Abstract: In order to perform a RACH-less handover from a source base station to a target base station, a UE device generates a request that the target base station is to send a Media Access Control (MAC) message to the UE device. The request can be sent with a Radio Resource Control (RRC) Connection Reconfiguration Complete message. Alternatively, an RRC message sent from a UE device functions as an implicit request that the target base station is to send a MAC message to the UE device. The request can also be configured to specify a particular MAC Control Element that the target base station should send. The target base station transmits the requested MAC message, along with TA information, if required. The UE device determines when the handover has been completed, based at least partially on when the requested MAC message is received from the target base station.

Abstract: Uplink signals transmitted from each of a plurality of UE devices being served by a serving eNB are received at a neighbor cell eNB. Information regarding the uplink signals received by the neighbor cell eNB is then sent to the serving eNB. The UE devices are identified based on the information. An aggregate load level of the UE devices is determined based on resource load requirements of each UE device. In some instances, it is determined which of a plurality of deactivated neighbor cells should be activated based on load levels associated with one or more UE devices that are determined to be near each of the plurality of deactivated neighbor cells.

Abstract: A cellular communication system and method for delivering information, e.g., data and/or control-signaling, to a user equipment (UE) from a neighboring node are disclosed. The cellular communication system includes a first node configured to transmit information in one or more Multicast Broadcast Single Frequency Network (MBSFN) subframes over a radio frequency (RF) link between the first node and the UE, while the UE is being served by a second node. The first node can use a network-defined, dedicated portion of the MBSFN subframe for this purpose. Instead of only allowing the second node to send data/signaling messages to the UE, the disclosed techniques allow neighboring nodes to also deliver information to the UE. In particular, the neighboring nodes can transmit data and/or control-signaling to the UE using MBSFN subframes in order to minimize signaling overhead and signaling delay.

Abstract: A user equipment (UE) device determines to switch core network access from a cellular radio access network (RAN) to a wireless local area network (WLAN) RAN for data traffic associated with a packet data network (PDN) at least partially based on a comparison between QoS information of the PDN received from the core network and UE data throughout estimate
