Description

[Technical field]

[0001] The present disclosure relates to the field of communication technologies, and in particular to a resource determination method, a resource determination device, and a storage medium. [Background technology]

[0002] In the new radio (NR), for example, when the communication frequency band is frequency range 2, the attenuation of the high frequency channel is fast, so it is necessary to use beam transmission and reception to ensure the coverage range. When a network device (e.g., a base station) has multiple transmission and reception points (Transmission Reception Points, TRPs), multiple TRPs can be used to provide services to terminals, including transmitting to terminals using multiple TRPs. Of course, since similar techniques and drawbacks may exist in any generation of communication technology, this disclosure will only use NR as an example, but does not limit the scenes to which the techniques of the embodiments of this disclosure are applied. In the related art, in a method of transmitting a PDCCH using multiple TRPs, a transmission configuration indication (TCI) state for receiving the PDCCH can be set in a terminal, and the TCI state indicates a receiving beam to be used when the terminal receives the PDCCH. For example, a control resource set (CORESET) is set in a terminal, and a TCI state corresponding to the CORESET is set, and the TCI state is the TCI state when receiving a PDCCH on the CORESET resource.

[0003] Here, the feedback information of the terminal for the PDCCH needs to be transmitted by a physical uplink control channel (PUCCH). The PUCCH resource index corresponding to the PDCCH can be determined by using the index of the starting control channel element (CCE) of the CORESET corresponding to the PDCCH and the number of CCEs of the CORESET. Therefore, in the related art, when similar downlink control information is transmitted using multiple PDCCH candidates to realize multiple TRPs, for example, when the PDCCH is repeatedly transmitted, multiple different CORESETs can be set in the terminal. That is, when the same downlink control information is transmitted by the PDCCH candidates of multiple CORESETs, how to determine the index of the PUCCH resource corresponding thereto is a problem to be solved.

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0041] The data transmission method provided by the embodiment of the present disclosure can be applied to the wireless communication system shown in Figure 1. Referring to Figure 1, the wireless communication system includes a terminal and a network device. The terminal is connected to the network device through wireless resources to transmit and receive data.

[0042] The wireless communication system illustrated in Fig. 1 is only a schematic description, and the wireless communication system may further include other network devices not illustrated in Fig. 1, such as a core network device, a wireless relay device, and a wireless forwarding device. The embodiment of the present disclosure does not limit the number of network devices and the number of terminals included in the wireless communication system.

[0043] Further, it is understood that the wireless communication system of the embodiment 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 frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance, etc. Based on factors such as capacity, speed, and time lag of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network, or future evolution network such as 5G network, which is also called New Radio (NR) network. For ease of explanation, this disclosure will refer to a wireless communication network as a network for short.

[0044] Furthermore, the network device according to the present disclosure may also be referred to as a wireless access network device. The wireless access network device may be a base station, an evolved base station (evolved node B, eNB), a femtocell, 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., a gNB in ​​an NR system, or a component or part of a device constituting a base station. In the case of a vehicle network (V 2 X) communication system, the network device may be an in-vehicle device. It should be understood that the specific technology and the specific device form adopted by the network device are not limited in the embodiments of the present disclosure.

[0045] Furthermore, the terminal according to the present disclosure is also called a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device for providing voice and / or data connectivity to a user. For example, the terminal may be a handheld device having a wireless connection function, an in-vehicle device, etc. Currently, some examples of terminals are a mobile phone, a pocket personal computer (PPC), a handheld computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or an in-vehicle device. In addition, in the case of a vehicle network (V2X) communication system, the terminal device may be an in-vehicle device. It should be understood that the specific technology and the specific device form adopted by the terminal are not limited in the embodiments of the present disclosure.

[0046] In the present disclosure, data transmission is performed between a network device and a terminal based on a beam. During data transmission by a beam, a network device (e.g., a base station) can transmit a PDCCH to a terminal using multiple TRPs (multiple TRPs are also called Multi-TRPs). In the related technology, when a network device (e.g., a base station) transmits a PDCCH to a terminal using one TRP, a TCI state for receiving this PDCCH is set in the terminal. For example, the setting method is as follows. That is, a CORESET such as CORESET#1 is set in the terminal, and the TCI state used correspondingly when the terminal receives a PDCCH of this CORESET#1 resource is set to be TCI#1. Then, a search space set (SS set) is set in the terminal and associated with CORESET#1. When the terminal receives a PDCCH on a resource of the SS set, it receives 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 in each CORESET.

[0047] In the present disclosure, data transmission is performed between a network device and a terminal based on a beam. During data transmission by a beam, if a network device (e.g., a base station) uses multiple TRPs (multiple TRPs are also called Multi-TRPs) to transmit a PDCCH to a terminal, different TRPs are transmitted using different beams.

[0048] Furthermore, there are currently various methods to improve the reliability of the PDCCH when multiple TRPs transmit the same PDCCH.

[0049] Method 1: Set two TCI states for one CORESET. Set one SS set to be associated with this CORESET, and this SS set can correspond to two TCI states, or set two SS sets to be associated with the CORESET, and each SS set corresponds to one TCI state.

[0050] Method 2: When one SS set is configured and this SS set is associated with two CORESETs, and each CORESET corresponds to one TCI state, this SS set can correspond to two TCI states.

[0051] Method 3: Two CORESETs are set, a TCI state is set corresponding to each CORESET, and an SS set is individually set to be associated with each of the two CORESETs, i.e., two SS sets are set, and different CORESETs are associated with different corresponding TCI states.

[0052] The above method can realize that Multi-TRP transmits PDCCH, and different TCI states correspond to different TRPs. In the related art, the PUCCH resource index of the PUCCH resource that needs to be used for feedback information of PDCCH can be determined using the index of the starting CCE of CORESET corresponding to PDCCH and the number of CCEs of CORESET. However, for multiple candidate physical downlink control channels (PDCCH candidates) with a connection relationship, when multiple PDCCH candidates correspond to different CORESETs, how to determine the index of the PUCCH resource corresponding to the same downlink control information transmitted by these multiple PDCCH candidates is a problem to be solved. For example, the connection relationship indicates that multiple PDCCH candidates are used for repeated transmission (repetition) of PPDCCH. When PDCCH is repeatedly transmitted, multiple different CORESETs can be set in the terminal. For example, the above method 2 and method 3 use two CORESETs. When the same downlink control information is transmitted using PDCCH candidates corresponding to multiple CORESETs, how to determine the index of the PUCCH resource that the corresponding feedback information needs to use is a problem to be solved.

[0053] Note that, although different beams are used for a plurality of PDCCH candidates, the time domain or frequency domain resources corresponding to these plurality of PDCCH candidates may be the same or different.

[0054] The present disclosure provides a resource determination method, which is a method for determining a target resource index of a PUCCH resource corresponding to a plurality of PDCCH candidates having a connection relationship when transmitting the same downlink control information. Here, a different CORESET and a corresponding different TCI state are associated with each of the plurality of PDCCH candidates having a connection relationship. For example, for two CORESETs that are repeatedly transmitted by the PDCCH, a resource corresponding to a PUCCH resource index corresponding to one of the CORESETs is used. Here, in one embodiment, a PUCCH resource index can be determined based on a parameter of the CORESET, and / or a candidate PUCCH resource can be determined based on a parameter of the CORESET, and a PUCCH resource index can be determined based on a parameter of the candidate PUCCH resource.

[0096] In one example, in the resource determination method provided by the embodiment of the present disclosure, the PUCCH resource parameter corresponding to the second resource index includes a PUCCH format, where in the embodiment of the present disclosure, the PUCCH format is as follows: 1.Format 0: occupies 1-2 symbols and can transmit 1-2 bits; 2.Format 1: occupies 4-14 symbols and can transmit 1-2 bits; 3.Format 2: occupies 1-2 symbols and can transmit 2 or more bits; 4.Format 3: occupies 4-14 symbols and can transmit more than 2 bits. 5.Format 4: Occupies 4-14 symbols and can transmit two or more bits.

[0097] Here, among the PUCCH formats corresponding to the PUCCH resource, the parameters of the PUCCH format include one of format 0, format 1, format 2, format 3, and format 4. The parameters of the PUCCH format further include at least one of a starting symbol position, a number of symbols, an initial cyclic shift, a time domain Orthogonal Cover Code (OCC), a number of PRBs, an OCC length, an OCC index, and an interlace.

[0098] In an embodiment of the present disclosure, in response to the PUCCH resource parameter corresponding to the second resource index including a PUCCH format corresponding to the PUCCH resource, the first resource index is determined by adopting one or a combination of the following manners:

[0099] A), determining a first resource index based on the size of the feedback data amount supported by the PUCCH format of the PUCCH resource corresponding to the second resource index.

[0100] For example, in one example, a PUCCH resource that supports a large amount of feedback data in a PUCCH format can be selected. For example, when a large number of bits need to be transmitted, a PUCCH resource that can support a large amount of feedback data is selected. When a small number of bits need to be transmitted, a PUCCH resource that can support a small amount of feedback data is selected.

[0101] B), determining a first resource index based on the number of symbols occupied by the PUCCH format of the PUCCH resource corresponding to the second resource index.

[0102] For example, in one example, an appropriate PUCCH format can be selected based on a delay requirement, e.g., if the delay requirement is short, a PUCCH format that typically occupies a small number of symbols is selected, and otherwise, a PUCCH format that typically occupies a large number of symbols is selected.

[0103] C) Determine the first resource index based on the aggregation level of DCI signaling carried in the PDCCH candidate and the number of symbols occupied by the PUCCH format of the PUCCH resource corresponding to the second resource index and / or the amount of feedback data supported.

[0104] For example, in one example, an appropriate PUCCH format is selected based on the aggregation level (AL) of the PDCCH. If the AL is large, it indicates good channel conditions, and a PUCCH format with short symbols can be selected. Otherwise, a PUCCH format with long symbols is selected.

[0105] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to a PUCCH resource parameter of a second resource index including a starting symbol position corresponding to a PUCCH resource, a first resource index is determined based on a reception processing period of downlink data scheduled and / or downlink control information indicated by downlink control information carried in the N PDCCH candidates and a starting symbol position corresponding to the PUCCH resource.

[0106] For example, if the terminal needs more time to receive and process the downlink signaling, data, or reference signal transmitted from the base station, it selects a PUCCH resource with a later starting symbol position, otherwise it selects a PUCCH resource with an earlier starting symbol position. Before transmitting feedback information on the PUCCH resource, the terminal should complete the processing procedure of the downlink signaling, data, or reference signal, and complete the transmission preparation procedure of the feedback information to be fed back.

[0107] In one example, in the resource determination method provided by the embodiment of the present disclosure, in response to the PUCCH resource parameter of the second resource index including the number of symbols corresponding to the PUCCH resource, the downlink control information carried in the N PDCCH candidates is determined based on the delay requirement of the downlink data scheduled and / or the downlink control information indicated and the number of symbols corresponding to the PUCCH resource.

[0108] For example, if the delay requirement is short, a PUCCH resource with a small duration, ie, a PUCCH resource with a small number of symbols, is selected; otherwise, a PUCCH resource with a large duration, ie, a PUCCH resource with a large number of symbols is selected.

[0109] In one example, in the resource determination method provided by the embodiment of the present disclosure, in response to the PUCCH resource parameter of the second resource index including an end symbol position corresponding to the PUCCH resource, the downlink control information carried in the N PDCCH candidates is determined based on the delay requirement of the downlink data scheduled and / or the downlink control information indicated and the end symbol position corresponding to the PUCCH resource. However, the end symbol position corresponding to the PUCCH resource is determined based on the start symbol position and the number of symbols.

[0110] For example, if transmission needs to be completed quickly, a PUCCH resource with an earlier end symbol position is selected, and otherwise a PUCCH resource with a later end symbol position is selected.

[0111] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to the PUCCH resource parameter of a second resource index including a PRB offset corresponding to a PUCCH resource, a resource index having a maximum or minimum PRB offset in the second resource index is determined as a first resource index.

[0112] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to a PUCCH resource parameter of a second resource index including an initial cyclic shift corresponding to a PUCCH resource, a resource index having a maximum or minimum initial cyclic shift in the second resource index is determined as a first resource index.

[0113] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to a PUCCH resource parameter of a second resource index including a frequency hopping scheme corresponding to the PUCCH resource, a resource index among the second resource indexes that supports frequency hopping is determined as a first resource index, or a resource index among the second resources that does not support frequency hopping is determined as the first resource index.

[0114] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to the PUCCH resource parameter of a second resource index including a second-hop physical resource block corresponding to a PUCCH resource, a resource index having a maximum or minimum second-hop physical resource block index in the second resource index is determined as a first resource index.

[0115] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to the PUCCH resource parameters of a second resource index including an interlace allocation corresponding to a PUCCH resource, a resource index having a maximum or minimum rb-SetIndex of the interlace allocation at the second resource index is determined as a first resource index.

[0116] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to a PUCCH resource parameter of a second resource index including an interlace allocation corresponding to a PUCCH resource, a resource index having a maximum or minimum subcarrier space (SCS) of the interlace of the interlace allocation in the second resource index is determined as a first resource index.

[0117] In one example, in a resource determination method provided by an embodiment of the present disclosure, in response to the PUCCH resource parameter of a second resource index including a PUCCH format corresponding to a PUCCH resource, a resource index having a maximum or minimum OCC index of the PUCCH format in the second resource index is determined as a first resource index.

[0118] In an example, in a resource determination method provided by an embodiment of the present disclosure, in response to the PUCCH resource parameter of a second resource index including a PUCCH format corresponding to a PUCCH resource, a resource index having a maximum or minimum OCC length of the PUCCH format at the second resource index is determined as a first resource index.

[0119] In an example, in a resource determination method provided by an embodiment of the present disclosure, in response to the PUCCH resource parameter of a second resource index including a PUCCH format corresponding to a PUCCH resource, a resource index having a maximum or minimum number of PRBs of the PUCCH format in the second resource index is determined as a first resource index.

[0120] In the resource determination method provided by the embodiment of the present disclosure, when one PDCCH corresponds to at least two CORESETs, the PUCCH resource determination method is mainly determined based on the configuration reference of one of the CORESETs, or the final target PUCCH resource is determined based on the parameters of each PUCCH resource determined based on the parameters of each CORESET. The present disclosure ensures the consistency of the determined PUCCH resource between the base station and the terminal, and helps the terminal select the optimal PUCCH resource, thereby improving the transmission efficiency of uplink control signaling.

[0121] The resource determination method provided by the embodiments of the present disclosure may include the following main schemes for performing target PUCCH resource determination:

[0122] For example, the terminal determines a target PUCCH resource index, and a PDCCH corresponding to the target PUCCH resource index occupies resources of at least two CORESETs.

[0123] In one example, the terminal determines the target PUCCH resource index based on a configuration parameter of one CORESET of at least two CORESETs.

[0124] In one example, the configuration parameters include at least one of a CORESET index of the CORESET, a CORESETpoolindex index corresponding to the CORESET, an index of a starting CCE, and the number of CCEs included in the CORESET.

[0125] In one example, the terminal determines candidate PUCCH resource indexes corresponding to each CORESET based on configuration parameters of each CORESET among the at least two CORESETs.

[0126] In one example, the configuration parameters of the CORESET for determining the candidate PUCCH resource index include at least one of a CORESET index of the CORESET, a CORESETpoolindex index corresponding to the CORESET, an index of a starting CCE, and the number of CCEs included in the CORESET.
