    摘要: A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

    摘要: Certain aspects of the present disclosure relate to a method for uplink wireless communications. In one aspect, a diversity scheme may be selectively and adaptively applied to an uplink transmission based on a determination of whether the uplink transmission comprises one or more orphan symbols. According to an aspect, the determination is made based on whether a sounding reference signal is received in the uplink subframe and whether the uplink subframe is configured with a normal or extended cyclic prefix.

    摘要: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a PUCCH, the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a PUSCH, the UE may determine a number of resource elements based on its CC configuration.

    摘要: Wireless uplink communication is disclosed which includes dividing information bits into first and second sets of information bits. The first set of information bits is encoded into a first set of coded bits, while the second set of information bits is encoded into a second set of coded bits. The first and second sets of coded bits are rate matched into a defined number of bits generating first and second sets of rate-matched coded bits. The first and second sets of rate-matched coded bits are interleaved using various interleaving methods to generate an interleaved set of coded bits.

    摘要: Certain aspects of the present disclosure relate to techniques for indicating downlink assignments to a user equipment (UE). According to certain aspects, the techniques generally involve generating a downlink assignment index (DAI) indicating a number of assigned downlink transmissions for a user equipment (UE) configured to communicate using multiple component carriers and transmitting a physical downlink control channel (PDCCH) containing the DAI to the user equipment (UE) in a frequency division duplexing (FDD) subframe in which uplink and downlink transmissions may take place at the same time on different carrier frequencies.
