1. A method for hybrid automatic repeat request (HARQ) communications in a station (STA), the method comprising:
receiving, at the STA, a first multi-user (MU) transmission including a first HARQ transmission, a preamble including information indicating that the first MU transmission includes the first HARQ transmission, and a first set of HARQ Process Identifiers (IDs) associated with the first HARQ transmission, the first set of HARQ Process IDs including a first subset of HARQ Process IDs for the STA;
determining, at the STA, a portion of the first HARQ transmission associated with the STA;
transmitting, by the STA, a response message after receiving the first MU transmission, indicating at least a reception status of the portion of the first HARQ transmission at the STA; and
receiving, at the STA, a second MU transmission including a second HARQ transmission and a second set of HARQ Process IDs associated with the second HARQ transmission,
wherein:
the second HARQ transmission is different from the first HARQ transmission,
the second set of HARQ Process IDs includes a second subset of HARQ Process IDs for the STA, and
the second subset of HARQ Process IDs is based on at least the reception status of the portion of the first HARQ transmission.
