Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to a Chinese patent application filed on September 23, 2021, bearing application number 202111117396.4 and entitled "Resource Determination Method, Apparatus, Terminal and Readable Storage Medium," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of communications technology, and specifically to a resource determination method, device, terminal, and readable storage medium. [Background technology]

[0003] The 5th Generation Mobile Communication (5G) system must adapt to diverse scenarios and business demands. The 5G system defines three major application scenarios: Enhanced Mobile Broadband (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC). These application scenarios require the system to have high reliability, low latency, wide bandwidth, and wide coverage. Some user equipment (UE) may support multiple different services. For example, a UE may support both the ultra-reliable and low-latency URLLC service and the high-capacity, high-rate eMBB service. In a 5G New Radio (NR) system, different channels can have different starting symbols and lengths, resulting in overlapping transmission resource time domains. However, when multiple overlapping physical uplink control channels (PUCCHs) are transmitted in one slot, the single-carrier characteristics of the UE are destroyed, and the difference in transmit power may cause degradation of channel estimation performance.

[0004] In the prior art, when uplink control information (UCI) is transmitted on a PUCCH, UCI transmitted on the same PUCCH has the same priority index and corresponds to one bit rate. However, in a scenario where UCIs with different priority indexes are multiplexed on the same PUCCH and UCIs with different priority indexes use different bit rates, how to determine the number of PRBs used when transmitting UCI is an issue that needs to be resolved quickly. Summary of the Invention [Problem to be solved by the invention]

[0019] The resource determination method according to the embodiments of the present application will be described in detail below through several embodiments and application scenarios thereof in conjunction with the drawings.

[0020] An embodiment of the present application provides a resource determination method, which considers that when a first UCI and a second UCI with priority indexes are multiplexed on the same PUCCH resource, the bit rates of the UCIs with different priority indexes are different, and determines the number of target physical resource blocks (PRBs) for transmitting the first UCI and the second UCI on the PUCCH resource based on the number of bits of the first UCI, the number of bits of the second UCI, the bit rate of the first UCI, and the bit rate of the second UCI, thereby ensuring the different reliability requirements of the UCIs with different priority indexes and improving the availability of the communication system.

[0021] FIG. 2 is a flowchart of a resource determination method according to an embodiment of the present application, which is used in a terminal. As shown in FIG. 2, the method includes the following steps:

[0022] In step 201, when a first UCI and a second UCI are multiplexed on the same PUCCH resource, a target number of PRBs for transmitting the first UCI and the second UCI on the PUCCH resource is determined based on the number of bits of the first UCI, the number of bits of the second UCI, the bit rate of the first UCI, and the bit rate of the second UCI, where a priority index of the first UCI is different from a priority index of the second UCI.

[0023] Optionally, the embodiments of the present application may be used in a 5G NR system, and when a first UCI and a second UCI with different priority indexes are multiplexed on the same PUCCH resource, one PUCCH format may be configured with two bit rates, i.e., the bit rate of the first UCI and the bit rate of the second UCI.

[0024] Optionally, the message types of the first UCI and the second UCI may include at least one of a Hybrid Automatic Repeat reQuest-ACK (HARQ-ACK), a Selective Repeat (SR), and Channel State Information (CSI).

[0025] Alternatively, the priority index of the first UCI is priority index 0 and the priority index of the second UCI is priority index 1, or the priority index of the first UCI is priority index 1 and the priority index of the second UCI is priority index 0.

[0026] It should be noted that different priority indexes in the present invention may be understood as different priorities, for example, the priority of the first UCI is low priority and the priority of the second UCI is high priority, or the priority of the first UCI is high priority and the priority of the second UCI is low priority.

[0027] The resource determination method according to an embodiment of the present application takes into account that when UCIs with different priority indexes are multiplexed on the same PUCCH resource, the bit rates of the UCIs with different priority indexes are different, and determines the number of PRBs used for PUCCH transmission based on the bit numbers and bit rates of the UCIs with different priority indexes, thereby ensuring the different reliability requirements of the UCIs with different priority indexes and improving the availability of the communication system.

[0028] Optionally, when the first UCI and the second UCI are multiplexed on the same PUCCH resource in step 201, an implementation manner for determining the target number of PRBs for transmitting the first UCI and the second UCI on the PUCCH resource based on the number of bits of the first UCI, the number of bits of the second UCI, the bit rate of the first UCI, and the bit rate of the second UCI includes at least one of the following:

[0029] Method 1: When the first UCI and the second UCI are multiplexed on the same PUCCH resource and transmitted using a target PUCCH format, a first number of PRBs is determined based on the number of bits of the first UCI and the bit rate of the first UCI, and a second number of PRBs is determined based on the number of bits of the second UCI and the bit rate of the second UCI, and the target number of PRBs for transmitting the first UCI and the second UCI on the PUCCH resource is the sum of the first number of PRBs and the second number of PRBs.

[0030] Alternatively, the target PUCCH format may include PUCCH format 2 or PUCCH format 3.

[0032] TIFF0007763332000002.tif45170TIFF0007763332000003.tif45170TIFF0007763332000004.tif154170

[0033] Alternatively, when the target PUCCH format is PUCCH format 3, the first PRB number is an integer multiple of 2, 3, or 5, and the second PRB number is an integer multiple of 2, 3, or 5, and see equations (7) and (8): TIFF0007763332000005.tif25170

[0034] Alternatively, if the target PUCCH format is PUCCH format 3, the target PRB number for transmitting the first UCI and the second UCI on the PUCCH resource is an integer multiple of 2, 3, or 5, and is expressed as: TIFF0007763332000006.tif15170

[0035] Optionally, after determining the first number of PRBs and the second number of PRBs according to Scheme 1, the implementation manner in which the terminal performs rate matching and resource mapping on the PUCCH resources may include performing rate matching and resource mapping within the PRBs of the first number of PRBs for a first UCI, and performing rate matching and resource mapping within the PRBs of the second number of PRBs for a second UCI.

[0036] TIFF0007763332000007.tif44170TIFF0007763332000008.tif30170TIFF0007763332000009.tif138170

[0037] Alternatively, if the target PUCCH format is PUCCH format 3, the target PRB number for transmitting the at least two UCIs on the PUCCH resource in mode 2 is an integer multiple of 2, 3, or 5, and can refer to equation (9).

[0038] Alternatively, if the first interlace is configured on the PUCCH resource, the terminal may determine the interlace used for PUCCH transmission according to at least one of the following methods.

[0039] Manner a: When a first interlace and a second interlace are configured on a PUCCH resource, the first UCI and the second UCI are transmitted on the first interlace and the second interlace.

[0040] Manner b: When a first interlace is configured on a PUCCH resource, the first UCI and the second UCI are transmitted on the first interlace.

[0041] Scheme c: When a first interlace is configured on a PUCCH resource and the number of PRBs included in the first interlace meets a target condition, the first UCI and the second UCI are transmitted on the first interlace.

[0042] TIFF0007763332000010.tif94170

[0043] Method d: When a first interlace and a second interlace are configured on a PUCCH resource and the number of PRBs included in the first interlace does not satisfy a target condition, the first UCI and the second UCI are transmitted on the first interlace and the second interlace.

[0044] Alternatively, after determining the target number of PRBs for transmitting the first UCI and the second UCI on the PUCCH resource according to Scheme 2, the implementation manner in which the terminal performs rate matching and resource mapping on the PUCCH resource may include performing rate matching and resource mapping for both the first UCI and the second UCI within the PRBs of the target number of PRBs.

[0045] Specifically, the terminal first determines the number of first resource elements (REs) in a PRB of the target PRB number that satisfies the bit rate of the first UCI based on the number of bits of the first UCI and the bit rate of the first UCI, then performs rate matching and resource mapping for the first UCI on the first RE, and performs rate matching and resource mapping for the second UCI on the first RE and REs other than REs used by a demodulation reference signal (DMRS) in the PRB of the target PRB number; Alternatively, the terminal first determines the number of second resource elements (RE) within a PRB of the target PRB number that satisfies the bit rate of the second UCI based on the number of bits of the second UCI and the bit rate of the second UCI, and then performs rate matching and resource mapping for the second UCI on the second RE, and performs rate matching and resource mapping for the first UCI on REs within a PRB of the target PRB number other than the second RE and REs used by DMRS.

[0046] In the following, a resource determination method according to an embodiment of the present application will be described by taking as an example that the first UCI is a low priority index (LP) HARQ-ACK and the second UCI is a high priority index (HP) HARQ-ACK.

[0053] Alternatively, if the first interlace is configured for the PUCCH on which the terminal transmits the LP HARQ-ACK and the HP HARQ-ACK, the terminal may determine the interlace to be used for PUCCH transmission according to at least one of the following methods:

[0054] Method a): When the first interlace and the second interlace are configured on the PUCCH resource, the LP HARQ-ACK and the HP HARQ-ACK are transmitted on the first interlace and the second interlace.

[0055] Method b): If the first interlace is configured on the PUCCH resource, the LP HARQ-ACK and the HP HARQ-ACK are transmitted on the first interlace.

[0056] Method c): If the first interlace is configured on the PUCCH resource and the number of PRBs included in the first interlace meets the target condition, the LP HARQ-ACK and the HP HARQ-ACK are transmitted on the first interlace.

[0057] TIFF0007763332000019.tif31170TIFF0007763332000020.tif159170

[0058] Method d): When the first interlace and the second interlace are configured on the PUCCH resource and the number of PRBs included in the first interlace does not satisfy the target condition, the LP HARQ-ACK and the HP HARQ-ACK are transmitted on the first interlace and the second interlace.

[0059] In the prior art, when UCI is transmitted on the PUCCH, a frequency-domain-first resource mapping scheme is used. Figure 3 is a schematic diagram of the resource mapping scheme used when UCI is transmitted on the PUCCH in the prior art. As shown in Figure 3, after the UE performs rate matching and coding modulation within the determined PRB on the entire PUCCH resource, the UE performs resource mapping according to a frequency-domain-first scheme. That is, the UE first maps the first RE of the first OFDM symbol (corresponding to the first symbol in the figure), then maps the second RE, third RE, ... of the first OFDM symbol in a frequency-incremental manner, up to the last RE of the first OFDM symbol, and then maps in the same manner from the first RE of the second OFDM symbol to the last RE of the last symbol of the PUCCH resource. It should be noted that UCI cannot be mapped onto the RE of a DMRS. For example, the third symbol shown in the vertical grid in Figure 3 is used by a DMRS, and UCI is not mapped onto the third symbol.
