Description

TECHNICAL FIELD

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

[0002] The continuous emergence of new Internet applications of new generations puts forward higher requirements for wireless communication technology, which drives the continuous evolution of wireless communication technology to meet the needs of applications. 5G New Radio (NR) supports communication between terminals through sidelink (SL, also called direct link) in Release (Rel) 16, and then is enhanced in Rel 17. However, the frequency spectrum used in sidelink communication in Rel 16 and Rel 17 only considers licensed spectrum and dedicated spectrum, and does not support sidelink communication on unlicensed spectrum (shared spectrum). Sidelink communication on shared spectrum needs to meet the requirements of occupied bandwidth (OCB) specified by regulations. For example, regulations in some regions require that when a terminal uses certain shared spectrum for data transmission, the occupied bandwidth (including the bandwidth containing 99% of the signal power) needs to reach 80%-100% of the nominal bandwidth.

Since the second time-frequency resources are not the same time-frequency resources as the first time-frequency resources used by other user equipment, i.e., more candidate time-frequency resources that can cause interference are excluded, the interference caused by the in-band emission can be reduced to a greater extent.

[0061] The embodiments of the present disclosure are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which the same or similar elements are denoted by the same or similar reference numerals throughout the various figures. The embodiments described below are exemplary and are intended to explain the present disclosure, and are not to be understood as limiting the present disclosure.

[0062] As Figure 1As shown, the method for determining resources provided by the embodiments of the present disclosure can be applied to a wireless communication system 100, which can include but is not limited to a network device 101 and a user equipment 102. The user equipment 102 is configured to support carrier aggregation, and the user equipment 102 can be connected to multiple carrier units of the network device 101, including a primary carrier unit and one or more secondary carrier units.

[0063] It should be understood that the above wireless communication system 100 can be applied to both low frequency scenarios and high frequency scenarios. The application scenarios of the wireless communication system 100 include but are not limited to a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a worldwide interoperability for microwave access (WiMAX) communication system, a cloud radio access network (CRAN) system, a future 5th-Generation (5G) system, a new radio (NR) communication system, or a future evolved public land mobile network (PLMN) system, etc.

[0064] The above-mentioned user equipment 102 can be a user equipment (UE), a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, or a user equipment, etc. The user equipment 102 can have a wireless transceiving function, which can communicate (e.g., wirelessly communicate) with one or more network devices 101 of one or more communication systems and accept network services provided by the network device 101, where the network device 101 includes but is not limited to the illustrated base station.

[0065] The user equipment 102 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device having wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a user equipment in a future 5G network, or a user equipment in a future evolved PLMN network, and the like.

[0066] The network device 101 can be an access network device (or an access network site). The access network device refers to a device having a network access function, such as a radio access network (RAN) base station, and the like. The network device can specifically include a base station (BS) device, or include a base station device and a radio resource management device for controlling the base station device, and the like. The network device can also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, and the like. The network device can be a wearable device or a vehicle-mounted device. The network device can also be a communication chip having a communication module.

[0067] For example, the network device 101 includes, but is not limited to, a next generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in an LTE system, a radio network controller (RNC), a node B (NB) in a WCDMA system, a radio controller under a CRAN system, a base station controller (BSC), a base transceiver station (BTS) in a GSM system or a CDMA system, a home base station (for example, a home evolved node B, or a home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, and the like.

[0068] In NRel16, to support NR operation on shared spectrum, the concept of Interlaced Resource Blocks (IRBs) is defined to meet the regulatory requirements for Open Channel Blocks (OCBs). For a 20MHz shared subband, if the subcarrier spacing is 15kHz, one IRB contains 10 non-contiguous PRBs; the interval between two adjacent PRBs within the same IRB is fixed at 10 PRBs; there are a total of 10 IRBs on the 20MHz subband, numbered IRB 0, 1, ..., 9 in frequency order. If the subcarrier spacing is 30kHz, one IRB contains 10 non-contiguous PRBs; the interval between two adjacent PRBs within the same IRB is 5 PRBs; there are a total of 5 IRBs on the 20MHz subband, numbered 0, 1, 2, 3, and 4 in frequency order. If the terminal uses IRBs for data transmission, the OCB requirements can be met.

[0069] On the other hand, due to the nonlinear nature of the transmitter in the transmitting device, in-band leakage occurs. A common model for in-band leakage is... Figure 2 As shown. The interference intensity varies depending on the location of the frequency resources used by the transmitting device at different frequency locations within the band. In direct-connect communication, due to the arbitrary location of different transmitting and receiving terminals, the difference in received power between the interfering signal and the useful signal can be significant. In this case, even if the interfering signal and the useful signal use mutually orthogonal frequency resources, strong interference may still occur due to in-band leakage.

[0070] Therefore, when determining its candidate time-frequency resources, user equipment needs to minimize interference caused by in-band leakage as much as possible.

[0071] This disclosure provides a method for determining resources. Figure 3 This is a flowchart illustrating a method for determining resources according to an exemplary embodiment, such as... Figure 3 As shown, the method includes:

[0072] Step 301: The user equipment receives direct connection control information, which indicates the first time-frequency resource.

[0073] For example, the first user equipment receives sidelink control information (SCI) from the second user equipment, which indicates the first time-frequency resource to be used by the second user equipment. The first time-frequency resource may be a time-frequency resource on a slot within a resource selection window, for example, time-frequency resource m in slot n.

[0074] Exemplarily, the resource indication information in the SCI indicates the first time-frequency resource, or the resource reservation information in the SCI indicates the first time-frequency resource.

[0075] At step 302, based on the sidelink control information, determine the candidate time-frequency resource to be excluded.

[0076] To prevent the interference caused by in-band leakage, the first user equipment excludes the time-frequency resource that can cause greater interference from the candidate time-frequency resources available to it. Among them, the candidate time-frequency resource to be excluded includes the candidate time-frequency resource that has resource overlap with the second time-frequency resource, which has resource overlap with the first time-frequency resource in the time domain and has different resource positions from the first time-frequency resource in the frequency domain. The resource overlap here means that resource overlap occurs in both the frequency domain and the time domain. As can be seen, the second time-frequency resource is a time-frequency resource different from the first time-frequency resource.

[0077] By excluding the candidate time-frequency resource that has resource overlap with the second time-frequency resource from the candidate time-frequency resources available to the user equipment, the interference caused by in-band leakage can be minimized as much as possible.

[0078] In an embodiment of the present disclosure, the candidate time-frequency resource to be excluded also includes the candidate time-frequency resource that has resource overlap with the first time-frequency resource. As can be seen from the above, the first time-frequency resource is the time-frequency resource used by the second user equipment indicated in the SCI sent by the second user equipment, and therefore excluding the candidate time-frequency resource that has resource overlap with the first time-frequency resource can effectively prevent the interference caused by in-band leakage.

[0079] In an embodiment of the present disclosure, the second time-frequency resource includes at least one of the following:

[0080] The frequency domain resource adjacent to the first time-frequency resource in the frequency domain;

[0081] The frequency domain resource at the mirror position of the first time-frequency resource in the frequency domain.

[0082] Generally speaking, given the frequency resources occupied by the transmission, the frequency resources in the adjacent position, the zero frequency position, and the frequency resources in the mirror position have strong in-band leakage. For signals transmitted using interleaved resource blocks, since the frequency resource positions multiplexed by different user equipments are relatively close, the interference caused by in-band leakage is stronger than that caused by continuous spectrum transmission, and it is more likely to cause a situation where a strong signal overwhelms a weak signal in other frequency positions, such as Figure 4 A situation in which UE A is strongly interfered by UE B is shown.

[0083] Therefore, in order to avoid the interference caused by the in-band leakage, the frequency domain resources which are adjacent to the first time-frequency resource in frequency and / or mirror positions of the first time-frequency resource need to be excluded. That is, the second time-frequency resource includes the frequency domain resources adjacent to the first time-frequency resource in the frequency domain, or the second time-frequency resource includes the frequency domain resources at the mirror positions of the first time-frequency resource in the frequency domain, or the second time-frequency resource includes the frequency domain resources adjacent to the first time-frequency resource in the frequency domain and the frequency domain resources at the mirror positions of the first time-frequency resource in the frequency domain.

[0084] Exemplarily, the frequency domain resources described above include PRBs, subchannels, and IRBs.

[0085] In an embodiment of the present disclosure, the user equipment obtains sidelink measurement values corresponding to the SCI listened by the user equipment, and determines the candidate time-frequency resources to be excluded which are resource overlapped with the second time-frequency resource according to the sidelink measurement values and a first threshold value.

[0086] Here, the sidelink measurement values corresponding to the SCI listened by the user equipment refer to the measurement values obtained by the user equipment through sidelink measurement according to the SCI received by the user equipment.

[0087] Exemplarily, the sidelink measurement values are Sidelink-Reference Signal Receiving Power (S-RSRP) measurement values or Received Signal Strength Indicator (RSSI) measurement values. The Sidelink-Reference Signal Receiving Power can be measured based on Physical Sidelink Control Channel (PSCCH) Demodulation Reference Signal (DMRS) or Physical Sidelink Control Channel (PSSCH) DMRS.

[0088] When the sidelink measurement value obtained by the user equipment is greater than the first threshold value, the user equipment determines that the candidate time-frequency resources to be excluded include the candidate time-frequency resources which are resource overlapped with the second time-frequency resource. When the sidelink measurement value obtained by the user equipment is greater than the second threshold value, the user equipment determines that the candidate time-frequency resources to be excluded include the candidate time-frequency resources which are resource overlapped with the first time-frequency resource. The first threshold value is greater than the second threshold value.

[0089] The method for determining the candidate time-frequency resources to be excluded is described as follows:

[0090] If the direct connection measurement value obtained by the first user equipment is greater than a smaller threshold value, namely the second threshold value, it indicates that the direct connection measurement value is small, such as a small S-RSRP measurement value or a small RSSI measurement value. In this case, the time-frequency resources used by the first user equipment cannot overlap with the first time-frequency resources used by the second user equipment to avoid interference. If the direct connection measurement value obtained by the first user equipment is greater than a larger threshold value, namely the first threshold value, it indicates that the direct connection measurement value is large, such as a large S-RSRP measurement value or a large RSSI measurement value. In this case, even if the time-frequency resources used by the first user equipment do not overlap with the first time-frequency resources used by the second user equipment, interference may still occur. Therefore, it is necessary to exclude more candidate time-frequency resources from the candidate time-frequency resource set of the first user equipment, such as frequency resources that are adjacent to or mirror images of the first time-frequency resources in the frequency domain.

[0091] For example, the first threshold value is equal to the second threshold value plus a set compensation value.

[0092] In one embodiment of this disclosure, the first threshold value is determined based on one of the following methods:

[0093] Predefine the first threshold value;

[0094] Pre-configure the first threshold value; and

[0095] The first threshold value is determined based on the configuration or indication of downlink signaling from the network device.

[0096] This disclosure provides a method for determining resources. Figure 5 This is a flowchart illustrating a method for determining resources according to an exemplary embodiment, such as... Figure 5 As shown, the method includes:

[0097] Step 501: The user equipment receives direct connection control information, wherein the direct connection control information indicates the first time-frequency resource;

[0098] Step 502: Based on the direct connection control information, determine the candidate time-frequency resources to be excluded;

[0099] Step 503: Based on the candidate time-frequency resources to be excluded, determine the number of candidate time-frequency resources, wherein the candidate time-frequency resources are the remaining candidate time-frequency resources after deleting the candidate time-frequency resources to be excluded from the candidate time-frequency resource set;

[0100] Step 504: If the number of candidate time-frequency resources is less than a set number threshold, the updated candidate time-frequency resources to be excluded are determined.

[0101] In the above embodiment, the first user equipment receives an SCI from the second user equipment, which indicates the first time-frequency resource used by the second user equipment. The first user equipment obtains the direct connection measurement value corresponding to the SCI it has detected. When the direct connection measurement value is greater than a first threshold, it determines that the candidate time-frequency resources to be excluded include candidate time-frequency resources that overlap with the second time-frequency resource and candidate time-frequency resources that overlap with the first time-frequency resource. The first user equipment deletes the aforementioned candidate time-frequency resources to be excluded from the candidate time-frequency resource set and obtains candidate time-frequency resources. When using the candidate time-frequency resources obtained by the above method for direct communication, interference caused by in-band leakage can be better avoided. However, if the number of candidate time-frequency resources obtained after deleting the candidate time-frequency resources to be excluded is too small, it will affect the first user equipment's use of time-frequency resources. Therefore, if the number of the aforementioned candidate time-frequency resources is less than a set number threshold, it is necessary to update the candidate time-frequency resources to be excluded, that is, reduce some candidate time-frequency resources to be excluded, so as to increase the number of candidate time-frequency resources available to the first user equipment. The set number threshold here can be predefined, pre-configured, or configured by the network device.

[0102] In one embodiment of this disclosure, the updated candidate time-frequency resources to be excluded can be determined using the following method:

[0103] The first threshold value is increased by a set step size, and the direct connection measurement value is greater than the increased first threshold value. The updated candidate time-frequency resources to be excluded are determined, and the number of candidate time-frequency resources is determined based on the updated candidate time-frequency resources to be excluded, until the number of candidate time-frequency resources is greater than or equal to the set number threshold.

[0104] For example, increase the first threshold value by L dB, and then re-accord according to... Figure 3 The method shown identifies candidate time-frequency resources to be excluded, removes the newly identified candidate time-frequency resources from the candidate time-frequency resource set, and obtains candidate time-frequency resources. If the number of candidate time-frequency resources is greater than or equal to a set threshold, the newly identified candidate time-frequency resources are the updated candidate time-frequency resources to be excluded. If the number of candidate time-frequency resources is still less than the set threshold, the first threshold is increased by L dB, and the above operation is repeated until the number of candidate time-frequency resources determined based on the newly identified candidate time-frequency resources is greater than or equal to the set threshold.

[0105] In one embodiment of this disclosure, the updated candidate time-frequency resources to be excluded can be determined using the following method:

[0106] The updated candidate time-frequency resources to be excluded are determined to include only candidate time-frequency resources that overlap with the first time-frequency resource.

[0107] For example, if the first threshold is increased to positive infinity, then in this case, there is no second time-frequency resource. Therefore, the candidate time-frequency resources to be excluded only include candidate time-frequency resources that overlap with the first time-frequency resource.

[0108] For example, the second time-frequency resource is set to an empty set. In this case, the candidate time-frequency resources to be excluded only include candidate time-frequency resources that overlap with the first time-frequency resource.

[0109] Alternatively, when deleting candidate time-frequency resources to be excluded from the candidate time-frequency resource set, candidate time-frequency resources that overlap with the second time-frequency resource are not deleted. Candidate time-frequency resources obtained in this way are equivalent to candidate time-frequency resources obtained when the second time-frequency resource is set to an empty set.

[0110] This disclosure provides a method for determining resources. The method includes:

[0111] The user equipment receives direct connection control information, which indicates a first time-frequency resource; the user equipment performs resource selection or resource reselection for the time-frequency resource used for direct connection data transmission, and determines candidate time-frequency resources to be excluded based on the direct connection control information.

[0119] Based on the same concept as the above-described method embodiments, this disclosure also provides an apparatus for determining resources. This apparatus may possess the functions of a user equipment as described in the above method embodiments and is used to execute the steps performed by the network device as provided in the above embodiments. This function can be implemented in hardware, or in software, or in hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above-described function.

[0120] In one possible implementation, such as Figure 6 The resource determination device 600 shown can serve as a user equipment involved in the above method embodiments and execute the steps performed by the user equipment in the above method embodiments. For example... Figure 6 As shown, the resource determination device 600 may include a transceiver module 601 and a processing module 602, which are coupled to each other. The transceiver module 601 can be used to support the communication device 600 in communication, and the transceiver module 601 may have wireless communication capabilities, such as being able to communicate wirelessly with other communication devices through a wireless air interface.

[0168] Industrial applicability

[0169] To prevent interference caused by in-band leakage, user equipment excludes time-frequency resources that may cause significant interference from its available candidate time-frequency resources; that is, it excludes candidate time-frequency resources that overlap with the second time-frequency resource. Since the second time-frequency resource is not the same time-frequency resource used by other user equipment, more candidate time-frequency resources that may cause interference are excluded, thus reducing interference caused by in-band leakage to a greater extent.
