Abstract: A user equipment (UE) supports communication over a first (lower) frequency range and a second (higher) frequency range. The UE determines an extent of preference of the second frequency range over the first frequency range, e.g., based on one or more of the following: sensor measurements; physical channel measurements; battery conditions; weather conditions; voice call activity; indoor/outdoor/in-car status; learned relationships between previous location-time conditions and performance on the second frequency range; etc. The UE device may control search activity and/or measurement activity on the second frequency range based on the preference extent, e.g., by controlling rates of repetition of search and/or measurement on the second frequency range, or by adding a measurement bias to a measurement reporting threshold, or by adding a delay to a measurement reporting time for a measurement, or by disabling search and measurement on the second frequency range.

Abstract: This disclosure relates to techniques for a wireless device to perform low latency communication using historical beam information. The wireless device may establish a radio resource control connection, and may subsequently release the resource control connection. The wireless device may store antenna element and beam information for the resource control connection. The wireless device may determine whether to use the stored antenna element and beam information when establishing another radio resource control connection. If the wireless device determines to do so, the wireless device may use the stored antenna element and beam information when establishing that radio resource control connection.
