Description

Information indication method and communication device

Technical Field

The present application relates to the field of communications, and in particular, to a method and a communication apparatus for information indication.

Background

A low-capability (reduced capability) terminal device (UE) refers to a terminal device that does not have high requirements for service rate and delay, but needs to control cost, that is, a low-capability terminal device does not need to have a strong hardware capability.

The low-capability terminal device may be divided into a terminal device having 1 receiving antenna (abbreviated as 1RUE in this application) and a terminal device having 2 receiving antennas (abbreviated as 2RUE in this application) according to the number of receiving antennas, where 1RUE has a lower coverage than UEs of 2R UE and 4R UE because of the small number of receiving antennas, and 4R UE herein denotes a general terminal device having 4 receiving antennas. As shown in fig. 1, the coverage area of the cell #1 served by the base station is a large outer circle, the coverage area of the 4R UE (i.e., the area capable of normally transmitting data) is a large inner circle, and the coverage area of the 1R UE is a small inner circle. Therefore, if the 1R UE is expected to receive data normally outside the inner real coil and inside the dotted coil as the 4R UE, the base station needs to perform coverage enhancement on the 1R UE.

In one technique, the base station may indicate whether the 1R UE can camp on cell #1 through a System Information Block (SIB) 1. However, in this method, if the base station in fig. 1 is a base station that does not support coverage enhancement, when the base station indicates that 1R UE can camp on cell #1, in this case, if part of 1R UE is located outside the inner solid circle and inside the dashed circle of fig. 1, because the base station does not support coverage enhancement, it may cause that the 1R UE cannot normally receive data after camping; when the base station indicates that no 1R UE can camp on the cell #1, in this case, if part of the 1R UE is located in the inner real circle of fig. 1 (i.e., the center of the cell # 1), the base station is not required to perform coverage enhancement on the 1R UE, and since the base station indicates that no 1R UE can camp on the cell #1, the base station also prohibits the part of the 1R UE from camping on the cell #1, i.e., the 1R UE located in the center of the cell #1 cannot camp on the cell normally.

Disclosure of Invention

The application provides a method and a communication device for information indication, wherein a single UE is used as granularity, the UE can determine whether the network equipment allows the UE to reside or whether the UE can normally receive data or not through an RSRP threshold value, and power consumption and time of the UE can be saved.

In a first aspect, a method for indicating information is provided, where the method for indicating information may be performed by a terminal device, or may also be performed by a chip or a circuit provided in the terminal device.

In the above technical solution, compared to that in fig. 1, the network device that does not support coverage enhancement directly indicates whether a certain type of UE can camp on the first cell, which may result in that the UE that can camp on the cell #1 is indicated to be unable to camp on the cell #1, or that the UE that cannot camp on the cell #1 is unable to normally receive data after camping on the cell, so that the UE that cannot camp on the cell #1 and cannot normally receive data may continue to select a new cell to camp on, which wastes power consumption and time of the UE. According to the scheme provided by the application, a single UE is used as the granularity, the UE can accurately judge whether the UE can reside in the first cell or can normally receive data or not through the RSRP threshold value in the first message, the problem that part of the UE performs cell selection again due to direct indication can be avoided, and the power consumption and the time of the UE are saved.

For a better understanding of the embodiments of the present application, the concepts involved in the embodiments of the present application will be described below.

1. Synchronization signal block (synchronization signal and PBCH block, SSB): the UE includes a primary/secondary synchronization signal and a Physical Broadcast Channel (PBCH), and provides cell downlink synchronization and basic configuration information of a cell for the UE, where the PBCH may carry a Master Information Block (MIB) of the cell, and the MIB may indicate whether SIB1 exists and a location of the SIB 1.

2. Cell barred (Cellbarred): cell barring is a way for the network to control the load, and when the network is heavily loaded, the network can control the UE not to camp on a certain cell. The cell camping indication for the common (legacy) UE, i.e. cellgarred IE, is broadcasted to the UE through the MIB message, but currently, only 1 bit (bit) is left in the MIB to be available, so the cellgarred IE for the low-capability UE can be carried in SIB1 to indicate, and this method can make the base station more flexible indicate whether legacy UE and low-capability UE are allowed to camp on the cell.

It should be understood that when the UE is prohibited from camping during initial cell selection, the UE will not read other SIB messages (SIB 2, 3, 4, etc.), but the parameters for cell reselection are included in these SIB messages, so the UE will not read the parameters for cell reselection to perform cell blind selection.

It should also be understood that when a low-capability UE successfully camps on a certain serving cell and wants to perform handover to a target cell, since the low-capability UE has already successfully camped on the serving cell, the SIB messages (e.g., SIB2, 3, 4, etc.) related to cell reselection can be read, and at this time, the UE can perform cell reselection according to the parameters in the related SIB messages.

3. Information contained in SIB2 to SIB 5:

the SIB2 contains common information related to common frequency, different frequency and/or different system cell reselection;

SIB3 contains the relevant information of adjacent cell only relevant to the reselection of the cells with the same frequency, IE includes cell and blacklist cell with specific reselection parameter;

SIB4 contains information only related to inter-frequency cell reselection, i.e. information of other NR frequencies and inter-frequency neighbors related to cell reselection.

The SIB5 contains information related only to intersystem cell reselection, i.e. information of evolved universal terrestrial radio access (E-UTRA) frequencies and E-UTRA neighboring cells related to cell reselection.

The following describes the method for indicating information proposed in the present application in detail.

Referring to fig. 3, fig. 3 is a schematic flow chart of a method for indicating information according to the present application.

S301, the network device determines a first message indicating whether the UE receiving the first message is allowed to camp on the first cell by whether a Reference Signal Received Power (RSRP) value is included.

When the RSRP threshold is included in the first message, there may be two expressions:

(1) When the first message comprises the RSRP threshold, if the RSRP value of the UE is smaller than the RSRP threshold, the UE is not allowed to reside in the first cell; if the RSRP value of the UE is larger than the RSRP threshold value, the UE is allowed to reside in the first cell; if the RSRP value of the UE is equal to the RSRP threshold, the UE is allowed to reside in the first cell, or the UE is not allowed to reside in the first cell.

(2) When the RSRP threshold is included in the first message, the UE is allowed to camp on the first cell regardless of its RSRP value. If the RSRP value of the UE is smaller than the RSRP threshold value, the UE cannot normally receive data sent by the network equipment; if the RSRP value of the UE is larger than the RSRP threshold value, the UE can normally receive data sent by the network equipment; if the RSRP value of the UE is equal to the RSRP threshold, the UE cannot normally receive the data sent by the network device, or the UE can normally receive the data sent by the network device.

When the RSRP threshold is not included in the first message, it may indicate that the UE is not allowed to camp on the first cell.

Optionally, the first message further includes first indication information, where the first indication information is used to indicate whether the first type terminal device is allowed to camp on the first cell. It should be noted that the UE that determines whether to camp on the first cell according to the RSRP threshold may be understood as a second type terminal device, where the first type terminal device and the second type terminal device are different types of terminal devices. Specifically, the first type terminal device and the second type terminal device are terminal devices with different capabilities. As an example, in this embodiment, the first type terminal device is a 2R UE, and the second type terminal device is a 1R UE.

Optionally, when the first indication information is not included in the first message, the first type terminal device is not allowed to camp on the first cell.

Optionally, the first message is an SIB1 message corresponding to the first cell.

In a possible specific implementation manner, the network device may add a new cellgared IE, such as cellgared-redcap indication (an example of the first indication information), in SIB1 (an example of the first message), to the low-capability UE, to indicate whether the 2R UE is allowed to camp on, and send the cellgared-redcap indication while carrying an RSRP threshold to indicate whether the 1R UE is allowed to camp on or can normally receive data.

It can be seen that, compared with the method of indicating whether 1R UE and 2R UE are allowed to camp respectively through two pieces of indication information, only one piece of indication information is used in the implementation manner, that is, the UE can indicate whether 1R UE and 2R UE are allowed to camp by carrying one RSRP threshold in one piece of indication information, thereby saving signaling overhead.

S302, the network equipment sends a first message.

Optionally, the network device broadcasts the first message to UEs in the first cell.

Correspondingly, the UE receives the first message.

S303, the UE determines whether to be allowed to camp on the first cell according to whether the Reference Signal Received Power (RSRP) threshold is included in the first message.

For whether the UE is allowed to camp on the first cell, see the description in S301, which is not described herein again.

It can be seen that, compared to fig. 1, when the network device that does not support coverage enhancement directly indicates whether a certain type of UE can camp on the first cell, it may cause that the UE that can camp on the cell #1 is indicated to be unable to camp on the cell #1, or cause that the UE that cannot camp on the cell #1 is unable to normally receive data after camping on the cell, so that the UE that cannot camp on the cell #1 and cannot normally receive data continues to select a new cell for camping, which wastes power consumption and time of the UE. According to the scheme provided by the application, a single UE is used as the granularity, the UE can accurately judge whether the UE can reside in the first cell or can normally receive data or not through the RSRP threshold value in the first message, the problem that part of the UE performs cell selection again due to direct indication can be avoided, and therefore power consumption and time of the UE are saved. Meanwhile, compared with a method for indicating whether the 1R UE and the 2R UE are allowed to reside respectively through two pieces of indication information, signaling overhead is saved.

In one implementation, when the UE performs initial cell selection, the UE is not allowed to camp on the first cell, and then the UE performs cell blind selection and reselects another cell to camp on the first cell, as described above, when the UE is prohibited from camping on the initial cell selection, the UE does not read other SIB messages (SIB 2, 3, 4, etc.) but the cell reselection parameters are included in the SIB messages, so the UE does not read the cell reselection parameters and performs cell blind selection. However, the UE may select a cell where the UE is not allowed to camp on, which wastes power consumption and time of the low-capability UE.

In view of this, the present application provides another information indication method, which can reduce the times of blind cell selection of a UE, so that a low-capability UE can find a suitable cell to camp on more quickly.

Referring to fig. 4, fig. 4 is a schematic flow chart of another method for information indication proposed by the present application.

S401, the network device determines a first message, where the first message includes first indication information, and the first indication information is used to indicate one or more second cells that support or do not support the third type of terminal device to camp on, where the second cell is a neighboring cell of the first cell.

Optionally, the third type terminal device may be a 2R UE and/or a 1R UE. When the third type terminal device is a 2R UE, it may be understood that the first indication information is used to indicate one or more second cells supporting or not supporting the 2R UE to camp on; when the third type terminal device is a 1R UE, it may be understood that the first indication information is used to indicate one or more second cells supporting or not supporting the 1R UE to camp on; when the third type terminal devices are 1R UEs and 2R UEs, it can be understood that the first indication information is used to indicate one or more second cells supporting or not supporting 2R UE camping, and at the same time, the first indication information is also used to indicate one or more second cells supporting or not supporting 1R UE camping.

Optionally, when the third type terminal device only indicates a type of terminal device, the first message may further include second indication information, where the second indication information is used to indicate one or more third cells that support or do not support the second type terminal device to camp on, where the third cell is a neighboring cell of the first cell, and the second type terminal device and the third type terminal device are different types of terminal devices. As an example, the third type terminal device is a 2R UE, and the second type terminal device is a 1R UE.

In a possible specific implementation manner, the network device may add a neighbor list (i.e., a case of the first indication information) that supports or does not support the low-capability UE in SIB1 (i.e., a case of the first message).

Optionally, the neighbor list that supports or does not support the low capability UE may be all neighbor lists that support or do not support the low capability UE, or may also be neighbor lists that partially support or do not support the low capability UE.

S402, the network equipment sends a first message.

Optionally, the network device broadcasts the first message to the UE in the first cell.

Correspondingly, the UE receives the first message, wherein the UE is a third type terminal device.

S403, when the UE performs cell switching in the first cell or when the UE is prohibited to reside in the first cell, the UE reselects the cell to reside according to the first indication information.

In another implementation, if the UE is currently and successfully camped in the first cell and is to be handed over to the target cell, when the UE performs cell reselection, since the network device adds the neighboring cell list supporting the UE in the SIB messages (such as SIB2, 3, 4, etc.) related to cell reselection, the UE needs to read all the SIB messages related to cell reselection once to determine which neighboring cells support UE camping, which wastes power consumption and time of the UE.

In view of this, the present application provides another information indication method, which enables the UE to find a suitable cell to camp on more quickly.

Referring to fig. 5, fig. 5 is a schematic flow chart of still another information indication method proposed in the present application.

S501, the network device determines a first message, where the first message includes first indication information, where the first indication information is used to indicate that the UE reads one or more messages in SIB messages related to cell reselection corresponding to a first cell when the first cell performs cell handover or the UE is prohibited to camp on the first cell, and the one or more messages include neighboring cell information supporting the UE.

Optionally, if an intra-frequency neighboring cell supporting the UE exists in the SIB message related to the cell reselection corresponding to the first cell, but an inter-frequency neighboring cell supporting the UE does not exist, the first indication information is used to indicate the UE to read the SIB message including the intra-frequency neighboring cell information supporting the UE corresponding to the first cell. As an example, the first indication information may indicate that the UE only reads SIB2 and/or SIB3 messages, but not other irrelevant SIB messages related to cell reselection, such as SIB 4. It can be understood that the first indication information in this example also indirectly indicates that no inter-frequency neighbor of the first cell supports UE camping.

Optionally, if all SIB messages related to cell reselection corresponding to the first cell include an inter-frequency neighboring cell supporting the UE, but do not include an intra-frequency neighboring cell supporting the UE, the first indication information is used to indicate the UE to read the SIB message including the inter-frequency neighboring cell information supporting the UE corresponding to the first cell. As an example, the first indication information may indicate that the UE only reads SIB2 and/or SIB4 messages, but does not read other unrelated SIB messages related to cell reselection, such as SIB 3. It can be understood that the first indication information in this example also indirectly indicates that none of the intra-frequency neighboring cells of the first cell support UE camping.

In a possible specific implementation manner, the network device may add a new IE, related-SI indication (i.e. an example of the first indication information) to the UE in SIB1 (i.e. an example of the first message), and when the UE performs cell reselection, the UE may read the relevant necessary SIB message according to this IE instead of reading all SIB messages Related to cell reselection.

Optionally, the first message may not include the first indication information, and the following two cases may be indicated:

(1) And indicating that the SIB message related to the cell reselection corresponding to the first cell contains the same-frequency and different-frequency neighboring cell information supporting the UE, and the UE normally reads all SIB messages related to the cell reselection corresponding to the first cell according to the existing flow.

(2) The SIB message which is corresponding to the first cell and is about cell reselection does not contain neighboring cell information supporting UE, and the UE does not need to read the SIB message which is corresponding to the first cell and is about cell reselection.

S502, the network equipment sends a first message.

Illustratively, a network device broadcasts a first message to UEs within a first cell.

Correspondingly, the UE receives the first message.

S503, when the UE performs cell switching in the first cell or when the UE is prohibited to camp in the first cell, the UE reads one or more messages in SIB messages related to cell reselection and corresponding to the first cell according to the first indication information.

Optionally, the first message may not include the first indication information, and how the UE reads the SIB message for cell reselection refers to the description in S501, which is not described herein again.

Optionally, the UE in this embodiment may be a low-capability terminal device, and may also be a common UE, which is not specifically limited in this application.

In the above technical solution, when the UE performs cell handover (or cell reselection), the UE may only read the relevant SIB messages according to the first indication information, and may let the UE read a part of SIB messages less under some conditions instead of reading all SIB messages related to cell reselection once, thereby saving UE power consumption and cell selection time; when the UE performs initial cell selection and is prohibited to reside in the current cell, the UE can read related SIB messages instead of performing cell blind selection without reading all SIB messages, thereby reducing the cell blind selection times, and saving the power consumption of the UE and the cell selection time.

It should be understood that when the network device broadcasts these SIB messages, SIBs with the same transmission period may be mapped into the same or different system messages, and SIBs with different transmission periods cannot be mapped into the same system message. The above scheme may achieve a saving in UE power consumption and cell selection time, i.e. reading one or more SIB messages instead of full reading, when the SIB message transmission periods are different, SIBs 2, 3, 4, 5 may be mapped to different system messages.
