    Abstract: A method, computer readable media and a system for determining a Voice over LTE (VoLTE) codec is presented. In one embodiment a method includes discovering a packet header size used in a session using a Silence Insertion Descriptor (SID); inspecting downlink packet sizes coming into a receive buffer; determining when three consecutive packet sizes are greater than zero, then setting a first factor, a second factor, and a third factor equal to zero; calculating a header size; and determining a voice encoding codec by subtracting a header overhead value from the packet size.

    Abstract: This invention relates to an efficient and simple best effort UL FFR, describing how to effectively partition the bandwidth (BW) into regions and how to allocate different UEs into those partitions. In one embodiment, a method of Uplink (UL) Fractional Frequency Reuse (FFR) includes classifying a User Equipment (UE) as either a cell-edge UE or a cell-center UE; examining each UE before each UL scheduling and updating a status of the UE that was examiner; and choosing a cell-edge segment for each cell, a cell-edge segment including a starting SB index and an end SB index, wherein an SB is a group of Resource Blocks (RBs), wherein the cell edge segment is defined using the physical cell indicator (PCI) as an input.

    Abstract: A method and system for for providing Circuit Switch Fall Back (CSFB) with Radio Access Network (RAN) Information Management (RIM) without network support is presented. In one embodiment, a method includes receiving, by a coordinating server, direct information transfer System Information (SI) messages with RIM Packet Data Unit (PDU) from an eNodeB; sending, by the coordinating server, a RAN-information-request message to a relevant cell, using the routing information in the RIM PDU; collecting and replaying by the cell the SI needed for CFSB to the coordinating server; storing, by the coordinating server, the latest SI information per cell; and replaying, by the coordinating server, the eNodeB with the stored SI information using a MME direct information transfer S1 message.

    Abstract: A method of determining a lower bound on users' speed for efficient SRS resource handling for MU-MIMO transmission includes determining an eNodeB (eNB) or gNodeB (gNB) timing of a subframe; determining a User Equipment (UE) timing of the subframe; calculating a timing advance type corresponding to a Round Trip Time (RTT); calculating a distance to a base station corresponding to the Round Trip Time (RTT); calculating a distance traveled by a UE between two points based on the distance to the base station; calculating a user speed based on the distance traveled by the UE; deriving a lower bound based on the user speed; and filtering users that exceed the lower bound on user speed. The filtered users may be not assigned SRS. The non-filtered users may be assigned SRS and may subsequently be sent MU-MIMO transmissions.
