摘要： Systems and methodologies are described that facilitate precoding signals transmitted over downlink control channels to provide transmit diversity. A dedicated reference signal (DRS) related to a wireless device can additionally be precoded such that the wireless device can determine a precoder or related parameters based at least in part on performing a channel estimate for the precoded DRS signal. The wireless device can utilize the determined precoder or related parameters to decode precoded signals received over downlink control channel resources. Additionally or alternatively, an access point can signal a sequence of precoders to the wireless device. The access point can cycle through the sequence of precoders to precode signals for transmission over downlink control channel resources, and the wireless device can decode the signals based at least in part on similarly cycling through the precoders for received signals.

摘要： Methods and apparatus for providing cross-cell signaling and/or coordination for interference mitigation in wireless communication networks are described. In one aspect, a UE associated with a serving eNB may receive control signaling from another non-serving eNB in a different cell. The control signaling may be consistent with a characteristic of the serving eNB and associated cell. In another aspect, multiple eNBs may coordinate transmission of DL resources to minimize collisions of control signaling resources.

摘要： Systems and methodologies are described that facilitate controlling interference in a heterogeneous wireless communication environment. A Physical Broadcast Channel (PBCH) transmission from an interfering base station can be punctured based upon a puncturing pattern as a function of a cell identifier (ID) and a transmit time. Puncturing can be effectuated by applying power control. Thus, a punctured symbol or subframe can have a reduced transmit power or a transmit power set to zero. Further, the puncturing pattern can be defined on a subframe basis or on a symbol basis.

摘要： Providing for modified rate-matching of modulated data to convey mobile network system information is described herein. By way of example, a rate-matching state, such as a data offset, can be introduced into a coded data stream that is modulated to resources of a wireless signal. The state can further be correlated to a state of the network system, such as transmit antenna configuration. Terminals receiving the wireless signal can analyze the signal to identify the rate-matching state and obtain the correlated network system state. Components of the terminal can then be configured according to the particular network system state, resulting in improving access point detection, and in some cases improved channel throughput and reliability.
