Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic beamforming in control channels, by transmitting downlink control channels to user equipment (UEs) in a number of orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A first OFDM symbol of the number of OFDM symbols can be transmitted using first beamforming parameters in a first direction, and a second OFDM symbol of the number of OFDM symbols can be transmitted using second beamforming parameters different from the first beamforming parameters and in a second direction different from the first direction. The number of OFDM symbols used, as well as other parameters, can be dynamically adjusted in subsequent subframes. Other embodiments are described.

Abstract: Devices for and methods of synchronous beam refinement using a beam refinement reference signal (BRRS) are generally described. In one example embodiment, a UE receives BRRS information indicating switching of a Tx beam. The UE then uses this information to switch an associated Rx beam. In some embodiments, timing information is used to match the switching times. In some embodiments, DCI and CSI-RS operations are used to determine switching for the synchronous beam refinement.

Abstract: Provided herein are method and apparatus for perform radio link monitoring (RLM) based on a Reference signal (RS). An embodiment provides a user Equipment (UE) comprising circuitry configured to: decode a Reference Signal (RS) received from an access node; and determine beam quality for one or more beam pair links (BPLs) of the RS between the UE and the access node based on the decoded RS, wherein each of the BPLs comprises a transmit (Tx) beam of the access node and a receive (Rx) beam of the UE. Also provided is a procedure of RLM. At least some embodiments allow for beam recovery request for UE beam refinement, and allow for determining whether radio link failure (RLF) occurs.

Abstract: Technology for decreasing latency for contention based scheduling request (SR) is disclosed. A user equipment (UE) can randomly select a physical random access channel (PRACH) preamble index for a PRACH transmission. The UE can multiplex the PRACH preamble index together with a SR message containing a cell radio network temporary identifier (C-RNTI) and a buffer status report (BSR) for the PRACH transmission. The UE can process, for transmission, to an enhanced node B (eNB), the PRACH preamble index multiplexed with the SR message in a subframe #(n) of the PRACH transmission, wherein n is a subframe number.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing full-dimension multi-input multi-output (FD-MIMO) and providing collision reduction by transmitting data to an evolved Node-B (eNB) on an uplink (UL) resource; and receiving an acknowledgement (ACK) or negative acknowledgment (NACK) on a physical HARQ-ACK indicator channel (PHICH), responsive to transmitting the data on the UL resource. The PHICH may be mapped to a least physical resource block (PRB) that is offset by a PHICH offset. The PHICH offset may include a group offset and a sequence offset relative to a transport block (TB) index and first PRB index of a corresponding uplink shared channel. Other embodiments are described.
