Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a resource determination method, apparatus, device and storage medium. Background Technology

[0002] Network energy efficiency is crucial for environmental sustainability, reducing environmental impact, and saving operating costs. As 5G becomes more widespread across industries and regions, and more advanced services and applications require extremely high data rates, networks are becoming denser, using more antennas, greater bandwidth, and more frequency bands. The environmental impact of 5G needs to be kept under control, necessitating the development of new solutions to improve network energy efficiency.

[0003] Currently, the power consumption of wireless access can be divided into two parts: the dynamic part is consumed only when data is being transmitted or received, while the static part is consumed continuously to maintain the operation of the wireless access device, even when data transmission or reception is not in progress. Therefore, minimizing the power consumption of the static part is a technical problem that needs to be solved. For example, in the random access process, with the number of terminals in a cell constantly changing, and the number of terminals initiating random access also constantly changing, the Physical Random Access Channel (PRACH) resources are configured through system information and updated slowly. Therefore, maintaining a relatively fixed PRACH resource configuration requires the base station to constantly check these resources to see if any terminals are performing random access procedures, which is detrimental to network energy saving. Thus, how to configure PRACH resources to improve network energy saving is a technical problem that needs to be solved. Summary of the Invention

[0032] The following explains some concepts and / or terms involved in the resource determination method, apparatus, device, and storage medium provided in the embodiments of this application.

[0033] 1. Synchronization Signal Block (SSB)

[0034] The terminal first detects the NR primary synchronization signal (PSS) to obtain a part of the physical cell identifier, namely N(2)_ID; obtains the orthogonal frequency division multiplexing (OFDM) symbol timing and frequency synchronization; then detects the secondary synchronization signal (SSS) to obtain the other part of the physical cell ID, namely N(1)_ID, and obtains the complete physical cell identifier.

[0035] Then the terminal detects the Physical Broadcast Channel (PBCH) and the Demodulation Reference Signal (DMRS) of the PBCH to obtain the System Frame Number (SFN) and SSB index, and further obtains the timing of the radio frame (subframe).

[0036] In NR, the SSB period is configured in System Information Block 1 (SIB1), and can be 5, 10, 20, 40, 80, or 160 ms. During initial access, the terminal has not yet received SIB1, so it will search for SSBs according to the default 20 ms period. SSBs do not appear once at regular intervals, but rather several times within a certain half-frame at regular intervals. This is designed for beam scanning. Each of these SSBs corresponds to a beam scanning direction, and ultimately there will be an SSB in each direction. These SSBs are called an SSB set, and all SSBs in an SSB set must be within the same half-frame.

[0037] 2. SSB transmission method in multi-carrier scenarios

[0038] Multicarrier operation is a typical feature of 5G NR networks, used to enhance network capacity. For Pcells or PScells, the base station must send periodic SSBs, and the SSB period must be less than or equal to 20ms for a terminal to be successfully searched initially.

[0039] For intra-band Scells, the base station can send SSBs, in which case the SSB-related parameters are configured when adding the Scell; alternatively, it can not send SSBs, in which case the SSB-related parameters are not configured when adding the Scell, and the terminal obtains the timing through the SSB on the Pcell.

[0040] For inter-band Scells, the base station must send an SSB and configure the SSB-related parameters when adding the Scell.

[0041] 3. Mapping rules from SSB to Random Access Channel Occasion (RO) in 5G NR

[0042] The configuration parameters for PRACH resources and SSB-ROs are configured in System Information Block SIB1. In NR, a cell can configure multiple Frequency Division Multiplexing (FDM) PRACH transmission occasions (ROs) at a single time-domain location for PRACH transmission. At any given time, the number of ROs eligible for FDM can be {1, 2, 4, 8}, determined by the higher-layer parameter msg1-FDM.

[0043] The random access preamble can only be transmitted on the time-domain resources configured by the parameter PRACHConfigurationIndex and the frequency-domain resources configured by the parameter msg1-FDM. PRACH frequency-domain resources n RA ∈{0,1,...,M-1}, where M equals the higher-layer parameter msg1-FDM. At initial access, the PRACH frequency domain resource n RA Starting with the lowest frequency RO resource within the initial active uplink bandwidth part, number them in ascending order; otherwise, use the PRACH frequency domain resource n. RA The RO resources within the active uplink bandwidth part are numbered in ascending order, starting with the lowest frequency RO resource. For example, if the number of ROs in the FDM at a given time is 8 (msg1-FDM=8), the RO resources are numbered sequentially from low to high frequency as RO#0 to RO#7.

[0044] In NR, there is an association between ROs and the actual transmitted SSBs. ROs are associated with SSBs in the order of frequency domain (from low frequency to high frequency) and then time domain. An SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with one RO (in which case, different SSBs correspond to different preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0045] After all SSBs have completed one round of association with RO, they constitute an SSB-RO mapping cycle. An SSB-RO association period may contain one or more SSB-RO mapping cycles. An SSB-RO association pattern period may contain one or more SSB-RO association periods. The SSB-RO mapping repeats with the association pattern period as the cycle, and the maximum association pattern period is 160ms.

[0046] Typically, base stations can use different beams to transmit different SSBs. The number of SSBs is configured via the `ssb-PositionsInBurst` parameter; for FR2 (Frequency Range 2), the maximum number of SSBs is 64. The terminal selects the RO / "RO and preamble combination" associated with the SSB with the best signal strength based on the received downlink beam / SSB strength, and then transmits `Msg1`. In this way, the network can determine the SSB selected by the terminal based on the received preamble's RO / "RO and preamble combination". Then, it transmits `Msg2` on the corresponding downlink beam of the SSB to ensure the quality of downlink signal reception.

[0047] For example, if the number of ROs in an FDM at a given time is 8, and the number of SSBs actually transmitted is 4, namely SSB#0, SSB#1, SSB#2, and SSB#3, with each SSB associated with 2 ROs. If the terminal determines to send PRACH / Msg1 on the RO corresponding to SSB#0, then the terminal selects one RO from RO#0 and RO#1 to send the PRACH.

[0048] For example, at a given moment, the number of ROs in an FDM is 2, and the actual number of SSBs transmitted is 8, namely SSB#0, SSB#1, ..., SSB#7, with each pair of SSBs associated with one RO. When multiple SSBs share a single RO, the preamble sets associated with these multiple SSBs are different; that is, the same preamble cannot belong to different preamble sets associated with different SSBs simultaneously. Taking RO#0 as an example, RO#0 has 60 preambles, of which preambles with indices 0 to 29 are associated with SSB#0, and preambles with indices 30 to 59 are associated with SSB#1.

[0049] Before sending PRACH, the terminal first selects an SSB with an RSRP higher than a threshold based on the Reference Signal Receiving Power (RSRP) of the received beam (SSB). If multiple SSBs have RSRPs higher than the threshold, the terminal can select any SSB with an RSRP higher than the threshold. If there is no SSB with an RSRP higher than the threshold, the terminal selects an SSB based on implementation.

[0050] Based on network configuration, the terminal obtains the mapping between SSBs and ROs. After selecting an 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 choose one of the ROs to send PRACH / Preamble / Msg1.

[0051] For example, assuming the terminal selects SSB#1, it can choose between RO#2 and RO#3 for PRACH / Msg1 transmission. If the terminal selects SSB#1, it can choose the nearest available RO (RO#0 or 4) associated with SSB#1 for PRACH / Msg1 transmission. Within the selected RO, the terminal selects a preamble from the preamble set associated with the selected SSB for PRACH transmission. For example, if an RO is associated with two SSBs, the available preamble set associated with each SSB in that RO will be divided into two subsets, each corresponding to one SSB. The terminal will select a preamble sequence from the subset corresponding to the selected SSB for PRACH / Msg1 transmission.

[0052] 4. Energy saving in R18 networks

[0053] Network energy efficiency is listed as one of the 13 performance requirements of IMT-2020. The majority of power consumption in NR networks comes from base stations, with 90% of the power consumption of NR base stations originating from the Active Antenna Unit (AAU). Due to higher frequency bands, wider bandwidth, and more transceivers, the power consumption of a single NR base station is currently 3-4 times higher than that of LTE. Furthermore, in terms of operating costs, base station electricity costs account for nearly 20% of the total network operating costs. For some operators, electricity costs account for more than half of their total profits. Therefore, energy saving in NR networks is becoming increasingly critical for the great success of 5G. Depending on the actual load, base stations can implement different levels of energy-saving measures, such as shutting down the base station, shutting down carriers / cells, shutting down channels, shutting down SSBs / beams, shutting down antennas / panels, discontinuous cell transmission and / or discontinuous cell reception, and adaptive Channel State Information (CSI).

[0054] The resource determination method, apparatus, device, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0055] This application provides a resource determination method. Figure 2 A flowchart of a resource determination method provided in an embodiment of this application is shown. For example... Figure 2 As shown, the resource determination method provided in this application embodiment may include the following step 201.

[0056] Step 201: The terminal determines the second information based on the first information.

[0057] In this embodiment of the application, the first information includes at least one of the following: first configuration information and first indication information, wherein the first indication information is used to indicate information related to the activation or deactivation of additional PRACH resources. The second information includes at least one of the following: additional PRACH resources and information related to the activation or deactivation of additional PRACH resources.

[0058] It should be noted that the additional PRACH resources described in the embodiments of this application can be understood as: PRACH resources configured separately by the network-side device in addition to the traditional PRACH resources. This type of PRACH resource is not visible to traditional terminals.

[0059] In this embodiment of the application, the first configuration information mentioned above includes at least one of the following:

[0060] The first validity period is the validity period for activating or deactivating the additional PRACH resource;

[0061] The validity period of the additional PRACH resource configuration;

[0062] The association between additional PRACH resources and the first instruction information;

[0063] Additional PRACH resource group identifier;

[0064] The second configuration information is used to determine the additional PRACH resources.

[0065] Optionally, in this embodiment of the application, the first information mentioned above may be predefined by the protocol, configured by the network-side device, or pre-configured.

[0066] Optionally, in this embodiment of the application, the first information mentioned above includes first configuration information, and the second information mentioned above includes additional PRACH resources.

[0067] Optionally, in this embodiment of the application, the first information includes first configuration information, the first configuration information includes second configuration information, the second information includes additional PRACH resources, and the second configuration information is used to determine at least one of the resource location, mapping rules and transmission parameters of the additional PRACH resources.

[0068] Optionally, in this embodiment of the application, the first information includes first configuration information, which includes at least one of the first validity period, configuration validity period, association relationship and group identifier. The second information includes information related to the activation or deactivation of the additional PRACH resource. That is, the first configuration information is used to determine the information related to the activation or deactivation of the additional PRACH resource.

[0069] Optionally, in this embodiment of the application, the first information mentioned above includes first instruction information, and the second information mentioned above includes information related to the activation or deactivation of additional PRACH resources.

[0070] Optionally, in this embodiment of the application, the aforementioned first configuration information is carried on an SIB, which is either an existing SIB with added relevant indication fields or a newly added SIB. For example, the existing SIB is SIB1.

[0071] Optionally, in this embodiment, when the SIB scheduling information indicates a change in the SIB, the aforementioned first configuration information is invalid until the first indication information is received. It can be understood that after the first configuration information and the first indication information activate the additional PRACH resource, if the terminal receives network broadcast information carrying the first configuration information, such as modification information for the SIB, the terminal considers the first configuration invalid, i.e., the corresponding additional PRACH resource is deactivated, until the associated first indication information is received again. Furthermore, the modification information can be a modification of any indication field in this broadcast information, or it can focus only on whether the first configuration information has been modified.

[0072] Optionally, in this embodiment, the first indication information is carried on downlink control information (DCI), which is either an existing DCI format or a newly added DCI format. For example, an existing DCI format is DCI format 1-0 or DCI format 2-7.

[0073] Optionally, in the embodiments of this application, the aforementioned existing format DCI is an existing format DCI with added relevant indicator fields, or a DCI after reinterpreting the existing indicator fields in the existing format DCI.

[0074] Optionally, in this embodiment of the application, the existing format DCI carrying the first indication information is scrambled by an existing Radio Network Temporary Identifier (RNTI) or a newly defined RNTI.

[0075] Optionally, in this embodiment, different DCI formats are used to indicate terminals in different states. The DCI is a first DCI format, where the first indication information indicates a terminal in a connected state; or, the DCI is a second DCI format, where the first indication information indicates a terminal in an idle or inactive state. For example, DCI format 1-0 carrying the first indication information is used to indicate second information of a terminal in a connected state, and DCI formats 2-7 carrying the first indication information are used to indicate second information of a terminal in an idle or inactive state.

[0076] Optionally, in the embodiments of this application, the above-mentioned additional PRACH resources include at least one of the following: additional RACH Occasion, additional RACH Occasion group, preamble, and preamble group.

[0077] It should be noted that the validity period for activation or deactivation described in this application embodiment can also be referred to as the activation or deactivation time window. That is, the aforementioned additional PRACH resource is either the time window for activating the additional PRACH resource or the time window for deactivating the additional PRACH resource.

[0078] Optionally, in this embodiment of the application, the activation or deactivation related information mentioned above includes at least one of the following:

[0079] First validity period;

[0080] The attached PRACH resource is either active or deactivated;

[0081] Updated information on the validity period of the PRACH resource activation;

[0082] The start time for the activation or deactivation of the attached PRACH resource; it can be understood that the terminal can determine from the start time whether the attached PRACH resource is activated or deactivated based on the start time information. This start time can also be understood as the start time of the first validity period.

[0083] The activation or deactivation end time of the attached PRACH resource; it can be understood that the terminal can determine from the moment when the attached PRACH resource is no longer activated or deactivated. This end time can also be understood as the end time of the first validity period.

[0084] Optionally, in this embodiment, the time unit of the first validity period or configuration validity period includes at least one of the following: N paging cycles, N discontinuous reception (DRX) cycles, N RO mapping cycles, N RO mapping pattern cycles, N random access resource configuration cycles, N SSB cycles, N frames, N milliseconds (ms), N slots, and N symbols. N is a positive integer.

[0085] For example, the first validity period mentioned above includes {1,2,4,8,16,…256,512} paging cycles.

[0086] Optionally, in this embodiment, the default length of the first validity period or configuration validity period is determined by any one of the following: protocol predefinition, the ratio of the first period to the paging period. The first period includes any one of the following: RO mapping period, RO mapping pattern period, random access resource configuration period (RACH configuration period), and SSB period.

[0087] It is understandable that if the first validity period is not configured in the first configuration information above, the first validity period defaults to NN time units. For example, NN is 2 time units predefined by the protocol, or NN = ceil(first cycle / paging cycle) + K, where ceil is the floor function, K is an integer, or K does not exist.

[0088] Optionally, in this embodiment of the application, the first validity period or configuration validity period mentioned above is associated with all additional PRACH resources.

[0089] Optionally, in this embodiment, the first validity period or configuration validity period is associated with one packet in the additional PRACH resources. That is, the first validity period or configuration validity period is configured for each packet.

[0090] Optionally, in this embodiment, the first validity period or configuration validity period is associated with one of the additional PRACH resources. That is, the first validity period or configuration validity period is configured for each additional PRACH resource.

[0091] It is understandable that when the network side is configured with a configuration validity period, the additional PRACH resource needs to be reconfigured after the validity period expires, i.e., after the configuration of the additional PRACH resource becomes invalid. Optionally, the configuration validity period decreases over time after configuration, regardless of whether the additional PRACH resource is active.

[0092] Optionally, in this embodiment, the time-frequency domain location of the additional PRACH resource can be configured by Radio Resource Control (RRC) configuration information, and the RRC configuration information can also configure the activation validity period of the additional PRACH resource. The RRC configuration information can be carried in an existing SIB such as SIB1 or SIB17, or in a new SIB.

[0093] For example, the validity period of the activation of the additional PRACH resource is measured in units of one paging cycle. The RRC configuration information configures a validity period from the selected range of activation validity periods. For instance, the range of activation validity periods is predefined as a set containing values ​​such as {1, 2, 4, 8…128, 256, 512}. The RRC configuration information uses 4 bits to configure a specific validity period value. When the RRC configuration information does not have this indication field, the default activation validity period is two paging cycles.

[0094] It should be noted that the activation validity period in the above RRC configuration information can be associated with all additional PRACH resources, or it can be configured for a group of each additional PRACH resource, or it can be configured for a single resource within each additional PRACH resource.

[0095] Optionally, in this embodiment, regarding the update information for the validity period of the activated additional PRACH resource: One scenario is that after the validity period of the additional PRACH resource is activated, the network-side device is not allowed to disable the validity period via physical layer signaling. In this case, the physical layer signaling only serves to activate the validity period configuration and reset the validity period. Another scenario is that the physical layer signaling can activate the validity period of the activated additional PRACH resource, or it can suspend the validity period.

[0096] It should be noted that, in this embodiment, the validity period of the attached PRACH resource can be either the activation validity period or the deactivation validity period. To avoid redundancy, the following description will use the validity period as the activation validity period of the attached PRACH resource. It can be understood that the terminal considers the attached PRACH resource outside its validity period to be deactivated. If the validity period is the deactivation validity period of the attached PRACH resource, then the terminal considers the attached PRACH resource outside its validity period to be active.

[0097] In this embodiment, the update information of the activation validity period of the additional PRACH resource is used to indicate whether the activation validity period of the additional PRACH resource should be reset.

[0098] Optionally, in this embodiment of the application, when the first bit in the first indication information is a first value, the activation or deactivation related information indicates the expiration date reset of the activation of the additional PRACH resource associated with the first bit.

[0099] It should be noted that the activation or deactivation information indicating a reset of the validity period of the attached PRACH resource activation can be understood as: the activation or deactivation information indicates that the validity period of the attached PRACH resource activation is the first validity period, or it can be understood as indicating that the validity period in the first configuration information is effective. It can be understood that, based on this activation or deactivation information, the terminal can determine that the validity period of the attached PRACH resource activation has been updated, i.e., updated to the first validity period. Simultaneously, the terminal can also determine the start and end times of the associated attached PRACH resource activation or deactivation based on this validity period reset information. Correspondingly, the terminal can also determine which attached PRACH resources are activated or deactivated.

[0100] For example, the first value mentioned above is 1. It can be understood that the first value mentioned above can also be 0.

[0101] Optionally, in this embodiment of the application, when the first bit in the first indication information is a first 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 decreases.

[0102] It should be noted that the activation or deactivation information indicating a decrease in the validity period of the attached PRACH resource activation (i.e., a normal decrease according to time units) can be understood as: the activation or deactivation information indicates that the assumptions regarding the activation or deactivation of the attached PRACH resource remain unchanged (e.g., the assumption that the validity period of activation remains unchanged). It can be understood that, based on this activation or deactivation information, the terminal can determine that the length or range of the validity period of the attached PRACH resource activation has not changed. Simultaneously, the terminal can also determine that the start and end times of the associated attached PRACH resource activation or deactivation have not changed. Correspondingly, the terminal can also determine which attached PRACH resources are activated or deactivated as the time units decrease.

[0103] Optionally, in this embodiment of the application, when the first bit in the first indication information is a second value, the activation or deactivation related information indicates that the activation validity period of the additional PRACH resource associated with the first bit is suspended.

[0104] It is understandable that when the bit associated with the additional PRACH resource indicates the second value, the terminal considers the additional PRACH resource temporarily deactivated. At this time, the validity period is paused and does not decrease until the first indication information indicates the first value again, or the validity period is reconfigured. It is understandable that based on this activation or deactivation information, the terminal can determine that the validity period or time range of the activated additional PRACH resource has been updated because the end time of activation or deactivation has changed. Simultaneously, the terminal can also determine which additional PRACH resources are activated or deactivated. Another possibility is that when the bit associated with the additional PRACH resource indicates the second value, the terminal considers the additional PRACH resource temporarily deactivated, and at this time, the validity period decreases normally; that is, the validity period decreases over time regardless of whether the associated additional PRACH resource is activated or deactivated. It is understandable that based on this activation or deactivation information, the terminal can determine that the validity period or time range of the activated additional PRACH resource has not been updated. However, at this time, which additional PRACH resources within the validity period are activated or deactivated has changed, and the terminal can determine this information.

[0105] Optionally, in this embodiment, when both the second bit and the first bit in the first indication information are of a 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 decreases. It can be understood that, based on this activation or deactivation related information, the terminal can determine that the duration or range of the activation validity period of the additional PRACH resource has not changed. Simultaneously, the terminal can also determine that the start and end times of the activation or deactivation of the associated additional PRACH resource have not changed. Correspondingly, the terminal can also determine which additional PRACH resources are activated or deactivated as the time unit decreases.

[0106] It is understandable that the attached PRACH resource is associated with two bits: one bit indicates whether the expiration date has been reset, and the other bit indicates whether the expiration date has been decremented. Compared to the method of using only one bit to indicate whether the expiration date has been reset, this avoids the terminal being unable to determine whether the attached PRACH resource is activated when it has not received any indication information.

[0107] Optionally, in this embodiment, when the second bit in the first indication information is a first value and the first bit in the first indication information is a 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, based on this activation or deactivation related information, the terminal can determine that the duration or range of the validity period of the activation of the additional PRACH resource has been updated because the end time of activation or deactivation has changed. Correspondingly, the terminal also needs to re-determine whether the additional PRACH resource is activated or not.

[0108] It should be noted that whether the validity period decreases can also refer to whether the validity period is suspended. That is, the validity period not decreasing is equivalent to the validity period being suspended, and the validity period decreasing is equivalent to the validity period not being suspended. It can be understood that the validity period decreasing means that the associated additional PRACH resource is considered to be active, and the validity period being suspended means that the associated additional PRACH resource is considered to be deactivated.

[0109] 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 reduced or suspended; 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.

[0110] Alternatively, the first bit is used to determine whether the additional PRACH resource associated with the bit is active; the second bit is used to determine whether the validity period of the active additional PRACH resource associated with the bit is reset.

[0111] Alternatively, the first bit is used to determine whether the additional PRACH resource associated with the bit is active; the second bit is used to determine whether the validity period of the active additional PRACH resource associated with the bit is reduced or suspended.

[0112] Optionally, in this embodiment, the first bit can be the first bit, and the second bit can be the bit following the first bit. It is understood that the first bit can also be the second bit associated with the PRACH resource, in which case the second bit is the bit preceding the first bit.

[0113] For example, the second value mentioned above is 0. It can be understood that the second value mentioned above can also be 0.

[0114] Optionally, in this embodiment of the application, if the first bit in the first indication information is a second value or if the first indication information is not received, the validity period of the activation of the additional PRACH resource associated with the first bit is reduced.

[0115] It should be noted that the additional PRACH resources associated with each bit are configured by the network-side device. That is, the additional PRACH resources associated with each indication bit are determined and are unrelated to whether or not the first indication information is received. Therefore, even if the first indication information is not received, the above activation or deactivation related information can indicate that the validity period of the activation of the additional PRACH resources associated with the first bit is decreasing. In other words, the terminal believes that the validity period of the activation of the additional PRACH resources associated with the first bit is decreasing.

[0116] Optionally, in this embodiment of the application, when the first bit in the first indication information is a second value, the activation or deactivation related information indicates that the additional PRACH resource associated with the first bit is deactivated until an indication that the first bit is the first value is received. It can be understood that, at this time, as long as an indication that the first bit is the second value is received, the associated PRACH resource is considered deactivated.

[0117] Optionally, in this embodiment of the application, when the first bit in the first indication information is a second value, the activation validity period of the additional PRACH resource associated with the first bit of the activation or deactivation related information indication does not decrease until an indication that the first bit is a first value is received. It can be understood that when the first bit is a second value, the validity period is suspended until the first bit is a first value.

[0118] Optionally, in this embodiment, whether to deactivate the additional PRACH resource or reduce its validity period in the absence of the first indication information is determined based on the previously received indication information. It is understood that when the terminal fails to receive the first indication information for various reasons, it determines the activation or deactivation information of the additional PRACH resource based on previously received indication information. For example, if the previously received indication information indicated that some additional PRACH resources were active, they are still considered active; or, if the previously received indication information indicated that the validity period was decreasing normally, the validity period is also considered to be decreasing normally.

[0119] Optionally, in this embodiment of the application, if the first bit in the first indication information is the second value and no indication information with the first bit being the first value has been received, the activation or deactivation related information indicates that the additional PRACH resource in the first time window is activated. The first time window is the current period within the validity period or at least one period after the current period within the validity period.

[0120] It's understandable that the terminal might not have received the relevant signaling for validity period settings or updates. When it can only be determined that the current validity period is within the specified timeframe, it's necessary to determine whether subsequent additional PRACH resources are activated. Since it's certain that the current validity period is within the specified timeframe, the terminal, based on this information, considers the additional PRACH resources within the first time window to be activated.

[0121] It should be noted that the network-side device periodically sends the first indication information. If the terminal has received a first indication information where the first bit has the second value, and has not received another first indication information where the first bit has the first value, the terminal will activate or deactivate the relevant information indicating that the additional PRACH resource within the first time window is active. It can be understood that when the first bit has the second value, it indicates that the activation validity period is decreasing normally. Therefore, even if the terminal has not received a first indication information indicating that the validity period has taken effect, it can at least determine that the additional PRACH resource is active within the current validity period.

[0122] Optionally, in this embodiment of the application, when a first indication information with a first bit of a first value has been received, the above-mentioned activation or deactivation related information indicates that the additional PRACH resources within the first time window are activated.

[0123] Optionally, in this embodiment of the application, if a first indication message with the first bit having the first value has been received within the second time window, the terminal considers the additional PRACH resource within the first time window to be active when a first indication message with the first bit having the second value is received. It is understood that the above condition is only considered valid if the terminal has received a first indication message with the first bit having the first value within the second time window; otherwise, the additional PRACH resource within the first time window cannot be considered active.

[0124] Optionally, in this embodiment, the end position of the second time window is the moment when the first indication information with the first bit having the second value is received, or before that moment. The second time window can be at least one time unit, which may include any of the following: millisecond, time slot, symbol, subframe, frame, DRX period, paging period, random access resource configuration period, SSB-RO mapping period, and SSB-RO mapping pattern period.

[0125] Optionally, in this embodiment, the additional PRACH resource is unavailable if no first indication information for activating the additional PRACH resource is received. It is understood that after configuring the validity period information of the additional PRACH resource on the network side, a first indication information is required for the configuration to be considered effective.

[0126] Optionally, in this embodiment, the activation or deactivation start time of the above-mentioned additional PRACH resources is any one of the following:

[0127] The first configuration period, or the first SSB-RO mapping pattern period, or the first SSB-RO mapping period of the additional PRACH resources within the first validity period mentioned above;

[0128] The first additional PRACH resource within the first validity period mentioned above;

[0129] The next paging cycle or the next DRX cycle;

[0130] Current paging cycle or current DRX cycle;

[0131] The time of receiving the aforementioned first instruction information;

[0132] The location of the first additional PRACH resource after the moment when the first indication information is received;

[0133] The time at least one time unit after the first instruction information is received;

[0134] The location of the first additional PRACH resource at least one time unit after the first indication information is received.

[0135] Optionally, in the embodiments of this application, the above-mentioned at least one time unit includes at least one of the processing time of the first indication and the feedback time of the Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK).

[0136] Optionally, in this embodiment of the application, the association between the above-mentioned additional PRACH resources and the first indication information includes: the identifier of each additional PRACH resource is associated with a bit in the first indication information.

[0137] It can be understood that each bit in at least one bit of the first indication information mentioned above is associated with an additional PRACH resource.

[0138] Optionally, in this embodiment of the application, the identifier of each additional PRACH resource is associated with a bit in the first indication information, including: the additional PRACH resource identified as i is associated with the (i+1)th bit in the first indication information, where i is a positive integer.

[0139] 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, when configuring additional PRACH resources, the network-side device assigns an ID to each additional PRACH resource. Thus, if the first indication information activates or deactivates additional PRACH resources in groups, only one bitmap is needed to indicate which group of additional PRACH resources has activation or deactivation information. It can also be understood that different additional PRACH resources can be configured with the same identifier, i.e., grouping additional PRACH resources. In particular, if additional PRACH resources are not grouped, then the first indication information only needs one bit to indicate the activation or deactivation information of all additional PRACH resources.

[0140] Optionally, in this embodiment of the application, the second configuration information mentioned above includes at least one of the following:

[0141] SSB index;

[0142] Additional PRACH configuration index;

[0143] The third information corresponding to the configuration information of the first PRACH includes at least one of the following: scaling factor and offset value;

[0144] The relationship between the additional PRACH resource and the first PRACH resource;

[0145] PRACH resource parameters;

[0146] Power parameters;

[0147] Competition and measurement-related parameters.

[0148] It should be noted that the first PRACH mentioned above can be a legacy PRACH, or a PRACH that has been configured or exists on the network-side device, or a PRACH corresponding to an existing standard version.

[0149] Optionally, in this embodiment of the application, the above-mentioned SSB index is an SSB index that has a quasi-co-location (QCL) relationship with the attached PRACH resource.

[0150] Optionally, in this embodiment of the application, the configuration index of the additional PRACH is used to determine the additional PRACH resource from the first table, which includes at least one PRACH configuration index and the corresponding Preamble format, PRACH resource configuration period, and the radio frame position, subframe position, start symbol, etc. where the PRACH resource is located.

[0151] It can be understood that the terminal determines the PRACH resource corresponding to the additional PRACH configuration index from the first table based on the additional PRACH configuration index configured by the network-side device, and uses it as the aforementioned additional PRACH resource.

[0152] For example, the first table above is shown in Table 1. The first PRACH is indicated by the PRACH configuration index line 5, and the additional PRACH is indicated by the additional PRACH configuration index line 17. Thus, the temporal resource of the first PRACH is the subframe 4 of the even-numbered SFN, and the temporal resource of the additional PRACH configuration is the subframe 4, 9 in each SFN. The number of temporal PRACHs within the PRACH slot.

[0153] Table 1

[0154]

[0155] Optionally, in the embodiments of this application, the configuration information of the first PRACH includes at least one of the following: the subframe of the System Frame Number (SFN), the start symbol of the SFN, the number of PRACH slots of the SFN, the number of PRACH opportunities of the SFN, and the PRACH length of the SFN.

[0156] For example, the aforementioned additional PRACH resources are determined based on the third information corresponding to the configuration information of the first PRACH. In Table 1 above, n is configured. f x, y, subframe number, scaling factor (or offset) of the start symbol. n f y is the location of the radio frame where the RO is located, x is the configuration period of the RO, and y is used to determine n. f The median value.

[0157] For example, the first PRACH is configured with index line 5, so the time domain resource of the first PRACH is subframe 4 of an even number of SFNs (SFN 0, 2, 4...). If the network-side device is configured with 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 is configured with 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 is configured with SFN-offset as m and subframe-offset or slot-offset as n, then the additional PRACH resource is subframe (4+n) of SFN (n, 2+n, 4+n...).

[0158] For example, if xn is configured as a scaling factor for x, then the x' of the additional PRACH resource 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.

[0159] Optionally, in this embodiment of the application, the relationship between the additional PRACH resource and the first PRACH resource (legacy PRACH resource) includes any of the following:

[0160] The additional PRACH resource does not overlap with the first PRACH resource;

[0161] The additional PRACH resource overlaps with the first PRACH resource;

[0162] The resource locations of the additional PRACH resource and the first PRACH resource are spaced apart;

[0163] The first PRACH resource is masked by the network and used as an additional PRACH resource.

[0164] Optionally, in this embodiment, the additional PRACH resource overlaps with the first PRACH resource. Specifically, the overlapping resource is used for mapping SSBs and ROs of the first PRACH resource and is not used as an additional PRACH resource; or, the overlapping resource can be used for mapping SSBs and ROs, and the ROs of the additional PRACH resource are invalid after mapping; or, the ROs of the additional PRACH resource and the first PRACH resource cannot partially overlap, but can completely overlap; or, in the case where one SSB maps multiple ROs, the resources of the additional PRACH resource that do not overlap with the first PRACH resource are preferentially masked by the network.

[0165] Optionally, in the embodiments of this application, the above-mentioned interval is related to at least one of the sub-carrier space (SCS) and the sequence length of PRACH.

[0166] Optionally, in this embodiment, the first PRACH resource that is network-masked is used as an additional PRACH resource. Specifically, the RO of the first PRACH resource that is network-masked cannot be unmasked; or, if the RO of the first PRACH resource that is network-masked is unmasked, the RO is no longer used as an additional PRACH resource.

[0167] Optionally, in the embodiments of this application, if RO is no longer used as an additional PRACH resource, the additional PRACH resource and SSB are remapped, or the mapping relationship between the additional PRACH resource and SSB remains unchanged and RO is unavailable.

[0168] It is 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 4:

[0169] Scenario 1: The network-side device configures additional PRACH resources to avoid overlap with the first PRACH (or at least the PRACH resource without a mask), or in other words, the terminal does not expect the network-side device to configure overlapping PRACH and additional PRACH. Overlapping scenarios include at least one of the following: partial or complete overlap in the time domain, and partial or complete overlap in the frequency domain.

[0170] Case 2: The network-side device can be configured to have overlapping additional PRACH resources with the first PRACH (or at least the PRACH resource without a mask). The overlapping includes at least one of the following: partial or complete overlap in the time domain, and partial or complete overlap in the frequency domain. For overlapping resources, at least one of the following methods (1) to (4) can be used for processing:

[0171] Method (1) Overlapping resources can only be used for the mapping of the first PRACH for SSB-RO and cannot be used as an additional PRACH. In other words, when overlap occurs, the additional RO is invalid and is not mapped during the SSB-RO mapping process of the additional RO. In other words, when overlap occurs, the overlapping RO is considered not to belong to the additional PRACH resource.

[0172] In other words, the effectiveness of the added RO is determined by the legacy RO or the legacy RO without the mask removed.

[0173] Method (2) Overlapping resources can be mapped to SSB-RO, but after mapping, the additional RO is considered invalid.

[0174] In method (3), ROs cannot partially overlap, but they can completely overlap, or in other words, they can share ROs. This can be understood as the terminal not expecting ROs to be configured as partially overlapping, or when they partially overlap, they can be processed according to method (1) or method (2) above. When they completely overlap, legacy ROs and additional ROs can be distinguished by different preambles.

[0175] Method (4) When an SSB corresponds to multiple ROs, the network-side device configures the PRACH mask so that the mapped ROs are used for PRACH transmission. The network-side device prioritizes masking resources that do not overlap.

[0176] Case 3: The network-side device is configured with at least one of the time-domain and frequency-domain locations of the additional RO, and the first PRACH (or at least a PRACH resource without a mask) satisfies a certain interval. Optionally, this interval is related to at least one of the SCS and the sequence length of the PRACH.

[0177] For example, if the temporal domain of the legacy RO is configured in subframe 4, then the temporal domain of the additional RO is in subframe 4 at least two subframes apart.

[0178] Optionally, when the configured additional RO and the first PRACH (or at least the PRACH resource without a mask) do not meet the above interval, the processing method of method (1) or method (2) described above shall be adopted.

[0179] Case 4: A legacy RO that is masked by the network can be configured or indicated as an additional PRACH resource by the network side.

[0180] Optionally, if configured to attach PRACH resources, these ROs cannot be unmasked.

[0181] Optionally, if the masked legacy ROs are unmasked, then those ROs are no longer attached PRACH resources.

[0182] Optionally, the mapping between the SSB and the additional PRACH resources can be re-performed.

[0183] Alternatively, the mapping remains unchanged, but these additional PRACH resources are considered unavailable.

[0184] Optionally, in the embodiments of this application, the above-mentioned PRACH resource parameters (in order to distinguish between the first PRACH and the additional PRACH resources) include at least one of the following: PRACH configuration index, the starting position of the RO frequency domain, the number of ROs multiplexed in the frequency domain, the number of SSBs corresponding to one RO, a subset of SSBs used for additional PRACH, a subset of preambles used for additional PRACH, and PRACH mask indication.

[0185] Optionally, in this embodiment, the power parameters include at least one of the following: powerramping and preambleReceivedTargetPower. Since different configurations of the additional PRACH may result in different target powers, different power parameters need to be configured to ensure that the terminal's transmission power remains consistent.

[0186] Optionally, in the embodiments of this application, the above-mentioned competition and measurement-related parameters include at least one of the following: the size of the Random Access Response (RAR) window, the signal quality (e.g., RSRP) threshold for measuring the SSB, and the competition resolution timer.

[0187] Optionally, in this embodiment of the application, when the validity period of the activation of the additional PRACH resource overlaps with the configuration period of the additional PRACH resource, it includes any one of the following:

[0188] Additional PRACH resources are active during the overlapping time period;

[0189] The additional PRACH resources within the configuration period of the additional PRACH resources where the overlap time occurs are active;

[0190] An additional PRACH resource is active when the configuration cycle in which the additional PRACH resource resides is within the active validity period of the additional PRACH resource.

[0191] In this embodiment, since the activation indication of the additional PRACH resource (i.e., the aforementioned first indication information) is carried in the paging-related DCI (e.g., DCI format 1-0 or DCI format 2-7), and the transmission frequency of these DCIs is related to the paging period, the validity period of the activation of the additional PRACH resource is also measured in paging periods. However, the configuration of the additional PRACH resource is related to the random access resource configuration period (RACH configuration period). Therefore, when the paging period and the random access resource configuration period are different, it is difficult for the validity period of the activation to be perfectly aligned with the random access resource configuration period. Thus, when the validity period of the activation decreases to the last paging period, the scope of the validity period of the activation may only include a portion of the additional PRACH resources within a configuration period. At this time, it needs to be determined whether the additional PRACH resources within this configuration period are activated. As mentioned above, it can be assumed that only the additional PRACH resources within the validity period are activated, even if the additional PRACH resources outside the validity period belong to the same configuration period as the additional PRACH resources within the validity period. Another possibility is that any overlapping portion indicates that all additional PRACH resources within the configuration period are considered active. Yet another possibility is that additional PRACH resources are considered active only if all additional PRACH resources within the configuration period are within their active validity period.

[0192] In this embodiment of the application, for the first validity period or the configuration validity period of the additional PRACH resource, the time length for activating or deactivating the additional PRACH resource can be controlled, and it can still be determined whether the additional PRACH resource is activated when the terminal does not receive relevant activation or deactivation indication information.

[0193] Regarding the association between the aforementioned additional PRACH resources and the first indication information, it is beneficial for network-side devices to more dynamically and flexibly control the activation or deactivation of additional PRACH resources using physical layer or media access control (MAC) layer signaling.

[0194] The group identifier for the aforementioned additional PRACH resources allows network-side devices to manage the activation or deactivation of additional PRACH resources more precisely, for example, by activating different numbers or different beam directions of PRACH resources based on the congestion level in different directions.

[0195] The second configuration information mentioned above is used to help the terminal determine at least one of the following: the resource location, mapping rules, and transmission parameters of the additional PRACH resources.

[0196] It should be noted that additional PRACH resources are introduced to save network energy. When the network is relatively idle, the additional PRACH resources are deactivated, and the network only needs to detect the random access behavior of terminals on a few PRACH resources. When the network is busy, the additional PRACH resources are activated to meet the random access needs of terminals.

[0197] This application provides a resource determination method. A terminal determines second information based on first information. The first information includes at least one of first configuration information and first indication information. The second information includes at least one of additional PRACH resources and information related to the activation or deactivation of the additional PRACH resources. In this solution, since the terminal can determine the additional PRACH resources or related activation or deactivation information based on the configuration information or indication information of the additional PRACH resources, the configuration and indication of the additional PRACH resources can be implemented, thereby achieving network energy saving through the additional PRACH resources.

[0198] This application provides a resource determination method. Figure 3 A flowchart illustrating the resource determination method provided in an embodiment of this application is shown. Figure 3 As shown, the resource determination method provided in this application embodiment may include the following steps 301 to 303.

[0199] Step 301: The network-side device sends the first information to the terminal.

[0200] In this embodiment of the application, the first information is used to determine the second information.
