摘要： A wireless communication system implementing Carrier Aggregation (CA) allows activation and deactivation of certain component carriers. Transmit power on an uplink component carrier being reactivated may be controlled by predetermining appropriate power control parameters to be used upon reactivation. The predetermined power control parameters may depend on a last known power control state of the deactivated component carrier or may be reset to apply an initial low power state.

摘要： Methods, apparatuses, and computer program products are disclosed for facilitating a radio link failure determination. A wireless terminal is configured to monitor a control channel quality of a control signal over at least one control carrier. A radio link failure determination is then made based on the control channel quality of the at least one control carrier. In other embodiments, rather than basing the radio link failure determination solely on the set of control carriers, the wireless terminal is configured to monitor a control channel quality over at least one additional carrier, not included in the set of control carriers, in response to a link loss detected over each of the set of control carriers. For such embodiments, the radio link failure determination is then made based on the control channel quality of the additional carrier(s).

摘要： Systems and methodologies are described herein that facilitate various techniques for enhanced downlink assignment index (DAI) signaling in a multi-carrier wireless communication system. As described herein, DAI and/or other indicator signaling transmitted on a first carrier can be configured to carry information relating to a number of downlink transmission assignments applied to at least a second carrier, which in some cases can be disparate from the first carrier. To these ends, described herein are techniques for cross-carrier DAI signaling, multiple DAI signaling, aggregate DAI signaling, and other similar techniques. As additionally described herein, DAI signaling can be related to downlink control transmissions and/or downlink data transmissions in connection with respective techniques that can be applied to the DAI signaling.

A multi-carrier communication between a wireless terminal and a base station is facilitated by a first carrier having a first control region size and a second carrier having a second control region size. Embodiments are disclosed in which control region sizes are ascertained from a control signal, wherein the control is generated by either scrambling an aspect of the control signal based on the second control region size, or relating the second control region size with the first control region size. Other disclosed embodiments for ascertaining control region sizes include a reverse interleaver embodiment, wherein a set of modulation symbols is mapped beginning from a last data symbol and ending with a first available data symbol.

摘要： Systems and methodologies are described that facilitate employing fractional frequency reuse within carriers in a multicarrier heterogeneous wireless communication environment. Each carrier can be divided into a plurality of frequency reuse sets. Moreover, each of the frequency reuse sets from each carrier can be categorized as being for one of unrestricted reuse or restricted reuse. Further, a downlink transmission can be scheduled upon resources of at least a first subset of frequency reuse sets from a first carrier bandwidth and a second subset of frequency reuse sets from a second carrier bandwidth. For example, the resources can be scheduled based upon a power class of a base station, categorizations of the frequency reuse set (e.g., unrestricted reuse versus restricted reuse, . . . ), and/or received feedback related to downlink channel conditions.

摘要： Systems and methodologies are described that facilitate selecting an uplink carrier for random access within a wireless environment having multiple carriers. Selection of an uplink carrier for random access can be randomly selected from a set of available uplink carriers. Additionally, the uplink carrier for random access can be selected based upon which uplink carrier is paired with an anchor carrier. Further, the uplink carrier for random access can be identified based upon a bandwidth related to the user equipment (UE). Reference signals can also be employed in order to identify an uplink carrier to perform random access.
