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: Certain aspects of the present disclosure provide techniques for scaling transmission power across transmit chains for physical uplink shared channel (PUSCH) transmissions. In some cases, a UE may determine a transmit power budget, receiving signaling indicating how to allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, allocate the transmit power budget across transmit chains for a physical uplink shared channel (PUSCH) transmission, and transmitting the PUSCH using the transmit chains according to the determined transmit power allocation.

Abstract: Aspects of the present disclosure provide techniques for managing unwanted transmissions by a wireless communications device, such as spurious transient transmissions caused by changing a power level of a transmitter. An exemplary method includes determining, based on one or more parameters, an action to reduce an impact of a spurious transmission by the UE, wherein the spurious transmission relates to at least one of changing a transmit power level at the UE or switching one or more radio components at the UE, and taking the determined action to reduce the impact.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine at least one of a downlink path loss value or an uplink path loss value associated with a base station; receive system information, a semi-persistently configured grant via RRC or a dynamic uplink grant via DCI from the base station, wherein the RRC signaling or the dynamic uplink grant identifies a power control value associated with one user or a plurality of users associated with the base station; and determine a transmit power for a data or control transmission based at least in part on at least one of the downlink path loss value or the uplink path loss value and the power control value. Numerous other aspects are provided.

Abstract: The present disclosure relates to mitigating collision between reference signals and direct current subcarriers both occupying at least a same resource element of a resource block. Specifically, a UE may at least adjust a DMRS pattern within the resource block based on determining an upcoming occurrence of the collision between the DMRS and the DC subcarrier. Further, a network entity may determine that the UE should transmit the DMRS according to an adjusted DMRS pattern and transmit the adjusted DMRS pattern to the UE on a downlink communication channel.

Abstract: Various aspects described herein relate to communicating in a wireless network. A resource grant comprising an indicator of whether to transmit a demodulation reference signal (RS) for an uplink control channel or an uplink data channel can be received from a network entity. It can be determined whether to transmit the RS in at least one transmission time interval (TTI) based at least in part on the indicator.

Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation. An exemplary method performed by a base station generally includes determining, based on a location of another base station and information regarding the other base station, that the other base station is likely to experience interference while receiving an uplink transmission due to a downlink transmission by the base station and forming a null in a beam of the downlink transmission in a direction matching the location of the other base station.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to enhanced paging procedures for devices with limited communications resources, such as machine type communication (MTC) devices and enhanced or evolved MTC (eMTC) devices. An example method generally includes determining a set of subframes corresponding to a paging occasion for the UE to receive a paging message from a base station (BS), determining, within the set of subframes, at least one narrowband region for receiving the paging message, and monitoring for the paging message in the at least one narrowband region within the set of subframes.

Abstract: A method, a computer-readable medium, and an apparatus are provided that enable use of a full transmission power for a UE having a first set of coherent antenna ports that is non-coherent to a second set of coherent antenna ports. The apparatus determines a transmission power for a data transmission from the UE to a base station based at least in part on power control signaling from the base station, determines at least one antenna port having non-zero data for transmission, and determines a transmission power split for the at least one antenna port. Then, the apparatus transmits the data transmission from the at least one antenna port, wherein a combined transmission power from the at least one antenna port corresponds to the transmission power determined based at least in part on the power control signaled from the base station.

Abstract: Adjacent channel leakage-power ratio (ACLR) can be reduced at a transmitter of a device. A modulated signal can be mapped into a plurality of tone sets in a frequency domain, wherein the plurality of tone sets include a first, a second, and a third set of tones. The first and the third set of tones can be converted in the frequency domain to a fourth and a fifth set of tones, respectively, in a time domain. A zero padding of one or more symbols associated with the fourth and the fifth set of tones can be performed to output a sixth and a seventh set of tones, respectively. The sixth and the seventh set of tones can be converted to an eighth and a ninth set of tones, respectively, in the frequency domain. The eighth and the ninth set of tones can be processed for transmitting to another wireless device.
