Method and apparatus for controlling small data transmission on the uplink
First Claim
1. A user equipment (UE) comprising physical layer circuitry to:
- transmit first data on a logical uplink channel, the logical uplink channel having been assigned for use by machine-type communications (MTC) applications for transmission of MTC application data;
receive transmission time restriction information, responsive to the transmitting, that indicates time periods during which the UE is permitted to transmit additional MTC data on the logical uplink channel; and
refrain from transmitting additional MTC data in a time period on the logical uplink channel based on the transmission time restriction information, wherein the transmission time restriction information is received in a radio resource control (RRC) signal from an evolved Node B (eNodeB) in accordance with a standard of the 3rd Generation Partnership Project (3GPP) family of standards, the RRC signal including an information element (IE) to identify a Data Radio Bearer (DRB) and the logical uplink channel for which the transmission time restriction applies, and the RRC signal further including a transmission time restriction IE;
wherein the transmission time restriction IE includes a subframe restriction bitmap for indicating subframes for which the UE is permitted to transmit on the logical uplink channel, andwherein the UE includes a first application with a first priority level and a second application with a second priority level, lower than the first priority level, the refraining includes refraining from transmitting data of the second application, and the UE is further configured to, subsequent to receiving transmission time restriction IE, transmit data for the first application on another logical uplink channel separate from the logical uplink channel in a time period on which the UE refrains from transmitting data for the second application.

Abstract
Apparatuses and methods for control of uplink transmission by a user equipment (UE) using machine-type communications (MTC) applications are described herein. The UE may transmit first data on a logical uplink channel. The logical uplink channel may have been assigned for use by machine-type communications (MTC) applications. The UE may receive transmission time restriction information, responsive to the transmitting, that indicates time periods during which the UE is permitted to transmit additional data on the logical uplink channel. The UE may refrain from transmitting additional data in a time period on the logical uplink channel based on the transmission time restriction information.

7. An evolved NodeB (eNodeB) comprising:
-
a transceiver arranged to receive a transmission on an uplink connection from a user equipment (UE); and a processor arranged to; determine that the UE is a machine-type communications (MTC) UE and that the transmission is for a low-priority application wherein the determining is based on an amount of data in the transmission and on a logical channel on which the transmission was transmitted, wherein a low priority MTC communication is received on a first logical channel and a high priority MTC communication is received on a second logical channel different from the first logical channel; and based on the determining, configure a radio resource control (RRC) configuration message for transmission to the UE, the RRC configuration message including an information element (IE) including information identifying a Data Radio Bearer (DRB) and the logical uplink channel for which the transmission time restriction applies, and the RRC message further including a transmission time restriction IE indicating uplink subframes for which the UE is restricted from transmitting; wherein the transceiver is further arranged to receive additional MTC communications from the UE in a time period based on the transmission time restriction IE and wherein the high priority MTC communication is received on the second logical channel in a time period for which the UE refrains from transmitting low priority MTC communications on the first logical channel responsive to the transmission time restriction IE. - View Dependent Claims (8, 9, 10)
