[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Figure 1 It is a schematic diagram of a V2V communication scenario according to an embodiment of the present invention. Figure 1Shown is a schematic diagram of four vehicles on a lane communicating with each other.

[0038] V2V communication can achieve assisted driving and autonomous driving through wireless communication between multiple on-board units (OBU), thereby effectively improving traffic efficiency, avoiding traffic accidents and reducing driving risks.

[0039] Figure 2 and Figure 3 They are schematic diagrams of application scenarios of embodiments of the present invention. Figure 2 and Figure 3 In the example, UE 20 can communicate directly with base station 10, and UE 20 can be called a relay UE. UE 30 may not be able to communicate directly with base station 10, but UE 30 can communicate with UE 20, and then UE 30 can communicate with base station 10 through UE 20, and UE 30 can be called a remote UE.

[0040] Figure 2 In the embodiment, the communication distance between UE 20 and UE 30 with which it can communicate is relatively small, for example, about 10 meters (m). Figure 3 In the embodiment, the communication distance between UE 20 and UE 30 with which it can communicate is relatively large, for example, about 100 m to 1000 m.

[0041] against Figure 2 and Figure 3 illustrative scenario, Figure 4 It is a schematic diagram of a practical application scenario of an embodiment of the present invention. Figure 4 The evolved NodeB (eNB) in Figure 2 and Figure 3 The base station 10 in. Figure 4 The road side unit (RSU) and UE1, UE2 and UE3 in Figure 2 and Figure 3 UE 20 and UE 30 in the example, RSU is UE 20, which can communicate directly with eNB; UE1, UE2 and UE3 are UE 30, which can communicate with eNB through RSU. Figure 4 Also shown is a Global Navigation Satellite System (GNSS), which can be used to provide positioning information and other information to other network elements.

[0042] Among them, RSU can be a function of a vehicle-mounted device or an eNB. Among them, UE1, UE2 and UE3 can refer to vehicle-mounted devices, and vehicle-mounted devices can communicate with each other via sidelinks. The vehicle-mounted devices move with the vehicle at high speed. For example, when UE1 and UE2 move relative to each other, they have the maximum relative movement speed.

[0043] Figure 4 The devices shown in the figure can use the spectrum of cellular links or the spectrum of intelligent transportation near 5.9 GHz when communicating with each other. The technology for communication between the devices can be enhanced based on the LTE protocol or based on the D2D technology.

[0044] In an embodiment of the present invention, a side link may refer to a communication link between UEs, which is also referred to as a D2D link in D2D communication, and is also referred to as a PC5 link in some scenarios. In the Internet of Vehicles, it may also be referred to as a V2V link, or a vehicle-to-infrastructure (V2I) link, or a vehicle-to-pedestrian (V2P) link, etc. The side link may send information in any form of broadcast, unicast, multicast, or groupcast. Among them, the side link may use the spectrum of a cellular link, for example, using the uplink spectrum of a cellular link.

[0045] In the embodiment of the present invention, UE may also be referred to as a terminal, and may include an OBU on a vehicle, an RSU on the roadside, and a mobile phone used by pedestrians.

[0046] V2V communication recommends placing control information (such as SA) and data (Data) in the same subframe, such as Figure 5 shown. Figure 5 In (a), SA and Data are in non-adjacent frequency domains in the same subframe; Figure 5 In (b), SA and Data are in adjacent frequency domains of the same subframe. That is, the positions of SA and Data in the frequency domain can be adjacent or non-adjacent. In addition, SA can be carried in an independent physical channel, such as the Physical Sidelink Control Channel (PSCCH). Alternatively, SA can also be carried in the same physical channel as data, such as the Physical Sidelink Shared Channel (PSSCH).

[0047] Among them, in the D2D protocol of Rel-12, the channel where SA is located is also called PSCCH channel, which is a channel used to transmit control information between UEs. This control information is used to indicate to the receiver the location of the time-frequency resources for transmitting the data part, resource size, modulation and coding scheme (MCS) value and other parameter information. In the D2D of Rel-12, SA and data are located in different subframes, so their transmission power can be configured independently in each subframe.

[0048] It should be noted that, although in the current LTE system, the duration of a subframe is generally 1 millisecond (ms), in the embodiment of the present invention, the duration of a subframe is not limited. Specifically, in the embodiment of the present invention, the duration of a subframe can be the most basic duration occupied by a transmission, and the duration of a subframe can be a predefined length. For example, it can be 1ms; it can also be greater than 1ms, such as 2ms, 10ms; it can also be less than 1ms, such as 0.625ms, 0.125ms, 0.2ms, etc.

[0049] Since the parallel transmission of SA and data is based on a multi-carrier system, the total available transmit power for a transmitter in a subframe is fixed, such as not exceeding the maximum transmit power of the UE. For the scenario where SA and data are in a subframe, when the base station instructs the user equipment (UE) to use the maximum transmit power, if SA uses the maximum transmit power, there is no available transmit power for data, and vice versa.

[0050] The embodiment of the present invention aims to solve the problem of how to determine the transmit power of the data channel and the control channel when the UE needs to transmit both SA and data in the same subframe. In particular, when the UE has the maximum transmit power, how to determine the transmit power of the control information and the data respectively.

[0051] First link: refers to the communication link between UEs. It can be a D2D link, a V2X link, or a side link. For example, it can be the aforementioned Figure 2 or Figure 3 The link between UE 20 and UE 30 may be the aforementioned Figure 4 The communication on the first link can be based on any one of unicast, multicast and broadcast.

[0052] Second link: represents the communication link between the UE and the base station. It can be a cellular link. For example, it can be the aforementioned Figure 2 or Figure 3The link between UE 20 / UE 30 and base station 10 may be the aforementioned Figure 4 The link between RSU and eNB.

[0053] Relay UE: Relay UE refers to a UE that can communicate directly with the base station and can relay data from other UEs to the base station. For example, it can be the aforementioned Figure 2 or Figure 3 The UE 20 in the embodiment may be the aforementioned Figure 4 RSUs in.

[0054] Remote UE: A remote UE is a UE that may not be able to communicate directly with the base station, but can communicate with the base station through a relay UE. For example, it can be the aforementioned Figure 2 or Figure 3 The UE 30 in the embodiment may be the aforementioned Figure 4 UE1, UE2 and UE3 in it.

No matter how the UE allocates the transmission power of the control channel and the data channel, the sum of the transmission power of the control channel and the transmission power of the data channel should not exceed the maximum transmission power allowed by the first link.

Similarly, the power involved in the subsequent embodiments of the present invention can be determined as a logarithmic value or a linear value according to its unit. For example, The maximum transmission power is expressed as a linear value, and P CMAX,c The maximum transmission power is expressed in logarithmic terms. In the present invention, other parameters x representing power are also expressed in logarithmic terms. represents the linear value of parameter x, and x represents the logarithmic value of parameter x.
