Methods for retransmission for improved handling of vulnerable symbols

A method for wireless communications by a first wireless communication device, comprising:

• receiving a set of code blocks (CBs) of a transport block (TB) transmitted from a second wireless communication device blindly via multiple transmissions, such that the first wireless communication device does not require to transmit a response to the second wireless communication device regarding status of decoding of a previous transmission before a next transmission of the CBs in the multiple transmissions;
• determining a permutation order used to transmit the set of CBs in the multiple transmissions;
• and
• processing the set of CB s according to the permutation order, wherein the permutation order depends, at least in part, on a position of vulnerable resources among resources used for the transmissions, wherein the vulnerable resources comprise resources that are vulnerable to potential loss at the first wireless communication device, wherein the permutation order depends, at least in part, on a number of CBs in the set, wherein a number of possible permutations is a factorial of the number of the CBs.

A first wireless communication device, comprising:

• a memory;
• and
• a processor coupled to the memory, the processor being configured to:
• obtain a set of code blocks (CBs) of a transport block (TB) to be transmitted to a second wireless communication device;
• and
• transmit the set of CBs to the second wireless communication device blindly in multiple transmissions, such that the first wireless communication device does not require to receive a response from the second wireless communication device regarding status of decoding of a previous transmission before a next transmission of the CBs in the multiple transmissions, wherein an order of the CBs for each transmission is determined by a permutation order of that transmission, wherein the permutation order depends, at least in part, on a position of vulnerable resources among resources used for the transmissions, wherein the vulnerable resources comprise resources that are vulnerable to potential loss at the second wireless communication device, wherein the permutation order depends, at least in part, on a number of CBs in the set, wherein a number of possible permutations is a factorial of the number of the CBs.
