[0004] A wireless communication system may include one or more network communication devices (such as base stations), which may also be referred to as eNodeB (eNB), next generation NodeB (gNB) or other suitable terms. Each network communication device (such as a base station) may support wireless communication of one or more user communication devices, which may also be referred to as user equipment (UE) or other suitable terms. A wireless communication system may support wireless communication with one or more user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers). In addition, a wireless communication system may support wireless communication across various radio access technologies, including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, and other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)).

[0005] In unpaired spectrum, time division duplex (TDD) can be used to avoid interference (e.g., uplink and downlink interference within a network entity, and UE-to-UE interference). However, TDD limits uplink (UL) and downlink (DL) transmission opportunities and makes it difficult to accommodate UL and DL transmissions simultaneously, such as when the DL and UL traffic in a cell is asymmetric. Summary of the invention

[0025] In some wireless communication systems for unpaired spectrum, TDD is used to avoid interference (e.g., uplink and downlink interference within a network entity, and UE-to-UE interference). However, TDD may limit UL and DL transmission opportunities, and may lead to challenges in accommodating emergency UL and DL transmissions at the same time, such as when the DL and UL traffic in a cell are asymmetric. In addition, CLI measurement and reporting mechanisms have been specified to handle co-channel and adjacent channel interference, as well as UE-to-UE interference. However, existing CLI measurement and reporting mechanisms mainly address CLI caused by different TDD UL and DL configurations across adjacent cells, and provide limited CLI measurement resources, which leads to inefficient CLI measurement and increased signaling overhead.

[0026] Therefore, the present disclosure provides for configuring full-duplex UL and DL subbands for full-duplex operation in a cell, and measuring cross-link interference for subband-based full-duplex operation, such as when a serving network entity performs simultaneous reception and transmission in non-overlapping subbands within a carrier. For example, the network entity may configure a first subband of a carrier as an UL resource and a second subband of the carrier that does not overlap with the first subband as a DL resource for full-duplex cell operation within the carrier. The UE may utilize UL resources and DL resources as part of subband-based full-duplex operation. In addition, interference measurements for subband-based full-duplex operation are provided, such as to implement enhanced time domain CLI measurement configurations. For example, the UE receives a CLI measurement configuration included in a DL bandwidth part (BWP) configuration, wherein the CLI measurement configuration configures multiple measurement time instances or measurement opportunities (e.g., multiple measurement time slots) within a measurement period. The UE may then perform CLI measurements using multiple time instances, and may generate interference information (e.g., a measurement report) based on the CLI measurements.

[0027] Thus, by enabling full duplex operation by the network entity and optionally by the UE, latency may be reduced by allowing controlled UL and DL transmissions, such as when ongoing DL and UL traffic is being served in a carrier. In addition, by enabling interference measurements to be performed at multiple time instances based on information of the full duplex UL subband, signaling overhead is reduced and the speed at which interference measurements are performed is increased.

[0028] Aspects of the present disclosure are described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described with reference to device diagrams and flow charts.

[0029] Figure 1 An example of a wireless communication system 100 supporting subband-based full-duplex operation according to various aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 102, one or more UEs 104, a core network 106, and a packet data network 108. The wireless communication system 100 may support various radio access technologies. In some implementations, the wireless communication system 100 may be a 4G network, such as an LTE network or an advanced LTE (LTE-A) network. In some other implementations, the wireless communication system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communication system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technologies, including the Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20. The wireless communication system 100 may support radio access technologies other than 5G. In addition, the wireless communication system 100 may support technologies such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA).

[0030] One or more network entities 102 may be dispersed throughout a geographic area to form a wireless communication system 100. One or more network entities 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a radio access network (RAN), a base transceiver station, an access point, a NodeB, an eNodeB (eNB), a next generation NodeB (gNB), or other suitable terms. The network entity 102 and the UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, the network entity 102 and the UE 104 may perform wireless communication (e.g., receive signaling, send signaling) over a Uu interface.

[0031] The network entity 102 may provide a geographic coverage area 112 for which the network entity 102 supports services (e.g., voice, video, packet data, messaging, broadcast, etc.) for one or more UEs 104 within the geographic coverage area 112. For example, the network entity 102 and the UE 104 may support wireless communications of signals associated with services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or more radio access technologies. In some implementations, the network entity 102 may be mobile, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but different geographic coverage areas 112 may be associated with different network entities 102. The information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout the description may be represented by voltage, current, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0032] One or more UEs 104 may be dispersed throughout the geographic area of ​​the wireless communication system 100. UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, a subscriber device, or some other suitable term. In some implementations, UE 104 may be referred to as a unit, a station, a terminal, or a client, etc. Additionally or alternatively, UE 104 may be referred to as an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc. In some implementations, UE 104 may be stationary in the wireless communication system 100. In some other implementations, UE 104 may be mobile in the wireless communication system 100.

[0033] One or more UEs 104 may be devices of different forms or with different capabilities. Figure 1 Some examples of UE 104 are illustrated in FIG. Figure 1 As shown, UE 104 can communicate with various types of devices, such as network entity 102, other UE 104, or network equipment (e.g., core network 106, packet data network 108, relay device, integrated access and backhaul (IAB) node, or another network device). Additionally or alternatively, UE 104 can support communication with other network entities 102 or UE 104 that can act as relays in wireless communication system 100.

[0034] The UE 104 may also be capable of supporting wireless communications directly with other UEs 104 via a communication link 114. For example, the UE 104 may support wireless communications directly with another UE 104 via a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular V2X deployments, the communication link 114 may be referred to as a sidelink. For example, the UE 104 may support wireless communications directly with another UE 104 via a PC5 interface.

[0035] The network entity 102 may support communication with the core network 106 or with another network entity 102 or both. For example, the network entity 102 may interface with the core network 106 via one or more backhaul links 116 (e.g., via S1, N2, N2 or another network interface). The network entities 102 may communicate with each other via the backhaul links 116 (e.g., via X2, Xn or another network interface). In some implementations, the network entities 102 may communicate directly with each other (e.g., between the network entities 102). In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106). In some implementations, one or more network entities 102 may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). The ANC may communicate with one or more UEs 104 via one or more other access network transport entities (which may be referred to as radio heads, smart radio heads, or transport reception points (TRPs)).

[0036] In some implementations, the network entity 102 may be configured in a decomposed architecture that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 102, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 102 may include one or more of a central unit (CU), a distributed unit (DU), a radio unit (RU), a RAN intelligent controller (RIC) (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) system, or any combination thereof.

[0037] The RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). In a decomposed RAN architecture, one or more components of the network entity 102 may be co-located, or one or more components of the network entity 102 may be located in distributed locations (e.g., separate physical locations). In some implementations, one or more network entities 102 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0038] The functional split between CU, DU and RU can be flexible, and different functions can be supported depending on the functions performed at the CU, DU or RU (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions and any combination thereof). For example, a functional split of a protocol stack can be adopted between a CU and a DU so that the CU can support one or more layers of the protocol stack and the DU can support one or more different layers of the protocol stack. In some implementations, the CU can host higher-level protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functions and signaling (e.g., Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). The CU can be connected to one or more DUs or RUs, and one or more DUs or RUs can host lower protocol layers, such as Layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, media access control (MAC) layer) functions and signaling, and each can be at least partially controlled by the CU.

[0039] Additionally or alternatively, a functional split of the protocol stack may be employed between the DU and the RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or more different cells (e.g., via one or more RUs). In some implementations, the functional split between the CU and the DU or between the DU and the RU may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of the CU, the DU, or the RU, while other functions of the protocol layer may be performed by different ones of the CU, the DU, or the RU).

[0040] The CU may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU may be connected to one or more DUs via a medium-range communication link (e.g., F1, F1-c, F1-u), and the DU may be connected to one or more RUs via a fronthaul communication link (e.g., an open fronthaul (FH) interface). In some implementations, the medium-range communication link or the fronthaul communication link may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by the corresponding network entity 102 communicating via the communication link.

[0041] The core network 106 may support user authentication, access authorization, tracking, connection, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) or a 5G core (5GC), which may include control plane entities that manage access and mobility (e.g., mobility management entity (MME), access and mobility management function (AMF)), and user plane entities that route packets or interconnections to external networks (e.g., serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function (UPF)). In some implementations, the control plane entities may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc.) of one or more UEs 104 served by one or more network entities 102 associated with the core network 106.

[0042] The core network 106 may communicate with the packet data network 108 via one or more backhaul links 116 (e.g., via S1, N2, N2, or another network interface). The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. The UE 104 may establish a session (e.g., a protocol data unit (PDU) session, etc.) with the core network 106 via the network entity 102. The core network 106 may use the established session (e.g., the established PDU session) to route traffic (e.g., control information, data, etc.) between the UE 104 and the application server 118. The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106).

[0043] In the wireless communication system 100, the network entity 102 and the UE 104 may use the resources of the wireless communication system 100 (e.g., time resources (e.g., symbols, time slots, subframes, frames, etc.) or frequency resources (e.g., subcarriers, carriers) to perform various operations (e.g., wireless communication). In some implementations, the network entity 102 and the UE 104 may support different resource structures. For example, the network entity 102 and the UE 104 may support different frame structures. In some implementations, such as in 4G, the network entity 102 and the UE 104 may support a single frame structure. In some other implementations, such as in 5G and other suitable radio access technologies, the network entity 102 and the UE 104 may support various frame structures (i.e., multiple frame structures). The network entity 102 and the UE 104 may support various frame structures based on one or more digital technologies.

[0044] One or more digital technologies may be supported in the wireless communication system 100, and the digital technologies may include subcarrier spacing and cyclic prefixes. A first digital technology (e.g., μ = 0) may be associated with a first subcarrier spacing (e.g., 15kHz) and a normal cyclic prefix. A first digital technology (e.g., μ = 0) associated with a first subcarrier spacing (e.g., 15kHz) may utilize one slot per subframe. A second digital technology (e.g., μ = 1) may be associated with a second subcarrier spacing (e.g., 30kHz) and a normal cyclic prefix. A third digital technology (e.g., μ = 2) may be associated with a third subcarrier spacing (e.g., 60kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth digital technology (e.g., μ = 3) may be associated with a fourth subcarrier spacing (e.g., 120kHz) and a normal cyclic prefix. A fifth digital technology (e.g., μ = 4) may be associated with a fifth subcarrier spacing (e.g., 240kHz) and a normal cyclic prefix.

[0045] The time intervals of resources (e.g., communication resources) can be organized according to frames (also referred to as radio frames). Each frame can have a duration, for example, a duration of 10 milliseconds (ms). In some implementations, each frame can include multiple subframes. For example, each frame can include 10 subframes, and each subframe can have a duration, for example, a duration of 1 ms. In some implementations, each frame can have the same duration. In some implementations, each subframe of a frame can have the same duration.

[0046] Additionally or alternatively, the time intervals of resources (e.g., communication resources) can be organized according to time slots. For example, a subframe may include a certain number (e.g., quantity) of time slots. Each time slot may include a certain number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of time slots of a subframe may depend on the digital technology. For a normal cyclic prefix, a time slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable to a 60kHz subcarrier spacing), a time slot may include 12 symbols. For a normal cyclic prefix and an extended cyclic prefix, the relationship between the number of symbols per time slot, the number of time slots per subframe, and the number of time slots per frame may depend on the digital technology. It should be understood that reference to a first digital technology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15kHz) may be used interchangeably between subframes and time slots.

[0047] In the wireless communication system 100, the electromagnetic (EM) spectrum can be divided into various categories, frequency bands, frequency channels, etc. based on frequency or wavelength. For example, the wireless communication system 100 can support one or more operating frequency bands, such as frequency range names FR1 (410 MHz-7.125 GHz), FR2 (24.25 GHz-52.6 GHz), FR3 (7.125 GHz-24.25 GHz), FR4 (52.6 GHz-114.25 GHz), FR4a or FR4-1 (52.6 GHz-71 GHz), and FR5 (114.25 GHz-300 GHz). In some implementations, the network entity 102 and the UE 104 can perform wireless communications on the one or more operating frequency bands. In some implementations, FR1 can be used by the network entity 102 and the UE 104 and other devices or apparatuses for cellular communication services (e.g., control information, data). In some implementations, FR2 can be used by the network entity 102 and the UE 104 and other devices or apparatuses for short-range, high data rate capabilities.

[0048] FR1 may be associated with one or more digital technologies (e.g., at least three digital technologies). For example, FR1 may be associated with a first digital technology (e.g., μ=0) including a subcarrier spacing of 15 kHz; a second digital technology (e.g., μ=1) including a subcarrier spacing of 30 kHz; a third digital technology (e.g., μ=2) including a subcarrier spacing of 60 kHz. FR2 may be associated with one or more digital technologies (e.g., at least 2 digital technologies). For example, FR2 may be associated with a third digital technology (e.g., μ=2) including a subcarrier spacing of 60 kHz; a fourth digital technology (e.g., μ=3) including a subcarrier spacing of 120 kHz.

[0049] As described throughout this disclosure, in accordance with implementation of subband-based full-duplex operation, the network entity 102 may send configuration information 120 to the UE 104, the configuration information including resources for full-duplex operation (e.g., full-duplex UL and DL operation by at least the network entity 102 and optionally by the UE 104). The configuration information 120 may also include interference measurement configurations, such as CLI resources for measuring CLI based at least in part on the resources provided for full-duplex operation. The UE 104 receives the configuration information 120 and uses the configuration information 120 to perform a configuration process 122 for configuring and performing full-duplex related operations (e.g., full-duplex DL and UL operations, UL transmissions on full-duplex UL subbands, or DL ​​receptions on full-duplex DL subbands) by the UE 104. In addition, the UE 104 performs interference measurements 124 (e.g., CLI measurements) using the interference configurations received as part of the configuration information 120. Using the full-duplex resources provided by the configuration information 120, the UE 104 performs an UL transmission 126 to the network entity 102. For example, as part of the UL transmission 126, the UE 104 sends an interference measurement 128 to the network entity 102 based on the interference measurement 124. In at least one implementation, the interference measurement 128 includes a CLI measurement measured on a CLI measurement resource provided by the configuration information 120.

[0050] In some wireless communication systems utilizing unpaired spectrum operation, when the DL BWP index and the UL BWP index are the same, a DL BWP from a configured DL BWP set (whose index is provided by the BWP-Id for the UE) may be linked with a UL BWP from a configured UL BWP set (whose index is provided by the BWP-Id for the UE). For unpaired spectrum operation, when the BWP-Id of the DLBWP is the same as the BWP-Id of the UL BWP, the UE may not expect to receive a configuration in which the center frequency of the DL BWP is different from the center frequency of the UL BWP.

[0051] In addition, for timeslot formation and configuration, if the UE is provided with tdd-UL-DL-ConfigurationDedicated, the parameter tdd-UL-DL-ConfigurationDedicated may override the flexible symbols per timeslot over a certain number of timeslots provided by tdd-UL-DL-ConfigurationCommon. tdd-UL-DL-ConfigurationDedicated provides:

[0052] - The slot configurations given by slotSpecificConfigurationsToAddModList

[0053] gather

[0054] -For each slot configuration in the slot configuration set

[0055] - The slot index of the slot provided by slotIndex

[0056] - the set of symbols for the time slot given by symbols, where

[0057] - If symbols = allDownlink, all symbols in the slot are downlink

[0058] road

[0059] If symbols = allUplink, all symbols in the slot are uplink.

[0060] - If symbols = explicit, then nrofDownlinkSymbols provides a certain number of downlink first symbols in a slot, and nrofUplinkSymbols provides a certain number of uplink last symbols in the slot. If nrofDownlinkSymbols is not provided, there is no downlink first symbol in the slot, and if nrofUplinkSymbols is not provided, there is no uplink last symbol in the slot. The remaining symbols in the slot are flexible.

[0061] In addition, if the UE is not configured to monitor DCI format 2_0 of the PDCCH, then for the symbol set indicated as a flexible slot by tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated (if provided), or when tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not provided to the UE:

[0062] - If the UE receives a corresponding indication via the DCI format, the UE shall

[0063] Receive PDSCH or CSI-RS in the set;

[0064] - If the UE receives a corresponding indication through a DCI format, a RAR UL grant, a fallback RAR UL grant or a successful RAR, the UE sends PUSCH, PUCCH, PRACH or SRS in the symbol set of the time slot.

[0065] For a symbol set of a time slot indicated to the UE as a flexible time slot by tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated (if provided), the UE may not expect to receive both dedicated higher layer parameters configuring transmissions from the UE in the symbol set of the time slot, and dedicated higher layer parameters configured in the symbol set of the time slot for reception by the UE.

[0066] In some wireless communication systems that implement CLI measurements, two types of CLI measurements have been specified, namely SRS reference signal received power (SRS-RSRP) and CLI reference signal strength indicator (CLI-RSSI). SRS-RSRP has been defined as the linear average (e.g., in watts) of the power contribution of resource elements carrying SRS. In addition, SRS-RSRP can be measured on resource elements configured within the configured measurement time opportunity and within the measurement frequency bandwidth considered. CLI-RSSI can be defined as the linear average (e.g., in watts) of the total received power observed in the configured OFDM symbols of (multiple) configured measurement time resources in the configured measurement bandwidth from all sources (such as including co-channel serving and non-serving cells, adjacent channel interference, thermal noise, etc.). For example, for FR1, the reference point for the measurement can be the antenna connector of the UE. For FR2, the measurement can be based on the combined signal from the antenna element corresponding to a given receiver branch. For FR1 and FR2, if the UE is using receiver diversity, the reported measurement value can have a lower limit defined by the corresponding measurement value of any individual receiver branch.

[0067] The SRS resources configured for SRS-RSRP measurement of the CLI in the DL BWP may include the same subcarrier spacing as the subcarrier spacing of the DL BWP. The UE may not be expected to measure SRS-RSRP using SRS-RSRP measurement resources that are not completely confined within the DL BWP. In addition, the UE may not be expected to measure more than 32 SRS resources, and the UE may not be expected to receive more than 8 SRS resources in a time slot.

[0068] To assist in handling interference such as self-interference and cross-link interference (e.g., UE to UE, base station (BS) to BS), subband-based full-duplex operation (i.e., one subband of a carrier serves UL traffic and another subband of the carrier serves DL traffic) may be implemented in unpaired spectrum. Accordingly, the present disclosure discusses configuring full-duplex UL and DL subbands for full-duplex operation in a cell, and measuring cross-link interference using subband-based full-duplex operation, such as when a serving network entity performs simultaneous reception and transmission in non-overlapping subbands within a carrier. For example, when a network entity (e.g., a gNB) is capable of simultaneous reception and transmission within a carrier (e.g., capable of full-duplex with a certain level of self-interference suppression), the network entity may configure a first subband of the carrier as an UL resource and a second subband of the carrier that does not overlap with the first subband as a DL resource for full-duplex cell operation within the carrier for at least a certain duration.

[0069] For example, for a subband configuration for full-duplex operation based on a subband, the UE receives information about time resources and frequency resources (e.g., full-duplex UL subbands) for UL transmission on symbols configured as DL and / or flexible symbols and / or time resources or frequency resources (e.g., full-duplex DL subbands) for DL ​​reception on symbols configured as UL or flexible symbols. The subband configuration may optionally include information about a guard band around the full-duplex subband. For example, the configuration of symbols as DL, UL, and / or flexible symbols is provided by tdd-UL-DL-ConfigurationCommon and additionally by tdd-UL-DL-ConfigurationDedicated (if configured). Information about full-duplex UL subbands and / or full-duplex DL subbands may be signaled in a system information block (SIB) and / or a dedicated RRC message as part of system information.

[0070] In at least one implementation, the information of the full-duplex UL subband and / or the full-duplex DL subband includes one or more of a frequency domain position, a time domain allocation, a subcarrier spacing, a cyclic prefix (CP) type, and an uplink configuration (such as PUSCH, PUCCH, RACH configuration, CG-PUSCH, etc.). In addition, the information of the full-duplex UL subband and / or the full-duplex DL subband may include an SRS configuration or a downlink configuration for the UL subband (such as PDSCH, PDCCH, and / or a semi-persistent scheduling (SPS) configuration for the DL subband). In at least one example, the UL and / or DL ​​configuration of the full-duplex UL and / or DL ​​subband may be provided by a BWP identifier, wherein the UE determines the UL and / or DL ​​configuration according to the configuration of the UL and / or DL ​​BWP indicated by the BWP identifier. The UE may assume that the subcarrier spacing and CP type of the full-duplex UL and / or DL ​​subbands are the same as those of the indicated UL and / or DL ​​BWP, such as when the subcarrier spacing or CP type is not configured separately for the full-duplex UL or DL ​​subbands.

[0071] Figure 2 An example FullDuplex-Subband-Config information element (IE) 200 supporting subband-based full-duplex operation according to aspects of the present disclosure is illustrated. For example, IE 200 may be used to configure a full-duplex UL and / or DL ​​subband (e.g., FullDuplex-Subband) list for a UE and / or in a cell. IE 200 includes different fields, some of which are detailed in Table 1:

[0072] Table 1

[0073]

[0074] In at least one implementation, according to a parameter startAndLengthIndicator indicating a start and length indicator value (SLIV), the number L of consecutive symbols counted from a start symbol S allocated for a full-duplex subband within a slot is determined as follows:

[0075] If (L-1)≤7, then

[0076] SLIV=14·(L-1)+S

[0077] otherwise

[0078] SLIV=14·(14-L+1)+(14-1-S)

[0079] Where 0<L≤14-S.

[0080] In at least one implementation, the virtual resource block (RBstart ) and the length L of the consecutively allocated resource blocks RBs The corresponding resource indication value (RIV) is defined as follows:

[0086] Figure 3 An example full-duplex UL subband configuration 300 supporting subband-based full-duplex operation according to aspects of the present disclosure is illustrated. For example, the network may configure the UL subband configuration 300 for the UE 104 using the IE 200. In this example, the UL subband configuration 300 is configured in 2 slots within every 5 slots, for example, a DL-UL mode with a period of 5 slots. The UL subband configuration 300 includes a BWP 302 and a BWP 304. Within the BWP 302, the UL subband configuration 300 includes a DL subband 306a, a DL subband 306b, a DL subband 306c, a DL subband 306d, a flexible subband 308a, and a UL subband 310a. Within the DL subband 306b, the UL subband configuration 300 is configured with a full-duplex UL subband 310b, and within the flexible subband 308a, the UL subband configuration 300 is configured with a full-duplex UL subband 310c. Within BWP 304, full-duplex UL subband configuration 300 includes DL subband 306d, DL subband 306e, DL subband 306f, flexible subband 308b, and UL subband 310d. In implementation, a UE may utilize UL subbands 310b, 310c as part of subband-based full-duplex operation.

[0087] The present disclosure also provides interference measurement for subband-based full-duplex operation, such as to implement an enhanced time domain CLI measurement configuration. For example, the UE receives a cross-link CLI measurement configuration included in a DL BWP configuration, wherein the CLI measurement configuration configures multiple measurement time instances or measurement opportunities (e.g., multiple measurement time slots) within a measurement period.

[0088] In at least one implementation, a plurality of CLI measurement slots configured within a measurement period have the same configuration of measurement symbols, such as a starting symbol and a number of symbols within the slot for measurement. Alternatively or additionally, each of the plurality of CLI measurement slots configured within the measurement period has a separate configuration of measurement symbols, such as a starting symbol and a number of symbols within the slot for measurement.

[0089] Figure 4 An example full-duplex UL subband configuration 400 supporting subband-based full-duplex operation according to aspects of the present disclosure is illustrated. In the UL subband configuration 400, a full-duplex UL subband 402 is configured within the bandwidth of an active DL BWP 404a of UE1 in cell 1 and a DL BWP 404b of UE3 in cell 2, wherein the active DL BW 404b of UE3 overlaps in frequency with the full-duplex UL subband 402, and can be configured to measure intra-subband UE-to-UE CLI 405 caused by UL transmissions in the full-duplex UL subband 402 in cell 1. For example, the full-duplex UL subband 402 can be configured on multiple time slots within a period of a DL-UL mode (e.g., provided by tdd-UL-DL-ConfigurationCommon) and can be used to perform CLI measurements on multiple time slots within a period of the DL-UL mode. This configuration allows for faster measurement and reporting, and therefore the time domain CLI measurement configuration can be enhanced to configure multiple measurement time slots within a measurement period.

[0090] In at least one implementation, the UE receives a full-duplex UL subband configuration including time domain allocation information for a cell, and also receives a CLI measurement configuration / indication without time domain information (e.g., period, slot offset, start symbol, and / or number of symbols within a slot) of CLI resources in the cell. The UE may perform CLI measurements on the CLI resources based on the time domain allocation of the full-duplex UL subband.

[0091] In at least one implementation, the RSSI-CLI resource in the time domain is determined according to a parameter startAndLengthIndicator (e.g., a start and length indicator value (SLIV)) for each full-duplex UL subband slot of the configured full-duplex UL subband. In the full-duplex UL subband configuration 400, since the full-duplex UL subband 402 is within the bandwidth of the active DL BWP 404a of UE1, and the active DL BWP 404c of UE2 is adjacent to the full-duplex UL subband 402 in cell 1, UE1 or UE2 can be configured to measure the inter-subband UE-to-UE CLI 406 caused by the UL transmission in the full-duplex UL subband 402. Similar to the intra-subband CLI measurement of CLI 405, UE1 or UE2 can be configured with multiple measurement slots within the measurement period, which can depend on the time domain configuration of the full-duplex UL subband 402 in cell 1. Alternatively or additionally, the CLI measurement configuration of UE1 or UE2 in cell 1 may not have a separate time domain configuration for CLI resources (e.g., RSSI resources or SRS resources) (or only include a partial time domain configuration, such as a measurement period), and may perform CLI measurements based on the time domain configuration information of the full-duplex UL subband, for example, by performing measurements on a time slot configured with the full-duplex UL subband 402.

[0092] In an implementation, a discontinuous CLI measurement bandwidth is provided. For example, the UE receives a configuration of a full-duplex UL subband 402, and when a CLI resource is configured in a cell having a CLI measurement bandwidth including at least one resource element of the full-duplex UL subband 402 of cell 1, the UE performs measurement on the CLI resource, excluding one or more resource elements of the CLI resource overlapping with the full-duplex UL subband 402.

[0093] Alternatively or additionally, the UE receives measurement bandwidth information of the CLI resource including multiple non-contiguous measurement bandwidths. In at least one implementation, each measurement bandwidth information includes a starting PRB and the number of consecutive PRBs. For example, in the full-duplex UL subband configuration 400, since the full-duplex UL subband 402 is within the bandwidth of the active DL BWP 404d of UE4, the two CLI measurement bandwidths of the CLI resource can be configured in a non-contiguous manner, so that the full-duplex UL subband 402 is excluded from the two CLI measurement bandwidths. Alternatively or additionally, one CLI measurement bandwidth is configured for the CLI resource, and the UE performs CLI measurement on resource elements of the CLI resource that do not overlap with the full-duplex UL subband 402.

[0094] Figure 5a and Figure 5b An example MeasObjectCLI IE 500 supporting subband-based full-duplex operation according to aspects of the present disclosure is illustrated. In at least some implementations, Figure 5a and Figure 5b Portions of IE 500 in may be combined into a single integrated IE, or may be transmitted via separate IEs. For example, IE 500 is adapted to specify information for SRS-RSRP measurements and / or CLI-RSSI measurements. In addition, IE 500 may be used to configure two measurement bandwidths, such as using parameters startPRB, nrofPRBs, startPRB2-r18, and nrofPRBs2-r18, and may be used to configure multiple measurement slots within a measurement period, such as via parameter RSSI-PeriodicityAndOffset-r18. IE 500 includes an SRS-ResourceConfigCLI portion (parameters described in Table 2a) that may be used to configure SRS resources to be used for CLI measurements, and an RSSI-ResourceConfig portion (parameters described in Table 2b) that may be used to configure CLI-RSSI resources to be used for CLI measurements.

[0104] In another example, according to examples disclosed herein, the processor 604 and / or the transceiver 608 may support wireless communications at the device 602. For example, the processor 604 and / or the transceiver 608 may be configured to or otherwise support components for: at a UE, receiving a semi-static DL and UL configuration; receiving information of a full-duplex UL subband, the full-duplex UL subband including time resources and frequency resources for UL transmission on symbols configured as one or more of DL symbols or flexible symbols based at least in part on the semi-static DL and UL configuration; and performing UL transmission on at least a portion of the full-duplex UL subband.

[0112] Figure 7 An example of a block diagram 700 of a device 702 (e.g., an apparatus) supporting subband-based full-duplex operation according to aspects of the present disclosure is illustrated. The device 702 may be an example of a network entity 102 as described herein.

The device 702 may include components for bidirectional communications, including components for sending and receiving communications (such as a processor 704, a memory 706, a transceiver 708, and an I / O controller 710). These components may be in electronic communication or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more interfaces (e.g., a bus).

[0114] In some implementations, the processor 704, the memory 706, the transceiver 708, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuit system). The hardware may include a processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, which is configured to or otherwise supports means for performing the functions described in the present disclosure.

[0115] For example, according to examples disclosed herein, the processor 704 and / or the transceiver 708 can support wireless communications at the device 702. For example, the processor 704 and / or the transceiver 708 can be configured to or otherwise support components for: sending a semi-static DL and UL configuration to a UE; sending information of a full-duplex UL subband to the UE, the full-duplex UL subband including time resources and frequency resources for UL transmission on symbols configured as one or more of DL symbols or flexible symbols based at least in part on the semi-static DL and UL configuration; and receiving interference measurements based on at least a portion of the information of the full-duplex UL subband from the UE.
