  • Link switch in a wireless communication system
    Patent number: 10880793
    Abstract: A wireless communication device (16) is configured for use in a wireless communication system. The device (16) in this regard is configured to receive a command (22) that commands the device (16) to perform a link switch (24) from a source link (20A) to a target link (20B) responsive to fulfillment of a condition. The command (22) may indicate a target link configuration (26) relative to a source link configuration. The device (16) is also configured to store information (30) from which the target link configuration (26) indicated by the command (22) is determinable irrespective of any change to the source link configuration occurring after receipt of the command (22). In some embodiments, the device (16) is configured to, responsive to fulfillment of the condition, perform a link switch (24) from the source link (20A) to the target link (20B) using the target link configuration (26) as determined from the stored information (30).

  • Minimizing network planning using reference signal grouping
    Patent number: 10784941
    Abstract: According to some embodiments, a method for use in a network node of transmitting reference signals in a wireless network using a plurality of beams comprises obtaining a node identifier for the network node. The node identifier is unique for neighboring network nodes within a particular coverage area of the wireless network. The method further comprises obtaining a group of reference signal sequences. The group comprises a subset of a pool of possible reference signal sequences for use in the wireless network. Each reference signal sequence is associated with a beam reference identifier. The method further comprises selecting a reference signal sequence from the obtained group: scrambling a reference signal transmission pattern using the obtained node identifier and the selected reference signal sequence with associated beam reference identifier; and transmitting the scrambled reference signal transmission pattern to a user equipment on one of the beams among the plurality of beams.

  • Synchronization signal search
    Patent number: 10645662
    Abstract: A wireless communication device in a cellular wireless communication system activates (402) radio receiver circuitry during repeated time windows. The repeated activation has a nominal repetition time interval, T, and each repeated time window has a window duration, DT. During each DT, detection (404) is made of a plurality of synchronization signals that are transmitted by a respective cell. Based on the detected synchronization signals, calculation (406) is made of a respective cell quality value. These calculated quality values are then provided (408) to a mobility process. Depending (410) on the calculated quality values and at least a first quality threshold, any of T and DT are adjusted (412).

  • OPTIMIZATION OF LOGICAL CHANNEL PROCESSING FOR MULTIPLE TRANSPORT BLOCKS
    Publication number: 20200084662
    Abstract: Some embodiments of this disclosure provide a method for optimizing the processing of logical channels when multiple transport formats are to be served. In certain aspects, instead of filling sequentially each transport format one by one, the protocol packets to be transmitted by the transport block are concurrently constructed. This may be accomplished, for instance, by taking into consideration the requirements of the data (for example, latency and reliability) to be transmitted as well as the characteristics of the available transport format (for example, size, expected channel quality, transmission length, etc.).

    Patent number: 10560949
    Abstract: A second communication device transmits information relating to a request for a first set of radio resources of a radio channel for a first data transmission to a third communication device. This information is received by a first communication device. In response thereto, the first communication device transmits an interference notification to the second communication device when the received information relating to a request for radio resources of the radio channel is determined to conflict with requested radio resources of the radio channel for a second data transmission to or from the first communication device. The second communication device receives an interference notification from the first communication device indicating that its transmitted information relating to a request for radio resources of the radio channel has been determined to conflict with requested radio resources of the radio channel for the second data transmission to or from the first communication device.

  • Beam Selection for Wireless Devices in a Wireless Communications Network
    Publication number: 20190342872
    Abstract: Embodiments herein relate to a method performed by a radio network node (12) for facilitating beam selection for wireless devices in a wireless communications network. The radio network node obtains a first parameter indicating a mapping between an uplink signal, US, sequence and a beam-formed reference signal, RS, which mapping is for two or more wireless devices that are configured to perform measurements on beam-formed reference signals and to use US sequences to report selected beams, and a second parameter distinguishing the US sequence being reported from one wireless device from the US sequence being reported from one or more other wireless devices. The radio network node further receives an indication of the US sequence transmitted from one of the two or more wireless devices (10); and identifies the beam for the wireless device based on the received indication and the first and second parameters.

  • Link Switch in a Wireless Communication System
    Publication number: 20190261238
    Abstract: A wireless device in a wireless communication system is configured to perform measurements on a set of candidate links for supporting a network node in the system to make a decision as to which of the candidate links is to be a target link for a link switch. The wireless device reports (e.g., at the physical layer) measured candidate links one link subset at a time in order of the wireless device's preference for the target link, until the wireless device receives a target indication signal indicating which of the candidate links in the set is to be the target link. Any given link subset reports one or more candidate links which the wireless device has measured for the decision. Responsive to receiving the target indication signal, the wireless device performs the link switch to the indicated target link.

  • DATA TRANSMISSION DURING HANDOVER
    Publication number: 20190239129
    Abstract: The present invention relates to handling data transfer during handover, whereby a terminal device is initially connected to a serving access node and a handover is performed to connect the terminal device to a target access node. The improved handling of data transfer is achieved by upon making a handover decision, performing data rerouting to the target access node while continuing to exchange data between the terminal device and the serving access node, and stopping the data exchange between the terminal device and the serving access node in response to an indicator indicating that the target access node is ready to proceed with the handover.
