Abstract:
In systems and methods of managing access node selection for a wireless device, a first handover of a wireless device from a first access node to a second access node is performed based on a traffic load of the first access node meeting a traffic load threshold, and a first signal level of the first access node and a second signal level of the second access node are monitored. During a predetermined time period, the performance of a second handover of the wireless device from the second access node to the first access node is prevented when the second signal level meets a first signal level criteria, but the second handover of the wireless device is performed from the second access node to the first access node when the second signal level meets a second signal level criteria and the first signal level meets a third signal level criteria.
Abstract:
In systems and methods for establishing communication between a wireless device and a communication network, one or more sounding signals are received from one or more relay nodes. One or more parameters of beam formation are determined based on the received one or more sounding signals. Formation of one or more beams is initiated from two or more antennas to the one or more relay nodes based on the determined one or more beam formation parameters. The total number of the formed beams and the formation of the beams are adjusted dynamically based on the received sounding signals from the relay nodes.
Abstract:
Systems and methods are described for allocating resources between frequency bands in a wireless network. A wireless device may establish multiple default channels for wireless communication with two or more cells associated with different frequency bands. The default channels on each of the cells may be used to communicate control signals between the two or more cells and the wireless device. Application requirements may be determined and each of the cells may assign a dedicated channel for service, and one of the dedicated channels may be selected to provide service to the wireless device based on the determined application requirements.
Abstract:
A communication session is established between a wireless device and a first access node, where the wireless device is located in a first coverage area of the first access node and located in a second coverage area of a second access node. A communication schedule is determined for the first access node and the second access node to communicate with the wireless device. The communication schedule can comprise a first portion and a second portion. Communication is performed between the first access node and the wireless device during the first portion, and between the second access node and the wireless device during the second portion.
Abstract:
A control element of a first wireless communication network, such as a mobility management entity, determines that a wireless device is being served by a second wireless communication network. The control element also receives an indicator associated with the availability of a base station in the first wireless communication network to serve the wireless device. Based on the indicator, the control element initiates a handover of the wireless device from the second wireless communication network to the first wireless communication network. The control element may also initiates a handover of the wireless device based on the indicator and based on a signal strength reported by the wireless device.
Abstract:
Systems and methods are described for scheduling wireless resources with coordinated multipoint transmissions. It may be determined that a signal level for a wireless device in communication with an access node does not meet a signal level criteria. Based on the determination, an access node may be instructed to transmit information to the wireless device using a coordinated multipoint transmission. A number of wireless devices in communication with the access node that comprise an application requirement that meets an application requirement criteria may further be determined. Then, the access node may be instructed to schedule wireless transmissions using at least one of semi-persistent scheduling and delay based scheduling based on the determined number of the plurality of wireless devices and the instruction to transmit using the coordinated multipoint transmission.
Abstract:
Synchronization information and access node identification information are transmitted from a first access node and a second access node. It is determined that loading information of the first access node meets a first loading criteria and loading information of the second access node meets a second loading criteria. A message is transmitted from the first access node comprising the determination that the loading information of the first access node meets the first loading criteria and the loading information of the second access node meets the second loading criteria. The wireless device then determines the second access node identification based on the message and on the synchronization information. An access request is received at the second access node to initiate a communication session between a wireless device and the second access node.
