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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a UE. The apparatus may generate a reference signal using a base sequence obtained from a table, the table including a plurality of base sequences that each have a peak-to-average-power ratio (PAPR) metric below a threshold. Then, the apparatus transmits the reference signal to a base station. The reference signal may be multiplexed with a data transmission.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support aperiodic and cross component carrier PRSs. Generally, the described techniques provide for receiving a dynamic trigger indicating that a UE is to monitor for one or more downlink positioning reference signals (PRSs). The UE may generate a timing measurement for the one or more downlink PRSs, and may transmit a measurement report that indicates the timing measurement to a transmission/reception point. A UE may also transmit a capability indicator, indicating that the UE is capable of maintaining phase coherence for a PRS that spans multiple component carriers, receive control signaling that indicates multiple component carries on which the PRS is phase coherent, generate a timing measurement for the PRS based on the control signaling, and transmit a measurement report that indicates the timing measurement to the transmission/reception point.

Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH transmissions in multi-TRP scenarios. In some cases, if first and second TRPs have little or no coordination, each TRP may take care to avoid transmitting on DMRS resources of the other TRP. In some cases, each TRP may be assigned a different subset of DMRS ports of a port group.

Abstract: Aspects of the disclosure relate to a transmitting device, which may explicitly or implicitly signal the use of continuous precoding for a resource block (RB) cluster. For example, the transmitting device may implicitly indicate that continuous precoding is applied to an RB cluster by dynamically controlling one or more parameters of a transmission over those RBs. Further, when continuous precoding is applied to an RB cluster, the transmitting device may explicitly or implicitly signal the dynamic control over one or more transmission properties, with an aim to maximize the benefits of such continuous precoding. Other aspects, embodiments, and features are also claimed and described.

Abstract: Techniques related to reference signals and reference signal allocations are provided. In some implementations, a method of wireless communication includes receiving, at a user equipment (UE) from an electronic device, an indicator that indicates an allocation of a sounding reference signal (SRS) to multiple disjoint frequency resources of one or more resource bandwidths (BWs). The method further includes transmitting, to the electronic device, the SRS via the multiple disjoint frequency resources in accordance with the allocation of the SRS. Other aspects and features are also claimed and described.

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: Aspects of the present disclosure provide a wireless device that communicates with another wireless device utilizing self-contained subframes. The wireless device communicates with a scheduling entity utilizing a plurality of self-contained subframes that include a first subframe and a second subframe. Each of the self-contained subframes includes an uplink (UL) portion and a downlink (DL) portion. The wireless device further receives DL control information from the scheduling entity in the DL portion of the first subframe, and transmits UL data that includes a plurality of reference signal bursts to the scheduling entity in the UL portion of the first subframe. The plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe.

Abstract: This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE) from a base station, a trigger for aperiodic sounding reference signal (SRS) transmission for a group of component carriers (CCs), and selecting for transmission, by the UE and in response to the trigger, one or more SRS resource sets for each CC of the group of one or more CCs. At least one CC has multiple SRS resource sets configured. The UE transmits, to the base station, an SRS on each CC of the group of CCs based on the selecting. Another method of wireless communication includes transmitting, by a base station to a UE, a trigger for aperiodic SRS transmission for a group of CCs. At least one CC has multiple SRS resource sets configured for the UE. The base station receives, from the UE, one or more SRS on each CC of the group of CCs.
