    摘要: Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

    摘要: Methods and apparatus for processing channel quality information (CQI) and scheduling resources subject to cooperative resource allocation based on the CQI are provided. To convey the CQI for protected/unprotected subframes in a single report, a new vector CQI format may be utilized. Two alternatives for CQI processing this vector format and the advantages of each are described. In the first alternative, a single entry from the CQI vector is selected for processing by a downlink scheduler and/or other media access control (MAC) blocks (e.g., a PHICH, DCI power control, and/or PDCCH scheduler). In the second alternative, the selection from the CQI vector is made on a per-subframe basis, and both the subframe and the selected CQI element are processed by the downlink scheduler and/or the other MAC blocks. In this manner, better scheduling decisions may be made using the CQI vector.

    摘要: A method and apparatus are for communication in a wireless network in which a User Equipment (UE) associated with a first evolved Node B (eNB) experiences interference from a second eNB. The method includes negotiating by the first eNB of the wireless network with a second eNB of the wireless network for a partitioning of subband resources on an uplink. A first subset of subband resources is assigned to the first eNB, and a second subset of subband resources is assigned to the second eNB. A method and apparatus are for communication in a wireless network. The method includes decoding a downlink control channel received during a protected downlink subframe to determine an uplink subframe n containing a protected subband for uplink transmission. The method also includes transmitting data during the uplink subframe n on the protected subband.
