System and Method for User Equipment Cooperation

摘要

User equipment (UE) cooperation can be improved by relaying partial soft information to target UEs. More specifically, a cooperating UE may relay a subset of log-likelihood ratios (LLRs) to the target UE. The subset of LLRs may correspond to fewer than all resource blocks of the original transmission. This may allow UE cooperation to be effective when the cooperating UE was only able to decode a portion of the original transmission. This may also allow fewer network resources (e.g., bandwidth, etc.) to be used when the target UE does not need all of the soft information to decode the original transmission. Multiple cooperating UEs can provide different subsets of LLRs, and the subsets may or may not overlap with one another.

1. A method for user equipment (UE) cooperation, the method comprising:
receiving, by a cooperating UE from a communications controller, a first message transmitted over a plurality of resource blocks (RBs); determining a plurality of log-likelihood ratios (LLRs) in accordance with the plurality of RBs; selecting a first subset of LLRs from the plurality of LLRs, wherein the first subset of LLRs corresponds to fewer than all RBs in the plurality of RBs; and transmitting, by the cooperating UE, the first subset of LLRs to a target UE.
