Abstract: Techniques for co-existence between wireless Radio Access Technologies (RATs) are disclosed. During an active period of a Discontinuous Transmission (DTX) communication pattern, a first signal may be transmitted during a first subframe and a second signal may be transmitted during a second subframe, while during an inactive period the first signal may be transmitted during the first subframe and the second signal may be omitted during the second subframe. Retransmission of one or more packets may take place over a subset of less than all retransmission opportunities based on the DTX communication pattern. A Secondary Cell (SCell) may be reconfigured as the Primary Cell (PCell) and the PCell may be reconfigured as the SCell for one or more access terminals based on a load balancing condition or a channel selection condition.

Abstract: Aspects described herein generally relate to communicating between a user equipment (UE) and a cell using frequency division duplexing (FDD) to separate an uplink frequency band and a downlink frequency band with the cell. An indicator can be transmitted from the cell and received by the UE to implement time division duplexing (TDD) on the uplink frequency band. Based at least in part on the indicator, communicating between the UE and the cell can include separating the uplink frequency band into a plurality of downlink subframes for receiving downlink communications from the cell and a plurality of uplink subframes for transmitting uplink communications to the cell.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a duration of a dormancy timer for switching from an active bandwidth part to a dormant bandwidth part configured for the UE; start or restart the dormancy timer based at least in part on a determination that a condition is satisfied; and switch to the dormant bandwidth part based at least in part on a determination that the dormancy timer has expired. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control signaling indicating a configuration for establishing a dual connectivity connection. The dual connectivity connection may include a wireless local area network (WLAN) link and a cellular network link. The UE may establish the WLAN link or the cellular network link as a primary link of the dual connectivity connection. The primary link may be reconfigurable between the WLAN link and the cellular network link. The dual connectivity connection may support a single radio resource control connection associated with the primary link between the UE and the network entity. The UE may communicate with the network entity using at least the primary link of the dual connectivity connection. The UE may support a single radio resource control state of the plurality of radio resource control states at a time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a system information block, a paging message, or both. The UE may determine a priority level associated with relaying the system information block, the paging message, or both on a sidelink channel. The UE may transmit, to a second UE on the sidelink channel, the system information block, the paging message, or both based on the priority level.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may be configured to communicate with a first base station, where the first UE is configured to relay wireless communications between a second UE and the first base station via at least a sidelink communication link between the first UE and the second UE. The first UE may receive, from the first base station, an indication for the first UE to perform a first handover procedure from the first base station to a second base station. The first UE may transmit, to the second UE via the sidelink communication link and based on receiving the indication to perform the first handover procedure, a sidelink transmission including a trigger for the second UE to perform a second handover procedure or a reselection procedure. The first UE may then communicate with the second base station based on performing the first handover procedure from the first base station to the second base station.

Abstract: Methods, systems, and devices for wireless communications in a multiple bandwidth part environment are described. In response to a serving beam failure in an active bandwidth part, the UE may determine a level of support provided by the active bandwidth part for a random access procedure, and may determine a contingency (e.g. fallback) bandwidth part that supports the random access procedure. In some cases, the UE may identify the contingency bandwidth as an initial bandwidth part used by the UE for a prior random access procedure. In some cases, the base station may send to the UE, an explicit indication of the contingency bandwidth part. In some cases, the UE may identify the contingency bandwidth part based on a reference signal. Upon determining the contingency bandwidth part, the UE may perform the random access procedure using the contingency bandwidth part.

Abstract: A method of wireless communication for a user equipment (UE) includes entering a dormancy period for a secondary cell group (SCG) of a base station (BS) during which no downlink (DL) data or control transmissions are received from the SCG; performing a channel state information (CSI) measurement on the SCG during the dormancy period to generate a measurement report; determining an uplink (UL) beam of a primary secondary cell (PSCELL) of the SCG; transmitting the measurement report to the BS on the UL beam of the SCG; and determining, during the dormancy period and after transmitting the measurement report, one or more downlink (DL) beams for communicating on the SCG based on one or more rules and based on the measurement report, wherein the one or more rules result in the BS determining the same one or more DL beams based on the measurement report.
