In this embodiment, the terminal device may communicate with a first network device capable of downlink transmission and a second network device not capable of downlink transmission. In order to determine the path loss between the terminal device and the second network device without downlink transmission capability and complete uplink transmission, the terminal device may determine the path loss through network information sent by the first network device with downlink transmission capability.

Wherein, the network device without downlink transmission capability may refer to a network device that cannot perform downlink transmission at all, or a network device that cannot send information (for example, a path loss reference signal) for terminal devices to determine path loss. A network device capable of downlink transmission may refer to a network device capable of sending any downlink information (including downlink data information and downlink control signaling), or may send information for terminal devices to determine path loss (for example, path loss reference signal ) network device.

The network device in this embodiment is the first network device capable of downlink transmission. The first network device may configure and send network information for the terminal device to determine the path loss with the second network device not capable of downlink transmission, and perform uplink transmission. The network devices appearing in the following embodiments all refer to the first network device.

The path loss indication information may also indicate the reference signal received power offset (for example, the received power offset of the path loss reference signal), which is an offset relative to the reference RSRP, and the reference RSRP is the RSRP of the path loss reference signal, In fact, it refers to the RSRP of the path loss reference signal sent by a station with downlink and uplink transmission capabilities (for example, the first network device); in this case, the terminal device calculates the reference RSRP, and receives the reference RSRP and reference signal The power offset determines the actual RSRP, and then uses the actual RSRP and signal transmission power to calculate the path loss.

In manner 3, the DCI may include one or more of user-specific scheduling DCI, user-specific non-scheduling DCI, and public DCI.

For the user-specific non-scheduled DCI, the value of the predefined field in the user-specific non-scheduled DCI is the first value, and/or, a preset radio network temporary identity (Radio Network Temporary Identity, RNTI) is used In the case of scrambling a Physical Downlink Control Channel (PDCCH) carrying the user-specific non-scheduled DCI, the user-specific non-scheduled DCI includes the network information.

Further, for user-specific non-scheduled DCI, one or more of the following fields are used to indicate the network information: precoding information field;

Layer number field (Precoding information and number of layers);

HARQ process number field (HARQ process number);

Antenna port field (Antenna port);

Time domain resource assignment field (Time domain resource assignment);

Frequency domain resource assignment field (Frequency domain resource assignment);

Sounding reference signal request field (SRS request);

For the common DCI, in the case of using a dedicated RNTI to scramble the PDCCH carrying the common DCI, the common DCI includes the network information. After determining that the public DCI includes the network information, the terminal device obtains its own network information according to the information configured by the upper layer and the corresponding field position in the DCI. Specifically, the network device sends high-level configuration information. Correspondingly, the terminal device receives the high-level configuration information, determines the field corresponding to the terminal device in the public DCI according to the high-level configuration information, and acquires network information in the field corresponding to the terminal device.

In mode 3, DCI is DCI format 1_0 scrambled by random RNTI (RA-RNTI) or message BRNTI (MsgB-RNTI).

In mode 3, the reserved bit of DCI 1_0 is used to indicate network information, or DCI 1_0 includes indication information (referred to as first indication information), and the first indication information is used to indicate whether the scheduled RAR includes network information.

In mode 3, the DCI further includes invalid indication information, which is used to indicate that the network information indicated by the DCI is invalid, that is, it can be ignored.

Exemplarily, the invalid indication information may be indicated through a field in the DCI that is different from the field indicating the network information. Alternatively, the validity of the network information is determined according to the code point value of the field indicating the network information in the DCI, for example, if the code point value is 0, this field is ignored.

Further, when the invalidation indication information is indicated by a field different from the field indicating the network information in the DCI, the invalidation indication information may be determined based on information indicated by the Transmit Power Control (TPC) field in the DCI. For example, when the TPC control field (Command Field) is 0, it is invalid indication information, that is, it can be considered that there is no network information or the network information is ignored.
