A method and system to help provide efficient configuration of reference signal transmission in a wireless communication system. A processing system evaluates handover history between sectors in the system, considering the reference signal configurations of the sectors between which handovers have occurred, as a basis to determine what reference signal configurations to implement in one or more sectors. And the processing system may then cause the sectors to implement the determined reference signal configurations. Further, the processing system may iteratively repeat this process, to help optimize reference signal configurations throughout the region.

Configuring reference-signal transmission in a wireless communication system based on handover history

A method and system to help provide efficient configuration of reference signal transmission in a wireless communication system. A processing system evaluates the configurations of various sectors within a region, taking into account distances between the sectors and azimuths of the sectors, to determine for at least one sector an aggregate interference score with respect to one or more nearby sectors having the same reference signal as the sector. And based on the aggregate interference score, the processing system may then reconfigure reference signal transmission of the sector, such as by changing the reference signal configuration of the sector for instance. Further, the processing system may iteratively repeat this process for numerous sectors within a region, to help optimize reference signal configurations throughout the region.

When a UE is served by a first RAN and engages in signaling via the first RAN with a second RAN for the second RAN serve the UE with a call (e.g., in a circuit-switched fallback process), the second RAN will determine a speed of movement of the UE and will decide based on the speed of movement whether to provide the UE with a second-RAN traffic channel assignment in addition to providing the UE with an indication of second-RAN coverage in which the call will be served. For instance, if the UE is moving at a threshold high rate of speed, then the entity will provide the UE with a second-RAN traffic channel assignment so as to help expedite the start of the call and to help avoid an issue where the UE may move out of the second-RAN coverage in which the call is to be served.

Use of speed of movement of UE as basis to control connection setup

A method for donor selection in a relay access node includes identifying a plurality of candidate donor access nodes and obtaining one or more characteristics associated with each of the plurality of candidate donor access nodes. The method further includes determining a primary donor access node based on a comparison of the one or more characteristics between each of the plurality of candidate donor access nodes, and receiving a reference signal transmitted by the primary donor access node at a transmission power higher than a transmission power of downlink information transmitted by the primary donor access node. One or more quality characteristics of the primary donor access node are evaluated, and based on the one or more quality characteristics meeting a predetermined threshold, a connection to the primary donor access node is requested. Devices and systems relate to donor selection.

Donor selection for relay access nodes using reference signal boosting

A data communication network to provide network access data sets for User Equipment (UE) selection of a wireless relay. The wireless relays transfer relay status data to a network control system. The network control system processes the relay status data to generate network access data sets for the wireless relays and transfers the individual network access data sets for delivery to the wireless relays. The wireless relays receive their individual network access data sets and wirelessly broadcast relay Long Term Evolution (LTE) System Information Blocks (SIBs) indicating their individual network access data sets. The wireless relays receive wireless UE attachments responsive to the relay LTE SIB broadcasts of the individual network access data sets.
