Description
[0001] This application is a divisional application of application number 202180045931.1, filed on March 31, 2021, entitled "System and method for enhancing channel measurement and beam management". Technical Field
[0002] This disclosure relates generally to wireless communications, including but not limited to systems and methods for channel measurement and beam management. Background Technology
[0003] The standards organization 3GPP is currently specifying a new radio interface (called 5G New Radio (5G NR)) and a next-generation packet core network (NG-CN or NGC). 5G NR will have three main components: the 5G Access Network (5G-AN), the 5G Core Network (5GC), and the User Equipment (UE). To facilitate the implementation of different data services and requirements, the elements of the 5GC (also known as network functions) have been simplified, some based on software and others on hardware, allowing them to be adapted as needed. Summary of the Invention
[0004] The exemplary embodiments disclosed herein are intended to address issues related to one or more problems existing in the prior art, and to provide additional features that will become clear when referred to in conjunction with the accompanying drawings in a detailed description. Example systems, methods, apparatuses, and computer program products are disclosed herein according to various embodiments. However, it should be understood that these embodiments are presented as examples and not as limiting, and that it will be apparent to those skilled in the art who read this disclosure that various modifications can be made to the disclosed embodiments while remaining within the scope of this disclosure.
[0005] At least one aspect relates to a system, method, apparatus, or computer-readable medium. A wireless communication device can receive a configuration from a wireless communication node, the configuration including at least one Channel Measurement Reference Signal (RS) resource (CMR). The wireless communication device can perform at least one CMR measurement according to the configuration. The wireless communication device can send a report to the wireless communication node. The report may include at least one of a CMR index or channel quality.
[0006] In some embodiments, channel quality may include at least one of Reference Signal Received Power (RSRP), Signal-to-Interference-plus-Noise Ratio (SINR), or Channel Quality Information (CQI). In some embodiments, the wireless communication device may determine X sets or X subsets of CMRs from a set of CMRs according to this configuration. In some embodiments, X may be an integer greater than 1. In some embodiments, the wireless communication device may receive a message including a bitmap from a wireless communication node. In some embodiments, the wireless communication device may determine at least one set of CMRs from X sets according to a bitmap. In some embodiments, each subset of the X subsets may have a corresponding (1 / X)th resource from the resources of the CMR sets. In some embodiments, when M CMRs exist in a resource set, each (k+n*X)th CMR in the CMRs may belong to the kth subset of the X subsets. In some embodiments, n may be an integer value that is at least zero and not greater than ((M / X)-1). In some embodiments, the wireless communication device may determine a mapping between a first set of CMRs and a second set of CMRs according to this configuration, each of the first and second sets corresponding to one of the X sets or X subsets.
[0007] In some embodiments, the configuration may include a first bitmap to indicate that at least one CMR pair includes a CMR from a first group and another CMR from either the first or second group, wherein the CMR pair is used to determine channel quality based on multiple CMRs. In some embodiments, the configuration includes a second bitmap to indicate at least one CMR from a first group and a second group, wherein the at least one CMR is to be used to determine channel quality based on a single CMR. In some embodiments, each CMR not indicated by the first bitmap for pairing may be used to determine channel quality based on a single CMR. In some embodiments, each CMR from the first group and the second group may be used to determine channel quality based on a single CMR. In some embodiments, the number of CMR pairs indicated by the first bitmap may be configurable based on the capabilities of the wireless communication device. In some embodiments, the number of CMRs indicated by the second bitmap may be configurable based on the capabilities of the wireless communication device. In some embodiments, multiple CMRs in the first group may be mapped to corresponding CMRs in the second group as CMR pairs for determining channel quality based on multiple CMRs. In some embodiments, the number of multiple CMRs may be determined based on a mapping parameter, or the number of CMRs in the first group and the number of CMRs in the second group.
[0008] In some embodiments, each CMR from the first group and the second group to be used to determine channel quality based on a single CMR may include: all CMRs in the first group and the second group, at least one CMR from the first group or the second group that is not mapped according to the mapping parameters, or at least one CMR indicated by the second bitmap. In some embodiments, the wireless communication device may perform the mapping of resources between the first group and the second group based on the value of the mode parameter. In some embodiments, if the value of the mode parameter is a first value, the wireless communication device may perform the mapping of CMRs between the first group and the second group according to claim 11. In some embodiments, if the value of the mode parameter is a second value, the wireless communication device may perform the mapping of CMRs between the first group and the second group by mapping every two CMRs from different groups, or mapping every two CMRs from different groups and from the same group.
[0009] In some embodiments, if multiple CMR resource pairs share a common CMR, other CMRs in the multiple CMR pairs may be configured to have the same Quasi-Co-location (QCL) type D or to be quasi-co-located with QCL type D. In some embodiments, the report may include measurement information used by the wireless communication node to configure subsequent transmissions. In some embodiments, the measurement information may indicate at least one of the following: the number of downlink or uplink layers, the number of sounding reference signal (SRS) ports, whether multiple CMRs are shared or received with the same panel of the wireless communication device, the panel identifier (ID) of the wireless communication device, or a case index. In some embodiments, case information may be predefined by the wireless communication node. In some embodiments, case information may be reported by the capabilities of the wireless communication device. In some embodiments, in the report, in a first mode, the measurement information may include CMR-specific information in the report group. In some embodiments, in the report, in a second mode, the measurement information may include information shared among all CMRs in the report group or shared among all report groups. In some embodiments, the wireless communication device may receive from the wireless communication node a message for configuring the wireless communication device to send reports according to a first mode or a second mode, depending on the capabilities of the wireless communication device.
[0010] In some embodiments, the report may include a flag value indicating whether the corresponding CMR in the report can be applied to uplink transmissions. In some embodiments, if the flag value is set to a first value, the flag value may indicate that the corresponding CMR can be applied to uplink transmissions. In some embodiments, if the flag value is set to a second value, the flag value may indicate that the corresponding CMR cannot be applied to uplink transmissions. In some embodiments, if the flag value is set to a second value, the flag value may indicate that the corresponding CMR can be applied to uplink transmissions if the scheduling time of a subsequent uplink transmission is greater than a threshold, wherein the threshold is configurable based on the capabilities of the wireless communication device. In some embodiments, the first CMR of each report group in the report can be applied to uplink transmissions. In some embodiments, the first X CMRs of each report group, or all CMRs in the first Y report groups in the report, can be applied to uplink transmissions, where X and Y are positive integer values. In some embodiments, at least one of X or Y is configured via Radio Resource Control (RRC), Media Access Control Element (MAC CE), or other signaling. In some embodiments, the report may include parameters for indicating CMRs with maximum reference signal received power (RSRP) or signal-to-interference-plus-noise ratio (SINR) values.
[0011] In some embodiments, when the reported CMR can be applied to uplink transmissions, the corresponding channel quality is determined by at least one of the following: downlink CMR transmission measurement, or uplink compensation following downlink CMR transmission measurement. In some embodiments, the CMR index may be determined by its global index, which is configured via higher-layer signaling. In some embodiments, the first reported CMR index in the first reported reporting group in the reported group may be determined by its global index. In some embodiments, each remaining CMR index may be determined by its local index within the corresponding CMR group. In some embodiments, the first CMR in each reporting group may come from a first group of CMRs, and the second CMR in each reporting group may come from a second group of CMRs. In some embodiments, the CMR index having the maximum measured reference received power (RSRP) or signal-to-interference-plus-noise ratio (SINR) may be first reported in the first reported reporting group in the reported group. In some embodiments, each CMR index may be determined by its group index of its corresponding CMR group and its local index within the corresponding CMR group.
[0012] In some embodiments, the index of the CMR used to determine channel quality based on multiple CMRs in the report may be determined by the corresponding CMR pair index. In some embodiments, the index of the CMR used to determine channel quality based on a single CMR in the report may be determined by a value unique relative to the CMR pair index. In some embodiments, the wireless communication device may send N reports, which include N measurements of the best channel quality among all CMR pairs and single CMRs. In some embodiments, the wireless communication device may send N reports, which include A measurements of the best channel quality among all CMR pairs and B measurements of the best channel quality among all single CMRs, where A and B are each positive integer values, and A+B=N. In some embodiments, the report may include the signal-to-interference-plus-noise ratio (SINR) determined based on signals from antenna elements corresponding to all receiver branches. In some embodiments, each receiver branch in the receiver branches may be associated with at least one of a panel identifier (ID) or a CMR pair ID. In some embodiments, the report may include a value of the signal-to-interference-plus-noise ratio (SINR) or a channel quality indicator (CQI). In some embodiments, this value may be determined based on a first CMR. In some embodiments, the noise or interference corresponding to this value can be determined based on one or more second CMRs configured in the same CMR pair of the first CMR. In some embodiments, the noise or interference can be further determined based on one or more dedicated interference measurement (IM) resources. In some embodiments, one or more dedicated IM resources can be associated with the first CMR. In some embodiments, one or more dedicated IM resources can be associated with a CMR pair, or with the first CMR or one or more second CMRs configured in the same CMR pair.
[0013] At least one aspect relates to a system, method, apparatus, or computer-readable medium. A wireless communication node can send configuration to a wireless communication device. The configuration may include at least one Channel Measurement Reference Signal (RS) resource (CMR). The wireless communication device can perform at least one CMR measurement according to the configuration. The wireless communication node can receive a report from the wireless communication device. The report may include at least one of a CMR index or channel quality. Attached Figure Description

[0028] 1. Mobile communication technology and environment
[0029] Figure 1 An example wireless communication network and / or system 100 according to embodiments of this disclosure is illustrated, in which the technologies disclosed herein may be implemented. In the following discussion, wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 100". Such an example network 100 includes base station 102 (hereinafter referred to as "BS 102"; also called a wireless communication node) and user equipment device 104 (hereinafter referred to as "UE 104"; also called a wireless communication device) that can communicate with each other via communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 covering a geographic area 101. Figure 1 In this context, BS 102 and UE 104 are contained within the corresponding geographical boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station, which operates with its allocated bandwidth to provide sufficient radio coverage to its intended users.
[0030] For example, BS 102 can operate with the allocated channel transmission bandwidth to provide sufficient coverage to UE 104. BS 102 and UE 104 can communicate via downlink radio frame 118 and uplink radio frame 124, respectively. Each radio frame 118 / 124 can be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, BS 102 and UE 104 are described herein as non-limiting examples of "communication nodes" that can generally practice the methods disclosed herein. According to various embodiments of this solution, such communication nodes can be capable of wireless and / or wired communication.
[0031] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of this solution is shown. System 200 may include components and elements configured to support known or conventional operating characteristics that do not need to be described in detail herein. In one illustrative embodiment, system 200 may be used to transmit (e.g., transmit and receive) data symbols in a wireless communication environment, such as those described above. Figure 1 Wireless communication environment 100.
[0032] System 200 typically includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment unit 204 (hereinafter referred to as "UE 204"). BS 202 includes a BS (Base Station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each module being coupled and interconnected with each other as needed via a data communication bus 220. UE 204 includes a UE (User Equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each module being coupled and interconnected with each other as needed via a data communication bus 240.

[0033] As those skilled in the art will understand, system 200 may also include Figure 2 Any number of other modules besides those shown. Those skilled in the art will understand that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any practical combination thereof.

Whether such functionality is implemented in hardware, firmware, or software can depend on the specific application and design constraints imposed on the system as a whole. Those skilled in the art can implement such functionality in a suitable manner for each specific application, but such implementation decisions should not be construed as limiting the scope of this disclosure.
[0034] According to some embodiments, UE transceiver 230, referred to herein as "uplink" transceiver 230, includes a radio frequency (RF) transmitter and an RF receiver, each including circuitry coupled to antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time-duplex manner. Similarly, according to some embodiments, BS transceiver 210, referred herein as "downlink" transceiver 210, includes an RF transmitter and an RF receiver, each including circuitry coupled to antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 can be time-coordinated such that the uplink receiver circuitry is coupled to uplink antenna 232 for reception of transmissions over radio link 250 while the downlink transmitter is coupled to downlink antenna 212. Conversely, the operation of the two transceivers 210 and 230 can be time-coordinated, such that the downlink receiver is coupled to the downlink antenna 212 for receiving transmissions over the wireless transmission link 250 when the uplink transmitter is coupled to the uplink antenna 232. In some embodiments, there is tight time synchronization with a minimum guard time between changes in duplex direction.
[0035] UE transceiver 230 and base transceiver 210 are configured to communicate via wireless data communication link 250 and cooperate with RF antenna arrangements 212 / 232 appropriately configured to support specific wireless communication protocols and modulation schemes. In some illustrative embodiments, UE transceiver 210 and base transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that this disclosure is not necessarily limited to application to specific standards and associated protocols. Rather, UE transceiver 230 and base transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.
[0036] According to various embodiments, for example, BS 202 may be an evolved Node B (eNB), a serving eNB, a target eNB, a femtocell, or a picocell. In some embodiments, UE 204 may be embodied in various types of user equipment, such as mobile phones, smartphones, personal digital assistants (PDAs), tablets, laptops, wearable computing devices, etc. Processor modules 214 and 236 may be implemented or implemented using a general-purpose processor, content-addressable memory, digital signal processor, application-specific integrated circuit, field-programmable gate array, any suitable programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein.

[0037] Furthermore, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein can be directly embodied in hardware, firmware, software modules executed by processor modules 214 and 236 respectively, or in any practical combination thereof. Memory modules 216 and 234 can be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 can be coupled to processor modules 210 and 230 respectively, such that processor modules 210 and 230 can read information from and write information to memory modules 216 and 234 respectively. Memory modules 216 and 234 can also be integrated into their respective processor modules 210 and 230. In some embodiments, each of memory modules 216 and 234 may include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by processor modules 210 and 230 respectively. Memory modules 216 and 234 may each include non-volatile memory for storing instructions to be executed by processor modules 210 and 230, respectively.
[0038] Network communication module 218 typically refers to the hardware, software, firmware, processing logic, and / or other components of base station 202 used to enable bidirectional communication between base station transceiver 210 and other network components and communication nodes configured to communicate with base station 202. For example, network communication module 218 may be configured to support Internet or WiMAX services. In a typical deployment, without limitation, network communication module 218 provides an 802.3 Ethernet interface, enabling base station transceiver 210 to communicate with conventional Ethernet-based computer networks. In this way, network communication module 218 may include a physical interface for a connection to a computer network (e.g., a mobile switching center (MSC)). The terms “configured for,” “configured to,” and variations thereof, as used herein with respect to the specified operation or function, refer to devices, components, circuits, structures, machines, signals, etc., physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0041] 2. Systems and methods for channel measurement and beam management
[0042] In certain systems (e.g., 5G New Radio (NR), Next Generation (NG) systems, and / or other systems), Multiple Transport Receive Points (MTRP) technology can improve / enhance coverage at cell edges and / or reduce the negative impact of congestion. With the standardization of MTRP technology, the procedures / methods for enhancing downlink (DL) transmission have gradually stabilized. However, current procedures / methods for enhancing uplink (UL) transmission are far from stable. In some scenarios, wireless communication devices (e.g., UEs, terminals, and / or served nodes) may have multi-panel transmission capabilities. If the wireless communication device has multi-panel transmission capabilities, solutions for Channel State Information (CSI) feedback and / or group-based reporting in beam management can be further evaluated.
[0043] The system and method proposed in this paper consider the simultaneous transmission capability of multiple panels in a wireless communication device. Furthermore, the system and method include one or more packet / pairing methods for measuring reference signals (RS) on the side of the wireless communication node (e.g., central processing unit (CPU), ground terminal, base station, gNB, eNB, transmit receiver point (TRP), network (NW), or serving node), and a reporting format on the side of the wireless communication device (e.g., after receiving an instruction). Specifically, one or more of the following topics / issues may be considered.
[0044] A wireless communication node can (e.g., to a wireless communication device) instruct / specify / notify / report measurement resources for a single Transmitter-Receiver Point (STRP) transmission, measurement resources for an MTRP transmission, and / or resources that need to be simultaneously received by the wireless communication device. The wireless communication device can report / notify / provide measurement information after receiving / acquiring instructions from the wireless communication node. For example, measurement information may include a measurement resource index, measurement results, and / or other information.
[0045] The MTRP method can effectively improve / enhance transmission throughput in certain systems (e.g., New Radio Access Technologies (NR) in Long Term Evolution (LTE), LTE-A Advanced, and / or Enhanced Mobile Broadband (eMBB) scenarios) by using multiple Transmitter Receiving Points (TRPs). Using MTRP for sending and / or receiving can effectively reduce / lower the probability of information congestion and / or improve / enhance the reliability of transmission in certain scenarios (e.g., Ultra-Reliable Low-Latency Communication (URLLC) scenarios).
[0046] Based on (or according to) the mapping / relationship / association between the transmitted signal stream and multiple TRPs / panels, multiple coordinated transmit / receive points can be divided / categorized / organized / classified into at least two types. These at least two types can include coherent transmission and / or uncorrelated transmission. For coherent transmission, each data layer can be mapped to multiple TRPs / panels via a weighted vector. However, coherent transmission may place higher / more stringent requirements on the synchronization and / or backhaul link transmission capabilities between TRPs. Furthermore, coherent transmission may have increased sensitivity to several non-ideal factors.
[0047] Noncoherent Joint Transport (NCJT) is less affected by (or less susceptible to) the factors described above. Therefore, NCJT can be used in some systems (e.g., R15) to coordinate multiple transmit / receive points. In NCJT, each data stream can be mapped / associated with a port. Ports can correspond to TRPs / panels with the same Channel Massive Parameter (QCL). In some embodiments, different / separate / distinct data streams can be mapped to different ports with different massive parameters. Not all TRPs can be processed as virtual arrays.
[0048] In some systems (e.g., Rel-17), one or more rules can be defined / configured for CSI reporting in MTRP scenarios. For CSI measurements associated with / related to NCJT reporting settings (e.g., CSI-ReportConfig and / or other settings), wireless communication devices can be configured with Ks ≥ 2 non-zero power (NZP) CSI reference signal (CSI-RS) resources and / or N ≥ 1 NZP CSI-RS resource pairs in the CSI-RS resource set for channel measurement resources (CMR). Each pair can be used for NCJT measurement assumptions. Wireless communication devices can be configured with at least two CMR groups having Ks = K1 + K2 CMRs. This can be achieved by following detailed configuration methods (e.g., Figure 3 (As shown) Identify CMR pairs from at least two CMR groups.
[0049] For beam measurements in multiple simultaneous MTRP transmissions, the wireless communication device can report / specify / indicate a single CSI report. A CSI report may include N beam pairs / groups, and / or M (M>1) beams per pair / group. Different / individual / distinct beams within a pair / group can be received / acquired simultaneously.
[0050] In some embodiments, the beam may correspond to / involve a quasi-co-located (QCL) state, a transmission configuration indicator (TCI) state, a spatial relation state (or a spatial relation information state), a reference signal (RS), a spatial filter, and / or precoding. Specifically:
[0051] a) Transmit (Tx) beams may correspond to / involve QCL states, TCI states, spatial relation states, DL / UL reference signals (e.g., Channel State Information Reference Signal (CSI-RS), Synchronization Signal Block (SSB) (also known as SS / PBCH), Demodulation Reference Signal (DMRS), Probe Reference Signal (SRS), and / or Physical Random Access Channel (PRACH)), Tx spatial filters, and / or Tx precoding.
[0052] b) The received (Rx) beam may correspond to / involve QCL state, TCI state, spatial relation state, spatial filter, Rx spatial filter, and / or Rx precoding.
[0053] c) The beam identifier (ID) may correspond to / involve the QCL state index, TCI state index, spatial relation state index, reference signal index, spatial filter index, precoding index, and / or other indexes.
[0054] In some embodiments, a spatial filter may correspond to the viewpoint of a wireless communication device and / or a wireless communication node. In some embodiments, a spatial filter may refer to a spatial domain filter and / or other filters. In some embodiments, spatial relationship information may include one or more reference RSs. Spatial relationship information may be used to specify / indicate / convey / represent the spatial relationship between a target RS / channel and one or more reference RSs. In some embodiments, a spatial relationship may refer to (multiple) identical / quasi-juxtaposed beams, (multiple) identical / quasi-juxtaposed spatial parameters, and / or (multiple) identical / quasi-juxtaposed spatial filters.

[0058] I. Example 1
[0059] In some embodiments, the wireless communication device may send / transmit / transmit a report to the wireless communication node based on (or according to) at least one CMR. The at least one CMR may be configured by the wireless communication node. In some embodiments, the report may include:
[0060] ●CMR indexes, such as:
[0061] ○ One or more indices of CSI-RS, SS / PBCH blocks, and / or other signals / resources (e.g., SRS).
[0062] ● Channel quality information, such as:
[0063] ○ Reference signal received power (RSRP).
[0064] ○ Signal-to-interference-plus-noise ratio (SINR).
[0065] ○ Channel Quality Information (CQI).
[0066] ■ In some embodiments, the parameters to be reported may depend on the higher-level configuration.
[0067] II. Example 2
[0068] In some embodiments, the wireless communication device can measure / evaluate the channel based on (or according to) the CMR in a configured CMR resource set. To enhance / improve certain methods using NCJT, one or more of the following schemes / options can be considered:
[0069] Configure N CMR resource sets (e.g., N≥2) for the wireless communication device. Each resource set (or each resource group) can be associated with / related to a wireless communication node (e.g., TRP).
[0070] ○ The number of resources in different / separate / distinct resource groups can be the same or different.
[0071] ● Divide / classify / categorize / organize the resource set into N resource subsets (e.g., N≥2).
[0072] ○ Option 1: In some embodiments, M resources can be configured in a resource set. When M resources are configured in a resource set, the first M / N resources in the first part belong to a first subset (or are included in the first subset). The second M / N resources in the second part belong to a second subset (or are part of the second subset). Therefore, the M / N resources in the j-th part belong to the j-th subset.
[0073] ○ Option 2 In some embodiments, M resources can be configured in a resource set. When a resource set has M CMRs, each (k+n*X)th CMR belongs to the kth subset (or a part thereof) of X subsets. In some embodiments, n can be an integer value that is at least zero and / or no greater than ((M / X)-1). For example, M=6 (or other values) resources can be configured in a resource set. If M=6 resources are configured, the resource set can be divided into N=3 resource subsets. The first resource subset may include resources 1 and 4, while the second resource subset may include resources 2 and 5. The third resource subset may include resources 3 and 6.
[0074] • In some embodiments, more than one CMR set (e.g., non-periodic CSI resource settings) can be configured. If more than one CMR set is configured, a bitmap can be used to indicate / specify two or more sets from all configured sets, which correspond to multiple TRPs.
[0075] ○ In the current specification, for non-periodic CSI resource settings, the number of configured CSI-RS resource sets can be S>1. For example, if S=4, a bitmap can be used to select two of the four configured sets, each corresponding to a TRP.
[0076] III. Example 3
[0077] For CSI reports in NCJT scenarios, this document discusses CMR resources (e.g., independently and / or simultaneously as resource pairs) that wireless communication nodes indicate to wireless communication devices. Based on the description in Example 2, groups may include or correspond to the resource sets and / or resource subsets described above.
[0078] ● Rule 1: The mapping between group 0 (e.g., group 1) and group 1 (e.g., group 2) can be performed / configured according to (or based on) a bitmap. Wireless communication nodes can send / transmit / transmit the mapped information to wireless communication devices.
[0079] ○1.1: In some embodiments, only one bitmap may be used to indicate pairing / mapping.
[0080] ■1.1.1: CMR pairs can be determined from (or based on) at least two CMR groups (e.g., group 0 and group 1). Figure 4 An example method 400 for determining a CMR pair from two CMR groups is described. If the bitmap is set / configured to "1" (e.g., CMR3 and CMR1), the corresponding CMR pair can be used for MTRP measurements (e.g., to determine channel quality based on multiple CMRs in the CMR pair). If a CMR is set / configured to "0", the CMR can be used for STRP measurements (e.g., to determine channel quality based on a single CMR). In some embodiments, all resources in group 0 and / or group 1 can be used for STRP measurements.
[0081] ■1.1.2: CMR pairs can be determined from (or based on) only one CMR group (e.g., group 0 or group 1). Figure 5 An example method 500 for determining a CMR pair from one CMR group and / or from two CMR groups is described. If the bitmap is set / configured to "1", the corresponding CMR pair can be used for MTRP measurements (e.g., to determine channel quality based on multiple CMRs in the CMR pair). If the CMR is set / configured to "0", the CMR can be used for STRP measurements (e.g., to determine channel quality based on a single CMR). In some embodiments, all resources in group 0 and / or group 1 can be used for STRP measurements.
[0082] ○1.2: In some embodiments, two bitmaps may be used to indicate / specify / configure pairing and / or STRP measurement, respectively.
[0083] ■ In some embodiments, the two bitmaps may not be limited to two bitmaps, but rather two parts of a single bitmap.
[0084] ■ Figure 6 An example method 600 for indicating CMR pairs is depicted. If the bitmap is set / configured to "1", the corresponding CMR pair can be used for MTRP measurements.
[0085] ■ Figure 7 An example method 700 for indicating STRP measurements is depicted. If the bitmap is set / configured to "1", the corresponding CMR can be used for STRP measurements.
[0086] The number of CMR pairs (or CMRs) indicated / specified by the wireless communication node and / or the number of individual CMRs used for STRP measurements (e.g., the number of 1s in (multiple) bitmaps) may depend on the capabilities of the wireless communication device (or be configured accordingly).
[0087] ● Rule 2:Map the first group (e.g., group 0) and the second group (e.g., group 1) in a predetermined order.
[0088] ○2.1: Configured by (or based on) the wireless communication node.
[0089] Group 0 can have M CMRs (e.g., CMR#1, CMR#2, ..., CMR#M), while Group 1 can have N CMRs (e.g., CMR#1, CMR#2, ..., CMR#N). Parameters S (e.g., S = 0.5, 1, 2, ...) can be configured by the wireless communication node. Multiple CMRs in the first group can be sequentially mapped / associated / related to corresponding CMRs in the second group (e.g., as CMR pairs for MTRP measurements). Parameter S can specify / indicate the number of CMRs in the first group to be mapped to CMRs in the second group.
[0090] ● For example, if S = 2, CMR#1 and #2 from group 0 can be mapped to CMR#1 in group 1 as CMR pairs, such as {CMR#1(group 0), CMR#1(group 1)} and {CMR#2(group 0), CMR#1(group 1)}. Furthermore, CMR#3 and #4 from group 0 can be mapped to CMR#2 in group 1 as CMR pairs, such as {CMR#3(group 0), CMR#2(group 1)} and {CMR#4(group 0), CMR#2(group 1)}.
[0091] ○ If M / N > 2, the CMR that can be used for STRP measurements can be as follows:
[0092] ■Option 1: The remaining CMR in group 0 (e.g., if M=3 and N=1, then there is one remaining CMR in group 0)
[0093] ■ Option 2: All CMRs (e.g., Group 0 and / or Group 1)
[0094] ■ Option 3: CMR indicated by a bitmap (e.g., see 1.2:
[0095] STRP measurement indication).
[0096] ○ If M / N < 2, the CMR that can be used for STRP measurement can be as follows:
[0097] ■Option 1: Residual CMR in Group 1 (or other groups)
[0098] ■ Option 2: All CMRs (e.g., Group 0 and / or Group 1)
[0099] ■ Option 3: CMR indicated by a bitmap (e.g., see 1.2: STRP measurement indication)
[0100] If M / N = 2, the CMR that can be used for STRP measurement can be as follows:
[0101] ■ Option 2: All CMRs (e.g., Group 0 and / or Group 1)
[0102] ■ Option 3: CMR indicated by a bitmap (e.g., see 1.2: STRP measurement indication)
[0103] ○2.2: Use predefined mappings (e.g., wireless communication nodes may not need to configure mapping information).
[0104] ■ Wireless communication devices can determine / configure matching / mapping relationships based on (or on) the number of CMRs configured by the wireless communication node in different / separate groups. For example, a wireless communication device can determine a corresponding number of CMRs in the first group and map them to corresponding CMRs in the second group based on the number of CMRs configured by the wireless communication node in the first group and the number of CMRs configured in the second group.
[0105] ● For example, group 0 can have M CMRs (e.g., CMR#1, CMR#2, ..., CMR#M), while group 1 can have N CMRs (e.g., CMR#1, CMR#2, ..., CMR#N). If M / N = 2, then CMR#1 and CMR#2 in group 0 can be mapped to CMR#1 in group 1. Furthermore, CMR#3 and CMR#4 in group 0 can be mapped to CMR#2 in group 1. If M / N = 1, then CMR#1 in group 0 can be mapped to CMR#1 in group 1. Furthermore, CMR#2 in group 0 can be mapped to CMR#2 in group 1.
[0106] ○2.3: Some embodiments may use / include a matching mode (and / or mode parameters). For example, a wireless communication device may receive mode parameters from a wireless communication node (e.g., depending on the capabilities of the wireless communication device).
[0107] ■Mode 1: Mode parameters can be configured to a first value (e.g., "Enabled" and / or "On") based on (or by using) higher-level signaling (e.g., Radio Resource Control (RRC) and / or Media Access Control Control Element (MAC-CE) signaling). If the mode parameters are configured to a first value, the pairing can be performed / implemented according to the system and methods in 2.1 and / or 2.2.
[0108] ■Mode 2: Mode parameters can be configured to a second value (e.g., "disabled" and / or "off") based on higher-level signaling (e.g., RRC and / or MAC-CE signaling). If the mode parameters are configured to a second value, each pair of CMRs in two CMR groups can be paired. For example, group 0 can have CMR#1 and / or CMR#2, while group 1 can have CMR#3 and / or CMR#4. Configured / assembled CMR pairs can include:
[0109] ● Option 1: CMR pairs from two CMR groups (e.g., different groups). For example, {CMR#1, CMR#3}{CMR#2, CMR#3}{CMR#1, CMR#4}{CMR#2, CMR#4}.
[0110] ● Option 2: CMR pairs from at least one of two (e.g., the same) CMR groups (e.g., from one or both CMR groups). For example, {CMR#1, CMR#3}{CMR#2, CMR#3}{CMR#1, CMR#4}{CMR#2, CMR#4} and {CMR#1, CMR#2}{CMR#3, CMR#4}.
[0111] If multiple CMR pairs share a common CMR, then the other CMRs in the multiple CMR pairs should be configured to have the same Quasi-Co-location (QCL) type D or be quasi-co-located with QCL type D.
[0112] ■ For example, a CMR pair may include {CMR#1, CMR#3}{CMR#2, CMR#3}, where CMR#3 is common between the pairs. Therefore, other CMRs (e.g., CMR#1 and / or CMR#2) may be configured to have the same / corresponding QCL type D and / or be QCLed with QCL type D.
[0113] IV. Example 4
[0114] In some embodiments, the wireless communication device can receive / acquire a measurement reference signal from the wireless communication node. Various aspects of the reports from the wireless communication device are discussed herein.
[0115] ●2.1: Report Content
[0116] In some embodiments, the wireless communication device can simultaneously receive M = 2 CSI-RS and / or SSB resources. M = 2 CSI-RS and / or SSB resources can be received using a single spatial reception filter and / or multiple simultaneous spatial reception filters.
[0117] ■ For a single spatial receive filter, M = 2 CSI-RS and / or SSB resources can be used for spatial diversity, such as Figure 8 As shown in (a).
[0118] ■ For multiple simultaneous spatial receiving filters, M = 2 CSI-RS and / or SSB resources can be used for spatial multiplexing, such as Figure 8 As shown in (b).
[0119] ○2.1.1: In some embodiments, a mapping between the CSI-RS / SSB to be reported and the measurements of the wireless communication device may be considered. The following information may be reported in group-based reporting and / or UE capabilities.
[0120] ■Mode 1: The report may include measurement information, which may include CMR-specific information in the report group (e.g., RI for each CSI-RS / SSB in the group). Figure 9 An example method 900 for reporting information in a first mode (e.g., mode 1) is described.
[0121] ■Mode 2: The report may include measurement information, which may include information shared among all CMRs in the reporting group and / or among all reporting groups. For example, the RI for each group and / or the RI may be shared with all groups. When the RI is shared among all CMRs in the reporting group, the RI may be split / divided / segmented into N parts, which are mapped to N CMRs respectively. Figure 10 An example method 1000 for reporting information in a second mode (e.g., mode 2) is described.
[0122] ■ In some embodiments, the wireless communication node can configure a mode (e.g., mode 1 and / or mode 2) based on (or according to) the capabilities of the wireless communication device. The wireless communication device can receive / receive messages from the wireless communication node. These messages can be used to configure the wireless communication device to send / transmit / emit reports according to the first mode and / or the second mode.
[0123] ■ Measurement information may indicate / specify the number of downlink or uplink layers (e.g., {1, 2, 3, 4, ...}), the number of SRS ports (e.g., {1, 2, 3, 4, ...}), a flag indicating whether multiple CMRs are shared or received by the same panel of a wireless communication device, the panel ID used by the wireless communication device to receive the CMR, and / or a case index (e.g., case-x).
[0124] ● In some embodiments, each scenario can be a combination of one or more of the parameters described above. For example, scenario 1 may correspond to {2-DL layer, 1 SRS port, panel 2}, scenario 2 may correspond to {2-DL layer, 2 SRS ports, panel 1}, and so on. The wireless communication device can report the index of the scenario based on measurements. Scenario information can be predefined / preconfigured by the wireless communication node and / or reported by the capabilities of the wireless communication device (e.g., to save / reduce reporting overhead).
[0125] ■ In some embodiments, candidate values for measurement information may be reported / indicated / specified by a wireless communication device.
[0126] ○2.1.2: To enable / configure separate reporting for uplink (UL) and downlink (DL) transmissions, rules or flags can be used to indicate / specify which RSs can be used for UL transmissions (e.g., subsequent UL transmissions). Flag values can indicate whether the corresponding CMR in the report can be applied to uplink transmissions.
[0127] ■Scenario 1: The flag value can be set / configured to a first value. If the flag value is set to the first value, it indicates that the corresponding CMR can be applied to uplink transmission. If the CMR can be applied to uplink transmission, the spatial relationship of the uplink transmission can be determined based on the CMR. In some embodiments, the flag value can be set / configured to a second value. If the flag value is set to the second value, it indicates that the corresponding CMR cannot be applied to uplink transmission. Figure 11 Example configuration 1100 depicts the flag values.
[0128] ■Scenario 2: In some embodiments, the first CMR of each report group in the report can be applied to uplink transmissions. For example, the first CSI-RS and / or SSBRI in each report group can be used for UL transmissions. Additional parameters can be used to indicate / provide / specify the maximum RSRP / SINR.
[0129] ■Scenario 3: In some embodiments, the first X CMRs of each reporting group, and / or all CMRs of the first Y reporting groups, can be applied to uplink transmissions. For example, the first X CSI-RS / SSBs and / or the first Y reporting groups in a reporting group can be applied to UL transmissions. In some embodiments, X and / or Y can be positive integer values. In some embodiments, X and / or Y can be configured using higher-layer signaling (e.g., RRC signaling and / or MAC-CE signaling). In another example, X and / or Y can be reported in a reporting instance.
[0130] ■ When CMR cannot be applied to uplink transmissions reported by wireless communication devices, at least two possible options / modes / configurations may exist.
[0131] ●Mode 1: CMR cannot be applied to uplink transmission.
[0132] ○ Wireless communication devices may be unable to determine the spatial relationships of uplink transmissions based on CMR.
[0133] ●Mode 2: CMR can be used to determine the spatial relationships of uplink transmissions. However, the scheduling time for subsequent uplink transmissions may exceed a threshold. For example, a corresponding beam may require a longer delay compared to other corresponding beams that are reported to be applicable to UL transmissions. Therefore, the scheduling time (e.g., the scheduling of wireless communication devices by wireless communication nodes via downlink control information (DCI) to receive signals) should be greater than the threshold. The threshold can be configured based on (or according to) the capabilities of the wireless communication devices. Figure 12 Example configuration 1200 for scheduling time is described.
[0134] ■ The RSRP / SINR of the reported CMR applied to uplink transmission can be determined based on the following options:
[0135] ●Option 1: Measurement results can be reported directly based on downlink CMR (e.g., DLCMR transmission measurement).
[0136] ●Option 2: Measurement results can be reported after uplink compensation, which is equivalent to the measurement results from the wireless communication node side during UL transmission.
[0137] V. Example 5
[0138] Example 3 considers the determination of the content reported by the wireless communication device. In this section, the index of the reporting reference signal will be discussed.
[0139] For example, CMRs configured by higher-layer signaling (e.g., RRC signaling) may include group 0 {CMR#1CMR#2CMR#4} and / or group 1 {CMR#5CMR#6CMR#7}. Wireless communication nodes may indicate CMR pairs including {CMR#1CMR#5}, {CMR#1CMR#6}, {CMR#2CMR#7}, and / or {CMR#4CMR#7}. After performing a measurement, the wireless communication device may report / specify / indicate pairs {CMR#1CMR#5} and / or pairs {CMR#4CMR#7}.
[0140] Option 1: The CMR index can be determined by its global index (e.g., global index + global index, global index + global index) as configured via higher-level signaling. In some embodiments, the RS index for all reports can use the same global index configured by the higher-level layer. Figure 13 An example method 1300 for determining the CMR index is described.
[0141] ○ Based on the description of the differential reporting in the current system / method, the differential L1-RSRP / L1-SINR value can be calculated in 2 dB steps with reference to the maximum measured L1-RSRP / L1-SINR value. Therefore, the first CMR index reported in the first group should be the CMR with the best (e.g., the maximum) RSRP / SINR.
[0142] Option 2: The first-reported CMR index in the first-reported report group within the report group can be determined by its global index. Each remaining CMR index can be determined by its local index within the corresponding CMR group (e.g., global index + local index, local index + local index). Local indexes can include or correspond to relative indexes in (multiple) higher-level configuration groups. Figure 14 An example method 1400 for determining the CMR index is described.
[0143] ○ The first CMR index reported in the first group using global indexes should be the CMR with the best (e.g., the largest) RSRP / SINR.
[0144] Option 3: Each CMR index can be divided / splittered into at least two parts (e.g., configuration group index + local index). The first part may include or correspond to the configuration group index. The second part may include or correspond to the intra-group relative index. Figure 15 An example method 1500 for determining the CMR index is described.
[0145] Option 4: Wireless communication devices can report / specify / indicate CMR pair indexes. Figure 16 An example method 1600 for determining the CMR index is described.
[0146] If a wireless communication device needs to perform both MTRP and / or STRP measurements simultaneously, the CMR pairs used for MTRP measurements and those used for STRP measurements are encoded together. For example, {CMR#1CMR#5}, {CMR#1CMR#6}, {CMR#2CMR#7}, and / or {CMR#4CMR#7} can be used for MTRP measurements. CMR#1 and / or CMR#4 can be used for STRP measurements. The wireless communication device can report / specify {CMR#1CMR#5}, {CMR#4CMR#7}, and CMR#1. Figures 17 to 18 An example method is described for encoding the CMR pairs used for MTRP measurements and the CMRs used for STRP measurements together.
[0147] VI. Example 6
[0148] For beam measurements during simultaneous MTRP transmissions, a single CSI report can be supported / used. A single CSI report may include N (e.g., N=1 and / or N=2) beam pairs / groups and / or M (e.g., M>1) beams per pair / group. Different / individual beams in a pair / group can be received simultaneously. When the wireless communication device is configured with a reference signal to measure MTRP and STRP transmissions (e.g., simultaneously) and / or N needs to be greater than 1, the following modes can be considered (e.g., based on the indication of the wireless communication node and / or the capability of the wireless communication device).
[0149] 〃 Mode 1: Wireless communication devices can report / specify / indicate N best (e.g., best among all pairs or a single) CMR (pair) indices and / or corresponding channel quality (e.g., RSRP, SINR, and / or CSI) in all measurement results. Therefore, the CMR index with the highest measured RSRP and / or SINR can be reported first in the reporting group of the report. For example, CMRs configured by higher-layer signaling can include group 0 {CMR#1 CMR#2 CMR#4} and / or group 1 {CMR#5 CMR#6 CMR#7}. CMR pairs configured for MTRP measurements can include or correspond to {CMR#1 CMR#5}, {CMR#1 CMR#6}, {CMR#2 CMR#7}, and / or {CMR#4 CMR#7}. CMRs configured for STRP measurements can include or correspond to CMR#1 and / or CMR#4. Wireless communication devices can report / specify {CMR#1CMR#5}, {CMR#4CMR#7}, and / or CMR#1. Measurement results from wireless communication devices can be sorted / organized in descending order, such as... Figure 19As shown. If an N value of 1 (e.g., N = 1) is indicated, the wireless communication device can report {CMR#1CMR#5} with RSRP 0. In another example, if an N value of 1 (e.g., N = 1) is indicated, the wireless communication device can report {CMR#1CMR#5} with RSRP 0 and / or {CMR#1CMR#6} with RSRP 1.
[0150] 〃 Mode 2: The wireless communication device can report the best CMR (pair) index and / or corresponding channel quality (e.g., RSRP, SINR, and / or CSI) in all MTRP measurement results. The wireless communication device can report / specify B best CMR indices and / or corresponding channel quality (e.g., RSRP, SINR, and / or CSI) in all STRP measurement results, where A+B = N. The values of A and / or B can be determined by the wireless communication node configuration and / or by the capabilities of the wireless communication device. For example, CMRs configured by higher-layer signaling can include group 0 {CMR#1CMR#2CMR#4} and / or group 1 {CMR#5CMR#6CMR#7}. CMR pairs configured for MTRP measurements can include or correspond to {CMR#1CMR#5}, {CMR#1CMR#6}, {CMR#2CMR#7}, and / or {CMR#4CMR#7}. CMRs configured for STRP measurements can include or correspond to CMR#1 and / or CMR#4. When A=1 and B=0 (e.g., N=1) are indicated, the wireless communication device can report / designate / indicate {CMR#1CMR#5} with RSRP 0. When A=1 and B=1 (e.g., N=2) are indicated, the wireless communication device can report / designate / indicate {CMR#1CMR#5} with RSRP 0 and / or CMR#1 with RSRP 4.
[0151] VII. Example 7
[0152] The L1-RSRP-based beam management in Release 15 may not be the optimal solution because it only considers signal strength and not interference. Release 16 introduced an L1-SINR-based downlink beam management mechanism to include interference information for each beam. However, the relevant specifications have not been modified accordingly, therefore, further details need to be standardized.
[0153] SINR of combination A.5.1
[0154] For group-based reporting, a SINR can be calculated / determined for each beam on the wireless communication device side (e.g., according to current specifications). However, to reflect mutual interference between beams, a SINR value can be reported / provided. When a wireless communication device receives and / or transmits signals by simultaneously using multiple beams, the SINR can reflect interference with the wireless communication device. Therefore, receiver branches are further described herein. Receiver branches can be associated with at least one of a panel identifier (ID) and / or a CMR pair ID. In some embodiments, the reported SINR value can be determined based on (or according to) signals from antenna elements corresponding to all given receiver branches.
[0155] B.5.2 Resource Settings
[0156] For group-based reporting, signal power can be determined based on the first CMR. Noise and / or interference corresponding to the signal can be determined based on one or more second CMR / IM resources. The second CMR can be configured in the same CMR pair as the first CMR. Interference measurement (IM) resources can be associated with the first CMR, a CMR pair including the first CMR, and / or a first / second CMR configured in the same CMR pair. Therefore, further clarification may be required in the current specification.
[0157] For example,
[0158] ○ When two resource settings are configured, the IM resource can be associated with a measurement pair or with an SSB / NZP CSI-RS resource used for channel measurements in the same measurement pair.
[0159] ○ When a resource setting is configured, the CMR used for interference measurements can be configured in the same measurement pair of the SSB or NZP CSI-RS resources used for channel measurements.
[0160] C.5.3 Interference Measurement Resource Allocation
[0161] For group-based reporting, CSI-IM resource configurations can be specific to an SSB and / or NZP CSI-RS resource pair. Therefore, the RSs in the two resource settings do not need to be in a one-to-one correspondence, and the numbers can be different. Therefore, the current specification needs to be further described as follows:
[0162] ● For example, when two resource settings are configured, each SSB or NZP CSI-RS resource (or SSB / NZP CSI-RS resource pair) used for channel measurement is associated with one CSI-IM resource or one NZP CSI-RS resource used for interference measurement, based on the order of the SSB or NZP CSI-RS resource (or SSB / NZP CSI-RS resource pair) used for channel measurement and the CSI-IM resource or NZP CSI-RS resource used for interference measurement in the corresponding resource set.
[0163] VIII. Channel Measurement and Beam Management
[0164] Figure 20 A flowchart of method 2050 for channel measurement and beam management is shown. Method 2050 can be used in conjunction with the methods described herein. Figures 1 to 19 This can be implemented using any components and devices described in detail. In summary, method 2050 may include receiving a configuration that includes at least one CMR (252). Method 2050 may include performing a measurement of at least one CMR (254). Method 2050 may include sending a report (256).
[0165] Referring now to operation (252), in some embodiments, a wireless communication device (e.g., a UE) can receive / acquire / obtain configuration from a wireless communication node (e.g., a gNB). The wireless communication node can send / transmit / broadcast / transmit the configuration to the wireless communication device. This configuration may include at least one Channel Measurement Reference Signal (RS) resource (CMR) and / or other information. For example, the configuration may include / provide / specify / indicate at least one CMR and / or reporting instructions. In some embodiments, the wireless communication device can determine / configure / identify X sets of CMRs and / or X subsets of CMRs from a set of CMRs. The wireless communication device can determine the X sets and / or X subsets based on (or according to) this configuration. The parameter / number X can be an integer greater than 1 (or other value). In some embodiments, the wireless communication device can receive / acquire a message including a bitmap from the wireless communication node. In some embodiments, the wireless communication device can determine at least one CMR set from the X sets. The wireless communication device can determine at least one CMR set based on a bitmap. In some embodiments, each subset of the X subsets may have a corresponding / corresponding (1 / X)th resource from the resources of the CMR set. For example, resources from this set can be split / organized / divided / segmented into X parts. Each of the X parts can be used for each subset. A part can include or correspond to 1 / X of the resources. In some embodiments, a resource set can include M CMRs. When a resource set contains M CMRs, each (k+n*X)th CMR can belong to (or be associated with) the kth subset of the X subsets. In some embodiments, n can be an integer value that is at least zero and / or no greater than ((M / X)-1).
[0166] In some embodiments, the wireless communication device may determine / identify / configure a mapping. The wireless communication device may determine the mapping based on (or on) this configuration. The mapping may include or correspond to a mapping between a first group of CMRs and a second group of CMRs. Each group in the first and second groups may correspond to one (or be associated with) one of X sets and / or X subsets. In some embodiments, the configuration may include / provide / specify / indicate a first bitmap. The first bitmap may provide / indicate at least one CMR pair. A CMR pair may include a CMR from the first group and another CMR from the first and / or second group. The CMR pair may be used to determine / measure channel quality based on (or on) multiple CMRs (e.g., MTRP measurements). In some embodiments, the configuration may include / specify a second bitmap (e.g., for a single TRP transmission and / or measurement). The second bitmap may be used to indicate / specify / provide at least one CMR from the first and / or second group. At least one CMR from the first and / or second group may be used to determine / measure / identify channel quality based on (or on) a single CMR. For example, if a resource in the second bitmap is set / configured to "1" (or another value), that resource may be used for STRP measurements. In some embodiments, the CMR may not be indicated / specified for pairing by the first bit diagram. Each CMR not indicated for pairing by the first bit diagram can be used to determine channel quality based on (or on) a single CMR. For example, if a resource in the first bit diagram is set / configured to "0" (or another value), that resource can be used for STRP measurements. In some embodiments, each CMR from the first group and / or the second group can be used to determine / measure / identify channel quality. For example, all resources can be used for STRP measurements. Channel quality can be determined based on (or using) a single CMR.
[0167] In some embodiments, a first bitmap may indicate / specify / provide (e.g., for MTRP measurements) the number of CMR pairs. The number of CMR pairs can be configured based on (or based on) the capabilities of the wireless communication device. In some embodiments, a second bitmap may indicate / specify / provide (e.g., for STRP measurements) the number of CMRs. The number of CMRs can be configured based on (or based on) the capabilities of the wireless communication device. In some embodiments, multiple CMRs in a first group may be mapped to corresponding CMRs in a second group as CMR pairs for determining channel quality based on (or based on) multiple CMRs. In some embodiments, the number of multiple CMRs may be determined based on (or based on) mapping parameters and / or the number of CMRs in the first group and the number of CMs in the second group. In some embodiments, each CMR from the first group and the second group may be used to determine / measure / evaluate channel quality based on (or using) a single CMR. Each CMR to be used to determine channel quality (e.g., CMRs from the first group and the second group) may include all CMRs in the first group and the second group. Each CMR to be used to determine channel quality (e.g., CMRs from the first group and the second group) may include at least one CMR from the first group and / or the second group. At least one CMR can be demapped according to (or based on) mapping parameters. Each CMR to be used to determine channel quality (e.g., CMRs from the first and second groups) may include at least one CMR indicated / provided / specified by the second bitmap.
[0168] In some embodiments, the wireless communication device can determine / configure a corresponding number of CMRs in a first group. The corresponding number of CMRs (e.g., in the first group) can be mapped / associated / related with corresponding CMRs in a second group as CMR pairs. The wireless communication device can determine the corresponding number of CMRs to be mapped based on the number of CMRs configured in the first group. The wireless communication device can determine the corresponding number of CMRs to be mapped based on the number of CMRs configured by the wireless communication node in the second group. In some embodiments, the wireless communication device can receive / obtain mode parameters from the wireless communication node. The wireless communication device can receive mode parameters via higher-layer signaling (e.g., RRC signaling and / or MAC-CE signaling). The wireless communication device can receive mode parameters based on (or according to) its capabilities. In some embodiments, the wireless communication device can perform mapping / association of resources between the first group and / or the second group. The wireless communication device can perform mapping based on (or according to) the values of the mode parameters. In some embodiments, the values of the mode parameters can include or correspond to first values (e.g., Mode 1, "Enabled," and / or "On"). If the value of the mode parameter is the first value, then according to (or based on) claim 11, the wireless communication device can perform CMR mapping between the first group and / or the second group. For example, the wireless communication device can perform CMR mapping by determining the number of corresponding / corresponding CMRs in the first group to be mapped to CMR pairs with the corresponding / corresponding CMRs in the second group.
[0169] In some embodiments, the value of the mode parameter may include or correspond to a second value (e.g., mode 2, "disabled," and / or "off"). If the value of the mode parameter is a second value, the wireless communication device may perform / implement a mapping of CMRs between the first group and / or the second group. The wireless communication device may perform CMR mapping by mapping / associating every two (or other values) CMRs from different / separate / distinct groups. The wireless communication device may perform CMR mapping by mapping / associating every two (or other values) CMRs from different / separate / distinct groups and / or from the same / corresponding group. In some embodiments, multiple CMR resource pairs may share / use a common CMR. If multiple CMR resource pairs share a common CMR, other CMRs in the multiple CMR pairs may be configured to have the same quasi-co-address (QCL) type D and / or be quasi-co-addressed with QCL type D.
[0170] Referring now to operation (254), and in some embodiments, the wireless communication device may perform / implement / conduct at least one CMR measurement. The wireless communication device may perform the measurement according to (or based on) this configuration. In some embodiments, the CMR index having the maximum measured reference received power (RSRP) and / or signal-to-interference-plus-noise ratio (SINR) may be reported / specified / provided first in the report group that is reported first in the report group. In some embodiments, each CMR index may be determined / configured by the group index of its corresponding CMR group (e.g., configured via higher-layer signaling such as RRC signaling and / or MAC-CE signaling). In some embodiments, each CMR index may be determined / configured by its local group index within that corresponding CMR group. In some embodiments, the wireless communication device may send / transmit / transmit / broadcast N reports. The N reports may include N measurements with the best channel quality among all CMR pairs and / or individual CMRs. The N reports may include A measurements with the best channel quality among all CMR pairs. The N reports may include / contain B measurements with the best channel quality among all individual CMRs. The parameters / number / values A and B can each be positive integers, and A + B = N.
[0171] Referring now to operation (256), and in some embodiments, the wireless communication device may send / transmit / transmit a report / description. In response to the transmission of the report, the wireless communication node may receive / acquire the report. The report may include / provide / specify / indicate at least one of CMR index, channel quality, and / or other information. In some embodiments, channel quality may include at least one of Reference Signal Received Power (RSRP), Signal-to-Interference-plus-Noise Ratio (SINR), and / or Channel Quality Information (CQI). In some embodiments, the report may include / provide / specify measurement information (or other information). The measurement information may be used by the wireless communication node to configure subsequent transmissions. The measurement information may include / indicate / provide at least one of the following: the number of downlink or uplink layers, the number of Sound Reference Signal (SRS) ports, the panel identifier (ID) of the wireless communication device, and / or a situation index. In some embodiments, all possible combinations may be pre-configured by the wireless communication node and / or reported via the capabilities of the wireless communication device. If the wireless communication device reports / notifies / provides measurement results, only the situation index may be reported (e.g., via a report). The measurement information may specify / indicate whether multiple CMRs are shared and / or received / acquired using the same panel of the wireless communication device. If multiple CMRs share and / or receive the same panel using wireless communication devices, a group may include up to two layers. If multiple CMRs do not share and / or receive the same panel using wireless communication devices, a group may include up to four layers. In some embodiments, situation information (e.g., corresponding to (or associated with) a situation index) may be predefined / preconfigured by the wireless communication node. Situation information can be reported / transmitted through the capabilities of the wireless communication devices.
[0172] In some embodiments, in a first mode, the measurement information in the report may include information specific to each CMR in the report group. In some embodiments, in a second mode, the measurement information in the report may include information shared among all CMRs in the report group (e.g., the RI for each group). In some embodiments, in a second mode, the measurement information in the report may include information shared among all report groups (e.g., the RI is shared with all groups). In some embodiments, a wireless communication device may receive / acquire a message from a wireless communication node. The wireless communication device may receive the message based on (or according to) the capabilities of the wireless communication device (or other information). The message may be used to configure the wireless communication device to send / transmit / transmit a report (e.g., acquire a CMR pair) according to (or based on) the first mode and / or the second mode. In some embodiments, the report may include / provide / specify a flag value. The flag value may indicate whether the corresponding CMR in the report can be applied to uplink transmissions. For example, the flag value may include or correspond to a first value and / or a second value. If the flag value is set / configured to the first value, the corresponding CMR in the report can be applied to uplink transmissions. If the flag value is set / configured to the second value, the corresponding CMR in the report may not be applied to uplink transmissions. In another example, if the flag value is set / configured to the second value, the corresponding CMR can be applied to uplink transmissions. If the scheduling time of subsequent uplink transmissions exceeds a threshold, the corresponding CMR can be applied to the uplink transmission. The threshold can be configured based on (or according to) the capabilities of the wireless communication device.
[0173] In some embodiments, the first CMR (or other CMR) of each report group in the report can be applied to uplink transmissions. In some embodiments, a wireless communication node can use the first X CMRs of each report group to configure subsequent uplink transmissions. In some embodiments, a wireless communication node can use all CMRs of the first Y report groups in the report to configure subsequent uplink transmissions. Parameters X and / or Y can be positive integer values. In some embodiments, Radio Resource Control (RRC), Media Access Control (MAC CE) elements, and / or other signaling can be used to configure at least one of X or Y. In some embodiments, the report can include parameters. These parameters can indicate / specify / provide CMRs with maximum reference signal received power (RSRP) and / or signal-to-interference-plus-noise ratio (SINR) values. In some embodiments, the reported CMRs can be applied to uplink transmissions. Corresponding channel quality can be determined / measured / evaluated by (or based on) at least one of the following: downlink CMR transmission measurement, and / or uplink compensation following downlink CMR transmission measurement. In some embodiments, the CMR index can be determined by (or based on) a global index configured via higher-layer signaling (e.g., RRC and / or MAC-CE signaling). In some embodiments, the CMR index may be reported / provided / specified first in the reporting group that is first reported in the report. The CMR index may be determined / configured by its global index. Each remaining CMR index may be determined / configured by its local index within the corresponding CMR group (e.g., a first group and / or a second group configured by the wireless communication node). In some embodiments, the first CMR in each reporting group may come from the first group of CMRs. The second CMR in each reporting group may come from the second group of CMRs.
[0174] In the report, the index of the CMR used to determine / measure / acquire channel quality based on (or on) multiple CMRs can be determined / identified by the corresponding CMR pair index. In the report, the index of the CMR used to determine / measure / acquire / evaluate channel quality based on (or using) a single CMR can be determined / identified by a value unique relative to the CMR pair index. In some embodiments, the report may include / provide / specify / indicate the signal-to-interference-plus-noise ratio (SINR). The SINR can be determined based on (or on) signals from antenna elements corresponding to all receiver branches. Each receiver branch in the receiver branches can be associated / related to at least one of a panel identifier (ID) and / or a CMR pair ID. In some embodiments, the report may include / provide / specify / indicate the value of the SINR and / or the channel quality indicator (CQI). This value can be determined based on (or on) a first CMR. In some embodiments, the noise or interference corresponding to this value can be determined / measured / identified based on (or on) one or more second CMRs. One or more second CMRs can be configured in the same CMR pair of the first CMR. In some embodiments, noise and / or interference may be further determined / evaluated based on (or according to) one or more dedicated interference measurement (IM) resources. One or more dedicated IM resources may be associated with / correlated with a first CMR. One or more dedicated IM resources may be associated with / correlated with a CMR pair including the first CMR. In some embodiments, one or more dedicated IM resources may be associated with one or more second CMRs. One or more second CMRs may be configured in the same CMR pair as the first CMR.
