    摘要: Techniques are provided for third-party assisted peer-to-peer (P2P) communication. For example, there is provided a method, operable by a network entity, that may involve receiving first information from a first mobile entity, the first information comprising a first message for a second mobile entity. The method may involve receiving second information from the second mobile entity, the second information comprising a second message for the first mobile entity. The method may further involve coding third information based at least in part on the first information and the second information, and sending the third information to the first and second mobile entities. The method may also involve transmitting a control signal that includes processing information for decoding the coded third information to extract the first message or the second message.

    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.

    摘要: Systems and methods facilitating communication of downlink information are provided. In one embodiment, a method can include receiving a signal indicative of a base station enabling or disabling a function, wherein the function is configured to transmit information carried in control channels using selected downlink information; receiving the selected downlink information at one or more locations; and determining a resource allocation of at least one of paging information or system information or unicast data information based, at least, on the selected downlink information. The determining can be performed without decoding control channels corresponding to the selected downlink information in response to receiving a signal indicative of the function being enabled.

    摘要: Certain aspects of the present disclosure propose methods for reporting information such as a maximum power spectral density to a serving access point after receiving overload indicators from one or more neighboring access points. The reported information may be multiplexed with other information (e.g., Channel Quality Indicator (CQI), Precoding Matrix Index (PMI), rank indication (RI) or acknowledgement (ACK)/negative acknowledgment (NACK) message for downlink data channel) before transmission to the serving access point. In addition, the information may be transmitted in a medium access control (MAC) packet data unit (PDU).

    摘要: Efficient apparatus and method for Zadoff-Chu (“Chu”) sequence generation avoids additional processing and hardware complexity of conventional quadratic generating formula followed by Discrete Fourier Transform (DFT) with a reference signal generator that produces both a Zadoff-Chu sequence and its DFT. In the wireless communication system (e.g., Long Term Evolution (LTE) system), Chu sequences are extensively used, especially in the uplink (UL). Because of the single carrier operating mode, transmitting a Chu sequence in principle involves a succession of generating that sequence, performing a DFT operation and then an IFFT operation. Assuming that the sequence length is N, the initial sequence generation requires 2N multiplications and the DFT requires more than N log 2(N) multiplications. Given the frequent processing of Chu sequences, this would represent a complexity burden. The invention makes it possible to perform the sequence generation and DFT steps without any multiplication operation, except for possibly calculating certain initial parameters.
