Communication of user specific control information in a wireless network
A wireless device generates a High Efficiency Signal B (HE-SIG-B) field by Block Convolution Code (BCC) encoding and rate-matching a BCC block of the HE-SIG-B field, generates a Physical Layer Protocol Data Unit (PPDU) including the HE-SIG-B field, and transmits the PPDU. A total number N is a total number of bits of the HE-SIG-B field that precede the BCC block, and is greater than 0. The BCC block has a puncturing pattern depending on the total number N. A wireless device receives a PPDU. The PPDU includes an HE-SIG-B field that includes an encoded BCC block. The wireless device de-rate-matches the encoded BCC block having a puncturing pattern depending on a total number N. The total number N is a total number of decoded bits of the HE-SIG-B field that preceded the BCC block, and the total number N is greater than 0.
1. A method performed by an electronic device, the method comprising:
creating, by the electronic device, an encoded field by Block Convolution Code (BCC) encoding a field including a plurality of BCC blocks;
generating, by the wireless device, a rate-matched field by:
rate-matching, according to a first puncturing pattern, a first BCC block of the encoded field, and
rate-matching, according to a second puncturing pattern different from the first puncturing pattern, a second BCC block of the encoded field,
wherein a code-rate of the first BCC block is equal to a code-rate of the second BCC block; and
transmitting, by the electronic device, the rate-matched field.
2. A method performed by an electronic device, the method comprising:
receiving, by the electronic device, a rate-matched field, the rate matched field including a plurality of Block Convolution Code (BCC) blocks; and
generating, by the electronic device, a de-rate-matched field by:
de-rate-matching a first BCC block of the rate-matched field according to a first puncturing pattern, and
de-rate-matching a second BCC block of the rate-matched field according to a second puncturing pattern different from the first puncturing pattern,
wherein a code-rate of the first BCC block is equal to a code-rate of the second BCC block; and
generating, by the electronic device, a decoded field by decoding the de-rate-matched field.
