摘要:
A method of wireless communication includes a random access channel configuration for narrow bandwidth operations within a wider LTE system bandwidth. A first random access channel (RACH) configuration is broadcast for a regular device. A second RACH configuration is broadcast for a narrow bandwidth device. The narrow bandwidth device operates in a narrower bandwidth than the regular device.

Aspects describe communicating grant information in a multicarrier wireless communication system. The grant information can be transmitted to mobile devices that have single carrier capability and/or mobile devices that have multicarrier capability. Grant information can be sent in a legacy control region and/or a non-legacy control region.

In accordance with one or more aspects and corresponding disclosure thereof, various aspects are described in connection with channel quality indicator (CQI) feedback in connection with one or more downlink carriers. An anchor carrier scheme is employed to provide channel quality indicator (CQI) feedback of one or more downlink carriers. An indication is set to identify that a designated uplink carrier is used to convey the CQI feedback. An uplink carrier is selected from a set of uplink carriers as an anchor carrier to convey the CQI feedback. CQI feedback is transmitted for one or more downlink carriers using the designated carrier.
摘要:
Systems and methodologies are described that facilitate indicating feedback parameters for multiple single carrier assignments, multicarrier assignments, and/or the like according to single carrier-frequency division multiple access (SC-FDMA), relaxed SC-FDMA, etc. Feedback in relaxed SC-FDMA can be bundled by a mobile device to conserve power. In addition, a downlink assignment indicator (DAI) can be utilized to detect and indicate lost grants.
摘要:
Systems and methodologies are described that facilitate assigning resources for an anchor carrier and an additional carrier with a grant message. The grant message communicated with an anchor carrier can include resource information a plurality of carriers. Moreover, the systems and methodologies that facilitate identifying control information for an anchor carrier and/or an additional carrier based upon an operating mode, wherein the operating mode is a legacy mode or an extended mode. Based on the operating mode, particular resources associated with control regions are monitored for control information for respective anchor carrier(s) or additional carrier(s).
摘要:
The described aspects include methods and apparatus for communicating control information in a carrier aggregation configuration that uses multiple radio access technologies (RAT). A first resource assignment related to a first carrier corresponding to a first RAT can be received, as well as, a second resource assignment related to a second carrier corresponding to a second RAT. The first carrier and the second carrier are aggregated for communicating data in a wireless network. In addition, resources can be determined for communicating first RAT control data for the first RAT over an uplink carrier based at least in part on the first resource assignment. Second RAT control data can then also be communicated in containers and/or using timing for control data of the first RAT over at least a portion of the resources.
摘要:
Systems, methods, apparatuses, and computer program products are described for power headroom reporting. A mobile device may identify a transmit power associated with each of a number of independently power controlled channels on one or multiple carriers configured for use by the mobile device. The transmit power may relate to one channel that is an uplink control channel, and one or more additional channels that are uplink shared channels. The identified transmit power of one channel (e.g., the uplink control channel) may be a virtual transmit power, while other identified transmit powers may be measured transmit powers for actual transmissions. The identified transmit powers may be added up, and the power headroom available for the mobile device may be calculated using the accumulated transmit powers. The mobile device may transmit a power headroom report to a base station.

摘要:
Certain aspects of the present disclosure provide closed loop and open loop power control techniques for each antenna of the user equipment (UE). The access point may measure the received signals from each antenna of the user equipment, calculate a power adjustment parameter for each antenna of the UE, and transmit the parameters to the UE. The UE may use the adjustment parameters to determine the transmit power value for each antenna. In addition, the UE may measure the path loss for each antenna and update the transmit power per antenna based on the path loss and other parameters.
摘要:
Certain aspects of the present disclosure relate to techniques for controlling transmission power and prioritizing transmission carriers. A method of power distribution for different physical layer channels over one or more carriers in case of power limited user equipment (UE) is proposed. Operation modes of the UE with single and multiple power amplifiers/antennas can be supported.
