    摘要： A radio base station (RBS) provides dynamic rate adaptation for rate-adjustable communication channels used to transmit information to remote mobile stations based on monitoring transmit power information associated with those channels. For a given channel, the RBS tracks an average channel power on a per transmit frame basis and compares the average to first and second rate adjustment thresholds, which comparisons trigger downward or upward rate adjustments. Similar operation also may be based on averaging the power control commands returned by the mobile station, which indicate whether the channel's power as received by the mobile station is or is not sufficient with respect to a desired signal quality. This method thus provides a mechanism for rapid rate adaptation without requiring explicit rate control signaling from the mobile stations.

    摘要： Signaling design for interlaced frequency divisional multiplex (IFDM) demodulation reference signals (DMRS) is discussed in which a dynamic indication is provided to a user equipment (UE) from a serving base station that allows the UE to configure transmission of DMRS according to either a single carrier frequency divisional multiplex (SC-FDM) or IFDM configurations, as indicated by the dynamic indication. The IFDM configuration may be applicable to either regular uplink subframes or within the uplink portion of special subframes. In some aspects, power boosting may be provided for the DMRS in order to equalize transmit power between decimated DMRS transmitted with the data tones. Additional aspects may also provide for different offsets to be used depending on the type of uplink control signal transmitted.

    摘要： Techniques for sending ACK/NACK information in a multi-carrier wireless communication network are disclosed. In one aspect, a plurality of ACK/NACK transmission techniques are selectively employed by a multi-carrier user equipment (UE) to reduce the number of bits of ACK/NACK information to send and/or increase the number of payload bits available for sending the ACK/NACK information. The ACK/NACK transmission techniques may include an orthogonal sequence reduction technique, a channel selection technique, a spatial bundling technique, a carrier bundling technique, and/or a subframe bundling technique. The ACK/NACK transmission techniques may be prioritized based on the number of carriers on which data transmissions are received, a payload size available for carrying ACK/NACK information, and/or other factors. The multi-carrier UE can utilize different ACK/NACK transmission techniques in connection with different subsets of its configured carriers.

    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： Techniques for reporting channel state information (CSI) in a multi-carrier wireless communication system are disclosed. In some examples, a user equipment determines a configuration for reporting CSI for each component carrier (CC) in a plurality of component carriers. For a first subframe, the user equipment determines a priority for transmitting CSI associated with the plurality of CCs based at least in part on the configuration. The user equipment sends, in the first subframe, a CSI report including the prioritized CSI. The CSI report can include CSI for a single CC, or CSI for multiple CCs. For multi-CC reporting of CSI, the user equipment can multiplex CSI reports or CSI elements for the plurality of CCs up to an available payload size.
