    摘要: In a method of wireless communication, a UE receives a configuration to receive a CIF for a serving cell of a plurality of serving cells. In addition, the UE monitors a PDCCH on a primary cell of the plurality of serving cells. Said primary cell is different than said serving cell. Furthermore, the UE assumes information received in the PDCCH is for said primary cell when the received information has a common payload size and is in a common search space with a first CCE index in the common search space being equal to a first CCE index in a UE specific search space.

    摘要: Providing a coding scheme for wireless communication downlink reference signals is described herein. By way of example, a dedicated reference signal is mapped to resources of a wireless channel as a function of an identifier (ID) of a cell in which the reference signal is transmitted. The function can be similar to mapping functions employed for common reference signals, or can be distinct from such functions. As one example of the latter, a dedicated reference signal mapping function can be shifted in time or frequency with respect to the common reference signal mapping function. By employing a mapping function based on cell ID, noise caused by concurrent transmission of reference signals can be mitigated in a manner readily determined by terminals in a wireless network.

    摘要: Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.

    摘要: Systems and methodologies are described that facilitate indicating a type of waveform utilized for uplink transmission in a wireless communication environment. An access terminal can select a type of waveform from a set of possible waveform types. Moreover, a reference signal can be generated based upon the selected type of waveform. For instance, a sequence employed to yield the reference signal can be generated and/or chosen as a function of the selected type of waveform. According to another illustration, a tone location and/or a symbol location of the reference signal can be based upon the selected type of waveform. Further, the reference signal can be sent as part of the uplink transmission to the base station from the access terminal. The base station can detect the selected type of waveform utilized by the access terminal for the uplink transmission based upon parameter(s) recognized from the reference signal.

    摘要: Methods and apparatuses are provided that facilitate generating sequences for transmitting reference signals (RS) based at least in part on a cell identifier or other parameters common for a plurality of cells. Where the plurality of cells provide similar joint uplink resources to a device in multi-user multiple-input multiple-output (MIMO), the device can transmit a signal to the plurality of cells over the joint uplink resources. For RSs transmitted according to a sequence generated based on a cell specific identifier or other parameters, the device can utilize a cell identifier, or other parameters, common to the plurality of cells such that the plurality of cells can all decode the RSs. In this regard as well, the plurality of cells can each receive or generate the common cell identifier or other parameters to properly decode the RSs.
