Determining a position of a wireless device
It is presented a method for determining a position of a wireless device within a single radio cell served by a plurality of remote radio heads. The method is performed in a position determination node and comprises the steps of: receiving a measured power signature comprising at least two, in time separated, power measurement values of a downlink signal, the measured power signature originating from the wireless device; comparing the measured power signature with a set of reference power signatures, wherein each one of the plurality of remote radio heads is associated with a reference power signature and the reference power signatures differ for at least two of the plurality of remote radio heads; and determining a position in that the wireless device is in the vicinity of one of the at least one remote radio head whose reference power signature best matches the measured power signature.
Scheduling request based beam failure recovery
A wireless device transmits a first scheduling request (SR) based on a buffer status reporting procedure. A second SR is triggered in response to initiating a beam failure recovery. The second SR is transmitted via an uplink control channel resource configured for the second SR. A first downlink control information is received via a downlink control channel, as a response to the second SR. Based on receiving the first downlink control information: the first SR is keep pending, and the second SR is cancelled for the beam failure recovery.

Beam switch and beam failure recovery
Methods, systems, and devices for wireless communications are described. One method may include receiving a beam switch message prior to initiating a physical random access channel (PRACH) procedure, monitoring for a response from a base station using a candidate beam during a random access response window, identifying a beam switch event occurring within the random access response window based on beam switch timing information indicated in the beam switch message, and performing a beam switch procedure based on an absence of a response from the base station during a portion of the random access response window and prior to the beam switch event.

Power Control with Multiple Panels in a Radio System
A wireless device receives one or more messages comprising configuration parameters. The configuration parameters indicate pathloss reference signals (RSs) for PUSCH pathloss estimation for transmissions via first and second panels. A medium access control control element (MAC CE) is received. The MAC CE indicates first pathloss RSs of the plurality of pathloss RSs for the first panel. The MAC CE indicates second pathloss RSs of the plurality of pathloss RSs for the second panel. A downlink control information (DCI) is received. The DCI indicates a first pathloss RS. The DCI indicates a second pathloss RS. The wireless device transmits, via the first panel, a first uplink transport block with a first uplink transmission power determined based on the first pathloss RS. The wireless device transmits, via the second panel, a second uplink transport block with a second uplink transmission power determined based on the second pathloss RS.
METHOD FOR DETERMINING TRANSMIT POWER FOR PERFORMING UPLINK TRANSMISSION IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR
Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.
Wireless communication system, communication method and portable transceiver device
A wireless communication system, a communication method, and a portable transceiver device are provided. The wireless communication system includes a server, a plurality of gateway devices and user-end portable transceivers that are interconnected by a wireless WAN protocol, e.g. LoRa. Each portable transceiver connects a user device via a near-end wireless communication protocol that allows the user device to connect with the server via a gateway device. After the user device sends a message through the portable transceiver, the server discovers another portable transceiver and another gateway device according to a destination address. Thereby, the message can be transmitted via this connection, or a direct voice communication can be performed via a communication channel over this connection. The communication system therefore provides a communication service under the wireless WAN protocol that is an alternative to traditional mobile communications.
