Abstract: A user equipment (UE) may transmit a control channel and a data channel using contiguous resource allocations of a portion of a slot. The control channel may be associated with control channel power spectral density (PSD) and the data channel may be associated with a data channel PSD. When a difference between the control channel PSD and the data channel PSD exceeds a maximum delta value, the UE may experience degraded performance as a result of tonal interference and/or the like. In some aspects, the UE may determine a control channel transmit power for the control channel and a data channel transmit power for the data channel. The control channel transmit power and the data channel transmit power may be determined such that the maximum delta value is not exceeded and that a threshold relating to a link budget is satisfied, thereby ensuring that performance is not degraded.

Abstract: Aspects of the disclosure relate to multiple-input multiple-output (MIMO) signals, and the determination of a precoding matrix for configuring the MIMO signals. An uplink traffic channel may be configured utilizing orthogonal frequency division multiplexing (OFDM) waveform. Determination of the precoding matrix may be based at least in part on an estimate of the uplink carrier, where the uplink carrier estimate is based at least in part on a downlink reference signal, exploiting channel reciprocity in a time division duplex (TDD) carrier. Determination of the precoding matrix may further be based at least in part on a cross-correlation matrix Rnn or a whitening matrix determined by a scheduling entity. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure provide techniques and apparatus for multicast/broadcast for enhanced machine type communications (eMTC) and/or narrowband internet-of-things (NB-IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which can be a low cost device such as an eMTC UE or NB-IoT device. The method generally includes determining at least one narrowband region of a wideband region for receiving at least one of: multicast information or broadcast information in at least one subframe; and receiving the at least one of: the multicast information or the broadcast information in the determined at least one narrowband region in the at least one subframe.

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.

Abstract: Methods, systems, and devices for wireless communication are described to estimate interference for concurrent uplink and downlink communications based on an indication of one or more one or more characteristics of an interfering uplink signal communicated between a base station and a second user equipment (UE). The base station or the second UE may transmit, to a first UE, an indication of one or more characteristics of an uplink signal, such as a baseband of the uplink signal or one or more parameters of the uplink signal. The first UE may use the characteristic(s) of the uplink signal to estimate the baseband of the uplink signal and cancel interference associated with the uplink signal. For example, the first UE may use the baseband signal to estimate the interference and may subtract the estimated interference from a downlink signal received at the first UE.
