    摘要: A method for enhancing a sounding reference signal (SRS) in a non-root wireless communication device is disclosed. The method determines that all SRS transmissions for the wireless communication device are to occur in an uplink pilot time slot (UpPTS) portion of a transition subframe. The method also determines whether available uplink bandwidth for the UpPTS portion is greater than available uplink bandwidth for a normal uplink subframe. A current SRS is transmitted using the available uplink bandwidth for UpPTS portion when the available uplink bandwidth for the UpPTS portion is greater than available uplink bandwidth for the normal uplink subframe.

    摘要: Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.

    摘要: Techniques for handling inconsistent control information in a wireless communication system are described. In an aspect, inconsistent control information is handled in different manners for the downlink and uplink. In one design, a user equipment (UE) receives a first grant with first control information for a first data transmission and also receives a second grant with second control information for a second data transmission. The UE determines that the second control information is inconsistent with the first control information, e.g., due to the two grants conveying different transport block sizes. The UE determines whether to retain or discard the second grant based on whether the two grants are for data transmissions on the downlink or uplink. In one design, the UE retains the second grant if the two grants are for data transmissions on the downlink and discards the second grant if the two grants are for data transmissions on the uplink.

    摘要: Techniques for supporting fallback operation in a multi-carrier communication system are described. In one aspect, a UE may determine at least one first downlink control information (DCI) format to monitor on a first carrier. The UE may monitor for the first DCI format(s) on the first carrier to detect DCI sent to the UE. The UE may receive a reconfiguration message related to communication on a plurality of carriers by the UE with cross-carrier signaling, and may determine at least one second DCI format to monitor on the first carrier based on the reconfiguration message. The UE may monitor for the first DCI format(s) and the second DCI format(s) on the first carrier after receiving the reconfiguration message.
