Abstract: Aspects of the present disclosure provide techniques for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one channel of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.

Abstract: A UE may be configured for half-duplex communications. An access point may configure half-duplex UEs for efficient resource utilization using two of more different half-duplex configurations that include different timing for channels in different directions. A UE may determine a half-duplex configuration for use in communicating with the access point, each slot of the half-duplex configuration including at least a PDCCH on a downlink frequency and an uplink short burst on an uplink frequency, and each slot associated with a HARQ timeline. The UE may determine a direction for a slot. The UE may transmit or receive according to the direction for the slot and the half-duplex configuration.

Abstract: A user equipment (UE) may perform a random access procedure to synchronize with a network for uplink and/or downlink communication. The UE may transmit a first type of random access transmission that includes transmitting a preamble or a second type of random access transmission that includes transmitting a preamble and a random access message. The second type may result in reduced delay but may have lesser SNR tolerance than the first type. In some aspects, the UE may determine whether to transmit the first type or the second type, and may transmit the first type or the second type in a random access channel portion of a slot. The random access channel portion of the slot may be occupied by portions of either the first type of random access transmission or the second type of random access transmission, thereby enabling flexible utilization of multiple types of random access procedure.

Abstract: Aspects described herein relate to communicating feedback in wireless communications. A user equipment (UE) can receive, in a downlink portion of a slot, data communications from a base station, where the data communications comprise multiple code blocks received in one or more downlink symbols. The UE can generate one or more feedback bits to provide feedback for the multiple code blocks. The UE can transmit, to the base station and in an uplink portion of the slot, an indication of the one or more feedback bits

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a resource spread multiple access scheme is enabled, wherein the bit and/or symbol level resource spreading happens in time and/or frequency domain through bits or symbol level repetition and spreading. Furthermore, the UE may process bits of codewords and modulated symbols using a set of spreading sequences and a set of scrambling sequences. The UE may transmit the modulated symbols with a discrete-Fourier-transform (DFT)-spread (DFT-s) waveform based at least in part on processing the modulated symbols using the set of spreading sequences and the set of scrambling sequences. Numerous other aspects are provided.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A first message can be transmitted, in an inactive or idle state, a on a physical random access channel, where the first message includes a random access preamble. A second message can be received on a downlink channel in response to the first message, where the second message includes a temporary cell radio network temporary identifier and an uplink grant for the user equipment. A request can be transmitted on an uplink channel based on the uplink grant. A common search space of a downlink control channel can be monitored, such as for an acknowledgement message or a negative acknowledgement message corresponding to the request and identifiable based on the temporary cell radio network temporary identifier.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a base station includes identifying time resources and frequency resources for narrowband communication in a plurality of subframes, identifying a plurality of user equipment (UE) devices, allocating a first portion of the time resources and the frequency resources to an uplink (UL) channel to carry UL control information, and allocating resources of the UL channel to the identified UE devices. A method for wireless communication at a UE device includes identifying time resources and frequency resources for narrowband communication in a plurality of subframes, receiving an indication of at least a first portion of the time resources and the frequency resources allocated to a UL channel to carry UL control information for the UE device, and transmitting one or both of downlink acknowledgements (ACKs) and downlink non-acknowledgements (NAKs) on the UL channel.
