  • NEIGHBOR RELATION ESTABLISHMENT IN WIRELESS COMMUNICATIONS NETWORKS
    Publication number: 20180288675
    Abstract: According to an aspect, a wireless device receives, from a first node, a blacklist with random access response identifiers. The wireless device transmits a random access preamble to initiate random access to another node and receives a random access response. The wireless device compares a random access response identifier included in the received random access response to the random access response identifiers in the blacklist and establishes a connection to a second node that corresponds to the received random access response, responsive to determining that the random access response identifier in the received random access response is not included in the blacklist. The wireless device sends, to the second node, an identifier for the first node or an identifier for a beam transmitted by the first node, or both.

  • NETWORK NODE AND METHOD FOR AVOIDING DROP OF A CONNECTION DUE TO RTP TIMEOUT
    Publication number: 20180279402
    Abstract: A method performed by a network node for preventing a release of a connection from a User Equipment (UE) to the network node, which connection uses a Real Time Protocol (RTP) for media transfer. The network node operates in a wireless communication network and serves the UE. The network node detects a gap in a packet flow of the connection. When the network node has detected the gap in the packet flow, the network node prevents the UE from initiating a release of the connection caused by the gap in the packet flow, by sending a message to the UE, which message forces the UE into a failure. The failure triggers the UE to initiate a Radio Resource Control (RRC) Connection Reestablishment procedure.

  • Method and apparatus for controlling cell aggregation
    Patent number: 9973959
    Abstract: According to one aspect of the teachings herein, a wireless device operating in a wireless communication network determines the difference in signal arrival times with respect to first and second cells, and the device and/or the involved wireless communication network uses the difference to control one or more aspects of Carrier Aggregation, CA, operation for the wireless device. For example, there may be a maximum timing difference defined for the wireless device, e.g., as a function of its inherent capabilities, and the wireless device may evaluate the timing difference of a second cell that is a candidate of aggregation into its CA configuration, or that may be a candidate for activation as a serving cell within a CA configuration, with respect to a first cell that is already in use as a serving cell for the wireless device.
