Abstract: A user equipment (UE) may map a demodulation reference signal (DMRS) sequence to a first symbol in a set of resource blocks (RBs) of an uplink long burst, and the first symbol may occur at the beginning of the uplink long burst. The DMRS sequence may be “front-loaded” in the uplink long burst. The DMRS sequence may be dependent upon RB locations. When the DMRS sequence is mapped to the beginning of an uplink long burst, uplink control information (UCI) may be mapped in a physical uplink shared channel (PUSCH). A UE may map UCI in a PUSCH after the DMRS sequence is mapped to the beginning of the uplink long burst. When the base station receives an uplink long burst including the front-loaded DMRS and the UCI mapped in the PUSCH, the base station may identify the DMRS for channel estimation/interference cancelation of the UCI carried on the PUSCH.

Abstract: Techniques are described that provide for waveform selection for uplink (UL) and/or downlink (DL) wireless transmissions based on one or more factors associated with the wireless transmission, a transmitter that is to transmit the wireless transmission, or combinations thereof. UL and DL transmissions may use one of a number of different waveforms, such as single-carrier waveforms that use a single carrier for information transmission of a wireless channel, and multi-carrier waveforms that use multiple carriers at different frequencies to transmit some of the bits on each channel. Multi-carrier transmission waveforms or single-carrier waveforms may be selected for wireless transmissions based on a bandwidth allocated for the transmissions, a capability of a transmitter that is to transmit the transmissions, or combinations thereof.

Abstract: Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

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 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.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for physical uplink control channel (PUCCH) resource allocation. In certain aspects, a method for use by a user equipment (UE) for transmitting one or more uplink control information (UCI) bits in PUCCH includes determining resources allocated for providing one or more UCI bits based at least on a type of service associated with the UE and sending, to a base station, a PUCCH with the one or more UCI bits using the allocated resources.

Abstract: A user equipment (UE) may map a demodulation reference signal (DMRS) sequence to a first symbol in a set of resource blocks (RBs) of an uplink long burst, and the first symbol may occur at the beginning of the uplink long burst. The DMRS sequence may be “front-loaded” in the uplink long burst. The DMRS sequence may be dependent upon RB locations. When the DMRS sequence is mapped to the beginning of an uplink long burst, uplink control information (UCI) may be mapped in a physical uplink shared channel (PUSCH). A UE may map UCI in a PUSCH after the DMRS sequence is mapped to the beginning of the uplink long burst. When the base station receives an uplink long burst including the front-loaded DMRS and the UCI mapped in the PUSCH, the base station may identify the DMRS for channel estimation/interference cancelation of the UCI carried on the PUSCH.

Abstract: A first apparatus may determine a demodulation reference signal (DMRS) sequence based on a mother sequence, map the DMRS sequence to at least a first symbol of a set of resource blocks (RBs) in a transmission, and send a DMRS including the mapped DMRS sequence in the at least one symbol of the set of RBs. A second apparatus may receive information associated with resource allocation, determine a granularity based on the information associated with resource allocation, determine resource allocation based at least in part on the granularity, and receive a signal carried on resources corresponding to the resource allocation.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method for wireless communication. The method includes determining at least one RS pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein at least a portion of the at least one RS pattern is the same for the uplink channel and the downlink channel. The method further includes transmitting the reference signal using the determined RS pattern.
