Detailed ways

As described above, in the prior art, the carriers of a cell are divided into multiple carrier sets, different carrier sets correspond to different coverage levels, and the carrier sets corresponding to different coverage levels are fixed. However, as the UE moves, the number of UEs under different coverage levels will change. When the number of UEs with a small coverage level increases, the load will be too heavy, and the carrier set corresponding to the coverage level cannot support so many UEs to camp on.

In the embodiment of the present invention, when the carrier update information issued by the base station is received, the variable carrier member in the updated fixed carrier set is acquired according to the carrier update information. Since the carrier update information is sent by the base station after detecting that the preset conditions are met, the base station can adjust the variable carrier members in the fixed carrier set under the coverage level when the number of user equipments under the coverage level changes, so as to Enables the residency of multiple user equipments.

In order to make the above objects, features and beneficial effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Step S101, delivering carrier configuration information to a user equipment.

In a specific implementation, the base station may configure a fixed carrier set for each coverage level, and configure a common variable carrier set. In the embodiment of the present invention, the common variable carrier set is a carrier set other than the fixed carrier set of each coverage level.

For example, the coverage levels include coverage level 1, coverage level 2, and coverage level 3. A one-to-one corresponding fixed carrier set is configured for coverage level 1, coverage level 2, and coverage level 3, respectively, and a common variable carrier set is configured.

In a specific implementation, the base station may deliver carrier configuration information to the user equipment through a system broadcast message (SIB). The carrier configuration information delivered by the base station to the user equipment may include a fixed carrier set corresponding to each coverage level and a common variable carrier set.

After receiving the system broadcast message sent by the base station, the user equipment can obtain the carrier configuration information configured by the base station, and then determine the carrier member corresponding to the fixed carrier set corresponding to each coverage level and the carrier member corresponding to the variable carrier set. The user equipment determines all carrier members corresponding to the current coverage level according to the carrier members of the fixed carrier set configured by the current coverage level and the paging downlink control information (Paging Downlink Control Information, paging DCI) received under the current coverage level.

Step S102, when it is detected that a preset condition is met, update the variable carrier members allocated in the fixed carrier set, and send carrier update information to the user equipment.

In practical applications, the signal quality of the user equipment will change, so the corresponding coverage level may change accordingly, and the number of user equipments under a certain coverage level will also change accordingly.

In a specific implementation, when the base station detects that the preset condition is met, it can update the variable carrier members allocated in the fixed carrier set, and send carrier update information to the user equipment. After receiving the carrier update information, the user equipment can know that the variable carrier members in the fixed carrier set are updated.

In this embodiment of the present invention, the preset condition may be that the number of user equipments under a certain coverage level changes.

In practical applications, it can be known that Paging DCI is used to schedule paging messages, and the UE receives Paging DCI by periodically monitoring the paging occasion (Paging Occasion, PO) in the idle state. In the current protocol, paging DCI is DCI format 2 scrambled by P-RNTI. When paging DCI is used to indicate Direct Indication information, there will be many bits in Paging DCI that are not used.

In this embodiment of the present invention, when the paging DCI is used to indicate the direct indication information, the base station may send the paging DCI to the user. There are N bits in the paging downlink control information, where N is the number of carrier members in the variable carrier set; the value of the N bits is used to indicate: under the target coverage level corresponding to the carrier carrying the paging downlink control information , whether the carrier members in the variable carrier set are in the fixed carrier set corresponding to the target coverage level.

Under a certain coverage level, if the bit value corresponding to the carrier member in the variable carrier set is 0, it means that the carrier member does not belong to the coverage level; if the bit bit corresponding to the carrier member in the variable carrier set is 0 A value of 1 means that the carrier member belongs to the coverage level.

For example, under coverage level 1, the bit value corresponding to carrier member 1 in the variable carrier set is 1, which means that carrier member 1 belongs to coverage level 1, that is, the user equipment in coverage level 1 can use the carrier member 1.

The carrier allocation method provided in the above embodiments of the present invention will be described below by taking an example.

For example, a cell has a total of 12 subcarriers, which are {C1, C2, C3, C4, C5, C6, C7, C8, C9, C10, C11, C12}, and there are 3 coverage levels {CEL1, CEL2, CEL3} , the fixed carrier set configured for each coverage level of the network is: CEL1{C1, C2}; CEL2{C3, C4}; CEL3{C5, C6}. The variable carrier set includes 6 subcarriers, which are: {C7, C8, C9, C10, C11, C12}.

Since there are 6 carriers in the variable carrier set, there are 6 bits in the Paging DCI for adjustment of the variable carrier set. The value of 6 bits is used to represent the variable carrier members existing on the carrier set corresponding to the corresponding coverage level.

If the bit value corresponding to the paging DCI sent on the carrier set corresponding to coverage level 1 is 010000, it means that the carrier used by coverage level 1 is in addition to the fixed carriers C1 and C2, and also includes the variable carrier C8.

Assume that all carrier members (fixed carrier members and variable carrier members) of each current coverage level are: CEL1{C1, C2, C8}; CEL2{C3, C4, C9, C10}; CEL3{C5, C6, C7, C11 , C12}. Then, the bits corresponding to the Paging DCI sent by the base station on the carrier set corresponding to each coverage level are: CEL1: 010000; CEL2: 001100; CEL3: 100011.

If the base station detects that the number of user equipments corresponding to CEL1 increases, the variable carrier can be adjusted collectively through the 6 bits in the Paging DCI. Specifically, the bit value corresponding to the Paging DCI sent by the base station on the carrier set corresponding to each coverage level is changed to: CEL1: 110000; CEL2: 001100; CEL3: 000011

At this time, the carrier set members corresponding to each coverage level become: CEL1{C1, C2, C7, C8}; CEL2{C3, C4, C9, C10}; CEL3{C5, C6, C11, C12}.

In the embodiment of the present invention, the fixed carrier set refers to: the carrier set includes one or more fixed carriers. The base station may also add variable carriers to the fixed carrier set, or update the variable carriers in the fixed carrier set.

As in the above example, the fixed carrier set corresponding to coverage level 1 includes carrier C1 and carrier C2. The base station may configure the variable carrier C8 in the fixed carrier set corresponding to coverage level 1. In this case, the fixed carrier set corresponding to coverage level 1 includes carrier C1, carrier C2, and carrier C8.

In a specific implementation, the base station may send a paging message (paging message) to the user equipment, and the paging message carries carrier update indication information. Afterwards, the base station may send a system message to the user equipment, where the system message carries carrier update information.

After receiving the paging message, the user equipment can obtain carrier update indication information therefrom, and can know that the variable carrier member in the fixed carrier set has changed. After that, the user equipment obtains the carrier update information from the received system message, so as to know the variable carrier members in the updated fixed carrier set.

In a specific implementation, a specific information element may be newly added in the paging message sent by the base station to the user equipment, and the value of the specific information element indicates whether the variable carrier member in the fixed carrier set corresponding to each coverage level changes.

For example, if the coverage level is 3, a 3-bit specific cell can be added to the paging message, where the first bit is used to indicate whether the variable carrier member in the fixed carrier set corresponding to coverage level 1 has changed, and the second bit The bit is used to indicate whether the variable carrier member in the fixed carrier set corresponding to coverage level 2 has changed; the third bit is used to indicate whether the variable carrier member in the fixed carrier set corresponding to coverage level 3 has changed.

In a specific implementation, the base station may also send paging DCI to the user equipment, and the paging DCI carries carrier update indication information. Afterwards, the base station may send a system message to the user equipment, where the system message carries carrier update information.

After receiving the paging DCI, the user equipment can obtain carrier update indication information from it, and can know that the variable carrier members in the fixed carrier set have changed. After that, the user equipment obtains the carrier update information from the received system message, so as to know the variable carrier members in the updated fixed carrier set.

In a specific implementation, in the paging DCI sent by the base station to the user equipment, a specific cell can be newly added, and the value of the specific cell can be used to represent whether the variable carrier member in the fixed carrier set corresponding to each coverage level has changed.

For example, if the coverage level is 3, a 3-bit specific cell can be added to the paging DCI, where the first bit is used to indicate whether the variable carrier member in the fixed carrier set corresponding to coverage level 1 has changed, and the second bit It is used to indicate whether the variable carrier member in the fixed carrier set corresponding to coverage level 2 has changed; the third bit is used to indicate whether the variable carrier member in the fixed carrier set corresponding to coverage level 3 has changed.

In a specific implementation, the system message delivered by the base station may be an SIB 22-NB message.

In a specific implementation, when the user equipment detects that its corresponding coverage level changes, it needs to report a coverage level change message of the changed coverage level to the base station. After receiving the coverage level change message sent by the user equipment, the base station sends carrier update information corresponding to the changed coverage level to the user equipment.

For example, the coverage level corresponding to the user equipment is transformed from coverage level 2 to coverage level 1. The user equipment sends a coverage level change message to the base station. After receiving the coverage level change message, the base station sends carrier update information corresponding to coverage level 1 to the user equipment to the user equipment.

An embodiment of the present invention further provides another carrier allocation method. Referring to FIG. 2 , the following describes specific steps.

Step S201, receiving carrier configuration information delivered by a base station.

Step S202: Receive carrier update information delivered by the base station.

Step S203: Acquire the updated variable carrier members in the fixed carrier set according to the carrier update information.

Assume that all current carrier members (fixed carrier members and variable carrier members) of each coverage level are: CEL1{C1, C2, C8}; CEL2{C3, C4, C9, C10}; CEL3{C5, C6, C7, C11 , C12}. Then, the bits corresponding to the Paging DCI sent by the base station on the carrier set corresponding to each coverage level are: CEL1: 010000; CEL2: 001100; CEL3: 100011.

For example, the coverage level corresponding to the user equipment is transformed from coverage level 2 to coverage level 1. The user equipment sends a coverage level change message to the base station. After receiving the coverage level change message, the base station sends the carrier update information corresponding to coverage level 1 to the user equipment to the user equipment.
