Abstract: Techniques and apparatus for rate matching physical downlink shared channel (PDSCH) around zero power (ZP) channel state information reference signal (CSI-RS) resources in slot aggregation scenarios are described. In one technique, an indication that triggers a set of ZP CSI-RS resources is received in a first slot of a plurality of aggregated slots. A rate matching behavior for processing a PDSCH transmission received in the first slot and at least a second slot, subsequent to the first slot, of the plurality of aggregated slots is determined. The PDSCH transmission received in the first slot and at least the second slot is processed in accordance with the rate matching behavior.

Abstract: Disclosed are techniques for generating a positioning beacon sequence suitable for use in a wireless network that utilizes beamformed communication. More particularly, the positioning beacon sequence may be generated based on a first sequence that depends on a link identifier and does not depend on a beam index assigned to a beam used to transmit the positioning beacon in combination with a second sequence that depends on the beam index and does not depend on the link identifier. For example, the first sequence and the second sequence may be XORed to obtain the final beacon sequence, or the first sequence and the second sequence may be modulated and multiplied to obtain the final beacon sequence. Furthermore, in practice, the beacon sequence may be generated using a pseudo-random sequence generator initialized with a seed in which the link identifier and the beam index are treated as separate subcomponents.

Abstract: The present disclosure relates to mitigating collision between reference signals and direct current subcarriers both occupying at least a same resource element of a resource block. Specifically, a UE may at least adjust a DMRS pattern within the resource block based on determining an upcoming occurrence of the collision between the DMRS and the DC subcarrier. Further, a network entity may determine that the UE should transmit the DMRS according to an adjusted DMRS pattern and transmit the adjusted DMRS pattern to the UE on a downlink communication channel.

Abstract: A method, apparatus, and computer-readable medium are provided that improve decoding of downlink data that has been rate matched around aperiodic tracking reference signals, e.g., aperiodic CSI-RS. A UE receives a downlink control channel scheduling a downlink data channel. The downlink control channel may comprise an indication of a zero-power channel state information-reference signal (ZP CSI-RS) configuration from a base station. The UE receives the downlink data channel that is rate matched around CSI-RS resources indicated in the ZP CSI-RS configuration and decodes the downlink data channel based on the indication of the ZP CSI-RS configuration received from the base station.

Abstract: Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.

Abstract: Certain aspects of the present disclosure provide techniques for slot aggregation in new radio (NR) systems. A method of wireless communication by a user equipment (UE) includes receiving radio resource control (RRC) signaling providing a semi-static configuration for transmission and/or reception of a repeated transport block (TB) and/or a different TB in each of a plurality of aggregated slots. The UE transmits or receives the TBs in the plurality of aggregated slots based on the semi-static configuration. Another method is provided in which the UE transmits and/or receives a demodulation reference signal (DMRS) in each of a plurality of aggregated slots, each DMRS associated with a repeated TB or a different TB in the slot. The UE determines, based on received signaling, whether the DMRS use a same precoder or a different precoder and modulates and/or demodulates the TBs in the plurality of aggregated slots based on the determination.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for mapping modulated symbols to physical resources. The mapping described herein may result in both time and frequency diversity. For example, a method for wireless communications may include alternately mapping quadrature amplitude modulated (QAM) symbols of a code block to frequency resources within a scheduling unit of time, wherein the mapping comprises a frequency-first mapping where symbols of the code block are alternately mapped to a first subset of the frequency resources in a first set of orthogonal frequency division multiplexed (OFDM) symbols, then to a second subset of the frequency resources in a second set of OFDM symbols, and transmitting the code block based on the mapping.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications in a wireless network via a radio access technology. The method generally includes determining dimensions of a matrix to be used for performing interleaving of modulated symbols carrying bits, from a plurality of code blocks, for mapping into bundles of resource elements, in an orthogonal frequency division multiplexed (OFDM) system, based, at least in part, on one of a ratio of a code block size to a number of bits to be mapped into each resource element or the number of bits to be mapped into each resource element, performing the interleaving of the modulated symbols, according to the matrix having the determined dimensions, and transmitting the interleaved modulated symbols in the wireless network via the radio access technology. Other aspects, embodiments, and features are also described and claimed.

Abstract: An apparatus and method of wireless communications includes transmitting, by a user equipment (UE), a mid-amble position indication and/or a UE capability information, wherein at least one of the mid-amble position indication or the UE capability information facilitate identification of a mid-amble position within a slot. Additionally, the aspects include receiving, by the UE, a transmission including a transmitted slot having a preamble and a mid-amble, wherein the mid-amble is at the mid-amble position within the slot as determined based at least in part on the at least one of the mid-amble position indication or the UE capability information. For example, the preamble and the mid-amble include pilot signals, such as Demodulation Reference Signals (DMRSs).

Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.
