[0081] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0082] 1.RIS.

[0083] RIS is an emerging type of artificial material device. RIS device units can dynamically or semi-statically adjust their electromagnetic properties to influence the reflection or refraction of electromagnetic waves incident on them, causing changes in the electromagnetic parameters (such as phase, amplitude, or polarization) of the forwarded signal (e.g., reflected, transmitted, or refracted). RIS devices are composed of a large number of RIS device units. By controlling the electromagnetic properties of each RIS unit, their reflection or refraction behaviors are spatially superimposed, enabling functions such as beam scanning or beamforming.

[0084] A network containing RIS can use it to serve both near-end and far-end users, thereby improving network coverage. RIS devices can be transparent, meaning that terminals do not need to know whether received or transmitted signals pass through the RIS device or use a specific beam from the RIS device. In this case, the RIS itself must be able to adaptively switch to a specific mode at any time, such as switching mode or using a specific beam transmission mode. A non-transparent RIS is visible to terminals, and requires pre-determined transmission configurations to be used at different times or on different frequency resources.

[0085] The RIS device can include a control module that interacts with the base station via a wireless or wired interface. The RIS can receive control from an upstream base station, meaning the base station can control the RIS's transmission parameters, such as the receive or transmit beams between the RIS and the base station or between the RIS and the UE, to improve RIS efficiency. The network structure shown in Figure 2 includes three network nodes. The intermediate network node is a RIS device that includes a mobile termination module (MT) and a RIS panel. The MT can establish a connection with the upstream base station (e.g., via a control link). The base station transmits control signaling to the RIS via the MT, controlling the transmission or reception parameters between the RIS and the base station (i.e., the backhaul link) or between the RIS and the UE (i.e., the access link).

[0086] Optionally, RIS can be divided into three types: active, passive, and hybrid, depending on whether it has active units.

[0087] Among them, passive means that all units in RIS are passive units; active means that all units in RIS are active units; hybrid means that some units in RIS are passive units and some are active units.

[0088] 2. 5G synchronization signal and physical broadcast channel (PBCH).

[0089] To enable terminals to search for a suitable cell and synchronize with it, network equipment typically broadcasts synchronization signals and provides certain key information about the cell. Synchronization signals primarily include primary synchronization signals and secondary synchronization signals. The PBCH, also known as the Master Information Block, carries the most important system information.

[0090] 3. Mapping rules for the Synchronization Signal and PBCH block (SSB) to the Physical Random Access Channel (PRACH) transmission occasion in 5G NR.

[0091] The PRACH transmission occasion can be referred to as a random access channel occasion (RO). In 5G NR, the PRACH transmission resources and the configuration parameters of SSB-RO are configured in the system information block (SIB) 1. In NR, a cell can configure multiple frequency division multiplexed (FDM) PRACH transmission occasions (physical random access channel transmission opportunities, or PRACH Occasions, abbreviated as RO) at a time domain position for transmitting PRACH. At a time, the number of ROs that can perform FDM can be 1, 2, 4 or 8, which is configured and determined by the high-level parameter msg1-FDM.

[0092] 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. RA ∈{0,1,...,M-1}, where M is equal to the high-level parameter msg1-FDM. At the time of initial access, the PRACH frequency domain resource n RA The PRACH frequency domain resource n is numbered in ascending order starting from the lowest frequency RO resource in the initial active uplink bandwidth part. Otherwise, the PRACH frequency domain resource n isRA The RO resources are numbered in ascending order starting from the lowest frequency resource within the active uplink bandwidth part. For example, in Figure 3, the number of FDM ROs at a time is 8 (msg1-FDM=8), and the RO resources are numbered from RO#0 to RO#7 in ascending order of frequency.

[0093] In NR, there is an association between the RO and the actual SSB transmitted. ROs are associated with SSBs in the frequency domain (e.g., from low frequency to high frequency) and then in the time domain. An SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with one RO. This is configured by the network device using the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB. When multiple SSBs are associated with one RO, different SSBs correspond to different preambles.

[0094] After all SSBs have completed one round of association with the RO, an SSB-RO mapping cycle is formed. An SSB-RO association period may include one or more SSB-RO mapping cycles. An SSB-RO association pattern period may include one or more SSB-RO association periods. The SSB-RO mapping is repeated based on the association pattern period, and the maximum association pattern period is 160ms.

[0095] Optionally, the base station can use different beams to send different SSBs, where the number of SSBs is configured by the ssb-PositionsInBurst parameter. For FR2, the maximum number of SSBs is 64. The UE selects the RO associated with the SSB with a good signal or the associated RO and preamble combination based on the strength of the received downlink beam / SSB, and sends message 1 (Msg1). In this way, the network-side device can determine the SSB selected by the UE based on the RO or RO and preamble combination of the received Preamble. And send Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0096] Taking Figure 3 as an example, the number of FDM ROs at a given moment is 8, and the number of SSBs actually transmitted is 4. That is, each SSB in SSB#0, SSB#1, SSB#2, and SSB#3 is associated with two ROs. If the UE determines to send PRACH or Msg1 on the RO corresponding to SSB#0, the UE selects an RO between RO#0 and RO#1 to send the PRACH.

[0097] Taking Figure 4 below as an example, the number of FDM ROs at a given moment is 2, and the number of SSBs actually transmitted is 8, namely SSB#0, SSB#1, ..., SSB#7, with one RO associated with every two SSBs. When multiple SSBs share a RO, the preamble sets associated with these multiple SSBs are different, that is, the same preamble cannot belong to the preamble sets associated with different SSBs at the same time: Taking RO#0 in Figure 4 as an example, RO#0 has a total of 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.

[0098] In Figure 4, one square is associated with one RO and two SSBs. RO#0 is associated with SSB#0 and SSB#1, RO#1 is associated with SSB#2 and SSB#3, RO#2 is associated with SSB#4 and SSB#5, RO#3 is associated with SSB#6 and SSB#7, RO#4 is associated with SSB#0 and SSB#1, RO#5 is associated with SSB#2 and SSB#3, RO#6 is associated with SSB#4 and SSB#5, and RO#7 is associated with SSB#6 and SSB#7.

[0099] Optionally, before sending PRACH, the UE first selects a received beam (SSB) with a reference signal received power (RSRP) higher than a threshold based on the RSRP of the SSB. If the RSRPs of multiple SSBs are higher than the threshold, the terminal can select any SSB with an RSRP higher than the threshold. When there is no SSB with an RSRP higher than the threshold, the UE selects an SSB based on the implementation.

[0100] Based on the NW configuration, the UE obtains the correspondence between the SSB and the RO. After selecting the SSB, the RO corresponding to the selected SSB is used as the RO for transmitting the PRACH, Preamble, or Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs for transmitting the PRACH, Preamble, or Msg1.

[0101] For example: In the example shown in Figure 3, assuming that the UE selects SSB#1, the UE can select one from RO#2 and RO#3 to send PRACH or Msg1; in the example shown in Figure 4, if the UE selects SSB#1, the UE can select the available RO closest to the current time among the ROs (RO#0 or 4) associated with SSB#1 to send PRACH or Msg1. In the selected RO, the UE selects a preamble from the preamble set associated with the selected SSB to send PRACH. As shown in Figure 4, one RO is associated with two SSBs, so in the available preamble set associated with the SSB in one RO, the preamble will be divided into two subsets, each subset corresponding to one SSB. The UE will select a preamble sequence in the preamble subset corresponding to the selected SSB for sending PRACH or Msg1.

[0102] 4. Random access process.

[0103] Random access can have many purposes. For example, random access triggered by a Physical Downlink Control Channel (PDCCH) order is primarily used to enable the UE to obtain uplink time synchronization. Another example is when the UE establishes an initial radio link, it can obtain user identification information, such as the Cell Radio Network Temporary Identifier (C-RNTI), through the random access process.

[0104] Optionally, the random access procedure may be a contention-based random access procedure or a non-contention-based random access (Contention Free Random Access, CFRA) procedure. The random access procedure may be a four-step random access procedure, also known as a Type-1 random access procedure, or a two-step random access procedure, also known as a Type-2 random access procedure.

[0105] In the contention-based 4-step random access process, the UE first sends msg1, including a preamble, to the network device. After detecting the preamble, the network device sends msg2 or a random access response (RAR) message, including the number of the preamble detected by the network device 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 is consistent with the number of the preamble it sent, and then sends msg3 containing contention resolution information according to the resources indicated by the RAR. After receiving msg3, the network sends msg4 containing contention resolution information. After receiving msg4, the UE confirms that the resolution information is consistent with the one it sent in msg3, thus completing the 4-step random access.

[0106] The network device includes uplink grant (UL grant) information in the RAR to indicate the MSG3 Physical Uplink Shared Channel (PUSCH) scheduling information, and also includes information such as the RACH preamble ID (RAPID), temporary cell RNTI (TC-RNTI), and tracking area (TA). If the network device does not receive the MSG3 PUSCH, it can schedule the retransmission of the MSG3 PUSCH in the PDCCH scrambled by the TC-RNTI.

[0107] For the contention-based random access process, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send on the same time-frequency radio resources (such as RO resources). This situation can be understood as a UE preamble conflict. In this case, different UEs will receive the same RAR. At this time, different UEs will transmit MSG.3PUSCH according to the scheduling information in the RAR UL grant. Since repeated transmission of MSG.3PUSCH is not currently supported, the network-side device can only decode the PUSCH (including contention resolution information) sent by one UE on one MSG3 PUSCH scheduling resource, so the network-side device will include the contention resolution information received in MSG3 in MSG4. If the contention resolution information in MSG4 received by the UE matches the contention resolution information sent by the UE in MSG3 PUSCH, the UE considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.

[0108] If the contention resolution is unsuccessful, the UE reselects RACH transmission resources, performs PRACH transmission, and makes the next random access attempt.

[0109] NR Rel-16 introduced the two-step random access procedure, 2-step RACH. The first step is for the UE to send MsgA to the network. After receiving MsgA, the network sends MsgB to the UE. If the UE does not receive MsgB within a certain period of time, it increments the counter counting the number of MsgA transmissions and resends MsgA. If the MsgA transmission counter reaches a certain threshold, the UE switches from the 2-step random access procedure to the 4-step random access procedure.

[0110] MsgA consists of the MsgA preamble and MsgA PUSCH components. The preamble is sent on the Ro used for 2-step RACH, and the PUSCH is sent on the MsgA PUSCH resources associated with the MsgA preamble and Ro. MsgA PUSCH resources are a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources, and are associated with the PRACH transmission resources within the PRACH slot.

[0111] The non-contention-based random access process triggered by the network side device is as follows:

[0112] 1. Receive random access resource configuration information corresponding to a non-contention-based random access procedure indicated by an NW. The configuration information can be used for beam failure recovery (BFR), handover (HO), or a non-contention-based random access procedure triggered by a PDCCH order. The corresponding configuration information indicates the applicable beam indication and associated non-contention preamble for the non-contention-based random access procedure. For BFR and HO, the corresponding configuration information may also include RO configuration information and a reference signal received power (RSRP) threshold for beam selection.

[0113] 2. After obtaining the configuration information, for BFR and HO, the UE will determine whether to use non-contention random access resources based on the measured beam quality and RSRP threshold. For example, non-contention random access resources will be used only if the beam quality is higher than the RSRP threshold. Subsequently, the UE selects a beam and its corresponding non-contention preamble and sends Msg1 to the network. Msg1 carries the non-contention preamble. After receiving Msg1, the network sends Msg2 to the UE, which carries uplink grant information and the random access preamble ID. If the preamble ID is the same as the random access preamble ID sent by the UE in Msg1, the UE considers the random access process successful and transmits the RAR-scheduled PUSCH. Otherwise, the preamble transmission counter (PREAMBLE_TRANSMISSION_COUNTER) is incremented by one, and a new random access attempt is initiated, random access resources are selected again, and Msg1 is sent.

[0114] 5. Determination of the RO set when PRACH is repeatedly transmitted.

[0115] Currently, PRACH repetition is introduced to enhance uplink coverage. For PRACH repetition, the UE needs to repeatedly send the Preamble on multiple valid ROs at different time domain positions associated with the same SSB. The number of repetitions can be {2, 4, 8}. After the UE determines the number of PRACH repetitions, it needs to determine the RO set. The number of valid ROs in the RO set is equal to the number of PRACH repetitions. Assuming that the number of PRACH repetitions is N1, the RO group determination rule is as follows: within the association period of one or more SSBs to ROs, first determine the starting RO of the RO group, and then determine the remaining N-1 ROs of the RO group. The remaining N1-1 ROs of each RO group are ROs associated with the same SSB, the same frequency position and the same associated Preamble set as the starting RO. Multiple RO groups are determined in the order from low to high in the frequency domain and then in increasing order in the time domain. For the same frequency domain position, the RO group may optionally be configured with an RO-level offset. The determination of the association period of one or more SSBs to a RO group is based on a minimum time window within which at least each SSB can be associated with a RO group. For example, in Figure 5 , assuming the PRACH repetition count is 2, the RO group for SSB #0 can be determined as shown in Figure 5 .

[0116] It should be noted that in each embodiment of the present application, RIS transmission resources or RIS transmission time units or RIS resources or RIS transmission time or RIS transmission frequency units or RIS transmission frequencies, etc., are resources occupied by signals transmitted through RIS, and may also be other specific signal transmission resources, such as signal transmission resources for signal transmission of a specific target object or a group of target objects, or may be transmission signal resources associated with a certain or a certain or a certain group of reference signals, or a certain specific transmission signal resource. Among them, the target object may be a device or node such as a repeater, TRP, tag (TAG), cell, and integrated access backhaul (IAB) signal transmission). A certain or a certain or a certain group of reference signals corresponds to a signal associated with RIS or the other specific signal transmission resource. Among them, the specific transmission signal resource can be understood or replaced by a signal transmission resource forwarded through RIS or for a target object or a specific beam.

[0117] It should be understood that the RIS mentioned in this application can also be generalized to one or a group of repeaters, TRPs, TAGs, cells, IABs, or beams, or can be generalized to signal transmission functions for other specific purposes. The SSB mentioned in this application can refer to any module that includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), or other system message downlink broadcast channels and their control channels.

[0118] The transmission processing method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0119] 6 , an embodiment of the present application provides a transmission processing method. As shown in FIG6 , the transmission processing method includes:

[0120] Step 601: The terminal determines a first resource for a first uplink transmission according to target information;

[0121] Step 602: The terminal sends the first uplink transmission on the first resource;

[0122] The resource type of the first resource includes an intelligent metasurface RIS resource or a non-RIS resource; and the target information includes at least one of the following:

[0123] First information sent by a network-side device, where the first information is used to indicate whether a resource type of the first resource is a RIS resource;

[0124] a second uplink transmission associated with the first uplink transmission;

[0125] downlink transmission associated with the first uplink transmission;

[0126] A random access opportunity RO on the transmission resource of the physical random access channel PRACH.

[0127] In an embodiment of the present application, determining the first resource can be understood or replaced by determining at least one of the resource type of the first resource and the resource location of the first resource. The terminal can determine the first resource of the first uplink transmission based on one or more items in the target information. For example, when the terminal obtains one item of content in the target information, it can determine the first resource based on one of the obtained contents. When multiple items are obtained, the first resource can be determined according to certain rules, such as according to the corresponding priority information, determining to use one of the items to determine the first resource. For example, in some embodiments, the priority of the first information is greater than the priority of the second uplink transmission. In this case, when the first information is not obtained, the first resource can be determined based on the second uplink transmission; when the first information is obtained, the first resource can be determined based on the first information.

[0128] It should be understood that in the embodiments of the present application, the resource type of the first resource includes RIS resources or non-RIS resources. That is, the RIS can be non-transparent to the terminal, and the first uplink transmission can be based on or not based on the RIS. When the first uplink transmission is based on the RIS, the terminal can send the first uplink transmission to the RIS, which can forward it, and the network-side device can receive the first uplink transmission forwarded by the RIS. In this way, the RIS can dynamically open and adjust the RIS transmission direction each time a remote user sends a signal, and even has the function of parsing some control signals. Therefore, the embodiments of the present application can reduce the requirements for the RIS, thereby ensuring improved cell coverage and capacity while maintaining a low-cost RIS.

[0129] In an embodiment of the present application, a terminal determines a first resource for a first uplink transmission based on target information; the terminal sends the first uplink transmission on the first resource; wherein the resource type of the first resource includes a smart metasurface RIS resource or a non-RIS resource; and the target information includes at least one of the following: first information sent by a network-side device, the first information being used to indicate whether the resource type of the first resource is a RIS resource; a second uplink transmission associated with the first uplink transmission; a downlink transmission associated with the first uplink transmission; and a random access opportunity (RO) on a physical random access channel (PRACH) transmission resource. Thus, because the method for determining the first resource for the terminal's first uplink transmission is clarified, the RIS-based transmission of the first uplink transmission can be implemented, thereby improving cell coverage and capacity.

[0130] Optionally, in some embodiments, the first uplink transmission includes at least one of a PRACH, a physical uplink shared channel PUSCH in a random access process, a first reference signal in a random access process, and an RO on a transmission resource of the PRACH.

[0131] Optionally, in some embodiments, when the first uplink transmission includes competitive random access of PRACH, the downlink transmission includes a PDCCH command; when the first uplink transmission includes competitive random access of PRACH, the downlink transmission includes a signal or channel that triggers non-competitive random access.

[0132] In the embodiment of the present application, the target information may include at least one of the first information and downlink transmission. In the case where the PRACH is CFRA, the downlink transmission includes a physical downlink control channel PDCCH command or a signal or channel that triggers non-contention random access.

[0133] Optionally, in some embodiments, the first resource satisfies at least one of the following:

[0134] The resource type of the first resource is configured by a network-side device; for example, the resource type of the first resource is indicated by a PDCCH order.

[0135] The resource type of the first resource is determined based on the resource type of the transmission resource of the downlink transmission;

[0136] In a case where the downlink transmission includes a PDCCH command, the first resource and the transmission resource of the PDCCH command are located in the same RIS resource window or the same non-RIS resource window;

[0137] In a case where the downlink transmission includes a signal or channel triggering non-contention random access, the resource type of the first resource is the same as the resource type of the transmission resource of the signal or channel triggering non-contention random access.

[0138] Optionally, in some embodiments, when the first uplink transmission includes a physical uplink shared channel PUSCH in a random access procedure, the second uplink transmission includes a PRACH.

[0139] Optionally, in some embodiments, whether the MsgA PUSCH is a RIS resource depends on whether the resource type of the PRACH resource associated with it is a RIS resource. For example, if the PRACH resource associated with the MsgA PUSCH is a RIS resource, then the MsgA PUSCH is a RIS resource and the RIS resource is used to transmit the MsgA PUSCH.

[0140] Optionally, in some embodiments, MsgA PRACH resources on RIS resources may be associated with MsgA PUSCH resources on RIS resources and non-RIS resources.

[0141] In some embodiments, the first resource satisfies at least one of the following:

[0142] The resource type of the first resource is configured by a network-side device;

[0143] The resource type of the first resource is determined based on the resource type of the PRACH transmission resource;

[0144] The resource type of the first resource is determined based on the resource type of a transmission resource of a random access response RAR or a transmission resource of a PDCCH corresponding to the first resource;

[0145] The resource type of the first resource is different from the resource type of the PRACH transmission resource.

[0146] Optionally, in some embodiments, when the resource type associated with the PRACH transmission resource includes RIS resources and non-RIS resources, the resource type of the first resource is different from the resource type of the PRACH transmission resource.

[0147] In the embodiment of the present application, the above-mentioned PUSCH may include MsgA PUSCH, Msg3 PUSCH and Msg 5 PUSCH. In some embodiments, the above-mentioned first uplink transmission may also include a normal PUSCH except the PUSCH in the random access process.

[0148] It should be understood that, in the case where the downlink transmission includes a signal or channel that triggers non-contention random access, the transmission resources of the PRACH are only used for RIS transmission or non-RIS transmission.

[0149] Optionally, in some embodiments, when the first uplink transmission includes a first reference signal in a random access procedure, the target information satisfies at least one of the following:

[0150] The second uplink transmission includes a second reference signal associated with the first reference signal;

[0151] The downlink transmission includes a trigger signal for triggering or activating the first reference signal.

[0152] In the embodiment of the present application, the first reference signal may include but is not limited to a sounding reference signal (SRS) and a wake-up signal (WUS).

[0153] Optionally, in some embodiments, the first resource satisfies at least one of the following:

[0154] The resource type of the first resource is configured by a network-side device;

[0155] The resource type of the first resource is determined based on the resource type of the transmission resource of the trigger signal;

[0156] The first resource and the transmission resource of the trigger signal are located in the same RIS resource window or the same non-RIS resource window;

[0157] The resource type of the first resource is determined based on the resource type of the transmission resource of the second reference signal;

[0158] The resource type of the first resource is the same as the resource type of the transmission resource of the trigger signal;

[0159] The trigger signal is used to trigger or activate a first reference signal, and the second reference signal is associated with the first reference signal.

[0160] Optionally, in some embodiments, when the PRACH is a non-contention random access, the target information includes an RO corresponding to the transmission resource of the PRACH, and the RO corresponding to the transmission resource of the PRACH satisfies at least one of the following:

[0161] The RO corresponding to the RIS resource in the PRACH transmission resource and the RO corresponding to the non-RIS resource in the PRACH transmission resource are configured independently, or the RO corresponding to the RIS resource in the PRACH transmission resource and the RO corresponding to the non-RIS resource in the PRACH transmission resource are configured through the same PRACH resource configuration;

[0162] A time domain interval between an RO corresponding to a RIS resource in the PRACH transmission resource and an RO corresponding to a non-RIS resource in the PRACH transmission resource is greater than or equal to a first threshold;

[0163] The frequency domain interval between the RO corresponding to the RIS resource in the PRACH transmission resource and the RO corresponding to the non-RIS resource in the PRACH transmission resource is less than a second threshold;

[0164] The RO corresponding to the RIS resource in the PRACH transmission resource and the preamble code corresponding to the non-RIS resource in the PRACH transmission resource are different.

[0165] In the embodiment of the present application, the first threshold and the second threshold may be agreed upon by a protocol or configured by a network-side device, and are not further limited here.

[0166] In the embodiment of the present application, for the case where the RO corresponding to the RIS resources in the PRACH transmission resources and the RO corresponding to the non-RIS resources in the PRACH transmission resources are independently configured: for the RIS resources, one PRACH configuration is configured, and only the PRACH transmission resources located within the RIS resource window are valid; for the non-RIS resources, one PRACH configuration is configured, and only the PRACH transmission resources located within the non-RIS window are valid.

[0167] Regarding the case where the RO corresponding to the RIS resource in the PRACH transmission resources and the RO corresponding to the non-RIS resource in the PRACH transmission resources are configured using the same PRACH resource configuration: the RO corresponding to the RIS resource and the RO corresponding to the non-RIS resource are configured and determined using the same PRACH resource configuration. For example, using the same PRACH configuration, periodic RO resources are configured, and both the RIS resource window and the non-RIS resource window are configured. The RO located within the RIS resource window is a RIS RO resource, and the RO located within the non-RIS resource window is a non-RIS RO resource.

[0168] By limiting the time domain interval between the RO corresponding to the RIS resource in the PRACH transmission resources and the RO corresponding to the non-RIS resource in the PRACH transmission resources to be greater than or equal to the first threshold, this can prevent the reception time of the RIS RO from overlapping with the time window for PRACH reception on the non-RIS RO, thereby improving transmission reliability. In addition, by limiting the frequency domain interval between the RO corresponding to the RIS resource in the PRACH transmission resources and the RO corresponding to the non-RIS resource in the PRACH transmission resources to be greater than or equal to the second threshold, this can prevent overlap between the RIS RO and the non-RIS RO in the frequency domain, thereby improving transmission reliability.

[0169] The fact that the RO corresponding to the RIS resource in the PRACH transmission resource and the preamble corresponding to the non-RIS resource in the PRACH transmission resource are different can be understood as: the RO corresponding to the RIS resource and the RO corresponding to the non-RIS resource support different preambles.

[0170] Optionally, in some embodiments, the method further comprises:

[0171] The terminal determines a second resource, where the second resource includes repeated transmission for the first uplink transmission.

[0172] Optionally, in some embodiments, the second resource satisfies at least one of the following:

[0173] Some of the second resources in the at least twice repeatedly transmitted second resources are RIS resources, and some of the second resources are non-RIS resources; or all of the second resources are RIS resources or non-RIS resources;

[0174] The second resource is a continuous physical time unit;

[0175] The second resource is a continuously available time unit;

[0176] The second resource is a continuous physical time unit on a RIS resource or a non-RIS resource;

[0177] The second resource is a continuously available time unit on a RIS resource or a non-RIS resource;

[0178] The resource type of the second resource is configured by the network side device;

[0179] The resource type of the second resource is determined based on a resource type of a transmission resource of an RAR or a transmission resource of a PDCCH corresponding to the second resource.

[0180] Optionally, the granularity of the above time unit can be set according to actual needs. For example, in some embodiments, the above time unit can be a time slot, a sub-time slot, a frame, a subframe, a millisecond or a time period configured by the network side device.

[0181] Optionally, in some embodiments, the network-side device may indicate the resource type of the second resource, or indicate whether the second resource is a RIS resource, through the RAR or downlink control information (DCI) that schedules the RAR.

[0182] In some embodiments, the network side device can control whether the second resource is a RIS resource through the time domain resource allocation (TDRA) or frequency domain resource allocation (FDRA) field, for example, indicating the resource type in the TDRA field or indicating the corresponding resource type in the TDRA table indicated by the TDRA field.

[0183] In some embodiments, different TDRA tables are defined for different resource types, and the network-side device specifies which table to use.

[0184] In some embodiments, the terminal determining the second resource includes:

[0185] The terminal determines the second resource based on a resource window, where the resource window is determined based on at least one of the following:

[0186] RIS resource allocation cycle;

[0187] The frequency band of the RIS resource configuration or the frequency domain transmission opportunity of the RIS resource configuration.

[0188] Optionally, in some embodiments, the method further comprises:

[0189] The terminal determines a third resource, where the third resource includes a retransmission for the first uplink transmission.

[0190] Optionally, in some embodiments, the third resource satisfies at least one of the following:

[0191] Some of the third resources retransmitted at least twice are RIS resources, and some are non-RIS resources; or, all of the third resources are RIS resources or non-RIS resources, and the resource type of the third resources is the same as the resource type of the first resources;

[0192] The resource type of the third resource is configured by the network side device;

[0193] The resource type of the third resource is determined based on the resource type of the RAR transmission resource or the PDCCH transmission resource corresponding to the third resource;

[0194] The third resource is a continuous physical time unit;

[0195] The third resource is a continuously available time unit;

[0196] The third resource is a continuous physical time unit on a RIS resource or a non-RIS resource;

[0197] The third resource is a continuously available time unit on a RIS resource or a non-RIS resource.

[0198] Optionally, in some embodiments, when the first uplink transmission includes PRACH, the method further includes:

[0199] The terminal determines a backoff time, where the backoff time is used to determine a retransmission time of the PRACH, wherein the backoff time satisfies at least one of the following:

[0200] The start time of the backoff time is the start time of the time unit where the nearest RIS resource is located after the end time of the receiving window corresponding to the PRACH;

[0201] The start time of the backoff time is the start time of the time unit where the nearest non-RIS resource is located after the end time of the receiving window corresponding to the PRACH;

[0202] The length of the backoff time is less than or equal to the target time window;

[0203] The fallback time is determined based on the RIS resource configuration cycle;

[0204] The fallback time indicates the length of a time unit occupied by RIS resources or the fallback time indicates the length of a time unit occupied by non-RIS resources.

[0205] In the embodiment of the present application, the fallback time is determined based on the RIS resource configuration period, which can be understood as the fallback time being the RIS resource configuration period, or being a function of the RIS resource period, for example, an integer multiple of the RIS period.

[0206] Optionally, in some embodiments, when the resource type of the same time-frequency resource includes RIS resources and non-RIS resources, the second information associated with the RIS resources of the time-frequency resource and the second information associated with the non-RIS resources are different, wherein the second information includes at least one of the following: Quasi co-location (QCL); Transmission Configuration Indicator (TCI); a second reference signal.

[0207] In order to better understand the present application, some examples are provided below for illustration.

[0208] Example 1: Determination of PRACH resources during random access.

[0209] For non-transparent RIS, PRACH resources forwarded via RIS and those not forwarded via RIS need to be configured independently or in different time or frequency units within the same configuration. This requires consideration of how to determine the appropriate RO group for PRACH retransmissions, whether forwarded via RIS or not.

[0210] In some embodiments, the determination of the RO for supporting PRACH retransmissions forwarded via the RIS depends on at least one of the following:

[0211] The PRACH retransmission resources are partly non-RIS resources and partly RIS resources;

[0212] PRACH retransmission resources are either all RIS resources or all non-RIS resources;

[0213] The resource window used to determine the RO is determined based on at least one of a RIS resource period, a frequency band configured by the RIS resource, and a frequency domain transmission opportunity.

[0214] It should be understood that non-RIS resources can be understood or replaced by uplink transmission resources forwarded by non-RIS, such as PRACH resources forwarded by non-RIS, and RIS resources can be understood or replaced by uplink transmission resources forwarded by RIS, such as PRACH resources forwarded by RIS. The above-mentioned PRACH resources can be understood or replaced by PRACH transmission resources.

[0215] In the case where the resource window is based on the RIS resource configuration cycle, the following situations may occur:

[0216] For example, when the configuration period of the uplink resources forwarded by the RIS is two association mode periods, the uplink resources in the first association mode period are uplink transmission resources forwarded by the RIS, and the uplink resources in the second association mode period are uplink transmission resources not forwarded by the RIS. The association mode period can be understood as the association mode period of the downlink reference signal to the RO, and the downlink reference signal can be an SSB.

[0217] For another example, when the configuration period of the uplink resources forwarded by the RIS is one association mode period, the uplink resources in the even configuration period are uplink transmission resources forwarded by the RIS, and the uplink resources in the odd configuration period are uplink transmission resources not forwarded by the RIS.

[0218] For another example, when the resource window is a minimum integer multiple of a specific time window, such that for all SSB indices, at least one associated RO group can be determined for PRACH repeated transmission within the minimum integer multiple of the specific time window, where the specific time window is determined by at least the RIS resource configuration period.

[0219] In the case where the resource window is determined by the frequency band configured by the RIS resource, when the number of configured frequency bands for uplink resources is 2, the uplink resources in the first frequency band are uplink transmission resources forwarded by RIS, and the uplink resources in the second frequency band are uplink transmission resources not forwarded through RIS.

[0220] In the case where the above-mentioned resource window is determined by the frequency domain transmission opportunity configured by RIS resources, when the number of configured frequency domain transmission opportunities for the uplink resources is 2, the uplink resources within the first frequency domain transmission opportunity are uplink transmission resources forwarded by RIS, and the uplink resources within the second frequency domain transmission opportunity are uplink transmission resources not forwarded through RIS.

[0221] In some embodiments, PRACH retransmissions forwarded via a RIS are supported, and determination of a RO for the PRACH retransmissions depends on at least one of the following:

[0222] The PRACH multiple retransmission resources are partly non-RIS resources and partly RIS resources;

[0223] The PRACH resources of all PRACH retransmissions are either all RIS resources or all non-RIS resources.

[0224] In the case where all PRACH retransmission resources are either RIS resources or non-RIS resources, only the initial transmission PRACH resources need to determine whether the corresponding PRACH resources are PRACH resources forwarded via RIS. Retransmissions and initial transmissions use the same type of PRACH resources.

[0225] In some embodiments, PRACH retransmissions on PRACH resources forwarded via a RIS are supported, and a backoff time for determining the PRACH retransmission time is determined based on at least one of the following:

[0226] The starting point is the most recent time at which the transmission signal resource forwarded by the RIS is received by the RAR receiving window corresponding to the current PRACH, for example, the most recent symbol or time slot or the starting position of a certain time unit;

[0227] The starting point is the most recent time of the transmission signal resource forwarded by the RIS after the RAR receiving window corresponding to the current PRACH receives it, for example, the starting position of the most recent symbol or slot or a time unit;

[0228] The fallback time must not exceed the target time window, which can be agreed upon by the protocol or configured by the network device.

[0229] The fallback time is a configuration period of the signal resource forwarded via the RIS or a function thereof, for example, an integer multiple of the configuration period of the signal resource forwarded via the RIS;

[0230] For retransmissions of PRACH transmissions forwarded via RIS, the backoff time only considers the time resource of the signal resource forwarded via RIS. For example, if the backoff time is 10ms, this 10ms means that after the RAR window corresponding to the current PRACH transmission ends, PRACH retransmission can only be performed after the RIS time resource exceeds 10ms.

[0231] The back-off time for repeated transmission of a PRACH transmission forwarded via non-RIS only considers the time resource where the signal resource forwarded via non-RIS is located.

[0232] Optionally, for PDCCH ordered PRACH transmissions, whether the PRACH resources used are RIS resources or non-RIS resources needs to be determined. For example, in some embodiments, PRACH resource transmissions on both RIS resources and non-RIS resources are supported, and the determination of the PRACH transmission resources for PDCCH ordered transmissions depends on at least one of the following:

[0233] Whether the PRACH resource is a RIS resource is configured by the network side device, for example, through a PDCCH order indication;

[0234] Whether a PRACH resource is a RIS resource depends on whether the downlink PDCCH order is a downlink RIS resource. That is, whether a PRACH resource is a RIS resource depends on whether it is a PDCCH forwarded via RIS.

[0235] The PDCCH order resources and PRACH transmission resources must be within the same RIS resource window or non-RIS resource window. For example, if the network-side device configures a fixed time window of 10ms, with every even-numbered 10ms as downlink resources corresponding to RIS and every odd-numbered 10ms as downlink resources corresponding to non-RIS, the uplink 10ms corresponding to the PDCCH order triggering the PRACH transmission resources will be the uplink 10ms corresponding to the downlink 10ms corresponding to the PDCCH order.

[0236] Optionally, for CFRA triggered by a network device, the network device may independently configure an RO for PRACH transmission. Consideration should be given to how to configure RIS ROs and non-RIS ROs. For example, in some embodiments, CFRA supports PRACH transmission resources on RIS resources and / or non-RIS resources through at least one of the following:

[0237] RO on RIS resources and RO on non-RIS resources are configured independently. For example, for RIS resources, if a PRACH configuration is configured, only the PRACH resources within the RIS resource window are valid. For non-RIS resources, if a PRACH configuration is configured, only the PRACH resources within the non-RIS resource window are valid.

[0238] RO on RIS resources and RO on non-RIS resources are configured and determined through the same PRACH resource configuration. For example, through the same PRACH configuration, periodic RO resources are configured, and RIS resource windows and non-RIS resource windows are configured at the same time. The RO located in the RIS resource window is a RIS RO resource, and the RO located in the non-RIS resource window is a non-RIS RO resource.

[0239] The time domain interval or frequency domain interval between the RO on the RIS resource and the RO on the non-RIS resource is not less than a certain threshold. The threshold is determined by the network side device or specified by the protocol.

[0240] The preambles supported by ROs on RIS resources are different from those supported by ROs on non-RIS resources.

[0241] Only one type of RO resource is supported: either an RO resource on a RIS resource or an RO resource on a non-RIS resource. In this case, whether the PRACH resource is a RIS resource can be configured by the network device, for example, through a message or signal that triggers CFRA. Alternatively, whether the PRACH resource is a RIS resource depends on whether the resource containing the signal or channel that triggers CFRA is a downlink RIS resource, that is, whether the trigger signal or channel is forwarded via RIS.

[0242] On the other hand, whether PRACH transmission signals are forwarded via the RIS is dynamically controlled by the network. In this case, the terminal does not need to distinguish between RIS and non-RIS resources on uplink resources. For example, in some embodiments, before the PRACH transmission signal is transmitted, the network-side device controls whether the PRACH signal on the corresponding RO is forwarded via the RIS, and what spatial filter or beam is used for RIS forwarding. For example, the network-side device pre-configures PRACH resources, and whether each RO resource is forwarded via the RIS is triggered by the network before the RO through instructions to the RIS device to disable RIS forwarding, enable forwarding, or enable PRACH forwarding on the RO using certain configuration parameters.

[0243] Embodiment 2: Determination of PUSCH resources during random access.

[0244] For non-transparent RIS, PUSCH resources forwarded via RIS and those not forwarded via RIS need to be in corresponding time or frequency units. This requires consideration of how to determine the corresponding PUSCH resources for single or repeated PUSCH transmissions or periodic MsgA PUSCH transmissions scheduled by network-side devices, for both forwarding via RIS and not forwarding via RIS.

[0245] For RAR or DCI scheduled PUSCH transmissions of Msg3 or Msg5, it is necessary to determine whether the PUSCH resources used are RIS resources or non-RIS resources. For example, in some embodiments, PUSCH transmissions on both RIS and non-RIS resources are supported. The determination of PUSCH transmission resources for network dynamic scheduling depends on at least one of the following:

[0246] Whether a PUSCH resource is a RIS resource is configured by the network side device, for example, through an RAR or DCI indication that schedules the RAR, or through the TDRA or FDRA field in the RAR or DCI, or by defining different TDRA tables for different resource types. The network side device specifies which table to use;

[0247] Whether a PUSCH resource is a RIS resource depends on whether the corresponding downlink RAR or PDCCH resource is a downlink RIS resource; that is, whether it is a RAR or PDCCH forwarded via RIS;

[0248] RAR or PDCCH resources and PUSCH transmission resources are required to be in the same RIS or non-RIS resource window.

[0249] For example, if the network-side device configures a fixed time window of 10ms, with every even-numbered 10ms as the downlink resource corresponding to the RIS and every odd-numbered 10ms as the downlink resource corresponding to the non-RIS, then the uplink 10ms where the RAR-scheduled PUSCH transmission resource is located is the uplink 10ms corresponding to the downlink 10ms where the RAR is located.

[0250] For MsgA PUSCH, Msg3 PUSCH, Msg 5 PUSCH or normal PUSCH, when repeated transmission is performed, the determination of the corresponding resources also needs to determine whether two types of resources are allowed. For example, in some embodiments, repeated transmission of PUSCH forwarded via RIS is supported, and the determination of multiple PUSCH transmission resources for the repeated transmission of PUSCH depends on at least one of the following:

[0251] The PUSCH retransmission resources are partly non-RIS resources and partly RIS resources;

[0252] All PUSCH resources for repeated PUSCH transmissions are either all RIS resources or all non-RIS resources;

[0253] The PUSCH retransmission window is determined based on at least one of the RIS resource period, the frequency band of the RIS resource configuration, and the frequency domain transmission opportunity;

[0254] PUSCH repetitive transmission resources are continuous physical time units, such as time slots;

[0255] PUSCH retransmission resources are continuous available time units;

[0256] The PUSCH repetitive transmission resource is a continuous physical time unit on a resource, such as a linked physical time unit on a RIS resource or a linked physical time unit on a non-resource;

[0257] PUSCH repetition transmission resources are continuous available time units on a resource;

[0258] Whether the PUSCH retransmission resource is a RIS resource is configured by the network, for example, through an RAR or DCI indication that schedules the RAR, or through the TDRA or FDRA field in the RAR or DCI, or by defining different TDRA tables for different resource types. The network-side device specifies which table to use;

[0259] Whether the PUSCH retransmission resource is a RIS resource depends on whether the corresponding downlink RAR or PDCCH resource is a downlink RIS resource, that is, whether it is a RAR or PDCCH forwarded via RIS;

[0260] When the window for repeated PUSCH transmission is based on the RIS resource configuration period, the following situations may occur:

[0261] For example, when the configuration period of the uplink resources forwarded by the RIS is two association mode periods, the uplink resources in the first association mode period are uplink transmission resources forwarded by the RIS, and the uplink resources in the second association mode period are uplink transmission resources not forwarded by the RIS. The association mode period can be understood as the association mode period of the downlink reference signal to the RO, and the downlink reference signal can be an SSB.

[0262] For another example, when the configuration period of the uplink resources forwarded by the RIS is one association mode period, the uplink resources in the even configuration period are uplink transmission resources forwarded by the RIS, and the uplink resources in the odd configuration period are uplink transmission resources not forwarded by the RIS.

[0263] For another example, when the PUSCH retransmission window is a minimum integer multiple of a specific time window, it is satisfied that for all SSB indices, at least one associated RO group can be determined for PRACH retransmission within the minimum integer multiple of the specific time window. The specific time window is determined by at least the RIS resource configuration period.

[0264] When the PUSCH retransmission window is determined based on the frequency band configured by the RIS resource, if the number of configured frequency bands for uplink resources is 2, the uplink resources in the first frequency band are uplink transmission resources forwarded by the RIS, and the uplink resources in the second frequency band are uplink transmission resources not forwarded by the RIS.

[0265] Optionally, in some embodiments, PUSCH retransmission forwarded via RIS is supported, and determination of PUSCH resources for the PUSCH retransmission depends on at least one of the following:

[0266] The PUSCH multiple retransmission resources are partly non-RIS resources and partly RIS resources;

[0267] All PUSCH retransmission PUSCH resource groups are either all RIS resources or all non-RIS resources. In this case, only the initial transmission PUSCH resources need to determine whether the corresponding PUSCH resources are PUSCH resources forwarded via RIS. Retransmission and initial transmission use the same type of PUSCH resources.

[0268] Whether the PUSCH retransmission resource is a RIS resource is configured by the network side device; for example, through the RAR or DCI indication of scheduling RAR, or through the TDRA or FDRA field in the RAR or DCI, or by defining different TDRA tables for different resource types. The network side device specifies which table to use;

[0269] Whether the PUSCH retransmission resource is a RIS resource depends on whether the corresponding downlink RAR or PDCCH resource is a downlink RIS resource, that is, whether it is a RAR or PDCCH forwarded via RIS.

[0270] Optionally, for MsgA PUSCH, whether its transmission is a RIS resource may depend on the type of PRACH resource. For example, in some embodiments, whether the MsgA PUSCH is a RIS resource depends on whether its associated PRACH resource is a RIS resource.

[0271] Sometimes, a PRACH resource on a RIS or non-RIS resource may need to be associated with PUSCH resources of two resource types, especially when the PRACH resource is far away from the PUSCH resource it is associated with.

[0272] In some embodiments, the MsgA PRACH resources on the RIS resources can be associated with the MsgA PUSCH resources on the RIS resources and non-RIS resources. In this way, after sending the MsgA PRACH, the terminal can decide to switch to another type of resource to send the MsgA PUSCH.

[0273] On the other hand, similar to PRACH, whether the PUSCH signal transmitted by the terminal is forwarded via RIS is dynamically controlled by the network-side device. In this case, the terminal does not need to distinguish between RIS and non-RIS resources on the uplink resources. In some embodiments, before transmitting the PUSCH signal, the network-side device controls whether the PUSCH signal transmitted on the corresponding PUSCH resource is forwarded via RIS, and what spatial filter or beam is used for RIS forwarding. For example, the network-side device dynamically configures PUSCH resources or MsgA PUSCH resources. Whether the signal transmission on this resource is forwarded via RIS is triggered by the network through instructions before the resource is used to trigger the RIS device to disable RIS forwarding, enable forwarding, or enable forwarding using certain configuration parameters.

[0274] Embodiment 3: Determination of a first reference signal resource.

[0275] Similar to PRACH signal transmission, for non-transparent RIS, the primary reference signal resources forwarded via the RIS, such as SRS or WUS resources, and the primary reference signal resources not forwarded via the RIS need to be configured independently or in different time or frequency units within the same configuration. This requires consideration of how to determine the appropriate RO group for the scenarios of forwarding via the RIS and not forwarding the primary reference signal when the primary reference signal is repeatedly transmitted.

[0276] In some embodiments, repeated transmission of a first reference signal forwarded via a RIS is supported, and determination of a resource for repeated transmission of the first reference signal depends on at least one of the following:

[0277] The repeated transmission resources of the first reference signal are partly non-RIS resources and partly RIS resources;

[0278] All repeated transmission resources of the first reference signal are either all RIS resources or all non-RIS resources;

[0279] The resource window for determining the RO for repeated transmission of the first reference signal is determined based on at least one of a RIS resource period, a frequency band of RIS resource configuration, and a frequency domain transmission opportunity.

[0280] In the case where the resource window is based on the RIS resource configuration cycle, the following situations may occur:

[0281] When the configuration period of the uplink resources forwarded by the RIS is 2 association mode periods, the transmission resources of the first reference signal in the first association mode period are the transmission resources of the first reference signal forwarded by the RIS, and the transmission resources of the first reference signal in the second association mode period are the transmission resources of the first reference signal not forwarded by the RIS.

[0282] When the configuration period of the uplink resources forwarded by the RIS is 1 association mode period, the first reference signal transmission resources in the even configuration period are the transmission resources of the first reference signal forwarded by the RIS, and the first reference signal transmission resources in the odd configuration period are the transmission resources of the first reference signal not forwarded through the RIS.

[0283] When the resource window is the minimum integer multiple of a specific time window, it satisfies that for all SSB indices, at least one associated RO group can be determined within the minimum integer multiple of this specific time window for PRACH repeated transmission. The specific time window is determined based on at least one of the following: RIS resource configuration period, association period of other reference signals to the first reference signal, association pattern period of other reference signals to the first reference signal, mapping period of other reference signals to RO, association period of other reference signals to RO, association pattern period of other reference signals to RO, mapping period of first reference signal to RO, association period of first reference signal to RO, association pattern period of first reference signal to RO, configuration period of first reference signal, and PRACH configuration period. Other reference signals can be understood as reference signals other than the first reference signal.

[0284] In some embodiments, retransmission of a first reference signal forwarded via a RIS is supported, and determination of resources for retransmission of the first reference signal depends on at least one of the following:

[0285] The multiple retransmission resources of the first reference signal are partially non-RIS resources and partially RIS resources;

[0286] All first reference signal retransmission resources are either all RIS resources or all non-RIS resources. In this case, only the first reference signal initial transmission resources need to determine whether the corresponding first reference signal resources are first reference signal resources forwarded and transmitted via RIS. Retransmissions and initial transmissions use the same type of first reference signal resources.

[0287] Optionally, for first reference signal transmission, whether the first reference signal resource used is a RIS resource or a non-RIS resource needs to be determined. For example, in some embodiments, first reference signal resource transmission on both RIS resources and non-RIS resources is supported, and the determination of the first reference signal transmission resource depends on at least one of the following:

[0288] Whether the first reference signal resource is a RIS resource is configured by the network side device; for example, indicated by signaling that triggers the sending of the first reference signal or indicated in signaling that configures the first reference signal resource;

[0289] Whether the first reference signal resource is a RIS resource depends on whether the signal that triggers or activates the transmission of the first reference signal is a RIS resource, that is, whether it is a trigger signal forwarded via RIS. For example, the trigger signal transmission resource that triggers the transmission of the first reference signal and the resource where the triggered first signal transmission is located must be within the same RIS or non-RIS resource window. For example, if the network-side device is configured with a fixed time window of 10ms, with every even-numbered 10ms as a downlink resource corresponding to RIS and every odd-numbered 10ms as a downlink resource corresponding to non-RIS, then the trigger signal transmission resource and the first signal transmission resource must be within the same 10ms.

[0290] Whether the first reference signal resource is a RIS resource depends on whether the second signal associated with the first reference signal transmission is a RIS resource. For example, by introducing the association between the second reference signal and the first reference signal, for a certain first reference signal transmission opportunity, if its associated second reference signal is forwarded via RIS, then the transmission of the first reference signal at the first reference signal resource transmission opportunity is also RIS forwarding.

[0291] On the other hand, similar to PRACH, whether the first reference signal is forwarded via the RIS is dynamically controlled by the network-side equipment. In this case, the terminal does not need to distinguish between RIS and non-RIS resources on uplink resources. In some embodiments, before sending the first reference signal, the network controls whether the first reference signal on the corresponding resource is forwarded via the RIS and what spatial filter or beam is used for RIS forwarding.

[0292] For example, the network side device pre-configures the first reference signal resource. Whether each first reference signal transmission is forwarded through RIS is determined by the network side device before the first reference signal transmission opportunity by instructing the RIS device to turn off RIS and not forward it, turn on RIS for forwarding, or turn on and use certain configuration parameters to forward the first reference signal at the first reference signal transmission opportunity.

[0293] Embodiment 4: RIS or non-RIS transmission on the same time-frequency resource.

[0294] The same time-frequency resource may include multiple transmission resources, such as PRACH transmission or other transmissions, such as PUSCH, Msg3, Msg5, SRS, WUS and PUCCH, and the multiple transmission resources may be different types of transmission resources. For example, the multiple transmission resources include RIS resources and non-RIS resources. In this case, the UE needs to transmit according to different QCL assumptions or different TCIs.

[0295] For example, in some embodiments, RIS resource and non-RIS resource transmission on the same time-frequency resource is supported. Optionally, the RIS resource transmission and non-RIS resource transmission on the same time-frequency resource use different QCL assumptions or TCI transmissions, or are associated with different reference signals.

[0364] 8 , an embodiment of the present application further provides a transmission processing method. As shown in FIG8 , the transmission processing method includes:

[0365] In step 801, a network-side device sends target indication information to the intelligent metasurface RIS, where the target indication information is used to determine whether a first uplink transmission of a terminal is to be transmitted based on the RIS.

[0366] In an embodiment of the present application, before a terminal sends a first uplink transmission, a network-side device can dynamically control the RIS using target indication information. Upon receiving the target indication information, the RIS can, based on the target indication information, disable the RIS and not forward the first uplink transmission; enable the RIS to forward the transmission; or enable the RIS to forward the transmission using certain configuration parameters. This makes the RIS transparent to the terminal, eliminating the need for the terminal to distinguish between RIS and non-RIS resources in uplink resources, thereby reducing the complexity of resource configuration. Furthermore, the RIS-based first uplink transmission can be sent, improving cell coverage and capacity.
