Embodiment Construction

[0048] Certain wireless communication systems support Packet Data Convergence Protocol (PDCP) replication, eg, for carrier aggregation (CA) and / or for dual connectivity (DC). For example, in a CA scenario, a base station may configure two or more component carriers (CCs) for use by a user equipment (UE), and the UE may repeat PDCP protocol data unit (PDU) packets on each carrier. Packet replication can be used, for example, to improve the reliability of packet delivery.

[0049] Certain wireless communication systems may also support vehicle-based communications. Vehicle-based communication may include direct communication between the UE and the base station and / or may include side-link communication between vehicle-based UEs. In some examples, resources for sidelink communication can be scheduled by the base station, or can be pre-configured and used autonomously by the UE. However, conventional wireless communication systems are not configured to support or otherwise allow...

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a profile for vehicle-based sidelink communications supports packet duplication usinga set of carrier frequencies. The UE may transmit a request to a base station for resources to use to perform the vehicle-based sidelink communications, the request comprising an indication of the profile, a reliability metric associated with the profile, and an identifier that identifies the set of carrier frequencies. The UE may receive one or more grants from the base station for semi-persistent scheduling resources allocated on the set of carrier frequencies in response to the request.

Description

[0001] Cross References to Related Applications [0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 62 / 631,445, filed February 15, 2018, by Wu et al., entitled "Network-Assisted Scheduling for Packet Duplication in Vehicle-Based Sidelink Communication"; U.S. Patent Application No. 16 / 270,538, entitled "Network-Assisted Scheduling for Packet Duplication in Vehicle-Based Sidelink Communication," filed February 7, 2019; each of the foregoing U.S. Patent Applications is assigned to the present assignee. Background technique [0003] The following relates generally to wireless communications, and more specifically to network assisted scheduling for packet replication in vehicle-based sidelink communications. [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems can support communication with multiple us...
