Description
[ technical field ] A
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a storage medium, and a base station for switching a non-anchor carrier.
[ background ] A method for producing a semiconductor device
In a Narrowband Internet of Things (NB-IoT) network, an anchor carrier is a carrier for transmitting a Narrowband Primary Synchronization Signal (NPSS), a Narrowband Secondary Synchronization Signal (NSSS), a Narrowband Physical Broadcast Channel (NPBCH), and a Narrowband System Information Block Type (SIB-NB), and is used for cell access. Paging messages and random access procedures can only be performed on the anchor carrier. The non-anchor carrier is not used for transmitting the carriers, and the non-anchor carrier is used for data transmission of the carriers, and cannot be used for paging messages and data transmission in a random access process.
Using multi-carrier transmission has the following:
(1) The overhead of the common channel is saved: if only anchor carriers are used, carriers for NPSS, NSSS, NPBCH, and SIB-NB need to be transmitted for each anchor carrier, and thus overhead occupied for the common channel is large, which reduces the capacity of the common channel. When multi-carrier transmission is used, carriers of NPSS, NSSS, NPBCH and SIB-NB do not need to be transmitted on non-anchor carriers, thus reducing the overhead of common channels.
(2) Reducing the number of pilot frequency cells: if only the anchor carrier is used, there may be a large number of inter-frequency cells, which may place a large burden on mobility management of the idle user equipment. With multi-carrier transmission, the number of anchor carriers is greatly reduced, thereby reducing the number of inter-frequency cells.
(3) Reducing power consumption for initial cell selection: by using multi-carrier transmission, the number of anchor carriers is greatly reduced, and cells needing to be measured by the user equipment are reduced, so that the power consumption for selecting the initial cell of the user equipment is reduced;
(4) The method reduces the influence on the performance of a Long Term Evolution (LTE) system In an In-Band deployment mode: in order to ensure the coverage of the cell, the power of the corresponding common channel is usually increased when the carriers of NPSS, NSSS and NPBCH are transmitted. In the In-Band deployment mode, if only the anchor carrier is used, more common channels are subjected to power boosting, which has a great influence on the performance of the LTE system. By using multi-carrier transmission, only part of common channels are subjected to power boosting In the In-Band deployment mode, and compared with the method that only the anchor carrier is used, the influence on the performance of the LTE system In the In-Band deployment mode can be reduced.
In the related art, a triggering mode for switching the user equipment between the anchor carrier and the non-anchor carrier in multi-carrier transmission is defined, but a switching mechanism is not complete after the triggering mode is adopted, so that the success rate of switching between the carriers cannot be ensured, the retransmission rate of the non-anchor carrier may be increased, and further, resource waste is caused.

a first row of the priority matrix comprises the retransmission rate interval, a first column of the priority matrix comprises the utilization interval, and the rest of the priority matrix comprises the priority;
and the priority corresponding to the position of the intersection of the column matrix corresponding to the retransmission rate interval in which the non-anchor carrier retransmission rate is located and the row matrix corresponding to the utilization rate interval in which the anchor carrier utilization rate is located in the priority matrix is the priority of the user equipment.
6. An apparatus for switching a non-anchor carrier, the apparatus comprising:
the acquisition module is used for acquiring a user identifier of user equipment in a cell and acquiring non-anchor carrier data of the user equipment according to the user identifier;
a generating module, configured to generate a non-anchor carrier retransmission rate of the ue according to the non-anchor carrier data;
a determining module, configured to query a priority of the ue according to the non-anchor carrier retransmission rate of the ue and a pre-counted anchor carrier utilization rate; wherein, the lower the retransmission rate of the non-anchor carrier, the higher the priority of the user equipment; the higher the utilization rate of the anchor carrier is, the higher the priority of the user equipment is;
a switching module, configured to sequence the user equipment of the cell according to the priority to generate a priority order of the user equipment, and switch the user equipment to a non-anchor carrier in sequence according to the priority order.
7. The non-anchor carrier switching apparatus according to claim 6, wherein the non-anchor carrier data includes a number of non-anchor carrier retransmissions and a total number of non-anchor carrier transmissions for the user equipment.
8. The non-anchor carrier switching apparatus according to claim 7, wherein the generating module is specifically configured to divide the number of retransmissions of the non-anchor carrier by the total number of transmissions of the non-anchor carrier of the ue, so as to generate the retransmission rate of the non-anchor carrier of the ue.
9. A storage medium, comprising a stored program, wherein the program, when executed, controls an apparatus in which the storage medium is located to perform the non-anchor carrier switching method according to any one of claims 1 to 5.
10. A base station comprising a memory for storing information including program instructions and a processor for controlling the execution of the program instructions, wherein the program instructions are loaded and executed by the processor to implement the steps of the non-anchor carrier switching method according to any one of claims 1 to 5.
