Abstract: Certain aspects of the present disclosure relate to methods and apparatus for multiplexing new radio (NR) physical broadcast channels (NR-PBCHs) with NR synchronization signals. An exemplary method that may be performed by a wireless node includes determining a frequency offset to use in transmitting one or more synchronization signals and one or more physical broadcast channels (PBCHs) and transmitting the one or more synchronization signals, using a synchronization signal (SS) transmission band having an SS center frequency, and the one or more PBCHs, using a PBCH transmission band having a PBCH center frequency that differs from the SS center frequency by the determined frequency offset.

Abstract: In wireless communication systems that support 5G or NR protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the PDCCH) and a data channel (e.g., the PDSCH). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating synchronization signals for cell synchronization. Certain aspects of the present disclosure provide a method for wireless communication. The method generally includes determining a symbol index for transmitting a sequence; determining an amount of cyclical shift in one of a frequency domain and a time domain to apply to the sequence, wherein the amount of cyclical shift in the frequency domain is based on the sequence and the symbol index; shifting the sequence by the amount of cyclical shift; and transmitting the shifted sequence in a symbol corresponding to the symbol index.

Abstract: During device-to-device communication between two devices, a communication transmitted from a first UE to a second UE may not be reliably received by the second UE if the first UE is traveling at high speed. Therefore, a travel speed of a transmitting UE may be considered in determining a transmission configuration. According to an aspect, the UE may determine a travel speed of the UE. The UE may determine, based on the travel speed of the UE, a transmission configuration of the UE for device-to-device communication. The UE may transmit the device-to-device communication based on the transmission configuration.

Abstract: A procedure to select a UE as a relay between a machine-type communication (MTC) device and a base station is desired to improve communication between the MTC device and the base station. The apparatus may be a machine-type communication user equipment (M-UE). The apparatus transmits, to one or more user equipments (UEs), an access request to request access to a base station through one or more of the one or more UEs as a relay. The apparatus receives an access request response from the base station, the access request response including selection information about selection of at least one of the one or more UEs as a relay between the M-UE and the base station.
