Abstract: Methods, systems, and devices for wireless communication provide for split symbol control by varying tone spacing and symbol duration for control channels in a subframe. The control symbols may be transmitted at various locations within the subframe and may be transmitted to different mobile devices. In some examples, multiple control symbols may be transmitted in a subframe to multiple mobile devices depending on the capabilities of each of the multiple mobile devices.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system operating in millimeter wave (mmW) spectrum may utilize synchronization signals for beam tracking. A synchronization signal (e.g., primary synchronization signals (PSS), secondary synchronization signals (SSS), etc.), beam reference signal, and/or control signal may be designed to facilitate beam tracking. A synchronization signal structure based on a repeated sequence in the time domain may facilitate searching for different beams in a timely manner. In some cases, the repeated synchronization signal structure may be achieved by using a larger tone spacing, and hence having shorter symbol duration and repeating the short symbols in the time domain. The repeated structure may be further used to encode additional information (e.g., facilitated by the resulting additional degrees of freedom). Additionally or alternatively, a synchronization signal (e.g., SSS) may be discrete Fourier transform (DFT) pre-coded to achieve better peak-to-average-power-ratio (PAPR).

Abstract: The apparatus may be a base station. The apparatus processes a first group of synchronization signals. The apparatus processes a second group of synchronization signals. The apparatus performs a first transmission by transmitting the processed first group of the synchronization signals in a first synchronization subframe. The apparatus performs a second transmission by transmitting the processed second group of the synchronization signals in a second synchronization subframe.

Abstract: A UE may select a first beam for communication with a base station. The UE may attempt, through the selected first beam, at least one RACH procedure with the base station. The UE may determine that the at least one RACH procedure failed with the base station. The UE may send, after a successful RACH procedure with the base station, information indicating that the at least one RACH procedure failed. In an aspect, the UE may select a new beam for communication with the base station after the determination that the at least one RACH procedure failed, and at least a portion of the successful RACH procedure may be performed through the selected new beam.

Abstract: A UE may receive, from a base station, a message requesting BSI. The UE may determine a number N of BSI reports to send to the base station, and each BSI report may indicate a beam index corresponding to a beam and a received power associated with the beam. The UE may send, to the base station, N BSI reports based on the message requesting BSI. The UE may receive, from the base station, a set of signals through a set of beams, and determine the received power for each signal of the set of signals received through each beam of the set of beams, each received power may be associated with a beam of the set of beams.

Abstract: A first apparatus may transmit, to a user equipment (UE), on a control channel, one or more indications of one or more beam indexes corresponding to one or more beams. The first apparatus may transmit, to the UE, one or more reference signals through the one or more beams corresponding to the one or more beam indexes. The reference signals may be used by the UE to select a best subarray and/or receive combiner for communication with the first apparatus.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a subframe that includes physical broadcast channel (PBCH) signals interspersed within beam reference signals, where the subframe may be a synchronization subframe including one or more synchronization signals. In some cases, the beam reference signals from different antenna ports may be code division multiplexed or frequency division multiplexed over multiple frequency tones. A user equipment (UE) may use the beam reference signals to generate channel estimates for the PBCH signals. In some cases, orthogonal cover codes for code division multiplexed signals may be selected to facilitate generation of channel estimates for PBCH signals transmitted using nearby frequency tones.
