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: Technology for a user equipment (UE) operable to assist a Next Generation NodeB (gNB) for beamforming is disclosed. The UE can determine a covariance matrix for a channel between the UE and the gNB. The UE can quantize the covariance matrix to obtain a quantized covariance matrix. The quantized covariance matrix can include M best diagonal entries that are selected from the covariance matrix, wherein M is an integer. The UE can encode the quantized covariance matrix as feedback for transmission to the gNB.

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 cNB 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: Technology for a next generation node B (gNB), operable to use phase tracking reference signals (PT-RS) is disclosed. The gNB can identify a modulation and coding 5 scheme (MCS) for the UE for a bandwidth part (BWP) with a subcarrier spacing (SCS). The gNB can select a time density of the PT-RS based on the MCS. The gNB can select a frequency density of the PT-RS based on an allocated bandwidth in the BWP. The gNB can encode the time density and the frequency density, for the PT-RS for transmission to the UE in higher layer signaling.

Abstract: Methods, systems, and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) is configured to receive, in a first subframe, a physical downlink control channel or enhanced physical downlink control channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS) activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures, based on the SPS activation, a downlink (DL) assignment in a second subframe for receiving an SPS physical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. The UE determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE receives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE is configured for transmission mode 10 (TM10).

Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. If a higher layer parameter altMCS-Table is configured, and a physical downlink shared channel (PDSCH) is assigned by a downlink control information (DCI) format 1, 1B, 1D, 2, 2A, 2B, 2C, or 2D, the UE may, for some subframe/frame configurations, determine a number of physical resource blocks (PRBs) for the transport block as a maximum of: 1; and a floor function applied to a product of a total number of allocated PRBs, a parameter dependent on a special subframe configuration, and a scaling parameter. For other subframe/frame configurations, the UE may determine the number of PRBs for the transport block as a maximum of: 1; and the floor function applied to a product of the total number of allocated PRBs and the scaling parameter.

Abstract: Dynamic transmission of non-zero power channel state information resource signals and interference measurement resources is described. Such dynamic transmission reduces or eliminates a need to buffer and store channel and interference measurements The described approach also reduces the overhead due to transmission of those resources and enables flexible time-domain channel state information requests.
