Abstract:
Methods and architectures to determine whether carrier aggregation (CA) component carrier signals transmitted or received by a user equipment (UE) device with a primary serving cell (PCell) and one or more secondary serving cells (SCell) exceed a maximum transmission timing difference compare a relative difference of signals derived from subframe boundaries, a subslot transmission time interval (sTTI) boundary or a combination thereof, with a maximum receive timing threshold value. In the uplink, timing advance groups (TAGs) for the PCell and/SCells may be compared by the UE to a maximum transmit timing threshold value. If the maximum thresholds are exceeded, the SCell may be dropped or changed to avoid UE from exceeding its power maximums.

Abstract:
Devices and methods of on-demand system information block (SIB) transmission are generally described. A user equipment (UE) can be configured to determine a beam index during a beam sweeping procedure, based on a signal quality metric associated with a received synchronization signal. The UE can encode for directional transmission based on the beam index, a random access procedure (RACH) preamble sequence. The RACH preamble sequence can include a system information request. The UE can decode system information configuration received in response to the system information request. The UE can initiate a RACH process using another RACH preamble sequence, based on the received system information configuration. The encoded RACH preamble sequence with the system information request can be transmitted multiple times using the preferred beam index.

The second circuitry may be operable to generate a Physical Random Access Channel (PRACH) transmission associated with a preferred eNB beam for transmission on the preferred UE beam. The third circuitry may be operable to process a Random Access Response (RAR) transmission carrying Timing Advance (TA) received through the preferred UE beam.

Abstract:
An apparatus of an eNB and related method encode a 5G grouped downlink (DL) transmission (GDLT), where the GDLT comprises a plurality of TDD subframes, including a first and second subframe via which a single PDSCH is transmitted. The apparatus encodes a PDCCH as a part of the GDLT and encodes the PDSCH as a part of the GDLT. The PDSCH comprises a plurality of PDSCH parts, including a first part that is included in the first subframe and a second part that is included in the second subframe. The apparatus initiates a transmission of the GDLT to a UE and then decodes feedback from the UE related to the GDLT while the GDLT is in progress. When the feedback is an ACK, the apparatus continues transmitting the GDLT, and when the feedback is a NACK or no feedback is received, the apparatus terminates the GDLT.

The UE includes memory and processing circuitry configured to generate a reporting message for an Evolved Node-B (eNB), the reporting message indicating a plurality oftransmit (Tx) beams as preferred Tx beams.
