    Abstract: Systems and methodologies are described that facilitate searches for a cell in a wireless communication environment. A mobile device can employ a searcher that can detect timing information respectively associated with PSCs and cells to determine the cell with the highest correlation. The searcher can detect SSCs, which can include detecting associated phase information, to determine the SSC with the highest correlation, CP length, and/or other information to facilitate identifying a desired cell having the strongest signal to establish communication between the mobile device and the desired cell. PSCs respectively associated with cells can have different positions in the symbol sequences, and SSCs can respectively be phase shifted at different angles to facilitate detection and identification of a cell(s), where a PSC can be utilized as a phase reference by the associated SSC.

    Abstract: A method of wireless communication includes receiving a first interference signal and a second interference signal. The method further includes determining whether the second interference signal includes a different version of the first interference signal. Additionally, the method includes combining the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal is the different version of the first interference signal.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a cell identifier is selected based on one or more properties associated with received downlink control information (DCI), where the properties may not be exclusively associated with determining a cell identifier. The cell identifier may be selected from a plurality of cell identifiers received through radio resource control signaling. The properties of the DCI may include a type of download control channel, a type of subframe and a type of DCI format used to provide the DCI.

    Abstract: This disclosure provides systems, methods, and apparatuses for a wireless node to receive a phase tracking reference signal (PTRS) transmitted inside a downlink random access channel (RACH) message. The wireless node may receive a downlink RACH message that includes a PTRS based on an indication received in a downlink RACH message or a physical downlink control channel (PDCCH) associated with a downlink RACH message. In some aspects, the wireless node may utilize the PTRS for phase error correction or frequency error correction (such as frequency error caused by Doppler effects). This disclosure also provides systems, methods, and apparatuses for a component of a base station to provide an indication that a PTRS is included in a downlink RACH message. The indication may be provided in a downlink RACH message or a PDCCH associated with a downlink RACH message.

    Abstract: Methods, systems, and devices for enhanced aperiodic sounding reference signal (A-SRS) scheduling are described. In some examples, a user equipment (UE) may transmit, to a base station, a capability message that indicates a capability of the UE to support dynamic scheduling of resources for an SRS. In some examples, the UE may receive, from the base station in response to the capability message, a downlink control message indicating a time domain allocation for the SRS and a frequency domain allocation for the SRS. In some examples, the UE may transmit the SRS using a set of resources in response to the downlink control message, the set of resources selected based at least in part on the time domain allocation for the SRS and the frequency domain allocation for the SRS.

    Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may receive a synchronization signal block or channel state information reference signal. The UE may transmit a channel state information report including a first indication of channel quality associated with the synchronization signal block or channel state information reference signal. The UE may receive a demodulation reference signal that is quasi co-located with the synchronization signal block or channel state information reference signal and associated with a physical downlink shared channel. The UE may transmit a hybrid automatic repeat request acknowledgment message or channel state information report including a second indication of channel quality associated with the demodulation reference signal of the physical downlink shared channel. The second indication of channel quality may include a differential measurement that is relative to the first indication of channel quality.

    Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive signaling indicating a configuration for the UE to communicate with a first transmission reception point (TRP) and a second TRP. The UE may receive a control signal identifying a set of channels sharing a common transmission configuration indication (TCI), where the common TCI may indicate a first TCI state for the first TRP and a second TCI state for the second TRP. The UE may communicate with at least one of the first TRP or the second TRP according to the common TCI based on receiving the control signal.
