    Abstract: A method is provided including receiving, by a user equipment from a wireless network, an indication of a plurality of contention based transmission occasions and a monitoring window size that the user equipment monitors for feedback for the contention based transmission; determining, by a user equipment of a wireless network, whether an amount of user data can be transmitted on one or more of contention based transmission occasions; performing one or more contention based transmissions during the one or more of the contention based transmission occasions based at least on the determination; and monitoring for feedback for each of the performed contention based transmissions based at least on the monitoring window size, wherein the feedback includes feedback for each contention based transmission in a feedback mapping window.

    Abstract: In accordance with some embodiments, an apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least receive at least one random access preamble from user equipment. The at least one memory and the computer program code can be further configured to, configure at least one backoff indicator. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least transmit the at least one backoff indicator and at least one backoff configuration indicator to the user equipment. The at least one backoff configuration indicator is used to indicate how the at least one backoff indicator is applied.

    Abstract: Various communication systems may benefit from appropriately configured feedback. For example, certain embodiments may benefit from single cell point-to-multipoint feedback methods and mechanisms. A method can include determining by a user equipment, that a data transport block was not received. The method can also include feeding back, by the user equipment, a preamble indicating a measured downlink channel state information responsive to the determination that the data transport block was not received.

    Abstract: Various communication systems may benefit from improved transmissions. For example, a network transmission may benefit from improved throughput and efficiency in non-schedule multiple access communications. A method includes selecting at a user equipment operating in a non-scheduled access scheme at least one of a first codeword or a second codeword based on an amount of data. The data in the non-scheduled access scheme can be spread according to a spreading sequence. The method also includes determining a transport block size for at least one of the first codeword or the second codeword. In addition, the method includes transmitting the data from the user equipment to a network node using at least one of the first codeword or the second codeword.
