Systems, methods, and devices for enhancing spectral efficiency with network-assisted advanced receivers
First Claim
1. User equipment (UE) configured to communicate with an evolved universal terrestrial radio access network (eUTRAN), the UE comprising:
- a transceiver; and
a processor coupled to the transceiver, the processor configured to;
receive an indication from at least one of an interfering eUTRAN Node B (eNB) and a serving eNB of whether the interfering eNB is transmitting transmission parameters;
receive a broadcast message comprising indications of transmission parameters for one or more UEs communicating with the interfering eNB;
receive a signal including a transmission from the serving eNB, wherein the transmission comprises a physical downlink shared channel (PDSCH) from the serving eNB; and
cancel PDSCH from the interfering eNB from the signal based on the transmission parameters,wherein the indications of the transmission parameter are also signaled to the one or more UEs semi-statically and dynamically by the interfering eNB, andwherein the indication of whether the interfering eNB is transmitting transmission parameters is received from a physical broadcast channel (PBCH), from the interfering eNB or the serving eNB, that includes a master information block having a bit that indicates whether the interfering eNB is transmitting transmission parameters, a PDSCH from the interfering eNB that includes a system information block having a bit that indicates whether the interfering eNB is transmitting transmission parameters, or the PDSCH from the serving eNB that includes a system information block having a bit that indicates whether the interfering eNB is transmitting transmission parameters.

Abstract
Systems and methods for enhancing spectral efficiency are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The UE may be configured to cancel interference from an interfering eNB. The interfering eNB may provide transmission parameters to the UE. The interfering eNB may transmit a compact message indicative of the transmission parameters to the UE. The compact message may be a broadcast message. Some transmission parameters may be sent to the UE using higher layer signaling. The UE may be able to use the transmission parameters to cancel interference from the interfering eNB. In some embodiments, the interfering and/or serving eNB may indicate to the UE whether the transmission parameters are being broadcast so the UE does not search for them unnecessarily.
