Abstract: Processes, systems, and devices for wireless communications are described. A communication device may monitor a wakeup signal monitoring occasion in an inactive duration of a discontinuous reception (DRX) cycle. The communication device may transmit, in a first active duration of the DRX cycle, a channel state information (CSI) report on one or more resources based on monitoring the wakeup signal monitoring occasion. In some examples, the communication device may transmit an indication that the communication device requests reporting of the CSI report in the first active duration of the DRX cycle. The communication device may, in some examples, receive, in a second active duration of the DRX cycle, control information for the UE based on the CSI report.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, signaling indicating a channel state information (CSI) report configuration. The CSI report configuration may indicate a mapping between one or more CSI reference signal (CSI-RS) resources or one or more CSI-RS port groups and one or more antenna panels or antenna subpanels of the base station. The UE may generate CSI feedback based on the mapping. In some cases, the UE may generate the CSI feedback based on multiple hypotheses that correspond to CSI-RS measurements. In some examples, the multiple hypotheses may include a set of hypothesis groups based on one or more antenna panels or antenna subpanels of the base station. The UE may transmit a message reporting the CSI feedback to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a transmitting device may transmit a reference signal indicating a first service type supported by the transmitting device and a receiving device may receive the reference and determine whether to measure a signal strength associated with the reference signal based on determining whether the first service type supported by the transmitting device and a second service type supported by the receiving device are a same service type. For example, the receiving device may measure the reference signal if the first service type indicated by the reference signal and the second service type supported by the receiving device are the same service type. Alternatively, the receiving device may refrain from measuring the reference signal if the first service type indicated by the reference signal and the second service type supported by the receiving device are different service types.

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.
