Title:
PRECODER RESOURCE GROUP ALLOCATION METHODS FOR MIMO COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2018/205921
Kind Code:
A1
Abstract:
Aspects of the present disclosure disclose various methods tor grouping network resources into precoder resource groups (PRGs) for precoding in MIMO communication. A user equipment (UE) may select a common precoder that may not be restricted to a codebook for preceding the resources in the same PRG. These resource grouping methods provide the UE with the flexibility to select a precoder that is well suited to the channel or bandwidth. Moreover, the base station may reduce downlink signaling because it does not need to signal the precoder choice to the UE. In some examples, the base station may receive PRG based channel state information feedback that facilitates DL preceding. Other aspects, embodiments, and features are also claimed and described.
