BLACKPIN INC.

A Method and Apparatus for sidelink positioning is provided. The method includes receiving a SystemInformationBlock12 in a first cell, and transmitting to a type1 UE either a SL MAC CE or a first sidelink signal or a second sidelink signal. The SystemInformationBlock12 includes a SL-ConfigCommonNR and a SL_Pos_ConfigCommon. The SL_Pos_ConfigCommon includes a one or more Sl_Pos_ResourcePool IEs. The first sidelink signal is transmitted on a second resource pool. The second sidelink signal is transmitted on a third resource pool. The first sidelink signal is Synchronization signal or PSBCH and the second sidelink signal is PRS. The first resource pool is configured by a first SL-ResourcePool IE in SystemInformationBlock12. The second resource pool is configured by a second SL-ResourcePool IE in SystemInformationBlock12. The third resource pool is configured by a SL_Pos_ResourcePool IE in the RRCReconfigurationSidelink. The SL MAC CE is transmitted on a first resource pool.

A method and apparatus for positioning in a mobile communication system are provided. Method for positioning includes receiving a first type1 assistance data, receiving a type2 assistance data, determining whether the second type1 assistance data is valid, receiving a RRCRelease, selecting a first cell, transmitting positioning SRS in RRC_INACTIVE, stopping transmission of SRS when a RRC message including a terminal identifier is received in the first cell and transmitting a specific LPP message.

A solution for monitoring low power receiver signal in RRC_INACTIVE state is provided. The solution provides means to switch between low power receiver and normal receiver based on low power receiver signal QCLed with SSB. With this solution, the terminal stays in low power state as much as possible while keeping connectivity with the network that results in reduced battery power consumption.

A method and apparatus for positioning in a mobile communication system are provided. Method for positioning includes receiving from a base station a first type1 assistance data including a type1 identifier and one or more PRS resource set information, receiving from a base station a type2 assistance data including a validity information and a second type1 assistance data, determining based on the validity information and New Radio (NR) Cell Global identity of serving cell whether the second type1 assistance data is valid, receiving from the base station a RRCRelease including a SuspendConfig including a information indicating small data transmission is configured for Signaling Radio Bearer2 (SRB2), transmitting in RRC_INACTIVE a first message.

A method for event-based CSI reporting is provided. The method includes receiving from a base station RRCReconfiguration message that comprises various parameters for LTM such as LTM event configurations; evaluating whether LTM event is triggered; initiating LTM measurement reporting procedure if LTM event is triggered; transmitting SR based on SR configuration dedicated to LTM MR MAC CE; receiving an UL grant in response to the SR; and transmitting LTM MR MAC CE. The LTM MR MAC CE comprises a field indicating whether the LTM MR MAC CE is triggered for entering condition or leaving condition.

A method and apparatus to address the problems of supporting uplink positioning in mobile network is provided. The method of the terminal includes receiving a RRC message including configuration information for TYPE2-I-SRS, starting TYPE2-I-TAT, performing TYPE2-I-SRS transmission based on the configuration information for TYPE2-I-SRS in the first cell or in a second cell, initiating RRC resume procedure in the second cell, transmitting RRCResumeRequest in the second cell, starting T319, and determining whether to stop or continue TYPE2-I-TAT based on status of T319.

A method and apparatus for positioning in a mobile communication system are provided. Method for positioning includes receiving a first type1 assistance data, receiving a type2 assistance data, determining whether the second type1 assistance data is valid, receiving a RRCRelease, selecting a first cell, transmitting positioning SRS in RRC_INACTIVE, stopping transmission of SRS when a RRC message including a terminal identifier is received in the first cell and transmitting a specific LPP message.

A method and apparatus for positioning in a mobile communication system are provided. Method for positioning includes transmitting to a base station a UECapabilityInformation including one or more first capability information related to SRS, transmitting to a LMF a provideCapabilities including one or more second capability information related to support of SRS in RRC_INACTIVE, receiving from the base station a RRCRelease including a first information and a second information and optionally a fourth information, transmitting in a first cell based on the first information and the second information the fourth information a positioning SRS in RRC_INACTIVE and stopping in the first cell the positioning SRS if a paging message including a third information is received.

A method and apparatus to support efficient SSB transmission is provided. The method includes receiving by the terminal from the base station one or more additional ssb-periodicityServingCell, receiving by the terminal from the base station a DCI scrambled with a second RNTI, receiving by the terminal from the base station the DCI scrambled with the first RNTI and receiving by the terminal from the base station the PDSCH based on that symbols where SS/PBCH block is transmitted are not available for the PDSCH, wherein the symbols where SS/PBCH block is transmitted are determined based on the specific additional ssb-periodicityServingCell.

A method and apparatus for measurement reporting is provided. The method includes receiving from a base station a first radio resource control message, wherein the first radio resource control message comprises a set of parameters for measurement configuration, performing measurement based on the set of parameters for measurement configuration and performing for a measurement identity a set of operations in case that a report configuration associated with the measurement identity contains event trigger configuration, a specific condition is fulfilled for a set of cells, the set of cells is subset of cells of the first list and a specific indication is configured for the report configuration.
