Abstract: Both precoded sounding reference signals (SRS) and unprecoded SRS are transmitted from a UE to an eNB. The UE may transmit both in the same subframe using either TDM or FDM. Or the UE may transmit each in different subframes from each other. The eNB uses some combination of the precoded SRS and the unprecoded SRS in scheduling resources for the UE. The eNB may also provide instruction to the UE for PUSCH precoding for data transmission. The eNB may signal the UE to use the same precoding as for the precoded SRS. The eNB may instead signal the UE to use different precoding by including the precoding information or delta information between the precoding used for the precoded SRS and the selected precoding for the PUSCH data.

Abstract: NB wireless communication involves numerous challenges. A limited frequency dimension may need to be shared by multiple users. At times, large data transmissions, including multiple TBs of data may be transmitted using NB communication, and it may be important that each TB be successfully received by the users. The apparatus may transmit data comprising a plurality of TBs in a narrow band communications system, including repeating a transmission of the plurality of TBs, using any of a number of repetition patterns. The apparatus may use error correction encoding across multiple TBs. The transmission may be a single cell transmission or a multi-cell transmission.

Abstract: The apparatus enables pilot signals, whether single tone or multiple tone, that achieve a very low PAPR. After receiving an allocation for multiple tones, the apparatus determines a pilot signal for transmission. The apparatus may select tones from the allocation for transmission of a pilot signal based on a pilot pattern. The pilot pattern may comprise a tone sequence that identifies a sequences of tones, wherein each tone in the tone sequence of identifies one tone of multiple tones for transmission of a pilot signal during a given pilot symbol period. The pilot signal may also comprise a signal sequence. The apparatus may generate a set of multi-tone modulated pilot sequences, select a pilot sequence based on a cross-correlation property, and transmit a pilot signal using multiple tones of the allocation using the selected pilot sequence.
