Background technique

In the field of communication technology, during communication between a base station and a user equipment (UE), the base station performs uplink scheduling on the UE to achieve communication.

One method for the base station to perform uplink scheduling on the UE may be: the base station allocates uplink transmission resources to the UE according to the UE's power headroom (ie, PH, power headroom), or it may be understood that the base station allocates uplink transmission resources to the UE according to the UE's own capabilities , So that the UE completes uplink data transmission according to the uplink transmission resources allocated to it. Specifically, after the UE determines the power headroom of the UE, the UE reports the power headroom of the UE to the base station, and then the base station allocates uplink transmission resources to the UE according to the power headroom of the UE. For example, when the power headroom of the UE is small, the base station allocates less uplink transmission resources to the UE when scheduling the UE, so that resources can be saved; when the power headroom of the UE is larger, the base station can allocate more to the UE In this way, the uplink transmission resources of the UE can increase the uplink transmission rate of the UE.

However, in the above method, the power margin reported by the UE is the power margin of the Uu port link between the UE and the base station, and with the development of communication technology, after the introduction of D2D communication or V2X communication, the communication link of the UE It may also include a link (ie, a sidelink link) between the UE and other terminal equipment (such as a vehicle-mounted unit).

It should be noted that in the embodiments of the present application, the first communication device may be a terminal device, and the second communication device may be a base station or another terminal device, and the following embodiments will not be described.

The following two different implementations are described in detail from the perspective of the interaction between the first communication device and the second communication device to illustrate the complete process of power headroom reporting.

First, the first implementation manner is introduced. As shown in FIG. 5, the method for reporting the power headroom provided by the embodiment of the present application may include S101-S104:

S101. The first communication device generates a power headroom report, where the power headroom report includes the power headroom of the first communication device and indication information of the power headroom.

The indication information of the power headroom is used to indicate the attribute of the power headroom of the first communication device.

In the embodiment of the present application, the attributes of the power headroom may include any one or several of the following: link attributes of the power headroom, cell attributes of the power headroom, network attributes of the power headroom, and power headroom. Mixed attributes.

Exemplarily, the above link attributes include the first link and/or the second link, that is, the power headroom of the first communication device is the power headroom corresponding to the first link, or the power headroom of the first communication device Is the power headroom corresponding to the second link, or the power headroom of the first communication device is the power headroom corresponding to the first link and the power headroom corresponding to the second link, or the power of the first communication device The margin is the sum of the power margins corresponding to the first link and the second link (that is, the total power margins corresponding to the first link and the second link). Wherein, the first link is a wireless access link (also called Uu port link) between the first communication device and the base station, and the second link is between the first communication device and other terminal equipment Wireless direct link (also called sidelink link).

It should be noted that, in the embodiment of the present application, different links may be carried on different carriers, for example, the first link is carried on the first carrier, and the second link is carried on the second carrier. Exemplarily, The first communication device sends information on the first link on the first carrier, and sends information on the second link on the second carrier; different links can also be carried on the same carrier, such as the first link Both the channel and the second link are carried on the first carrier. Exemplarily, the first communication device is on the same carrier, and information is transmitted on the first link and the second link at the same time. When the first communication device reports the power headroom, the first communication device may carry the power headroom corresponding to the first link and the power headroom corresponding to the second link in different locations (for example, MAC in the following embodiment) Two different bytes in the report), the first communication device may also sum the power headroom corresponding to the two links to obtain the total power headroom, and then carry the total power headroom as a whole Report in a location (for example, a byte pair of MAC and CE in the following embodiment).

The power headroom of the first communication device is the power headroom corresponding to the first link and the power headroom corresponding to the second link is carried in different locations and reported. The power headroom of the first communication device is the first link The sum of the power headrooms corresponding to the channel and the second link corresponds to the case where the sum of the two power headrooms is carried as a whole and reported at one location, and the following embodiments will not be described repeatedly.

Optionally, the first standard may be LTE, the second standard may be 5G NR, then the first standard network is an LTE network, and the second standard network is a 5G NR network. In the embodiment of the present application, the first standard is For LTE, the second standard is 5G. NR is used as an example to introduce the power headroom reporting method. Of course, the first standard and the second standard may also be other existing or future network standards that will be defined. This is not specifically limited.

The cell attribute of the power headroom may include: the cell corresponding to the second link is a single cell or multiple cells, and the cell attribute of the power headroom is mainly used to indicate that the power headroom corresponding to the second link reported by the first communication device is The power headroom corresponding to a single cell is also the power headroom corresponding to multiple cells. It can be understood that, in the embodiment of the present application, different cells correspond to different carriers, that is, different carriers carried by the first communication device are used to divide the cell where the first communication device is located.

For the first link, the cell where the first communication device is located may include a primary cell (which may be denoted as PCell), a secondary cell (which may be denoted as SpCell), and other serving cells (which may be denoted as Serving Cell), where, The primary cell refers to the primary cell corresponding to the primary base station of the first communication device, the secondary cell refers to the primary cell corresponding to the secondary base station of the first communication device, and the other serving cells refer to the primary and secondary base stations except the primary cell Other service areas.

Of course, different carriers on the wireless direct link may not be called cells, but defined as other names, which are not limited in the embodiments of the present application.

The network attributes of the power headroom may include: a wireless communication standard corresponding to the second link, and the wireless communication standard includes a first standard and/or a second standard, and refers to the first network standard and/or the second network standard. In this way, the network attribute of the power headroom is mainly used to indicate whether the power headroom corresponding to the second link reported by the first communication device is the power headroom corresponding to the second link in the first-standard network or the second-standard network The power headroom corresponding to the second link is also the power headroom corresponding to the second link in the first-standard network and the power headroom corresponding to the second link in the second-standard network, or the second link in the first-standard network The sum of the power headroom corresponding to the second link in the second-standard network (that is, the total power headroom corresponding to the second link in the first-standard network and the second link in the second-standard network).

Similarly, reference may be made to the above description of the sum of the power headrooms corresponding to the first link and the second link. In the embodiment of the present application, networks of different standards may be carried on different carriers, for example, network bearers of the first standard On the first carrier, the second-standard network is carried on the second carrier, and networks of different standards may also be carried on the same carrier, for example, both the first-standard network and the second-standard network are carried on the first carrier. In the case where the first-standard network and the second-standard network are carried on the same carrier, when the first communication device reports the power margin, the first communication device may compare the power margin and the corresponding power margin of the second link in the first-standard network The power headroom corresponding to the second link in the second-standard network is carried in different locations (for example, two different byte pairs in the MAC and CE in the following embodiments) for reporting. The first communication device may also report the two The power headroom corresponding to the second link in a standard network is summed to obtain the total power headroom, and then the total power headroom is carried as a whole in a location (for example, a word of MAC CE in the following embodiment Report in section ).

The power headroom corresponding to the second link reported by the first communication device is the power headroom corresponding to the second link in the first-standard network and the power headroom corresponding to the second link in the second-standard network is carried in different The situation of reporting the position; the sum of the power headrooms corresponding to the second link in the first-standard network and the second link in the second-standard network corresponds to the case of carrying the sum of the two power headrooms as a whole to report at one location, The following embodiments will not be repeated.

The mixed attribute of the above power headroom includes any one of the following: the power headroom is the power headroom corresponding to the first link, the power headroom is the power headroom corresponding to the second link, and the power headroom is the first link The corresponding power headroom corresponds to the power headroom corresponding to the second link, the power headroom is the sum of the power headroom corresponding to the first link and the second link, and the power headroom is the second link in the first-standard network The corresponding power headroom and power headroom are the power headroom corresponding to the second link in the second-standard network, and the power headroom is the power headroom corresponding to the second link in the first-standard network and the second The sum of the power headroom corresponding to the second link and the power headroom corresponding to the second link in the first-standard network and the second link in the second-standard network.

In the embodiment of the present application, the first communication generating power headroom report includes determining various types of power headroom of the first communication device, and determining the power headroom indication information. The power headroom of the first communication device is the difference between the maximum transmission power value of the first communication device and the power already used by the first communication device. The power headroom of the first communication device indicates how much power the first communication device can use.

Exemplarily, for each cell, it corresponds to a different carrier, and different carriers may correspond to different maximum transmission powers. Therefore, for the first communication device, if there are N cells corresponding to the first communication device, the first communication The device corresponds to N maximum transmit power values. The N maximum transmit power values may be different or the same.

S102. The first communication device sends a power headroom report to the second communication device.

In the MAC CE shown in Fig. 7, the first line corresponds to one byte (that is, 8 bits), the second line corresponds to one byte, and the first two bits of the first line To reserve bits, the last six bits are used to carry power headroom. The power headroom is the power headroom of the main cell (ie, PCell), and the type of the power headroom is Type 1, which is PH (Type 1, PCell). The first two bits in the second row are reserved bits, and the last six bits are used to carry the maximum transmission power corresponding to the cell (ie, Pcell) where the first communication device is located (the maximum transmission power corresponding to the first communication device under the primary cell), That is, it is understood as the maximum transmission power corresponding to the carrier f of the serving cell c.
