Abstract: Disclosed are methods and systems for a wireless communication network including detecting a trigger to switch a serving channel at a first access point, and communicating a first channel switch message from the first access point to a second access point. The first access point may be in a downstream and/or upstream or communication flow in relation to the second access point. The process may include communicating a first Channel Switching Announcement (CSA) message from the second access point to at least one client of the second access point, where the least one client is one of a plurality of clients receiving internet connectivity through a series of communication flows including a data flow through the second access point. The process further includes revising a time to switch channel information included in the first channel switch message, where the first CSA message includes the revised time to switch channel information.

Abstract: The disclosure relates in some aspects to location reporting and paging for satellite communication. In one aspect, the disclosure relates to a user terminal (UT) sending a message to report information about the UT's location. A threshold may be used to control whether (e.g., when) the UT reports its location. The location information may be used to enforce area (e.g., country) restrictions for the UT. In one aspect, the disclosure relates to forwarding paging messages between network access controllers. For example, a network access controller that is not able to page a UT may forward a paging message to another network access controller. In one aspect, the disclosure relates to a list of paging areas that indicates where a UT need not perform a paging area update.

Abstract: Methods, systems, and devices are described for wireless communication at a device. A transmitting device such as a base station may select some packets for direct transmission to a receiving device using data compression based on the reliability of the direct connection. The transmitting device may select other packets for indirect transmission via an unreliable connection using uncompressed packets or compressed packets that will not be used to update a compression buffer. In some cases, uncompressed packets may also be sent via the reliable connection. If a packet sent over the unreliable connection is lost, it may be transmitted over the reliable connection.

Abstract: Apparatus and methods of controlling call establishment are described. A user equipment (UE) may determine to establish a call. In an aspect, the UE may detect a Wireless Local Area Network (WLAN) access node and receive, from a Wireless Wide Area Network (WWAN) access node, WWAN load-related information.

In another aspect, the UE may determine WLAN access node characteristics associated with a received signal from a WLAN access node. The UE may forward a call establishment request, including the WLAN access node characteristics to a WWAN access node. The UE may receive a redirection command to redirect the call establishment request to the WLAN access node.

Abstract: The described aspects include a user equipment (UE) apparatus, network apparatus, and corresponding methods of using fallback resources for communication. The UE can indicate fallback information to a network apparatus specifying whether fallback resources are preferred for communicating uplink data and can receive a fallback decision from the network apparatus specifying whether fallback resources are to be used for communicating the uplink data. The UE can then determine whether to communicate the uplink data to the network apparatus based in part on the fallback decision. The network apparatus can receive a preamble from a UE related to requesting access for transmitting uplink data and can determine a fallback decision specifying whether the UE is to utilize fallback resources in communicating the uplink data. The network apparatus then communicates the fallback decision to the UE.

Abstract: The present disclosure provides methods and apparatuses for improved Iub link congestion management based on a dynamic scaling of flow control request message transmission in multiflow wireless environments. For example, in an aspect, methods and apparatuses are provided for receiving, at a NodeB, a data request from one or more user equipment (UE), wherein each data request corresponds to a flow and the one or more UE is served by a plurality of NodeBs, generating a flow control request corresponding to each flow in response to each data request, and sending each flow control request to a radio network controller (RNC). Thereafter, a Node B may receive data in response to each flow control request, determine a congestion state based on a downlink delay from the RNC detected in the received data, and scale a subsequent one or more flow control requests based on the determined congestion state.

Abstract: In aspects of the present disclosure, a user equipment receives inter-NodeB multi-point transmissions, and a multipoint aggregation component detects a gap in the sequence numbers, delays transmitting a not acknowledged signal (NAK) by starting a NAK delay timer, and transmits, by a transceiver, NAK for the gap in sequence numbers in response to the NAK delay timer expiring and detecting that the gap has not been filled during the delaying. If the Medium Access Control (MAC) entity as the respective NodeB identifies itself to the Radio Link Control (RLC), out-of-order delivery (skew) can eventually be distinguished from genuine data loss before the NAK delay timer expires based upon tracking the highest sequence numbers received. Adaptive NAK delay timer can be performed by monitoring skew duration.

Abstract: Methods and apparatuses are provided for access control in a wireless communication system. In particular, certain parameters utilized by access terminals (336) for a random access procedure may be partitioned, such that different classes of access terminals may be controlled independent of other classes. Here, an exclusive set of access classes may be utilized by low-priority machine type communication devices, such that the broadcasting of a bit mask corresponding to the access classes can bar some or all of the low-priority devices. Further, a new access service (904) class may be utilized exclusively by the low-priority devices, wherein the signature space utilized for random access attempts can be partitioned between the new access service class (904) and all other access service classes (902).
