Abstract: A technique may include transmitting, by a user device in a proximity-based services wireless network via a first time-frequency resource identified by a first logical time index within N logical time resources and a first logical frequency index in the range from 0 to M−1, a first occurrence of a signal for the user device during a transmission period; determining a time index adjustment associated with the first logical frequency index; determining, by the user device, a second logical time index of a second time-frequency resource for transmitting from the user device a second occurrence of the signal within the transmission period, the second logical time index being determined based on the first logical time index and the time index adjustment associated with the first logical frequency index; and transmitting, by the user device via the second time-frequency resource, a second occurrence of the signal during the transmission period.

Abstract: Various communication systems may benefit from appropriate synchronization signal design. For example, third generation partnership project (3GPP) long term evolution advanced (LTE-A) releases 12 and 13 (Rel 12/13) may benefit from such design for device to device (D2D) communications. In particular, synchronization signals may be designed to benefit proximity services (ProSe)/D2D discovery and communication. A method can include transmitting a cellular synchronization signal on a first resource. The method can also include transmitting a device to device synchronization signal on a second resource. The first resource can be different from the second resource. The cellular synchronization signal and the device to device synchronization signal can share a same base sequence.

Abstract: 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.

Abstract: A method includes receiving, at a user equipment, a signal including cell-specific reference signals from a number of cells. Cell-specific reference signal(s) are measured from one of the cells to determine measured result(s). The user equipment, based on the measured result(s) meeting first criteria, performs interference cancelation to cancel the cell-specific reference signal(s) corresponding to the one cell from the signal. The user equipment performs the measuring and the performing the interference cancelation for additional ones of the cells until second criteria are met. The user equipment uses measured cell-specific reference signals having their interference canceled to reduce an effect of interference from corresponding cells on communications between the user equipment and a base station. A base station may store cell search information that can be sent to the user equipment to help the user equipment perform the previous method. Apparatus, systems, computer programs, and program products are also disclosed.

Abstract: A method includes receiving a two-bit information stream comprising first and second bits and performing precoding using the two-bit information stream to determine multiple output signals. The precoding is performed to create a finite multiple of states for the output signals. The output signals comprise a first output signal based on a version of the first input bit and on a version of a second input bit, a second output signal based on a delayed version of the first input bit and the version of the second input bit, and a third output signal based on the version of first input bit and a delayed version of the second input bit. The method includes performing pulse shaping of each of the output signals to create pulse-shaped signals, combining the pulse-shaped signals to create a transmission waveform, and outputting the transmission waveform. Apparatus, computer programs, and computer program products are disclosed.
