Abstract: The subject technology provides for block acknowledgment requests and block acknowledgment frames that can be used in conjunction with multicast transmissions that include multiple concurrent streams. Thus, the subject technology reduces the overhead associated with multicast transmissions that include multiple concurrent streams by aggregating the acknowledgments across multiple streams into a block acknowledgment, thereby increasing the effective throughput of such transmissions and overall network efficiency.

Abstract: Some embodiments enable improved packet error rate (PER), signal to noise ratio (SNR), channel capacity, aggregated throughput, and communication range in wireless communication systems. For example, an electronic device includes a buffer that stores a first descrambled bit estimate sequence. The electronic device further includes an encoder that receives a descrambling sequence and generates an encoded descrambling sequence and a multiplier circuit that receives a bit estimate sequence and the encoded descrambling sequence and generates a second descrambled bit estimate sequence. The electronic device also includes an adder circuit that combines the first descrambled bit estimate sequence and the second descrambled bit estimate sequence and a decoder that decodes the combined descrambled bit estimate sequence.
