  • Publication number: 20220182920
    Abstract: A wireless device 10,120 and a method performed therein for receiving scheduled positioning system information from a radio network node 20, 110. The wireless device and the radio network node operate in a wireless communications network 100. The wireless device receives, from the radio network node, positioning system information scheduling information (pSI) and at least one out of a scheduling offset and a number of system information messages with positioning system information blocks (pSIMs) per system information (SI) window. Further, the wireless device determines in which subframes one or more pSIMs are scheduled by the radio network node based on the pSI and based on at least one out of the scheduling offset and the number of pSIMs per SI window. Furthermore, the wireless device uses the determined scheduling of the one or more pSIMs for receiving the one or more pSIMs.

  • Publication number: 20210377316
    Abstract: A method is provided to operate a CN node to determine UP security activation. A UP session establishment request is obtained for a wireless device. An indication is obtained that the UP session establishment request is associated with an emergency session and/or that null ciphering and/or null integrity protection are applied to a CP associated with a CP session for the wireless device. It is determined that a UP should be configured for the UP session without activating integrity and/or confidentiality protection for the UP based on the indication. A UP security policy is provided to a RAN node associated with the wireless device, wherein the UP security policy indicates to configure the UP for the UP session without activating integrity and/or confidentiality protection based on determining that a UP should be configured for the UP session without activating integrity and/or confidentiality protection.

  • Publication number: 20210360513
    Abstract: A UE transmits a radio access capability to a base station. The radio access capability is transmitted via an information element that comprises a bitmap in which a bit has a value that indicates, to the base station, support of a modification to at least one of a maximum power reduction or a spectrum emission requirement. According to embodiments, the base station manages the UE based on the supported modification. Such managing of the UE may include, for example, one or more of admission control, imposing scheduling restrictions, and imposing handover restrictions.

  • Publication number: 20210092690
    Abstract: A wireless device that indicates multiple power classes to a network node, a network node that uses the indicated multiple power classes, and related methods of operation for the wireless device and the network node are disclosed. The disclosed embodiments aim at an increase flexibility in setting different power classes in different communication scenarios while reducing signalling overhead for capability signalling for the wireless device. This is achieved by using at least one set of power classes defining at least two power classes of the wireless device. Each set of power classes applies to a transmission band (A, B, C) supported by the wireless device and each power class in each set of power classes applies to a specific operative condition of the wireless device.

  • Publication number: 20210092787
    Abstract: In one aspect, a wireless device (50) configured for multi-carrier operation in a wireless communication network performs (702) measurements on one or more cells and/or beams and/or carriers, while in idle mode or in an inactive state. The wireless device determines (704) information for assisting an establishment of multi-carrier operation, based on the measurements, and transmits (706) the information to the wireless communication network. A network node receives this information for the cells/PERFORM beams/carriers and selects, based on the received information, one or more cells/beams/carriers for multi-carrier operation with the wireless device. The network node establishes multi-carrier operation for the wireless device using the selected cells/beams/or carriers.

  • Patent number: 10715286
    Abstract: An inventive UE carrier aggregation (CA) capability reporting signalling model allows UEs (30) aggregating large numbers of component carriers to transmit CA-relevant capabilities to the network more efficiently than the current (legacy) signalling model. Rather than reporting CA/MIMO/CSI/NAICS capabilities separately for each supported band combination, including fallback configurations, embodiments of the present invention either report UE Radio Frequency (RF) and Baseband (BB) related capabilities separately, or report them disassociated from CA band configurations. This approach avoids the need to signal the full UE (30) set of capabilities for each of (possibly many) supported band combinations. Furthermore, fallback capabilities are signalled implicitly, eliminating the need to transmit this data.

  • Publication number: 20200221290
    Abstract: According to some embodiments, a method of signaling device capabilities for use in a wireless device comprises compiling frequency band combinations supported by the wireless device. The method further comprises compiling a set of device capabilities supported by the wireless device and assembling a capability message. The capability message includes: the frequency band combinations; combinations of the device capabilities supported by the wireless device; and for each of the one or more frequency band combinations, the capability message includes a first indication of one or more device capabilities supported by the frequency band combination. The first indication of the device capabilities supported by the frequency band combination comprises, for each band of the plurality of frequency bands, an indication of one of the one or more combinations of the device capabilities supported by the band when used in combination with the other bands in the frequency band combination.

  • Publication number: 20200120578
    Abstract: A wireless device (120) and a method therein for receiving positioning assistance data from a network node (110). The device receives information about radio resources that are to provide scheduling information of a positioning System Information Broadcast (SIB) which scheduling information is different from scheduling information of non-positioning SIB. The device uses the radio resources for receiving scheduling information of the positioning SIB. Further, the device receives positioning SIBs comprising positioning assistance data. The device determines whether or not the positioning assistance data of the received positioning SIBs is same in a second cell and a first cell.
