Description

Information sending method, device, terminal, network equipment and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an information sending method, an information sending apparatus, a terminal, a network device, a communication system, and a storage medium. Background Art

[0002] During the communication process between the network device and the terminal, the network device may receive a random access preamble (preamble) sent by the terminal on a resource used by the terminal to send a physical random access channel (Physical Random Access Channel).

[0003] For example, the time domain resource used to send PRACH can be represented by a random access occasion (RO). The terminal can send a preamble to the network device on any available RO. However, the network device does not know which RO the terminal will send the preamble on. To ensure that it can receive the RO sent by the terminal in a timely manner, the network device needs to detect each RO on the PRACH, which will cause significant power consumption to the network device.

[0098] As shown in FIG1 , a 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.

[0099] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

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

[0101] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0102] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0103] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0104] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0105] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0106] The embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0107] In some embodiments, the network device may configure time domain resources for sending a physical random access channel (PRACH) for the terminal. For example, the time domain resources for sending a PRACH may be characterized as a random access occasion (RO).

[0108] The terminal may send a preamble to the network device on any available RO. For example, the terminal may send a preamble to the network device for random access; for example, the terminal may send a preamble to the network device for beam failure recovery (BFR); for example, the terminal may send a preamble to the network device for uplink synchronization; for example, the terminal may send a preamble to the network device for handover (HO). The present disclosure does not limit the reasons why the terminal sends a preamble to the network device.

[0109] Since the network device cannot predict on which ROs the terminal will send the preamble, in order to ensure that the RO sent by the terminal can be received in time, the network device needs to detect each RO on the PRACH, which will cause greater power consumption to the network device.

[0110] FIG2 is an interactive schematic diagram showing a method for sending information according to an embodiment of the present disclosure.

[0111] As shown in FIG2 , the information sending method may include the following steps:

[0112] In step S201, time domain resources for sending a physical random access channel PRACH are determined according to a predefined rule or first indication information sent by a network device.

[0113] In step S202, the terminal may send a PRACH to another terminal in the time domain resources used for sending the PRACH, for example, send a preamble.

[0114] In some embodiments, the network device may configure (for example, through a system information block) a time domain resource for sending a PRACH for the terminal, or the terminal may determine a predefined time domain resource for sending a PRACH, for example, referred to as a first time domain resource (which may be understood as a time domain resource before adjustment). On this basis, the terminal may determine the time domain resource actually used for sending the PRACH, for example, referred to as a second time domain resource, according to a predefined rule or the first indication information of the network device.

[0115] For example, the second time domain resource may be a time domain resource obtained by adjusting the first time domain resource. The relationship between the second time domain resource and the first time domain resource will not be expanded here and will be exemplified in subsequent embodiments.

[0116] In some embodiments, when the terminal determines the second time domain resource for sending PRACH according to a predefined rule, the network device can determine the second time domain resource for the terminal to send PRACH according to the predefined rule, and then receive the preamble sent by the terminal on the second time domain resource.

[0117] In some embodiments, the network device may indicate to the terminal through first indication information the second time domain resource for sending PRACH, the terminal may send a preamble on the second time domain resource indicated by the network device, and the network device may receive the preamble sent by the terminal on the second time domain resource.

[0118] According to an embodiment of the present disclosure, after the network device configures the time domain resources for sending PRACH for the terminal, the terminal can further determine the time domain resources actually used to send the physical random access channel PRACH according to a predefined rule or the first indication information sent by the network device, thereby adjusting the time domain resources configured by the network device for sending PRACH to reduce the time domain resources used to send PRACH per unit time. Then, the network device can detect the preamble sent by the terminal on fewer ROs, thereby saving energy consumption of the network device.

[0119] In some embodiments, the network device may send first indication information to the terminal when it needs to enter a Network Energy Saving (NES) mode or is already in the NES mode.

[0120] In some embodiments, when the network device needs to enter the NES mode or is already in the NES mode, the network device may determine the second time domain resource for the terminal to send the PRACH according to a predefined rule.

[0121] In some embodiments, the first indication information includes at least one of the following:

[0122] Downlink Control Information (DCI);

[0123] Media Access Control Control Element (MAC CE).

[0124] For example, the MAC CE may be carried by a dynamically scheduled physical downlink shared channel (PDSCH), or may be carried by a semi-persistent scheduling (SPD) PDSCH, to which the present disclosure does not limit.

[0125] In some embodiments, the DCI includes at least one of the following: DCI sent via broadcast; group common DCI. Of course, in some embodiments, the DCI may also be DCI sent via unicast.

[0126] In some embodiments, after configuring the first time domain resource for sending the PRACH for the terminal, the network device may adjust the first time domain resource through a system information block (System Information Block, SIB), such as SIB1.

[0127] However, after receiving SIB1 once in a cell, the terminal does not continue to receive SIB1. Instead, it will receive SIB1 again when it determines that it needs to receive SIB1 again. For example, the network device can indicate to the terminal through paging that it needs to receive SIB1 again. Then, the terminal can receive SIB1 again based on the received paging. It can be seen that this method of adjusting the first time domain resources requires the network device to send paging frequently, which still causes a large power consumption overhead for the network device.

[0128] According to an embodiment of the present disclosure, the network device can indicate to the terminal the adjusted second time domain resources for sending PRACH by at least indicating the first indication information in the broadcast DCI, group common DCI, and MAC CE. Since the broadcast DCI, group common DCI, and MAC CE are sent in a targeted manner (for example, for a specific service), they will not be sent frequently, which is beneficial to saving the power consumption overhead of the network device compared to the way the network device adjusts the first time domain resources through SIB1.

[0129] In some embodiments, the DCI sent via broadcast includes at least one of the following:

[0130] DCI format 1_0 scrambled by the System Information-Radio Network Temporary Identifier (SI-RNTI) in the Common Search Space (CSS) of the Type 0 or Type 0A (Type 0 / 0A) Physical Downlink Control Channel (PDCCH);

[0131] In the PDCCH CSS of type 1, DCI format 1_0 is scrambled by the Random Access-Radio Network Temporary Identifier (RA-RNTI);

[0132] In the type 2 PDCCH CSS, the DCI format 1_0 is scrambled by the paging radio network temporary identifier P-RNTI (RA-RNTI).

[0133] In some embodiments, the method further comprises at least one of the following:

[0134] Receive DCI format 1_0 scrambled by P-RNTI according to the paging occasion (PO) agreed upon by the protocol;

[0135] According to the configuration of the PDCCH CSS type 2, DCI format 1_0 scrambled by the P-RNTI is received.

[0136] In some embodiments, for the DCI format 1_0 scrambled by the P-RNTI, the network device may send the DCI format 1_0 scrambled by the P-RNTI to the terminal in a paging occasion agreed upon by the protocol.

[0137] Among them, the terminal can receive DCI at multiple monitor occasions (MOs), and one PO may include some MOs among multiple MOs. The terminal receives DCI format 1_0 scrambled by P-RNTI according to the PO agreed in the protocol, so that the terminal can monitor DCI format 1_0 scrambled by P-RNTI only in some MOs among multiple MOs, without having to monitor DCI format 1_0 scrambled by P-RNTI in all MOs.

[0138] In this case, when the network device needs to send DCI format 1_0 encrypted by P-RNTI to n (n is an integer greater than or equal to 1) terminals, it can send the DCI format 1_0 encrypted by P-RNTI that needs to be sent to the i-th terminal in the MO included in the PO of the i-th terminal among the n terminals.

[0139] In some embodiments, for the DCI format 1_0 scrambled by the P-RNTI, the network device may transmit the DCI format 1_0 scrambled by the P-RNTI according to the configuration of the PDCCH CSS of type 2.

[0140] In this case, when the network device needs to send DCI format 1_0 scrambled by P-RNTI to n terminals, the DCI format 1_0 scrambled by P-RNTI that needs to be sent to the n terminals can be transmitted through the PDCCH CSS of type 2. Then, each of the n terminals can receive the PDCCH CSS of type 2 according to the configuration of the PDCCH CSS of type 2, thereby obtaining the DCI format 1_0 scrambled by P-RNTI transmitted through the PDCCH CSS of type 2.

[0141] In some embodiments, the group-common DCI includes DCI transmitted in a type-3 CSS.

[0142] In some embodiments, the DCI in the Type 3 CSS includes at least one of the following:

[0143] DCI in a new format;

[0144] Traditional DCI 2_x, where x is an integer greater than or equal to 0.

[0145] For example, the communication system may newly define a DCI format, and the newly defined DCI format may be used to carry the above-mentioned first indication information (for example, specifically used to carry the first indication information), instructing the terminal to determine the time domain resources for sending the PRACH.

[0146] For example, the network device can reuse traditional DCI to carry the first indication information, such as multiplexing the DCI of the transmission channel 2 series, that is, DCI 2_x (or writing DCI format 2_x), such as DCI 2_0, DCI 2_1, etc. Because the bits in this series of DCI are convenient for expanding the indication function, it is relatively easy to implement multiplexing this series of DCI to carry indication information.

[0147] In some embodiments, the first indication information includes spare bits in the DCI; or, the first indication information includes all available bits in the DCI.

[0148] For example, when the first indication information is carried by DCI, the idle bits in the DCI can be used as the first indication information.

[0149] For example, when the first indication information is carried by DCI, all available bits in the DCI are used as the first indication information, wherein the available bits in the DCI may include idle bits in the DCI and re-farmed bits in the DCI relative to the traditional information domain. In this case, a specific bit in the DCI (e.g., the Nth bit in the idle bits) can be used to indicate whether the DCI is used to indicate the time domain resources for PRACH to the terminal, for example, the value of the specific bit is 1, indicating that the DCI is used to schedule PDSCH, for example, the value of the specific bit is 0, indicating that the DCI is used to indicate the time domain resources for PRACH to the terminal.

[0150] The following uses several embodiments to illustrate several ways in which the first indication information implements the indication function.

[0151] In some embodiments, the first indication information includes at least one of the following:

[0152] The scaling factor of the PRACH period (e.g., scaling factor);

[0153] Indication information of PRACH configuration.

[0154] In some embodiments, the first indication information may include a scaling factor of the PRACH period, and the scaling factor may indicate the scaling of the PRACH period. For example, the scaling factor may be indicated by k bits, for example, the scaling factor may be implemented in 2 k The 2k scaling factors may be agreed upon by a protocol or indicated by a network device, and the present disclosure does not limit this.

[0155] For example, the terminal can determine the interval of the RO cluster in the time domain according to the Random Access Channel (RACH) configuration, such as the time interval between two radio frames containing RO, which can also be understood as the repetition period of the RO cluster within a radio frame determined according to the RACH configuration.

[0156] For example, the terminal configures a first time domain resource for sending a PRACH for the terminal through SIB1, or a predefined first time domain resource for sending a PRACH. After receiving the first indication information sent by the network device, the terminal determines the scaling factor indicated by the first indication information, and then scales the period of the first time domain resource according to the scaling factor, thereby determining the adjusted second time domain resource.

[0157] For example, if the period of the first time domain resource is T and the scaling factor is m, then the adjusted second time domain resource is T×m, where m can be an integer greater than 1 (in some embodiments, it can also be an integer less than or equal to 1). For example, if the period of the first time domain resource is T=10 milliseconds (ms) and the scaling factor is m=8, then the period of the second time domain resource can be determined to be 80 milliseconds, which means that there are 8 radio frame repetition periods for the RACH configuration, that is, there is an RO cluster determined based on the RACH configuration in every 8 radio frames (e.g., the nth radio frame, the 8nth radio frame, the 16nth radio frame, and so on).

[0158] From this, it can be seen that the second time domain resource determined by the terminal according to the first indication information is more sparsely distributed in the time domain in terms of PRACH compared to the first time domain resource before adjustment, so that the number of PRACHs per unit time is smaller. Therefore, the network device can detect the preamble sent by the terminal on fewer ROs, thereby saving energy consumption of the network device.

[0159] In some embodiments, the first indication information may include indication information of a PRACH configuration (which may be referred to as a RACH configuration). For example, the network device may provide multiple sets of PRACH configurations for the terminal, which may be represented by a list, for example. The multiple sets of configurations may include configurations supported by the current protocol, such as default configurations, and may also include PRACH configurations expanded in the embodiments of the present disclosure.

[0160] Among them, the number of specific configuration items (such as period, time domain resources, beam, frequency domain resources) included in the expanded PRACH configuration in the embodiment of the present disclosure may be the same as the number of specific configuration items in the preset configuration, or the number of specific configuration items included in the expanded PRACH configuration in the embodiment of the present disclosure may be less than the number of specific configuration items in the preset configuration. In this case, the several specific configuration items in the PRACH configuration that are missing from the preset configuration can be determined according to the preset configuration.

[0161] It should be noted that the preset configuration is effective not only for the terminals in the embodiments of the present disclosure, but also for legacy terminals. The terminals in the embodiments of the present disclosure may include terminals that can perform one or more operations in the embodiments of the present disclosure, for example, terminals that support NES. Legacy terminals may be terminals that do not support NES.

[0162] For example, if the network device configures three additional PRACH configurations (e.g., configuration #1, configuration #2, and configuration #3) in addition to the preset configuration, then a PRACH configuration can be indicated to the terminal in the preset configuration and the three newly added PRACH configurations using 2 bits of indication information. For example, a bit value of 00 is used to indicate that the terminal determines the PRACH time domain resources according to the preset configuration, 01 is used to indicate that the terminal determines the PRACH time domain resources according to configuration #1, 10 is used to indicate that the terminal determines the PRACH time domain resources according to configuration #2, and 11 is used to indicate that the terminal determines the PRACH time domain resources according to configuration #3.

[0163] In some embodiments, the indication information may also indicate the PRACH configuration to the terminal through a RACH configuration index, where the RACH configuration index is any one defined in TS38.211.

[0164] It should be noted that the content included in the first indication information is not limited to the above-mentioned PRACH period scaling factor and PRACH configuration indication information, and may also indicate other information, which is not limited in this disclosure.

[0165] For example, the first indication information may also indicate a specific time domain resource configuration (which can be used to determine the second time domain resource), and the time domain resource configuration may include at least one of the following: the time-frequency resource position of the RO (for example, it can be indicated by an RO pattern), the number of available preambles, the period of the PRACH, and the index of the associated synchronization broadcast signal block (Synchronization Signal / PBCH Block, SSB), wherein the index of the SSB can be used to indicate the position and number of ROs that the terminal can send, that is, the terminal only sends PRACH on the RO associated with the indicated SSB index.

[0166] For example, the first indication information may further indicate a persistent window length of the second time domain resource, and the persistent window length may be effective only for configurations other than the preset configuration. The terminal transmits the PRACH based on the second time domain resource within the persistent window, and may revert to transmitting the PRACH using the first time domain resource determined according to the preset configuration outside the persistent window.

[0167] For example, the first indication information may further indicate an effective object, for example, a channel identifier, such as PRACH#1, PRACH#2, etc. The terminal may determine the PRACH applicable to the adjusted second time domain resource according to the channel identifier indicated by the first indication information. For example, if the channel identifier indicated by the first indication information is PRACH#2, the terminal may send PRACH#2 according to the second time domain resource, but still send PRACHs other than PRACH#2 (for example, PRACH#1) according to the first indication resource before adjustment.

[0168] In some embodiments, the terminal may determine the time domain resource for transmitting the PRACH according to a predefined rule, where the predefined rule includes one of the following:

[0169] In response to the network device stopping sending the first information, stopping sending the PRACH to the network device;

[0170] In response to the network device stopping sending the first information, adjusting a period for sending the PRACH to the network device.

[0171] For example, the predefined rule may include stopping sending PRACH to the network device in response to the network device stopping sending the first information. In this case, when the terminal determines that the network device stops sending the first information, it can stop sending PRACH to the network device, and then the PRACH time domain resources can be considered to be completely invalid.

[0172] When the network device stops sending the first information to the terminal, it may also stop receiving the PRACH sent by the terminal, thereby saving energy consumption of the network device.

[0173] For example, the predefined rule may include adjusting a period for sending PRACH to the network device in response to the network device stopping sending the first information. In this case, upon determining that the network device stops sending the first information, the terminal may adjust a period for sending PRACH to the network device, for example, by increasing or decreasing the PRACH period in the first time domain resource, for example, by increasing the PRACH period in the first time domain resource by m times (m is an integer greater than 1).

[0174] When the network device stops sending the first information to the terminal, it can also expand the PRACH period in the first time domain resource and then receive the PRACH according to the expanded PRACH period. In this case, the time domain resources used to send the PRACH per unit time are reduced, thereby helping to save energy consumption of the network device.

[0175] In some embodiments, the first information includes at least one of the following:

[0176] Synchronous advertising signal block SSB;

[0177] System Information Block SIB1.

[0178] It should be noted that the first information is not limited to the above-mentioned SSB and SIB1, and can also be other downlink information, such as reference signals, PDCCH, and PDSCH. Reference signals can include, for example, at least one of the following: Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), etc.

[0179] It should be noted that the predefined rules are not limited to the several situations shown in the above embodiments. For example, they may also include: when the terminal receives the indication information from the network device indicating that it is entering the NES mode, it stops sending PRACH to the network device; when the terminal receives the indication information from the network device indicating that it is entering the NES mode, it adjusts the period of sending PRACH to the network device.

[0180] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.
