    Abstract: An apparatus of a user equipment (UE) comprises one or more baseband processors to generate a beam failure recovery request to be transmitted to a Fifth Generation (5G) NodeB (gNB) over a physical random access channel (PRACH), to process a response from the gNB, and to generate a physical uplink control channel (PUCCH) transmission to be transmitted to the gNB using a default spatial relation comprising a same spatial filter as used for the beam failure recovery request transmission over the PRACH. A beam failure recovery request is to be transmitted to a gNB after a random access response from the gNB, wherein the beam failure recovery request is to be transmitted via Message 1 or Message 3 to the gNB, and a response is to be received from the gNB via Message 2 or Message 4.

    Abstract: Techniques for full duplex operation of base stations and/or user equipments (UEs) are discussed. One example embodiment comprises one or more processors of a UE configured to: process control messages that comprise a downlink assignment for the UE and an uplink grant for the UE during a subframe in a frequency band, wherein the downlink assignment indicates a first set of UE subarrays, and wherein the uplink grant indicates a second set of UE subarrays; process downlink data received via transceiver circuitry via the first set of UE subarrays, wherein the downlink data is received from a first base station during the subframe via the frequency band; and output uplink data to the transceiver circuitry for transmission via the second set of UE subarrays, wherein the uplink data is output for transmission to a second base station during the subframe via the frequency band.

    Abstract: Devices and methods of determining offsets for different eNBs in a dynamic switched CoMP network are generally described. A UE may receive, in an RRCConnectionReconfiguration message, DL parameter sets associated with different eNBs and having reference signal information for a PSS, SSS and DRS. The UE may receive reference signals based on the DL set associated with the eNB and determine a timing/frequency offset based on the reference signals. The offsets may be used to decode a dynamically switched PDSCH indicated by a PDCCH. The DL sets may indicate which PDCCH to detect or the PDCCH from the same eNB may be used and the PDSCH determined from a DCI in the PDCCH. A UL DCI may indicate which of UL parameter sets to use. The UL sets may indicate a reference signal to determine path loss and a timing advance value.

    Abstract: Systems and technologies described herein provide functionality for a cellular base station to dynamically indicate a reception (Rx) beam to be used by a user equipment (UE). The Rx beam can be indicated explicitly or implicitly. The UE can, for example, use the Rx beam for Physical Downlink Shared Channel (PDSCH) reception, Channel State Information Reference Signal (CSI-RS) measurements, and/or Channel State Information (CSI) calculation at the UE. Systems and technologies described herein are generally useful for systems that use multiple transmission (Tx) beams and/or that support Coordinated Multipoint (CoMP) transmission technology.
