Abstract: Base stations and user terminals may adaptively configure a digital precoder codebook for mmWave-based hybrid beamforming, such as by determining at least one analog beamformer and combiner, determining at the user terminal a lowest codebook resolution of digital precoding that can be used to achieve at least one performance parameter, and communicating to the base station the determined lowest codebook resolution of digital precoding. The adjustment of digital precoder codebook resolution, on top of analog beamforming, across different radio resources (e.g. time/frequency) may optimize feedback efficiency for a user terminal. In some cases, the user terminal may also receive from a base station an assistance parameter relating to an achievable performance gain using digital precoding. The user terminal may use the received assistance parameter in determining the digital precoder codebook resolution.

Abstract: Methods, apparatuses, systems, etc., directed to resource solicitation for Fog Radio Access Network (RAN) are disclosed herein. For some embodiments, a wireless transmit receive unit (WTRU) may receive a Fog-Resource Solicitation, for example included in a paging message, for joining a Fog Radio Access Network (RAN) platform (e.g., soliciting resources). The WTRU may accept or decline the Fog-Resource Solicitation, for example, based on any of the solicited resources and the WTRU status. In case the WTRU accepts the fog-Resource Solicitation, the WTRU may establish a connection to the RAN for indicating an acceptance of the Fog-Resource Solicitation. In case the WTRU declines the Fog-Resource Solicitation, the WTRU may ignore the Fog-Resource Solicitation or respond to the Fog-Resource Solicitation by establishing a connection to the RAN, indicating a declination of the solicitation. For some embodiments, a WTRU may trigger sending a RRC-Connection Release Request to e.g.
