  • Patent number: 9049627
    Abstract: Some embodiments provide a mobile relay node, RN, (16) with complete and valid neighbor cell information. The RN (16) requests this information from a donor base station (12) upon detecting a defined condition characteristically indicating that movement of the RN (16) has rendered previously obtained neighbor cell information incomplete or invalid. The RN (16) may generate the request to identify cells (18) currently neighboring the mobile cell (20). The donor base station (12) may then provide the RN (16) information that more specifically pertains to the mobile cell's neighbors, rather than generally pertaining to the donor cell's neighbors. Other embodiments compensate for the RN's incomplete or invalid neighbor cell information. These embodiments permit the RN (16) to identify a target cell (18) with a non-unique cell identifier in a handover message sent to the donor base station (12).

  • Patent number: 8995282
    Abstract: A method and arrangement for estimating the current channel quality for a data transfer in a mobile network. In a sending system entity, a channel quality estimate (CQE) associated with a data transfer to a receiving system entity in a mobile communication network is adjusted. One or more probing packets are communicated 400 between the sending system entity and the receiving system entity, each probing packet being formatted according to a predefined combination of transmission parameters. Furthermore, is a Channel State Information (CSI) report received 404 from the receiving system entity, and the CQE is adjusted 406 based on the CSI report and which probing packets have been successfully communicated. By sending a sequence of probing packets, each formatted according to a predefined combination of transmission parameters, and not waiting for each packet to be acknowledged, a fast and accurate estimation of the current channel quality is achieved.

  • Publication number: 20150063278
    Abstract: A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.

  • Patent number: 8886114
    Abstract: Teachings herein include a base station and a relay node for propagating system information changes from the base station to the relay node. Upon receiving changes from the base station, the relay node advantageously determines whether to apply the changes immediately or to defer application until a set time period. The relay node then applies the changes at a time in accordance with that determination. In some embodiments, the relay node employs deferred application for fundamental changes (those changes that would fatally disrupt ongoing communications if applied before the set time period), but employs immediate application for non-fundamental changes in order to minimize relay node complexity. Regardless, the relay node may make the determination based on preconfigured rules, or on control indicators received from the base station. Correspondingly, the base station may generate the control indicators to explicitly direct the relay node to employ immediate application or deferred application.

  • Publication number: 20140198701
    Abstract: A method in a user equipment for deciding whether or not to send an uplink transmission (ie. Channel State Information, CSI, and/or Sounding Reference Signal, SRS) to a radio access network node (Node B) is provided. The user equipment and radio access network node (Node B) are comprised in a communications network. The user equipment is configured with Discontinuous Reception, DRX, to be in active time or not be in active time. The user equipment decides (201) whether or not to send the uplink transmission at a transmission time t, based on whether the user equipment was in active time or not at a predefined earlier time instance relative to the transmission time t.

  • Patent number: 8780783
    Abstract: Teachings herein include a base station for propagating system information changes from the base station to the relay node. Upon transmitting system information changes to the relay node, the base station defers data transmission between the base station and the relay node until a set time period. In many embodiments, the base station is configured to actually apply the system information changes during this time period, while the relay node applies the changes before then, e.g., by applying them immediately upon reception. The base station's deferral of data transmission until the set time period thus ensures that data transmission does not occur until both the base station and the relay node have applied the pending changes. This in turn prevents radio link failure from occurring due to use of different system parameters by the base station and relay node.
