Abstract:
Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a user equipment and/or base station) may select a beam configuration for a wireless transmission over a channel of a radio frequency spectrum band. The wireless device may perform a listen-before-talk (LBT) procedure on the channel using a LBT detection threshold, wherein the LBT detection threshold is based at least in part on the selected beam configuration. The wireless device may perform the wireless transmission over the channel using the selected beam configuration based at least in part on a success of the LBT procedure.
Abstract:
Systems and methods of QoS-aware admission control for networks including heterogeneous data traffic types is provided. Embodiments of the present disclosure take into account one or more connection parameters for several data flows within a network in determining whether sufficient resources are available to admit a new flow into the network, accounting for different quality-of-service (QoS) requirements arising from the heterogeneity of the traffic types. Moreover, various embodiments traverse different adjustment options for connection parameters, termination options, or combinations of both to identify the optimal set of flows and connection parameters to achieve bandwidth efficiency while ensuring that lower ranked data flows are not admitted at the expense of higher ranked flows.

Abstract:
The embodiments herein provide a method and apparatus for scheduling users of a communication system, based on an advantageous pre-scheduling scheme. As a first scheduler process during a current scheduling interval, first users selected for scheduling in the current scheduling interval are regularly scheduled to thereby make radio resource reservations for the first users. As a second scheduler process during the current scheduling interval, second users not among the first users are identified as having scheduling deadlines falling in a subsequent scheduling interval. As a further operation of the second scheduler process, the second users for the subsequent scheduling interval are prescheduled to thereby make radio resource reservations in the subsequent scheduling interval for the second users. The second scheduling may be performed using processing resources that would otherwise be left idle by the first scheduler process during the current scheduling interval.
Abstract:
Diverse traffic types can be efficiently communicated in a simultaneous manner by dynamically selecting between contention-based and scheduling-based media access control (MAC)communication schemes.Such a mechanism may be particularly beneficial in networks having a contention-based access resources and scheduling based access resources.Contention- based resources and scheduling based resources may occur over a common period,and may be orthogonal in the frequency domain and/or in the code domain.The dynamic selection may be based on a traffic characteristic or a network characteristic,and may be performed on a packet- by-packet basis.The selection criteria may be updated dynamically to adapt to changing network conditions,and may be communicated to the various transmitters via control channels or higher layer signaling.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. In one configuration, the apparatus may be a UE. The UE determines an MCS that would facilitate interference suppression of an interfering first cell transmission from a first cell when decoding a second cell transmission from a second cell at the UE. The interfering first cell transmission is a transmission unintended for the UE. The second cell transmission is a transmission intended for the UE. The UE transmits information indicating the determined MCS for the first cell. The UE receives a transmission including the second cell transmission from the second cell and the interfering first cell transmission from the first cell. The UE demodulates and/or decodes the second cell transmission from the received transmission based on the determined MCS.
