Description

Technical Field

[0001] All aspects of this disclosure relate to wireless communication in general, and to techniques and apparatus for reporting Time Domain Channel Attributes (TDCP). Background Technology

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. UEs may communicate with network nodes via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the network node to the UE, and "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via local links (e.g., sidelinks (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, etc.).

[0004] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by: improving spectrum efficiency; reducing costs; improving service; utilizing new spectrum; and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink; and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technologies and carrier aggregation. Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to increase. Summary of the Invention

Attached Figure Description

[0016] To gain a full understanding of the foregoing features of this disclosure, a more specific description of the invention, briefly outlined above, can be obtained by referring to various aspects, some of which are illustrated in the accompanying drawings. However, it should be noted that the drawings illustrate only certain typical aspects of this disclosure and are therefore not to be considered as limiting its scope, as the description may acknowledge other equally valid aspects. The same reference numerals in different drawings may identify the same or similar elements.

[0023] Figures 14 to 15 This is a diagram of an example device for wireless communication according to the present disclosure. Detailed Implementation

[0024] A periodic tracking reference signal (TRS) can be configured for user equipment (UE) loop tracking. This periodic TRS may not be associated with Time Domain Channel Attributes (TDCP) reporting. In addition to this periodic TRS, an incremental TRS can also be used. This incremental TRS can be dedicated to TDCP reporting. For example, the periodic TRS can be a first TRS, and the incremental TRS can be a second TRS. The second TRS can be associated with the first TRS on the same quasi-co-address. When the second TRS is not needed for UE loop tracking (e.g., the second TRS is redundant for UE loop tracking) and is dedicated only to TDCP reporting, allocating four Channel State Information Reference Signals (CSI-RS) resources to the second TRS may be unnecessary or redundant, and may result in unnecessarily high reference signal overhead.

[0025] In some aspects described herein, the UE may receive a TRS from a network node via a first set of CSI-RS resources. The UE may also receive CSI-RS from the network node via a second set of CSI-RS resources. The second set of CSI-RS resources may have fewer CSI-RS resources than the first set, for the delay between the first set and the second set of CSI-RS resources used for the TRS. The UE may send a TDCP report indicating time correlation calculations to the network node based at least in part on this delay between the first and second sets of CSI-RS resources used for the TRS. Since the second set of CSI-RS resources may be used only for the TDCP report and not for the TRS, the second set of CSI-RS resources may have fewer CSI-RS resources than the first set, thereby reducing reference signaling overhead. This reference signaling overhead can improve the performance of the UE and / or the network node.

[0026] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of protection of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods practiced using structures, functions, or structures and functions other than or different from the aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure herein may be embodied by one or more elements of the claims.

[0027] Various devices and techniques will now be used to illustrate several aspects of a telecommunications system. These devices and techniques will be described in detail below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively, “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 system as a whole.

[0028] Although terms generally associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used herein to describe aspects, aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or 5G and later (e.g., 6G) RATs.

[0029] Figure 1This 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., LTE) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. Network node 110 is a network node that communicates with UE 120. As shown, network node 110 may include one or more network nodes. For example, network node 110 can be an aggregated network node, meaning that the aggregated 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, network node 110 can be a decomposed network node (sometimes referred to as a decomposed base station), meaning that network node 110 is configured to utilize a protocol stack that is physically or logically distributed among 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)).

[0030] In some examples, network node 110 is or includes network nodes (such as RUs) that communicate with UE 120 via a radio access link. In some examples, network node 110 is or includes network nodes (such as DUs) that communicate with other network nodes 110 via a fronthaul or midhaul link. In some examples, network node 110 is or includes network nodes (such as CUs) that communicate with other network nodes 110 via a midhaul link or with the core network via a backhaul link. In some examples, network node 110 (such as aggregated network node 110 or 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. Network node 110 may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, Transmit / Receive Points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 can interconnect with each other or to one or more other network nodes 110 in the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks).

[0031] In some examples, network node 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), depending on the context in which the term is used, the term "cell" may refer to the coverage area of ​​network node 110 and / or the network node subsystem serving that coverage area. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A picocell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femtocell (e.g., UE 120 in a Closed Subscriber Group (CSG)). Network node 110 used for macrocells may be referred to as a macro network node. Network node 110 used for picocells may be referred to as a pico network node. The network node 110 used for femtocells can be referred to as a femtocell network node or a home network node. Figure 1 In the example shown, network node 110a can be a macro network node for macro cell 102a, network node 110b can be a pico network node for pico cell 102b, and network node 110c can be a femto network node for femto cell 102c. Network nodes can support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographical area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0032] 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, "base station" or "network node" may refer to a CU, DU, 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 multiple different devices (which may be located in the same geographical location or different geographical locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of that 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 can be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one base station function rather than another. In this way, a single device can include more than one base station.

[0033] Wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit data to downstream nodes (e.g., UE 120 or network node 110). A relay station may be a UE 120 that can relay transmissions to other UE 120s. Figure 1 In the example shown, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between network node 110a and UE 120d. The network node 110 for relay communication may be referred to as a relay station, relay base station, relay network node, relay node, relay, etc.

[0034] The wireless network 100 can be a heterogeneous network, comprising 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 effects on interference in the wireless network 100. For example, macro network nodes may have high transmit power levels (e.g., 5 watts to 40 watts), while pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 watts to 2 watts).

[0035] Network controller 130 may be coupled to or communicate with a group of network nodes 110, and may provide coordination and control for these network nodes 110. Network controller 130 may communicate with network nodes 110 via a backhaul or midhaul link. Network nodes 110 may also communicate directly with each other, or indirectly via a wireless or wired backhaul link. In some aspects, network controller 130 may be a CU or a core network device, or may include a CU or a core network device.

[0036] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, a UE function of a network node, and / or any other suitable device configured to communicate via wireless or wired media.

[0037] Some UEs 120 may be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with network nodes, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UEs 120 may be included within a housing that houses the components of the UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] Generally, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency in a given geographical area can support a single RAT to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0039] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary device to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0040] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been designated as frequency ranges FR1 (410MHz to 7.125GHz) and FR2 (24.25GHz to 52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, FR1 is often (interchangeably) referred to as the “sub-6GHz” band in various documents and articles. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although this is different from the Extremely High Frequency (EHF) band (30GHz to 300GHz) designated as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0041] The frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR studies have identified the operating bands used for these mid-band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0042] Considering the examples above, unless otherwise specified, it should be understood that if the term "below 6 GHz" is used herein, it can broadly refer to frequencies below 6 GHz, within FR1, or including intermediate frequency band frequencies. Furthermore, unless otherwise specified, it should be understood that if the term "millimeter wave" is used herein, it can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. Modifications to frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) are contemplated, and the techniques described herein are applicable to those modified frequency ranges.

[0043] In some aspects, the UE (e.g., UE 120) may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may: receive a TRS via a first set of CSI-RS resources; receive a CSI-RS via a second set of CSI-RS resources, wherein the second set of CSI-RS resources has fewer CSI-RS resources than the first set of CSI-RS resources for a delay between the first set of CSI-RS resources used for the TRS; and transmit a TDCP report indicating a time correlation calculation based at least in part on the delay between the first set of CSI-RS resources used for the TRS and the second set of CSI-RS resources. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0044] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may: transmit a TRS via a first set of CSI-RS resources; transmit a CSI-RS via a second set of CSI-RS resources, wherein the second set of CSI-RS resources has fewer CSI-RS resources than the first set of CSI-RS resources, for the delay between the first set of CSI-RS resources used for the TRS; and receive a TDCP report indicating a time correlation calculation, at least in part based on the delay between the first set of CSI-RS resources used for the TRS and the second set of CSI-RS resources. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0045] As indicated above, Figure 1 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 1 The content described is different.

[0046] Figure 2 This is a diagram illustrating example 200 of communication between network node 110 and UE 120 in a wireless network 100 according to the present disclosure. Network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). Network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and modems 232. In some examples, network node 110 may include an interface, communication components, or another component facilitating communication with UE 120 or another network node. Some network nodes 110 may not include radio frequency components facilitating direct communication with UE 120, such as one or more CUs or one or more DUs.

[0047] At network node 110, transmitting processor 220 can receive data from data source 212 intended for use by UE 120 (or a group of UEs 120). Transmitting processor 220 can select one or more modulation and decoding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. Network node 110 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling), and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., Cell-Specific Reference Signal (CRS) or Demodulation Reference Signal (DMRS)) and synchronization signals (e.g., Primary Synchronization Signal (PSS) or Secondary Synchronization Signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can also use a corresponding modulator component to process the output sample stream (e.g., convert to analog, amplify, filter, and / or up-convert) to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0048] At UE 120, a set of antennas 252 (shown as antennas 252a to 252r) can receive downlink signals from network node 110 and / or other network nodes 110 and can 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 can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on the received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, etc. In some examples, one or more components of UE 120 may be included in housing 284.

[0049] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, for example, in a core network. Network controller 130 may communicate with network node 110 via communication unit 294.

[0050] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more groups of antenna elements and / or one or more antenna arrays, etc., or may be included within one or more antenna panels, one or more antenna groups, one or more groups of antenna elements and / or one or more antenna arrays, etc. Antenna panels, antenna groups, groups of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), a group of coplanar antenna elements, a group of non-coplanar antenna elements and / or be coupled to one or more transmitting and / or receiving components (such as...). Figure 2 One or more antenna elements (one or more components in the process).

[0051] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 can be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to network node 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figures 5 to 15 ( ) aspects of any of the methods described in the method.

[0052] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., demodulator component of modem 232 (shown as DEMOD)), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of network node 110 may include modulator and demodulator. In some examples, network node 110 includes 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 this document (e.g., reference). Figures 5 to 15 ( ) aspects of any of the methods described in the method.

[0053] The controller / processor 240 of network node 110, the controller / processor 280 of UE 120 and / orFigure 2 Any other component may perform one or more techniques associated with TDCP reporting, as described in more detail elsewhere herein. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component that can execute or direct, for example Figure 12 Process 1200 Figure 13 The operation of process 1300 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, transformation and / or interpretation). Figure 12 Process 1200 Figure 13 The operation of process 1300 and / or other processes as described herein. In some examples, the execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, etc.

[0054] In some aspects, the UE (e.g., UE 120) includes: components for receiving a TRS via a first set of CSI-RS resources; components for receiving CSI-RS via a second set of CSI-RS resources, wherein the second set of CSI-RS resources has fewer CSI-RS resources than the first set of CSI-RS resources, for a delay between the first set of CSI-RS resources and the second set of CSI-RS resources used for the TRS; and / or components for transmitting a TDCP report indicating a time correlation calculation, at least in part based on the delay between the first set of CSI-RS resources and the second set of CSI-RS resources used for the TRS. Components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0055] In some aspects, a network node (e.g., network node 110) includes: components for transmitting a TRS via a first set of CSI-RS resources; components for transmitting CSI-RS via a second set of CSI-RS resources, wherein the second set of CSI-RS resources has fewer CSI-RS resources than the first set of CSI-RS resources, for the delay between the first set of CSI-RS resources and the second set of CSI-RS resources used for the TRS; and / or components for receiving a TDCP report indicating a time correlation calculation, at least in part based on the delay between the first set of CSI-RS resources and the second set of CSI-RS resources used for the TRS. Components for the network node to perform the operations described herein may include, for example, one or more of the following: a communication 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.

[0056] Although Figure 2 The boxes in the diagram are illustrated as different components, but the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0057] As indicated above, Figure 2 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 2 The content described is different.

[0058] The deployment of communication systems (such as 5G NR systems) can involve various components or parts arranged in multiple ways. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in a converged or decomposed architecture. For example, a base station (such as a Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell, etc.) or one or more units (or components) performing base station functionality can be implemented as a converged base station (also known as a standalone base station or a single base station) or a decomposed base station. A "network entity" or "network node" can 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 combinations thereof).

[0059] Aggregated base stations (e.g., aggregated network nodes) can 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 cell). Decomposed base stations (e.g., decomposed network nodes) can be configured to utilize a protocol stack that is physically or logically distributed across two or more cells (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. DUs may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual cell, such as a Virtual Central Unit (VCU), a Virtual Distributed Unit (VDU), or a Virtual Radio Unit (VRU), etc.

[0060] Base station type operation or network design can take into account the aggregation characteristics of base station functionality. For example, decomposed base stations can be utilized in IAB networks, Open Radio Access Networks (O-RAN (such as network configurations initiated by the O-RAN Alliance)), or Virtualized Radio Access Networks (vRAN, also known as Cloud Radio Access Networks (C-RAN)) to facilitate the scaling of communication systems by separating base station functionality into one or more units that can be deployed independently. Decomposed base stations can include functionality implemented by two or more units across various physical locations, as well as functionality virtually implemented for at least one unit, which enables flexibility in network design. The various units of a decomposed base station can be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0061] Figure 3 This is an illustration of an example disaggregated base station architecture 300 according to this disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more disaggregated control units (such as 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 a corresponding midhaul link (such as via an F1 interface). Each DU 330 may communicate with one or more RUs 340 via a corresponding fronthaul link. Each RU 340 may communicate with one or more UEs 120 via a corresponding radio frequency (RF) access link. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0062] Each unit in the clusters (including CU 310, DU 330, RU 340), as well as the near-RT RIC 325, non-RT RIC 315, and SMO frame 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via wired or wireless transmission media. Each unit in the cluster, or an associated processor or controller providing instructions to one or more communication interfaces of the respective unit, may be configured to communicate with one or more units in other clusters via transmission media. In some examples, each unit in the cluster may include a wired interface and a wireless interface configured to receive signals or transmit signals to one or more units in other clusters via a wired transmission media, and the wireless interface may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more units in other clusters via a wireless transmission media, or both.

[0063] In some aspects, the CU 310 can host one or more higher-level 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 can be implemented using an interface configured to signal to other control functions hosted by the CU 310. The CU 310 can be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP) functions), control plane functions (e.g., Central Unit-Control Plane (CU-CP) functions), or combinations thereof. In some implementations, the CU 310 can 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 units can communicate bidirectionally with the CU-CP units via an interface (such as an E1 interface). The CU 310 can be implemented to communicate with the DU 330 for network control and signaling purposes, as needed.

[0064] Each DU 330 may correspond to a logical unit comprising one or more base station functions for controlling the operation of one or more RU 340s. In some aspects, the DU 330 may host one or more of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to functional splits (such as those defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, and modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as those implemented 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 configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0065] Each RU 340 can implement low-level functionality. In some deployments, an RU 340 controlled by a DU 330 can correspond to a logical node that hosts RF processing functions or low-PHY layer functions, such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, based on function splitting (e.g., function splitting defined by 3GPP) (such as low-level function splitting). In this architecture, each RU 340 can be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, the real-time and non-real-time aspects of control plane and user plane communications with the RU 340 can be controlled by the corresponding DU 330. In some scenarios, this configuration allows each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as vRAN architecture).

[0066] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via operation and maintenance interfaces such as the O1 interface. For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the 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 the 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-RTTRIC 325. In some specific implementations, the SMO framework 305 can communicate with the hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0067] The non-RT RIC 315 can be configured to include logical functions that enable non-real-time control and optimization of RAN elements and resources, including artificial intelligence / machine learning (AI / ML) workflows for model training and updates, or policy-based guidance for applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or communicate with the near-RT RIC 325 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logical functions that enable near real-time control and optimization of RAN elements and resources via an interface (e.g., via an E2 interface) through data collection and action, connecting one or more CU 310s, one or more DU 330s, or both, and O-eNBs to the near-RT RIC 325.

[0068] In some implementations, to generate AI / ML models 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. This information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or network functions 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 in performance and employ AI / ML models to perform corrective actions via the SMO framework 305 (such as reconfiguration via the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0069] As indicated above, Figure 3 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 3 The content described is different.

[0070] Channel State Information (CSI) reports for high / medium UE speeds may be based at least in part on time-domain correlation and / or Doppler-domain information, which can assist in downlink pre-decoding in FR1. This CSI report may involve the UE's reporting of TDCP (TDCP report). TDCP can be measured via CSI-RS used for tracking.

[0071] UE reports on TDCP can be associated with various use cases, including codebook switching (e.g., Type I to Type II), channel sounding switching (e.g., CSI to Sounding Reference Signal (SRS)), or CSI / SRS periodicity, where DMRS temporal density can be excluded. UE reports on TDCP can indicate temporal correlation (or autocorrelation). Temporal correlation can be related to... The correlation is defined as follows: l and k represent time / frequency indices, respectively, and τ represents delay (lag). Latencies (lags) at the time slot level (e.g., τ = 5 or 10 time slots) may be relevant to the use case. It may be necessary to report time correlations associated with one or more delays (lags).

[0072] To assist network nodes in using TRS-based TDCP reports to determine codebook switching and SRS periodicity, quantized wideband normalized amplitude / phase of time-domain correlation curves with Y≥1 can be supported. This is especially useful when Y=1 and delay≤D. basic When there are only a few symbols, only the broadband quantization normalization magnitude can be reported. When Y = 1 and delay > D basicFor each symbol and when Y≥1, the wideband quantization normalized amplitude and phase of each delay can be reported. For Y>1, the phase can be configured to be non-existent for all delays in the Y delays. The value of Y can be configurable or can follow the delay from configured TRS resources. For TRS-based TDCP reporting, regarding the value of parameter Y when Y>1, the value of Y can be configured by the network node via higher-layer (e.g., RRC) signaling, the value of Y can follow the delay from configured TRS resources, or the value of Y can be selected and reported by the UE, wherein the value of Y can be at least partially based on UE capabilities.

[0073] Periodic TRS can support periodicities of 10 milliseconds (ms), 20 ms, 40 ms, or 80 ms, which may be too long for the latency (hysteresis) value of interest (e.g., 5 time slots). Shortening the TRS periodicity can increase overhead, so multiple TRS can be configured for TDCP reporting instead. The offset between two TRS can be the target latency (hysteresis) used for time correlation calculation. Multiple TRS used for TDCP reporting (e.g., all TRS) can be quasi-co-located (otherwise they cannot be used to derive time correlation). To save overhead, the second TRS can have a longer periodicity than the first TRS (e.g., an integer multiple of the first TRS periodicity) because TDCP may not need to be updated frequently. A TRS can be defined as a set of four single-port CSI-RS resources in two consecutive time slots, or a set of two single-port CSI-RS resources in a single time slot. The TRS can be configured using the TRS information (trs-Info) parameter. For example, the CSI-RS resource set can be configured via this TRS information parameter.

[0074] Figure 4 This is an illustration of example 400 of a plurality of TRSs for TDCP reporting according to this disclosure.

[0075] like Figure 4 As shown, multiple TRSs can be configured for TDCP reporting. A first TRS (TRS#1) periodicity (e.g., 10 ms) and a second TRS (TRS#2) periodicity (e.g., 40 ms) can be configured. The second TRS periodicity can be longer than the first TRS periodicity. The offset between the first and second TRSs can be a target delay (hysteresis) used for time correlation calculation. The first and second TRSs can be quasi-co-located to derive time correlation.

[0076] As indicated above, Figure 4 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 4 The content described is different.

[0077] A periodic TRS can be configured for UE loop tracking. This periodic TRS may not be associated with TDCP reporting. In addition to this periodic TRS, an incremental TRS can also be used. This incremental TRS can be dedicated to TDCP reporting. For example, the periodic TRS can be a first TRS, and the incremental TRS can be a second TRS. The second TRS can be associated with the first TRS on the same quasi-co-address. When the second TRS is not needed for UE loop tracking (e.g., the second TRS is redundant for UE loop tracking) and is dedicated only to TDCP reporting, allocating four CSI-RS resources to the second TRS may be redundant and may result in unnecessarily high reference signaling overhead.

[0078] In various aspects of the technologies and apparatus described herein, the UE can receive a TRS from a network node via a first set of CSI-RS resources. The UE can also receive CSI-RS from the network node via a second set of CSI-RS resources. The second set of CSI-RS resources may have fewer CSI-RS resources than the first set, for the delay between the first set and the second set of CSI-RS resources used for the TRS. The UE can send a TDCP report indicating time correlation calculation to the network node based at least in part on the delay between the first and second sets of CSI-RS resources used for the TRS. Since the second set of CSI-RS resources can be used only for the TDCP report and not for the TRS, the second set of CSI-RS resources may have fewer CSI-RS resources than the first set, thereby reducing reference signaling overhead. This reference signaling overhead can improve the performance of the UE and / or the network node.

[0079] Figure 5 This is an illustration of Example 500 associated with a TDCP report according to this disclosure. (See diagram below.) Figure 5 As shown, Example 500 includes communication between a UE (e.g., UE 120) and a network node (e.g., network node 110). In some aspects, the UE and the network node may be included in a wireless network (such as wireless network 100).

[0080] As shown by reference numeral 502 in the attached figure, the UE can receive a TRS from the network node via a first set of CSI-RS resources. The TRS can be a periodic TRS, or alternatively, it can be an aperiodic TRS. A subset of resources in the first set of CSI-RS resources used for the TRS can be associated with a TDCP report, and this subset of resources in the first set of CSI-RS resources used for the TRS can be based at least in part on latency.

[0081] As shown by reference numeral 504 in the attached figure, the UE can receive CSI-RS from the network node via a second set of CSI-RS resources. The CSI-RS can be periodic CSI-RS, or alternatively, it can be aperiodic CSI-RS. The second set of CSI-RS resources may have fewer CSI-RS resources than the first set for delays between the first set and the second set of CSI-RS resources used for the TRS. The second set of CSI-RS resources may be associated with one delay. The second set of CSI-RS resources may be associated with more than one delay. Each delay may be associated with a set of CSI-RS resources within the second set of CSI-RS resources, and this set of CSI-RS resources may have one or two CSI-RS resources. In some cases, multiple delays may be configured for the TDCP reporting, and each of these multiple delays may be associated with the same subset of resources in the first set of CSI-RS resources used for the TRS.

[0082] In some respects, for a list (superset) of more than one set of CSI-RS resources configured for the TDCP reporting, the first set may be configured as the TRS. The first set may have a certain number of CSI-RS resources within the TRS (e.g., two or four CSI-RS resources). Compared to the first set, other sets (e.g., the second set) may have a smaller number of CSI-RS resources per delay (hysteresis).

[0083] In some aspects, in the first option, each set of other sets of CSI-RS resources may be associated with a delay (hysteresis). This first option is applicable to periodic TRS and CSI-RS cases. Periodicity and offset can be configured per resource. The first option is also applicable to aperiodic TRS and CSI-RS cases. Aperiodicity triggering offset can be configured per resource set. For this periodic TRS and CSI-RS case, the periodicity of each CSI-RS resource may be the same for resource sets other than the first set (TRS), which may result in measurements of delays (e.g., delay A and delay B) being taken as frequently as possible (e.g., measuring both delays equally frequently). Furthermore, for this first option, the smaller number of CSI-RS resources in the other sets (e.g., one or two CSI-RS resources) may be less than the certain number of CSI-RS resources in the first set (e.g., two or four CSI-RS resources).

[0084] In some aspects, in the second option, multiple CSI-RS resources (e.g., all CSI-RS resources) other than the certain number of CSI-RS in the first set (TRS) can be configured in the second set, and these multiple CSI-RS resources can be associated with one or more delays (hysteresis). This second option may be applicable only to the periodic TRS and CSI-RS case, where periodicity and offset are configured per resource, and existing standards may have already guaranteed that the periodicity is the same within the same resource set (e.g., the second set). Furthermore, for this second option, each delay (hysteresis) can be associated with one (or two) CSI-RS resources within the second set.

[0085] Regarding the first option and the second option, Figure 6 The example shown is one symbol per delay (lag). For both the first and second options, Figure 7 The example shown is two symbols per delay (lag). For one symbol per delay (lag), Figure 9 Examples of periodic TRS and CSI-RS cases are shown, as well as examples of aperiodic TRS and CSI-RS cases. For each delay (hysteresis) of two symbols, Figure 10 Examples of periodic TRS and CSI-RS cases are shown in the figure, as well as examples of non-periodic TRS and CSI-RS cases.

[0086] In some aspects, the UE can receive Channel State Information (CSI) report configuration indicating the delay value from the network node as part of the CSI measurement configuration. In some aspects, the delay (hysteresis) value can be explicitly configured using the CSI-reportConfig parameter. For example, the delay (hysteresis) value can be 5 or 10 time slots, or 5 ms or 10 ms. Because the delay (hysteresis) value can be directly derived from the periodicity and offset, but due to the ambiguity between the following two values: one value equals the first offset minus the second offset (e.g., offset1 - offset2), and the other value equals the periodicity minus the difference between the first and second offsets (e.g., periodicity - (offset1 - offset2)), the delay (hysteresis) value can be explicitly configured. For CSI-RS resource sets other than this first set, the TRS information (trs-info) parameter may not be configured. Figure 8 An example of CSI reporting configuration is shown in the figure.

[0087] In some respects, delays (hysteresis) can be associated with CSI-RS resource pairs rather than resource set pairs. A subset of one or two resources (e.g., only one or two resources) in the first set (TRS) can be associated with the TDCP report. The resources in the first set associated with the TDCP report can be implicitly determined by the configured delays (hysteresis). When Y>1 delays (hysteresis) are configured for the TDCP report, multiple delays (hysteresis) (e.g., all delays or hysteresis) can be associated with the same one or two resources in the first set. Therefore, the UE may only need to buffer the demodulation of one or two TRS symbols (e.g., one or two CSI-RS resources within the first resource set, rather than all four CSI-RS resources within the first resource set) to calculate the time correlation (e.g., TDCP) with the upcoming CSI-RS resources (e.g., the second resource set).

[0088] like Figure 5 As indicated by reference numeral 506 in the accompanying drawings, the UE can send a TDCP report indicating time correlation calculation to the network node based at least in part on the delay between the first set of CSI-RS resources and the second set of CSI-RS resources used for the TRS. The UE can perform measurements associated with the first set and the second set of CSI-RS resources, and based at least in part on these measurements, the UE can perform time correlation calculation. The UE can indicate the time correlation calculation in the TDCP report sent to the network node.

[0089] In some aspects, after CSI report configuration or reconfiguration, serving cell activation, bandwidth portion (BWP) change, or semi-persistent CSI (SP-CSI) activation, the UE may report a CSI report only after receiving at least one CSI-RS transmission opportunity for channel measurements and a CSI-RS and / or CSI interference management (CSI-IM) opportunity for interference measurements no later than the CSI reference resources; otherwise, the UE may discard the CSI report. When discontinuous reception (DRX) is configured, the UE may report a CSI report only after receiving at least one CSI-RS transmission opportunity for channel measurements and a CSI-RS and / or CSI-IM opportunity for interference measurements during the DRX active time no later than the CSI reference resources; otherwise, the UE may discard the CSI report.

[0090] In some respects, this CSI reference resource can be defined for verification tests (e.g., a target block error rate (BLER) of 10%) with reported Channel Quality Indicators (CQI) (and Pre-decoding Matrix Indicators (PMI), if also reported). This CSI reference resource can be associated with frequency resources. These frequency resources can be identical to the CSI-RS measured in the frequency domain. This CSI reference resource can also be associated with time resources. These time resources can be associated with the effective downlink time slot nn. CSI_ref (Before the uplink slot n in which CSI is reported) associated. For periodic or semi-persistent reporting, n CSI_ref It can be ≥ (Single CSI-RS) or ≥ The minimum value of (multiple CSI-RS) makes the time slot nn CSI_ref Corresponding to the effective downlink time slot. For non-periodic reports, n CSI_ref It can be ≥ The minimum value of makes the time slot nn CSI_ref This corresponds to the effective downlink time slot (where Z′ (in symbols) is the processing timeline required from CSI-RS to the Physical Uplink Shared Channel (PUSCH) used for reporting). In other words, for CSI reference resource time slot n ref and reporting time slot n, n ref For periodic or semi-persistent reporting, ≥4 or 5 time slots, or for non-periodic reporting, ≥ The assumed Physical Downlink Shared Channel (PDSCH) mode may include the symbols used within the time slot, the DMRS mode, the subcarrier spacing (SCS), and / or the layer mapping mode associated with the reported PMI.

[0091] In some aspects, the UE may transmit the TDCP report at least in part based on receiving at least one pair of CSI-RS resources associated with the delay no later than a certain number of symbols before the PUSCH used to transmit the TDCP report associated with the delay (regardless of whether a CSI reference resource (time slot) for the TDCP report is defined). In some aspects, when DRX is configured, the UE may transmit the TDCP report at least in part based on receiving at least one pair of CSI-RS resources associated with the delay during the DRX activity time no later than a certain number of symbols before the PUSCH used to transmit the TDCP report associated with the delay.

[0092] In some respects, after TDCP report configuration or reconfiguration, serving cell activation, BWP change, or SP-CSI (TDCP) activation, the UE may send a TDCP report associated with the delay (hysteresis) only after receiving at least one pair of (single-port) CSI-RS resources associated with the delay (hysteresis) no later than Z' symbols before PUSCH. Otherwise, the UE may discard the TDCP report (without update), or the UE may report an invalid TDCP value (e.g., zero time correlation). The Z' symbols may be associated with a TDCP timeline (which may reuse existing Z1', Z2', or Z3' symbols) or with a new timeline. The delay (hysteresis) may be associated with resource pairs from the first set (TRS) and the second set (e.g., set #>1).

[0093] In some respects, when DRX is configured, the UE may send a TDCP report associated with the delay (hysteresis) only after receiving at least one pair of (single-port) CSI-RS resources associated with the delay (hysteresis) during the DRX active time, no later than Z' symbols before PUSCH. Otherwise, the UE may discard the TDCP report (without update) or report an invalid TDCP value (e.g., zero time correlation). The Z' symbols may be associated with a TDCP timeline (which may reuse existing Z1', Z2', or Z3' symbols) or with a new timeline. The delay (hysteresis) may be associated with resource pairs from the first set (TRS) and the second set (e.g., set #>1).

[0094] In some respects, when the TDCP report is at least partially based on aperiodic reference signals (e.g., TRS and CSI-RS), the measured CSI-RS resources (e.g., all measured CSI-RS resources) may lie between the Physical Downlink Control Channel (PDCCH) and the PUSCH used for reporting. The delay (hysteresis) between the two (single-port) CSI-RS resources can be relatively large (e.g., ten time slots), plus the timeline (e.g., Z' symbols). Therefore, the PDCCH to PUSCH time slot offset (K2) may also need to be relatively large.

[0095] In some aspects, the UE may receive from the network node a first-phase PDCCH that triggers the second set of TRS, CSI-RS resources, and TDCP-related measurements. The UE may receive from the network node a second-phase PDCCH that triggers the TDCP report via a PUSCH. The same triggering state may be associated with the first PDCCH and the second-phase PDCCH, and the second PDCCH or the PUSCH may be located within a timer following the last CSI-RS resource associated with the TDCP report.

[0096] In some respects, for PUSCH scheduling associated with PDCCH-PUSCH slot offset (K2) and aperiodic reference signals (e.g., TRS and CSI-RS), a two-stage PDCCH can be used to trigger aperiodic reporting at least in part based on the aperiodic reference signal. The first-stage PDCCH (PDCCH1) can trigger aperiodic reference signals and TDCP-related measurements. The second-stage PDCCH (PDCCH2) can trigger aperiodic reporting via the scheduled PUSCH. The association between the first-stage PDCCH and the second-stage PDCCH can be the same triggering state in the downlink control information (DCI) of both PDCCHs. Furthermore, for this association, the second-stage PDCCH or the scheduled PUSCH (for aperiodic reporting) can be located within a timer following the last CSI-RS resource (or CSI reference resource) associated with the TDCP reporting.

[0097] As indicated above, Figure 5 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 5 The content described is different.

[0098] Figure 6 This is an illustration of Example 600 associated with a TDCP report according to this disclosure.

[0099] As shown by reference numeral 602 in the attached figure, in the first option, with one symbol of delay (hysteresis), the first set (set #1) (TRS) may be associated with four non-zero power (NZP) CSI-RS resources. Compared to the first set, the second set (set #2) may have fewer NZP CSI-RS resources (e.g., one NZP CSI-RS resource). This second set may be associated with a first delay (e.g., delay A). Compared to the first set, the third set (set #3) may have fewer NZP CSI-RS resources (e.g., one NZP CSI-RS resource). This third set may be associated with a second delay (e.g., delay B). In other words, the other sets of CSI-RS resources may each be associated with one delay (hysteresis).

[0100] As shown by reference numeral 604 in the attached figure, in the second option, the first set (set #1) (TRS) can be associated with four NZP CSI-RS resources for each delay (hysteresis) of one symbol. The second set (set #2) can have fewer NZP CSI-RS resources (e.g., two NZP CSI-RS resources) compared to the first set. This second set can be associated with a first delay (e.g., delay A) and a second delay (e.g., delay B). In other words, CSI-RS resources other than those in the first set can be configured in this second set, and the CSI-RS resources in this second set can be associated with one or more delays (hysteresis).

[0101] As indicated above, Figure 6 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 6 The content described is different.

[0102] Figure 7 This is an illustration of Example 700 associated with a TDCP report according to this disclosure.

[0103] As shown by reference numeral 702 in the attached figure, in the first option, with two symbols per delay (lag), the first set (set #1) (TRS) may be associated with four NZP CSI-RS resources. Compared to the first set, the second set (set #2) may have fewer NZP CSI-RS resources (e.g., two NZP CSI-RS resources). The NZP CSI-RS resources in this second set may be associated with a first delay (e.g., delay A). Compared to the first set, the third set (set #3) may have fewer NZP CSI-RS resources (e.g., one NZP CSI-RS resource). The NZP CSI-RS resources in this third set may be associated with a second delay (e.g., delay B). In other words, the other sets of CSI-RS resources may each be associated with one delay (lag).

[0104] As shown by reference numeral 704, in the second option, with two symbols per delay (hysteresis), the first set (set #1) (TRS) can be associated with four NZP CSI-RS resources. The second set can include a first group of NZP CSI-RS resources, which can be associated with a first delay (e.g., delay A). The second set can also include a second group of NZP CSI-RS resources, which can be associated with a second delay (e.g., delay B). In other words, CSI-RS resources other than those in the first set can be configured in the second set, and the CSI-RS resources in the second set can be associated with one or more delays (hysteresis).

[0105] As indicated above, Figure 7 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 7 The content described is different.

[0106] Figure 8 This is an illustration of Example 800 associated with a TDCP report according to this disclosure.

[0107] like Figure 8 As shown, the CSI Measurement Configuration (CSI-MeasConfig) can indicate the CSI Aperiodic Trigger State List (CSI-AperiodicTriggerStateList). This CSI Aperiodic Trigger State List can indicate the CSI Report Configuration (CSI-ReportConfig), which can indicate the reporting quantity. The reporting quantity can indicate a list of TDCP delay values ​​(e.g., delay A, delay B, etc.). This TDCP delay value list can indicate delay (hysteresis) values. The CSI Report Configuration can indicate the CSI Resource Configuration (ResourceConfig), which can indicate the resource type (e.g., periodic or aperiodic). The CSI Resource Configuration can indicate the NZP CSI-RS Resource Set (NZP-CSI-RS-ResourceSet) (e.g., a first set (TRS) and a second set). The NZP CSI-RS Resource Set can indicate aperiodic trigger offsets and / or TRS information. The NZPCSI-RS resource set can indicate NZP CSI-RS resources (NZP-CSI-RS-Resource), which can indicate periodicity and offset.

[0108] As indicated above, Figure 8 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 8 The content described is different.

[0109] Figure 9 This is an illustration of Example 900 associated with a TDCP report according to this disclosure.

[0110] As shown by reference numeral 902 in the attached figure, in the case of periodic TRS and CSI-RS, with a delay (lag) of one symbol, the periodicity of TRS (TRS#1) can be configured (e.g., 10 ms), the periodicity of the first CSI-RS (CSI-RS#A) (e.g., 40 ms), and the periodicity of the second CSI-RS (CSI-RS#B) (e.g., 40 ms). The second CSI-RS periodicity can be the same as the first CSI-RS periodicity. The first delay can be associated with the start of the TRS periodicity and the start of the first CSI-RS periodicity. The second delay can be associated with the start of the TRS periodicity and the start of the second CSI-RS periodicity.

[0111] As shown by reference numeral 904 in the attached figure, in the case of aperiodic TRS and CSI-RS, a network node can send a PDCCH with a delay (lag) of one symbol and a trigger offset for the aperiodic TRS (set #1). The trigger offsets for the aperiodic set (set #2) and the aperiodic set (set #3) are configurable. A first delay may begin from the resource associated with the TDCP report in the aperiodic TRS (set #1) and may end at the end of the trigger offset of the aperiodic set (set #2). A second delay may begin from the resource associated with the TDCP report in the aperiodic TRS (set #1) and may end at the end of the trigger offset of the aperiodic set (set #2). The trigger offset of the aperiodic TRS (set #1) can be associated with the PDCCH and the resource associated with the TDCP report in the aperiodic TRS (set #1).

[0112] As indicated above, Figure 9 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 9 The content described is different.

[0113] Figure 10 This is an illustration of Example 1000 associated with a TDCP report according to this disclosure.

[0114] As shown by reference numeral 1002 in the attached figure, in the case of periodic TRS and CSI-RS, with a delay (lag) of two symbols, the periodicity of TRS (TRS#1) (e.g., 10 ms), the periodicity of the first CSI-RS (CSI-RS#A) (e.g., 40 ms), and the periodicity of the second CSI-RS (CSI-RS#B) (e.g., 40 ms) can be configured. The second CSI-RS periodicity can be the same as the first CSI-RS periodicity. The first delay can be associated with the start of the TRS periodicity and the start of the first CSI-RS periodicity. The second delay can be associated with the start of the TRS periodicity and the start of the second CSI-RS periodicity.

[0115] As shown in Figure 1004, in the cases of aperiodic TRS and CSI-RS, a network node can send a PDCCH with a delay (lag) of two symbols per cycle. The trigger offsets for aperiodic TRS (set #1), aperiodic set (set #2), and aperiodic set (set #3) are configurable. A first delay may begin from the resource associated with the TDCP report in the aperiodic TRS (set #1) and may end at the end of the trigger offset of the aperiodic set (set #2). A second delay may begin from the resource associated with the TDCP report in the aperiodic TRS (set #1) and may end at the end of the trigger offset of the aperiodic set (set #2). The trigger offset of the aperiodic TRS (set #1) can be associated with the PDCCH and the resource associated with the TDCP report in the aperiodic TRS (set #1).

[0116] As indicated above, Figure 10 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 10 The content described is different.

[0117] Figure 11 This is an illustration of Example 1100 associated with a TDCP report according to this disclosure.

[0118] like Figure 11 As shown, a network node can send a first PDCCH that can trigger an aperiodic reference signal and TDCP-related measurements. Trigger offsets for aperiodic TRS (set #1), aperiodic sets (set #2), and aperiodic sets (set #3) are configurable. A first delay can begin from the resource associated with TDCP reporting in the aperiodic TRS (set #1) and end at the end of the trigger offset in the aperiodic set (set #2). A second delay can begin from the resource associated with TDCP reporting in the aperiodic TRS (set #1) and end at the end of the trigger offset in the aperiodic set (set #2). A network node can send a second PDCCH that can trigger an aperiodic report via a PUSCH. The first and second PDCCHs can be associated with the same trigger state (or the same DCI). The second PDCCH or the PUSCH may be located within a threshold timer following the last CSI-RS resource associated with the TDCP report.

[0119] As indicated above, Figure 11 This is provided as an example. Other examples are available with reference to [the relevant information]. Figure 11 The content described is different.

[0120] Figure 12 This is a diagram illustrating an example procedure 1200 performed by a UE according to this disclosure. Example procedure 1200 is an example in which a UE (e.g., UE 120) performs an operation associated with a TDCP report.

[0121] like Figure 12 As shown, in some aspects, process 1200 may include: receiving a TRS via a first set of CSI-RS resources (block 1210). For example, the UE (e.g., using...) Figure 14 The receiving component 1402 and / or communication manager 1406 depicted herein can receive TRS via a first set of CSI-RS resources, as described above.

[0122] like Figure 12 Further shown, in some aspects, process 1200 may include: receiving CSI-RS via a second set of CSI-RS resources, wherein the second set of CSI-RS resources has fewer CSI-RS resources than the first set of CSI-RS resources for the delay between the first set of CSI-RS resources used for the TRS (box 1220). For example, the UE (e.g., using...) Figure 14 The receiving component 1402 and / or communication manager 1406 described herein can receive CSI-RS via a second set of CSI-RS resources, wherein the second set of CSI-RS resources has fewer CSI-RS resources than the first set of CSI-RS resources, for the delay between the first set of CSI-RS resources used for the TRS.

[0123] like Figure 12 Further, in some aspects, process 1200 may include: transmitting a TDCP report indicating time correlation calculation (box 1230) based at least in part on the delay between the first set of CSI-RS resources used for the TRS and the second set of CSI-RS resources. For example, the UE (e.g., using...) Figure 14 The transmitting component 1404 and / or the communication manager 1406 described herein may transmit a TDCP report indicating time correlation calculation, as described above, based at least in part on the delay between the first set of CSI-RS resources for the TRS and the second set of CSI-RS resources.

[0132] In the eighth aspect, either alone or in combination with one or more of the first to seventh aspects, multiple delays are configured for the TDCP report, and each of the multiple delays is associated with the same subset of resources in the first set of CSI-RS resources for the TRS.

[0133] In the ninth aspect, alone or in combination with one or more of the first to eighth aspects, process 1200 includes: transmitting the TDCP report based at least in part on receiving at least one pair of CSI-RS resources associated with the delay no later than a certain number of symbols before the PUSCH used to transmit the TDCP report associated with the delay.

[0134] In the tenth aspect, DRX is configured alone or in combination with one or more of the first to ninth aspects, and process 1200 includes: sending the TDCP report based at least in part on receiving at least one pair of CSI-RS resources associated with the delay during the DRX active time no later than a certain number of symbols before the PUSCH used to send the TDCP report associated with the delay.

[0137] although Figure 12 An example box of process 1200 is shown, but in some respects, process 1200 may include... Figure 12 The boxes depicted may be fewer, different, or arranged differently compared to additional boxes. Alternatively, two or more boxes in process 1200 may be executed in parallel.

[0138] Figure 13 This is a diagram illustrating, for example, an example process 1300 performed by a network node according to this disclosure. Example process 1300 is an example in which a network node (e.g., network node 110) performs operations associated with a TDCP report.

[0139] like Figure 13 As shown, in some aspects, process 1300 may include: sending a TRS (box 1310) via a first set of CSI-RS resources. For example, the network node (e.g., using...) Figure 15 The transmitting component 1504 and / or communication manager 1506 described herein can transmit TRS via a first set of CSI-RS resources, as described above.

For example, the network node (e.g., using...)

[0156] Figure 14 This is a diagram of an example device 1400 for wireless communication according to the present disclosure. Device 1400 may be a UE, or a UE may include device 1400. In some aspects, device 1400 includes a receiving component 1402, a transmitting component 1404, and / or a communication manager 1406 that can communicate with each other (e.g., via one or more buses and / or one or more other components). In some aspects, communication manager 1406 is combined with... Figure 1 The described communication manager 140. As shown, device 1400 can communicate with another device 1408, such as a UE or a network node (such as a CU, DU, RU or base station), using receiving component 1402 and transmitting component 1404.
