Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and particularly to a method, an apparatus, and a storage medium for determining frequency domain resources.

Background Art

[0002] In new radio (NR), for example, when the communication bandwidth is in frequency range 2 (FR2), since high-frequency channels rapidly attenuate, beam-based transmission and reception are required to ensure coverage. When a network device (such as a base station) has multiple transmission reception points (TRPs), services can be provided to a terminal using multiple TRPs, including transmitting a physical downlink control channel (PDCCH) to the terminal using multiple TRPs.

[0003] In related technologies, when performing PDCCH transmission using multiple TRPs, two control resource sets (CORESETs) can be configured, and a transmission configuration indicator (TCI) state corresponding to each CORESET can be configured. One TCI state is configured to correspond to each CORESET, and a search space set (SS set) associated with each of the two CORESETs is configured respectively. That is, two SS sets having a link relationship, which are associated with different CORESETs and correspond to different TCI states, are configured. The two SS sets having a link relationship may be understood as being used for two physical downlink control channel (PDCCH) candidates with the same PDCCH candidate resource index in the two SS sets to transmit one downlink control information (DCI).

[0041] In this specification, exemplary embodiments are described in detail and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings refer to the same or similar elements. 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 embodiments 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 via wireless resources and performs data transmission and reception.

[0043] It should be understood that the wireless communication system shown in FIG. 1 is merely a schematic illustration, and although not shown in FIG. 1, the wireless communication system may include other network devices such as a core network device, a wireless relay device, and a wireless backhaul device. In the embodiments 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 embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can 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 FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance, etc. According to factors such as the capacity, speed, and delay of different networks, the network can be classified into 2G (generation) networks, 3G networks, 4G networks, or future evolved networks such as 5G networks, also known as New Radio (NR). For the convenience of description, in the present disclosure, the wireless communication network may sometimes be simply referred to as a network.

[0045] Furthermore, the network device according to the present disclosure may be referred to as a wireless access network device. The wireless 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 wireless relay node, a wireless 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. In the case of a vehicle-to-everything (V2X) communication system, the network device may be an in-vehicle device. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms used by the network device are not limited.

[0046] Furthermore, the terminal according to the present disclosure may be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides a connection of voice and / or data 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, 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 in the embodiments of the present disclosure, the specific technologies and specific device forms used by the terminal are not limited.

[0047] In the present disclosure, data transmission is performed based on beams between a network device and a terminal. In the process of performing data transmission based on beams, a network device (such as a base station) uses a plurality of TRPs (a plurality of TRPs are also called Multi-TRP) to transmit PDCCH to a terminal. In the related art, when a network device (such as a base station) uses one TRP to transmit PDCCH to a terminal, a TCI state for receiving the PDCCH is set for the terminal. For example, in the setting method, one CORESET, for example, CORESET#1, is set for the terminal, and a TCI state used correspondingly when the terminal receives the PDCCH in the CORESET#1 resource is set as TCI#1. Further, one search space set (SS set) associated with CORESET#1 is set for the terminal. When the terminal receives the PDCCH on the resource in the SS set, reception is performed using the beam corresponding to TCI#1. Currently, each SS set can be associated with only one CORESET, and only one TCI state (the TCI state is also called the TCI state) is set for each CORESET.

[0048] In the present disclosure, data transmission is performed based on beams between a network device and a terminal. In the process of performing data transmission based on beams, when a network device (such as a base station) uses a plurality of TRPs (a plurality of TRPs are also called Multi-TRP) to transmit PDCCH to a terminal, different TRPs use different beams for transmission. The plurality of TRPs can transmit the same PDCCH.

[0049] In order to enable multiple TRPs to transmit the same PDCCH, currently, there is a method of configuring two CORESETs, associating one TCI state with each CORESET, and configuring an SS set associated with each of the two CORESETs. That is, two SS sets associated with different CORESETs and corresponding to different TCI states are configured. There is also an association relationship between the PDCCH candidates of the two SS sets with an association relationship. For example, if SS set #1 is associated with SS set #2, PDCCH candidate #i in SS set #1 is associated with PDCCH candidate #i in SS set #2, that is, two PDCCH candidates with the same index are used for transmitting the same DCI, that is, the information of the DCI transmitted by the two PDCCH candidates is the same.

[0050] One application scenario where multiple TRPs transmit the same PDCCH is Multi-TRP PDCCH repetition. In Multi-TRP PDCCH repetition, two CORESETs are configured, and the TCI state corresponding to the CORESET is configured. One TCI state is configured corresponding to each CORESET, and two SS sets with a link relationship, which are associated with different CORESETs and correspond to different TCI states, are configured. The two SS sets with a link relationship may be understood as two PDCCH candidates with the same PDCCH candidate index in the two SS sets being used to transmit the same DCI, that is, the information of the DCI transmitted by the two PDCCH candidates is the same.

[0054] FIG. 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 at least two SS sets having a link relationship and pair having a response relationship, and the at least two PDCCH candidates carry DCI and , the DCI includes frequency domain resource allocation information, and the frequency domain resource allocation information indicates the position of the frequency domain resources in the specified bandwidth pair , the specified bandwidth includes RBs occupied by at least one CORESET.

[0056] In step S12, based on the frequency domain resource allocation information, the frequency domain resources for transmitting the PDSCH are determined.

[0057] In the present disclosure, the fact that at least two PDCCH candidates are used to carry DCI may be understood as transmitting DCI based on at least two PDCCH candidates. Here, the information included in the DCI transmitted by at least two PDCCH candidates is the same, and the DCI transmitted by at least two PDCCH candidates may be understood as one same DCI.

[0058] In the present disclosure, the format of the DCI transmitted by 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 the terminal are the same.

[0060] In the present disclosure, at least two monitored PDCCH candidates may be understood as corresponding PDCCH candidates in the Multi-TRP PDCCH repetition scenario.

[0061] In the present disclosure, a typical value of the number of PDCCH candidates in at least two PDCCH candidates monitored by the terminal is two.

[0062] In one example, in Multi-TRP PDCCH repetition, the terminal monitors two PDCCH candidates, and these two PDCCH candidates correspond to two SS sets having a link relationship and pair and the indexes of the two PDCCH candidates are the same and are used to transmit the same DCI. The DCI includes frequency domain resource allocation information, and the frequency domain resource allocation information indicates the position of the frequency domain resources in the specified bandwidth pair and the specified bandwidth includes the RBs occupied by at least one CORESET.

[0063] Two SS sets having a link relationship may be understood as two PDCCH candidates with 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 PDSCH based on frequency-domain resource allocation information, the frequency-domain resource indicated by the frequency-domain resource allocation information is mapped to designated RBs included in a designated bandwidth, and the designated RBs can be determined as the frequency-domain resources for transmitting PDSCH. The designated bandwidth includes RBs occupied by at least one CORESET.

[0065] In the present disclosure, DCI carried by at least two PDCCH candidates monitored by a terminal includes frequency-domain resource allocation information, and the frequency-domain resource indication information is used to indicate the position of the frequency-domain resource in a designated bandwidth, and the designated bandwidth includes RBs occupied by at least one CORESET. Thereby, the terminal determines a frequency-domain resource for transmitting PDSCH based on the frequency-domain resource indication information. Therefore, according to the present disclosure, the determination of the frequency-domain resource of PDSCH becomes more versatile, and even when the frequency-domain resources of the CORESETs corresponding to the two PDCCH candidates used for PDCCH repetition are different, the frequency-domain resource for transmitting PDSCH can be clarified, and the transmission performance is improved.

[0066] In an embodiment of the present disclosure, a method for determining at least one CORESET included in a designated bandwidth corresponding to the frequency-domain resource indicated by the frequency-domain resource allocation information will be 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 frequency domain resource allocation information is determined based on at least two CORESETs respectively associated with at least two SS sets. The at least two SS sets have a link relationship. The at least two SS sets having a link relationship are at least two PDCCH candidates monitored by a terminal and pair have a response relationship.

[0068] At least one CORESET included in a specified bandwidth corresponding to a frequency domain resource indicated by frequency domain resource allocation information is the 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 the following A to D. A: The CORESET with the smallest CORESET identifier among at least two CORESETs respectively associated with at least two SS sets having a link relationship. B: The CORESET corresponding to the specified SS set. The specified SS set is the SS set with the smallest SS set identifier among at least two SS sets having a link relationship. C: The CORESET corresponding to the PRB with the lowest occupied frequency domain position among the specified physical resource blocks (PRBs). The specified 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, at least two CORESETs may be CORESET#0 and CORESET#1. Here, among the PRBs occupied by CORESET#0, the PRB with the lowest frequency domain position is PRB#i, and among the PRBs occupied by CORESET#1, the PRB with the lowest frequency domain position 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 the PRBs occupied by 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 may be understood to include consecutive PRBs from the first PRB to the second PRB. The first PRB is the PRB with the lowest occupied frequency domain position among the PRBs included in at least two CORESETs, and the second PRB is the PRB with the highest occupied frequency domain position among the PRBs included in at least two CORESETs.

[0073] In one aspect of the present disclosure, in response to the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship being continuous or overlapping, the continuous 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. FIG. 3 shows a schematic diagram of the PRBs occupied by the frequency domain resources according to an exemplary embodiment of the present disclosure. Referring to FIG. 3, the continuous PRBs from the first PRB to the second PRB are the bandwidth occupied by the frequency domain resources for transmitting PDSCH.

[0074] In another aspect of the present disclosure, 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 continuous, the continuous 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 PRBs between the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship. FIG. 4 shows a schematic diagram of the PRBs occupied by the frequency domain resources according to an exemplary embodiment of the present disclosure. Referring to FIG. 4, the continuous PRBs including the interval PRBs from the first PRB to the second PRB are the bandwidth occupied by the frequency domain resources for transmitting PDSCH.

[0075] In another embodiment of the present disclosure, at least one CORESET included in the specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is CORESET0. In other words, the CORESET included in the specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is independent of the 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 the terminal performs PDCCH repetition, DCI format 1_0 is carried on the PDCCH, and the frequency domain bandwidth for transmitting the PDSCH may be the frequency domain bandwidth corresponding to CORESET #0, or may be a specified bandwidth determined based on at least two CORESETs respectively associated with at least two SS sets. 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 the terminal performs PDCCH repetition, the bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource indication information included in the DCI is clarified, and the frequency domain resource for transmitting the PDSCH is determined. Therefore, according to the present disclosure, the determination of the frequency domain resource of the PDSCH becomes more generalizable, and even when the frequency domain resources of the CORESETs corresponding to the two PDCCH candidates used for PDCCH repetition are different, the frequency domain resource for transmitting the PDSCH can be clarified, and the transmission performance is improved.

[0079] Based on the same idea, the embodiments of the present disclosure further provide a frequency domain resource determination method applicable to a network device.

[0080] FIG. 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 set, and the at least two PDCCH candidates have a link relationship with at least two SS sets and pair have a response relationship, and the at least two PDCCH candidates carry DCI and , the DCI includes frequency domain resource allocation information, and the frequency domain resource allocation information indicates the position of the frequency domain resources in the specified bandwidth pair , the specified bandwidth includes the RBs occupied by at least one CORESET.

[0082] In the present disclosure, the fact that at least two PDCCH candidates are used to carry DCI may be understood as transmitting DCI based on the at least two PDCCH candidates. The fact that 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 the at least two PDCCH candidates set by the network device are the same.

[0085] In the present disclosure, a typical value of the number of PDCCH candidates in at least two PDCCH candidates set by a network device is two.

[0086] In one example, in Multi-TRP PDCCH repetition, the two PDCCH candidates set by the network device are two SS sets having a link relationship and pair correspond, the indexes of the two PDCCH candidates are the same, and are used to transmit the same DCI. The DCI includes frequency domain resource allocation information, and the frequency domain resource allocation information indicates the position of the frequency domain resources in the specified bandwidth pair , the specified bandwidth includes the RBs occupied by at least one CORESET.

[0087] The two SS sets having a link relationship may be understood as that two PDCCH candidates with the same PDCCH candidate index in the two SS sets are used to transmit the same DCI.

[0088] In the present disclosure, DCI carried by at least two PDCCH candidates set by a network device includes frequency domain resource allocation information. The frequency domain resource indication information is used to indicate the position of frequency domain resources in a specified bandwidth, and the specified bandwidth includes RBs occupied by at least one CORESET. Thereby, the terminal determines the frequency domain resources for transmitting PDSCH based on the frequency domain resource indication information. Therefore, according to the present disclosure, the determination of the frequency domain resources of PDSCH becomes more versatile.

[0089] In an embodiment of the present disclosure, a method for determining at least one CORESET included in a specified bandwidth corresponding to the frequency domain resources indicated by the frequency domain resource allocation information will be described below.

[0090] In one embodiment of the present disclosure, at least one CORESET included in a specified bandwidth corresponding to the frequency domain resources indicated by the frequency domain resource allocation information is determined based on at least two CORESETs respectively associated with at least two SS sets. The at least two SS sets have a link relationship. The at least two SS sets having the link relationship are at least two PDCCH candidates set by the network device and pair have a corresponding relationship.

[0091] At least one CORESET included in a specified bandwidth corresponding to a frequency domain resource indicated by frequency domain resource allocation information is the 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 the following A to D. A: The CORESET with the smallest CORESET identifier among at least two CORESETs respectively associated with at least two SS sets having a link relationship. B: The CORESET corresponding to the specified SS set. The specified SS set is the SS set with the smallest SS set identifier among at least two SS sets having a link relationship. C: The CORESET corresponding to the PRB with the lowest occupied frequency domain position among the specified physical resource blocks (PRBs). The specified 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. When the frequency domain of PRB#i is lower than that of PRB#j, the specified CORESET is CORESET#0, and otherwise, the specified 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 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 may be understood to include consecutive PRBs from the first PRB to the second PRB. The first PRB is the PRB with the lowest occupied frequency domain position among the PRBs included in at least two CORESETs, and the second PRB is the PRB with the highest occupied frequency domain position among the PRBs included in at least two CORESETs.

[0096] 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 the PRBs occupied by at least two CORESETs respectively associated with at least two SS sets having a link relationship. 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 PRBs 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 specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is CORESET0. In other words, the CORESET included in the specified bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource allocation information is independent of 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.

[0099] According to the above frequency domain resource determination method provided by the present disclosure, in the PDCCH repetition scenario, the DCI format 1_0 is carried on the PDCCH, and the frequency domain bandwidth for transmitting the PDSCH may be the frequency domain bandwidth corresponding to CORESET#0, or may be the specified bandwidth determined based on at least two CORESETs respectively associated with at least two SS sets. The frequency domain resources of the CORESETs corresponding to the two PDCCH candidates used for PDCCH repetition may be the same or different.

[0100] In the frequency domain resource determination method provided by the present disclosure, in the PDCCH repetition scenario, the bandwidth corresponding to the frequency domain resource indicated by the frequency domain resource indication information included in the DCI is clarified, and the frequency domain resource for transmitting the 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 CORESETs corresponding to the two PDCCH candidates used for PDCCH repetition are different, the frequency domain resource for transmitting the PDSCH can be clarified, and the transmission performance is improved.
