Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a resource allocation method, device, and terminal. Background Art

[0002] Direct communication refers to a method in which adjacent terminals can transmit data over a short distance via a direct communication link (also called a sidelink or bypass link). The wireless interface corresponding to the sidelink link is called a direct communication interface (also called a sidelink interface or sidelink interface). Figure 1 As shown in FIG. 1 , UE (terminal) 1 can directly communicate with UE2 via Sidelink.

[0003] However, in the current direct communication interface LCP (Logical Channel Prioritization) process (i.e., the direct communication interface resource allocation process), the selection of the direct communication interface destination address (destination) or the direct communication interface Logical Channel (LCH) only considers factors such as whether there is available direct communication data and whether the logical channel restriction (LCH restriction) is met, without considering other factors. As a result, the direct communication interface destination or LCH selected by the terminal may be unable to transmit data, resulting in a waste of direct communication interface resources.

A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network.

According to the form and number of root antenna combinations, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or can be diversity transmission or precoding transmission or beamforming transmission, etc.

[0090] First, the content related to the scheme provided by the embodiments of the present application is introduced.

[0091] (1) Cellular network communication:

[0092] In cellular network communication, the terminal and the network side device transmit uplink or downlink data and control information through the Uu interface. For details, refer to Figure 3 .

[0093] (2) DRX mechanism of the Uu interface of the cellular communication system:

[0094] In a mobile communication system based on a shared channel, such as LTE, the transmission of uplink and downlink data is controlled by the base station (eNB) scheduler. When the scheduler determines to schedule a user, it will inform the terminal through the control channel to send or receive data on which resource. The terminal (UE) listens to the control channel, and when it detects the scheduling information containing itself, it completes the transmission (uplink) or reception (downlink) of data according to the indication on the control channel. In the active state, since the terminal does not know when the eNB will schedule it, a common working mode is that the terminal continuously listens to the control channel and analyzes each subframe containing its downlink scheduling control channel to determine whether it is scheduled. This working method can obtain high efficiency in the case that the terminal has a large amount of data and may be frequently scheduled. However, for some services, the arrival frequency of data is low, which leads to a small number of times of terminal scheduling. If the terminal still continuously listens to the control channel, it will undoubtedly increase its power consumption. In order to solve the power consumption problem, the cellular network communication system adopts the DRX working mode, in which the terminal periodically listens to the control channel, thereby achieving the purpose of power saving.

[0095] Basic principles of DRX:

[0096] The basic principles of DRX are as follows Figure 4As shown in the figure, On duration represents the time period during which the UE monitors the control channel, during which the RF channel is open and continuously monitors the control channel; except for the On duration, the UE is in Sleep state (also known as the inactive period or silent period), its RF link will be closed, and it will no longer monitor the control channel to save power. On Duration appears periodically according to the DRX Cycle in the figure, and the specific period is implemented by the eNB configuration. UE shall monitor PDCCH in the figure indicates that the UE will monitor the downlink control channel; Opportunity for DRX represents the other time except On duration.

[0097] The DRX mechanism in cellular networks takes into account the arrival pattern of data traffic, namely, the bursty arrival of data packets (which means that once a data packet arrives, a large number of packets arrive in a short period of time). To accommodate this traffic arrival pattern, the LTE DRX process uses multiple timers and integrates them with the Hybrid Automatic Repeat Request (HARQ) process to achieve better power conservation.

[0098] About DRX related timers:

[0099] 1) drx-on Duration Timer: The time during which the UE periodically wakes up to monitor the control channel, such as Figure 4 shown.

[0100] 2) Short DRX cycle timer: In order to better match the characteristics of data service arrival, the cellular network communication system supports the configuration of two DRX cycles: long cycle and short cycle. The onduration timer of the two cycles is the same, but the sleep time is different. In the short cycle, the sleep time is relatively shorter, and the UE can monitor the control channel again more quickly. The long cycle must be configured and is the initial state of the DRX process; the short cycle is optional. The short DRX cycle timer sets the duration of the short cycle. After the shortcycle timer expires, the UE will use the long cycle.

[0101] 3) drx-Inactivity Timer: When DRX is configured, this timer is started when the UE receives control signaling for an initial HARQ transmission within the time allowed to monitor the control channel (i.e., within the Active Time). The UE continuously monitors the control channel until the timer expires. If the UE receives control signaling for an initial HARQ transmission before the drx-Inactivity Timer expires, the drx-Inactivity Timer is terminated and restarted.

[0102] 4) HARQ RTT (Round Trip Timer): This timer is divided into drx-HARQ-RTT-Timer DL (downlink) and drx-HARQ-RTT-Timer UL (uplink). This timer allows the UE to avoid monitoring the control channel until the next retransmission, thereby achieving better power conservation. For example, the following example shows that this timer is enabled for the first symbol after the PUCCH (uplink control channel) transmission of the UE-related process. If the data in the corresponding HARQ process is unsuccessfully decoded after the previous HARQ transmission (for example, the UE returns a negative acknowledgement (NACK)), the UE starts the drx-Retransmission (retransmission) Timer DL after the DL HARQ RTT Timer expires. If the data in the corresponding HARQ process is successfully decoded after the previous HARQ transmission (for example, the UE returns an ACK), the UE does not start the drx-Retransmission (retransmission) Timer DL after the drx-HARQ-RTT-Timer DL timer expires. If only drx-HARQ-RTT-Timer DL is currently running, the UE does not monitor the control channel.

[0103] 5) HARQ retransmission timer: It is divided into drx-Retransmission Timer DL and drx-Retransmission Timer UL. The following behavior is used as an example. During the DL HARQ retransmission timer, the UE monitors control signaling and waits for the retransmission schedule of the corresponding HARQ process.

[0104] Definition of Active time under DRX:

[0105] The above process shows that if any of the On Duration Timer, HARQ Retransmission Timer, and Inactivity Timer is running, the UE will monitor the control channel. The time the UE monitors the control channel is also called the Active Time. In the LTE system, the Active Time is affected by factors other than the DRX timer. The UE Active Time includes the following:

[0106] 1) The running time of drx-on Duration Timer or drx-Inactivity Timer or drx-Retransmission Timer DL or drx-Retransmission Timer UL or ra-Contention Resolution Timer (random access contention resolution timer);

[0107] 2) The time the UE waits for the base station to send the PDCCH after sending the uplink scheduling request (SR);

[0108] 3) Non-contention random access: The time a UE waits for the PDCCH scheduled by the C-RNTI (Cell Radio Network Temporary Identity) after receiving the RAR (Random Access Response).

[0109] About onduration calculation under DRX:

[0110] For a short DRX cycle, the onduration calculation formula is as follows:

[0111] [(SFN×10)+subframe number]modulo(shortDRX-Cycle)=(drxStartOffset)modulo(shortDRX-Cycle);

[0112] For a long DRX cycle, the onduration calculation formula is as follows:

[0113] [(SFN×10)+subframe number]modulo(longDRX-Cycle)=drxStartOffset;

[0114] in:

[0115] SFN (System Frame Number): indicates the SFN number of the current wireless frame;

[0116] Subframe number: indicates the number of the current subframe;

[0117] shortDRX-Cycle: indicates a short DRX cycle;

[0118] longDRX-Cycle: indicates a long DRX cycle;

[0119] drxStartOffset: represents an offset value configured by RRC (Radio Resource Control) signaling.

[0120] modulo represents the modulo operation.

[0121] About the basic principles of direct communication interface DRX and DTX:

[0122] 1) For direct communication interface unicast communication, the granularity of direct communication interface DRX and DTX is: a combination of each direct communication interface source address and direct communication interface destination address.

[0123] 2) For direct communication interface broadcast or multicast communication, the granularity of sidelink DRX and DTX has not yet been determined. Possible granularities are: based on the PQI (ProSe QoS Identifier) ​​or PQI set of the direct communication interface logical channel.

[0124] Based on the above, embodiments of the present application provide a resource allocation method, apparatus, and terminal to address the resource waste problem in prior art resource allocation schemes for direct communication interfaces. The method, apparatus, and terminal are based on the same patent application concept. Since the principles for solving the problems are similar, the implementation of the method, apparatus, and terminal can refer to each other, and any repetitions will not be repeated.

[0131] This ensures that the selected direct communication interface target address is a direct communication interface target address that meets the conditions.

[0132] Further, optionally, after obtaining the direct communication interface target address that is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization, it also includes: selecting the target direct communication interface logical channel from the direct communication interface logical channel corresponding to the direct communication interface target address according to the second condition; wherein the second condition includes: the direct communication interface logical channel is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization.

[0133] In this way, it can be ensured that the DRX state and / or DTX state corresponding to the selected logical channel at the current moment will not be a silent period, thereby avoiding resource waste.

[0134] In an embodiment of the present application, obtaining a direct communication interface logical channel that is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization includes: obtaining a direct communication interface logical channel that is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization according to a first method; wherein the first method includes: determining the DRX configuration information corresponding to the direct communication interface logical channel according to the direct communication interface target address corresponding to the direct communication interface logical channel; determining whether the direct communication interface logical channel is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization according to the DRX configuration information; or determining the DRX configuration information corresponding to the direct communication interface logical channel according to the quality of service QoS parameter corresponding to the direct communication interface logical channel; determining whether the direct communication interface logical channel is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization according to the DRX configuration information.

[0135] The direct communication interface logical channel in the phrase "determining DRX configuration information corresponding to the direct communication interface logical channel based on a direct communication interface target address corresponding to the direct communication interface logical channel" may specifically be a logical channel on the current direct communication interface of the terminal. The direct communication interface logical channel in the phrase "determining DRX configuration information corresponding to the direct communication interface logical channel based on a Quality of Service (QoS) parameter corresponding to the direct communication interface logical channel" may specifically be a logical channel on the current direct communication interface of the terminal.

[0136] In an embodiment of the present application, the obtaining of the direct communication interface target address in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization includes: obtaining the direct communication interface target address in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization according to the second method; wherein the second method includes: determining the DRX configuration information corresponding to the direct communication interface target address according to the first address; determining whether the direct communication interface target address is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization according to the DRX configuration information; the first address includes the direct communication interface target address, or the direct communication interface source address and the direct communication interface target address. combination; or, determining, according to the direct communication interface logical channel corresponding to the direct communication interface target address, the QoS parameter corresponding to the direct communication interface logical channel; determining, according to the QoS parameter, the DRX configuration information corresponding to the QoS parameter; determining, according to the DRX configuration information, whether the direct communication interface logical channel is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization; if at least one direct communication interface logical channel corresponding to the direct communication interface target address is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization, then determining that the direct communication interface target address is in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link authorization.

[0137] The resource allocation method provided in the embodiment of the present application is further described below.

[0138] In response to the above technical problems, in order to achieve power saving of the direct communication interface, a DRX mechanism is introduced for the direct communication interface; the introduction of the DRX mechanism into the direct communication interface will have a certain impact on the resource allocation of the direct communication interface; an embodiment of the present application provides a resource allocation method, which can be specifically implemented as a method for resource allocation of a direct communication interface. Through this method, more efficient resource allocation can be achieved in the direct communication interface to avoid resource waste.

[0139] This solution mainly involves: when a direct communication terminal executes LCP (direct communication interface logical channel priority, that is, resource allocation) for a Sidelink (direct communication link) grant, only the direct communication interface destination (target address) and / or direct communication interface logical channel that is in Sidelink DRX (discontinuous reception) and / or DTX (discontinuous transmission) active time (activation time, that is, the time when the UE monitors the control channel) on the time domain resources corresponding to the Sidelink grant is considered.

[0140] Specifically:

[0141] 1. In the step of performing direct communication interface destination (hereinafter referred to as destination) selection in the LCP process, "only considering the destination in the sidelink DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant (corresponding to the direct communication interface target address in the direct communication link grant discontinuous transmission activation time on the time domain resources corresponding to the direct communication link grant obtained above)", the specific implementation method may be one or a combination of the following (corresponding to the direct communication interface target address in the direct communication link discontinuous transmission activation time on the time domain resources corresponding to the direct communication link grant obtained above according to the first condition):

[0142] (1) Add restrictions when selecting a destination: restrict the selected destination to be in the (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant;

[0143] (2) Adding restrictions when selecting a destination: When selecting a destination, only the direct communication interface logical channels corresponding to the destination that are in the (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant are considered.

[0144] 2. Optionally, in the step of selecting a direct communication interface logical channel in the selected destination during the LCP process, "only considering the direct communication interface logical channels in the sidelink DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant" can be specifically implemented as follows:

[0145] A restriction is added when selecting a direct communication interface logical channel within the selected destination: the selected direct communication interface logical channel is restricted to being in (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant. Corresponding to the second condition described above, a target direct communication interface logical channel is selected from the direct communication interface logical channels corresponding to the direct communication interface target address.

[0146] 3. For 1 or 2, the method for determining whether the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant (corresponding to the first method above) may be one of the following:

[0147] (1) Determining a DRX configuration (i.e., DRX configuration information) corresponding to the direct communication interface logical channel based on the destination corresponding to the direct communication interface logical channel, and then determining, based on the DRX configuration, whether the direct communication interface logical channel is in (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant.

[0148] (2) Determine the DRX configuration corresponding to the direct communication interface logical channel based on the QoS parameters (such as PQI) corresponding to the direct communication interface logical channel, and then determine whether the direct communication interface logical channel is in (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant based on the DRX configuration.

[0149] 4. For 1, the method for determining that “the destination is in DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant” (corresponding to the second method above) can be one of the following:

[0150] (1) Determining a DRX configuration corresponding to a destination based on a first address, and then determining whether the destination is in (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to a sidelink grant based on the DRX configuration. The first address includes the destination, or a combination of a direct communication interface source address and the destination.

[0151] (2) Determine, based on the direct communication interface logical channel corresponding to the destination, a QoS parameter (such as a PQI) corresponding to the direct communication interface logical channel, then determine, based on the QoS parameter, a DRX configuration corresponding to the QoS parameter, and then determine, based on the DRX configuration, whether the direct communication interface logical channel is in (Sidelink) DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant. If at least one direct communication interface logical channel corresponding to the destination is in the direct communication link discontinuous transmission active time on the time domain resources corresponding to the direct communication link grant, determine that the destination is in the direct communication link discontinuous transmission active time on the time domain resources corresponding to the direct communication link grant.

[0152] The following is an example of a resource allocation process (ie, LCP (Logical channel prioritization) process) of a direct communication interface provided in an embodiment of the present application.

[0153] Example 1:

[0154] Step 1: Select the direct communication interface logical channel;

[0155] This step is further divided into the following two processes:

[0156] Step 1.1: Select the direct communication interface destination address (destination);

[0157] In this step, when the terminal receives SCI (Sidelink Scheduling Information) for new data transmission, it first determines whether the corresponding destination is in DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant from the MAC (Media Access Control) CE (Control Element) corresponding to all communication types of the direct communication interface (including unicast, groupcast, and broadcast) and the direct communication interface logical channel that meets specific conditions and has the highest priority MAC CE or direct communication interface logical channel. The destination address corresponding to the highest priority MAC CE or direct communication interface logical channel is used as the selected direct communication interface destination address. The specific conditions that the direct communication interface logical channel needs to meet include:

[0158] (1) the direct communication interface logical channel has direct communication data available; and

[0159] (2) SBj>0 (SBj (sidelink Prioritized Bit Rate) is the number of tokens in the token bucket corresponding to the direct communication interface logical channel); and

[0160] (3) If the Sidelink grant is a CG (Configured Grant) of type 1, the direct communication interface logical channel needs to be configured with sl (Sidelink)-configured Grant Type1Allowed and the value of sl-configured Grant Type1 Allowed is set to true; and

[0161] (4) If the direct communication interface logical channel is configured with an sl-Allowed CG-List, the sl-Allowed CG-List must include the number of the Sidelink CG corresponding to the current Sidelink grant; and

[0162] (5) If the Sidelink grant corresponding to the SCI is not configured with PSFCH (Physical sidelink feedback channel), the sl-HARQ-Feedback Enabled corresponding to the direct communication interface logical channel needs to be set to disabled (not used).

[0163] If multiple target addresses meet the above conditions at the same time, the specific target address selected depends on the terminal implementation.

[0164] Specifically, the determination method of "the destination is in DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant" can be one of the following:

[0165] (1) Determining a DRX configuration corresponding to a destination based on a first address, and then determining whether the destination is in DRX and / or DTX active time on the time domain resources corresponding to a sidelink grant based on the DRX configuration. The first address includes the destination, or a combination of a direct communication interface source address and the destination.

[0166] (2) determining the QoS parameter (such as PQI) corresponding to the direct communication interface logical channel according to the direct communication interface logical channel corresponding to the destination, and then determining the DRX configuration corresponding to the QoS parameter according to the QoS parameter, and then determining whether the direct communication interface logical channel is in the DRX and / or DTX active time on the time domain resource corresponding to the Sidelink grant according to the DRX configuration; if at least one direct communication interface logical channel corresponding to the destination is in the direct communication link discontinuous transmission active time on the time domain resource corresponding to the direct communication link grant, it is determined that the destination is in the direct communication link discontinuous transmission active time on the time domain resource corresponding to the direct communication link grant.

[0167] Step 1.2: selecting a direct communication interface logical channel from the direct communication interface logical channels corresponding to the target address selected in step 1.1, which satisfies the following conditions:

[0168] (1) the direct communication interface logical channel is in the DRX and / or DTX active time on the time domain resource corresponding to the Sidelink grant (further limited, only when the cast type corresponding to the Sidelink grant is unicast, this step does not need to be performed, if the cast type corresponding to the Sidelink grant is broadcast and / or groupcast, this step needs to be performed); and,

[0169] (2) the direct communication interface logical channel has available direct communication data; and,

[0170] (3) if the Sidelink grant is a type 1 CG (Configured Grant, pre-configured grant), the direct communication interface logical channel needs to be configured with sl-configured Grant Type1Allowed and the value of sl-configured Grant Type1 Allowed is set to true; and,

[0171] (4) if the direct communication interface logical channel is configured with sl-Allowed CG-List, the sl-Allowed CG-List needs to contain the number of the Sidelink CG corresponding to the current Sidelink grant; and,

[0172] (5) If the Sidelink grant corresponding to the SCI is not configured with PSFCH, the sl-HARQ-Feedback Enabled corresponding to the direct communication interface logical channel needs to be set to disabled; and

[0173] 1) If the sidelink grant corresponding to the SCI is configured with PSFCH:

[0174] If the sl-HARQ-Feedback Enabled corresponding to the direct communication interface logical channel with the highest priority that meets the above conditions (the conditions listed before this condition) is enabled, the direct communication interface logical channel to be selected must also meet the condition that its sl-HARQ-Feedback Enabled is enabled; or,

[0175] If the sl-HARQ-Feedback Enabled corresponding to the highest priority direct communication interface logical channel that meets the above conditions (the conditions listed before this condition) is disabled, then the direct communication interface logical channel to be selected must also meet the condition that its sl-HARQ-Feedback Enabled is disabled.

[0176] 2) Otherwise (the Sidelink grant corresponding to the SCI is not configured with PSFCH):

[0177] The sl-HARQ-Feedback Enabled value of the direct communication interface logical channel needs to be set to disabled.

[0178] Specifically, the determination method of "the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant" may be one of the following:

[0179] (1) Determine a DRX configuration corresponding to the direct communication interface logical channel according to a destination corresponding to the direct communication interface logical channel, and then determine, according to the DRX configuration, whether the direct communication interface logical channel is in a DRX and / or DTX active time on the time domain resource corresponding to the Sidelink Grant.

[0180] (2) Determine the DRX configuration corresponding to the direct communication interface logical channel according to the QoS parameter (such as PQI) corresponding to the direct communication interface logical channel, and then determine whether the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant according to the DRX configuration.

[0181] Step 2: Allocate resources for the direct communication interface logical channel selected in step 1 (in this example);

[0182] The specific process is as follows:

[0183] Step 2.1: Allocate resources for the sPBR (Direct Communication Interface Priority Bit Rate) of the direct communication interface logical channels selected in Step 1 with SBj > 0, in descending order of their priority. If the sPBR corresponding to a direct communication interface logical channel is set to infinite, the MAC entity allocates resources for all data on that direct communication interface logical channel.

[0184] Step 2.2: According to step 2.1, update the SBj corresponding to each direct communication interface logical channel.

[0185] Step 2.3: If resources remain, allocate resources sequentially according to the priority order of all direct communication interface logical channels determined in step 1 until all data on the direct communication interface logical channels has been allocated resources or the resources are exhausted. Direct communication interface logical channels with the same priority should be treated equally.

[0186] Example 2:

[0187] Step 1: Select the direct communication interface logical channel;

[0188] This step is further divided into the following two processes:

[0189] Step 1.1: Select the destination address for the direct communication interface

[0190] In this step, when the terminal receives an SCI for new data transmission, it first determines the highest-priority MAC CE or direct communication interface logical channel from among the MAC CEs corresponding to all communication types (including unicast, groupcast, and broadcast) of the direct communication interface and the direct communication interface logical channels that meet specific conditions. The target address corresponding to the highest-priority MAC CE or direct communication interface logical channel is used as the selected direct communication interface target address. The specific conditions that the direct communication interface logical channel needs to meet include:

[0191] (1) The direct communication interface logical channel is in DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant;

[0192] (2) the direct communication interface logical channel has direct communication data available; and

[0193] (3) SBj>0 (SBj (sidelink Prioritized Bit Rate) is the number of tokens in the token bucket corresponding to the direct communication interface logical channel); and

[0194] (4) If the Sidelink Grant is a type 1 CG (Configured Grant), the direct communication interface logical channel needs to be configured with sl-configured Grant Type1Allowed and the value of sl-configured Grant Type1Allowed is set to true; and

[0195] (5) If the direct communication interface logical channel is configured with an sl-Allowed CG-List, the sl-AllowedCG-List needs to include the number of the Sidelink CG corresponding to the current Sidelink grant; and

[0196] (6) If the Sidelink grant corresponding to the SCI is not configured with PSFCH, the sl-HARQ-Feedback Enabled corresponding to the direct communication interface logical channel needs to be set to disabled.

[0197] If multiple target addresses meet the above conditions at the same time, the specific target address selected depends on the terminal implementation.

[0198] Specifically, the determination method of "the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resources corresponding to the Sidelink grant" may be one of the following:

[0199] (1) Determine a DRX configuration corresponding to the direct communication interface logical channel according to a destination corresponding to the direct communication interface logical channel, and then determine, according to the DRX configuration, whether the direct communication interface logical channel is in a DRX and / or DTX active time on the time domain resource corresponding to the Sidelink Grant.

[0200] (2) Determine the DRX configuration corresponding to the direct communication interface logical channel according to the QoS parameter (such as PQI) corresponding to the direct communication interface logical channel, and then determine whether the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resources corresponding to the sidelink grant according to the DRX configuration.

[0201] Step 1.2: Select a direct communication interface logical channel that meets the following conditions from the direct communication interface logical channels corresponding to the target address selected in step 1.1:

[0202] (1) The direct communication interface logical channel is in DRX and / or DTX active time on the time domain resource corresponding to the sidelink grant (it can be further specified that this step is not required only when the cast type corresponding to the sidelink grant is unicast, and is required only when the cast type corresponding to the sidelink grant is broadcast and / or multicast); and

[0203] (2) the direct communication interface logical channel has direct communication data available; and

[0204] (3) If the Sidelink Grant is a CG (Configured Grant) of type 1, the direct communication interface logical channel needs to be configured with sl-configured Grant Type1Allowed and the value of sl-configured Grant Type1 Allowed is set to true; and

[0205] (4) If the direct communication interface logical channel is configured with an sl-Allowed CG-List, the sl-AllowedCG-List needs to include the number of the Sidelink CG corresponding to the current Sidelink grant; and

[0206] (5) If the Sidelink grant corresponding to the SCI is not configured with PSFCH, the sl-HARQ-Feedback Enabled corresponding to the direct communication interface logical channel needs to be set to disabled; and

[0207] 1) If the sidelink grant corresponding to the SCI is configured with PSFCH:

[0208] If the sl-HARQ-Feedback Enabled corresponding to the highest priority direct communication interface logical channel satisfying the above conditions (several conditions listed before this condition) is enabled, the direct communication interface logical channel to be selected also needs to satisfy the condition that its sl-HARQ-Feedback Enabled is enabled; or,

[0209] If the sl-HARQ-Feedback Enabled corresponding to the highest priority direct communication interface logical channel satisfying the above conditions (several conditions listed before this condition) is disabled, the direct communication interface logical channel to be selected also needs to satisfy the condition that its sl-HARQ-Feedback Enabled is disabled.

[0210] 2) Otherwise (SCI corresponding Sidelink grant is not configured with PSFCH):

[0211] The sl-HARQ-Feedback Enabled of the direct communication interface logical channel needs to be set to disabled.

[0212] Specifically, the determination method of the direct communication interface logical channel being in DRX and / or DTX active time on the time domain resource corresponding to the Sidelink grant can be one of the following:

[0213] (1) According to the destination corresponding to the direct communication interface logical channel to determine the DRX configuration corresponding to the direct communication interface logical channel, and then according to the DRX configuration to determine whether the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resource corresponding to the Sidelink grant.

[0214] (2) According to the QoS parameter (such as PQI) corresponding to the direct communication interface logical channel to determine the DRX configuration corresponding to the direct communication interface logical channel, and then according to the DRX configuration to determine whether the direct communication interface logical channel is in DRX and / or DTX active time on the time domain resource corresponding to the Sidelink grant.

[0215] Step 2: Resource allocation is performed for the direct communication interface logical channel selected in step 1 (in this example);

[0216] The specific process is as follows:

[0217] Step 2.1: Allocate resources for the sPBRs of the direct communication interface logical channels selected in Step 1 with SBj > 0, in descending order of their priority. If the sPBR corresponding to a direct communication interface logical channel is set to infinite, the MAC entity allocates resources for all data on that direct communication interface logical channel.

[0218] Step 2.2: According to step 2.1, update the SBj corresponding to each direct communication interface logical channel.

[0219] Step 2.3: If resources remain, allocate resources sequentially according to the priority order of all direct communication interface logical channels determined in step 1 until all data on the direct communication interface logical channels has been allocated resources or the resources are exhausted. Direct communication interface logical channels with the same priority should be treated equally.

[0220] In summary, the method for allocating resources on a direct communication interface provided by the embodiment of the present application can achieve more efficient resource allocation on a direct communication interface and avoid resource waste.
