Description

Resource configuration method, device and storage medium TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of communication, and particularly relates to a resource configuration method, device and storage medium. BACKGROUND

[0002] In a wireless communication system, because beam energy in a near field is more concentrated and the coverage is smaller, for a given target area, a base station equipped with high-frequency extremely large-scale multiple input multiple output (XL-MIMO) needs to use more near-field 3D beams to complete coverage. In order to be able to provide access to user equipment in the coverage range, more Synchronization Signal Block (SSB) beams are needed. When a large number of SSB beams are transmitted in a time division multiplexing (TDM) manner, not only a large amount of wireless resources will be occupied, but also the access time of user equipment will be lengthened.

In addition, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0153] In some embodiments of the present disclosure, since the mid-low frequency spectrum resources are already overcrowded, in order to meet the demand for rising data rates, the academia and industry have begun to explore higher frequency spectrum resources, such as millimeter wave frequency bands, terahertz frequency bands, etc. High frequency transmission will be subject to greater transmission attenuation, especially the absorption of water molecules and oxygen in the air is very serious, so the transmission distance and coverage range are very limited.

[0154] On one hand, higher frequency means shorter wavelength. Compared with mid-low frequency spectrum, more antennas, such as massive antennas or hyper massive antennas, can be deployed under the same aperture size. On the other hand, massive antennas can achieve larger beamforming gain, effectively compensating for severe transmission loss, thereby extending coverage and transmission distance. Therefore, high frequency transmission and massive antenna technology are a pair of complementary technologies. As a combination of the two, XL-MIMO technology is one of the most promising technologies in 6G candidate technologies. It is worth noting that high frequency XL-MIMO will lead to hardening of the wireless channel, mainly dominated by line-of-sight (LoS) propagation.

[0155] In some embodiments, for a given antenna array (whose antenna aperture is denoted as D), its electromagnetic (EM) field can be divided into near field and far field. FIG. IB is a schematic diagram illustrating a division of electromagnetic field according to an embodiment of the present disclosure. As shown in 1B, the boundary between near field and far field is

[0156] The range of the near field depends on the antenna aperture (D) and the wavelength (l). In existing cellular wireless communication systems, user equipment (UE) is mostly located in the far field of the base station (gNB) transmitting antenna array. As mentioned above, if the carrier frequency is getting higher and / or the antenna array is getting larger, the range of the near field will expand. Even if the existing network topology (inter-base station distance, UE distribution, etc.) remains unchanged, the current far field UE is likely to become a near field UE.

[0157] FIG. 1C is a schematic diagram illustrating far and near field beams according to an embodiment of the present disclosure. As shown in FIG. 1C, if the UE is in the far field, the electromagnetic wave received by the UE is a plane wave, and the beam for the UE is a 2 dimension (2D) directional beam pointing to the target UE; if the UE is in the near field, the electromagnetic wave received by the UE is a spherical wave, and the beam for the UE is a 3 dimension (3D) beam surrounding the target UE.

[0158] In the 5G NR system, synchronization signals (SS) are transmitted in the format of SSB burst set. In order to enable the UE to access quickly, the maximum L max ​One synchronization signal block (SS / PBCH block, SSB) needs to be transmitted within 5ms in a time division multiplexing (TDM) manner. Among them, for FR1, the value of L max is 4 or 8; for FR2, the value of L max is 64. One SSB occupies 4 symbols, including PSS, SSS, PBCH and DMRS.

[0159] Moreover, the index of SSB (SSB index) is indicated in two parts. When the maximum number of SSBs is less than or equal to 8, the SSB index is determined based on the index of the DMRS sequence; when the maximum number of SSBs is greater than 8, the lower 3 bits of the SSB index are determined based on the index of the DMRS sequence, and the other bits are carried in the master information block (MIB), i.e. the PBCH contained in the SSB. Therefore, the UE can not only complete cell search, i.e. obtain the cell ID, but also obtain the downlink time domain synchronization by detecting the SSB.

[0160] When the UE and the base station are initially synchronized, the UE detects one of the SSBs transmitted by the base station, obtains the SSB index, and thus knows the symbol position of the SSB, so that the UE and the base station achieve downlink symbol synchronization. In order to achieve uplink synchronization, the UE needs to send a random access preamble (RA preamble), and how to select this preamble and in which RO (RO refers to time-frequency resources) to send it is determined according to the SSB received by the user and which SSBs are actually sent by the base station and the position set of RO.

[0161] In some embodiments, the RO can be determined by the following steps:

[0162] Step 1, the UE detects that the SSB index of the SSB received by itself is SSB#1.

[0163] Step 2, the UE receives a message in which the base station transmits a System Information Block 1 (SIB1) indicating which SSB information the base station actually transmits. The base station uses two 8 bits to indicate which SSBs are actually transmitted. Since the maximum time position of SSB transmission is 64, 64 SSBs are divided into 8 groups, and the 8 SSB positions in each group are continuous. That is, SSB#0~#7 is the first group, SSB#8~15 is the second group,..., and SSB#56~#63 is the eighth group. Then, in the two 8 bits, the first 8 bits indicate which groups have SSB transmission, such as the first 8 bits being 00000001 (left is high bit, right is low bit), which means only the first group has SSB transmission. The second 8 bits indicate which positions of the SSBs in these groups are transmitted, such as the second 8 bits being 10011011, which means SSB#0, #1, #3, #4, and #7 are transmitted in the first group.

[0164] Step 3, through the above steps 1 and 2, the UE knows that the SSB#1 it receives is the second of the five SSBs transmitted by the base station.

[0165] Step 4, the UE receives the SIB1 transmitted by the base station to obtain SSB-perRACH-Occasion information, which identifies how many actually transmitted SSBs a preamble in an RO needs to be allocated to. The value is SSB-perRACH-Occasion{1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16}, when the parameter is 1 / 8, it means that the SSB occupies 8 consecutive ROs. When the parameter is 8, it means that 8 actually transmitted consecutive SSBs share the RO, but use different preambles, such as dividing the 64 preambles into 8 consecutive groups, and each SSB corresponds to one group of preambles. At the same time, the UE receives the SIB1 transmitted by the base station to obtain the number of FDM ROs, which can take one of {1, 2, 4, 8}, if the value is 2, it means that there are two ROs in different frequency domains at the same time. The RO number is first in frequency domain and then in time domain. FIG. 1D is a schematic diagram of an RO according to an embodiment of the present disclosure. If SSB-perRACH-Occasion is 2 and the number of FDM ROs is 2, the RO corresponding to the SSB is as shown in FIG. 1D.

[0166] In some embodiments, since the beam energy in the near field is more concentrated and the coverage is smaller, for a given target area, the base station equipped with XL-MIMO needs to use more near-field 3D beams to complete the coverage. Obviously, for the XL-MIMO array, the L maxA single SSB beam is far from enough. To be able to provide access for UEs in the coverage, more SSB beams are needed. Moreover, the closer to the base station's transmit antenna array, the narrower the SSB beam, and correspondingly, the more SSB beams are needed. If the existing mechanism in the NR system is reused, a large number of SSB beams will be transmitted in a TDM manner.

[0167] In some embodiments, transmitting a large number of SSB beams in a TDM manner not only occupies a large amount of wireless resources, but also causes the SSB burst set period to be long, the time for UE access to wait to be long, i.e., the access to be slow.

[0168] In some embodiments, different beams can transmit SSBs using the same time-domain resources or the same time-frequency domain resources, and the sequences of the Demodulation Reference Signals (DMRSs) corresponding to different SSBs are different to indicate different SSB indexes. However, in this case, how to determine the random access RO and / or preamble resources corresponding to the SSBs transmitted based on the same time-domain resources or time-frequency domain resources is a problem to be solved.

[0169] FIG. 2A is an interaction schematic diagram of a resource configuration method according to an embodiment of the present disclosure. The method can be performed by the communication system described above. As shown in FIG. 2A, the method can include:

[0170] In step S2101, the network device transmits a first reference signal to the terminal device.

[0171] In some embodiments, the terminal device can receive the first reference signal. For example, the terminal device can receive the first reference signal transmitted by the network device. For another example, the terminal device can also receive the first reference signal transmitted by another entity.

[0172] In some embodiments, the first reference signal can be an SSB.

[0173] In some embodiments, the first reference signal can be a DMRS.

[0174] In some embodiments, the network device can transmit multiple reference signals simultaneously.

[0175] In some embodiments, the first reference signal can be one of the multiple reference signals transmitted by the network device simultaneously. For example, the network device can transmit multiple SSBs simultaneously, and the first reference signal is one of the multiple SSBs.

[0176] In some embodiments, the first reference signal can be one of multiple reference signals simultaneously transmitted by the network device. For example, the network device can simultaneously transmit multiple DMRSs, and the first reference signal is one of the multiple DMRSs. That is, the network device can simultaneously transmit one PSS, one SSS, and one PBCH, but multiple DMRSs are simultaneously transmitted.

[0177] In some embodiments, the network device can transmit multiple reference signals at the first transmission time, and the reference signal received by the terminal device is one of the multiple reference signals, referred to as the first reference signal. At least one reference signal in the multiple reference signals other than the first reference signal can be referred to as the second reference signal. In some embodiments, the transmission time is used to represent the time domain resource for transmitting the reference signal.

[0178] In some embodiments, the multiple reference signals simultaneously transmitted by the network device have different identities at the transmission time. The identity can be index, ID, etc., and the embodiments of the present disclosure are not limited in this regard.

[0179] For example, the identity of the first reference signal at the first transmission time is a first identity, the identity of the second reference signal at the first transmission time is a second identity, and the first identity is different from the second identity. The identity of each second reference signal at the first transmission time is also different. Where the first identity corresponding to the first reference signal is different from the second identity corresponding to the second reference signal, it can be understood that the DMRS sequence corresponding to the first reference signal is different from the DMRS sequence corresponding to the second reference signal.

[0180] Step S2102: The terminal device determines an index value corresponding to the first reference signal.

[0181] In some embodiments, the index value can be index, ID, identity, etc., and the embodiments of the present disclosure are not limited in this regard.

[0182] In some embodiments, the index values corresponding to different reference signals are different.

[0183] For example, the index value of the first reference signal transmitted by the network device at the first transmission time is different from the index value of the second reference signal.

[0184] In some embodiments, the index values corresponding to different reference signals being different can also be understood as the index values corresponding to different identity reference signals being different.

[0185] In some embodiments, the index value can include a first bit value and a second bit value, the first bit value can be used to determine a first transmission time corresponding to the first reference signal, and the second bit value can be used to determine a first identity of the first reference signal at the first transmission time, wherein the reference signals transmitted at the first transmission time can include the first reference signal and at least one second reference signal, and a second identity of the second reference signal at the first transmission time is different from the first identity. The first transmission time corresponding to the first reference signal and the second reference signal is the same, that is, the first bit value corresponding to the first reference signal and the second reference signal is the same.

[0186] In some embodiments, the second bit value can be used to determine the first identity of the first reference signal at the first transmission time can be understood as that the second bit value corresponds to the first identity of the first reference signal at the first transmission time. In some examples, there can be two or more reference signals at the first transmission time, and the two or more reference signals correspond to different identities respectively. In other words, the identity corresponding to the reference signal can be used to identify different reference signals transmitted at the same transmission time. In this way, the first identity of the first reference signal at the first transmission time is determined by the second bit value, that is, the first reference signal corresponding to the second bit value at the first transmission time is determined.

[0187] In some embodiments, the identity of the first reference signal at different transmission times can be different.

[0188] In some embodiments, the first bit value can be indicated by a first bit position, and the second bit value can be indicated by a second bit position. FIG. 2B is a schematic diagram of a bit position according to an embodiment of the present disclosure. As shown in FIG. 2B, the shaded square represents the first bit position, the white square represents the second bit position, and the numbers below the squares represent the numbers of the bit positions.

[0189] In some embodiments, the first bit value can be an index value when the bit values of the second bit position are all default values, and the default value can be 0 or 1, which is not limited in the embodiments of the present disclosure.

[0190] In some embodiments, the first bit value can be determined according to at least one of a Demodulation Reference Signal (DMRS), a DMRS sequence, and a MIB in a Physical Broadcast Channel (PBCH), and the specific determination method can refer to the existing protocol, which will not be described here.

[0191] In some embodiments, the terminal device can determine which bit positions to use according to third indication information, which can be a protocol agreement or network device indication.

[0192] In some embodiments, if the first bit position includes K bit positions, the first bit position can represent 2 K bit values, which can be referred to as third bit values, and the first bit value corresponding to the first reference signal is one of the 2 K bit values, and if the second bit position includes J bit positions, the second bit position can represent 2 J bit values, which can be referred to as fourth bit values, and the second bit value corresponding to the first reference signal is one of the 2 J bit values.

[0193] For example, the protocol agrees to use the second bit positions numbered 2, 3, and 4, and there are 8 fourth bit values that can be represented by the bit positions numbered 2, 3, and 4, and the second bit value is one of the 8 fourth bit values.

[0194] In some embodiments, the number of fourth bit values can be understood as the maximum number of reference signals transmitted at the same time.

[0195] In some embodiments, the number of reference signals transmitted at the same time can be less than or equal to the number of fourth bit values that the fourth bit position can indicate.

[0196] In some embodiments, the fourth bit value can correspond to a reference signal one-to-one, and the second bit value corresponding to the first reference signal corresponds to the first reference signal.

[0197] In some embodiments, after the terminal device determines the first index value, it can determine the first transmission time of the first reference signal transmitted by the network device.

[0198] In some embodiments, the first reference signal is a DMRS, and after the terminal device determines the first index value, it needs to combine the index value indicated by the MIB of the PBCH in the SSB to determine the first transmission time of the first reference signal transmitted by the network device.

[0199] In some embodiments, the first reference signal is an SSB, and after the terminal device determines the first index value, it can determine the first transmission time of the first reference signal transmitted by the network device.

[0200] It should be noted that the second bit value can determine the first identifier corresponding to the first reference signal, that is, the second bit value and the first reference signal are a unique correspondence, and the random access resource corresponding to the second bit value in the following is the random access resource corresponding to the first reference signal, and the meanings expressed by the two are the same.

[0201] In step S2103, the network device sends SIB information to the terminal device.

[0202] In some embodiments, the terminal device can receive the SIB information. For example, the terminal device can receive the SIB information sent by the network device. For another example, the terminal device can also receive the SIB information sent by other entities.

[0203] It should be noted that the specific manner in which the network device sends the SIB information can refer to the existing protocol, which will not be described here.

[0204] In step S2104, the terminal device determines first information according to the SIB information.

[0205] In some embodiments, the first information can be used to indicate the first mapping relationship and / or the second mapping relationship.

[0206] In some embodiments, the first mapping relationship can include a mapping relationship between different first bit values and random access resources.

[0207] In some embodiments, the first reference signal is a DMRS, and the first mapping relationship includes a mapping relationship between a first bit value corresponding to a DMRS sequence and a random access resource together with a bit value indicated in a MIB in a PBCH.

[0208] In some embodiments, the random access resource can include at least one of the following: a random access channel occasion (Random access channel occasion, RO), a random access preamble (preamble).

[0209] In some embodiments, different first bit values can correspond to different random access resources.

[0210] In some embodiments, the first mapping relationship can be determined according to SSB-perRACH-Occasion in the SIB information.

[0211] In some embodiments, the first mapping relationship can be understood as a mapping relationship between a first transmission time corresponding to the first bit value and a random access resource, and different transmission times correspond to different random access resources.

[0212] In some embodiments, the first mapping relationship can be a protocol agreement or network device indication.

[0213] In some embodiments, the name of the first mapping relationship is not limited, for example, it can be "correlation", "correspondence" and the like.

[0214] In step S2105, the terminal device determines the first random access resource corresponding to the first bit value according to the first mapping relationship.

[0215] In some embodiments, the first random access resource can include the first RO and / or the first preamble.

[0216] In some embodiments, after the terminal device determines the first mapping relationship, it can determine the random access resource corresponding to the first bit value according to the first mapping relationship, and take the random access resource as the first random access resource corresponding to the first bit value.

[0217] In some embodiments, the first reference signal is DMRS, and after the terminal device determines the first mapping relationship, it can determine the random access resource corresponding to the first bit value together with the bit value indicated by the MIB in the PBCH according to the first mapping relationship, and take the random access resource as the first random access resource corresponding to the first bit value.

[0218] In some embodiments, determining the first random access resource corresponding to the first bit value can be understood as determining the first random access resource corresponding to the plurality of reference signals transmitted by the network device at the first transmission time.

[0219] For example, the first random access resource can be the random access resource corresponding to the first reference signal and the second reference signal.

[0220] In step S2106, the terminal device determines the second random access resource corresponding to the second bit value from the first random access resource according to the second mapping relationship, to obtain the random access resource corresponding to the first reference signal.

[0221] In some embodiments, the second random access resource can include the second RO and / or the second preamble.

[0222] In some embodiments, the second mapping relationship can include the mapping relationship between different second bit values and the first random access resource.

[0223] In some embodiments, different second bit values can correspond to different random access resources in the first random access resource.

[0224] In some embodiments, the first reference signal is DMRS. The second bit value is used to indicate the identity or index corresponding to the DMRS sequence.

[0225] In some embodiments, the second mapping relationship can be understood as a mapping relationship between different reference signals in the multiple reference signals simultaneously sent by the network device and the first random access resource, the different reference signals corresponding to different random access resources in the first random access resource.

[0226] In some embodiments, the second bit value is a first numerical value, the first random access resource can be divided into M parts, and the second random access resource corresponding to the second bit value can be determined as a third random access resource, the third random access resource can include a specified part of the M parts of random access resources.

[0227] In some embodiments, the first numerical value can be 0.

[0228] In some embodiments, if the bit value of each second bit position is 0, it indicates that the second bit value is 0.

[0229] In some embodiments, the result of the second bit value mod 4 can be determined, and the result is 0, indicating that the second bit value is 0.

[0230] It should be noted that the first numerical value can also be another numerical value agreed by the protocol or indicated by the network, and the embodiments of the present disclosure do not limit this.

[0231] In some embodiments, M can be an integer greater than 1, for example, M can be 2, 4, etc., or the number of second bit values.

[0232] In some embodiments, the specified part can be agreed by the protocol or indicated by the network device.

[0233] In some embodiments, the specified part can be determined according to the number of the second bit value.

[0234] In some embodiments, the number of the second bit value can be determined according to the value of the second bit value.

[0235] Optionally, the second bit values can be arranged in ascending order or descending order, and the arrangement number can be used as the number of the second bit value. For example, if the second bit value is indicated by 3 bits, a total of 8 second bit values can be indicated, the number of the smallest second bit value 000 (such as the second bit value with a value of 0) is 0, and the number of the largest second bit value 111 is 7. If the second bit value is 0, the number of the second bit value can be determined as 0.

[0236] In some embodiments, if M is 2, it means that the first random access resource is divided into two parts, and one of the two parts is designated as the second random access resource corresponding to the second bit value, and the second random access resource corresponding to the second bit value is the random access resource corresponding to the first reference signal. For example, if the first random access resource includes two ROs, the first RO and the corresponding preamble can be allocated to the first reference signal, and the second RO and the corresponding preamble can also be allocated to the first reference signal.

[0237] In some embodiments, if the first value is 0, M can be 2, which means that the first random access resource is divided into two parts, and one of the two parts is designated as the second random access resource corresponding to the second bit value, and the second random access resource corresponding to the second bit value is the random access resource corresponding to the first reference signal. For example, if the first random access resource includes two ROs, the first RO and the corresponding preamble can be allocated to the first reference signal, and the second RO and the corresponding preamble can also be allocated to the first reference signal.

[0238] In some embodiments, if M is 4, it means that the first random access resource is divided into four parts, and one of the four parts is designated as the second random access resource corresponding to the second bit value, and the second random access resource corresponding to the second bit value is the random access resource corresponding to the first reference signal. For example, if the first random access resource includes two ROs, one half of the corresponding multiple preambles of the first RO can be allocated to the first reference signal, and one half of the corresponding multiple preambles of the second RO can also be allocated to the first reference signal.

[0239] In some embodiments, the value of M can also be the number of second bit values, which can be the maximum number of bit values that can be indicated by the bit of the second bit value. For example, if the second bit value is indicated by 3 bits, the number of second bit values is 8.

[0240] For example, if the number of second bit values is 8, M is 8, which means that the first random access resource is divided into 8 parts, and one of the 8 parts is designated as the second random access resource corresponding to the second bit value, and the second random access resource corresponding to the second bit value is the random access resource corresponding to the first reference signal. The remaining 7 parts of random access resources can be equally divided among the other 7 second bit values.

[0241] In some embodiments, the value of M can also be less than the number of second bit values. For example, if the second bit value is indicated by 3 bits, the number of second bit values is 8. It is illustrated that at most 8 reference signals can be transmitted at the same time, and the number of actually transmitted reference signals can be less than 8, and the value of M is the number of actually transmitted reference signals at the same time.

[0242] In some embodiments, if the first value is 0, the value of M is set as the number of second bit values, and if the number of second bit values is 8, the value of M is 8, that is, the first random access resource is divided into 8 parts, and a specified part of the 8 parts of random access resources is used as the second random access resource corresponding to the second bit value. The second random access resource corresponding to the second bit value is the random access resource corresponding to the first reference signal. The other 7 second bit values can be divided into the remaining 7 parts of random access resources. The specified part can be determined according to the number of the second bit value, for example, if the second bit value is 0, the specified part is the first part.

[0243] In some embodiments, if the first value is 0, the value of M is set as the first number of actually transmitted reference signals at the same time, and the first number is less than or equal to the number of second bit values. For example, the first number is 4, and the number of second bit values is 8, and the value of M is 4, that is, the first random access resource is divided into 4 parts, and a specified part of the 4 parts of random access resources is used as the second random access resource corresponding to the second bit value. The second random access resource corresponding to the second bit value is the random access resource corresponding to the first reference signal. For example, if the second bit value is indicated by 3 bits, the second bit value of the actually transmitted reference signal at the same time is 000, 011, 101, and 111, and the second bit value of the first reference signal is 011, the first reference signal corresponds to the second part of the 4 parts.

[0244] In some embodiments, it is determined that the second bit value is a second value, the first random access resource is divided into N parts, and it is determined that the second random access resource corresponding to the second bit value is a fourth random access resource. The fourth random access resource can include a specified part of the N parts of random access resources.

[0245] In some embodiments, the second value can be a non-first value, for example, if the first value is 0, the second value can be a non-zero value.

[0246] In some embodiments, N can be an integer greater than 1, for example, N can be 2, 4, etc., or the number of second bit values.

[0247] In some embodiments, the specific method of dividing the first random access resource into N parts can refer to the implementation method of dividing the first random access resource into M parts described above, which will not be repeated here.

[0248] In some embodiments, when M and N are equal to the number of second bit values, it can be understood that the second bit values of the first number and the second bit values of the non-first number are each divided into the first random access resource.

[0249] For example, if the first RO includes 2 ROs and the number of second bit values is 4, the first two second bit values can be allocated a plurality of preambles corresponding to one RO, wherein the reference signal corresponding to each second bit value can be divided into half of the plurality of preambles, and the last two second bit values can be allocated a plurality of preambles corresponding to another RO.

[0250] For another example, if the first RO includes 1 RO and the number of second bit values is 4, the reference signals corresponding to the 4 second bit values are each divided into a plurality of preambles, i.e., the reference signal corresponding to each second bit value is divided into 1 / 4 preambles.

[0251] In some embodiments, when the second bit value is determined to be the second number, the first random access resource is divided into two parts, a specified part of the two parts is divided into L parts, and the second random access resource corresponding to the second bit value is determined to be a fifth random access resource, the fifth random access resource includes a specified part of the L parts of random access resources.

[0252] In some embodiments, L can be an integer greater than 0, for example, L can be 2, 4, etc., or the number of second bit values of the non-first number. For example, if the number of second bit values is Z, then L = Z-1.

[0253] In some embodiments, L is the number of multiple reference signals actually transmitted at the same time minus one, for example, if the number of multiple reference signals actually transmitted at the same time is Z, then L = Z-1. The minus one means that the reference signal of the second bit value of the first number is removed.

[0254] In some embodiments, if L is equal to the number of second bit values of the non-first number (or the second bit value corresponding to the reference signal actually transmitted at the same time as the first reference signal), the first random access resource can be divided into two parts, and the second bit values of the non-first number are each divided into a specified part of the two parts of random access resources. The second random access resource corresponding to the second bit value can be determined according to the number of the second bit value.

[0255] For example, if the first random access resource includes 2 ROs, the number of second bit values (or second bit values corresponding to reference signals actually transmitted at the same time as the transmission time of the first reference signal) is 4, L is 3, the 2 ROs can be divided into two parts, the first preamble of the first RO can be divided into 3 parts, and each non-first value fourth bit value is divided into one of the first preambles. If the number of the second bit value is 1, the second bit value can be divided into the first part of the first preamble.

[0256] It should be noted that the number of second bit values in the present application can be replaced by the number of second bit values corresponding to reference signals actually transmitted at the same time.

[0257] In some embodiments, the first random access resource is first divided into two parts, and a specified one of the two parts is divided into L parts. It can be understood that the value of M is 2, that is, the first random access resource is divided into 2 parts, one part of the random access resource is given to the second bit value of the first value, and the remaining second bit values are divided into the other part of the random access resource, that is, the other part of the random access resource is divided into L parts, and each non-first value second bit value is divided into one of the L parts of the random access resource.

[0258] For example, if the first random access resource includes 2 ROs, the number of second bit values is 4, and L is 3, the 2 ROs can be divided into two parts, the first RO is given to the second bit value with a value of 0, and the second preamble of the second RO is divided into 3 parts, and each non-0 second bit value is divided into one of the second preambles.

[0259] By using the above method, the terminal device can determine the first random access resource according to the first bit value, determine the second random access resource corresponding to the second bit value from the first random access resource, and obtain the random access resource corresponding to the first reference signal. In this way, when the network device simultaneously transmits multiple reference signals, the terminal device can determine the random access resource corresponding to the reference signal, thereby improving the success rate of random access.

[0260] The method related to the embodiments of the present disclosure can include at least one of the steps S2101-S2106. For example, the step S2101 can be implemented as an independent embodiment, the step S2102 can be implemented as an independent embodiment, the step S2103 can be implemented as an independent embodiment, the step S2105 can be implemented as an independent embodiment, the step S2106 can be implemented as an independent embodiment, the step S2101+the step S2102 can be implemented as an independent embodiment, the step S2103+the step S2104 can be implemented as an independent embodiment, the step S2105+the step S2106 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0261] In some embodiments, the order between any two of the steps S2101-S2106 can be exchanged or performed simultaneously.

[0262] In some embodiments, the steps S2101-S2106 are optional, and one or more of the steps can be omitted or replaced in different embodiments. For example, the step S2103 can be omitted.

[0263] In some embodiments, other optional implementations described before or after the description corresponding to FIG. 2A can be referred to.

[0264] FIG. 2C is an interaction schematic diagram of a resource configuration method according to an embodiment of the present disclosure. The method can be performed by the communication system described above. As shown in FIG. 2C, the method can include:

[0265] In step S2301, the network device sends a first reference signal to the terminal device.

[0266] The optional implementation of the step S2301 can be referred to the optional implementation of the step S2101 of FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which will not be described herein again.

[0267] In step S2302, the terminal device determines an index value corresponding to the first reference signal.

[0268] The optional implementation of the step S2302 can be referred to the optional implementation of the step S2102 of FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which will not be described herein again.

[0269] In step S2303, the network device sends SIB information to the terminal device.

[0270] The optional implementation of the step S2303 can be referred to the optional implementation of the step S2103 of FIG. 2A and other associated parts in the embodiments related to FIG. 2A, which will not be described herein again.

[0271] Step S2304, the terminal device determines the first information according to the SIB information.

[0272] In some embodiments, the first information can be used to indicate a third mapping relationship.

[0273] In some embodiments, the third mapping relationship can include a mapping relationship between different index values and random access resources.

[0274] Step S2305, according to the index value and the third mapping relationship, a sixth random access resource is determined from the random access resources, to obtain a random access resource corresponding to the first reference signal.

[0275] In some embodiments, the random access resources can be divided into X*Y parts, and the sixth random access resource can include a specified part of the X*Y parts of random access resources.

[0276] In some embodiments, X is related to the number of third bit values, and Y is related to the number of fourth bit values.

[0277] In some embodiments, X represents the number of third bit values or the number of third bit values corresponding to the actually transmitted reference signals, and Y represents the number of fourth bit values or the number of fourth bit values corresponding to the actually transmitted reference signals, the third bit value includes a bit value that can be represented by a first bit position, the first bit position includes a bit position used to indicate the first bit value, the fourth bit value includes a bit value that can be represented by a second bit position, the second bit position includes a bit position used to indicate the second bit value.

[0278] In some embodiments, the number of third bit values corresponding to the actually transmitted reference signals can be understood as the number of transmission times of the actually transmitted SSBs.

[0279] In some embodiments, the number of fourth bit values corresponding to the actually transmitted reference signals can be understood as the number of actually transmitted reference signals on each transmission time. For example, if 4 reference signals are transmitted on the first transmission time, the value of Y is 4.

[0280] For example, if the first bit value is represented by bit positions numbered 6 and 7, the value of X is less than or equal to 4; if the second bit value is represented by bit positions numbered 2, 3, and 4, the value of Y is less than or equal to 8.

[0281] For example, if the number of third bit values corresponding to the actually transmitted reference signals is 4 and the number of fourth bit values is 8, the random access resources can be divided into 32 (4*8) parts, and the sixth random access resource is a specified part of the 32 parts.

[0282] In some embodiments, the first part of the 32 random access resources can be determined according to the number of the index value, for example, if the number of the index value is 0, the first part of the 32 random access resources can be the sixth random access resource.

[0283] In some embodiments, the second bit value is determined to be the first value, the random access resources are divided into X parts, a specified part of the X random access resources is the seventh random access resource, the seventh random access resource is divided into two parts, and a specified part of the two random access resources is the sixth random access resource.

[0284] In some embodiments, the random access resources are divided into X parts, which means that the random access resources are divided according to the number of the third bit value, that is, each transmission time corresponds to a part of the random access resources.

[0285] In some embodiments, the seventh random access resource is divided into two parts, and a specified part of the two random access resources is the sixth random access resource, which can be understood as that the fourth bit value of the first value occupies half of the random access resources corresponding to the transmission time.

[0286] For example, if the random access resources include 4 ROs, the value of X is 4, and the value of Y is 8, the 4 ROs are first divided into 4 parts, one RO is one part, and a specified part is the seventh random access resource. Among them, the specified part can be determined according to the number of the first bit value, for example, if the number of the first bit value is 0, the specified part is the first part, that is, the first RO.

[0287] If the seventh random access resource is the first RO, the first RO can be divided into 2 parts, that is, the multiple preambles corresponding to the first RO are divided into two parts, and the second bit value is assigned to a specified part of the two preambles. Among them, the specified part can be determined according to the number of the second bit value, for example, if the second bit value is 0, the specified part is the first part.

[0288] In some embodiments, the second bit value is determined to be the second value, the random access resources are divided into X parts, a specified part of the X random access resources is the seventh random access resource, the seventh random access resource is divided into two parts, a specified part of the two random access resources is the eighth random access resource, the eighth random access resource is divided into Y parts, and a specified part of the Y random access resources is the sixth random access resource.

[0289] In some embodiments, the seventh random access resource represents the random access resource corresponding to the first transmission time of the network device sending the first reference signal.

[0290] In some embodiments, the eighth random access resource is divided into Y parts, and a specified part of the Y parts of random access resources is the sixth random access resource, indicating that the fourth bit values of the non-first values are divided into the eighth random access resource, i.e., after the fourth bit values of the first values are divided into a specified part of the seventh random access resource, the fourth bit values of the non-first values are divided into the remaining part of the seventh random access resource.

[0291] For example, if the random access resource includes 4 ROs, the value of X is 4, and the value of Y is 4, the 4 ROs are first divided into 4 parts, and one RO is one part. A specified part is used as the seventh random access resource. Among them, the specified part can be determined according to the number of the first bit value, such as the number of the first bit value is 0, and the specified part is the first RO.

[0292] If the seventh random access resource is the first RO, the plurality of preambles corresponding to the first RO can be divided into two parts, such as the first preamble corresponding to the first RO includes 6 preambles, the 6 preambles can be divided into 2 parts, each part of the preamble includes 3 preambles, and a specified part of the preamble is used as the eighth random access resource. Among them, the specified part can be determined according to the number of the second bit value, such as the second bit value is 0, the specified part is the first part, and the second bit value is non-0, the specified part is the second part.

[0293] If the eighth random access resource is the second preamble, i.e., the last 3 preambles, the last 3 preambles can be divided into 3 parts, and 1 preamble is 1 part. Each fourth bit value of the non-first value is divided into a specified 1 preamble. The specified part of the second bit value can be determined according to the number of the second bit value, such as the second bit value is 1, the specified part is the first part, i.e., the sixth random access resource is the fourth preamble corresponding to the first RO.

[0294] By using the above method, the terminal device can determine the random access resource corresponding to the first reference signal according to the number of the third bit value and the number of the fourth bit value. In this way, when the network device simultaneously sends multiple reference signals, the terminal device can determine the random access resource corresponding to the reference signal, thereby improving the success rate of random access.

[0295] The method related to the embodiments of the present disclosure can include at least one of the steps S2301-S2305. For example, the step S2301 can be implemented as an independent embodiment, the step S2302 can be implemented as an independent embodiment, the step S2303 can be implemented as an independent embodiment, the step S2304 can be implemented as an independent embodiment, the step S2305 can be implemented as an independent embodiment, the step S2301+the step S2302 can be implemented as an independent embodiment, the step S2303+the step S2304 can be implemented as an independent embodiment, the step S2302+the step S2305 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0414] In some embodiments, the above method can include the method described in the embodiments of the above communication system, terminal device, network device, etc., which will not be repeated here.

[0415] In some embodiments, a mapping method of SSB and random access resource for near field is proposed, so that the terminal can inform the network device that the terminal is in the coverage range of the transmission beam corresponding to which SSB through the random access resource, so that the network device can send the random access feedback to the terminal based on the same quasi co-located (QCL) information of the SSB, thereby improving the success rate of random access.

[0416] In some embodiments of the present disclosure, a resource configuration method is provided, which can include at least one of the following embodiments:

[0417] Embodiment 1, the terminal receives a first reference signal, obtains an index value corresponding to the first reference signal, and obtains a random access RO and / or preamble corresponding to the reference signal based on the index value corresponding to the first reference signal.

[0418] Embodiment 2, based on Embodiment 1, the index value corresponding to the first reference signal includes two parts, as shown in FIG. 2B, the first part includes the first bit value corresponding to the first bit position of the shaded square in FIG. 2B; the second part includes the second bit value corresponding to the second bit position of the white square in FIG. 2B.

[0419] Embodiment 3, based on Embodiment 2, the terminal obtains the random access RO and / or preamble corresponding to the first reference signal based on the index value corresponding to the first reference signal, including two methods:

[0420] Method 1:

[0421] The terminal receives the mapping relationship between the first bit value of the first reference signal sent by the network device and the random access RO and / or preamble, and obtains the first random access RO and / or the first preamble corresponding to the first bit value.

[0422] Optionally, the first bit value is the SSB index obtained when the above white square part is all 0 or all 1 by default. The RO and preamble corresponding to the SSB index can be determined based on the SSB-perRACH-Occasion given by the SIB information in the traditional method. That is, the first RO and / or the first preamble is determined based on the first bit value.

[0423] Further, the terminal obtains the second random access RO and / or the second preamble corresponding to the second bit value based on the mapping relationship between the second bit value of the first reference signal sent by the network device and the first random access RO and / or the first preamble (the mapping relationship can also be agreed by the protocol).

[0424] Wherein, confirming the second bit value can include the following two cases:

[0425] Case 1: the terminal confirms that the second bit value is all 0.

[0426] In this case, the SSB index corresponding to the second bit value corresponds to a far-field beam. If the number of second bits is N, that is, N white squares are used (used means that each bit in the N white squares can be set to 1, such as the white squares numbered 2, 3, and 4 are used, N=3), the second bit value can have 2^N in this case, that is, N=3, the second bit value has 8. Therefore, when the terminal monitors that all the white squares are 0, the RO and preamble corresponding thereto are 1 / 2^N resources or 1 / 2 resources in the first RO and the first preamble.

[0427] Wherein, 1 / 2^N indicates that the second bit value and the other 2^N-1 second bit values equally divide the first RO and the first preamble, 1 / 2 indicates that the second bit value uses half of the first RO and the first preamble, and the other 2^N-1 second bit values equally divide the other half. Because the second bit value of all 0 is a far-field user, the number of covered users is more.

[0428] It should be noted that 1 / 2 indicates that the resource of the far-field beam is more, and whether it is half is not limited by the embodiments of the present disclosure, and can be other values.

[0429] Case 2: The terminal monitors that there is a non-0 on the second bit value.

[0430] In this case, the RO and preamble corresponding to the second bit value are 1 / (2^N-1) resources or 1 / (2(2^N-1)) resources in the first RO and the first preamble.

[0431] Wherein, 1 / (2^N-1) indicates that the second bit value of all 0 and the other 2^N-1 second bit values equally divide the first RO and the first preamble, for example, the first RO contains 2 ROs, N=2 (there are a total of 4 second bit values), then the first 2 second bit values divide one RO corresponding to the first preamble (each second bit value corresponds to half of the multiple preambles in the first preamble), and the last two second bit values divide another RO corresponding to the first preamble. If the first RO contains only one RO, then the SSBs corresponding to the 4 second bit values equally divide the multiple preambles in the first preamble, that is, each second bit value divides 1 / 4 of the first preamble.

[0432] 1 / (2(2^N-1)) can be understood as: the second bit value of all 0 takes away half of the first RO and the first preamble, and the remaining 2^N-1 second bit values equally divide the remaining half of the first RO and the first preamble.

[0433] Method 2:

[0434] The terminal receives the mapping relationship between the index value of the first reference signal sent by the network device and the random access RO and / or preamble, and obtains the random access RO and / or preamble corresponding to the index value.

[0435] For example, the second bit value is 4 values, that is, the case where the white square only uses 2 bits.

[0436] In some embodiments, SSB index mod 4, where the SSB index with mod 4 value of 0 is the SSB index with all 0s in the second bit value in Method 1 above, and others have at least one non-0 SSB index. Further RO and preamble determination method is the same as Method 1.

[0437] In some embodiments, the smallest SSB index among the simultaneously transmitted SSB indexes is the SSB index with all 0s in the second bit value in Method 1 above, and others have at least one non-0 SSB index. Further RO and preamble determination method is the same as Method 1.

[0438] In some embodiments of the present disclosure, a communication system is provided, which can include a terminal device and a network device, wherein the terminal device can perform the resource configuration method performed by the terminal device in the foregoing embodiments of the present disclosure; and the network device can perform the resource configuration method performed by the network device in the foregoing embodiments of the present disclosure.
