Wireless Device, Network Node, and Methods Performed Thereby, for Handling Transmission

A method performed by a wireless device, the method being for handling transmission, the wireless device operating in a wireless communications network, and the method comprising:

• after a first transmission of first data in a first subset of a set of periodic uplink time-frequency resources for uplink communication to a network node, wherein a size of a buffer of the wireless device for the uplink transmission of the first data is smaller than a threshold, and, in the absence of having received an acknowledgement from the network node that the first data has been received,
• selecting a procedure for sending a second transmission to the network node, the procedure being one of:
• i. a Hybrid Automatic Repeat reQuest (HARQ) retransmission,
• ii. an initial transmission comprising a same message to resume communications as a message to resume communications comprised in the first transmission,
• iii. the initial transmission comprising the same message to resume communications and at least one of:
• a Medium Access Control Protocol Data Unit (MAC PDU), an updated MAC PDU, an updated report on a status of the buffer of the wireless device with respect to a report on the status of the buffer of the wireless device comprised in the first transmission, and an updated report on the power of the wireless device with respect to a report on the power of the wireless device comprised in the first transmission, and
• iv. a random access or random access of small data transmission for the transmission of the data, and
• sending the second transmission to the network node, the sending of the second transmission being in a second subset of the set of periodic uplink time-frequency resources, the second subset being a next subset of the first subset.

A method performed by a network node, the method being for handling transmission, the network node operating in a wireless communications network, and the method comprising:

• a. sending a configuration to a wireless device, wherein the wireless device is to perform a selection based on the configuration, wherein the selection is of a procedure for, after a first transmission by the wireless device of first data in a first subset of a set of periodic uplink time-frequency resources for uplink communication to the network node, wherein a size of a buffer of the wireless device for the uplink transmission of the first data is smaller than a threshold, and, in the absence of having received an acknowledgement from the network node that the first data has been received, sending a second transmission to the network node, the procedure being one of:
• i. a Hybrid Automatic Repeat reQuest (HARQ) retransmission,
• ii. an initial transmission comprising a same message to resume communications as a message to resume communications comprised in the first transmission,
• iii. the initial transmission comprising the same message to resume communications and at least one of:
• a Medium Access Control Protocol Data Unit (MAC PDU), an updated MAC PDU, an updated report on a status of the buffer of the wireless device with respect to a report on the status of the buffer of the wireless device comprised in the first transmission, and an updated report on the power of the wireless device with respect to a report on the power of the wireless device comprised in the first transmission, and
• iv. a random access or random access of small data transmission for the transmission of the data.

A wireless device, for handling transmission, the wireless device being configured to operate in a wireless communications network, and the wireless device being further configured to:

• after a first transmission of first data in a first subset of a set of periodic uplink time-frequency resources for uplink communication to a network node, wherein a size of a buffer of the wireless device for the uplink transmission of the first data is configured to be smaller than a threshold, and, in the absence of having received an acknowledgement from the network node that the first data has been received,
• a. select a procedure for sending a second transmission to the network node the procedure being configured to be one of:
• i. a Hybrid Automatic Repeat reQuest, HARQ retransmission,
• ii. an initial transmission configured to comprise a same message to resume communications as a message to resume communications configured to be comprised in the first transmission,
• iii. the initial transmission being configured to comprise the same message to resume communications and at least one of:
• a Medium Access Control Protocol Data Unit, MAC PDU, an updated MAC PDU, an updated report on a status of the buffer of the wireless device with respect to a report on the status of the buffer of the wireless device configured to be comprised in the first transmission, and an updated report on the power of the wireless device with respect to a report on the power of the wireless device configured to be comprised in the first transmission, and
• iv. a random access or random access of small data transmission for the transmission of the data, and
• b. send the second transmission to the network node, the sending of the second transmission being configured to be in a second subset of the set of periodic uplink time-frequency resources, the second subset being configured to be a next subset of the first subset.
