Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support configuring timing advance in a radio access network. The method includes defining a timing advance configuration for a radio access network that employs a modulation scheme with scalable numerology, determining timing advance parameters consistent with the timing advance configuration for a user equipment (UE) that is in communication with the radio access network, and transmitting the timing advance parameters to the UE during an initial access procedure involving the UE or while the UE is in a connected state in the radio access network. The timing advance configuration may be defined to accommodate a numerology used by the radio access network.

Abstract: A new radio (NR) bit prioritization procedure that may be executed by a UE and a base station is disclosed, resulting in transmission and reception of modulation symbols having prioritized bits. For example, a transmitter may encode a code block using low-density parity-check code to generate a stream of encoded bits. The transmitter may arrange the encoded bits in one or more modulation symbols according to a relative priority of the encoded bits. The highest priority bits may be located in the most significant bits of the modulation symbol, and therefore be less likely to experience errors. A receiver may receive the modulation symbols and reorder the encoded bits according to the coding scheme based on the relative priority prior to decoding the encoded bits. The prioritization of the bits within the modulation symbols may provide improved block error rates over sequential mapping of encoded bits to symbols.

Abstract: The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

Abstract: The present disclosure provides for enhanced pipeline processing using different timing characteristics for aggregated carriers. A receiving device may receive a first component carrier and a second component carrier from a transmitting device during a subframe including a first set of symbols on the first component carrier and a second set of symbols on the second component carrier. The first component carrier may be a priority component carrier having a different timing characteristic than the second component carrier. The receiving device may process, using a hardware processing pipeline, the first set of symbols interleaved with the second set of symbols. The receiving device may transmit an acknowledgment, within the subframe, based on the processing of at least all of the first set of symbols.

Abstract: In an embodiment, to avoid a misalignment between NCP and ECP symbols caused by an SCS, at least a portion of a CP of at least one ECP symbol is punctured, and at least one startpoint of at least one ECP slot carrying the at least one punctured ECP symbol is aligned with at least one startpoint of at least one NCP slot carrying at least one NCP symbol. In another embodiment, a symbol control channel is scheduled within an initial control part of a slot before any other symbols are scheduled, and NCP symbols and ECP symbols are scheduled in a remaining data part of the slot that is after the initial control part. In another embodiment, either endpoints or startpoints of NCP and ECP uplink symbols are aligned by extending the ECP uplink symbol or an ECP guard period.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: According to aspects, a BS may determine presence of a narrow GB or lack of a GB to separate a first RB used for DL transmission from the BS to a first UE and a second RB used for DL transmission from the BS to a second UE. In response to the determination, the BS may transmit, to the first UE, interference information associated with the transmission from the BS to the second UE. According to aspects, a BS may determine a presence of a narrow GB or lack of a GB to separate a first RB used for UL transmission from a first UE to the BS and a second RB used for UL transmission from a second UE to the BS. In response to the determination, the BS may transmit to the first UE, interference information associated with the UL transmission from the second UE to the BS.

Abstract: Aspects of the present disclosure provide methods and apparatus for beam selection in uplink-based and downlink-based mobility scenarios, for example, for new radio (NR) systems which can improve handover reliability, reduce handover frequency, and improve power efficiency. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes transmitting an uplink reference signal with an indication of a preferred downlink beam and receiving a downlink transmission based, at least in part, on the uplink reference signal.
