Description
Technical Field
The invention relates to the technical field of transmission, in particular to a method for sending and receiving system information of co-station multi-cell, an evolution base station and user equipment.
Background
In a later version (referred to as LTE-Advanced) of the Third Generation Partnership Project (3 GPP) Long Term Evolution (LTE) technology, many new technologies are introduced, and carrier aggregation technology is also introduced as a key technology to support higher bandwidth transmission. The basic principle of carrier aggregation is to work by aggregating two or more basic carriers together to meet higher bandwidth requirements. Fig. 1-1 is a scenario in which the system does not use the carrier aggregation technique, and fig. 1-2 is a scenario in which the system uses the carrier aggregation technique. After the carrier aggregation technology is introduced, the number of carriers in a base station cell is changed from 1 to a plurality of carriers, thereby bringing new challenges to the transmission and reception of system information.
The cell system information refers to information necessary for a user to camp on a cell, reselect the cell, and initiate and receive various services. The cell system information is carried over the downlink carrier of the cell. The cell system information consists of a primary system information block and system information blocks 1-12. After the carrier aggregation technology is introduced, multi-carrier will bring a multi-cell scenario, i.e. co-sited multi-cell. The cells have their own downlink carriers, and the system information is carried on the respective downlink carriers. The system information for these different cells is, some, the same and some different. For example, the primary system information, system information blocks 1 and 2 are different for each cell, while the system information blocks 3-12 are likely to be the same.
Fig. 2 is a flow chart of sending and receiving information of a conventional cell system, as shown in fig. 2, the specific steps are as follows:
step 201: an evolved Node Base (eNB) selects a cell not configured with system information from the co-sited multi-cells.
Step 202: and the eNB allocates resources for bearing system information on the downlink carrier of the cell.
The resource allocation scheme is determined by the scheduler.
Step 203: the eNB calculates a binary Value by using a preset algorithm according to the position and the number of the allocated resources, and the binary Value is called as a Resource Indication Value (RIV).
The RIV can uniquely identify the location and number of allocated resources, i.e., the location and number of any kind of resource will map to a unique binary number.
Step 204: the eNB puts the RIV into a downlink control channel of the cell, and adds a System Information-Radio Network Temporary identity (SI-RNTI) to a cyclic redundancy detection bit of the downlink control channel to identify a resource occupied by the downlink control channel for indicating System Information.
Step 205: the eNB carries system information on the downlink carrier of the cell according to the allocated resources.
Step 206: the eNB performs the system information configuration process of other cells of the current co-sited multi-cell again according to step 201 and 205 until all cells complete the system information configuration.
Step 207: when User Equipment (UE) needs to receive system information of a cell, all downlink control channels of the cell are detected, when the fact that the cyclic redundancy detection bit of the downlink control channel has SI-RNTI is detected, the RIV in the downlink control channels is read, and resources used for bearing the system information on downlink carriers of the cell are calculated according to the RIV.
Step 208: and the UE receives the system information of the cell on the resource according to the calculated resource.
The disadvantages of the above method are: when the UE needs to acquire the system information of multiple cells, it needs to detect the downlink control channels of the multiple cells, and then can receive the system information of each cell on different resources according to the RIV in the downlink control channel, so as to increase the detection times of the downlink control channel by the UE, thereby increasing the processing burden of the UE. Moreover, when the carrier aggregation technique is adopted, if the channel state on some carriers becomes poor and the reliability is reduced, the UE cannot correctly analyze the mask on the carriers, so that the system information cannot be received.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 3 is a flowchart of a method for transmitting and receiving cell system information in a co-sited multi-cell according to the present invention, as shown in fig. 3, the specific steps are as follows:
step 300: for each downlink carrier in the co-sited multi-cell, an association relation is established among physical layer resources used for bearing system information on each downlink carrier.
The purpose of establishing the association is such that: the resource information for carrying the system information on other downlink carriers can be deduced from the resource information for carrying the system information on any downlink carrier of the co-sited multi-cell.
Here, the resource information generally refers to the number of physical layer resources and the location of a starting resource block.
Step 301: and when the eNB needs to send the system information, allocating physical layer resources for bearing the system information on downlink carriers of all cells of the co-sited multi-cell according to the established association relation.
Step 302: and the eNB puts the resource information distributed for each cell into a downlink control channel of the corresponding cell, and marks the downlink control channel to be used for indicating the physical layer resources occupied by the system information.
Step 303: the eNB carries system information on the downlink carrier of each cell according to the allocated resources.
Step 304: when UE needs to receive system information, a cell is selected, a downlink control channel of the cell is detected, and when the downlink control channel is detected to be used for indicating physical layer resources occupied by the system information, resource information used for bearing the system information on a downlink carrier of the cell is obtained from the downlink control channel.
Here, the UE may arbitrarily select one cell. Preferably, a cell with higher channel reliability may be selected.
Step 305: the UE obtains the physical layer resource for carrying the system information on the downlink carrier of each cell of the co-sited multi-cell according to the obtained resource information and the association relationship established in step 300, and receives the system information of each cell on each resource according to the obtained resource.
Four specific embodiments are given below according to the difference of the association relationship established between the resources for carrying the system information on the downlink carriers of the co-sited multi-cell:
fig. 4 is a flowchart of a method for sending and receiving cell system information in a co-sited multi-cell according to an embodiment of the present invention, and as shown in fig. 4, the specific steps are as follows:
step 400: the eNB sets the RIV corresponding to the physical layer resource for bearing the system information to be the same for all downlink carriers of the co-sited multi-cell.
Step 401: and the eNB carries out time synchronization and subframe synchronization on downlink carriers of all cells in the co-sited multi-cell.
Subframe synchronization is to allow all cells to transmit system information on the same subframe.
Step 402: when the system information needs to be carried in one subframe, the eNB selects a cell with the minimum downlink carrier bandwidth as a preferred cell in the co-sited multi-cell.
If the downlink carrier bandwidths of more than two cells are minimum, one of the more than two cells can be arbitrarily selected as a preferred cell; or, further selected according to other rules, such as: and selecting the cell with the largest difference of channel transmission conditions among the physical layer resources of the downlink carrier as the preferred cell.
Step 403: and the eNB allocates physical layer resources for bearing system information on the downlink carrier of the preferred cell.
The resource allocation scheme is the same as the prior art.
Step 404: the eNB calculates one RIV according to the allocated physical layer resources.
The calculation formula for RIV can be as follows:

Step 405: the eNB puts the RIV into a resource block allocation (resource block allocation) field in Downlink Control Information (DCI) of a Downlink Control Information of the preferred cell, and adds SI-RNTI to a cyclic redundancy detection bit of the Downlink Control channel to identify that the Downlink Control channel is used for indicating physical layer resources occupied by system Information.
Step 406: and the eNB carries the system information on the downlink carrier of the preferred cell according to the allocated physical layer resource.
Step 407: and the eNB selects a cell without system information in the current co-sited multi-cell, calculates the physical layer resource represented by the RIV value in the downlink carrier wave of the current cell according to the RIV value of the preferred cell, and transmits the system information of the current cell according to the calculated resource.
Step 408: the eNB puts the RIV into a resource block allocation field in DCI of a downlink control channel of the current cell, and adds SI-RNTI on a cyclic redundancy detection bit of the downlink control channel to mark the physical layer resource occupied by the downlink control channel for indicating system information.
Step 409: the eNB performs the system information configuration process of other cells of the current co-sited multi-cell again according to the steps 407 and 408 until all the cells in the current co-sited multi-cell complete the system information configuration.
Step 410: when UE needs to receive system information, a cell is selected, a downlink control channel of the cell is detected, and when the cyclic redundancy detection bit of the downlink control channel is detected to have SI-RNTI, the resource block allocation field value of the downlink control channel, namely RIV, is read.
Step 411: and the UE calculates physical layer resources for bearing system information on downlink carriers of all the cells of the co-sited multi-cell according to the RIV, and receives the system information of the corresponding cell on all the resources according to the calculated physical layer resources.
As can be seen from the embodiment shown in fig. 4, the RIVs of all cells of the co-sited multi-cell are the same, so that when the UE acquires the RIV from the downlink control channel of one cell, the physical layer resources for carrying system information on the downlink carriers of all cells can be obtained according to the RIV.
Fig. 5 is a flowchart of a method for sending and receiving cell system information in a co-sited multi-cell according to a second embodiment of the present invention, and as shown in fig. 5, the specific steps are as follows:
step 500: eNB setting: in a co-sited multi-cell, time domain resources used for bearing system information on each downlink carrier are the same; the positions of the frequency domain resources used for bearing the system information on the downlink carriers are the same.
The position in this step may be an absolute position or a relative position. The absolute position may be, for example, a number of the frequency domain resource used for carrying the system information on each downlink carrier on the downlink carrier where the frequency domain resource is located.
When the position is a relative position, the same position of the frequency domain resource for carrying the system information on each downlink carrier on the downlink carrier where the frequency domain resource is located may be: the distances from a first reference point on the frequency domain resource used for bearing the system information on each downlink carrier to a second reference point on the downlink carrier where the first reference point is located are the same; or the distances from the first reference point on the frequency domain resource for bearing the system information on each downlink carrier to the third reference point in the reference sub-band on the downlink carrier where the first reference point is located are the same. Here, the reference subbands are: dividing each downlink carrier into more than one sub-band according to a preset bandwidth, and selecting one sub-band as a reference sub-band, for example: the first subband or the last subband is selected as the reference subband.
The first reference point may be a frequency point on each frequency domain resource, where the position of the frequency point can be described specifically, the second reference point may be a frequency point on each downlink carrier, where the position of the frequency point can be described specifically, and the third reference point may be a frequency point in a reference subband on the downlink carrier, where the position of the frequency point can be described specifically.
The first reference point may be a starting frequency point, a central frequency point, a terminating frequency point, etc. of the frequency domain resource; the second reference point may be an initial frequency point, a central frequency point, or a termination frequency point of the downlink carrier, or a frequency point whose distance to one of the initial frequency point, the central frequency point, or the termination frequency point of the downlink carrier is a preset distance, and the like, where the preset distance may be determined based on a bandwidth of the downlink carrier, for example: is a% (0 < a < 100) of the bandwidth of the downlink carrier wave; the third reference point may be a start frequency point, a center frequency point, or an end frequency point of the reference subband, or a frequency point whose distance to one of the start frequency point, the center frequency point, or the end frequency point of the reference subband is a preset distance, and so on. Taking the first reference point as the initial frequency point of the frequency domain resource on the downlink carrier, and the second reference point as the central frequency point of the downlink carrier as an example, at this time, in the frequency domain resource for carrying the system information on each downlink carrier, the distance from the initial frequency point of each frequency domain resource on the downlink carrier where the frequency domain resource is located to the central frequency point of the downlink carrier where the frequency domain resource is located is the same, and at this time, when the distance is half of the bandwidth occupied by the system information, the frequency domain resource is exactly located at the central position of the downlink carrier where the frequency domain resource is located.
Step 501: and the eNB carries out time synchronization and subframe synchronization on downlink carriers of all cells in the co-sited multi-cell.
Step 502: when system information needs to be carried in one subframe, the eNB selects one cell as a preferred cell in the co-sited multi-cell.
Here, a cell may be arbitrarily selected as the preferred cell, or a cell may be selected as the preferred cell according to a preset rule, for example: and selecting the cell with the minimum downlink carrier bandwidth or selecting the cell with the minimum downlink carrier frequency point.
Step 503: and the eNB allocates physical layer resources for bearing system information on the downlink carrier of the preferred cell.
The resource allocation scheme is the same as the prior art.
Step 504: the eNB calculates one RIV according to the allocated physical layer resources.
The calculation formula for RIV is the same as step 404.
Step 505: and the eNB puts the RIV into a resource block allocation field in DCI of a downlink control channel of the preferred cell, and adds SI-RNTI to a cyclic redundancy detection bit of the downlink control channel so as to mark the physical layer resource occupied by the downlink control channel for indicating system information.
Step 506: and the eNB carries the system information on the downlink carrier of the preferred cell according to the allocated resources.
Step 507: and the eNB selects a cell without system information in the current co-sited multi-cell.
Step 508: the eNB sets the time domain resource used for bearing the system information on the downlink carrier wave of the current cell to be the same as the preferred cell, and sets the position of the frequency domain resource used for bearing the system information on the downlink carrier wave of the current cell to be the same as the preferred cell.
Step 509: and the eNB calculates the RIV according to the physical layer resource used for bearing the system information on the downlink carrier wave of the current cell.
Step 510: the eNB puts the RIV into a resource block allocation field in DCI of a downlink control channel of the current cell, and adds SI-RNTI on a cyclic redundancy detection bit of the downlink control channel to mark the physical layer resource occupied by the downlink control channel for indicating system information.
Step 511: and the eNB carries the system information on the downlink carrier wave of the current cell according to the allocated physical layer resource.
Step 512: the eNB performs the system information configuration process of other cells in the current co-sited multi-cell again according to the step 507 and 511 until all the cells in the current co-sited multi-cell complete the system information configuration.
Step 513: when UE needs to receive system information, a cell is selected, a downlink control channel of the cell is detected, and when the cyclic redundancy detection bit of the downlink control channel is detected to have SI-RNTI, the resource block allocation field value of the downlink control channel, namely RIV, is read.
Step 514: and the UE calculates the physical layer resources used for bearing the system information on the downlink carrier wave of the cell according to the RIV, and obtains the physical layer resources used for bearing the system information on the downlink carrier waves of other cells according to the calculated physical layer resources.
Step 515: and the UE receives the system information of each cell on the physical layer resource which is used for bearing the system information on the downlink carrier wave of each cell.
Fig. 6 is a flowchart of a method for sending and receiving cell system information in a co-sited multi-cell according to a third embodiment of the present invention, and as shown in fig. 6, the specific steps are as follows:
step 600: the eNB sets the RIV corresponding to the physical layer resources for bearing the system information of all downlink carriers of the co-sited multi-cell to be the same, and sets the RIV value in advance.
The preset RIV value can be determined according to the length of the system information, the bandwidth of each downlink carrier and the channel state of each cell, as long as the requirement that the system information can be carried on each downlink carrier is met.
Step 601: and the eNB carries out time synchronization and subframe synchronization on downlink carriers of all cells in the co-sited multi-cell.
Step 602: when the system information needs to be carried in one subframe, the eNB selects a cell without the system information in the current co-sited multi-cell.
Step 603: and the eNB calculates the physical layer resource represented by the RIV value in the downlink carrier of the current cell according to the preset RIV value.
Step 604: and the eNB bears the system information of the current cell on the downlink carrier wave of the current cell according to the calculated physical layer resources.
Step 605: the eNB puts the RIV into a resource block allocation field in DCI of a downlink control channel of the current cell, and adds SI-RNTI on a cyclic redundancy detection bit of the downlink control channel to mark the physical layer resource occupied by the downlink control channel for indicating system information.
Step 606: the eNB performs the system information configuration process of other cells of the current co-located multi-cell again according to step 602-605 until all the cells in the current co-located multi-cell complete the system information configuration.
Step 607: when UE needs to receive system information, a cell is selected, a downlink control channel of the cell is detected, and when the cyclic redundancy detection bit of the downlink control channel is detected to have SI-RNTI, the resource block allocation field value of the downlink control channel, namely RIV, is read.
Step 608: and the UE calculates physical layer resources for bearing system information on downlink carriers of all the cells of the co-sited multi-cell according to the RIV, and receives the system information of the corresponding cell on all the resources according to the calculated physical layer resources.
Fig. 7 is a flowchart of a method for sending and receiving cell system information in a co-sited multi-cell according to a fourth embodiment of the present invention, as shown in fig. 7, the specific steps are as follows:
step 700: the eNB sets a reference resource on a reference downlink carrier in advance and calculates the RIV of the reference resource; and setting: in the co-sited multi-cell, the time domain resource used for bearing the system information on each downlink carrier is the same as the time domain resource of the reference resource; the position of the frequency domain resource used for bearing the system information on each downlink carrier on the downlink carrier is the same as the position of the frequency domain resource of the reference resource on the reference downlink carrier.
Here, the reference downlink carrier and the reference resource may be determined according to the length of the system information, the bandwidth of each downlink carrier of the co-sited multi-cell, and the channel state of each cell, as long as the system information can be borne on each downlink carrier of the co-sited multi-cell.
The position in this step may be an absolute position or a relative position. The absolute position may be, for example, a number of the frequency domain resource used for carrying the system information on each downlink carrier on the downlink carrier where the frequency domain resource is located.
When the position is a relative position, the position of the frequency domain resource for carrying the system information on each downlink carrier on the downlink carrier where the frequency domain resource is located is the same as the position of the frequency domain resource of the reference resource on the reference downlink carrier may be: the distance from a first reference point on the frequency domain resource used for bearing the system information on each downlink carrier to a preset second reference point on the downlink carrier where the first reference point is located is the same as the distance from the first reference point on the frequency domain resource of the reference resource to the second reference point on the reference downlink carrier; or the distances from the first reference point on the frequency domain resource for bearing the system information on each downlink carrier to the third reference point in the reference sub-band on the downlink carrier where the first reference point is located are the same. Here, the reference subbands are: dividing each downlink carrier into more than one sub-band according to a preset bandwidth, and selecting one sub-band as a reference sub-band, for example: the first subband or the last subband is selected as the reference subband. .
