Abstract: Devices and methods of beamforming are generally described. A UE transmits to an eNB a BRSRP report having selected BRSRP values and associated BRS IDs. An active link list, a CSI resource indication, and a first active link are used to measure the CSI resource and CSI feedback is sent. A serving link ID is provided to indicate a second active link to use for control and data reception. Rx beams are trained based on multiple instances of each BRS and the eNB supplies selection criteria for the BRSRP report. The Rx beams are refined based on BRRS and the second active link is dependent on BRRSRP or CSI feedback. When configured for dual beam operation, the BRSRP feedback corresponds to BRSRP value pairs and dual Rx beams associated with a pair of serving link IDs are used.

Abstract: Techniques for transmit power control calculation by user equipments (UEs) are discussed. An example apparatus employable by a UE comprises a processor configured to: configure, for each active link of a set of active links, a distinct set of power control parameters, wherein each active link comprises a distinct combination of a UE beam of a set of UE beams and a transmission/reception point (TRP) beam of a set of TRP beams; process an uplink (UL) grant received via a control channel that indicates a first active link of the set of active links, wherein the first active link comprises a first UE beam and a first TRP beam; calculate a first transmit power based at least in part on the distinct set of power control parameters configured for the first active link; and output UL data for transmission via the first UE beam at the first transmit power.

Abstract: The first circuitry may be operable to establish a first UE Receive (Rx) beam as being for reception of data from a first eNB. The second circuitry may be operable to process a transmission including Downlink Control Information (DCI), wherein the DCI carries an eNB cell-switching indicator. The first circuitry may also be operable to establish a second UE Rx beam as being for reception of data from a second eNB based on the eNB cell-switching indicator.

Abstract: A receiver processes a data signal and provides an acknowledgement within a turnaround time through use of code block alignment, reduced complexity or increased processing time. In a first embodiment, a radio access network (RAN) node enables encoded information to be segmented into multiple code blocks and maps a group of code blocks to be aligned with orthogonal frequency division multiplexing (OFDM) symbol boundaries such that efficient receiver processing can implement processing pipelining. In a second embodiment, the transmitter can provide more time or reduce the complexity of the packet, such as by repetition of bits of code blocks of the encoded information or by reserving resource elements (REs) such that the receiver has effectively more time (or less complexity) to process the last or last few code blocks of the packet.
