    Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.

    Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to select N≥2 radio frequency carriers for UL transmission from M>N available radio frequency carriers and subsequently send UL transmissions to a cellular wireless network based on the configuration. The M available radio frequency carriers are divided into distinct TAGs, each TAG having a distinct timing advance value, and the N radio frequency carriers belong to a single TAG. The wireless device is further configured to switch to a second set of N UL radio frequency carriers, after an uplink switching gap time period, based on a TAG medium access control (MAC) control element (CE), received the cellular wireless network, which specifies a second TAG from which to select the second set of N UL radio frequency carriers.

    Abstract: An approach is described for a method for a base station in a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes determining base initial seeds and a time parameter. The method further includes generating actual initial seeds based on the base initial seeds and the time parameter; generating a Pseudo-Noise (PN) sequence based on one of the actual initial seeds; and generating a remote interference management reference signal (RIM-RS) sequence based on the PN sequence. The method further includes transmitting the RIM-RS sequence to a remote base station.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for generating a report result based on a set of measurements performed at measurement gaps during a reporting period. The set of measurements are performed on a reference signal at a first bandwidth part (BWP) or a second BWP when BWP switching is performed. The first BWP has a first measurement gap configuration, the second BWP has a second measurement gap configuration. The measurement gaps of the reporting period are configured according to a third measurement gap configuration that is determined based on the first measurement gap configuration and the second measurement gap configuration.
