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: 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: Techniques are described that provide for virtual symbol splitting for uplink and/or downlink wireless transmissions. A wireless transmitter, such as a UE or a base station, may identify a pilot signal and a payload to be transmitted in a full symbol. The transmitter may format the pilot signal and the payload into separate sub-symbols that are nested within the first full symbol, with each sub-symbol including an associated sub-symbol cyclic prefix, and the full symbol including a full symbol cyclic prefix.

The guard band signal includes a symbol that is repeated a number of times equal to the multiple. The guard band signal may be generated and transmitted by a transmitting device. The guard band signal may be received and decoded by a receiving device. The guard band signal is interpretable according to a first numerology of the first radio access technology and according to a second numerology of the second radio access technology.

Abstract: Wireless communications systems and methods related to the reduction in a probability of collision for grant-less transmissions from internet of everything (JOE) devices while not increasing search complexity at a base station are disclosed. An IOE device randomly selects a first access resource from a common pool, that the base station searches, to initiate a transmission. If a metric associated with the data transmission is predicted to exceed a threshold, the IOE device also randomly selects a second access resource from a collision reduction pool that the base station does not search. The IOE device notifies the base station, in the data transmission, to switch to the second access resource after a fixed period to the selected second access resource that is included in the data transmission. After the specified period, the base station and the IOE device switch to the second access resource and complete the data transmission.

Abstract: Wireless communication devices are adapted to facilitate non-orthogonal underlay transmissions. In one example, wireless communication devices can receive a wireless transmission via a particular time and frequency resource, where the wireless transmission includes a first signal employing a modulation associated with orthogonal wireless communication, and a second signal employing a modulation associated with non-orthogonal wireless communication. The wireless communication device can decode the first signal and the second signal. In another example, wireless communication devices may transmit a first signal utilizing a first type of modulation associated with non-orthogonal wireless communication, where the first signal is transmitted over at least a portion of a time and frequency resource scheduled for a second signal from a second wireless communication device, the second signal utilizing a second type of modulation associated with orthogonal wireless communication.

Abstract: At times a UE may have a data transmission that needs to extend beyond a resource grant in an ULRB portion of a slot. The UE may receive resource region reservation information from a base station and determine when to extend an UL transmission from the ULRB portion of a slot into the ULCB portion of the slot based resource region reservation information. The resource region reservation information may indicate ULCB resources which are reserved for PUCCH, PRACH, PUSCH, SRS, or other transmissions. The UE may determine to refrain from extending the data transmission into the ULCB when at least a portion of the data transmission would overlap reserved resources as indicated by the resource region reservation information.

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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that may be configured to receive a downlink control message, to determine a beta offset value for transmitting UCI based at least in part on the downlink control message, and to transmit the UCI on an uplink shared channel interleaved with data based on the determined beta offset value. The apparatus may identify the beta offset from a set of values based on the downlink control message. An apparatus may identify resources allocated for PUSCH and may map UCI to the identified resources for PUSCH in a frequency interleaved manner over a bandwidth of the identified resources. The apparatus may map data to the identified resources in a time-first or frequency-first manner, and may transmit a signal comprising UCI and data on the identified resources of the PUSCH in accordance with the mapping.
