[0389] FIG. 2 is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a communication method for the communication system 100, and the above method comprises:

[0390] Step 2101, the terminal reports the OCC multiplexing capability of the terminal to the network device.

[0391] Optionally, the OCC multiplexing capability described above can be used to indicate whether the terminal supports OCC multiplexing, or can be used to indicate whether the terminal supports OCC multiplexing in different services. Optionally, the OCC multiplexing can refer to OCC multiplexing of NPRACH by the terminal, and the OCC multiplexing of NPRACH can be understood as follows: when different terminals send NPRACH, the NPRACH of the terminal is weighted using the OCC sequence corresponding to the NPRACH of the terminal, where the NPRACH of different terminals correspond to different OCC sequences, and therefore the NPRACH after weighting based on the corresponding OCC sequence is different for different terminals, and each terminal can send the NPRACH after weighting to the network device on the same time-frequency resource. When the network device receives the NPRACH after weighting sent by each terminal on the same time-frequency resource, the network device can perform inverse weighting based on the OCC sequence corresponding to the NPRACH of each terminal to determine the NPRACH of each terminal, thereby realizing OCC multiplexing transmission of multiple terminals on the same time-frequency resource, improving resource utilization, and realizing uplink capacity enhancement and system expansion. More terminals can be supported for uplink transmission under the premise of limited time-frequency resources and limited terminal transmission power, thereby improving uplink transmission efficiency.

[0392] Optionally, in some embodiments, the OCC multiplexing transmission of NPRACH described above can be applied to at least one of the following situations:

[0393] OCC multiplexing transmission of NPRACH in a random access procedure (Normal RACH procedure);

[0394] OCC multiplexing transmission of NPRACH in early data transmission (EDT);

[0395] OCC multiplexing transmission of NPRACH on an anchor carrier;

[0396] OCC multiplexing transmission of NPRACH on non-anchor carriers;

[0397] OCC multiplexing transmission of NPRACH when communicating based on different coverage enhancement levels (CE levels).

[0398] Based on this, in some embodiments, the OCC multiplexing capability reported by the terminal can include at least one of the following:

[0399] whether the terminal supports EDT;

[0400] whether the terminal supports NPRACH transmission on a non-anchor carrier;

[0401] whether the terminal supports OCC multiplexing;

[0402] whether the terminal supports OCC multiplexing when EDT is used;

[0403] whether the terminal supports OCC multiplexing on a non-anchor carrier;

[0404] whether the terminal supports OCC multiplexing on an anchor carrier.

[0405] Optionally, in some embodiments, the terminal can only report whether it supports OCC multiplexing, in which case, when the terminal supports OCC multiplexing, it is by default that the terminal supports OCC multiplexing in a normal RACH procedure, and / or it is by default that the terminal supports OCC multiplexing when EDT is used, and / or it is by default that the terminal supports OCC multiplexing in all services.

[0406] Optionally, in some other embodiments, the terminal can report to the network device whether it supports EDT and / or whether it supports NPRACH transmission on a non-anchor carrier, and the terminal can also report to the network device whether it supports OCC multiplexing. When the terminal reports to the network device that it supports EDT and supports OCC multiplexing, it is considered that the terminal supports OCC multiplexing when EDT is used, i.e., supports OCC multiplexing transmission for NPRACH in an EDT transmission process. Or, when the terminal reports to the network device that it supports NPRACH transmission on a non-anchor carrier and supports OCC multiplexing, it is considered that the terminal supports OCC multiplexing on a non-anchor carrier, i.e., supports OCC multiplexing transmission for NPRACH on a non-anchor carrier.

[0407] Optionally, in some other embodiments, the terminal can directly report to the network device whether it supports OCC multiplexing when EDT is used, and / or whether it supports OCC multiplexing on a non-anchor carrier, and / or whether it supports OCC multiplexing on an anchor carrier.

[0408] Optionally, in some embodiments, the terminal can report the OCC multiplexing capability of the terminal to the network device through first signaling, which may, for example, include at least one of the following: UE assistance information signaling, UE capability signaling, and radio resource control (RRC) signaling.

[0409] Optionally, the terminal reports the OCC multiplexing capability of the terminal to the network device, so that the network device can schedule appropriate resources for the terminal based on the OCC multiplexing capability of the terminal. For example, when the terminal supports OCC multiplexing, the network device can schedule resources for OCC multiplexing to the terminal, and when the terminal does not support OCC multiplexing, the network device can schedule resources for non-OCC multiplexing to the terminal. Alternatively, when the terminal supports OCC multiplexing in a certain service, the network device can schedule resources for OCC multiplexing when scheduling resources for the service, and when the terminal does not support OCC multiplexing in a certain service, the network device can schedule resources for non-OCC multiplexing when scheduling resources for the service. In this way, the terminal can be accurately and effectively managed, and the resources of the terminal can be reasonably managed and scheduled.

[0410] Step 2102: The network device sends configuration information to the terminal.

[0411] Optionally, the configuration information can be used to configure at least one first resource set and / or at least one second resource set; wherein the first resource set can include one or more resources, and the one or more resources in the first resource set can be used for OCC multiplexing transmission of NPRACH; and the second resource set can include one or more resources, and the one or more resources in the second resource set can be used for non-OCC multiplexing transmission of NPRACH.

[0412] From the above, in the embodiments of the present disclosure, the "resources for OCC multiplexing (i.e., the first resource set)" and the "resources for non-OCC multiplexing (i.e., the second resource set)" are independent of each other, thereby avoiding mutual interference between OCC multiplexing transmission and non-OCC multiplexing transmission, and ensuring the communication efficiency and communication stability of both OCC multiplexing transmission and non-OCC multiplexing transmission.

[0413] Optionally, when the network device sends the configuration information to the terminal, the network device can send the configuration information to the terminal based on the OCC multiplexing capability of the terminal. For details of how the network device sends the configuration information to the terminal based on the OCC multiplexing capability of the terminal, refer to the description of step 2101 above.

[0414] Optionally, in some embodiments, the network device can send configuration information corresponding to at least one carrier to the terminal, wherein the same configuration information is used for different carriers, i.e., only one configuration information is configured for different carriers, and the same configuration information is shared by different carriers; or, independent configuration information is used for different carriers, i.e., the configuration information is independently configured for different carriers, and the independent configuration information corresponding to different carriers can be the same or different. Optionally, the different carriers here can refer to different types of carriers, which can optionally include anchor carriers and non-anchor carriers; or, the different carriers can refer to different non-anchor carriers.

[0415] Optionally, in some embodiments, the network device can send configuration information corresponding to at least one CE Level to the terminal, wherein the same configuration information is used for different CE Levels, i.e., only one configuration information is configured for different CE Levels, and the same configuration information is shared by different CE Levels; or, independent configuration information is used for different CE Levels, i.e., the configuration information is independently configured for different CE Levels, and the independent configuration information corresponding to different CE Levels can be the same or different.

[0416] Optionally, in some embodiments, the network device can send NPRACH configuration information corresponding to EDT service to the terminal; and send NPRACH configuration information corresponding to non-data early transmission Non-EDT service to the terminal; wherein the same configuration information is used for EDT service and Non-EDT service, i.e., only one configuration information is configured for EDT service and Non-EDT service, and the same configuration information is shared by EDT service and Non-EDT service; or, independent configuration information is used for EDT service and Non-EDT service, i.e., the configuration information is independently configured for EDT service and Non-EDT service, and the independent configuration information corresponding to EDT service and Non-EDT service can be the same or different.

[0417] Optionally, in some embodiments, the configuration information can also be used to configure the terminal with at least one of the following: OCC sequence length corresponding to at least one OCC sequence, first correspondence relationship, and second correspondence relationship.

[0418] Optionally, the OCC sequence length can be used to determine the OCC sequence, which can be used to realize OCC multiplexing transmission of NPRACH of the terminal; wherein, the OCC sequence length can also be referred to as "multiplexing user number", "OCC multiplexing user number", or "OCC multiplexing maximum user number", etc., which is not limited in the present disclosure;

[0419] Optionally, the first correspondence can be a correspondence between OCC sequence length and the first resource set; wherein different OCC sequence length can correspond to different or same first resource set.

[0420] Optionally, the second correspondence can be a correspondence between OCC sequence length and the second resource set; wherein different OCC sequence length can correspond to different or same second resource set.

[0421] It should be noted that in some embodiments, the configuration information described above can also not be used to configure the OCC sequence length, which can also be agreed upon by the protocol. In addition, in some embodiments, the OCC sequence length can satisfy at least one of the following:

[0422] Different CE Levels of NPRACH correspond to the same OCC sequence length;

[0423] Different CE Levels of NPRACH correspond to independent OCC sequence lengths, wherein the independent OCC sequence lengths corresponding to different CE Levels can be the same or different;

[0424] Different formats of NPRACH correspond to the same OCC sequence length;

[0425] Different formats of NPRACH correspond to independent OCC sequence lengths, wherein the independent OCC sequence lengths corresponding to different formats of NPRACH can be the same or different;

[0426] NPRACHs with different repetition transmission times correspond to the same OCC sequence length;

[0427] NPRACHs with different repetition transmission times correspond to independent OCC sequence lengths, wherein the independent OCC sequence lengths corresponding to NPRACHs with different repetition transmission times can be the same or different;

[0428] Different carriers correspond to the same OCC sequence length;

There is a first correspondence relationship between the first resource set and the OCC sequence length.

[0437] Optionally, in some embodiments, the configuration information described above can be sent through a second signaling. For example, the second signaling can include at least one of the following:

[0442] Optionally, the first resource can be a resource used to send NPRACH.

[0443] The following describes in detail how the terminal determines the first resource from the first resource set and / or the second resource set.

[0444] Optionally, in some embodiments, when the terminal determines the first resource, in response to the terminal supporting OCC multiplexing, if the configuration information does not configure the first resource set but configures the second resource set, the terminal can select the first resource from the second resource set configured by the configuration information; or, if the configuration information configures the first resource set, the terminal can select the first resource from the first resource set configured by the configuration information.

After determining the first CE Level, if the configuration information corresponding to the first CE Level configures the first resource set, the terminal can select the first resource from the first resource set configured by the configuration information corresponding to the first CE Level; or, if the configuration information corresponding to the first CE Level does not configure the first resource set but configures the second resource set, the terminal can select the first resource from the second resource set configured by the configuration information corresponding to the first CE Level.

[0446] Optionally, in yet some embodiments, when the terminal determines the first resource, in response to that the terminal supports OCC multiplexing, the terminal can determine a first CE level corresponding to the NPRACH; then, in response to that the configuration information corresponding to the first CE level configures a first resource set, the terminal can select the first resource from the first resource set configured by the configuration information corresponding to the first CE level; or, in response to that the configuration information corresponding to the first CE level does not configure the first resource set but configures a second resource set, the terminal can determine the first resource by performing a first operation. Optionally, the first operation can include: adding a first threshold to the first CE level to obtain a second CE level, in response to that the configuration information corresponding to the second CE level configures a first resource set, selecting the first resource from the first resource set configured by the configuration information corresponding to the second CE level, in response to that the configuration information corresponding to the second CE level does not configure the first resource set, adding the first threshold to the second CE level to obtain a third CE level, in response to that the configuration information corresponding to the third CE level configures a first resource set, selecting the first resource from the first resource set configured by the configuration information corresponding to the third CE level, in response to that the configuration information corresponding to the third CE level does not configure the first resource set, adding the first threshold to the third CE level to obtain a fourth CE level, and so on until the highest CE level, if the configuration information corresponding to each CE level between the first CE level and the highest CE level does not configure the first resource set, selecting the first resource from the second resource set configured by the configuration information corresponding to the first CE level. Optionally, the first threshold can be agreed by a protocol or configured by a network device, and the first threshold can be 1 for example.

[0654] The following is an exemplary introduction to the above method.

[0655] Optional embodiment 1: NPRACH OCC multiplexing is applicable to at least one of the following transmission mechanisms:

[0656] • Normal random access procedure

[0657] • EDT

[0658] • Anchor carrier

[0659] • Non-anchor carrier

[0660] • Different CE levels

[0661] Optional embodiment 2: Based on optional embodiment 1, the following at least one NPRACH OCC multiplexing related parameter configuration method is adopted:

[0662] • Different carriers, such as Anchor carrier and non-anchor carriers, can be configured with OCC multiplexing related parameters respectively

[0663] • Different CE levels have different NPRACH OCC related configuration parameters

[0664] • Non-EDT and EDT can be configured with different OCC multiplexing related parameters

[0665] Optional embodiment 3: Based on optional embodiment 2, the NPRACH OCC related parameters at least include the following:

[0666] • Separate NPRACH Resource set

[0667] In order to avoid interference between R19 IOT-NTN terminals and legacy terminals, a separate NPRACH Resource set needs to be configured for NPRACH OCC multiplexing

[0668] • OCC multiplexing user number / OCC length

[0669] Optionally, this parameter can be determined based on the protocol agreement, or when the parameter is not configured, the terminal can determine the default value according to the protocol agreement. One possible embodiment is that different CE levels or different repetition numbers correspond to different OCC lengths or OCC multiplexing user numbers.

[0670] For related configuration signaling, for anchor carrier, one possible implementation is shown as follows

[0671] In addition, OCC NPRACH can also be configured in combination with features such as EDT, and for anchor carrier, one possible implementation is shown as follows:

[0672] Or

[0673] In addition, OCC NPRACH can also be configured in combination with features such as EDT, and for non-anchor carrier, one possible configuration signaling implementation is shown as follows:

[0674] Optional embodiment 4: The terminal determines the OCC sequence based on the following manner

[0675] Determine the OCC sequence based on the OCC length and the protocol pre-defined rule

[0676] The protocol pre-defined rule includes but is not limited to the following manner: the terminal generates the OCC index randomly based on the OCC length, or the terminal generates the OCC sequence index based on the UE ID such as TMSI and certain operation rules such as pseudo-random number generation rules

[0677] Further, the terminal determines the specific OCC sequence based on the OCC sequence index, the OCC length, and the protocol pre-defined manner such as the table pre-defined in the protocol. For example, different OCC length corresponds to different OCC table, the terminal first determines the OCC seq table according to the OCC length, and further determines the OCC seq directly according to the OCC seq index. Or, the terminal generates the OCC sequence according to the calculation formula agreed in the protocol, the OCC sequence index and at least one parameter of the OCC length.

[0678] Optionally, the OCC length can also be the default value directly specified in the protocol; for example, the protocol directly specifies that different repetition times correspond to different OCC length, or different CE level corresponds to different OCC length or OCC multiplexing user number

[0679] Optional Embodiment 5: To facilitate eNB to make reasonable NPRACH resource planning and configuration, the terminal can report NPRACH OCC multiplexing terminal capability based on RRC signaling

[0680] • NPRACH OCC multiplexing terminal capability reporting directly through UE assistance information or UE capability signaling

[0681] • Further, for EDT and non-anchor carrier NPRACH OCC multiplexing, the terminal can make separate capability reporting; or,

[0682] • The terminal reports whether it supports NPRACH OCC multiplexing, which means that for Normal RACH procedure, the terminal can perform NPRACH OCC multiplexing, and further, for EDT or non-anchor carrier RACH, based on OCC multiplexing capability indication and non-anchor carrier RACH access and / or EDT capability indication, to further determine whether NPRACH transmission under the corresponding RACH mechanism can be multiplexed by OCC.

[0683] Optional Embodiment 6: Based on optional embodiments 1-3, for single feature-OCC, the terminal that performs OCC multi-user multiplexing performs NPRACH resource selection in the following way:

[0684] - First, based on anchor carrier RSRP measurement and RSRP threshold comparison, determine the CE level

[0685] - If multiple carriers are configured with OCC multiplexing dedicated NPRACH resources under the same CE level, carrier selection is based on the probability parameter configured by the gNB

[0686] - Further, if the current CE level has a dedicated NPRACH resource set corresponding to OCC multiplexing, select this NPRACH resource set; if the current CE level does not have a dedicated NPRACH resource set corresponding to OCC multiplexing, select the Normal NPRACH resource set

[0687] - Finally, the terminal further determines the NPRACH resource set for NPRACH transmission based on its capability and multi-tone / single-tone NPRACH resource configuration

[0688] Optionally, in some embodiments, the OCC configuration related parameters are configured by at least one of the following signaling: SIB2-NB, SIB2-NB

[0689] Optionally, there are the following features: 1. For NPRACH, different OCC length is supported, and different NPRACH resources correspond to different OCC length. The NPRACH resources are divided in different ways.

[0690] 2. The terminal determines the corresponding OCC length by judging the link quality.
