Definitions

  • the present disclosure relates generally to communications, and more particularly to communication methods and related devices and nodes supporting wireless communications.
  • MDT minimization drive test reporting has been used in 3rd Generation Partnership Project 3 GPP cellular communication since Release 9 and was recently extended to New Radio NR in 3 GPP Release 16.
  • the purpose of MDT is for the Use Equipment UE to store information about different measurements that the UE may perform both in IDLE mode and in connected mode. Typical measurements that a UE may log include the qualities of the cells the UE traverses when moving, and/or statistics about transmission delays the UE experiences, or events such as Radio Link Failure RLF or handover failures.
  • Such reports may then be requested by the network and used for different purposes, such as coverage improvement/optimization, mobility improvement/optimization, capacity improvement/optimization, QoS verification, and ultimately SON (self-organizing network).
  • MDT includes 2 modes: Logged MDT; and Immediate MDT.
  • Logged MDT the UE is configured to perform measurements while being in RRC IDLE mode and/or in RRC INACTIVE mode, including measurement of neighbouring cells, location, timestamps, etc.
  • Immediate MDT the UE is configured to perform measurements while in connected mode.
  • Both modes are configured by the 0AM (Operations and Management), and they can be requested in the form of signaling-based MDT or management-based MDT.
  • the MDT is requested by the 0AM for a specific UE, whereas for the management-based MDT the eNB/gNB selects an arbitrary UE.
  • the 0AM just indicates to the Radio Access Network RAN whether MDT is allowed (e.g., on the basis of roaming status, user consent, etc.) for this selected UE.
  • the MDT can also be area specific, e.g., the UE can be configured to perform logged MDT as long as it is located within such a configured area, wherein the area can span multiple cells possibly belonging to different PLMNs.
  • the 0AM can indicate to the RAN an area scope, so that if the UE connects to a cell which is part of such area scope, the RAN can configure the UE for immediate MDT accordingly.
  • the UE may also report to the network other useful information that the network can use for various SON improvements/optimizations, such as mobility improvements/optimizations, RACH improvements/optimizations, coverage improvements/optimizations, etc., and more in general user experience.
  • the UE may be required to store information about possible Radio Link Failure RLF events experienced, handover failures HOFs, connection establishment failures CEFs, successful random access RA procedures, mobility history (i.e., including the visited cells). This information can be exchanged between neighbouring cells as well as with Operation and Management O&M.
  • the UE Upon storing the above information, the UE signals the availability of certain MDT/SON data to the network. Such availability flag can be conveyed in various Radio Resource Control RRC messages, such as RRCSetupComplete during the RRC connection establishment procedure, RRCReconfigurationComplete during RRC reconfiguration procedure, RRCReestablishmentComplete during RRC connection re-establishment procedure, RRCResumeComplete during RRC connection resume procedure, and also in the UEInformationReponse.
  • RRCSetupComplete during the RRC connection establishment procedure RRCReconfigurationComplete during RRC reconfiguration procedure
  • RRCReestablishmentComplete during RRC connection re-establishment procedure
  • RRCResumeComplete during RRC connection resume procedure
  • the network can decide at a later point in time to retrieve the MDT/SON information from the UE by sending to the UE a UEInformatioRequest and explicitly indicating the report type to which the network is interested in, e.g., logMeasReportReq.
  • the UEInformationRequest message is shown below in Table 1, and the related field definition are shown below in Table 2.
  • the network can request various elements of MDT/SON information, such as mobility information, RLF information, logged measurement reports, etc.
  • the UE Upon receiving such a request, the UE replies with a UEInformationResponse message including the information explicitly requested by the network.
  • the UEInformationResponse message may be quite big and all the information that the UE has stored might not fit into a single UEInformationResponse message. That is because the UE can store MDT/SON information for up to 48 hours and in some cases, such as the case of logged measurements, the report to be included in the UEInformationResponse might be very big.
  • the UE when it is configured for logged measurements, it shall store a bunch of information related to the cells visited while in IDLE mode as well as information related to whatever the UE has measured from the surrounding radio environment, such as neighbouring cells or radio stations possibly belonging to different Radio Access Technologies RATs, such as New Radio NR, Long Term Evolution LTE, Bluetooth, Wifi, etc.
  • Radio Access Technologies RATs such as New Radio NR, Long Term Evolution LTE, Bluetooth, Wifi, etc.
  • the UE can report as part of one UEInformationResponse message just one sample of a given report, e.g., just one RRC segment of a stored logMeasReport, and at the same time indicate to the network that there are additional samples available for such report, i.e., that there are additional RRC messages to be transmitted associated with such report. In this way, the network can keep scheduling those remaining samples if needed.
  • Table 3 shows the UEInformationResponse for the case of a logged measurement report.
  • LBT listen before talk
  • LBT sub-band i.e., the frequency part with bandwidth equal to LBT bandwidth
  • a device is only allowed to transmit on the sub-bands where the medium is sensed as free.
  • LBT procedures may have to be performed by both the base station, and the UE, whenever they intend to transmit something on the unlicensed spectrum, and that is also applicable to any UL/DL transmission, i.e., both data, and layer-1/2/3 control signaling.
  • 3 GPP supports the classical dynamic scheduling approach in which each UL Medium Access Control MAC Protocol Data Unit PDU is explicitly scheduled by the gNB via Physical Downlink Control Channel PDCCH signaling.
  • a scheduling scheme may have a drawback of increasing the channel occupancy in the unlicensed spectrum due to PDCCH signaling in the downlink DL.
  • an uplink UL Medium Access Control MAC Protocol Data Unit PDU is scheduled by PDCCH, such MAC PDU may subject to LBT and hence it might not be transmitted. That in turn may require yet another Uplink UL grant conveyed in PDCCH. Therefore, latency may also be impacted.
  • autonomous UL a special flavor of semi-persistent scheduling, also known as “autonomous UL”.
  • the autonomous UL grant resembles the configured grant with the difference that the network can indicate the number of consecutive slots within a configured grant period that the UE can use for UL transmissions.
  • autonomous UL there is no relationship between Transmission Time Interval TTI and Hybrid Automatic Repeat Request HARQ process Identifier ID. This allows the UE to autonomously select the HARQ process to transmit on a given TH.
  • the UE can have the possibility to immediately re-select again the same MAC PDU and try to transmit it in the next TTI, e.g., before other MAC PDUs of lower priorities associated with other HARQ process Identifiers IDs.
  • the reports may need to be transmitted using multiple uplink messages, requiring multiple requests and corresponding LBT procedures.
  • it may be useful to reduce signaling overhead and/or delay/failure resulting from requests and/or LBT procedures.
  • a method of operating a communication device is provided.
  • a request message is received from a network node, wherein the request message indicates autonomous transmission of information collected by the communication device over multiple transmission occasions.
  • Response messages are transmitted autonomously over multiple transmission occasions responsive to receiving the request message from the network node.
  • Each response message includes a respective portion of the information collected by the communication device, and each of the response messages is transmitted over a respective one of the multiple transmission occasions.
  • a method of operating a network node is provided.
  • a request message is transmitted to a communication device, wherein the request message indicates autonomous transmission of the information collected by the communication device over multiple transmission occasions.

  • the NW may decide to allow the UE to autonomously send the remaining sample, since the transmission of additional request messages for each and every sample may increase the channel occupancy of the unlicensed spectrum. Therefore, this decision may be based on the level of RSSI/channel occupancy experienced by the radio base station and by the UE. For example, if the channel occupancy is high, the network may decide to postpone the transmission of request message for the MDT/SON report, and then once the channel occupancy goes below a certain value, the network may send to the UE a request message indicating that the UE shall transmit autonomously all the remaining samples/bytes in any of the subsequent UL grants.
  • the network may request the UE to stop transmitting such remaining samples/bytes until the channel occupancy decreases between a certain level.
  • the above decision might depend on the type of the MDT/SON report to be received. If that is of high priority, or if such type of report has not been received for a long time, the network may decide to request the UE to autonomously send the concerned report. That is because avoiding sending the “request message” has only an advantage in terms of reduced latency, i.e. transmitting a request message in the unlicensed spectrum implies performing the LBT procedure whose outcome might be to drop or postpone the transmission of such request message.
  • the above decision may be based on the amount of samples/bytes the UE has stored.
  • the network may configure the UE to autonomously transmit those remaining samples, otherwise if it is little information the network may just request those remaining samples explicitly by sending the “request message”. That is because the network may decide to provide a configured grant for the transmission of the remaining samples, but if the UE just has few data to transmit it might not be worthwhile to configure a configured grant.
  • the gNB may carry out operation (203), i.e. it may determine the proper size of one or more UL grants to convey the various samples of the MDT/SON report. That can be determined on the basis of the number of samples/bytes that the UE has stored related to one or more MDT/SON reports available and signaled in the availability message. Such information can be combined with the status of the UE UL buffer, e.g. from the latest received BSR or any other UL buffer estimation method available at the gNB.
  • one outcome of operation (203) could be that if the UE is enabled to autonomously send the various samples in operation (202), the gNB may provide a configured grant, i.e. a combination of time/frequency transmission occasions, of proper size to allow the UE to transmit the various stored samples.
  • the gnB may send a re-activation command containing a new grant size, i.e. a new TBS/MCS (Transport Block Size and/or Modulation and Coding Scheme), for the configured grant.
  • a new grant size i.e. a new TBS/MCS (Transport Block Size and/or Modulation and Coding Scheme
  • the grant size may be readjusted in case the UE signals in the availability message that new data has been stored for a given report compared with last transmission of the availability message, or in case the UE signals a larger number of samples/bytes for a given report compared with last transmission of the availability message.
