The network (which may be referred to as NW) comprises a plurality of network entities (which may be referred to as NEs), including: • terminal apparatuses 110 (which may be referred to as terminal nodes or User Equipment, UE), • access apparatuses 120 (which may be referred to as access nodes, gNodeBs, gNBs, or Base Stations, BSs), • one or more core network apparatuses 130 (which may be referred to as core nodes, core functions, core entities or core network entities). 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. The network 100, in the example illustrates 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. 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, and beyond) Radio Network that is currently under development (i.e. an evolution of the NR network and its 5G technology). 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). 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. The access nodes 120 may be interconnected with each other by means of Xn interfaces 126. 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). 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. 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. 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. 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. 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. 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. 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. In the following description, a terminal node may be referred to simply as UE 110. 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. There now follows a brief discussion of random access procedures, in particular a Random Access Channel, RACH, procedure, by which a UE 110 (initially or in a connected mode) accesses a cell 122 of a BS 120. In some examples, this may be referred as an initial access procedure. In a cell, there can be one or multiple Synchronization Signal Blocks, SSBs, to support beamforming. An SSB burst is transmitted by (a TRP of) a cell with certain periodicity in the cell (a default periodicity may be 20 ms). The following table summarizes SSB related parameters in Frequency Range 1, FR1, and FR2, along with example parameters for a new 6G frequency range, FR3, between 7-20 GHz: FR1 FR3 FR2-1 FR2-2 SSB SCS [kHz] 15 30 30 60 120 240 120 480 960 Frequency range [GHz] 0-3 3-6 0-3 3-6 6.4-8.5, 10-15 6.4-8.5, 10-15 24- 52.6 24- 52.6 52.6- 71 52.6- 71 52.6- 71 Maximum no. of SSBs 4 8 4 8 8 / 16 16 / (32) 64 64 64 64 64 Length of SS burst [ms] 2 3 1 2 2 / 4 2 / 4 4 2 4 1 0.5 The above frequency ranges and the naming convention should be seen as examples only. In a random access, RA, procedure (such as an initial access procedure), the UE selects a downlink, DL, Reference Signal, RS (e.g. SSB) for first access. Currently, in NR, two types of RA, procedure are supported: a 4-step RA type with MSG1, and a 2-step RA type with MSGA. Both types of RA procedure support Contention Based Random Access, CBRA, and Contention Free Random Access, CFRA. 3GPP TS 38.300, V18.1.0, section 9.2.6 discusses the Random Access Procedure. The UE selects a type of RA (e.g. 4-step or 2-step) at initiation of the RA procedure based on network configuration: when CFRA resources are not configured, a Reference Signal Received Power, RSRP, threshold is used by the UE to select between 2-step RA type and 4-step RA type; when CFRA resources for 4-step RA type are configured, the UE performs random access with 4-step RA type; when CFRA resources for 2-step RA type are configured, the UE performs random access with 2-step RA type. The network does not configure CFRA resources for 4-step and 2-step RA types at the same time for a Bandwidth Part, BWP. CFRA with 2-step RA type is only supported for handover. The MSG1 of the 4-step RA type consists of a preamble on Physical Random Access Channel, PRACH. After MSG1 transmission, the UE monitors for a response from the network within a configured window. For CFRA, a dedicated preamble for MSG1 transmission is assigned by the network and, upon receiving a random access response from the network, the UE ends the random access procedure. For CBRA, upon reception of the random access response, the UE sends MSG3 using an uplink, UL, grant scheduled in the response and monitors for a contention resolution. If the contention resolution is not successful after MSG3 (re)transmission(s), the UE goes back to MSG1 transmission. The MSGA of the 2-step RA type includes a preamble on PRACH and a payload on Physical Uplink Shared Channel, PUSCH. After MSGA transmission, the UE monitors for a response from the network within a configured window. For CFRA, a dedicated preamble and PUSCH resource are configured for MSGA transmission and, upon receiving the network response, the UE ends the random access procedure. For CBRA, if contention resolution is successful upon receiving the network response, the UE ends the random access procedure; while if fallback indication is received in MSGB, the UE performs MSG3 transmission using the UL grant scheduled in the fallback indication and monitors contention resolution. If contention resolution is not successful after MSG3 (re)transmission(s), the UE goes back to MSGA transmission. If the random access procedure with 2-step RA type is not completed after a number of MSGA transmissions, the UE can be configured to switch to CBRA with 4-step RA type. There now follows a brief discussion of Multiple Transmit / Receive Point (multi-TRP, or m-TRP), operation (which is defined in 3GPP Technical Specification 38.300 V18.0.0 6.12). In m-TRP operation, a serving cell can schedule a UE from two TRPs. This can provide better coverage, reliability and / or data rates for PDSCH, PDCCH, PUSCH, and PUCCH. There are two different operation modes to schedule m-TRP PDSCH transmissions: single-DCI and multi-DCI. For both modes, control of uplink and downlink operation can be done by physical layer and MAC layer, within a configuration provided by the RRC layer. In single-DCI mode, the UE is scheduled by the same DCI for both TRPs. In multi-DCI mode, the UE is scheduled by independent DCIs from each TRP. For inter-cell multi-TRP operation, for multi-DCI PDSCH transmission, one or more TCI states can be associated with SSB with a Physical Cell Identity, PCI, different from the serving cell PCI. Activated TCI states can be associated with at most one PCI different from the serving cell PCI at a time. Currently, under conventional RA procedures, a UE has access to a single cell upon successfully completing an RA procedure. Currently, in conventional RA procedures, it is not possible to indicate an availability / suitability for multiple TRP operation across different cells (each with a different Physical Cell Identity, PCI). Nor is it currently defined in 5G NR specifications how to indicate an availability / suitability for multiple TRP operation across different cells. Providing such an indication may be useful in enabling simultaneous uplink and / or downlink transmission, with respect to reference signals of more than one cell, to the network during / after RACH / initial access procedure. As will be discussed in further detail below, in various examples of the present disclosure, there is provided a procedure wherein a UE provides the network with additional information, namely an indication to the network that it is able perform inter-cell m-TRP operation. Inter-cell operation the UE may refer to communication (reception of uplink / downlink channels) associated with cells (e.g. a serving cell and at least one another cell other than serving cell) having different PCI. Inter-cell operation may also refer to operation where the UE may be scheduled (receive DCI) from a serving cell and a cell that has a different PCI than a serving cell. Inter-cell operation may further refer to: simultaneous reception and / or transmission or simultaneous transmission multi-panel, STxMP, of DL or UL signals and channels for m-TRP operation. In some examples the indication to be able to perform inter-cell mTRP operation may be signalled as part of a random access procedure. The UE may perform random access as the initial access (e.g. in an (RRC) IDLE / INACTIVE mode) or perform random access during an (RRC) CONNECTED mode. 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. In block 201, the UE 110 receives, from the BS 120, first information 202 that indicates whether one or more resources 203 support inter-cell m-TRP operation, wherein the one or more resources comprise: one or more cells (i.e. of one or more base stations, one of which may be the BS 120), one or more TRPs (i.e. of one or more cells), and / or one or more reference signals, RSs (i.e. of one or more TRPs of one or more cells). In this regard, the first information provides support information (which may be referred to as inter-cell m-TRP related information for (initial) random access) that the UE can use to determine, prior to the UE performing a random access procedure, which resources support inter-cell m-TRP operation and hence which resources the UE could select and seek to use for inter-cell m-TRP operation. For instance, the first information may comprise: a list of neighbouring cell IDs and RS IDs of neighbouring cells that can be used, in conjunction with the first cell and an RS of the first cell, for inter-cell m-TRP operation across the first and second cells. The first information may be transmitted by the BS via: system information, or a radio resource control, RRC, message. The first information may comprise an indication of at least one of the following: whether one or more cells 122 support inter-cell m-TRP operation; whether a first cell 122_1 (which the UE seeks to access in a random access procedure 209 as discussed further below) supports inter-cell m-TRP operation; whether one or more second cells 122_2 support inter-cell m-TRP operation with the first cell 122_1; whether one or more TRPs of the first cell can be used with one or more second TRPs of one or more second cells for inter-cell m-TRP operation; or whether one or more RSs (e.g. SSB or Channel State Information, CSI, RS) of the first cell can be used with one or more RSs (e.g. SSB or CSI-RS) of one or more second cells for inter-cell m-TRP operation. The first information may comprise an indication of at least one of the following: one or more cell identifiers (e.g. PCI); one or more TRP identifiers; and one or more RS identifiers. The first information may comprise an indication of at least one of the following: at least one set of cells, wherein each cell is associated with a set of RSs that are configured to serve as a Quasi Co-Location, QCL, reference; at least one set of TRPs of the first cell, wherein each TRP is associated with a set of RSs that are configured to serve as a QCL reference; one or more sets of TRPs of one or more second cells, wherein each TRP is associated with a set of RSs that are configured to serve as a QCL reference; a set of TRPs comprising TRPs from differing cells, wherein each TRP of each cell is associated with a set of RSs that are configured to serve as a QCL reference. Each QCL reference may be a QCL reference for use by the UE to perform reception, Rx, and / or transmission, Tx, of signals / channels based on a reference signal providing a QCL reference. The transmission / reception may be e.g. simultaneous Rx and / or Tx across multiple TRPs (of different cells). As an example of a QCL reference used for transmission or reception of channels / signals, the UE may determine the reception of a PDCCH / PDSCH using a downlink reference signal as QCL reference. In a further example, the UE may determine the parameters and / or spatial reception assumptions for the downlink channel based on the downlink reference signal (e.g. SSBICSI-RSITRS, Tracking Reference Signal) when the downlink channel and downlink reference signal are QCL’d. The QCL assumption may be configured / indicated by the network (e.g. via RRC signaling). Similarly the UE may use DL RS as QCL reference or spatial reference for transmission of uplink signals / channels. The first information may also comprise an indication that the UE is permitted to transmit second information 208 (as discussed further below in block 207) to the BS during a random access procedure. Such an indication may be explicit or implicit (i.e. the indication is implicitly provided to the UE by virtue of the mere BS’s transmission of the first information itself). In block 204, the UE determines at least one resource 205, of the one or more resources 205 indicated in the first information, that the UE is capable of using in an inter-cell m-TRP operational mode 206. For instance, where the first information comprises list of IDs of neighbouring cells 122_2 and / or IDs of RSs 205_2 of neighbouring cells that can be used for inter-cell m-TRP operation (i.e. with a first cell 122_1 and RSs 205_1 of the first cell), the UE may select a particular neighbouring cell ID and / or a particular RS ID of a neighbouring cell that is suitable for / a candidate for use in an inter-cell m-TRP operational mode 206. The UE’s determining of the one or more resources 205 may comprise at least one of: determining at least one second cell that supports inter-cell m-TRP operation with the first cell; determining at least one TRP of at least one second cell that supports intercell m-TRP operation with the first cell; and determining at least one RS of at least one second cell that can be used by the UE to perform inter-cell m-TRP operation with the first cell. The UE’s determining of the one or more resources 205 may be based at least part on measuring one or more RSs of the one or more resources indicated in the first information (for example so as to thereby select one or more RSs with the best RSRP). The UE’s determining of the one or more resources 205 may comprise selecting at least one identifier from one or more identifiers indicated in the first information 202. In block 207, the UE transmits second information 208 to the BS during a random access procedure 209 to a first cell 122_1 that is hosted by the BS. The second information provides an indication the resource(s) 205 determined in block 204. The second information may comprise an indication of at least one identifier selected by the UE from one or more identifiers indicated in the first information 202. In some examples, during the random access procedure but prior to the UE’s transmission of the second information in block 207, the UE may transmit, to the BS, an indication that the UE will transmit the second information to the BS during the random access procedure. In this regard, the UE may have been previously configured with a set of random access resources, such as RA resources (e.g. RACH preambles), wherein: a first subset of RA resources has been associated with indicating that the apparatus will transmit second information to the second apparatus during the random access procedure, and a second subset of RA resources has been associated with indicating that the apparatus will not transmit second information to the second apparatus during the random access procedure. The UE can thereby indicate that it will transmit the second information to the BS during the random access procedure by selecting and using a RA resource form the first subset of RA resources. In block 210, the UE receives third information 211 from the BS that is indicative of whether the UE is to operate in the inter-cell m-TRP operational mode 206. The third information is based at least in part on the second information. In this regard, upon receipt of the second information, the BS may determine whether or not to permit the UE to operate in the inter-cell m-TRP operational mode 206. The BS may then send third information indicative of the whether or not it permits the UE to operate in the inter-cell m-TRP operational mode. The third information may be received from the BS either: during the random access procedure (as indicated by 209’), or after completion of the random access procedure (as indicated by 209). The UE may determine one or more modes of inter-cell m-TRP operation that is it capable of performing and the third information may comprise an indication of the determined one or more modes of inter-cell m-TRP operation. The UE’s determinisation of inter-cell m-TRP operational modes it is capable of performing may be based, not least for example on one or more of: the resources indicated in the first information, measurements of signal strength / quality of RSs associated with such resources, as well as hardware capabilities of the UE (not least such as STxMP capabilities). The one or more modes of inter-cell m-TRP operation may comprise at least one of the following: Rx, using at least one downlink, DL, channel of the first cell and at least one DL channel of at least one other cell; Rx using at least one physical downlink control channel, PDCCH, of the first cell and at least one PDCCH of at least one other cell; Rx using at least one physical downlink shared channel, PDSCH, of the first cell and at least one PDSCH of at least one other cell; Tx using at least one uplink, UL, channel of the first cell and at least one UL channel of at least one other cell; Tx using at least one physical uplink control channel, PUCCH, of the first cell and at least one PUCCH of at least one other cell; or Tx using at least one physical uplink shared channel, PUSCH, of the first cell and at least one PUSCH of at least one other cell. The one or more modes of inter-cell m-TRP operation may comprise at least one of the following: Rx via the first cell and simultaneous Rx via at least one other cell; Rx via the first cell and simultaneous Tx via at least one other cell; Tx via the first cell and simultaneous Tx via at least one other cell; or Tx via the first cell and simultaneous Rx via at least one other cell. In block 212, the UE operates in the inter-cell m-TRP operational mode 206, wherein the UE’s operation in the inter-cell m-TRP operational mode is based at least in part on the third information, e.g. upon receiving confirmation that the UE is permitted to operate in the inter-cell m-TRP operational mode. In this regard, the UE may operate in an inter-cell m-TRP operational mode between / across: a first cell 122_1 that the UE’s random access procedure 209 sought to access, and a second cell 122_2. For example, the inter-cell m-TRP operational mode may comprise Rx and / or Tx over: at least one channel of the first cell, and at least one channel of another cell; wherein such operation is based at least in part on the first information. The UE’s operation in the inter-cell m-TRP operational mode may comprise: Rx and / or Tx over at least one channel of the first cell using an RS of the first cell as a QCL source, and Rx and / or Tx over at least one channel of another cell using an RS of the another cell as a QCL source. The Rx and / or Tx over at least one channel of the first cell can be simultaneous with the Rx and / or Tx over at least one channel of another cell. Alternatively, the Rx and / or Tx over at least one channel of the first cell can be non-simultaneous with the Rx and / or Tx over at least one channel of another cell. FIG. 3 shows a procedure 300 performed by a UE. In block 301, the network provisions (e.g. via a BS hosting a first cell in which the UE is camped), and the UE receives, system information. The system information comprises an indication that the first cell supports inter-cell m-TRP operation. The support signaling received by the UE may comprise: o an indication whether the first cell (provisioning the system information) supports inter-cell m-TRP. o an indication whether inter-cell m-TRP operation can be assumed for at least one cell in conjunction with the first cell provisioning the system information. o a set or sub-set of TRPs of the first cell that can be paired with another cell for m-TRP operation. Each TRP of the first cell may be associated with a set of DL RSs that may be indicated to be used as QCL references for simultaneous Tx / Rx. o a sub-set of TRPs from another cell that can be paired with a first cell for m-TRP operation. Each TRP of the another cell may be associated with a set of DL RSs that may be indicated to be used as QCL references for simultaneous Tx / Rx. o a set of cell pairs for which the UE can assume m-TRP operation. Each cell may be associated with set of DL RS indicated to be used as QCL references for simultaneous Tx / Rx. o a set of TRP pairs, from two different cells, that can support UL, DL or UL / DL m-TRP operation together. Each TRP of each cell may be associated with a set of DL RSs indicated to be used as QCL references for simultaneous Tx / Rx. In bock 302, the UE determines, based on the inter-cell m-TRP related information from the support signaling of block 301, at least one RS ID of at least one neighboring / additional cell and the first cell for which m-TRP operation is suitable. In some examples, the additional cell may refer to cell with a different PCI than a serving cell. In some examples, the additional cell may refer to cell that is a candidate cell for inter-cell mTRP. In some examples the additional cell may refer to a cell other than serving cell. In some examples, the additional cell may refer to an inter-cell mTRP cell which the UE communities in additional to a serving cell. In block 303, the UE includes the RS ID of the determined RS of the additional cell, and the additional cell’s cell ID of the as part of an RA procedure, performed by the UE towards the first cell. The UE may further determine whether to receive / transmit over at least one channel on the additional cell (i.e. a 2nd cell / neighboring cell) based on the identifier information provisioned during the RACH procedure in block 303. During the RA procedure, the inter-cell m-TRP operation may be confirmed or rejected by the network. In one example embodiment, if the UE were not to receive confirmation, or if it were to receive a rejection of the inter-cell m-TRP operation during the RA procedure, the UE may determine that the RA procedure is completed for the first cell without inter cell m-TRP operation. When the UE completes the RA without inter-cell operation, it communicates with the first cell. If the UE were to receive confirmation of inter-cell m-TRP operation during the RA procedure, the UE may determine that the RA procedure is completed for the first cell with inter cell m-TRP operation (based on the indicated RS of the second cell). The m-TRP operation may comprise detailed information of simultaneous transmission and or reception of different DL / UL channels, e.g.: o simultaneous reception on all DL channels, o simultaneous reception on PUSCH channels only, o simultaneous transmission on all UL channels, o simultaneous transmission on PUSCH, or o any combination of the above. In certain example embodiments, based on the system information received in block 301 (including the support signaling regarding whether various resources [e.g. RSs, TRPs and cells] support inter cell m-TRP operation]) the UE selects at least one resource on the first cell and the additional cell. The selected resources may be, for example: SSBs or CSI-RSs, and the indication of the resources provided during the random access procedure in block 303 may be indicative of the ability (or capability) of the UE to perform at least one of the following communication modes: i. using SSB resources for both simultaneous downlink reception and transmission, ii. using SSB resources for simultaneous downlink reception, iii. using SSB resources for simultaneous uplink transmission (i.e. STxMP, simultaneous transmission, multi-panel), iv. using SSB resources for uplink transmission (no simultaneous uplink) v. using SSB resources for downlink reception (no simultaneous DL), or vi. using SSB resources for downlink reception and uplink transmission. The UE may indicate its ability (or capability) to perform one or more of the above communication modes by including the additional cell information (e.g. PCI and / or DL RS index) in an RA msg.3. For instance: - one field in the MAC CE may carry this information - one field in the MAC CE may indicate whether the inter-cell m-TRP information is present in the MAC CE - one field in the MAC CE may indicate whether the m-TRP operation is for inter-cell or intra-cell. In one example, the inclusion of DL RS associated with a cell other than the first cell may indicate to the network that the UE is able to perform at least one of the above communication modes. In one example, the MAC CE may carry an indication of a PCI value of the inter-cell m-TRP cell (in addition to first cell) or a logical index value of PCIs listed in the received system information (i.e. PCIs that support inter-cell m-TRP cell). In one example a set of RA resources (RACH preambles) may be associated with inter-cell m-TRP indication. In this regard an RA resource pool may be divided between “normal RACH” and “inter-cell m-TRP RACH”. The transmission of an RA preamble selected from the inter-cell m-TRP RACH resource pool may indicate to the network that the UE may provision m-TRP related information as part of the RACH procedure. If the UE selects an RA preamble from the inter-cell m-TRP RACH resource pool, the UE may include a MAC CE in msg.3 of the RA procedure that comprises a field for inter-cell m-TRP information (such as DL RS of an additional cell). In some examples, one or more reference signals (such as SSBs / CSI-RSs) provisioned by a candidate m-TRP cell can be selected by the UE for inter-cell operation. In some examples, the selection of DL RS(s) may be based on a threshold level (e.g. an RSRP threshold) or other criteria. The RSRP threshold signalled in the system information, wherein the RSRP threshold is specific for inter-cell m-TRP operation. The RSRP threshold may be cell specific. In some examples, the network’s indication, to the UE, of supporting inter-cell m-TRP operation may further indicate that the UE is permitted to provide, during / as part of a random access procedure, information on at least one RS of at least one cell that is indicated in the system information (this may be referred as second cell or additional cell) of the cell selected for the random access. In some examples, the RACH configuration, provided to the UE by the network, may provide indication as to whether a cell allows or supports the provision of additional information during an access procedure (i.e. whether m-TRP related information is permitted to be transmitted by the UE during the access procedure). In some examples, the indication of inter-cell m-TRP operation support (i.e. provided in block 301) may comprise at least one cell identifier (e.g. a PCI of an inter-cell m-TRP candidate cell) for which the inter-cell m-TRP operation can be assumed in addition to the current cell (i.e. the cell provisioning the system information). In some examples, one or more reference signals (such as SSB(s) / CSI-RS(s)) provisioned by the candidate m-TRP cell can be selected by the UE for inter-cell operation. In some examples, the indication of inter-cell m-TRP operation support (i.e. provided in block 301) may comprise at least one cell identifier (e.g. PCI of an inter-cell m-TRP candidate cell) and set of reference signals for which the inter-cell m-TRP operation can be assumed in addition to the current cell (i.e. the cell provisioning the system information). In some examples, the one or more reference signals of the set of reference signals (such as SSB(s) / CSI-RS(s)) provisioned by the candidate m-TRP cell can be selected by the UE for inter-cell operation. In some examples, the indication of inter-cell m-TRP operation support (i.e. provided in block 301) may comprise cell identifier pairs (e.g. PCIs of inter-cell m-TRP candidate cell pairs) for which inter-cell m-TRP operation can be assumed for each cell pair. For example, a first cell, celH, may have cell pairs that are cell2 and cell 3. In some examples, if a cell pair is indicated (e.g. in the system information provided in block 301), it may be indicated to the UE that the UE is permitted to initiate a random access procedure on either cell of the pair, and that the UE may indicate at least one RS of the other of the cell pair for inter-cell m-TRP operation (i.e. during the random access procedure). In some examples, if a cell pair is indicated (e.g. in the system information provided in block 301), if the UE initiates a random access procedure on the first listed cell of the indicated cell pair, this may be taken to indicate at least one reference signal of the other of the cell pair for inter-cell m-TRP operation, but not vice versa. I.e. if the UE initiates a random access procedure on the second listed cell of the indicated cell pair, this may be taken as not indicating any RSs of the other of the cell pair for intercell m-TRP operation. In some examples, any information herein related to inter-cell m-TRP may be provided in an RRC message (e.g. a dedicated RRC message) or provided in system information. FIG. 4 schematically illustrates an example of a procedure 400 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. As will be discussed in further details below, in some examples the UE may camp on a cell (i.e. the UE has selected the cell and determined to monitor paging on the cell) and it may determine that the cell quality is above a threshold and hence the UE is not required to perform intra-frequency measurements (measure other cells). Subsequently: upon reading system information in an IDLE mode and determining that the first cell and at least one additional cell support inter-cell m-TRP, the UE may perform measurement on at least one RS of at least one additional cell listed in the system information the UE may indicate at least one RS of the additional cell during an RA procedure. Initially (not shown in FIG. 4), the UE may select a first cell hosted by the BS, and perform measurements on RSs from the first cell. The UE may then determine that performance of measurements on RSs from other cells is not required, wherein such a determinisation may be based on the measurements of the RSs from the first cell (such as whether the measurements results of the RSs of the first cell meet a criteria - e.g. a threshold RSRP). In block 401, the UE receives, from the BS, first information 402 that indicates whether one or more resources 403 support inter-cell m-TRP operation, wherein the one or more resources comprise: one or more cells (i.e. of one or more base stations, one of which may be the BS 120), one or more TRPs (i.e. of one or more cells), and / or one or more reference signals, RSs (i.e. of one or more TRPs of one or more cells). In this regard, the first information provides support information (which may be referred to as inter-cell m-TRP related information for random access) that the UE can use to determine, prior to the UE performing a random access procedure, which resources support inter-cell m-TRP operation and hence which resources the UE could select and seek to use for inter-cell m-TRP operation. For instance, the first information may comprise: a list of neighbouring cell IDs and RS IDs of neighbouring cells that can be used, in conjunction with the first cell and an RS of the first cell, for inter-cell m-TRP operation across the first and second cells. The first information may be transmitted by the BS via: system information, or a radio resource control, RRC, message. The first information may comprise an indication of at least one of the following: whether one or more cells 122 support inter-cell m-TRP operation; whether a first cell 122_1 (which the UE seeks to access in a random access procedure 409 as discussed further below) supports inter-cell m-TRP operation; whether one or more second cells 122_2 support inter-cell m-TRP operation with the first cell 122_1; whether one or more TRPs of the first cell can be used with one or more second TRPs of one or more second cells for inter-cell m-TRP operation; or whether one or more RSs (e.g. SSB or Channel State Information, CSI, RS) of the first cell can be used with one or more RSs (e.g. SSB or CSI-RS) of one or more second cells for inter-cell m-TRP operation. The first information may comprise an indication of at least one of the following: one or more cell identifiers (e.g. PCI of a second cell); one or more TRP identifiers; and one or more RS identifiers (e.g. of RSs of a second cell). The first information may comprise an indication of at least one of the following: at least one set of cells, wherein each cell is associated with a set of RSs that are configured to serve as a Quasi Co-Location, QCL, reference; at least one set of TRPs of the first cell, wherein each TRP is associated with a set of RSs that are configured to serve as a QCL reference; one or more sets of TRPs of one or more second cells, wherein each TRP is associated with a set of RSs that are configured to serve as a QCL reference; a set of TRPs comprising TRPs from differing cells, wherein each TRP of each cell is associated with a set of RSs that are configured to serve as a QCL reference. Each QCL reference may be a QCL reference for use by the UE to perform reception, Rx, and / or transmission, Tx, based on the reference signal. In some examples it may refer to simultaneous Rx and / or Tx across multiple TRPs of multiple cells ( e.g. first cell and at least one another cell). The first information may also comprise an indication that the UE is permitted to transmit second information 408 (as discussed further below in block 407) to the BS during a random access procedure. Such an indication may be explicit or implicit (i.e. the indication is implicitly provided to the UE by virtue of the mere BS’s transmission of the first information itself). In block 404, the UE determines at least one resource, of the one or more resources indicated in the first information, that the UE is capable of using in an inter-cell m-TRP operational mode 406. In particular, in this regard, the UE determines whether a first cell 122_1 and at least one other cell 122_1 support an inter-cell m-TRP operational mode. For instance, where the first information comprises list of IDs of neighbouring cells 122_2 and / or IDs of RSs 405_2 of neighbouring cells that can be used for inter-cell m-TRP operation (i.e. with a first cell 122_1 and RSs of the first cell), the UE may select a particular neighbouring cell ID and / or a particular RS ID of a neighbouring cell that is suitable for / a candidate for use in an inter-cell m-TRP operational mode 406. The UE’s determining of the one or more resources may comprise at least one of: determining at least one second cell that supports inter-cell m-TRP operation with the first cell; determining at least one TRP of at least one second cell that supports intercell m-TRP operation with the first cell; and determining at least one RS of at least one second cell that can be used by the UE to perform inter-cell m-TRP operation with the first cell. The UE’s determining of the one or more resources may comprise selecting at least one identifier from one or more identifiers indicated in the first information 402. In block 404A, responsive to determining that the first and second cells support an inter-cell m-TRP operational mode, the UE performs measurements of RSs from the second cell. In block 407, the UE transmits second information 408 to the BS during a random access procedure 409 to a first cell 122_1 that is hosted by the BS. The second information provides an indication of at least one RS 405_2 of the RSs from the second cell. The second information (i.e. its content - namely which at least one RS it provides an indication of) is based at least in part on the RS measurements of block 404A. In this regard, the at least one RS 405_2, that the second information provides an indication of, may be at least one RS that is selected from the second cell’s RSs based on the measurements of the RSs from the second cell carried out in block 404A. For instance, RSs from the second cell whose measurements results meet a criterion (e.g. a threshold signal strength / quality) may be selected as the at least one RS 405_2 to be indicated in the second information. In some examples, the second information may be received whilst the apparatus is in an idle mode. The second information may comprise an indication of at least one identifier selected by the UE from one or more identifiers indicated in the first information 402. In some examples, during the random access procedure but prior to the UE’s transmission of the second information in block 407, the UE may transmit, to the BS, an indication that the UE will transmit the second information to the BS during the random access procedure. In this regard, the UE may have been previously configured with a set of RA resources (e.g. RACH preambles), wherein: a first subset of RA resources has been associated with indicating that the apparatus will transmit second information to the second apparatus during the random access procedure, and a second subset of RA resources has been associated with indicating that the apparatus will not transmit second information to the second apparatus during the random access procedure. The UE can thereby indicate that it will transmit the second information to the BS during the random access procedure by selecting and using a RA resource form the first subset of RA resources. In block 410, the UE receives third information 411 from the BS that is indicative of whether the UE is to operate in the inter-cell m-TRP operational mode 406. The third information is based at least in part on the second information. In this regard, upon receipt of the second information, the BS may determine whether or not to permit the UE to operate in the inter-cell m-TRP operational mode 406. The BS may then send third information indicative of the whether or not it permits the UE to operate in the inter-cell m-TRP operational mode. The third information may be received from the BS either: during the random access procedure (as indicated by 409’), or after completion of the random access procedure (as indicated by 409). The UE may determine one or more modes of inter-cell m-TRP operation that is it capable of performing and the third information may comprise an indication of the determined one or more modes of inter-cell m-TRP operation. The UE’s determinisation of inter-cell m-TRP operational modes it is capable of performing may be based, not least for example on one or more of: the resources indicated in the first information, measurements of signal strength / quality of RSs associated with such resources, as well as hardware capabilities of the UE (not least such as STxMP capabilities).

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. The component blocks 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. 5 - embodied in a UE or gNB).

Implementation of the controller 11 can be as controller circuitry. The controller 11 can be implemented in hardware alone, have certain aspects in software including firmware alone or can be a combination of hardware and software (including firmware). 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. The processor 12 is configured to read from and write to the memory 13.

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. 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.

These computer program instructions can also be stored in a computer-readable medium that can direct a programmable apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the blocks. The computer program instructions can also be loaded onto a programmable apparatus to cause a series of operational actions to be performed on the programmable apparatus to produce a computer-implemented process such that the instructions which are performed on the programmable apparatus provide actions for implementing the functions / functionality specified in the blocks. Various, but not necessarily all, examples of the present disclosure can take the form of a method, an apparatus, or a computer program. Accordingly, various, but not necessarily all, examples can be implemented in hardware, software or a combination of hardware and software. Various, but not necessarily all, examples of the present disclosure are described using flowchart illustrations and schematic block diagrams. It will be understood that each block (of the flowchart illustrations and block diagrams), and combinations of blocks, can be implemented by computer program instructions of a computer program. These program instructions can be provided to one or more processor(s), processing circuitry or controller(s) such that the instructions which execute on the same create means for causing implementing the functions specified in the block or blocks, i.e. such that the method can be computer implemented.

Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation. Features described in the preceding description can be used in combinations other than the combinations explicitly described. Although functions have been described with reference to certain features, those functions can be performable by other features whether described or not. 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. For instance, it will be understood that the above described aspect could be combined, e.g. a UE / BS may be configured to employ one or more of the: inference, data collection, training and monitoring operational modes. 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”. 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. 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. 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.” 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. 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. 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. 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. 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. 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). 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. 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. The examples of the present disclosure and the accompanying claims can be suitably combined in any manner apparent to one of ordinary skill in the art. Separate references to an “example”, “in some examples” and / or the like in the description do not necessarily refer to the same example and are also not mutually exclusive unless so stated and / or except as will be readily apparent to those skilled in the art from the description. For instance, a feature, structure, process, block, step, action, or the like described in one example may also be included in other examples, but is not necessarily included. Each and every claim is incorporated as further disclosure into the specification and the claims are embodiment(s) of the present disclosure. Further, while the claims herein are provided as comprising specific dependencies, it is contemplated that any claims can depend from any other claims and that to the extent that any alternative embodiments can result from combining, integrating, and / or omitting features of the various claims and / or changing dependencies of claims, any such alternative embodiments and their equivalents are also within the scope of the disclosure.
