Abstract: The disclosure relates in some aspects to a scalable transmission time interval (ITO and hybrid automatic repeat request (HARQ) design. The TTI is scalable to, for example, achieve latency and/or efficiency tradeoffs for different types of traffic (e.g., mission critical traffic versus traffic with more relaxed latency requirements). In the event a longer TTI is employed, various techniques are disclosed for ensuring a fast turn-around HARQ, thereby maintaining a high level of communication performance.

Abstract: A wireless entity, such as a user equipment (UE) or transmission reception point (TRP), receives and processes aggregated positioning reference signals (PRS) to increase the effective PRS bandwidth, thereby increasing positioning accuracy, such as time of arrival measurements. An aggregated PRS includes one or more PRS components that are transmitted from a same transmitting entity. Each PRS component may be, e.g., a separate PRS resource associated with a contiguous frequency-domain bandwidth or may be, e.g., a plurality of frequency-domain bandwidths spanned by a single PRS resource. PRS components of an aggregated PRS that are unpunctured, e.g., do not collide with higher priority signals, are aligned in time domain, and are configured with common constraints are processed jointly assuming that the PRS components are transmitted from a same antenna port, thereby increasing the effective PRS bandwidth.

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: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal to the base station, which characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. The base station may form the beam to the UE based on the uplink channel information obtained from the SRS. As the downlink channel changes the base station needs updated information to maintain its beamforming, meaning it needs a new SRS. Transmission of the SRS takes resources; to minimize this, the UE or the base station can determine a period during which the downlink channel will predictably remain coherent and set up a schedule for sending SRS. Alternatively, the UE or the base station can determine on demand that the channel is losing coherence and initiate an on demand SRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: The present disclosure provides techniques for performing bit-level interleaving for orthogonal frequency-divisional multiplexing (OFDM) symbols across a plurality of code blocks. In some aspects, a transmitting device may dynamically switch between bit-level interleaving and tone-level interleaving for each OFDM symbol based on factors such as number of bits that are carried in each tone, size of each code block, the processing time requirements of the transmitting device and/or the receiving device, or the transmitting device preference.
