  • Some of these different types of devices may be deployed in very large numbers, for example low complexity devices for supporting the “The Internet of Things”, and may typically be associated with the transmissions of relatively small amounts of data with relatively high latency tolerance.
  • Other types of device for example supporting high-definition video streaming, may be associated with transmissions of relatively large amounts of data with relatively low latency tolerance.
  • Other types of device may be characterised by data that should be transmitted through the network with low latency and high reliability.
  • a single device type might also be associated with different traffic profiles / characteristics depending on the application(s) it is running. For example, different consideration may apply for efficiently supporting data exchange with a smartphone when it is running a video streaming application (high downlink data) as compared to when it is running an Internet browsing application (sporadic uplink and downlink data) or being used for voice communications by an emergency responder in an emergency scenario (data subject to stringent reliability and latency requirements).

  • the network 6 includes a plurality of base stations 1 connected to a core network 2. Each base station provides a coverage area 3 (i.e. a cell) within which data can be communicated to and from communications devices 4. Although each base station 1 is shown in Figure 1 as a single entity, the skilled person will appreciate that some of the functions of the base station may be carried out by disparate, inter-connected elements, such as antennas (or antennae), remote radio heads, amplifiers, etc. Collectively, one or more base stations may form a radio access network.

  • An example of such an obstacle is motorcycle 403, which is at present blocked from view (i.e. no clear line of sight (LOS)) of the base station 401 by tall building 404.
  • the base station 401 therefore may not be aware of the motorcycle’s 403 presence so as to signal this to the car 402 until it is too late, and the car 402 can no longer avoid a collision with the motorcycle 403.

  • the sensing entity 405 is itself able to transmit sensing signals and receive reflected sensing signals, and to exchange these with the base station 401. Because the sensing entity 405 has a good LOS to the motorcycle 403 which is not obstructed by the tall building 404, it is able to sense its presence and report this to the base station 401, so that the base station 401 is able to warn the car 402 about the motorcycle 403.
  • FIG. 6A shows an example of a TRP-TRP bistatic mode scenario, in which a first TRP 611 transmits a sensing signal 614 towards an (active or passive) object or device (such as bus 612) which then reflects 615 the sensing signal to a second TRP 613.

  • the transmitter and receiver of the sensing signals are both within the same equipment/location/site, whereas in bistatic scenarios such as those shown in Figures 6A, 6C, 6D, and 6E, the transmitter and receiver of the sensing signals are geographically separated (i.e., non-co-located).
  • the network needs to determine a set of UEs to use in the ISAC process, because - as can be understood with respect to Figure 4 and the discussion thereof above for example - having just a relatively small number of fixed base stations performing sensing may not be sufficient to build up an acceptable map of a particular environment or area of interest.
  • there could be many UEs in such an area of interest which could be a certain environment or geographical area or the area around a particular target object.
  • some of these UEs may be suitable for participation in the ISAC operation, but others may not.
  • the preferable UEs for ISAC operation are those that are close to the sensing region of interest, since these UEs will provide results with better accuracy (as the signal to noise ratio (SNR) of the sensing measurements will be higher).
  • SNR signal to noise ratio
  • a technical issue to solve therefore is how the network is able to choose an appropriate set of UEs to use in I SAC operation, particularly when such UEs are in IDLE or INACTIVE mode and thus their capabilities and other information is unknown to the network.
  • Embodiments of the present disclosure seek to provide solutions to such a technical issue.

  • embodiments of the present technique therefore propose that, in order to find a suitable set of UEs (which may include IDLE / INACTIVE mode UEs) to take part in sensing operations, the network sends a sensing request message to such UEs.
  • UEs that can take part in the sensing operations respond to the sensing request message, preferably indicating information that allows the network to choose a set of UEs to take part in the sensing operation.
  • the sensing request message is a WUS, carried by a SIB, or otherwise broadcast or transmitted by the gNB in any appropriate manner.
  • the sensing request message indicates that the UE responds to the sensing request message with its sensing capability.
  • the information relating to the ability of a communications device to perform sensing operations may comprise a sensing capability of that communications device.
  • Example sensing capabilities that the sensing request message may indicate the UEs are to respond with include (but are not limited to):
  • the sensing capability may comprise one or more of a capability of the communications device to perform one or more beamforming techniques, a bandwidth over which the communications device is able to perform channel measurement, and one or more types of sensing reports the communications device is able to transmit to the wireless communications network.
  • the UEs that receive the sensing request message and are able to take part in the sensing operations will then report their ISAC capability in the response signal to the sensing request message.
  • the gNB will have stored capability information for such UEs already.
  • the network e.g. the gNB/TRP or a sensing management function (SeMF) in the core network
  • the network may then choose appropriate UEs with the desired sensing capability to take part in ISAC operations.
  • the sensing request message may request that only those UEs with certain sensing capabilities respond.
  • the sensing request message may indicate that only communications devices with a specified sensing capability are to transmit a response to the sensing request message to the infrastructure equipment.
  • a set of sensing capabilities may be defined, signalled to UEs, and/or preconfigured (e.g., in the specifications). Then, the UEs which support and are able to be involved in the sensing functions select one or more of the supported capabilities. Since only the UEs with suitable capabilities would respond, the number of response messages is limited, and so the overall procedure is made more efficient and interference is reduced. For example, such arrangements ensure that the initial access/physical random access (PRACH) channel is not overloaded in response to a sensing request.
  • PRACH initial access/physical random access
  • the sensing request message could additionally or alternatively request that only UEs with the correct orientation (in the direction of the target) should respond. This may be useful if the gNB does not transmit the sensing request message (or other type of sensing request message) only in the direction of the target or target sensing area.
  • the sensing request message could additionally or alternatively request that only UEs in a certain location (e g. close to the target) should respond.
  • UEs are able to determine their location by several different means. For example, the UEs could determine their location by:
  • PRACH set 1 there are two sets of PRACH resource assigned: PRACH set 1 and PRACH set 2.
  • Legacy UEs e.g. UEs not requested to be involved in sensing operations who may wish to initiate a connection to the network for the purposes of transmitting uplink data
  • sensing UEs e.g. UEs which are to respond to a received sensing request message are assigned to PRACH set 2.
  • PRACH set 2 Even if there is overload on the PRACH set 2 resources (due to the sensing UEs), the normal UEs can continue to use the PRACH set 1 resources without interruption.
  • PRACH partitioning In this case, in a set of PRACH resources, some parts are allocated for sensing purposes and the other resources are for the legacy random access operation.
  • the resources here can be referred to resource in terms of time and frequency resources and/or distinct sets of RACH preambles. For example, there are 64 possible preambles.
  • the first 10 may be allocated for sensing purposes and the rest may be allocated for the legacy random access process.
  • RAR also known as Msg2
  • the received responses may be received from the subset of communications devices as a first message of a random access (RACH) procedure, and the infrastructure equipment may be configured to transmit, to a selected one or more of the subset of communications devices, a random access response, RAR, as a second message of the random access procedure.
  • RACH random access
  • this RAR may indicate that the selected communications devices (i.e. those which receive the RAR) are to perform the sensing operations, or may indicate that the selected communications devices (i.e. those which receive the RAR) are to continue the RACH procedure by transmitting a Msg3.
  • This operation is in contrast to the normal/legacy paging process, in which the UE continues the PRACEI process until a response is received from the network, where here, the UE is thus able to simply go back to sleep upon not receiving a RAR.
  • This can be signalling in the sensing request (e.g. paging) message, where such signalling indicates that if a new PRACH (e.g. a sensing PRACH) is used, then there is a time window during which a RAR can be received - and if no RAR is received by a UE during this time window, the UE knows that it has not been selected, does not need to continue with the sensing request procedure, and so can safely go back to sleep.
  • a new PRACH e.g. a sensing PRACH
  • the mode of operation according to such arrangements saves on RAR resources when there are many inactive UEs that could take part in the sensing service.
  • the network e.g. the gNB or SeMF
  • RAR messages are then only sent to that subset of UEs.
  • a RAR is transmitted on the DL-SCH transport channel (i.e. PDSCH).
  • the CRC of the PDCCH that allocates the PDSCH containing the RAR(s) for sensing may be scrambled with a Sensing-Radio Network Temporary Identifier (Se-RNTI).
  • Se-RNTI Sensing-Radio Network Temporary Identifier
  • the UE uses that Se-RNTI to decode the gNB’s response to the transmitted RACH preamble for sensing.
  • the sensing -RNTI is also to be used to decode the PDCCH of the sensing -response message (in PDSCH). Hence, only a UE that has provided a RACH preamble for sensing can decode the RAR message.
  • UEs which are expecting to receive a RAR message for sensing are expected to monitor for the RAR message with a predefined minimum distance (e.g., time gap) from the last RACH resource for sensing to the start of monitoring the RAR message for sensing.
  • the time offset is significantly larger than the legacy time gap, to provide the gNB with sufficient time to evaluate and select UEs to be involved in the sensing operations.
  • the time gap can be in the order of multiple subframes / slots.
  • the UE is also expected to monitor for the RAR message within a time window. Within the time window, the UE monitors for a control resource set (CORESET) configured for receiving a PDCCH allocating the PDSCH carrying a RAR message.
  • CORESET control resource set
  • the starting time of the time window for monitoring for a RAR message for sensing can be the first symbol of the aforementioned CORESET.
  • this time offset and time window may be indicated within the sensing request message, which thus informs the UE that the monitoring period for the RAR is not the same is in a legacy RACH procedure.
  • the sensing request message may comprise an indication of a time window during which the RAR is to be transmitted to the selected communications devices.
  • Standby The UE can go to sleep, but should monitor the paging channel more frequently as the UE might be requested again to take part in the sensing procedure in the near future.
  • the sensing request message may indicate that UEs that had previously responded within a time window T respom:e do not need to respond to the current sensing request message.
  • the network could send a sensing request message at a first time i and receive responses from multiple UEs, where some of those UEs are inappropriate for the sensing service (for example, they do not have the appropriate sensing capability or their location is not suitable).
  • the network would choose those UEs that are suitable for the sensing service at around T i (and not respond to the unsuitable UEs). The number of UEs chosen may be insufficient at Ti.
  • the network therefore then sends a further sensing request at a second time T 2 to find further suitable UEs. In sending this further sensing request, the network does not want UEs that were considered unsuitable at Ti to respond.
  • the network sets T reS ponse > T 2 - TI and UEs that responded at Ti do not send a sensing response at T 2 . In this manner, the network only receives “fresh” responses at T 2 .
  • the response from the UE to the sensing request message may be transmitted:
  • the gNB then processes the information (such as performing selection of the UEs that are to participate in the sensing operations), and then sends the reply to the selected UEs;
  • the infrastructure equipment may be configured to select, based on the received responses, one or more of the subset of communications devices to perform the sensing operations, and to transmit, to the selected communications devices, an indication that the selected communications devices are to perform the sensing operations.

  • a UE with low battery may not respond to a standard sensing request message (in order to save battery life), but would respond to a mandatory / regulatory sensing request (for example, associated with monitoring a public safety incident).
  • WUSs can wake up UEs to take part in sensing operations, as described above. UEs are able to monitor for a WUS with a lower power consumption than for monitoring other channels. Use of a WUS to indicate sensing operations would hence reduce UE power consumption (in comparison to other signalling methods).
  • the WUS may in some implementations comprise a single bit that indicates whether that WUS is for sensing purposes or not.
  • the choice of which UE to page (or send another type of sensing request message) is based on UE type.
  • the infrastructure equipment may be configured to determine that the sensing request is to be transmitted to the plurality of communications devices based on a type of each of the plurality of communications devices. For example, the following types of UE may be identified:
  • sensing service e.g. a service for vehicles that allows them to see around comers in intersections. Such UEs may need to provide sensing measurements in order to be able to be part of the sensing service (i.e. a condition of them receiving the sensing results is that they provide some of the raw data that allows the sensing results to be obtained); and
  • the gNB may decide to send sensing request messages to UEs according to a priority list, which may for example be ordered based on UE type in the manner indicated by the list above.
  • the type of each of the plurality of communications devices may be one of a plurality of types of communications device, and wherein each of the plurality of types of communications device may be associated with one of a plurality of preconfigured priority levels.
  • the gNB may prefer to send sensing request messages to city-owned UEs in preference to incentivised UEs since the city-owned UEs would be in a known location and there would be no charge for using such UEs. If there were an insufficient number of such UEs available, the gNB would consider sending sensing request messages to emergency worker UEs, then those that are part of the sensing service, and then incentivised UEs as a last resort, for example.
