[0080] DETAILED DESCRIPTION
[0081] FIG. 1 schematically illustrates an example of a network 100 suitable for use with examples of the present disclosure. The network (which may be referred to as NW) comprises a plurality of network entities (which may be referred to as NEs), including:
[0082] • terminal apparatuses 110 (which may be referred to as terminal nodes or User Equipment, UE),
[0083] • access apparatuses 120 (which may be referred to as access nodes, gNodeBs, gNBs, or Base Stations, BSs),
[0084] • one or more core network apparatuses 130 (which may be referred to as core nodes, core functions, core entities or core network entities).
[0085] The terminal nodes 110 and access nodes 120 communicate with each other. The one or more core network nodes 130 may, in some but not necessarily all examples, communicate with each other. The one or more access nodes 120 may, in some but not necessarily all examples, communicate with each other.
[0086] The network 100, in the example illustrated in FIG. 1 , comprises a radio telecommunications network in which at least some of the terminal nodes 110 and access nodes 120 communicate with each other using transmission / reception of radio waves. In this regard, the network 100 comprises a Radio Access Network, RAN, such as a cellular network comprising a plurality of cells 122 each served by an access node 120. The access nodes 120 comprise cellular radio transceivers. The terminal nodes 110 comprise cellular radio transceivers.
[0087] In the example illustrated and discussed below, the network 100 is a New Radio, NR, network of the Third Generation Partnership Project, 3GPP, and its fifth generation, 5G, New Radio, NR, technology. In other examples, the network 100 may be a network beyond 5G, for example a next generation (i.e. sixth generation, 6G) Radio Network that is currently under development (i.e. an evolution of the NR network and its 5G technology).
[0088] The interfaces between the terminal nodes 110 and the access nodes 120 are radio interfaces 124 (e.g., llu interfaces). The interfaces between the access nodes 120 and one or more core nodes 130 are backhaul interfaces 128 (e.g., S1 and / or Next Generation, NG, interfaces).
[0089] Depending on the exact deployment scenario, the access nodes 120 may be RAN nodes such as NG-RAN nodes. NG-RAN nodes may be gNodeBs, gNBs, that provide NG user plane and control plane protocol terminations towards the UE. The gNBs are connected by means of NG interfaces to a 5G Core (5GC), not least for example to an Access and Mobility Management Function, AMF, by means of an NG Control Plane, NG-C, interface and to a User Plane Function, UPF, by means of an NG User Plane, NG-U, interface.
[0090] The access nodes 120 may be interconnected with each other by means of Xn interfaces 126.
[0091] The cellular network 100 may be configured to operate in licensed frequency bands, or unlicensed frequency bands (not least such as: unlicensed bands that rely upon a transmitting device to sense the radio resources / medium before commencing transmission, such as via a Listen Before Talk, LBT, procedure; and a 60GHz unlicensed band where beamforming may be required to achieve required coverage).
[0092] The access nodes 120 may be deployed in an NG standalone operation / scenario. The access nodes 120 may be deployed in a NG non-standalone operation / scenario. The access nodes 120 may be deployed in a Carrier Aggregation, CA, operation / scenario. The access nodes 120 may be deployed in a Dual Connectivity, DC, operation / scenario, i.e., Multi Radio Access Technology - Dual Connectivity, MR-DC, or NR-DC. The access nodes 120 may be deployed in a Multi Connectivity, MC, operation / scenario. In such non-standalone / dual connectivity deployments, the access nodes 120 may be interconnected to each other by means of X2 or Xn interfaces, and connected to an Evolved Packet Core, EPC, by means of an S1 interface or to the 5GC by means of a NG interface.
[0093] A terminal node 110, in addition to being capable of communicating (i.e. with other terminal nodes) via access nodes 120 of the network 100, may also be capable of and configured to communicate directly with one or more other terminal nodes. In this regard, the terminal node may be capable of and configured to perform device-to-device, D2D, communication - which may be referred to as Sidelink, SL, communication. Such D2D / SL communication may use a PC5 interface. PC5 refers to a reference point where the terminal node communicates directly with another terminal node over a direct channel (i.e. communication via an access node is not required). D2D communications may be short- range, network-less, direct communications. SL in New Radio (NR) is defined in 3GPP’s release 16 of 5G NR.
[0094] In the example of FIG. 1 the core node 130 is shown as a single entity. In some examples the core node 130 could be distributed across a plurality of entities. For example, the core node 130 could be cloud based or distributed in any other suitable manner. The core node / core entities may provide one or more functions, not least such as: User Plane Function UPF, Session Management Function SMF, Policy Control Function PCF, and Application Function AF.
[0095] The access nodes 120 are network elements in the network responsible for radio transmission and reception in one or more cells 122 to or from the terminal nodes 110. The access nodes 120 are the network termination of a radio link. Each access node may be a Transmission / Reception Point, TRP, or may host one or more TRPs.
[0096] An access node 120 may be implemented as a single network equipment, or have a split architecture that is disaggregated / distributed over two or more access nodes, such as a Central Unit, CU, a Distributed Unit, DU, a Remote Radio Head-end, RRH, using different functional-split architectures and different interfaces.
[0097] The terminal nodes 110 are network elements in the network that terminate the user side of the radio link. They are devices allowing access to network services. Terminal node 110 functionalities may be performed also by Mobile Termination, MT, part of an Integrated Access and Backhaul, IAB, node. The terminal nodes 110 may be referred to as User Equipment, UE, mobile equipment, mobile terminals, or mobile stations.
[0098] The term ‘User Equipment’ may be used to designate mobile equipment comprising means, such as a smart card, for authentication / encryption etc. such as a Subscriber Identity Module, SIM. A SIM / SIM card can be a memory chip, a module, or a Universal Subscriber Identity Module (USIM). In some examples, the term ‘User Equipment’ can be used to designate a location / position tag, a hyper / smart, a hyper / smart sensor, or a mobile equipment comprising circuitry embedded as part of the user equipment for authentication / encryption such as a software SIM.
[0099] In the following description, a terminal node may be referred to simply as UE 110.
[0100] In the following description, an access apparatus / access node to a RAN (e.g. a cellular network not least such as a 5G or 6G next generation RAN) may be referred to interchangeably as BS 120 or gNB 120.
[0101] There now follows a brief discussion of a framework for reporting channel measurements, in particular CSI reporting.
[0102] 3GPP has defined Layer 1, L1 , reporting in Release 15 (and onwards ) as well as for Release 18 Low-Layer Triggered Mobility, LTM, as part of a CSI reporting framework (as defined in Technical Specification, TS, 38.214, V18.1.0, see not least 5.2).
[0103] TS, 38.214, V18.1.0, 5.2.1.1 defines reporting settings for configuring a UE’s reporting of CSI measurements. Each reporting setting (e.g. CSI-ReportConfig) is associated with / refers to resource settings. TS, 38.214, V18.1.0, 5.2.1.2 defines resource settings (e.g. CSI-ResourceConfig) for configuring CSI resources for the UE to use to perform CSI measurements.
[0104] Each CSI Resource Setting CSI-ResourceConfig contains a configuration of a list of S>1 CSI Resource Sets (given by higher layer parameter csi-RS-ResourceSetList), where the list is comprised of references to either or both of NZP CSI-RS resource set(s) and SS / PBCH block set(s) or the list is comprised of references to CSI-IM resource set(s). The information element, IE, CS!-ResourceConfig^\nQS a group of one or more: NZP- CSI-RS-ResourceSe t, CSI-IM-ResourceSe t a n d / o r CS / SSB-ResourceSe t.
[0105] The CSI reporting framework in L1 is separated from the unified TCI state framework. The CSI framework is used for reporting measurements on downlink reference signals. The TCI state framework is used for indicating quasi-colocation, QCL, references for downlink signals and channels, as well as uplink signals and channels. The IE TCI-State associates one or two DL reference signals with a corresponding QCL type.
[0106] As will be set out and described in further detail below, certain examples of the present disclosure seek to provide an enhanced framework for reporting channel measurements (e.g. an enhanced CSI reporting framework) wherein:
[0107] - a resource configuration (e.g. CSI resource configuration) for channel measurement (e.g. CSI measurement) is provided to a UE by a configuration of TCI state identifiers, IDs, by reference to an existing or other configured list of TCI states (whereupon the UE can determine resource(s) to be used for channel measurement based on a TCI state ID. The TCI state ID itself refers to a TCI state configuration which, in turn, provides a measurement Reference Signal, RS, that the UE uses for channel measurement)
[0108] - a reporting configuration, which is associated with the resource configuration, is provided to the UE for configuring the reporting of the measurement of the reference signal associated with the TCI State
[0109] - a reporting format may include a TCI state resource indicator and the reported measurement quantity may be based on the CSI resource configuration of TCI state IDs.
[0110] Advantageously, such a CSI reporting framework may leverage the TCI state framework, as well as existing configurations (e.g. of configured TCI states), for performing channel measurements and reporting (such as CSI measurements and reporting).
[0111] Also, advantageously, such a TCI-based CSI reporting framework may allow a dynamic CSI reporting switch from a single-TRP to multi-TRP, single panel to multi-panel. This can be done since a TCI state codeword (which may be used to activate certain TCI states for measurement and reporting) may have TCI state for single-TRP or multiple TCI states for multi-TRP. FIG. 2 schematically illustrates an example of a procedure 200 and a signalling framework, between a first apparatus (in this example UE 110) and a second apparatus (in this example a BS 120), for supporting the procedure.
[0112] The signalling diagram of FIG. 2 (and also of FIG. 5 below) can be considered to illustrate a plurality of methods, in the sense that each signalling diagram can be considered to illustrate one or more actions, processes or procedures performed by / at a plurality of actors / entities, e.g. UE 110 and BS 120 (and, in some implementations employing the use of sidelink communications and transmissions, a UE and a further UE). The signalling diagrams can therefore be considered to illustrate a plurality of individual methods performed by each respective individual actor / entity of the plurality of the actors / entities.
[0113] In block 201, the UE 110 receives, from the BS 120, first information 202 for configuring resource(s) 203 for channel measurement(s). The resources are indicated, in the first information, via one or more Transmission Configuration Indication, TCI, states 204.
[0114] In this regard, the UE may receive a CSI resource configuration comprising TCI state IDs configured in a list of TCI States (by RRC, or RRC + MAC CE).
[0115] The first information (which may be referred to herein “resource configuration (TCI for CSI)” or simply “TCI for CSI”), may comprise at least one of the following: a resource setting such as a CSI resource configuration; a set or list of TCI state identifiers, IDs; an indicator for indicating whether the first information comprises a set of TCI state IDs; or a plurality of sets of resources for channel measurements, and wherein each set of resources for channel measurements is assigned its own identifier (e.g. a CSI resource configuration ID).
[0116] The UE may be configured (e.g. via Radio Resource Control, RRC) with a set of TCI states, and the TCI state(s) 204 indicated in the first information may be a subset of the set of configured TCI states.
[0117] The UE may be configured with a set of resources for the set of TCI states (i.e. TCI state resources), and the channel measurement resource(s) 203 may be determined based at least in part on one of the configured set of resources for the set of TCI states. The TCI states indicated in the first information may comprise at least one of the following: one or more TCI state IDs for downlink TCI states, one or more TCI state IDs for uplink TCI states, or one or more TCI state IDs for joint downlink and uplink TCI states.
[0118] In block 205, the UE receives, from the BS, second information 206 for configuring reporting of channel measurement result(s). The second information (which in some examples may be a reporting setting such as a CSI reporting configuration) may comprise a reporting configuration 207.
[0119] In this regard, the UE may receive a CSI reporting configuration 207 (by RRC, or MAC CE) referencing a CSI resource configuration with TCI state IDs.
[0120] The second information may comprise at least one of the following: a reporting setting such as a CSI reporting configuration; at least one indication of at least one TCI state; a reference to the first information; at least one identifier (e.g. a CSI resource configuration ID) for identifying at least one of a plurality of sets of resources for channel measurements indicated in the first information; an indicator for indicating whether the second information comprises a reference to resources for channel measurements, wherein the resources for channel measurements are indicated via TCI states; a plurality of reporting configurations, and wherein reporting configuration is assigned an identifier (e.g. a CSI reporting configuration ID); an indication of a type of measurement to be performed (e.g. an indication of quantity to be measured: Reference Signal Received Power, RSRP; Signal to Interference and Noise Ratio, SINR; Channel Quality Indicator, CQI; Precoding Matrix Indicator, PMI etc); an indication of a number of TCI states to be reported; or an indication of a channel measurement resource for a TCI State ID (e.g.: a QCL reference RS 1 , a QCL reference RS 2, a configured measurement RS in the indicated TCI state, a QCL source RS of the RS 1 or RS 2). The second information may be received by the UE, at least in part, via RRC signalling and / or Medium Access Control, MAC, signalling.
[0121] The UE may receive, from the BS, an indication (which may be received via Medium Access Control, MAC signalling) to activate at least one of the one or more TCI states indicated in the first information. Responsive to which, the UE may (in block 208) perform channel measurement(s) using one of the resources, indicated via TCI states in the first information, that is associated with the activated TCI state. The indication may comprise at least one of the following: a Medium Access Control, MAC, Control Element, CE; an indication (e.g. a CSI resource configuration ID) of the one or more resources for one or more channel measurements of the first information; or an indication (e.g. a bit map of TCI State IDs) of at least one of the one or more TCI states indicated in the first information.
[0122] The UE may receive, from the BS, an indication (which may be received via Downlink Control Information, DCI) of a particular TCI state of the TCI states indicated in the first information. Responsive to which, the UE may (in block 208) perform channel measurement(s) using one of the resources, indicated via TCI states in the first information, that is associated with the indicated particular TCI state. The indication may comprise a codepoint, wherein the UE has been previously configured with a mapping of codepoints to various of the TCI states indicated in the first information.
[0123] In block 208, the UE performs channel measurement(s) using the resource(s) indicated, in the first information, via TCI state(s).
[0124] In this regard, the UE may, responsive to receipt of the second information in block 205, perform CSI measurements using CSI resources indicated, via TCI states, in the CSI resource configuration received in the first information in block 201. In this regard, the UE may perform CSI measurements on a configured resource that is included or associated with a TCI State that corresponds to one of the TCI state IDs listed in the CSI resource configuration.
[0125] The UE may determine one or more particular channel measurement resource(s) it is to use to perform channel measurement(s) thereon, wherein the determination is based at least in part on one or more of the following: the first information; the second information; or one or more activated TCI states.
[0126] The UE may determine one or more particular channel measurement resource(s) it is to use in performing channel measurement(s) based at least in part by determining / selecting, from a set of resources for a set of TCI states that the UE has been configured with, at least one resource that is associated with / corresponds to at least one TCI state indicated in either the first information or in the second information.
[0127] Each of the TCI states 204 indicated in the first information may be associated with a reference signal. The channel measurement(s) may be performed on at least one channel, wherein the at least one channel is determined based at least in part on the reference signal associated with a particular TCI state.
[0128] In block 209, the UE reports the result(s) of the channel measurement(s), wherein the reporting is based at least in part on the second information. In this regard, in some examples, the UE may report CSI measurements in accordance with a CSI reporting configuration received in block 205. In this regard, the UE may report measurement result(s) associated with at least one of the TCI state IDs listed in the CSI resource configuration.
[0129] The channel measurement result(s) may be reported via one or more of the following:
[0130] MAC signalling;
[0131] Uplink Control Information, UCI; a Physical Uplink Shared Channel, PUSCH; or a Physical Uplink Control Channel, PUCCH.
[0132] FIG. 3 schematically shows an example of a first option for CSI resource configurations / “TCI for CSI” 203.
[0133] In the example of the first option of FIG. 3, a UE is configured with a TCI state list 301 (e.g. via RRC and which comprises a set of N TCI state IDs of N TCI states) for CSI resource configuration. The CSI resources for a particular CSI resource configuration are indicated via references to a subset of the TCI states of the TCI State list 301 . A CSI resource configuration in which CSI resources are indicated via TCI states may be referred to herein as “TCI for CSI”. The TCI for CSI may be a dedicated list of TCI states of TCI states IDs listed in downlink (or joint) TCI states and / or uplink TCI states. Each list can be referred to with its own resource configuration identifier i.e. CSI resource config ID.
[0134] In the example of FIG. 3, a first CSI resource configuration 203_1 (having resource configuration identifier 302_1 , namely CSI resource config ID 1) has M entries that indicate a first set of CSI resources via reference to a first subset 204_1 of M of the N TCI states of the TCI State list 301. A KthCSI resource configuration 203_K (having resource configuration identifier 302_K, namely CSI resource config ID K) has L entries that indicate a Kthset of CSI resources via reference to a Kthsubset 204_K of L of the N TCI states of the TCI State list 301 .
[0135] FIG. 4 schematically shows an example of a second option for CSI resource configurations / “TCI for CSI” 203.
[0136] In the example of the second option of FIG. 4, the CSI resource configuration 203_1 comprises or consists of a set of TCI states 204_1 that are activated by MAC CE 401 for CSI measurement(s).
[0137] One or more, or all, of the TCI states of the set of TCI states 204_1 of a CSI resource configuration 203_1 can be selectively activated 402 by MAC CE 401 for CSI measurement for the particular CSI resource configuration. The TCI state IDs (of the set of TCI state IDs 204_1 of the CSI resource configuration 203_1) that are activated by the MAC CE are considered by the UE as active for measurements (and reporting).
[0138] In one example, the MAC CE format comprises a field referring to a particular CSI resource config ID (with resource list type TCI). This provides an indication of a selection of a particular CSI resource configuration.
[0139] In one example, the MAC CE format comprises a field indicating a bit map of TCI state IDs active for the measurements. This provides an indication of a selection of a subset of one or more TCI state IDs of a set of TCI state IDs a particular CSI resource configuration. In a third option (not shown in the figures) for CSI resource configurations / “TCI for CSI”, the CSI resource configuration / TCI for CSI comprises or consists of one or more TCI States that are indicated by DCI.
[0140] The one or more TCI state IDs of a CSI resource configuration that are indicated by DCI are considered by the UE as active for measurements (and reporting).
[0141] In some examples, DCI can indicate a set of TCI state IDs by codepoint which maps to a particular CSI resource configuration.
[0142] For example, a codepoint value e.g. 00 or 01 etc., can map to specific resource configuration ID. For instance:
[0143] 00 -> CSI resource config 1
[0144] 01 -> CSI resource config 2
[0145] 10 -> CSI resource config K
[0146] 11 -> null (no resource config)
[0147] In some examples, DCI can indicate a set of TCI state IDs by codepoint which maps to a particular CSI resource configuration, wherein TCI state IDs from the indication particular CSI resource configuration can then be activated for CSI reporting by a MAC CE.
[0148] The mapping of codepoint may be configured using RRC signaling. The mapping between codepoint and CSI resource configuration can be configured separately, i.e. the mapping part of a reporting configuration, or a CSI resource configuration.
[0149] In some examples, any combination of above options can be used.
[0150] In some examples, the CSI resource config (or similar parameter in 6G and beyond) may comprise an indication whether the resource set list lists TCI state IDs.
[0151] RRC configuration of TCI for CSI reporting
[0152] In some examples, the CSI reporting config uration(s) can be configured by RRC.
[0153] Each CSI reporting configuration may comprise at least one of the following fields: - a reference to the resource set list that lists TCI state IDs associated with the respective reporting configuration (e.g. reference to the CSI reporting configuration associated with the CSI reporting configuration)
[0154] - a reporting quantity (e.g. RSRP, SINR, CQI, PMI, etc.)
[0155] - a number of TCI states to be reported an indication of channel measurement resource (e.g. a particular measurement reference signal [this may be done since a TCI state information element may comprise other reference signals]) in the TCI State ID, e.g. at least one of: o a QCL reference RS 1 o a QCL reference RS 2 o a Configured (channel) measurement RS in the TCI state o a Configured (channel) n-port measurement RS in the TCI state (e.g. 2- port or 4-port) o a QCL source RS of the RS1 or RS2 o or alternatively a measurement resource indication may be included in the CSI resource configuration itself.
[0156] In some examples, a CSI reporting configuration associated with a TCI state ID may also include an indication of one or more interference measurement resources (e.g. specific measurement resources that are to be used for interference measurement, such as measuring an interference component for e.g. a SINR measurement). Such resources may share the same or a different physical cell IDs
[0157] MAC CE configuration of TCI for CSI
[0158] In some examples, the CSI reporting configuration may be configured by a MAC CE (NW to UE).
[0159] In some examples, the MAC CE may include a reporting configuration ID.
[0160] In some examples, the MAC CE may include a reporting configuration ID or a MAC CE identifier (Logical Channel Identifier, LCID) that indicates that the MAC CE configures the reporting of TCI states and that the TCI State IDs refer to a list of TCI State IDs configured by RRC for CSI reporting of:
[0161] - a list of TCI states that are activated for the reporting, and associated with the specific reporting configuration ID in the same MAC CE, an indication of measurement quantity e.g. RSRP.
[0162] In some examples, the configuration may be a combination of RRC and MAC in such a manner that one or more parameters may be provided by the RRC and rest by the MAC CE.
[0163] In some examples, the UE may be configured to report using a MAC CE wherein:
[0164] - the MAC CE report format includes a reporting configuration identifier
[0165] - the measurement resources are determined based on the RRC / MAC CE configuration
[0166] - the listed identifiers are the TCI State IDs associated with CSI reporting.
[0167] In some examples, the CSI reporting configuration may comprise a configuration wherein the reporting configuration is implicit based on the activated TCI states (for beam indication). The reporting configuration may determine the reported resources based on the activated TCI state IDs.
[0168] In some examples, the CSI reporting is performed using MAC CE.
[0169] In some examples, the CSI reporting is performed using UCI (e.g. on PLISCH or PLICCH)
[0170] In some examples, the resource indicator is derived based on the TCI state IDs listed in the CSI measurement configuration.
[0171] FIG. 5 schematically illustrates an example of a procedure 500 and a signalling framework, between a first apparatus (in this example UE 110) and a second apparatus (in this example a BS 120), for supporting the procedure.
[0172] Certain aspects, features and functionality of the procedure 500 are similar to certain aspects, features and functionality of the procedure 200 of FIG.2 as well as various of the other features and functionality described above. Hence, certain aspects, features and functionality of the procedure 200, as well as various of the other features and functionality described above, may be relevant mutatis mutandis to the procedure 500 and shall not be repeated / reiterated in detail. In block 501 , the UE 110 receives, from the BS 120, first information 502 for configuring resource(s) 503 for interference measurement(s). The resources are indicated, in the first information, via one or more Transmission Configuration Indication, TCI, states 504.
[0173] In this regard, the UE may receive an interference resource configuration comprising TCI state IDs configured in a list of TCI States (by RRC, or RRC + MAC CE).
[0174] In block 505, the UE receives, from the BS, second information 506 for configuring reporting of interference measurement result(s). The second information may comprise of a reporting setting such as an interference reporting configuration 507. The interference reporting configuration configures the reporting of at least one interference measurement result such that at least one measurement result is reported in a reporting occasion (e.g. reporting occasion 603 as illustrated and discussed further below in FIG. 6).
[0175] The UE may receive, from the BS, a request to perform an interference measurement (not shown in FIG. 7). The UE may perform the interference measurement responsive, at least in part, to the received request.
[0176] In block 508, the UE performs one or more interference measurements using the resource(s) indicated, in the first information, via TCI state(s). The one or more interference measurements are performed in respective one or more interference measurement occasions (e.g. interference measurement occasions 601 as illustrated and discussed further below in FIG. 6) to measure / evaluate one or more interference measurement results. Details of block 508’s performance of interference measurements are illustrated and discussed further below with respect to FIG. 7.
[0177] In block 509, the UE reports the interference measurement result that is measured / evaluated / selected in block 508. The reporting is conditional at least in part on the second information.
[0178] FIG. 6 schematically illustrates a time / frequency diagram showing a set / plurality of interference measurement occasions 601_1 - 602_n (in which interference measurements are performed to measure / evaluate interference measurement results) and a reporting occasion 603 (in which an interference measurement result is reported). FIG. 6 also shows a DCI 601. As indicated in the figure, each of the set / plurality of interference measurement occasions 602 are prior to the reporting occasion 603.
[0179] FIG. 7 schematically illustrates further detail of block 508’s performance of interference measurements, and in particular the selection / evaluation of an interference measurement result that is to be reported (in block 509) in a reporting occasion.
[0180] As will be set out below, in effect, the interference measurement result that is reported in block 509 may be determined via one of 3 options.
[0181] In block 701 , a determination is made where is a set 602 of a plurality of interference measurement occasions that occurs prior a reporting occasion 603.
[0182] Responsive to determining that there is such a set 602 interference measurement occasions that occurs prior a reporting occasion 603, one of the following 3 options may be performed.
[0183] Option a)
[0184] In block 702_a_1, the UE selects one of the interference measurement occasions from the set of interference measurement occasions.
[0185] The selection of the interference measurement occasion may be based at least in part on a time of the at least one reporting occasion. For instance, the interference measurement occasion selected may be one that is the closest in time to the reporting occasion. For instance, with regards to FIG. 6, the interference measurement occasion 602_n, which is closest in the time domain to the reporting occasion 603, may be selected.
[0186] In block 702_a_2, the UE measures an interference measurement result during the selected interference measurement occasion.
[0187] The interference measurement result measured during the selected interference measurement occasion is then reported (in block 509 of FIG. 5) in the reporting occasion 603. In block 702_b_1 , the UE performs an interference measurement in each of the plural interference measurement occasions so as to measure a plurality of interference measurement results (for each respective interference measurement occasion of the plurality of interference measurement occasions).
[0188] In block 702_b_2, the UE selects, for reporting, an interference measurement result from the plurality of interference measurement results.
[0189] The selection of the interference measurement result may be based at least in part on a value of the interference measurement result. For instance, the interference measurement result selected may be one that has the highest value from amongst the plurality of measurement results.
[0190] The selected interference measurement result is then reported (in block 509 of FIG. 5) in the reporting occasion 603.
[0191] In block 702_c_1 (similar to block 702_b_1), the UE performs an interference measurement in each of the plural interference measurement occasions so as to measure a plurality of interference measurement results (for each respective interference measurement occasion of the plurality of interference measurement occasions).
[0192] In block 702_c_2, the UE evaluates, for reporting, an interference measurement result based on the plurality of interference measurement results.
[0193] The evaluation of the interference measurement result may comprise evaluating an average of the plurality of interference measurement results and using the average as the interference measurement result to be reported.
[0194] The evaluated interference measurement result is then reported (in block 509 of FIG. 5) in the reporting occasion 603.
[0195] One example implementation may be as follows. A UE determines that it has been configured with interference measurement and reporting, and the TCI state IDs for CSI reporting includes an IM (interference measurement) resource.
[0196] The UE is configured to report a quantity including interference component (e.g. CQI / SINR).
[0197] The UE determines, upon request from its serving cell, to measure interference on the resource provided in the TCI state of an indicated TCI state ID.
[0198] If the UE determines that there are plurality of interference measurement occasions (e.g. within a window / pre-determined time period) prior to the reporting occasions, the UE either: a) selects one interference measurement occasion (e.g. which is closest, in time, to the reporting occasions) and measures interference on the selected interference measurement occasion, b) measures interference on all interference measurement occasions (or a subset of interference measurement occasions) and selects the highest measured interference of the interference measurement occasions that it measured c) measures interference on all interference measurement occasions (or a subset of interference measurement occasions) and averages the interference over the all (or subset of) interference measurement occasions.
[0199] The UE computes CQI based on the interference measurement (and the RSRP measurement).
[0200] The above described component blocks (e.g. of the signalling diagrams) are functional and the functions, along with the further functions / functionalities described above, can be performed by a single physical entity (such as an apparatus as is described with reference to FIG. 8 - embodied in a UE or BS). The functions described can also be implemented instructions, e.g. by a computer program (such as is described with reference to FIG. 9 - for execution by a processor of a UE or a BS).
[0201] FIG. 8 schematically illustrates a block diagram of an apparatus 10 for performing the methods, processes, procedures and signaling described in the present disclosure and illustrated in FIGs. 2 to 7. In this regard the apparatus can perform the roles of an entity (such as: UE or BS) in the illustrated and described methods.
[0202] The component blocks of FIG. 8 are functional and the functions described can be performed by a single physical entity, not least such as a UE or BS.
[0203] The apparatus comprises a controller 11, which could be provided within a device / entity, not least such as a UE or BS.
[0204] The controller 11 can be embodied by a computing device, not least such as those mentioned above. In some, but not necessarily all examples, the apparatus can be embodied as a chip, chip set, circuitry or module, i.e. for use in any of the foregoing.

[0206] The controller 11 can be implemented using instructions that enable hardware functionality, for example, by using executable instructions of a computer program 14 in a general-purpose or special-purpose processor 12 that can be stored on a computer readable storage medium 13, for example memory, or disk etc, to be executed by such a processor 12.
[0207] The processor 12 is configured to read from and write to the memory 13. The processor 12 can also comprise an output interface via which data and / or commands are output by the processor 12 and an input interface via which data and / or commands are input to the processor 12. The apparatus can be coupled to or comprise one or more other components 15 (not least for example: a radio transceiver, sensors, input / output user interface elements and / or other modules / devices / components for inputting and outputting data / commands).
[0208] The memory 13 stores instructions such as a computer program 14 comprising such instructions (e.g. computer program instructions / code) that controls the operation of the apparatus 10 when loaded into the processor 12. The instructions of the computer program 14, provide the logic and routines that enables the apparatus to perform the methods, processes and procedures described in the present disclosure and illustrated in FIGs. 2 to 7. The processor 12 by reading the memory 13 is able to load and execute the computer program 14.
[0209] The instructions may be comprised in a computer program, a non-transitory computer readable medium, a computer program product, a machine readable medium. 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). In some but not necessarily all examples, the computer program instructions may be distributed over more than one computer program.
[0210] Although the memory 13 is illustrated as a single component / circuitry it can be implemented as one or more separate components / circuitry some or all of which can be integrated / removable and / or can provide permanent / semi-permanent / dynamic / cached storage.
[0211] Although the processor 12 is illustrated as a single component / circuitry it can be implemented as one or more separate components / circuitry some or all of which can be integrated / removable. The processor 12 can be a single core or multi-core processor.
[0212] The apparatus can include one or more components for effecting the methods, processes and procedures described in the present disclosure and illustrated in FIGs. 2 to 7. It is contemplated that the functions of these components can be combined in one or more components or performed by other components of equivalent functionality. The description of a function should additionally be considered to also disclose any means suitable for performing that function.
[0213] Where a structural feature has been described, it can be replaced by means for performing one or more of the functions of the structural feature whether that function or those functions are explicitly or implicitly described.
[0214] Although examples of the apparatus have been described above in terms of comprising various components, it should be understood that the components can be embodied as or otherwise controlled by a corresponding controller or circuitry such as one or more processing elements or processors of the apparatus. In this regard, each of the components described above can be one or more of any device, means or circuitry embodied in hardware, software or a combination of hardware and software that is configured to perform the corresponding functions of the respective components as described above.
[0215] The apparatus can, for example, be: a user equipment, base station or network node of a mobile cellular telecommunication system. The apparatus can be embodied by a computing device, not least such as those mentioned above. However, in some examples, the apparatus can be embodied as a chip, chip set, circuitry or module, i.e. for use in any of the foregoing.
[0216] In one example, the apparatus is embodied on a client device, a UE, a mobile cellular telephone, a hand held portable electronic device, a mobile communication device, a wearable computing device or a personal digital assistant, that can additionally provide one or more audio / text / video communication functions (for example tele-communication, video-communication, and / or text transmission (Short Message Service (SMS) / Multimedia Message Service (MMS) / emailing) functions), interactive / non-interactive viewing functions (for example web-browsing, navigation, TV / program viewing functions), music recording / playing functions (for example Moving Picture Experts Group-1 Audio Layer 3 (MP3) or other format and / or (frequency modulation / amplitude modulation) radio broadcast recording / playing), downloading / sending of data functions, image capture function (for example using a (for example in-built) digital camera), and gaming functions, or any combination thereof.
[0217] In some examples (such as wherein the apparatus is provided within a UE 110), the apparatus 10 comprises: at least one processor 12; and at least one memory 13 storing instructions that, when executed by the at least one processor 12, cause the apparatus at least to: receive, from a second apparatus, first information for configuring at least one resource for at least one interference measurement, wherein the at least one resource is indicated, in the first information, via at least one Transmission Configuration Indication, TCI, state; receive, from the second apparatus, second information for configuring reporting of at least one result of at least one interference measurement, wherein the at least one result is reported in respective at least one reporting occasion; perform the at least one interference measurement using the at least one resource indicated, in the first information, via at least one TCI state, wherein the at least one interference measurement is performed in respective at least one interference measurement occasion, and wherein the performing of the at least one interference measurement comprises: determining a plurality of interference measurement occasions that occurs prior to the at least one reporting occasion, and performing one of the following: measuring an interference measurement result during an interference measurement occasion of the plurality of interference measurement occasions, measuring a plurality of interference measurement results respectively during the plurality of interference measurement occasions and selecting an interference measurement result from the plurality of interference measurement results for reporting, or measuring a plurality of interference measurement results respectively during the plurality of interference measurement occasions and evaluating an interference measurement result based at least in part on the plurality of interference measurement results for reporting; and report the interference measurement result, wherein the reporting is based at least in part on the second information.

[0219] The apparatus can be provided in an electronic device, for example, a mobile terminal, according to an example of the present disclosure. It should be understood, however, that a mobile terminal is merely illustrative of an electronic device that would benefit from examples of implementations of the present disclosure and, therefore, should not be taken to limit the scope of the present disclosure to the same. While in certain implementation examples, the apparatus can be provided in a mobile terminal, other types of electronic devices, such as, but not limited to: mobile communication devices, hand portable electronic devices, wearable computing devices, portable digital assistants (PDAs), pagers, mobile computers, desktop computers, televisions, gaming devices, laptop computers, cameras, video recorders, GPS devices and other types of electronic systems, can readily employ examples of the present disclosure. Furthermore, devices can readily employ examples of the present disclosure regardless of their intent to provide mobility.

[0238] Although functions have been described with reference to certain features, those functions can be performable by other features whether described or not.
[0239] Although features have been described with reference to certain examples, those features can also be present in other examples whether described or not. Accordingly, features described in relation to one example / aspect of the disclosure can include any or all of the features described in relation to another example / aspect of the disclosure, and vice versa, to the extent that they are not mutually inconsistent.
[0240] The term ‘comprise’ is used in this document with an inclusive not an exclusive meaning. That is any reference to X comprising Y indicates that X can comprise only one Y or can comprise more than one Y. If it is intended to use ‘comprise’ with an exclusive meaning then it will be made clear in the context by referring to “comprising only one ...” or by using “consisting”.
[0241] In this description, the wording ‘connect’ and ‘communication’ and their derivatives mean operationally connected / in communication. It should be appreciated that any number or combination of intervening components can exist (including no intervening components), i.e. so as to provide direct or indirect connection / coupling / communication. Any such intervening components can include hardware and / or software components.
[0242] As used herein, the term "determine / determining" (and grammatical variants thereof) can include, not least: evaluating, calculating, computing, processing, deriving, measuring, investigating, identifying, looking up (for example, looking up in a table, a database or another data structure), ascertaining and the like. Also, "determining" can include receiving (for example, receiving information), retrieving / accessing (for example, retrieving / accessing data in a memory), obtaining and the like. Also, " determine / determining" can include resolving, selecting, choosing, establishing, inferring and the like.
[0243] As used herein, a description of an action should also be considered to disclose enabling, and / or causing, and / or controlling that action. For example, a description of transmitting information should also be considered to disclose enabling, and / or causing, and / or controlling transmitting information. Similarly, for example, a description of an apparatus transmitting information should also be considered to disclose at least one means or controller of the apparatus enabling, and / or causing, and / or controlling the apparatus to transmit the information.”
[0244] The term “means” as used in the description and in the claims may refer to one or more individual elements configured to perform the corresponding recited functionality or functionalities, or it may refer to several elements that perform such functionality or functionalities. Furthermore, several functionalities recited in the claims may be performed by the same individual means or the same combination of means. For example performing such functionality or functionalities may be caused in an apparatus by a processor that executes instructions stored in a memory of the apparatus.
[0245] References to a parameter, or value of a parameter, should be understood to refer to “data indicative of’, “data defining” or “data representative of’ the relevant parameter / parameter value if not explicitly stated (unless the context demands otherwise). The data may be in any way indicative of the relevant parameter / parameter value, and may be directly or indirectly indicative thereof.
[0246] In this description, reference has been made to various examples. The description of features or functions in relation to an example indicates that those features or functions are present in that example. The use of the term ’example’ or ‘for example’, ‘can’ or ‘may’ in the text denotes, whether explicitly stated or not, that such features or functions are present in at least the described example, whether described as an example or not, and that they can be, but are not necessarily, present in some or all other examples. Thus ‘example’, ‘for example’, ‘can’ or ‘may’ refers to a particular instance in a class of examples. A property of the instance can be a property of only that instance or a property of the class or a property of a sub-class of the class that includes some but not all of the instances in the class.
[0247] In this description, references to “a / an / the” [feature, element, component, means ...] are used with an inclusive not an exclusive meaning and are to be interpreted as “at least one” [feature, element, component, means ...] unless explicitly stated otherwise. That is any reference to X comprising a / the Y indicates that X can comprise only one Y or can comprise more than one Y unless the context clearly indicates the contrary. If it is intended to use ‘a’ or ‘the’ with an exclusive meaning then it will be made clear in the context. In some circumstances the use of ‘at least one’ or ‘one or more’ can be used to emphasise an inclusive meaning but the absence of these terms should not be taken to infer any exclusive meaning. 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.
[0248] The presence of a feature (or combination of features) in a claim is a reference to that feature (or combination of features) itself and also to features that achieve substantially the same technical effect (equivalent features). The equivalent features include, for example, features that are variants and achieve substantially the same result in substantially the same way. The equivalent features include, for example, features that perform substantially the same function, in substantially the same way to achieve substantially the same result. In this description, reference has been made to various examples using adjectives or adjectival phrases to describe characteristics of the examples. Such a description of a characteristic in relation to an example indicates that the characteristic is present in some examples exactly as described and is present in other examples substantially as described.
[0249] In the above description, the apparatus described can alternatively or in addition comprise an apparatus which in some other examples comprises a distributed system of apparatus, for example, a client / server apparatus system. In examples where an apparatus provided forms (or a method is implemented as) a distributed system, each apparatus forming a component and / or part of the system provides (or implements) one or more features which collectively implement an example of the present disclosure. In some examples, an apparatus is re-configured by an entity other than its initial manufacturer to implement an example of the present disclosure by being provided with additional software, for example by a user downloading such software, which when executed causes the apparatus to implement an example of the present disclosure (such implementation being either entirely by the apparatus or as part of a system of apparatus as mentioned hereinabove).
[0250] The above description describes some examples of the present disclosure however those of ordinary skill in the art will be aware of possible alternative structures and method features which offer equivalent functionality to the specific examples of such structures and features described herein above and which for the sake of brevity and clarity have been omitted from the above description. Nonetheless, the above description should be read as implicitly including reference to such alternative structures and method features which provide equivalent functionality unless such alternative structures or method features are explicitly excluded in the above description of the examples of the present disclosure.
[0251] Whilst endeavouring in the foregoing specification to draw attention to those features of examples of the present disclosure believed to be of particular importance it should be understood that the applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and / or shown in the drawings whether or not particular emphasis has been placed thereon.
