First Claim
Patent Images
1. A method at a transmitter for transmission of a transport block, the method comprising:
- appending a cyclic redundancy check to the transport block;
selecting a grant-free transmission resource unit;
encoding, using physical layer rate-less coding, the transport block to generate an encoded transport block; and
transmitting the encoded transport block to a receiver over the grant-free transmission resource unit.

Abstract
Rate-less multiple access schemes for wireless networks uses physical layer, rate-less codes to enable grant-free, contention-based, random access and grant-based, contention-free, non-orthogonal multiple access in uplink or downlink channels.

9. An apparatus for transmission of a transport block, the apparatus comprising:
-
an encoder configured to; append a cyclic redundancy check to the transport block; select a grant-free transmission resource unit; and encode, using physical layer rate-less coding, the transport block, to generate an encoded transport block; and a transmitter configured to transmit the encoded transport block to a receiver over the grant-free transmission resource unit. - View Dependent Claims (10, 11, 12)

13. A method comprising:
-
receiving, at a receiver, signals on a transmission resource unit; storing the received signals; rate-less decoding the received signals to obtain a transport block, the transport block being associated with a scrambled cyclic redundancy check; descrambling, using an identifier associated with a transmitter of the transport block, the scrambled cyclic redundancy check to yield an unscrambled cyclic redundancy check; and transmitting, to the transmitter of the transport block, a positive acknowledgement. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. An apparatus comprising:
-
a receiver configured to receive signals on a transmission resource unit; a decoder configured to; store the received signals; decode, in a rate-less manner, the received signals to obtain a transport block, the transport block being associated with a scrambled cyclic redundancy check; and descramble, using an identifier associated with a transmitter of the transport block, the scrambled cyclic redundancy check to yield an unscrambled cyclic redundancy check; and a transmitter configured to transmit, to a transmitter of the transport block, a positive acknowledgement. - View Dependent Claims (23, 24, 25, 26, 27)
