TECHNICAL FIELD

The technology discussed below relates generally to wireless communication networks, and more particularly, to sidelink wireless communication in different frequency bands.

INTRODUCTION

In many existing wireless communication systems, a cellular network is implemented by enabling wireless user equipment to communicate with one another through signaling with a nearby base station or cell. As a user equipment moves across the service area, handovers take place such that each user equipment maintains communication with one another via its respective cell.

Another scheme for a wireless communication system is a device-to-device (D2D) network, in which wireless communication devices may signal one another directly, rather than via an intermediary base station or cell. D2D communication networks may utilize direct signaling (e.g., sidelink signaling) to facilitate direct communication between wireless communication devices. In some D2D configurations, wireless communication devices may further communicate in a cellular system, generally under the control of a base station. Thus, the wireless communication devices may be configured for uplink and downlink signaling via a base station and further for sidelink signaling directly between the wireless communication devices without transmissions passing through the base station.

One example of a sidelink wireless communication system is a vehicle-to-everything (V2X) communication system. V2X communication involves the exchange of information not only between vehicles themselves, but also between vehicles and external systems, such as streetlights, buildings, pedestrians, and wireless communication networks. V2X systems enable vehicles to obtain information related to the weather, nearby accidents, road conditions, activities of nearby vehicles and pedestrians, objects nearby the vehicle, and other pertinent information that may be utilized to improve the vehicle driving experience, increase vehicle safety, and support autonomous vehicles.

As the demand for sidelink communication increases, research and development continue to advance communication technologies. For example, technologies for communication across different frequency bands may be useful, particularly for sidelink communication.

BRIEF SUMMARY OF SOME EXAMPLES

The following presents a summary of one or more aspects of the present disclosure, in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated features of the disclosure, and is intended neither to identify key or critical elements of all aspects of the disclosure nor to delineate the scope of any or all aspects of the disclosure. Its sole purpose is to present some concepts of one or more aspects of the disclosure in a form as a prelude to the more detailed description that is presented later.

In one example, a method for wireless communication at a first wireless communication device is disclosed. The method includes establishing a first sidelink with a second wireless communication device on a first frequency band including a first carrier frequency, establishing, at least in part utilizing the first sidelink, a second sidelink with the second wireless communication device on a second frequency band including a second carrier frequency, and transmitting sidelink control information associated with data to be transmitted from the first wireless communication device to the second wireless communication device on the first sidelink. The method further includes transmitting the data to the second wireless communication device on the second sidelink.

Another example provides a first wireless communication device that includes a processor, a wireless transceiver communicatively coupled to the processor, and a memory communicatively coupled to the processor. The processor and the memory are configured to establish a first sidelink with a second wireless communication device on a first frequency band including a first carrier frequency via the wireless transceiver, establish, at least in part utilizing the first sidelink, a second sidelink with the second wireless communication device on a second frequency band including a second carrier frequency via the wireless transceiver, and transmit sidelink control information (SCI) associated with data to be transmitted from the first wireless communication device to the second wireless communication device via the wireless transceiver. The processor and the memory are further configured to transmit the data to the second wireless communication device on the second sidelink via the wireless transceiver.

Another example provides a method for wireless communication at a first wireless communication device. The method includes establishing a first sidelink with a second wireless communication device on a first frequency band including a first carrier frequency and receiving sidelink control information (SCI) associated with data to be transmitted by the second wireless communication device on the first sidelink. The SCI can include an indicator that the SCI is scheduling the data on resources within a second frequency band including a second carrier frequency.
