Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control information that identifies criteria to use for determining a delivery status of a protocol data unit (PDU) set that includes multiple PDUs. The PDU set may be associated with an application layer of the UE. Accordingly, the UE may receive at least a portion of the PDU set, and may determine the delivery status of the PDU set based on the received portion of the PDU set and the criteria identified by the control information. The delivery status of the PDU set may refer to whether the PDU set was successfully delivered to the UE. The delivery status of the PDU set may be based on a quantity of bits or PDUs in the received portion of the PDU set, a threshold quantity of bits or PDUs, or a combination thereof.

Abstract: Techniques are provide for calibrating device timelines for use in passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first device at a first time, receiving a second positioning reference signal from a second device at a second time, receiving a timeline difference value associated with the first device and the second device, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the timeline difference value.

Abstract: Disclosed are systems, methods, and non-transitory media for providing signaling consideration for wireless positioning with disjoint bandwidth segments. For instance, one or more indications of a preferred bandwidth configuration can be transmitted by a user equipment. Based on the one or more indications, the user equipment can receive a positioning configuration that indicates disjoint bandwidth segments containing a positioning reference signal based on the preferred bandwidth configuration. In response, the user equipment can then determine one or more positioning measurements based on the positioning reference signal in the disjoint bandwidth segments.

Abstract: In an embodiment, a serving BS of a UE may transmit a PDCCH communication to the UE. The PDCCH communication triggers a partial RACH procedure, whereby a RACH transmission is performed. In some designs, the RACH transmission is for positioning, and positioning measurements are performed at the serving BS and (optionally) at one or more non-serving BSs. In some designs, measurement data based on the positioning measurements are conveyed to a position estimation entity (e.g., LMF), which performs a positioning estimate of the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving cell, an uplink positioning reference signal (UL-PRS) resource configuration, the UL-PRS resource configuration comprising a plurality of N resource elements (REs) staggered in frequency across a plurality of M consecutive symbols of a resource block (RB) such that the plurality of N REs spans a plurality of N consecutive subcarriers of the RB, receives, from the serving cell, an indication of a PRS symbol cancelation group to be used for uplink cancelation, the PRS symbol cancelation group identifying a set of the plurality of M consecutive symbols that is expected to be canceled for uplink transmission, and cancels transmission of UL-PRS on one or more of the set of L symbols identified by the PRS symbol cancelation group.

Abstract: A example method of determining a positioning signal measurement includes: sending, from a user equipment to a network entity, a processing-capability message indicating a processing capability of the user equipment for processing an aggregated positioning reference signal, where the processing-capability message corresponds to one or more assistance-data types; obtaining, at the user equipment, the aggregated positioning reference signal; and processing, at the user equipment, the aggregated positioning reference signal based on assistance data to determine the positioning signal measurement, the assistance data including the one or more assistance-data types.

Abstract: The disclosure is directed to prioritizing call announce response in a broadcast/multicast communication system. An embodiment establishes a first priority for response based on assigning each user equipment (UE) a first random delay for response to a first call announce, responds to the first call announce using the first random delay, and determines a second priority for response to a subsequent call announce based on an elapsed time that each UE is present in a multicast area.

Abstract: An access network (AN) receives a call announcement message for transmission to an access terminal (AT). The AN initiates, in response to the received call announcement message, a physical-layer synchronization procedure for at least one channel between the AN and the AT, the physical-layer synchronization procedure associated with a transition of the access terminal to a dedicated channel state. The AN performs the initiation by sending a message to the AT. In response to the message, the AT monitors a downlink channel for receipt of the call announcement message. The AN then transmits the call announcement message on the downlink channel to the access terminal, and the AT receives the call announcement message due to the monitoring. The call announcement message is transmitted either (i) before the physical layer synchronization procedure completes or (ii) before a transmission of a reconfiguration complete message indicating completion of dedicated channel state transition.
Abstract translation: 接入网（AN）接收用于传输到接入终端（AT）的呼叫通知消息。 AN响应于所接收的呼叫通知消息，针对AN和AT之间的至少一个信道发起物理层同步过程，与接入终端转换到专用信道状态相关联的物理层同步过程 。 AN通过向AT发送消息来执行启动。 响应于该消息，AT监视下行链路信道以接收呼叫通知消息。 然后，AN在下行链路信道上发送呼叫通知消息给接入终端，并且AT由于监视而接收呼叫通知消息。 在（i）物理层同步过程完成之前或（ii）发送指示完成专用信道状态转换的重配置完成消息之前，发送呼叫通知消息。

Abstract: A user equipment (UE) transmits reference signals for positioning while in Idle or Inactive state. While in a connected state, the UE is pre-configured with Sounding Reference Signal (SRS) resource configuration including at least one of timing adjustment (TA) and an uplink (UL) transmission spatial filter. The UE transmits positioning SRS while in Idle or Inactive mode based on the pre-configuration. The TA and UL transmission spatial filter may be updated by a serving base station using control signals or a paging message received by the UE while in in Idle or Inactive mode. The validity of the TA and UL transmission spatial filter may be monitored using expiration timers or a relative position change threshold. The reference signals transmitted may be based on a UE may Physical Random Access Channel (PRACH), which is insensitive to TA changes. A long sequence PRACH may be used for improved positioning accuracy.
