Abstract: Techniques are described for wireless communication. One method for wireless communication includes transmitting, to a user equipment (UE), an indication of a control channel subcarrier spacing to be used by the UE; and transmitting a control message having a subcarrier spacing in accordance with the indication. Another method for wireless communication includes transmitting, to a UE, an indicator channel identifying at least a subcarrier spacing to be used in one or more subsequent control channels. One or more subsequent control channels are then transmitted in accordance with the subcarrier spacing indicated by the indicator channel.

Abstract: A method at a scheduling entity might include determining that interference is present from a neighboring scheduling entity, which implements a second subcarrier spacing that is different from a first subcarrier spacing of the scheduling entity. The scheduling entity might request the neighboring scheduling entity to negotiate a bandwidth group (BWG), where the BWG is a bandwidth occupied by downlink subcarriers within which a transmission parameter is maintained. The method might include negotiating a bandwidth of the bandwidth group and transmitting, if negotiating is successful, downlink data to a scheduled entity served by the scheduling entity according to the negotiated bandwidth. The transmission parameter might be a precoder, rank, modulation order, power inside each BWG, or numerology. The numerology might be scalable and might be a combination of subcarrier spacing and cyclic prefix (CP) overhead. The subcarrier spacing might be scaled while keeping constant the CP overhead as a percentage of a symbol duration.

Abstract: Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.

Abstract: Certain aspects of the present disclosure provide techniques for applying precoding patterns to shared channel transmission repetitions. In one example, a method of transmitting data from a device in a wireless communication network, includes: determining a number of repetitions to transmit data in the wireless communication network; determining a precoding pattern that specifies a precoder to be applied to each repetition of the number of repetitions; and transmitting the data according to the number of repetitions and according to the precoding pattern.

Abstract: A wireless communications system may support a large number of user equipment (UEs) and a base station may transmit resource configuration information to a group of UEs, in which the configuration information identifies the group of UEs. In some cases, the base station may receive a data transmission from a UE of the UE group that the base station cannot decode. The base station may then transmit a group-common feedback signal to the UE group. Once the transmitting UE of the UE group receives the group-common signal, the UE may re-transmit the data to the base station. By sending a group-common feedback signal, the base station may conserve resources, improve reliability and increase successful uplink transmissions from UEs.

Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink channel multiplexing and waveform selection. Uplink channels to be transmitted from one or more user equipment (UEs) to a base station are multiplexed together or separately into an uplink subframe. Each UE is capable of using different waveforms to transmit different channels. Reference signals are communicated according to an RS pattern, which is symmetric across uplink and downlink channels.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may be configured to monitor a first set of decoding candidates within a first search space for receiving a physical downlink control channel message. A base station may identify downlink data for the user equipment and may transmit a signal to the user equipment. The user equipment may receive the signal within the first search space. In some cases, the signal may include a command for activating a second search space. The user equipment may monitor a second set of decoding candidates within the second search space based on receiving the signal. The user equipment communicate, with the base station, based on monitoring the first set of decoding candidates within the first search space and the second set of decoding candidates within the second search space.

Abstract: Systems, devices, and methods associated with interference aware sounding reference signals are provided. A method for wireless communication includes receiving, at a wireless communication device in communication with a first base station, an interfering signal from a second base station (or others); determining, at the wireless communication device, a spatial direction of the interfering signal; and transmitting, with the wireless communication device, a signal to the first base station based on the spatial direction of the interfering signal. Another method includes receiving, at a first base station, a signal from a wireless communication device, the signal based on a spatial direction of an interfering signal received by the wireless communication device from a second base station (or others); transmitting, with the first base station, a downlink communication to the wireless communication device, the downlink communication beamformed in the spatial direction based on the signal received from the wireless communication device.

Abstract: Certain aspects of the present disclosure provide techniques for uplink preemption indication. A method for wireless communication by a user equipment (UE) includes receiving at least one ULPI from a base station (BS) indicating, for each of a plurality of sets of uplink resources, a power level the UE can use for one or more uplink transmissions. The UE can determine one or more power levels indicated by the ULPI for resources allocated for the UE for uplink transmission. The allocated resources may include multiple of the sets of uplink resources. The UE can select the power level to use for uplink transmission using the allocated resources based, at least in part, on the determination. The UE sends or drops the one or more uplink transmissions according to the ULPI. A time duration of the plurality of sets of uplink resources can be longer than a configured ULPI monitoring periodicity.

Abstract: Methods, systems, and devices for increasing the reliability of low latency transmissions are described. For example, multiple control messages and/or multiple data messages may be transmitted for a single transport block. Explicit and/or implicit signaling may be used to support the repetition of control and data transmissions in a low latency environment. For example, explicit signaling may be used to indicate a correspondence between repeated control and/or data messages. Additionally or alternatively, particular configurations may be used to implicitly signal a correspondence between repeated control and/or data messages.
