Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information indication method, device and readable storage medium. Background Art

[0002] In order to further save the power consumption of the terminal, the prior art proposes a low power wake-up signal (Low power Wake Up Signal, LP-WUS) signal. When the terminal uses LP-WUS, the main radio frequency (Main Radio, MR) of the terminal can be in a low power state, such as in a closed state. In this way, the terminal can use LP-WUS to perform data reception. Since the power consumption of the terminal using LP-WUR to perform reception is much less than the power consumption of using MR to perform reception, the use of LP-WUS can greatly reduce the power consumption of the terminal.

[0003] In the prior art, there are multiple types of terminals in the same service cell, for example, some terminals support LP-WUS and some terminals do not support LP-WUS. In order to support these two types of terminals, the network side needs to send LP-WUS and reference signals at the same time, which causes the problem of high power consumption on the network side.

[0154] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0155] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0156] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0157] In the prior art, there are multiple types of terminals in the same service cell, for example, some terminals support LP-WUS, while some terminals do not support LP-WUS. In order to support these two types of terminals, the network side needs to send LP-WUS and reference signals such as Paging (paging) / Permanent Equipment Identifier (PEI) / Synchronization Signal / Physical Broadcast Channel Signal Block (Synchronization Signal and PBCH block, SSB) / CSI Reference Signal (CSI Reference Signal, CSI-RS) at the same time. This method will cause high power consumption and resource waste on the network side.

[0158] The embodiments of the present application provide an information indication method and device for reducing power consumption on the network side.

[0159] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0160] See also Figure 1 , Figure 1 is a flowchart of the information indication method provided in an embodiment of the present application, which is applied to a terminal, such as Figure 1 As shown, the following steps are included:

[0161] Step 101: When a first condition is met, first indication information is sent to a network side, wherein the first indication information is used to instruct the terminal to use LP-WUS.

[0162] The first condition includes:

[0163] The signal quality of the SSB or CSI-RS measured by the terminal is greater than a first threshold; or

[0164] The terminal determines to use LP-WUS; or

[0165] The terminal determines to perform cell reselection; or

[0166] The signal quality of the LP-WUS or LP-SS measured by the terminal is greater than a second threshold.

[0167] Among them, the first threshold and the second threshold can be obtained from the network side or pre-set. The terminal determines to use LP-WUS, for example, the terminal determines to use LP-WUS based on information such as terminal capabilities and broadcast messages, or the terminal judges the signal quality of SSB / CSI-RS, and obtains a judgment result that LP-WUS needs to be used. The terminal determines to perform cell reselection, for example, the terminal judges according to the conditions of cell reselection and determines to perform cell reselection. Among them, the conditions for cell reselection may be, for example, that the signal quality of the neighboring cell is greater than the signal quality of the current resident cell (or serving cell). Alternatively, the terminal determines to use LP-WUS, and the terminal may also judge by the signal quality of LP-WUS or LP-SS measured by the terminal, and obtain a judgment result that LP-WUS needs to be used.

[0168] The signal quality of SSB or CSI-RS or LP-WUS or LP-SS can be reflected by reference signal received power (RSRP) / reference signal received quality (RSRQ) / signal-to-noise and interference ratio (SINR) and the like.

[0169] Among them, the terminal using LP-WUS may mean: the terminal uses a low power wakeup receiver (Low power Wakeup receiver, LP-WUR) to receive LP-WUS or LP-SS, or uses LP-WUS for radio resource management (Radioresource management, RRM) measurement, or uses LP-WUS to perform neighboring area measurement, or uses LP-WUS to indicate paging information or PEI information or uses energy-saving RNTI scrambled DCI (DCI with CRC scrambled by PS-RNTI, DCP) information, etc.

[0170] In an embodiment of the present application, when the first condition is met, sending the first indication information to the network side may be specifically: the terminal may send the first indication information to the current resident cell and / or the target neighboring cell when the terminal performs cell reselection; or, when the terminal is in an idle state or an inactive state, send the first indication information to the current resident cell and / or the target neighboring cell through a random access process; or, when the terminal is in a connected state, send the first indication information to the source cell and / or the target cell through a random access process. The target neighboring cell is the cell that the terminal is going to access by performing a cell reselection process, that is, the target neighboring cell is the cell where the terminal re-resides after reselection.

[0171] The first indication information may be sent to the network side in a variety of forms, such as Msg3, Msg5, MSGA message of the random access process, or a newly defined message.

[0172] In an embodiment of the present application, the first indication information includes one or more of the following:

[0173] UE ID;

[0174] Resume ID;

[0175] C-RNTI;

[0176] Current resident cell ID;

[0177] Target neighboring cell identifier;

[0178] Source cell identifier;

[0179] Target cell identifier;

[0180] The first indication is used to instruct the terminal to use LP-WUS.

[0181] Among them, the C-RNTI includes the C-RNTI used when the terminal is in a connected state. The above-mentioned cell identifiers can be, for example, the physical cell identifier (PCI) information of the cell, frequency information, etc. The first indication is carried on any one of the following: Resume cause, Setup cause, IE. For example, Resume cause or Setup cause can be modified to LP, such as LP-WUS. For another example, the IE can be implemented in the form of a 1-bit indication to indicate that the terminal uses LP-WUS.

[0182] In the embodiment of the present application, the terminal sends the first indication information to the network side to instruct the terminal to use LP-WUS. Therefore, the network side can send a signal in a targeted manner according to the first indication information of the terminal, thereby reducing the power consumption of the network side and avoiding the problem of resource waste.

[0183] Optionally, in the embodiment of the present application, the terminal may also receive LP-WUS configuration information sent by the network side. Then, correspondingly, in step 101, when the terminal determines that the first condition is met according to the LP-WUS configuration information, the terminal sends first indication information to the network side.

[0184] The LP-WUS configuration information includes one or more of the following:

[0185] UE ID or Cell ID corresponding to LP-WUS;

[0186] The cycle of LP-WUS;

[0187] Resource location information of LP-WUS;

[0188] Conditions for using LP-WUS: If the signal quality of SSB or CSI-RS measured by the terminal is greater than a first threshold, the terminal uses LP-WUS; if the signal quality of LP-WUS or LP-SS measured by the terminal is greater than a second threshold, the terminal uses LP-WUS;

[0189] Conditions for stopping the use of LP-WUS: if the signal quality of LP-WUS or LP-SS measured by the terminal is less than (or less than or equal to) the second threshold, the terminal stops using LP-WUS; if the signal quality of SSB or CSI-RS measured by the terminal is less than (or less than or equal to) the first threshold, the terminal stops using LP-WUS;

[0190] First threshold;

[0191] The second threshold.

[0192] The first threshold and the second threshold can be set as needed.

[0193] The first threshold is used to determine whether the terminal uses LP-WUS according to the signal quality of the SSB or CSI-RS measured by the terminal. For example, if the signal quality of the SSB or CSI-RS measured by the terminal is greater than the first threshold, the terminal uses LP-WUS; if the signal quality of the SSB or CSI-RS measured by the terminal is less than the first threshold, the terminal stops using LP-WUS.

[0194] The second threshold is used to determine whether the terminal stops using the LP-WUS according to the signal quality of the LP-WUS or LP-SS measured by the terminal. For example, if the signal quality of the LP-WUS or LP-SS measured by the terminal is less than the second threshold, the terminal stops using the LP-WUS; if the signal quality of the LP-WUS or LP-SS measured by the terminal is greater than the second threshold, the terminal uses the LP-WUS.

[0195] See also Figure 2 , Figure 2 1 is a flowchart of the information indication method provided by the embodiment of the present application, which is applied to the network side. The network side includes the target cell, the source cell, the target neighboring cell, the current resident cell, etc. Figure 2 As shown, the following steps are included:

[0196] Step 201: Receive first indication information sent by a terminal, wherein the first indication information is used to instruct the terminal to use LP-WUS.

[0197] The meaning and explanation of the first indication information may refer to the description of the aforementioned method embodiment.

[0198] Step 202: According to the first indication information, use LP-WUS to send data to the terminal.

[0199] In the embodiment of the present application, the terminal sends the first indication information to the network side to instruct the terminal to use LP-WUS. Therefore, the network side can send a signal in a targeted manner according to the first indication information of the terminal, thereby reducing the power consumption of the network side and avoiding the problem of resource waste.

[0200] Optionally, in the embodiment of the present application, the network side may also send LP-WUS configuration information to the terminal. The LP-WUS configuration information includes one or more of the following:

[0201] UE ID or Cell ID corresponding to LP-WUS;

[0202] The cycle of LP-WUS;

[0203] Resource location information of LP-WUS;

[0204] Conditions for using LP-WUS;

[0205] Conditions for discontinuing the use of LP-WUS;

[0206] First threshold;

[0207] The second threshold.

[0208] For the meaning and interpretation of the LP-WUS configuration information, reference may be made to the description of the aforementioned method embodiment.

[0209] Optionally, the network side may also send a second indication message to a neighboring cell (such as a target neighboring cell), wherein the second indication message is used to instruct the terminal to use LP-WUS. In this way, after the terminal performs cell reselection, it is not necessary to send the first indication message to the original resident cell.

[0210] In one embodiment of the present application, within the same serving cell, the terminal indicates to the network side that the terminal uses LP-WUS. Figure 3 As shown, the process may include:

[0211] Step 301: The network sends LP-WUS configuration information to the terminal.

[0212] Optionally, the LP-WUS configuration information may be carried via a broadcast message or an RRCRelease (RRC connection release) or an RRC reconfiguration message.

[0213] Optionally, the LP-WUS configuration information may include one or more configuration information.

[0214] Optionally, the LP-WUS configuration information may include one or more of the following:

[0215] UE ID or Cell ID corresponding to LP-WUS;

[0216] The cycle of LP-WUS;

[0217] Resource location information of LP-WUS;

[0218] Conditions for using LP-WUS (or conditions for entering LP-WUS);

[0219] Conditions for ceasing to use LP-WUS (or conditions for leaving LP-WUS);

[0220] A first threshold, used to indicate that the terminal uses LP-WUS when the signal quality of the SSB or CSI-RS measured by the terminal is greater than the first threshold; or, to indicate that the terminal stops using LP-WUS when the signal quality of the SSB or CSI-RS measured by the terminal is less than the first threshold;

[0221] A first duration is used to indicate that when the signal quality of the SSB or CSI-RS measured by the terminal is greater than the first threshold and satisfies the first duration, the terminal uses the LP-WUS; or, when the signal quality of the SSB or CSI-RS measured by the terminal is less than the first threshold and satisfies the first duration, the terminal stops using the LP-WUS; or, when the signal quality of the LP-WUS or LP-SS measured by the terminal is greater than the second threshold, the terminal stops using the LP-WUS;

[0222] A second threshold, used to indicate that the terminal stops using the LP-WUS when the signal quality of the LP-WUS or LP-SS measured by the terminal is less than the second threshold;

[0223] Correspondingly, the terminal receives the LP-WUS configuration information sent by the network side.

[0224] Step 302: The terminal determines whether the conditions for using LP-WUS are met.

[0225] Optionally, the terminal determines the signal strength of the measured SSB or CSI-RS, for example, the terminal determines whether RSRP or RSRQ or SINR is greater than a first threshold. The RSRP or RSRQ or SINR here can be the RSRP or RSRQ or SINR value obtained by measuring the synchronization signal / physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB) / CSI reference signal (CSI ReferenceSignal, CSI-RS).

[0226] If RSRP or RSRQ or SINR is greater than the first threshold, optionally, the RSRP or RSRQ or SINR measured within the first time length is greater than the first threshold, then the terminal is considered to meet the conditions for using LP-WUS. For example, if the RSRP of the SSB measured by the terminal is greater than the first threshold within the first time length, then the terminal is considered to meet the conditions for using LP-WUS.

[0227] Step 303: The terminal sends first instruction information to the network side, instructing the terminal to use LP-WUS.

[0228] Optionally, the terminal sends first indication information to the network side, where the first indication information includes one or more of the following: UE ID or Resume ID or C-RNTI, and indication information that the terminal uses LP-WUS.

[0229] For example, one bit is added to RRCResumeRequest (RRC resume request), and the one bit indicates that the terminal uses LP-WUS. Alternatively, resumeCause in RRCResumeRequest is modified to LP-WUS. Alternatively, EstablishmentCause in RRCSetRequest is modified to LP-WUS. Alternatively, a new message may be defined in an embodiment of the present application, such as LP-WUS indication information, to indicate that the terminal uses LP-WUS.

[0230] Optionally, the terminal may also instruct the network side to use LP-WUS by triggering a random access process. For example, the random access process may be a 4-step RACH (4-step random access process) or a 2-step RACH (2-step random access process).

[0231] If the terminal triggers 4-step RACH, the terminal may send the first indication information to the network side in Msg3 or Msg5; if 2-step RACH is triggered, the terminal may send the first indication information to the network side in MSGA;

[0232] Step 304: After receiving the first indication information sent by the terminal, the network side stops sending data to the terminal using Paging, PEI or DCP, and uses LP-WUS to send data.

[0233] Optionally, the network side sends second indication information to multiple neighboring cells to instruct the terminal to use LP-WUS.

[0234] In one embodiment of the present application, when performing cell reselection, the terminal indicates to the network side that the terminal uses LP-WUS. Figure 4 As shown, the process may include:

[0235] Step 401: The network sends LP-WUS configuration information to the terminal.

[0236] Optionally, the LP-WUS configuration information may be carried via a broadcast message or an RRCRelease (RRC connection release) or an RRC reconfiguration message.

[0237] Optionally, the LP-WUS configuration information may include one or more configuration information.

[0238] Optionally, the LP-WUS configuration information may include one or more of the following:

[0239] UE ID or Cell ID corresponding to LP-WUS;

[0240] The cycle of LP-WUS;

[0241] Resource location information of LP-WUS;

[0242] Conditions for using LP-WUS (or conditions for entering LP-WUS);

[0243] Conditions for ceasing to use LP-WUS (or conditions for leaving LP-WUS);

[0244] A first threshold, used to indicate that the terminal uses LP-WUS when the signal quality of the SSB or CSI-RS measured by the terminal is greater than the first threshold; or, to indicate that the terminal stops using LP-WUS when the signal quality of the SSB or CSI-RS measured by the terminal is less than the first threshold;

[0245] A first duration, used to indicate that the terminal uses LP-WUS when the signal quality of the SSB or CSI-RS measured by the terminal is greater than the first threshold and satisfies the first duration; or, to indicate that the terminal stops using LP-WUS when the signal quality of the SSB or CSI-RS measured by the terminal is less than the first threshold and satisfies the first duration;

[0246] a second threshold, used to indicate that when the signal quality of the LP-WUS or LP-SS measured by the terminal is less than the second threshold, the terminal stops using the LP-WUS; or, when the signal quality of the LP-WUS or LP-SS measured by the terminal is greater than the second threshold, the terminal stops using the LP-WUS;

[0247] Correspondingly, the terminal receives the LP-WUS configuration information sent by the network side.

[0248] Step 402: The terminal determines whether a cell reselection condition is met.

[0249] Specifically, for example, when the signal quality of the neighboring cell is better than the signal quality of the serving cell, it can be considered that the cell reselection condition is met.

[0250] After the terminal determines that the cell reselection conditions are met, it can perform one or more of the following processes:

[0251] Step 402A. The terminal sends a first indication message to the currently resident cell;

[0252] Step 402B: The terminal sends first indication information to the target neighboring cell.

[0253] Wherein, step 402A may include:

[0254] The terminal evaluates the cell reselection criteria, and when a neighboring cell is found to meet the cell reselection criteria, the terminal triggers a random access process. Optionally, the random access process triggered by the terminal can be 4-step RACH or 2-step RACH.

[0255] If it is 4-step RACH, the terminal sends the first indication information to the current resident cell in Msg3 or Msg5; if it is 2-step RACH, the terminal sends the first indication information to the current resident cell in MSGA;

[0256] Optionally, the first indication information sent by the terminal to the currently resident cell includes one or more of the following: UE ID, resume ID, C-RNTI, indication information of the terminal using LP-WUS, target neighboring cell ID (identification), etc. The indication information of the terminal using LP-WUS can be one-bit indication information, or carried by information such as Resume cause / Setup cause, and the target neighboring cell ID information can be PCI information, frequency information, etc. of the target neighboring cell.

[0257] After receiving the first indication information sent by the terminal, the current resident cell sends second indication information to the target neighboring cell, so as to instruct the terminal to use LP-WUS.

[0258] Wherein, step 402B may include:

[0259] The terminal evaluates the cell reselection criteria. When a neighboring cell is found to meet the cell reselection criteria, the terminal reselects to the target neighboring cell and triggers random access in the target neighboring cell. Optionally, the random access process triggered by the terminal can be 4-step RACH or 2-step RACH.

[0260] If it is a 4-step RACH, the terminal sends the first indication information to the target neighboring cell in Msg3 or Msg5; if it is a 2-step RACH, the terminal sends the first indication information to the target neighboring cell in MSGA.

[0261] Optionally, the first indication information sent by the terminal to the target neighboring cell includes one or more of the following: UE ID, resume ID, C-RNTI, indication information that the terminal uses LP-WUS, and target neighboring cell ID information. The indication information that the terminal uses LP-WUS can be a one-bit indication information, or can be carried by information such as Resume cause / Setup cause. The target neighboring cell ID information can be PCI information, frequency information, etc. of the target neighboring cell.

[0262] After receiving the first indication information sent by the terminal, the target neighboring cell sends second indication information to the source cell to instruct the terminal to use LP-WUS in the target neighboring cell, that is, the current resident cell can stop sending data to the terminal using LP-WUS.

[0263] It can be seen from the above description that, by using the solution of the embodiment of the present application, the network side can reduce the sending of Paging or PEI signals according to the first indication information of the terminal, thereby reducing the power consumption of the network side and avoiding waste of resources.
