Abstract
Description
[Technical field]
[0001] The present disclosure relates to the field of communications technology, and in particular to a frequency domain resource determination method, device, and storage medium. [Background technology]
[0002] In New Radio (NR), for example, when the communication bandwidth is in frequency range 2 (FR2), the high frequency channel attenuates rapidly, so beam-based transmission and reception is necessary to ensure coverage. When a network device (such as a base station) has multiple Transmission Reception Points (TRPs), multiple TRPs can be used to serve terminals, including transmitting physical downlink control channels (PDCCHs) to terminals using multiple TRPs.
[0003] In the related art, when PDCCH transmission is performed using multiple TRPs, two control resource sets (CORESET) can be configured, and a TCI state corresponding to the CORESET can be configured. One TCI state is configured corresponding to each CORESET, and search space sets (SS sets) associated with the two CORESETs are configured. That is, two SS sets having a link relationship associated with different CORESETs and corresponding to different TCI states are configured. The two SS sets having a link relationship may be understood as two PDCCH candidates having the same PDCCH candidate resource index in the two SS sets being used to transmit one downlink control information (DCI).

[0041] Exemplary embodiments are described in detail herein, examples of which are shown in the drawings. When the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.
[0042] The frequency domain resource determination method provided by the embodiment of the present disclosure is applicable to the wireless communication system shown in Fig. 1. As shown in Fig. 1, the wireless communication system includes a terminal and a network device. The terminal is connected to the network device through a wireless resource and transmits and receives data.
[0043] It should be understood that the wireless communication system illustrated in Fig. 1 is merely a schematic illustration, and the wireless communication system may include other network devices, such as core network devices, wireless relay devices, wireless backhaul devices, etc., which are not illustrated in Fig. 1. In the embodiment of the present disclosure, the number of network devices and terminals included in the wireless communication system is not limited.
[0044] Furthermore, the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system may adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance, etc. Depending on factors such as capacity, speed, and delay of different networks, the network may be classified into 2G (English: generation) network, 3G network, 4G network, or future evolution network such as 5G network, also called New Radio (NR) network. For convenience of explanation, the wireless communication network may be simply referred to as a network in this disclosure.
[0045] Further, the network device according to the present disclosure may be referred to as a radio access network device. The radio access network device may be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a radio relay node, a radio backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., or may be a gNB in an NR system, or may be a component or part of a device constituting a base station, etc. In the case of a vehicle Internet (V2X) communication system, the network device may be an in-vehicle device. It should be understood that the embodiments of the present disclosure are not limited to a specific technology used by the network device and a specific device form.
[0046] Furthermore, the terminal according to the present disclosure may be called a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides a voice and / or data connection to a user. For example, the terminal may be a handheld device with a wireless connection function, an in-vehicle device, etc. Currently, some terminals may be a smartphone (Mobile Phone), a pocket personal computer (PPC), a portable computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or an in-vehicle device, etc. In the case of a vehicle-to-everything (V2X) communication system, the terminal device may be an in-vehicle device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and the specific device form used by the terminal.
[0047] In the present disclosure, data transmission is performed between a network device and a terminal based on a beam. In the process of performing data transmission based on a beam, a network device (such as a base station) transmits a PDCCH to a terminal using multiple TRPs (multiple TRPs are also called Multi-TRPs). In the related technology, when a network device (such as a base station) transmits a PDCCH to a terminal using one TRP, the network device sets a TCI state for receiving the PDCCH to the terminal. For example, in a setting method, one CORESET, for example, CORESET#1, is set to the terminal, and a TCI state used when the terminal receives a PDCCH in the CORESET#1 resource is set as TCI#1. Furthermore, one search space set (SS set) associated with CORESET#1 is set to the terminal. When the terminal receives a PDCCH on a resource in the SS set, reception is performed using a beam corresponding to TCI#1. Currently, each SS set can be associated with only one CORESET, and only one TCI state (TCI state is also called TCI state) is set to each CORESET.
[0048] In the present disclosure, data transmission is performed between a network device and a terminal based on a beam. In the process of data transmission based on a beam, when a network device (such as a base station) uses multiple TRPs (multiple TRPs are also called Multi-TRPs) to transmit a PDCCH to a terminal, different TRPs transmit using different beams. Multiple TRPs can transmit the same PDCCH.
[0049] In order to realize that multiple TRPs transmit the same PDCCH, there is currently a method of configuring two CORESETs, configuring one TCI state for each CORESET, and configuring SS sets associated with the two CORESETs, respectively. That is, two SS sets associated with different CORESETs and corresponding to different TCI states are configured. The PDCCH candidates of the two SS sets having an association relationship also have an association relationship. For example, when SS set#1 is associated with SS set#2, PDCCH candidate#i in SS set#1 is associated with PDCCH candidate#i of SS set#2, that is, two PDCCH candidates with the same index are used to transmit the same DCI, that is, the DCI information transmitted by the two PDCCH candidates is the same.
[0050] One application scenario in which multiple TRPs transmit the same PDCCH is Multi-TRP PDCCH repetition. In Multi-TRP PDCCH repetition, two CORESETs are configured, and a TCI state corresponding to the CORESETs is configured. One TCI state is configured corresponding to each CORESET, and two SS sets having a link relationship are configured, which are associated with different CORESETs and correspond to different TCI states. The two SS sets having a link relationship may be understood as two PDCCH candidates having the same PDCCH candidate index in the two SS sets being used to transmit the same DCI, that is, the information of DCI transmitted by the two PDCCH candidates is the same.

[0054] 2 is a flowchart of a frequency domain resource determination method according to an exemplary embodiment. As shown in FIG. 2, the frequency domain resource determination method is applied to a terminal and includes the following steps S11 and S12.
[0055] In step S11, at least two PDCCH candidates are monitored, and the at least two PDCCH candidates are associated with at least two SS sets having a link relationship. vs. and at least two PDCCH candidates carry DCI. Beauty The DCI includes frequency domain resource allocation information, which indicates the location of frequency domain resources in a specified bandwidth. death ,The ,specified ,bandwidth ,includes ,RBs ,occupied ,by ,at ,least ,one ,CORESET.
[0056] In step S12, a frequency domain resource for transmitting the PDSCH is determined based on the frequency domain resource allocation information.
[0057] In the present disclosure, at least two PDCCH candidates are used to carry DCI, which may be understood as transmitting DCI based on at least two PDCCH candidates, where the information included in the DCI transmitted by the at least two PDCCH candidates is the same, and the DCI transmitted by the at least two PDCCH candidates may be understood as one and the same DCI.
[0058] In the present disclosure, the format of the DCI transmitted by the at least two PDCCH candidates may be DCI format 1_0.
[0059] In the present disclosure, the indexes of at least two PDCCH candidates monitored by a terminal are the same.
[0060] In the present disclosure, the at least two monitored PDCCH candidates may be understood as corresponding PDCCH candidates in a Multi-TRP PDCCH repetition scenario.
[0061] In this disclosure, a typical value of the number of PDCCH candidates in the at least two PDCCH candidates monitored by the terminal is two.
[0062] In one example, in the multi-TRP PDCCH repetition, the terminal monitors two PDCCH candidates, and these two PDCCH candidates are two SS sets having a link relationship. vs. In response, the indexes of the two PDCCH candidates are the same and are used to transmit one and the same DCI. The DCI includes frequency domain resource allocation information, which indicates the location of a frequency domain resource in a specified bandwidth. death ,The ,specified ,bandwidth ,includes ,RBs ,occupied ,by ,at ,least ,one ,CORESET.
[0063] Two SS sets having a link relationship may be understood as two PDCCH candidates having the same PDCCH candidate index in the two SS sets being used to transmit the same DCI.
[0064] In the present disclosure, when a terminal determines a frequency domain resource for transmitting a PDSCH based on frequency domain resource allocation information, the terminal may map the frequency domain resource indicated by the frequency domain resource allocation information to a designated RB included in a designated bandwidth, and determine the designated RB as the frequency domain resource for transmitting a PDSCH. The designated bandwidth includes RBs occupied by at least one CORESET.
[0065] In the present disclosure, frequency domain resource allocation information is included in the DCI carried in at least two PDCCH candidates monitored by the terminal, and the frequency domain resource indication information is used to indicate the location of a frequency domain resource in a specified bandwidth, and the specified bandwidth includes RBs occupied by at least one CORESET. Thus, the terminal determines the frequency domain resource for transmitting the PDSCH based on the frequency domain resource indication information terminal. Therefore, according to the present disclosure, the determination of the frequency domain resource of the PDSCH becomes more versatile, and even when the frequency domain resources of the CORESET corresponding to the two PDCCH candidates used for the PDCCH repetition are different, the frequency domain resource for transmitting the PDSCH can be clarified, and the transmission performance is improved.
[0066] In an embodiment of the present disclosure, a scheme for determining at least one CORESET included in a specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is described below.
[0067] In one embodiment of the present disclosure, at least one CORESET included in a specified bandwidth corresponding to a frequency domain resource indicated by the frequency domain resource allocation information is determined based on at least two CORESETs associated with at least two SS sets, respectively. The at least two SS sets have a link relationship. The at least two SS sets having a link relationship are determined based on at least two PDCCH candidates monitored by the terminal. vs. There is a correspondence relationship.
[0068] At least one CORESET included in the specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is a specified CORESET among at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0069] In an embodiment of the present disclosure, the specified CORESET is one of A to D below. A: A CORESET with the smallest CORESET identifier among at least two CORESETs respectively associated with at least two SS sets having a link relationship. B: CORESET corresponding to a specified SS set. The specified SS set is an SS set with the smallest SS set identifier among at least two SS sets having a link relationship. C: A CORESET corresponding to a PRB that occupies the lowest frequency domain position among the designated physical resource blocks (PRBs). The designated PRB is the PRB with the lowest PRB number. The PRB with the lowest PRB number is the PRB with the lowest number among the PRBs included in each CORESET of at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0070] In the present disclosure, the at least two CORESETs may be CORESET#0 and CORESET#1. Here, the PRB with the lowest frequency domain position among the PRBs occupied by CORESET#0 is PRB#i, and the PRB with the lowest frequency domain position among the PRBs occupied by CORESET#1 is PRB#j. If the frequency domain of PRB#i is lower than that of PRB#j, the designated CORESET is CORESET#0; otherwise, the designated CORESET is CORESET#1.
[0071] D: At least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0072] In the present disclosure, in response to the designated CORESET being at least two CORESETs respectively associated with at least two SS sets having a link relationship, the designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information includes all PRBs occupied by the at least two CORESETs respectively associated with the at least two SS sets having a link relationship. The designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information may be understood as including consecutive PRBs from a first PRB to a second PRB. The first PRB is a PRB that occupies the lowest frequency domain position among the PRBs included in the at least two CORESETs, and the second PRB is a PRB that occupies the highest frequency domain position among the PRBs included in the at least two CORESETs.
[0073] In the present disclosure, in one aspect, in response to the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship being consecutive or overlapping, the consecutive PRBs from the first PRB to the second PRB are PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship. Figure 3 shows a schematic diagram of PRBs occupied by frequency domain resources according to an exemplary embodiment of the present disclosure. Referring to Figure 3, the consecutive PRBs from the first PRB to the second PRB are a bandwidth occupied by frequency domain resources for transmitting a PDSCH.
[0074] In the present disclosure, in another aspect, in response to the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship not being consecutive, the consecutive PRBs from the first PRB to the second PRB are the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship, and the interval PRB between the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship. Figure 4 shows a schematic diagram of the PRBs occupied by frequency domain resources according to an exemplary embodiment of the present disclosure. Referring to Figure 4, the consecutive PRBs including the interval PRB from the first PRB to the second PRB are the bandwidth occupied by the frequency domain resources for transmitting the PDSCH.
[0075] In another embodiment of the present disclosure, at least one CORESET included in the designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is CORESET 0. In other words, the CORESET included in the designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is unrelated to at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0076] Furthermore, the above frequency domain resource determination method provided by the present disclosure is suitable for non-interleaved virtual resource block-to-physical resource block (VRB-to-PRB) mapping.
[0077] According to the above frequency domain resource determination method provided by the present disclosure, when a terminal performs PDCCH repetition, DCI format 1_0 is carried on the PDCCH, and the frequency domain bandwidth for transmitting the PDSCH may be a frequency domain bandwidth corresponding to CORESET#0, or may be a specified bandwidth determined based on at least two CORESETs associated with at least two SS sets, respectively. The frequency domain resources of the CORESETs corresponding to the two PDCCH candidates used for PDCCH repetition may be the same or different.
[0078] In the frequency domain resource determination method provided by the present disclosure, when a terminal performs PDCCH repetition, a bandwidth corresponding to a frequency domain resource indicated by frequency domain resource indication information included in DCI is clarified, and a frequency domain resource for transmitting a PDSCH is determined. Therefore, according to the present disclosure, the determination of the frequency domain resource of the PDSCH becomes more versatile, and even when the frequency domain resources of the CORESET corresponding to two PDCCH candidates used for PDCCH repetition are different, the frequency domain resource for transmitting a PDSCH can be clarified, thereby improving transmission performance.
[0079] Based on the same idea, the embodiment of the present disclosure further provides a frequency domain resource determination method applied to a network device.
[0080] 5 is a flowchart of a frequency domain resource determination method according to an exemplary embodiment. The frequency domain resource determination method may be implemented alone or in combination with other embodiments of the present disclosure. As shown in FIG. 5, the frequency domain resource determination method is used in a network device and includes the following step S21.
[0081] In step S21, at least two PDCCH candidates are configured, and the at least two PDCCH candidates are associated with at least two SS sets having a link relationship. vs. Corresponding relationship, and at least two PDCCH candidates carry DCI. Beauty The DCI includes frequency domain resource allocation information, which indicates the location of frequency domain resources in a specified bandwidth. death ,The ,specified ,bandwidth ,includes ,RBs ,occupied ,by ,at ,least ,one ,CORESET.
[0082] In the present disclosure, the use of at least two PDCCH candidates to carry DCI may be understood as transmitting DCI based on at least two PDCCH candidates. The information included in the DCI transmitted by the at least two PDCCH candidates is the same may be understood as the DCI transmitted by the at least two PDCCH candidates being one and the same DCI.
[0083] In the present disclosure, the format of the DCI transmitted by the at least two PDCCH candidates may be DCI format 1_0.
[0084] In the present disclosure, the indexes of at least two PDCCH candidates configured by a network device are the same.
[0085] In the present disclosure, a typical value of the number of PDCCH candidates in the at least two PDCCH candidates configured by the network device is two.
[0086] In one example, in the multi-TRP PDCCH repetition, two PDCCH candidates set by a network device are two SS sets having a link relationship. vs. In response, the indexes of the two PDCCH candidates are the same and are used to transmit one and the same DCI. The DCI includes frequency domain resource allocation information, which indicates the location of a frequency domain resource in a specified bandwidth. death ,The ,specified ,bandwidth ,includes ,RBs ,occupied ,by ,at ,least ,one ,CORESET.
[0087] Two SS sets having a link relationship may be understood as two PDCCH candidates having the same PDCCH candidate index in the two SS sets being used to transmit the same DCI.

Therefore, the present disclosure makes the determination of the frequency domain resource of the PDSCH more versatile, and even when the frequency domain resources of the CORESET corresponding to the two PDCCH candidates used for the PDCCH repetition are different, the frequency domain resource for transmitting the PDSCH is clarified, and the terminal and the network device have the same understanding of the determined frequency domain resource of the PDSCH, thereby improving the transmission performance.
[0089] In an embodiment of the present disclosure, a scheme for determining at least one CORESET included in a specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is described below.
[0090] In one embodiment of the present disclosure, at least one CORESET included in a specified bandwidth corresponding to a frequency domain resource indicated by the frequency domain resource allocation information is determined based on at least two CORESETs associated with at least two SS sets, respectively. The at least two SS sets have a link relationship. The at least two SS sets having the link relationship are determined based on at least two PDCCH candidates set by a network device. vs. There is a correspondence relationship.
[0091] At least one CORESET included in the specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is a specified CORESET among at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0092] In an embodiment of the present disclosure, the specified CORESET is any one of A to D below. A: A CORESET with the smallest CORESET identifier among at least two CORESETs respectively associated with at least two SS sets having a link relationship. B: CORESET corresponding to a specified SS set. The specified SS set is an SS set with the smallest SS set identifier among at least two SS sets having a link relationship. C: A CORESET corresponding to a PRB that occupies the lowest frequency domain position among the designated physical resource blocks (PRBs). The designated PRB is the PRB with the lowest PRB number. The PRB with the lowest PRB number is the PRB with the lowest number among the PRBs included in each CORESET of at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0093] In the present disclosure, the at least two CORESETs may be CORESET#0 and CORESET#1. Here, the PRB with the lowest frequency domain position among the PRBs occupied by CORESET#0 is PRB#i, and the PRB with the lowest frequency domain position among the PRBs occupied by CORESET#1 is PRB#j. If the frequency domain of PRB#i is lower than that of PRB#j, the designated CORESET is CORESET#0; otherwise, the designated CORESET is CORESET#1.
[0094] D: At least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0095] In the present disclosure, in response to the designated CORESET being at least two CORESETs respectively associated with at least two SS sets having a link relationship, the designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information includes all PRBs occupied by the at least two CORESETs respectively associated with the at least two SS sets having a link relationship. The designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information may be understood as including consecutive PRBs from a first PRB to a second PRB. The first PRB is a PRB that occupies the lowest frequency domain position among the PRBs included in the at least two CORESETs, and the second PRB is a PRB that occupies the highest frequency domain position among the PRBs included in the at least two CORESETs.

In the present disclosure, in another aspect, in response to the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship not being consecutive, the consecutive PRBs from the first PRB to the second PRB are PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship, and an interval PRB between the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0097] In another embodiment of the present disclosure, at least one CORESET included in the designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is CORESET 0. In other words, the CORESET included in the designated bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is unrelated to at least two CORESETs respectively associated with at least two SS sets having a link relationship.
[0098] Furthermore, the above frequency domain resource determination method provided by the present disclosure is suitable for non-interleaved virtual resource block-to-physical resource block (VRB-to-PRB) mapping.

The frequency domain resources of the CORESETs corresponding to the two PDCCH candidates used for the PDCCH repetition may be the same or different.
[0100] In the frequency domain resource determination method provided by the present disclosure, in a PDCCH repetition scenario, a bandwidth corresponding to a frequency domain resource indicated by frequency domain resource indication information included in DCI is clarified, and a frequency domain resource for transmitting a PDSCH is determined. Therefore, according to the present disclosure, the determination of the frequency domain resource of the PDSCH becomes more versatile, and even when the frequency domain resources of the CORESET corresponding to the two PDCCH candidates used for the PDCCH repetition are different, the frequency domain resource for transmitting the PDSCH can be clarified, and the transmission performance is improved.
