    摘要: A user equipment (UE) begins to access a heterogeneous network by obtaining synchronization parameters from system signals transmitted by a weaker one of a number of neighboring cells. After synchronizing with the network, the UE obtains resource scheduling information for the weaker cell. The resource scheduling information indicates at least one resource used by the weaker cell. The UE may then cancel the stronger cells of the neighboring cell. The resource scheduling information allows the UE to identify broadcasted system blocks for the weaker cell from which it may decode and retrieve control information used to complete access to the network.

    摘要: Techniques for reliably transmitting and receiving control information in a wireless network are described. A cell may typically send control information on a control channel and associated data (e.g., system information) on a data channel in the same subframe. This subframe may have strong interference from other cells. For cross-subframe signaling, the cell may transmit the control information in a first subframe and the associated data in a second subframe. The first subframe may be a usable subframe for the cell and may have less interference from other cells. A UE may not know the location of the first subframe and may perform window-based decoding. The UE may decode the control channel in at least one subframe within a decoding window covering the first subframe to obtain the control information. The UE may then decode the data channel in the second subframe based on the control information to obtain the data.

    摘要: Certain aspects of the disclosure provide for the protection of broadcast signals in heterogeneous networks. As described herein, a first set of resources used for downlink transmission in a first cell may overlap with a second set of resources used for broadcast signals in a second cell. The broadcast signals may be protected by allocating a third set of resources for the downlink transmission in the first cell, wherein the third set of resources is based, at least in part, on the overlapping set of resources.

    摘要: Aspects disclosed herein relate to channel and interference estimations in a coordinated multi-point (CoMP) environment. In the disclosed aspects, an eNB may be equipped to signal an identifier indicating a plurality of resource patterns, each associated with a resource pattern group, and each including a first resource element pattern for channel estimation and a second resource element pattern for interference estimation. The UE may be equipped to receive the signaling and perform channel estimation based at least in part on the first resource clement pattern, and interference estimation based at least in part on the second resource pattern generate at least one channel state report based on the channel and interference estimations, and transmit at least one channel state report to an eNB. The eNB may determine one or more resources for use by the UE based on the at least one received channel state report.
