Abstract: A method of wireless communication by a base station includes configuring a tracking reference signal (TRS) with respect to a physical downlink shared channel (PDSCH) for an idle/inactive mode user equipment (UE). The method also transmits the tracking reference signal and the PDSCH during a paging cycle, in accordance with the configuration. A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to communicate with a base station on different channels or messages with different processing timelines. In order to prevent a collision between processing communications associated with the different length TTIs, the UE may drop one or more communications on corresponding channels with longer processing timelines to receive and/or process the transmission on the channel with a shorter processing timeline. Additionally, the UE may transmit uplink control information (UCI) for the one or more dropped communications, where the UCI may include hybrid access request (HARQ) acknowledgement/negative acknowledgement (ACK/NAK) feedback, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), etc. If a downlink transmission is dropped, the UE may transmit a NAK message. Alternatively, if an uplink transmission is dropped, the UE may transmit at least a portion of the UCI.

Abstract: A wireless device can flexibly switch between different frequency-division duplexing (FDD) modes including one or more half-duplex (HD) FDD modes and a full-duplex (FD) FDD mode in wireless communication. The wireless device can intelligently switch between the FDD modes to meeting different requirements of power consumption, traffic latency, and/or coverage enhancement.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may dynamically cancel and reschedule configured transmission occasions for communicating with a user equipment (UE). The transmission occasions may be configured according to a semi-persistent scheduling (SPS) configuration (e.g., for downlink transmissions) or a configured grant (CG) configuration (e.g., for uplink transmissions). The base station may transmit a dynamic grant to the UE that indicates a cancellation of a transmission occasion and schedules a dynamic transmission occasion for communicating data scheduled for transmission at the canceled transmission occasion. In some examples, the cancellation in the grant may be explicit or implicit.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: Techniques are described for wireless communication. A first method may include receiving at a user equipment (UE) over an unlicensed radio frequency spectrum band an indication of a time window associated with a transmission of a synchronization signal, and monitoring the unlicensed radio frequency spectrum band during the time window to receive a synchronization signal from a base station. A second method may include transmitting an indication of a time window associated with a transmission of a synchronization signal; performing a plurality of clear channel assessments (CCAs) on an unlicensed radio frequency spectrum band during the time window; and transmitting the synchronization signal over the unlicensed radio frequency spectrum band at a transmission time during the time window. The transmission time may be based at least in part on a result of at least one of the CCAs.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.
