For example, the features or contents identified by broken lines in the drawings related to the embodiments of the present application can be understood as optional operations or optional structures of the embodiments.
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.
For example, the method provided by the present application may be applied to a communication system as shown in fig. 1 or fig. 2, where the system operates to implement mutual communication between a terminal device and a terminal device, and the following two cases may be included:
in the first case: in the coverage area of the network device, the terminal device and the terminal device communicate with each other through the network device relay, as shown in fig. 1, the first terminal device and the second terminal device communicate with each other through the network device relay, illustratively, an Uplink (UL) communication link between the first terminal device and the network device in an uplink direction (as indicated by an arrow), a Downlink (DL) communication link between the network device and the second terminal device in a downlink direction (as indicated by an arrow), and the first terminal device or the second terminal device wirelessly communicates with the network device through the Uu interface, respectively.
In the second case: and the terminal equipment is in the coverage range of the network equipment or not in the coverage range of the network equipment, and direct communication is carried out between the terminal equipment and the terminal equipment. As shown in fig. 2, the first terminal device and the second terminal device perform direct communication, for example, a communication link between the first terminal device and the second terminal device may be a Sidelink (SL), and 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, for example, the terminal device is in a coverage area of the network device, a wireless direct communication process between the terminal device and the terminal device is controlled by the network device, and the first terminal device serving as the data sending end may send a control signal and a 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; for example, the network device may schedule the side link transmission resource through Downlink Control Information (DCI), that is, the network device may dynamically schedule the side link resource; alternatively, the network device configures the granted (configured grant) edge link transmission resource, i.e., the network device may semi-statically configure the edge link resource. Optionally, the first mode may be a mode1 resource allocation mode or a mode3 resource allocation mode specified in the current standards set by the third Generation Partnership Project (3 GPP).
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, rather than being scheduled and controlled by the network device, for example, the terminal device is in a communication coverage of the network device, the network device configures an SL Resource pool for the terminal device through a System broadcast (SIB) message or a Radio Resource Control (RRC) signaling dedicated to the terminal device, and the first terminal device serving as a data transmitting end may obtain the SL communication Resource from a master SL Resource pool and transmit a Control signal and a data signal to the second terminal device serving as a data receiving end; or, for example, the terminal device is outside the communication coverage of the network device, the first terminal device as the data sending end autonomously obtains the side link communication resource from the preconfigured SL resource pool to send the control signal, and/or the data signal is sent to the second terminal device as the data receiving end. Optionally, the first terminal device finds a suitable SL communication resource in the SL resource pool to send the control signal and/or the data signal by monitoring the busy-idle state of the channel by itself. Optionally, the first terminal device sends the control signal and/or the data signal by contending with another terminal device to obtain an appropriate SL communication resource in the SL resource pool, where the higher the priority of the V2X service to be transmitted in the terminal device is, the greater the chance that the first terminal device contends for the appropriate SL communication resource in the SL resource pool is. Optionally, the first terminal device may also pre-store the SL resource pool information, or the network device pre-configures the SL resource pool 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 end devices sense or compete for edge link transmission resources. Optionally, the second mode may be a mode2 resource configuration mode or a mode4 resource configuration mode specified in the standard established by the current 3 GPP.
In this application, the 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 base station (MN) in a dual-link architecture, may be a secondary base Station (SN) in a dual-link (DC) architecture, may be an MN in a multi-link (MC) architecture, or may be an SN in an MC architecture, and the type of the network device is not limited in this application. Illustratively, a terminal device may be in communication connection with two network devices at the same time and may transmit and receive data, which may be referred to as a dual-connectivity (DC). Optionally, one of the two network devices may be responsible for interacting with the terminal device for radio resource control messages and interacting with a core network control plane entity, so that the network device may be referred to as a Master Node (MN), and the other network device may be referred to as a secondary base Station (SN). Similarly, if the terminal device can simultaneously have communication connection with a plurality of network devices and can transmit and receive data, it may be referred to as a multi-connection (MC). Optionally, one of the network devices may be responsible for interacting with the terminal device for radio resource control messages and for interacting with a core network control plane entity, so that the network device may be referred to as an MN, and the remaining radio access network devices may be referred to as SNs. The terminal device may maintain two Media Access Control (MAC) layer entities corresponding to the MN and the SN, respectively. For example, a plurality of carriers or cells may exist on a Uu interface link between the terminal device and the MN, and may be referred to as a primary serving cell (PCell) or a secondary serving cell (SCell), and a plurality of carriers or cells may exist on a Uu interface link between the terminal device and the SN, and may be referred to as a primary secondary cell (PSCell) and a secondary serving cell (SCell).
It should be understood that fig. 1 and 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 flowchart of a communication method provided in the present application, and the following describes a technical solution of an embodiment of the present application in detail with reference to fig. 3. Illustratively, the communication method 300 corresponding to fig. 3 may include:
operation 301: the terminal equipment receives the information of the first duration from the network equipment.
For example, the first duration may be terminal device granularity, that is, the network device configures one first duration for one 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 duration may include two time points, and the first time duration is an absolute value of a difference between the two time points; alternatively, the information of the first duration may include a duration, and the first duration is the duration.
For example, the first duration may be of a link granularity, that is, the network device configures one first duration for one link of the terminal device, the terminal device may configure one first duration for the Uu port link of the terminal device, and may also configure one first duration for the side link of the terminal device. For example, the information of the first duration may include four time points, where an absolute value of a difference between two time points is the first duration of the side link, and an absolute value of a difference between two time points is the first duration of the Uu port link; alternatively, the information of the first duration may include two durations, which are the first duration of the side link and the first duration of the Uu port link, respectively.
Optionally, the first duration may be carrier-granular, that is, the network device configures one first duration for one carrier, and the network device may further determine the first duration according to a sub-carrier spacing (SCS) of carriers 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 of the first durations 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 durations.
Optionally, the first duration may also be of bandwidth part (BWP) granularity, and the information of the first duration may refer to the above description, which is not described herein again.
Operation 301 is an optional operation, and for example, the terminal device stores the information of the first duration, for example, if a protocol or a standard specifies the information of the first duration, a device manufacturer may store the information of the first duration in the terminal device before the terminal device leaves a factory, or a network device may pre-configure the information of the first duration in the terminal device when the terminal device accesses a network, or the protocol or the standard specifies which algorithm determines the first duration, and the terminal device may determine the first duration information according to the algorithm, for example, the terminal device may determine the first duration information according to subcarrier interval information and/or capability of the UE, 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.
For example, the terminal device may determine the first data transmission time by monitoring Downlink Control Information (DCI) on a control channel of the second link, or an already configured data transmission resource grant (configured grant) of the terminal device.
For example, the first data transmission time may be determined by the terminal device based on a configured grant, for example, the first data transmission time is a starting time of a data transmission resource corresponding to the configured grant; the configurable grant may be an authorization that the terminal device may use without further authorization, and the configurable grant may be a configurable grant corresponding to a first data transmission resource that may be used to transmit the 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 starting time of a data transmission resource scheduled by the DCI. The DCI may be a DCI scrambled by a cell specific radio network temporary identifier (CS-RNTI), and the DCI may be caused by a terminal device requesting a network device for transmission resources for Power Headroom Report (PHR) reporting through a Scheduling Request (SR) or a Buffer Status Report (BSR), and exemplarily, the DCI is used for allocating the transmission resources for the PHR reporting.
The configured grant or the DCI may be for a certain carrier, that is, the carrier may be a carrier belonging to a Uu port link, or may also be a carrier belonging to a side link.
Optionally, 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.
Illustratively, the first link in fig. 3 is a direct-connection wireless communication link between the terminal device and another terminal device, the second link is a wireless communication link between the terminal device and the network device, and illustratively, the first link is a side 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 at which the PHR is determined latest, and the first time may be a time obtained by subtracting the first duration from the first data transmission time.
Optionally, the first time may be a time when the terminal device monitors the DCI, or the first time may be a preparation time of subtracting a Physical Uplink Shared Channel (PUSCH) from a first uplink symbol (symbol) transmitted at the first data transmission time.
Optionally, the first time may be referred to as a PHR bundling time, where the PHR bundling time may refer to a time when the terminal device starts determining various parameters included in the PHR, or may refer to a time when the terminal device starts generating the PHR, for example, a time when a power headroom report media access control element (PHR MAC CE) starts to be bundled.
Operation 304: the terminal equipment determines the resource allocation condition of the first link.
Illustratively, the first link is an edge link. For a clearer description of the method, the following will describe how the terminal device determines the resource allocation of the edge link, taking the terminal device including an edge link, where the edge link includes the first carrier as an example; the one side link may include multiple carriers, for example, the terminal device and other terminal devices communicate in a carrier aggregation manner, the side link between the terminal device and other terminal devices may include multiple carriers, and at this time, the resource allocation condition of each carrier may be determined by referring to the following method, which is not described herein again. When the terminal device includes multiple edge links, if the terminal device and multiple terminal devices perform unicast communication, multicast communication, or broadcast communication, multiple edge links may exist between the terminal device and other terminal devices, and the resource allocation condition of each edge link may be determined by referring to the following method, which is not described herein again.
The terminal device may include an edge link, the edge link 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, in this application, the "first carrier of the side link" and the "first carrier of the Uu port link" are used for example, in this application, the "first carrier of the side link" may be replaced with the "side link", and the "first carrier of the Uu port link" may be replaced with the "Uu port link", which is not described herein again.
Optionally, in this application, the "first carrier of the first link" and the "first carrier of the second link" are used for example, in this application, the "first carrier of the first link" may be replaced by the "first link", and the "first carrier of the second link" may be replaced by the "second link", which is not described herein again.
The terminal device may monitor the resource allocation on the first carrier: when monitoring that the first carrier has the resource allocation of the side link obtained through the first mode, the terminal equipment determines that the resource allocation of the side link with the first mode exists; monitoring the resource allocation of the edge link obtained through the first mode may include monitoring a configured edge link data transmission resource grant (configured grant), or monitoring an edge link data transmission resource grant sent to the network device, for example, monitoring a DCI configured with the first mode resource;
and when the first carrier has the resource allocation of the side link obtained through the second mode, the terminal equipment determines that the resource allocation of the side link in the second mode exists. Monitoring the resource allocation of the edge link obtained in the second mode may include monitoring that the terminal device perceives or competes for the edge link data transmission resource, for example, monitoring that the terminal device obtains the edge link data transmission resource in the second mode.
When the first carrier has the resource allocation of the side link obtained through the first mode and/or the second mode, the terminal device determines the resource allocation of the side link. When it is monitored that the first carrier has an existing configured uplink data transmission resource grant (configured grant) or DCI for allocating an uplink resource, the terminal device may determine that there is a resource allocation of a Uu port link.
Optionally, the first resource configuration mode includes: the network device configures edge link transmission resources for the terminal device, which may include obtaining the edge link resources through a first mode, and the second resource configuration mode includes: the terminal device selects the side link transmission resource, which may include obtaining the side link resource through the second mode; alternatively, the second resource configuration mode includes: the network device configures edge link transmission resources for the terminal device, which may include obtaining the edge link resources through a first mode, where the first resource configuration mode includes: the terminal device selects the side link transmission resource, which may include obtaining the side link resource through the second mode.

Optionally, considering whether carriers between the Uu port link and the side link can be shared, and whether powers between the first mode and the second mode of the Uu port link and the side link can be shared, the above-mentioned (r) to (c) can be divided into 8 possible cases as shown in table 4 to specifically describe the above-mentioned method for determining the power headroom report PHR, taking the Uu port link and the side link as an example,
table 4:
in an example, the Uu port link and the side link do not share a carrier, which may indicate that the same carrier may serve both the Uu port link and the side link, or may indicate that the same carrier may serve both the Uu port link and the side link. Optionally, the shared power of the Uu port link and the side link may be represented in power control, where a sum of the transmission power of the Uu port link and the transmission power of the side link is smaller than a fixed value, that is, when the transmission power of the side link is 0, the maximum transmission power of the Uu port link may reach the fixed value, and similarly, when the transmission power of the Uu port link is 0, the maximum transmission power of the side link may reach the fixed value. The shared power in table 4 can be understood by referring to the above explanation of the power sharing between the Uu port link and the side link, and is not described herein again. 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 and the bandwidth part (BWP) may be replaced with each other, 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, which indicates that the influence of the condition whether the Uu port link and the side link share the first carrier and the condition whether the Uu port link and the side link share the power between the first mode or the second mode is not considered; for example, cases (1) to (4) may be combined with cases (5) to (8), respectively, so as to indicate that the influence of the condition of whether the Uu port link and the side link share the first carrier is not considered; 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 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 the protocol stipulates one or more of the conditions (1) to (8), the table 4 may delete the rows where the rest of the conditions exist to form a new table, and the terminal device may not consider the rest of the conditions.
