Abstract: Aspects directed towards communications for random access procedures are disclosed. In one example, a first beam and a second beam may be available for communications between a scheduled entity and a scheduling entity. The scheduling entity may send, and the scheduled entity may receive, a message 1 transmission for a random access procedure on the first beam. The scheduled entity may open a random access response (RAR) window to monitor for a message 2 transmission according to a predetermined sequence designating whether to monitor the first beam, the second beam, or some combination thereof. The scheduling entity may send, and the scheduled entity may receive, the message 2 transmission on the first beam or the second beam as designated by the predetermined sequence. Other aspects, embodiments, and features are also included.

Abstract: The present disclosure presents a method and an apparatus for planning interference measurement resources (IMRs). For example, the example method may include assigning a transmission group identifier to a cell in a wireless network, mapping the transmission group identifier assigned to the cell to a corresponding transmission pattern of a combination of zero power (ZP) and non-ZP (NZP) channel state information-reference signals (CSI-RSs) transmitted from the cell and neighbors of the cell, and receiving, at the cell, a CSI report from a user equipment (UE) in communication with the cell, wherein the CSI report is received from the UE based at least on an interference measured by an IMR at the UE corresponding to the transmission pattern. As such, IMR planning may be achieved.

Abstract: The present disclosure presents a method and an apparatus for coordinated scheduling at a cell. For example, the example method may include receiving a plurality of channel state information (CSI) reports from one or more user equipments (UEs) served by the cell, generating a plurality of cell reports based at least on the plurality of CSI reports received from the one or more UEs, transmitting the plurality of cell reports to a central scheduling entity, receiving a selected global transmission configuration, receiving one or more additional CSI reports from the one or more UEs subsequent to transmitting the plurality of cell reports to the central scheduling entity, and identifying a UE of the one or more UEs to serve based at least on the selected global transmission configuration and the one or more additional CSI reports. As such, coordinated scheduling at a cell may be achieved.
