  • base station enhanced node B (eNB)
  • g node B gNB
  • terminal and “user equipment (UE)” may be interchangeably used.
  • the xSS configuration information may include the beam ID of a beam carrying an SS to be measured for RLM (or corresponding time, frequency, and resource information), or the SS location information on the time and frequency of the SS resource to be measured in the corresponding beam.
  • T_out or T_in is the time duration required for generating one OOS or IS indication.
  • N is used to specify the number of beams for a case where the measurement result is higher than the threshold among the per-beam measurement results during one T_out or T_in. That is, in the case of OOS determination, if the measurement result is above the threshold for N or more beams, this is not OOS. In the case of IS determination, if the measurement result is above the threshold for N or more beams, this is IS.
  • the SS sample is accumulated using the BRS OOS determination method of the disclosure, and the aRS sample is further accumulated to the cumulative SS value when the aRS is transmitted and measured.
  • the measurement value for the aRS is linearly combined with the cumulative value for the SS.
  • an OOS indication is sent to the RRC without further consideration of the aRS.
  • measurement values for the aRS are further considered. That is, if the measurement result for the aRS is less than or equal to the given threshold, an OOS indication is sent to the RRC and otherwise an IS indication is sent to the RRC.
  • the measurement values for the aRS are linearly combined with each other, and the measurement values for the SS are accumulated between the SS measurement values as in the first BRS OOS determination scheme of the disclosure.
  • an index may be assigned to each combination in advance and the network may specify a corresponding rule.
  • Table 1 Such an example is shown in Table 1 below.
  • FIG. 8 depicts a case where the base station transmits information on the offset value set for a specific DL TX beam as system information and the terminal uses this information whenever a DL TX beam set is configured according to an embodiment of the disclosure.
  • the RLF timer can be started or stopped when consecutive OOS or IS indications are sent from the physical layer (PHY) to the RRC. If only one RS is configured, or if only one RS has priority over time without change although two RSs are configured, RLM and RLF operations may be performed by inheriting the RLF parameters of the corresponding RS. However, when plural RSs are configured, if the RLM RS is changed from the previous RS to a new RS, it is necessary to determine whether to apply the RLF parameters associated with the new RS after inheriting the state of the RLF parameters associated with the previous RS, or whether to apply the RLF parameters associated with the new RS after resetting the state of the RLF parameters associated with the previous RS.
  • the remaining CSI-RS beams share the same channel state (OOS) as the SS, and T_IS for SS IS determination will be longer than T_IS for CSI-RS IS determination.
  • OOS channel state
  • the network may instruct the terminal to inherit the state of the existing parameters.
  • the network may instruct the terminal to reset the state of the existing parameters.
  • the terminal has started the RLF timer according to the OOS indications for the SS. Thereafter, when the CSI-RS is configured, the RLM state (timer value) may be inherited or be reset. When the timer value is inherited, the RLF timer is run until the CSI-RS generates a given number of IS indications by continuously applying the SS RLF timer value or until the timer value expires.
  • the terminal 1605 measures the SS in the assigned bandwidth part (at operation 1629), and feeds the measurement result back to the base station 1610 (at operation 1631).
  • the base station 1610 may configure the CSI-RS (at operation 1633). If there is no SS in the assigned bandwidth part, the terminal may measure the SS in the cell or bandwidth part associated with initial RRCConnection and send the measurement information to the base station. Alternatively, the base station can configure the CSI-RS without referring to SS measurement feedback. This CSI-RS will be used in the assigned bandwidth part.
  • the terminal stops the timer. If a preset number of consecutive OOS indications (including inherited ones) are generated from the switched active BWP, the terminal keeps the timer running.
  • the controller 2120 may be a circuit, an application specific integrated circuit, or at least one processor.
  • controller 2120 may control the proposed operations to report a radio link problem to the higher layer according to the embodiments of the disclosure.
  • the storage 2130 may store at least one of information transmitted or received through the transceiver 2110 and information generated by the controller 2120.
  • the base station may transmit a command message to instruct the terminal to monitor, when a specific BWP is configured for the terminal, only the RS corresponding to the frequency range of the configured BWP or the RSs dedicated to the configured BWP among the RSs set as the RLM-RS.
  • This signaling is described in more detail.
  • the base station configures the RLM-RS for the terminal, it can indicate an association between the RS and a bandwidth part (BWP). Based on the RS-BWP association the terminal can use only the RLM-RS associated with the currently active BWP for the RLM operation.
  • ASN.1 level signaling for this is as follows.
  • the RLM-RS list created by the base station is a set of RLM-RSs, and each RLM-RS can indicate the RS type (SSB or CSI-RS).
  • Each RLM-RS may include an index of the BWP where the RLM-RS is to be activated. If the SSB is used for RLM, the RS can be specified by the index of the SSB operated by the serving cell. If the CSI-RS is used for RLM, some of the CSI-RSs configured for beam management of the SpCell can be used as the CSI-RS for RLM. To refer to this, the predefined CSI-RS resource ID may be used to designate the CSI-RS for RLM. The CSI-RS designation can be transmitted together with the time-frequency location information and repeated information of the corresponding CSI-RS.
  • These parameters can be delivered via a RRC message, MAC CE, or DCI.
  • the following shows a case where the parameters are included in SpCell configuration of a RRC message.

Abstract

L'invention concerne un procédé de communication et un système destinés à faire converger un système de communication de 5ème génération (5G) pour prendre en charge des débits de données supérieurs dépassant ceux d'un système de 4ème génération (4G) à l'aide d'une technologie pour l'Internet des objets (IoT). La présente invention peut être appliquée à des services intelligents basés sur la technologie de communication 5G et la technologie liée à l'IoT, comme l'habitation intelligente, le bâtiment intelligent, la ville intelligente, la voiture intelligente, la voiture connectée, les soins de santé, l'enseignement numérique, le commerce de détail intelligent, les services de sécurité et de sûreté. Le procédé comprend les étapes consistant à recevoir un message de gestion des ressources radioélectriques (RRC) comprenant des premières informations associées à un signal de référence pour une surveillance de liaison radio (RLM) et des secondes informations associées à un seuil pour la RLM, à surveiller une qualité de liaison radio d'au moins un signal de référence indiqué par les premières informations, à comparer la qualité de liaison radio du ou des signaux de référence au seuil et à indiquer un état synchronisé ou désynchronisé à une couche supérieure du terminal suivant le résultat de comparaison.
