Methods and devices for scheduling

A method (100) performed in a communication device enabled for communication with a network node, the method comprising:

• receiving, from the network node, a configuration message relating to semi-persistent scheduling, the configuration message comprising an information element indicating a periodicity of the semi-persistent scheduling, wherein the information element has a value within a range of values in which range at least one value corresponds to the periodicity of the semi-persistent scheduling equal to;
• every 1 subframe, every 2 subframes, every 3 subframes, every 4 subframes, every 5 subframes, every 6 subframes, every 7 subframes, every 8 subframes or every 9 subframes,
• performing semi-persistent transmission to the network node in accordance with the semi-persistent scheduling as configured by the configuration message, and
• upon receiving, from the network node, an acknowledgment or a negative acknowledgment relating to a hybrid automatic repeat request, one of which indicates to the communication device to stop a retransmission and continue with the semi-persistent transmission as configured, and the other one of which indicates to the communication device to perform the retransmission and skip a coming semi-persistent transmission, stopping the retransmission and continue with the semi-persistent transmission as configured, or performing the retransmission and skipping the coming semi-persistent transmission.

A communication device enabled for communication with a network node, the communication device comprising a processor and memory, the memory containing instructions executable by the processor, which when executed by the processor, cause the communication device to perform operations to:

• receive, from the network node, a configuration message relating to semi-persistent scheduling, the configuration message comprising an information element indicating a periodicity of the semi-persistent scheduling, wherein the information element has a value within a range of values in which range at least one value corresponds to the periodicity of the semi-persistent scheduling equal to;
• every 1 subframe, every 2 subframes, every 3 subframes, every 4 subframes, every 5 subframes, every 6 subframes, every 7 subframes, every 8 subframes or every 9 subframes,
• perform semi-persistent transmission to the network node in accordance with the semi-persistent scheduling as configured by the configuration message, and
• upon receiving, from the network node, an acknowledgment or a negative acknowledgment relating to a hybrid automatic repeat request, one of which indicates to the communication device to stop a retransmission and continue with the semi-persistent transmission as configured, and the other one of which indicates to the communication device to perform the retransmission and skip a coming semi-persistent transmission, stop the retransmission and continue with the semi-persistent transmission as configured, or perform the retransmission and skip the coming semi-persistent transmission.

A non-transitory computer readable storage medium containing instructions, which when executed by a processor in a communication device enabled for communication with a network node, cause the communication device to perform operations comprising:

• receiving, from the network node, a configuration message relating to semi-persistent scheduling, the configuration message comprising an information element indicating a periodicity of the semi-persistent scheduling, wherein the information element has a value within a range of values in which range at least one value corresponds to the periodicity of the semi-persistent scheduling equal to;
• every 1 subframe, every 2 subframes, every 3 subframes, every 4 subframes, every 5 subframes, every 6 subframes, every 7 subframes, every 8 subframes or every 9 subframes, and
• performing semi-persistent transmission to the network node in accordance with the semi-persistent scheduling as configured by the configuration message, and
• upon receiving, from the network node, an acknowledgment or a negative acknowledgment relating to a hybrid automatic repeat request, one of which indicates to the communication device to stop a retransmission and continue with the semi-persistent transmission as configured, and the other one of which indicates to the communication device to perform the retransmission and skip a coming semi-persistent transmission, stopping the retransmission and continue with the semi-persistent transmission as configured, or performing the retransmission and skipping the coming semi-persistent transmission.
