Abstract
Increasing a number of orthogonal time-domain transmission opportunities in a Proximity Services (ProSe) traffic generation period can reduce over-air congestion and collision in long term evolution (LTE) communications. Resource configurations can be adjusted, including providing a new physical layer numerology, reducing transmission time (TTI) interval duration, providing a smaller sidelink control information period, configuring logical sidelink control periods and/or multiplexing of control and data transmissions.
Claims8
A system for sidelink resource configuration comprising:
- an enhanced node B (eNB) wireless interface, the interface configured with a first resource allocation mode having a first transmission time interval (TTI) and a resource block configuration;
- a sidelink wireless interface, the interface configured with a second resource allocation mode, wherein a second TTI of the second resource allocation mode is less than a TTI of the first resource allocation mode, wherein the second resource allocation mode uses the second TTI to reduce buffering to achieve a 100 milliseconds latency, and wherein fewer symbols of a resource block are used in the TTI of the second resource allocation mode than the first resource allocation mode;
- a processor coupled to the eNB wireless interface and sidelink wireless interface, the processor configured to:
- switch to the second resource allocation mode from the first resource allocation mode;
- and
- transmit a message to a sidelink capable device using the second resource allocation mode and the second TTI.
