Description

Communication method and device, and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 28, 2023, with application number 202311606809.4 and invention name “Communication method and device, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0003] The rapid growth in uplink service demand has led to higher requirements for uplink coverage, speed, and latency. Due to the limitations of the uplink and downlink time slot ratios in time division duplexing (TDD) systems, TDD systems experience significant transmission latency. To reduce base station implementation complexity, all frequency resources on a TDD carrier must transmit in the same direction at any given moment—either uplink or downlink. This means that the uplink and downlink time slot ratios for different frequency resources on a TDD carrier cannot be flexibly configured. With the diversification of services, especially those in vertical industries, different services have varying uplink and downlink transmission requirements. A single uplink and downlink time slot ratio cannot meet these diverse needs. Based on these two considerations and considering base station implementation complexity, the proposed subband full duplex (SBFD) solution utilizes different uplink and downlink time slot ratios for different subbands on the same carrier. As shown in Figure 1 below, on the base station side, subbands are leveraged to divide uplink and downlink transmission in the frequency domain, where D represents a downlink subband and U represents an uplink subband. While simultaneously transmitting uplink and downlink signals on different subbands, frequency division is also used to reduce interference, lowering base station complexity and making implementation easier. For terminal devices, half-duplex is still supported, meaning that at any given time, only downlink reception can be performed on the downlink subband or uplink transmission can be performed on the uplink subband.

[0004] In existing technology, SBFD is being considered for initial access, which can increase initial access coverage. This allows users to transmit the Physical Random Access Channel (PRACH) and Message 3 (Msg3) in the SBFD uplink subband, increasing uplink transmission resources, helping to reduce initial access latency and increase PRACH and Msg3 coverage. The Physical Uplink Control Channel (PUCCH) resources used for the Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) feedback for Message 2 (Msg2) reception are located at both ends of the initial uplink bandwidth part (initial UL BWP).

[0005] However, to accommodate both SBFD and non-SBFD time units, the initial uplink bandwidth needs to cover all non-SBFD uplink resources. However, an SBFD time unit typically has only one uplink subband, which cannot cover both ends of the initial uplink bandwidth. Consequently, all or part of the PUCCH resources used to feedback the HARQ-ACK received for Msg2 are not in the uplink subband, resulting in no or very few frequency domain resources for HARQ-ACK feedback in the SBFD time unit, increasing access latency. Summary of the Invention

[0043] This application mainly relates to the communication between terminal devices and network devices. Among them:

The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0046] As described in the background technology, there is usually only one uplink subband corresponding to the SBFD time unit, which cannot cover both ends of the initial uplink bandwidth at the same time. Therefore, all or part of the PUCCH resources used to feedback the HARQ-ACK received by Msg2 are not in the uplink subband, resulting in no or very few frequency domain resources for HARQ-ACK feedback in the SBFD time unit, resulting in increased latency.

[0047] Specifically, the method for determining PUCCH frequency domain resources in the prior art is as follows: a PUCCH resource set (PUCCH set) is determined in a common resource set (PUCCH-Resource Common) by selecting a row in Table 1. Each row represents a PUCCH resource set, and a PUCCH resource set includes 16 PUCCH resources. These 16 PUCCH resources are determined by an index, and this index is determined by the first control channel element (Control Channel Element, CCE) index (n CCE，0 ), the number of CCEs in the control resource set (ControlResourceSet, CORESET) of the physical downlink control channel (Physical Downlink Control Channel, PDCCH) (N CCE) and the PUCCH resource indicator in the downlink control information (DCI).

[0048] When the PUCCH resource index r PUCCH When it is less than 8, the terminal device determines the physical resource block (PRB) index of the frequency domain position of the first hop of the PUCCH resource as shown in formula (1):

[0049] The PRB index of the frequency domain position of the second hop is shown in formula (2):

[0050] in, Indicates the size of the initial uplink BWP, Indicates the PRB offset between the frequency domain position of the first hop of the PUCCH resource and the frequency domain position of the initial uplink BWP start. Indicates rounding down, r PUCCH Indicates the index of PUCCH, N CS Indicates the number of cyclic shifts (CS), which can be specifically determined by the set of initial CS indexes in Table 1.

[0051] When the PUCCH resource index is greater than or equal to 8, the terminal device determines the PRB index of the frequency domain position of the first hop of the PUCCH resource as shown in formula (3):

[0052] The PRB index of the frequency domain position of the second hop is shown in formula (4):

[0053] Table 1

[0054] However, since the frequency domain position of the PUCCH resource is based on the PRB index, it is also based on the initial uplink BWP position, and the PRB offset in Table 1 is are very small, so these PUCCH resources are located at both ends of the initial uplink BWP.

[0055] The technical solution of the present application controls the frequency domain resources of PUCCH to be located within the above-mentioned overlapping frequency domain resources, so that the frequency domain resources of PUCCH are located within the uplink subband corresponding to the SBFD time unit, thereby ensuring the successful transmission of the information carried on PUCCH, such as the HARQ-ACK for feedback of Msg2 reception, thereby improving the access success rate.

[0056] The SBFD time unit in this embodiment refers to a time unit for configuring SBFD in a corresponding frequency domain. The unit of the time unit may be a time slot, a symbol, a subframe, or the like.

[0057] Accordingly, the non-SBFD time unit in this embodiment refers to a time unit in which SBFD is not configured in the corresponding frequency domain.

[0058] The uplink subband referred to in this embodiment refers to continuous frequency domain resources used for uplink transmission, and may specifically include one or more resource blocks (RBs).

[0059] Accordingly, the downlink subband referred to in this embodiment refers to continuous frequency domain resources used for downlink transmission, and may specifically include one or more resource blocks.

[0060] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0061] Referring to FIG2 , the method provided in this application specifically includes the following steps:

[0062] Step 201: The terminal device sends a PUCCH to the network device. The frequency domain resources of the PUCCH are located in the overlapping frequency domain resources of the uplink subband corresponding to the initial uplink BWP and the SBFD time unit.

[0063] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0064] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0065] The PUCCH resource referred to in this embodiment can be a PUCCH resource used to feedback the HARQ-ACK received by Msg2, or it can be a PUCCH resource that carries other appropriate information. This application does not impose any restrictions on this.

[0066] In this embodiment, the overlapping frequency domain resources refer to the resources where the initial uplink BWP and the uplink subband corresponding to the SBFD time unit overlap in the frequency domain. The overlapping frequency domain resources vary with the carrier subband frequency domain pattern and / or the position of the initial uplink BWP.

[0067] For details, please refer to Figure 3. The corresponding subband frequency domain pattern a on the SBFD time unit carrier is DUD. The overlapping frequency domain resources under different initial uplink BWPs are shown in the shaded area in Figure 3. When the initial uplink BWP is located as shown in b1 in Figure 3, the overlapping frequency domain resources are located in the middle of the initial uplink BWP. When the initial uplink BWP is located as shown in b2 or b3 in Figure 3, the overlapping frequency domain resources are located at both ends of the initial uplink BWP.

[0068] It should be noted that the above embodiment is described using the carrier subband frequency domain pattern as DUD as an example. In actual application scenarios, the carrier subband frequency domain pattern can also be in the form of DU or UD, and this application does not impose any restrictions on this.

[0069] Regardless of how the carrier subband frequency domain pattern and / or the position of the initial uplink BWP are configured, in this embodiment, the frequency domain resources of the PUCCH can be located in the above-mentioned overlapping frequency domain resources, which means that the frequency domain resources of the PUCCH are located both in the initial uplink BWP and in the uplink subband corresponding to the SBFD time unit, thereby ensuring the smooth transmission of the PUCCH.

[0070] The following describes in detail how a terminal device makes the frequency domain resources of the PUCCH located in the overlapping frequency domain resources in combination with different embodiments.

[0071] In embodiment 1, the frequency domain resources of the PUCCH are determined based on the starting frequency domain position and the ending frequency domain position of the overlapping frequency domain resources, where the starting frequency domain position and the ending frequency domain position of the overlapping frequency domain resources are their PRB indexes.

[0072] Specifically, referring to FIG4 , when the resource index of the PUCCH is less than the first threshold, the position of the first frequency hopping domain resource P1 is the sum of the starting frequency domain position F1 of the overlapping frequency domain resource, the first offset, and the second offset. The first offset is the frequency domain offset between the position of the first frequency hopping domain resource obtained by looking up the table and the starting frequency domain position F1 of the initial uplink BWP, and the second offset represents the frequency domain offset between the frequency hopping domain resources. The second offset can be determined based on the resource index of the PUCCH and the number of CSs, and the number of CSs can be determined based on Table 1. For example, the second offset is The position of the second frequency-hopping domain resource P1 is the difference between the ending frequency-domain position F2 of the overlapping frequency-domain resource and the first offset and the second offset.

[0073] When the resource index of PUCCH is not less than the first threshold, the position of the first frequency hopping domain resource is the difference between the ending frequency domain position F2 of the overlapping frequency domain resource and the first offset and the second offset, and the position of the second frequency hopping domain resource is the sum of the starting frequency domain position F1 of the overlapping frequency domain resource and the first offset and the second offset.

[0074] Taking the first threshold of 8 as an example, when the PUCCH resource index is less than 8, the PRB index of the frequency domain position of the first hop of the PUCCH resource is as shown in formula (5):

[0075] The PRB index of the frequency domain position of the second hop of the PUCCH resource is shown in formula (6):

[0076] Among them, F1 represents the starting PRB index of the overlapping frequency domain resources, and F2 represents the ending PRB index of the overlapping frequency domain resources.

[0077] When the PUCCH resource index B is not less than 8, the PRB index of the frequency domain position of the first hop of the PUCCH resource is as shown in formula (7):

[0078] The PRB index of the frequency domain position of the second hop of the PUCCH resource is shown in formula (8):

[0079] In an optional embodiment, for a non-SBFD time unit, the starting PRB index F1 of the overlapping frequency domain resources in the above formula is 0, and the ending PRB index F2 of the overlapping frequency domain resources is

[0080] In embodiment 2, the frequency domain resources of PUCCH are determined based on the starting frequency domain position of the overlapping frequency domain resources and the ending frequency domain position of the overlapping frequency domain resources, and the starting frequency domain position and the ending frequency domain position of the overlapping frequency domain resources are their common resource block (CRB) indexes.

[0081] Different from the above-mentioned embodiment in which the PRB index is used to represent the resource, this embodiment uses the CRB index to represent the frequency domain resource position.

[0082] Specifically, the position of the frequency domain resource of the PUCCH is calculated according to the CRB index corresponding to the start PRB index of the overlapping frequency domain resource and the CRB index corresponding to the end PRB index of the overlapping frequency domain resource.

[0083] Taking the first threshold of 8 as an example, when the PUCCH resource index is less than 8, the CRB index of the frequency domain position of the first hop of the PUCCH resource is as shown in formula (9):

[0084] The CRB index of the frequency domain position of the second hop of the PUCCH resource is shown in formula (10):

[0085] When the PUCCH resource index B is not less than 8, the CRB index of the frequency domain position of the first hop of the PUCCH resource is as shown in formula (11):

[0086] The CRB index of the frequency domain position of the second hop of the PUCCH resource is shown in formula (12):

[0087] Among them, F1 represents the starting CRB index of the overlapping frequency domain resources, and F2 represents the ending CRB index of the overlapping frequency domain resources.

[0088] In an optional embodiment, for a non-SBFD time unit, the starting CRB index F1 of the overlapping frequency domain resource in the above formula is the CRB index N corresponding to the starting PRB index of the initial uplink BWP. BWP start , the ending PRB index F2 of the overlapping frequency domain resources is the CRB index corresponding to the ending PRB index of the initial uplink BWP.

[0089] In the above-mentioned embodiments 1 and 2, when the initial uplink BWP covers the uplink subband corresponding to the entire SBFD time unit, the starting PRB index of the overlapping frequency domain resources is the starting PRB index of the uplink subband, and the ending PRB index of the overlapping frequency domain resources is the ending PRB index of the uplink subband.

[0090] Example 3: The frequency domain resources of PUCCH are determined by searching in a table of PUCCH resource sets based on the carrier subband frequency domain pattern and / or the position of the initial uplink BWP corresponding to the SBFD time unit. The table of PUCCH resource sets includes the position of the first frequency hopping domain resources and the position of the second frequency hopping domain resources in the frequency domain resources of PUCCH.

[0091] In this embodiment, when each carrier subband frequency domain pattern and / or the position of the initial uplink BWP is configured in the PUCCH resource set table, the position of the first frequency hopping domain resource and the position of the second frequency hopping domain resource can be determined. Specifically, the position of the first frequency hopping domain resource and the position of the second frequency hopping domain resource can use a PRB index or a CRB index.

[0092] 5 , the subband frequency domain pattern a on the carrier is DUD. When the position of the initial uplink BWP is as shown in FIG. 5 b1 , FIG. 2 and FIG. 3 , the position P1 of the first frequency hopping domain resource and the position P2 of the second frequency hopping domain resource are different.

[0093] Specifically, multiple new rows may be added to the table of the PUCCH resource set, where the new rows include the position P1 of the first frequency hopping domain resource and the position P2 of the second frequency hopping domain resource in the frequency domain resources of the PUCCH.

[0094] In a specific implementation, the network device sends an indication to the terminal device, and the terminal device selects a corresponding newly added row in the table of the PUCCH resource set according to the indication. The terminal device selects the position of the first frequency hopping domain resource and the position of the second frequency hopping domain resource in the newly added row as the PUCCH frequency domain resource corresponding to the current SBFD time unit.

[0095] Example 4: The position of one of the first frequency hopping domain resources and the second frequency hopping domain resources in the frequency domain resources of PUCCH is determined by searching in the table of the PUCCH resource set based on the carrier subband frequency domain pattern and / or the position of the initial uplink BWP corresponding to the SBFD time unit, and the position of another frequency hopping domain resource in the frequency domain resources of PUCCH is determined based on the position of the aforementioned determined frequency hopping domain resources and the third offset. The table of the PUCCH resource set includes the position of one of the first frequency hopping domain resources and the second frequency hopping domain resources and the third offset.

[0096] Unlike the previous embodiment in which the position of the first frequency hopping domain resource and the position of the second frequency hopping domain resource are directly configured in the PUCCH resource set table, this embodiment configures the position of the first frequency hopping domain resource and the third offset between the position of the first frequency hopping domain resource and the position of the second frequency hopping domain resource in the PUCCH resource set table, or configures the position of the second frequency hopping domain resource and the third offset between the position of the first frequency hopping domain resource and the position of the second frequency hopping domain resource in the PUCCH resource set table.

[0097] For example, referring to Figure 5 , if carrier subband frequency domain pattern a is DUD and the position of the initial uplink BWP is as shown in Figure b1 in Figure 5 , the position P1 of the first frequency hopping domain resource and the corresponding third offset are configured in the PUCCH resource set table. Accordingly, if the position of the initial uplink BWP is as shown in Figures b2 and b3 in Figure 5 , the corresponding position P1 of the first frequency hopping domain resource and the corresponding third offset are configured, respectively.

[0098] In one embodiment, different PRB offsets can be configured in the PUCCH resource set table for different carrier subband frequency domain patterns and / or initial uplink BWP positions. And calculate the PUCCH resource index r by the above formula (1) PUCCHWhen it is less than 8, the position of the first frequency hopping domain resource P1 is calculated, and the position of the second frequency hopping domain resource P2 is calculated by the third offset.
