slots and / or by allowing uplink transmission to occur in only downlink time slots. In addition, by utilizing time and frequency resources for downlink communication and uplink communication simultaneously, full-duplex communication can improve the spectrum efficiency or throughput of each cell or each UE, and / or achieve more efficient resource utilization. However, as further described in detail herein, a full-duplex communication mode can be associated with a dynamic interference condition.

[0082] For example, Figure 5 As shown, example 500 includes communicating with a first network node (shown as NN) operating in full-duplex mode. 1 ) communicates with a first UE (shown as UE 1 ) and a second UE (shown as UE 2 ), wherein the first UE and the second UE operate in half-duplex mode. Figure 5As shown, the first UE may send one or more uplink transmissions to the first network node, and the second UE may concurrently receive one or more downlink transmissions from the first network node. Thus, in example 500, the first network node operates in full-duplex mode, and the first UE and the second UE each operate in half-duplex mode. As shown in example 500, there may be various forms of interference that may degrade downlink reception performance at one or more UEs and / or uplink reception performance at the first network node operating in full-duplex mode. For example, as shown in the figure, the first network node may experience interference from a second network node (shown as NN) that may be located in an adjacent or nearby cell. 2 ) caused by downlink transmissions from the first UE to the first network node. In addition, as shown, uplink transmissions from the first UE to the first network node may cause CLI at the second UE (e.g., CLI that interferes with downlink reception at the second UE). In addition, as shown, the first network node may experience self-interference, where downlink transmissions to the second UE interfere with reception of uplink transmissions from the first UE. For example, as described herein, self-interference may typically occur when a transmitted signal leaks into a receive port and / or when objects in the surrounding environment reflect a transmitted signal back to the receive port (e.g., causing a clutter echo effect), thereby interfering with reception of a desired signal at the receive port. In general, the full-duplex mode used by the first network node in Example 500 can be an SBFD mode, in which the component carrier bandwidth is divided into non-overlapping uplink and downlink subbands.

[0083] like Figure 5 As further shown, in example 510, the first UE may communicate with the first network node in full-duplex mode. For example, in example 510, the first UE may receive one or more downlink transmissions from the first network node, and the first UE may concurrently send one or more uplink transmissions to the first network node. Thus, in example 510, both the first network node and the first UE operate in full-duplex mode. In addition, as shown, the first network node may communicate with a second UE operating in half-duplex mode. Figure 5As shown, the first UE may experience self-interference, where uplink transmissions to the first network node interfere with reception of downlink transmissions from the first network node, and the first UE may cause cross-link interference at the second UE, where uplink transmissions to the first network node interfere with downlink reception at the second UE. Additionally, in example 510, the first network node may experience CLI caused by one or more downlink transmissions from the second network node interfering with reception of uplink transmissions from the first UE, and the first network node may experience self-interference, where downlink transmissions to the first UE and / or the second UE interfere with reception of uplink transmissions from the first UE. In example 510, full-duplex communication may be performed in SBFD mode (wherein the component carrier bandwidth is divided into non-overlapping uplink and downlink subbands), or full-duplex communication may be performed in IBFD mode (wherein uplink and downlink resources fully or partially overlap).

[0084] like Figure 5 As further shown, in example 520, the first UE may communicate with the first network node and the second network node in full-duplex mode (e.g., multi-TRP mode). For example, in example 520, the first UE may send one or more uplink transmissions to the first network node, and the first UE may concurrently receive one or more downlink transmissions from the second network node. Thus, in example 520, the first UE operates in full-duplex mode, and the first network node and the second network node both operate in half-duplex mode. Figure 5 As shown, the first UE may experience self-interference, where uplink transmissions to the first network node interfere with reception of downlink transmissions from the second network node. In addition, uplink transmissions performed by the first UE may cause CLI at the second UE that is receiving downlink transmissions from the second network node. In addition, as shown, downlink transmissions performed by the second network node may cause CLI that interferes with reception of uplink transmissions from the first UE at the first network node. In example 520, full-duplex communication may be performed in SBFD mode (wherein the component carrier bandwidth is divided into non-overlapping uplink and downlink subbands), or full-duplex communication may be performed in IBFD mode (wherein uplink and downlink resources fully or partially overlap).

[0085] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 Different than described.

[0086] Figure 6 600, 610, 620 are diagrams illustrating examples of different duplex modes according to the present disclosure. For example, as described in further detail herein, Figure 6An example 600 of an FDD mode that may be used in a paired spectrum, an example 610 of a TDD mode that may be used in an unpaired spectrum, and an example 620 of an SBFD mode that may be used in an unpaired spectrum are illustrated.

[0087] In some aspects, wireless communication standards and / or regulatory agencies may generally specify one or more duplex modes in which wireless spectrum is to be used. For example, 3GPP may specify how wireless spectrum is to be used for 5G / NR radio access technologies and interfaces. For example, a specification may indicate whether a frequency band is to be used as paired spectrum in FDD mode or as unpaired spectrum in TDD mode.

[0088] For example, as shown in example 600, the paired spectrum in FDD mode may use a first frequency region (or channel) for uplink communication and a second frequency region (or channel) for downlink communication. In these cases, the frequency regions or channels used for uplink communication and downlink communication do not overlap, have different center frequencies, and have sufficient spacing to prevent interference between downlink communication and uplink communication. For example, the paired spectrum in FDD mode may include an uplink operating band and a downlink operating band, which are configured to use non-overlapping frequency regions separated by guard bands. Therefore, when operating in FDD mode in a paired spectrum, a UE with full-duplex capability can perform concurrent transmission and reception operations using separate operating bands allocated to downlink and uplink communications. For example, the paired bands in NR include NR operating bands n1, n2, n3, n5, n7, n8, n12, n20, n25, and n28, as specified in 3GPP Technical Specification (TS) 38.101-1.

[0089] Alternatively, as shown in example 610, the unpaired spectrum in TDD mode may allow downlink and uplink operations within a single frequency region (e.g., a single operating band). For example, when operating in TDD mode in an unpaired spectrum, downlink communication and uplink communication may occur in the same frequency range. Some deployments may use TDD in unpaired bands, whereby some transmission time intervals (e.g., frames, time slots, and / or symbols) are used only for downlink communication, while other transmission time intervals are used only for uplink communication. In this case, depending on whether the communication is performed in a downlink interval, an uplink interval, or a special interval (in which downlink or uplink communication may be scheduled), substantially the entire bandwidth of the component carrier may be used for downlink communication or uplink communication. Examples of unpaired bands include NR operating bands n40, n41, and n50, as specified in 3GPP TS 38.101-1. However, in some cases, using TDD in an unpaired spectrum may be inefficient. For example, the uplink transmit power may be limited, which means that the UE may not be able to transmit with sufficient power to efficiently utilize the full bandwidth of the uplink time slot. This may be particularly problematic at the cell edge of a larger cell. In addition, relative to a full-duplex scheme that can perform uplink and downlink communications in the same time interval, the use of TDD may introduce latency because TDD limits the use of a given transmission time interval to only uplink or downlink communications. In addition, by limiting the use of a given transmission time interval to only uplink or downlink communications, the use of TDD may reduce spectral efficiency and / or reduce throughput.

[0090] Thus, as shown in example 620, an unpaired frequency band may be configured in full-duplex mode to enable concurrent transmit and receive operations in an unpaired frequency spectrum (e.g., a TDD frequency band). Figure 6 In the example 620, an SBFD mode is depicted, which may be referred to herein as full duplex in frequency division multiplexing (FDM) mode, to enable TDD operation and / or FDD operation in an unpaired spectrum. Figure 6As shown, an unpaired frequency band configured in SBFD mode may associate one or more transmission time intervals with downlink communications only (e.g., "D" time slots), one or more transmission time intervals with uplink communications only (e.g., "U" time slots), and one or more transmission time intervals with both downlink and uplink communications (e.g., "D+U" time slots). Each transmission time interval may be associated with a control region, which is shown as a portion of the time interval having a diagonal fill for uplink control (e.g., a physical uplink control channel (PUCCH)) or a darker shaded fill for downlink control (e.g., a physical downlink control channel (PDCCH)). Additionally or alternatively, each time interval may be associated with a data region, which is shown as a physical downlink shared channel (PDSCH) for a downlink frequency region or a physical uplink shared channel (PUSCH) for an uplink frequency region.

[0091] In some aspects, the unpaired frequency band configured in the SBFD mode may include one or more downlink-only time intervals, one or more uplink-only time intervals, and / or one or more full-duplex time intervals (e.g., frames, subframes, time slots, and / or symbols, etc.) associated with the FDD configuration. Figure 6 As shown, the FDD configuration associated with the full-duplex time interval may indicate one or more downlink frequency regions (or subbands) and one or more uplink frequency regions (or subbands) separated by a guard band. Thus, the FDD configuration may divide an unpaired frequency band (e.g., one or more component carriers of the unpaired frequency band) into an uplink frequency region, a downlink frequency region, and / or other regions (e.g., a guard band, etc.), which may enable a UE with full-duplex capability to perform simultaneous transmission and reception operations during one or more time intervals divided into downlink and uplink subbands with guard band intervals to prevent uplink transmissions from causing self-interference with respect to downlink reception. For example, in a given full-duplex time interval, a half-duplex UE may use an uplink frequency region for transmission or receive in a downlink frequency region (e.g., in the illustrated example, the UE 2 The UE may be using half-duplex for communication and may only receive in the lower downlink frequency region during full-duplex time intervals), and a full-duplex UE may use the uplink frequency region for transmission and / or receive in the downlink frequency region (e.g., in the illustrated example, the UE 1(a) The FDD configuration may be used to communicate using full duplex and thus receive in a higher downlink frequency region simultaneously with transmission in an uplink frequency region during a full duplex time interval. In some aspects, the FDD configuration may identify a bandwidth part (BWP) configuration corresponding to the uplink frequency region and the downlink frequency region. For example, a corresponding BWP may be configured for each uplink frequency region and each downlink frequency region.

[0092] Additionally or alternatively, full-duplex may be enabled in an unpaired spectrum in an IBFD mode, which may be referred to herein as full-duplex in a spatial division multiplexing (SDM) mode. For example, in an IBFD or SDM mode, uplink communications may occur on time and frequency resources that completely overlap with time and frequency resources allocated for downlink communications (e.g., all time and frequency resources that can be used for uplink communications can also be used for downlink communications), or on time and frequency resources that partially overlap with time and frequency resources that can be used for downlink communications (e.g., some time and frequency resources that can be used for uplink communications can also be used for downlink communications, and some time and frequency resources that can be used for uplink communications are uplink-only). Generally speaking, in IBFD mode, full-duplex communications may depend on sufficient beam separation between uplink beams and downlink beams (e.g., uplink transmissions may come from one antenna panel and downlink reception may be in another antenna panel) to minimize self-interference that may occur when transmitted signals leak into receive ports and / or when objects in the surrounding environment reflect transmitted signals back to receive ports (e.g., causing a spurious echo effect).

[0093] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 Different than described.

[0094] Figure 7 are diagrams illustrating examples 700 , 710 of non-contiguous frequency domain allocation for CSI reference resources in a full-duplex time slot according to the present disclosure.

[0095] In wireless networks, CSI generally includes various parameters related to properties associated with the wireless channel and / or representing how a signal propagates from a transmitter to a receiver based on the combined effects of scattering, fading, and / or power attenuation over distance. Therefore, a network node can use the CSI obtained by a UE to adapt transmissions to current channel conditions, which can increase reliability and / or throughput in a wireless network.

[0096] The CSI is typically obtained based on one or more reference signal transmissions that can be used for downlink and / or uplink channel estimation. For example, in some aspects, the CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition), which a network node may use for scheduling, link adaptation, or beam management, etc. The network node may configure the CSI-RS for the UE, and the UE may measure the configured CSI-RS. Based at least in part on the measurements, the UE may perform channel estimation and may report channel estimation parameters (e.g., in a CSI report) such as CQI, precoding matrix indicator (PMI), CSI-RS resource indicator (CRI), layer indicator (LI), rank indicator (RI), or RSRP, etc. to the base station. The network node may use the CSI report to select transmission parameters for downlink communication with the UE, such as the number of transmission layers (e.g., rank), precoding matrix (e.g., precoder), MCS, or refined downlink beams (e.g., using a beam refinement procedure or a beam management procedure), etc.

[0097] In some cases, one or more CSI parameters included in a CSI report (e.g., CQI) are calculated based on a hypothetical PDSCH transmission scheduled in a "CSI reference resource" (e.g., as defined in 3GPP TS 38.214, Section 5.2.2.5). For example, in the frequency domain, the CSI reference resources for a serving cell are defined by a set of downlink physical resource blocks corresponding to the frequency band to which the derived CSI relates. In the time domain, the CSI reference resources define a reference downlink slot number as a timing reference for determining the end of the measurement window for the CSI report (e.g., the CSI report should not include any channel and / or interference measurements obtained after the reference downlink slot number). In addition, the CSI reference resources typically define various properties of the hypothetical PDSCH transmission used to calculate the CSI parameters (e.g., reference signal overhead, bandwidth and / or precoding, etc.). For example, in a case where the UE is configured to report one or more CSI parameters (e.g., CQI index, PMI, RI, etc.) based on an assumed PDSCH transmission in a CSI reference resource, the UE typically assumes that the first two (2) symbols of the CSI reference resource are occupied by control signaling, the number of PDSCH and DMRS symbols is twelve (12), the BWP subcarrier spacing is the same as configured for PDSCH reception, the bandwidth is configured for the corresponding CSI parameters, the CSI reference resource uses the cyclic prefix length and subcarrier spacing configured for PDSCH reception, no resource elements are used by the primary synchronization signal, the secondary synchronization signal, or the physical broadcast channel, the redundancy version is zero (0), the ratio of PDSCH energy per resource element (EPRE) to CSI-RS EPRE has a defined value (e.g., given in 3GPP TS 38.214, clause 5.2.2.3.1), and / or no resource elements (REs) are allocated to non-zero power (NZP) CSI-RS and / or zero power (ZP) CSI-RS.

[0098] However, in the case where the UE is configured to communicate in full-duplex mode, one or more assumptions about the CSI reference resources may not hold. For example, as described above, the UE typically assumes that the bandwidth of the CSI reference resources is the same as that configured for the corresponding CSI parameters (e.g., for the corresponding CQI report), and further assumes that no REs are allocated for the ZP CSI-RS for rate matching. Therefore, because the SBFD mode is associated with non-contiguous downlink frequency resources, it may be necessary to adapt the CSI-RS resource configuration for full-duplex communication (e.g., because a portion of the bandwidth cannot be used for the downlink). For example, in an SBFD mode associated with non-contiguous downlink frequency resources, a CSI report may be linked to two disjoint CSI-RS resources (e.g., a first CSI-RS resource in a first subband and a second CSI-RS resource in a second subband), or a CSI report may be linked to one non-contiguous CSI-RS resource that can be defined by a start and end resource block or based on a bitmap. Therefore, because CSI reference resources are typically used to carry hypothetical PDSCH transmissions, some aspects described herein relate to CSI reference resource definitions that may be based on one or more non-contiguous resource allocations available for PDSCH and / or PUSCH in a SBFD time slot, where the mid-frequency region is used for uplink only.

[0099] For example, refer to Figure 7 , Example 700 illustrates a PXSCH (e.g., PDSCH and / or PUSCH) configuration that explicitly defines non-overlapping frequency domain resources. In such cases, there may be a frequency domain resource allocation (FDRA) specific to the SBFD time slot, which may explicitly define non-overlapping frequency domain resources using a bitmap or two start and length indicators. For example, as shown, the FDRA may map the PDSCH to RBs that can be used for the downlink in the SBFD time slot. Alternatively, Example 710 illustrates a non-continuous PXSCH frequency domain allocation based on continuous PDSCH allocation across the entire BWP, and a rate matching mode is defined to achieve non-continuous PXSCH frequency domain allocation. In this case, one or more ZP CSI-RS resources are defined for rate matching around the uplink subband (e.g., one or more ZP CSI-RS resources include time and frequency resources in which no signals are transmitted). In this way, combining the continuous PDSCH resource allocation with the rate matching mode removes the uplink frequency region from the continuous PDSCH resource allocation, resulting in the use of non-continuous PXSCH frequency domain allocation in the SBFD time slot. In addition, some aspects described herein (e.g., with reference to Figure 8 and Fig. 9) relates to techniques for indicating the duplex mode of a CSI report (e.g., using non-contiguous PXSCH frequency domain allocation), associating the CSI report with a CSI-RS configuration, and / or configuring CSI reference resources for different duplex modes.

[0100] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 Different than described.

[0101] Figure 8 Schematic diagrams of examples 800, 810 illustrating non-continuous CSI-RS configurations that can be used to derive CSI in full-duplex time slots according to the present disclosure. Specifically, example 800 depicts a first case in which the CSI-RS resource configuration matches the frequency domain resources of a PDSCH transmission in a full-duplex (e.g., SBFD) time slot. For example, the PDSCH transmission in a full-duplex time slot includes non-continuous frequency domain resources separated by uplink subbands, and the CSI-RS resource configuration matches the non-continuous frequency domain resources of the PDSCH transmission. In this case, as shown in example 800, sub-band CSI-RS (e.g., covering only the non-continuous frequency domain resources of the PDSCH transmission) is used to derive CSI for PDSCH transmission in a SBFD time slot. In addition, although in Figure 8 , but a wideband CSI-RS (e.g., covering the entire BWP) will be used to derive CSI for PDSCH transmissions in a downlink slot. Additionally or alternatively, example 810 depicts a second case in which the network node may configure a non-continuous CSI-RS to be used to derive wideband CSI in a SBFD slot (e.g., using interpolation) and / or configure a wideband continuous CSI-RS in a downlink slot to derive CSI for both the SBFD slot and the downlink slot. In this case, as shown, the frequency domain resources of the CSI-RS do not have to match the frequency domain resources of the PDSCH, and interpolation may be used to obtain wideband CSI based on the non-continuous CSI-RS.

[0102] In general, as described herein, different cases of CSI-RS resource configuration and CSI derivation (e.g., using non-contiguous CSI-RS resource configuration that matches the frequency-domain resources of a PDSCH transmission to derive CSI in a SBFD time slot and / or using non-contiguous CSI-RS resource configuration and interpolation to derive CSI in a downlink time slot) require different definitions of CSI reference resources (e.g., a set of resources carrying a hypothetical PDSCH transmission for deriving one or more CSI parameters), which can then be used to determine the number of REs to be used to derive one or more CSI parameters (e.g., CQI).

[0103] As indicated above, Figure 8are provided as examples. Other examples can be found in the Figure 8 Different than described.

[0104] Fig. 9 is a diagram illustrating an example 900 associated with a CSI reference resource definition in a full-duplex communication mode according to the present disclosure. Fig. 9 As shown in , example 900 includes communication between a network node 110 and a UE 120. In some aspects, the network node 110 and the UE 120 may be included in a wireless network, such as the wireless network 100. The network node 110 and the UE 120 may communicate via a wireless access link, which may include an uplink and a downlink.

[0105] like Fig. 9 As shown, and by reference numeral 910, the network node 110 may send a CSI reporting configuration associated with a set of CSI-RS resources to the UE 120. For example, in some aspects, the CSI-RS resources may include a wideband CSI-RS to be used by the UE 120 to derive CSI for a PDSCH in a downlink slot, a subband CSI-RS to be used by the UE 120 to derive CSI for a PDSCH in a SBFD slot, a non-continuous CSI-RS (e.g., using interpolation) to be used by the UE 120 to derive CSI in both a downlink slot and a SBFD slot, and / or a wideband contiguous CSI-RS to be used by the UE 120 to derive CSI in both a downlink slot and a SBFD slot. Thus, because a hypothetical PDSCH transmission associated with a CSI reference resource may be sent in a downlink (or half-duplex) slot or a SBFD (or full-duplex) slot associated with different frequency-domain resource allocations, the UE 120 may need to distinguish between full-duplex and half-duplex CSI reports.

[0106] As indicated by reference numeral 920, UE 120 may determine a duplex mode for a CSI report. For example, in some aspects, UE 120 may determine a duplex mode for a CSI report based on frequency domain resources of a CSI-RS resource associated with the CSI report. For example, in a case where the CSI report is associated with a non-contiguous CSI-RS resource, the duplex mode for the CSI report may be SBFD, or in a case where the CSI report is associated with a contiguous CSI-RS resource, the duplex mode for the CSI report may be half-duplex. Alternatively, in some aspects, the duplex mode for the CSI report may be independent of the frequency domain allocation of the CSI-RS resource associated with the CSI report. For example, rather than being dependent on the frequency domain allocation of the CSI-RS resource associated with the CSI report, the duplex mode for the CSI report may be explicitly indicated in a CSI report configuration provided by network node 110 and / or in a downlink control information (DCI) message that triggers the transmission of a CSI report associated with the CSI report configuration. For example, in such cases, the CSI reporting configuration and / or triggering DCI may include a binary indication of half-duplex mode or full-duplex mode for CSI reporting. Alternatively, the CSI reporting configuration and / or triggering DCI may include an explicit definition of a non-contiguous bandwidth to be used by the UE 120 for CSI derivation. In the latter case, indicating the duplex mode in the CSI reporting configuration and / or triggering DCI may provide the network node 110 with greater flexibility to link the same set of CSI-RS resources to half-duplex CSI reporting and full-duplex CSI reporting.

[0107] As shown in the figure 930, the UE 120 may update the definition of the CSI reference resources based on the duplex mode of the CSI report. For example, as described herein, one or more CSI parameters included in the CSI report (e.g., CQI) may be calculated based on a hypothetical PDSCH transmission scheduled in a CSI reference resource, which is defined by a set of downlink physical resource blocks corresponding to the frequency band involved in the derived CSI in the frequency domain. Among other assumptions, the UE 120 typically assumes that the bandwidth of the CSI reference resource is the same as that configured for the corresponding CSI report. Therefore, it may be necessary to update the definition of the CSI reference resources to take into account the situation where the PXSCH configuration explicitly defines non-intersecting frequency domain resources (such as non-intersecting downlink and uplink frequency regions used in SBFD time slots). Specifically, the UE 120 may update the definition of the CSI reference resources to reflect the PXSCH frequency domain resources associated with half-duplex and / or SBFD time slots. For example, in some aspects, the bandwidth of the CSI reference resources may be contiguous for half-duplex CSI reporting or non-contiguous for SBFD CSI reporting. Thus, the UE 120 may determine the number of available REs associated with the CSI reference resources based on the bandwidth of the CSI reference resources (which depends on the duplex mode of the CSI reporting), which may affect the CQI or other CSI parameters calculated based on the assumed PDSCH transmission in the CSI reference resources. For example, in some aspects, one or more downlink subbands to be considered as part of the CSI reference resources may be defined in the wireless communication standard, or the downlink subbands may be adjusted based on the bandwidth of the CSI reporting configuration.

[0108] Additionally or alternatively, in the case where a rate matching mode is used to implement non-contiguous PXSCH frequency domain allocation in the SBFD time slot (e.g., as described above with reference to Figure 7As described herein), the UE 120 may update the definition of CSI reference resources to include ZP-CSI-RS resources for full-duplex CSI reporting. For example, as described herein, another assumption that the UE 120 typically applies to CSI reference resources is that there are no REs allocated to ZP-CSI-RS resources. However, this assumption may be incorrect in the case where a rate matching mode is used to implement non-contiguous PXSCH frequency domain allocation in a SBFD time slot, where the ZP-CSI-RS resources are defined to be rate matched around the uplink subband. Therefore, in the case where the CSI report is determined to be a full-duplex CSI report, the UE 120 may update the definition of CSI reference resources to include ZP-CSI-RS resources in order to capture the non-contiguous frequency domain resources (note that the definition of CSI reference resources does not need to be updated in the case of half-duplex CSI reporting because there will not be any ZP-CSI-RS resources defined in the downlink time slot where full PDSCH allocation is used). In some aspects, when the definition of CSI reference resources is updated to include ZP-CSI-RS resources for full-duplex CSI reporting, the number of REs allocated to the ZP-CSI-RS may be defined as a fixed number, defined based on a fixed partition between uplink resource allocation and downlink resource allocation, or may be adjusted based on the CSI reporting configuration.

[0109] As further shown by reference numeral 940, UE 120 may then obtain measurements of CSI reference resources based on the duplex mode of the CSI report, including any updates to the definition of the CSI reference resources based on the duplex mode of the CSI report. As shown by reference numeral 950, UE 120 may send a CSI report to network node 110 based on the measurements of the CSI reference resources. For example, UE 120 may calculate CQI, PMI, RI, and / or other suitable CSI parameters based on a hypothetical PDSCH transmission scheduled in the CSI reference resources, where the calculation of the CSI parameters may depend on whether the CSI report is a half-duplex or full-duplex report. In this way, the network node may use the CSI report to select transmission parameters for downlink communications to UE 120 in half-duplex and / or full-duplex time slots. For example, the network node may use the CSI report to select transmission parameters such as the number of transmission layers (e.g., rank), precoding matrix (e.g., precoder), and / or MCS, etc.

[0110] As indicated above, Fig. 9 are provided as examples. Other examples can be found in the Fig. 9 Different than described.

[0111] Fig.10is a diagram illustrating an example process 1000 performed, for example, by a UE in accordance with the present disclosure. Example process 1000 is an example in which a UE (eg, UE 120) performs operations associated with CSI reference resource definition in a full-duplex communication mode.

[0112] like Fig.10 As shown, in some aspects, process 1000 may include receiving a configuration of a CSI report associated with one or more CSI-RS resources from a network node (block 1010). For example, a UE (e.g., using Fig.12 The depicted communications manager 140 and / or receiving component 1202) may receive, from a network node, a configuration of a CSI report associated with one or more CSI-RS resources, as described above.

[0113] like Fig.10 As further shown, in some aspects, process 1000 may include determining a duplex mode associated with a CSI report (block 1020). Fig.12 The communication manager 140 and / or CSI reporting component 1208 depicted in FIG. 1 may determine a duplex mode associated with a CSI report, as described above.

[0114] like Fig.10 As further shown, in some aspects, process 1000 may include obtaining one or more measurements of CSI reference resources of one or more CSI-RS resources based at least in part on a duplex mode associated with the CSI report (block 1030). Fig.12 The communication manager 140 and / or CSI reporting component 1208 depicted in FIG. 1 may obtain one or more measurements of CSI reference resources of one or more CSI-RS resources based at least in part on a duplex mode associated with the CSI report, as described above.

[0115] like Fig.10 As further shown, in some aspects, process 1000 may include sending a CSI report based at least in part on one or more measurements of a CSI reference resource to a network node (block 1040). Fig.12 The communication manager 140 and / or the sending component 1204 depicted in FIG. 1 may send a CSI report to a network node based at least in part on one or more measurements of a CSI reference resource, as described above.

[0116] Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0117] In a first aspect, the duplex mode associated with the CSI report is determined based at least in part on a frequency domain resource allocation of the one or more CSI-RS resources associated with the CSI report.

[0118] In a second aspect, alone or in combination with the first aspect, the duplex mode is determined to be full duplex based at least in part on the one or more CSI-RS resources having non-contiguous frequency domain resource allocation.

[0119] In a third aspect, alone or in combination with one or more of the first and second aspects, the duplex mode is determined to be half-duplex based at least in part on the one or more CSI-RS resources having a continuous frequency domain resource allocation.

[0120] In a fourth aspect, either alone or in combination with one or more of the first to third aspects, the duplex mode associated with the CSI report is indicated in the configuration of the CSI report or in a DCI received by the UE, which triggers the sending of the CSI report.

[0121] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the configuration of the CSI report or the DCI triggering the sending of the CSI report comprises a binary indication of a half-duplex mode or a full-duplex mode for the CSI report.

[0122] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the configuration of the CSI report or the DCI triggering the sending of the CSI report indicates the duplex mode used for the CSI report according to a continuous or non-continuous bandwidth used for CSI derivation.

[0123] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, process 1000 includes determining a bandwidth of the CSI reference resource based at least in part on the duplex mode associated with the CSI report.

[0124] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the bandwidth of the CSI reference resource is determined to be continuous based at least in part on the duplex mode associated with the CSI report being half-duplex.

[0125] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the bandwidth of the CSI reference resource is determined to be non-contiguous based at least in part on the duplex mode associated with the CSI report being full-duplex.

[0126] In a tenth aspect, alone or in combination with one or one of the first to ninth aspects, the CSI reference resources include one or more REs allocated to ZP-CSI-RS resources based at least in part on the duplex mode associated with the CSI report being full duplex.

[0127] In an eleventh aspect, alone or in combination with one or more of the first to tenth aspects, the number of the one or more REs allocated to the ZP-CSI-RS resource has a fixed value.

[0128] In a twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, the number of the one or more REs allocated to the ZP-CSI-RS resource is based at least in part on a fixed division between uplink resources and downlink resources.

[0129] In a thirteenth aspect, alone or in combination with one or more of the first to twelfth aspects, the number of the one or more REs allocated to the ZP-CSI-RS resource is based at least in part on the configuration of the CSI report.

[0130] although Fig.10 An example block diagram of process 1000 is shown, but in some aspects, process 1000 may include Fig.10 Additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in the process 1000. Additionally or alternatively, two or more of the blocks in the process 1000 may be performed in parallel.

[0131] Fig.11 is a diagram illustrating an example process 1100, performed, for example, by a network node, in accordance with the present disclosure. The example process 1100 is an example in which a network node (eg, network node 110) performs operations associated with CSI reference resource definition in a full-duplex communication mode.

[0132] like Fig.11 As shown, in some aspects, process 1100 may include sending a configuration of a CSI report associated with one or more CSI-RS resources to a UE, wherein the CSI report is associated with a duplex mode (block 1110).

The UE of claim 16, wherein the CSI reference resources comprise one or more resource elements (REs) allocated to zero power (ZP)-CSI-RS resources based at least in part on the duplex mode associated with the CSI report being full duplex. 27 . The UE of claim 26 , wherein the number of the one or more REs allocated to the ZP-CSI-RS resources has a fixed value.

28. The UE of claim 26, wherein the number of the one or more REs allocated to the ZP-CSI-RS resources is based at least in part on a fixed partition between uplink resources and downlink resources.

29. The UE of claim 26, wherein the number of the one or more REs allocated to the ZP-CSI-RS resources is based at least in part on the configuration of the CSI report.

30. A network node for wireless communication, the network node comprising: Memory; and one or more processors coupled to the memory and configured to: sending a configuration of a channel state information (CSI) report associated with one or more CSI reference signal (CSI-RS) resources to a user equipment (UE), wherein the CSI report is associated with a duplex mode; as well as A CSI report is received from the UE based at least in part on one or more measurements of a CSI reference resource associated with the duplex mode.
