    摘要: An example technique may include: receiving, by a mobile station from a base station, a plurality of copies of a broadcast information including a broadcast control message, wherein a copy of the broadcast information is transmitted via each of a plurality of basis function beams; determining, by the mobile station, a gain and phase value for each copy of at least a subset of the plurality of the received copies of the broadcast control message transmitted via different basis function beams. The technique may also include, for example, determining, by the mobile station, a combined broadcast control message based on at least the subset of the plurality of the received copies of the broadcast control message and the gain and phase value for each copy of at least the subset of the plurality of the received copies of the broadcast control message.

    摘要: An example technique may include controlling receiving a first block of time domain symbols and a second block of time domain symbols, converting the blocks of time domain symbols to the frequency domain to create a first pre-equalized block of frequency domain symbols and a second pre-equalized block of frequency domain symbols, respectively, applying, a linear phase shift to the frequency domain symbols to compensate for a conjugating and time-reversing of corresponding pre-spread domain symbols being performed at a transmitter before spreading of the pre-spread domain symbols, and creating a first equalized block of frequency domain symbols and a second equalized block of frequency domain symbols as a function of the first and second pre-equalized blocks of frequency domain symbols wherein at least one of the first and second pre-equalized blocks of frequency domain symbols has the linear phase shift applied.

    摘要: Systems and techniques for joint transmission cooperative multi-point. A set of n CSI reference signal resources are to be measured by a user device. The n CSI reference signal resources include at least one CSI reference signal resource spanning over at least two transmission points. Channel state information feedback corresponding to each CSI reference signal resource is configured. Upon receiving CSI from the user device, at least one precoder is selected for coherent joint cooperative multipoint transmission based on inter-transmission point phase relationship information. A co-phasing factor is derived from transmitted precoders over a cross-cell CSI reference signal resource, the derivation including transmission of reference signals using first and second precoding vectors on two ports, computation of a third vector using feedback based on the precoded reference signals, and computation of the co-phasing factor based on the first, second, and third vectors.
