[0018] The electronic device according to one embodiment can be one of various types of electronic devices. For example, the electronic device can include a portable communication device (e.g., a smartphone), a computer, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance.

It is intended that if an element (e.g., a first element) is referred to as being "coupled to" or "connected to" another element (e.g., a second element) without using the term "directly" or "communicatively," it means that the element can be coupled to the other element directly (e.g., wiredly), wirelessly, or via a third element.

[0020] As used herein, the term "module" can include a unit implemented in hardware, software, or firmware, and can interchangeably be used with other terms, for example, "logic", "logic block", "component", and "circuitry". A module can be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, a module can be implemented in a form of an application-specific integrated circuit (ASIC).

[0021] Channel access procedures are referred to as Listen-Before-Talk (LBT). Devices employing LBT can be classified as Load-Based Equipment (LBE) or Frame-Based Equipment (FBE). For LBE, channel sounding can occur at any instance of data transmission, but a random back-off procedure is applied when the channel is found to be busy. For FBE, a predetermined periodic channel access opportunity is applied, and a fixed duration for data transmission and a subsequent fixed idle period are associated with each channel sounding. If the channel sounding procedure is successful in FBE, the disclosed fixed duration for data transmission can be utilized. Otherwise, access to the channel is not allowed until the next channel access opportunity.

[0022] According to LBT, DL transmission cannot be guaranteed due to unpredictable channel access procedure outcomes in the network. In particular, the available bandwidth for DL transmission can vary at each channel access procedure, and the DL transmission power can vary accordingly. Therefore, it is reasonable for a UE to determine the DL transmission with different transmission powers according to different channel occupancy durations acquired at different network channel access procedures, and the UE should confirm this aspect in the related operation. However, channel occupancy duration information can not always be known by the UE. One identified operation affected by the lack of channel occupancy duration information is the procedure of the UE utilizing CSI-RS power. In licensed spectrum, the UE can measure CSI-RS power at several reception occasions to improve the estimation of channel noise. Due to unpredictable channel access status in unlicensed spectrum, this operation is not easily performed without considering the potentially varying transmission power at each reception occasion. One approach to solve this problem is to determine that the CSI-RS transmission power is different at each occasion. However, such a determination is overly conservative and will sacrifice channel noise estimation performance.

[0023] Figure 1 A diagram showing CSI-RS occasions occurring within a COT is shown. To address the potential CSI-RS power variation issue, the UE can utilize the received power of CSI-RS with available information about the COT (or channel occupancy duration). One useful information is the COT indicated in DCI format 2_0. As Figure 1As shown, according to the DCI 102, the UE can determine the COT 104, and within the COT 104, the UE can determine the CSI-RS occasions 106, 108, and 110. The UE can determine that the CSI-RS occasions 106, 108, and 110 have the same power. Figure 1 In the example shown, the CSI-RS occasions 106, 108, and 110 occur within the COT. With the channel occupancy duration information, the UE can know the duration of the channel occupancy acquired by the network and determine that the CSI-RS occasions within the indicated channel occupancy duration have the same power.

[0024] Figure 2A and Figure 2B A diagram illustrating CSI-RS occasions occurring in DL transmissions according to an embodiment is shown. In Figure 2A In the example shown, the CSI-RS occasions 202 and 204 are within the two DL transmissions 206 and 208. In Figure 2B In the example shown, the CSI-RS occasion 210 occurs before the first DL transmission 212, and the CSI-RS occasion 214 occurs after the second DL transmission 216. The UE can also determine that the set of DL transmissions with small gaps (e.g., approximately 16 μβ) are transmitted within the same channel occupancy from the network. Thus, the UE can determine that the CSI-RS occasions that are part of the set of DL transmissions with small gaps have the same power.

[0025] When the COT information is not available at the UE, the UE can utilize a timer to specify the duration of the channel potentially occupied by the network. With the timer, the UE can determine that the CSI-RS occasions occurring within the duration of the running timer have the same transmission power. One example of the timer can be the timer introduced for the group of switching search space sets.

[0026] Figure 3A and Figure 3B A diagram illustrating CSI-RS occasions occurring between DCI and PDSCH according to an embodiment is shown. After a successful channel access procedure, the network can include DL transmissions to multiple UEs in one COT. In this case, the DL transmissions received at each UE can have large gaps even within a single channel occupancy duration. To solve the CSI-RS power determination in this case, the UE can determine that the dynamic DCI and the data scheduled in the PDSCH are within the same COT. Thus, if a set of DL transmissions satisfies certain timing conditions (e.g., all detected DCIs within the set of DL transmissions are received between the detected DCI and the PDSCH scheduled by the detected DCI), the CSI-RS occasions that are part of the set of DL transmissions can be determined to have the same power. As Figure 3AAs shown, CSI-RS occasions 302 and 304 occur between DCI 306 and PDSCH 308. Thus, the UE determines that CSI-RS occasions 302 and 304 have the same power. In Figure 3B In the middle, CSI-RS occasion 310 occurs between first DCI 316 and first PDSCH 320. CSI-RS occasion 312 occurs between second DCI 318 and first PDSCH 320. CSI-RS occasion 314 occurs between second DCI 318 and second PDSCH 322. Thus, the UE determines that CSI-RS occasions 310, 312, and 314 have the same power.

[0027] For FBE, due to the nature of the associated channel access procedure, each data transmission duration can be considered as a COT when the associated channel sounding is successful before the data transmission duration. Thus, the UE can determine that CSI-RS occasions occurring within the same transmission duration have the same power. In particular, if for each PDCCH in a group of physical downlink control channels (PDCCHs) except the most recently received PDCCH, there exists such a second PDCCH in the group that satisfies the second PDCCH’s ending symbol is later than or equal to (or not earlier than more than 16 us) the first PDCCH’s starting symbol and the second PDCCH’s starting symbol is earlier than or equal to (or not later than more than 16 us) the ending symbol of the PDSCH scheduled by the first PDCCH, then the set of DL transmissions including the group of PDCCHs and the PDSCHs scheduled by the group of PDCCHs can be reasonably determined to be considered in the same COT.

[0028] The UE can determine that the CSI-RS transmission power is the same if the reception occasions are within a channel occupancy duration indicated by DCI 2_0 or a running timer or configuration, or within a set of DL transmissions that satisfy certain timing constraints (e.g., small gap between transmissions).

[0029] If at least one of a slot format indication (SFI) field and a channel occupancy (CO) duration field is configured in DCI 2_0, the UE can average measurements of two or more instances of a periodic or semi-persistent non-zero power (NZP) CSI-RS for channel measurements or interference measurements that occur in the indicated remaining CO duration. The UE can not average measurements of two or more instances of a periodic or semi-persistent NZP CSI-RS for channel measurements or interference measurements that do not occur in the indicated remaining CO duration.

[0030] If neither SFI field nor CO duration field is configured in DCI 2_0 but CSI-RS- ValidationWith-DCI-r16 is configured, for channel measurement or interference measurement occurring within a duration occupied by a set of PDSCH and / or CSI-RS(s) (including PDCCH(s) scheduled / triggered) scheduled / triggered to the UE in all orthogonal frequency division multiplexing (OFDM) symbols, the UE can average measurements of two or more instances of periodic or semi-persistent NZP CSI-RS. For channel measurement or interference measurement occurring within a duration occupied by a set of PDSCH and / or CSI-RS(s) (including PDCCH(s) scheduled / triggered) scheduled / triggered to the UE in not all OFDM symbols, the UE can not average measurements of two or more instances of periodic or semi-persistent NZP CSI-RS.

[0031] Figure 4 A flowchart 400 of a method of operating a UE according to an embodiment is shown. At 402, the UE receives at least one DL transmission. At 404, the UE determines CSI-RS occasions in the DL transmission.

[0032] At 406, the UE determines whether the power of each of the CSI-RS occasions is the same. The UE can determine a COT of a DCI included in the DL transmission and determine that the power of the CSI-RS occasions is the same when each of the CSI-RS occasions occurs within the COT. The UE can receive a set of DL transmissions and determine that the power of the CSI-RS occasions is the same when the CSI-RS occasions occur within the set of DL transmissions separated by a predetermined gap size. The UE can run a timer for a predetermined duration and determine that the power of the CSI-RS occasions is the same when the CSI-RS occasions occur within the predetermined duration. The UE can determine that the power of the CSI-RS occasions is the same when the CSI-RS occasions occur between a detected DCI and a PDSCH scheduled by the detected DCI. The UE can be FBE and determine that the power of the CSI-RS occasions is the same when each of the CSI-RS occasions occurs within a predetermined transmission duration.

[0033] At 408, the UE averages the respective measurements when the power of each of the CSI-RS occasions is determined to be the same.

[0034] For operation with shared spectrum channel access, if a UE is configured with a CSI-ReportConfig with the higher layer parameter reportQuantity set to 'cri-RI-PMI-CQI', 'cri-RI-ii', 'cri-RI-ii-CQI', 'cri-RI-CQI', or 'cri-RI-LI-PMI-CQI', the UE can derive the CSI parameters without averaging over two or more instances of any periodic or semi-persistent nzp-CSI-RS resources in the corresponding nzp-CSI-RS-ResourceSet for channel measurement or interference measurement located in different DL transmissions if the UE is provided at least one of SlotFormatIndicator or CO-DurationList-r16 (e.g., when the CSI-RS occasion is within one COT), or if the UE is neither provided CO-DurationPerCell-r16 nor SlotFormatIndicator but is provided CSI-RS-ValidationWith-DCI-r16 (e.g., when the CSI-RS occasion is part of a set of DL transmissions) in case the instances of nzp-CSI-RS resources occur in a set of symbols that are not all occupied by the PDSCH and / or aperiodic CSI-RS(s) and corresponding PDSCH(s) indicated by DCI format.

The communication module 590 can include one or more communication processors (CPs) that are operated independently of the processor 520 (e.g., an AP) and supports direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 590 can include a wireless communication module 592 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 594 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with the external electronic device via a first network 598 (e.g., a short-range communication network, such as Bluetooth, Bluetooth Low Energy, Wi-Fi direct, or infrared data association (IrDA)) or a second network 599 (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules can be implemented as a single component (e.g., a single IC) or can be implemented as separate components (e.g., separate ICs) from each other. The wireless communication module 592 can use subscriber information (e.g., an international mobile subscriber identity (IMSI) stored in the subscriber identification module 596) to identify and authenticate the electronic device 501 in a communication network, such as the first network 598 or the second network 599. TM The communication module 590 can support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 501 and an external electronic device (e.g., the electronic device 502, the electronic device 504, or a server 508) and performing communication via the established communication channel. The communication module 590 can include one or more communication processors (CPs) that are operated independently of the processor 520 (e.g., an AP) and supports direct (e.g., wired) communication or wireless communication.

The wireless communication module 592 can use subscriber information (e.g., an international mobile subscriber identity (IMSI) stored in the subscriber identification module 596) to identify and authenticate the electronic device 501 in a communication network, such as the first network 598 or the second network 599.

[0052] The antenna module 597 can transmit or receive a signal or power to or from the outside (e.g., an external electronic device) of the electronic device 501. According to an embodiment, the antenna module 597 can include one or more antennas, and therefrom, at least one antenna appropriate for a communication scheme used in a communication network, such as the first network 598 or the second network 599, can be selected, for example, by the communication module 590 (e.g., the wireless communication module 592). The signal or the power can then be transmitted or received between the communication module 590 and an external electronic device via the selected at least one antenna.

[0053] At least some of the above-described components can be coupled mutually, and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

[0054] According to an embodiment, commands or data can be transmitted or received between the electronic device 501 and an external electronic device 504 via the server 508 coupled with the second network 599. Each of the electronic devices 502 and 504 can be a device of a same type as or different from the electronic device 501. All or some of the operations performed by the electronic device 501 can be performed by one or more external electronic devices 502, 504, or 508. For example, if the electronic device 501 is to perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 501, instead of, or in addition to, performing the function or the service, can request one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request can perform at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer a result of the performance to the electronic device 501. The electronic device 501 can provide the result, whether or not the result is further processed, as at least part of a reply to the request. To that end, for example, cloud computing, distributed computing, or client-server computing technology can be used.

[0055] One embodiment can be implemented as software (e.g., the program 540) including one or more instructions stored in a storage medium (e.g., the internal memory 536 or the external memory 538) readable by a machine (e.g., the electronic device 501). For example, the processor of the electronic device 501 can invoke at least one of the one or more instructions stored in the storage medium, and execute at least one of the one or more instructions under control of the processor, with or without using one or more other components. Thus, the machine can be operated to perform at least one function according to the at least one instruction invoked by the processor. The one or more instructions can include a code generated by a compiler or a code executed by an interpreter. The machine-readable storage medium can be provided in the form of a non-transitory storage medium. The term "non-transitory" indicates that the storage medium is tangible, and does not include a signal (e.g., an electromagnetic wave), but the term does not limit the location or the type of the storage medium. The machine-readable storage medium can be provided in the form of a tangible storage medium, such as a flash drive, a compact disk (CD), a digital versatile disk (DVD), and the like.

[0056] According to an embodiment, the method of the disclosure can be included and provided in a computer program product. The computer program product can be traded as a product between a seller and a buyer. The computer program product can be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed online via an application store (e.g., PlayStore TM) online distribution (e.g., download or upload), or directly between two user devices (e.g., smartphones). If distributed online, at least a portion of the computer program product may be temporarily generated or at least temporarily stored in a machine-readable storage medium, such as a memory of a manufacturer's server, a server of an application store, or a relay server.

[0057] According to one embodiment, each component (e.g., module or program) of the above-mentioned components can include a single entity or multiple entities. One or more of the above-mentioned components can be omitted, or one or more other components can be added. Alternatively or additionally, multiple components (e.g., modules or programs) can be integrated into a single component. In this case, the integrated component can still perform one or more functions of each of the multiple components in the same or similar manner as performed by a corresponding one of the multiple components before integration. The operations performed by a module, program or another component can be performed sequentially, in parallel, repeatedly or heuristically, or one or more operations can be performed or omitted in a different order, or one or more other operations can be added.

[0058] Although certain embodiments of the present disclosure have been described in the detailed description of the present disclosure, the present disclosure may be modified in various forms without departing from the scope of the present disclosure. Therefore, the scope of the present disclosure should not be determined based solely on the described embodiments, but rather on the appended claims and their equivalents.
