1. A user equipment (UE), comprising:
- a processor circuit;
a configuration component for execution by the processor circuit to establish a connectionless small data transmission (CSDT) mode; and
a communication component for execution by the processor circuit to;
receive a resource reservation message indicating a pattern describing a set of reserved resources for CSDT, the set of reserved resources to comprise respective reserved resources of each of a plurality of radio frames including a first radio frame and a second radio frame, at least a portion of the reserved resources of each of the first and second radio frames reserved for the UE for CSDT;
send a small data item in the CSDT mode using reserved resources of the first radio frame; and
when an acknowledgment message is not received for the small data item, perform a backoff procedure and retransmit the small data item in the CSDT mode using reserved resources of the second radio frame.

Abstract
Various embodiments are generally directed to techniques for connectionless small data transmission. In one embodiment, for example, an apparatus may comprise a processor circuit, a configuration component for execution by the processor circuit to establish a connectionless small data transmission (CSDT) mode, and a communication component for execution by the processor circuit to send a small data preamble, receive a resource allocation message identifying an assigned resource, and send a small data item in the CSDT mode using the assigned resource. Other embodiments are described and claimed.

9. A computer-implemented method, comprising:
-
receiving a resource reservation message indicating a pattern describing a set of reserved resources for connectionless small data transmission (CSDT), the set of reserved resources to comprise respective reserved resources of each of a plurality of radio frames including a first radio frame and a second radio frame, at least a portion of the reserved resources of each of the first and second radio frames reserved for a user equipment (UE) for CSDT; identifying a small data item for transmission using CSDT; transmitting, using CSDT, the small data item using reserved resources of the first radio frame; monitoring a physical hybrid automatic repeat request (ARQ) indicator channel (PHICH) for an acknowledgment of the small data item; and when no acknowledgment of the small data item is received, performing a backoff procedure and retransmitting, using CSDT, the small data item using reserved resources of the second radio frame. - View Dependent Claims (10, 11, 12, 13, 14, 15)
