[0004] For networks that include Reconfigurable Intelligent Surfaces (RIS), signals can communicate with remote users through the RIS or with near-end users without going through the RIS.

[0066] In order to better understand the technical solutions of the embodiments of the present application, the relevant concepts and principles involved in the embodiments of the present application are briefly described below.

[0067] Reconfigurable Intelligent Surfaces (RIS):

[0068] 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 (phase, amplitude, or polarization) of the forwarded signal (reflected signal or transmitted / refracted signal). 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 and beamforming.

[0069] A network containing a RIS can serve both near-end and far-end users without using the RIS, thereby improving network coverage. The RIS device can be transparent, meaning that the terminal does not need to know whether the received or transmitted signal passes through the RIS device or uses a specific beam of the RIS device. In this case, the RIS itself needs to be able to adaptively switch to the corresponding mode at any time, such as on / off mode or using a specific beam transmission mode. A non-transparent RIS, in which the RIS is visible to the terminal, requires pre-determining the specific transmission configuration that the RIS will use at different times or on different frequency resources. This means determining which beam the RIS will use to transmit signals at which times, or which frequency locations the RIS will use to transmit signals at which beams. For example, in Figure 1b, the RIS forwards the base station's downlink signal using beam 1 at time 1, beam 2 at time 2, and beam 3 at time 3.

[0070] 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 (donor), meaning the base station can control the RIS's transmission parameters, such as the receive / transmit beams between the RIS and the base station or between the RIS and the user equipment (UE), to improve RIS efficiency. The network structure shown in Figure 1c 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 (via a control link). The base station transmits control signaling to the RIS via the MT, controlling the transmit / receive parameters between the RIS and the base station (via a backhaul link (BH)) or between the RIS and the UE (via an access link (AL)).

[0071] 5th generation (5 th 5G (5th Generation) communication system synchronization signal and physical broadcast channel (PBCH):

[0072] To enable the UE to search for a suitable cell and synchronize with it, the network typically broadcasts synchronization signals and provides certain key information about the cell. Synchronization signals primarily include the primary synchronization signal and the secondary synchronization signal. The PBCH, also known as the Master Information Block (MIB), carries the most important system information.

[0073] In 5G NR, the configuration parameters of the physical random access channel (PRACH) resources and the synchronization signal block (SSB)-random access channel occasion (RO) are configured in the system information block 1 (SIB1). In NR, a cell can configure multiple frequency division multiplex (FDM) physical random access channel transmission opportunities (PRACH transmission occasion, or PRACH Occasion, abbreviated as RO) at a time domain position for transmitting PRACH. The number of ROs that can perform FDM at a time is determined by the high-level parameter msg1-FDM. At the time of initial access, the PRACH frequency domain resources n_RA are numbered in ascending order starting from the RO resource with the lowest frequency. For example, in Figure 1d, the number of ROs for FDM at a time is 8 (msg1-FDM=8), and the RO resources are numbered RO#0 to RO#7 from low to high frequency.

[0074] In NR, there is an association between the RO and the actual SSB transmitted. ROs are associated with SSBs in the frequency domain (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 a single RO (in this case, different SSBs correspond to different preambles). This is configured by the network using the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB.

[0075] Typically, the base station can use different beams to send different SSBs, where the number of SSBs is configured by the ssb-PositionsInBurst parameter. For the frequency range (FR2), the maximum number of SSBs is 64. The UE selects the RO / "RO and preamble combination" associated with the SSB with a good signal based on the strength of the received downlink beam / SSB, and sends message 1 (Msg1). In this way, the network can determine the SSB selected by the UE based on the RO / "RO and preamble combination" of the received preamble. Message 2 (Msg2) is sent on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0076] Taking Figure 1e as an example, the number of FDM ROs at a time 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 the 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 1e as an example, RO#0 has a total of 60 preambles, of which preambles with indexes 0 to 29 are associated with SSB#0, and preambles with indexes 30 to 59 are associated with SSB#1. It should be noted that each square in Figure 1e is an RO, not an SSB, and the marked SSB refers to which SSB(s) this RO is associated with.

[0077] Before sending PRACH, the UE first selects an SSB with RSRP higher than the threshold based on the received beam (SSB)'s reference signal received power (RSRP); if the RSRP of multiple SSBs is higher than the threshold, the terminal can select any SSB with RSRP higher than the threshold; when there is no SSB with RSRP higher than the threshold, the UE selects an SSB based on the implementation. Based on the network (NW) configuration, the UE obtains the correspondence between SSB and RO. After selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / Preamble / Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs to send PRACH / Preamble / Msg1.

[0078] NR random access process:

[0079] In related NR technologies, the random access procedure can be either a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure can be either a four-step random access procedure (also called a Type-1 random access procedure) or a two-step random access procedure (also called a Type-2 random access procedure).

[0080] In the contention-based four-step random access (RACH) process, the UE first sends Msg1, containing a preamble, to the network. After the network detects the preamble, it sends Msg2 / Random Access Response (RAR), which contains the preamble ID detected by the network and the uplink radio resources allocated to the UE for sending Msg3. The UE monitors the Physical Downlink Control Channel (PDCCH) within a time window (RAR window) to receive Msg2. If the UE confirms that at least one of the preamble IDs carried in Msg2 matches the preamble ID it sent, it sends Msg3 containing contention resolution information based on the resources indicated by the RAR. After receiving Msg3, the network sends Msg4 containing contention resolution information. Upon receiving Msg4, the UE confirms that the resolution information matches the one it sent in Msg3, completing the four-step random access process.

[0081] In NR Rel-16, the two-step random access procedure (2-step RACH) was introduced. The first step is that the UE sends message A (MsgA) to the network side. After receiving MsgA, the network side sends message B (MsgB) to the UE. The UE also needs to monitor the PDCCH within the RAR window to receive MsgB. If the UE does not receive MsgB within a certain period of time, the UE will increment the counter that counts the number of times MsgA has been sent and resend MsgA. If the counter that counts the number of times MsgA has been sent reaches a certain threshold, the UE will switch from the 2-step random access procedure to the four-step (4-step) random access procedure.

[0082] Time domain resource location of downlink signals in NR:

[0083] In NR, the time-domain monitoring position of the PDCCH and the time-domain transmission position of the Tracking Reference Signal (TRS) / Positioning Reference Signal (PRS) are configured using a period and an offset within the period. Taking PDCCH as an example, as shown in Figure 1f, assuming a PDCCH monitoring period of 10 slots and a slot offset of 5, the terminal will monitor the PDCCH in the fifth slot within the monitoring period, as shown by the shaded area in Figure 1f.

[0084] In NR, the timeslot location of the physical downlink shared channel (PDSCH) is determined by the timeslot where the PDCCH is located and the offset value K0 from the timeslot where the PDCCH is located. For example, K0 = 0 means that the PDSCH is located in the timeslot where the PDCCH is located, and K0 = 1 means that the PDSCH is located in the timeslot after the PDCCH.

[0085] In the related art, for networks containing RIS, signals can communicate with remote users through the RIS or with local users without passing through the RIS. When the RIS is in transparent mode, meaning it is invisible to the terminal, whether signals are sent through the RIS resources is not affected by the protocol. However, this increases the requirements for the RIS itself. The RIS needs to be able to dynamically open and adjust the RIS transmission direction every time a remote user sends a signal, and may even need to be able to parse some control signals. In this case, the RIS functionality is similar to that of Integrated Access and Backhaul (IAB), and the cost is high. Therefore, to control RIS costs and simplify RIS functionality, it is necessary to use a non-transparent RIS. This means that the RIS is visible to the terminal and that it must be pre-determined that the RIS will use different transmission configurations at different times, that is, the RIS's signal forwarding behavior at different times and frequencies.

[0086] When RIS is in non-transparent mode, the terminal needs to determine at different times whether RIS will forward signals, as well as which frequency resource locations and in which directions the RIS will send signals at different times. However, it is currently unclear when RIS will forward signals, and which frequency resource locations and in which directions the RIS will send signals at different times.

[0087] An embodiment of the present application proposes a method for determining resource information.

[0088] It should be noted that the RIS transmission resources or RIS transmission time units or RIS resources or RIS transmission time or RIS transmission frequency units or RIS transmission frequencies involved in the embodiments of the present application are resources occupied by signals transmitted through RIS (i.e., at what time and at what frequency RIS will be forwarded, and the corresponding RIS forwarding behavior, such as forwarding to different beams), and may also be other specific signal transmission resources, such as a specific repeater or a group of repeaters / TRPs / timing advance groups (TAGs) / cells (such as non-terrestrial networks (NTNs), small cells) / IABs / beams; or they 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. The certain or a certain or a certain group of reference signals here corresponds to signals associated with RIS / non-RIS / or other specific signal transmission resources. The specific transmission signal resources here may be specifically for signals transmitted through RIS or, for example, a specific or a certain group of repeaters / TRPs / TAGs / cells / IABs. RIS itself is not necessarily reflected in the protocol, or it can be understood that RIS is an example of specific signal transmission.

[0089] The RIS described in the embodiments of the present application can also be broadly extended to one or a group of repeaters / TRPs / TAGs / cells (such as NTN, small cells) / IABs / beams, or signal transmission for other specific purposes.

[0090] The "different RIS sending resource information" involved in the embodiments of the present application may correspond to different beams forwarded by RIS, or may correspond to: different repeater forwarding behaviors (for example, turning on / off / adjusting the power amplification gain of the repeater), or different TRP forwarding, or different TAG forwarding, or different cells (macro base station (macro) / femto base station (femto), terrestrial network (TN) / NTN) sending, etc. At this time, it may not be called "different RIS sending resources", but different repeater / TRP / TAG / cell (such as NTN, small cell) / IAB / beam) sending / forwarding.

[0091] The SSB described in the embodiments of the present application can also be called any module that includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), other system message downlink broadcast channels and their control channels.

[0092] In addition, the RAR or RAR PDSCH described in the embodiment of the present application includes but is not limited to a response signal of the network sending a first signal to the terminal, and the first signal includes but is not limited to Msg1 preamble, MsgA preamble, MsgA physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), random access channel (Random Access Channel, RACH) less PUSCH, uplink activation signal, uplink wake-up signal, sounding reference signal (Sounding Reference Signal, SRS), Msg3 PUSCH, Msg5 PUSCH, at least one signal.

[0093] The resource information determination method, apparatus, and related equipment provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

[0094] Please refer to Figure 2, which is a flow chart of a method for determining resource information provided by an embodiment of the present application, wherein the method is applied to a terminal. As shown in Figure 2, the method includes the following steps:

[0095] Step 201: The terminal determines first sending resource information according to first information, where the first sending resource information is related to at least one of a forwarding time, a forwarding frequency, and a forwarding behavior of a RIS;

[0096] The first information includes at least one of the following:

[0097] First, send resource configuration information;

[0098] An association relationship between the first sending resource and the first reference signal.

[0099] In an embodiment of the present application, the first sending resource information is related to at least one of the forwarding time, forwarding frequency, and forwarding behavior of the RIS. For example, taking the first sending resource information as the sending resource information of the RIS as an example, the sending resource of the RIS (i.e., the first sending resource) can be understood as the time and frequency at which the RIS will forward, as well as the corresponding forwarding behavior of the RIS. For the same RIS sending resource information or configuration, it can be understood that at these time and / or frequency positions, the RIS will perform the same forwarding behavior (for example, forwarding to the same beam); for different RIS sending resource information or configurations, it can be understood that at these time and / or frequency positions, the RIS will perform different forwarding behaviors (for example, forwarding to different beams).

[0100] Among them, "same or different RIS transmission resource information or configuration" can be extended to the same or different transmission behaviors under the same transmission (Tx), or the transmission of the same or different Tx, such as the same or different repeater forwarding or forwarding behavior (such as turning on / off / adjusting the power amplification gain of the repeater, etc.), or the same or different TRP / TAG transmission, or the same / different cell (macro / femto, TN / NTN, etc.) transmission, etc.

[0101] Optionally, the first sending resource information includes at least one of the following:

[0102] 1) Period or time window information of a sending resource of the RIS, where the period or time window information is in a first time granularity, such as a time slot, a radio subframe, or a radio frame;

[0103] 2) frequency information of transmission resources of the RIS, where the frequency information is in units of a first frequency granularity, such as a carrier, a carrier portion, a partial bandwidth, a subcarrier, a physical resource block (PRB), Hertz (Hz), a serving cell, etc.;

[0104] 3) Information about the actual transmission resource locations forwarded by the RIS during the RIS transmission period. The transmission resource location information may be indicated by a network-side device, for example, by a bitmap indicating at which time locations and / or frequency unit locations (e.g., time slot / radio subframe / radio frame / subcarrier / PRB / Hz) the RIS forwards the signal;

[0105] 4) RIS transmission resource position information corresponding to different first reference signals within the RIS transmission period, that is, RIS transmission time positions and / or frequency unit positions corresponding to different first reference signals (such as SSB, Channel State Information Reference Signal (CSI-RS)), or understood as the first reference signal corresponding to each time position and / or frequency position within the RIS transmission period.

[0106] It should be noted that the sending time and / or frequency unit is in units of a second time granularity (eg, time slot / radio subframe / radio frame, etc.) or a second frequency granularity (eg, subcarrier / PRB / Hz, etc.).

[0107] Optionally, the first time granularity and the second time granularity may be the same or different.

[0108] Optionally, the first frequency granularity and the second frequency granularity may be the same or different.

[0109] Exemplarily, the terminal determines first sending resource information (such as the sending resource information of the RIS) based on the first information. For example, the terminal determines the sending resource period of the RIS and the frequency of the sending resource of the RIS based on the first information. Then, the terminal can determine at which time and at which frequency the RIS will forward the signal, thereby further helping to improve the accuracy and reliability of the terminal for receiving signals.

[0110] Alternatively, the terminal determines, based on the first information, the sending resource location information actually forwarded by the RIS within the RIS sending period, where the resource location information includes frequency domain resource location information and time domain resource location information. This allows the terminal to determine at which times and frequencies the RIS actually forwarded the signal, thereby helping to improve the accuracy and reliability of the terminal's received signal.

[0111] Alternatively, the terminal determines, based on the first information, the RIS transmission resource location information corresponding to different first reference signals within the RIS transmission period, and then the terminal can determine its corresponding RIS transmission resource location information based on the selected first reference signal, that is, it can determine the time domain resource location and frequency domain resource location of the RIS for signal forwarding, effectively improving the reliability and accuracy of the terminal's signal reception.

[0112] In an embodiment of the present application, the first information includes first sending resource configuration information and / or an association relationship between the first sending resource and the first reference signal.

[0113] Optionally, the first transmission resource configuration information may be configured by a network-side device to the terminal. For example, the terminal receives first information sent by the network-side device, and the first information includes the first transmission resource configuration information. The terminal can then determine the first transmission resource information based on the first transmission resource configuration information. The first transmission resource configuration information configured by the network-side device is used to configure the first transmission resource. For example, the first transmission resource configuration information may be used to configure at least one of the following:

[0114] The period or time window information of RIS sending resources;

[0115] Frequency information of RIS sending resources;

[0116] The actual resource location information forwarded by RIS during the RIS sending cycle;

[0117] RIS transmission resource location information corresponding to different first reference signals within the RIS transmission period;

[0118] RIS forwarding beam information.

[0119] Alternatively, the first information includes an association between the first transmission resource and the first reference signal, and the terminal can then determine the first transmission resource (e.g., the transmission resource of the RIS) corresponding to the selected first reference signal based on the association, thereby determining the first transmission resource information (e.g., the transmission resource information of the RIS). Optionally, when the first information includes the association between the first transmission resource and the first reference signal, the first information can also be sent to the terminal by a network-side device, that is, the association is determined by the network-side device and then sent to the terminal.

[0120] In an embodiment of the present application, the terminal determines the first transmission resource information based on the first transmission resource configuration information and / or the association between the first transmission resource and the first reference signal. The first transmission resource information is related to at least one of the forwarding time, forwarding frequency, and forwarding behavior of the RIS. Therefore, when the RIS is in a non-transparent mode, the terminal can determine at which times and / or at which frequencies the RIS will forward signals, as well as the corresponding forwarding behavior of the RIS, which can effectively improve the accuracy and reliability of the terminal's signal reception when the RIS is in a non-transparent mode.

[0121] Optionally, when the terminal determines the first transmission resource information based on the association relationship between the first transmission resource and the first reference signal, the association relationship between the first transmission resource and the first reference signal is determined by pre-configuration or based on the first information sent by the network-side device. For example, the association relationship between the first transmission resource and the first reference signal is determined by pre-configuration. In this case, the network-side device does not indicate or determine the association relationship between the first transmission resource and the first reference signal, and the first information may include the pre-configuration. Alternatively, the association relationship between the first transmission resource and the first reference signal may be indicated or determined by the network-side device. In this case, the network-side device sends the first information to the terminal, and the terminal can determine the first transmission resource information based on the association relationship between the first transmission resource and the first reference signal indicated in the first information, and then based on the first reference signal selected by itself, thereby ensuring that the terminal receives the RIS forwarding signal.

[0122] Optionally, in an embodiment of the present application, different first transmission resource information is indicated by different bitmaps, and the different bitmaps are associated with different RIS forwarding beams. For example, different bitmaps / patterns / groups represent different RIS transmission resource information, and different bitmaps / patterns / groups can be associated with different RIS forwarding beams / different repeater transmissions / different cell transmissions. In other words, different first transmission resource information can be associated with different RIS forwarding beams, different repeater transmissions, or different cell transmissions.

[0123] Optionally, the first sending resource information is indicated in at least one of the following ways:

[0124] Dynamic indication, such as through physical layer signaling or the Medium Access Control-Control Element (MAC-CE);

[0125] Semi-static indications, such as Radio Resource Control (RRC) indications, such as system message indications;

[0126] The protocol stipulates, for example, that the protocol stipulates first sending resource information, and these first sending resource information can be used directly based on the protocol provisions in the communication between the terminal and the network side device; or, the protocol stipulates some patterns, each pattern includes the first sending resource information corresponding thereto, and the network side device indicates a certain pattern to the terminal, thereby indicating the first sending resource information.

[0127] It can be understood that the above indication makes the indication method for the first sending resource information more flexible.

[0128] Optionally, in an embodiment of the present application, the method further includes:

[0129] The terminal sends a first signal according to a first signal resource corresponding to the selected first reference signal;

[0130] The first signal resource is an uplink resource, and the first signal is a signal related to the uplink resource.

[0131] Exemplarily, the terminal sends a first signal (e.g., PRACH) based on a first signal resource (e.g., RO or Preamble) corresponding to a selected first reference signal (e.g., SSB or CSI-RS). In this way, when the terminal determines the selected first reference signal, it can also determine the uplink resource corresponding to the first reference signal, thereby sending a signal related to the uplink resource through the first signal resource, thereby better clarifying the terminal's sending behavior for uplink resource-related signals.

[0132] Optionally, the method may further include:

[0133] The terminal determines downlink resource location information based on at least one of the first sending resource information and downlink resource configuration information.

[0134] It should be noted that the downlink resource configuration information may be configured by the network side device to the terminal. It is understandable that in the communication between the terminal and the network side device, the terminal can perform downlink resource transmission according to the downlink resource configuration information configured by the network side device.

[0135] Exemplarily, the terminal can determine downlink resource location information based on the first sending resource information, such as resource location information of a downlink channel (such as PDSCH or PDCCH) and a downlink signal (such as TRS / PRS / Wake Up Signal (WUS)), and the resource location information includes frequency domain resource location information and time domain resource location information.

[0136] For another example, the terminal may determine downlink resource location information, such as PDCCH / PDSCH / TRS / PRS transmission location information, based on the first transmission resource information and downlink resource configuration information. Of course, the terminal may also determine downlink resource location information based only on the downlink resource configuration information.

[0137] In an embodiment of the present application, the terminal can determine the downlink resource location information based on at least one of the first sending resource information and the downlink resource configuration information, thereby effectively improving the flexibility of the method for determining the downlink resource location information.

[0138] Optionally, the downlink resource configuration information includes a downlink resource configuration forwarded via RIS and a downlink resource configuration forwarded without RIS; wherein the downlink resource (such as PDCCH / TRS / PRS / PDSCH) configuration forwarded via RIS and the downlink resource configuration forwarded without RIS are independent configurations, that is, the two are different configurations; or, the downlink resource configuration forwarded via RIS and the downlink resource configuration forwarded without RIS are the same configuration, that is, the two can share the same configuration.

[0139] Optionally, when the downlink resource configuration forwarded via the RIS and the downlink resource configuration forwarded without the RIS are independent configurations, the retransmission or repeated transmission of the downlink signal satisfies any one of the following conditions:

[0140] The retransmission or repeated transmission of the downlink signal does not use the downlink resources configured by the downlink resource configuration forwarded by the RIS, which can be understood as the retransmission or repeated transmission of the downlink signal uses the downlink resources configured by the downlink resource configuration not forwarded by the RIS;

[0141] The retransmission or repeated transmission of the downlink signal all uses the downlink resources configured by the downlink resource configuration forwarded by the RIS;

[0142] The retransmission or repeated transmission of part of the downlink signals uses the downlink resources configured by the downlink resource configuration forwarded by the RIS, and the retransmission or repeated transmission of part of the downlink signals does not use the downlink resources configured by the downlink resource configuration forwarded by the RIS.

[0143] It should be noted that the terminal may determine, based on an instruction from the network device, or based on a protocol agreement or pre-configuration, whether the network device uses the downlink resources configured by the downlink resource configuration forwarded via the RIS to retransmit or repeat downlink signals, or may use the downlink resources configured by the downlink resource configuration forwarded via the RIS for the retransmission or repeat of some downlink signals, while not using the downlink resources configured by the downlink resource configuration forwarded via the RIS for the retransmission or repeat of other downlink signals. This makes the retransmission or repeat transmission of downlink signals more flexible.

[0144] Optionally, when the downlink resource configuration forwarded via the RIS and the downlink resource configuration forwarded without the RIS are independent configurations, the method further includes:

[0145] The terminal receives first indication information sent by a network-side device, where the first indication information is used to indicate whether retransmission or repeated transmission of a downlink signal uses the downlink resources configured by the downlink resource configuration forwarded by the RIS.

[0146] That is, the terminal may also determine, according to an instruction from the network-side device, whether to use the downlink resources configured by the downlink resource configuration forwarded by the RIS for retransmission or repeated transmission of the downlink signal.

[0147] Optionally, in an embodiment of the present application, the method further includes:

[0148] The terminal determines a first time unit set based on the downlink resource location information;

[0149] The terminal determines a time position of a downlink resource from the first time unit set based on the first sending resource information.

[0150] That is, the time position of the downlink resource belongs to both the time position determined based on the downlink resource position information and the time position determined based on the sending resource of the RIS.

[0151] Alternatively, in some embodiments, the terminal determines the time position of the downlink resource according to the intersection of the first time unit set and the second time unit set;

[0152] The first time unit set is a RIS transmission time unit set determined based on the first transmission resource information, and the second time unit set is a time unit set determined based on downlink resource location information (such as a time unit set determined based on a PDCCH monitoring period and an offset value).

[0153] Exemplarily, the time position of the downlink resources (such as PDCCH, PRS / TRS) is the intersection of the first time unit set and the second time unit set. In this case, the network-side device can ensure that the intersection of the first time unit set and the second time unit set determined based on the first sending resource information and the downlink resource configuration information is not empty, thereby ensuring that the terminal can determine the time position of the downlink resources based on the intersection of the first time unit set and the second time unit set.

[0154] In an embodiment of the present application, the terminal can determine the time position of the downlink resource based on the RIS sending time unit set determined based on the first sending resource information and the time unit set determined based on the downlink resource location information, thereby enabling the terminal to determine at which time to receive the downlink resource, thereby effectively ensuring the reliability and accuracy of the terminal's reception of the downlink resource.

[0155] Optionally, the terminal determines a RIS transmission time unit set based on the first transmission resource information, and the RIS transmission time unit set is associated with the first reference signal selected by the terminal. For example, the association between the RIS transmission time unit set and the first reference signal may be preconfigured or predefined, so that the terminal determines the RIS transmission time unit based on the RIS transmission resource information. Based on the RIS transmission time unit, the terminal can also determine the selected first reference signal, thereby facilitating the terminal's determination of the first reference signal selection.

[0156] Optionally, in an embodiment of the present application, the method further includes:

[0157] The terminal determines downlink resource location information according to the second information, where the second information includes at least one of the following:

[0158] RIS sends time units;

[0159] Non-RIS send time unit.

[0160] For example, the terminal may determine downlink resource location information based on the RIS transmission time unit, such as determining the time location of the downlink resource. Alternatively, the terminal may determine the downlink resource location information based on the RIS transmission time unit and the non-RIS transmission time unit. This allows the terminal to more flexibly determine the downlink resource location information.

[0161] Optionally, the RIS sending time unit is associated with a first reference signal (such as SSB / CSI-RS) selected by the terminal.

[0162] It should be noted that in some implementations, parameter values ​​related to the temporal location of downlink resources are calculated only in RIS transmission time units, or these parameter values ​​may include RIS transmission time units and non-RIS transmission time units. For example, the monitoring period and time offset value of the PDCCH search space are calculated only in RIS transmission time units; the period and offset value of the TRS / PRS are calculated only in RIS transmission time units, etc.; the time slot offset value (e.g., K0) of a data channel (e.g., PDSCH) relative to its control channel (e.g., PDCCH) is calculated only in RIS transmission time units; or the time slot offset value (e.g., K0) of a data channel (PDSCH) relative to its control channel (PDCCH) includes both RIS transmission time units and non-RIS transmission time units.

[0163] Optionally, the parameter values ​​related to the time position of the downlink resource are configured in units of the transmission resource period of the RIS. For example, the monitoring period of the PDCCH search space and / or the period of the TRS and / or PRS are configured in units of the transmission resource configuration period of the RIS.

[0164] In addition, in some embodiments, the terminal does not expect the data channel (e.g., PDSCH) scheduled by the control channel (e.g., PDCCH) to be received in a non-RIS transmission time unit. That is, the terminal requires the network device to schedule the data channel to the RIS transmission time unit. The data channel may be a PDSCH carrying a RAR or Msg4, and the PDCCH is the PDCCH that schedules the PDSCH.

[0165] In the embodiment of the present application, the method further includes:

[0166] The terminal determines a time length and a start position of a RAR window (RAR window), and receives a RAR based on the RAR window; wherein the RAR is a RAR forwarded through a RIS or a RAR associated with a specific reference signal.

[0167] In the embodiment of the present application, when the RAR is a RAR forwarded through a RIS or a RAR associated with a specific reference signal, the terminal can determine the time length and starting position of the RAR window for receiving such RAR, and thus can receive such RAR within the starting position and the time length, effectively ensuring the reliability and accuracy of the terminal's reception of the RAR forwarded by the RIS or the RAR associated with the specific reference signal.

[0168] Optionally, the RAR window satisfies at least one of the following:

[0169] The RAR window includes at least one PDCCH monitoring opportunity within the RIS transmission time unit;

[0170] The starting position of the RAR window is located within the RIS sending time unit;

[0171] The RAR window only counts the RIS sending time unit;

[0172] The RAR window is determined in units of the sending period of RIS;

[0173] In the case that the cell corresponding to the terminal is a cell supporting RIS transmission, the configuration of the RAR window is a specific configuration, for example, a longer RAR window length may be configured relative to a cell that does not support RIS transmission.

[0174] It should be noted that the terminal may determine the RAR window based on at least one of the above items. For example, the terminal may determine the RAR window by determining the starting position of the RAR window within the RIS transmission time unit, or the terminal may determine the RAR window based on the RIS transmission period, etc. This allows the terminal to more flexibly and diversely determine the RAR window for receiving the RAR forwarded via the RIS or the RAR associated with a specific reference signal.

[0175] Optionally, when the RAR window only calculates the RIS transmission time unit, the RIS transmission time unit is associated with the first reference signal selected by the terminal. Consequently, the terminal can determine the associated RIS transmission time unit based on the selected first reference signal, thereby facilitating the terminal to determine the RAR window based on the RIS transmission time unit.

[0176] Please refer to Figure 3, which is a flowchart of another resource information determination method provided by an embodiment of the present application, the method is applied to a network side device. As shown in Figure 3, the method includes the following steps:

[0177] Step 301: A network-side device sends first information to a terminal, where the first information is used by the terminal to determine first sending resource information, where the first sending resource information is related to at least one of a forwarding time, a forwarding frequency, and a forwarding behavior of a RIS.

[0178] The first information includes at least one of the following:

[0179] First, send resource configuration information;

[0180] An association relationship between the first sending resource and the first reference signal.

[0181] For example, the first information includes first sending resource configuration information, that is, the first sending resource configuration information is configured by the network side device to the terminal, and the first sending resource configuration information is used to configure the first sending resource. The terminal receives the first information sent by the network side device, and can determine the first sending resource information based on the first sending resource configuration information included in the first information.

[0182] Alternatively, the first information sent by the network side device to the terminal includes the association relationship between the first sending resource and the first reference signal, and then the terminal can determine the first sending resource corresponding to the first reference signal based on the association relationship according to the selected first reference signal, and thus can determine the first sending resource information.

[0183] Optionally, the first sending resource information includes at least one of the following:

[0184] The period or time window information of RIS sending resources;

[0185] Frequency information of RIS sending resources;

[0186] The actual resource location information forwarded by RIS during the RIS sending cycle;

[0187] RIS transmission resource location information corresponding to different first reference signals within the RIS transmission period;

[0188] RIS forwarding beam information.

[0189] Optionally, different first sending resource information is indicated by different bitmaps, and the different bitmaps are associated with different RIS forwarding beams.

[0190] Optionally, the first sending resource information is indicated in at least one of the following ways:

[0191] Dynamic indication;

[0192] semi-static indication;

[0193] Agreement provisions.

[0194] Optionally, the method further includes:

[0195] The network side device sends first indication information to the terminal, where the first indication information is used to indicate whether retransmission or repeated transmission of a downlink signal uses the downlink resources configured by the downlink resource configuration forwarded by the RIS.

[0196] It should be noted that the method applied to the network side device provided in the embodiment of the present application corresponds to the above-mentioned method applied to the terminal side. The specific processes and related concepts involved in the embodiment of the present application can refer to the description in the above-mentioned terminal side method embodiment, and can achieve the corresponding technical effects. To avoid repetition, they will not be repeated here.

[0197] Optionally, in an embodiment of the present application, the method further includes:

[0198] The network-side device receives a first signal sent by the terminal, and determines a target first reference signal selected by the terminal according to the first signal, wherein the first signal is a signal related to uplink resources;

[0199] The network-side device determines, according to an association relationship between the first sending resource and the first reference signal, a first sending resource corresponding to the target first reference signal;

[0200] The network-side device determines downlink resource location information according to the first sending resource corresponding to the target first reference signal.

[0201] For example, a network-side device receives a first signal (e.g., PRACH) sent by a terminal. The first signal is sent by the terminal based on a first signal resource (e.g., RO or Preamble) corresponding to a selected first reference signal. Based on the first signal resource corresponding to the first signal, the network-side device can determine the target first reference signal selected by the terminal. Furthermore, based on the association between the first transmission resource and the first reference signal, the network-side device can determine the first transmission resource (e.g., RIS transmission resource) corresponding to the target first reference signal. Based on the first transmission resource, the network-side device determines downlink resource location information, and thus determines which RIS transmission resources to use to send downlink signals to the terminal. This effectively ensures the transmission of downlink signals by the network-side device and helps improve the reliability of the terminal's reception of downlink signals.

[0202] In an embodiment of the present application, a network-side device sends first information to a terminal, where the first information includes first transmission resource configuration information and / or an association between the first transmission resource and a first reference signal, so that the terminal can determine the first transmission resource information based on the first information. The first transmission resource information is related to at least one of the forwarding time, forwarding frequency, and forwarding behavior of the RIS. Thus, the terminal can determine at which time and / or at which frequency the RIS will forward the signal, as well as the corresponding forwarding behavior of the RIS, which can effectively improve the accuracy and reliability of the terminal's signal reception when the RIS is in non-transparent mode.

[0203] For better understanding, the following takes the case where the first sending resource information is the sending resource information of RIS and the first sending resource is the sending resource of RIS as an example to illustrate the technical solution provided by the present application through several specific embodiments.

[0204] Example 1: Determination of RIS Transmission Resource Information

[0205] RIS transmission resources refer to the times and frequencies at which RIS forwards, as well as the corresponding RIS forwarding behavior. For identical RIS transmission resource information / configuration, the RIS will perform the same forwarding behavior (e.g., forwarding to the same beam) at those times / frequencies. For different RIS transmission resource information / configuration, the RIS will perform different forwarding behaviors (e.g., forwarding to different beams) at those times / frequencies.

[0206] "Same / different RIS transmission resource information / configuration" can be expanded to the same / different transmission behaviors under the same Tx, or the transmission of the same / different Txs, such as the same / different repeater forwarding or forwarding behavior (such as turning on / off / adjusting the repeater power amplifier gain, etc.), or the same / different TRP / TAG transmission, or the same / different cell (macro / femto, TN / NTN, etc.) transmission, etc.

[0207] The RIS sending resource information includes:

[0208] 1) RIS sending resource cycle or time window information;

[0209] 2) Information about the actual location of transmission resources forwarded by the RIS during the RIS transmission cycle, i.e., the transmission configuration for different time units in the transmission cycle, for example, to which location the RIS will forward the base station's downlink signal in each time unit during the transmission cycle, or from which location the RIS will forward the terminal's uplink signal to the base station;

[0210] The sending period and the time unit in the sending period can be in the granularity of time slot / radio subframe / radio frame, and the frequency unit can be carrier / carrier part / partial bandwidth / subcarrier / PRB / Hz / service cell. This application does not make specific restrictions.

[0211] 3) Frequency information of the transmission resources of the RIS, for example, which frequency units' signals will the RIS forward to which location. The frequency information can be expressed in units such as carrier / carrier part / partial bandwidth / subcarrier / PRB / Hz / serving cell, and this application does not impose any specific restrictions.

[0212] 4) The association between the RIS transmission resource and the first reference signal. For example, the RIS transmission resource period / the resource location / frequency information forwarded by the RIS within the period can be associated with the first reference signal (e.g., SSB / CSI-RS). Alternatively, different first reference signals (e.g., different SSB / CSI-RS) correspond to different RIS transmission time locations / frequency unit locations.

[0213] For example, as shown in Figure 4a, the RIS can forward signals from the base station to three different locations. The RIS transmission period is five radio frames, with each time unit being one radio frame. In the first time unit of the RIS transmission period, radio frame #0, the RIS forwards the base station's signal to beam #0 or forwards the uplink signal from beam #0 to the base station. In radio frame #1, the RIS forwards the base station's signal to beam #1 or forwards the uplink signal from beam #1 to the base station. In radio frame #2, the RIS forwards the base station's signal to beam #2 or forwards the uplink signal from beam #2 to the base station. The RIS transmission configuration is shown in Figure 4b. The RIS does not forward signals in radio frames #4 and #5.

[0214] The terminal determines the transmit resource information of the RIS: The network-side device may directly configure the transmit resource information of the RIS for the terminal, or the terminal may pre-configure the transmit resource information of the RIS, or the transmit resource information of the RIS may be associated with the first reference signal (e.g., SSB or CSI-RS). For example, the SSB or CSI-RS corresponds to different downlink beams, and the terminal determines the transmit resource configuration information of the RIS based on the SSB / CSI-RS. The RIS transmit resource information associated with the SSB / CSI-RS may be pre-configured or determined by the terminal at the instruction of the network side.

[0215] For example, after the terminal selects a certain SSB / CSI-RS, it uses the uplink signal resources (such as PRACH resources) corresponding to the selected SSB / CSI-RS to initiate random access. The base station determines the SSB / CSI-RS selected by the terminal based on the random access resources used by the terminal, and further schedules the downlink channel based on the RIS sending time corresponding to the SSB / CSI-RS. The terminal determines the time to receive the downlink channel or signal based on the RIS sending time corresponding to the SSB / CSI-RS.

[0216] For example, in Figure 4a, there are three beams under the RIS, corresponding to SSB#0, SSB#1, and SSB#2. The RIS transmission period is preconfigured to five radio frames. The RIS transmission time associated with SSB#0 is the first radio frame within each RIS transmission period. That is, within the first radio frame of the transmission period, the RIS will forward the downlink signal from the base station to beam#0 or forward the uplink signal corresponding to beam#0 to the base station. After selecting SSB#0, the terminal uses the PRACH resource corresponding to SSB#0 to initiate random access. The base station sends downlink resources, such as PDCCH / PDSCH, based on the RIS transmission time corresponding to SSB#0. The terminal also determines the PDCCH / PDSCH based on the RIS transmission time corresponding to SSB#0, thereby ensuring the reliability of the terminal's reception of downlink resources.

[0217] Example 2: Determination of Downlink Resource (eg, PDCCH / TRS / PRS / PDSCH) Location

[0218] The downlink resource configuration (such as PDCCH / TRS / PRS) forwarded by RIS and the downlink resource configuration not forwarded by RIS can be independent configurations, or the downlink resource configuration (such as PDCCH / TRS / PRS) forwarded by RIS and the downlink resource configuration not forwarded by RIS can be the same configuration.

[0219] When the downlink resource configuration forwarded via RIS and the downlink resource configuration forwarded without RIS are independently configured, the retransmission or repeated transmission of downlink signals (e.g., retransmission or repeated transmission of PDCCH / PDSCH) may satisfy any of the following conditions:

[0220] Retransmission or repeated transmission does not use the downlink resources configured by the downlink resource configuration forwarded by RIS;

[0221] Retransmissions or repeated transmissions all use the downlink resources configured by the downlink resource configuration forwarded by RIS;

[0222] Part of the retransmission or repeated transmission uses the downlink resources configured by the downlink resource configuration forwarded by the RIS, and the other part of the retransmission or repeated transmission does not use the downlink resources configured by the downlink resource configuration forwarded by the RIS.

[0223] In addition, whether retransmission or repeated transmission uses the downlink resources configured by the downlink resource configuration forwarded by RIS can be determined by network pre-configuration or dynamic indication, for example, pre-configured retransmission still uses the downlink resources configured by the downlink resource configuration forwarded by RIS, or pre-configured retransmission uses the downlink resources configured by the downlink resource configuration not forwarded by RIS, or dynamic indication of which type of downlink resources to use during retransmission, for example, during initial transmission, the network dynamically instructs the terminal which type of downlink resources to use during retransmission.

[0224] The time position of downlink resources (such as PDCCH, PRS / TRS) is the intersection of the first time unit set and the second time unit set:

[0225] For example, for PDCCH / TRS / PRS, a first time unit set is determined based on the configured period and offset value. The terminal side determines the RIS transmission time of the beam corresponding to the selected SSB / CSI-RS based on the selected SSB / CSI-RS as the second time unit set. The intersection of the first time unit set and the second time unit set is the third time unit set, and the terminal monitors or receives PDCCH / TRS / PRS based on the third time unit set. When configuring the time domain period and offset value of PDCCH / TRS / PRS, the network side needs to ensure that the third time unit set is not an empty set.

[0226] For example, for the PDCCH, the corresponding search space configuration is: a monitoring period of 4 slots, and a time offset within the monitoring period of 0 slots. Based on this configuration, the first time set can be determined, as shown by the shaded area in Figure 4c. Assuming the RIS transmission period is 6 slots, and the SSB selected by the terminal corresponds to beam #0, the corresponding RIS transmission time is the second time set, as shown by the shaded area in Figure 4d. The third time set determined based on the first and second time sets is shown by the shaded area in Figure 4e.

[0227] It should be noted that the PDCCH / TRS / PRS time-frequency domain parameter configuration information under RIS is configured separately and is associated with the transmission configuration information of RIS.

[0228] Optionally, the period and offset of TRS / PRS are calculated only in the RIS transmission time unit.

[0229] For example, in Figure 4a, the RIS transmission period is one system frame (containing 10 time slots), with a total of three beams, each corresponding to two slots within the transmission period, as shown in Figure 4f. Assuming the TRS period is 10 time slots and the offset within the period is 0, when determining the TRS's time domain position, only the RIS transmission time units are calculated. That is, the TRS period only contains the RIS transmission time units. The TRS transmission time can be determined as shown by the shaded area in Figure 4g.

[0230] Optionally, the monitoring period and time offset of the PDCCH search space only calculate the RIS transmission time unit, for example, only calculate the RIS transmission time unit of the beam corresponding to the selected SSB / CSI-RS.

[0231] For example, in Figure 4f, assuming the SSB corresponding to the terminal's selected beam is beam#0, only the RIS transmission time unit corresponding to beam#0 is calculated when determining the monitoring period and time offset of the PDCCH search space. For example, if the PDCCH search space monitoring period is 2 and the offset within the monitoring period is 0, the PDCCH monitoring time can be determined as shown in the shaded area in Figure 4h.

[0232] The monitoring period of the PDCCH search space and the TRS / PRS period are configured in units of the RIS transmission period. The PDCCH / TRS / PRS time parameter configuration under RIS can be based on the RIS transmission period. For example, if the RIS transmission period is 10 time slots, the PDCCH search space configuration is: the monitoring period is 2 RIS transmission periods, a total of 20 time slots.

[0233] The PDSCH reception time can be determined by:

[0234] The network-side device ensures that the PDSCH reception time scheduled by the PDCCH falls within the RIS transmission time of the SSB / CSI-RS corresponding beam selected by the terminal;

[0235] The time slot offset value K0 of the PDSCH relative to the PDCCH is only calculated for the selected RIS transmission time unit, for example, only the RIS transmission time unit of the beam corresponding to the SSB / CSI-RS is calculated.

[0236] For example, as shown in FIG4i , assuming that the beam corresponding to the SSB selected by the terminal is beam#2 and K0=1, the position of the PDSCH scheduled by the PDCCH is the first time slot within the RIS transmission time corresponding to beam#2, which is after the time slot where the PDCCH is located.

[0237] Example 3: Determination of RAR Window during Random Access

[0238] It should be noted that the RAR is an RAR forwarded through the RIS or an RAR associated with a specific reference signal (the specific reference signal here corresponds to the RIS resource). The determination of the RAR window needs to meet one or more of the following conditions:

[0239] 1) The RAR window duration configuration must satisfy the following requirements: The RAR window must contain at least one PDCCH monitoring opportunity within the RIS transmission time unit of the selected SSB / CSI-RS beam. This means that the RIS transmission time unit of the beam selected by the terminal must exist within the RAR window, and at least one PDCCH monitoring opportunity must be within that RIS transmission time unit.

[0240] 2) The start time of the RAR window needs to be determined within the RIS transmission time of the SSB / CSI-RS corresponding beam selected by the terminal. That is, the start time of the RAR window is determined under the premise that the RIS transmission time of the SSB / CSI-RS corresponding beam selected by the terminal is within the RIS transmission time;

[0241] 3) The time units included in the RAR window only calculate the RIS transmission time units. For example, only the RIS transmission time units corresponding to the selected SSB / CSI-RS beam can be calculated;

[0242] Optionally, the RIS sending time unit is associated with a selected first reference signal (such as SSB / CSI-RS).

[0243] 4) The RAR window is configured based on the RIS transmission period. For example, if the RIS transmission period is 10 time slots, the RAR window duration is configured to be 4 RIS transmission periods, for a total of 40 time slots.

[0244] 5) For cells that support RIS transmission, a specific RAR window configuration is used; for example, a longer RAR window length can be configured relative to cells that do not support RIS transmission.
