Abstract: Disclosed are techniques for performing positioning operations. In an aspect, a user equipment (UE) receives a downlink physical channel from a base station, the downlink physical channel received via one or more slots of one or more subframes of one or more radio frames, the downlink physical channel carrying user data and/or control information from the base station to the UE, receives, from the base station, an indication that the base station will transmit reference signals for positioning on the downlink physical channel, and performs a positioning measurement of a reference signal received on the downlink physical channel.

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine to block puncture or to block shorten a set of transmitted bits of an adjusted fractally enhanced kernel polar code for a communication of an incremental redundancy (IR)-hybrid automatic repeat request (HARQ) process based at least in part on a code rate associated with the communication of the IR-HARQ process. The wireless communication device may generate the adjusted fractally enhanced kernel polar code for the communication based at least in part on determining to block puncture or to block shorten the set of transmitted bits. The wireless communication device may transmit the communication using the adjusted fractally enhanced kernel polar code. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) time domain bundling and multiple codeword transmission and processing in new radio (NR) systems. A method by a transmitting device includes transmitting multiple codewords to a receiving device in a first period, each of the multiple codewords transmitted using a different set of one or more DMRS ports. The transmitting device determines to retransmit one or more of the multiple codewords and, for each of the multiple codewords to be retransmitted, the set of DMRS ports for retransmission of the codeword. The determination is based, at least in part, on whether DMRS time domain bundling is configured. The transmitting device retransmits the one or more codewords in a second period based on the determination. The receiving device determines the DMRS ports used and processes the retransmitted codewords based on the determination.

Abstract: A transmitter, such as a base station, identifies a potential collision between a first set of resources configured for a CORESET for a receiver and a second set of resources configured for a PT-RS for the receiver. The apparatus may determine whether colliding resources in the CORESET are configured/used for a control transmission or a data transmission. The apparatus punctures the PT-RS based on whether the colliding resources in the CORESET are configured/used for the control transmission (e.g., PDCCH). For example, the apparatus may puncture the PT-RS only for resource blocks of the CORESET colliding with the control transmission without puncturing the PT-RS over an entire set of the colliding resources configured for the CORESET. A receiver may similarly identify potential collisions and determine whether PT-RS will be punctured based on whether the colliding resources in the CORESET are configured/used for a control transmission or a data transmission.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a communication that includes downlink control information (DCI), wherein a size of the DCI affects a cyclic redundancy check (CRC) value associated with the communication; and determine the DCI or the size of the DCI based at least in part on the CRC value. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract: The present disclosure describes various examples of a method, an apparatus, and a computer readable medium for multi-state discontinuous reception (DRX) in wireless communications. For example, one of the methods described may include identifying, by a user equipment (UE), at least two states in connected mode, determining, by the UE, one or more triggers for transitioning between the at least two states, and transitioning, by the UE, from a first state of the at least two states to a second state of the at least two states in response to a determination of the one or more triggers. In an aspect, the transitioning comprises transitioning between cross-slot scheduling and same-slot scheduling, or between a narrow bandwidth and a wide bandwidth, or between a larger periodicity and a smaller periodicity for monitoring.

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.
