Abstract: This disclosure provides systems, methods and apparatuses for channel load-based cell reselection procedures. In one aspect, a user equipment (UE) may identify a channel load and may perform a cell reselection procedure based on the channel load. For example, the UE may perform an intra-frequency cell reselection procedure, an inter-frequency cell reselection procedure, or an inter-radio access technology (RAT) cell reselection procedure.

Abstract: This disclosure provides systems, methods and apparatus for determining a target base station timing advance value between a user equipment (UE) and target base station in connection with a random access channel (RACH)-less handover procedure. In one aspect, the UE may determine the target base station's timing advance based at least in part on a timing difference between the target base station and the source base station and based at least in part on a timing offset associated with an uplink and a downlink of the UE. In some aspects, the target base station may determine the timing advance using an uplink reference signal of the UE. In some aspects, the UE may report a timing difference between the target base station and the source base station, and the source cell may determine a timing advance based at least in part on the timing difference.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for caching content at a network edge and providing the cached content to requesting UEs. An example method generally includes receiving, from a first UE, a request for content from a remote source, retrieving the content from the remote source and providing the content to the first UE, storing at least a portion of the content in a local cache at the base station, receiving a request for the content from at least a second UE, and retrieving the content from the local cache and providing the content to the at least the second UE.

Abstract: Communication using a radio access network (RAN) including a primary cell for license spectrum access and a secondary cell for unlicensed spectrum access may be improved to provide optimal performance while considering characteristics of the primary cell and the secondary cell. The apparatus may be a core network entity. The core network entity is connected to a RAN including a primary cell utilizing a licensed spectrum and a secondary cell utilizing an unlicensed spectrum. The core network entity determines an authorization for data traffic to be offloaded to the secondary cell based on data traffic characteristics. The core network transmits an indication of the authorization to the RAN.
