Abstract: The present disclosure provides a method and a device used in a User Equipment (UE) and a base station for wireless communications. The UE receives a first signaling; and transmits a first radio signal; wherein the first signaling comprises scheduling information of the first radio signal; the first signaling is used to determine a first index, and the first index is used to determine a transmitting antenna port of the first radio signal; transmit power of the first radio signal is first power, and a linear value of the first power is equal to a product of a linear value of second power and a first coefficient; the first coefficient is one of K candidate coefficients. The above method optimizes Uplink transmit power according to the UE's own capabilities.

Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.

Abstract: Techniques for integrating disparate headend traffic ingress services with disparate backend services are disclosed herein. The techniques may include receiving, at a classification and forwarding node of a networked computing environment, a data packet encapsulated according to a first encapsulation protocol that is supported by the classification and forwarding node.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems may support beamformed transmissions between devices (e.g., to improve coverage range). The beamformed transmissions may depend on discovery and maintenance of receive and transmit beams over which a given device may communicate with another device. Various receive and transmit beams for a given device may be compared using reference signals. As the number of devices attempting to access a cell increases, the number of reference signals to be transmitted may scale proportionally. Large numbers of reference signals may flood time-frequency resources of the system and/or require excessive processing at a mobile device. Scrambling sequences for reference signals may be employed to improve efficiency of resource usage. In aspects, the scrambling sequences may be implicitly determined (e.g., based on resources over which the access request was transmitted).

Abstract: Different approaches that aim to extend scan range of phased array antennas by means of altering surface waves and/or altering the coupling are disclosed. One approach includes providing a phased array antenna where a surface of a substrate that houses antenna elements of the array includes openings such as trenches or grooves. Such openings in the surface effectively reduce the dielectric constant of the substrate, are easy to manufacture, and may reduce or eliminate the need to use exotic and expensive low-k dielectric materials. Another approach includes providing a phased array antenna where antenna elements are disposed over a substrate in the form of surface mount (SMT) components that are reduced in size/footprint. Using SMT antenna elements with a reduced size allows achieving the same gain while spacing antenna elements farther apart with gaps in between the antenna elements, thus also reducing the overall dielectric constant of the substrate.
