    摘要: Devices and methods are provided for transmit power control in a wireless communication environment. In one embodiment, the method may involve measuring an interference amount over at least one of a sub-band and a full bandwidth. The method may involve assigning a level to the measured interference amount, the level comprising one of an overloaded level and an underloaded level. The method may involve encoding the level as an overload indicator, the overload indicator being conditioned on the sub-band such that the overload indicator includes enhanced layer symbols regarding the level of the measured interference amount. The method may involve conveying the overload indicator to at least one mobile device.

    摘要: In order to cancel any interference due to the second cell signal (e.g., from a non-serving cell) from a signal received at a UE, without receiving additional control information, the UE blindly estimates parameters associated with decoding the second cell signal. This may include determining a metric based on sets of symbols associated with the cell signals in order to determine parameters for the second cell signal, e.g., the transmission mode, modulation format, and/or spatial scheme of the second cell signal. The parameters for the signal may be determined based on a comparison of the metric with a threshold. When a spatial scheme and a modulation format is unknown, the blind estimation may include determining a plurality of constellations of possible transmitted modulated symbols associated with a potential spatial scheme and modulation format combination. Interference cancellation can be performed using the constellations and a corresponding probability weight.

    摘要: In release 8 of the LTE standard (“Rel-8”), a control channel and its associated data channel for downlink may be found in the same subframe. However, decoding of the control channel may be difficult if there is strong interference from different cells (e.g., due to interference from strong/dominant interfering cells). Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). For example, cells may partition subframes to avoid interference. For some embodiments, allocating resources for a downlink data channel on one subframe may come from a PDCCH on a different subframe, which can be referred to as a cross-subframe assignment. Certain aspects of the present disclosure provide subframe-specific search spaces that may be used when there is at least one cross-subframe assignment in a subframe.

    摘要: Certain aspects of the disclosure relate to performing cross-subframe control channel signaling for wireless communications. A method may be provided for signaling downlink control channel resource allocations and/or physical control format indications in a subframe different from the subframe in which a downlink data transmission may be performed. In one aspect, the method may include transmitting PDCCH and/or PCFICH during a first subframe to allocate resources for a PDSCH during a second subframe and transmitting the PDSCH during the second subframe.

    摘要: Systems and methodologies are described that facilitate sending a power control command in a wireless communication environment. A base station can send a power control command to a UE through resource elements reserved for at least one Physical Downlink Control Channel (PDCCH). Thus, the power control command can be punctured into a control channel element (CCE) reserved for the at least one PDCCH. Further, the base station can convey an indicator that specifies the resource elements reserved for the at least one PDCCH used for sending the power control command to the UE. Moreover, the base station can use a structure similar to a conventional (e.g., Release 8, . . . ) PHICH structure for sending the power control command using the resource elements reserved for the at least one PDCCH. For example, the power control command can be spread using one or more Walsh codes assigned to the UE.
