[0073] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102, wherein the network device includes at least one of the following: an access network device and a core network device.
[0074] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.
[0078] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0079] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0080] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1.

[0081] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0082] In some embodiments, for wireless access networks, cell search is one of the key steps for a terminal to access the network. Before completing a cell search, the terminal cannot obtain network information or the type of access network.
[0083] For example, cell search can include three steps:
[0084] SSB (Synchronization Signal Block) reception;
[0085] SIB (System Information Block) 1 and OSI (Other System Information) reception;
[0086] Paging reception.
[0087] After completing the above steps, the terminal can access the wireless network and remain logged in.
[0088] In the first step described above, the terminal can complete downlink coarse synchronization and obtain frame timing based on the PSS (Primary Synchronization Signal) and SSS (Secondary Synchronization Signal) in the SSB. The terminal can also obtain the most critical network configuration information based on the MIB (Master Information Block) information carried on the PBCH (Physical Broadcast Channel) in the SSB. Due to the importance and special nature of PBCH, PSS, and SSS, they are often considered core design elements of each generation of systems.
[0089] After completing cell search, the terminal needs to obtain uplink synchronization information in order to subsequently obtain terminal-specific network configuration information and send uplink data. For example, in a 5G system, the terminal needs to obtain RACH (Random Access Channel) related information based on the cell-specific configuration information provided by SIB1 and complete the corresponding uplink synchronization operation.
[0090] As can be seen, during the above process, network devices need to periodically send and / or receive channels and / or signals, which consumes a significant amount of energy. Even under low network load, network devices still need to complete these sending and / or receiving operations to avoid negatively impacting user experience. Moreover, during this process, network devices cannot enter a sleep state to conserve energy, resulting in substantial energy waste and increasing the operator's operating expenses (OPEX).
[0091] In some embodiments, SSB and SIB1 may periodically transmit on determined time-frequency resources according to the period agreed upon in the protocol and / or the period configured by the network device.
[0092] In some embodiments, an SSB occupies four consecutive orthogonal frequency division multiplexing (OFDM) symbols in the time domain, including PSS, SSS, and PBCH.
[0093] In some embodiments, the NR system supports five SSB time-domain transmission scenarios (cases): case A (SCS = 15KHz, operating in frequency bands above 3GHz), case B (SCS = 30KHz, operating in frequency bands above 3GHz), case C (SCS = 30KHz, TDD and operating in frequency bands above 3GHz), case D (SCS = 120KHz, operating in FR2 frequency band), and case E (SCS = 240KHz, operating in FR2 frequency band).
[0094] In some embodiments, the time-domain pattern of the SBB in each scenario depends on factors such as the sub-carrier space (SCS), operating frequency, time-division duplex (TDD) standard, and frequency-division duplex (FDD) standard of the SBB.
[0095] For example, different scenarios can correspond to the number of SSBs within an SSB burst and the temporal resource location occupied within that burst. For example, the duration of an SSB burst is 5ms; for example, the transmission period of an SSB is 20ms.
[0096] Furthermore, network devices can configure the SSB transmission period and time-domain pattern through System Information Blocks (SIBs), such as SIB1, carrying relevant information. The maximum transmission period of the SSB is 160ms. For different cases, the SSB pattern can be found in relevant technologies, which will not be elaborated here.
[0097] In some embodiments, the terminal can determine the time-frequency resources available for PRACH (Physical Random Access Channel) transmission based on the configuration information provided by SIB1 or UE-dedicated RRC signaling. For example, the terminal and network device combine the above configuration information and further determine the valid RO (Random Access Occasion) that can actually be used for PRACH transmission based on the TDD (Time Division Duplexing) structure, SSB time domain location, downlink transmission, and other related information. Further, the network device and terminal determine the mapping relationship between SSBs and ROs based on the aforementioned configuration information, SSB configuration, and valid ROs, so that the terminal can send a preamble bound to its own related SSBs on the determined valid ROs according to its own needs. For example, PRACH resource configuration information is configured through semi-static signaling and cannot be dynamically adjusted.
[0098] In some embodiments, the terminal can determine the slot in which the paging transmission occurs according to the configuration information provided by SIB1. For example, the terminal and the network device determine the paging frame in which the paging transmission occurs within the DRX (Discontinuous Reception) cycle, the PO (paging occasion) in which the paging transmission occurs within the paging frame, and the PMO (paging monitor occasion) contained within the PO, based on the configuration information described above.
[0099] In some embodiments, network energy savings (NES) can be achieved by reducing the ineffective power consumption of network devices based on at least one of the following methods:
[0100] SCell secondary cells introduce on-demand SSBs;
[0101] For non-connected terminals, an on-demand SSB is introduced, where the non-connected state can include an idle state and an inactive state;
[0102] SSB adaptation is introduced for SCell;
[0103] PARCH adaptation is introduced for the primary cell (PCell) and SCell;
[0104] For paging transmission, paging adaptation is introduced.
[0105] As can be seen, there are multiple ways to implement NES, but the implementation paths of different NESs can be different. For example, some NESs need to indicate energy-saving information through RRC (Radio Resource Control), while others indicate energy-saving information through broadcast information. This can easily lead to different NESs being unable to coordinate with each other and is not conducive to forward compatibility and scalability.
[0106] Figure 2 is an interactive schematic diagram of an information receiving method according to an embodiment of the present disclosure.
[0107] In some embodiments, the information receiving method may be executed by the terminal.
[0108] As shown in Figure 2, the information receiving method may include the following steps:
[0109] In step S201, the instruction information sent by the network device is received.
[0110] For example, the instruction information can indicate the method of receiving the first DCI (also referred to as the action of receiving the first DCI).
[0111] In some embodiments, the first DCI is used to indicate energy-saving information.
[0112] In step S202, the terminal determines the method of receiving the first DCI.
[0113] For example, the terminal can determine the method of receiving the first DCI based on the instruction information.
[0114] For example, the terminal can determine the method of receiving the first DCI according to predefined rules (e.g., protocol agreement), in which case step S201 can be omitted.
[0115] In this embodiment, network devices can uniformly indicate energy-saving information to terminals through the first DCI. Accordingly, it can be ensured that the path of each energy-saving method of the network device is based on the first DCI indication, which is conducive to the coordination between different energy-saving methods and the forward compatibility and scalability of energy-saving operations.
[0116] Since the first DCI is used to carry energy-saving information, this function is different from the traditional function of DCI (such as scheduling downlink channels). Therefore, the way the terminal receives the first DCI may be different from the way it receives DCI used for traditional functions. Therefore, it is necessary to specify the way the first DCI is received.
[0117] According to embodiments of this disclosure, a predefined rule can specify the method of receiving the first DCI, or the indication information of the network device can indicate the method of receiving the first DCI. Accordingly, it can be ensured that the terminal receives the first DCI in a clear manner, thereby correctly receiving the first DCI.
[0118] In some embodiments, the method for receiving the first DCI includes at least one of the following:
[0119] Receive the first DCI in the newly defined Common Search Space (CSS);
[0120] Receive the first DCI in a CSS that is not dedicated to transmitting the first DCI.
[0121] For example, a new CSS can be defined, and a network device can send the first DCI within the newly defined CSS, while a terminal can receive the first DCI within the newly defined CSS. For example, the newly defined CSS can be a CSS specifically designed for transmitting the first DCI.
[0122] For example, a network device may transmit the first DCI in a CSS that is not dedicated to transmitting the first DCI. In addition to transmitting the first DCI, the CSS that is not dedicated to transmitting the first DCI may also be used to transmit other DCIs (e.g., referred to as the second DCI), which may be used for other purposes (e.g., scheduling downlink channels).
[0123] In some embodiments, CSS includes at least one of the following: a cell-specific search space; a group common search space.
[0124] In some embodiments, when the first DCI is received in the newly defined CSS, the time-domain resources and / or frequency-domain resources of the newly defined CSS are determined based on one of the following: MIB; SIB; UE-dedicated RRC signaling.
[0125] To determine the newly defined CSS, it is necessary to determine the time domain resources and / or frequency domain resources of the newly defined CSS. The network device can indicate the time domain resources and / or frequency domain resources of the newly defined CSS through MIB, SIB (e.g., SIB1 or other SIB), or RRC signaling (e.g., UE-dedicated RRC signaling).
[0126] In some embodiments, the number of candidate physical downlink control channels (PDCCHs) and / or aggregation level (AL) of the newly defined CSS are determined based on predefined rules or based on indication information from network devices.
[0127] In order to receive the first DCI in the newly defined CSS, it is necessary to determine the number of PDCCH candidates and / or the aggregation level of the newly defined CSS. The number of PDCCH candidates and / or the aggregation level of the newly defined CSS can be indicated by the network device through indication information (such as MIB, SIB, RRC signaling, etc.), or it can be specified by predefined rules.
[0128] In some embodiments, when the first DCI is transmitted in a CSS that is not dedicated to transmitting the first DCI, since the CSS is not dedicated to transmitting the first DCI, for example, it may also transmit a second DCI other than the first DCI, in order to ensure that the terminal can accurately receive the first DCI in the CSS, the terminal needs to determine the first monitoring occasion (also known as the listening occasion) for receiving the first DCI in the CSS.
[0129] For example, the first detection timing for receiving the first DCI in a CSS that is not dedicated to transmitting the first DCI can be specified by a predefined rule. In this case, the terminal can determine the first detection timing for receiving the first DCI in a CSS that is not dedicated to transmitting the first DCI according to the predefined rule.
[0130] For example, the first detection timing for receiving the first DCI in a CSS that is not dedicated to transmitting the first DCI can be indicated by the network device through indication information. In this case, the terminal can determine the first detection timing for receiving the first DCI in a CSS that is not dedicated to transmitting the first DCI based on the indication information of the network device (such as MIB, SIB, RRC signaling, etc.).
[0131] In some embodiments, the CSS not dedicated to transmitting the first DCI includes at least one of the following:
[0132] CSS for DCI used in transport scheduling SIB;
[0133] CSS for DCI used in transport scheduling of Random Access Response (RAR);
[0134] CSS for DCI used in transport scheduling paging;
[0135] CSS used for transmitting group common DCI.
[0136] In some embodiments, since the CSS not dedicated to transmitting the first DCI can transmit not only the first DCI but also DCIs of other functions (e.g., the second DCI), it is necessary to determine whether the DCI in the CSS not dedicated to transmitting the first DCI is the first DCI.
[0137] For example, the terminal can determine whether a DCI is the first DCI based on the format of the DCI in a CSS that is not dedicated to transmitting the first DCI. For example, the format of the first DCI can be a newly defined DCI format.
[0138] For example, a terminal can determine whether a DCI is the first DCI based on the RNTI (Radio Network Temporary Identity) of the DCI in the CSS used to scramble the DCI, which is not dedicated to transmitting the first DCI. For example, by using a newly defined first RNTI (scrambling the first DCI), when the terminal attempts to descramble the DCI using the first RNTI, it can determine that the descrambled DCI is the first DCI.
[0139] For example, the DCI may contain indication information that indicates whether it is intended to carry energy-saving information or for other purposes. Upon receiving the DCI, the terminal can retrieve the indication information. If the indication information indicates that the DCI carries energy-saving information, the terminal can determine that the DCI is the first DCI. If the indication information indicates that the DCI is used for other functions (such as scheduling downlink channels), the terminal can determine that the DCI is not the first DCI.
[0140] In some embodiments, a predefined rule may specify the period of the first detection timing of the first DCI, which is the same as the period of the detection timing of the second DCI in a CSS that is not dedicated to transmitting the first DCI.
[0141] In this scenario, the terminal can determine the period of the first detection timing of the first DCI, which is the same as the period of the detection timing of the second DCI. For example, if the period of the second DCI detection timing is T, and T is known to the terminal, the terminal can receive the second DCI in a CSS that is not dedicated to transmitting the first DCI, or it can receive the first DCI in a CSS that is not dedicated to transmitting the first DCI, based on T.
[0142] In some embodiments, predefined rules may specify the association between the resources of the SSB and the period of at least one detection timing to determine the period of the first detection timing of the first DCI.
[0143] In this scenario, the terminal can determine the period of the detection opportunity corresponding to the received SSB as the period of the first detection opportunity for the first DCI based on the association between the resources of the Synchronization Signal Block (SSB) and the period of at least one detection opportunity. Then, it can receive the first DCI in a CSS (CSS not dedicated to transmitting the first DCI) based on the determined period of the first detection opportunity.
[0144] In some embodiments, the period of the first detection timing of the first DCI can be indicated by the network device through indication information.
[0145] For example, the indication information can be carried in the MIB, and the terminal can determine the period of the first detection timing of the first DCI based on the indication information carried in the MIB.
[0146] For example, the indication information can be carried in the SIB (e.g., SIB1 or other SIBs), and the terminal can determine the period of the first detection timing of the first DCI based on the indication information carried in the SIB.
[0147] For example, the indication information can be carried in the terminal-specific radio resource control signaling, and the terminal can determine the period of the first detection timing of the first DCI based on the indication information carried in the terminal-specific radio resource control signaling.
[0148] In some embodiments, the detection timing of the CSS not dedicated to transmitting the first DCI corresponds to at least one period, and the period of the first detection timing is a subset of at least one period, for example, the subset includes one period.
[0149] The detection timing of the CSS not dedicated to transmitting the first DCI can correspond to multiple periods, such as 10ms, 20ms, 50ms, and 100ms. The terminal can detect the DCI within this CSS based on different periods. Since the first DCI is transmitted within this CSS, it can be transmitted according to one of these periods, for example, 100ms. Correspondingly, when receiving the first DCI, the terminal can detect it according to one of these periods, for example, only 100ms. Therefore, the terminal does not need to receive the DCI within the CSS according to other periods, which helps ensure that the terminal can accurately receive the first DCI within the CSS.
[0150] In some embodiments, energy-saving information includes at least one of the following:
[0151] SSB's periodic adjustment information;
[0152] SSB drawing information;
[0153] SSB structural information;
[0154] Frequency domain location information of the SSB;
[0155] PRACH's resource cycle;
[0156] PRACH's resource diagrams;
[0157] Mapping relationship between RO and SSB;
[0158] Transmission window information of at least one of SSB, PRACH, and RO;
[0159] Send control information using at least one of SSB, PRACH, and RO;
[0160] Control information for the common downlink control channel;
[0161] Instructs the terminal to perform energy-saving operations.
[0162] It should be noted that the terminal performs energy-saving related operations based on the energy-saving information, and network devices can also enter the Network Energy Saving (NES) mode based on the energy-saving information.
[0163] For example, energy-saving information includes SSB period adjustment information, such as increasing or decreasing the SSB period. Taking increasing the SSB period as an example, the terminal's energy-saving operations may include receiving SSBs according to the increased period, and the network device may send SSBs according to the increased period, thereby reducing the power consumption of the network device when sending SSBs.
[0164] For example, energy-saving information includes SSB pattern information. The time-domain window of the SSB indicated by the SSB pattern information in the energy-saving information may be larger or smaller than the time-domain window of the SSB indicated by the SSB pattern information already determined by the terminal. This can involve reducing the SSB period, etc. Taking a smaller time-domain window indicated by the SSB pattern information in the energy-saving information as an example, the terminal's energy-saving related operations may include receiving SSBs according to the SSB pattern information in the energy-saving information, and the network device sending SSBs according to the SSB pattern information in the energy-saving information. Because the SSB time-domain window is smaller, the network device needs to send fewer SSBs, thereby reducing the power consumption of the network device when sending SSBs.
[0165] For example, energy-saving information includes SSB structure information, which includes at least one of the following: the number of SSBs, the beam corresponding to the SSB, and the SSB width. Taking the SSB structure information including the number of SSBs as an example, the number of SSBs in the energy-saving information may be smaller or larger than the number of SSBs already determined by the terminal. For example, if the number of SSBs is smaller, the terminal's energy-saving operations may include receiving SSBs according to the number of SSBs in the energy-saving information, and the network device may send SSBs according to the number of SSBs in the energy-saving information. Therefore, the network device needs to send fewer SSBs, thereby reducing the power consumption of the network device when sending SSBs.
[0166] For example, energy-saving information includes the frequency domain location information of SSBs. The frequency domain spacing of the SSBs indicated by the frequency domain location information in the energy-saving information may be larger or smaller than the frequency domain spacing of the SSBs indicated by the frequency domain location information already determined by the terminal. Taking a larger frequency domain spacing as an example, the terminal's energy-saving related operations may include receiving SSBs according to the frequency domain location information of the SSBs in the energy-saving information, and the network device transmitting SSBs according to the frequency domain location information of the SSBs in the energy-saving information. Because the frequency domain spacing of the SSBs is larger, fewer SSBs are transmitted per unit time, thereby reducing the power consumption of the network device when transmitting SSBs.
[0167] For example, energy-saving information includes the resource period of PRACH. The resource period of PRACH in the energy-saving information may be larger or smaller than the resource period of PRACH already determined by the terminal. Taking a larger resource period as an example, the terminal's energy-saving related operations may include sending PRACH according to the resource period of PRACH in the energy-saving information, and the network device receiving PRACH according to the resource period of PRACH in the energy-saving information. Since the resource period of PRACH is larger, fewer PRACHs need to be received per unit time, thereby reducing the power consumption of the network device in receiving PRACH.
[0168] For example, energy-saving information includes a PRACH resource pattern. The time-domain window of the PRACH indicated by the PRACH resource pattern in the energy-saving information may be larger or smaller than the time-domain window of the PRACH indicated by the resource pattern of the PRACH already determined by the terminal. Taking a smaller time-domain window as an example, the terminal's energy-saving related operations may include sending PRACH according to the PRACH resource pattern in the energy-saving information, and the network device receiving PRACH according to the PRACH resource pattern in the energy-saving information. Because the PRACH time-domain window is smaller, the network device needs to receive fewer PRACHs, thereby reducing the power consumption of the network device when receiving PRACHs.
[0169] For example, energy-saving information includes a mapping relationship between ROs and SSBs. In this mapping, the SSB corresponds to an RO, which is fewer or more than the ROs corresponding to SSBs in the terminal's established RO-SSB mapping. Taking fewer ROs as an example, the terminal's energy-saving operations may include determining the RO according to the RO-SSB mapping in the energy-saving information and sending a random access message on the determined RO. The network device determines the RO according to the RO-SSB mapping in the energy-saving information and receives the random access message on the determined RO. Because there are relatively fewer ROs, the number of random access messages received per unit time is less, thereby reducing the power consumption of the network device in receiving random access messages.
[0170] For example, energy-saving information includes transmission window information for at least one of SSB, PRACH, and RO. The transmission window indicated by the transmission window information in the energy-saving information may be smaller or larger than the transmission window indicated by the transmission window information already determined by the terminal. Taking a smaller transmission window as an example, the terminal performing energy-saving related operations may include receiving an SSB, sending a PRACH, or determining an RO according to the transmission window indicated by the transmission window information in the energy-saving information. The network device sends an SSB, receives a PRACH, or determines an RO according to the transmission window indicated by the transmission window information in the energy-saving information. Since the transmission window is relatively small, fewer SSBs need to be sent, fewer PRACHs need to be received, and fewer ROs need to be determined. Accordingly, the power consumption of the network device when sending an SSB or receiving a PRACH can be reduced.
[0171] For example, energy-saving information includes transmission control information of at least one of SSB, PRACH, and RO. The transmission resources indicated by the transmission control information in the energy-saving information are either sparser or denser than the transmission resources indicated by the transmission control information already determined by the terminal. Taking sparser transmission resources as an example, the terminal's energy-saving related operations may include receiving an SSB, sending a PRACH, or determining an RO according to the transmission resources indicated by the transmission control information in the energy-saving information. The network device sends an SSB, receives a PRACH, or determines an RO according to the transmission window information indicated by the transmission resources in the energy-saving information. Because the transmission resources are relatively sparse, fewer SSBs need to be sent, fewer PRACHs need to be received, and fewer ROs need to be determined. Accordingly, the power consumption of the network device when sending an SSB or receiving a PRACH can be reduced.
[0172] For example, energy-saving information includes control information for the common downlink control channel. The transmission resources indicated by the transmission control information in the energy-saving information are either sparser or denser than the transmission resources indicated by the transmission control information already determined by the terminal. Taking sparser transmission resources as an example, the terminal's energy-saving related operations may include receiving the common downlink control channel according to the transmission resources indicated by the transmission control information in the energy-saving information, and the network device transmitting the common downlink control channel according to the transmission window information indicated by the transmission resources in the energy-saving information. Because the transmission resources are relatively sparse, fewer common downlink control channels need to be transmitted, thereby reducing the power consumption of the network device in transmitting the common downlink control channel.
[0173] For example, energy-saving information may include instructions for the terminal to perform energy-saving operations. The types of energy-saving operations may include at least one of the following: sending, receiving, transmitting, measuring, and reporting. Sending may include Discontinuous Transmission (DTX), and receiving may include DRX. For example, DTX and DRX can be cell-specific. Taking the example of energy-saving information including DRX instructions for the terminal to perform energy-saving operations, the terminal can receive information sent by the network device in a DRX manner, and the network device can send information to the terminal in a DRX manner. Since information does not need to be continuously transmitted in the DRX manner but can be sent discontinuously, it helps reduce the power consumption of the network device when transmitting information.

[0199] Figure 3 is a schematic block diagram illustrating an information receiving device according to an embodiment of the present disclosure. For example, the information receiving device may be disposed in and / or applied to a terminal. As shown in Figure 3, the information receiving device includes: a processing module 301.
[0200] In some embodiments, the processing module is configured to determine the manner of receiving a first downlink control information (DCI) based on predefined rules or indication information from a network device, wherein the first DCI is used to indicate energy-saving information.
