Abstract: A method, performed in a wireless device, for obtaining position information of user equipment, UE, in a wireless communication system is described. The method includes transmitting, to a network, an indication comprising beam information defining beams that are suitable to be used for transmitting Positioning Reference Signals, PRS, to the wireless device, receiving, from the network, control signaling comprising PRS scheduling information for upcoming transmission of the PRS in beams, performing measurements on the PRS based on the PRS scheduling information that was received, and providing the measurements to the network.
Abstract: Disclosed are methods for avoiding, detecting, and mitigating message faults. Due to the expected large increase in electromagnetic background energy in in dense 5G and 6G networks, message faults are likely to dramatically increase, along with their costs. To avoid intermittent interference, a user device can monitor the noise level and request that the base station store incoming messages while the noise level is too high. Likewise, if a user device receives a faulted message while the noise level is high, the user device can delay the retransmission until the noise subsides. If the user device has received two faulted messages (a likely scenario in crowded urban/industrial/sporting environments), the user device can merge the two versions while selecting the message elements with the best quality (based on modulation, SNR, stability, and other criteria) and may thereby obtain a corrected message version, without resorting to a third transmission of the message.
