    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.

    Abstract: A method is disclosed of providing dynamic Physical Downlink Control Chanel (PDCCH) power allocation, comprising: dividing a transmit power over all resource elements (REs) in a subframe at a first symbol time; determining how many REs will be in use at a second symbol time; determining how much additional power will be available at the second symbol time; and dividing and allocating at least a portion of the determined additional power over REs assigned for PDCCH resources for use during the second symbol time.

    Abstract: A method is disclosed for enhancing downlink link adaptation (DLLA) for spectral efficiency maximization, comprising: providing an outer loop link adaptation (OLLA) routine with a first path for a first transmission mode and a second path for a second transmission mode; modifying, upon receiving a retransmit message for a first transmission with the first transmission mode, a first offset coefficient; modifying, upon receiving a second retransmit message for a second transmission with the second transmission mode, a second offset coefficient; and calculating a modulation and coding scheme (MCS) offset for the first transmission based on the first offset coefficient.

    Abstract: A method of providing a full adaptive target BLER is described. In one embodiment, a method includes defining a first threshold; defining a second threshold; when voice traffic services are enabled, then setting the second threshold to a predetermined value; and when voice traffic service are not enabled, then setting the second threshold to a value corresponding to a current Signal to Interference and Noise Ratio (SINR) value.

    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: Methods are disclosed for an adaptive Transmit Time Interval (TTI) Bundling Configuration using a measurement gap. In one embodiment the method includes scheduling allocation of a TTI bundle wherein part of the TTI bundle overlaps a measurement gap; transmitting, by a User Equipment (UE), only a part of the scheduled TTI bundle; and scheduling other UEs to use the resources not used by the scheduled TTI bundle.
