    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may account for propagation delay when initiating a random access (RACH) procedure. For example, the UE may determine transmission timing for a RACH preamble based on an estimated propagation delay, such that the RACH preamble is received at a base station approximately at the beginning of a slot. To support reliable communication of the RACH preamble, the UE may implement a timing offset. In some examples, the base station may configure the UE with the timing offset using system information. Alternatively, the UE may be pre-configured with the timing offset. By determining the transmission timing for the RACH preamble further based on the timing offset, the UE may ensure that the RACH preamble is received at the base station after a slot boundary (e.g., avoiding causing interference to communications in a previous slot).

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a wireless network device (e.g., a base station or a transmission reception point (TRP) of the base station), a first control message comprising an indication of a set of energy saving modes of the wireless network device. The UE may receive a second control message indicating a first energy saving mode from the set of energy saving modes, where the first energy saving mode may be indicative of a number of channel state information (CSI) reference signal (CSI-RS) resources used by the wireless network device. The UE may monitor one or more of the CSI-RS resources for a CSI-RS in accordance with the first energy saving mode, and transmit, to the wireless network device, CSI feedback determined based on measurements made by the UE of the CSI-RS.
