Claims (8)

  1. 1. An apparatus for communication, comprising means for: receiving a further indication from the reader device that message 3 of the access procedure has not been received at the reader device, wherein the further indication does not comprise a retransmission of message 2 of the access procedure, and Based on the further indication, it is determined that a subsequent retransmission of the message 2 of the access procedure will not be received from the reader device, wherein the apparatus is configured to receive an indication from the reader device that the message 3 of the access procedure has not been received at the reader device in the same message, and a retransmission of the message 2 of the access procedure.
  2. 2. The apparatus of claim 1, wherein the other indication comprises an indication that a subsequent retransmission of the message 2 of the access procedure will not be received from the reader device.
  3. 3. The apparatus according to claim 1 or 2, comprising means for receiving from the reader device in the same message the indication that the message 3 of the access procedure has not been received at the reader device, and the retransmission of the message 2 of the access procedure.
  4. 4. An apparatus for communication comprising at least one processor and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to at least perform: receiving a further indication from the reader device that message 3 of the access procedure has not been received at the reader device, wherein the indication does not comprise a retransmission of message 2 of the access procedure, and Based on the further indication, it is determined that a subsequent retransmission of the message 2 of the access procedure will not be received from the reader device, wherein the apparatus is configured to receive an indication from the reader device that the message 3 of the access procedure has not been received at the reader device in the same message, and a retransmission of the message 2 of the access procedure.
  5. 5. The apparatus of claim 4, wherein the other indication comprises an indication that a subsequent retransmission of the message 2 of the access procedure will not be received from the reader device.
  6. 6. The apparatus of claim 4, wherein the at least one memory stores instructions that, when executed by the at least one processor, further cause the apparatus to perform receiving the indication from the reader device that the message 3 of the access procedure has not been received at the reader device in the same message, and the retransmission of the message 2 of the access procedure.
  7. 7. A method for communication, comprising at an apparatus configured to receive from a reader device, in the same message, an indication that message 3 of an access procedure has not been received at the reader device, and a retransmission of message 2 of the access procedure: Receiving a further indication from the reader device that message 3 of the access procedure has not been received at the reader device, wherein the indication does not comprise a retransmission of message 2 of the access procedure, and Based on the further indication, it is determined that a subsequent retransmission of the message 2 of the access procedure will not be received from the reader device.
  8. 8. A computer program product comprising instructions that, when executed by an apparatus, cause the apparatus to perform operations configured to receive, from a reader device in the same message, an indication that a message 3 of an access procedure has not been received at the reader device, and a retransmission of the message 2 of the access procedure: Receiving a further indication from the reader device that message 3 of the access procedure has not been received at the reader device, wherein the indication does not comprise a retransmission of message 2 of the access procedure, and Based on the further indication, it is determined that a subsequent retransmission of the message 2 of the access procedure will not be received from the reader device.

Description

Apparatus, method and computer program product for communication Technical Field Various embodiments of the present disclosure relate generally to methods, apparatuses and computer program products and, in particular, but not exclusively, relate to message 3 failure indication in AIoT device random access. Background A communication system may be considered to be a facility that enables communication sessions between two or more communication devices or provides network access to communication devices. A mobile or wireless communication network is an example of a communication network. The communication device may be provided with a service by an application server. The mobile or wireless communication network may operate in accordance with standard(s) such as provided by 3GPP (third generation partnership project) or ETSI (european telecommunications standards institute). Examples of mobile or wireless communication networks operating in accordance with 3GPP standards are commonly referred to as 4G (fourth generation) networks, 5G (fifth generation) networks, 5G advanced networks, and 6G networks. Disclosure of Invention Some embodiments of the present disclosure will be described with respect to certain aspects. These aspects are not intended to be indicative of the critical or essential features of the various exemplary embodiments of the disclosure nor is they intended to be limiting in scope. Other features, aspects, and elements will be apparent to those skilled in the art in view of this disclosure. For example, it should be understood that other aspects may be provided by a combination of any two or more of the various aspects described herein. In a first aspect, there is provided a method comprising, at an apparatus configured to receive an indication from a reader device that a message 3 of an access procedure has not been received at the reader device in the same message, and a retransmission of a message 2 of the access procedure, receiving a further indication from the reader device, the further indication being an indication that a message 3 of the access procedure has not been received at the reader device, wherein the indication does not comprise a retransmission of a message 2 of the access procedure, and determining that a subsequent retransmission of a message 2 of the access procedure will not be received from the reader device based on the further indication. The further indication can comprise an indication that a subsequent retransmission of message 2 of the access procedure will not be received from the reader device. The method can include receiving from the reader device in the same message an indication that message 3 of the access procedure has not been received at the reader device, and retransmitting message 2 of the access procedure. The apparatus can be an environmental internet of things AIoT device, the apparatus can include an environmental internet of things AIoT device, or the apparatus can be included in an environmental internet of things AIoT device.
