[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202410626386.0 filed on May 20, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and specifically relates to a resource determination method, device, equipment and storage medium. BACKGROUND

[0004] Network energy saving is of great importance to environmental sustainability, reduction of environmental impact, and savings in operating costs. As 5G becomes popular in various industries and regions, handling more advanced services and applications that require very high data rates, networks become more dense, using more antennas, larger bandwidths, and more frequency bands. The environmental impact of 5G needs to be kept under control, and new solutions need to be developed to improve network energy saving.

[0005] The power consumption of the current wireless access can be divided into two parts: the dynamic part is consumed only when data transmission or reception is performed, and the static part is always consumed to maintain the operation of the wireless access device, even when data transmission or reception is not being performed. Therefore, how to minimize the power consumption of the static part is a technical problem to be solved. For example, for the random access process, in the case of the number of terminals in the cell constantly changing, and the number of terminals initiating random access constantly changing, since the physical random access channel (PRACH) resource is configured by system information, the update frequency is slow, therefore, maintaining a relatively fixed PRACH resource configuration, the base station needs to constantly detect whether there is a terminal performing a random access process on these resources, therefore, it is not conducive to network energy saving. Therefore, how to configure the PRACH resource to improve the effect of network energy saving is a technical problem to be solved. SUMMARY

[0034] Some concepts and / or terms involved in the resource determination method, apparatus, device and storage medium provided by the embodiments of the present application are explained as follows.

[0035] 1. Synchronization Signal Block (SSB)

[0036] The terminal first detects the NR primary synchronization signal (PSS) detection to obtain a part of the physical cell identifier, that is, N(2)_ID; obtain the orthogonal frequency division multiplexing (OFDM) symbol timing and frequency synchronization; then detect the secondary synchronization signal (SSS) to obtain another part of the physical cell ID, that is, N(1)_ID, to obtain the complete physical cell identifier.

[0037] Then the terminal detects the physical broadcast channel (PBCH) and the demodulation reference signal (DMRS) of the demodulation of the PBCH, obtains the system frame number (SFN) and the SSB index, and further obtains the radio frame (subframe) timing.

[0038] The SSB period in NR is configured in the system information block 1 (SIB1), which can be 5, 10, 20, 40, 80, 160 ms. When initial access is performed, the terminal has not received the SIB1, and the SSB is searched according to the default 20 ms period. The SSB does not appear once every period, but appears several times in a half frame every period. This is designed for beam scanning. Each of the several SSBs corresponds to a beam scanning direction, and finally there is an SSB in each direction. The several SSBs are called an SSB set, and all the SSBs in an SSB set are in the same half frame.

[0039] 2. SSB transmission method in a multi-carrier scenario

[0040] Multi-carrier is a typical operation of 5G NR network, which is used to enhance the network capacity. For Pcell or PScell, the base station must transmit periodic SSB, and the SSB period needs to be less than or equal to 20 ms to be successfully searched by the initial search terminal.

[0041] For intra-band Scell, the base station can transmit SSB, at which time the SSB related parameters are configured when the Scell is added; or the base station can not transmit SSB, at which time the SSB related parameters are not configured when the Scell is added, and the terminal obtains the timing through the SSB on the Pcell.

[0042] For inter-band Scell, the base station must transmit SSB, and the SSB related parameters are configured when the Scell is added.

[0043] 3. Mapping rule of SSB to random access channel occasion (RO) in 5G NR

[0044] The configuration parameters of PRACH resource and SSB-RO are configured in system information block SIB1. In NR, multiple frequency division multiplexing (FDM) PRACH transmission opportunities (also referred to as PRACH Occasions, for short, ROs) can be configured in one time domain location where PRACH is transmitted. At one time, the number of FDM ROs can be {1, 2, 4, 8}, which is determined by the high-layer parameter msg1-FDM.

[0045] The random access preamble (Preamble) can only be transmitted on the time domain resource configured by the parameter PRACHConfigurationIndex and the frequency domain resource configured by the parameter msg1-FDM. The frequency domain resource n RA ∈ {0, 1,..., M-1}, where M is equal to the high-layer parameter msg1-FDM. At the time of initial access, the frequency domain resource n RA The RO resource is numbered in ascending order from the lowest frequency in the initial active uplink bandwidth part, otherwise, the frequency domain resource n RA The RO resource is numbered in ascending order from the lowest frequency in the active uplink bandwidth part. For example, the number of FDM ROs at one time is 8 (msg1-FDM = 8), and the RO resources are numbered in order from low to high in frequency as RO#0 ~ RO#7.

[0046] In NR, there is an association relationship between RO and the actually transmitted SSB. The RO is associated with the SSB in the order of frequency domain (from low frequency to high frequency) and then time domain. One SSB can be associated with multiple consecutive ROs, or one RO can be associated with multiple SSBs (in this case, different SSBs correspond to different Preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0047] All the SSBs associated with one round of ROs form a SSB-RO mapping cycle. One SSB-to-RO association period can contain one or more SSB-RO mapping cycles. One SSB-to-RO association pattern period can contain one or more SSB-to-RO association periods. The SSB-to-RO mapping repeats in the association pattern period, and the maximum association pattern period is 160 ms.

[0048] Generally, the base station can use different beams to transmit different SSBs, where the number of SSBs is configured by the ssb-PositionsInBurst parameter, and the maximum number of SSBs is 64 for FR2 (Frequency Range 2). The terminal selects the RO associated with the SSB with a good signal and the "RO and preamble combination" according to the strength of the received downlink beam / SSB, and transmits Msg1. In this way, the network can determine the SSB selected by the terminal according to the received RO and "RO and preamble combination" of the preamble, and transmit Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0049] For example, the number of FDM ROs at one time is 8, and the actual number of transmitted SSBs is 4, i.e., SSB#0, SSB#1, SSB#2, and SSB#3, and each SSB is associated with 2 ROs. If the terminal determines to transmit PRACH / Msg1 on the RO corresponding to SSB#0, the terminal selects one of RO#0 and RO#1 to transmit PRACH.

[0050] For another example, the number of FDM ROs at one time is 2, and the actual number of transmitted SSBs is 8, i.e., SSB#0, SSB#1, …, and SSB#7, and each 2 SSBs are associated with 1 RO. When multiple SSBs share one RO, the preamble sets associated with the multiple SSBs are different, i.e., the same preamble cannot belong to the preamble sets associated with different SSBs at the same time. For example, RO#0 has 60 preambles, where the preambles with indexes 0-29 are associated with SSB#0, and the preambles with indexes 30-59 are associated with SSB#1.

[0051] Before the terminal sends PRACH, first, according to the received beam (SSB) reference signal received power (Reference Signal Received Power, RSRP), select the SSB whose RSRP is higher than the threshold; if there are multiple SSBs whose RSRP is higher than the threshold, the terminal can select any SSB whose RSRP is higher than the threshold; when there is no SSB whose RSRP is higher than the threshold, the terminal selects one SSB based on implementation.

[0052] Based on network configuration, the terminal obtains the correspondence between SSB and RO. After selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / Preamble / Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of them for PRACH / Preamble / Msg1 transmission.

[0053] For example, assuming that the terminal selects SSB#1, the terminal can select one of RO#2 and RO#3 for PRACH / Msg1 transmission; if the terminal selects SSB#1, the terminal can select the available RO closest to the current time among the ROs (RO#0 or 4) associated with SSB#1 for PRACH / Msg1 transmission. In the selected RO, the terminal selects one preamble from the preamble set associated with the selected SSB for PRACH transmission. For example, an RO is associated with 2 SSBs, then in the available preamble set associated with the SSB in an RO, the preambles will be divided into two subsets, each corresponding to an SSB. The terminal will select a preamble sequence in the preamble subset corresponding to the selected SSB for PRACH / Msg1 transmission.

[0054] 4、R18 network energy saving

[0055] Network energy efficiency is listed as one of the 13 performance requirements of IMT-2020. Most of the power consumption of the NR network comes from the base station, and 90% of the power consumption of the NR base station comes from the Active Antenna Unit (AAU). Due to higher frequency bands, wider bandwidths, more transceivers, and other reasons, the power consumption of a single NR base station is currently 3-4 times higher than that of LTE. In addition, in terms of operating costs, the electricity bill of the base station accounts for nearly 20% of the entire network operating costs. For some operators, the electricity bill is more than half of the total profit. Therefore, network energy saving of NR has become more critical to achieve the great success of 5G. According to the actual load condition, the base station can implement different degrees of energy saving measures, such as shutting down the base station, shutting down the carrier / cell, shutting down the channel, shutting down the SSB / beam, shutting down the antenna / panel, discontinuous transmission and / or discontinuous reception of the cell, Channel State Information (CSI) adaptation, and the like.

[0088] Optionally, in the embodiments of the present application, the default length of the first validity period or the configured validity period is determined by any one of the following: protocol predefinition, and a ratio of the first cycle to the paging cycle. The first cycle includes any one of the following: RO mapping cycle, RO mapping pattern cycle, random access resource configuration cycle (RACH configuration cycle), and SSB cycle.

[0089] It can be understood that if the first validity period is not configured in the first configuration information, the first validity period is NN time units by default. For example, NN is 2 time units pre-defined by the protocol, or NN = ceil(first cycle / paging cycle) + K, ceil is an integer function, and K is an integer or does not exist.

[0090] Optionally, in the embodiments of the present application, the first validity period or the configured validity period is associated with all additional PRACH resources.

[0091] Optionally, in the embodiments of the present application, the first validity period or the configured validity period is associated with a group of the additional PRACH resources. That is, the first validity period or the configured validity period is configured for each group.

[0092] Optionally, in the embodiments of the present application, the first validity period or the configured validity period is associated with one of the additional PRACH resources. That is, the first validity period or the configured validity period is configured for each additional PRACH resource.

[0093] It can be understood that when the network side configures the configured validity period, the additional PRACH resource needs to be reconfigured after the validity time of the configured validity period, that is, after the configuration of the additional PRACH resource is invalid. Optionally, the configured validity period decreases with time after being configured regardless of whether the additional PRACH resource is activated.

[0094] Optionally, in the embodiments of the present application, the time-frequency domain position of the additional PRACH resource can be configured by radio resource control (RRC) configuration information, and the RRC configuration information can also configure the validity period of the activation of the additional PRACH resource. The RRC configuration information can be carried in an existing SIB such as SIB1 or SIB17 or a new SIB.

[0095] Exemplarily, the unit of the validity period of the activation of the additional PRACH resource is 1 paging cycle, and the RRC configuration information configures an effective period from the selection range of the validity period of the activation. For example, the range of the limited period of activation is predefined as a set, and the values in the set are {1, 2, 4, 8…128, 256, 512} and the like. The RRC configuration information configures a specific value of the validity period by using 4 bits. When the RRC configuration information does not have this indication field, the default activation validity period is 2 paging cycles.

[0096] It should be noted that the validity period of the activation in the RRC configuration information described above can be associated with all additional PRACH resources, or can be configured for each group of additional PRACH resources, or can be configured for each resource in the additional PRACH resource.

[0097] Optionally, in the embodiments of the present application, the update information of the validity period of the activation of the additional PRACH resource: one case is that the network side device is not allowed to turn off the validity period by physical layer signaling after the activation of the validity period of the additional PRACH resource, at this time, the physical layer signaling only has the functions of activating the validity period configuration and resetting the validity period. Another case is that the physical layer signaling can activate the validity period of the activation of the additional PRACH resource, and can also suspend the validity period.

[0098] It should be noted that in the embodiments of the present application, the validity period of the additional PRACH resource can be an activated validity period or a deactivated validity period. To prevent repetition, the following description is based on the activated validity period of the additional PRACH resource. It can be understood that the terminal considers the additional PRACH resource outside the validity period to be deactivated. If the validity period is the deactivated validity period of the additional PRACH resource, the terminal considers the additional PRACH resource outside the validity period to be activated.

[0099] In the embodiments of the present application, the update information of the activated validity period of the additional PRACH resource is used to indicate whether the activated validity period of the additional PRACH resource is reset.

[0100] Optionally, in the embodiments of the present application, when the first bit in the first indication information is the first value, the activation or deactivation related information indicates that the activated validity period of the additional PRACH resource associated with the first bit is reset.

[0101] It should be noted that the activation or deactivation related information indicating that the activated validity period of the additional PRACH resource is reset can be understood as the activation or deactivation related information indicating that the activated validity period of the additional PRACH resource is the first validity period, or can be understood as indicating that the validity period in the first configuration information takes effect. It can be understood that according to the activation or deactivation related information, the terminal can determine that the time length of the activated validity period of the additional PRACH resource is updated, that is, the activated validity period is updated to the first validity period. At the same time, the terminal can also determine the activation or deactivation start time and the end time of the associated additional PRACH resource according to the reset information of the validity period. Correspondingly, whether the additional PRACH resource is activated or deactivated can also be determined by the terminal.

[0102] Exemplarily, the first value is 1. It can be understood that the first value can also be 0.

[0103] Optionally, in the embodiments of the present application, when the first bit in the first indication information is the first value, the activation or deactivation related information indicates that the activated validity period of the additional PRACH resource associated with the first bit is decremented.

[0104] It should be noted that the activation or deactivation related information indicating the decrement of the validity period of the activation of the additional PRACH resource (i.e. normal decrement according to time units) can be understood as: the activation or deactivation related information indicates that the assumption of the activation or deactivation of the additional PRACH resource does not change (e.g. the assumption of the time length of the validity period does not change). It can be understood that the terminal can determine that the time length or time range of the validity period of the activation of the additional PRACH resource does not change according to the activation or deactivation related information. At the same time, the terminal can also determine that the start time and end time of the activation or deactivation of the associated additional PRACH resource do not change. Correspondingly, the terminal can also determine which additional PRACH resource is activated or deactivated as the time units decrease.

[0105] Optionally, in the embodiment of the present application, when the first bit in the first indication information is the second value, the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the first bit is suspended.

[0106] It can be understood that when the bit associated with the additional PRACH resource indicates the second value, the terminal considers that the additional PRACH resource is temporarily deactivated, at this time, the validity period is suspended and does not decrease until the first indication information indicates the first value again or the validity period is reconfigured. It can be understood that the terminal can determine that the time length or time range of the validity period of the activation of the additional PRACH resource is updated according to the activation or deactivation related information, because the end time of the activation or deactivation changes. At the same time, the terminal can also determine which additional PRACH resource is activated or deactivated. Another possibility is that when the bit associated with the additional PRACH resource indicates the second value, the terminal considers that the additional PRACH resource is temporarily deactivated, and at this time the validity period decreases normally, i.e. the time length of the validity period decreases with time regardless of whether the associated additional PRACH resource is activated or deactivated. It can be understood that the terminal can determine that the time length or time range of the validity period of the activation of the additional PRACH resource does not change according to the activation or deactivation related information. However, at this time, which additional PRACH resource is activated or deactivated in the validity period range changes, and the terminal can determine this according to the information.

[0107] Optionally, in the embodiment of the present application, in the case that the second bit in the first indication information is the first value and the first bit in the first indication information is the first value, the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the second bit and the first bit is decremented. It can be understood that according to the activation or deactivation related information, the terminal can determine that the time length or time range of the validity period of the activation of the additional PRACH resource has not changed. At the same time, the terminal can also determine that the start time and the end time of the activation or deactivation of the additional PRACH resource have not changed. Correspondingly, the terminal can also determine which additional PRACH resource is activated or deactivated as the time unit is decremented.

[0108] It can be understood that the additional PRACH resource is associated with two bits, one bit indicates whether the validity period is reset, and the other bit indicates whether the validity period is decremented. Compared with the indication mode of one bit indicating whether the validity period is reset, it can avoid that the terminal cannot determine whether the additional PRACH resource is activated or not when no indication information is received.

[0109] Optionally, in the embodiment of the present application, in the case that the second bit in the first indication information is the first value and the first bit in the first indication information is the second value, the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the second bit and the first bit is suspended. It can be understood that according to the activation or deactivation related information, the terminal can determine that the time length or time range of the validity period of the activation of the additional PRACH resource has been updated, because the end time of the activation or deactivation has changed. Correspondingly, the terminal also needs to re-determine whether the additional PRACH resource is activated or not.

[0110] It should be noted that whether the validity period is decremented can also mean whether the validity period is suspended, that is, the validity period is not decremented is equivalent to suspending the validity period, and the validity period is decremented is equivalent to not suspending the validity period. It can be understood that the validity period is decremented, that is, the associated additional PRACH resource is activated, and the validity period is suspended, that is, the associated additional PRACH resource is deactivated.

[0111] It should be noted that when there are two associated bits, the first bit is used to determine whether the validity period of the activation of the additional PRACH resource associated with the bit is decremented or suspended, and the second bit is used to determine whether the validity period of the activation of the additional PRACH resource associated with the bit is reset.

[0112] Alternatively, the first bit is used to determine whether the additional PRACH resource associated with the bit is activated, and the second bit is used to determine whether the validity period of the activation of the additional PRACH resource associated with the bit is reset.

[0113] Or, the first bit is used to determine whether the additional PRACH resource associated with the bit is activated or not; and the second bit is used to determine whether the validity period of the activation of the additional PRACH resource associated with the bit is decremented or suspended.

[0114] Optionally, in the embodiments of the present application, the first bit can be the first bit, and the second bit can be the next bit of the first bit. It can be understood that the first bit can also be the second bit associated with the additional PRACH resource, and the second bit is the previous bit of the first bit.

[0115] Exemplarily, the second value is 0. It can be understood that the second value can also be 0.

[0116] Optionally, in the embodiments of the present application, in the case that the first bit in the first indication information is the second value or the first indication information is not received, the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the first bit is decremented.

[0117] It should be noted that the additional PRACH resource associated with each bit is configured by the network side device, that is, the additional PRACH resource associated with each indication bit is determined, and is irrelevant to whether the first indication information is received or not. Therefore, even if the first indication information is not received, the activation or deactivation related information can indicate that the validity period of the activation of the additional PRACH resource associated with the first bit is decremented, that is, the terminal considers that the validity period of the activation of the additional PRACH resource associated with the first bit is decremented.

[0118] Optionally, in the embodiments of the present application, in the case that the first bit in the first indication information is the second value, the activation or deactivation related information indicates that the additional PRACH resource associated with the first bit is deactivated until the indication that the first bit is the first value is received. It can be understood that at this time, as long as the indication that the first bit is the second value is received, the associated PRACH resource is considered to be deactivated.

[0119] Optionally, in the embodiments of the present application, in the case that the first bit in the first indication information is the second value, the activation or deactivation related information indicates that the validity period of the activation of the additional PRACH resource associated with the first bit is not decremented until the indication that the first bit is the first value is received. It can be understood that when the first bit is the second value, the validity period is suspended until the first bit is the first value.

[0120] Optionally, in the embodiments of the present application, in the case that the first indication information is not received, whether the additional PRACH resource is deactivated or whether the validity period of the activated additional PRACH resource is decremented is determined according to the last received indication information. It can be understood that when the terminal does not receive the first indication information due to various reasons, the terminal determines the activation or deactivation related information of the additional PRACH resource according to the previously received indication information. For example, when the last received indication information indicates that some additional PRACH resource is activated, it is still considered to be activated; or when the last received indication information indicates that the validity period is normally decremented, it is also considered that the validity period is normally decremented.

[0121] Optionally, in the embodiments of the present application, in the case that the first bit in the first indication information is the second value and the indication information in which the first bit is the first value has not been received, the activation or deactivation related information indicates that the additional PRACH resource in the first time window is activated, and the first time window is the current period in the validity period or at least one period after the current period in the validity period.

[0122] It can be understood that the terminal can not receive the signaling related to the validity period setting or updating, and when it can only be determined that the current is in the validity period, how to determine whether the subsequent additional PRACH resource is activated needs to be determined. Since it can be determined that the current is in the validity period, the terminal considers that the additional PRACH resource in the first time window is activated according to the above information.

[0123] It should be noted that the network side device periodically sends the first indication information, and in the case that the terminal receives the first indication information in which the first bit is the second value and has not received the first indication information in which the first bit is the first value, the activation or deactivation related information indicates that the additional PRACH resource in the first time window is activated. It can be understood that when the first bit is the second value, it indicates that the validity period is normally decremented, so even if the first indication information indicating the validity period is not received, the terminal can at least determine that the additional PRACH resource in the current period of the validity period is activated.

[0124] Optionally, in the embodiments of the present application, in the case that the first indication information in which the first bit is the first value is received, the activation or deactivation related information indicates that the additional PRACH resource in the first time window is activated.

[0125] Optionally, in the embodiments of the present application, when the first indication information with the first bit being the second value is received, the terminal considers that the additional PRACH resource in the first time window is activated, in the case that the first indication information with the first bit being the first value is received in the second time window. It can be understood that the above case is considered to be true only in the case that the first indication information with the first bit being the first value is received in the second time window, otherwise, the additional PRACH resource in the first time window is not considered to be activated.

[0126] Optionally, in the embodiments of the present application, the end position of the second time window is the time when the first indication information with the first bit being the second value is received, or before the time. The second time window can be at least one time unit, which can include any of the following: millisecond, time slot, symbol, subframe, frame, DRX cycle, paging cycle, random access resource configuration cycle, SSB-RO mapping cycle, SSB-RO mapping pattern cycle.

[0127] Optionally, in the embodiments of the present application, the additional PRACH resource is not available in the case that the first indication information indicating the activation of the additional PRACH resource is not received. It can be understood that after the network side configures the validity period information of the additional PRACH resource, the first indication information is required for indication, and the configuration is considered to be effective.

[0128] Optionally, in the embodiments of the present application, the activation or deactivation start time of the additional PRACH resource is any of the following:

[0129] The first configuration cycle, or the first SSB-RO mapping pattern cycle, or the first SSB-RO mapping cycle of the additional PRACH resource in the first validity period;

[0130] The first additional PRACH resource in the first validity period;

[0131] The next paging cycle or the next DRX cycle;

[0132] The current paging cycle or the current DRX cycle;

[0133] The time when the first indication information is received;

[0134] The first additional PRACH resource position after the time when the first indication information is received;

[0135] The time after at least one time unit after the first indication information is received;

[0136] The first additional PRACH resource position after at least one time unit after the first indication information is received.

[0137] Optionally, in embodiments of the present application, the at least one time unit includes at least one of the processing time indicated by the first indication and the Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) feedback time.

[0138] Optionally, in embodiments of the present application, the association between the additional PRACH resource and the first indication information includes that the identifier of each additional PRACH resource is associated with one bit in the first indication information respectively.

[0139] It can be understood that each bit in the at least one bit in the first indication information is associated with one additional PRACH resource respectively.

[0140] Optionally, in embodiments of the present application, the association between the identifier of each additional PRACH resource and the bit in the first indication information includes that the additional PRACH resource with the identifier i is associated with the (i+1)th bit in the first indication information, and i is a positive integer.

[0141] It can be understood that each additional PRACH resource is configured with one identifier, and the identifier i of the additional PRACH resource is associated with the (i+1)th bit in the first indication information. That is, the network side device assigns an id to each additional PRACH resource when configuring the additional PRACH resource, so that the first indication information only needs to use one bitmap to indicate the activation or deactivation related information of which part of the additional PRACH resource if the additional PRACH resource is activated or deactivated in groups. It can be understood that different additional PRACH resources can be configured with the same identifier, that is, the additional PRACH resources are grouped. In particular, if the additional PRACH resources are not grouped, the first indication information only needs one bit to indicate the activation or deactivation related information of all additional PRACH resources.

[0142] Optionally, in embodiments of the present application, the second configuration information includes at least one of the following:

[0143] SSB index;

[0144] Configuration index of the additional PRACH;

[0145] Third information corresponding to the configuration information of the first PRACH, the third information including at least one of the following: scaling factor, offset value;

[0146] Relationship between the additional PRACH resource and the first PRACH resource;

[0147] PRACH resource parameter;

[0148] power parameters;

[0149] competition and measurement related parameters.

[0150] It should be noted that the first PRACH can be a legacy PRACH, or a PRACH configured or existed by the network side device, or a PRACH corresponding to an existing standard version.

[0151] Optionally, in the embodiments of the present application, the SSB index is an SSB index having a quasi co-location (QCL) relationship with the additional PRACH resource.

[0152] Optionally, in the embodiments of the present application, the configuration index of the additional PRACH is used to determine the additional PRACH resource from a first table, wherein the first table includes at least one PRACH configuration index and corresponding preamble format, PRACH resource configuration period, and radio frame position, subframe position, starting symbol of the PRACH resource.

[0153] It can be understood that the terminal determines the PRACH resource corresponding to the configuration index of the additional PRACH from the first table according to the configuration index of the additional PRACH configured by the network side device.

[0154] PRACH configuration index) from the first table as the additional PRACH resource.

[0155] Exemplarily, the first table is shown in Table 1, the first PRACH is indicated by the PRACH configuration index of row 5, and the additional PRACH is indicated by the configuration index of the additional PRACH of row 17, so that the time domain resource of the first PRACH is subframe 4 of even SFN, and the time domain resource of the additional PRACH is subframe 4, 9 in each SFN.

[0156] Table 1

[0157] Optionally, in the embodiments of the present application, the configuration information of the first PRACH includes at least one of the following: subframe of system frame number (SFN), starting symbol of SFN, number of PRACH slots of SFN, number of PRACH occasions of SFN, and PRACH length of SFN.

[0158] Exemplarily, the additional PRACH resource is determined according to third information corresponding to configuration information of the first PRACH. In the above Table 1, the configuration n f , x, y, subframe number, scaling factor (or offset value offset) of starting symbol. n f is the radio frame position where the RO is located, x is the configuration period of the RO, y is the intermediate value used to determine n f .

[0159] For example, the first PRACH is indicated by PRACH configuration index row 5, so that the time domain resource of the first PRACH is subframe 4 of even SFN (SFN 0, 2, 4…), the network side device configures parameter SFN-offset as m, then the additional PRACH resource is subframe 4 of SFN (m, 2+m, 4+m…), if the network side device configures parameter subframe-offset or slot-offset as n, then the additional PRACH resource is subframe (4+n) of SFN (SFN 0, 2, 4…), if the network side device configures SFN-offset as m and subframe-offset or slot-offset as n at the same time, then the additional PRACH resource is subframe (4+n) of SFN (n, 2+n, 4+n…).

[0160] For example, xn is configured as the scaling factor of x, then x' of the additional PRACH is x*xn. It can be understood that the configuration period of the additional PRACH resource is scaled according to the configuration period of the first PRACH resource.

[0161] Optionally, in the embodiments of the present application, the relationship between the above-mentioned additional PRACH resource and the first PRACH resource (legacy PRACH resource) includes any one of the following:

[0162] The additional PRACH resource does not overlap with the first PRACH resource;

[0163] The additional PRACH resource overlaps with the first PRACH resource;

[0164] The resource position of the additional PRACH resource has interval with the first PRACH resource;

[0165] The first PRACH resource is masked by the network, and is used as the additional PRACH resource.

[0166] Optionally, in the embodiments of the present application, the additional PRACH resource overlaps with the first PRACH resource. The overlapping resource is used for mapping SSB and RO of the first PRACH resource, and is not used as the additional PRACH resource; or the overlapping resource can be used for mapping SSB and RO, and the RO of the additional PRACH resource is invalid after mapping; or the RO of the additional PRACH resource and the first PRACH resource cannot be partially overlapped, and can be completely overlapped; or in the case of mapping multiple ROs to one SSB, the additional PRACH resource and the first PRACH resource have no overlapping resource which is preferentially masked by the network.

[0167] Optionally, in the embodiments of the present application, the interval is related to at least one of a sub-carrier spacing (SCS) and a sequence length of the PRACH.

[0168] Optionally, in the embodiments of the present application, the first PRACH resource masked by the network is used as the additional PRACH resource. The RO of the first PRACH resource masked by the network cannot be unmasked; or in the case that the RO of the first PRACH resource masked by the network is unmasked, the RO is no longer used as the additional PRACH resource.

[0169] Optionally, in the embodiments of the present application, in the case that the RO is no longer used as the additional PRACH resource, the additional PRACH resource is remapped with the SSB, or the mapping relationship between the additional PRACH resource and the SSB remains unchanged and the RO is unavailable.

[0170] It can be understood that the relationship between the additional PRACH resource and the first PRACH resource can include at least one of the following cases 1 to case 4:

[0171] Case 1: The network side device configures the additional PRACH resource to avoid overlapping with the first PRACH (or at least the PRACH resource without mask), or the terminal does not expect the network side device to configure the first PRACH and the additional PRACH to overlap. The overlapping cases include at least one of the following: time domain partial or complete overlap, frequency domain partial or complete overlap.

[0172] Case 2: The network side device can configure the additional PRACH resource to overlap with the first PRACH (or at least the PRACH resource without mask), and the overlapping cases include at least one of the following: time domain partial or complete overlap, frequency domain partial or complete overlap. For the overlapping resource, at least one of the following modes (1) to (4) can be used for processing:

[0173] The overlapped resource can only be used for mapping of the first PRACH to the SSB-RO, and cannot be used as an additional PRACH, or in other words, when overlap occurs, the additional RO is invalid, and the additional RO is not mapped in the SSB-RO mapping process of the additional RO, or in other words, when overlap occurs, the overlapped RO is not considered to belong to the additional PRACH resource.

[0174] In other words, the validity of the additional RO is determined by the legacy RO or the legacy RO without the mask.

[0175] The overlapped resource can be used for mapping of the SSB-RO, but after mapping, the additional RO is considered to be invalid.

[0176] The RO cannot be partially overlapped, but can be completely overlapped, or in other words, the RO can be shared, and it can be understood that the terminal does not expect the RO to be configured to be partially overlapped, or when partially overlapped, the above-mentioned manner (1) or manner (2) is used, and when completely overlapped, the legacy RO and the additional RO can be distinguished by different preambles.

[0177] The network side device configures the PRACH mask to make the mapped part of the RO used for transmission of the PRACH, and the network side device preferentially masks the resource without overlap.

[0178] Case 3: The network side device configures at least one of the time domain and frequency domain positions of the additional RO, and the first PRACH (or at least the PRACH resource without the mask) satisfies a certain interval. Optionally, the interval is related to at least one of the SCS and the sequence length of the PRACH.

[0179] For example, the time domain of the configured legacy RO is in subframe 4, and the time domain of the additional RO is in a subframe that is at least 2 subframes apart from subframe 4.

[0180] Optionally, when the configured additional RO and the first PRACH (or at least the PRACH resource without the mask) do not satisfy the above-mentioned interval, the above-mentioned manner (1) or manner (2) is used.

[0181] Case 4: The legacy RO masked by the network can be configured or indicated by the network side as an additional PRACH resource.

[0182] Optionally, if configured as an additional PRACH resource, these ROs cannot be unmasked.

[0183] Optionally, if the legacy ROs that are masked are unmasked, these ROs are no longer additional PRACH resources.

[0184] Optionally, the mapping between SSB and additional PRACH resources is re-performed.

[0185] Optionally, the mapping relationship is unchanged, but these additional PRACH resources are considered unavailable.

[0186] Optionally, in the embodiments of the present application, the PRACH resource parameters (in order to distinguish the first PRACH and the additional PRACH resource) include at least one of the following: PRACH configuration index, starting position of RO frequency domain, number of RO frequency domain multiplexing, number of SSB corresponding to one RO, subset of SSB for additional PRACH, subset of preamble for additional PRACH, PRACH mask indication.

[0187] Optionally, in the embodiments of the present application, the power parameters include at least one of the following: power ramping, initial preamble power (preambleReceivedTargetPower). Since different configurations of additional PRACHs may result in different target powers, different power parameters need to be configured to keep the terminal transmission power consistent.

[0188] Optionally, in the embodiments of the present application, the parameters related to contention and measurement include at least one of the following: size of random access response (RAR) window, threshold of measuring SSB signal quality (such as RSRP), contention resolution timer.

[0189] Optionally, in the embodiments of the present application, in the case where the valid period of activation of the additional PRACH resource overlaps with the configuration period of the additional PRACH resource, any of the following is included:

[0190] The additional PRACH resource in the overlapping time is activated;

[0191] The additional PRACH resource in the configuration period of the additional PRACH resource where the overlapping time is located is activated;

[0192] When the configuration period of the additional PRACH resource is located within the valid period of activation of the additional PRACH resource, the additional PRACH resource is activated.

[0193] In the embodiments of the present application, since the activation indication of the additional PRACH resource (i.e., the first indication information described above) is carried in the paging-related DCI (for example, DCI format 1-0 or DCI format 2-7), and the transmission frequency of these DCIs is related to the paging cycle, the validity period of the activation of the additional PRACH resource is also in units of paging cycles. However, the configuration of the additional PRACH resource is related to the random access resource configuration period (RACH configuration period), so when the paging cycle is not the same as the random access resource configuration period, it is difficult for the validity period of the activation to completely align with the random access resource configuration period. Therefore, when the validity period of the activation decreases to the last paging cycle, the range of the validity period of the activation may only contain part of the additional PRACH resource in one configuration period. At this time, it needs to be determined whether the additional PRACH resource in this configuration period is activated. As described above, it can be considered that only the additional PRACH resource in the range of the validity period of the activation is activated, even if part of the additional PRACH resource outside the validity period belongs to the same configuration period as part of the additional PRACH resource in the range of the validity period. Another possibility is that as long as there is an overlapping part, it is considered that all the additional PRACH resources in the configuration period are activated. Still another possibility is that only when all the additional PRACH resources in the configuration period are located in the range of the validity period of the activation, these additional PRACH resources are considered to be activated.

[0194] In the embodiments of the present application, for the first validity period or the configuration validity period of the additional PRACH resource described above: the length of time for activating or deactivating the additional PRACH resource can be controlled, and when the terminal does not receive the related indication information of the activation or deactivation, it can still be determined whether the additional PRACH resource is activated.
