Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit control information using a narrowband common control region that occupies a portion of a system bandwidth. In some cases, data may be multiplexed during the same time period in tones that are not used by the common control region. The base station may transmit control region configuration information to one or more user equipment (UE) devices such as the bandwidth, central frequency, and multiplexing status of the common control region. In some cases, the common control region may be divided into subbands, and different UEs may be assigned to monitor different subbands. Unassigned UEs may monitor a default anchor subband.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method of communication by an apparatus. The method includes selecting one or more resources for transmitting data of a first data stream based on an acyclic graph. The selected resources conform to the acyclic graph comprising data streams at odd levels of the acyclic graph and resources at even levels of the acyclic graph. The acyclic graph includes edges between each level of the acyclic graph. The edges connect the resources allocated to each data stream. The method further includes transmitting the data of the first data stream on the selected one or more resources.

Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support flexible symbol configurations for uplink channels. In one example a method includes performing transmitting first uplink information from a subordinate entity to a scheduling entity in a long burst portion of one or more slots, and transmitting second uplink information from the subordinate entity to the scheduling entity in a combination of long burst and short burst portions of the one or more slots. Each of the one or more slots includes a portion that carries a physical downlink control channel. The second uplink information is transmitted in a physical uplink control channel

Abstract: Wireless communications systems and methods related to performing hybrid grant-free and grant-based uplink (UL) data transmission. A wireless communication device dynamically selects between a grant-free mode and a grant-based mode based on at least a transmission configuration. The wireless communication device sends a first data packet in the grant-free mode, based on the selecting, using a first UL resource. The wireless communication device sends a second data packet in the grant-based mode, based on the selecting, using a second UL resource allocated to the wireless communication device. Other aspects, embodiments, and features are also claimed and described.

Abstract: Mobile originated and terminated data transmissions are discussed. Communication devices such as user equipment (UE) can be dynamically configured by a network to send and receive data. When a UE connects to a new network, the network can determine mobility of the UE and/or the network resource allocation granularity. Based at least on the network's determinations, the UE can be configured such that access data having a comparatively long life span is used and reused for multiple data transmissions. In some scenarios, access data can be refreshed after expiration of a period of time. Refresh time can be equal to expected life span of reusable access data. After UE configuration, the UE performs mobile originated and terminated data transmissions according to the configuration. Other aspects, embodiments, and features are also claimed and described.

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: Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.

Abstract: Aspects of the present disclosure provide for a network assisted grantless data transmission method operable in a wireless communication network. A wireless device may transmit grantless data without requesting a scheduling entity to grant and schedule network resources prior to the grantless data transmission. A scheduling entity determines interference tolerance information of a plurality of uplink channels, wherein the interference tolerance information is configured to individually indicate an availability of each of the plurality of uplink channels for grantless uplink data transmission. The scheduling entity broadcasts the interference tolerance information to one or more subordinate entities or wireless devices.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to receive a plurality of combined signals. Each combined signal may be on a tone of a plurality of tones. The apparatus may be configured to determine a first pilot signal on a first tone of the plurality of tones. The apparatus may be configured to generate an interference-reduced signal for the first tone by canceling the determined first pilot signal from a first combined signal on the first tone.
