Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority from Chinese Patent Application No. 202010038446.9, filed in China on January 14, 2020, the entire contents of which are incorporated herein by reference. The present invention relates to the technical field of communications, and in particular to a resource determination method and a communications device. [Background technology]

[0002] Sidelink (direct link or sidelink) terminals can communicate with other terminals in Sidelink, and typically these terminals are vehicles, roadside units (RSUs), mobile phones, etc. that support Sidelink technology.

[0003] A user's sidelink transmission (sending or receiving) is based on the timing of a selected synchronization reference source, also called a synchronization reference or timing reference, which may be a base station, a Global Navigation Satellite System (GNSS), or the timing used for its own local clock or the timing used for other devices. Sidelink resources may be numbered based on the sidelink timing, in which case the sidelink frame number is called the direct frame number (DFN), and may include the following scenarios:

[0004] In one scenario, a control node on carrier 1 schedules a user for a sidelink transmission on carrier 2, and the user uses the timing of the control node as the sidelink timing for its sidelink transmission on carrier 2.

[0005] In another scenario, a control node operating on carrier 1 schedules a user for sidelink transmission on carrier 2, and the user uses another timing, e.g., GNSS timing, as the sidelink timing for its sidelink transmission on carrier 2. In this case, the Uu timing and the sidelink timing may not be aligned.

[0006] Additionally, the subcarrier spacing (SCS) of sidelink and Uu may differ, resulting in different timing accuracy.

[0007] In order to improve the reliability and resource utilization of sidelink data transmission, a hybrid automatic repeat reQuest (HARQ) feedback mechanism is also introduced in sidelink technology. When a user receives sidelink data (sidelink data is transmitted on a physical sidelink shared channel PSSCH scheduled by sidelink control information SCI, and SCI is transmitted on a physical sidelink control channel PSCCH and / or PSSCH), the sidelink can indicate whether the sidelink transmission is successful or unsuccessful by feeding back sidelink HARQ-ACK information, which is transmitted on a physical sidelink feedback channel (PSFCH) resource.

[0008] A sidelink data packet may be transmitted between a control node and a terminal (in this case, the control node operates in the sidelink), or may be transmitted in the sidelink between terminals. In the latter case, the control node may not directly obtain whether the transmission of the sidelink data packet is successful, and the user transmits sidelink HARQ ACK information (e.g., sidelink ACK / NACK) to the control node, and then the control node can determine whether the sidelink transmission is successful. A terminal that transmits sidelink HARQ-ACK information corresponding to a certain sidelink transmission to the control node is a transmitting terminal that transmits this sidelink transmission. To ensure the transmission of sidelink HARQ-ACK information, the control node needs to allocate physical uplink control channel (PUCCH) / physical uplink shared channel (PUSCH) resources to the terminal.

[0009] However, due to the possible difference between Sidelink and Uu timing and / or different timing accuracy, there may be a discrepancy or ambiguity between the user and the control node regarding the location of Sidelink transmission resources / PSFCH / PUCCH / PUSCH resources. Summary of the Invention [Problem to be solved by the invention]

[0010] The embodiments of the present invention provide a resource determination method and a communication device to solve the problem in the prior art that the terminal and the control node may have different understandings of uplink channel resources. [Means for solving the problem]

[0021] In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and are not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without any creative efforts shall fall within the protection scope of the present invention.

[0022] In the embodiments of the present invention, the use of terms such as "exemplary" or "for example" is intended to indicate an example, illustration, or explanation. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Strictly speaking, terms such as "exemplary" or "for example" are used to present the relevant concept in a concrete manner.

[0023] The resource determination method provided in the embodiment of the present invention is applicable to both terminals and control nodes. Here, the terminal may be a mobile phone, a tablet computer, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a wearable device, an in-vehicle device, or a personal digital assistant (PDA), etc. It should be noted that the embodiment of the present invention does not limit the specific type of the terminal. The control node is a base station or some Integrated Access Backhaul (IAB) nodes. In the sidelink, the control node may be a terminal, a Road Side Unit (RSU), a base station, or other network mechanisms similar to RSU or IAB, and therefore some control nodes may have sidelink and Uu links at the same time. The base station may be a commonly used base station, an evolved node base station (eNB), a network side device in a 5G system (e.g., a next generation node base station (gNB) or a transmission and reception point (TRP)), or a device such as a cell.

[0024] It should be noted that the meanings of Uu transmission, Uu SCS, Uu link, and Uu resource described in the embodiments of the present invention are uplink transmission and / or downlink transmission between a terminal and a base station, uplink SCS and / or downlink SCS between a terminal and a base station, uplink and / or downlink between a terminal and a base station, uplink resources and / or downlink resources between a terminal and a base station, etc.

[0025] Scheduling by the control node for the terminal includes Inter-RAT sidelink scheduling and intra-RAT sidelink scheduling. For example, if the control node is an LTE base station, it can schedule the NR sidelink (this case is called Inter-RAT sidelink scheduling) or the LTE sidelink (this case is called intra-RAT sidelink scheduling). If the control node is a 5G or later version base station, it can schedule the NR sidelink (this case is called intra-RAT sidelink scheduling) or the LTE sidelink (this case is called Inter-RAT sidelink scheduling).

[0026] As shown in FIG. 1, an embodiment of the present invention includes: Time Interval TIFF0007617116000025.tif7161 and the first time domain position of the physical sidelink feedback channel PSFCH TIFF0007617116000026.tif7161 or time interval TIFF0007617116000027.tif7161 and the second time domain position of PSFCH determining 101 a time domain resource for a target uplink channel based on the time interval; TIFF0007617116000029.tif7161 is the time interval between the PSFCH and the target uplink channel, and the time domain resource of the target uplink channel is It is the A-th time domain resource within the time range of TIFF0007617116000030.tif7161, and It is the A-th time domain resource in the time range of TIFF0007617116000031.tif7161, and It is the A-th time domain resource that overlaps with TIFF0007617116000032.tif7161; and It is the A-th time domain resource that overlaps with TIFF0007617116000033.tif7161; and Also called the A-th time-domain resource after the time-domain resource corresponding to TIFF0007617116000034.tif7161, It is the A-th time domain resource after TIFF0007617116000035.tif7161, and Also called the A-th time-domain resource after the time-domain resource corresponding to TIFF0007617116000036.tif7161, It is the A-th time domain resource after TIFF0007617116000037.tif7161, and A resource determination method is provided, where A is an integer equal to or greater than 1.

[0027] In an embodiment of the present invention, the time domain resource of the target uplink channel is: The A-th time domain resource in the time range of TIFF0007617116000038.tif7161, or The A-th time-domain resource that overlaps with TIFF0007617116000039.tif7161, or If it is the Ath time domain resource after TIFF0007617116000040.tif7161, the terminal and the control node can agree on the understanding of the time domain resource of the target uplink channel based on the sidelink timing. The time domain resource of the target uplink channel is The A-th time domain resource in the time range of TIFF0007617116000041.tif7161, or The A-th time-domain resource that overlaps with TIFF0007617116000042.tif7161, or If it is the Ath time domain resource after TIFF0007617116000043.tif7161, the terminal and the control node can agree on the understanding of the time domain resource of the target uplink channel based on Uu timing.

[0028] In step 101, for the terminal and the control node, a time interval TIFF0007617116000044.tif7161 may be a pre-arranged value. For the terminal, the time interval TIFF0007617116000045.tif7161 may be set by an upper layer, or may be set by a base station through downlink control information DCI, and is not specifically limited herein. The target uplink channel includes a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH.

[0029] Optionally, the Ath time domain resource may specifically be the Ath time domain resource or the Ath available time domain resource. For example, The first time domain resource (assuming A=1) in the time range of TIFF0007617116000046.tif7161 is The first time-domain resource in the time range of TIFF0007617116000047.tif7161, or This is the first available time domain resource in the time range of TIFF0007617116000048.tif7161 ( If the first time domain resource in the time range of TIFF0007617116000049.tif7161 is not available, but the second time domain resource is available, The second time domain resource in the time range of TIFF0007617116000050.tif7161 becomes the first available time domain resource above.)

[0030] for example, The 15 kHz slot corresponding to TIFF0007617116000051.tif7161 corresponds to two 30 kHz slots, where A=the first time domain resource is: This represents the first 30 kHz slot within the 15 kHz slot corresponding to TIFF0007617116000052.tif7161.

[0031] for example, The 15 kHz slot corresponding to TIFF0007617116000053.tif7161 corresponds to two 30 kHz slots, of which the first slot is used for downlink and the second slot is used for uplink, in this case A=the first available time domain resource. This represents the first UL slot available for a 30 kHz uplink within the 15 kHz slot corresponding to TIFF0007617116000054.tif7161.

[0032] It should be noted that the terminal and the control node each determine based on at least one of the downlink control information DCI, the PSCCH configuration, the PSSCH configuration, and the PSFCH configuration. TIFF0007617116000055.tif7161 can be determined. TIFF0007617116000056.tif7161 is the reception or transmission time of the PSFCH, for example, the start of the Sidelink slot in which the PSFCH is received or transmitted.

[0033] In one embodiment, the time domain resource may be a slot, e.g. The Ath slot after TIFF0007617116000057.tif7161, or The Ath slot after the Sidelink slot corresponding to TIFF0007617116000058.tif7161, or It may be the A-th slot after the Uu slot corresponding to TIFF0007617116000059.tif7161.

[0034] Optionally, the above-mentioned "after" refers to the beginning of a time domain resource, for example, the beginning of a slot, being after the corresponding time range.

[0035] Optionally, the target uplink channel is used to transmit Sidelink Hybrid Automatic Repeat Request Response (HARQ-ACK) information.

[0036] For example, a resource of one target uplink channel may be associated with one or more (Physical Sidelink Feedback Channels) PSFCHs, and the terminal performs certain processing on the Sidelink HARQ-ACK information obtained from the PSFCHs associated therewith and then transmits it to the control node on the target uplink channel.

[0037] The HARQ-ACK information or other feedback information of the Uu link may be multiplexed into the target uplink channel, which is not specifically limited here.

[0038] Optionally, the first time domain position of the PSFCH is a time domain position of the PSFCH determined based on Sidelink timing, and the second time domain position of the PSFCH is a time domain position of the PSFCH determined based on Uu timing.

[0039] It should be noted that the time offset between Sidelink timing and Uu timing may or may not be zero. The Subcarrier Spacing (SCS) of Sidelink and the Subcarrier Spacing of Uu may be the same or different. Therefore, the timing accuracy may be the same or different.

[0040] In one alternative embodiment, when there is a timing offset between Sidelink timing and Uu timing, the method includes: Time domain location of downlink control information DCI TIFF0007617116000060.tif7161, the time interval between a DCI and a Sidelink resource indicated by said DCI TIFF0007617116000061.tif7161, time interval TIFF0007617116000062.tif7161, and a timing offset between the Sidelink timing and the Uu timing. determining a time interval TIFF0007617116000063.tif7161; TIFF0007617116000064.tif7161 is the time interval between a sidelink resource and a PSFCH corresponding to the sidelink resource, or the time interval between a sidelink resource and a PSFCH corresponding to the target uplink channel. For example,

number

[0041] That is, the first time domain position TIFF0007617116000069.tif7161 is the time domain location of the downlink control information (DCI) TIFF0007617116000070.tif7161, the time interval between a DCI and a Sidelink resource indicated by said DCI TIFF0007617116000071.tif7161, time interval TIFF0007617116000072.tif7161, and a timing offset between the Sidelink timing and the Uu timing.

[0042] Alternatively, if there is a timing offset between the Sidelink timing and the Uu timing, the method further comprises: TIFF0007617116000073.tif7161, and the timing offset between the Sidelink timing and the Uu timing. The method further includes determining TIFF0007617116000074.tif7161. For example,

number

[0043] That is, the first time domain position TIFF0007617116000076.tif7161 is the second time domain position of PSFCH TIFF0007617116000077.tif7161, and the timing offset between the Sidelink timing and the Uu timing.

[0044] Since the value of the timing offset may be an integer or a non-integer, when the value of the timing offset is a non-integer, the value of offset in the above formula is, for example, a value corresponding to the timing offset after rounding up, e.g., offset=ceil(timing offset). As another example, the value of offset is a value corresponding to the timing offset after rounding down, e.g., offset=floor(timing offset). Specifically, in one embodiment, TIFF0007617116000078.tif7161 is the time when the terminal received the DCI minus 1 / 2TA (TA is the amount of time advance correlation, e.g., Timing Advance).

[0045] In one embodiment, TIFF0007617116000079.tif7161 is the time interval between a DCI and the first sidelink resource indicated by the DCI. TIFF0007617116000080.tif7161 is a time interval between a first sidelink resource and a PSFCH corresponding to the first sidelink resource. TIFF0007617116000081.tif7161 is the time interval between the first sidelink resource and the PSFCH corresponding to the target uplink channel. TIFF0007617116000082.tif7161 may be the time interval between the PSFCH corresponding to the first sidelink resource and the last sidelink resource.

[0046] Specifically, assuming that B sidelink resources are scheduled by one DCI, or B sidelink resources are included in one sidelink configuration grant resource, and each sidelink resource corresponds to one PSFCH occasion, the PSFCH occasions corresponding to different sidelink resources may be the same PSFCH occasion, but may also be different PSFCH occasions, and these occasions may correspond to the same target uplink channel. TIFF0007617116000083.tif7161 is the time interval between the PSFCH timing corresponding to the first sidelink resource and the Bth sidelink resource.

[0047] It should be noted that the start time of the first Sidelink transmission is The point is that it is after the first sidelink time domain resource (e.g., sidelink slot) of TIFF0007617116000084.tif7161.

[0048] As an alternative embodiment, when there is no timing offset between the Sidelink timing and the Uu timing (i.e., the timing offset is 0 or the Sidelink timing and the Uu timing are aligned), the method includes: Time domain location of downlink control information DCI TIFF0007617116000085.tif7161, the time interval between a DCI and a Sidelink resource indicated by said DCI TIFF0007617116000086.tif7161, and time interval TIFF0007617116000087.tif7161 based on at least one of the first time domain position of the PSFCH determining a time interval TIFF0007617116000088.tif7161; TIFF0007617116000089.tif7161 is the time interval between a sidelink resource and a PSFCH corresponding to the sidelink resource, or the time interval between a sidelink resource and a PSFCH corresponding to the target uplink channel. For example,

number

[0049] That is, the first time domain position TIFF0007617116000094.tif7161 is the time domain location of the downlink control information (DCI) TIFF0007617116000095.tif7161, the time interval between a DCI and a Sidelink resource indicated by said DCI TIFF0007617116000096.tif7161, and time interval Related to at least one of TIFF0007617116000097.tif7161.

[0050] Alternatively, if there is no timing offset between the Sidelink timing and the Uu timing (i.e., the timing offset is 0 or the Sidelink timing and the Uu timing are aligned), the method may include: Second time domain position of PSFCH First time domain position of PSFCH based on TIFF0007617116000098.tif7161 The method further includes determining TIFF0007617116000099.tif7161. For example,

number

[0051] That is, the first time domain position TIFF0007617116000101.tif7161 is the second time domain position of PSFCH Related to TIFF0007617116000102.tif7161.

[0052] Specifically, in one embodiment, TIFF0007617116000103.tif7161 is the time when the terminal receives the DCI minus 1 / 2TA (TA is the amount of time advance correlation, e.g., timing advance). In one embodiment, the start time of the first sidelink transmission is This is after the first sidelink time domain resource (e.g., sidelink slot) of TIFF0007617116000104.tif7161.

[0053] What needs to be explained is the above At the beginning or end of the time domain resource where TIFF0007617116000105.tif7161 is located, one possibility of the time domain resource is a Uu slot or a Sidelink slot, and preferably, the slot resource is a Sidelink slot.

[0054] Selectively, TIFF0007617116000106.tif7161 is the time interval between the DCI and the first PSSCH and PSCCH resource indicated by the DCI, or TIFF0007617116000107.tif7161 is the time interval between the DCI and the first PSSCH resource indicated by the DCI, or TIFF0007617116000108.tif7161 is the time interval between DCI and the first PSCCH resource indicated by the DCI.

[0055] specifically, TIFF0007617116000109.tif7161 is the time interval between the DCI and the first Sidelink transmission indicated by the DCI, or TIFF0007617116000110.tif7161 is the time interval between the first sidelink transmission and the PSFCH corresponding to the first sidelink transmission. TIFF0007617116000111.tif7161 is the time interval between the first sidelink resource and the PSFCH corresponding to the target uplink channel. TIFF0007617116000112.tif7161 may be the time interval between the PSFCH corresponding to the first sidelink resource and the last sidelink resource.

[0056] Specifically, assuming that B sidelink resources are scheduled by one DCI, or B sidelink resources are included in one sidelink configuration grant resource, and each sidelink resource corresponds to one PSFCH occasion, the PSFCH occasions corresponding to different sidelink resources may be the same PSFCH occasion, but may also be different PSFCH occasions, and these occasions may correspond to the same target uplink channel. TIFF0007617116000113.tif7161 is the time interval between the PSFCH timing corresponding to the first sidelink resource and the Bth sidelink resource.

[0057] As another alternative embodiment, the offset is determined based on a sidelink subcarrier spacing or an uplink subcarrier spacing. Preferably, the offset is determined based on an uplink subcarrier spacing.

[0058] As another alternative embodiment, TIFF0007617116000114.tif7161 is determined based on the sidelink subcarrier spacing or is determined based on the uplink subcarrier spacing.

[0059] As yet another alternative embodiment, the gap is determined based on a sidelink subcarrier spacing or based on an uplink subcarrier spacing.

[0060] Optionally, in some special cases, for example, N sidelink transmissions all correspond to the same PSFCH time domain resource, or there is only one PSFCH time domain resource that can correspond to N sidelink transmissions before the target uplink channel, and the number of sidelink transmissions scheduled or configured is N, the method includes: The method further includes determining the gap based on a period N of a PSFCH and an interval K between a PSFCH and a corresponding physical sidelink shared channel PSSCH. That is, when the number of sidelink transmissions scheduled by a control node and the period of a PSFCH are the same, or when the number of sidelink transmissions configured and the period of a PSFCH are the same,

number

[0061] It should be noted that in one embodiment, the granularity of K and N is a logical slot (e.g., a Sidelink slot); The granularity of TIFF0007617116000116.tif7161 is the physical slot. Therefore, the actual distance between K sidelink slots may be greater than the time length of K slots, and the actual distance between N sidelink slots may be greater than the time length of N slots.

[0062] As another optional embodiment, the Ath time domain resource includes the Ath Sidelink time domain resource or the Ath Uu time domain resource. The Ath Uu time domain resource is the Ath uplink time domain resource.

[0063] Optionally, the uplink time domain resource is the resource available for transmission within the uplink resource.

[0064] For example, the first slot that satisfies any one of the above conditions is a downlink slot, which cannot be used for PUCCH transmission and must be deferred to the nearest available slot for uplink transmission.

[0065] What needs to be explained is the above TIFF0007617116000117.tif7161, TIFF0007617116000118.tif7161, TIFF0007617116000119.tif7161, TIFF0007617116000120.tif7161, TIFF0007617116000121.tif7161, TIFF0007617116000122.tif7161, TIFF0007617116000123.tif7161, the subcarrier intervals of parameters such as offset, N, and K may be the same or different, or the above parameters may be logical time or physical time. Therefore, in the specific determination process of the formula described in the above embodiment of the present invention, SCS conversion and / or integrated conversion to logical time or physical time may be required, but is not specifically limited here.

[0066] The resource determination method provided in the embodiments of the present invention will be described below with reference to several embodiments and drawings. It should be noted that in the following embodiments, all sidelink resources configured by DCI or higher layers correspond to the same PSFCH occasion (or time domain resource) as an example. When different resources correspond to different PSFCH occasions, the implementation method is similar, but: TIFF0007617116000124.tif7161 may need to be recalculated, for example, as the time interval between the first sidelink resource and the PSFCH time corresponding to the target uplink channel, and optionally, the PSFCH time corresponding to the target uplink channel is the PSFCH time corresponding to the last sidelink resource.

[0067] It should also be noted that in Figures 2 to 7, the shaded areas are the PSFCH.

[0068] Example 1 There is a timing offset between the Sidelink timing and the Uu timing.

[0069] Assume that offset=0.5 Sidelink slots=0.5 UL slots, two Sidelink transmissions are scheduled by the DCI, and K=N=2, and uplink subcarrier spacing (UL SCS)=sidelink subcarrier spacing (SCS)=30 kHz.

[0070] According to the base station timing, the slot corresponding to y2=2 (30 kHz slot) is slot 1, while according to the sidelink timing, the slot corresponding to y2=2 is slot 1'. From FIG. 2, it can be seen that the positions of slot 1 and slot 1' are different. Since the terminal actually considers that the transmission of PUCCH must be after slot 1', and the PUCCH resource is a Uu resource, the PUCCH resource actually applied to feedback the sidelink HARQ-ACK information is An available Uu or UL slot that overlaps with and follows slot 1', or The next available Uu or UL slot after slot 1', or

[0071] For example, the PUCCH resource actually applied is the PUCCH resource on slot 2 shown in FIG. Assume that TIFF0007617116000127.tif7161 is the beginning of the slot in which the PSFCH is located, and therefore TIFF0007617116000128.tif7161 corresponds to slot 1 in Figure 2, TIFF0007617116000129.tif7161 corresponds to slot 2 in Figure 2. If TIFF0007617116000130.tif7161 is defined as the end of the slot in which the PSFCH is located, TIFF0007617116000131.tif7161 and The slot corresponding to TIFF0007617116000132.tif7161 will be adjusted accordingly, e.g. moved backwards.

[0072] Example 2 There is a timing offset between the Sidelink timing and the Uu timing.

[0073] Assume that offset=0.5 Sidelink slots=0.25 UL slots, two Sidelink transmissions are scheduled by the DCI, and K=N=2, uplink subcarrier spacing (UL SCS)=15 kHz, and sidelink subcarrier spacing (Sidelink SCS)=30 kHz.

[0074] According to the base station timing, the slot corresponding to y2=1 (15 kHz slot) is slot 1, while according to the sidelink timing, the slot corresponding to y2=1 is slot 1'. From FIG. 3, it can be seen that the positions of slot 1 and slot 1' are different. Therefore, the PUCCH resource actually applied to feedback of sidelink HARQ-ACK information is: An available Uu or UL slot that overlaps with and follows slot 1', or The next available Uu or UL slot after slot 1', or

[0075] For example, the PUCCH resource actually applied is the PUCCH resource on slot 2 shown in FIG. Assume that TIFF0007617116000143.tif7161 is the beginning of the slot in which the PSFCH is located, and therefore TIFF0007617116000144.tif7161 corresponds to the UL SCS slot which corresponds to slot 1 in FIG. If TIFF0007617116000145.tif7161 is defined as the end of the slot in which the PSFCH is located, The slot corresponding to TIFF0007617116000146.tif7161 is adjusted accordingly, e.g. moved backwards.

[0076] Example 3 There is a timing offset between the Sidelink timing and the Uu timing.

[0077] Assume offset=0.75, Sidelink slots=1.5 UL slots, two Sidelink transmissions are scheduled by DCI, and K=N=2, Uplink subcarrier spacing (UL SCS)=30 kHz, and Sidelink subcarrier spacing (Sidelink SCS)=15 kHz.

[0078] According to the base station timing, the slot corresponding to y2=4 (30 kHz) is slot 1, while according to the sidelink timing, the slot corresponding to y2=4 is slot 1'. From FIG. 4, it can be seen that the positions of slot 1 and slot 1' are different. Therefore, the PUCCH resource actually applied to feedback of sidelink HARQ-ACK information is: An available Uu or UL slot that overlaps with and follows slot 1', or The next available Uu or UL slot after slot 1', or

[0079] For example, the PUCCH resource actually applied is the PUCCH resource on slot 3 shown in Fig. 4. As another example, as shown in Fig. 4, if the precision is "Sidelink SCS", slot 3 corresponds to "+3" (A is equal to 1) in Fig. 4, and if the precision is "UL SCS", slot 3 corresponds to "+6" (A is equal to 1) and "+7" (A is equal to 2) in 4. In this case, the PUCCH resource actually applied to feedback of sidelink HARQ-ACK information is any one of "+3", "+6", and "+7" in Fig. 4.

[0080] That is, if A is not equal to 1, TIFF0007617116000158.tif7161 or It is also called the second time-domain resource, the third time-domain resource, etc. in the time-domain range after TIFF0007617116000159.tif7161. Here, TIFF0007617116000160.tif7161 or The SCS corresponding to the time domain range of TIFF0007617116000161.tif7161 is different from the SCS corresponding to the "second time domain resource, third time domain resource".

[0081] In this example, Assume that TIFF0007617116000162.tif7161 is the beginning of the slot in which the PSFCH is located, and therefore TIFF0007617116000163.tif7161 corresponds to the UL SCS slot that corresponds to slot 1 in Figure 3. If TIFF0007617116000164.tif7161 is defined as the end of the slot in which the PSFCH is located, The slot corresponding to TIFF0007617116000165.tif7161 will be adjusted accordingly, e.g. moved backwards.

[0082] Example 4 Sidelink timing and Uu timing are aligned, i.e., the timing offset=0.

[0083] Assume that two sidelink transmissions are scheduled by DCI, K=N=2, UL SCS=30 kHz, and SL SCS=30 kHz. As shown in FIG. 5, TIFF0007617116000166.tif7161 slot, TIFF0007617116000167.tif7161 (30 kHz) slot, and at this time, the base station and the control node have the same understanding of the PUCCH resource, that is, the PUCCH resource is slot 1'.

[0084] Assume that two sidelink transmissions are scheduled by DCI, K=N=2, UL SCS=15kHz, and SL SCS=30kHz. As shown in FIG. TIFF0007617116000168.tif7161 slot, TIFF0007617116000169.tif7161 (15 kHz) slots, and in this case, the PUCCH resource is the nearest available Uu slot or UL slot after slot 1'.

[0085] Assume that two sidelink transmissions are scheduled by DCI, K=N=2, UL SCS=30 kHz, and SL SCS=15 kHz. As shown in FIG. TIFF0007617116000170.tif7161 slot, TIFF0007617116000171.tif7161 (30 kHz) slot, and in this case, the PUCCH resource is the nearest available Uu slot or UL slot after slot 1'.

[0086] Thus, in an embodiment of the present invention, the terminal and the control node and determining a time domain resource of a target uplink channel based on the first time domain position of the PSFCH and the time interval and determine a time domain resource of the target uplink channel based on TIFF0007617116000173.tif7161 and the second time domain position of the PSFCH, and determine a condition to be satisfied by the time domain resource of the target uplink channel, thereby achieving a consistent understanding between the terminal and the control node about the time domain resource of the target uplink channel, and further ensuring the validity of the resource allocation by the control node for the target uplink channel, and improving the accuracy of the terminal's determination of the resource of the target uplink channel.

[0100] It should be noted that the communication device provided in the embodiments of the present invention is a communication device capable of executing the above resource determination method, and all the embodiments of the above resource determination method are applicable to the communication device, and can achieve the same or similar beneficial effects.

[0101] Preferably, the embodiment of the present invention further provides a communication device, comprising a processor, a memory, and a computer program stored in the memory and executable by the processor. When the computer program is executed by the processor, each process of the resource determination method embodiment is realized, and the same technical effect can be achieved.

The computer-readable storage medium is, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disk.

[0103] As shown in FIG. 9, the embodiment of the present invention includes: Step 901 of obtaining at least one of a Sidelink timing, a Uu timing and a timing offset, where the timing offset is a time offset between a Sidelink timing and a Uu timing; and determining 902 a sidelink configured grant resource and / or a hybrid automatic repeat request (HARQ) process for the sidelink configured grant resource based on at least one of the sidelink timing, the Uu timing, and the timing offset.

[0104] The timing offset is an offset between Uu timing and Sidelink timing, and the accuracy of the offset may be at least one of microseconds (us), symbols, slots, subframes, milliseconds, frames, seconds, etc. In the formula, the timing offset may need to be converted to a corresponding unit. For example, it may be converted to at least one of us, symbols, slots, subframes, ms, seconds, and frames, but is not limited here.

[0105] The embodiments of the present invention provide at least three methods for determining a sidelink configured grant resource and / or a hybrid automatic repeat request (HARQ) process for the sidelink configured grant resource, which are as follows:

[0106] Method 1 Based on the sidelink timing (eg, direct frame number DFN), determine the sidelink configured grant resource and / or the hybrid automatic repeat request (HARQ) process of the sidelink configured grant resource.

[0107] Method 2 Determine a sidelink configured grant resource and / or a hybrid automatic repeat request (HARQ) process for the sidelink configured grant resource based on a Uu timing (eg, a system frame number SFN) and a timing offset.

[0108] Method 3 Determine a sidelink configured grant resource and / or a hybrid automatic repeat request (HARQ) process for the sidelink configured grant resource based on Uu timing (eg, system frame number SFN).

[0109] As an embodiment of method 3, The terminal assumes that TIFF0007617116000202.tif7161 is large enough to complete the steps related to the sidelink transmission / PSFCH transmission / reception / PUCCH / PUSCH process. In another embodiment, when transmitting a sidelink configuration grant resource, the terminal needs to transmit with TA / 2 or TA advance. In yet another embodiment, when transmitting a sidelink configuration grant resource, the terminal assumes or expects that the slot boundary where the sidelink configuration grant resource is located and the slot boundary, subframe boundary, or frame boundary derived after advancing the timing of the slot where the most recently received downlink control information or synchronization signal block SSB or channel state information reference signal CSI-RS or other downlink signal is located by TA / 2 or TA are aligned. It should be noted that the alignment of the boundaries does not mean that the boundaries overlap.

[0110] In one alternative embodiment, the method comprises: Interval between Downlink Control Information DCI and Sidelink Resource Indicated by DCI TIFF0007617116000203.tif7161 or Sidelink setting grant offset value TIFF0007617116000204.tif7161, Interval between the physical sidelink feedback channel PSFCH and the channel for transmitting sidelink HARQ-ACK information TIFF0007617116000205.tif7161, Time domain range occupied by data resources and / or control resources within Sidelink configuration grant resources TIFF0007617116000206.tif7161, further comprising determining a period of the sidelink configuration grant resource based on at least one of a period N of the PSFCH and an interval K between the PSFCH and a corresponding physical sidelink shared channel PSSCH. Optionally, K is a minimum interval between the PSFCH and the corresponding PSSCH.

[0111] For example, the period of the sidelink configuration grant resource is It will be larger than TIFF0007617116000207.tif7161, It is equal to TIFF0007617116000208.tif7161, It will be larger than TIFF0007617116000209.tif7161, is equal to TIFF0007617116000210.tif7161, It will be larger than TIFF0007617116000211.tif7161, It satisfies at least one of the following conditions: it is equal to TIFF0007617116000212.tif7161, TIFF0007617116000213.tif7161 is the interval between the downlink control information DCI and the sidelink resource indicated by the DCI or the offset value of the sidelink configuration grant (e.g., timeOffsetCGType1). Alternatively, the value may be 0, in which case, in the above formula, TIFF0007617116000214.tif7161 is missing. TIFF0007617116000215.tif7161 is the interval between the physical sidelink feedback channel PSFCH and the channel for transmitting Sidelink HARQ-ACK information. TIFF0007617116000216.tif7161 is the time domain range occupied by the data resources and / or control resources in the sidelink configuration grant resource. N is the period of the PSFCH. K is the minimum interval between the PSFCH and the corresponding physical sidelink shared channel PSSCH.

[0112] Selectively, TIFF0007617116000217.tif7161 may be indicated by DCI or may be set by a higher layer, and is not specifically limited here.

[0113] For example, in one period, if the data resource and the control resource in the sidelink configuration grant resource are located at sidelink slot 1, sidelink slot 9, and sidelink slot 10, respectively, then S1 corresponds to 10 sidelink slots, or S1 corresponds to the physical time length corresponding to sidelink slot 1 to sidelink slot 10.

[0114] Cycle By setting the period to TIFF0007617116000218.tif7161 or more, it is possible to ensure that the PSFCH corresponding to the last transmission in each period is within the corresponding period. TIFF0007617116000219.tif7161 or more, or the period By setting the resource size to TIFF0007617116000220.tif7161 or greater, it is possible to ensure that the PUCCH or PSUCH corresponding to the last transmission in each period is within the relevant resource.

[0115] Optionally, for Sidelink configuration grant resources, TIFF0007617116000221.tif7161 specifically means the interval between the last PSFCH associated with Sidelink transmission in each period and the corresponding PUCCH or PUSCH.

[0116] For example, the minimum periodicity is 3 sidelink slots, the timing offset is 0, the time domain range occupied by the time domain resource indicated by the sidelink control information is 1 slot, N=1, K=2, and y4=0.

[0117] What needs to be explained is the above TIFF0007617116000222.tif7161 or TIFF0007617116000223.tif7161 or The subcarrier spacing SCS of the parameter TIFF0007617116000224.tif7161 may be the same or different. Here, in one embodiment, K and N are logical slots (e.g., sidelink slots), TIFF0007617116000225.tif7161 and TIFF0007617116000226.tif7161 is a physical slot, and may also have different precision or SCS. Therefore, in the above formula, SCS conversion and / or joint conversion to logical time or physical time may be required, but is not specifically limited here.

[0118] When a period is defined according to physical time, if a sidelink setup grant resource collides with a non-sidelink resource, the sidelink setup grant resource in the colliding portion or the sidelink setup grant resource within the period is considered to be invalid.

[0119] Optionally, the step of determining a HARQ process of the sidelink configuration grant resource in step 902 includes: determining an HARQ process of the sidelink configuration grant resource based on a start value of the HARQ process and / or an offset value of the process; and / or determining, based on the identification information of a sidelink configuration grant resource, a HARQ process of the sidelink configuration grant resource corresponding to the identification information of the sidelink configuration grant resource.

[0120] In accordance with the above, in an embodiment of the present invention, the terminal and the control node determine a sidelink configuration grant resource and / or a hybrid automatic repeat request (HARQ) process for the sidelink configuration grant resource, based on at least one of the sidelink timing, the Uu timing, and the timing offset, thereby realizing that the terminal and the control node have the same understanding of the sidelink configuration grant resource, further ensuring the validity of the sidelink configuration grant resource allocation by the control node, and improving the accuracy of the sidelink configuration grant resource determination by the terminal.

[0121] In order to more clearly describe the resource determination method provided in the embodiment of the present invention, two embodiments are described in more detail below.

[0122] Example 5 Determine the sidelink configuration grant resource based on the DFN.

[0123] Assume that one Sidelink configuration grant resource is associated with nrofHARQ-Processes (number of HARQ processes), where S is the number in slots of the start symbols of one PSSCH transmission opportunity or PSCCH transmission opportunity in the Sidelink configuration grant resource (e.g., startSLsymbols).

[0124] Alternatively, "timeOffsetCGType1" may indicate the starting slot of the configured grant Type1 resource for DFN0#, or may be an offset, eg, a slot offset, of the configured grant Type1 resource for DFN0#.

[0125] For configured grant Type 1, the sidelink configuration grant resource is determined by the following formula, for example, the start symbol satisfies the following formula: [(DFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot) + (slot number in the frame × numberOfSymbolsPerSlot) + symbol number in the slot] = (timeDomainOffset × numberOfSymbolsPerSlot + S + N × periodicity) modulo (1024 × numberOfSlotsPerFrame × numberOfSymbolsPerSlot), for all N >= 0.
