Abstract: Wireless communication includes a user equipment that transmits a message to a base station that includes a preamble and a payload corresponding to the preamble in a random access procedure. A parameter is determined based on the preamble, and a de-modulation reference signal (“DMRS”) sequence that is used for transmitting the payload is generated based on the parameter.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal associated with a first radio access technology (RAT) and a second signal associated with a second RAT. The UE may determine that first signal measurements associated with the first signal satisfy a first condition and second signal measurements associated with the second signal satisfy a second condition. The UE may transmit, to a first base station associated with the first RAT, a measurement report that excludes the first signal measurements and the second signal measurements based at least in part on the first condition and the second condition being satisfied. Numerous other aspects are described.

Abstract: A preprocessing system includes a first port, where one end of the first port is coupled to a first switch, and the other end of the first port is suspended, where the first switch has a connecting end configured to couple to a first interface and is configured to connect a filter and the first interface, a second port configured to receive a first signal or a second signal, where the filter is configured to filter the first signal to obtain a first positioning signal and a second positioning signal, provide the first positioning signal for the first switch, and provide the second positioning signal for a second interface of a global navigation satellite system (GNSS) chip to adapt to a plurality of antenna configuration types and to achieve universality.

Abstract: Provided is a method for controlling delivery of a video stream of a live-stream room, and corresponding server and mobile terminal. The method includes steps of: receiving a connection request initiated by an anchor user of the live-stream room from a first terminal and including pre-protocol information outputted by a second terminal; sending, in response to the connection request, a first live video stream uploaded by the first terminal down to the second terminal; and receiving a third live video stream uploaded by the second terminal and formed by combining at least one of a second live video stream and the first live video stream, and delivering the third live video stream to a member user in the live-stream room.

Abstract: A method for preparing TEM sample, comprising the following steps: providing a sample with two pits and a failure region between the two pits, the failure region comprising a semiconductor device; milling the first surface of the failure region, till the cross section of the semiconductor device is exposed; etching the first surface of the failure region; cleaning the sample; milling the second surface of the failure region, till the failure region can be passed by electron beam. A sample can be prepared for a high resolution TEM through above steps. When the sample is observed, it is easy to distinguish the lightly doped drain, source/drain regions from the silicon substrate and observe the pattern and defects in the lightly doped drain, source/drain regions clearly; in addition, it is easy to distinguish the BPSG from the non-doped silicon dioxide in the failure region.
