Description

Beam Management and Resource ConfigurationsFIELD

[0001] Various example embodiments relate to the field of wireless communication and, in particular to beam management and / or resource configurations.BACKGROUND

[0002] In the field of wireless communication, different frameworks and / or configurations, for example related to Channel State Information (CSI), Synchronization Signals (SS), e.g. Synchronization Signal Blocks (SSB) and / or Sounding Reference Signals (SRS), exist which are currently tied to a particular carrier, e.g. Component Carrier (CC), and / or a particular bandwidth part (BWP). Among other things, this may require transmitting or signaling one or more of such configurations separately or individually, e.g. for each carrier and / or BWP. This may even occur, for example, in cases where resources overlap, e.g. in the time domain and / or frequency domain. This may result in a duplicated configuration being configured to an apparatus, e.g. a User Equipment (UE), which may result in additional overhead. It may be beneficial, e.g. among other things, to provide at least one improved framework and / or configuration to address, among others, the aforementioned drawbacks. In addition or alternatively thereto, it may be beneficial to improve an associated signaling, to reduce redundancy and / or to reduce signaling overhead. In addition or alternatively thereto, it may be beneficial, e.g. among other things, to improve a capability of the UE, in particular for multiple carriers.SUMMARY

[0234] Reference will now be made in detail to the various embodiments, one or more examples of which are illustrated in the figures. Within the following description of the drawings, the same reference numbers may refer to same components. Generally, only the differences with respect to individual embodiments may be described. Each example may be provided by way of explanation and is not meant as a limitation. Further, features illustrated or described as part of one embodiment can be used on or in conjunction with other embodiments to yield yet a further embodiment. It is intended that the description includes such modifications and variations.

[0235] The drawings are schematic drawings which are not drawn to scale. Some elements in the drawings may have dimensions which are exaggerated for the purpose of highlighting aspects of the present disclosure and / or for the sake of clarity of presentation.

[0236] The subject-matter described herein relates to a novel approach, signaling and / or framework to improve and / or optimize configuration and / or reporting mechanisms, in particular in a multi-carrier scenario and / or a single carrier scenario, for, in particular Channel State Information (CSI), Sounding Reference Signal (SRS), and / or Synchronization Signal(s), such as Synchronization Signal Block(s) (SSB) and / or SSB resource(s) in wireless networks, particularly in the context of future sixth generation (6G) technologies.

[0237] A Channel State Information (CSI) framework or CSI resource framework may enable the network to gather detailed insights about, e.g. the channel conditions from an apparatus, e.g. a UE. The CSI framework may be designed with an intention of facilitating efficient and / or accurate reporting of channel condition(s), e.g. to enable optimal link adaptation and / or beam management. For example, this may assist in beammanagement, e.g. by aligning beams between base stations (e.g., gNBs) and UEs, in particular for optimal signal quality; link adaptation, e.g. by adjusting transmission parameters, such as related to modulation and / or coding; resource management, e.g. efficient scheduling and / or interference mitigation etc.

[0238] The CSI framework may comprise multiple components, including CSI-RS and CSI-IM resources, which may be used to measure and report various channel characteristic(s). CSI-RS reference signals transmitted by the base station may allow the UE to estimate the channel quality, while CSI-IM resources may help in measuring interference levels.

[0239] However, the current or existing framework(s) have several challenges. For example, current or existing framework(s) may require repetitive signaling. In particular, CSI- resources such as CSI-RS and / or CSI-IM, SRS, and / or SSB may be configured separately, in particular for each BWP or carrier, e.g. CC, even when the same resources overlap in time domain and / or frequency domain. This results in the same CSI resource being configured to UEs by the network (NW, e.g., gNB) multiple times, in particular via CSI-ResourceConfig, e.g. tagged to different bandwidth parts. In addition or alternatively, the (resource) configuration(s) may be specific for, associated with and / or tied / tagged to a particular carrier or CC and / or a particular bandwidth or BWP. This may tie, for example, a resource configuration with the CC and the BWP within CC. The aforementioned challenges may i) cause additional signaling overhead, ii) cause additional memory burden, e.g. for the UE, e.g. storing repetitive / redundant information, in particular for multiple carriers and / BWPs may increases memory usage, iii) create redundancy (e.g. redundant information), e.g. to be signaled and / or stored, and / or iv) affect a UE Capability Limitation, e.g. as UEs may have limited capacity to handle multiple CSI resources and / or redundant configuration, which may further strain their capability.

[0240] In a non-limiting example of a current / existing framework, e.g. in 5G or New Radio (NR), the CSI-ResouceConfig information element (IE) can provide the NZP-CSI-RS-ResourceSetld IE or CSI-SSB-ResourceSetld IE. Further the NZP-CSI-RS-ResourceSetld IE may point to the NZP-CSI-RS-Resource configuration, which along with other CSI-RS parameters may also provide the time domain resources and / or frequency domain resources occupied by the CSI-RS resources. This may tie / tag the resourceconfiguration with the CC and the BWP within the CC. As one possible and non-limiting example, a 4 times 8-port CSI-RS resource configuration may be used for periodic reporting for a base station (e.g., the gNB) with 8 transmit antenna ports. This may occupy 4 NZP-CSI-RS resources and 1 resource set. The UE’s CSI-RS resource capability may be exhausted very soon, in particular when configuring multiple component carriers, that are not even activated for the data transmission, as the UEs support a limited number of NZP-CSI-RS measurement resources and / or cannot be configured with a larger number than their supported capability. Thus, the current / existing 5G framework may require to signal CSI resource configuration for each bandwidth part separately even when the mentioned resources overlap in time domain or the frequency domain or both. This may result in the same CSI resource being configured to UEs by the NW multiple times via CSI-ResourceConfig tagged to different bandwidth parts causing additional signaling overhead and memory burden. Similar challenges are encountered also with the SRS and / or SSB configurations. For example, the IE CSI-SSB-ResourceSetld used for any L1 reporting, may contain only the SSB-lndex. The SSB-ARFCN configuration(s) may be specific to the carrier. This creates good amount of redundant information stored at the UE.

[0241] However, the subject-matter described herein intends to address and / or at least partially reduce / improve one or more of these challenges i)-iv). In particular, it was noticed that much of the signaling overhead could be reduced and / or the UE capability improved, e.g. for multiple carriers, if the framework allows less redundancy. The framework suggested herein may be designed / constructed to do so, e.g. aiming for a leaner structure. The new mechanism described herein may be designed to, e.g. reduce signaling overhead and / or enhance a UE capability by organizing resources into pools as described herein.

[0242] "Channel State Information" or CSI may refer to the information about a state, condition and / or status of a channel, in particular that an apparatus, e.g. a UE, may report, e.g. to the network or network device (e.g. gNB in 5G). CSI may provide insights into the quality of a channel, e.g. enabling the network to optimize data transmission (e.g., selecting the best modulation scheme, power control, beamforming, and / or MIMO techniques etc.). The CSI framework may include a configuration of CSI reporting, e.g. the types of CSI that can be reported, and / or the condition(s) under which these reports maybe generated. The specifications may detail the coding and / or structure of the CSI reports. The specifications may also outline the interactions between the CSI reporting and / or the scheduling of resources. A CSI reporting framework may allow the UE to send channel quality feedback. CSI reporting framework may support multiple reporting modes, in particular including one or more of: a i) periodic reporting mode, e.g. sending reports at fixed and / or regular / continuous (time) intervals, e.g. with a defined periodicity or a certain (time) slots, e.g. allowing for substantially constant / recurring feedback, ii) a semi-persistent reporting mode, e.g. CSI reports may be sent at predefined intervals, but the reporting instances can be activated or deactivated, e.g. by the network device, as needed, which may reduce unnecessary reports, and / or iii) an aperiodic reporting mode, e.g. CSI reports may be sent only when (explicitly) requested by the network device, e.g. it may dynamically trigger a CSI report whenever needed. The CSI reporting framework may allow the network to balance the trade-off between reporting overhead and / or the need for timely channel state information. Periodic reporting may be used for scenarios where the channel conditions are relatively stable, while aperiodic reporting may be triggered by specific events and / or conditions that may require, in particular immediate attention. The CSI reports can include a variety of types, (reporting) quantities and / or metrics such as: a CQI, which may represent or be associated with a MCS that can be used; a PMI, which may suggests and / or be associated with precoding matrix, andRI, which may indicate a number of data streams (or layers) that can be supported. The CSI reports may provide detailed insights into the channel characteristics and / or (optimal) transmission parameters. The framework may specify how CSI is to be reported and / or utilized, in particular to optimize a performance of a radio access network (RAN). It may include mechanisms for the apparatus, e.g. the UE, to report channel conditions, which are useful for adaptive modulation and / or coding, as well as for beamforming techniques that improve signal quality and / or coverage.

[0243] The CSI resource framework described herein may be designed with the intention of facilitating efficient and / or accurate reporting of channel conditions, e.g. to enable optimal link adaptation and / or beam management as mentioned above. The framework may comprise multiple components, including i) CSI-RS or CSI-RS resources and / or CSI-IM or CSI-IM resources, which may be used to measure and / or report various channel characteristics. CSI-RS may be a type of RS transmitted by the network device, e.g. a base station, which may allow the UE to estimate and / or measure a channel quality.CSI-IM may help in measuring interference levels, e.g. unlike CSI-RS, which may measure overall channel quality, CSI-IM may be dedicated to evaluating / measuring interference levels, e.g. from neighboring cells or beams.

[0244] A "Synchronization Signal Block", "synchronization signal / PBCH block" or "SSB" may be regarded as a component or signaling or, it may be at least part of a signaling, that may be used in wireless communication, such as for example 5G or NR, to facilitate a synchronization or synchronization process between the apparatus, e.g. the UE, and a base station, e.g. of a network. The SSB may provide signals, channels and / or information that enable the device to, in particular initially, connect and / or stay synchronized with the base station, allowing it, for example, to communicate effectively over the network. The at least one SSB may be part of a signaling in which a plurality of SSBs are transmitted, e.g. one after another, successively, consecutively and / or periodically. For example, the signaling may include at least a first SSB and at least a second SSB, which for example may be transmitted (e.g. timely) after the first SSB. This may be also referred to as a sequence or series of SSBs. It may be possible to have SSBs transmitted in different modes, e.g. an always-on mode, where the base station e.g. continuously transmits SSBs, e.g. at a periodic interval, or an on-demand mode, e.g. where the base station transmits SSBs only when needed.

[0245] "Sounding Reference Signal(s)" (SRS) may be regarded as an uplink reference signal, in particular transmitted by the apparatus, e.g. the UE, to a base station. It may assist the base station in understanding how well the apparatus, e.g. the UE, can transmit data over different frequencies. SRS may be used for uplink channel sounding, where the UE transmits a SRS and the base station measures it. This process helps the network to estimate the uplink channel quality and / or perform tasks such as link adaptation, scheduling, and / or beamforming (directly) for uplink transmissions, and / or using the Downlink (DL)ZUplink (UL) reciprocity also for downlink transmissions.

[0246] As mentioned above, the subject-matter described herein addresses one or more of the above challenges i)-iv) (or even further challenges) by organizing, structuring, dividing, managing, categorizing, arranging, combining, joining, bundling, pooling and / or gathering resources into one or more "pool(s)" which may be referred to as "resource pool(s)" or "resource pool configuration(s)" (these terms may be used interchangeablyherein). In other words, a resource pool configuration may be regarded as a collection, set, group, pool, list or conglomeration / agglomeration of different resources (or templates as described herein) which may be arranged based on shared, common and / or similar characteristics / properties. The resource pool configuration may be regarded as a "library" of resources or resource configurations, e.g. that can be accessed and / or used, in particular dynamically, rather than assigning each resource individually, or statically as in existing frameworks / solutions.

[0247] The resource pool configuration may include one or more "templates" or "resource configuration templates" (these terms may be used interchangeably herein). A "template" may be referred to as a predefined and / or reusable configuration or resource configuration, e.g. for specific resources as mentioned herein, e.g. CSI (RS / IM), Synchronization Signals, e.g. SSBs orSSB-like Synchronization Signals, SRS etc., which may define or indicate how a resource / resource configuration is to be structured and / or used. A "template" may be referred to as a mask, blueprint and / or model (these terms may be used interchangeably herein). The template(s) may indicate a resource pattern and / or, optionally, a report format, wherein it is possible / conceivable to configure the report format separately to the apparatus, e.g. the UE. It should be noted that since the resource pool configuration includes one or more templates as described herein, a feature, step and / or function or the like mentioned specifically for the resource pool configuration may similarly or correspondingly apply also to the one or more template(s), or vice versa.

[0248] As mentioned above, in current or existing frameworks, the resource configuration, e.g. CSI Resource configuration, may be specific for and / or tied / tagged to a particular carrier or component carrier and / or a particular BWP. In contrast thereto, the framework described herein may correspond to a template-based and / or pool-based framework / approach, in which the templates may not be tied or tagged to a specific CC or BWP. Instead, they may be designed for general use, e.g. across multiple carriers or frequency ranges. Usage of a resource pool configuration and / or the templates grouped therein may reduce and / or eliminate the need to repeatedly configure the same resources for different carriers or BWPs. To this end, the templates may be "carrier-agnostic" and / or at least bandwidth agnostic, e.g. within a carrier, which may mean that the same template can be applied across multiple carriers or BWPs. In particular, it is proposed to construct and / or signal the CSI-RS / CSI-IM / SSB (orSSB-like Synchronization Signal) / SRS resourceallocation as a pool per carrier or per group of carriers, in particular without the resources being tagged, linked to and / or associated with a particular, designated and / or specific BWP or carrier. This may be achieved, as described herein, by creating and / or arranging the resources in carrier-agnostic and / or BWP-agnostic pools, in particular based on the carrier / propagation properties, and / or by creating common templates, e.g. for each type of resource(s).

[0249] Usage of the resource pool configuration and / or the templates may enable that, in particular overlapping, resources are signaled (only) once, e.g. reducing redundancy. By consolidating resources into templates and / or pools respectively, the UE may manage a smaller number of unique configurations, in particular freeing up its capacity for additional carriers and / or measurements. Resources signaled as pools of templates may reduce signaling overhead and / or may eliminate / reduce the need to transmit repetitive resource information, which may reduce the signaling and / or a structure of the signaling. Furthermore, the resource pool configuration and / or the templates may be flexible and / or reusable, e.g. which may reduce the need for static and / or repetitive configuration, in particular allowing more dynamic and / or scalable (e.g. templates may adapt easily / fast to new scenarios) resource management. Also, UE capabilities may be improved, e.g. as templates may allow UEs to support more carriers and / or measurements, e.g. due to reduced redundancy. This reduced signaling / structure may save memory and / or computational burdens for both the network and UE(s).

[0250] A non-limiting example of a resource pool configuration, which may be carrieragnostic and / or at least bandwidth agnostic within a carrier, may include one or more of the following:a) a plurality of CSI resource configurationtemplates, which may include at least one of: CSI-RSresource configuration templates, or CSI-IM resource configuration templates;b) a plurality of CSI reporting configuration templates;c) a plurality of Synchronization Signal resource configuration templates;d) a plurality of SRS resource configuration templates, or other / further templates.

[0251] When reference is made to the resource pool configuration including "at least" one of the above a)-d), it may mean that the resource pool configuration may include at least one or multiple, e.g. a combination of these. As mentioned above, one or more of the templates a)-d) are usable or reusable across at least one of: multiple BWPs, or multiple carriers within a specific frequency band or a plurality of frequency bands.

[0252] The resource pool configuration, in particular the respective templates included therein may be organized, structured, divided, categorized, arranged, combined, joined, bundled, pooled and / or gathered (these terms may be used interchangeably herein) based on carrier properties / characteristics and / or propagation properties / characteristics or the like.

[0253] For example, resource pool configuration, in particular the one or more of the templates a)-d) mentioned above may be pooled based on at least one of: i) at least one frequency range (FR), or ii) at least one duplexing method. The at least one duplexing method includes at least one of: TDD or FDD. A frequency range may refer to a specific frequency band, e.g. in Hz, e.g. MHz / GHz etc., wherein there may be a first FR, e.g. FR1, a second FR, e.g. FR2 and so on. TDD may refer to a mode of spectrum operation, e.g. where the same frequency band is used for both uplink and downlink communication, wherein the two directions are separated in time; while FDD may use separate frequency bands for uplink and downlink. An example resource pool configuration may therefore be referred to as "FR1-TDD", which may indicate a group of TDD-configured frequencies or channels within the first frequency range or FR1 range.

[0254] According to subject-matter described herein, the templates may include at least a plurality of CSI resource configuration templates, for example CSI-RS resource configuration templates and / or CSI-IM resource configuration templates. Optionally, the CSI resource configuration templates may include a plurality of CSI reporting configuration templates. The plurality of CSI resource configuration templates may be pooled in the at least one resource pool configuration based at least in part on at least one of: i) antenna configuration, ii) an antenna dimension, or iii) antenna port(s).The antenna configuration may refer to how antennas are arranged and / or used in a wireless system, e.g. Multiple-Input, Multiple-Output (MIMO), for example in a format representing Transmitters (Tx) (number of transmitting antennas) and Receivers (Rx) (number of receiving antennas), in a grid-like structure or an (antenna) array, such as Txx Rx, e.g. 2x2 MIMO, 4x4 MIMO, 8x8 MIMO etc.The antenna dimension may refer to the physical size and / or structure, e.g. of the antenna array used in the network. It may include a number of elements, antenna spacing, e.g. distance between antenna elements, array geometry and / or a size of rows / columns of the antenna elements.The antenna port(s) may refer to a, in particular logical, abstraction of an antenna or set of antennas that transmit or receive signals in a specific manner. For example, multiple physical antennas may be mapped to / associated with a single port using beamforming and / or one, in particular physical, antenna may serve multiple logical ports, e.g. in different polarizations. For example, a 2-port system may support dualpolarized antennas (e.g., ±45° polarization) and / or an 8-port, 16-port, 32-port systems may be used for more spatial streams, e.g. beamforming.

[0255] The plurality of CSI reporting configuration templates may be pooled in the at least one resource pool configuration based at least in part on at least one of:- at least one reporting mode, including a periodic or an aperiodic reporting mode (reference may be made to the above in this respect); or- at least one reporting quantity.The at least one reporting quantity may indicate at least one of: at least i) CQI, ii) PMI, or iii) Rl.The CQI may represent how good or bad the radio channel is, e.g. at a given time. A higher CQI may mean better channel quality, higher modulation (e.g. 256-QAM) and / or higher data rates, while a lower CQI may mean a poorer channel Quality, lower modulation (e.g. QPSK) etc.The PMI may provide information about the precoding matrix to use, e.g. for MIMO transmissions. Precoding may be regarded as a technique that optimizes spatial multiplexing and / or beamforming, e.g. to improve data rates and / or reliability. PMI may indicate preferred antenna weighting (e.g. precoding matrix) for transmitting signals.The Rl may represent the number of independent spatial streams that the channel can support for MIMO transmission, e.g. R=1 low rank, e.g. 1 stream; R=2, 3 or 4, e.g. multiple parallel streams.The at least one reporting quantity may indicate at least one of: i), ii) or iii) with at least one associated codebook type, e.g. Type I Codebook or Type 2 Codebook, wherein the latter may be for advanced beamforming support.

[0256] According to subject-matter described herein, which may be combined with the above examples and / or any example mentioned herein, the templates may include at least a plurality of Synchronization Signal resource configuration templates, for example SSB configuration templates or SSB-like Synchronization Signal templates. Optionally, the CSI resource configuration templates may include a plurality of CSI reporting configuration templates. The plurality of Synchronization Signal resource configuration templates may be pooled in the at least one resource pool configuration based at least in part on a transmission characteristic. The transmission characteristic includes information (or parameters) indicative of at least one of:i) a number of SSB(s) (e.g. as described above), which may refer to SSB(s) transmitted on a, in particular different, frequency location, e.g. in on a wide network carrier. In such a case, the SSB beam patterns may resemble each other.;ii) a number of beams within an SSB burst, in particular each SSB may be transmitted over multiple beams, e.g. to improve coverage and / or signal strength;iii) a number of SSB bursts, which may refer to how many SSB bursts occur in a given time period, time window and / or time slot. More bursts may mean higher frequency of synchronization opportunities for UEs;iv) a periodicity of transmission, which may refer to how often SSB bursts may be transmitted; and / orv) a transmission scheduling, which may define when and / or how SSB bursts may be transmitted relative to other transmissions.

[0257] The plurality of Synchronization Signal resource configuration templates may be pooled in the at least one resource pool configuration based at least in part on a beam index, which may be regarded as an identifier, e.g. assigned to a specific beam transmitted by a base station.

[0258] The plurality of CSI reporting configuration templates may be pooled in the at least one resource pool configuration based at least in part on at least one of:- at least one reporting mode, including a periodic or an aperiodic reporting mode (reference may be made to the above in this respect);- a RSRP, which may measure the received power level of the RS, e.g. . - a RSRQ, which may measure a signal quality by considering both RSRP and total received power (RSSI).- a SI NR, which may measure the ratio of desired signal power to interference + noise; and / or- a beam reporting.

[0259] According to subject-matter described herein, which may be combined with any one of the above examples and / or any example mentioned herein, the templates may include at least plurality of SRS resource configuration templates. The plurality of SRS resource configuration templates may be pooled in the at least one resource pool configuration based at least in part on at least one of: an antenna configuration or an antenna dimension (reference may be made to the above in this respect). The plurality of SRS resource configuration templates may be pooled in the at least one resource pool configuration based at least in part on at least one of: a number of antenna ports (reference may be made to the above in this respect), or an uplink transmission bandwidth. The uplink transmission bandwidth includes at least one of: at least one wide-band transmission, or at least one sub-band transmission.

[0260] The resource pool configuration which may include the one or more templates as described may be provided by the network or network device to the apparatus (e.g., the UE). In addition, the network device may provide at least one "carrier-specific" configuration, which may be in particular assigned to the apparatus. To this end, the apparatus may perform the step of: receiving at least one carrier-specific configuration assigned to the apparatus, in particular after receiving the at least one resource pool configuration. A "carrier-specific configuration" may be regarded as a set of parameters, e.g. provided by the network device to the apparatus, e.g. the UE, that specifies how the UE should handle radio resources, measurements, and / or reporting for a particular, specific, designated and / or selected carrier or CC and / or BWP.

[0261] The carrier-specific configuration (which may in addition or alternatively also referred to as a BWP-specific configuration) may specify how resources from the pool should be used, e.g. for a particular carrier. The carrier-specific configuration may include one or more UE-specific parameter(s). For example, the carrier-specific configuration may include at least one template ID, which may also be referred to as a linkage or mapping, in particular with / to at least one, e.g. active, carrier. In particular, the at least one template ID may specify, define and / or indicate which template is to be used by the apparatus, e.g. for at least one, e.g. active, carrier. The carrier-specific configuration may be a per carrier (e.g. perCC) configuration, which may include, as mentioned, a template mapping, BWP configuration, time domain parameters, e.g. for CSI reporting, etc. In other words, the carrier-specific configuration may comprise a list of templates, e.g. referred to by the template I D(s), to be used by the UE or that the UE shall use, for e.g. CSI / SSB (or SSB-like) / SRS resources and / or for measurement reporting.

[0262] The carrier-specific configuration may include at least one indication. The indication may be a flag or pointer which is included or encoded in carrier-specific configuration, e.g. using one or more bit(s). It may be conceivable to transmit the indication separately from / to the carrier-specific configuration. The indication may be referred to as a first indication, e.g. with respect to another indication received from the network device and / or provided to the network device. The indication may be at least one indication (or more) or the indication may correspond to a single indication having multiple parts. In other words, there may be a first indication or at least a first part of the indication indicating a first information, and a second indication or second part of the indication indicating a second information. The first and second information may be related to and / or associated with the carrier-specific configuration described herein. The indication may be an explicit indication, e.g. (directly) included in the carrier-specific configuration, e.g. directly readable by the apparatus. The indication may be an implicit indication, e.g. derivable from the carrier-specific configuration itself, e.g. the apparatus, e.g. the UE, may conclude to the indication based on the carrier-specific configuration. In both cases, however, it may be said that the carrier-specific configuration indicates or is indicative of certain information, in particular at least one template of the at least one resource pool configuration to be applied to at least one carrier.

[0263] "based at least in part on the indication" may, for example, mean based on one or more part(s) of the indication. In other cases, it may mean, for example, based on the indication, e.g. as a whole, but also based on additional information and / or additional information element(s), parameters or data. Likewise, "determining at least one resource, e.g. a CSI resource, in particular to be measured, based at least in part on carrier-specific configuration" may for example mean based on i) the at least one (explicit) indication (or at least a part thereof) or based on the carrier-specific configuration itself (i mplicitly / i mplicit indication), and / or ii) based on the template(s). The indication or the at least one carrierspecific configuration may indicate at least one template (e.g. depending on the specific embodiment, e.g. at least one CSI resource / reporting template / Synchronization Signal resource configuration template / SRS template) of the at least one resource pool configuration to be applied to at least one, in particular active, carrier. The at least one resource to be measured / applied may be determined by applying at least one of the plurality of templates (e.g. depending on the specific embodiment, e.g. at least one CSI resource / reporting template / Synchronization Signal resource configuration template / SRS template) to at least one, in particular active, carrier.

[0264] The at least one indication may link, map, assign, allocate associate and / or connect at least one of the plurality of resource configuration templates to at least one, in particular active, carrier of the at least one carrier-specific configuration. For example, the at least one indication may link at least one of: i) at least one the plurality of CSI resource configuration templates, ii) at least one of a plurality of CSI reporting configuration templates, or iii) at least one the plurality of Synchronization Signal resource configuration templates etc. to at least one, in particular active, carrier of the at least one carrier-specific configuration.

[0265] The resource to be determined from the template may be a carrier-specific resource, e.g. specific to / for a particular carrier or bandwidth. For example, according to subject-matter described herein, at least one CSI resource to be measured may be determined based at least in part on the plurality of CSI resource configuration templates, in particular by applying at least one of the plurality of CSI resource configuration templates to at least one, in particular active, carrier. The CSI resource to be measured may be specific to at least one, in particular active, carrier. The CSI-resource may include a CSI-RS and / or a CSI-IM. For example, according to subject-matter described herein, atleast one Synchronization Signal to be applied may be determined based on the plurality of Synchronization Signal resource configuration templates in particular by applying at least one of the plurality of Synchronization Signal resource configuration templates to at least one, in particular active, carrier. The at least one Synchronization Signal to be applied may be specific to at least one, in particular active, carrier. The Synchronization Signal may include at least one SSB or it may include at least one SSB-like Synchronization Signal. For example, according to subject-matter described herein, at least one SRS resource to be applied may be determined based at least in part on the plurality of SRS resource configuration templates, in particular by applying at least one of the plurality of SRS resource configuration templates to at least one, in particular active, carrier. The at least one SRS resource to be applied may be specific to at least one, in particular active, carrier. In addition and optionally, the at least one CSI reporting, CSI reporting resource or CSI reporting quantity (these terms may be used interchangeably herein), may be determined based at least in part on at least one carrier-specific configuration assigned to the apparatus and the plurality of CSI reporting configuration templates. The at least one CSI reporting may be specific to at least one, in particular active, carrier.

[0266] The apparatus may receive, from the network device, at least one indication (e.g. in addition to the indication included in the carrier-specific indication; it may be referred to as a second indication; or it may be another part of the indication mentioned above) that indicates activation at least one of: i) at least one CSI resource, or ii) a CSI reporting, on at least one active or inactive carrier. Based at least in part on the at least one indication, the apparatus may be further caused to at least perform: determining at least one of:i) at least one CSI resource to be measured from at least one of the plurality of CSI resource configuration templates, orii) at least one CSI reporting to be applied from at least one of the plurality of CSI reporting configuration templates. The inactive carrier may be a carrier in a deactivated state or a dormant state, e.g. a carrier that is not (yet) activated.

[0267] This may be achieved by different exemplary and non-limiting variants. In particular by: i) an, in particular explicit and / or aperiodic, CSI request that, for example also triggers the activation of the resource for an inactive (e.g. deactivated or dormant) carrier and / or by: ii) a separate mode for an inactive (e.g. deactivated or dormant) carrier,for example where at least some of the CSI measurements are still being made. The mode selection may be explicit, in particular either to the component carrier, or to the CSI resource or report configuration. For example, activating / deactivating of semi-persistent CSI reporting could be seen as such a mode change.

[0268] According to subject-matter herein, the apparatus may transmit SRS to the network device based on a time-hop occasion indicated by the SRS resource. In particular, this may indicate a time slot when the SRS transmission should occur. "Time-hopping" may be regarded as a technique used to spread the transmission, e.g. of SRS signals, across different time slots, in particular to avoid interference and / or make better use of the available spectrum. Instead of sending the SRS at fixed intervals, the UE may hop between different time slots, for example according to a pattern. A "Time-Hop Occasion" may refer to a specific time slot or time period, in which the SRS transmission is scheduled to occur. The time-hop occasion may be defined by the SRS resource configuration and / or can vary based on network conditions and / or UE configurations. The UE may transmit the SRS at the indicated time (e.g. as determined by the time-hop occasion). If the time-hop occasion aligns with an active part of the bandwidth (e.g. active BWP), the UE may transmit the SRS in that time slot. An active BWP may refer to a portion of the frequency range that the UE is currently operating on or using for its transmission(s). If the time-hop occasion (in particular the scheduled time for SRS transmission) falls outside the active BWP (e.g., the time-hop occasion is not in the portion of the frequency spectrum the UE is currently operating on), then the UE may avoid, omit and / or pause transmission of the SRS forthat time-hop occasion. This may avoid wasting resources by transmitting an SRS when it's not within the active bandwidth that the UE is using.

[0269] The term "non-transitory," as used herein, is a limitation of the medium itself (i.e., tangible, not a signal) as opposed to a limitation on data storage persistency (e.g., RAM vs. ROM).

[0270] As used herein, "at least one of the following: " and "at least one of " and similar wording, where the list of two or more elements are joined by "and" or "or", mean at least any one of the elements, or at least any two or more of the elements, or at least all the elements. Likewise, a slash" / ", as used herein, for example in connection with "and" / "or" as (e.g., "a and / or b") may mean: - a (alone), - b (alone), - both a and b. The same may apply for "a / b".

[0271] The apparatus may include a processor configured to provide signals to and receive signals and to control the functioning of the apparatus. The processor may be configured to control other elements of apparatus by effecting control signaling via electrical leads connecting processor to the other elements, such as a display or a memory. The processor may, for example, be embodied in a variety of ways including circuitry, at least one processing core, one or more microprocessors with accompanying digital signal processor(s), one or more processor(s) without an accompanying digital signal processor, one or more coprocessors, one or more multi-core processors, one or more controllers, processing circuitry, one or more computers, various other processing elements including integrated circuits (for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), and / or the like), or some combination thereof.

[0272] The term "circuitry" may refer to one or more or all of the following:(a) hardware-only circuit implementations (such as implementations in only analog and / or digital circuitry) and(b) combinations of hardware circuits and software, such as (as applicable): (i) a combination of analog and / or digital hardware circuit(s) with software / firmware and(ii) any portions of hardware processor(s) with software (including digital signal processor(s)), software, and memory(ies) that work together to cause an apparatus, such as a mobile phone or server, to perform various functions) andhardware circuit(s) and / or processor(s), such as a microprocessor(s) or a portion of a microprocessor(s), that requires software (e.g., firmware) for operation, but the software may not be present when it is not needed for operation.

[0273] This definition of circuitry applies to all uses of this term in this application, including in any claims. As a further example, as used in this application, the term circuitry also covers an implementation of merely a hardware circuit or processor (or multiple processors) or portion of a hardware circuit or processor and its (or their) accompanying software and / or firmware. The term circuitry also covers, for example and if applicable tothe particular claim element, a baseband integrated circuit or processor integrated circuit for a mobile device or a similar integrated circuit in server, a cellular network device, or other computing or network device.

[0274] The apparatus may comprise memory which may store information elements. The apparatus may include volatile memory and / or non-volatile memory. For example, volatile memory may include Random Access Memory (RAM) including dynamic and / or static RAM, on-chip or off-chip cache memory, and / or the like. Non-volatile memory, which may be embedded and / or removable, may include, for example, read-only memory, flash memory, magnetic storage devices, for example, hard disks, floppy disk drives, magnetic tape, optical disc drives and / or media, non-volatile random access memory (NVRAM), and / or the like. Like volatile memory, non-volatile memory may include a cache area for temporary storage of data. At least part of the volatile and / or non-volatile memory may be embedded in processor. The memories may store one or more software programs, instructions, pieces of information, data, and / or the like which may be used by the apparatus for performing operations disclosed herein.

[0275] The apparatus may be a User Equipment (UE), for example a mobile or handled device, for example a mobile phone or a smart phone, or may be at least comprised in a UE.

[0276] Fig. 1 shows a CSI resource allocation for multiple, in particular overlapping BWPs (cf. Bandwidth Parts 140, including the multiple, at least partially overlapping, BWPs 100, 110, 120, 130). As can be seen, the CSI configuration may span over a (wide) bandwidth, and the CSI resource elements that are used for measurement may be those that fall within the bandwidth the UE is currently operating on (e.g. an active bandwidth part). For the beam management and / or channel sounding resources, the UE may derive the time resources and / or frequency resources to measure that conforms with the active bandwidth of the active carrier. As mentioned above, current or existing framework(s), e.g. in 5G, have several challenges (s. challenges i)-iv) above), which may require repetitive signaling. In particular, CSI- resources may be configured separately, in particular for each BWP or carrier, e.g. CC, even when the same resources overlap in time domain and / or frequency domain. This may result in the same CSI resource being configured to UEs bythe network device multiple times, in particular via a CSI-ResourceConfig IE, e.g. tagged to different bandwidth parts causing additional signaling overhead and memory burden.

[0277] The subject-matter described herein intends to address one or more of these challenges i)-iv). In particular, it was noticed that much of the signaling overhead could be reduced and / or the UE capability improved, e.g. for multiple carriers, if the framework allows less redundancy. The framework suggested herein may be designed / constructed to do so, e.g. aiming for a leaner structure. The new mechanism may be designed to, e.g. reduce signaling overhead and / or enhance a UE capability by organizing resources into pools and / or by using the templates as described herein.

[0278] Figs. 2 and 3 show example resource pool configurations according to subjectmatter described herein. It should be noted that the resource pool configurations as shown in Figs. 2-3 are purely exemplarily, in particular non-limiting with respect to their content, e.g. the specific templates and / or the specific resources / parameters mentioned / defined therein. Other / further resource pool configurations, templates and / or resources / parameters may be possible, e.g. as addition / alternative, and / or conceivable.

[0279] Fig. 2 shows a resource pool configuration, in particular a "Frequency Range 1, Frequency Division Duplex" (FRI-FDD)-resource pool which may comprise two CSI-RS resource configuration templates, such as 4-port CSI-RS resource configuration template (CSI-RS template #1), and a 8-port CSI-RS resource configuration template (CSI-RS template #2), which are carrier-agnostic and / or at least bandwidth agnostic within a carrier, in particular which could be used across multiple BWPs and / or CCs of a particular frequency band or a group of bands (for example the CSI-RS resource pool could be common for FR1-FDD bands). Similarly, the SSB resources for the FR1-TDD-pool could contain one template such as the 4-beam configuration (e.g., SyncSignal template, Synchronization Signal resource configuration template or SSB template #2) which is carrier-agnostic and / or at least bandwidth agnostic within a carrier, in particular which could be used across multiple BWPs and / or CCs of a particular frequency band or a group of bands. The CSI reporting configuration could also be arranged as pool of templates based on the carrier / propagation properties. For example, one CSI report template for FR1-FDD-pool could contain settings for periodic reporting with codeBookType-1, wideband-CQI-RI-PMI (CSI report template #1), another CSI reporttemplate could contain settings for aperiodic reporting with codeBookType-1, sub-band-CQI-RI-PMI (CSI report template #2) and another CSI reporting template could contain settings for periodic reporting and Synchronization Signal (SS)-RSRP (CSI reporting template #3).

[0280] Fig. 3 shows a resource pool configuration, in particular a "Frequency Range 1, Time Division Duplex" (FRI-TDD)-resource pool which may comprise two CSI-RS resource configuration templates, such as 8-port CSI-RS resource configuration template (CSI-RS template #1), and a 32-port CSI-RS resource configuration template (CSI-RS template #2), which are carrier-agnostic and / or at least bandwidth agnostic within a carrier, in particular which could be used across multiple BWPs and / or CCs of a particular frequency band or a group of bands. The FR1-TDD-resource pool configuration may comprise two CSI-IM resource configuration templates, such as a CSI-IM resource configuration template for pattern #0 (CSI-IM template #1) and a CSI-IM resource configuration template for pattern #1 (CSI-IM template #2), which are carrier-agnostic and / or at least bandwidth agnostic within a carrier, in particular which could be used across multiple BWPs and / or CCs. Similarly, the SSB resources for the FR1-TDD-resource pool could contain one template such as the 4-beam configuration (Synchronization Signal "SyncSignal" template or SSB (or SSB-like) template #1) and a 8-beam configuration (Synchronization Signal "SyncSignal" template or SSB (or SSB-like) template #2) which are carrier-agnostic and / or at least bandwidth agnostic within a carrier, in particular which could be used across multiple BWPs and / or CCs of a particular frequency band ora group of bands. The FR1-TDD-resource pool configuration may comprise two SRS resource configuration templates, such as an SRS resource configuration template for 1-port and wide-band (SRS resource configuration template #1) and an SRS resource configuration template for 4-ports and sub-band (SRS resource configuration template #2). The CSI reporting configuration could also be arranged as pool of templates based on the carrier / propagation properties. For example, one CSI reporting template for the FR1-TDD-pool configuration could contain settings for periodic reporting and Synchronization Signal (SS)-RSRP (CSI report template #3), another CSI report template for periodic reporting with codeBookType-2, sub-band-CQI-RI-PMI (CSI report template #2) and another CSI report template could contain settings for periodic reporting with codeBookType-1 , wide-band-CQI-RI-PMI (CSI report template #1).

[0281] Fig. 4 shows example signaling according to subject-matter described herein. Fig. 4 illustrates a procedure for the apparatus, e.g. the UE, to derive a CSI resource and / or CSI resource mapping form the CSI resource configuration templates and carrierspecific configuration, in particular UE-specific carrier configuration, which may contain the mapping to the templates.

[0282] Step 410: The apparatus, e.g. the UE, may receive, from a network device, at least one resource pool configuration which includes at least a plurality of CSI resource configuration templates. Optionally, the at least one resource pool configuration may include a plurality of CSI reporting configuration templates. The CSI resource configuration templates may include CSI-RS resource configuration templates and / or CSI-IM resource configuration templates. The resource pool configuration may be carrier-agnostic or at least bandwidth agnostic within a carrier.

[0283] Step 420: The apparatus, e.g. the UE, may receive, from the network device, at least one carrier-specific configuration (e.g., active carrier configuration) assigned to the apparatus. The at least one carrier-specific configuration assigned to the apparatus may be included in a RRC message (e.g., RRC Reconfiguration message) received from or transmitted by the network device. The at least one carrier-specific configuration may indicate at least one template of the at least one resource pool configuration to be applied to at least one active carrier. The at least one carrier-specific configuration may include at least one indication that links or maps (e.g. mapping) at least one of: at least one the plurality of CSI resource configuration templates or at least one of a plurality of CSI reporting configuration templates to at least one active carrier of the at least one carrierspecific configuration. The at least one carrier-specific configuration may include at least one template ID that specifies which template of at least one of: i) the plurality of CSI resource configuration templates, orii) a plurality of CSI reporting configuration templates, are to be used by the apparatus for at least one active carrier. The at least one carrierspecific configuration may include at least one time domain parameter for CSI reporting and / or optionally may include the time domain parameter of the CSI resource.

[0284] Step 430: Based at least in part on at least one carrier-specific configuration assigned to the apparatus and the plurality of CSI resource configuration templates, the apparatus, e.g. the UE, may determine at least one CSI resource to be measured. The atleast one CSI resource to be measured may be specific to at least one active carrier. The at least one CSI resource to be measured may be determined by applying at least one of the plurality of CSI resource configuration templates to at least one active carrier.
