Abstract
There is provided methods and apparatuses for small data transmissions in telecommunication network. Specifically, there is provided effective and substantially optimized methods and apparatuses for transmission of downlink data after uplink data transmissions in order that the complete small data transmission process is substantially optimized when used in conjunction with small uplink data transmission optimization techniques.
Claims31
A method for small data transmission between a user equipment (UE) and a network node, comprising:
- transmitting, by the UE, uplink data to the network node;
- and
- receiving, by the UE, first downlink control information (DCI), wherein the first DCI includes an acknowledgement of the uplink data transmission and a DCI identifier (ID).
A user equipment (UE) for small data transmission, the UE comprising:
- a network interface for receiving and transmitting data;
- a processor;
- and
- a non-transient memory for storing instructions that when executed by the processor cause the UE to:
- transmit uplink data to the network node;
- and
- receive first downlink control information (DCI), wherein the first DCI includes an acknowledgement of the uplink data transmission and an DCI identifier (ID).
A method for small data transmission between a user equipment (UE) and a network node, comprising:
- receiving, by the network node, uplink data from the UE;
- and
- transmitting, by the network node, first downlink control information (DCI), wherein the first DCI includes an acknowledgement of the uplink data transmission and a DCI identifier (ID).
A network node for small data transmission, the network node comprising:
- a network interface for receiving and transmitting data;
- a processor;
- and
- a non-transient memory for storing instructions that when executed by the processor cause the network node to:
- receive uplink data from the UE;
- and
- transmit first downlink control information (DCI), wherein the first DCI includes an acknowledgement of the uplink data transmission and a DCI identifier (ID).
A method of reconfiguring a preconfigured radio network temporary identifier (PC-RNTI), comprising:
- transmitting, by a network node, a downlink control information (DCI) to a user equipment (UE), wherein the DCI includes a downlink grant and the PC-RNTI;
- and
- transmitting, by the network node, a radio resource control (RRC) message with a cell radio network temporary identifier (C-RNTI) to the UE.
A network node for reconfiguring a preconfigured radio network temporary identifier (PC-RNTI), the network node comprising:
- a network interface for receiving and transmitting data;
- a processor;
- and
- a non-transient memory for storing instructions that when executed by the processor cause the network node to:
- transmit a downlink control information (DCI) to a UE, wherein the DCI includes a downlink grant and the PC-RNTI;
- and
- transmit a radio resource control (RRC) message with a cell radio network temporary identifier (C-RNTI) to the UE.
