Abstract: Methods, systems, and devices for wireless communications are described for configuration aspects of a tracking reference signal in New Radio. A base station may select a first burst duration and a second burst duration for a tracking reference signal (TRS) burst, the first burst duration being different from the second burst duration, and may transmit configuration information indicating the first burst duration and the second burst duration to a user equipment (UE). The base station may transmit a first TRS burst having the first burst duration and a second TRS burst having the second burst duration. The UE may detect the first TRS burst having the first burst duration and the second TRS burst having the second burst duration based at least in part on the configuration information, and perform resource tracking based at least in part on the detected first TRS burst and the second TRS burst.

Abstract: Methods, systems, and devices for wireless communications are described that identify a minimum gap between a control channel transmission on a first component carrier (CC) that triggers a measurement report and an associated reference signal transmission on a second CC. The minimum gap may be based on a resource associated with a control channel transmission and a resource associated with the reference signal transmission. The first CC and the second CC have different numerologies and the minimum gap may be identified in terms of a number of OFDM symbols of the second CC that carries the reference signal transmission. The minimum gap also may be identified based on a location of the control channel transmission within a slot of the first CC. In cases where beam switching is used, the minimum gap may be further based at least in part on a beam switch time for performing the beam switching.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a method for managing SRS transmission in a bandwidth part may include identifying one or more bandwidth parts of a component carrier of a cell to be allocated to a user equipment (UE). The method may also include identifying a sounding reference signal (SRS) bandwidth configuration for each of the one or more bandwidth parts. The method may further include transmitting the SRS bandwidth configuration to the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, multiple timing advances (TAs) may be configured for non-coherent joint transmission (NCJT) with respective transmit receive points (TRPs). For example, a NCJT mode may have multiple TAs semi-statically configured for the UE to follow for each TRP. In some cases, a TA index corresponding to a TA for a TRP may be added as a field to a sounding reference signal (SRS) resource definition (e.g., SRS resource configuration). Additionally or alternatively, the TA index may be determined from an SRS index transmitted by the TRP, where the TA index corresponds to a TA for uplink information in a physical uplink shared channel. Additionally or alternatively, the TA index may be included as a field in a physical uplink control channel (PUCCH) definition to indicate a TA for a corresponding PUCCH that the UE transmits to the TRP.

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: Various aspects described herein relate to techniques for multi-cluster uplink transmissions in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method comprises receiving, by a user equipment (UE), information of one or more sounding reference signal (SRS) patterns, generating, by the UE, one or more rate matching parameters based on the information, and transmitting, by the UE, an uplink signal based on the generated one or more rate matching parameters.

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.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: Methods, systems, and devices for wireless communications are described. A method may include receiving, from a base station and while being outside of a radio resource control (RRC) connected state, an indication of a length of downlink symbols used to transmit a physical downlink shared channel (PDSCH) that carries broadcast information, and decoding the PDSCH based on the indication. Another method may include receiving, from a base station, a PDSCH that carries broadcast information over a plurality of downlink symbols and while being outside of an RRC connected state, perform a first blind decoding of the PDSCH over a first set of the plurality of downlink symbols, and perform a second blind decoding of the PDSCH during a second set of the plurality of downlink symbols, the second set being different in length than the first set.
