Description

The present invention relates to the field of communication, and more particularly to a common information transmission method and apparatus.

In LTE (Long Term Evolution) systems, base stations use the channel's time-frequency resources to exchange information with the UE. Specifically, a frequency resource in a time-frequency resource is also called bandwidth (Bandwidth, BW, frequency bandwidth, that is, the difference between the highest and lowest frequencies that a network signal can use. May be assigned to base stations and UEs in the form of). For example, after the first UE is connected to the network, the base station has a system bandwidth of 5 MHz (MHz) to the first UE (system bandwidth is the bandwidth of the UE already defined in the LTE system). The system bandwidth is allocated to PRBs (physical resource blocks) numbered from 0 to 24. Therefore, the base station may transmit common information to the first UE on the system bandwidth of the first UE in order to exchange information with the first UE.

As shown in FIG. 1, common information includes SIB (System Information Block), RAR (Radio Access Response), paging information (Paging), or PDCCH (Physical Downlink Control Channel). It can be information transmitted on a channel such as a control channel).

However, in various types of UEs, the bandwidth positions used by the UEs may overlap. For example, the bandwidth of the first UE is the first bandwidth of the PRB numbered 0 to 24 (size is 5 MHz), and the bandwidth of the second UE is numbered 10 to 34. It is the second bandwidth of the PRB given (size is 5MHz), and there is an overlapping 3MHz bandwidth between them. Using the example where the base station sends RAR information to the UE, in this case, the base station separately sends the RAR information to the first UE at the location of the particular RAR resource in the first bandwidth. , RAR information needs to be sent to the second UE at the location of a particular RAR resource in the second bandwidth. As a result, the communication rate between the base station and the UE is affected, increasing the signaling overhead of the base station.

Hereinafter, the technical solution according to the embodiment of the present invention will be clearly and completely described with reference to the accompanying drawings of the embodiment of the present invention. Of course, the embodiments described are merely part of, but not all, of the embodiments of the present invention.

Embodiment 1
The present embodiment of the present invention provides a common information transmission method. As shown in FIG. 2, the method includes:

101: The UE acquires the frequency domain position information of the first transmission bandwidth.

102: The UE determines the size and position of the first transmit bandwidth in the bandwidth of the UE according to the frequency domain position information.

103: The UE receives the common information transmitted by the base station on the first transmission bandwidth according to the size and position of the first transmission bandwidth.

Common information used in this embodiment of the present invention can be classified into three types. The common information transmitted by the base station over the entire bandwidth of the UE is the PCFICH (Physical Control Format Indicator Channel) and PHICH (Physical hybrid ARQ indicator channel) common PDCCH. The first common information, such as information transmitted using (Physical Downlink Control Channel) or common EPDCCH (Enhanced PDCCH). After the base station dynamically configures resources over the entire bandwidth of the UE, the common information transmitted by the base station on a portion of the bandwidth is SIB (System Information Block), RAR (Radio). Second common information such as Access Response, random access response), or paging information (Paging). In addition, the common information transmitted by the base station over the bandwidth at a particular location in the full bandwidth of the UE is MIB (Master Information Block), PSS (Primary Synchronization Signal), SSS. (Secondary Synchronization Signal) or DRS (Discovery Reference Signal), which is the third common information.

Specifically, LTE systems have already defined that there are six sizes of UE standard bandwidth (also known as system bandwidth): 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz. Is. However, the bandwidth used on the base station side is not equal to the bandwidth used by the UE. The bandwidth used on the base station side may be a non-standard bandwidth or a standard bandwidth. In some cases, the different bandwidths used by multiple UEs may overlap. For example, as shown in FIG. 3, the bandwidth used by the base station is a non-standard bandwidth of 7 MHz. The 7MHz bandwidth can be split into two 5MHz standard bandwidths. The two 5 MHz standard bandwidths are the standard bandwidths used by the first UE and the second UE, respectively, with a 3 MHz overlapping bandwidth between the two bandwidths.

If the base station needs to transmit common information (ie, first common information, second common information, or third common information) to the first UE and the second UE, the first Since the position of the system bandwidth used by the UE and the second UE is different, the base station needs to transmit the same common information to the first UE and the second UE separately. As a result, the communication rate between the base station and the UE is affected, increasing the signaling overhead of the base station. In addition, if a resource is used in the overlapping bandwidth to serve the first UE, the base station cannot use the same resource to serve the second UE. In this case, the cell corresponding to the second bandwidth used by the second UE can only be used as the cell providing the secondary service, if the cell is associated with another carrier. Only the second UE can be serviced. As a result, the communication performance between the base station and the UE is affected.

In this embodiment of the invention, the number of UEs is N and can be N = 1, or N = 2, or N = 3, or N ≧ 2. If N = 2 or N ≧ 2, the bandwidths of at least two UEs partially overlap and the two UEs use two different bandwidths or different carriers separately. In this case, all or part of the overlapping bandwidth can be used to send the common information to at least two UEs, so that the base station has the common information to at least two UEs with partially overlapping bandwidths. It can be sent in a shared manner, thereby reducing overhead.

Therefore, the common information transmission method suppresses the repeated transmission of common information from the base station to a plurality of UEs when transmitting the common information in the prior art, and improves the use of resources between the base station and the UE. Will be done.

In step 101, the UE acquires the frequency domain position information of the first transmission bandwidth. The first transmit bandwidth is M PRBs in the bandwidth of the UE, and the frequency domain location information is used to indicate the position and size of the first transmit bandwidth, M> 0.

The size of the first transmit bandwidth is smaller than the size of the bandwidth of the UE (that is, the first transmit bandwidth is placed in the bandwidth of the UE). Specifically, the first transmit bandwidth may be predefined between the UE and the base station, or may be configured by the base station. For example, the UE may receive frequency domain position information that is of the first transmit bandwidth and is transmitted semi-statically by the base station, and the UE may receive the frequency of the first transmit bandwidth. In order to determine the region position information, the characteristic signal may be extracted from the first transmission bandwidth by blind detection. The characteristic signal may include a plurality of different signals. For example, if a predefined sequence is transmitted on a time-frequency resource unit at both ends of the first transmit bandwidth, the position of the first transmit bandwidth and as long as the UE has detected the position of the sequence. You can get the size. The present invention does not limit the specific form of the characteristic signal.

Optionally, the first transmit bandwidth may be formed by M contiguous PRBs that overlap between the bandwidth of the first UE and the bandwidth of the second UE. The first UE and the second UE are UEs that occupy different frequency domain positions.

In step 102, after acquiring the frequency domain position information of the first transmission bandwidth, the UE determines the size and position of the first transmission bandwidth in the bandwidth of the UE according to the frequency domain position information.

In step 101, the position of the first transmit bandwidth may be the start position of the first transmit bandwidth in the bandwidth of the UE or the end position of the first transmit bandwidth in the bandwidth of the UE. The size of the first transmit bandwidth may be several consecutive PRBs, and the UE may be the bandwidth of the UE according to the size and position of the first transmit bandwidth in the frequency domain location information. The size and position of the first transmit bandwidth in may be determined.

For example, using the first UE and the second UE in FIG. 3 as an example, after acquiring the frequency domain position information of the first transmission bandwidth, the first UE obtains the frequency domain position information according to the frequency domain position information. The 15 consecutive PRBs from the 10th PRB to the 24th PRB in the standard bandwidth of 1 UE are determined as the positions of the 1st transmission bandwidth in the standard bandwidth of the 1st UE. After acquiring the frequency domain position information of the first transmission bandwidth, the second UE has 15 pieces from the 0th to the 14th PRB in the standard bandwidth of the second UE according to the frequency domain position information. The contiguous PRB of is determined as the position of the first transmit bandwidth in the standard bandwidth of the second UE.

The standard bandwidths of the first UE and the second UE both include the first transmit bandwidth, but the first transmit bandwidth is the standard bandwidth of the first UE and the second UE, respectively. It can be seen that they are arranged at different positions in. In addition, the bandwidth used by the base station may be non-standard bandwidth, standard bandwidth, and the bandwidth used by the UE may also be standard bandwidth. , May be non-standard bandwidth. The present invention will be described using only examples where the base station uses non-standard bandwidth and the UE uses standard bandwidth. It will be appreciated that three other cases not shown are also applicable to the common information transmission method provided in the present invention.

Further, the first transmission bandwidth may be of any size and may be at any position. For example, the size of the first transmission bandwidth may be 3MHz, 1.4MHz, 2MHz, etc., and the size of the first transmission bandwidth may use the PRB as a unit. For example, the size of the first transmit bandwidth is 15PRB, 6PRB, 8PRB, and so on. Correspondingly, the location of the first transmit bandwidth may be in the center, left, right, center left, or center right of the UE's standard bandwidth.

Preferably, the size of the first transmit bandwidth may be the standard bandwidth already defined in the LTE system, ie 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, or 20MHz. Preferably, the frequency domain structure of the first transmit bandwidth may be the same as the frequency domain structure of the bandwidth having the same size as the size of the first transmit bandwidth in the LTE system. In this way, the base station does not need to modify existing configuration parameters for the UE, and the UE may connect directly to the LTE system over the first transmit bandwidth. As a result, the UE can serve the UE directly over the first transmit bandwidth, thereby improving the compatibility of the LTE system.

In step 103, after determining the size and position of the first transmit bandwidth in the bandwidth of the UE, the UE receives the common information transmitted by the base station on the first transmit bandwidth. The common information can be information shared by different UEs that occupy the first transmit bandwidth.

Continuing to use the first and second UEs in Figure 3 as an example, after separately determining the size and position of the first transmit bandwidth in the respective bandwidths of the first and second UEs. , The first UE and the second UE both receive the common information transmitted by the base station on the first transmission bandwidth. The common information may be any one or more of the above-mentioned first common information, second common information, or third common information. In this way, the base station transmits the common information at once, which causes the base station to transmit the common information to each UE separately, which lowers the communication rate and increases the signaling overhead of the base station. You can avoid the problem. In addition, since the first transmit bandwidth is configured to receive the common information transmitted by the base station in each UE, there is no conflict between the bandwidth resources used by the UE, and the base station has. , Each UE (ie, standalone) can be serviced separately, thereby improving the communication performance between the base station and the UE.

In addition, when receiving the second common information transmitted by the base station on the first transmission bandwidth, the UE receives the second common information on the first transmission bandwidth. Can be dynamically configured. For example, the present embodiment of the present invention provides two methods for receiving a second common information.

Specifically, after determining the size and position of the first transmit bandwidth in the bandwidth of the UE, the UE determines the position of the first transmit bandwidth in the frequency domain position information and the size of the bandwidth of the UE. , The first offset of the first transmit bandwidth may be determined. The first offset is used to indicate the position offset of the first transmit bandwidth in the bandwidth of the UE.

For example, if the size of the UE standard bandwidth is 5 MHz (ie, a PRB numbered from 0 to 24), then the position of the first transmit bandwidth in the UE standard bandwidth is the tenth. It is the 24th PRB from the PRB, and the first offset is 10 (ie, 10-0 = 10) PRB.

In this way, when the UE receives the first position information transmitted by the base station on the first transmission bandwidth, the resource position information is the reception position of the second common information in the bandwidth of the UE. The UE can determine the first position of the second common information in the bandwidth of the UE according to the first position information and the first offset, as it can be used to determine.

For example, the first location information transmitted by the base station is such that the base station transmits the second common information in the 0th to 2nd PRBs of the first transmission bandwidth, and the first of the UEs. If the offset of is 10 PRB, then the first position of the second common information in the UE bandwidth (ie, the actual receive position in the UE bandwidth) is from the tenth in the UE bandwidth. The twelfth PRB, so that the UE receives the second common information transmitted by the base station at the first position in the bandwidth of the UE (ie, the tenth to twelfth PRBs). can.

The first location information may be information shared by a UE that receives the second common information, or the resource location information is information transmitted to all UEs that receive the second common information. You may.

In another method for receiving the second common information provided in the present embodiment of the present invention, the UE is required on the first transmission bandwidth before receiving the second common information. Resource partitioning may be performed based on the resource granularity of a given size according to the above. In this way, the UE can directly receive the second position information transmitted by the base station, which is the second common information. The UE is because the second location is used to indicate the location of the second common information in the first transmit bandwidth, not the location of the second common information in the UE's total bandwidth. , In order to receive the second common information transmitted by the base station at the second reception position, the second position of the second common information in the first transmission bandwidth is directly determined according to the second position information. can.

Further, after receiving the common information transmitted by the base station on the first transmission bandwidth, the UE can also transmit the corresponding uplink information to the base station.

The resource used by the UE to receive the common information (ie, downlink information) transmitted by the base station and the resource used by the UE to transmit the uplink information to the base station have a specific mapping relationship. Because it must be satisfied (for example, if the UE uses the Xth PRB to receive the downlink information, the UE uses the (X + Y) th PRB to receive the corresponding uplink information. Here, X and Y are integers. Note that the mapping relationship is not limited to this, and this is not limited to this in the present invention), 1. When a UE that receives downlink information on its transmit bandwidth and a UE that does not receive downlink information on the first transmit bandwidth transmit uplink information, it is a bandwidth resource (ie, uplink resource). Conflicts can occur between positions).

In this case, the UE is for the second offset, and according to the information transmitted by the base station, the second offset is determined and the second offset is used to transmit the uplink information. Used to determine relative positions in the frequency domain position and in the bandwidth of the UE. The UE may then determine the uplink resource location for transmitting the uplink information to the base station according to the resource location of the received common information and the second offset. Finally, the UE may transmit uplink information to the base station at the uplink resource location. In this way, on the first transmit bandwidth, the plurality of UEs receiving the second common information are used to transmit the uplink information of each of the plurality of UEs according to different second offsets. There is no conflict between the uplink resource locations used by different types of UEs to determine the uplink resource location and thereby send each uplink information of the UE to the base station. Can be certain.

In the common information transmission method provided in the present embodiment of the present invention, the UE acquires the frequency domain position information of the first transmission bandwidth and determines the size and position of the first transmission bandwidth in the bandwidth of the UE. The determination is then made, and then the base station transmits common information to the UE over the first transmit bandwidth. In this way, when the first transmission bandwidth is arranged in the overlapping portion of the bandwidths of the plurality of UEs, the base station can transmit the common information to the plurality of UEs at once. That is, the base station simultaneously transmits the common information to a plurality of UEs in a shared manner, whereby the base station needs to transmit the common information to each UE separately, which lowers the communication rate and reduces the communication rate of the base station. You can avoid the problem of increased signaling overhead.

Embodiment 2
The present embodiment of the present invention provides a common information transmission method. As shown in FIG. 4, the method includes:

201: The base station determines the size and position of the first transmit bandwidth in the bandwidth of the base station.

202: The base station transmits common information to the UE on the first transmit bandwidth according to the size and location of the first transmit bandwidth in the bandwidth of the base station.

Similar to steps 101 through 103 in the embodiments described above, the common information used in this embodiment of the invention is also the first common transmitted using PCFICH, PHICH, common PDCCH, or common EPDCCH. A second, such as at least one of SIB, RAR, or Paging, transmitted over a portion of the bandwidth after the information, or base station dynamically configures resources over the full bandwidth of the UE. Includes common information, or a third common information such as MIB, PSS, SSS, or DRS transmitted by the base station over the bandwidth at a particular location in the full bandwidth of the UE.

In step 201, the base station needs to determine the size and position of the first transmit bandwidth in the bandwidth of the base station before transmitting the common information to the UE. For example, the bandwidth used by the base station is a 7 MHz non-standard bandwidth, and the first transmit bandwidth is located from the 14th PRB to the 24th PRB in the 7 MHz non-standard bandwidth. , Total 2MHz.

Further, the base station determines the frequency domain position information of the first transmission bandwidth, and the frequency domain position information is used to indicate the size and position of the first transmission bandwidth in the bandwidth of the UE. In this way, the base station semi-statically transmits the frequency domain location information to the UE so that the UE follows the size and position of the first transmit bandwidth in the UE bandwidth according to the frequency domain location information. Can be determined, and the base station transmits common information to the UE on the first transmission bandwidth.

Alternatively, the base station may also transmit a characteristic signal to the UE so that the UE performs blind detection according to the characteristic signal and the UE performs the first transmission in the bandwidth of the UE according to the result of the blind detection. The size and location of the bandwidth is finally determined so that the base station transmits common information to the UE over the first transmit bandwidth.

The size of the first transmit bandwidth is smaller than the size of the bandwidth of the UE (that is, the first transmit bandwidth is placed in the bandwidth of the UE). In this embodiment of the invention, the number of UEs is N and can be N = 1, or N = 2, or N = 3, or N ≧ 2. If N = 2 or N ≧ 2, the bandwidths of at least two UEs partially overlap and the two UEs use two different bandwidths or different carriers separately. In this case, all or part of the overlapping bandwidth can be used to send the common information to at least two UEs, so that the base station has the common information to at least two UEs with partially overlapping bandwidths. It can be sent in a shared manner, thereby reducing overhead.

Further, the first transmission bandwidth may be of any size and may be at any position. For example, the size of the first transmission bandwidth may be 3MHz, 1.4MHz, 2MHz, etc., and the size of the first transmission bandwidth may use the PRB as a unit. For example, the size of the first transmit bandwidth is 15PRB, 6PRB, 8PRB, and so on. Correspondingly, the location of the first transmit bandwidth may be in the center, left, right, center left, or center right of the UE's standard bandwidth.

Preferably, the size of the first transmit bandwidth may be the standard bandwidth already defined in the LTE system, ie 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, or 20MHz. Preferably, the frequency domain structure of the first transmit bandwidth may also be the same as the frequency domain structure of the bandwidth having the same size as the size of the first transmit bandwidth in the LTE system. In this way, the base station does not need to modify existing configuration parameters for the UE, and the UE may connect directly to the LTE system over the first transmit bandwidth. As a result, the UE can serve the UE directly over the first transmit bandwidth, thereby improving the compatibility of the LTE system.

In step 202, after the UE determines the size and position of the first transmit bandwidth in the bandwidth of the UE according to the frequency domain location information, the base station has common information (the first) on the first transmit bandwidth. 1 common information, 2nd common information, or 3rd common information) is transmitted to the UE at the same time. Here, there can be multiple UEs.

Specifically, using the first UE and the second UE in FIG. 3 as an example, the size and position of the first transmission bandwidth in the respective bandwidths of the first UE and the second UE are different. After determining, both the first UE and the second UE receive the common information transmitted by the base station on the first transmission bandwidth. In this way, the base station transmits the common information to the first UE and the second UE at once, whereby the base station transmits the common information to each UE separately, so that the communication rate is lowered. However, the problem of increasing the signaling overhead of the base station can be avoided. In addition, since the first transmit bandwidth is configured to receive the common information transmitted by the base station in each UE, there is no conflict between the bandwidth resources used by the UE, and the base station has. , Each UE can be serviced separately, thereby improving the communication performance between the base station and the UE.

In addition, when transmitting the second common information to a plurality of UEs on the first transmission bandwidth, the base station is the band on which the UE receives the second common information on the first transmission bandwidth. The width position can be dynamically configured. For example, the present embodiment of the present invention provides two methods in which the UE is configured by a base station for receiving a second common information.

In the first method, after determining the size and position of the first transmit bandwidth in the bandwidth of the UE, the UE is determined according to the position of the first transmit bandwidth and the size of the bandwidth of the UE. The first offset of the transmission bandwidth of 1 can be determined. The first offset is used to indicate the position offset of the first transmit bandwidth in the bandwidth of the UE. For example, if the size of the UE's standard bandwidth is 5 MHz (ie, a PRB numbered from 0 to 24), then the position of the first transmit bandwidth in the UE's standard bandwidth is the tenth. It is the 24th PRB from the PRB, and the first offset is 10 PRB.

In this way, the base station sends the first location information to the UE so that the UE has a second location in the UE bandwidth according to the first location information and the first offset already determined by the UE. The first position where the common information of is received can be determined. Therefore, the base station may transmit the second common information to the UE at the first receiving position.

For example, the first location information transmitted by the base station is such that the base station transmits the second common information in the 0th to 2nd PRBs of the first transmission bandwidth, and the first of the UEs. If the offset of is 10 PRB, then the first position of the second common information in the bandwidth of the UE is the 10th to 12th PRBs in the bandwidth of the UE, so that the UE is , The second common information transmitted by the base station can be received at the first position in the bandwidth of the UE (that is, the tenth to twelfth PRBs).

The first location information may be information shared by a UE that receives the second common information, or the first location information is information transmitted to all UEs that receive the second common information. It may be.

In another method for receiving the second common information provided in the present embodiment of the present invention, the UE is required on the first transmission bandwidth before receiving the second common information. Resource partitioning may be performed based on the resource granularity of a given size according to the above. In this way, the UE can directly receive the second position information transmitted by the base station, which is the second common information. Since the second location information is used to indicate the location of the second common information in the first transmit bandwidth, rather than the location of the second common information in the UE's total bandwidth, the UE In order to receive the second common information transmitted by the base station at the first reception position, the second reception position of the second common information in the first transmission bandwidth is directly determined according to the second position information. can.

Further, after receiving the common information transmitted by the base station on the first transmission bandwidth, the UE can also transmit the corresponding uplink information to the base station.

The resource used by the UE to receive the common information (ie, downlink information) transmitted by the base station and the resource used by the UE to transmit the uplink information to the base station have a specific mapping relationship. Because it must be satisfied (for example, if the UE uses the Xth PRB to receive the downlink information, the UE uses the (X + Y) th PRB to receive the corresponding uplink information. Here, X and Y are integers. Note that the mapping relationship is not limited to this, and this is not limited to this in the present invention), 1. When a UE that receives downlink information on its transmit bandwidth and a UE that does not receive downlink information on the first transmit bandwidth transmit uplink information, it is a bandwidth resource (ie, uplink resource). Conflicts can occur between positions).

In this case, the UE is for the second offset, and according to the information transmitted by the base station, the second offset is determined and the second offset is used to transmit the uplink information. Used to determine relative positions in the frequency domain position and in the bandwidth of the UE. The UE may then determine the uplink resource location for transmitting the uplink information to the base station according to the resource location of the received common information and the second offset. Finally, the UE may transmit uplink information to the base station at the uplink resource location. In this way, on the first transmit bandwidth, the plurality of UEs receiving the second common information are used to transmit the uplink information of each of the plurality of UEs according to different second offsets. There is no conflict between the uplink resource locations used by different types of UEs to determine the uplink resource location and thereby send each uplink information of the UE to the base station. Can be certain.

In the common information transmission method provided in the present embodiment of the present invention, the UE acquires the frequency domain position information of the first transmission bandwidth and determines the size and position of the first transmission bandwidth in the bandwidth of the UE. The determination is then made, and then the base station transmits common information to the UE over the first transmit bandwidth. In this way, when the first transmission bandwidth is arranged in the overlapping portion of the bandwidths of the plurality of UEs, the base station can transmit the common information to the plurality of UEs at once. That is, the base station simultaneously transmits the common information to a plurality of UEs in a shared manner, whereby the base station needs to transmit the common information to each UE separately, which lowers the communication rate and reduces the communication rate of the base station. You can avoid the problem of increased signaling overhead.

Embodiment 3
The present embodiment of the present invention provides a common information transmission method. As shown in FIG. 5, the method includes:

301: The first UE acquires the frequency domain position information of the first transmission bandwidth, and the first transmission bandwidth is between the bandwidth of the first UE and the bandwidth of the second UE. Formed by overlapping M consecutive PRBs, M> 0.

302: The first UE determines the size and position of the first transmit bandwidth in the bandwidth of the first UE according to the frequency domain position information.

303: The first UE receives the first common information or the third common information transmitted by the base station on the first transmission bandwidth, and the first common information or the third common information is Information shared by the first UE and the second UE.

304a: The first UE determines the first offset of the first transmit bandwidth according to the position of the first transmit bandwidth and the size of the bandwidth of the first UE, and the first offset. Is used to indicate the position offset of the first transmit bandwidth in the bandwidth of the first UE.

304b: The first UE receives the first position information transmitted by the base station on the first transmission bandwidth, and the first position information is the position of the second common information in the bandwidth of the UE. Is used to determine.

304c: The first UE determines the first position of the second common information according to the first position information and the first offset, and the first position is placed in the first transmission bandwidth. ..

304d: The first UE receives the second common information transmitted by the base station at the first position.

305a: The first UE receives the second position information transmitted by the base station on the first transmission bandwidth, and the second position information is the second common information in the first transmission bandwidth. Used to indicate the location of.

305b: The first UE determines the second position of the second common information according to the second position information, and the second position is arranged in the first transmission bandwidth.

305c: The first UE receives the second common information transmitted by the base station at the second position.

In step 301, the first UE acquires the frequency domain position information of the first transmission bandwidth, and the first transmission bandwidth is M PRBs in the bandwidth of the first UE. Preferably, the first transmit bandwidth may be formed by M contiguous PRBs that overlap between the bandwidth of the first UE and the bandwidth of the second UE.

The size of the first transmit bandwidth is smaller than the size of the bandwidth of the first UE (that is, the first transmit bandwidth is placed in the bandwidth of the first UE). Similarly, the size of the first transmit bandwidth is also smaller than the size in the bandwidth of the second UE. Specifically, the UE may receive the frequency domain position information that is of the first transmission bandwidth and is transmitted semi-statically by the base station, and the UE may receive the first transmission band. Blind detection may be performed by extracting a characteristic signal from the first transmission bandwidth in order to determine the frequency domain position information of the width.

In step 302, after acquiring the frequency domain position information of the first transmission bandwidth, the first UE sets the size and position of the first transmission bandwidth in the bandwidth of the first UE according to the frequency domain position information. Is determined.

For example, after acquiring the frequency domain position information of the first transmission bandwidth, the first UE sets the 10th PRB to the 24th PRB in the standard bandwidth of the first UE according to the frequency domain position information. Up to 15 consecutive PRBs are determined as the position of the first transmit bandwidth in the standard bandwidth of the first UE. After acquiring the frequency domain position information of the first transmission bandwidth, the second UE has 15 pieces from the 0th to the 14th PRB in the standard bandwidth of the second UE according to the frequency domain position information. The contiguous PRB of is determined as the position of the first transmit bandwidth in the standard bandwidth of the second UE.

The standard bandwidths of the first UE and the second UE both include the first transmit bandwidth, but the first transmit bandwidth is the standard bandwidth of the first UE and the second UE, respectively. It can be seen that they are arranged at different positions in.

Preferably, the size of the first transmit bandwidth may be the standard bandwidth already defined in the LTE system, ie 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, or 20MHz. Preferably, the frequency domain structure of the first transmit bandwidth may also be the same as the frequency domain structure of the bandwidth having the same size as the size of the first transmit bandwidth in the LTE system. In this way, the base station does not need to modify existing configuration parameters for the first UE, and the first UE connects directly to the LTE system over the first transmit bandwidth. As a result, the first UE can serve the UE directly over the first transmit bandwidth, thereby improving the compatibility of the LTE system.

After performing step 302, the first UE may receive the common information transmitted by the base station on the determined first transmission bandwidth. Common information can be classified into three types. The common information transmitted by the base station over the entire bandwidth of the UE is the first common information such as information transmitted using PCFICH, PHICH, common PDCCH, or common EPDCCH. After the base station dynamically configures resources over the full bandwidth of the UE, the common information transmitted by the base station on a portion of the bandwidth is a second common information such as SIB, RAR, or Paging. be. In addition, the common information transmitted by the base station over the bandwidth at a particular location in the full bandwidth of the UE is a third common information such as MIB, PSS, SSS, or DRS. For example, a MIB, PSS, or SSS can transmit on 72 subcarriers in the middle of the first transmit bandwidth, and a DRS PSS or SSS can transmit on 72 subcarriers in the center of the first transmit bandwidth. The DRS CSI-RS (Channel State Information Reference Signal) can be transmitted on all PRBs in the first transmit bandwidth.

Since the transmission of the second common information needs to be dynamically configured by the base station, the present embodiment of the present invention has two methods for receiving the second common information, namely step 304a. From step 304d and from step 305a to step 305c. If the first UE receives the first common information or the third common information transmitted by the base station on the first transmission bandwidth, step 303 may be performed.

In step 303, after separately determining the size and position of the first transmit bandwidth in the respective bandwidths of the first UE and the second UE, both the first UE and the second UE are second. Receives the first common information or the third common information transmitted by the base station on the transmission bandwidth of 1. In this way, the base station transmits the first common information or the third common information at once, whereby the base station transmits the common information to the first UE and the second UE separately. Therefore, it is possible to avoid the problem that the communication rate is lowered and the signaling overhead of the base station is increased. In addition, the first transmit bandwidth is configured in each UE to receive the first or third common information transmitted by the base station, and thus between the bandwidth resources used by the UE. The base station can serve each UE separately, thereby improving the communication performance between the base station and the UE.

In step 304a, after determining the size and position of the first transmit bandwidth in the bandwidth of the first UE, since the transmission of the second common information needs to be dynamically configured by the base station. , The first UE determines the first offset of the first UE according to the position of the first transmit bandwidth and the size of the bandwidth of the first UE, and the first offset is the first. It can be used to indicate the position offset of the first transmit bandwidth in the bandwidth of one UE.

For example, if the size of the standard bandwidth of the first UE is 5 MHz (ie, PRB numbered from 0 to 24), then the position of the first transmit bandwidth in the standard bandwidth of the first UE. Is the 10th PRB to the 24th PRB, and the first offset is 10PRB.

In addition, the first UE and / or the second UE is also the first in the bandwidth of the first UE and / or the second UE by receiving the first offset transmitted by the base station. Directly determine the position offset of the transmit bandwidth.

In step 304b, the first UE receives the first position information transmitted by the base station on the first transmission bandwidth, and the first position information is the second common information in the bandwidth of the UE. Used to determine the position of. For example, the first location information transmitted by the base station indicates that the base station transmits the second common information in the 0th to 2nd PRBs of the first transmission bandwidth.

Specifically, the first location information may be information shared by the UE that receives the second common information, or the first location information is all that receives the second common information. It may be the information sent to the UE.

In step 304c, after receiving the first position information transmitted by the base station on the first transmission bandwidth, the first UE is subjected to the second common position according to the first position information and the first offset. The first position of the information is determined and the first position is placed in the first transmit bandwidth.

Using step 304a and step 304b described above as examples, the first location information transmitted by the base station is such that the base station uses the second common information from the 0th to the second transmission bandwidth of the first transmission bandwidth. It is transmitted by PRB of, and indicates that the first offset of the first UE is 10 PRB. Therefore, the first position (ie, the actual resource position) of the second common information in the bandwidth of the first UE is the tenth to twelfth PRB in the bandwidth of the first UE.

Similarly, the second UE also uses the same method to determine the first position of the second common information in the bandwidth of the second UE. For example, the first location information transmitted by the base station to the second UE is the second common information transmitted by the base station in the 0th to 2nd PRBs of the first transmission bandwidth. And if it indicates that the first offset of the second UE is 9PRB, then in the second UE, the first position where the second UE receives the second common information in the bandwidth of the second UE. Is the 9th to 11th PRBs in the bandwidth of the 2nd UE. However, in the first transmit bandwidth, the positions of the ninth to eleventh PRBs in the bandwidth of the second UE are the positions of the tenth to twelfth PRBs in the bandwidth of the first UE. And both positions are the 0th to 2nd PRBs of the 1st transmit bandwidth. Therefore, the first UE and the second UE receive the second common information at different positions in the bandwidths of the first UE and the second UE, but at the base station, the second UE. The first position where the first position receives the second common information and the first position where the first UE receives the second common information are actually from the 0th position of the first transmission bandwidth. It turns out that it is the second PRB. Therefore, the base station can transmit the second common information at a time so that both the first UE and the second UE receive the second common information.

In step 304d, after determining the first position of the second common information, the first UE receives the second common information transmitted by the base station at the first position.

Correspondingly, after the second UE in the bandwidth of the second UE determines the actual resource position of the second common information, the second UE is the second UE transmitted by the base station at the actual resource position. Receive the common information of 2. Since the actual resource location where the second common information is received and determined by the first UE and the second UE is the same, the base station transfers the second common information to the first UE and the first UE. It can be transmitted to two UEs at the same time, thereby reducing the resource overhead on the base station side.

In step 305a, when receiving the second common information transmitted by the base station, the first UE does not need to determine the first offset, but is based on the resource granularity of a given size according to the requirements. And divide the resources. For example, the first transmit bandwidth of 3MHz is divided into 15 PRBs according to the PRB particle size.

In this way, the first UE directly receives the second position information transmitted by the base station, which is the second common information on the first transmission bandwidth, and is the second. The location information is used to indicate the receiving location of the second common information in the first transmit bandwidth. For example, the location information of the second common information indicates that the first UE receives the second common information on the second transmit sub-bandwidth of the first transmit bandwidth.

Not surprisingly, there are multiple ways to perform resource partitioning on a first transmit bandwidth based on resource granularity of a given size according to requirements, which is limited by the present invention. It's not a thing. Optionally, the method for performing resource partitioning on the first transmit bandwidth may use the bandwidth resource partitioning method of the first UE to improve compatibility of the LTE system.

In step 305b, the first UE determines the second position of the second common information according to the second position information, and the second position is arranged in the first transmission bandwidth.

Similarly, the second UE can also use the method described above to determine the location of the second common information in the second UE (ie, the actual receive location in the first transmit bandwidth) and base. At the station, the second position where the second UE receives the second common information is the same as the second position where the first UE receives the second common information.

In step 305c, when determining the second position of the second common information in the first transmit bandwidth, the first UE receives the second common information transmitted by the base station at the second position. Can be.

It can be seen that the base station can carry out the method from step 304a to step 304d or from step 305a to step 305c to simultaneously transmit the second common information to the plurality of UEs, thereby reducing the signaling overhead of the base station.

Further, after receiving the common information transmitted by the base station on the first transmission bandwidth, the first UE can also transmit the corresponding uplink information to the base station.

The resource used by the first UE to receive the common information (ie, downlink information) transmitted by the base station and the resource used by the first UE to transmit the uplink information to the base station. , Because it is necessary to satisfy a specific mapping relationship (for example, if the first UE uses the Xth PRB to receive downlink information, the first UE is the (X + Y) th. The PRB of is used to send the corresponding uplink information, where X and Y are integers. The mapping relationship is not limited to this, which is limited in the present invention. Note that this is not the case), the UE that receives the downlink information on the first transmit bandwidth and the UE that does not receive the downlink information on the first transmit bandwidth transmit the uplink information. If so, conflicts can occur between bandwidth resources (ie, uplink resource locations).

In this case, the first UE is for the second offset and determines the second offset according to the information transmitted by the base station, because the second offset transmits the uplink information. It is of the frequency domain position used for and is used to determine the relative position in the bandwidth of the first UE. The first UE may then determine the uplink resource location where the first UE transmits the uplink information to the base station according to the resource location of the received common information and the second offset. Finally, the first UE may transmit uplink information to the base station at the uplink resource location. In this way, on the first transmit bandwidth, the plurality of UEs receiving the second common information are used to transmit the uplink information of each of the plurality of UEs according to different second offsets. There is no conflict between the uplink resource locations used by different types of UEs to determine the uplink resource location and thereby send each uplink information of the UE to the base station. Can be certain.

In the common information transmission method provided in the present embodiment of the present invention, the UE acquires the frequency domain position information of the first transmission bandwidth and determines the size and position of the first transmission bandwidth in the bandwidth of the UE. The determination is then made, and then the base station transmits common information to the UE over the first transmit bandwidth. In this way, when the first transmission bandwidth is arranged in the overlapping portion of the bandwidths of the plurality of UEs, the base station can transmit the common information to the plurality of UEs at once. That is, the base station simultaneously transmits the common information to a plurality of UEs in a shared manner, whereby the base station needs to transmit the common information to each UE separately, which lowers the communication rate and reduces the communication rate of the base station. You can avoid the problem of increased signaling overhead.
