[Technical Field]

[0001] The present disclosure relates generally to wireless communications, including, but not limited to, systems and methods for channel measurement and beam management. [Background technology]

To facilitate the enablement of different data services and requirements, the elements of the 5GC, also called network functions, have been simplified; some of them are software-based and some are hardware-based, so that they can be adapted as needed. Summary of the Invention [Means for solving the problem]

[0003] The exemplary embodiments disclosed herein are intended to solve one or more problems associated with the prior art and to provide additional features that will become readily apparent from a review of the following detailed description in conjunction with the accompanying drawings. In accordance with various embodiments, exemplary systems, methods, devices, and computer program products are disclosed herein. However, these embodiments are presented by way of example, and not limitation, and it will be apparent to those skilled in the art upon reading this disclosure that various modifications to the disclosed embodiments can be made while remaining within the scope of the present disclosure.

In FIG. 1, the BS 102 and the UE 104 are contained within the respective geographic boundaries of the cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating in its assigned bandwidth to provide adequate wireless coverage to intended users.

[0025] For example, the BS 102 may operate within an assigned channel transmission bandwidth to provide adequate coverage to the UE 104. The BS 102 and the UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, the BS 102 and the UE 104 are generally described herein as non-limiting examples of "communication nodes" capable of implementing the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication in accordance with various embodiments of the present solution.

[0026] 2 illustrates a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. System 200 may include components and elements configured to support known or conventional operational features that need not be described in detail herein. In one exemplary embodiment, system 200 may be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment, such as wireless communication environment 100 of FIG. 1, as described above.

[0027] The system 200 generally includes a base station 202 (hereinafter "BS 202") and a user equipment device 204 (hereinafter "UE 204").

The operation of the two transceiver modules 210 and 230 may be coordinated in time such that the downlink transmitter is coupled to the downlink antenna 212 at the same time that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 may be coordinated in time such that the uplink transmitter is coupled to the uplink antenna 232 at the same time that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250. In some embodiments, there is a truncated time synchronization with a minimum guard time between changes in duplex direction.

[0030] The UE transceiver 230 and the base station transceiver 210 are configured to communicate over a wireless data communication link 250 and cooperate with appropriately configured RF antenna devices 212 / 232 capable of supporting a particular wireless communication protocol and modulation scheme.

Memory modules 216 and 234 may be realized as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, a hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art. In this regard, memory modules 216 and 234 may 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 may also be integrated into their respective processor modules 210 and 230. In some embodiments, memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during execution of instructions executed by processor modules 210 and 230, respectively. Each of the memory modules 216 and 234 may also include non-volatile memory for storing instructions executed by the processor modules 210 and 230, respectively.

For example, the network communications module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, without limitation, the network communications module 218 provides an 802.3 Ethernet interface to enable the base station transceiver 210 to communicate with conventional Ethernet-based computer networks. In this manner, the network communications module 218 may include a physical interface for connecting to a computer network (e.g., a mobile switching center (MSC)).

The model is divided into seven subcomponents or layers, each of which represents a conceptual collection of services provided to the layers above and below it. The OSI model also defines logical networks and effectively describes computer packet transfers through the use of different layer protocols. The OSI model is sometimes referred to as the seven-layer OSI model or seven-layer model. In some embodiments, the first layer may be the physical layer. In some embodiments, the second layer may be the medium access control (MAC) layer. In some embodiments, the third layer may be the radio link control (RLC) layer.

Systems and methods for enforcing resource configuration

[0036] In certain systems (e.g., 5G New Radio (NR), Next Generation (NG) systems, and / or other systems), multiple transmit and receive point (MTRP) technology may improve / enhance effective coverage at the edge of a cell and / or reduce the adverse impact of blocking effects. With the standardization of MTRP technology, procedures / techniques for enhancing downlink (DL) transmissions are gradually becoming stable. However, current procedures / techniques for enhancing uplink (UL) transmissions are not stable. In certain scenarios, wireless communication devices (e.g., UEs, terminals, and / or serving 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.

[0037] The system and method presented herein considers the multi-panel simultaneous transmission capability of a wireless communication device. Furthermore, the system and method include one or more grouping / pairing techniques for measurement reference signals (RS) on the wireless communication node side (e.g., a central processing unit (CPU), a ground terminal, a base station, a gNB, an eNB, a transmission and reception point (TRP), a network (NW), or a serving node), and a reporting format on the wireless communication device side (e.g., after receiving an instruction). Specifically, one or more of the following problems / challenges may be considered:

[0038] The wireless communication node may instruct / designate / notify / report (e.g., to a wireless communication device) measurement resources used for single transmit and receive point (STRP) transmissions, measurement resources used for MTRP transmissions, and / or resources that need to be simultaneously received by the wireless communication device. After receiving / obtaining an instruction from the wireless communication node, the wireless communication device may report / notify / provide measurement information. For example, the measurement information may include a measurement resource index, a measurement result, and / or other information.

[0039] The MTRP technique can effectively improve / enhance transmission throughput in certain systems (e.g., Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A), and / or New Radio Access Technologies (NR) in enhanced mobile broadband (eMBB) scenarios) by using multiple transmission and reception points (TRPs). Using MTRP transmission and / or reception can effectively reduce / reduce the probability of information jamming and / or improve / enhance transmission reliability in certain scenarios (e.g., Ultra-Reliable Low Latency Communications (URLLC) scenarios).

[0040] According to (or based on) the mapping / relationship / association between the transmitted signal flow and the multiple TRPs / panels, the multiple coordinated transmission / reception points can be divided / categorized / organized / classified into at least two types. The at least two types can include coherent transmission and / or unassociated transmission. In the case of coherent transmission, each data layer can be mapped to the multiple TRPs / panels via a weighted vector. However, coherent transmission may have higher / stricter requirements for synchronization between TRPs and / or the transmission capacity of the backhaul link. Furthermore, coherent transmission can be more sensitive to multiple non-ideal factors.

[0041] Non-coherent joint transmission (NCJT) may be less susceptible (or more susceptible) to the above factors. Therefore, NCJT may be used in certain systems (e.g., R15) to coordinate multiple transmission / reception points. In NCJT, each data flow can be mapped / associated with a port. A port may correspond to a TRP / panel with the same channel large-scale parameter (QCL). In some embodiments, different / separate / distinct data flows can be mapped to different ports with different large-scale parameters. Not all TRPs may be treated as virtual arrays.

[0042] In a particular system (e.g., Rel-17), one or more rules for CSI reporting in MTRP scenarios may be defined / configured. For CSI measurements associated with or related to reporting configurations for NCJT (e.g., CSI-ReportConfig and / or other configurations), a wireless communication device may 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 a CSI-RS resource set for channel measurement resources (CMRs). Each pair may be used for an NCJT measurement hypothesis. As shown in FIG. 3, a wireless communication device may be configured with at least two CMR groups, each having K1 and K2 CMRs, where Ks=K1+K2 CMRs. A CMR pair may be determined from the at least two CMR groups according to a detailed configuration method.

[0043] For beam measurements in multiple simultaneous MTRP transmissions, the wireless communication device may report / specify / indicate a single CSI report. The CSI report may include N beam pairs / groups and / or M (M>1) beams per pair / group. Different / separate / distinct beams in a pair / group may be received / acquired simultaneously.

[0044] In some embodiments, a beam may correspond to / refer to a quasi-co-location (QCL) state, a transmission configuration indicator (TCI) state, a spatial relationship state (or spatial relationship information state), a reference signal (RS), a spatial filter, and / or precoding. a) A transmit (Tx) beam may correspond to / refer to a QCL state, a TCI state, a spatial relationship state, a downlink / uplink (DL / UL) reference signal (e.g., a channel state information reference signal (CSI-RS), a synchronization signal block (SSB) (also called SS / PBCH), a demodulation reference signal (DMRS), a sounding reference signal (SRS), and / or a physical random access channel (PRACH)), a Tx spatial filter, and / or a Tx precoding. b) The receive (Rx) beam may correspond to / refer to a QCL state, a TCI state, a spatial relationship state, a spatial filter, an Rx spatial filter, and / or an Rx precoding. c) The beam identifier (ID) may correspond to / point to a QCL state index, a TCI state index, a spatial relationship state index, a reference signal index, a spatial filter index, a precoding index, and / or other indexes.

[0045] The spatial filter may correspond to the perspective of a wireless communication device and / or a wireless communication node. The spatial filter may refer to a spatial domain filter and / or other filters. The spatial relationship information may include one or more reference RSs. The spatial relationship information may be used to define / indicate / communicate / represent a spatial relationship between the target RS / channel and one or more reference RSs. The spatial relationship may refer to the same / quasi-simultaneous beam, the same / quasi-simultaneous spatial parameters, and / or the same / quasi-simultaneous spatial filter. The spatial relationship may include or correspond to a beam, a spatial parameter, and / or a spatial domain filter.

[0046] A QCL state may include one or more reference RSs and / or one or more corresponding QCL type parameters. The QCL type parameters may include at least one of Doppler spread, Doppler shift, delay spread, mean delay, mean gain, and / or spatial parameters (e.g., spatial Rx parameters). A TCI state may correspond to / refer to a QCL state. QCL Type A may include Doppler shift, Doppler spread, mean delay, and / or delay spread. QCL Type B may include Doppler shift and / or Doppler spread. QCL Type C may include Doppler shift and / or mean delay. QCL Type D may include spatial Rx parameters.

[0047] The UL signals may include a PRACH, a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), an UL DMRS, an SRS, and / or other channels / signals. The DL signals may include a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), SSB, a DL DMRS, a CSI-RS, and / or other channels / signals. The group-based reporting may include at least one of a beam group-based reporting and / or an antenna group-based reporting. A beam group may specify that different / separate / separate Tx beams in one group can be received and / or transmitted simultaneously. A beam group may indicate that Tx beams between different groups may not be received and / or transmitted simultaneously. A beam group may be described in terms of a wireless communication device.

[0048] The CMR may indicate / provide / specify channel measurement signals / resources. The signals / resources may include or correspond to CSI-RS, SS / PBCH blocks, and / or other signals / resources. The IMR may specify / indicate interference measurement (IM) signals / resources. The signals / resources may include or correspond to CSI-RS, CSI-IM, and / or other signals / resources. The Panel ID may include or correspond to the UE panel index. (I. Reporting of measurement results)

[0049] In some embodiments, the wireless communication device may send / transmit / communicate a report to the wireless communication node 102 or 202 in accordance with (or based on) at least one CMR. The at least one CMR may be configured by the wireless communication node. In some embodiments, the report may include: ●CMR index such as: One or more indices of CSI-RS, SS / PBCH blocks, and / or other signals / resources (e.g., SRS). ●Channel quality information such as: Reference Signal Received Power (RSRP). ○Signal to Interference and Noise Ratio (SINR). Channel Quality Information (CQI). In some embodiments, the reported parameters may depend on higher layer configuration. (II. CMR Set / Subset Configuration)

[0050] The wireless communication device 104 or 204 may measure / evaluate the channel according to (or based on) the CMR in the configured CMR resource set. To enhance / improve a particular approach using NCJT, one or more of the following schemes / options may be considered: Configure N CMR resource sets (e.g., N≧2) for the wireless communication device 104 or 204. Each resource set (or each resource group) may be associated with a wireless communication node (e.g., a TRP). o The number of resources in different / separate / distinct resource sets may be the same or different. • Split / categorize / classify / organize the resource set into N resource subsets (e.g., N≧2). Option 1: In some embodiments, M resources may be configured in a resource set. If M resources are configured in a resource set, the first M / N resources may belong to (or be included in) a first subset. The second M / N resources may belong to (or be part of) a second subset. Thus, the jth M / N resources may belong to the jth subset. Option 2: In some embodiments, M resources may be configured in a resource set. When there are M CMRs in a resource set, every (k+n*X) CMR belongs to (or is part of) the kth of the X subsets. The integer n may take integer values ​​at least 0 and / or less than or equal to ((M / X)-1). For example, M=6 (or other values) resources may be configured in a resource set. When M=6 resources are configured, the resource set may 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. In some implementations, more than one CMR set may be configured (e.g., aperiodic CSI resource configuration). When more than one CMR set is configured, one bitmap may be used to indicate / specify two or more sets corresponding to multiple TRPs from all configured sets. In the current specification, for aperiodic CSI resource configuration, the number of configured CSI-RS resource sets S can be greater than 1. For example, if S = 4, one bitmap can be used to select two of the four configured sets, each corresponding to two TRPs. (III. CMR Pair Configuration)

[0051] With respect to CSI reporting in NCJT scenarios, the CMR resources that the wireless communication node 102 or 202 instructs the wireless communication device 104 or 204 to receive (e.g., as a resource pair, independently and / or simultaneously) are described herein. Based on the description of the configuration of the CMR sets / subsets, the groups may include or correspond to the resource sets and / or resource subsets described above. Rule 1: The mapping between Group 0 (e.g., the first group) and Group 1 (e.g., the second group) may be performed / configured according to (or based on) a bitmap. The wireless communication node 102 or 202 may send / transmit / communicate information of the mapping to the wireless communication device 104 or 204. o 1.1: In some implementations, only one bitmap may be used to indicate the pairing / mapping. 1.1.1: A CMR pair may be determined from (or according to) at least two CMR groups (e.g., Group 0 and Group 1). FIG. 4 shows an example technique 400 for determining a CMR pair from two CMR groups. If a bitmap is set / configured to '1' (e.g., CMR3 and CMR1), the corresponding CMR pair may be used for MTRP measurements (e.g., to determine channel quality according to multiple CMRs in the CMR pair). If a CMR is set / configured to '0', the CMR may be used for STRP measurements (e.g., to determine channel quality according to a single CMR). In some implementations, all resources in Group 0 and / or Group 1 may be used for STRP measurements. 1.1.2: A CMR pair can be determined from (or according to) only one CMR group (e.g., Group 0 or Group 1). FIG. 5 shows an example technique 500 for determining a CMR pair from one CMR group and / or two CMR groups. If a bitmap is set / configured to '1', the corresponding CMR pair can be used for MTRP measurement (e.g., to determine channel quality according to multiple CMRs in the CMR pair). If a CMR is set / configured to '0', the CMR can be used for STRP measurement (e.g., to determine channel quality according to a single CMR). In some implementations, all resources in Group 0 and / or Group 1 can be used for STRP measurement. o 1.2: In some implementations, two bitmaps may be used to indicate / specify / configure pairing and / or STRP measurements, respectively. In some embodiments, the two bitmaps are not limited to two bitmaps, but may be two parts of one bitmap. 6 illustrates an example technique 600 for indicating a CMR pair. If a bitmap is set / configured to "1", the corresponding CMR pair can be used for MTRP measurements. 7 shows an example technique 700 for indicating STRP measurements. If a bitmap is set / configured to "1", the corresponding CMR can be used for STRP measurements. The number of CMR pairs (or CMRs) indicated / specified by the wireless communication node 102 or 202 and / or the number of single CMRs used for STRP measurements (e.g., the number of 1s in a bitmap) may depend on (or be configured accordingly with) the capabilities of the wireless communication device 104 or 204. ● Rule 2: Mapping of the first group (eg, group 0) and the second group (eg, group 1) in a given order. o 2.1: Configured by (or according to) wireless communication node 102 or 202. Group 0 may have M CMRs (e.g., CMR#1, CMR#2, . . ., CMR#M), and Group 1 may have N CMRs (e.g., CMR#1, CMR#2, . . ., CMR#N). The parameter S (e.g., S=0.5, 1, 2, . . .) may be configured by the wireless communication node 102 or 202. Multiple CMRs in the first group may be mapped / associated / related to respective CMRs in the second group in order (e.g., as CMR pairs for MTRP measurement). The parameter S may specify / indicate the number of CMRs in the first group to be mapped with CMRs in the second group. S=0.5 means that one CMR in the first group should be mapped to two CMRs in the second group. For example, if S=2, CMRs #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, CMRs #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)}. If M / N>2, the CMR that can be used for STRP measurement can be: Option 1: Remaining CMRs in Group 0 (e.g., if M=3 and N=1, one CMR remains in Group 0) Option 2: All CMRs (e.g., groups 0 and / or 1) Option 3: CMR shown by bitmap (see e.g. 1.2: STRP measurement instructions). If M / N<2, the CMR that can be used for STRP measurement can be: Option 1: Remaining CMR in Group 1 (or other groups) Option 2: All CMRs (e.g., groups 0 and / or 1) Option 3: CMR shown by bitmap (see e.g. 1.2: STRP measurement instructions) For M / N=2, the CMR that can be used for STRP measurements can be: Option 2: All CMRs (e.g., groups 0 and / or 1) Option 3: CMR shown by bitmap (see e.g. 1.2: STRP measurement instructions) 2.2: Use of predefined mapping (e.g., wireless communication node 102 or 202 may not configure mapping information) The wireless communication device may determine / configure a matching / mapping relationship according to (or based on) the number of CMRs configured in different / separate groups by the wireless communication node. For example, the wireless communication device 104 or 204 may determine, as a CMR pair, the number of CMRs in the first group to be mapped with each CMR in the second group according to the number of CMRs configured in the first group and the number of CMRs configured in the second group by the wireless communication node. For example, group 0 may have M CMRs (e.g., CMR#1, CMR#2, . . ., CMR#M), while group 1 may have N CMRs (e.g., CMR#1, CMR#2, . . ., CMR#N). If M / N=2, CMR#1 and CMR#2 in group 0 may be mapped to CMR#1 in group 1. Furthermore, CMR#3 and CMR#4 in group 0 may be mapped to CMR#2 in group 1. If M / N=1, CMR#1 in group 0 may be mapped to CMR#1 in group 1. Furthermore, CMR#2 in group 0 may be mapped to CMR#2 in group 1. o 2.3: Particular embodiments may use / include a matching mode (and / or mode parameter). For example, the wireless communication device 104 or 204 may receive a mode parameter from the wireless communication node 102 or 202 (e.g., according to the capabilities of the wireless communication device). Mode 1: The mode parameter can be configured as a first value (e.g., “enabled” and / or “on”) according to higher layer signaling (e.g., radio resource control (RRC) and / or medium access control-control element (MAC-CE) signaling). When the mode parameter is configured as the first value, pairing can be performed according to the systems and methods of 2.1 and / or 2.2. Mode 2: The mode parameter can be configured as a second value (e.g., "disabled" and / or "off") according to higher layer signaling (e.g., RRC and / or MAC-CE signaling). When the mode parameter is configured as a second value, every two 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. The configured / assembled CMR pairs can include: ● Option 1: CMR pairs from two CMR groups (e.g., different groups), e.g., {CMR#1, CMR#3} {CMR#2, CMR#3} {CMR#1, CMR#4} {CMR#2, CMR#4}. ● Option 2: CMR pairs from at least one of two (e.g., the same) CMR groups (e.g., from one or two 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}. If multiple CMR pairs share a common CMR, the other CMRs in the multiple CMR pairs must be configured in the same Quasi-Collocation (QCL) Type-D or quasi-collocated to a QCL Type-D. For example, a CMR pair may include {CMR#1, CMR#3} {CMR#2, CMR#3}, where CMR#3 is common between the pair. Thus, other CMRs (e.g., CMR#1 and / or CMR#2) may be configured with and / or QCL-ized by the same / corresponding QCL-Type-D. (IV. Channel Measurement and Beam Management)

[0052] To improve effective coverage at cell edges and reduce the adverse effects of blocking, MTRP technology has become an important technical method in 5G NR systems. With the gradual standardization of MTRP technology, downlink transmission enhancement has gradually stabilized, but uplink enhancement is far from satisfactory. In particular, when UEs have multi-panel transmission capabilities, CSI feedback solutions and group-based reporting in beam management should be further considered.

[0053] The embodiments described herein are based on the UE's ability to simultaneously transmit multiple panels. Instructing the wireless communication device 104 or 204 to provide a reference signal for measurement clarifies the parameter restrictions for configuring multiple measurement resource sets / subsets from the wireless communication node 102 or 202 and the parameter design of the configuration method for multiple sets / subsets.

[0054] 8 shows a flow diagram illustrating a method 800 performed by a wireless communication device 104 or 204 for channel measurement and beam management according to an exemplary embodiment of the present disclosure. Generally, the method 800 may include the wireless communication device 104 or 204 receiving a configuration of at least one radio resource control (RRC) parameter for X CMR resource sets or X CMR resource subsets of a CMR from a CMR resource set (step 802). The method 800 may include the wireless communication device 104 or 204 measuring channel quality for the X CMR resource sets or X CMR resource subsets in accordance with the configuration (step 804) and transmitting a report to the wireless communication node 102 or 202 (step 806). The parameter X may be an integer greater than 1. The report may include at least one of a CMR index or channel quality.

[0055] 9 shows a flow diagram illustrating a method 900 performed by a wireless communication node 102 or 202 for channel measurement and beam management according to an exemplary embodiment of the present disclosure. Generally, the method 900 may include the wireless communication node 102 or 202 configuring a configuration of at least one radio resource control (RRC) parameter for X CMR resource sets or X CMR resource subsets from a set of CMR resources (step 902). The method 900 may include the wireless communication node 102 or 202 transmitting to the wireless communication device 104 or 204 the configuration of at least RRC parameters for configuring the wireless communication device 104 or 204 for measurements on the at least one CMR resource corresponding to the X CMR resource sets or the X CMR resource subsets. The parameter X may be an integer greater than 1.

[0056] 8 and 9, a wireless communication node may generate a configuration of at least one RRC parameter (step 902) and send / transmit / broadcast / communicate the configuration to a wireless communication device 104 or 204 (step 904). The configuration may include an indication of X CMR resource sets or X CMR resource subsets and / or other information. For example, the configuration may include / provide / specify / indicate X CMR resource sets or X CMR resource subsets and / or reporting instructions. The wireless communication device 104 or 204 may receive / obtain / acquire the configuration from the wireless communication node 102 or 202 (step 802) and may determine / identify the X CMR resource sets or X CMR subsets of the CMR set according to the received configuration.

[0057] In some implementations, the wireless communication device 104 or 204 may receive / obtain a message comprising a bitmap from the wireless communication node 102 or 202. The wireless communication device 104 or 204 may determine at least one CMR set from the X CMR sets. The wireless communication device 104 or 204 may determine the at least one CMR set according to the bitmap. In some implementations, each of the X CMR subsets may have a respective / corresponding (1 / X)th resource from the set of CMRs. For example, resources from the set may be divided / organized / divided / partitioned into X portions. Each portion of the X portions may be related to or form a corresponding CMR subset. A portion may include or correspond to 1 / X of the resources. In some implementations, one resource set may include M CMRs. If there are M CMRs in a resource set, then every (k+n*X)th CMR may belong to (or be associated / related to) the kth CMR subset out of the X CMR subsets, where the integer n may take on an integer value at least 0 and / or less than or equal to ((M / X)-1).

[0058] The wireless communication device 104 or 204 may determine / identify / configure the mapping. The wireless communication device 104 or 204 may determine the mapping according to (or based on) a configuration received from the wireless communication node 102 or 202. The mapping may include or correspond to a mapping between a first group of CMRs and a second group of CMRs. Each of the first and second groups may correspond to (or be associated with) one of the X CMR sets and / or X CMR subsets. The configuration may include / provide / specify / indicate a first bitmap. The first bitmap may provide / indicate at least one CMR pair. The CMR pair may include a CMR from the first group and another CMR from the first and / or second group. The CMR pair can be used to determine / measure channel quality according to (or based on) multiple CMRs (e.g., MTRP measurements). In some implementations, 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 group and / or the second group. The at least one CMR from the first group and / or the second group can be used to determine / measure / identify channel quality according to (or based on) the single CMR. For example, if a resource in the second bitmap is set / configured as “1” (or other value), the resource can be used for STRP measurement. In some implementations, a CMR may not be indicated / specified by the first bitmap for pairing. Each CMR not indicated by the first bitmap for pairing can be used to determine channel quality according to (or based on) the single CMR. For example, if a resource in the first bitmap is set / configured as “0” (or other value), the resource can be used for STRP measurement.In some implementations, the CMRs from the first group and / or the second group may each be used to determine / measure / identify channel quality. For example, all resources may be used for STRP measurements. Channel quality may be determined according to (or using) a single CMR.

[0059] In some embodiments, the first bitmap may indicate / designate / provide several CMR pairs (e.g., for MTRP measurements). The number of CMR pairs may be configured according to (or based on) the capabilities of the wireless communication device. In some implementations, the second bitmap may indicate / designate / provide several CMRs (e.g., for STRP measurements). The number of CMRSs may be configured according to (or based on) the capabilities of the wireless communication device. In some implementations, multiple CMRs in the first group can be mapped to respective CMRs in the second group in order as CMR pairs for determining channel quality according to (or based on) the multiple CMRs. In some implementations, the number of multiple CMRs can be determined according to (or based on) a mapping parameter and / or the number of CMRs in the first group and the number of CMRs in the second group. In some implementations, CMRs from the first and second groups can each be used to determine / measure / assess channel quality according to (or by using) a single CMR. The CMRs (e.g., from the first and second groups) each to be used to determine channel quality may include all CMRs in the first and second groups. The CMRs (e.g., from the first and second groups) each to be used to determine channel quality may include at least one CMR in the first group and / or the second group. At least one CMR may not be mapped according to (or based on) the mapping parameters. The CMRs (e.g., from the first and second groups) each to be used to determine channel quality may include at least one CMR indicated / provided / specified by the second bitmap.

[0060] In some implementations, the wireless communication device 104 or 204 may determine / configure the respective numbers of CMRs in the first group. Each number of CMRs (e.g., in the first group) may be mapped / associated / related to each CMR in the second group as a CMR pair. The wireless communication device 104 or 204 may determine the respective numbers of CMRs to be mapped according to the number of CMRs configured in the first group. The wireless communication device 104 or 204 may determine the respective numbers of CMRs to be mapped according to the number of CMRs configured in the second group by the wireless communication node 102 or 202. In some implementations, the wireless communication device 104 or 204 may receive / obtain mode parameters from the wireless communication node 102 or 202. The wireless communication device 104 or 204 may receive the mode parameters via higher layer signaling (e.g., RRC signaling and / or MAC-CE signaling). The wireless communication device 104 or 204 may receive the mode parameter according to (or based on) the capabilities of the wireless communication device 104 or 204. In some implementations, the wireless communication device 104 or 204 may perform resource mapping / association between the first group and / or the second group. The wireless communication device 104 or 204 may perform the mapping according to (or based on) the value of the mode parameter. In some implementations, the value of the mode parameter may include or correspond to a first value (e.g., mode 1, “enabled,” and / or “on”). When the value of the mode parameter is the first value, the wireless communication device 104 or 204 may perform CMR mapping between the first group and the second group according to (or based on) claim 11. For example, the wireless communication device 104 or 204 may perform CMR mapping by determining a respective / corresponding number of CMRs in the first group to be mapped with a respective / corresponding CMR in the second group as a CMR pair.

[0061] In some implementations, the value of the mode parameter may include or correspond to a second value (e.g., mode 2, “disabled,” and / or “off”). When the value of the mode parameter is the second value, the wireless communication device 104 or 204 may implement / perform CMR mapping between the first group and / or the second group.

The wireless communication device 104 or 204 may perform CMR mapping by mapping / associating every two (or other values) CMRs from different / separate / distinct groups and / or the same / corresponding groups. In some implementations, multiple CMR pairs of resources may share / use a common CMR. When multiple CMR pairs of resources share a common CMR, the other CMRs in the multiple CMR pairs may be configured in and / or quasi-colocated with the same quasi-colocated (QCL) Type-D.

[0062] The wireless communication device 104 or 204 may perform / implement / take measurements of at least one CMR of the X CMR set or XMR subset. The wireless communication device 104 or 204 may perform the measurements according to (or based on) a configuration. In some implementations, the CMR index with the highest measured reference signal received power (RSRP) and / or signal-to-interference-and-noise ratio (SINR) may be reported / specified / provided first in the first-reported reporting group in a report. In some implementations, each CMR index may be determined / configured by the group index of its corresponding group of CMRs (e.g., configured via higher layer signaling, such as RRC signaling and / or MAC-CE signaling). In some implementations, each CMR index may be determined / configured by its local index within the corresponding group of CMRs. In some implementations, the wireless communication device 104 or 204 may send / transmit / communicate / broadcast N reports. The N reports may include N measurements with best channel quality among all CMR pairs and / or a single CMR. The N reports may include A measurements with best channel quality among all CMR pairs. The N reports may comprise / include B measurements with best channel quality among all single CMRs. The parameters / numbers / values ​​A and B may each be positive integer values, where A+B=N.

[0063] The wireless communication device 104 or 204 may send / transmit / communicate a report / description. In response to sending the report, the wireless communication node 102 or 202 may receive / obtain a report.

The measurement information may include / indicate / provide at least one of a number of downlink or uplink layers, a number of Sounding Reference Signal (SRS) ports, a panel identifier (ID) of the wireless communication device, and / or a case index. In some implementations, all possible combinations can be pre-configured by the wireless communication node 102 or 202 and / or reported via the capabilities of the wireless communication device. When the wireless communication device 104 or 204 reports / notifies / provides measurement results, only the case index may be reported (e.g., via a report). The measurement information may specify / indicate whether multiple CMRs are shared with and / or received / acquired from the same panel of the wireless communication device. If multiple CMRs are shared and / or received on the same panel of the wireless communication device, a group may include up to two layers. If multiple CMRs are not shared and / or received on the same panel of the wireless communication device 104 or 204, a group may include up to four layers. In some implementations, case information (e.g., corresponding to or associated with a case index) may be pre-defined / pre-configured by the wireless communication node. The case information may be reported / communicated via the capabilities of the wireless communication device 104 or 204. (Support for multiple CMR resource sets / subsets)

[0064] In some network systems, the wireless communication device 104 or 204 measures the channel according to the RS in the configured CSI-RS resource set. To enhance the application of the NCJT scenario, the network or wireless communication node 102 or 202 can (i) configure N (N≧2) CMR resource sets for the wireless communication device 104 or 204, where each CMR resource set can be associated with a corresponding TRP, or (ii) divide the resource set into N (N≧2) CMR resource subsets. Further enhancement of the NCJT scenario requires further reconsideration of this set / subset configuration. Referring to FIG. 3, the resource configuration can be determined by the higher layer parameter CSI-ResourceConfig. Furthermore, the resource set configuration can be determined by the parameter NZP-CSI-RS-ResourceSet. The configuration can include at least one of a repetition parameter, an aperiodic triggering offset (aperiodicTriggeringOffset) parameter, and / or a tracking reference signal information (Trs-info) parameter. Configuring multiple CMR resource sets / subsets in one resource configuration / resource set requires reconsideration of at least the repetition parameter, the aperiodic triggering offset parameter, and / or the tracking reference signal information (Trs-info) parameter. The configuration of CMR resources can be determined by the parameter NZP-CSI-RS-Resource. The configuration can include a periodicity and offset parameter that defines the CMR periodicity and slot offset for periodic / semi-persistent CSI-RS. All CMRs from the X CMR resource sets or X CMR resource subsets can be configured with the same periodicity, while the slot offsets can be the same or different for different CMR resources.

[0065] With respect to the parameter repetition, if the corresponding field (in the configuration received by the UE) is set to off or is absent, the wireless communication device 104 or 204 may not assume that the NZP-CSI-RS resources in a CMR resource set are transmitted with the same downlink spatial domain transmit filter. The parameter repetition for each CMR resource set / subset can be set to the same or different values.

[0066] With respect to the aperiodicTriggeringOffset parameter, the wireless communication node 102 or 202 may transmit an offset q between the slot containing the DCI that triggers the set of aperiodic NZP CSI-RS resources and the slot in which the CSI-RS resources are configured for the wireless communication device 104 or 204. In an SDCI-based MTRP scenario, a different offset should be configured for each set / subset to avoid collisions. For an MDCI-based MTRP scenario, the aperiodicTriggeringOffset parameter can be the same or different across different CMR resource sets / subsets.

[0067] The Trs-Info parameter may indicate that the antenna ports of all NZP-CSI-RS resources in a CSI-RS resource set are the same. The parameter Trs-Info may be the same or different across CMR resource sets / subsets. In the configuration examples below, the nzp-CSI-RS-ResourceSetList may contain or reference configuration parameters for multiple CMR resource sets / subsets. The dashed box below represents a group of configuration parameters for a single CMR resource set / subset, while the nzp-CSI-RS-ResourceSetList may contain or reference multiple groups of configuration parameters for multiple CMR resource sets / subsets. [Table 1] (configuring parameters for various CMR resource sets / subsets)

[0068] A wireless communication node may support or use one or more methods / processes for configuring parameters of CMR resource sets / subsets. According to a first configuration method / process, the wireless communication node 102 or 202, or the network, may configure a separate / corresponding set of RRC parameters for each CMR resource set / subset and send / transmit / communicate / broadcast the configured set of RRC parameters to the wireless communication device 104 or 204. Thus, the wireless communication device 104 or 204 may receive a separate set of configuration parameters or a separate set of RRC parameters (e.g., denoted NZP-CSI-RS-ResourceSet) for each of the X CMR resource sets or X CMR resource subsets.

[0069] For example, the network, or wireless communication node 102 or 202, may configure / define the following set of configuration / RRC parameters: Set 1 [Table 2-1] Set 2 [Table 2-2]

[0070] As can be seen from the above example, all parameters (nzp-CSI-ResourceSetId, nzp-CSI-RS-Resources, repetition, aperiodicTriggeringOffset, Trs-Info) are configured / indicated under each set according to corresponding requirements, regardless of whether their values ​​are the same or different across different CMR resource sets / subsets. Generally, regardless of the configuration method / process used, the configuration received by the wireless communication device 104 or 204 may include multiple configuration parameters, each parameter for or corresponding to one or more of the X CMR resource sets or X CMR resource subsets. Each of the multiple parameters may be set to the same value across various CMR resource sets / subsets (e.g., across the X CMR resource sets / subsets). In some implementations, each (or at least one) of the multiple parameters may be set to different values ​​across different CMR resource sets and / or CMR resource subsets.

[0071] According to a second configuration method / process, the wireless communication node 102 or 202, or the network, can configure configuration / RRC parameters that have the same values ​​across various CMR resource sets / subsets in a single configuration / RRC parameter set and can configure configuration / RRC parameters that have different values ​​across various CMR resource sets / subsets in each configuration / RRC parameter set. The wireless communication node 102 or 202 can associate these sets of configuration / RRC parameters (or refer to a set that includes parameters that have the same values ​​across various CMR resource sets), for example, by a parameter denoted as Setassociation-r17. As an example, the wireless communication node 102 or 202 can configure / define the following sets of configuration / RRC parameters (corresponding to different CMR resource sets) and send / transmit / broadcast / communicate them to the wireless communication device 104 or 204: Set 1 [Table 3-1] Set 2 [Table 3-2]

[0072] As shown in the example above, one group of parameters (repetition and Trs-Info) is not configured in set 1 and not configured in set 2 because these parameters have the same values ​​(or are configured in the same way) in both sets. Groups of parameters can be shared across other sets of parameters (e.g., set 2) by referencing set 1 in which they are included / indicated. Other parameters (those configured differently across various CMR resource sets) can only apply to the corresponding CMR resource set / subset.

[0073] If the wireless communication device 104 or 204 is configured with multiple CMR resource sets / subsets, when the wireless communication device 104 or 204 finds that some parameters are missing in a given configuration / RRC parameter set (e.g., Set 2), the wireless communication device 104 or 204 can search for the missing parameters in another configuration / RRC parameter set (e.g., Set 1). The wireless communication device 104 or 204 can identify the other set of configuration / RRC parameters (e.g., Set 1) as a set associated with the high-level parameter SetAssociation-r17. Specifically, a configuration / RRC parameter set in which some parameters are missing can include the parameter SetAssociation-r17 that indicates (references or points to) the set of configuration / RRC parameters in which the missing parameters can be found / obtained. This approach makes it possible to avoid or at least mitigate / reduce redundant transmission of the same information between the wireless communication node 102 or 202 and the wireless communication device 104 or 204, thus resulting in more efficient use of bandwidth.

[0074] According to a second configuration method / process, the wireless communication device 104 or 204 may receive a first set of RRC parameters associated with a first one of the X CMR resource sets or a first one of the X CMR resource subsets to be applied to at least one of the X CMR resource sets or the X CMR resource subsets, and may receive, for each of the X CMR resource sets or the X CMR resource subsets, a second set of RRC parameters to be applied to the corresponding CMR resource set or the corresponding CMR resource subset. The first set of RRC parameters may refer to parameters having the same values ​​across the various CMR resource sets / subsets, and the second set of RRC parameters may refer to parameters having different values ​​across the various CMR resource sets / subsets. The wireless communication device 104 or 204 may receive a reference parameter to indicate one or more values ​​of the first set of RRC parameters to be applied to the X CMR resource sets or the X CMR resource subsets.

[0075] A third configuration method / process relates to the case where all configuration / RRC parameters are the same across all X CMR sets / subsets. According to a first approach of the third configuration method / process, the wireless communication node 102 or 202 may configure / define a single configuration / RRC parameter set (for all X CMR resource sets / subsets) that includes parameters that directly divide resources into CMR resource sets / subsets. The parameters may indicate how the CMR resources are divided / distributed among the various CMR resource sets / subsets. For example, the wireless communication node 102 or 202 may configure / define a single set of configuration / RRC parameters as follows: Set 1 [Table 4]

[0076] A resource partitioning parameter can be used to indicate whether to partition CMR resources into subsets. The resource partitioning parameter may indicate whether to partition CMR resources into subsets. If set to on, the wireless communication device 104 or 204 can partition CMR resources into X CMR resource sets / subsets according to a default method. For example, the first half belongs to a first set CMR resource set / subset, and the second half belongs to a second CMR resource set. More generally, the wireless communication device 104 or 204 can partition / divide CMR resources according to any predefined default method (e.g., into any predefined number of CMR resource sets / subsets). If the parameter is set to off or not present, it is the same as 3GPP Release 16.

[0077] The resource partitioning mode parameter can be used to indicate a resource partitioning mode or method among multiple partitioning modes / methods. For example, if it is set to 0, the first half of the resources can belong to a first CMR resource set / subset, and the remaining half can belong to a second CMR resource set / subset (assuming a total of two CMR resource sets / subsets). If it is set to 1, resources with odd indices can belong to the first CMR resource set / subset, and resources with even indices can belong to the second set / subset (assuming a total of two CMR resource sets / subsets). It should be noted that these example modes are provided for illustrative purposes, and the wireless communication node 102 or 202 can configure / set / define different modes and / or a different total number (e.g., X) of CMR resource sets / subsets.

[0078] A wireless communication node 102 or 202 may use / configure only one or both of the resource partitioning parameter and the resource partitioning mode parameter. If both parameters are used, defined, or configured, the wireless communication node 102 or 202 may use them in a non-conflicting manner.

[0079] According to a second approach of the third configuration method / process, the wireless communication node 102 or 202 may configure / define a single configuration / RRC parameter set (for all X CMR resource sets / subsets) that includes parameters that directly configure the different resource subsets. For example, the wireless communication node 102 or 202 may configure the set of configuration / RRC parameters as follows: [Table 5]

[0080] The nzp-CSI-RS-Resources parameter can be used to configure the CMR resources for the first subset, and the nzp-CSI-RS-Resources-r17 parameter can be used to configure the CMR resources for the second subset. Other parameters can apply to both subsets. According to this second approach of the third configuration method process, the wireless communication device 104 or 204 can receive X CMR resource lists, each of the X CMR resource lists corresponding to a CMR resource subset. For each CMR resource list of the X CMR resource lists, the wireless communication device 104 or 204 can receive a corresponding parameter indicating the CMR resource list. For example, the wireless communication node 102 or 202 may configure various parameters such as nzp-CSI-RS-Resource-r17-1, nzp-CSI-RS-Resource-r17-2, ..., nzp-CSI-RS-Resource-r17-(n-1) to indicate n-1 additional CMR resource subsets (e.g., in addition to the first CMR resource subset). (Selection of CMR resource set / subset for beam or channel measurements)

[0081] For aperiodic CSI-RS resource configuration, the wireless communication node 104 or 204 may configure a CMR resource set (or multiple periodic / semi-persistent resource sets) with S > 2. The wireless communication device 104 or 204 may use a selection method (e.g., among multiple selection methods) to select the CMR resource set to be used for beam or channel quality measurements.

[0082] According to a first selection method / process / approach (referred to as the RRC configuration approach), the wireless communication node 102 or 202 may configure RRC parameters under a set of CMR resources to indicate whether the set is used for CMR pair selection (providing one CMR for the CMR pair). Another set of CMR resources may provide another CMR to form a CMR pair. For example, the wireless communication node 102 or 202 may configure the RRC parameters as follows: [Table 6]

[0083] The groupBasedBeamMeasurement parameter, for example, when set to on, can indicate that the corresponding CMR resource set / subset should provide CMR to the CMR pair. The wireless communication device 104 or 204 can use RRC signaling (e.g., the groupBasedBeamMeasurement parameter) to select X CMR resource sets / subsets from the Y CMR resource sets / subsets, where Y is an integer greater than X. The groupBasedBeamMeasurement parameter may simply notify or indicate to the wireless communication device 104 or 204 that the corresponding set / subset has been selected to provide CMR to the CMR pair. The wireless communication device 104 or 204 can be further notified / informed of resources from the CMR resource set / subset according to one or more rules (e.g., as described with respect to FIGS. 4-7) to form CMR pairs with other resources from another selected CMR resource set / subset.

[0084] According to a first selection method / process / approach (referred to as bitmap dynamic selection), the wireless communication node 102 or 202 may configure and transmit (e.g., in a DCI) a bitmap to indicate two or more sets from all configured sets for CMR pair selection (e.g., as described above with respect to FIGS. 4-7) to the wireless communication device 104 or 204. The wireless communication device 104 or 204 may use the bitmap received from the wireless communication node 102 or 202 to select X CMR resource sets / subsets from Y CMR resource sets / subsets, where Y is an integer greater than X.

[0085] In a third selection method / process / approach, referred to herein as RRC and bitmap selection, the wireless communication node 102 or 202 may use one or more RRC parameters to configure several CMR resource sets that can be used to select a CMR pair and may use a bitmap to indicate selection from among the configured CMR resource sets via the RRC parameters. The wireless communication device 104 or 204 may first select Z CMR resource sets / subsets from the Y CMR resource sets / subsets using RRC signaling (e.g., a groupBasedBeamMeasurement parameter), where Y is an integer greater than Z. The wireless communication device 104 or 204 may then select X CMR resource sets / subsets from the Z CMR resource sets / subsets using a bitmap received from the wireless communication node 102 or 202, where Z is an integer greater than X. (Beam damage recovery)

[0086] In a cell, if the wireless communication device 104 or 204 calculates / determines link quality based on a beam failure detection reference signal resource set (BFD-RS set) that is worse than a predetermined threshold, the wireless communication device 104 or 204 can record the event as a beam failure instance. When the wireless communication device 104 or 204 detects that the number of beam failure instances is equal to or greater than a corresponding threshold, the wireless communication device 104 or 204 can confirm beam failure in the cell. This cell can be referred to as a failed cell. If the failed cell is configured for one link, the wireless communication device 104 or 204 can confirm beam failure for that link, and the link can be referred to as a failed link.

[0087] When the wireless communication device 104 or 204 detects a beam failure, the wireless communication device 104 or 204 attempts to find a new beam from a new candidate beam indicator reference signal resource set (NBI-RS set) that has a corresponding L1-RSRP measurement value that is equal to or greater than a predetermined threshold. For beam failure recovery, after the wireless communication device 104 or 204 receives a response from the wireless communication node 102 or 202 within a certain period, the wireless communication device 104 or 204 can apply the new beam for PDCCH monitoring or PUCCH transmission.

[0088] In some network systems, the period for applying a new beam to a signal of a single TRP (link) can be 28 symbols from the last symbol of a PDCCH reception having a DCI format that schedules a PUSCH transmission with the same HARQ process number as for the first PUSCH transmission and a toggled NDI field value. The period of 28 symbols can be based on the minimum SCS of the responding receiving cell and the failed cell. The above-described approach addresses beam failure recovery for a single TRP (link). In the case of MTRP, beam failure recovery is more complicated, and the above approach is not operational. For example, if there are two or more failed TRPs (links), some failed cells may be associated with a first TRP (link) and some other failed cells may be associated with a second TRP (link). In such a case, the wireless communication device 104 or 204 would not know how to calculate / determine the 28 symbols (or, in general, the period to wait before applying a new beam). According to an example implementation, the wireless communication device 104 or 204 can determine the 28 symbols according to one of the following options: Option 1: Determining the SCS of the 28 symbols is per failed cell / group of failed cells for all failed TRPs (links) (i.e. based on the minimum SCS of the responding received cells and the respective failed cells). Option 2: Determining the SCS of the 28 symbol is based on the smallest SCS of the responding received cells and on all failed cells / cell groups of all failed TRPs (links). Option 3: Determining the SCS of the 28 symbols is based on the smallest SCS of the responding received cells and all the failed cells / cell groups per failed TRP (link)

[0089] With respect to MTRP, a TRP (link) can be implemented / defined / configured according to one of the following options: - Option 1: Different values ​​for the CORESET pool index. -Option 2: Different BFD-RS / NBI-RS sets. - Option 3: By different TRP-ID.

[0090] 10 shows a flowchart illustrating a method 1000 for beam failure recovery according to an exemplary embodiment of the present disclosure. Generally, the method 1000 may include the wireless communication device 104 or 204 applying a new beam to a signal 28 symbols after the last symbol of a physical downlink control channel (PDCCH) reception according to a responding receiving cell and a minimum subcarrier spacing of at least a first cell (step 1002).

[0091] In some implementations, the at least first cell may include at least one of each or all of the failed cells. The wireless communication device may determine the at least first cell as a failed cell by detecting one or more beam failures, each detected based on a beam failure detection reference signal resource set (BFD-RS set) configured on the cell for the link. All of the failed cells may be associated with the same link. The link may include at least one of a CORESET pool index, a transmission and reception point (TRP), a beam failure detection reference signal resource set (BFD-RS set), or a TRP-ID.

[0092] In some implementations, the new beam may include a reference signal (RS) from a new candidate beam indicator reference signal resource set (NBI-RS set) that has a corresponding link quality above a threshold. The signal may include at least one of a PDCCH monitoring that uses the same antenna port quasi-co-location parameters as the RS, or a PUCCH transmission that uses the same spatial domain filter as the RS.
