  • Publication number: 20240107559
    Abstract: A communications network can include a communication device and a network node. The communication device can receive a notification message from the network node. The communication device can determine whether the network node will transmit control information that is associated with the communication device via a multicast control channel (“MCCH”) based on the notification message. Responsive to determining that the network node will transmit the control information, the communication device can determine a time offset indicating an amount of time that will be between the notification message and the control information. Responsive to determining the time offset, the communication device can determine whether to enter a lower power state based on the time offset.

  • Publication number: 20230370893
    Abstract: Embodiments herein relate to a method performed by a network node in a telecommunication network providing a multicast transmission to a group of devices residing in a cell of the telecommunication network. The network node monitors a congestion level for communication, and, if the congestion level reaches a first threshold, the network node orders for at least one device in a RRC connected mode to be released from the RRC connected mode to an RRC idle mode or an RRC inactive mode, thereby disabling a capability of the at least one device to provide one or more re-transmission requests while keeping an ability of the at least one device to further receive the multicast transmission.

  • Patent number: 11496992
    Abstract: Methods and device for use in a wireless device of reporting positioning measurements comprises receiving network assistance information from a network node. The network assistance information is for assisting the wireless device in performing Observed Time Difference Of Arrival (OTDOA), and comprises: a list of reference cells; a list of neighbor cells; and a rule for terminating Reference Signal Time Difference (RSTD) measurements. The method further comprises performing RSTD measurement between a cell in the reference cell list and a cell in the neighbor cell list. Upon determining the RSTD measurement satisfies the rule for terminating RSTD measurements, the method includes reporting the RSTD measurements to the network node. Upon determining the RSTD measurement does not satisfy the rule for terminating RSTD measurements, performing another RSTD measurement between the cell in the reference cell list and a cell in the neighbor cell list.

  • Publication number: 20220217564
    Abstract: Systems and methods for relaxed inter-frequency measurements are provided. In some embodiments, a method performed by a wireless device for relaxing inter-frequency measurements includes receiving an indication that frequencies should have relaxed inter-frequency measurements; and relaxing the inter-frequency measurements for the indicated frequencies. In this way, in some embodiments, the wireless device relaxes measurements on that frequency only when the network indicates that relaxed measurements may be applied to the inter-frequency. This implies that legacy measurement performance and mobility is retained. The measurements can be relaxed when the network is aware of spotty coverage on certain frequencies. Furthermore, the network has explicit control over the relaxation, e.g., the network can indicate how much the measurements may be relaxed, i.e., there can be a guarantee for a minimum measurement performance.

  • Publication number: 20220191788
    Abstract: Systems and methods related to permissible transmission gap assistance information provided by a wireless device (e.g., a User Equipment (UE)) to a base station in a cellular communications network are disclosed. In one embodiment, a method performed by a wireless device for a cellular communications network comprises determining a transmission gap for the wireless device. The transmission gap is a time gap during which no uplink or downlink data transmission is anticipated or required by the wireless device. The method further comprises transmitting information comprising an indication of the transmission gap to a network node. In this manner, information is provided to the network node that enables scheduling uplink and downlink data transmissions to the wireless device during the transmission gap, thereby enabling the wireless device to reduce power consumption by, e.g., entering a sleep state during the transmission gap.

  • Patent number: 11356955
    Abstract: There is provided a method in a wireless terminal device for a wireless communications network. The wireless terminal device is operable in a mode in which the wireless terminal device is configurable to wake at defined instances to monitor a control channel for control messages from the wireless communications network. The control messages indicate radio resources for a shared channel over which one or more further messages are to be transmitted. The method comprises, while operating in the mode, monitoring for receipt of an indication from a network node operable in the wireless communications network in a time window associated with a particular defined instance. The indication indicates that data is available at the wireless communications network for transmission to the wireless terminal device.

  • Publication number: 20220132417
    Abstract: Techniques are described for providing assistance information to the network that is useful in determining when to change an operating mode of the UE to reduce the power consumption of the UE. The assistance information may be used, for example, to release the UE from a RRC_Connected state; release one or more component carriers (e.g., SCells) in a set of aggregated carriers that are not being used, signaling the UE to go to sleep during an ON duration while an inactivity timer associated with a DRX configuration is running.
