It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.
[0033] The following will provide an exemplary description of the technical terms used in this application:
[0034] 1) Random access procedure
[0035] In related technologies, the random access procedure includes contention-based random access and non-contention-based random access procedures. In a contention-based four-step random access procedure, the UE first sends Msg1 to the network, which includes a preamble. After detecting the preamble, the network sends Msg2 or a Random Access Response (RAR) message, which includes the number of the preamble detected by the network and the uplink radio resources allocated to the UE to send Msg3. After receiving Msg2, the UE confirms that at least one of the preamble numbers carried in Msg2 matches the number of its own preamble. Then, according to the resources indicated by the RAR, it sends Msg3 containing contention resolution information. After receiving Msg3, the network sends Msg4 containing contention resolution information. Upon receiving Msg4, the UE confirms that the resolution information is consistent with what it sent in Msg3, thus completing the four-step random access procedure.
[0036] For example, the network side includes uplink grant (UL grant) information in the RAR to indicate the scheduling information for the Msg3 Physical Uplink Shared Channel (PUSCH), and includes information such as RAPID (RACHpreamble ID), TC-RNTI, and TA. If the network side does not receive the Msg3 PUSCH, it can schedule the retransmission of the Msg3 PUSCH in the Physical Downlink Control Channel (PDCCH) scrambled with TC-RNTI.
[0037] In a contention-based random access procedure, different UEs randomly select a preamble for transmission. This means different UEs might select the same preamble for transmission on the same time-frequency radio resources (e.g., Random Access Occasion (RO) resources), a situation known as UE preamble conflict. In this case, different UEs will receive the same RAR (Range Access Registry). Therefore, different UEs will transmit the Msg3 PUSCH according to the scheduling information in the RAR UL grant. Since current technology does not support repeated transmission of the Msg3 PUSCH, the network can only decode one UE-transmitted PUSCH (containing contention resolution information) on a single Msg3 PUSCH scheduling resource. Therefore, the network will include the contention resolution information received in Msg3 in Msg4. If the contention resolution information received by the UE in Msg4 matches the contention resolution information transmitted by the UE in the Msg3 PUSCH, the UE considers the contention resolution successful. If they do not match, the contention resolution is considered unsuccessful.
[0038] If contention resolution fails, the UE will reselect RACH transmission resources, perform PRACH transmission, and attempt another random access attempt.
[0039] In NR Rel-16, 2-step RACH was introduced. The first step is for the UE to send MsgA to the network. Upon receiving MsgA, the network sends MsgB to the UE. If the UE does not receive MsgB within a certain time, it increments a counter counting the number of MsgA transmissions and retransmits MsgA. If the counter reaches a certain threshold, the UE switches from a 2-step random access procedure to a 4-step random access procedure. MsgA includes a MsgA preamble and a MsgA PUSCH. The preamble is transmitted on the RO (Redirecting Access Point) used for 2-step RACH, and the PUSCH is transmitted on the MsgA PUSCH resources associated with the MsgA preamble and RO. It should be noted that the MsgA PUSCH resources are a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and DMRS resources.
[0040] 2) First random access procedure and second random access procedure
[0041] In this embodiment of the application, the first random access procedure is a random access procedure used to indicate the first characteristic.
[0042] In this embodiment of the application, the second random access procedure is a random access procedure used to indicate the second characteristic.
[0043] In some possible embodiments,
[0044] The first feature mentioned above is used for small data transmission, while the second feature mentioned above is used for non-small data transmission.
[0045] or,
[0046] The first characteristic mentioned above applies to RedCap UEs, while the second characteristic applies to non-RedCap UEs.
[0047] or,
[0048] The first characteristic mentioned above is the first network slice, and the second characteristic mentioned above is the second network slice;
[0049] or,
[0050] The first feature mentioned above supports MsgA PUSCH repetition, while the second feature mentioned above does not support MsgA PUSCH repetition.
[0051] In other words, the embodiments of this application can be applied to both MsgA PUSCH resources for small data transmission and MsgA PUSCH resources for non-small data transmission, or more broadly to MsgA PUSC resources used to indicate the first feature and MsgA PUSCH resources used to indicate the second feature. For example, the first feature here can be a RedCap UE, and the second feature can be a non-RedCap UE.
[0052] 3) Small data transmission
[0053] The characteristic of small data transmission is that for UEs in a non-connected state (e.g., idle or inactive), it avoids excessive signaling overhead caused by Radio Resource Control (RRC) state transitions and RRC connection establishment processes, and completes the purpose of small data transmission through a very simple signaling process.
[0054] The key feature of the small data transmission scheme is that the UE's DRB is currently in a suspended state, rather than a released state. Therefore, before sending a Resume Request message, the UE can restore the Data Radio Bearer (DRB) and then use RRC signaling to piggyback the small data. At this point, it can transmit data on the DRB just like a connected UE. This avoids state transitions and achieves efficient small data transmission with minimal signaling overhead.
[0055] Since small data transmission uses DRB transmission and AS security is activated, necessary security protections can be provided for the data, such as data encryption and integrity protection. From a security perspective, because the UE may have moved to another base station while in the suspended state, the security key used by the UE to retransmit packets needs to be updated. The update method is to perform the next-hop key update operation based on the parameters provided by the network side when the UE entered the suspended state for calculating the next-hop key.
[0056] In small data transmission, the data to be transmitted is carried on the Dedicated Traffic Channel (DTCH) and multiplexed with an uplink RRC Connection Resume Request message before transmission. Similarly, if there is a downlink recovery message, it can also be carried on the DTCH and multiplexed with a downlink RRCConnectionRelease message for transmission. Both uplink and downlink data are encrypted using the updated next key.
[0057] In addition, small data can also be transmitted on the MsgA PUSCH during the 2-step RACH process, or on the PUSCH resource scheduled by the configured grant in the RRCinactive state.
[0058] It should be noted that small data transfers during 2-step RACH and 4-step RACH processes are called RACH-based small data transfers, while small data transfers during PUSCH processes scheduled based on configured grants (CG) are called CG-based small data transfers.
[0059] In related technologies, for small data transmission based on 2-step RACH, when MsgA preamble and MsgA preamble that does not support small data are transmitted on a shared RO, configuring MsgA PUSCH resources used for sending small data transmissions and those not used for sending small data transmissions independently would incur significant signaling overhead and could potentially lead to conflicts between the two types of MsgA PUSCH resources. When small data transmissions and non-small data transmissions use independent ROs, MsgAPUSCH resources can be allocated independently because their respective PRACH slots may be different.
[0060] The technical solution provided in this application embodiment is: considering how to efficiently configure appropriate MsgA PUSCH resources for small data transmission, depending on whether shared RO resources are used in the small data transmission process.
[0061] 4) Random Access Occasion (RO)
[0062] PRACH Occasion refers to the time-frequency resources required to transmit a PRACH sequence.
[0063] It should be noted that, in the embodiments of this application, SDT 2-step RO refers to the RO used in the 2-step RACH random access process for small data transmission. non-SDT 2-step RO refers to the RO used in the 2-step RACH random access process for non-small data transmission. SDT 4-step RO refers to the RO used in the 4-step RACH random access process for small data transmission. non-SDT 4-step RO refers to the RO used in the 4-step RACH random access process for non-small data transmission.
[0064] 5) PUSCH Occasion (PO)
[0065] PUSCH Occasion refers to the time-frequency resources required to send a PUSCH.
[0066] The resource determination method, apparatus, equipment, and medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0067] This application provides a resource determination method, such as... Figure 2 As shown, the resource determination method may include the following steps 201 to 204:
[0068] Step 201: The network-side device configures the target resource configuration for the UE.
[0069] Step 202: The UE obtains the target resource configuration.
[0070] Step 203: The UE determines the first target resource based on the target resource configuration.
[0071] Step 204: The network-side device determines the second target resource based on the target resource configuration.
[0072] In this embodiment of the application, the target resource configuration includes: a first resource configuration and / or a second resource configuration.
[0073] In this embodiment, the first resource configuration is used to configure the first resource in the first random access process; the second resource configuration is used to configure the second resource in the second random access process.
[0074] In this embodiment of the application, the first target resource is used in the first random access procedure.
[0075] In this embodiment of the application, the second target resource is used in the first random access procedure.
[0076] It should be noted that the first target resource and the second target resource mentioned above can be the same resource.
[0077] In the embodiments of this application, the first random access procedure is a random access procedure for indicating a first characteristic (e.g., a 2-step random access procedure for indicating a first characteristic, or a 4-step random access procedure for indicating a first characteristic); the second random access procedure is a random access procedure for indicating a second characteristic (e.g., a 2-step random access procedure for indicating a second characteristic, or a 4-step random access procedure for indicating a second characteristic).
[0078] In some possible embodiments, the first resource is the PUSCH resource in the MsgA of the first random access procedure; the second resource is the PUSCH resource in the MsgA of the second random access procedure.
[0079] Optionally, in this embodiment of the application, after the UE determines the first target resource based on the target resource configuration, it can send PUSCH on the first target resource; correspondingly, after the network-side device determines the second target resource based on the target resource configuration, it can send PUSCH on the second target resource.
[0080] Optionally, in embodiments of this application, the UE and / or network-side device may also combine a third resource configuration to determine the first target resource.
[0081] In some possible embodiments, step 203 above may include step 203a as follows:
[0082] Step 203a: The UE determines the first target resource based on the target resource configuration and the third resource configuration.
[0083] In some possible embodiments, step 204 above may include step 204a as follows:
[0084] Step 204a: The network-side device determines the second target resource based on the target resource configuration and the third resource configuration.
[0085] For example, the third resource configuration described above is used to configure the first random access event RO and other ROs. The other ROs include at least one of the following: a second RO, a third RO, and a fourth RO.
[0086] For example, the first RO is: the RO used to indicate the two-step random access of the first feature;
[0087] The second RO is: the RO used to indicate the two-step random access for the second characteristic;
[0088] The third RO is: the RO used to indicate the 4-step random access of the first characteristic;
[0089] The fourth RO is the RO used to indicate the 4-step random access of the second characteristic.
[0090] For example, the first RO described above and other ROs satisfy at least one of the following:
[0091] The first RO is an independently configured RO;
[0092] The first RO and the second RO are ROs with a common configuration;
[0093] The first RO and the third RO are ROs with a common configuration;
[0094] The first RO and the fourth RO are ROs with a common configuration.
[0095] For example, the relationship between the first RO and other ROs satisfies at least one of the following:
[0096] The first RO is an independently configured RO;
[0097] The first RO and the second RO are shared;
[0098] The first and third RO units share the same space.
[0099] The first and fourth RO units share the same space.
[0100] For example, taking Small Data Transfer (SDT) as an example, the first RO mentioned above can be an SDT 2-step RO, the second RO mentioned above can be a non-SDT 2-step RO, the third RO mentioned above can be an SDT 4-step RO, and the fourth RO mentioned above can be a non-SDT 4-step RO. Here, the SDT 2-step RO refers to the RO used in the 2-step RACH random access process of SDT; the non-SDT 2-step RO refers to the RO used in the 2-step RACH random access process of non-SDT; the SDT 4-step RO refers to the RO used in the 4-step RACH random access process of SDT; and the non-SDT 4-step RO refers to the RO used in the 4-step RACH random access process of non-SDT.
[0101] Furthermore, the aforementioned SDT 2-step RO may have one or more of the following relationships regarding whether it is reused with other ROs, meaning that the UE and network-side equipment can determine the resource configuration of the MsgA PUSCH based on these relationships:
[0102] (1) The RO allocated independently by the above SDT 2-step RO does not share RO with other RAs.
[0103] (2) The above-mentioned SDT 2-step RO and non-SDT 2-step RO share;
[0104] (3) The above-mentioned SDT 2-step RO and SDT 4-step RO share;
[0105] (4) The above-mentioned SDT 2-step RO and non-SDT 4-step RO share.
[0106] It should be noted that when the first RO is shared with other ROs, the shared ROs can be all ROs or only some ROs.
[0107] For scenarios where the third resource configuration is used to configure the first RO and the second RO as ROs with common configurations (i.e., the first RO and the second RO are shared):
[0108] In some possible embodiments, step 203a above may include the following step 203a1:
[0109] Step 203a1: The UE determines the first target resource based on the target resource configuration, the third resource configuration, and the target method.
[0110] In some possible embodiments, step 204a above may include the following step 204a1:
[0111] Step 204a1: The network-side device determines the second target resource based on the target resource configuration, the third resource configuration, and the target method.
[0112] The aforementioned target methods include at least one of the following:
[0113] The first and second resources are reused in the frequency domain;
[0114] The first and second resources are reused in the time domain;
[0115] The first and second resources are reused simultaneously in both the time and frequency domains;
[0116] The first resource and the second resource use different DMRS resources on the same time domain resources and frequency domain resources;
[0117] The source is determined based on the leading sequence corresponding to the first resource and the leading sequence corresponding to the second resource;
[0118] Determined based on the target preamble sequence applied during the first random access procedure;
[0119] The parameters are determined based on the MCS parameters configured for the first and second resources, respectively.
[0120] In some examples, the above target method is configured by the network-side device.
[0121] In some examples, the sources of the leading sequence corresponding to the first resource and the leading sequence corresponding to the second resource include at least one of the following:
[0122] The leading sequence corresponding to the first resource is any one of the first leading sequence or the second leading sequence;
[0123] The leading sequence corresponding to the second resource is either the first leading sequence or the second leading sequence.
[0124] In some examples, the first preamble sequence is configured by the network-side device; and / or, the second preamble sequence is configured by the network-side device.
[0125] In some examples, the aforementioned target preamble sequence group is: at least one independently configured third preamble sequence, which is: a random access sequence for indicating two-step random access of the first characteristic; or,
[0126] The aforementioned second random access procedure is configured with a first preamble sequence and a second preamble sequence. The second random access procedure only applies the first preamble sequence, and the target preamble sequence is the second preamble sequence.
[0127] For example, the following will use SDT as the first characteristic and non-SDT as the second characteristic to illustrate the above target method.
[0128] For example, when an SDT 2-step RO is shared with a non-SDT 2-step RO, the above-mentioned objective includes at least one of the following:
[0129] (1) SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources are reused in the frequency domain.
[0130] In this approach, when SDT MsgA PUSCH resources are multiplexed with non-SDT MsgA PUSCH resources in the frequency domain, the SDT MsgA PUSCH Occasion can reuse the time-domain configuration information of the non-SDT MsgA PUSCH occasion. However, additional information can be configured for each PUSCH occasion in the frequency domain, such as the size of each PUSCH Occasion and / or the number of PUSCH occasions in that frequency domain. For example, the frequency offset of the SDT MsgA PUSCH Occasion can be associated with the start or end position of the non-SDT MsgA PUSCH Occasion in the frequency domain; or, the frequency offset of the SDT MsgA PUSCH Occasion can be associated with the first PRB of the active UL BWP.
[0131] For example, such as Figure 3 As shown, SDT and non-SDT share a RO, which is mapped to an SSB. This RO is allocated a total of 8 preambles (e.g., Figure 3 In the SDT (Preamble 0 to Preamble 7) PUSCH resources, the first four (Preamble 0 to Preamble 3) are used for non-SDT, and the last four (Preamble 4 to Preamble 7) are used for SDT. SDT MsgA PUSCH resources and non-SDT PUSCH resources are multiplexed in the frequency domain, with each PO having a size of 16 PRBs and 8 PRBs respectively. The time domain resource allocation is the same, with 4 POs for each domain. The 4 POs of SDT are mapped to preamble 4 to preamble 7, and the 4 ROs of non-SDT are mapped to preamble 0 to preamble 3.
[0132] (2) SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources are reused in the time domain.
[0133] In this approach, when SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources are multiplexed in the time domain, the SDT MsgA PUSCH Occasion can reuse the time domain configuration information of the non-SDT MsgA PUSCH occasion. However, additional information for each PUSCH occasion in the time domain can be configured, such as the size of each PUSCH Occasion and / or the number of PUSCH occasions in that frequency domain. For example, the time offset of the SDT MsgA PUSCH Occasion is associated with the time domain start or end position of the non-SDT MsgA PUSCH Occasion; or, the time offset of the SDT MsgA PUSCH Occasion is associated with the time domain start or end position of the PRACH slot.
[0134] It should be noted that the time offset mentioned above can be in units of the following time: frame, subframe, slot, and PRACH slot (slot during random access). The slot corresponds to the PRACH subcarrier spacing, the SDT MsgA PUSCH subcarrier spacing, the non-SDT MsgA PUSCH subcarrier spacing, or the maximum subcarrier spacing among these.
[0135] For example, such as Figure 4 As shown, SDT and non-SDT share a RO, which maps to an SSB, allocating a total of 8 preambles (e.g. Figure 4 The SDT (Preamble 0 to Preamble 7) is divided into four preambles: the first four (preamble 0 to preamble 3) are used for non-SDT, and the last four (preamble 4 to preamble 7) are used for SDT. SDT MsgA PUSCH resources and non-SDT PUSCH resources are multiplexed in the time domain, each with its own time-domain offset relative to the PRACH slot where the RO (Reallocator) resides. The frequency domain resource allocation is the same, with four POs for each. The four POs of the SDT are mapped to preambles 4 to 7, and the four ROs of the non-SDT are mapped to preambles 0 to 3.
[0136] (3) SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources are reused in both the time and frequency domains.
[0137] It should be noted that the relevant explanations can be found in the first two points, and will not be repeated here to avoid repetition.
[0138] For example, such as Figure 5 As shown, SDT and non-SDT share a RO, which maps to an SSB, allocating a total of 8 preambles (e.g. Figure 5 The PUSCH resources are divided into preambles 0 to 7. The first four (preambles 0 to 3) are used for non-SDT, and the last four (preambles 4 to 7) are used for SDT. The SDT MsgA PUSCH resources and the non-SDT PUSCH resources can be separated in both the time and frequency domains. They each have their own time-domain offset relative to the PRACH slot where the RO resides, as well as a frequency offset, with four POs for each. The four POs of SDT are mapped to preambles 4 to 7, each with a size of 16 PRBs; the four ROs of non-SDT are mapped to preambles 0 to 3, each with a size of 8 PRBs.
[0139] (4) SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources can use different DMRS resources on the same time-frequency resources.
[0140] In this approach, the MsgA PUSCH Occasion of SDT shares time-frequency resources with the MsgA PUSCH resources of non-SDT, using different DMRS resources. The DMRS resources used can be different DMRS interfaces (ports), different DMRS sequences, or both. This saves time-frequency resources, eliminating the need to reserve additional time-frequency resources for MsgA PUSCH in SDT.
[0141] For example, such as Figure 6 As shown, SDT and non-SDT share a RO, which maps to an SSB, allocating a total of 8 preambles (e.g. Figure 6The preambles 0 to 7 are used in the SDT (preamble 0 to preamble 7). The first four (preamble 0 to preamble 3) are used for non-SDT, and the last four (preamble 4 to preamble 7) are used for SDT. The SDT MsgA PUSCH resources are the same as the non-SDT PUSCH resources in the time and frequency domains, but different ports are used within each PO. Port 0 is used for non-SDT, and port 1 is used for SDT.
[0142] (5) SDT MsgA PUSCH resources and non-SDT PUSCH resources can be configured with their own independent MCS parameters.
[0143] (6) Determination of the source of the leading sequence corresponding to the SDT MsgA PUSCH resource and the non-SDT PUSC resource.
[0144] Specifically, the preamble groups corresponding to SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources can be either group A (i.e., the first preamble sequence mentioned above) or group B (i.e., the second preamble sequence mentioned above).
[0145] In other words, there are four possibilities for SDT MsgA PUSCH resources and non-SDT MsgA PUSCH resources:
[0146] 1) The MsgA PUSCH resource corresponding to group A in Non-SDT and the MsgAPUSCH resource corresponding to group A in SDT.
[0147] 2) The MsgA PUSCH resource corresponding to group B in Non-SDT and the MsgAPUSCH resource corresponding to group A in SDT.
[0148] 3) The MsgA PUSCH resource corresponding to group A in Non-SDT and the MsgAPUSCH resource corresponding to group B in SDT.
[0149] 4) The MsgAPUSCH resource corresponding to group B in Non-SDT and the MsgAPUSCH resource corresponding to group B in SDT.
[0150] (7) Determined based on the target preamble sequence used in the first random access process.
[0151] Specifically, the aforementioned target preamble sequence can be an independently configured set of MsgA PUSCH resources for small data transmission, such as group C (i.e., the third preamble sequence mentioned above), which treats the PRACH sequence used for SDT 2-step RA as a preamble group; or, non-SDT MsgA PUSCH can support two preamble groups, namely group A and group B. In this case, the non-SDT random access procedure only uses one preamble group, such as group A, and group B can be used as the target preamble sequence.
[0152] It should be noted that the SDT MsgA PUSCH resources mentioned above refer to the PUSCH resources used for MsgA in the random access procedure of SDT; the non-SDT MsgA PUSCH resources mentioned above refer to the PUSCH resources used for MsgA in the random access procedure of non-SDT; the SDT MsgA PUSCH Occasion (SDT PO) mentioned above refers to the PUSCH Occasion used for MsgA in the random access procedure of SDT; and the non-SDT MsgA PUSCH Occasion (non-SDT PO) mentioned above refers to the PUSCH Occasion used for MsgA in the random access procedure of non-SDT.
[0153] For scenarios where the third resource configuration is used to configure the first resource allocation (RO) as an independently configured RO:
[0154] In some possible embodiments, step 202a above may include step 202a2:
[0155] Step 202a2: The UE determines the first target resource based on the first resource configuration:
[0156] The first resource configuration is configured by the network-side equipment.
[0157] In some possible embodiments, step 302a above may include step 302a2:
[0158] Step 302a2: The network-side device determines the second target resource based on the first resource configuration:
[0159] The first resource configuration is configured by the network-side device itself.
[0160] For example, when the SDT 2-step RO is not shared with the non-SDT 2-step RO, the network side needs to independently configure the MsgA PUSCH resource for the random access procedure corresponding to the first feature.
[0161] It should be noted that, taking SDT as an example, when SDT is transmitted based on MsgAPUSCH during the 2-step RACH process in RRC inactive state, if the SDT RO is shared with the non-SDT RO, the SDT MsgAPUSCH resources and the non-SDT MsgAPUSCH resources can be multiplexed in the frequency domain, time domain, or DMRS, thereby reducing signaling overhead, reducing cell-level frequency resource reservation, and improving resource allocation efficiency. If the SDT RO and the non-SDT RO are not shared, then the MsgAPUSCH resources are configured independently for SDT.
[0162] Optionally, in this embodiment of the application, the UE will determine the selection of SSB according to the configuration of MsgA on the network side, determine the MsgA PRACH resource through the mapping rule from SSB to RO / preamble, and determine the transmission of MsgA PUSCH through the mapping rule from MsgA preamble to MsgAPUSCH and the conflict rule.
[0163] Optionally, in this embodiment of the application, the resource determination method provided in this embodiment of the application may further include the following step 303:
[0164] Step 303: In the event of a conflict between the first resource and the second resource, the UE determines whether to send the first resource based on the first rule.
[0165] For example, the first rule mentioned above includes at least one of the following:
[0166] Do not send the first resource; prioritize the second resource.
[0167] The first information is determined based on the configuration of the network-side device, and the first information is used to indicate whether to send the first resource.
[0168] The UE does not consider there to be a conflict between the first resource and the second resource;
[0169] The UE allows conflicts to occur between the first resource and the second resource;
[0170] Network-side devices communicate only the resources in the first random access process on conflicting resources.
[0171] For example, the first characteristic is SDT and the second characteristic is non-SDT, which will be used as an example to explain the first rule mentioned above.
[0172] For example, when SDT MsgA PUSCH and non-SDT MsgA PUSCH resources (time domain and / or frequency domain) conflict, one or more of the following rules are used to determine whether to send the SDT MsgA PUSCH:
[0173] (1) Do not send SDT MsgA PUSCH, and give priority to non-SDT MsgA PUSCH;
[0174] (2) The network side can be configured to send SDT MsgA PUSCH;
[0175] For example, SDT needs to read network indications to determine whether to actually send SDT MsgAPUSCH on such resources;
[0176] (3) The UE does not believe that the network side will configure a conflict between SDT MsgA PUSCH and non-SDT MsgA PUSCH;
[0177] (4) Such conflicts are allowed. The network side believes that no two UEs will simultaneously select the same PUSCH resource for non-SDT and SDT transmission. If the bet is lost, RAR fallback will be used.
[0178] (5) Allowing such conflicts, the network side ensures that no two UEs will simultaneously select the same PUSCH resource for SDT and non-SDT transmission by only mapping SDT or only mapping non-SDT preamble / RO on the conflicting PUSCH resource.
[0179] Optionally, in this embodiment of the application, the resource determination method provided in this embodiment of the application may further include the following step 304:
[0180] Step 304: In the event of a conflict between the RO resources corresponding to the first resource and the second resource, the UE determines whether to send the first resource based on the second rule.
[0181] For example, the second rule mentioned above includes at least one of the following:
[0182] Do not send the first resource; prioritize random access transmissions on RO resources.
[0183] The first information is determined based on the configuration of the network-side device, and the first information is used to indicate whether to send the first resource.
[0184] The UE does not consider there to be a conflict between the first resource and the RO resource;
[0185] UE allows conflicts between the first resource and the RO resource;
[0186] Network-side devices communicate only the resources in the first random access process on conflicting resources.
[0187] For example, the RO resource corresponding to the second resource mentioned above refers to the RO where the RACH corresponding to the second resource is located.
[0188] For example, the second rule will be explained below with the first characteristic being SDT and the second characteristic being non-SDT.
[0189] When an SDT MsgA PUSCH conflicts with a non-SDT RO resource (time domain and / or frequency domain), one or more of the following rules are used to determine whether to send the SDT MsgA PUSCH.
[0190] (1) Do not send SDT MsgA PUSCH, and give priority to PRACH transmission on non-SDT RO;
[0191] (2) The network side can be configured to send SDT MsgA PUSCH;
[0192] (3) The UE does not believe that the network side will configure a conflict between SDT MsgA PUSCH and non-SDT RO;
[0193] (4) Allowing such conflicts, the network side ensures that the UE will not select this SDT MsgA PUSCH resource for SDT transmission by not mapping any preamble / RO for the SDT MsgA PUSCH resource that conflicts with non-SDT RO.
[0194] It should be noted that although the above embodiments are illustrated using SDT and non-SDT as examples, they are merely examples. In practical applications, the above examples can be applied to random access processes with other characteristics, and this application does not limit them.
