A method for a UE to perform a MUSIM operation is provided. The method includes connecting to a first network associated with a first USIM; transmitting a request message to the first network, the request message including assistance information to request a time gap for the MUSIM operation; receiving a first time gap configuration from the first network in a case that a type of the time gap requested by the UE is aperiodic, the first time gap configuration indicating a starting SFN and a starting subframe of a first configured time gap; and in a case that the UE receives the first time gap configuration, switching to a second network, while keeping a connection to the first network, during the first configured time gap according to the first time gap configuration, the second network being associated with a second USIM.

Examples described herein relate to an investigator device and a method for determining a condition of an antenna of an access point (AP). At least one investigator device may receive one or more antenna condition test frames transmitted via a plurality of antennas of the AP Further, the at least one investigator device may determine an average received signal strength indicator (RSSI) value corresponding to each of the plurality of antennas based on the one or more antenna condition test frames. A condition of the plurality of antennas of the AP may be determined based on a relative comparison between the average RSSI value corresponding to each of the plurality of antennas of the AP. Moreover, in some examples, the at least one investigator device may send a notification to an administrator of the AP based on the condition of the plurality of antennas.

A test device for performing a bling scan includes a digital blind scan circuit. The blind scan circuit includes digital detectors for multiple cellular technologies that simultaneously perform correlation in a baseband frequency range to detect whether received RF signals include a channel of the technologies. The test device launches, responsive to detecting a channel from the blind scan, a signal analysis or a spectrum analysis application for the channel according to a carrier frequency and a technology identified for the channel by the blind scan.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a reference signal received power (RSRP) associated with a reference signal (RS) broadcast by a network. The UE may further measure a received signal strength indicator (RSSI) using a plurality of resource elements (REs) that do not include the RS and excluding REs that do include the RS. Accordingly, the UE may determine a reference signal received quality (RSRQ) associated with the RS based at least in part on the RSRP and the RSSI. Numerous other aspects are described.

A test device tests conditions associated with a fronthaul in an Open Radio Access Network (O-RAN). The test device can field test an O-RAN radio unit (O-RU) installed at a cell site by emulating an O-RAN distributed unit (O-DU) in the O-RAN connected to the O-RU via the fronthaul of the O-RAN. The testing includes testing connectivity of the O-RU to the fronthaul. The testing includes executing managing plane (M-plane) and synchronization plane (S-plane) messaging to test management session establishment, device setting testing, and master clock synchronization testing. Additionally, optical insertion loss in the fronthaul and frequency and power of signals transmitted from the O-RU can be tested.

One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes determining, at a first node, one or more first accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via an established parent node and with receiving messages from the target destination via the established parent node; determining, based on the one or more first accumulated message success rates, that a search for a different parent node should be performed; identifying a plurality of potential parent nodes; computing, for each potential parent node, one or more second accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via the potential parent node and with receiving messages from the target destination via the potential parent node; and based on the second accumulated message success rates, selecting a new parent node from the plurality of potential parent nodes or maintaining the established parent node

One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes listening, at a first node and across a plurality of listening windows, for one or more messages transmitted by a second node during a first period of time; determining a number of messages received by the first node during the first period of time; computing, based on the number of messages received by the first node, a received message success rate associated with a first connection between the first node and the second node, wherein the received message success rate indicates a probability of successfully receiving, at the first node, messages transmitted by the second node via the first connection; and computing, based on at least one message received during the first period of time, a transmitted message success rate associated with the first connection, wherein the transmitted message success rate indicates a probability of successfully transmitting messages from the first node to the second node via the first connection.
