For example, the terminal device in fig. 1 to 10 may be a vehicle user device and the network device may be a communication base station.
The method provided by the application can be applied to a communication system as shown in fig. 1 or fig. 2, and the system can realize mutual communication between terminal equipment when running, and can comprise the following two cases:
First case: the terminal device is in the coverage of the network device, the terminal device and the terminal device communicate through network device transfer, as shown in fig. 1, the first terminal device and the second terminal device communicate through network device transfer, illustratively, an uplink (as shown by an arrow) communication link between the first terminal device and the network device is an Uplink (UL), a downlink (as shown by an arrow) communication link between the network device and the second terminal device is a Downlink (DL), and the first terminal device or the second terminal device respectively performs wireless communication with the network device through a Uu port.
Second case: the terminal equipment is in the coverage of the network equipment or is not in the coverage of the network equipment, and the terminal equipment are in direct communication. As shown in fig. 2, the first terminal device and the second terminal device perform direct communication, and illustratively, a communication link between the first terminal device and the second terminal device may be a Side Link (SL), where the first terminal device and the second terminal device perform wireless communication through a PC5 port.
The SL communication resource for performing wireless direct communication between the first terminal device and the second terminal device may be scheduled by the network device, and illustratively, the wireless direct communication process between the terminal device and the terminal device is controlled by the network device, where the first terminal device serving as the data transmitting end may send the control signal and the data signal to the second terminal device serving as the data receiving end on the SL communication resource configured by the network device. This mode in which the base station schedules SL transmission resources may be referred to as a first mode; illustratively, the network device may schedule the side link transmission resources via downlink control information (downlink control information, DCI), i.e., the network device may dynamically schedule the side link resources; alternatively, the network device configures an authorized (configured grant) side link transmission resource, i.e., the network device may semi-statically configure the side link resource. Alternatively, the first mode may be a mode1 resource allocation mode or a mode3 resource allocation mode specified in a standard currently set forth by the third generation partnership project (3rd Generation Partnership Project,3GPP).
The SL communication resource for performing wireless direct communication between the first terminal device and the second terminal device may also be determined by the terminal device itself without being controlled by the network device schedule, and the network device configures an SL resource pool for the terminal device by using a system broadcast (System Information Block, SIB) message or a terminal device dedicated radio resource control (Radio Resource Control, RRC) signaling, where the first terminal device as a data transmitting end may autonomously acquire the SL communication resource from the SL resource pool to transmit a control signal and a data signal to the second terminal device as a data receiving end; or, the terminal device may, for example, obtain, by the first terminal device as a data transmitting end, an edge link communication resource from a SL resource pool preconfigured in master-slave to transmit a control signal, and/or transmit a data signal to the second terminal device as a data receiving end, outside the communication coverage of the network device. Optionally, the first terminal device searches for a suitable SL communication resource in the SL resource pool by itself monitoring the busy state of the channel to send the control signal and/or the data signal. Optionally, the first terminal device sends the control signal by competing with other terminal devices for the appropriate SL communication resources in the SL resource pool, and/or the higher the priority of the V2X service to be transmitted in the terminal device, the greater the chance that it competes for the appropriate SL communication resources in the SL resource pool. Optionally, the first terminal device may also pre-store the SL resource pool information, or the SL resource pool may be pre-configured by the network device when the first terminal device accesses the network. The mode in which the terminal device determines the SL transmission resource by itself may be referred to as a second mode; illustratively, the terminal device perceives or contends for the side link transmission resources. Alternatively, the second mode may be a mode2 resource configuration mode or a mode4 resource configuration mode specified in the standard currently made by 3 GPP.
In the present application, communication between the terminal device and the network device or between the terminal device and the terminal device may be unicast communication, multicast communication, or broadcast communication.
The network device may be a Master Node (MN) under a dual-link architecture, may be a Secondary Node (SN) under a dual-link architecture, may be an MN under a multi-link (MC) architecture, or may be an SN under an MC architecture, and the application is not limited to the type of network device. For example, a terminal device may have a communication connection with two network devices at the same time and may transmit and receive data, which may be referred to as dual-connectivity (DC). Alternatively, one of the two network devices may be responsible for interacting radio resource control messages with the terminal device and for interacting with a core network control plane entity, and then the network device may be referred to as a Master Node (MN) and the other network device may be referred to as a Secondary Node (SN). Similarly, if a terminal device can simultaneously have communication connections with multiple network devices and can transmit and receive data, it may be referred to as a multi-connectivity (MC). Alternatively, among the plurality of network devices, there may be one network device responsible for interacting radio resource control messages with the terminal device and for interacting with a core network control plane entity, and then the network device may be referred to as MN, and the remaining radio access network devices may be referred to as SN. The terminal device may maintain two media access control layer (Media access control, MAC) layer entities corresponding to the MN and SN, respectively. For example, there may be multiple carriers or cells on the Uu interface link between the terminal device and the MN, which may be referred to as a primary cell (primary serving cell, PCell), or a secondary cell (secondary serving cell, SCell), and there may be multiple carriers or cells on the Uu interface link between the terminal device and the SN, which may be referred to as a primary secondary cell (primary secondary serving cell, PSCell) and a secondary cell (secondary serving cell, SCell), which may be referred to herein as a special cell (specell, spCell).
It should be understood that fig. 1 and fig. 2 are only exemplary network architecture diagrams, and the network architecture further includes other network element devices or functional units, which are not limited in this application.
Fig. 3 is a schematic flow chart of a communication method provided in the present application, and a specific description will be given below on the technical scheme of the embodiment of the present application with reference to fig. 3. For example, the communication method 300 corresponding to fig. 3 may include:
operation 301: the terminal device receives information of a first duration from the network device.
For example, the first duration may be granularity of the terminal device, that is, the network device configures the first duration for a terminal device, and the network device may determine the first duration according to the capability of the terminal device, for example, the stronger the idle degree, the data processing capability, the radio frequency capability, and the like of the terminal device, the shorter the first duration may be. For example, the information of the first time period may include two time points, the first time period being an absolute value of a difference between the two time points; alternatively, the information of the first duration may include a duration, where the first duration is the duration.
The first duration may be link granularity, that is, the network device configures a first duration for a link of the terminal device, the terminal device may configure the first duration for a Uu port link of the terminal device, and may also configure the first duration for an edge link of the terminal device. For example, the information of the first time period may include four time points, wherein an absolute value of a difference between two time points is the first time period of the side link, and an absolute value of a difference between two other time points is the first time period of the Uu port link; alternatively, the information of the first duration may include two durations, the first duration of the side link and the first duration of the Uu port link, respectively.
Alternatively, the first duration may be carrier granularity, that is, the network device configures the first duration for a carrier, and the network device may further determine the first duration according to a subcarrier spacing (SCS) of a carrier supported by the terminal device, for example, the larger the SCS of the carrier is, the shorter the first duration may be. For example, the information of the first duration may include a plurality of time points, wherein an absolute value of a difference between two time points is the first duration of one carrier; or, the information of the first duration may include a plurality of first durations, where one first duration is the first duration of one carrier, and the terminal device may determine different first durations of different carriers of the terminal device according to the information of the first duration.
Optionally, the first duration may also be bandwidth part (BWP) granularity, and the information of the first duration may refer to the above description and will not be described herein.
Operation 301 is an optional operation, and exemplary, the terminal device stores the information of the first duration, for example, if the protocol or standard specifies the information of the first duration, the device manufacturer may store the information of the first duration in the terminal device before the terminal device leaves the factory, or the network device configures the information of the first duration into the terminal device in advance when the terminal device accesses the network, or the protocol or standard specifies an algorithm through which the first duration is determined, and the terminal device may determine the information of the first duration according to the algorithm, for example, the terminal device may determine the information of the first duration according to subcarrier interval information and/or the capability of the UE by itself, so that the network device does not need to send the information of the first duration to the terminal device.
Operation 302: the terminal device determines a first data transmission time.
The terminal device determines the first data transmission time by monitoring downlink control information (downlink control information, DCI) on a control channel of the second link, or a configured grant of data transmission resources (configured grant) already present by the terminal device.
For example, the first data transmission time may be determined by the terminal device based on the configured grant, for example, the first data transmission time is a start time of a data transmission resource corresponding to the configured grant; the configurable grant may be an grant that the terminal device may use without further grant, and the configurable grant may be a configurable grant corresponding to a first data transmission resource that may be used to transmit a PHR after the PHR trigger time.
For example, the first data transmission time may be determined by the terminal device based on DCI, e.g., the first data transmission time may be a start time of a data transmission resource scheduled by the DCI. Wherein the DCI may be a DCI scrambled by a cell-specific radio network temporary identity (cell specific radio network temporary identifier, CS-RNTI), the DCI may be caused by a terminal device requesting transmission resources for a power headroom report (power headroom report, PHR) report from a network device through a scheduling request (scheduling request, SR) or a buffer status report (buffer status report, BSR), and the DCI is used to allocate transmission resources for the PHR report, for example.
The configured grant or DCI may be for a carrier, that is, the carrier may be a carrier belonging to a Uu port link, or may be a carrier belonging to a side link.
Alternatively, the first data transmission time may be an uplink data transmission time, and the uplink data may include the PHR.
Optionally, the terminal device may determine the first data transmission time from the PHR trigger time.
The first link in fig. 3 is illustratively a direct wireless communication link between the terminal device and other terminal devices, the second link is a wireless communication link between the terminal device and the network device, and the first link is illustratively an edge link, and the second link is a Uu port link.
Operation 303: the terminal device determines a first time.
The terminal equipment determines the first time according to the first time length and the first data transmission time.
For example, the first time may be a time when the PHR is determined at the latest, and the first time may be a time obtained by subtracting the first time period from the first data transmission time.
Alternatively, the first time may be a time when the terminal device monitors the DCI, or the first time may be a first uplink symbol (symbol) transmitted at the first data transmission time minus a preparation time of a physical uplink shared channel (physical uplink shared channel, PUSCH).
Alternatively, the first time may be referred to as a PHR packing time, where the PHR packing time may refer to a time when the terminal device starts to determine various parameters included in the PHR, or may refer to a time when the terminal device starts to generate the PHR, for example, a time when the terminal device starts to pack a power headroom report media access layer control element (power headroom report media access control control element, PHR MAC CE).
Operation 304: the terminal equipment determines the resource allocation situation of the first link.
Illustratively, the first link is an edge link. For a clearer description of the method, the following will take an example that the terminal device includes an edge link, and the edge link includes a first carrier to describe how the terminal device determines the resource allocation situation of the edge link; the one side link may include a plurality of carriers, for example, the terminal device and other terminal devices communicate in a carrier aggregation manner, so that the side link between the terminal device and other terminal devices may include a plurality of carriers, where the resource allocation situation of each carrier may be determined by referring to the following method, which is not described herein. When the terminal device includes multiple side links, for example, the terminal device and the multiple terminal devices perform unicast communication, multicast communication or broadcast communication, multiple side links may exist between the terminal device and other terminal devices, and the resource allocation situation of each side link may be determined by referring to the following method, which is not described herein.
The terminal device may include an edge link that may include a first carrier, and determining the resource allocation of the edge link by the terminal device may include determining the resource allocation of the first carrier.
Optionally, the "first carrier of the side link" and the "first carrier of the Uu port link" are illustrated in this application, where the "first carrier of the side link" may be replaced by the "side link" and the "first carrier of the Uu port link" may be replaced by the "Uu port link" in this application, which is not described herein again.

The terminal device may monitor the resource allocation situation on the first carrier: when the first carrier wave is monitored to have the resource allocation of the side link obtained through the first mode, the terminal equipment determines the resource allocation of the side link with the first mode; wherein monitoring the resource allocation of the sidelink obtained by the first mode may comprise monitoring a configured grant of sidelink data transmission resources (configured grant), or monitoring a grant of sidelink data transmission resources sent by the network device, e.g. monitoring DCI for configuring the first mode resources;
When there is a resource allocation of the side link obtained through the second mode on the first carrier, the terminal device determines that there is a resource allocation of the side link of the second mode. Wherein monitoring the resource allocation of the side link obtained by the second mode may comprise monitoring that the terminal device perceives or contends for the side link data transmission resource, e.g. monitoring that the terminal device obtains the side link data transmission resource by the second mode.
When there is a resource allocation of the side link obtained by the first mode and/or the second mode on the first carrier, the terminal device determines that there is a resource allocation of the side link. When it is monitored that there is an existing configured grant of uplink data transmission resources (configured grant) on the first carrier, or DCI for allocating uplink resources, the terminal device may determine that there is resource allocation of Uu port link.
Optionally, the first resource configuration mode includes: the network device configures the side link transmission resources for the terminal device, which may include obtaining the side link resources through a first mode, and the second resource configuration mode includes: the terminal device selecting the side link transmission resources may include obtaining the side link resources through a second mode; alternatively, the second resource configuration mode includes: the network device configures the side link transmission resources for the terminal device may include obtaining the side link resources through a first mode, the first resource configuration mode including: the terminal device selecting the side link transmission resources may include obtaining the side link resources through a second mode.

Optionally, the terminal device determines the resource allocation situation of the side link at the first time, or at any time before the first time.
Optionally, the terminal device may determine the resource allocation situation of the side link from the power headroom report PHR trigger time, or at any time after the PHR trigger time.
Optionally, the terminal device may determine the resource allocation situation of the Uu link according to the first time while determining the resource allocation situation of the side link according to the first time.

The terminal device determines a power headroom report PHR according to the resource allocation situation of the side link, and may at least include any one of the following:
(1) the terminal equipment determines to calculate a power margin PH based on actual transmission or based on a reference format according to the resource allocation condition of the side link;

For a clearer description of the method, the following will take an example that the terminal device includes an edge link, and the edge link includes a first carrier to describe how the terminal device determines a power headroom report PHR; the side link includes a plurality of carriers, for example, the terminal device and other terminal devices communicate in a carrier aggregation manner, so that the side link between the terminal device and other terminal devices may include a plurality of carriers, and at this time, the power headroom report PHR of each carrier may be determined by referring to the following method, which is not described herein. When the terminal device includes multiple side links, for example, the terminal device and the multiple terminal devices perform unicast communication, multicast communication or broadcast communication, multiple side links may exist between the terminal device and other terminal devices, and the power headroom report PHR of each side link may be determined by referring to the following method, which is not described herein.
For example, the terminal device may include one side link, which may include the first carrier, and the terminal device may calculate the power headroom PH based on the actual transmission or based on the reference format according to the resource allocation situation of the first carrier of the side link.

Alternatively, considering whether carriers between the Uu port link and the side link can be shared and whether power between the first mode and the second mode of the Uu port link and the side link can be shared, the above (1) to (3) can be divided into 8 possible cases as shown in table 4 to specifically explain the above-mentioned power headroom report PHR method, taking the Uu port link and the side link as an example,
Table 4:
where, illustratively, the Uu port link and the sidelink do not share a carrier, it may be indicated that the same carrier may serve both the Uu port link and the sidelink, either exclusively, or not. Alternatively, the power sharing between the Uu port link and the side link may indicate that, in the power control, the sum of the Uu port link transmission power and the side link transmission power is smaller than a fixed value, that is, when the side link transmission power is 0, the Uu port link maximum transmission power may reach the fixed value, and, likewise, when the Uu port link transmission power is 0, the side link maximum transmission power may reach the fixed value. The shared power in table 4 may be understood with reference to the explanation of the Uu port link and the side link shared power, and will not be described herein. Table 4 shows only 8 possible cases, and the case of the above method is not limited to the case shown in table 4, for example, the carrier may be replaced with a bandwidth part (BWP), or the BWP may be configured on the carrier. The 8 cases in table 4 may be combined, for example, cases (1) to (8) may be combined, thus indicating the influence of the condition irrespective of whether the Uu port link and the side link share the first carrier or not and the condition irrespective of whether the power is shared between the Uu port link and the first mode or the second mode of the side link or not; for example, cases (1) to (4) may be combined with cases (5) to (8), respectively, which means that the influence of the condition that does not consider whether the Uu port link and the side link share the first carrier is taken into consideration; for example, (1) to (4) may be combined, or (5) to (8) may be combined, which means that the influence of the condition of whether or not the power is shared between the first mode and the second mode of the Uu port link and the side link is not considered. If the standard specifies or agrees with one or more of (1) - (8), then table 4 may eliminate the rows where the remaining cases are located to form a new table, or the terminal device may not consider the remaining cases. Alternatively, the terminal device may decide to operate in any one of (1) to (8) depending on the configuration of the network device. Alternatively, the terminal device may decide to operate in a certain case in (1) to (8) based on the stored configuration.
