[0029] Some aspects of the present disclosure include apparatuses and methods for implementing, for example, channel state information (CSI) capacity reporting and cross-carrier scheduling for Rel-15 and / or Rel-16 (and subsequent 3GPP releases). For example, systems and methods for designs associated with determining and reporting channel state information reference signal (CSI-RS) resources are provided. Additionally, systems and methods for cross-carrier scheduling for CSI measurement and CSI reporting are provided.

[0030] According to some aspects, a user equipment (UE) operating according to the New Radio (NR) of the 5th generation (5G) radio technology defined by the 3rd Generation Partnership Project (3GPP) Release 15 (Rel-15) and / or Release 16 (Rel-16) (and subsequent 3GPP releases) can report channel state information (CSI) to a network with which the UE communicates. For example, the UE can report CSI to a base station (e.g., a next generation node B (gNB)) with which the UE communicates. According to some aspects, the CSI report may include, but is not limited to: a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), an SS / PBCH (synchronization signal (SS) / physical broadcast channel (PBCH)) block resource indicator (SSBRI), a layer indicator (LI), a rank indicator (RI), and / or an L1-RSRP (L1-reference signal received power) value associated with at least one communication link over which the network communicates with the UE.

[0031] Resources (e.g., CSI-RS ports and / or CSI-RS resources) used by the UE for measuring and / or reporting CSI are controlled by a base station (e.g., a gNB). According to some examples, the UE uses CSI-RS ports and / or CSI-RS resources for CSI measurement and reporting. The base station controls the resources via a CSI report configuration set by the base station. The base station transmits a CSI report configuration to the UE via a CSI report configuration message (e.g., downlink control information (DCI)) to trigger a CSI report.

[0032] According to some aspects, the base station sets the CSI reporting configuration for the UE based on the CSI capability report received by the base station from the UE. In some aspects, the CSI capability report may include a certain number of CSI-RS resources. According to some aspects, the UE determines the number of CSI-RS resources based on the UE's capabilities. For example, the capabilities of the UE may depend on the memory capabilities of the UE or the computing capabilities of the UE. A UE equipped with a large-capacity memory component and / or a high-performance processing component may have a larger number of CSI-RS resources and a greater CSI capability. In some aspects, the UE may determine the number of CSI-RS resources based on the attributes of the CSI report. For example, the attributes of the CSI report may include the memory and / or computing requirements for measuring and reporting CSI.

[0033] According to some aspects, the UE may generate a CSI capability report based on the slot duration. For example, the CSI capability report may indicate the number of CSI-RS resources that the UE can occupy during the slot duration. The slot duration may correspond to the subcarrier spacing (SCS). In one example, if the SCS is 15 KHz, the slot duration may be 1 ms. In another example, if the SCS is 30 KHz, the slot duration may be 0.5 ms. The SCS may include 15 KHz, 30 KHz, 60 KHz, 120 KHz, 240 KHz, or other values.

[0034] According to some aspects, the UE may be connected to one or more cells via one or more base stations. For example, the UE may be connected to a first cell via a base station. The first cell may be the primary cell. The UE may also be connected to a second cell via the base station. The second cell may be a secondary cell.

[0035] According to some aspects, the UE may communicate with the first cell using a first SCS and communicate with the second cell using a second SCS. For example, the UE may communicate with the first cell using a first SCS of 15 KHz and a first slot duration of 1 ms; the UE may communicate with the second cell using a second SCS of 60 KHz and a second slot duration of 0.25 ms. In some aspects, the UE may communicate with the first cell and the second cell synchronously. Specifically, one first slot duration may be aligned with four second slot durations. According to some aspects, the UE may determine a first number of CSI-RS resources for the first cell for each of the first slot durations and determine a second number of CSI-RS resources for the second cell for each of the second slot durations.

[0036] According to some aspects, a UE may generate a CSI capability report based on a second time slot duration (e.g., a smaller time slot duration). In some examples, the CSI capability report may include a total number of CSI-RS resources, which may be equal to the sum of a first number of CSI-RS resources and a second number of CSI-RS resources.

[0037] According to some aspects, a UE may generate a CSI capability report based on a first time slot duration (e.g., a larger time slot duration). The CSI capability report may include a total number of CSI-RS resources, e.g., which may be equal to the sum of a first number of CSI-RS resources and four times a second number of CSI-RS resources.

[0038] According to some aspects, a UE may communicate asynchronously with a first cell and a second cell. The UE may determine CSI capabilities for each time slot based on an overlap between the first cell and the second cell. Additional details are discussed below.

[0039] According to some aspects, a UE may send a CSI capability report to a first cell (e.g., a primary cell). In some aspects, the UE may send a CSI capability report to a second cell (e.g., a secondary cell). In certain aspects, the UE may send a CSI capability report to both the first cell and the second cell.

[0040] According to some aspects, a UE may generate a CSI capability report per frequency band. Thus, the CSI capability report represents the CSI capabilities of the frequency band. If the frequency band is within frequency range 1 (FR1) between 450 MHz and 6,000 MHz, the CSI capability may not be greater than a first maximum value. If the frequency band is within frequency range 2 (FR2) between 24,250 MHz and 52,600 MHz, the CSI capability may not be greater than a second maximum value. In some aspects, the first maximum value is different from the second maximum value. In some examples, the first maximum value is equal to 8 and the second maximum value is equal to 4. In other examples, other first maximum values and second maximum values may be allocated.

[0041] According to some aspects, a UE may generate a CSI capability report for each frequency band combination, where each frequency band combination combines one or more frequency bands via carrier aggregation. In some aspects, one or more of the frequency bands in the frequency band combination may share the attributes of the above CSI report. In some aspects, one or more of the frequency bands may be consecutive frequency bands in the frequency band, non-consecutive frequency bands in the frequency band, or frequency bands in multiple frequency bands.

[0042] According to some aspects, if one or more frequency bands include a first part of one or more frequency bands in FR1 and a second part of one or more frequency bands in FR2, the UE may generate a first CSI capability report corresponding to the first part of the one or more frequency bands and a second CSI capability report corresponding to the second part of the one or more frequency bands.

[0043] According to some aspects, if the UE generates a CSI capability report indicating support for two non-periodic CSI (AP-CSI), e.g., maxNumberAperiodicCSI-PerBWP-ForCSI-Report = 2. The UE may indicate one or more supported type combinations of CSI reports in the CSI capability report. In some aspects, the one or more supported type combinations may include a first CSI measurement type and a second CSI measurement type. The first CSI measurement type may have less computational complexity than the second CSI measurement type. For example, the first CSI measurement type may be "Rel-15 type Il single panel", and the second CSI measurement type may be "Rel-16 type II". In some aspects, the one or more supported type combinations may include two different reporting parameters, e.g., two different reporting parameters that are independent of each other or do not overlap with each other. For example, the two different reporting parameters may be a combination of "cri-RI-i1-CQI" and "cri-RSRP" or a combination of "cri-RI-i1-CQI" and "ssb-Index-RSRP".

[0044] According to some aspects, the UE may indicate one or more restricted type combinations of CSI reports in the CSI capability report. In certain aspects, the one or more restricted type combinations may include a third CSI measurement type and a fourth CSI measurement type. The third CSI measurement type has a similar computational complexity to the fourth CSI measurement type. For example, the third CSI measurement type and the fourth CSI measurement type may both be "Rel-15 type Il single panel" or both be "Rel-16 type II". In certain aspects, the one or more restricted type combinations may include two ambiguous reporting parameters, e.g., two ambiguous reporting parameters that are dependent on each other or overlap with each other. For example, the two ambiguous reporting parameters may be a combination of "cri-RSRP" and "ssb-Index-RSRP".

[0045] According to some aspects, a UE may perform cross-carrier scheduling between a first cell and a second cell. For example, a base station receives a CSI capability report from the UE, generates a CSI report configuration message, and transmits the CSI report configuration message to the UE. In some examples, the CSI report configuration message may include DCI. The base station may transmit the CSI report configuration message to the UE via a physical downlink control channel (PDCCH) in the first cell. Thus, the UE receives the CSI report configuration message from the first cell via the base station.

[0046] In some aspects, the UE may process the CSI report configuration message. Based on the CSI report configuration message, the UE may be triggered to measure a CSI reference signal (CSI-RS) received from the second cell via the base station. In some aspects, the base station may transmit the CSI-RS to the UE.

[0047] According to some aspects, the UE may be connected to a third cell via the base station. The UE may be scheduled to generate a CSI report based on the result of measuring the CSI-RS received from the second cell. The UE may also be scheduled to transmit the CSI report to the third cell via the base station. In some aspects, the UE may be scheduled to generate and transmit a CSI report based on the CSI report configuration message received from the first cell via the base station.

[0048] According to some aspects, processing the CSI report configuration message, measuring the CSI-RS, and generating the CSI report by the UE require computing resources of the UE, such as a CSI processing unit. The UE may indicate, in the CSI capability report, a plurality of simultaneous CSI processes that the UE is capable of handling. Each of the CSI processes may include CSI steps, such as the processing, measuring, and generating described above.

[0049] According to some aspects, the CSI steps of each CSI process share CPU resources, such as a CSI processing unit. Each of the CSI steps occupies a portion of the CPU resources in a timely manner. For example, the CPU resources may have a first duration, a second duration, and a third duration. The UE may use the CPU resources during the first duration to process the CSI report configuration message; the UE may use the CPU resources during the second duration to measure the CSI-RS; and the UE may use the CPU resources during the third duration to generate the CSI report. In certain aspects, the second duration may be greater than the first duration and / or the third duration.

[0050] Figure 1An exemplary system 100 implementing a design for New Radio (NR) channel state information (CSI) capability reporting and cross-carrier scheduling in accordance with some aspects of the present disclosure is shown. The exemplary system 100 is provided for illustrative purposes only and does not limit the disclosed aspects. System 100 may include, but is not limited to, a base station 101 (such as an eNB, gNB, etc.) and an electronic device (represented as UE 105). UE 105 may be implemented as an electronic device configured to operate based on multiple wireless communication technologies. Some of these technologies may include, but are not limited to, technologies based on the 3rd Generation Partnership Project (3GPP) standards. For example, UE 105 may include an electronic device configured to operate using one or more 3GPP releases (such as Release 15 (Rel-15), Release 16 (Rel-16), or subsequent 3GPP releases). UE 105 may include, but is not limited to, a wireless communication device, a smart phone, a laptop computer, a desktop computer, a tablet computer, a personal assistant, a monitor, a television, a wearable device, an Internet of Things (IoT) device, a vehicle communication device, etc. Base station 101 may include one or more nodes configured to operate based on multiple wireless communication technologies (such as, but not limited to, technologies based on 3GPP standards). For example, base station 101 may include nodes configured to operate using Rel-15, Rel-16, or subsequent 3GPP releases. In some aspects, base station 101 may belong to cell 103. UE 105 may be connected to cell 103 via base station 101. Cell 103 may be the primary cell of UE 105.

[0051] UE 105 may be connected to base station 101 using one or more communication links 107 and communicate with the base station. Each of the communication links may include at least one uplink (UL) connection and at least one downlink (DL) connection. According to some aspects, UE 105 may determine its CSI capability and generate a CSI capability report. UE 105 may transmit the CSI capability report to base station 101 via one of the at least one UL connections. Base station 101 may generate a CSI report configuration message, such as downlink control information (DCI), and transmit the CSI report configuration message to UE 105 via one of the at least one DL connections.

[0052] According to some aspects, UE 105 may be connected to a second cell (not shown) via base station 101. According to some aspects, the base station may generate CSI-RS and transmit the CSI-RS to UE 105 in the second cell via a downlink (DL) connection between base station 101 and UE 105. In certain aspects, UE 105 may trigger the measurement of CSI-RS based on the CSI report configuration message.

[0053] According to some aspects, the UE 105 may be connected to a third cell via the base station 101. The UE 105 may generate a CSI report based on the result of measuring CSI-RS. The UE 105 may transmit the CSI report to the base station 101 via an uplink (UL) connection between the UE 105 and the base station 101 in the third cell.

[0054] According to some aspects, the UE may indicate one or more cells that are allowed to trigger / schedule the measurement of CSI-RS received from a second cell. For example, the UE may indicate that the first cell is allowed to trigger / schedule the measurement of CSI-RS received from the second cell. If the UE receives a second CSI report configuration message from the third cell via the base station 101 to trigger the measurement of CSI-RS received from the second cell, the UE may reject the trigger. In some aspects, the CSI-RS received from a primary cell, such as the first cell, may be triggered / scheduled only by a CSI report configuration message received from the primary cell, such as the first cell.

[0055] According to some aspects, different CSI reports (e.g., ReportConfigId) may be used to trigger the CSI reporting process including CSI-RS measurement, where each report may be based on CSI-RS measurement in a different carrier. In some aspects, corresponding CPU resources for each CSI reporting process are occupied on the carrier on which the UE performs CSI-RS measurement for the CSI reporting process, such as the processing unit described above.

[0056] In some aspects, the CSI reporting process including CSI-RS measurement may be triggered by multiple CSI reports (e.g., ReportConfigId). For each ReportConfigId, all CSI-RS (e.g., CMR / CSI-IM / NZP-IMR) for both channel measurement and interference measurement are located in the same component carrier. Alternatively, for all CSI reporting processes, all CSI-RS (e.g., CMR / CSI-IM / NZP-IMR) for both channel measurement and interference measurement are located in the same component carrier.

[0057] Figure 2FIG. 200 is a block diagram of an exemplary system of an electronic device implementing a mechanism for a New Radio (NR) channel state information (CSI) capability report and cross-carrier scheduling design in accordance with some aspects of the present disclosure.

According to some examples, the operating system 252 may be stored in the memory 250. The operating system 252 may manage data transfer from the memory 250 and / or the one or more applications 254 to the processor 210 and / or the one or more transceivers 220. In some examples, the operating system 252 maintains one or more network protocol stacks (e.g., Internet protocol stack, cellular protocol stack, etc.) that may include multiple logical layers. At the corresponding layers of the protocol stack, the operating system 252 includes control mechanisms and data structures to perform functions associated with that layer.

[0060] System 200 may also include a communication infrastructure 240. The communication infrastructure 240 provides communication, for example, between the processor 210, one or more transceivers 220, and the memory 250. In some specific implementations, the communication infrastructure 240 may be a bus. The processor 210, together with the instructions stored in the memory 250, performs operations that enable the system 200 of the system 100 to implement the mechanisms for CSI capability reporting and cross-carrier scheduling as described herein. Additionally or alternatively, one or more transceivers 220 perform operations that enable the system 200 of the system 100 to implement the mechanisms for NR CSI capability reporting and cross-carrier scheduling as described herein.

Additionally, one or more transceivers 220 transmit and receive communication signals that support the mechanisms for measuring a communication link and generating and transmitting a CSI report. According to some aspects, one or more transceivers 220 may be coupled to an antenna 260. The antenna 260 may include one or more antennas that may be of the same or different types. The one or more transceivers 220 allow the system 200 to communicate with other devices that may be wired and / or wireless. In some examples, the one or more transceivers 220 may include processors, controllers, radio components, sockets, plugs, buffers, and similar circuits / devices for connecting to and communicating on a network. According to some examples, the one or more transceivers 220 include one or more circuits for connecting to a wired network and / or a wireless network and communicating on the wired network and / or the wireless network.

[0062] According to some aspects of the present disclosure, the one or more transceivers 220 may include a cellular subsystem, a WLAN subsystem, and / or a Bluetooth TM subsystem, each including its own radio transceiver and protocol, as will be understood by those skilled in the art based on the discussion provided herein. In some specific implementations, the one or more transceivers 220 may include more or fewer systems for communicating with other devices.

[0063] In some examples, the one or more transceivers 220 may include one or more circuits (including a WLAN transceiver) for enabling connection and communication via a WLAN network (such as, but not limited to, a network based on the standards described in IEEE 802.11).

[0066] According to some aspects of the present disclosure, the processor 210 implements the methods and mechanisms discussed in the present disclosure alone or in combination with computer instructions stored in the memory 250 and / or one or more transceivers 220. For example, the processor 210 implements the mechanisms for NR CSI capability reporting and cross-carrier scheduling alone or in combination with computer instructions stored in the memory 250 and / or one or more transceivers 220. According to some aspects of the present disclosure, the processor 210 may determine the CSI capability of the UE based on the attributes of the processor 210 and / or the memory 250 alone or in combination with computer instructions stored in the memory 250. In some aspects, the processor 210 may determine the CSI capability of the UE based on the memory requirements and / or the computational complexity of processing the CSI report alone or in combination with computer instructions stored in the memory 250. In certain aspects, the processor 210 alone or in combination with computer instructions stored in the memory 250 and / or one or more transceivers 220 may generate a CSI capability report and transmit the capability report to a base station (e.g., Figure 1 base station 101) of Figure 1 base station 101).

[0067] According to some aspects, the memory 250 may include device capabilities 256. The device capabilities 256 may include information indicating that the system 200 is configured to process CSI report configuration messages received from a base station, measure the received CSI-RS, and generate a CSI report based on the results of measuring the CSI-RS.

[0068] According to some aspects, processor 210 may include one or more processing units, e.g., one or more CSI processing units. The number of one or more processing units may indicate the number of simultaneous CSI processes that the UE can support. In certain aspects, a CSI report configuration message sent from a base station to the UE may request a number of CSI reports that is less than the number of one or more processing units.

[0069] As discussed in more detail below with respect to Figures 3 to 8 , processor 210 may implement different mechanisms for CSI capability reporting and cross-carrier scheduling as discussed for system 100 with respect to Figure 1 .

[0070] Figure 3 Exemplary method 300 of a system (e.g., a user equipment (UE)) for supporting mechanisms for CSI capability reporting and cross-carrier scheduling in accordance with some aspects of the present disclosure is shown. For convenience and not limitation, reference may be made to the elements of Figure 1 , Figure 2 and Figure 9 for description. Figure 3 Method 300 may represent the operation of an electronic device (e.g., the UE 105 of Figure 1 ) implementing CSI capability reporting and cross-carrier scheduling. Method 300 may also be performed by the system 200 of Figure 2 and / or the computer system 900 of Figure 9 . However, method 300 is not limited to the specific aspects depicted in those figures and may be performed using other systems, as will be understood by those skilled in the art. It should be understood that not all operations may be required and that these operations may not be performed in the same order as shown in Figure 3 .

[0071] At 302, the UE generates a CSI capability report. As described above, the UE may generate a CSI capability report based on the UE's memory component and processing unit (e.g., the memory 250 and processor 210 of Figure 2 ). The UE may also generate a CSI capability report based on the memory requirements and computational complexity of the CSI report. More details are discussed below in Figure 4 .

[0072] At 304, the UE transmits the CSI capability report to a base station (e.g., the base station 101 of Figure 1 ) via a UL connection (e.g., a UL connection in one or more communication links 107 of Figure 1 ).

[0073] At 306, the UE receives a Channel State Information (CSI) report configuration message from the base station. The CSI report configuration message may include a request from the UE for a CSI report update. In some aspects, the CSI report configuration message may include DCI. The base station may generate the CSI report configuration message based on the CSI capability report received from the UE. For example, the CSI capability report may request a certain number of CSI-RS resources. The base station may generate the CSI report configuration message based on that number of CSI-RS resources.

[0074] At 308, the UE receives a Channel State Information Reference Signal (CSI-RS) from the base station belonging to the first cell. The first cell may be the primary cell of the UE. In some aspects, the UE may receive the CSI-RS from the second cell via the base station. The second cell may be a secondary cell.

[0075] At 310, the UE processes the CSI report configuration message and triggers a CSI report by scheduling CSI measurements. In certain aspects, the UE may schedule CSI measurements for the CSI-RS received from the second cell.

[0076] At 312, the UE measures the CSI-RS, generates a CSI report based on the measurement results, and sends the CSI report to the base station.

[0077] Figure 4 An exemplary method 400 of step 302 in accordance with some aspects of the present disclosure is shown. For convenience and not limitation, reference may be made to Figure 3 the elements of Figure 1 , Figure 2 and Figure 9 to describe Figure 4 . Method 400 may represent the operation of an electronic device (e.g., Figure 1 the base station 101 of Figure 2 ) that implements a CSI capability report. Method 400 may also be executed by Figure 9 the system 200 of Figure 4 and / or

[0078] Figure 9 the computer system 900 of Figure 4 . However, method 400 is not limited to the specific aspects depicted in those figures and may be executed using other systems, as will be understood by those skilled in the art. It should be understood that not all operations may be required and that these operations may not be executed in the same order as shown in Figure 4 .

[0078] At 402, the UE determines a first quantity of CSI-RS resources corresponding to a first slot duration of a first cell. For example, the UE may be able to handle four CSI reports of the first cell or a carrier component of the first cell during the first slot duration. The first slot duration corresponds to a first SCS of the first cell. For example, if the SCS of the first cell is 15 KHz, the first slot duration may be 1 ms. In another example, if the SCS of the first cell is 30 KHz, the first slot duration may be 0.5 ms. The SCS may include 15 KHz, 30 KHz, 60 KHz, 120 KHz, 240 KHz, or any other value.

[0079] The UE may determine the first quantity of CSI-RS resources based on the UE's capabilities (e.g., the size of a memory component such as Figure 2 memory 250) or the computing capabilities of a processor such as Figure 2 processor 210). The UE may also determine the first quantity of the first CSI resources based on the memory requirements and computational complexity of the CSI reports, e.g., the SCS of the first cell, the size of the carrier component of the first cell, and the type of CSI report.

[0080] At 404, the UE determines a second quantity of CSI-RS resources corresponding to a second slot duration of a second cell. The UE may determine the second quantity of CSI-RS resources in a similar manner as described in step 402. In some aspects, the second duration may be different from the first duration because the SCS of the first cell may be different from the SCS of the second cell.

[0081] At 406, the UE determines a total slot duration based on the first slot duration and the second slot duration. The UE may determine that the total slot duration is equal to the smaller of the first slot duration and the second slot duration. For example, as Figure 5 shown, the first slot duration may be slot 502, and the second slot duration may be slot 504. In one implementation, the length of slot 502 may be 0.25 ms, and the length of slot 504 may be 1 ms. The UE may determine that slot 502 is smaller and the total slot duration is equal to slot 502, e.g., 0.25 ms. Alternatively, the UE may determine that the total slot duration is equal to the larger slot duration. Similar to the above discussion, the UE may determine that the total slot duration is equal to slot 504, e.g., 1 ms.

[0082] At 408, the UE determines the total number of CSI-RS resources for the total slot duration based at least on a first number and a second number of CSI-RS resources. In some aspects, the UE determines the total number of CSI-RS resources for all connected cells such as a first cell and a second cell. In some aspects, the slots of the first cell and the second cell may be synchronous. For example, as Figure 5 shown, slot 504 is aligned with four slots 502.

[0083] According to some aspects, if the UE determines that the total slot duration is equal to slot 502, the total slot duration is covered by one slot 502 and one slot 504. For example, as Figure 5 shown, one slot 502 has 4 CSI-RS resources and one slot 504 has 4 CSI-RS resources. The UE may determine that the total number of CSI-RS resources is equal to 8 CSI-RS resources, which is the sum of the number of CSI-RS resources of one slot 502 and one slot 504.

[0084] In some aspects, the UE determines the total number of CSI-RS resources for each slot (e.g., Figure 5 each slot 502 as shown). As described above, the UE may determine that the total number of CSI-RS resources for each slot 502 is equal to 8 CSI-RS resources. Alternatively, when determining the total number of CSI-RS resources, the 4 CSI-RS resources in slot 504 may be counted no more than once. For example, the UE may determine that the total number of CSI-RS resources for the first slot 502 is equal to 8, and each of the total numbers of CSI-RS resources for the second slot 502, the third slot 502, and the fourth slot 502 is equal to 4.

[0085] According to some aspects, if the UE determines that the total slot duration is equal to slot 504, the UE may determine that the total number of CSI-RS resources for slot 504 is equal to the number of CSI-RS resources for all slots covered by slot 504. For example, the UE may determine that the total number of CSI-RS resources for slot 504 is equal to 20, which is the sum of the number of CSI-RS resources of one slot 504 and the number of CSI-RS resources of four slots 502.

[0086] In some aspects, the slots of the first cell and the second cell may be asynchronous. For example, as Figure 6As shown, time slot 604 is not aligned with five time slots 602. If the UE determines that the total time slot duration is equal to the time slot 602, for example, a smaller time slot duration, the UE can determine the total number of CSI-RS for each time slot 602. In some aspects, if the time slot 602 completely overlaps with the time slot 604, the CSI-RS resources of the time slot 604 can be counted. For example, the time slot 604 completely overlaps with Figure 6 the second time slot 602, the third time slot 602, and the fourth time slot 602 in Figure 6 . The UE can determine that the total number of CSI-RS resources for the second, third, and fourth time slots 602 is 8, and the total number of CSI-RS resources for the first time slot 602 and the fifth time slot 602 is 4.

[0087] In some aspects, if the time slot 604 partially or completely overlaps with the time slot 602, the CSI-RS resources of the time slot 604 can be counted. For example, the time slot 604 partially overlaps with the first and fifth time slots 602 and completely overlaps with the second, third, and fourth time slots 602. The UE can determine that the total number of CSI-RS resources for each time slot 602 is equal to 8.

[0088] In some aspects, if the time slot 604 overlaps with more than 50% of the time slot 602, the CSI-RS resources of the time slot 604 can be counted. For example, the time slot 604 overlaps with less than 50% of the first time slot 602 shown in Figure 6 Figure 6 and more than 50% of each of the other time slots 602. The UE can determine that the total number of CSI-RS resources for the first time slot 602 is equal to 4, and the total number of CSI-RS resources for all other time slots 602 is equal to 8.

[0089] In some aspects, if the UE determines that the total time slot duration is equal to the time slot 604, for example, a larger time slot duration, the UE can determine the total number of CSI-RS for each time slot 604. In some aspects, if the time slot 602 completely overlaps with the time slot 604, the CSI-RS resources of the time slot 602 can be counted. For example, the first, second, and third time slots 602 completely overlap with the time slot 604. The UE can determine that the total number of CSI-RS resources for the time slot 604 is equal to 16.

[0090] In some aspects, if the time slot 602 partially or completely overlaps with the time slot 604, the CSI-RS resources of the time slot 602 can be counted. For example, Figure 6 all the time slots 602 shown in Figure 6 partially or completely overlap with the time slot 604. The UE can determine that the total number of CSI-RS resources is equal to 24.

[0091] In some aspects, if more than 50% of slot 602 overlaps with slot 604, the CSI-RS resources of slot 602 can be counted. For example, slot 604 overlaps with less than 50% of the first slot 602 as shown in Figure 6 and more than 50% of each of the other slots 602. The UE can determine that the total number of CSI-RS resources is equal to 20.

[0092] At 410, the UE generates a CSI capability report based at least on the total number of CSI-RS resources. For example, the CSI capability report may include the total number of CSI-RS resources for the total slot duration and other parameters.

[0093] Figure 5 An example of the slot durations of a first cell and a second cell in a synchronized state is shown, where slot 502 corresponds to the first cell and slot 504 corresponds to the second cell. As described above, slot 504 completely overlaps with 4 slots 502. Each of slot 502 and slot 504 has 4 CSI-RS resources.

[0094] Figure 6 An example of the slot durations of a first cell and a second cell in an asynchronous state is shown, where slot 602 corresponds to the first cell and slot 604 corresponds to the second cell. As described above, slot 604 completely overlaps with the second, third, and fourth slots 502 and partially overlaps with the first and fifth slots 502. Each of slot 502 and slot 504 has 4 CSI-RS resources.

[0095] Figure 7 An exemplary method 700 of step 302 and step 312 according to some aspects of the present disclosure is shown. For convenience and not limitation, reference may be made to the elements of Figure 3 and Figure 1 and Figure 2 and Figure 9 to describe Figure 7 . Method 700 may represent the operation of an electronic device (e.g., the base station 101 of Figure 1 ) that implements a CSI capability report. Method 700 may also be executed by the system 200 of Figure 2 and / or the computer system 900 of Figure 9 . However, method 700 is not limited to the specific aspects depicted in those figures, and other systems may be used to execute the method, as will be understood by those skilled in the art. It should be understood that not all operations may be required and that these operations may not be executed in the same order as shown in Figure 7 .

[0096] At 702, the UE determines a first duration and a second duration that occupy the UE's CSI processing unit. For example, the first duration may be Figure 8 duration 802, and the second duration may be Figure 8 duration 804. As described above, the processor of the UE, such as Figure 2 processor 210, may include one or more CSI processing units. For example, the processor of the UE may include 10 CSI processing units, indicating that the UE is capable of simultaneously processing 10 CSI reporting procedures.

[0097] At 704, the UE uses the CSI processing unit during the first duration to process the received CSI report configuration message to trigger CSI-RS measurement. As described above, the CSI report configuration message may include DCI for triggering a CSI report. In some aspects, the UE may deframe the CSI report configuration message by identifying the header and payload of the CSI report configuration message. The UE may also decode and / or decrypt the payload to extract the information carried by the CSI report configuration message. In some aspects, deframing, decoding, and / or decrypting occupy the CSI processing unit for up to the first duration.

[0098] At 706, the UE uses the CSI processing unit during the second duration to perform CSI-RS measurement of the CSI-RS. In some aspects, the UE may calculate CSI based on the received CSI-RS. The CSI may include, but is not limited to: Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), CSI-RS Resource Indicator (CRI), SS / PBCH (Synchronization Signal (SS) / Physical Broadcast Channel (PBCH)) Block Resource Indicator (SSBRI), Layer Indicator (LI), Rank Indicator (RI), and / or L1-RSRP (L1-Reference Signal Received Power) associated with at least one communication link over which the network communicates with the UE.

[0099] In some aspects, the CSI-RS measurement occupies the CSI processing unit for up to the second duration. As Figure 8 shown, the first duration and the second duration may be adjacent to each other.

[0100] At 708, the UE generates a CSI report based on the CSI-RS measurement. In some aspects, the UE may determine that it occupies the CSI processing unit of the UE for up to a third duration. For example, the third duration may be Figure 8 duration 806. As Figure 8 shown, the third duration may be adjacent to the second duration. In some aspects, generating the CSI report occupies the CSI processing unit for up to the third duration.

[0101] At 710, the UE transmits a CSI report to a third cell. In some aspects, the UE is connected to the third cell via a base station.

[0102] Figure 8 An example of cross-carrier scheduling of a UE is shown. In some aspects, the UE is connected to a first cell ( Figure 8 Cell A), a second cell ( Figure 8 Cell B), and a third cell ( Figure 8 Cell C). The UE receives a CSI report configuration message, such as DCI, from the first cell. The UE processes the CSI report configuration message to schedule CSI-RS measurements in the second cell. The UE generates and transmits a CSI report to the third cell. In some aspects, as described above, the computation of each cell occupies the processing unit (e.g., Figure 8 the CPU shown in

[0103] for a certain duration. For example, the computation of the first cell occupies the processing unit for a duration of 802. Similarly, the computations of the second cell and the third cell occupy durations of 804 and 806, respectively. Figure 9 Figure 1 Figure 2

[0104] Various aspects can be implemented, for example, using one or more computer systems such as

[0105] the computer system 900 shown in

The computer system 900 also includes user input / output devices 903 that communicate with the communication infrastructure 906 via a user input / output interface 902, such as a monitor, keyboard, pointing device, etc. The computer system 900 also includes a main memory or primary memory 908, such as random access memory (RAM). The main memory 908 may include one or more levels of cache. Control logic (e.g., computer software) and / or data are stored therein.

[0104] The computer system 900 may also include one or more auxiliary storage devices or memories 910. The auxiliary memory 910 may include, for example, a hard disk drive 912 and / or a removable storage device or drive 914. The removable storage drive 914 can be a floppy disk drive, a tape drive, a CD drive, an optical storage device, a tape backup device, and / or any other storage device / drive.

[0105] The removable storage drive 914 can interact with the removable storage unit 918. The removable storage unit 918 includes a computer-usable or readable storage device on which computer software (control logic) and / or data is stored. The removable storage unit 918 can be a floppy disk, magnetic tape, optical disk, DVD, optical storage disk, and / or any other computer data storage device. The removable storage drive 714 reads from and / or writes to the removable storage unit 918 in a well-known manner.

[0106] According to some aspects, the secondary storage 910 can include other devices, means, or other methods for allowing computer programs and / or other instructions and / or data to be accessed by the computer system 900. Such devices, means, or other methods can include, for example, the removable storage unit 922 and the interface 920.

The communication interface 924 enables the computer system 900 to communicate and interact with any combination of remote devices, remote networks, remote entities, etc. (collectively and individually referred to by the reference numeral 928). For example, the communication interface 924 can allow the computer system 900 to communicate with the remote device 928 via the communication path 926, which can be wired and / or wireless and can include any combination of LAN, WAN, the Internet, etc. Control logic and / or data can be transmitted to and from the computer system 900 via the communication path 926.

[0108] The operations in the foregoing aspects can be implemented in various configurations and architectures.
