Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, CC1 may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and CC2 may be an assisting carrier such as a sub-6 GHz carrier. In a first example, a UE may trigger beam recovery for CC1 (on CC2), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on CC2. In a second example, a new scheduling request (SR) may be defined on CC1 for CC2 beam recovery. In a third example, RACH resources or procedures on CC2 may be used to perform the beam recovery for CC1.

Abstract: DM-RS symbols may be inserted in the beginning of a subframe, or in two parts of the subframe. In one aspect, a method, a computer-readable medium, and an apparatus for dynamically conveying DM-RS information are provided. The apparatus may be a base station. The apparatus may determine the number of DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols. The apparatus may transmit the number of the DM-RS symbols and/or the locations within the subframe for transmission of the DM-RS symbols to a UE. In another aspect, a UE may receive the number of DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols from a base station. The UE may decode the DM-RS symbols from the subframe based on the number of the DM-RS symbols and/or the locations within a subframe for transmission of the DM-RS symbols.

Abstract: Beam specific power ramping counters may be used to adjust uplink transmit power. For example, a user equipment (UE) may use counters for beam specific power control of Random Access Channel (RACH) Message1 transmissions. A UE may transmit a RACH message1 on a beam specific resource and increment a counter corresponding to a gNB downlink beam. Power adjustments may be made on subsequent re-transmissions of the RACH message1 according to a power control policy. The power control policy may call for applying a power ramping function based on the value(s) of one or more of the counters.

Abstract: Certain aspects of the present disclosure provide techniques for use of SS transmitted using a UE-specific configuration of time-frequency resources. A BS may assign at least one UE-specific configuration, wherein the UE-specific configuration comprises an allocation of resources for a UE-specific SS for mobility management purposes. The BS may communicate with the UE based, at least in part, on the UE-specific configuration. A UE may correspondingly receive the UE-specific configuration and communicate with a BS based, at least in part, on the configuration.

Abstract: An apparatus are provided for wireless communication at a base station with improved PBCH construction and decoding. The base station apparatus constructs a PBCH payload, wherein a bit location is selected for encoding a plurality of bits of the PBCH based on an estimated reliability for the corresponding bits location wherein the plurality of bits comprises frozen bits, unknown bits that are unknown to a user equipment, and potentially known bits that are potentially known by the user equipment. The apparatus transmits the PBCH payload in at least one of a plurality of SS blocks. A UE receiving the PBCH decodes the PBCH based on a successive decoding order. The successive decoding order may be based on an estimated reliability for the corresponding bits, e.g., in which potentially known bits are decoded prior to unknown bits.
