In this embodiment, the network device may send network information including path loss indication information to the terminal device, where the path loss indication information is used to determine path loss, and the terminal device may receive the network information and perform uplink transmission based on the network information, thereby providing a scheme for performing uplink transmission when the terminal device communicates with a network device that only supports a receiving function. In addition, the network equipment with the downlink sending function sends the network information, so that the terminal equipment can know the path loss, and then uplink transmission is carried out according to the network information, thereby ensuring that uplink data can be sent out at reliable transmission power and realizing the reliability of transmission.
In this embodiment, the terminal device may communicate with a first network device having downlink transmission capability and a second network device not having downlink transmission capability. 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.
The network device without downlink transmission capability may refer to a network device that is completely unable to perform downlink transmission, or a network device that is unable to send information (e.g., a path loss reference signal) for determining a path loss by the terminal device. A network device with downlink transmission capability may refer to a network device capable of transmitting any downlink information (including downlink data information and downlink control signaling), or may transmit information (e.g., a path loss reference signal) for a terminal device to determine a path loss.

In this embodiment, the path loss indication information may directly indicate the path loss value, and the terminal device may directly obtain the path loss value from the path loss indication information.
The path loss indication information may also indicate Reference Signal Received Power (RSRP) (for example, RSRP of a path loss Reference Signal or RSRP of an uplink Signal), in this case, the terminal device may obtain Signal transmission Power, and after obtaining RSRP through the path loss indication information, the path loss may be obtained through calculation. The signal transmission power in the embodiment of the present application may be transmission power of an uplink signal, or may also be transmission power of a path loss reference signal. The path loss reference signal in the embodiment of the present application may be sent by a first network device. When the signal transmission power is the transmission power of the path loss reference signal, the path loss is the difference between the transmission power of the path loss reference signal and the reception power of the path loss reference signal. When the signal transmission power is the transmission power of the uplink signal, the path loss is the difference between the signal transmission power and the uplink signal reception power.
The path loss indication information may also indicate a path loss offset, that is, an offset relative to a reference path loss, where the reference path loss refers to a path loss calculated based on the transmission power of the path loss reference signal and the RSRP value of the path loss reference signal, and actually refers to a path loss between a station (e.g., a first network device) having downlink and uplink transmission capabilities and a terminal device; in this case, the terminal device determines a path loss between the terminal device and a station (e.g., a second network device) having no downlink transmission capability by calculating a reference path loss and by referring to the path loss and the path loss offset.
The path loss indication information may also indicate a reference signal received power offset (e.g., a received power offset of a path loss reference signal), which is an offset with respect to a reference RSRP, where the reference RSRP refers to an RSRP of the path loss reference signal, and actually refers to an RSRP of the path loss reference signal sent by a station (e.g., a first network device) with downlink and uplink transmission capabilities; in this case, the terminal device calculates the reference RSRP, determines the actual RSRP by the reference RSRP and the reference signal received power offset, and calculates the path loss by using the actual RSRP and the signal transmission power.
It should be noted that, the specific way of calculating the path loss is well known to those skilled in the art, and the embodiment of the present application does not limit this way.
In one non-limiting embodiment, the network information may be transmitted in any one or more of the following ways 1-4.
Mode 1, a network device sends an RRC signaling, and a terminal device receives the RRC signaling, where the RRC signaling includes network information.
Mode 2, a network device sends Media Access Control (MAC) signaling, such as a MAC Element (CE). The terminal equipment receives MAC signaling, and the MAC signaling comprises network information.

In particular, the identity of the dedicated logical channel is used to indicate one or more of: the MAC signaling includes network information for PUSCH, the MAC signaling includes network information for PUCCH, and the MAC signaling includes network information for Sounding Reference Signal (SRS). That is, the etlcid may indicate that this CE is network information for configuring/indicating the PUSCH; the eLCID may also indicate that this MAC CE is network information for configuring/indicating PUCCH; the etlcid may also indicate that this MAC CE is network information for configuring/indicating SRS.
Optionally, the MAC signaling is a MAC Random Access Response (RAR).
Mode 3, the network device sends Downlink Control Information (DCI), and the terminal device receives the DCI, where the DCI includes or indicates the network Information.
In the manner 3, the DCI may include one or more of a user-specific scheduled DCI, a user-specific non-scheduled DCI, and a common DCI.
For the non-scheduled DCI dedicated to the user, a value of a predefined field in the non-scheduled DCI dedicated to the user is a first value, and/or the non-scheduled DCI includes the Network information when a Physical Downlink Control Channel (PDCCH) carrying the non-scheduled DCI dedicated to the user is scrambled by using a preset Radio Network Temporary Identity (RNTI).
Further, for user-specific non-scheduled DCI, the network information is indicated using one or more of the following fields: a precoding information field;
a layer number field (Precoding information and number of layers);
a hybrid automatic repeat process number field (HARQ process number);
an Antenna port field (Antenna port);

a Time domain resource allocation field (Time domain resource assignment);
a Frequency domain resource allocation field (Frequency domain resource allocation);
a sounding reference signal request field (SRS request);
demodulation reference signal sequence initialization field (DMRS sequence initialization).
For the common DCI, the network information is included in the common DCI under the condition that a PDCCH carrying the common DCI is scrambled by using a special RNTI. After determining that the common DCI includes the network information, the terminal device acquires the network information thereof according to the information configured by the high layer and the corresponding field position in the DCI. Specifically, the network device sends higher layer configuration information. Correspondingly, the terminal equipment receives the high-level configuration information, determines a field corresponding to the terminal equipment in the public DCI according to the high-level configuration information, and acquires the network information in the field corresponding to the terminal equipment.
In embodiment 3, the DCI is DCI format 1_0 scrambled by random RNTI (RA-RNTI) or message BRNTI (MsgB-RNTI).
In the method 3, network information is indicated by using reserved bits of DCI 1_0, or DCI 1_0 includes indication information (denoted as first indication information), and the first indication information is used to indicate whether the RAR scheduled by the RAR includes network information.
In the method 3, the DCI further includes invalidation indicating information for indicating invalidation, that is, ignorable, of the network information indicated by the DCI.
For example, the invalid indication information may be indicated by a field in the DCI different from the field indicating the network information. Or, determining the validity of the network information according to a code point value of a field indicating the network information in the DCI, for example, ignoring the field if the code point value is 0.
Further, when the invalid indication information is indicated by a field other than the field indicating the network information field in the DCI, the invalid indication information may be judged based on information indicated by a Transmit Power Control (TPC) field in the DCI. For example, when the TPC control Field (Command Field) is 0, the TPC control Field is invalid indication information, that is, the TPC control Field may be considered to have no network information or ignore network information.
In one non-limiting embodiment, the terminal device may calculate other power control parameters, such as the signal transmit power described above. Specifically, the reaction can be carried out in any one or more of the following modes a to H.
The method A comprises the steps of calculating a first path loss based on the reference signal receiving power of a path loss reference signal; and if the first path loss is smaller than a first preset threshold, determining the sending power of the terminal equipment and the second network equipment for uplink transmission according to the reference signal receiving power of the path loss reference signal.
In the mode a, if the first path loss value calculated by the terminal device based on the RSRP value of the path loss reference signal is smaller than the first preset threshold, the terminal device obtains the sending power for performing uplink transmission between the terminal device and the second network device based on the RSRP value of the path loss reference signal.
Mode B, calculating a first path loss based on the reference signal received power of the path loss reference signal; and if the first path loss is greater than or equal to the first preset threshold, determining the sending power of uplink transmission between the terminal equipment and the second network equipment based on the path loss obtained by the network information.
In the mode B, if the first path loss value calculated by the terminal device based on the RSRP value of the path loss reference signal is greater than or equal to the first preset threshold, the terminal device obtains the transmit power for performing uplink transmission between the terminal device and the second network device based on the path loss obtained by the network information. The path loss obtained based on the network information may be, for example, the path loss obtained based on an RSRP value or a reference signal received power offset included in the network information, or a path loss value or a path loss offset.
Here, "less than" in the mode a may be replaced with "less than or equal to", and "greater than or equal to" in the mode B may be replaced with "greater than".
