A gap-free measurement method is as follows: A terminal device receives, from an access network device, configuration information used to indicate the terminal device to perform gap-free measurement on a neighboring cell of a serving cell of the terminal device. The terminal device determines, based on the configuration information, radio frequency channels of a resource unit to be measured in the neighboring cell are some or all of radio frequency channels of a second resource unit, where the second resource unit is included in a first resource unit combination, and the first resource unit combination is included in a resource unit combination that is configured for the terminal device and in an active state. The terminal device performs gap-free measurement on a first cell on some or all of radio frequency channels of the second resource unit.

Gap-free measurement method and apparatus

This application provides a power configuration method and an apparatus, so that a terminal device is enabled to allocate as much uplink transmit power as possible to a first port, and allocate first transmit power as transmit power of a second port, so that total transmit power of the terminal device reaches calculated transmit power indicated by a network device for sending; or both the first port and the second port are enabled to be used to perform sending by using respective maximum transmit power supported by the first port and the second port, so that receive power of the network device to receive an uplink signal is maximized, thereby improving uplink performance.

Power configuration method and apparatus

The present disclosure relates to channel conflict processing methods and apparatus. In one example method, when a terminal device establishes a connection relationship with a source cell, and sends a connection request to or establishes a connection relationship with a target cell, the terminal device detects whether an uplink channel conflict occurs on an uplink channel of the source cell and an uplink channel of the target cell, where the source cell and the target cell are infra-frequency or intra-band contiguous inter-frequency. If the terminal device determines that an uplink channel conflict occurs, the terminal device sends a signal on an uplink channel with a higher priority between the uplink channel of the source cell and the uplink channel of the target cell.

Channel conflict processing method and apparatus

A measurement configuration method and an apparatus are provided. The method includes: a network device transmits measurement configuration information to a terminal device, where the measurement configuration information includes first information indicating that an MG is active when a frequency of an SSB that is indicated by an MO of a first serving cell of the terminal device is out of a currently active BWP of the first serving cell; and after the active BWP of the first serving cell of the terminal device is switched from a first BWP to a second BWP, the terminal device determines, based on the first information, that the MG in the measurement configuration is active, where the second BWP does not include the frequency of the SSB that is indicated by the MO corresponding to the first serving cell.

Measurement configuration method and apparatus

A measurement configuration method includes a network device that determines when a bandwidth part (BWP) occupied by a terminal device is switched from a first BWP to a second BWP. The network device sends first information to the terminal device, indicating whether configuration information of a first measurement window takes effect when the terminal device occupies the second BWP and indicating whether the first measurement window is configured for the first BWP.

A Physical Random Access Channel (PRACH) resource selection method includes a terminal device receiving N synchronization signal blocks (SSBs) from an access device, determining a target PRACH resource selection manner based on at least one of a service type, a type of a trigger event that triggers random access, a signal strength change status of a reference signal received by the terminal device, mobility of the terminal device, and historical information, and selecting, in the determined selection manner, a target PRACH resource from N PRACH resources corresponding to the N SSBs.

PRACH resource selection method and apparatus

A computer-implemented method for operating a user equipment (UE) includes measuring a channel quality of a channel associated with a first uplink channel and a second uplink channel, determining that the channel quality is between a first channel quality threshold and a second channel quality threshold, and based thereon, selecting either the first uplink channel or the second uplink channel for an uplink transmission in accordance with a current location of the UE, historical information of successful uplink channel access attempts, and a distance threshold, and performing an uplink random access procedure in accordance with the selected uplink channel.

System and method for communications using supplementary uplink

A frequency domain resource activation method, a device, and a system, the method including determining, by a terminal, first information, where the first information includes at least one of information used to request that an access network device configure or activate a frequency domain resource unit of the terminal, or first assistance information of a frequency domain resource unit of the terminal, and where the frequency domain resource unit is a bandwidth part (BWP), and sending, by the terminal, the first information to the access network device.

Method and devices for communication of information regarding a frequency resource unit

This application relates to the wireless communications field, and discloses a random access method and apparatus, to resolve a problem of how a terminal device selects an uplink to perform random access. The method includes: selecting, by a terminal device, a first uplink from at least two preconfigured uplinks to perform random access; and selecting, by the terminal device when random access performed by using the first uplink fails, a second uplink from the at least two uplinks to perform random access, where the at least two uplinks are communications links between the terminal device and a first network device, the first network device and the terminal device are located in a same cell, the first uplink is a normal uplink NUL, and the second uplink is a supplementary uplink SUL. In this way, the terminal device selects an uplink to perform random access.
