A wireless device transmits a first scheduling request (SR) in response to initiating a beam failure recovery procedure. A second SR for a buffer status reporting procedure is transmitted. A downlink control information comprising an uplink grant is received via a downlink control channel while the first SR and the second SR are pending. Based on the reception of the downlink control information: the second SR for the buffer status reporting procedure is cancelled, and the first SR for the beam failure recovery procedure is kept pending.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink packet duplication configuration that indicates a set of configured carriers and a number of copies of an uplink packet to transmit. In some examples, the UE may receive the uplink packet duplication configuration from a base station. The UE may select a subset of the set of configured carriers based on a selection criterion and the number of copies of the uplink packet to transmit, and transmit an uplink packet transmission that includes the copy of the uplink packet on each carrier of the subset of the set of configured carriers based on the uplink packet duplication configuration.

A method for obtaining uplink calibration values in a terminal of a wireless communication system is provided, in order to enable a Base Station (BS) having a number of antennas to determine a respective hardware chain value for each antenna of the number of antennas, said method comprising calculating, by the terminal, an uplink calibration value for each antenna on the basis of a downlink channel estimate value for each antenna and a normalization value obtained from said downlink channel estimate values, and sending transmitting, by the terminal, the calculated uplink calibration value for each antenna to the BS. A corresponding terminal for a wireless communication system, adapted to obtain uplink calibration values, is also provided.

A method for setting Wi-Fi roaming is provided. The method includes the following. Monitor an operation of connecting a terminal device to a first access point (AP). Obtain a first received signal strength indication (RSSI) of a signal of a wireless network received by the terminal device after the terminal device is connected to the first AP. Determine whether an RSSI adjustment value is greater than a preset RSSI lower limit, where the RSSI adjustment value is a difference between the first RSSI and a preset RSSI weight. The preset RSSI lower limit is set to be a roaming threshold in response to determining that the RSSI adjustment value is greater than the preset RSSI lower limit. The RSSI adjustment value is set to be the roaming threshold in response to determining that the RSSI adjustment value is less than or equal to the preset RSSI lower limit.
