Abstract: Systems and techniques for handover management between macro base stations and home base stations. Upon receiving a measurement report from a user device including a physical cell identity and frequency pair associated with a candidate handover home base station, a macro base station transmits a message to a home base station gateway to obtain cell global identifiers of specified home base stations, which may include home base stations associated with a list of physical cell identifiers and frequency pairs including the pair received in the measurement report. Upon receiving the cell global identifiers, the base station identifies a handover target and performs signaling to the user device to direct handover to the target.

Abstract: Delivery of protocol data units or other suitable data or information units in various communication systems can be enhanced by appropriate methods and devices. For example, in-sequence delivery of protocol data units received in parallel from several lower-layer acknowledged-mode protocol entities may benefit from timers and/or forwarding status reports. A method can include observing a gap in a sequence of protocol data units received from a plurality of lower-layer protocol entities providing data transfer. The method can also include starting a timer upon the gap observation. The method can further include preventing the gap from blocking delivery of service data units to a higher layer, when the timer expires. The method can additionally include detecting a forwarding-status report. The method can also include immediately proceeding with data delivery to higher layer, containing the gaps because of the lack of forwarding at handover.

Abstract: Indication of delivery-path information may benefit various communication systems. For example, wireless communication systems may benefit from per-protocol data unit delivery-path indication to data recipient or from setting a timer expiry value dependent on such received information. A method can comprise sending, by a data-sending protocol entity, a control protocol data unit. The control protocol data unit can identify protocol data units destined to a data-receiving protocol entity. The method can also comprise providing in the control protocol data unit, for each of the identified protocol data units, a direct or indirect indication of at least one delay figure of a delivery path chosen for an initial transmission of the identified protocol data unit.

Abstract: Systems and techniques for handover management between adjacent cells. A base station, such as a macro base station serving a macro cell identifies a user device as a candidate for handover based on specified criteria and communicates a handover request to a femto base station. The femto base station evaluates specified conditions, such as energy efficiency, for the cell it is serving and allows the handover only if the handover would improve the conditions.

Abstract: Certain networks can operate using circuit switched infrastructure, while other networks may operate using infrastructure for the long term evolution (LTE) of the third generation partnership project (3GPP). Devices can operate across the boundaries of these networks. Thus, such devices as well as the networks may benefit from network sharing in reverse single radio voice call continuity. For example, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include providing a network identification corresponding to the source network while requesting the handover. Alternatively, or in addition, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include determining the target network based on a network identification received previously.

Abstract: An allocation of downlink resources is received, which are monitored on l layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate l reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data.

Abstract: A persistent or a semi-persistent uplink resource allocation also comprises an indication for a user equipment UE to send channel quality reports. The format for the channel quality report is determined (based on a transmission mode for which the UE receives a downlink shared channel). In at least first transmissions of user data for instances of the persistently allocated uplink resource the UE sends user data and a channel quality report according to the determined format. For the case that a NACK is received in reply to one of those sent user data with channel quality reports, four options are detailed: re-send the NACK'd user data on a next instance of the persistently allocated UL resource with or without a channel quality report, and re-send the NACK'd user data on a dynamically allocated uplink resource with or without a channel quality report.
