ABSTRACT:
Techniques for supporting MIMO transmission are described. Users are classified into a first group of users to be scheduled individually for MIMO transmission and a second group of users that can be scheduled together for MIMO transmission. Transmission resources are allocated to the first and second groups, e.g., based upon various criteria such as the number of users in each group, data requirements of the users, total loading for each group, etc. The transmission resources may be hybrid automatic retransmission (HARQ) interlaces, frequency channels, time frequency resources, etc. The resource allocation may be semi-static. The transmission resources allocated to each group are used for data transmission on the downlink and/or uplink for the users in the group. HARQ with blanking may be used for data transmission for the users in the first group. HARQ without blanking may be used for data transmission for the users in the second group.
