Abstract: Embodiments disclosed herein may be implemented by a first access node in an access network, such as by an eNodeB in an LTE network, in order to determine an uplink coordinated multipoint (CoMP) mode for one or more other access nodes with which the given access node is coordinating. An example method involves: (a) determining, by a first access node, a central processing unit (CPU) load of a second access node, (b) based at least in part on the CPU load of the second access node, the first access node selecting a coordinated multipoint (CoMP) mode from a plurality of CoMP modes, and (c) sending a CoMP-mode message from the first access node, wherein the CoMP-mode message instructs the second access node to use the selected CoMP mode.

Abstract: A method and system for pre-configuring a UE with timing advance for use in communication with a handover target. When a UE is being served by a source base station, the source base station transmits to a target base station a measurement request that specifies an uplink reference signal that the UE will provide, and the target base station evaluates that uplink reference signal to determine a timing advance for the UE and reports the timing advance in a response to the source base station. As the source base station then directs the UE to hand over to the target base station, the source base station then provides the UE with an indication of the timing advance provided by the target base station. The UE may then transition to be served by the target base station and to make use of the indicated timing advance.

Abstract: A radio access network (RAN) may be configured to manage paging of a wireless communication device (WCD). The RAN may initiate a paging process to page the WCD, and the paging process may comprise the RAN transmitting to the WCD a defined sequence of page attempts until the RAN receives a page response from the WCD or the RAN has transmitted a final page attempt of the sequence. After the RAN has transmitted at least one page attempt of the sequence but before the final page attempt of the sequence has been transmitted, the RAN may determine that the RAN has not received the page response from the WCD, and that the WCD is currently engaged in active data communication, and the RAN may responsively discontinue the paging process.

Abstract: A method and apparatus for managing page-response intervals. When a network entity receives a paging trigger signal, the entity determines a page-response interval to use for paging the mobile station, based on one or more factors such as (i) whether the communication is to be provided to the mobile station over the same air interface and/or same air interface protocol that will carry the paging to the mobile station and/or (ii) what network, interface, or other entity the trigger signal comes from and/or what network communication module receives the trigger signal. The network entity then uses the determined page-response interval when paging the mobile station, waiting that determined period of time after each page attempt before attempting to page again or before concluding that the paging effort failed.

Abstract: Disclosed herein are systems and methods for symmetrical implementation of inter-cell interference coordination (ICIC) in a radio access network (RAN) having a first base station serving a first set of access terminals and a second base station serving a second set of access terminals. In an embodiment, a network entity makes both a first determination that each access terminal in the first set is receiving at least a threshold-strong signal from the second base station and a second determination that each access terminal in the second set is receiving at least a threshold-strong signal from the first base station. Responsive to making these determinations in combination, the network entity manages an assignment of reverse-link resource blocks in the RAN such that no reverse-link resource blocks are assigned to both an access terminal in the first set and an access terminal in the second set.
