    摘要: A wireless communication method includes allocating physical uplink control channel (PUCCH) data in first slot to a first orthogonal cover code (OCC). The method also includes allocating PUCCH data in a second slot of the same subframe to a different orthogonal cover code (OCC). Another method includes mapping PUCCH resources to physical resource blocks based on a user equipment (UE) specific signaling parameter (e.g., a resource index) and a number of symbols in a slot of a subframe.

    摘要: Certain aspects of the present disclosure provide techniques for determining resources for transmission of acknowledgement messages to a user equipment (UE). The techniques involve receiving a plurality of codewords from the UE via an uplink component carrier, and determining at least first and second index pairs identifying resources of a downlink channel to be used for transmitting acknowledgement messages for the received codewords. The first index pair is determined based on a first set of parameters, and the second index pair is determined based on the first set of parameters and a second set of one or more parameters. At least one of the parameters in the second set is a fixed value.

    摘要: Methods and apparatuses are provided that include providing transmit diversity for data channel transmissions. Different precoding vectors can be used over different slots of a given subframes to precode corresponding signals. The precoding vectors, in one example, can be orthogonal. In addition, using the different precoding vectors can be determined based on a user equipment receiving an indicator from a base station receiving the data channel transmissions of whether to use frequency hopping over the slots. Moreover, precoding vectors used to precode data channel transmissions can additionally or alternatively vary across subframes.

    摘要: Methods and apparatuses are provided that include using orthogonal precoding vectors to precode signals for transmission in a given subframe. Transmissions in a first slot of the subframe can be precoded with a first precoding vector, and transmissions in a second slot of the subframe can be precoded with a second precoding vector, which can be orthogonal to the first precoding vector. The precoding vectors can be selected using precoding vector switching or a similar mechanism. Thus, diversity is provided for transmissions within a given subframe to improve reliability of receiving the transmissions. In addition, other precoding vectors can be used to precode signals for transmissions in a subsequent subframe.
