Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control message including a first parameter and a second parameter. The first parameter may identify a first uplink control channel resource set for a first type of UE. The second parameter may identify a second uplink control channel resource set for a second type of UE. In some cases, a UE may receive the control message before receiving configuration information identifying a uplink control channel resource configuration. In some cases, a UE may optionally select an uplink control channel resource set based at least in part on the control message and a type of the UE. Also, a UE may transmit on an uplink using a communication configuration associated with the selected uplink control channel resource set. Numerous other aspects are provided.

A discovery and provisioning method. The method includes: A first device in an unprovisioned state sends a first message through a first antenna, where the first message is used by a second device to discover the first device, and the first message includes a device identifier of the first device; when a distance between the second device and the first device is less than or equal to a preset distance, the second device receives the device identifier sent by the first device; and after being discovered by the second device, the first device performs provisioning by using a second antenna.

This application relates to the field of communication technologies, and discloses a communication method and apparatus. The terminal device determines, depending on a second information from a network device and whether a terminal device supports uplink service transmission through a second network device, a parameter used to perform cell selection or cell reselection.

In embodiments, a wireless device may determine a downlink path loss based on a downlink signal received from a base station, send via an uplink (UL) receive (Rx) point an initial access signal using a first uplink transmit power based on the downlink path loss, receive an initial access response signal including a transmit power control (TPC) command and an uplink transmit power adjustment, and send a signal to the base station via the UL Rx point using a second uplink transmit power based on the TPC command and the uplink transmit power adjustment. The base station may receive the initial access signal using the first uplink transmit power via the UL Rx point, determine the TPC command and the uplink transmit power adjustment based on the initial access signal, and send to the wireless device the TPC command and the uplink transmit power adjustment.

The present disclosure discloses a method and a device in nodes used for wireless communications. A first node first receives a first radio signal and a second radio signal; and then determines that transmitting power of first control information in a first time window is a first power value and transmitting power of second control information in a second time window is a second power value; and transmits the first control information in the first time window with the first power value; the first power value is unrelated to the second power value, and the second power value is relevant to whether the first time window overlaps with the second time window. The present disclosure designs power allocation priorities of first control information and second control information to optimize both transmission performance and efficiency of a feedback channel in sidelink.

The present invention relates to an apparatus and method for controlling uplink transmission power in a multiple element carrier wave system. The method for controlling uplink transmission power by a terminal in a multiple element carrier wave system includes the steps of: generating an uplink signal to be transmitted in a first serving cell; receiving, from a base station, random access start information for commanding the start of a random access procedure for a second serving cell; calculating the estimated surplus power from first transmission power scheduled for an uplink signal transmission, and second transmission power scheduled for a transmission of a PRACH to which a random access preamble is mapped; and when the estimated surplus power is smaller than a threshold power, adjusting the first transmission power or the second transmission power on the basis of power allocation priority.
