Systems and methods for improved communication efficiency in high efficiency wireless networks

Systems, methods, and devices for priority based management of the connections between a device and a network are described herein. In some aspects, a device may include multiple applications with different access priorities. As a result of a mobility event, such as change in location or resuming operation after an idle period, the device may be configured to transmit a signal indicating its status. The signal may include an access priority value. Various methods and systems for determining an access priority value for devices configured to support one or more access priorities are described.

Systems and methods for priority based session and mobility management

An apparatus and method for allocating a data flow based on selection criteria including receiving at least one policy including at least one indication for selecting an access from two or more of available accesses; determining a selection criterion based on the data flow; and selecting the access based on the determined selection criterion and the at least one indication. In one example, the selection criterion is one of the following: a bandwidth requirement for the data flow, an application generating the data flow, a protocol used to carry the data flow, a file size, an application name/ID, a role ID, or a throughput of the data flow. In one example, the policy is a management object (MO) received from an Access Network Discovery and Selection Function (ANDSF) module and the selected access is for a wireless local area network (WLAN), a LTE network or for a 3GPP service.

Apparatus and method for allocating data flows based on indication of selection criteria

The present disclosure presents a method and apparatus for identifying an access point (AP) for selection by an access terminal (AT). For example, the method may include receiving a probe request by one or more APs from an AT, wherein the probe request is broadcasted by the AT to the one or more APs, generating load information and Received Signal Strength Indicator (RSSI) values of the probe request at the one or more APs, identifying an AP of the one or more APs for selection by the AT, wherein the AP for selection by the AT is identified by the one or more APs based at least on the load information and RSSI values generated at the one or more APs, and transmitting information of an AP identified by the one or more APs to the AT. As such, an improved mechanism for selecting an access point may be achieved.

Additionally, the methods and apparatus include selecting the first potential channel from a channel list when the first timer value meets or exceeds the first timer threshold value. In another aspect, methods and apparatus include detecting an initial channel selection condition for triggering selection of a first initial channel. The methods and apparatus further include forming a channel list including one or more channels based on one or more channel selection parameters. Additionally, the methods and apparatus include selecting the first initial channel from the channel list.

Methods and apparatus for channel selection in a wireless local area network

A coax line terminal (CLT) transmits allocations of upstream bandwidth to a plurality of coax network units (CNUs). In response to the allocations, the CLT receives frames with data in a plurality of physical resource blocks that each correspond to a distinct set of subcarriers. The plurality of physical resource blocks includes a first group of physical resource blocks that all have a first constant allowed capacity. Sizes and modulation orders of respective physical resource blocks in the first group vary as defined by a first modulation profile. The data in the first group are received from one or more CNUs that are assigned the first modulation profile.

Constant-capacity physical resource blocks for upstream transmissions over coax

A communication device includes a resource allocation module to allocate coax resources for signals to be transmitted over a cable plant and a coax physical layer device to transmit the signals over the cable plant using the allocated coax resources. The communication device also includes a media access controller, coupled to the multi-point control protocol implementation and the coax physical layer device, to provide to the coax physical layer device a bitstream that includes data for the signals and also includes information specifying the allocated coax resources.

Methods and systems of specifying coaxial resource allocation across a MAC/PHY interface

A network device includes a plurality of physical-media entities (PMEs), each corresponding to a distinct channel, to generate transmit signals based on transmit packets received over a media-independent interface. The network device also includes a channel-bonding sublayer to direct the transmit packets from the media-independent interface to respective PMEs of the plurality of PMEs. The channel-bonding sublayer has a substantially fixed delay between the media-independent interface and the plurality of PMEs for the transmit packets.

Physical-layer channel bonding

In a method of scheduling frames, a first channel of a plurality of channels is selected for a first frame. The first frame is sent across a media-independent interface to a physical-layer device for transmission on the first channel. A data rate of the media-independent interface is greater than a data rate of the physical-layer device for the first channel. After the first frame is sent across the media-independent interface, subsequent sending of frames for the first channel across the media-independent interface is disabled for a period of time that is based at least in part on rate adaption from the data rate of the media-independent interface to the data rate of the physical-layer device for the first channel.

Methods and apparatuses are provided that facilitate detaching one of a plurality of network connections to ensure state information is retained at one or more network nodes. For a device initiated detach, the device can transmit a handover message related to performing a handover of one network connection to another active network connection, as opposed to explicitly detaching the network connection. This can cause at least some state information, such as a gateway identifier, to be retained in one or more network nodes. For a network initiated detach, a gateway can provision state information to a state information server following receiving a routing tunnel termination message to ensure state information deleted as a part of the detach is re-provisioned to the state information server.

Techniques are provided for efficient detachment from or attachment to wireless network(s). In one example, there is provided a method, operable by the user equipment (UE), that may involve connecting to a first wireless network (e.g., a 3GPP network) associated with a first access point name (APN), and connecting to a second wireless network (e.g., a WAN) associated with a second APN. The method may involve performing handover for the first APN from the first wireless network to the second wireless network. The method may involve performing detach for the first APN from the second wireless network.
