摘要： A wireless communication device receives an indication of timing alignment of a discontinuous reception (DRX) duration, determines a timing alignment for a reception/transmission (RX/TX) switching pattern of the wireless communication device based on the timing alignment of the DRX duration, and performs half-duplex (HD) communication with a radio access node according to the RX/TX switching pattern having the determined timing alignment.

摘要： A network node may identify a location to be allocated for a multicast message within a transmission subframe based on at least information identifying the transmission subframe, and then transmit the multicast message at the identified location in the transmission subframe. A network node may also identify a transmission subframe in which to transmit a multicast message, allocate transmission resources in the transmission subframe for the multicast message, and transmit information indicating a location of the allocated transmission resources in the transmission subframe in a control signal message having a transmission power adjusted based on at least one of information identifying the transmission subframe and a code redundancy version of the multicast message.

摘要： A method and apparatus for beamspace processing in a radio access node are proposed. A channel estimate, which characterizes a radio channel between the antenna elements of an antenna array and a user equipment for a given time and a given frequency, is transformed using multiple distinct sets of spatial orthonormal basis functions to obtain transformed channel estimates. Each one of the distinct sets of spatial orthonormal basis functions defines a respective one of beamspace transformations. Based on measures of quality of beamspace transformation, a set of spatial orthonormal basis functions is selected from the sets of the spatial orthonormal basis functions to satisfy a beamspace reduction criteria for the radio channel. Data streams are encoded, based on a selected transformed channel estimate, into encoded data streams. The encoded data streams are then transmitted through the antenna elements of the antenna array.
